Description

Technical Field

[0001] This utility model relates to the field of steel pipe manufacturing technology, specifically to an auxiliary device for adjusting the roundness of steel pipes and assembling stiffening rings. Background Technology

[0002] In the steel pipe processing and manufacturing industry, the rounding of steel pipes and the assembly of stiffening rings are crucial processes. However, existing stiffening ring assemblies have some significant problems in use.

[0003] In the traditional process of rounding steel pipes and assembling stiffening rings, there is a lack of flexible and precise adjustment mechanisms for steel pipes of different diameters. Fixed-size clamping devices are usually used, which requires a lot of time and manpower to replace clamping components of different specifications, seriously affecting work efficiency. Due to the lack of advanced equipment, it is only possible to rely on manual labor to fix the steel pipe and stiffening ring with simple clamps. This not only makes it difficult to ensure the roundness of the steel pipe, but also results in inaccurate clamping position of the stiffening ring, leading to inconsistent assembly quality of the stiffening ring and the steel pipe, which affects the overall performance and service life of the steel pipe.

[0004] For example, in the case of a high-efficiency pressure steel pipe stiffening ring assembly device with announcement number CN222492868U, the side plates are perpendicular to the pressure steel pipe, and stiffening ring hooks are fixedly installed at the ends of the two outermost side plates near the pressure steel pipe. By using stiffening ring hooks to hook the pressure steel pipe, and with the cooperation of telescopic components, the stiffening ring is pushed close to the pressure steel pipe, so that the stiffening ring and the pressure steel pipe can be welded.

[0005] For example, in the simplified device for assembling stiffening rings for pressure steel pipes (announcement number CN203380561U), the support panel and the track fixing frame are welded together. The track is fixed to the support panel via the track fixing frame. One end of the side pull plate is fitted onto the track. A spring is placed inside the sleeve to support the track. A jack is placed on the track but not connected to it. In use, this simplified device for assembling stiffening rings for pressure steel pipes, while having a flexible adjustment mechanism for steel pipes of different diameters, often requires frequent replacement of the clamping components and is prone to damaging the stiffening rings and the pipe wall. However, other issues also exist. The existing methods for adjusting the position of stiffening rings are often crude, lacking precision and convenience. Common hoisting equipment can only perform simple up-and-down movements when adjusting the position of the stiffening ring, making it very difficult to adjust the position of the stiffening ring in the circumferential and horizontal directions of the steel pipe. In large steel pipe processing projects, due to the large size of the steel pipe and the stiffening ring, manually adjusting the position of the stiffening ring is not only dangerous, but also makes it difficult to ensure the relative positional accuracy of the stiffening ring and the steel pipe. This may result in the stiffening ring not being able to evenly distribute the pressure borne by the steel pipe, affecting the mechanical properties of the steel pipe in actual use. Utility Model Content

[0006] The purpose of this utility model is to provide an auxiliary device for adjusting the roundness of steel pipes and assembling stiffening rings, so as to solve the problems in the background art that the flexible adjustment mechanism for steel pipes of different diameters often requires frequent replacement of clamping components, and is prone to damage to the stiffening ring and steel pipe wall. The adjustment method is also rough and inaccurate, the adjustment range of the hoisting equipment is limited, and manual adjustment is dangerous and difficult to guarantee accuracy.

[0007] To achieve the above objectives, this utility model provides the following technical solution: an auxiliary device for adjusting the roundness of steel pipes and assembling stiffening rings, comprising a working platform and a base fixedly installed on the upper part of the working platform; three bases are evenly distributed on the working platform, and a movable plate is movably installed on the right side inside the base, with two movable plates evenly distributed around the base as the center of symmetry; a hydraulic press is fixedly installed on the upper part of the movable plate; an adjustment mechanism is provided on the base, and a clamping plate is installed at the output end of the hydraulic press; a first guide plate is fixedly installed above the front end of the working platform, with two first guide plates evenly distributed around the working platform as the center of symmetry; a hoisting mechanism is provided on the upper part of the working platform, and a support frame is provided on the upper part of the working platform.

[0008] Furthermore, the adjustment mechanism includes a buffer pad installed on the inner side of the card plate, and a steel pipe body is provided on the inner side of the buffer pad. A guide block is provided below the front end of the moving plate, and two guide blocks are evenly distributed with the base as the center of symmetry.

[0009] Furthermore, the base has a guide groove at its front end, and two guide grooves are evenly distributed with the base as the center of symmetry. The guide grooves cooperate with the guide blocks. A helical rod is rotatably installed inside the base and is rotatably installed below the moving plate. A rotating handle is fixedly installed at the right end of the helical rod.

[0010] Furthermore, the upper end of the buffer pad has a placement groove, and the placement grooves are evenly distributed in four or three positions on the buffer pad. An installation plate is provided inside the placement groove, and the left end of the installation plate is fixedly installed on the right end of the card plate. A fixing plate is rotatably installed on the right end of the installation plate, and two fixing plates are evenly distributed around the installation plate as the center of symmetry. A compression spring is installed on the upper end of the card plate, and the left end of the compression spring is installed in the middle of the upper end of the fixing plate.

[0011] Furthermore, the hoisting mechanism includes a first guide wheel fixedly installed at the lower end of the support frame, and four first guide wheels are evenly distributed around the support frame as the center of symmetry, and the first guide wheels cooperate with the first guide plate.

[0012] Furthermore, a second guide plate is fixedly installed on the upper right side of the support frame. Two second guide plates are evenly distributed around the support frame as the center of symmetry. A traction machine is provided on the upper part of the second guide plate, and a second guide wheel is rotatably installed on the front right side of the traction machine.

[0013] Furthermore, the second guide wheel cooperates with the second guide plate, and a traction rope is provided at the lower end of the traction machine, with a stiffening ring body provided at the lower end of the traction rope.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] 1. The hydraulic press at the top of the moving plate pushes the clamping plate inward, fixing the steel pipe body. The fixing plate inside the slot contacts the outside of the steel pipe body, causing the fixing plate to unfold. The fixing plate then fixes the steel pipe body again. When the steel pipe body is too small, the user turns the handle, which drives the screw rod to rotate. The screw rod drives the moving plate to move. The guide blocks on both sides of the moving plate cooperate with the guide grooves on both sides inside the base. The secondary clamping provides more stable support and constraint, effectively resisting these external forces and preventing the steel pipe from shifting when assembling the stiffening ring. It can adapt to steel pipes of different diameters, improve clamping efficiency, and eliminate the need for frequent component replacement.

[0016] Furthermore, it can quickly and accurately adapt to steel pipes of various diameters, whether it is a large-diameter oil pipeline or a small-diameter precision instrument steel pipe, it can achieve stable clamping without frequent replacement of clamping parts, which greatly improves work efficiency and can complete the rounding and stiffening ring assembly preparation work of steel pipes of different specifications in a short time.

[0017] Furthermore, it can clamp the pipes when switching between different diameters, allowing the production line to maintain efficient and continuous operation, improving overall production efficiency. Compared with traditional methods, it reduces equipment procurement costs, reduces equipment storage space requirements, and reduces the manpower required for manual replacement of clamping parts. The complex equipment replacement work that originally required multiple people to complete can now be easily completed by a single person, significantly reducing labor costs.

[0018] 2. The traction rope at the lower end of the traction machine drives the stiffening ring body. The second guide wheels on both sides of the traction machine cooperate with each other through the second guide plate at the upper end of the support frame to adjust the front and rear position of the stiffening ring body. The first guide plate at the upper end of the work platform cooperates with the first guide wheel at the lower end of the support frame to adjust the left and right position of the stiffening ring body. For large steel pipes and stiffening rings, this significantly reduces the labor intensity and safety risks for operators.

[0019] Furthermore, the stiffening ring can be accurately assembled into the ideal position around the steel pipe, ensuring that the relative positional accuracy between the stiffening ring and the steel pipe is within a very small error range. This allows the stiffening ring to evenly distribute the pressure when the steel pipe is under stress, thus improving the mechanical properties of the steel pipe. Steel pipes equipped with stiffening rings using this device have improved load-bearing capacity and stability when subjected to the same pressure. Attached Figure Description
