Arc block type lifting rod combination

Abstract

The invention discloses an arc block type lifting rod combination and belongs to the field of construction tools. The combination can be used for manually lifting up and moving a heavy object conveniently and quickly. The combination comprises a pair of circular lifting rods, the lifting rods are longitudinally arranged side by side at certain intervals in the left-right direction, and screw rodswith opposite thread turning directions are transversely connected to the portions, away from the ends by a certain distance, of rod bodies of the lifting rods in a left-right opposite mode correspondingly. A round pipe, namely a nut pipe, is in threaded connection with each screw rod. Threads matched with threads on the left and right screw rods are machined in the inner walls of the round pipescorrespondingly. A section of sleeve sleeves a middle rod body section of each lifting rod in a clearance fit mode, and the outer side surfaces and the inner side surfaces of the walls of the sleevesare fixedly connected with balance weights and arc blocks correspondingly. The design provided by the invention is suitable for construction sites such as stone carving sites.

Description

technical field [0001] The invention relates to construction equipment, in particular to an arc-block type lifting pole 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. Turning over, dumping and knocking, these requirements are undoubtedly not applicable to the movement of many heavy objects in many occasions; in the stone carving process occ...

[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. Turning over, dumping and knocking, 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 touch, and the surface is relatively smooth , even if manpower can hold up and move it, it is hard to start because of its heavy and smooth surface. This requires a special lifting tool, which can be easily operated to lift some heavy objects such as stones. palletize, move or load
