Description

Technical Field

[0001] The utility model belongs to the technical field of hand-held elevators, and in particular relates to a device for changing the shedding of a cover plate of a hand-held elevator. Background Art

[0002] An escalator, or automatic pedestrian elevator, escalator, or escalator is a means of transportation that transports pedestrians in the form of a conveyor belt. Escalators are generally inclined, and pedestrians stand on the automatically moving steps at one end of the escalator and are automatically taken to the other end of the escalator. The steps will remain level all the way. The escalator has handrails on both sides that move synchronously with the steps for users to hold on to. The escalator can always move in one direction, but most of them can have the direction of movement controlled by management personnel according to time, flow of people, and other needs.

[0003] The hand elevator cover, also known as the escalator cover, is an important component of the escalator. Its design and function are directly related to the safety and efficiency of the escalator. The hand elevator cover is a metal plate covering the top of the escalator steps. Its main function is to protect the machine and provide protection for the escalator machine to prevent it from being damaged and contaminated by external personnel and objects. At the same time, it can also play a role in dust prevention, noise reduction, and fire prevention to ensure the normal operation of the escalator machine.

[0004] When the elevator cover plate in the prior art protects the machine installed thereunder, a cover plate with a larger area is usually used to protect the position where the machine is installed. However, the outer wall of the cover plate extends to the outside of the installation groove. After being stepped on for a long time, the edge of the cover plate is easily deformed and warped. On the one hand, the protective effect of the cover plate on the machine at the bottom is reduced. On the other hand, the warped cover plate is not convenient for people to walk on it, and people are likely to kick the warped edge of the cover plate, causing danger. In addition, the cover plate is installed solely based on bolts. Long-term stepping will inevitably cause the bolts to loosen, causing the cover plate to fall off, thereby increasing the occurrence of safety accidents. For this reason, a device for changing the cover plate detachment of a hand-held elevator is proposed. Utility Model Content

[0023] The utility model is further specifically described in detail. The outer wall of the cover body 3 and the inner wall of the mounting groove are slidably fitted, the outer wall of the extension plate 301 and the inner wall of the limiting groove are slidably fitted, threaded holes are provided on the extension plate 301 and the limiting groove, and the two threaded holes are correspondingly arranged, and the fixing bolt 302 fixes the extension plate 301 and the limiting groove through the threaded hole, and the end of the tension spring 304 away from the sliding rod 305 is connected to the inner wall of the mounting cavity 303, the outer wall of the sliding rod 305 and the inner wall of the limiting slide groove are slidably fitted, and the sliding rod 305 and the socket are correspondingly slidably arranged , the sliding magnetic block 306 and the mounting magnetic block 307 are arranged to attract each other with opposite poles, the outer wall of the sliding magnetic plate 308 and the inner wall of the mounting cavity 303 are arranged to slide and fit, the sliding magnetic plate 308 and the inlaid magnetic block 3010 are arranged to attract each other with opposite poles, a square groove is opened on the extension plate 301 above the mounting cavity 303, the top of the sliding magnetic plate 308 extends to the outside of the top of the extension plate 301 through the square groove, and the outer wall of the sliding magnetic plate 308 and the inner wall of the square groove are arranged to slide and fit, the size of the pull block 309 is larger than the size of the square groove, and the bottom of the pull block 309 and the top of the square groove are arranged to slide and fit;

[0024] As can be seen from the above, when installing the cover body 3, the staff fits the outer wall of the cover body 3 to the inner wall of the installation groove. At this time, the extension plates 301 on both sides of the cover body 3 correspond to the limiting grooves, and the extension plates 301 are fitted and installed inside the limiting grooves, and the sliding rod 305 slides correspondingly with the limiting grooves. When the sliding rod 305 corresponds to the socket, according to the effect of opposite poles attracting each other between the sliding magnetic block 306 and the installation magnetic block 307, the sliding rod 305 is inserted into the inside of the socket, and the side of the extension plate 301 is fixed accordingly, thereby limiting and fixing the two sides of the cover body 3;

[0025] It should be noted that: in the initial state, the sliding rod 305 is not plugged into the socket, and one end thereof is in contact with the inner wall of the limiting slide groove. Only when the sliding rod 305 corresponds to the socket, the sliding magnetic block 306 and the mounting magnetic block 307 are attracted to each other by opposite poles, so that the sliding rod 305 is inserted into the socket, and the sliding magnetic plate 308 in the initial state is not in contact with one side of the square groove.

[0027] When disassembling the cover body 3, the fixing bolt 302 is removed, and then the sliding pull block 309 is moved to correspondingly drive the sliding magnetic plate 308 and the sliding plug rod 305 to move, and then the sliding plug rod 305 is separated from the insertion hole, and then the pull block 309 is continuously pulled to make the sliding magnetic plate 308 and the embedded magnetic block 3010 attract each other accordingly, and at this time, the position of the sliding plug rod 305 can be limited so that it is not correspondingly plugged into the insertion hole, and then the cover body 3 can be taken out upwards;

[0028] By setting up the above-mentioned technical scheme, the outer wall of the cover body 3 is utilized to slide and fit with the inner wall of the installation groove, so that the outer wall of the cover body 3 can be prevented from extending to the outside of the installation groove, causing the phenomenon of stepping on the warped edge. On the one hand, the protective effect of the cover body 3 on protecting the machine at the bottom is improved, and on the other hand, it is convenient for people to walk here, avoiding people kicking the warped edge of the cover body 3 to cause dangerous phenomena. The sliding plug rod 305 is used to limit the two sides of the cover body 3, and the fixing bolt 302 is used to fix the cover body 3 for the second time, which improves the stability of the cover body 3 during installation, avoids the cover body 3 from falling, and reduces the occurrence of safety accidents.
