Wedge block type lifting rod combination

Abstract

The invention discloses a wedge block type lifting rod combination, and belongs to the field of construction tools. The wedge block type lifting rod combination can manually lift and move a heavy object conveniently and quickly. The wedge block type lifting rod combination comprises a pair of long circular lifting rods and a pair of short circular clamping rods, the pair of lifting rods are parallel and horizontal, the pair of clamping rods are further parallel and horizontal, and the clamping rods are located below the lifting rods and the clamping rods and the lifting rods are both in the longitudinal direction; a screw rod with opposite thread turning directions is oppositely connected between the same end of each clamping rod, and a circular pipe, namely a nut pipe, being provided withthreads matched with the threads on the screw rods on the sides, of the inner wall, is in threaded connection with each screw rod; a wedge block with the thin upper part and the thick lower part is arranged on the inner side of the middle of each clamping rod, an elastic hook with a downward opening is arranged on the outer side of each wedge block, the wedge blocks are hung on the clamping rodsthrough hooks, and lower openings of the hooks can bind the clamping rods and prevent the clamping rods from falling off at will so that the lap joint assemblies are combined into a whole; and the lifting rods are fixedly connected to the upper parts of the wedge blocks in a penetrating mode. The wedge block type lifting rod combination is suitable for construction places such as stone sculptures.

Description

technical field [0001] The invention relates to construction equipment, in particular to a wedge-type pole-lifting combination. Background technique [0002] For the loading and unloading or consignment of some heavy objects, and short-distance movement, there are a variety of manpower or motorized tools and equipment to help people perform labor-saving and convenient operations, such as levers, forklifts, loaders, etc. However, such tools are not effective for heavy objects. There are some construction requirements, and not all heavy objects can be applied unconditionally. Specifically, the consignment, movement or loading and unloading of forklifts need to place a bracket that can retain the insertion space under the heavy objects, while the loader requires that the heavy objects are not afraid.

[0002] For the loading and unloading or consignment of some heavy objects, and short-distance movement, there are a variety of manpower or motorized tools and equipment to help people perform labor-saving and convenient operations, such as levers, forklifts, loaders, etc. However, such tools are not effective for heavy objects. There are some construction requirements, and not all heavy objects can be applied unconditionally. Specifically, the consignment, movement or loading and unloading of forklifts need to place a bracket that can retain the insertion space under the heavy objects, while the loader requires that the heavy objects are not afraid. Overturning, dumping and bumping, these requirements are undoubtedly not applicable to the movement of many heavy objects in many occasions; in the stone carving process occasions, many products weigh tens or hundreds of kilograms, and most of them are brittle and afraid of being touched, and the surface is relatively smooth , even if it can be lifted and moved by manpower, it is hard to start because of its heavy features and smooth surface. This requires a special lifting tool, which can be easily operated to realize the lifting of certain stones and other heavy objects. Lifting, moving or loading and unloading
