Special on-load transportation lifting appliance suitable for multiple working conditions

Abstract

The invention discloses a special on-load transportation lifting appliance suitable for multiple working conditions. The special on-load transportation lifting appliance comprises a cross beam, a moving assembly, idler wheels and an automatic hooking and unhooking assembly, wherein the cross beam is provided with a first rack; the moving assembly comprises a sliding support seat, the sliding support seat is arranged on the cross beam in a sleeving mode and comprises a U-shaped groove body and a second rack, and the sliding support seat can ascend and descend relative to the cross beam to make the second rack can be engaged with and disengaged from the first rack; and the idler wheels are mounted at the upper part of the groove body of the sliding support seat, are arranged on the upper surface of the cross beam and can be in rolling contact with and separated from the cross beam. According to the special on-load transportation lifting appliance suitable for the multiple working conditions, during hoisting, the automatic hooking and unhooking assembly and the moving assembly are hoisted, the rolling wheels are separated from the upper surface of the cross beam, the lower surface of the cross beam is tightly attached to the bottom face of the sliding support seat groove body, and the second rack makes contact with and is clamped with the first rack; and when the lifting point position is adjusted, the automatic hooking and unhooking assembly and the moving assembly descend, the lower surface of the cross beam is separated from the bottom face of the sliding support seat groove body, the second rack is separated from the first rack, and the rolling wheels are in contact fit with the upper surface of the cross beam and can roll relative to the upper surface of the cross beam.

Description

technical field [0001] The invention relates to the technical field of on-load transportation tools, in particular to a special spreader for on-load transportation suitable for multiple working conditions. Background technique [0002] At present, with the enlargement of equipment and the increase of equipment weight, the requirements for spreaders are also higher. The traditional special spreader not only has relatively simple working conditions, but also has strict requirements on the lifting point, and the state cannot be adjusted after lifting. Moreover, many special spreaders need to be disassembled and transported separately due to their relatively large size. [0003] Therefore, there is a need in the art for a special spreader suitable for multi-working conditions, which can eliminate or at least alleviate all or part of the above-mentioned defects in the prior art. Contents of the invention [0004] In view of the above-mentioned technical problems existing in t...
