Correspondingly, the lock cylinder 13 is a stepped lock cylinder, which is provided with an optical axis section, a thread section and an optical axis section, wherein the outer diameter of the optical axis section is sequentially increased from the head to the tail, the diameter of the optical axis section of the head is equal to the diameter of a lock cylinder hole, the size of the thread section is matched with the size of a screw hole of a lock sleeve so as to be in threaded connection, the diameter of the optical axis section of the tail is smaller than the diameter of the lock sleeve light hole and larger than the diameter of the lock sleeve screw hole, the head end of the optical axis section of the tail can be arranged in the light hole and can be blocked by a step formed at the position of the lock sleeve screw hole and the light hole, and therefore the stroke of the lock cylinder screwed into the lock body and the lock ring is limited.
The head end of the lock key 14 can be sleeved outside the tail of the lock cylinder to screw the lock cylinder to rotate. In design, the lock cylinder 13 and the lock key 14 can be matched by adopting an internal tooth and external tooth meshed structure with three teeth, and each adjacent tooth space can adopt different angles. Or, a plurality of clamping grooves 131 are uniformly distributed on the outer wall of the tail part of the lock cylinder, and a plurality of matched convex edges are arranged on the inner hole wall of the special lock key 14. Or, a plurality of ribs are uniformly distributed on the outer wall of the tail part of the lock cylinder, and a plurality of clamping grooves which are matched with each other are formed in the inner hole wall of the special lock key 14. Alternatively, the lock cylinder and the lock key can be matched in other matching modes in the prior art. Further, the mining winch authorized opening device of the embodiment further comprises a lock cylinder anti-loosening structure which is arranged on the lock body 12 and used for preventing the lock ring 11 from being unlocked. The lock cylinder locking structure can adopt a structure shown in fig. 2, and comprises: the mounting hole is arranged in the lock sleeve 17 in parallel with the screw hole, the tail end of the mounting hole (namely, one side of the mounting hole close to the unthreaded hole) is communicated with the head end of the unthreaded hole, a step is formed between one side far away from the unthreaded hole and the side wall of the unthreaded hole, and the head end of the mounting hole is contacted with the side wall of the lock body; the cylindrical anti-loosening column 16 is arranged in the mounting hole, and the tail end of the anti-loosening column 16 can be propped against a step formed by the mounting hole and the unthreaded hole; a spring is arranged in the mounting hole, the head end of the spring abuts against the side wall of the lock body at the head end of the mounting hole, and the tail end of the spring abuts against the head end of the locking column 16. Correspondingly, a notch for matching with the locking post 16 is formed on the lock cylinder 13. The process of locking the opening device according to this embodiment will be described in detail with reference to fig. 1 to 4.
Firstly, the lock ring 11 is rotated around the lock ring pin 15 to expose the notch on the lock ring 11, and the rings at the two ends of the chain 2 for fixing the winch frame and the steel wire rope clamp of the mining winch are respectively sleeved on the lock ring 11 through the notch of the lock ring 11, then the lock ring 11 is rotated to enable the attaching section of the lock ring 11 to attach to the outer wall of one end of the lock body 12, the notch of the lock ring 11 is rotated to the connecting part of the lock body 12 and is not exposed any more, and the rings at the two ends of the chain are prevented from falling off from the lock ring.
The lock cylinder 13 is then operated with the special key 14 to rotate the lock cylinder 13 in one direction (e.g., clockwise) such that the lock cylinder 13 moves inwardly along the threaded bore of the sleeve 17 (i.e., toward the locking ring), and when the lock cylinder moves inwardly until the locking post mates with the notch in the lock cylinder, the lock cylinder cannot continue to move inwardly. The lock key is pushed inwards by force, so that the lock key overcomes the action of the spring and pushes the locking post inwards, the clamping action of the locking post and the lock cylinder is eliminated, the lock cylinder 13 is continuously rotated while the lock key is pushed by force, the lock cylinder 13 is continuously moved inwards until the optical axis section of the head of the lock cylinder 13 inwards passes through the locking hole of the lock body and the lock cylinder hole 18 of the lock ring, and the lock cylinder is rotationally fixed. At this time, the head end of the optical axis section at the tail of the lock cylinder is blocked by the step formed at the lock sleeve screw hole and the unthreaded hole.
Then, the lock key is slightly pulled outwards, the anti-loose column is clamped into a notch of the lock core under the action of the spring and is clamped with the lock core, at the moment, unless the lock key is used, the lock core cannot rotate in any direction, so that the lock ring 11 cannot rotate around the lock pin shaft 15, two ends of a chain cannot be taken out of the lock ring, and the 'locking' state that the winch frame of the mining winch is fixed with the steel wire rope clamp is realized by locking the lock ring 11 on the lock body 12.
When the lock is to be unlocked, the lock key 14 is inserted into the mounting hole and aligned with the lock cylinder 13, the locking column 16 is pushed inwards, so that the clamping effect of the locking column 10 and the lock cylinder is eliminated, the lock cylinder 13 is rotated in the opposite direction while the lock key is pushed by force, the lock cylinder 13 is unscrewed from the lock sleeve until the head of the lock cylinder 13 is locked Kong Xuanchu even from the lock cylinder hole, the locking effect of the lock cylinder on the lock ring is eliminated, the lock ring is unlocked, the lock ring 11 can rotate around the pin shaft 15, at the moment, the two ends of the chain can be taken out from the lock ring 11, the winch frame and the steel wire rope clamping head can be separated, and the mining small winch can work normally, namely the unlocking is successful.
Therefore, the mining winch authorized opening device is convenient and simple to lock and unlock, and is not easy to damage in the use process.
Although the present utility model has been described in detail hereinabove, the present utility model is not limited thereto, and modifications may be made by those skilled in the art in light of the principles of the present utility model, and it is therefore intended that all such modifications as fall within the scope of the present utility model.
