Anti-fall structure of automatic escalator maintenance port

Abstract

An anti-fall structure of an automatic escalator maintenance port comprises a maintenance port which is arranged at an automatic escalator port and a maintenance blocking plate which is used for blocking the maintenance port during the maintenance of an automatic escalator. A braking guiding rail is arranged on the side wall of the maintenance port and a braking clamping bolt which matches the braking guiding rail is arranged on the side wall of the maintenance blocking plate. The braking guiding rail comprises a plurality of blocking parts which are arranged vertically along the extending direction of the side wall of the maintenance port and pressure changing parts which are vertically arranged along the arrangement direction of the blocking parts in an extending way. By means of the coordination structure of the maintenance blocking plate and the side wall of the maintenance port, a supporting function can play a role in a few sections under the condition that the maintenance blocking plate is under stress but not fixed, so that the impact force caused by the stamping of a person can be greatly reduced and a reverse acting force can be provided to enable the person to leave the maintenance blocking plate in time. Even if the person does not respond for a while, enough time can be provided for the rescue operation of others by the supporting function which plays a role in a few sections.

Description

technical field [0001] The invention relates to the field of elevator equipment, in particular to an anti-drop structure for an escalator maintenance opening. Background technique [0002] The maintenance port of the escalator is generally set at the entrance and exit of the escalator, which is the only way for passengers to get on and off the elevator. When the escalator fails, it generally needs to be repaired from the maintenance port. The blocking plate at the entrance is an iron plate. Many sloppy maintenance personnel often simply put the blocking plate at the maintenance opening when the elevator is not completely repaired. If it is fixed every time, it will actually increase the ineffective work of the maintenance workers. The strength is obviously not necessary, so it is generally required to pay attention to the sign at the maintenance place, but during the debugging stage, many maintenance workers habitually remove the notice sign for debugging. At this time, the ...

[0002] The maintenance port of the escalator is generally set at the entrance and exit of the escalator, which is the only way for passengers to get on and off the elevator. When the escalator fails, it generally needs to be repaired from the maintenance port. The blocking plate at the entrance is an iron plate. Many sloppy maintenance personnel often simply put the blocking plate at the maintenance opening when the elevator is not completely repaired. If it is fixed every time, it will actually increase the ineffective work of the maintenance workers. The strength is obviously not necessary, so it is generally required to pay attention to the sign at the maintenance place, but during the debugging stage, many maintenance workers habitually remove the notice sign for debugging. At this time, the vigilance of passengers will drop. It has caused very serious safety accidents. In recent years, there have been so-called man-eating escalators in China. This is the reason, and the quality of maintenance workers in daily maintenance work is uneven. For an elevator user Impossible. The safety of customers taking the elevator is completely entrusted to the professionalism of the maintenance workers. Therefore, it is necessary to design a structure of the maintenance opening that can reduce the invalid work of the maintenance workers such as repeated fixing, and at the same time ensure the elimination of safety accidents caused by various falls. possibility of
