[0029] The use method of this utility model:

[0030] First of all, it should be made clear that the hanging ring structure involved in the present invention is mainly used for the automatic insertion and removal of the latch 200 at the connection part of the two mine car frames. The present invention takes the installation of the latch 200 during the connection and fixation process of the two mine car bodies 300 and the removal of the latch 200 during the separation process of the two mine car bodies 300 that need to be separated as examples to explain its use method in detail:

[0031] When it is necessary to fix the two mine car bodies 300 together, first start the gantry crane to move the hook removal mechanism 100 to just above one of the latches 200 on the latch 200 placement rack, then start the output shaft of the servo 113 on the hook removal mechanism 100 to rotate the two clamping plates 122 of the pneumatic finger 121 to be parallel to the ring holes of the lifting rings of the latches 200, then start the pneumatic finger 121 to open the two clamping plates 122 until the distance between the insertion rod 123 and the insertion tube 124 is greater than the thickness of the lifting ring, then start the output rod of the telescopic push rod 112 to extend it until the axis of the insertion rod 123 moves to coincide with the axis of the lifting ring, then start the pneumatic finger 121 to push the two clamping plates 122 inward until the insertion rod 123 passes through the lifting ring and is inserted toward it. After the cam 120 is in the state of rotation and the cam 120 is in the state of rotation, the cam 120 is in the state of rotation and the cam 120 is in the state of rotation.

[0032] When the two mine car bodies 300 need to be lifted, the output rod of the telescopic push rod 112 is extended. Due to the interlocking effect of the insertion rod 123 and the insertion tube 124, and the limiting locking effect of the limit rod of the latch 200 and the lock groove 305 in the mine car anti-slip ring 301, the two mine car bodies 300 can be stably lifted by the fixing effect of the latch 200 and the mine car anti-slip ring 301.

[0033] When it is necessary to lift and disassemble the two mine car bodies 300, the output shaft of the steering gear 113 is started to rotate in the opposite direction. The rotation of the output shaft of the steering gear 113 can drive the starting finger to drive the latch 200 at its lower part to drive the limiting rod to rotate in the opposite direction until it coincides with the notch of the lock groove 305. By rotating the plug rod 123 in the opposite direction by a certain angle, the limiting rod of the latch 200 and the lock groove 305 are misaligned, which facilitates the output rod of the telescopic push rod 112 to be retracted upward to pull the limiting rod of the latch 200 out of the lock groove 305, until the lower part of the latch 200 is pulled out from the mine car anti-slip ring 301, thereby realizing the disassembly and separation operation of the two mine car bodies 300.

[0034] The present invention can achieve a firm clamping and fixing operation on the lifting ring on the latch 200 by driving the pneumatic finger 121 to cooperate with the insertion rod 123 and the insertion tube 124 on the clamping plate 122, and cooperate with the mobile grasping mechanism and the position adjustment component 110 to achieve a fast, efficient, convenient and stable removal and plug-in and fixation operation of the latch 200 connecting the two mine car bodies 300. The operation is more convenient and efficient, and solves the problem that the traditional manual removal of the latch 200 increases the labor intensity. If the hook is not removed in time or the mine car travels too fast, it may cause a collision accident between people and vehicles, threatening personal safety.

[0035] Furthermore, it should be noted that, in the description of this utility model, unless otherwise expressly specified or limited, the terms "installed," "connected," and "connected" should be understood in a broad sense.

Those skilled in the art will understand the specific meanings of the above terms in this utility model based on specific circumstances.

[0036] The above is a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principles described in the present invention. These improvements and modifications should also be regarded as the scope of protection of the present invention.
