Description

Technical Field

[0001] This utility model relates to the field of escalator roller disassembly and assembly technology, specifically to an auxiliary disassembly and assembly device for escalator rollers. Background Technology

[0002] An escalator is a fixed, electrically driven device consisting of a specially structured chain conveyor and two specially structured belt conveyors, with a circulating movement path, used to transport people upwards or downwards between different floor heights. The steps are one of the components of the escalator. People stand on the steps and move upwards or downwards with them. Rollers are installed at the bottom edge of each step, and the circulating movement of the steps is achieved by the rollers moving along a track.

[0003] Currently, there is a lack of corresponding auxiliary disassembly and assembly equipment when disassembling and assembling ladder rollers. During the disassembly process, the retaining spring on the roller is usually removed first using retaining spring pliers. Then, the bottom of the roller is tapped to separate it from the shaft. Similarly, during installation, the top of the roller is tapped to connect it to the shaft. During the tapping process, the uneven force between the roller and the shaft causes friction, which poses a risk of friction damage to the inner wall of the roller and the outer wall of the shaft.

[0004] Based on this, this utility model designs an escalator roller auxiliary disassembly and assembly device to solve the above problems. Utility Model Content

[0005] In view of the above-mentioned shortcomings of the existing technology, the present invention provides an escalator roller auxiliary disassembly and assembly device.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

The horizontal sliding block slides symmetrically on both sides of the center of the horizontal sliding groove. The horizontal screw thread passes through a set of horizontal sliding blocks in the horizontal sliding groove. The L-shaped plate is fixed on the horizontal sliding block.

[0009] Furthermore, the L-shaped plate includes a side plate and a bottom plate. The side plate is fixed on the horizontal slider, and a vertical adjustment component is installed on the side of the side plate. The bottom plate is connected to the side plate through the vertical adjustment component.

[0010] Furthermore, the vertical adjustment component includes a vertical sliding groove, a vertical sliding block, and a vertical screw.

The vertical blocking blocks are threadedly fixed to both ends of the side plate, and the vertical screw rotates through the vertical blocking blocks.

[0015] Beneficial effects

[0016] 1. By setting up disassembly and assembly parts, when disassembly is required, the disassembly and assembly screw rotates downward and contacts the top of the external rotating shaft that cooperates with the roller. As the disassembly and assembly screw continues to move downward, it generates pressure on the rotating shaft. At this time, the bottom end of the L-shaped plate moves upward and generates a uniform upward force on the roller. As the force increases, the roller and the rotating shaft separate, realizing disassembly. When installation is required, the disassembly and assembly screw is rotated, driving the installation pressure ring to move downward and contact the top of the roller, generating a uniform downward pressure on it, pressing it down to realize installation. Compared with the hammering method, the force is more even during installation and disassembly, reducing the risk of damage.

[0017] 2. By setting horizontal and vertical adjustment components, the position of the base plate can be adjusted according to the diameter and thickness of the roller, so as to facilitate contact between the base plate and the top and bottom of the roller; the horizontal and vertical adjustment components can be easily installed and removed by the through-type horizontal slide groove, vertical slide groove, horizontal block and vertical block.

[0030] In this embodiment of the utility model, when it is necessary to remove the roller, the device is brought close to the roller so that the bottom end of the L-shaped plate 2 is below the roller. Using the disassembly screw 4, the handle 5 is rotated to drive the disassembly screw 4 to rotate downward and contact the top end of the external rotating shaft that is in rotatable with the roller. As the disassembly screw 4 continues to move downward, it generates pressure on the rotating shaft. At this time, the bottom end of the L-shaped plate 2 moves upward and generates a uniform upward force on the roller. As the force increases, the roller and the rotating shaft separate, and the removal is achieved. When it is necessary to install the roller, the roller is placed on the rotating shaft. Using the connecting bolt 10, the mounting pressure ring 7 is fixed to the bottom end of the disassembly screw 4. At this time, the bottom end of the L-shaped plate 2 is placed on the top end of the roller. The disassembly screw 4 is rotated to drive the mounting pressure ring 7 to move downward and contact the top end of the roller, generating downward pressure on it, so that it is pressed down and moved downward to achieve installation.

[0031] In this embodiment of the utility model, by setting up a disassembly and assembly component, when disassembly is required, the disassembly and assembly screw 4 rotates downward and contacts the top of the external rotating shaft that rotates with the roller. As the disassembly and assembly screw 4 continues to move downward, it generates pressure on the rotating shaft. At this time, the bottom end of the L-shaped plate 2 moves upward and generates a uniform upward force on the roller. As the force increases, the roller and the rotating shaft separate, thus achieving disassembly. When installation is required, the disassembly and assembly screw 4 is rotated, driving the installation pressure ring 7 to move downward and contact the top of the roller, generating a uniform downward pressure on it, pressing it down to achieve installation.

[0032] In one embodiment of this utility model, a horizontal adjustment component is provided at the bottom end of the top plate 1. The horizontal adjustment component includes a horizontal sliding groove 11, a horizontal sliding block 12, and a horizontal screw 13. The horizontal sliding groove 11 is symmetrically opened on both sides of the center of the bottom end of the top plate 1. The horizontal sliding block 12 slides symmetrically on both sides of the center of the horizontal sliding groove 11. The horizontal screw 13 is threaded through a set of horizontal sliding blocks 12 in the horizontal sliding groove 11. The L-shaped plate 2 is fixed on the horizontal sliding block 12. By using the horizontal adjustment component and rotating the horizontal screw 13, the position of the two sets of L-shaped plates 2 can be adjusted according to the diameter of the roller to facilitate contact between them and the roller. The L-shaped plate 2 includes a side plate 14 and a bottom plate 15. Plate 15 and side plate 14 are fixed on horizontal slider 12. A vertical adjustment component is installed on the side of side plate 14. The bottom plate 15 is connected to side plate 14 through the vertical adjustment component. The vertical adjustment component includes vertical slide groove 16, vertical slider 17 and vertical screw 18. Vertical slide groove 16 is set at the center of the side of side plate 14. Vertical slider 17 slides in vertical slide groove 16. Vertical screw 18 is threaded through vertical slider 17. The bottom plate 15 is fixed to the side of vertical slider 17. By using the vertical adjustment component and rotating vertical screw 18, the height of bottom plate 15 can be adjusted according to the thickness of roller, so that it can contact the top or bottom of roller.

[0033] In some embodiments, such as Figure 2 and Figure 3 As shown, the inner diameter of the cylinder 8 is equal to the inner diameter of the mounting pressure ring 7. The end of the connecting bolt 10 is hidden inside the cylinder 8. The bottom end of the horizontal slider 12 is flush with the bottom end of the horizontal slide groove 11. The side of the vertical slider 17 is flush with the opening surface of the vertical slide groove 16. The horizontal slide groove 11 is set through both sides of the top plate 1. A set of horizontal slide grooves 11 has horizontal blocking blocks 19 sliding at both ends. The horizontal blocking blocks 19 are threaded and fixed to the side of the top plate 1.

The vertical screw 18 rotates and passes through the vertical blocking blocks 20.

[0034] In this embodiment of the invention, when it is necessary to remove the roller, the device is brought close to the roller. Using the horizontal adjustment component, the horizontal screw 13 is rotated to adjust the position of the two sets of L-shaped plates 2 according to the diameter of the roller, so that the bottom end of the base plate 15 is below the roller. Then, using the vertical adjustment component, the vertical screw 18 is rotated to adjust the height of the base plate 15 according to the thickness of the roller, so that it can contact the top or bottom end of the roller. Finally, using the disassembly screw 4, the handle 5 is rotated to drive the disassembly screw 4 to rotate downward and contact the top end of the external rotating shaft that cooperates with the roller. As the disassembly screw 4 continues to rotate downward... As the L-shaped plate 2 moves downward, it exerts pressure on the rotating shaft. At this time, the bottom end of the L-shaped plate 2 moves upward, generating a uniform upward force on the roller. As the force increases, the roller and the rotating shaft separate, thus achieving removal. When the roller needs to be installed, the roller is placed on the rotating shaft. Using the connecting bolt 10, the mounting pressure ring 7 is fixed to the bottom end of the disassembly screw 4. By rotating the horizontal screw 13, the positions of the two sets of L-shaped plates 2 can be adjusted according to the diameter of the roller, so that the bottom end of the base plate 15 is at the top of the roller. Rotating the disassembly screw 4 drives the mounting pressure ring 7 to move downward and contact the top of the roller, generating a uniform downward pressure on it, thus pressing it down and achieving installation.

[0035] In this embodiment of the utility model, the horizontal sliding groove 11, the vertical sliding groove 16, the horizontal blocking block 19 and the vertical blocking block 20 are arranged through the entire structure, which facilitates the loading and unloading of the horizontal adjustment component and the vertical adjustment component.
