Description

Technical Field

[0001] This invention relates to the field of steel pipe processing technology, specifically to an adjustable bracket for steel pipe processing that is easy to operate. Background Technology

[0002] In the steel pipe processing industry, support brackets, as key auxiliary equipment, bear the important task of supporting and fixing steel pipes. Their performance and ease of use directly affect the efficiency and quality of steel pipe processing. However, the steel pipe processing support brackets widely used in the market today have revealed many problems in actual use, making it difficult to meet the needs of modern steel pipe processing for high efficiency and flexibility.

[0003] Existing steel pipe processing brackets generally suffer from the drawback of fixed size. Once the dimensions and shape of these brackets are determined during design and manufacturing, they cannot be changed. When not in use, their large size and lack of adjustability occupy a significant amount of storage space. In a steel pipe processing workshop with numerous pieces of equipment and limited space, excessive space occupied by idle brackets not only wastes space but also makes the workshop layout appear cluttered, increasing the difficulty and cost of site management. For example, some large steel pipe processing enterprises possess numerous brackets of different specifications. During off-seasons or when certain brackets are not used in specific processes, these fixed-size brackets accumulate in large quantities in workshop corners, severely impacting the overall operational efficiency and space utilization of the workshop.

[0004] Furthermore, the operation of fixing steel pipes with brackets is generally quite cumbersome. Currently, most brackets use bolts and other fasteners to secure the steel pipes. In practice, workers need to manually tighten or loosen each bolt individually to fix or remove the steel pipe. This process is not only time-consuming and labor-intensive, making it quite tedious, but also, especially when frequent replacement or adjustment of the steel pipe is required, the repeated bolting significantly reduces the processing efficiency of the steel pipe. Summary of the Invention

[0005] The purpose of this invention is to provide an adjustable bracket for steel pipe processing that is easy to operate, so as to solve the problems of steel pipe processing mentioned in the background art.

[0006] To achieve the above objectives, the present invention provides the following technical solution: an adjustable bracket for easy-to-operate steel pipe processing, comprising two bracket base plates, a set of universal casters with brakes fixedly connected to the bottom of each of the two bracket base plates, and a set of lower lifting supports fixedly connected to the top of each of the two bracket base plates. A lifting upper support rod is slidably connected to the top of each of the two sets of lower lifting supports, and a connecting top plate is fixedly connected to the top of each set of upper lifting support rods. An electric telescopic rod is fixedly connected to the bottom of each of the two connecting top plates, and a clamping device for quickly fixing the steel pipe is provided on the top of each of the two connecting top plates. A mounting plate is fixedly connected to one side of the bracket base plate, and two folding rods are movably connected to one side of the mounting plate. A second mounting plate is movably connected to one end of each of the two folding rods, and a bracket controller is fixedly connected to one side of the lifting upper support rod.

[0007] Preferably, both mounting plate one and mounting plate two are U-shaped, and both mounting plate one and mounting plate two have sliding grooves on both sides, and one side of mounting plate two is fixedly connected to one side of the bracket base plate.

[0008] Preferably, the two folding rods are X-shaped, and two linkage shafts are rotatably connected between the two folding rods. Two sets of sliders are fixedly connected to one side of each of the two folding rods, and an electric telescopic rod is fixedly connected between the two linkage shafts.

[0009] Preferably, each set of sliders is provided with two sliders, and one end of one set of sliders is slidably connected to the groove of the first mounting plate, and one end of the other set of sliders is slidably connected to the groove of the second mounting plate.

[0010] Preferably, the fixed ends of the two electric telescopic rods are respectively fixedly connected to the top of the two bracket base plates, and the movable ends of the two electric telescopic rods are respectively fixedly connected to the bottom of the two connecting top plates, and the two electric telescopic rods are respectively located between the two sets of lifting lower supports.

[0011] Preferably, both clamping devices include a steel pipe placement plate, a fixed plate, a small motor, a threaded rod, a threaded block, a linkage slide rod, a connecting rod, a rotating frame, a limiting rod, and a swing rod. The top of the connecting top plate is fixedly connected to the steel pipe placement plate. Two fixed plates are fixedly connected to one side of the steel pipe placement plate, and a small motor is fixedly connected to one side of one of the fixed plates. A threaded rod is fixedly connected to the movable end of the small motor. A threaded block is fixedly connected to the outer surface of the threaded rod. A linkage slide rod is fixedly connected to one side of the threaded block. A connecting rod is movably connected to one end of the linkage slide rod. A rotating frame is fixedly connected to one end of the connecting rod. Three limiting rods are fixedly connected to one side of the steel pipe placement plate, and a swing rod is rotatably connected to one end of each of the three limiting rods.

[0012] Preferably, a movable groove is provided on one side of the connecting rod, and one end of the linkage slide rod is slidably connected in the movable groove.

[0013] Preferably, a circular groove is provided on one side of the steel pipe placement plate, and one side of the rotating frame is rotatably connected to one side of the steel pipe placement plate corresponding to the side of the circular groove.

[0014] Preferably, the outer surface of the circular groove is provided with three arc-shaped grooves, and the inner walls of the three arc-shaped grooves are all rotatably connected to limit tubes via a light rod.

[0015] Preferably, the three limiting rods are arranged in a triangle on one side of the steel pipe placement plate, and the outer surfaces of the three swing rods are slidably connected to the inside of the three limiting tubes, and one end of each of the three limiting tubes is rotatably connected to a roller.

[0016] Compared with the prior art, the beneficial effects of the present invention are: 1. This adjustable bracket retracts via an electric telescopic rod 2 operated by a bracket controller. As the electric telescopic rod 2 shortens, the distance between the two linkage shafts gradually decreases. This change causes mounting plates 1 and 2 to experience an inward pulling force, which in turn moves the two folding rods closer together. Since the two ends of the folding rods are connected to the sliding grooves on mounting plates 1 and 2 via sliders, the sliders slide within the grooves under the pulling force, guiding the folding rods to fold along a specific trajectory. This significantly reduces the space occupied by the bracket during storage, making it easy to find a suitable location for storage, whether in a factory warehouse or a workshop corner. This facilitates equipment management and storage, while also reducing site costs caused by excessive space occupied by the equipment.

[0017] 2. The bracket is equipped with casters with brakes at the bottom of the base plate, which can easily move the entire bracket to the steel pipe processing area without manual handling, saving manpower and time and improving work efficiency.

[0018] 3. The small motor is started via the bracket controller. The movable end of the small motor begins to rotate at high speed, driving the connected threaded rod to rotate synchronously. Since the threaded rod and the threaded block are connected by a thread, the rotation of the threaded rod causes the threaded block to move along the axial direction of the threaded rod. During the movement of the threaded block, it drives the linkage slide rod to move together. One end of the linkage slide rod is slidably connected in the movable groove of the connecting rod. This connection method allows the linear motion of the linkage slide rod to be converted into the oscillation of the connecting rod. The oscillation of the connecting rod then drives the rotating frame to rotate. The rotating frame is connected to the rollers through the limiting tube, causing the rollers to move in a circular motion around the limiting rod. All three rollers simultaneously move towards the steel pipe, ultimately clamping the steel pipe tightly. The entire clamping process is fast and stable, completing the fixation of the steel pipe in a short time, greatly improving processing efficiency. Moreover, the clamping force can be adjusted according to actual needs by controlling the rotation of the small motor, ensuring that the steel pipe will not loosen during processing, making the operation of the bracket simple.

[0019] 4. The roller design in the clamping device allows the steel pipe to rotate while being clamped, making it convenient for workers to perform grinding and other processing on the surface of the steel pipe without having to manually adjust the position of the steel pipe frequently, thus improving the convenience and efficiency of processing.

[0020] 5. The electric telescopic rod is controlled by the bracket controller, which can drive the connecting top plate and the steel pipe placement plate to slide within the lifting support, thereby adjusting the processing height of the entire bracket. This allows workers to process the steel pipes at a suitable height, reducing the labor intensity of workers and improving their work comfort. Attached Figure Description

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

[0024] Please see Figure 1-8This invention provides an adjustable bracket for easy-to-operate steel pipe processing, comprising two bracket base plates 1, each with a set of universal casters 2 with brakes fixedly connected to its bottom, and each with a set of lower lifting supports 3 fixedly connected to its top, and each with a slidably connected upper lifting support rod 4 to its top, each with a connecting top plate 5 fixedly connected to its top, and each with an electric telescopic rod 6 fixedly connected to its bottom, and each with a clamping device for quickly fixing the steel pipe, and a mounting plate 7 fixedly connected to one side of the bracket base plate 1, and two folding rods 9 movably connected to one side of the mounting plate 7, with a mounting plate 8 movably connected to one end of each of the two folding rods 9, and a bracket controller 13 fixedly connected to one side of the upper lifting support rod 4.

[0025] Furthermore, both mounting plate 7 and mounting plate 8 are U-shaped, and both sides of mounting plate 7 and mounting plate 8 are provided with sliding grooves. One side of mounting plate 8 is fixedly connected to one side of bracket base plate 1. The sliding grooves provided by mounting plate 7 and mounting plate 8 limit the subsequent unfolding of folding rod 9.

[0026] Furthermore, the two folding rods 9 are X-shaped, and two linkage shafts 10 are rotatably connected between the two folding rods 9. Two sets of sliders 12 are fixedly connected to one side of each of the two folding rods 9, and an electric telescopic rod 11 is fixedly connected between the two linkage shafts 10. By extending and retracting the electric telescopic rod 11, the two folding rods 9 are unfolded, thereby unfolding the entire bracket.

[0027] Furthermore, each set of sliders 12 is provided with two, and one end of one set of sliders 12 is slidably connected to the groove of the mounting plate 1 7, and one end of the other set of sliders 12 is slidably connected to the groove of the mounting plate 2 8. By sliding the sliders 12 in the grooves opened in the mounting plate 1 7 and the mounting plate 2 8, the folding rod 9 can be stably unfolded.

[0028] Furthermore, the fixed ends of the two electric telescopic rods 6 are respectively fixedly connected to the top of the two bracket base plates 1, and the movable ends of the two electric telescopic rods 6 are respectively fixedly connected to the bottom of the two connecting top plates 5, and the two electric telescopic rods 6 are respectively located between the two sets of lifting lower supports 3.

[0029] Furthermore, both clamping devices include a steel pipe placement plate 14, a fixing plate 15, a small motor 16, a threaded rod 17, a threaded block 18, a linkage slide rod 19, a connecting rod 20, a rotating frame 21, a limiting rod 22, and a swing rod 23. The top of the connecting top plate 5 is fixedly connected to the steel pipe placement plate 14. Two fixing plates 15 are fixedly connected to one side of the steel pipe placement plate 14, and a small motor 16 is fixedly connected to one side of one of the fixing plates 15. A threaded rod 17 is fixedly connected to the movable end of the small motor 16, and a threaded block 18 is fixedly connected to the outer surface of the threaded rod 17. A linkage slide rod 19 is fixedly connected to one side of the steel pipe placement plate 14. A connecting rod 20 is movably connected to one end of the linkage slide rod 19. A rotating frame 21 is fixedly connected to one end of the connecting rod 20. Three limiting rods 22 are fixedly connected to one side of the steel pipe placement plate 14. A swing rod 23 is rotatably connected to one end of each of the three limiting rods 22. The threaded rod 17 is rotated by a small motor 16. Through the linkage of the threaded block 18, the linkage slide rod 19, the connecting rod 20 and other components, the rotating frame 21 drives the roller 26 to quickly clamp and fix the steel pipe. The operation is simple and the fixing effect is reliable, which can meet the needs of steel pipe processing.

[0030] Furthermore, a movable groove is provided on one side of the connecting rod 20, and one end of the linkage slide rod 19 is slidably connected in the movable groove.

[0031] Furthermore, a circular groove 27 is provided on one side of the steel pipe placement plate 14, and one side of the rotating frame 21 is rotatably connected to one side of the steel pipe placement plate 14 corresponding to the side of the circular groove 27. Through the circular groove 27, the steel pipe is placed on the steel pipe placement plate 14, providing conditions for the subsequent rapid clamping of the steel pipe.

[0032] Furthermore, the outer surface of the circular groove 27 is provided with three arc-shaped grooves 28, and the inner walls of the three arc-shaped grooves 28 are rotatably connected to the limiting tubes 24 through the smooth rods 25. The rotating frame 21 drives one end of the roller 26 to move around the limiting rod 22 in a circular motion through the limiting tubes 24, so that one end of the three swing rods 23 drives the rollers 26 to clamp and fix the steel pipe, thereby realizing the rapid clamping of the steel pipe.

[0033] Furthermore, the three limiting rods 22 are arranged in a triangle on one side of the steel pipe placement plate 14, and the outer surfaces of the three swing rods 23 are slidably connected to the inside of the three limiting tubes 24. Each of the three limiting tubes 24 is rotatably connected to a roller 26. The roller 26 allows the steel pipe to rotate while being clamped, which facilitates the worker to perform grinding and other processing on the surface of the steel pipe without having to manually adjust the position of the steel pipe frequently, thus improving the convenience and efficiency of processing.

[0034] In this embodiment, during use: First, by pressing the switch on the bracket controller 13, the electric telescopic rod 11 is controlled to extend and retract. By increasing the distance between the two linkage shafts 10, the distance between the mounting plate 7 and the mounting plate 8 is increased, causing the mounting plate 7 and the mounting plate 8 to stretch the two folding rods 9. This causes the two folding rods 9 to drive the two sets of sliders 12 to slide in the grooves on the mounting plate 7 and the mounting plate 8, thereby increasing the distance between the two bracket base plates 1 and unfolding the entire bracket. Conversely, when not in use, the bracket is folded to reduce storage space. Then, the bracket can be easily moved to the steel pipe processing area using the universal casters 2 with brakes. The steel pipe is then placed on the two steel pipe placement plates 14 through the circular groove 27. The bracket controller 13 then starts the small motor 16, causing the movable end of the small motor 16 to drive the threaded rod 17 to rotate. Then, through the threaded connection between the threaded rod 17 and the threaded block 18, the screw... The threaded block 18 moves on the threaded rod 17, causing one end of the linkage slide rod 19 to slide within the movable groove of the connecting rod 20. This causes the connecting rod 20 to rotate the rotating frame 21, which in turn causes one end of the roller 26 to move in a circular motion around the limiting rod 22 via the limiting tube 24. This causes one end of the three swing rods 23 to clamp and fix the steel pipe with the roller 26. Similarly, another clamping device clamps and fixes one end of the steel pipe. At the same time, the steel pipe rotates while being clamped via the roller 26, making it easier for workers to perform grinding and other processing on the surface of the steel pipe. Then, the bracket controller 13 controls the electric telescopic rod 6, causing the movable ends of the two electric telescopic rods 6 to slide within the two sets of bracket controllers 13 via the connecting top plate 5. This adjusts the processing height of the entire bracket, allowing workers to process the steel pipe at a suitable height, thus simplifying the use and operation of the bracket.

[0035] Although the present invention 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 invention should be included within the protection scope of the present invention.
