AI Technical Summary

Problems solved by technology

There are defects in such a brake: First, because the safety regulations clearly stipulate the stopping distance of the escalator, there should be different braking torques corresponding to different storey heights, and the braking torque should be adjustable, but the above-mentioned brakes are difficult to achieve ;Secondly, different operating conditions need to set different braking torques. For example, when the running speed of the escalator is different, the required braking distance is different, so the required braking torque is also different, and the above-mentioned braking device is difficult to reinstall after installation. Set different braking torques according to the actual situation

Embodiment Construction

[0019] Embodiments of the present invention will be described below with reference to the drawings.

[0020] As shown in FIG. 1 , the auxiliary brake 1 is arranged on the upper end of the escalator, and is connected with the motor of the escalator through a chain 2 . refer to figure 2 , the auxiliary brake 1 has a brake wheel 4 and a brake shoe 5 as friction members. The brake shoe 5 is slidably connected to the upright 8 through a guide rail 10 fixed on the upright 8, and acts in association with the spring 9 and the engaging block 6 as the first telescopic part on the upright 8, wherein the engaging block 6 is hinged on the column 8, and can be attracted or released by the electromagnet so as to clamp or release the brake shoe 5. One end of the column 8 is hinged on the fixed base so as to pivot around the fixed base; and the other movable end of the column 8 is connected to the fixed plate 3 in the truss.

[0021] During the normal operation of the escalator, the brake w...

Abstract

The invention discloses an auxiliary brake used for escalators or moving sidewalks and comprises friction pieces which produce brake moment by the fraction of mutual compression and leaning; the friction pieces comprises a brake wheel and a brake boot which can be movably arranged on an upright post. According to the invention, the auxiliary brake comprises a brake moment regulating mechanism used for regulating the brake power of the friction pieces and related and interacted with at least one friction piece. The auxiliary brake is simple in structure and low in cost and can regulate the brake moment conveniently and rapidly. The invention also relates to an escalator or a sidewalk with the auxiliary brake; the escalator or sidewalk can set different brake moments according to different floor heights and has higher security.

Description

technical field [0001] The present invention relates to auxiliary brakes for use on escalators or moving walks. In particular, the invention relates to an auxiliary brake with adjustable braking torque. The invention also relates to escalators and moving walks with such auxiliary brakes. Background technique [0002] As a device for transporting passengers upward or downward, the safety of escalators is very important. The safety device of the escalator is used not only to protect the passengers, but also to provide protection for the escalator equipment itself. As a safety device, the auxiliary brake is an important part that relies on the friction between the two constituting the friction pair to make the mechanism brake. The auxiliary brake is installed in the escalator, which can make the escalator and moving walk play an insurance role in the case of overspeed, reverse, chain breakage, etc. When the full load descends, the braking effect of the auxiliary brake is mor...
