[0025] Embodiment 2

[0026] On the basis of embodiment 1, as shown in Figure 2 The lifting appliance frame body 1 is a rectangular frame structure, the positions of the four corners thereof correspond to the positions of the four corners of the container mine car, lock holes are arranged at the four corners of the container mine car, and the lock holes are rectangular notches in the embodiment, and the shape and size of the rectangular notches are matched with the lock head 21. The mechanical lock 2 is used for docking the container mine car, realizes the container connection between the lifting appliance and the container mine car, so that the container mine car and the lifting beam form a common movement.

[0027] As shown in Figure 3 and Figure 4 The mechanical lock 2 includes a lock head 21, a lock sleeve 22, a sliding sleeve 23, a driving handle 24 and a driving connecting shaft 25.

[0028] As shown in Figure 5 The lock head 21 includes a rod portion 211 and a head portion 212 at the lower end of the rod portion 211, and the rod portion 211 is rotatably connected with the lock sleeve 22.

[0029] The vertical projection shape of the head portion 212 of the lock head 21 is a rectangle, an approximate rectangle or an irregular special shape, so that when the head portion 212 of the lock head 21 is consistent with the arrangement direction of the lock hole, the lock head 21 can be inserted into or separated from the lock hole.

[0030] In the embodiment, the head portion 212 of the lock head 21 is a tetrahedron with a conical structure, the upper surface and the opposite two side surfaces thereof are planes, and the remaining side surfaces are conical surfaces.

[0031] Alternatively, the drive handle 24 can be connected to the lock head 21 via a key.

[0032] The plug consists of a nut 26 and a cotter pin. The end of the nut 26 is located at the tail end of the lock head 21 and is used to lock the tail end of the lock head 21. The nut 26 and the lock head 21 are threaded together. The cotter pin passes through the lock head 21 and is located above the nut 26. The cotter pin is used to stop the nut 26 from moving to the tail end of the lock head 21 and prevent the nut 26 from coming out.

[0033] The drive handle 24 is positioned between the nut 26 and the sliding sleeve 23.

[0034] In the unlocked state, the lock head 21 can be vertically inserted into the rectangular slot. When locked, the drive mechanism causes the drive handle 24 to rotate 90 degrees, and the lock head 21 rotates 90 degrees along with it in the rectangular slot, thus locking into the rectangular slot of the container mine car, completing the locking of the spreader frame 1 and the container mine car. When the container mine car is lowered, the drive mechanism causes the drive handle 24 to rotate 90 degrees, and the lock head 21 rotates 90 degrees along with it in the rectangular slot. The lock head 21 rises and disengages from the rectangular slot, and the spreader frame 1 and the container mine car disengage.

[0036] Based on embodiment 1 or 2, the driving mechanism is a locking cylinder 3, which includes a hydraulic cylinder 31, a cylinder head 32, a connecting rod 33, and a pipe 34.

[0037] like Figure 6 As shown, the hydraulic system of the monorail crane is connected to the hydraulic cylinder 31 via pipe 34. The cylinder head 32 is slidably disposed within the hydraulic cylinder 31, and the cylinder head 32 is hinged to the drive connecting shaft 25 via connecting rod 33. In this embodiment, four locking cylinders 3 are provided, respectively located at the four corners of the lifting frame 1, for driving the mechanical lock 2 to unlock and lock.

[0038] When hydraulic oil is transported from the hydraulic system of the monorail crane to the hydraulic cylinder 31 through pipe 34, the volume of fluid in the hydraulic cylinder 31 increases, pushing the cylinder head 32 to move and driving the external load to work through the connecting components. When the hydraulic oil flows in the reverse direction in pipe 34, the cylinder head 32 also moves in the reverse direction, thereby realizing the reciprocating motion of the cylinder head 32. Since the drive connecting shaft 25 is connected to the drive handle 24, when the cylinder head 32 reciprocates, the drive handle 24 rotates through the connecting rod 33 and the drive connecting shaft 25. Since the drive handle 24 is fixedly connected to the lock head 21, the rotation of the lock head 21 is realized.
