The spring thruster is arranged close to the transmission rod.

The distance between the two sets of spring buffer systems and the transmission rod is the same.

The utility model has the advantages that:

1. the stability and the reliability of the work of the winch overwinding prevention device introduced by a company are improved; 2. the equipment is convenient to operate, simple in structure and low in raw material price, and is made of the existing materials of a company; 3. the anti-overwinding device can be used as a ground roller and can also play a role of an anti-bumping beam, the safety performance of the anti-overwinding device of the winch is improved, and a series of chain reactions of other safety accidents such as collision of a mine car, equipment collision, wire collision, cables and the like caused by overwinding accidents of the winch are prevented.

in figure 1, a contactor; 2. a wire rope; 3. a transmission rod; 4. a spring pusher; 5. a return spring; 6. a guide rod; 7. a car arrester; 8. a track; 9. a steel wire rope jacket; 10. a loose wheel; 11. a connecting pin; 12. and a buffer block.

Detailed Description

The utility model provides a be used for supplementary prevent that overwinding device adopts car arrester + wire rope + three flexible linkage systems of reset spring to replace original rigidity car stopping fence to through loose wheel 10 improved hoisting wire rope's running height, effectively avoided the promotion in-process touching prevent the overwinding device switch, lead to the unexpected circumstances of parkking of hoist engine. The contactor 1 can freely slide on the guide rod 6, and the transmission rod 3 is tightly welded with the contactor 1 and the connecting pin 11 by adopting I12I-shaped steel, so that the three can be moved at the same time. The design of the steel wire rope outer sleeve 9 is to prevent the steel wire rope from being damaged by friction, the connecting pin 11 is connected with the car arrester 7 through the steel wire rope 2, two sets of spring buffer systems are respectively placed on the inner side 8 of the track, and the buffer block 12 is fixed with the ground by adopting a rivet; the spring propeller 4 is arranged close to the transmission rod 3 in a natural state, and meanwhile, the gap between the two sets of spring buffer systems and the transmission rod 8 is ensured to be consistent. When the tramcar is overwound and the power failure collides with the contactor 1, on the one hand: the transmission rod 3 moves forwards to touch the spring propellers 4 at the two sides, and the kinetic energy is converted into pressure, so that the return spring 5 generates elastic deformation to offset and slow down a part of the energy of the forward movement of the mine car; on one hand: the steel wire rope 2 is under the action of tension, so that the car arrester 7 is pulled up to prevent the mine car from continuing to move forwards. After the mine car is moved away, the return spring 5 drives the spring propeller 4 to automatically return, and the contactor 1 is manually slid to the initial position.

The utility model provides a be used for supplementary prevent that overwinding device can double as car bumper equipment, concrete operation mode: in the normal operation process of the winch, the movable wheel 10 of the device plays the role of a ground roller wheel, rolls along with the sliding of the steel wire rope 2, the steel wire rope 2 is guaranteed not to drag the ground and grind the rope, and meanwhile, the steel wire rope 2 is supported by the movable wheel 10, so that the situation that the steel wire rope 2 shakes vertically and horizontally in the reciprocating motion to touch the switch of the over-winding prevention device is effectively avoided. When the overwinding condition appears in the hoist engine, the mine car front wheel can touch the switch of the overwinding prevention device, the hoist engine can stop working immediately, but the mine car can not stop moving immediately because of inertia, can touch the contactor along with the inertial movement of mine car, change the power of mine car into pressure through the contactor and pass for reset spring 5, reset spring 5 begins to shrink because of pressure, the cushioning effect has been played, simultaneously because contactor 1 is along with the removal of mine car, pull car arrester 7 through wire rope 2, offset the displacement that produces because of the inertial action of mine car, the mine car has effectively been avoided crashing other equipment facilities, the emergence of incident such as wire and cable. After the overwinding accident is solved, the mine car is moved away, the return spring 5 automatically resets, and the contactor 1 is manually reset.
