Description

Technical Field

[0001] This utility model relates to the field of municipal sanitation technology, and in particular to a buffer base for elevator installation. Background Technology

[0002] Current elevators are equipped with fall protection systems, but they are not foolproof. In order to protect people's lives in the event of an accident, it is urgent to install an efficient buffer device at the bottom of the elevator shaft.

[0003] However, in practical use, the existing buffers still have the following technical problems: Regarding compatibility, their mounting holes are mostly fixed designs, requiring a perfect match with the positioning slots of the supporting columns. If the buffer model is updated or the supporting column hole spacing changes, new holes need to be drilled in the supporting columns or base. Re-drilling not only consumes a lot of time but may also damage the structural integrity of the supporting columns, leading to a decrease in their load-bearing capacity and even safety hazards. In terms of buffering performance, existing products mostly rely on a single buffer element (such as a spring or rubber pad), concentrating the impact force on a single component. This makes the component prone to rapid aging due to overload, and there is a lack of effective force dispersion structures. Regarding maintenance, existing bases are mostly integrated structures. If the buffer element's performance deteriorates due to humidity, wear, etc., the entire base needs to be disassembled and replaced, which is complex and time-consuming. Some products have buffer elements welded to the base, making individual replacement impossible and requiring complete scrapping, resulting in high maintenance costs. Furthermore, due to the lack of modular design, it is difficult to quickly determine the condition of internal components during routine inspections. This may lead to buffer failure due to undetected potential problems, posing safety risks to elevator operation.

[0004] In response to this technical problem, this application proposes a buffer base for elevator installation. Utility Model Content

[0005] The purpose of this utility model is to solve the problems of poor adaptability, the need to re-drill holes for fixing positions, which affects efficiency and damages the structure; the reliance on a single component for buffering, which results in insufficient force distribution and easy displacement; and the difficulty in replacing individual components in an integrated design, which leads to high maintenance costs. Therefore, this utility model proposes a buffer base for elevator installation.

[0006] To achieve the above objectives, the present invention provides the following technical solution: An elevator installation buffer base includes a supporting column, a mounting base at the top of the supporting column, a hydraulic rod fixedly connected to the middle of the top side of the mounting base, a support seat fixedly connected to the bottom outer side of the hydraulic rod, an abutment block fixedly connected to the top of the hydraulic rod, a spring fixedly connected to the bottom side of the abutment block, the bottom end of the spring fixedly connected to the top side of the support seat, and the spring sleeved on the top outer side of the hydraulic rod. The mounting base has four pre-reserved sliding grooves at its top corners, a through groove on the bottom side of the inner wall of each pre-reserved sliding groove, a sleeve slidably connected to the inner wall of the through groove, a limiting ring with a size matching the pre-reserved sliding groove fixedly connected to the top of the sleeve, and an anchor bolt threadedly connected to the inner wall of the sleeve.

[0007] Furthermore, an installation groove is provided on the top side of the abutment block, and a lower steel plate is detachably connected to the inner wall of the installation groove. A honeycomb core board is fixedly connected to the top of the lower steel plate, and an upper steel plate is fixedly connected to the top of the honeycomb core board. A buffer is connected to the top of the upper steel plate through a fixing component.

[0008] Furthermore, one side of the outer wall of the abutment block is connected to the support seat through a limiting component.

[0009] Furthermore, each of the four corners of the top of the supporting column is provided with a positioning groove that is compatible with the sleeve, and the outer side of the anchor bolt passes through the sleeve and is threadedly connected to the inner wall of the positioning groove.

[0010] Furthermore, the limiting component includes a fixing plate, which is fixedly connected to one side of the outer wall of the abutment block. A limiting plate is threadedly connected to the top side of the fixing plate, and a guide plate is slidably connected to the bottom end of the limiting plate. One end of the guide plate is fixedly connected to the outer wall of the support base.

[0011] Furthermore, a buffer pad is fixedly connected to the bottom of the lower steel plate, the bottom of the buffer pad is in contact with the bottom side of the inner wall of the mounting groove, and an anti-slip washer is fixedly connected to the bottom side of the limiting ring.

[0012] Furthermore, the fixing component includes a base plate, which is fixedly connected to the bottom of the buffer component. Fixing bolts are provided at all four corners of the base plate, and the bottom ends of the fixing bolts are threadedly connected to the upper steel plate.

[0013] This utility model has the following beneficial effects: 1. In this utility model, the pre-reserved sliding grooves at the four corners of the top of the mounting base cooperate with the sliding sleeve, so that the sleeve can flexibly adjust its position according to the different hole spacing of the positioning groove at the top of the support column, and then be fixed by anchor bolts. Installation can be completed without re-drilling holes on the support column, which solves the problem of low installation efficiency caused by re-drilling holes due to the change of buffer size in existing products.

[0014] 2. In this utility model, when the elevator car is impacted, the buffer first absorbs part of the impact force, and the honeycomb core plate disperses the remaining impact force through the honeycomb structure. In conjunction with the buffer pad at the bottom of the lower steel plate, the vibration is further attenuated. At the same time, the damping effect of the hydraulic rod and the elastic restoring force of the spring form a secondary buffer. Compared with the existing single buffer structure base, the overall buffering effect is more stable. Moreover, the modular design allows the buffer and honeycomb core plate to be disassembled and replaced separately, avoiding the cumbersome disassembly required for maintenance of existing products. This significantly reduces maintenance costs while ensuring the reliability of the buffer during long-term use. Attached Figure Description

[0017] 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.

[0018] Reference Figures 1-3An embodiment of this utility model provides: a buffer base for elevator installation, including a supporting column 1, an installation base 2 at the top of the supporting column 1, a hydraulic rod 3 fixedly connected to the middle of the top side of the installation base 2, a support seat 4 fixedly connected to the bottom of the outer side of the hydraulic rod 3, an abutment block 5 fixedly connected to the top of the hydraulic rod 3, a spring 6 fixedly connected to the bottom side of the abutment block 5, the bottom end of the spring 6 fixedly connected to the top side of the support seat 4, and the spring 6 sleeved on the top of the outer side of the hydraulic rod 3. The four corners of the top of the installation base 2 are provided with reserved sliding grooves 10, the bottom side of the inner wall of the reserved sliding grooves 10 is provided with through grooves 11, a sleeve 12 is slidably connected to the inner wall of the through grooves 11, a limiting ring 13 adapted to the size of the reserved sliding grooves 10 is fixedly connected to the top of the sleeve 12, and an anchor bolt 15 is threadedly connected to the inner wall of the sleeve 12. Specifically, when installing and fixing with the support column 1, the sleeve 12 can slide obliquely along the through groove 11 by utilizing the reserved sliding groove 10 at the four corners of the top of the mounting base 2. This allows the position to be adjusted according to the actual hole spacing of the positioning groove at the top of the support column 1. After sliding into place, the sleeve 12 is inserted into the positioning groove. The mounting base 2 and the support column 1 are firmly connected by tightening the anchor bolt 15. At this time, the limiting ring 13, together with the anti-slip washer 14 on its bottom side, tightly abuts against the top side of the reserved sliding groove 10, effectively preventing the sleeve 12 from sliding and enhancing the connection stability. This solves the problem of low installation efficiency caused by the need to re-drill holes in the support column 1 due to product size changes. The oblique sliding groove design enables flexible adaptation to support columns 1 or buffers with different hole spacings. Reference Figures 1-3 The abutment block 5 has an installation groove 16 on its top side. A lower steel plate 17 is detachably connected to the inner wall of the installation groove 16. A honeycomb core plate 18 is fixedly connected to the top of the lower steel plate 17. An upper steel plate 19 is fixedly connected to the top of the honeycomb core plate 18. A buffer member 22 is connected to the top of the upper steel plate 19 through a fixing component. One side of the outer wall of the abutment block 5 is connected to the support base 4 through a limiting component. The four corners of the top of the support column 1 are provided with positioning grooves that are adapted to the sleeve 12. The outer side of the anchor bolt 15 passes through the sleeve 12 and is threadedly connected to the inner wall of the positioning groove. The limiting component includes a fixing plate 7, which is fixedly connected to... On one side of the outer wall of the abutment block 5, the top side of the fixing plate 7 is threadedly connected to the limiting plate 8, and the bottom end of the limiting plate 8 is slidably connected to the guide plate 9. One end of the guide plate 9 is fixedly connected to the outer wall of the support base 4. The bottom of the lower steel plate 17 is fixedly connected to the buffer pad 23, and the bottom of the buffer pad 23 is in contact with the bottom side of the inner wall of the mounting groove 16. The bottom side of the limiting ring 13 is fixedly connected to the anti-slip washer 14. The fixing assembly includes a base plate 21, which is fixedly connected to the bottom of the buffer 22. Fixing bolts 20 are passed through the four corners of the base plate 21, and the bottom ends of the fixing bolts 20 are threadedly connected to the upper steel plate 19. Specifically, during the buffering operation, when the elevator car falls and collides with the impact block, the impact force is sequentially transmitted to the polyester-based buffer component 22, the upper steel plate 19, the honeycomb core panel 18, and the lower steel plate 17. The honeycomb core panel 18 disperses the impact force using its honeycomb structure, and the buffer pad 23 at the bottom of the lower steel plate 17 further absorbs the vibration. At the same time, the abutment block 5 is pressed down, causing the hydraulic rod 3 to contract and compress the spring 6. The elastic restoring force of the spring 6 and the damping effect of the hydraulic rod 3 together form a buffer. In the limiting assembly, when the fixing plate 7 moves down with the abutment block 5, the limiting plate 8 slides along the guide plate 9 to ensure that the abutment block 5 moves vertically. To avoid displacement, the synergistic effect of multiple structures achieves a buffering effect superior to that of existing single buffer components. When the buffering effect of the buffer component 22 deteriorates due to the air humidity in the stairwell or long-term use, the base plate 21 and the upper steel plate 19 can be separated by removing the fixing bolts 20, allowing the buffer component 22 to be replaced individually. If the honeycomb core panel 18 needs maintenance, the lower steel plate 17 can be removed from the mounting groove 16. The modular design eliminates the need to replace the entire base, effectively reducing maintenance costs and ensuring that the buffering effect is always reliable. The overall structure achieves the beneficial effects of strong adaptability, efficient installation, stable buffering, and convenient maintenance through mechanical cooperation.

[0019] Working principle: When using this buffer, the first step is to install and fix it: Place the mounting base 2 on top of the support column 1. According to the actual hole spacing of the positioning groove on the support column 1, push the sleeve 12 to slide obliquely along the reserved sliding grooves 10 at the four corners of the mounting base 2, so that the bottom end of the sleeve 12 is aligned with the positioning groove and inserted. At this time, the limiting ring 13 is stuck in the reserved sliding groove 10 to prevent the sleeve 12 from falling off. Tighten the anchor bolt 15 in the sleeve 12. The anchor bolt 15 passes through the sleeve 12 and is threadedly connected to the positioning groove. At the same time, the anti-slip washer 14 on the bottom side of the limiting ring 13 is tightly abutted against the top side of the through groove 11, so as to achieve a firm fixation between the mounting base 2 and the support column 1. Different hole spacings can be adapted without re-drilling. When installing the buffer assembly, embed the lower steel plate 17 into the mounting groove 16 of the abutment block 5. The buffer pad 23 at its bottom is in contact with the bottom of the groove. Then, fix the bottom plate 21 of the buffer component 22 to the upper steel plate 19 with the fixing bolts 20 to complete the overall assembly. When the elevator car falls and impacts the buffer 22, the impact force is initially absorbed by the buffer 22, then transmitted to the upper steel plate 19, dispersed by the honeycomb core panel 18, and then conducted to the lower steel plate 17. The buffer pad 23 further buffers the vibration. At the same time, the abutment block 5 moves downward under force, causing the hydraulic rod 3 to contract. The spring 6 on its outer side is compressed, generating elastic restoring force, which, together with the damping effect of the hydraulic rod 3, forms a secondary buffer. During this process, the fixing plate 7 on the outer wall of the abutment block 5 moves downward, causing the limiting plate 8 to slide vertically along the guide plate 9 on the support base 4, preventing the abutment block 5 from shifting and affecting the buffering effect. When the performance of the buffer 22 is affected by aging or humidity, it can be replaced individually by unscrewing the fixing bolt 20. If the honeycomb core panel 18 is damaged, the lower steel plate 17 can be removed from the mounting slot 16 for maintenance without disassembling the entire base, significantly improving maintenance efficiency.

[0020] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is 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.
