fig. 1 and 2 are diagrams illustrating a hanger 10 according to an embodiment of the present application, and in combination with fig. 1 and 2, the hanger 10 includes a hook member 100 and an operating member 200. The two hook members 100 are provided, the hook members 100 have opposite hook ends 110 and hinge ends 120, the hinge ends 120 of the two hook members 100 are hinged, the hook ends 110 of the two hook members 100 are oppositely arranged, the operating member 200 has opposite connecting ends 210 and operating ends 220, the connecting ends 210 of the operating member 200 are connected with one hook member 100 of the two hook members 100, and the operating ends 220 of the operating member 200 are arranged on the same side as the other hook member 100 of the two hook members 100. The hooking member 100 corresponding to the connection end 210 of the operation member 200 can move with respect to the other hooking member 100 under the condition that the external force is applied to the connection end 210 of the operation member 200.

Specifically, when the lower side door 20 of the railway freight open wagon is overhauled, the hinged ends 120 of the two hook members 100 of the sling 10 need to be lifted by crane or crane lifting equipment, and the hook ends 110 of the two hook members 100 come close together due to the hinged ends 120 of the two hook members 100 and the action of gravity. The worker needs to stand on one side of the lower side door 20, the lifting device hangs the two hook members 100 of the lifting appliance 10 close together to the side of the lower side door 20 where the worker stands, and simultaneously sets the hook member 100, to which the operation member 200 is not connected, on the side close to the worker, and the worker hangs the hook end 110 of the hook member 100, to which the operation member 200 is not connected, on the side of the lower side door 20 where the worker stands. Since the operation end 220 of the operation member 200 is provided on the same side as the hooking member 100 to which the operation member 200 is not connected, a worker can operate the hooking member 100 corresponding to the connection end 210 of the operation member 200 by holding the operation end 220 of the operation member 200 while stabilizing the hooking member 100 which has been hung. When the worker pushes the operation member 200 in the direction from the operation end 220 to the connection end 210 of the operation member 200, the hooking member 100 corresponding to the connection end 210 of the operation member 200 is away from the other hooking member 100 (hooking member 100 on the same side as the operation end 220 of the operation member 200); when the worker pulls the operation member 200 in a direction from the connection end 210 to the operation end 220 of the operation member 200, the hooking member 100 corresponding to the connection end 210 of the operation member 200 approaches the other hooking member 100. The hooking ends 110 of the hooking members 100 corresponding to the connection ends 210 of the operating members 200 are hung on the opposite sides of the lower side door 20 where the worker stands, thereby hanging the lower side door 20 by the two hooking members 100. With the lifting motion of the lifting apparatus, the hinge ends 120 of the two hook members 100 are hinged, and the hook ends 110 of the two hook members 100 are drawn toward the center under the action of gravity, so as to stably clamp the lower side door 20. Conversely, unhooking of the hooking member 100 on the lower side door 20 corresponding to the connecting end 210 of the operating member 200 can also be achieved by the operating member 200. That is, the lifting appliance 10 provided in the embodiment of the present application can make a worker stand only on one side of the lower side door 20, and can finish the stable hanging of the lifting appliance 10 on the lower side door 20 without frequently moving the position, so that the working difficulty of the operator is reduced, the frequency of body movement is reduced, the working efficiency is improved, and the labor intensity is reduced.

In some embodiments, the connection end 210 of the operating member 200 is rotatably connected or fixedly connected with the corresponding hooking member 100, and the connection end 210 of the operating member 200 is rotatably connected or fixedly connected with the corresponding hooking member 100, so that the hooking member 100 corresponding to the connection end 210 of the operating member 200 can move relative to the other hooking member 100 under the condition that an external force is applied to the connection end 210 of the operating member 200.

In some embodiments, the hook member 100 includes a connecting rod 112 and two hook portions 111, the connecting rod 112 of the hook member 100 connects the two hook portions 111, one end of the two hook portions 111 of the hook member 100 is connected, the hinge end 120 of the hook member 100 is disposed at the connection position of the two hook portions 111, one end of the two hook portions 111 of the hook member 100 away from the hinge end 120 is provided with a hook end 110, and the connecting end 210 of the operating member 200 is rotatably connected or fixedly connected with the connecting rod 112 of the corresponding hook member 100. Since one ends of the two hooking portions 111 of the hooking member 100 are connected, the hinge end 120 of the hooking member 100 is disposed at the connection of the two hooking portions 111 of the hooking member 100, so that the hooking end 110 of the hooking member 100 can be disposed at the other ends of the two hooking portions 111 of the hooking member 100, thereby forming the two hooking ends 110 on the hooking member 100. Thus, when the lower side door 20 is lifted by the lifting appliance 10, the four hook ends 110 of the lifting appliance 10 are hung on two sides of the lower side door 20 in pairs, so that four hanging points are formed on the lower side door 20, and the lifting appliance 10 can lift the lower side door 20 more stably. Thus, the two hook members 100 of the lifting appliance 10 are hung on the two door belts 22 of the lower side door 20 or on the two side edges of the lower side door body 21, so that stable lifting can be performed. In addition, the two hooking portions 111 of the hooking element 100 are connected together by the connecting rod 112 to improve the stability of the hooking end 110 of the hooking element 100.
