Description

Technical Field

[0001] This invention relates to the field of escalator technology, specifically to an escalator drive chain detection device. Background Technology

[0002] An escalator has a pair of step drive sprockets installed on its main shaft. The motor transmits power to the main shaft through the chain and sprockets. After a period of use, the escalator drive chain is prone to loosening, resulting in poor meshing with the sprockets and affecting the escalator's drive.

[0003] Currently, the drive chain is usually inspected manually at regular intervals to check for looseness, which is laborious and time-consuming. Therefore, we propose an escalator drive chain detection device. Summary of the Invention

A screw is vertically inserted through the support frame. The top end of the screw is connected to the inner ring of a bearing. The inner ring of the bearing is rotatably connected to the outer ring of the bearing. The outer ring of the bearing is fixedly connected to the fixing plate. A handwheel is provided at the bottom end of the screw.

[0014] In a preferred embodiment of the escalator drive chain detection device of the present invention, sleeves are provided on both sides of the bottom of the fixed plate, and guide rods are vertically slidably connected to the inner walls of the two sets of sleeves, with the bottom ends of the two sets of guide rods connected to the fixed plate.

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

[0024] Example 1

[0025] Reference Figure 1 An escalator drive chain detection device includes a detection component, including a fixed plate 1, a controller 2 and a laser rangefinder 3 on the fixed plate 1, elastic telescopic components on both sides of the top of the fixed plate 1, and the fixed plate 1 is connected to a bearing seat 7 through the elastic telescopic components. A rotating shaft 8 is rotatably connected to the bearing seat 7, and a gear 9 is sleeved on the rotating shaft 8.

[0026] Gear 9 meshes with drive chain 10;

[0027] The laser rangefinder 3 is electrically connected to the controller 2. The laser rangefinder 3 is directly opposite the bearing seat 7 and can measure the distance between the bearing seats 7. The controller 2 is communicatively connected to the monitoring host of the escalator location. When the drive chain 10 is slack, the elastic telescopic component drives the gear 9 to move vertically, which changes the height between the bearing seat 7 and the laser rangefinder 3. When the changed height signal meets the requirements, that is, when the slack level needs to be checked, the signal is transmitted to the controller 2, and the controller 2 transmits it to the monitoring host of the escalator location to inform the management personnel of the slack status of the drive chain 10, saving time and effort.

[0028] Installation components are used for fixed connection with the escalator frame;

[0029] The adjustment component is connected to both the mounting component and the fixing plate 1.

[0030] The elastic telescopic component includes a fixed rod 4, which is mounted on a fixed plate 1. A connecting plate 5 is vertically slidably sleeved on the top of the fixed rod 4, and a return spring 6 connected to the fixed plate 1 is provided at the bottom of the connecting plate 5. The return spring 6 is sleeved on the outside of the fixed rod 4. The connecting plate 5 is guided by the fixed rod 4 and can move vertically by the return spring 6.

[0031] Both sides of the connecting plates 5 are fixedly connected to the bearing housing 7, so that the connecting plates 5 can drive the bearing housing 7 to move.

[0032] The mounting assembly includes a mounting plate 11, which has screw holes around its perimeter and mounting screws 12 in each screw hole. The mounting plate 11 is fixedly connected to the frame of the escalator by the mounting screws 12 to secure the device.

[0033] The adjustment assembly includes a support frame 13, which is mounted on top of the mounting plate 11. A screw 14 runs vertically through the support frame 13. The top end of the screw 14 is connected to the inner ring 15 of the bearing. The inner ring 15 is rotatably connected to the outer ring 16 of the bearing. The outer ring 16 is fixedly connected to the fixed plate 1. A handwheel 17 is provided at the bottom end of the screw 14. Rotating the handwheel 17 causes the screw 14 to rotate on the support frame 13, which in turn causes the inner ring 15 to rotate on the outer ring 16 of the bearing. This allows the fixed plate 1 to move vertically until the gear 9 just engages the drive chain 10. This ensures that when the device is installed on the frames of different escalators, the gear 9 can engage the drive chain 10 in all cases.

[0034] Sleeves 26 are provided on both sides of the bottom of the fixed plate 1. Guide rods 27 are vertically slidably connected to the inner walls of the two sets of sleeves 26. The bottom ends of the two sets of guide rods 27 are connected to the fixed plate 1. When the fixed plate 1 moves vertically, the sleeves 26 slide on the guide rods 27, which can improve the stability of the fixed plate 1 when it moves.

[0035] Example 2

[0036] Reference Figures 1 to 4 The bottom end of the bearing inner ring 15 extends to below the bearing outer ring 16. An mounting ring 18 located below the bearing outer ring 16 is fixedly sleeved on the bearing inner ring 15. Connecting rods 19 are provided on both sides of the top of the mounting ring 18, and the top ends of both sets of connecting rods 19 are connected to a rotating ring 20. An annular guide groove is provided at the bottom of the fixing plate 1, and the rotating ring 20 is rotatably connected to the annular guide groove. When the screw 14 drives the bearing inner ring 15 to rotate, the mounting ring 18 drives the rotating ring 20 to rotate on the annular guide groove via the connecting rods 19. Two sets of identical insertion holes 25 are provided on both sides of the top of the fixing plate 1, and the bottom ends of the insertion holes 25 are interconnected with the annular guide groove. Insertion rods 22 are vertically slidably connected to each insertion hole 25, and the bottom ends of the insertion rods 22 are provided to connect with the rotating ring 20. The anti-slip pad 23 is contacted, and the top of the insertion rod 22 extends to the top of the fixing plate 1. The top of the insertion rod 22 is connected to the handle 21. The bottom of the handle 21 is provided with a support spring 24 that is sleeved on the outside of the insertion rod 22. The bottom of the support spring 24 is connected to the fixing plate 1. Before turning the handwheel 17, the handle 21 is moved upward so that the anti-slip pad 23 on the insertion rod 22 is disengaged from the top of the rotating ring 20. After the height of the fixing plate 1 is adjusted, the handle 21 is released. Through the elastic force of the support spring 24, the insertion rod 22 passes through the insertion hole 25 and drives the anti-slip pad 23 to contact the rotating ring 20, thereby increasing the friction between the anti-slip pad 23 and the rotating ring 20, preventing the rotating ring 20 from rotating accidentally, and thus preventing the screw 14 from rotating accidentally, thereby improving the stability of the gear 9 during use.

[0037] The rest of the structure is the same as in Example 1.

[0038] Operation process: Install the mounting plate 11 on the escalator frame using the mounting screws 12. Then, based on the distance between the gear 9 and the escalator drive chain 10, rotate the handwheel 17 to make the screw 14 rotate on the support frame 13, causing the inner ring of the bearing 15 to rotate on the outer ring of the bearing 16. This allows the fixing plate 1 to move vertically until the gear 9 just engages the drive chain 10. This ensures that when installing this device on different escalator frames, the gear 9 can engage the drive chain 10. When the drive chain 10 is slack, the spring force of the return spring 6 causes the gear 9 to move vertically, changing the height between the bearing seat 7 and the laser rangefinder 3. When the changed height signal meets the requirements, the laser rangefinder 3 transmits the signal to the controller 2, which then transmits it to the monitoring host at the location of the escalator, informing the management personnel of the slack status of the drive chain 10, saving time and effort.
