Abstract
The invention discloses a safety protection structure of an escalator comb plate, which comprises a movable comb plate and a front pedal, wherein a row of leaf-shaped comb teeth are fixed at the front end of the movable comb plate, the rear end of the movable comb plate is designed into a convex structure, a groove is formed at one end, which is connected with the rear end of the movable comb plate, of the front pedal, the rear end of the movable comb plate is embedded into the groove of the front pedal, a spring and an electric trigger switch are arranged in the groove, one end of the spring is in contact with the groove bottom of the groove, the other end of the spring is in contact with the rear end of the movable comb plate, the electric trigger switch keeps a distance with the rear end of the movable comb plate, and is connected with a control loop of the escalator in series to jointly control the escalator, and when the electric trigger switch is pressed by the rear end of the movable comb plate, the escalator stops running. The invention has simple structure and high stability, and the sliding design ensures that the comb plate can quickly respond to abnormal conditions, so that the escalator can quickly treat the abnormal conditions after the comb plate acts, thereby stopping the operation of the escalator.
Description
Technical Field
The invention relates to the technical field of escalator, in particular to a safety protection structure of an escalator comb plate.
Background
The fishback is arranged in the entrance of the escalator, pedestrians can walk through the fishback every time when riding the escalator, but the structure of the existing fishback is quite simple, and when foreign matters are clamped into the fishback, the foreign matters cannot send out a braking signal in time to stop the escalator, so that the escalator safety accident is caused. Such as a shoelace that is too long or is loosened, a high-heeled shoe for women, a trouser leg of a young child, etc., which are possibly caught therein by a walker through the comb plate, if a signal cannot be timely sent out to brake the elevator, a serious accident will occur.
Disclosure of Invention
The invention aims to overcome the defects and shortcomings of the prior art, and provides a safety protection structure of an escalator comb plate, so that when foreign matters are blocked on the comb plate, the foreign matters can be detected, and the escalator can be stopped in time, so that potential safety hazards are eliminated.
In order to achieve the above purpose, the technical scheme provided by the invention is as follows: the utility model provides an escalator broach board safety protection structure, includes that the front end is fixed with the activity broach board and the front footboard of a row of leaf form broach, wherein, the rear end design of activity broach board becomes convex structure, the front footboard is formed with the recess that is used for holding above-mentioned convex structure with the one end that activity broach board rear end links up, the rear end of activity broach board inserts in the recess of front footboard, just built-in spring and the electric trigger switch in the recess, the one end of spring is inconsistent with the recess tank bottom, and its other end is in touch with the rear end of activity broach board, electric trigger switch keeps the interval with the rear end of activity broach board to form the series connection with escalator's control circuit, control escalator jointly, when electric trigger switch is pressed by activity broach board rear end, escalator will stop the operation.
Further, guide sliding strips extending in the groove depth direction are formed on two sides of the groove, and sliding grooves which are in sliding fit with the guide sliding strips are formed on two sides of the movable comb plate, so that the tail end of the movable comb plate slides in the groove more stably and smoothly.
Further, the upper surface of leading-edge footboard is spread and is had the dustproof tectorial membrane of one deck cover recess region, and this dustproof tectorial membrane is in the exhibition state when escalator normal operating, avoids tiny debris to get into in the recess and takes place to block up to influence the slip of movable fishback in the recess.
Further, an anti-slip tooth slot is formed on the upper surface of the front pedal.
Compared with the prior art, the invention has the following advantages and beneficial effects:
the invention has simple structure and high stability, the sliding design enables the comb plate to rapidly respond to abnormal conditions, and the escalator can rapidly process the abnormal conditions after the comb plate acts, thereby stopping the operation of the escalator and having excellent real-time responsiveness.

Detailed Description
The invention will be further illustrated with reference to specific examples.
Referring to fig. 1 to 4, the safety protection structure of the escalator comb plate in this embodiment includes a movable comb plate 1 and a front edge pedal 5, a row of leaf-shaped comb teeth are fixed at the front end of the movable comb plate 1, the rear end of the movable comb plate 1 is designed into a convex structure, a screw hole 3 and an anti-slip tooth socket 7 for fixing on the ground are formed on the front edge pedal 5, a groove 6 for accommodating the convex structure is formed at one end of the front edge pedal 5, which is connected with the rear end of the movable comb plate 1, the rear end of the movable comb plate 1 is inserted into the groove 6 of the front edge pedal 5 to freely slide, a spring 2 and an electrical trigger switch 4 are arranged in the groove 6, one end of the spring 2 is in contact with the bottom of the groove 6, the other end of the spring is in contact with the rear end of the movable comb plate 1, the electrical trigger switch 4 is kept at a certain distance with the rear end of the movable comb plate 1, and is connected with a control loop of the escalator in series, when a foreign object is blocked to the movable comb plate 1, the movable comb plate 1 is in contact with the control loop, the escalator is in a controlled in a common mode, the automatic escalator can be triggered, the system can be directly turned off when the electric trigger system is in a forward sliding state, and the system can be triggered, and the system can be immediately turned off when the automatic comb plate 1 is in a fast running, and the running fault can be triggered.
In addition, in order to make the sliding of the tail end of the movable comb plate 1 in the groove 6 smoother and smoother, both sides of the groove 6 are formed with guide slides 9 extending in the groove depth direction thereof, both sides of the movable comb plate 1 are formed with sliding grooves 10 sliding-fitted with the guide slides 9, and the sliding of the movable comb plate 1 can be made smoother and smoother by the sliding-fitting of the guide slides 9 and the sliding grooves 10.
In addition, a layer of dustproof coating film 8 covering the area of the groove 6 is paved on the upper surface of the front pedal 5, and the dustproof coating film 8 is in a flattening state when the elevator normally operates, so that the effect of preventing tiny sundries such as dust, hair and the like from being blocked in the groove 6 is achieved, and the movable comb plate 1 can work smoothly when abnormal conditions occur.
The above embodiments are only preferred embodiments of the present invention, and are not intended to limit the scope of the present invention, so variations in shape and principles of the present invention should be covered.
