[0042] Embodiment 3

[0043] This embodiment provides a specific form of the automatic sling based on the embodiment 2.

[0044] As shown in Figure 6 and Figure 7 , the automatic sling comprises a sling frame body 41, a spin lock mechanism 42 and a lock control cylinder 43; the spin lock mechanism 42 is arranged at each corner of the sling frame body 41, and comprises a sling lock head 421, a sling lock sleeve 422, a sliding sleeve 423, a driving handle 424 and a driving connecting shaft 425; the sling lock head 421 is rotatably arranged in the sling lock sleeve 422 and the sliding sleeve 423; the sliding sleeve 423 is fixedly connected with the sling frame body 41; one end of the driving handle 424 is fixedly connected with the sling lock head 421, and the other end is connected with the driving connecting shaft 425; the lock control cylinder 43 is arranged on the sling frame body 41 and connected with the driving connecting shaft 425, and is used to drive the sling lock head 421 to rotate.

[0045] The sling frame body 41 is a rectangular frame structure, and the positions of the four corners correspond to the positions of the top automatic lock connecting blocks 131; the spin lock mechanism 42 is used to dock the container mine car, so as to realize the box docking between the sling and the container mine car, and make the container mine car and the lifting beam form a common movement.

[0046] As shown in Figure 8 and Figure 9 , the spin lock mechanism 42 comprises the sling lock head 421, the sling lock sleeve 422, the sliding sleeve 423, the driving handle 424 and the driving connecting shaft 425. The vertical projection shape of the sling lock head 421 is a rectangle, an approximate rectangle or an irregular special shape, so that the sling lock head 421 can be inserted into or separated from the lock hole when the sling lock head 421 is consistent with the arrangement direction of the lock hole. In this embodiment, the lower end of the sling lock head 421 is a tetrahedron with a conical structure, the upper surface and the opposite two side surfaces are planes, and the remaining side surfaces are conical surfaces.

[0047] Alternatively, the driving handle 424 is connected with the sling lock head 421 through a key.

[0048] The tail end of the sling lock head 421 is provided with a sling nut 426 and a split pin; the sling nut 426 is used as a plug to lock the tail end of the sling lock head 421; the split pin is arranged in the sling lock head 421 and located above the sling nut 426; the split pin is used to stop the sling nut 426 and the tail end of the sling lock head 421, so as to prevent the sling nut 426 from being pulled out.

[0049] In the unlocked state, the sling lock head 421 can be vertically inserted into the top automatic lock connecting block 131. When locked, the driving mechanism makes the driving handle 424 rotate 90 degrees, and the sling lock head 421 rotates 90 degrees in the top automatic lock connecting block 131, thereby being clamped into the top automatic lock connecting block 131 of the container mine car, completing the locking of the sling frame body 41 and the container mine car. When the container mine car is lowered, the driving mechanism makes the driving handle 424 rotate 90 degrees, and the sling lock head 421 rotates 90 degrees in the top automatic lock connecting block 131, and the sling lock head 421 rises to disengage from the top automatic lock connecting block 131, and the sling frame body 41 and the container mine car are separated.

[0050] The lock control cylinder 43 includes a hydraulic pump, a hydraulic cylinder 431, a cylinder rod head 432, a connecting rod 433, and a pipeline 434.

[0051] As shown in Figure 10 , the hydraulic pump is connected with the hydraulic cylinder 431 through the pipeline 434, the cylinder rod head 432 is slidingly arranged in the hydraulic cylinder 431, and the cylinder rod head 432 is hingedly connected with the driving connection shaft 425 through the connecting rod 433. In the embodiment, four lock control cylinders 43 are arranged at the four corners of the sling frame body 41, for driving the lock and unlock of the spin lock mechanism 42.

[0052] When hydraulic oil is delivered from the hydraulic pump to the hydraulic cylinder 431 through the pipeline 434, the volume of liquid in the hydraulic cylinder 431 increases, pushing the cylinder rod head 432 to move and drive the external load to work through the connecting component. When the hydraulic oil flows reversely in the pipeline 434, the cylinder rod head 432 also moves reversely, thereby realizing the reciprocating motion of the cylinder rod head 432. Since the driving connection shaft 425 is connected with the driving handle 424, when the cylinder rod head 432 reciprocates, the driving handle 424 generates rotary motion through the connecting rod 433 and the driving connection shaft 425, and since the driving handle 424 is fixedly connected with the sling lock head 421, the rotation of the sling lock head 421 is realized.

[0053] Alternatively, the automatic sling further includes a lock control explosion-proof valve 44 arranged on the sling frame body 41, and the lock control explosion-proof valve 44 is connected with the hydraulic pump and the hydraulic cylinder 431 through pipelines respectively. The lock control explosion-proof valve 44 can adopt the existing explosion-proof valve products on the market. The explosion-proof valve can control the on-off of fluid, prevent the spin lock mechanism 42 from losing control and unhooking due to sudden rupture of the pipeline, and prevent the hydraulic oil in the pipeline from leaking and polluting, thereby playing the roles of explosion prevention and explosion isolation, and ensuring the safety of the hoisting and unloading process of the monorail mine car.

[0054] In the embodiment, the lock control explosion-proof valve 44 is provided with one, the lock opening oil ports of the four lock control cylinders 43 are connected and connected with the lock opening oil port of the lock control explosion-proof valve 44, and the lock closing oil ports of the four lock control cylinders 43 are connected and connected with the lock closing oil port of the lock control explosion-proof valve 44. In use, the lock opening oil ports of the four lock control cylinders 43 are connected together through pipelines and connected to the lock opening oil port of the lock control explosion-proof valve 44, and the lock closing oil ports of the four lock control cylinders 43 are connected together through pipelines and connected to the lock closing oil port of the lock control explosion-proof valve 44.
