Description

Technical Field

[0001] This utility model relates to the field of pipeline connection technology, and in particular to an auxiliary connection device for pipeline installation. Background Technology

[0002] In industrial production, desulfurization is a process that removes sulfur-containing compounds from gases or liquids using chemical or physical methods. In many industrial sectors, such as coal-fired power generation, steel production, and chemical industry, desulfurization is a key environmental protection measure that can reduce pollution, protect the environment, and promote sustainable development.

[0003] In desulfurization processes, pipelines are responsible for transporting desulfurizing agents (such as limestone slurry, ammonia water, etc.) from storage devices to desulfurization towers or reactors. In addition, pipelines also undertake the task of transporting flue gas. After the flue gas is discharged from the boiler or flue, it enters the desulfurization tower or reactor through pipelines for desulfurization treatment. In order to ensure that the medium can flow stably during the desulfurization process, the pipelines often bear certain pressure and temperature, which leads to frequent maintenance and repair of the pipelines. During pipeline laying or emergency repair construction, there is often a distance deviation between the connection ends of the two pipelines. In the traditional construction process, the two pipeline connection ends are usually manually held and pulled together and aligned. As a result, at least two construction workers are required to complete the pipeline connection work, which increases labor costs and reduces the efficiency of pipeline connection construction. Therefore, this application provides an auxiliary connection device for pipeline installation. Utility Model Content

[0004] The technical problem to be solved by this utility model is to provide an auxiliary connection device for pipeline installation to solve the problem that the existing pipeline connection construction is not convenient enough.

[0005] To solve the above-mentioned technical problems, this utility model provides the following technical solution: An auxiliary connection device for pipe installation, used to assist in the alignment and tightening of the ends of two pipe bodies, includes a guide rail, on which a pair of ring clamps are slidably mounted, the ring clamps being sleeved with the pipe bodies, and a lead screw is vertically and rotatably mounted at the center of the guide rail, with a sleeve block threaded onto the lead screw, and a pair of connecting arms hinged to the sleeve block, the other ends of the pair of connecting arms being respectively hinged to the pair of ring clamps; Both ends of the guide rail are provided with a pair of support frames to suspend and support the guide rail and a pair of ring clamps.

[0006] Optionally, the two connecting arms are symmetrically distributed, and the connecting arms are configured as a flat structure, with a rotating handle connected to the top of the lead screw.

[0007] Optionally, the ring clamp includes two symmetrically distributed buckle plates, which are curved in an arc shape toward opposite sides. One side of the two buckle plates is hinged to each other, and the other side of the two buckle plates is provided with a protruding plate. A through groove is provided on the pair of protruding plates, and a locking member for locking the pair of protruding plates is provided in the through groove.

[0008] Optionally, the locking component includes a stud inserted into the through groove, a lower baffle fixed to the bottom of the stud, and a hexagonal nut threaded onto the stud. The bottom of the hexagonal nut is provided with an upper baffle, and the lower baffle and the upper baffle are respectively located on the side of a pair of protrusions that are far apart from each other.

[0009] Optionally, a bushing is fitted onto the hexagonal nut, the bushing supporting detachment from the top of the hexagonal nut, and a push handle is radially fixed on the side wall of the bushing.

[0010] Optionally, the top surface of the stud is spherical, and the diameters of the lower baffle and the upper baffle are greater than the width of the through groove.

[0011] Optionally, one of the buckle plates is provided with a slider, and the guide rail is provided with a rail groove along the length direction, and the slider and the rail groove are slidably engaged.

[0012] Optionally, a pair of protrusions are provided on both sides of the top of the slider, and the pair of protrusions slide and fit against the upper and lower surfaces of the guide rail, respectively.

[0013] Optionally, multiple rubber strips are provided on the inner arc surface of the buckle plate, and the rubber strips are distributed along the arc surface of the buckle plate.

[0014] Optionally, the rubber strip has a parallelogram cross-section and the rubber strip is inclined towards the middle of the guide rail.

[0015] Compared with the prior art, this utility model has at least the following beneficial effects: In the above solution, a pair of ring clamps are set to clamp the connecting ends of the two pipes to be connected. Rotating the handle drives the screw to rotate, and the flat connecting arm limits the axial movement of the sleeve block, causing the sleeve block to move upward. This causes the pair of connecting arms to pull the pair of ring clamps closer together, and the ends of the two pipes clamped by the pair of ring clamps are aligned and abutted. The construction personnel only need to use pipe clips to clamp the ends of the two pipes. Furthermore, the support frames set at both ends of the guide rail suspend and support the guide rail and the pair of ring clamps, avoiding friction with the ground when the two pipes are connected, making the pipe connection more convenient.

[0016] This embodiment has a reasonable overall structure and has the function of assisting in tightening and aligning the two pipes, making the pipe connection more convenient. It eliminates the need for construction personnel to manually pull the two pipes together for alignment, thereby reducing labor costs and improving pipeline construction efficiency. It is suitable for various pipeline construction conditions such as emergency repair and laying. Attached Figure Description

[0027] like Figure 1 and Figure 2As shown, this embodiment of the present invention provides an auxiliary connection device for pipeline installation, used to assist in the alignment and tightening of the ends of two pipe bodies 1. It includes a guide rail 2, on which a pair of ring clamps 3 are slidably mounted. The ring clamps 3 are sleeved with the pipe bodies 1. A lead screw 4 is vertically and rotatably mounted at the center of the guide rail 2. A sleeve block 5 is threaded onto the lead screw 4, and a pair of connecting arms 6 are hinged to the sleeve block 5. The other ends of the pair of connecting arms 6 are respectively hinged to the pair of ring clamps 3. A pair of support frames 22 are provided at both ends of the guide rail 2 to suspend and support the guide rail 2 and the pair of ring clamps 3. Preferably, the support frame 22 can be a support structure with a lifting function, which can adapt to different height working conditions of the conveying pipeline for auxiliary docking operations through the lifting of the support frame 22. In this embodiment, a support frame 22 with a fixed height is described for reference.

[0028] Two connecting arms 6 are symmetrically distributed and are designed with a flat structure. A rotating handle 7 is connected to the top of the lead screw 4. A pair of ring clamps 3 are respectively clamped around the connecting ends of the two pipe bodies 1 to be connected. The rotating handle 7 drives the lead screw 4 to rotate, and the flat structure of the connecting arms 6 axially limits the sleeve block 5, causing the sleeve block 5 to move upward. This causes the pair of connecting arms 6 to pull the pair of ring clamps 3 closer together. The ends of the two pipe bodies 1 clamped by the pair of ring clamps 3 are then aligned and abutted. Construction workers only need to use pipe clips to clamp the ends of the two pipe bodies 1. Furthermore, because the support frames 22 set at both ends of the guide rail 2 suspend and support the guide rail 2 and the pair of ring clamps 3, friction between the two pipe bodies 1 and the ground is avoided when they are connected, making the pipe connection more convenient. The entire process does not require construction workers to manually pull the two pipe bodies 1 to abut and align, thus eliminating the need for multiple people to cooperate, reducing labor costs, and improving pipeline construction efficiency.

[0029] like Figure 1 , Figure 3 and Figure 4 As shown, the ring clamp 3 includes two symmetrically distributed buckle plates 9. The two buckle plates 9 are curved in an arc shape towards the opposite side. One side of the two buckle plates 9 is hinged to each other. The other side of the two buckle plates 9 is provided with a protruding plate 11. A through groove 12 is opened on the pair of protruding plates 11. A locking member 13 for locking the pair of protruding plates 11 is provided in the through groove 12. The pair of buckle plates 9 with the arc structure are conducive to being ring clamped onto the pipe body 1.

[0030] like Figure 1 , Figure 3 and Figure 4As shown, the locking member 13 includes a stud 15 passing through the through groove 12, a lower baffle 16 fixed to the bottom end of the stud 15, and a hexagonal nut 17 threaded onto the stud 15. An upper baffle 18 is provided at the bottom end of the hexagonal nut 17. The lower baffle 16 and the upper baffle 18 are respectively located on the side of a pair of protrusions 11 that are far apart from each other. A bushing 19 is fitted on the hexagonal nut 17. The bushing 19 can be disengaged from the top of the hexagonal nut 17. A push handle 20 is radially fixed on the side wall of the bushing 19. A pair of snap-on plates 9 are fastened to the tube body 1. A stud 15 is passed through a through groove 12 on one side of the pair of snap-on plates 9. A bushing 19 is fitted onto a hexagonal nut 17, and the push handle 20 is pushed to rotate the hexagonal nut 17 until the upper baffle 18 and the lower baffle 16 respectively abut against a pair of protruding plates 11, forcing the pair of snap-on plates 9 to be clamped on the tube body 1. The top surface of the stud 15 is set as a spherical surface, and the diameter of the lower baffle 16 and the upper baffle 18 is larger than the width of the through groove 12, which is conducive to the locking of the pair of snap-on plates 9. A slider 10 is provided on one of the snap-on plates 9. A rail groove 8 is opened along the length direction on the guide rail 2. The slider 10 and the rail groove 8 are slidably engaged. A pair of protruding strips 21 are provided on both sides of the top of the slider 10. The pair of protruding strips 21 are slidably attached to the upper surface and the lower surface of the guide rail 2 respectively.

[0031] like Figure 1 , Figure 3 and Figure 5 As shown, multiple rubber strips 14 are provided on the inner arc surface of the buckle plate 9. The rubber strips 14 are distributed along the arc surface of the buckle plate 9 to increase the friction between the buckle plate 9 and the tube body 1, ensuring that the two pairs of buckle plates 9 can align and abut the ends of the two tube bodies 1. The cross-section of the rubber strip 14 is a parallelogram structure, and the rubber strip 14 is inclined towards the middle of the guide rail 2. This special structure can increase the frictional resistance of the rubber strip 14 to the tube body 1, further preventing the buckle plate 9 from sliding relative to the tube body 1.

[0032] The working principle of the technical solution provided by this utility model is as follows: In use, the two pairs of buckle plates 9 are respectively looped around the connecting ends of the two pipe bodies 1 that need to be connected. The stud 15 is passed through the through groove 12 on one side of the pair of buckle plates 9. The bushing 19 is put on the hexagonal nut 17 and the push handle 20 is pushed to turn the hexagonal nut 17 until the upper baffle 18 and the lower baffle 16 respectively abut against the pair of protruding plates 11, forcing the pair of buckle plates 9 to clamp on the pipe body 1. Then, the rotating handle 7 is turned to drive the screw 4 to rotate. The flat connecting arm 6 axially limits the sleeve block 5 and drives the sleeve block 5 to move upward. Therefore, the pair of connecting arms 6 pulls the two pairs of buckle plates 9 closer to each other. The ends of the two pipe bodies 1 clamped by the two pairs of buckle plates 9 are then aligned and abutted. The construction personnel only need to use the pipe clamp to clamp the ends of the two pipe bodies 1. Because the support frames 22 set at both ends of the guide rail 2 suspend and support the guide rail 2 and a pair of ring clamps 3, the friction between the two pipe bodies 1 and the ground is avoided when they are connected, making the connection of the pipe bodies more convenient. The whole process does not require construction personnel to manually pull the two pipe bodies 1 to align, thus eliminating the need for multiple people to cooperate, reducing labor costs and improving pipeline construction efficiency.

[0033] The overall structure of this embodiment is reasonable and has the function of assisting in tightening and aligning the two pipe bodies 1, making the pipe connection more convenient. It also eliminates the need for construction personnel to manually pull the two pipe bodies 1 together for alignment, thereby reducing labor costs and improving the efficiency of pipe construction.

Furthermore, to avoid unnecessary confusion regarding the essence of this utility model, well-known methods, processes, procedures, components, and circuits are not described in detail.

[0035] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of the present utility model, and these improvements and modifications should also be considered within the protection scope of the present utility model.
