Handheld long-handle nut pre-tightening equipment for construction site

Abstract

The invention relates to nut pre-tightening equipment, in particular to handheld long-handle nut pre-tightening equipment for a construction site. The technical problem of the invention is to provide the handheld long-handle nut pre-tightening equipment for a construction site, which has an automatic tightening function and is good in tightening effect. The handheld long-handle nut pre-tightening equipment for a construction site comprises a machine body shell, a small motor, a steering mechanism and a driving mechanism, wherein the small motor is arranged on the left side of the bottom of the machine body shell, the steering mechanism is arranged on the left side of the machine body shell, the driving mechanism is arranged between an output shaft of the small motor and the steering mechanism, and a clamping mechanism is arranged in the middle of the bottom of the machine body shell. Through the action of the output shaft of the small motor, the driving mechanism conducts pre-tightening work on a nut on a construction site, the nut can be pre-tightened without manual operation of people, and the labor intensity of people is relieved.

Description

technical field [0001] The invention relates to a nut pre-tightening device, in particular to a hand-held long-handle nut pre-tightening device for a construction site. Background technique [0002] At present, some large-scale machines and labor equipment on most construction sites in our country need to be pre-tightened manually through nuts, so that these machines or equipment can work better on the construction site. [0003] Nowadays, when some equipment in most construction sites in our country needs to be pre-tightened, people hold a belt or other items, and then pre-tighten the nuts on some large-scale equipment or machines on the construction site, and pre-tighten the nuts manually The speed is too slow, which wastes a lot of people's time, and the work efficiency is not high, which is easy to affect the progress of people's later work, and the effect of manually pre-tightening the nut is not very good, and it is easy to loosen, causing unsafe etc. The problem exis...

Problems solved by technology

[0005] In order to overcome the low efficiency of manually pre-tightening the nuts of some large machines or equipment on the construction site, the speed of manual pre-tightening of the nuts is too slow, which will easily affect the progress of people's later work, and the effect of manual pre-tightening of the nuts is poor However, the technical problem of the present invention is to provide a hand-held long-handled nut pre-tightening device for construction sites with automatic tightening function and good tightening effect.
