Description

Technical Field

[0001] This utility model relates to the field of testing technology, and more specifically, it relates to a test bench for splicing elevator guide rails. Background Technology

[0002] Elevators are essential equipment in high-rise buildings, facilitating people's movement. Elevators rely on guide rails to ensure safe and stable vertical movement. Therefore, the quality of the guide rails is crucial to elevator safety. The quality of the guide rail splicing performance directly affects the stable lifespan and safety performance of the elevator guide rails during use. Thus, the splicing performance needs to be tested during the production of elevator guide rails.

[0003] Common tests are conducted using test benches. Typical test benches have relatively simple structures. During assembly tests, testers need to move the elevator guide rails onto the bench and perform the assembly test. This process requires manual control throughout, which is labor-intensive and time-consuming. Furthermore, with prolonged work, the precision of the manual control can easily become inaccurate, affecting the test results. In actual use, depending on the requirements, elevator guide rails may need to be installed at different tilt angles, requiring assembly under tilt conditions. Most common test benches are simple flat surfaces, unable to adjust the surface tilt according to needs, limiting versatility and the ability to conduct tests under various conditions. Additionally, elevator guide rail models are not standardized depending on the application. Although most are T-shaped structures, their sizes vary. When fixing the guide rails, poor fit between the fixing structure and the guide rail may occur, affecting the stability of the guide rails during the assembly test and impacting the overall test results.

[0030] Please see Figure 1-5 A test bench for splicing elevator guide rails includes a frame 1, a drive screw 2 in the frame 1 with threads at both ends of the drive screw 2 facing each other, a first drive motor 3 on the frame 1 with the output end of the first drive motor 3 cooperating with the drive screw 2, movable seats 4 at both ends of the frame 1 cooperating with the drive screw 2, a second drive motor 5 on the movable seat 4 with a clamping screw 6 at the output end of the second drive motor 5 with threads at both ends of the clamping screw 6 facing each other, and clamping plates 7 slidably connected at both ends of the movable seat 4 with the clamping plates 7 cooperating with the clamping screw 6.

[0031] The frame 1 includes a support frame 8 and a movable frame 9. The drive screw 2 and the first drive motor 3 are both mounted on the movable frame 9. One end of the movable frame 9 is rotatably connected to the support frame 8. The support frame 8 is equipped with a support cylinder 10. The upper end of the support cylinder 10 is equipped with a support block 11. The lower end of the movable frame 9 is equipped with a contact plate 12. The support block 11 cooperates with the contact plate 12.

[0032] In this embodiment, the frame 1 supports the equipment. When splicing the guide rails, two sets of guide rails are placed on the movable seats 4 at both ends. The second drive motor 5 is controlled to work, causing the second drive motor 5 to drive the clamping screw 6 to rotate. The clamping screw 6 cooperates with the clamping plates 7 at both ends to provide power, causing the clamping plates 7 at both ends to move inward synchronously and contact the elevator guide rail, pushing the elevator guide rail to move towards the center. Through the pushing and pressing of the clamping plates 7 at both ends, the guide rail is fixed and aligned to the center. Then, the first drive motor 3 is controlled to work, causing the first drive motor 3 to control the drive screw 2 to rotate. Through the cooperation of the drive screw 2 with the movable seats 4 at both ends, power is provided, causing the movable seats 4 to move towards the center with the fixed guide rail, thereby splicing the guide rails.

[0033] More specifically, during the assembly of the guide rails, the support cylinder 10 is controlled to work, causing the support cylinder 10 to drive the support block 11 to rise. The support block 11 cooperates with the contact plate 12 to provide thrust, lifting one end of the movable frame 9, causing the movable frame 9 to rotate along the frame 1, thereby causing the support structure to deflect and change angle, providing different environments for guide rail assembly tests.

[0034] Please see Figure 1 As one implementation method: the clamping plate 7 is provided with an adjusting screw 13. Multiple sets of adjusting screws 13 are provided and are evenly spaced on the clamping plate 7. They are threadedly engaged with the clamping plate 7. One end of the adjusting screw 13 is provided with a rotating handle 14, and the other end is provided with a clamping block 15.

[0035] Specifically, before fixing the guide rail, the adjusting screw 13 is adjusted according to the shape of the guide rail. The adjusting screw 13 cooperates with the clamping plate 7 and moves inward to the clamping plate. Through the cooperation of multiple clamping blocks 15, a contact structure with the shape of the composite elevator guide rail is formed, which makes it easy to clamp and fix the guide rail.

[0036] Please see Figure 5 As a further embodiment of the clamping block: the clamping block 15 includes a pressure block 16 and a contact rubber block 17. The pressure block 16 is rotatably connected to the adjusting screw 13, and the contact rubber block 17 is fixedly connected to the other end of the pressure block 16.

[0037] Specifically, the pressure block 16 moves by cooperating with the adjusting screw 13, and the pressure block 16 is pressed against the guide rail by the contact rubber block 17, which also improves the contact effect and anti-slip ability.

[0038] Please see Figure 1 and Figure 2 As a further embodiment of the rack: the rack 1 is provided with plug-in seats 18 at both ends, and a limiting plate 19 is provided between the plug-in seats 18. The limiting plate 19 and the plug-in seats 18 can be detachably connected, and two sets of limiting plates 19 are provided, distributed on both sides of the center of the rack 1.

[0039] Specifically, with the support of the plug-in 18, the limiting plate 19 is placed on the plug-in 18, so that the limiting plate 19 is horizontally placed between the movable seats 4. When placing the elevator guide rail, the splicing end of the guide rail is attached to the limiting plate 19, and the stability of the guide rail when fixed is adjusted so that the subsequent splicing can be carried out stably.

[0040] Please see Figures 2-5 As a further embodiment of the movable seat: the lower end of the movable seat 4 is provided with a support slider 20, the support slider 20 is slidably engaged with the frame 1 and threadedly engaged with the drive screw 2, and the frame 1 is provided with a support plate 21, which is engaged with the support slider 20.

[0041] Specifically, the movable seat 4 cooperates with the drive screw 2 through the support slider 20, and the movable seat 4 is supported by the support slider, so that the support slider moves the movable seat 4 stably, avoiding pressure on the drive screw 2, so that the drive screw 2 can drive stably and ensure the stable movement of the movable seat 4.

[0042] Please see Figure 4 and Figure 5 As a further embodiment of the movable seat: the frame 1 is provided with a guide rod 22, and the support slider 20 has sliding holes 23 at both ends, and the sliding holes 23 are slidably engaged with the guide rod 22.

[0043] Specifically, when the support slider 20 moves, it cooperates with the guide rod 22 through the sliding hole 23. Under the restriction and guidance of the guide rod 22, the support slider 20 remains stable, which in turn drives the moving seat 4 to move stably.

[0044] Please see Figure 5 As a further embodiment of the support slider: the lower end of the support slider 20 is provided with a movable pulley 24, and the support slider 20 contacts and cooperates with the support plate 21 through the movable pulley 24.

[0045] Specifically, the support slider 20 contacts the support plate 21 through the movable pulley 24. The rotation of the movable pulley 24 reduces the friction of the simple contact structure, making the movement smoother.

[0046] Please see Figure 3 As a further implementation of the support block: the support block 11 is provided with a support roller 25, which cooperates with the contact plate 12.

[0047] Specifically, when the support block 11 moves upward, it contacts the contact plate 12 through the support roller 25. When the contact plate 12 is rotated by the thrust, the arc surface of the support roller 25 can adapt to the contact in different directions and positions, and can also adapt to the relative movement caused by the change of contact position, so that the cooperation between the equipment remains smooth.

[0048] In summary, when the entire device is in use (or running):

[0049] When using the equipment, the frame 1 supports each piece of equipment, and the electrical equipment is connected to the external power supply. Before fixing the guide rail, the adjusting screw 13 is pre-adjusted according to the shape of the guide rail. By rotating and controlling the rotation of the adjusting screw 13, the adjusting screw 13 is engaged with the clamping plate 7. Under the driving action of the thread, it moves inward to the side of the clamping plate. Through the cooperation of multiple independent clamping blocks 15, different clamping plates 7 are stopped in different positions, forming a contact structure with a composite elevator guide rail shape, which facilitates the clamping and fixing of the guide rail. The limiting plate 19 is placed on the insertion seat 18 in advance, so that the limiting plate 19 is horizontally placed between the moving seats 4. The two sets of guide rails are placed on the moving seats 4 at both ends respectively. When placing them, the splicing end of the elevator guide rail is attached to the limiting plate 18. On the 9th, the position is fixed by the limiting plate 19, and then the second drive motor 5 is controlled to work, so that the second drive motor 5 drives the clamping screw 6 to rotate. The clamping screw 6 cooperates with the clamping plates 7 at both ends to provide power, so that the clamping plates 7 at both ends move inward synchronously. Under the support of the adjusting screw 13, the pressure block 16 moves and comes into contact with the guide rail through the contact rubber block 17, thus fixing the guide rail. If the guide rail is not placed in the correct position, one side of the clamping plate 7 will contact the guide rail first, and then push the elevator guide rail to move towards the center. Then, through the pushing and pressing of the clamping plates 7 at both ends, the guide rail is aligned to the center, thus completing the fixing of the guide rail. In addition, the contact rubber block 17 improves the contact effect and enhances the anti-slip ability, making the fixing more stable.

[0050] During the splicing test, the limiting plate 19 is removed, and then the first drive motor 3 is controlled to operate, causing the first drive motor 3 to control the rotation of the drive screw 2. The drive screw 2 cooperates with the movable seats 4 at both ends. The movable seats 4 cooperate with the drive screw 2 through the support slider 20. Under the action of the support plate 21, the support slider contacts the support plate 21 through the movable pulley 24, receiving support from the support plate 21, thereby supporting the movable seat 4 and avoiding pressure on the drive screw 2. This allows the drive screw 2 to drive stably, enabling the support slider to move stably with the movable seat 4. Furthermore, the rotation of the movable pulley 24 reduces the friction of the simple contact structure, making the movement smoother. The sliding hole... 23 works in conjunction with guide rod 22. Under the guidance and constraint of guide rod 22, the support slider 20 is kept stable, which in turn drives the moving seat 4 to move stably, ensuring the stable movement of the moving seat 4. Under the power provided by drive screw 2, the moving seat 4 moves towards the center with the fixed guide rail, thereby splicing the guide rail. In addition, when splicing the guide rail, the support cylinder 10 is controlled to work, so that the support cylinder 10 drives the support block 11 to rise. The support block 11 cooperates with the contact plate 12 through the support roller 25 to provide thrust, lifting one end of the movable frame 9, so that the movable frame 9 rotates along the frame 1, thereby causing the support structure to deflect and change angle, providing different environments for guide rail splicing tests.

[0051] Of all the solutions mentioned above, those involving the connection between two components can be selected according to the actual situation, such as welding, bolt and nut connection, bolt or screw connection, or other known connection methods, which will not be elaborated here. For all the fixed connections mentioned above, welding is preferred. Although embodiments of this utility model have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principles and spirit of this utility model.
