Description

Technical Field

[0001] This utility model relates to the field of elevator counterweight technology, and in particular to an anti-deviation and vibration-damping elevator counterweight guide rail fixing mechanism. Background Technology

[0002] As a key component guiding the vertical movement of the counterweight device, the stability of the fixing mechanism of the elevator directly affects the elevator's operational safety and lifespan. This mechanism needs to precisely fix the guide rail to the shaft wall and withstand the radial impact force and axial lateral force generated by the high-speed movement of the counterweight. Therefore, it needs to have sufficient rigidity and limiting capacity. Its main structure includes a base, clamps, guide rail body, fastening bolts and other gaskets.

[0003] Existing counterweight guide rail fixing mechanisms mostly use a single-plate base with a U-shaped clamp structure, directly fastened with bolts. This type of device has obvious defects; it only fixes the relative position of the guide rail and the wall, and its limiting effect cannot extend to the guide rail itself. This causes high-frequency repetitive oscillations during operation, reducing the safety factor. To improve the above problems, existing technologies attempt to improve stability and reduce vibration by installing limiting blocks on both sides of the rail, based on the mounting base. However, in actual use, the shape and contour of the limiting blocks are fixed and cannot adapt to different specifications of rails, ultimately resulting in insufficient clamping force. After long-term use, the vibration problem still exists. Summary of the Invention

[0004] To overcome the above shortcomings, this utility model provides an anti-deviation and vibration-damping elevator counterweight guide rail fixing mechanism, which aims to improve the problem that the shape and contour of the limiting block in the existing technology cannot be fixed to different specifications of rails, resulting in insufficient clamping force and vibration problems that still exist after long-term use.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: an anti-deviation and vibration-damping elevator counterweight guide rail fixing mechanism, comprising a connecting base, wherein clamping components are installed on both the left and right sides of the top wall of the connecting base, the function of the clamping components being to maintain stability and reduce vibration; buffering components are installed on the top and bottom of the connecting base, the function of the buffering components being to absorb and further reduce vibration; the clamping components include two lower clamping blocks, the lower clamping blocks being slidably connected to the left and right sides of the top wall of the connecting base; an upper clamping block is fixedly connected to the top wall of the lower clamping blocks; push bolts are threadedly connected inside both lower clamping blocks; and multiple adapting components are equidistantly installed inside the upper clamping block.

[0006] As a further description of the above technical solution:

[0007] The adaptation component includes connecting cylinders, each of which is fixedly connected at equal intervals to the middle of the connecting cylinder. Each of the connecting cylinders has a sliding rod slidably connected to its inner wall, and each of the connecting cylinders has an adjusting rod threadedly connected to its inner wall. The adjusting rod is located at the end of the sliding rod.

[0008] As a further description of the above technical solution:

[0009] The buffer assembly includes a wave plate, which is fixedly connected to the bottom wall of the lower clamping block. Disc springs are fixedly connected to the four corners of the bottom wall of the connecting base, and compression assemblies are fixedly connected to the outer walls of the connecting base.

[0010] As a further description of the above technical solution:

[0011] The compression assembly includes multiple sleeves, each sleeve being fixedly connected to the outer wall of the connecting base. Each sleeve has a telescopic base slidably connected to its inner wall, and each telescopic base has a spring fixedly connected to its top. The spring is located inside the sleeve.

[0012] As a further description of the above technical solution:

[0013] Rubber pads are fixedly connected to the inner sides of both lower clamping blocks, and a track is installed in the middle of the top wall of the connecting base.

[0014] As a further description of the above technical solution:

[0015] Square protrusions are fixedly connected to the top walls of the left and right sides of the connecting base, and the two pushing bolts are threaded into the inside of the square protrusions.

[0016] As a further description of the above technical solution:

[0017] Each of the sliding rods has a slide rail fixedly connected to its outer wall, and the sliding rods are slidably connected to the inner wall of the connecting cylinder via the slide rail.

[0018] As a further description of the above technical solution:

[0019] The bottom ends of both lower clamping blocks are fixedly connected with reinforcing ribs, and the left and right sides of the connecting base are each threaded with two mounting bolts.

[0020] This utility model has the following beneficial effects:

[0021] 1. In this utility model, rotating the push bolt causes the two lower clamping blocks to move towards each other, carrying the upper clamping block, and clamping the bottom of the track. Rotating the adjusting rod on the upper clamping block pushes the sliding rod to slide inside the connecting cylinder, which can adapt to different specifications of tracks. This mechanism uses multiple independent limiting modules, which can change the spacing according to the track changes, solving the problems in the prior art where the shape and contour of the limiting block are fixed and cannot adapt to different specifications of tracks, resulting in insufficient clamping force and vibration after long-term use.

[0022] 2. In this utility model, the wave plate is located below the lower clamping block, which can filter and absorb high-frequency fine vibrations in the vertical direction. The disc spring can filter the vibration between the connecting base and the mounting wall, preventing the fasteners from loosening due to long-term vibration. The four compression components are installed at the four corners of the connecting base. Each telescopic base can slide independently in the sleeve to adapt to walls with different flatness. The spring can filter and absorb vibrations in the vertical direction of the connecting base, reducing structural vibration and noise. This mechanism solves the harm of fine vibrations to the structural integrity and improves the safety of track operation. Attached Figure Description

[0030] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0031] Reference Figure 1 , Figure 3 and Figure 4 The present invention provides an embodiment of an anti-deviation and vibration-damping elevator counterweight guide rail fixing mechanism, including a connecting base 1. Clamping components 2 are installed on both the left and right sides of the top wall of the connecting base 1. The function of the clamping components 2 is to maintain stability and reduce vibration. Buffer components 3 are installed on the top and bottom of the connecting base 1. The function of the buffer components 3 is to absorb and further reduce vibration.

[0032] The clamping assembly 2 includes two lower clamping blocks 201, which are slidably connected to the left and right sides of the top wall of the connecting base 1. An upper clamping block 202 is fixedly connected to the top wall of the lower clamping blocks 201. Pushing bolts 203 are threadedly connected inside the two lower clamping blocks 201. Multiple adaptation components 204 are installed at equal intervals inside the upper clamping block 202.

[0033] The adaptation component 204 includes a connecting cylinder 2041, which is fixedly connected at equal intervals to the middle of the connecting cylinder 2041. The inner walls of the multiple connecting cylinders 2041 are slidably connected with sliding rods 2042, and the inner walls of the multiple connecting cylinders 2041 are threadedly connected with adjusting rods 2043. The adjusting rods 2043 are located at the ends of the sliding rods 2042.

[0034] Rubber pads 4 are fixedly connected to the inner sides of the two lower clamping blocks 201. A rail 5 is installed in the middle of the top wall of the connecting base 1. Square protrusions 6 are fixedly connected to the top walls of the left and right sides of the connecting base 1. Two push bolts 203 are threaded into the inside of the square protrusions 6. A slide rail 8 is fixedly connected to the outer wall of the multiple sliding rods 2042. The multiple sliding rods 2042 are slidably connected to the inner wall of the connecting cylinder 2041 through the slide rail 8.

[0035] Specifically, the track 5 is placed in the middle region of the connecting base 1, within the space between two opposing lower clamping blocks 201 and the corresponding upper clamping block 202. Then, using a tool, the push bolts 203 located on both sides of the connecting base 1 are rotated. The threaded sections of the push bolts 203 engage with the threaded holes of the lower clamping blocks 201, causing the two lower clamping blocks 201 to begin moving in opposite directions, carrying the upper clamping blocks 202 mounted on them. Both move towards the middle position of the connecting base 1, clamping the bottom two sides of the track 5 through the inner surfaces of the lower clamping blocks 201. After the lower clamping blocks 201 on both sides are moved to the adjusted position where they fit against the bottom of the track 5, the adjusting rod 2043 on the upper clamping block 202 is rotated with a tool. As the adjusting rod 2043 rotates around its own axis, its end will push the sliding rod 2042 to slide axially inside the connecting cylinder 2041. Depending on the width of different models of track 5, the amount of adjustment required for the adjusting rod 2043 to rotate will also be different. Thus, by changing the extension length of the sliding rod 2042, the top clamping requirements of different specifications of track 5 can be adapted.

[0036] Reference Figure 2 and Figure 5 The buffer assembly 3 includes a wave plate 301, which is fixedly connected to the bottom wall of the lower clamping block 201. Disc springs 302 are fixedly connected to the four corners of the bottom wall of the connecting base 1, and compression assemblies 303 are fixedly connected to the outer walls of the connecting base 1.

[0037] The compression assembly 303 includes multiple sleeves 3031, which are all fixedly connected to the outer wall of the connecting base 1. The inner walls of the multiple sleeves 3031 are slidably connected to telescopic bases 3033, and the top of the multiple telescopic bases 3033 are all fixedly connected to springs 3032, which are disposed inside the sleeves 3031.

[0038] Specifically, the upper surface of the corrugated plate 301 is attached to the bottom of the lower clamping block 201 and located below the lower clamping block 201. Its corrugated structure can filter and absorb high-frequency micro-vibrations transmitted in the vertical direction through its own deformation. The disc spring 302 is installed in the gap between the connecting base 1 and the mounting wall to filter the vibration transmitted between the connecting base 1 and the mounting wall. It can offset the vibration energy through elastic expansion and contraction to prevent the fastener from loosening due to long-term vibration. The four compression components 303 are respectively installed at the four corner positions of the connecting base 1. The rod part of the telescopic base 3033 in each compression component 303 can slide independently along the axis inside the sleeve 3031. By adjusting the amount of expansion and contraction, it can adapt to the wall surface with different flatness. At the same time, the spring 3032 inside the sleeve 3031 abuts against the telescopic base 3033 to filter and absorb vibrations in the direction perpendicular to the surface of the connecting base 1. The expansion and contraction deformation of the spring 3032 reduces the overall vibration of the structure and the noise generated during operation.

[0039] Reference Figure 1 and Figure 2 The bottom ends of the two lower clamping blocks 201 are fixedly connected with reinforcing ribs 9, and the left and right sides of the connecting base 1 are threaded with two mounting bolts 7.

[0040] Specifically, the reinforcing rib 9 enhances the connection rigidity and torsional resistance between the lower clamping block 201 and the upper clamping block 202, and the mounting bolt 7 fixes the connecting base 1 to the mounting wall.

[0041] Working principle: The track 5 is placed in the middle of the connecting base 1, between the two lower clamping blocks 201 and the upper clamping block 202. At this time, the push bolt 203 is rotated, and the two lower clamping blocks 201 begin to carry the upper clamping block 202 and move towards each other, moving towards the middle of the connecting base 1 to clamp the bottom of the track 5. After the lower clamping blocks 201 on both sides are adjusted to the correct position, the adjusting rod 2043 on the upper clamping block 202 is rotated. As the adjusting rod 2043 rotates, it pushes the sliding rod 2042 to slide inside the connecting cylinder 2041. The adjustment amount of the adjusting rod 2043 is different according to the width of different tracks 5, so it can adapt to different specifications of tracks 5. This mechanism uses multiple independent limiting modules, which can change the spacing according to the changes of the track 5. This solves the problem that the shape and contour of the limiting block are fixed in the existing technology, which cannot adapt to different specifications of tracks 5, and ultimately leads to insufficient clamping force and vibration problem after long-term use.

[0042] The wave plate 301 is located below the lower clamping block 201 and can filter and absorb high-frequency fine vibrations in the vertical direction. The disc spring 302 can filter the vibration between the connecting base 1 and the front wall surface, preventing the fasteners from loosening due to long-term vibration. Four compression components 303 are installed at the four corners of the connecting base 1. Each telescopic base 3033 can slide independently in the sleeve 3031 to adapt to different flatness of the front. At the same time, the spring 3032 can filter and absorb vibrations in the vertical direction of the connecting base 1, reducing structural vibration and noise. This mechanism focuses on solving the harm of fine vibrations to the structural integrity and improves the safety of the track 5 during operation.

[0043] Finally, it should be noted that the above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
