Description

Technical Field

[0001] This utility model relates to the field of steel component technology, and in particular to a recyclable steel component adjustment device. Background Technology

[0002] During bridge construction, the installation and positioning accuracy of steel components is crucial to the stability and safety of the overall bridge structure. Traditional methods for adjusting bridge structural steel components typically require the construction of temporary support frames. Construction workers then use a work platform on the top layer of the support frame to locally adjust the height of the bridge components by inserting steel plates, I-beams, or other components. In many cases, a mobile crane is needed for hoisting, and positioning is achieved through welding. This adjustment method relies on temporary support structures and various auxiliary equipment and is a common means of positioning and adjusting steel components during bridge construction.

[0003] However, traditional adjustment methods have obvious technical problems. For bridges with slopes, due to the height difference between the inner and outer sides, it is difficult to accurately control the installation error by using filling components and welding positioning, which can easily lead to insufficient installation accuracy of components. In addition, this method requires accurate calculation of the component height in advance, but during construction, due to factors such as changes in structural stress, it is often necessary to repeatedly position and adjust the components. This process not only consumes a lot of manpower and material resources, but also affects construction efficiency, making it difficult to meet the needs of modern bridge construction for efficient and precise adjustment. Utility Model Content

[0004] In view of the fact that the above-mentioned traditional bridge structural steel component adjustment methods are difficult to accurately control installation errors in the construction of bridges with slopes, and that repeated positioning and adjustment are required due to changes in structural stress during construction, resulting in a large amount of manpower and material resources being consumed and low construction efficiency, and failing to meet the needs of efficient and precise adjustment in modern bridge construction, this utility model is proposed.

[0005] To solve the above technical problems, the present invention provides the following technical solution: a recyclable steel component adjustment device, including a base, with support rods symmetrically provided on one side of the top of the base, and the lower end of the support rods is hinged to the base through a hinge joint. A support roller is rotatably installed on the upper part of one side of the support rod, and a support assembly is provided between the two support rods. The lower end of the support assembly is hinged to the base through a hinge joint. A locking assembly is provided on one side of the support assembly. The support assembly includes a bidirectional lead screw, with movably connected support sections fitted on the outer sides of both ends of the bidirectional lead screw. A sleeve is fitted on the outer wall of the bidirectional lead screw between the support sections. One end of the upper support section is connected to a connecting end, which is hinged to the upper ends of the two support rods respectively via pins.

[0006] As a preferred embodiment, the locking assembly includes a fixing block, which is fixedly installed at a corresponding position on one side of the support section. A guide rod is provided between the two fixing blocks, and both ends of the guide rod pass through the two fixing blocks and are connected to stops. A support frame and a sliding sleeve are slidably sleeved on the outer wall of the guide rod between the fixing blocks. One end of the support frame is rotatably sleeved on the outer side of one end of the sleeve. A pawl is rotatably sleeved on the outer side of the sliding sleeve. A ratchet wheel that is adapted to and engages with the pawl is sleeved on the outer wall of the sleeve. A torsion spring is sleeved on the outer side of the sliding sleeve, and both ends of the torsion spring are fixedly connected to the sliding sleeve and the pawl, respectively. An adjustment component connected to the sliding sleeve is provided on the top of the support frame.

[0007] As a preferred embodiment, the adjusting component includes a screw, and the top of the support frame has an adjusting groove. The screw is rotatably installed in the adjusting groove, and one end of the screw extends to the outside of the support frame and is connected to a handle. A connecting block is threadedly connected to the outer wall of the screw, and the connecting block is located in the adjusting groove. The lower end of the connecting block is fixedly connected to a sliding sleeve.

[0008] As a preferred embodiment, the guide rod has a rectangular cross-section and is slidably connected to the fixed block. The support frame has an L-shaped structure, and the support frame and the pawl are rotatably connected to the sleeve and the sliding sleeve respectively through bearings.

[0009] As a preferred embodiment, the connecting end has a U-shaped structure and is fixedly connected to the support section.

[0010] As a preferred embodiment, a mounting bracket is fixedly installed on one side of the support rod, and a connecting shaft is provided between the two mounting brackets. Both ends of the connecting shaft pass through the mounting brackets on both sides. The connecting shaft is rotatably connected to the mounting bracket through bearings. The support roller is sleeved on the outer wall of the connecting shaft and is located inside the mounting bracket.

[0011] Compared with the prior art, the present invention has at least the following beneficial effects: 1. This utility model has a simple structure, is convenient and safe to operate, can improve the adjustment efficiency of bridge components, is easy for workers to set up, and saves time and effort. By adjusting the extension and retraction of the support section through the bidirectional screw, the angle of the support rod can be adjusted to provide support for the installation frame. The triangular structure formed by the base, support rod and support section is stable and ensures the safety of adjustment, and has good application prospects.

[0012] 2. The locking assembly of this utility model allows the sleeve to rotate only in the direction that drives the bidirectional lead screw to move outwards relative to the two support sections. During reverse rotation, the pawl and ratchet engage to lock the bidirectional lead screw, preventing it from reversing. This automatically locks the position after the device is adjusted to the desired angle, preventing changes in the length and angle of the support section and bidirectional lead screw assembly due to changes in the force on the bridge components. This reduces repeated adjustments and makes it more convenient to use. When it is necessary to shorten the length of the support section and bidirectional lead screw assembly, the torsion screw drives the connecting block and sliding sleeve to slide on the guide rod, causing the pawl and ratchet to misalign, thus releasing the lock and allowing for reverse rotation for adjustment.

[0015] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings.

[0016] Reference Figure 1 - Figure 4As shown, a recyclable steel component adjustment device is provided, including a base 1. Support rods 2 are symmetrically positioned on one side of the top of the base 1, and the lower ends of the support rods 2 are hinged to the base 1 via a hinge connector. In this example, the hinge connector consists of two pin connecting plates and a fixing pin to hinge the support rods 2 to the base 1. Support rollers 9 are rotatably mounted on the upper part of one side of each support rod 2. A support assembly is provided between the two support rods 2, and the lower end of the support assembly is hinged to the base 1 via a hinge connector. In this example, the hinge connector 2 consists of a pin connecting plate and a fixing pin to hinge the lower support section 3 to the base 1. A locking assembly is provided on one side of the support assembly. The symmetrically arranged support rods 2 and the support assembly, in conjunction with the support assembly, form a stable triangular support structure, improving the overall load-bearing capacity and adjustment stability of the device. Simultaneously, the support rollers 9 can flexibly adapt to the surface of the bridge components, reducing contact wear. The support assembly includes a bidirectional lead screw 4, with movable support sections 3 fitted on the outer sides of both ends of the bidirectional lead screw 4. A sleeve 5 is fitted between the support sections 3 and the outer wall of the bidirectional lead screw 4. One end of the upper support section 3 is connected to a connecting end 6, which is hinged to the upper ends of the two support rods 2 via pins 7. The cooperation between the bidirectional lead screw 4 and the support sections 3 enables the synchronous reverse extension and retraction of the support sections 3 at both ends, precisely adjusting the angle of the support rods 2 to adapt to the height difference requirements of bridges with different slopes. The hinged structure of the connecting end 6 and the pin 7 ensures the flexibility of angle adjustment.

[0017] In this example, the locking assembly includes a fixing block 11, which is fixedly installed on one side of the support section 3 at a corresponding position. A guide rod 12 is provided between the two fixing blocks 11, and both ends of the guide rod 12 pass through the two fixing blocks 11 and are connected to the stop blocks 13. A support frame 14 and a sliding sleeve 15 are slidably sleeved on the outer wall of the guide rod 12 between the fixing blocks 11. One end of the support frame 14 is rotatably sleeved on the outer side of one end of the sleeve 5. A pawl 16 is rotatably sleeved on the outer side of the sliding sleeve 15. A sleeve 16 that is adapted to and engages with the pawl 16 is sleeved on the outer wall of the sleeve 5. The ratchet 18 and the outer side of the sliding sleeve 15 are fitted with a torsion spring 17, and the two ends of the torsion spring 17 are fixedly connected to the sliding sleeve 15 and the pawl 16 respectively. The top of the support frame 14 is provided with an adjustment component connected to the sliding sleeve 15. The meshing cooperation between the pawl 16 and the ratchet 18 realizes the one-way locking of the bidirectional screw 4. The torsion spring 17 ensures that the pawl 16 is stably engaged, avoiding the retraction of the support section 3 caused by the force on the bridge component. The sliding structure of the guide rod 12 and the sliding sleeve 15 provides a stable guide for the switching of the locking state, improving the safety of the device.

[0018] In this example, the adjusting component includes a screw 19. An adjusting groove is provided on the top of the support frame 14. The screw 19 is rotatably installed in the adjusting groove, and one end of the screw 19 extends to the outside of the support frame 14 and is connected to a handle. A connecting block 20 is threadedly connected to the outer wall of the screw 19, and the connecting block 20 is located in the adjusting groove. The lower end of the connecting block 20 is fixedly connected to the sliding sleeve 15. Through the threaded transmission between the screw 19 and the connecting block 20, the sliding sleeve 15 can be precisely controlled to drive the pawl 16 to disengage from the ratchet 18, realizing a quick switch of the locking state. The handle is easy to operate, requiring no complicated tools and reducing the difficulty of operation for construction personnel.

[0019] In this example, the guide rod 12 has a rectangular cross-section and is slidably connected to the fixed block 11. The support frame 14 has an L-shaped structure. The support frame 14 and the pawl 16 are rotatably connected to the sleeve 5 and the sliding sleeve 15 respectively through bearings. The rectangular cross-section of the guide rod 12 can prevent the sliding sleeve 15 and the support frame 14 from rotating, ensuring the stability of the movement direction of each component of the locking assembly. The bearing connection reduces rotational friction, improves the smoothness of adjustment and the service life of the components.

[0020] In this example, the connecting end 6 is a U-shaped structure and is fixedly connected to the support section 3; this enhances connection stability, improves angle adjustment flexibility, increases structural strength, and facilitates installation.

[0021] In this example, a mounting bracket 8 is fixedly installed on one side of the support rod 2, and a connecting shaft 10 is provided between the two mounting brackets 8. Both ends of the connecting shaft 10 pass through the mounting brackets 8 on both sides. The connecting shaft 10 is rotatably connected to the mounting bracket 8 through bearings. The support roller 9 is sleeved on the outer wall of the connecting shaft 10 and is located inside the mounting bracket 8. The combination of the mounting bracket 8 and the connecting shaft 10 provides stable support for the support roller 9. The bearing connection ensures that the roller rotates flexibly, reduces the frictional resistance when adjusting the bridge components, and avoids scratching the surface of the components.

[0022] During use, the base 1 is hinged to the lower end of the support rod 2 via a hinge connector to form a support foundation. In the support assembly, the bidirectional lead screw 4 cooperates with the support section 3, and drives the two support sections 3 at both ends to extend and retract synchronously in opposite directions through the rotating sleeve 5. The upper support section 3 is hinged to the upper ends of the two support rods 2 via the U-shaped connecting end 6 and the pin shaft 7, thereby adjusting the angle of the support rods 2, so that the support rollers 9 on the mounting frame 8 can rotate flexibly through the connecting shaft 10 to support the bridge components. In the locking assembly, the fixing block 11, the guide rod 12 and the stop block 1 The 3-section forms a guiding structure. The support frame 14 and the sliding sleeve 15 can slide along the guide rod 12. The pawl 16 engages with the ratchet 18 under the action of the torsion spring 17, realizing the one-way locking of the two-way screw 4 and preventing the support section 3 from retracting. In the adjustment component, rotating the screw 19 handle drives the connecting block 20 to move, causing the sliding sleeve 15 to drive the pawl 16 to disengage from the ratchet 18, releasing the lock for reverse adjustment. The whole structure is stably stressed by the triangular structure formed by the base 1, the support rod 2 and the support section 3, completing the angle adjustment and safety support of the bridge steel components.
