Falling protector for lifting equipment and control method

Abstract

The invention relates to a falling protector for lifting equipment and a control method. A building climbing frame is mounted on a connecting hole of a guide rail, one end of a lifting guide seat is fixed on a building wall, the other end of the lifting guide seat is hooped on the guide rail, the building climbing frame can move up and down along with a hook of a hoist, and the guide rail moves up and down along with the building climbing frame. The falling protector is mounted on the lifting guide seat; when the building climbing frame moves along with the guide rail at the set constant speed, a plurality of star wheel outer feet on the star wheel of the falling protector can be inserted into a plurality of rectangular holes in the guide rail in sequence, the star wheel is made to rotate, and normal lifting work of the building climbing frame can be achieved; and when the building climbing frame moves downwards at an accelerated speed along with the guide rails, the star wheels are self-locked and cannot rotate, the outer feet of the star wheels are located in the rectangular holes in the guide rails, the guide rails stop moving, the building climbing frame connected with the guide rails stops moving, and self-locking anti-falling can be completed. According to the falling protector for the lifting equipment and the control method, the anti-falling reliability of the falling protector can be enhanced, the structure is simple, pollution can be prevented, and the service life is prolonged.

Description

technical field [0001] The invention relates to a fall prevention device, in particular to a fall prevention device and a control method for lifting equipment. Background technique [0002] Existing anti-fall devices for lifting equipment, such as "building climbing frame anti-fall devices", are large in size and heavy in weight; Due to the impact of the environment, it is often stuck by the mortar or corroded and loses its proper function, resulting in the failure to prevent falling, which is very dangerous! If it is not sealed, the moving parts of the fall arrester will corrode too quickly, the service life will be short, and the parts will be many and complicated, which will increase the cost and affect the normal operation. Contents of the invention [0003] The object of the present invention is to provide a kind of anti-dropping device and control method for lifting equipment, because the present invention uses steel balls, the manufacturing process of steel balls i...
