Abstract

The invention relates to mining equipment and can be used to move trolleys at loading, unloading and exchange points of mines. The purpose of the invention is to increase reliability. The pusher contains a movable rod 1, a fist 8, which is pivotally connected to a pull 10 containing strips 15, a washer 16 with springs 11, 12, the free end of which enters the opening 17, where the stops 19 are connected with a hinge 20. When the cam 8 interacts with the movable carriage, the washer 16 rests on the protrusion of the lugs 19, the spring 12 compresses, dampens the blow, during which the bar moves, pushes the stops 19 to the position when the washer 16 loses contact with the protrusion and under the action of the spring 12 moves on t ge 10, pushing stops 19, d Ms hereby the dynamic loads. In the initial position, the pusher is driven by the reverse movement of the rod 1. 2 Il.

The invention relates to mining equipment and can be used to move trolleys at loading, unloading and exchange points of mines.

The purpose of the invention is to increase reliability.

FIG. 1 shows a pusher, a general view; in fig. 2 is a view A of FIG. one.

The pusher includes a rod 1, having supports 2-4 with a chain drive (not shown), moving in guides 5 with a bridge 6, and a guide 7 on which the knuckle 8 is mounted with a finger 9, hingedly connected with a pull 10, on the rod of which, in a certain sequence, springs 11 and 12 are installed, nuts 13 and 14, strips 15 and washer 16 and the free end of which goes into the hole of axis 17, on which hinges 18 have stops 19 having inclined sections D, projections G with spring 20.

When the chain drive of the pusher is turned on, the rod 1 connected to it starts moving before the cam 8 interacts with a trolley (not shown). When it interacts with the car, the ha 10 turns, the rod moves to the right, the washer 16 rests against the protrusion G of the support 19, the spring 12 is compressed, the shock between the cam 8 and the car is dampened. In the process of damping, the strap 15, moving to the right, pushes the stops 19 to the position when the washer 16 loses contact with the protrusion G of the stops 19. Under the action of the spring 12 the washer 16 moves along the rod of the rod 10 to the nut 14, the stops 19 move apart, the fist 8 rotated to support 2, which receives and transmits to the push rod a significantly reduced dynamic load arising from the impact of a fist with a trolley. By moving the car, the push rod 1 returns to its original position, while

the bridge 6, mounted on the rails 5, the fist is placed in a non-working (horizontal) position until it touches the support 4, the spring 11 presses the fist 8 to the support 4, the washer 16 leaves the area of the enveloping surfaces E of the stops 18, which are returned by the action of the spring 20 to the starting position.

When the rod 1 returns to the extreme right position, the finger 9 interacts with the inclined guide 7, as a result of which the fist 8 rotates at a certain angle, the ha ha 10 assumes a position at which the fist 8 under the action of the spring 11 takes an operating position.

Claims (1)

Invention Formula A pusher comprising a knuckle associated with the drive element and a knuckle locking mechanism in the working and non-working position, including a rod located in the plane of the knuckle rotation and pivotally connected to it, fixed axially on the drive element and covered by a spring displaced between the stops, one of which is fixed relative to the drive element, and the other is fixedly connected to the rod, and a rod stop fixed to the drive element, characterized in that In order to increase reliability, the fixation mechanism is provided with a movable washer covering the bar and an additional spring placed between the fixed relative to the rod anvil and a washer movable relative to it, while the stopper of the rod incorporates levers articulated on the drive element the ends of the ledges for engagement with the movable washer and the bevels for engagement with the stop mounted on the rod. 7S jff Wadi DG fu.z.2
