## Background
CROSS-REFERENCE TO RELATED APPLICATIONS
The present application claims priority to Chinese Patent Application No. 201310251576.0, filed Jul. 21, 2013; the disclosure of which is hereby incorporated by reference in its entirety.
TECHNICAL FIELD
The present application relates to high-speed rail rescue equipment, for example, to a new high-speed rail rescue crane and a multifunctional high-speed rail rescue train.
BACKGROUND
A high speed railway, also known as a high-speed rail, refers to a rail track that can be traveled at a speed of beyond 250 km/h. Compared to existing rail tracks, a high-speed rail demands higher accuracy and more precision with respect to the route slope, curve radius, running speed, driving equipment, etc. The high-speed rail line is often contains bridges connected with tunnels and tunnels connected with other tunnels. Many rail tracks are set up on bridges, tunnels and elevated sections. Some rail tracks are even set up in unique terrains such as rivers, lakes and oceans. The train internal track is only 5 minutes. So it is important to ensure security, accuracy, and scientific precision when running a high-speed rail. The high-speed rail provides many advantages, such as being fast, convenient, elegant and comfortable. However, equipment failure, nature disasters and other factors may lead to accidents, which can cause very serious injury. Especially on bridges, tunnels and elevated sections, it is very difficult to rescue the injured from the accidents. The current wreck crane cannot be set up in elevated sections, because the aisles on two sides of the elevated section are not load-bearing. Currently, there are no specialty high speed railway rescue trains for the rescue of high-speed rail accidents. The rescue of the train derailment accident of Eschede of Germany in Jul. 3, 1998, and the train derailment accident of Wenzhou of China in Jul. 23, 2011 happened in a suburb. Therefore, the rescue effort depended mainly on the local rescue equipment and the local community.

DETAILED DESCRIPTION
Reference will now be made in detail to the subject matter disclosed, which is illustrated in the accompanying drawings.
Referring to FIG. 1 and FIG. 3, the present application refers to a new high-speed rail rescue crane comprising: a vehicle equipped with wheels 3 and a concave floor 41 set in the middle of the vehicle floor 4. A steel frame 6 is fixed on the concave floor 41. A cassette deck 5 is set on both sides of the steel frame base 6 and a V-type chute 5.1 is set up on the cassette deck 5. A pedestal floor 8 is fixed on the steel frame base 6, where both sides of a sliding tenon 8.1 is set on. Referring to FIG. 2 and FIG. 3, the sliding tenon 8.1 is engaged with the V-type chute 5.1. The end of the pedestal floor 8 connects with the trip lever 7 of hydraulic cylinder fixed on the steel frame base 6. The trip lever 7 drives the pedestal floor 8. A rotary support 9 is set on the pedestal floor 8, on which the crane 11 is fixed. A crane leg 2 is disposed on the vehicle floor 4. Referring to FIG. 4, there is slot disposed on the end of the leg 2 where the slot couples with rail 1. Bob-weight 10 and drum 11 are disposed on the crane.
The high-speed rail wreck crane is equipped with eight concave legs 2 that are invertedly fastened to the upper apex of the rail and the waist of the I-shaped rail. For example, the concave leg is fastened to the waist of the I-shaped rail by a sliding block. A cab 12 is disposed on the crane, where a signal processor 15, a computer terminal and a controller 16 are disposed. The sensors 14.1-14.4 are disposed on the top of the crane boom 13, the edge of the V-shape chute 5.1, the center of the rotary support 9 and the end of the legs 2. The sensors connect to the computer terminal and controller 16 via a signal processor 15.
According to another aspect of this application, disclosed herein is a multifunctional high-speed rail rescue train, referring to FIG. 5, comprising a rescue command vehicle 101, a medical ambulance 102, a fire fighting vehicle 103, a high-speed rail rescue crane 104, recovery vehicle (crane auxiliary vehicle) 105, a grooming recovery vehicle 106, a drilling mining vehicle 107, and a motor spare vehicle 108. The multifunctional high-speed rail rescue train comprises a vehicle equipped with wheels and a concave floor 41 is disposed in the middle of the vehicle floor 4. A steel frame 6 is fixed on the concave floor 41. A cassette deck 5 is set on both sides of the steel frame base 6 and a V-type chute 5.1 is set up on the cassette deck 5. A pedestal floor 8 is fixed on the steel frame base 6, where both sides of a sliding tenon 8.1 is set on. The sliding tenon 8.1 is engaged with the V-type chute 5.1. The end of the pedestal floor 8 connects with trip lever 7 of hydraulic cylinder fixed on the steel frame base. A rotary support 9 is disposed on the pedestal floor 8, where the crane is fixed. A crane leg 2 is disposed on the vehicle floor 8. There is slot on the end of the leg 2 where the slot couples with rail 1.
The high-speed rail wreck crane is equipped with eight concave legs 2 which are invertedly fastening to the upper apex of the rail and the waist of the I-shaped rail. For example, the concave leg is fasted to the waist of the I-shaped rail by the sliding block. The cab 12 is disposed on the crane, where the crane comprises a signal processor 15, a computer terminal and a controller 16. The sensors 14 are disposed on the top of the crane boom, at the edge of the V-shape chute, in the center of the rotary support and at the end of the legs. The sensor 14 connects to the computer terminal and controller 16 via a signal processor 15.
Referring to FIG. 1 and FIG. 2, to overcome and solve the problem with short legs (the railway line gauge is 1435 mm) which leads to vehicle rollover, the embodiments described herein adopts the following stable and firm measures: the steel frame base of an existing rail rescue crane is disposed on a platform trailer, however, in this application, the steel frame base is fixed on the concave floor 41 to lower the crane barycenter (center of gravity) so that stability is improved. The rail concave platform trailer is refitted to special vehicle for high-speed rail rescue. The vehicle floor 4, 41 and its frame structure are integrated with the steel frame 6, leg 2, vehicle floor 8, rotary support 9 and V-type chute 5.1 to enhance stability. To reduce the diameter of the rotary support 9, the diameter of the rotary support is within the range of 1200 mm to 1300 mm (less than the railway line gauge which is 1435 mm). The center of the rotary support 9 and the crane boom cannot cross the gauge line of the side of the acting force, as this would lead to an unbalanced barycenter. The V-type chute 5.1 is disposed on both ends of the concave floor 41 of the platform trailer to support vehicle floor 8 and its superstructure. The pedestal floor 8 connects with trip lever 7 of hydraulic cylinder to make the pedestal floor 8, rotary support 9 and its superstructure move horizontally which increases the distance of the center of the rotary support 9 to the most stressed legs 2. In doing so, stability is realized and guaranteed. Meanwhile, the computer system of the rescue crane monitors safety and surveils the key parts of the rescue crane via sensors 14.1-14.4 and signal processor 15. The computer terminal and the controller 16 display and warn the user based on the various states of the equipment. This ensures correct operation of the equipment.
Multifunctional marshalling high-speed rail rescue trains 101-108 are satisfied with the command of “parallel operation”, that is, the rescue trains can stop at an adjacent station before arriving at the place of the accident. The train 101-103 of number 1-3 arrive on an adjacent rail to rescue the wounded and evacuate passengers. Number 4-8 of the train 104-108 gets ready to rescue. After the rescue is completed, the rescue within unique terrain begins. The multifunctional high-speed rail rescue trains 101-108 are suitable in unique terrains, such as elevated sections, tunnels, canyons and water. The new high-speed rail rescue crane and multifunctional high-speed rail rescue train are also suitable for the technical rescue of multi-type accident of high-speed rail.
