Problems solved by technology
[0002] As we all know, working at heights has always been an industry with certain hidden dangers. The existing protective measures are mainly single protection. Except for special needs, secondary protection is rarely carried out.
From the elevators used to transport goods in the construction industry to the elevators we take every day in life, there are safety hazards
In the machine tool industry, for the lifting parts on the machine tool, the lifting part is usually the main part of the machine tool and the core motion unit of the machine tool. It is especially important to do a good job of protection. In the case of a sudden drop of a heavy object from high altitude , cannot effectively prevent the slide, thus causing hidden dangers to the safety of life and property

The invention relates to a dropproof protecting device, belonging to the high-altitude lifting equipment field. The dropproof protecting device is provided with a chain wheel, wherein the chain wheel is arranged on a shaft through bearings, one end of the shaft is fixed with a support body through keys, the outside surface of the chain wheel is fixed with a disk through bolts, the upper plate body and lower plate body of a centrifugal plate are separately hinged with the side surface of the disk through connection screws, a threaded sleeve is screwed and fixed in the cavity of the shaft through nuts, a rod is inserted in the threaded sleeve, one end of the rod passes through the threaded sleeve and is provided with a baffle plate, the baffle plate is in friction fit with the outside surface of the centrifugal plate, the other end of the rod is arranged on the inside of the support body and is provided with a roller, an inclined plane is processed on the outside wall of the support body, a wedge region is formed between the inclined plane and the inside surface of the chain wheel, a tension spring is pressed into the rod of the cavity of the shaft, and one end of the tension spring is fixed on a nut. When a weight in the high altitude suddenly falls down, the invention can automatically run and effectively prevent the slide.
Description
technical field [0001] The invention relates to the field of high-altitude lifting equipment, in particular to an anti-fall safety device for high-altitude lifting equipment. Background technique [0002] As we all know, working at heights has always been an industry with certain hidden dangers. The existing protective measures are mainly single protection. Except for special needs, secondary protection is rarely carried out. From the elevators used to transport goods in the construction industry to the elevators we take every day in life, there are safety hazards. In the machine tool industry, for the lifting parts on the machine tool, the lifting part is usually the main part of the machine tool and the core motion unit of the machine tool. It is especially important to do a good job of protection. In the case of a sudden drop of a heavy object from high altitude , can not effectively stop the slide, thus causing hidden dangers to the safety of life and property. Conten...
