[0002] Against the backdrop of rapid development in urban infrastructure construction, prefabricated cable equipment wells are widely used in the laying and maintenance of power, communication and other cable systems due to their advantages such as high construction efficiency and stable quality. However, the precision and applicability of height adjustment during installation and use have always been key challenges in engineering practice.

[0003] Currently, most precast cable equipment wells rely on on-site pouring of concrete foundations or adding / removing brickwork to adjust their height. This process is cumbersome, has a long construction period, and low adjustment accuracy, making it difficult to adapt to complex terrain and the needs of precast cable equipment wells of different specifications. If the ground elevation changes later, secondary adjustments cannot be made, which can easily lead to uneven connection between the precast cable equipment well and the ground, causing safety hazards or affecting cable maintenance operations. Furthermore, some existing adjustment devices have poor versatility and can only be adapted to specific types or sizes of precast cable equipment wells. When dealing with precast cable equipment wells of multiple specifications, adjustment components need to be frequently replaced, increasing project costs and construction complexity.

[0004] Therefore, a height adjustment device for wells of prefabricated cable equipment applicable to multiple types is proposed. Utility Model Content

[0005] The purpose of this utility model is to provide a height adjustment device applicable to various types of precast cable equipment wells.

This process is cumbersome, has a long construction period, and low adjustment accuracy, making it difficult to adapt to complex terrain and the needs of precast cable equipment wells of different specifications. Furthermore, if the ground elevation changes subsequently, secondary adjustments cannot be made, which can easily lead to unevenness between the precast cable equipment well and the ground, causing safety hazards or affecting cable maintenance operations. In addition, some existing adjustment devices have poor versatility, only adapting to specific types or sizes of precast cable equipment wells. When dealing with precast cable equipment wells of multiple specifications, frequent replacement of adjustment components is required, increasing project costs and construction complexity.

[0026] 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.

[0027] Please see Figure 1-7 The present invention provides the following technical solution:

[0028] A height adjustment device applicable to multi-category prefabricated cable equipment wells includes a base plate 1, a hydraulic jack 4 placed on the top of the base plate 1, an adjustment mechanism 3 set on the top of the base plate 1, a support mechanism 2 set on the top of the base plate 1, and several support mechanisms 2. Guide columns 9 are fixedly connected to the front and rear sides of the top of the base plate 1.

[0029] The adjustment mechanism 3 includes a support plate 301, several adjustment cylinders 302, several adjustment columns 303, and several anti-slip teeth 304. The side of the adjustment cylinder 302 closest to the support plate 301 is fixedly connected to the support plate 301. The side of the adjustment column 303 closest to the adjustment cylinder 302 extends into the interior of the adjustment cylinder 302 and makes movable contact with the interior of the adjustment cylinder 302. The bottom of the anti-slip teeth 304 is fixedly connected to the top of the adjustment column 303.

[0030] In this embodiment: The base plate 1 is hoisted to the bottom of the pit via an external hoisting device connected to the lifting ring 5, and fixed by external bolts passing through the connecting hole 6. Based on the diameter of the precast cable equipment well, the adjusting column 303 is pulled out from the adjusting cylinder 302 to a suitable length. The precast cable equipment well is then hoisted to the top of the support plate 301 using the external hoisting device, so that the anti-slip teeth 304 contact the bottom of the precast cable equipment well. The support plate 301, adjusting cylinder 302, and anti-slip teeth 304 jointly support the precast cable equipment well. An external rod-shaped tool is used to lift the hydraulic jack 4 placed on top of the base plate 1. The guide cylinder 8 slides along the guide column 9 to achieve stable guidance. The lifting height is accurately determined through the scale groove 10, thus determining the lifting adjustment height of the precast cable equipment well. After adjustment, the hexagonal fixing ring 201 is rotated to drive the support rod 202 into the limiting cylinder, making its bottom tightly contact the base plate 1, forming... After the stable support structure is established, the hydraulic jack 4 is removed. If the equipment well needs to be raised due to subsequent settlement, the hydraulic jack 4 is repositioned and the limit ring 11 is engaged, allowing for further height adjustment. This achieves stable support and precise adjustment for precast cable equipment wells of various specifications, solving the problem that many existing precast cable equipment wells rely on on-site pouring of concrete foundations or adding / removing brickwork to adjust their height. This process is cumbersome, has a long construction period, and low adjustment accuracy, making it difficult to adapt to complex terrain and the needs of precast cable equipment wells of different specifications. If the ground elevation changes later, it is impossible to make secondary adjustments, which can easily lead to uneven connection between the precast cable equipment well and the ground, causing safety hazards or affecting cable maintenance operations. Furthermore, some existing adjustment devices have poor versatility and can only be adapted to specific types or sizes of precast cable equipment wells. When dealing with precast cable equipment wells of various specifications, it is necessary to frequently replace adjustment components, increasing project costs and construction complexity.

[0031] Specifically, such as Figure 4As shown, the support mechanism 2 includes a hexagonal fixing ring 201, a support rod 202, and a support cylinder 203. The hexagonal fixing ring 201 is fixedly sleeved on the surface of the support rod 202. The top of the support rod 202 extends into the interior of the support cylinder 203 and is threadedly connected to the interior of the support cylinder 203. The top of the support cylinder 203 is fixedly connected to the bottom of the adjusting cylinder 302.

[0032] Specifically, such as Figure 1 , Figure 4 and Figure 7 As shown, a limiting sleeve 7 is fixedly connected to the top of the base plate 1 to cooperate with the support rod 202, and the support rod 202 is movably inserted into the inside of the limiting sleeve 7.

[0033] Specifically, such as Figure 7 As shown, a chamfer 12 is provided at the top of the inner wall of the limiting sleeve 7.

[0034] In this embodiment: In the support mechanism 2, the hexagonal fixing ring 201 facilitates the rotation of the support rod 202 with the help of an external wrench. The threaded connection between the support rod 202 and the support cylinder 203 can be adjusted by rotation. The support rod 202 is moved and adjusted until it is inserted into the limiting sleeve 7, so that the bottom of the support rod 202 contacts the top of the base plate 1. Together with the support cylinder 203, it forms a stable support for the adjusting cylinder 302. The limiting sleeve 7 plays a limiting and guiding role on the bottom of the support rod 202 to prevent it from tilting or shifting. The chamfer 12 on the top of the inner wall of the limiting sleeve 7 reduces the difficulty of inserting the support rod 202 into the limiting sleeve 7 and improves the ease of operation.

[0035] Specifically, such as Figure 1 , Figure 2 and Figure 6 As shown, a limit ring 11 is fixedly connected to the bottom of the support plate 301, and the surface of the telescopic end of the hydraulic jack 4 is in contact with the inner wall of the limit ring 11.

[0036] Specifically, such as Figure 1 , Figure 2 and Figure 5 As shown, a guide cylinder 8 is movably sleeved on the surface of the guide column 9, and the top of the guide cylinder 8 is fixedly connected to the bottom of the support plate 301.

[0037] In this embodiment: the limiting ring 11 can accurately position the telescopic end of the hydraulic jack 4, ensuring that the lifting force acts stably on the center of the support plate 301 and avoid force deviation. The sliding cooperation between the guide cylinder 8 and the guide column 9 provides guiding constraints for the lifting and lowering of the support plate 301, effectively preventing the support plate 301 from shaking or deviating during the adjustment process and ensuring adjustment stability.

[0038] Specifically, such as Figure 2 and Figure 5As shown, a scale groove 10 is provided on the left side of the guide post 9. The number of scale grooves 10 is several and they are evenly distributed on the left side of the guide post 9.

[0039] Specifically, such as Figure 1 As shown, the top of the base plate 1 is provided with a number of connecting holes 6, which are evenly distributed on the top of the base plate 1. The top of the base plate 1 is fixedly connected with three lifting rings 5, which are evenly distributed on the top of the base plate 1.

[0040] In this embodiment: the scale groove 10 can intuitively reflect the lifting height of the support plate 301, providing a reference for precise adjustment and improving the height control accuracy; the connecting hole 6 facilitates fixing the base plate 1 to the pre-cast base at the bottom of the pit with bolts, ensuring the stability of the base plate 1; and the lifting ring 5 facilitates moving the base plate 1 with the help of external hoisting equipment, simplifying the installation and handling process.

[0041] Working principle: By connecting the external hoisting equipment to the lifting ring 5, the base plate 1 is hoisted to the top of the pre-cast foundation at the bottom of the pit. Then, external bolts are passed through the connecting holes 6 at the top of the base plate 1 to fix the base plate 1 to the foundation at the bottom of the pit, thus achieving foundation fixation of the base plate 1. At this time, according to the diameter of the precast cable equipment well, the adjusting column 303 is pulled out from the adjusting cylinder 302 to the required length to adapt to precast cable equipment wells of different diameters. Then, the external hoisting equipment is used to hoist the precast cable equipment well to the top of the support plate 301, so that the bottom of the precast cable equipment well contacts the top of the anti-slip teeth 304. The anti-slip teeth 304 can increase the friction with the bottom of the precast cable equipment well to prevent slippage. The support plate 301 and the adjusting cylinder 302 cooperate with the adjusting column 303 to achieve foundation fixation. The anti-slip teeth 304 on the top of the precast cable equipment well jointly support the well. The guide column 9 on the top of the base plate 1 plays a guiding role in the subsequent adjustment process. At this time, the hydraulic jack 4 placed on the top of the base plate 1 is lifted by the external rod-shaped tool. The telescopic end of the hydraulic jack 4 pushes the support plate 301 upward. The guide cylinder 8 fixed at the bottom of the support plate 301 slides along the surface of the guide column 9. The cooperation of the guide column 9 and the guide cylinder 8 stabilizes and guides the movement of the support plate 301, preventing the support plate 301 from deviating during the lifting process. The scale grooves 10 opened on the left side of the guide column 9 are evenly distributed. By observing the position of the guide cylinder 8 corresponding to the scale groove 10, the lifting height can be accurately judged, which facilitates the precise height adjustment of the precast cable equipment well. After adjustment, use an external wrench to rotate the hexagonal retaining ring 201. The hexagonal retaining ring 201 drives the support rod 202 to rotate. Since the support rod 202 is internally threaded with the support cylinder 203, its bottom gradually extends into the limiting sleeve 7 during rotation. The chamfer 12 at the top of the inner wall of the limiting sleeve 7 facilitates the smooth insertion of the support rod 202 until the bottom of the support rod 202 is in close contact with the top of the base plate 1. At this time, the support rod 202 and the support cylinder 203 form a stable support structure, which strengthens the support of the adjusting cylinder 302, making the placement of the precast cable equipment well more stable. Then, pull the hydraulic jack 4 to disengage the surface of its telescopic end from the limiting ring 11 fixed at the bottom of the support plate 301, thereby removing the hydraulic jack 4. When the precast cable equipment well needs to be raised due to settlement issues, the hydraulic jack 4 is placed back on top of the base plate 1 and pushed until its telescopic end engages with the limit ring 11. The height of the support plate 301 and the precast cable equipment well on top of the support plate 301 can then be adjusted again using the hydraulic jack 4. This achieves stable support and precise height adjustment for various types of precast cable equipment wells. It solves the problem that many existing precast cable equipment wells rely on on-site pouring of concrete foundations or adding / removing brickwork to adjust their height. This process is cumbersome, has a long construction period, and low adjustment accuracy, making it difficult to adapt to complex terrain and the needs of precast cable equipment wells of different specifications. Furthermore, if the ground elevation changes subsequently, secondary adjustments are impossible, easily leading to uneven contact between the precast cable equipment well and the ground.This can pose safety hazards or affect cable maintenance operations. Furthermore, some existing adjusting devices have poor versatility, only adapting to specific types or sizes of prefabricated cable wells. When dealing with multi-specification prefabricated cable wells, frequent replacement of adjusting components is required, increasing project costs and construction complexity. It should be noted that the hydraulic jack 4 is a mature, publicly available technology; its basic mechanism and usage will not be elaborated upon here.

[0042] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
