Description

Technical Field

[0001] This patent relates to the field of pipeline engineering installation technology, specifically a portable pipeline docking support. Background Technology

[0002] Pipeline construction often involves splicing multiple shorter pipes into a longer one to meet specific needs. Conventional metal pipes are usually connected by welding or flanges. The installation process requires positioning and support of the pipes using pipe connection brackets. However, traditional pipe connection brackets are mostly fixed structures, which are large and heavy, and lack a dedicated portable design. For example, some brackets rely on bolt assemblies to connect multiple parts, making disassembly and assembly time-consuming and labor-intensive. They are difficult to adapt to the rapid transportation needs of field operations, high-altitude operations, or construction in confined spaces. On-site construction personnel need to be equipped with additional lifting equipment or work in multiple people to carry the pipes, which significantly increases operating costs. Utility Model Content

[0003] The purpose of this patent is to provide a portable pipe connection support to solve the problems mentioned in the background art.

[0004] To achieve the above objectives, this patent provides the following technical solution: a portable pipe docking bracket, comprising a main board and a secondary board, wherein the upper surfaces of the main board and the secondary board are provided with placement grooves, the cross-section of the placement grooves is an inverted trapezoid, and the external pipes to be docked and welded can be placed in the placement grooves;

[0005] Both the main board and the sub-board have holes on their upper walls, and a handle is installed on the side wall of the main board.

[0006] Both the main board and the sub-board have through holes on their side walls. A lead screw is rotatably installed in the through hole. The lead screw passes through the through hole and through the side wall of the sub-board. A lead screw slider is slidably installed on the outside of the lead screw. A connecting plate is installed on the side wall of the lead screw slider. A support block is installed on both the left and right sides of the connecting plate. The upper wall of the support block is inclined. The lower wall of the sub-board has an inclined groove that matches the support block. The support block can be inserted into the inclined groove to support the sub-board.

[0007] Preferably, a sliding groove is provided on the side wall where the main board body and the sub-board body fit together, and a sliding block is installed on the side wall of the sub-board body. The sliding block is slidably installed in the sliding groove, and the cross-section of the sliding groove and the sliding block are both T-shaped.

[0008] Preferably, the side wall of the main board is provided with scale lines, and the side wall of the sub-board is provided with indicator lines, the indicator lines corresponding to the scale lines.

[0009] Preferably, a sleeve is installed at the end of the lead screw away from the lead screw slider, and a rotating handle is installed on the side wall of the sleeve.

[0010] Preferably, the sleeve has a square hole on its side wall, and the rotating handle has a square insert on its side wall, which can be inserted into the square hole.

[0011] Preferably, the upper wall of the top holding block is provided with a spherical groove, and a ball bearing is installed in the spherical groove, which can be in contact with the top wall of the inclined groove.

[0012] Compared with existing technologies, the beneficial effects of this patent are:

[0013] This device is mainly composed of a main board and a sub-board. Its structure is relatively simple. At the same time, the design of holes and handles greatly reduces the overall weight of the device, making it more convenient to carry.

[0014] In addition, this device is also equipped with a lead screw, a lead screw slider, and a top holding block. The top holding block can push the sub-plate upward, thereby raising one of the pipes to be welded. This ensures that the two pipes can be set concentrically when their diameters are different, which facilitates subsequent welding. Attached Figure Description

Detailed Implementation

[0019] The technical solutions of this patent embodiment will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this patent, and not all of them. Based on the embodiments of this patent, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this patent.

[0020] Please see Figure 1-3This patent provides a technical solution: a portable pipe docking bracket, including a main plate 1 and a secondary plate 2. The upper surfaces of the main plate 1 and the secondary plate 2 are provided with placement grooves 3. The cross-section of the placement grooves 3 is an inverted trapezoid, and the pipes to be docked and welded can be placed in the placement grooves 3.

[0021] Both the main board 1 and the sub-board 2 are made of high-strength lightweight alloy material, which combines structural rigidity and portability. At the same time, the setting of the holes 4 can greatly reduce the weight of the device.

[0022] The design of the inverted trapezoidal placement groove 3 can form a two-way limit for the pipe, and the inclined sidewall provides radial support to prevent the pipe from rolling or shifting during the butt welding process. It is suitable for cylindrical pipes of different specifications.

[0023] Meanwhile, the inner wall of its placement groove 3 is treated with anti-slip material to enhance the friction with the outer surface of the pipe;

[0024] Both the main board body 1 and the sub-board body 2 have holes 4 on their upper walls, and a handle 5 is installed on the side wall of the main board body 1.

[0025] The handle 5 makes it easy for staff to pick up and carry this device;

[0026] Both the main body 1 and the sub-body 2 have through holes 6 on their side walls. A lead screw 7 is rotatably installed in the through hole 6. The lead screw 7 passes through the through hole 6 and penetrates the side wall of the sub-body 2. A lead screw slider 8 is slidably installed on the outside of the lead screw 7. A connecting plate 9 is installed on the side wall of the lead screw slider 8. A top holding block 10 is installed on both the left and right sides of the connecting plate 9. The upper wall of the top holding block 10 is inclined. The lower wall of the sub-body 2 has an inclined groove 11 that cooperates with the top holding block 10. The top holding block 10 can be inserted into the inclined groove 11 to hold the sub-body 2.

[0027] To facilitate the connection of pipes of different diameters, this device is equipped with a lead screw 7, a lead screw slider 8, and a top holding block 10. During connection, by rotating the lead screw 7, the lead screw slider 8 drives the top holding block 10 to insert into the inclined groove 11, which lifts the sub-plate 2 upward, thereby raising the pipe on the sub-plate 2 and adjusting the pipe to be concentric with the pipe on the main plate 1, which facilitates the subsequent welding operation.

[0028] During the insertion of the top holding block 10 into the inclined groove 11, the inclined surface of the upper wall of the top holding block 10 and the inclined surface of the inclined groove 11 cooperate with each other. According to the principle of force decomposition, the force applied by the top holding block 10 to the inclined groove 11 will generate an upward component force, thereby lifting the sub-plate 2 upward and raising the pipe on the sub-plate 2 to adjust the pipe to be concentric with the pipe on the main plate 1, which facilitates the subsequent welding operation. This adjustment method has the characteristics of high precision and simple operation, and can quickly adapt to the docking requirements of pipes of different diameters.

[0029] Specifically, a sliding groove 12 is provided on the side wall where the main board 1 and the sub-board 2 are in contact, and a sliding block 13 is installed on the side wall of the sub-board 2. The sliding block 13 can be slidably installed in the sliding groove 12, and the cross-section of the sliding groove 12 and the sliding block 13 are both T-shaped.

[0030] The T-shaped sliding groove 12 and the sliding block 13 work together to not only restrict the horizontal movement of the sub-plate 2, ensuring that the sub-plate 2 will not shift laterally during the adjustment process, but also allow the sub-plate 2 to slide up and down along the direction of the sliding groove 12, providing a stable guiding structure for the adjustment of the pipe height.

[0031] Specifically, the side wall of the main board 1 is provided with scale lines 14, and the side wall of the sub-board 2 is provided with indicator lines 15, which correspond to the scale lines 14.

[0032] The scale line 14 and the indicator line 15 form a simple measurement system. When adjusting the height of the sub-plate 2, the staff can observe the position of the indicator line 15 on the scale line 14 to intuitively understand the height of the sub-plate 2 rising or falling, thereby accurately controlling the height difference between the two pipes and ensuring that the concentricity of the pipe connection reaches the ideal state.

[0033] Specifically, a sleeve 16 is installed at the end of the lead screw 7 away from the lead screw slider 8, and a rotating handle 17 is installed on the side wall of the sleeve 16.

[0034] The rotating handle 17 provides a convenient operating point for workers to apply force. By holding the rotating handle 17 and rotating it, the lead screw 7 can be easily rotated.

[0035] Specifically, a square hole 18 is provided on the side wall of the sleeve 16, and a square insert 19 is installed on the side wall of the rotating handle 17. The square insert 19 can be inserted into the square hole 18.

[0036] When the device needs maintenance or transportation, the rotating handle 17 can be removed from the sleeve 16 to reduce the space occupied by the device and make it easier to carry and store. When in use, simply align the square insert 19 with the square hole 18 and insert it to quickly restore the connection between the rotating handle 17 and the sleeve 16. The operation is very convenient.

[0037] Specifically, the upper wall of the top support block 10 is provided with a spherical groove 20, and a ball bearing 21 is installed in the spherical groove 20. The ball bearing 21 can fit against the top wall of the inclined groove 11.

[0038] During the process of the top holding block 10 being inserted into or withdrawing from the inclined groove 11, the ball 21 rolls in the spherical groove 20, which greatly reduces the friction between the two, making the lifting and lowering adjustment of the sub-plate 2 smoother. It also reduces the wear of the top holding block 10 and the inclined groove 11, and extends the service life of the device.

[0039] Working principle: When performing pipe connection work, first place the main board 1 and the sub-board 2 in the appropriate working position, and then place the two pipes to be connected into the placement slots 3 of the main board 1 and the sub-board 2 respectively.

[0040] Next, the radii of the two pipes are measured and the difference between them is calculated. The operator holds the rotating handle 17 and drives the lead screw 7 to rotate through the cooperation of the square insert 19 and the square hole 18 on the sleeve 16. When the lead screw 7 rotates, the lead screw slider 8 moves along the axis of the lead screw 7, which in turn drives the connecting plate 9 and the top holding block 10 to move. The top holding block 10 is inserted into the inclined groove 11 on the lower wall of the sub-plate 2. The interaction between the inclined surface of the upper wall of the top holding block 10 and the inclined surface of the inclined groove 11 lifts the sub-plate 2 upward. At the same time, the scale line 14 and the indicator line 15 are observed to precisely adjust the height of the sub-plate 2 until the pipe on the sub-plate 2 and the pipe on the main plate 1 are concentric. Then the subsequent welding operation can be carried out. After the welding is completed, the lead screw 7 is rotated in the opposite direction to make the top holding block 10 exit from the inclined groove 11. The sub-plate 2 is lowered, and then the welded pipe is taken out from the placement groove 3, completing one pipe connection operation.
