Drawings

Fig. 1 is a schematic structural diagram of a lifting tool for lifting wheels.

Fig. 2 is a schematic view of a hanger tool assembly for lifting wheels.

In the figure, the lifting device comprises a lifting ring 1, a lifting ring 2, a lifting rod 3, a movable sliding block 4, a fixed block 5, a lifting hook 6, a lifting hook arm 7, a supporting rod 8, a limiting plate 9, a fastening nut 10 and a limiting end.

Detailed Description

The embodiments of the present invention will be further explained with reference to the accompanying drawings 1 and 2:

the utility model provides a hoist frock for wheel hoist and mount, includes jib 2, cup joints removal slider 3 on jib 2, fixes fixed block 4 and the cable suspension device in 2 bottoms of jib. The hanging device comprises a hook arm 6 and a support rod 7, the hook arm 6 is rotatably connected to a fixing block 4, the top end of the hook arm 6 is hinged to one end of the support rod 7, the other end of the support rod 7 is hinged to a movable sliding block 3, the tail end of the hook arm 6 is bent outwards to form a hook 5, and the hook 5 is used for hooking an inner ring of a wheel.

The opening and closing width of the lifting hook arm is adjusted by adjusting the position of the movable sliding block on the lifting rod, so that the lifting hook hooks the inner ring of the wheel, and the stress angle and the shape of the lifting rod, the supporting rod and the lifting hook arm are kept unchanged under the action of the gravity of the wheel.

The lifting tool for lifting the wheel is preferably a three-jaw lifting tool, so that the firmness of the structure can be ensured, and the lifting operation is simple and easy to implement. The lifting hook arm and the support rod are respectively provided with three lifting hook arms and three support rods, three hinged ends used for being hinged with the support rods are arranged on the periphery of the movable sliding block at equal intervals, and the fixed block and the movable sliding block are correspondingly provided with three hinged ends used for being hinged with the lifting hook arm. If the lifting appliance is a two-claw lifting appliance, namely two lifting hook arms are arranged, the balance is required to be kept when the lifting appliance is used, and the danger of wheel falling caused by hooking and inclining exists. In the case of a multi-jaw spreader, i.e. with more than one hanger arm, the handling is relatively complicated when hooking the wheels, although it is possible to hook securely.

The two ends of the supporting rod are provided with U-shaped hinged ends which are respectively hinged with the hinged end of the movable sliding block and the lifting hook arm.

The lifting hook arm rotates and connects in the hinged end of fixed block, the hinged end of fixed block is the U-shaped and leaves and supplies the lifting hook arm to rotate the clearance.
