Additional braking device for escalator

Abstract

The invention relates to the technical field of elevator braking equipment and discloses an additional braking device for an escalator. The additional braking device comprises a truss. Driving devices are arranged on two sides of an inner cavity of the truss, lifting ladders are in transmission connection to the outer surfaces of the driving devices, safety pedals are arranged on two sides of the top end of the truss, the inner walls of the safety pedals are connected to the outer walls of the lifting ladders in a clamping manner, a handrail is fixedly mounted at the top end of the truss, and sealing bags are fixedly mounted in the safety pedals. According to the additional braking device for the escalator, by arranging a triggering mechanism, a triggering mandrel is further driven to trigger an emergency braking device as a result of change of a position of hydraulic transmission oil due to change of sizes of the sealing bags. Compared with an existing emergency braking device of the escalator, a button of the emergency braking device is not started manually, the additional braking device is flexible and reliable to respond, and is not affected by external environment and human factors, so that the safety and reliability of the escalator in an operating process are improved effectively.

Description

technical field [0001] The invention relates to the technical field of elevator braking equipment, in particular to an additional braking device for an escalator. Background technique [0002] The escalator is a kind of escalator with circular operation. It is mainly used for electric drive equipment to transport passengers or goods upward or downward. It is widely used in places with large flow of people because of its high transport efficiency and good stability. Public places. [0003] However, due to its own structure, the escalator will set the surface of the elevator ladder into a zigzag structure, which will cause a huge pulling force to run inward at the entrance of the elevator ladder, and there will be a large running gap in it, making During the normal operation of the escalator, there have been accidents where fingers or clothing were involved and caused huge injuries. Although there are emergency brake buttons at the upper and lower ends of the escalator, the e...

Problems solved by technology

[0005] The invention provides an additional brake device for an escalator, which has the advantages of high sensitivity, flexible response, good stability, safety and reliability without artificially starting the emergency brake button, and solves the need for artificial To activate the emergency brake button, but the artificial reaction time is long and the variables are large, and there is no guarantee that in the event of an emergency, there will be passengers at the upper and lower ends of the escalator, and the emergency brake button can be pressed in time
