Efficient track brake anti-drop device

Abstract

The invention relates to an efficient track brake anti-drop device. The efficient track brake anti-drop device comprises positioning bolts, a track, a brake mechanism, and a safety rope;the track is aplate type structure with a rectangular cross section, and a plurality of positioning bolts are arranged on the side surfaceof the track,the positioning boltsareevenly distributed along the axial direction of the track and are perpendicular to the axis of the track,a positioning groove is formed in the front end surface of the track,the positioning groove is embedded in the front end surface of the track and evenly distributed along the axial direction of the track,and the brake mechanism comprises a sliding block, a blocking piece, a limiting block, a reset spring,and a brake pad; and a connecting hole is formed in the rear end surface of the brake pad. According to theefficient track brake anti-drop device, disassembly and assembly are quick, the structure is simple, the maintenance cost is low, the braking response is quick, continuous multi-stage braking can also be realized, thus reliable anti-drop protection for working personnel at high altitude can be effectively provided, andsafety of aerial work is greatly improved.

Description

technical field [0001] The invention relates to an anti-falling device, in particular to an anti-falling device for high-efficiency rail braking, which belongs to the technical field of safety protection equipment. Background technique [0002] When working at heights and in mines, anti-fall devices are needed to ensure the personal safety of operators. Especially in mine operations, due to the particularity of the working environment, there is currently no simple and reliable anti-fall device in the industry. [0003] Existing special-purpose track braking anti-falling devices are mostly made up of a hanging ring connected to the safety belt of the human body, a braking arm, a brake pad, a pulley block convenient to slide on the track, and a support for wrapping the track; The structure is relatively complicated and is carried by the personnel themselves, which increases the workload of the user. There are also differential brake-type anti-fall devices on the market, which...

[0003] Existing special-purpose track braking anti-falling devices are mostly made up of a hanging ring connected to the safety belt of the human body, a braking arm, a brake pad, a pulley block convenient to slide on the track, and a support for wrapping the track; The structure is relatively complicated, and it is carried by the personnel themselves, which increases the workload of the user

There are also differential brake-type anti-fall devices on the market, which are generally composed of a casing, a spring, a centrifugal card, a steel cable or a special soft rope. This kind of anti-fall device is expensive, and the differential device must fix the spring. In the upper part of the high place, the spring coil is easy to lose elasticity after long-term use, and the steel strand or special soft rope is easy to rust and muddy, and the maintenance cost is high
