Title: Operating system for mine haulage
IPC: B66B17/20
Filed: 1956-03-05
Abstract: 831,956. Decking apparatus for pit cages. MASCHINENFABRIK R. HAUSHERR & SOHNE G.m.b.H. March 5, 1956 [March 4, 1955], No. 6886/56. Class 78 (4). A charging installation for shaft haulage has hydraulically-operated swinging platforms, a shaft barrier and a tub pusher operated by a single hand control, and means are provided to ensure that the operations occur in the correct sequence. In the form shown, a pump 1 driven continuously by an electric motor 2, takes oil from a container 3 and delivers it under pressure through pipes 5, 6, 7. Pipe 5 leads to a main control piston valve 33, 34 operated by a hand lever 37. On moving the piston to the right the piston 33 first allows fluid to travel along the pipe 5<SP>1</SP> and move the swinging platform 10 into a horizontal position, while the piston 34 cuts off the release pipe 36. Further movement of the piston releases a tub held between the arms 13 of the shaft barrier 12, and still further movement allows fluid to pass along pipe 5<SP>111</SP>, moving piston 20 to the left, and the double piston 22, 24 to the right. This last movement allows pressure fluid to travel along pipe 6 to the reversible motor 16, which drives the tub pusher 17 in the forward direction. On moving the main control in the other direction, fluid is first cut off from pipe 5<SP>111</SP>. This allows the piston 20 to return under the influence of the spring 21 and reverses the direction of the pusher arm 17, which travels to the right until the cam 30, mounted on the pusher carriage, strikes the head of the piston 27. This closes momentarily the release pipe 26 and causes a pressure impulse to travel along the pipe 61, moving the piston 22 to the left and shutting off the motor 16. Further movement of piston 33 to the left allows the arms 13 to return under the action of springs, and the platform 10 to be swung up by its counterweight 11. The pressure pipe 7 feeds a dividing brake 40 controlled by a foot pedal 46. In the normal position fluid flows through pipes 7<SP>1</SP>, 45 and 36 back to the container 3, but when the pedal is depressed pipe 71 is blocked and pressure builds up in 7. This erects the arm 42, holding any tub which comes in contact with it, and also lifts the beam 43 allowing tubs held by this beam to travel forward beyond the pusherarm 17. When the foot pedal is released, the members 42, 43 return under the action of springs.
