Description

Technical Field

[0001] This utility model relates to the field of escalator front edge plate technology, and in particular to an escalator front edge plate anti-lifting device. Background Technology

[0002] In the elevator industry, elevator safety is of paramount importance. A common safety hazard is the lifting of the front edge of the escalator, which can not only damage the internal structure of the elevator but also cause pedestrians to fall and get injured.

[0003] In traditional front-edge plate anti-lifting devices, the conventional solution is mainly to increase the weight of the escalator's front-edge plate to prevent it from lifting due to external forces. However, this method often leads to an increase in the overall weight of the components, reducing the elevator's operating efficiency. In order to better address the above problems, promote the development of industry technology, and improve core competitiveness, this application proposes a new composition structure that differs from the existing technology. Utility Model Content

[0004] The purpose of this utility model is to address the shortcomings of existing technologies by proposing an escalator front edge plate anti-lifting device.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. The described embodiments are only some embodiments of the present utility model, not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0024] Reference Figures 1-5 An anti-lift device for the front edge plate of an escalator includes a truss 1. A front edge plate body 2 is located at the top of the truss 1. Two threaded rods 11 are rotatably connected to the bottom of the front edge plate body 2 via bearings. Nuts 14 are threaded onto the outer sides of each of the two threaded rods 11. A cylinder 18 is welded to the bottom of each of the two nuts 14. A conical block 12 is welded to the outer side of each of the two cylinders 18. Fixing blocks 9 are welded to the inner walls of both sides of the truss 1. Stepped insertion holes 16 are opened at the top of each of the two fixing blocks 9, and the conical block 12 is inserted into the stepped insertion holes 16. Nylon is bonded to the inside of each of the two stepped insertion holes 16. The bushing 17, and the nylon bushing 17 is fitted onto the outside of the cylinder 18. In use, the threaded rod 11 is rotated, and the rotational motion is converted into the linear motion of the nut 14 through the threaded transmission of the threaded rod 11, so that the nut 14 moves downward. Then the positive cone block 12 at the bottom of the cylinder 18 is inserted into the stepped insertion hole 16 and the nylon bushing 17, so that the positive cone block 12 passes through the fixing block 9. The nylon bushing 17 is completely fitted onto the outside of the cylinder 18, and the nut 14 abuts against the top surface of the fixing block 9. At this time, the front edge plate body 2 is fixed, so as not to increase the overall weight and reduce the impact on the elevator operating efficiency.

[0025] In this utility model, a fixed seat 13 is welded to the top of each of the two threaded rods 11, and the fixed seat 13 passes through the front edge plate body 2. A T-shaped handle 8 is rotatably connected to one end of each of the two fixed seats 13, which can fold the T-shaped handle 8 through the fixed seat 13. The T-shaped handle 8 is connected to the threaded rod 11 through the fixed seat 13, and the surface of the T-shaped handle 8 is formed with anti-slip texture, which can increase the friction of the operator's hand and prevent slipping. Two guide rods 10 are welded to the top of the front edge plate body 2 on both sides of the two threaded rods 11, and the two adjacent guide rods 10 pass through the nut 14, which can guide the nut 14 through the guide rods 10 to prevent the nut 14 from rotating together when the threaded rod 11 rotates, thereby increasing the stability of the nut 14 when it moves.

[0026] In particular, an inverted cone block 15 is welded to the top of the positive cone block 12 on the outer side of the cylinder 18. In use, the nylon bushing 17 is opened by the inverted cone block 15, thereby releasing the locking of the nylon bushing 17 to the positive cone block 12. Two storage slots 5 are opened on the top of the front edge plate body 2, and the T-shaped handle 8 is located in the storage slot 5. The T-shaped handle 8 can be stored in the storage slot 5, increasing the convenience of the device. Two slide rails 6 are fixed to the top of the front edge plate body 2 by bolts. A movable cover plate 3 is slidably connected between the two slide rails 6. The movable cover plate 3 can cover the storage slots 5 and the T-shaped handle 8 to protect them and increase the safety of the device. A mounting seat is welded to one end of the movable cover plate 3. A screw 4 is threadedly connected to the top of the mounting seat. A threaded hole 7 is opened on the top of the truss 1, and the screw 4 is threadedly connected to the threaded hole 7. The movable cover plate 3 can be fixed to the truss 1 by the screw 4, increasing the stability of the device.

[0027] Working principle: When it is necessary to fix the front edge plate body 2, pull the T-shaped handle 8 out of the storage groove 5 until it is perpendicular to the front edge plate body 2. At this time, rotate the T-shaped handle 8 in the forward direction. Since the surface of the T-shaped handle 8 has anti-slip texture, it can increase the friction of the operator's hand and prevent slippage. At this time, the threaded rod 11 rotates with the T-shaped handle 8. At this time, the nut 14 converts the rotational motion into the linear motion of the nut 14 through the thread transmission of the threaded rod 11, causing the nut 14 to move downward. Then, the positive cone block 12 at the bottom of the cylinder 18 is inserted into the stepped insertion hole 16, and then the nylon is spread open. Bushing 17, at this time, continue to rotate the T-shaped handle 8 until the positive cone block 12 passes through the fixing block 9, the nylon bushing 17 is completely fitted on the outside of the cylinder 18, and the nut 14 abuts against the top surface of the fixing block 9. At this time, the front edge plate body 2 is fixed. When it is necessary to disassemble the front edge plate body 2, rotate the T-shaped handle 8 in the opposite direction, and the nylon bushing 17 is opened by the inverted cone block 15. At this time, continue to rotate the T-shaped handle 8 to make the positive cone block 12 continue to rise until it completely exits the stepped insertion hole 16, thereby releasing the front edge plate body 2 without increasing the overall weight and reducing the impact on the elevator operating efficiency.
