Description

Anti-skid chain tightener of safety belt Technical Field The utility model belongs to the technical field of high-altitude operation protection, and particularly relates to a safety belt anti-skid chain tightener. Background The safety of the overhead operation is critical, the operators can possibly suffer from falling accidents in a slightly bad pool, life is endangered, the performance of the overhead operation safety belt is directly related to the safety of the operators, the safety belt anti-skid chain can effectively prevent the operators from falling off caused by body shaking and displacement, and the safety belt anti-skid chain plays a key role in ensuring safety; However, the existing safety belt anti-skid chains on the market generally have a serious problem that a rapid tightening structure is lacking, and in emergency situations, such as sudden unbalance of operators and unexpected shaking of bodies, when the rapid tightening of the anti-skid chains is needed to stabilize the bodies, the existing anti-skid chains cannot respond rapidly, and the operators can only slowly adjust the anti-skid chains manually, so that a great deal of time is consumed, the anti-skid chains are seriously influenced to play a protective role in time, and the safety risk of operators in dangerous moments is greatly increased; In daily overhead working, this defect brings a lot of puzzles equally, and long-time overhead working and when the operation gesture frequently adjusts, the operating personnel need not to constantly adjust the tyre chain elasticity according to actual conditions, because lack quick tightening structure, they have to expend a large amount of time and energy and carry out manual operation, this has not only increased physical power consumption, still easily make the operating personnel because of frequent operation distraction, further increase the potential safety hazard, in a word, current safety belt tyre chain is because of lacking quick tightening structure, obvious inadequately in security and use convenience, consequently, need carry out improvement design to it. Disclosure of utility model In view of the problems mentioned in the background, it is an object of the present utility model to provide a safety belt's chain tensioner to solve the problem that the prior art cannot tighten the safety belt's chain rapidly during application. The technical aim of the utility model is realized by the following technical scheme: The anti-skid chain tightener of the safety belt comprises a frame, wherein an adjusting mechanism is movably arranged in the frame, two sides of the interior of the frame are both in sliding connection with a movable frame, a tightening device is fixedly arranged on the inner side of the movable frame, and a safety belt anti-skid chain is arranged in the tightening device; The tightening device comprises a mounting frame, the mounting frame is fixedly mounted on the inner side of the movable frame, a first motor is fixedly mounted on one side of the mounting frame, rotating discs are connected to the two sides of the inner portion of the mounting frame in a rotating mode, a winding frame is fixedly mounted on the inner side of each rotating disc, a through hole is formed in the middle of each winding frame, and a safety belt anti-skid chain is inserted into the through hole and is wound on the outer surface of each winding frame. As the preferable technical scheme, the overlook shape of the winding frame is I-shaped, and the edges and corners of the outer surface of the winding frame are all circular arc-shaped. As the preferable technical scheme, the top and the bottom of frame are all fixed mounting has the installing frame, the outside both ends of installing frame are equipped with the mounting panel.
