Problems solved by technology
[0002]When the escalator is running, when the step chain breaks, the brake equipped with the escalator quickly stops the operation of the elevator. However, once the brake fails, the step chain after the breakage It will slide down by itself under the weight of the occupants or cargo, and the consequences will be unimaginable, seriously affecting the safety of occupants

The invention discloses a step chain emergency braking device for an escalator. The device can restrain the sliding of a step chain relative to a step track in an emergency and comprises a lateral plate which is located on one side of the step track and extends longitudinally, a cross rod capable of being arranged on the lateral plate in a rotary mode, a braking guide block fixed to the left side of the lateral plate, a braking rod which is suspended at the left end of the cross rod and penetrates through the braking guide block, a pull rod suspended at the right end of the cross rod, and a power system capable of exerting pull force on the pull rod to enable the braking rod to be suspended above the step chain, wherein the two ends of the cross rod are located on the left side and right side of the lateral plate respectively, the power system is communicated with a circuit system of the escalator, and the power system loses power and the braking rod is inserted into the step chain when a power outage occurs in the circuit system. The device can restrain the sliding of the step chain relative to the step track when a brake of the escalator fails, dual safety guarantee is provided for passengers on the escalator, the structure is simple, and implementation is convenient.
Description
technical field [0001] The invention relates to an emergency braking device for a step chain of an escalator. Background technique [0002] When the escalator is running, when the step chain is broken, the brake equipped with the escalator will quickly stop the operation of the elevator. However, once the brake fails, the broken step chain will slide down by itself under the weight of the passengers or goods, which brings The consequences are disastrous, seriously affecting the safety of the occupants. Contents of the invention [0003] The technical problem to be solved by the present invention is to overcome the deficiencies of the prior art and provide an emergency braking device for a step chain of an escalator. [0004] In order to solve the above technical problems, the present invention takes the following technical solutions: [0005] An emergency braking device for a step chain of an escalator, which can limit the sliding of the step chain relative to the step g...
