Description

Technical Field

[0001] This utility model relates to the field of steel collar compensation and reinforcement technology, specifically a multi-directional displacement compensation and self-adjusting reinforcement device for steel collars. Background Technology

[0002] In modern underground engineering and municipal construction, rectangular pipe jacking rings are widely used as an important component of pipeline construction for the laying and repair of underground pipelines. Due to the complex construction environment and frequent transportation, handling, and installation during construction, rectangular pipe jacking rings often face problems such as deformation and cracking during processing, transportation, and installation. This not only affects the service life and structural stability of the rings but may also lead to overall quality problems in the pipeline system.

[0003] The manufacturing of rectangular jacking pipe collars typically involves multiple processes such as welding, cutting, and bending. During processing, thermal stress, stress introduced during machining, and localized temperature changes during welding can lead to deformation or cracking of the collar. Especially in the welding process, temperature variations at the weld seam often cause localized stress concentration in the collar, resulting in material expansion and contraction, and consequently, changes in its overall shape. During transportation, rectangular jacking pipe collars, due to their large weight and volume, often require the use of heavy equipment for handling. During transport, they are inevitably affected by uneven ground and traffic vibrations, and the collar may deform or crack due to excessive impact. Impacts, particularly on welded areas or joints, can easily cause weld fractures at the joints, leading to material failure.

[0004] During installation, the pipe jacking collar typically needs to withstand significant external pressure and environmental stress. Whether installed underground or in open-air conditions, factors such as ambient temperature, soil pressure, and the operation of construction equipment can all affect the collar. Improper installation or an inadequately designed support system can lead to collar deformation or even cracking. Furthermore, if the collar is not fully aligned or experiences uneven stress during installation, stress concentration can occur, resulting in deformation and cracking.

[0005] In underground engineering, the construction environment is complex and uncontrollable. Changes in geological conditions (such as groundwater level and soil pressure) and other unexpected situations that may occur during construction (such as equipment failure and material defects) can all lead to excessive stress or localized damage to the rectangular jacking pipe collar. Furthermore, moisture and corrosive substances in the underground environment can negatively impact the long-term durability of the steel collar, especially during transportation and installation. Without proper protection, the collar is susceptible to corrosion from the external environment, leading to deformation or cracking. No solutions have yet been proposed for these technical problems. Summary of the Invention

[0006] To address the problems in related technologies, this utility model proposes a multi-directional displacement compensation self-adjusting reinforcement device for steel sleeve rings to overcome the aforementioned technical problems existing in the prior art. The purpose of this utility model is to compensate for the stress concentration of the original connection part by connecting the steel sleeve and the steel sleeve ring, thereby enhancing its load-bearing capacity, preventing deformation or cracking during construction or use, improving the stability and safety of the structure, and better coping with external pressure, temperature changes, and environmental corrosion that may occur during long-term use. This extends the service life, reduces maintenance and replacement costs, avoids installation errors caused by deformation or damage, ensures accuracy during construction, and reduces additional work and repair costs caused by inaccurate installation. At the same time, through welding compensation and reinforcement, the connection part of the steel sleeve ring gains stronger load-bearing and fatigue resistance, which reduces the failure rate during long-term use and ensures the long-term stable operation of the overall pipeline system.

[0007] To achieve the above objectives, this utility model provides the following technical solution: a multi-directional displacement compensation self-adjusting reinforcement device for a steel sleeve, comprising a steel sleeve, on which a steel sleeve is provided, and a plurality of slots are formed on the outer surface of the steel sleeve, and a retaining plate is installed inside the slots;

[0008] The inner surface of the steel collar is provided with several placement grooves. A movable plate is provided inside the placement groove. The movable plate is connected to the placement groove by a spring. An opening is provided at the bottom of the movable plate. A support column is fixedly installed inside the opening. A left movable plate and a right movable plate are respectively fitted on the support column. Rollers are movably connected to the ends of the left and right movable plates away from the support column. The left and right movable plates are connected to the movable plate by a spring.

[0009] Preferably, the interior of the placement groove is further provided with a rubber column, the two ends of which are fixedly connected to the movable plate and the placement groove respectively, and a spring is fitted on the outer surface of the rubber column. Several rubber columns and springs are provided.

[0010] Preferably, sliding grooves are provided on both inner walls of the placement groove, and sliding blocks that match the sliding grooves are fixedly connected to both ends of the moving plate.

[0011] Preferably, the top end of the card plate is arranged in a decreasing manner from bottom to top, and both ends of the card plate are provided with a snap-fit ​​part.

[0015] Compared with the prior art, the beneficial effects of this utility model are:

[0016] (1) This utility model is a multi-directional displacement compensation self-adjusting reinforcement device for steel collar. By setting a card plate, a movable plate, a spring one, a support column, a left movable plate, a right movable plate, a roller and a spring two, the steel sleeve and steel collar are initially connected. The stress concentration of the original connection part is compensated by welding, which enhances its load-bearing capacity and effectively prevents deformation or cracking during construction or use. This improves the stability and safety of the structure. The steel collar after compensation and reinforcement can better cope with external pressure, temperature changes and environmental corrosion that may occur during long-term use, extending its service life and reducing maintenance and replacement costs. After welding and reinforcement, the stress distribution in the welding area of ​​the steel collar is optimized, avoiding local stress concentration, making the overall structure more uniform and stable when bearing external loads, and improving mechanical performance.

The steel sleeve and steel sleeve ring are connected by welding, which effectively improves the stability of the installation, avoids installation errors caused by deformation or damage, ensures the accuracy in the construction process, and reduces the extra work and repair costs caused by inaccurate installation. Through welding compensation and reinforcement, the connection part of the steel sleeve ring has stronger load-bearing and fatigue resistance, which reduces the failure rate in long-term use and ensures the long-term stable operation of the overall pipeline system.

[0023] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0024] Example

[0025] Please see Figure 1-4 This utility model proposes a technical solution for a multi-directional displacement compensation self-adjusting reinforcement device for steel collars: a multi-directional displacement compensation self-adjusting reinforcement device for steel collars includes a steel sleeve 1, a steel collar 2 is provided on the steel sleeve 1, and a plurality of slots 3 are opened on the outer surface of the steel sleeve 1, and a retaining plate 4 is installed inside the slots 3; specifically, both the steel sleeve 1 and the steel collar 2 are rectangular in structure, and the retaining plate 4 is made of metal material;

[0026] The inner surface of the steel collar 2 has several placement grooves 5. A movable plate 6 is installed inside the placement groove 5. The movable plate 6 is connected to the placement groove 5 by a spring 7. The bottom of the movable plate 6 has an opening, and a support column 8 is fixedly installed inside the opening. A left movable plate 9 and a right movable plate 10 are respectively fitted on the support column 8. Rollers 11 are movably connected to the ends of the left movable plate 9 and the right movable plate 10 away from the support column 8. The left movable plate 9 and the right movable plate 10 are both connected to the movable plate 6 by a spring 12. Specifically, when the steel collar 2 is installed on the steel sleeve 1, the steel collar 2 is first fitted onto the steel sleeve 1. When the placement groove 5 on the steel collar 2 moves to the same horizontal line as the placement groove, under the action of the spring 7, the movable plate 6 drives the left movable plate 9 and the right movable plate 10 to move downward. Under the action of the spring 12, the left movable plate 9 and the right movable plate 10 are respectively locked on the locking plate 4, thereby connecting the steel sleeve 1 and the steel collar 2.

[0027] Please see Figure 1-2 As shown, furthermore, a rubber column 13 is provided inside the placement groove 5. The two ends of the rubber column 13 are fixedly connected to the moving plate 6 and the placement groove 5 respectively. A spring 7 is sleeved on the outer surface of the rubber column 13. Several rubber columns 13 and springs 7 are provided.

[0028] In this embodiment, the rubber column 13 effectively improves the stability of the connection between the steel sleeve 1 and the steel collar 2.

[0029] Please see Figure 1-2 As shown, furthermore, sliding grooves are provided on both sides of the inner wall of the placement groove 5, and sliding blocks 14 that match the sliding grooves are fixedly connected to both ends of the moving plate 6.

[0030] In this embodiment, the moving plate 6 drives the sliding block 14 to move within the sliding groove when it moves, thereby improving the stability of the moving plate 6.

[0031] Please see Figure 1-2 As shown, the top end of the card plate 4 is arranged in a decreasing manner from bottom to top, and both ends of the card plate 4 are provided with a snap-fit ​​part 15.

[0032] Please see Figure 3 As shown, both the left movable plate 9 and the right movable plate 10 are arranged in a V-shape.

[0033] Please see Figure 1 As shown, both the steel sleeve 1 and the steel ring 2 are rectangular in shape.

[0034] Furthermore, the steel sleeve 1 and the steel collar 2 are connected by welding.

[0035] The working principle of this utility model:

[0036] When installing the steel collar 2 onto the steel sleeve 1, the steel collar 2 is first placed on the steel sleeve 1. When the placement groove 5 on the steel collar 2 moves to the same horizontal line as the placement groove, under the action of spring 7 and rubber column 13, the moving plate 6 drives the left movable plate 9 and right movable plate 10 to move downwards. Under the action of spring 12, the left movable plate 9 and right movable plate 10 are respectively locked onto the clamping plate 4, thereby connecting the steel sleeve 1 and the steel collar 2. Then, the steel sleeve 1 and the steel collar 2 are welded. After the steel sleeve 1 and the steel collar 2 are reinforced, the stress concentration of the original connection part is compensated by welding, which enhances its load-bearing capacity. This effectively prevents deformation or cracking during construction or use, and improves the stability and safety of the structure. The steel collar 1 ring, after compensation and reinforcement, can better withstand the stress concentration of the original connection part. To mitigate the impact of external pressure, temperature variations, and environmental corrosion during long-term use, this design extends service life and reduces maintenance and replacement costs. The reinforced steel sleeve 2 optimizes stress distribution in the welding area, preventing localized stress concentration and resulting in a more uniform and stable overall structure under external loads, thus improving mechanical properties. The reinforced steel sleeve 1 and steel sleeve 2 are also more stable during installation, preventing installation errors caused by deformation or damage, ensuring precision during construction, and reducing additional work and repair costs due to inaccurate installation. Through welding compensation and reinforcement, the connection portion of the steel sleeve gains stronger load-bearing and fatigue resistance, reducing the failure rate during long-term use and ensuring the long-term stable operation of the entire pipeline system.
