Detailed Description

The drawings illustrate specific embodiments of the utility model. As shown in fig. 1 to 8, the lifting appliance for the crane comprises a hinge shaft 2, wherein the hinge shaft 2 is a cylinder, a sleeve 1 is sleeved on the hinge shaft 2, the sleeve 1 is fixed on a lifting rope of the crane, two ends of the sleeve 1 are upwards provided with a guide groove 101 respectively, the guide groove 101 is in a T shape, a limit fork 103 is arranged in the guide groove 101, the limit fork 103 is in a shape shown in fig. 4, a hanging rod 102 is also arranged in the guide groove 101, the hanging rod 102 is positioned at the lower end of the guide groove 101 and is used for hanging the limit fork 103, two groups of limit grooves 201 shown in fig. 5 and 6 are formed in the hinge shaft 2, each group of limit grooves 201 are matched with one limit fork 103, and when the lifting appliance is used, the limit fork 103 is inserted into the limit groove 201 to prevent the hinge shaft 2 from sliding down from the sleeve 1 and inclining; two frames with the same structure and opposite positions are hinged on the hinge shaft 2, and the specific structure of the frames is as follows:

the two 7-type shaft rotating rods 3 are connected through an upper cross beam 5, and the two shaft rotating rods 3 are connected through a handle 7; besides, the lower ends of the two shaft levers 3 can also be connected by a lower cross beam 6.

There are various ways of preventing the shaft drum 4 from being axially displaced, for example, two through holes 12 may be formed in the hinge shaft 2, one at each end, the through hole 12 may be provided with a pin 13, and the pin 13 may be inserted into the through hole 12 after the shaft drum 4 is mounted.

The lower end of the shaft lever 3 is bent inwards, i.e. towards the other frame, to form a bent section 301, the bent section 301 preferably being wedge-shaped.

The outer sides of the bending positions of the two bending sections 301 of one of the frames are respectively hinged with an ear plate 8 or a circular ring, a clamping rod 9 penetrates through the ear plates 8, plugs 901 are arranged at two ends of the clamping rod 9, a clamping groove 10 is arranged at the bending position of the bending section 301 of the other frame, and the clamping rod 9 can be clamped into the clamping groove 10.
