In order to achieve the above purpose, the utility model adopts the following technical solutions: a disassembly tool for fixing connecting bolts in a limited space, including a frame-shaped rod frame with mounting holes at both ends, and a mounting hole at one end of the frame-shaped rod frame A driven shaft is installed inside, a driven flywheel is installed in the middle of the driven shaft, an inner hex socket socket head is installed at one end of the driven shaft, and a driving shaft, the middle part of the driving shaft is equipped with a driving flywheel, a chain is sleeved between the driving flywheel and the driven flywheel, and a wrench is installed at one end of the driving shaft.

Further, the driven shaft is respectively fitted with a driven positioning sleeve on both sides of the driven flywheel, and the driven positioning sleeve and the driven shaft are fixed by jack screws provided on the driven positioning sleeve.

Further, active positioning bushings are fitted on both sides of the driving flywheel on the driving shaft, and the active positioning bushing and the driving shaft are fixed by jacking screws arranged on the active positioning bushings.

Further, the driven shaft and the driven flywheel, the driving shaft and the driving flywheel are all fixed by keys.

Further, the wrench and the socket head are located on both sides of the frame-shaped rod frame.

Further, the frame-shaped pole frame is a square steel with a length of 600-800 mm and a width of 50 mm.

Compared with the prior art, the utility model has the following beneficial effects: the tool for disassembling the fixed connecting bolts in the limited space of the utility model mainly includes a frame-shaped rod frame, a driven shaft, a driven flywheel, an inner hexagon socket head, a driving shaft, and a driving shaft. Flywheel, chain and wrench, match the inner hexagon socket head with the bolts to be disassembled, rotate the wrench, and the driving flywheel drives the driven flywheel to rotate, so that the parts of the equipment in the local space are connected to each other and the fixed bolts are tightened Or unscrew it to achieve the purpose of fixing and disassembling the connecting bolts in the limited space. The utility model is light in weight overall, low in cost, simple in processing, high in disassembly and assembly efficiency, and convenient in manufacture, and can lengthen or shorten the length of the frame-shaped rod frame and the chain in the production process according to the position of the actual disassembled bolts to meet its own needs. needs; it can meet the special needs of maintenance, installation and maintenance of equipment in various fields such as industrial and agricultural enterprises, vehicle and ship industry, etc. It greatly reduces the safety risk of operators when their bodies come into contact with related equipment during the installation, maintenance and repair of mechanical equipment.
