Abstract
Description
Technical Field
[0001] This utility model relates to the field of auxiliary technology for repairing overhead pipelines, specifically an overhead pipeline repair device. Background Technology
[0002] Overhead pipeline joint repair, also known as overhead pipeline corrosion protection, is a measure to slow down or prevent overhead pipelines from being eroded and deteriorated by the chemical and electrochemical effects of internal and external media or by the metabolic activities of microorganisms.
[0003] Existing overhead pipeline joint repair methods typically employ a two-layer design of high-density polyethylene electrofusion sleeve and heat shrinkable tape to improve the corrosion resistance of the overhead pipeline. During the installation of the electrofusion sleeve, the overhead pipeline and the electrofusion sleeve are often fixed together by fillet welding. However, when performing fillet welding on the overhead pipeline and the electrofusion sleeve, operators often need to change their welding positions back and forth to achieve full coverage of the fillet weld between the overhead pipeline and the electrofusion sleeve.
[0004] Therefore, it is necessary to propose a device for patching overhead pipelines to solve the above problems. Utility Model Content
[0005] The purpose of this invention is to provide an overhead pipeline patching device to solve the problems mentioned in the background art.
[0006] To achieve the above objectives, this utility model provides the following technical solution:
[0007] An overhead pipeline joint repair device includes a first clamping plate and a second clamping plate, which are connected together by a hinge. The first clamping plate has a first arc-shaped groove and a clamping structure therein. The second clamping plate has a second arc-shaped groove. A connecting rod is installed on the surface of the first and second clamping plates. A first fixing plate is installed on the surface of the first clamping plate and a second fixing plate is installed on the surface of the second clamping plate. A handle mechanism is installed on the surface of the first and second fixing plates. A pulley structure is installed below the first clamping plate and above the second clamping plate, respectively.
[0008] Furthermore, the clamping structure includes a third arc-shaped groove formed within the first arc-shaped groove, an elastic element is installed within the third arc-shaped groove, and an arc-shaped block is installed on the other side of the elastic element.
[0009] Furthermore, the handle mechanism includes a first hinge block mounted on the surface of the second fixed plate, the first hinge block being connected to the surface of the second fixed plate by a first ball bearing, a first pull rod being installed inside the first hinge block, the first pull rod being installed inside the first hinge block by a first connecting rod, and an insert rod being installed on the surface of the first pull rod.
[0010] Furthermore, a second hinge block is installed on the surface of the first fixed plate below the first hinge block. The second hinge block is connected to the surface of the first fixed plate by a second ball bearing. A second pull rod is installed inside the second hinge block. The second pull rod is installed inside the second hinge block by a second connecting rod. An insertion hole is installed on the surface of the second pull rod.
[0011] Furthermore, the pulley structure includes a base installed below the first clamping plate and above the second clamping plate. A fixed platform is installed below the base. The fixed platform is connected to the base by a third ball bearing. A roller is installed inside the fixed platform, and the roller is installed inside the fixed platform in the form of a pin.
[0012] Furthermore, the insertion rod and the insertion hole are connected by a snap-fit mechanism.
[0013] Furthermore, the first, second, and third balls can all rotate 360 degrees.
[0014] Furthermore, the pulley structure can be pulled by a handle mechanism.
[0015] Compared with the prior art, the technical effects and advantages of this utility model are as follows: The overhead pipeline joint repair device provided by this utility model, by setting a handle mechanism and a pulley structure, ensures that the electrothermal fusion sleeve and the overhead pipeline rotate in the same proportion, avoiding misalignment between the electrothermal fusion sleeve and the overhead pipeline during rotation. More importantly, by using the handle mechanism and pulley structure to rotate the overhead pipeline and the electrothermal fusion sleeve, the process of frequently changing the welding position when performing fillet welding between the overhead pipeline and the electrothermal fusion sleeve is avoided, which greatly improves the efficiency of fillet welding. Furthermore, by adjusting the clamping structure, the clamping components can clamp the overhead pipeline, and the adjustment of the clamping structure can meet the clamping requirements of overhead pipelines and electrothermal fusion sleeves of different diameters.

[0030] Please see Figures 1 to 9 This utility model provides a technical solution:
[0031] An overhead pipeline joint repair device includes a first clamping plate 1 and a second clamping plate 2, which are connected together by a hinge 3. The first clamping plate 1 has a first arc-shaped groove 4 and a clamping structure 5. The second clamping plate 2 has a second arc-shaped groove 6. A connecting rod 7 is installed on the surface of the first clamping plate 1 and the second clamping plate 2. A first fixing plate 8 is installed on the surface of the first clamping plate 1 and a second fixing plate 9 is installed on the surface of the second clamping plate 2. A handle mechanism 10 is installed on the surface of the first fixing plate 8 and the second fixing plate 9. A pulley structure 11 is installed below the first clamping plate 1 and above the second clamping plate 2, respectively.
[0032] In the specific implementation process, such as Figure 1 The clamping structure 5 shown includes a third arc-shaped groove 51 formed in the first arc-shaped groove 4, an elastic element 52 is installed in the third arc-shaped groove 51, and an arc-shaped block 53 is installed on the other side of the elastic element 52.
[0033] It should be noted that the third arc groove 51, which is set in the first arc groove 4, has an elastic element 52 installed in it, and an arc block 53 installed on the other side of the elastic element 52. When the pipe needs to be positioned, the worker puts the pipe into the first arc groove 4. The elastic element 52 and the arc block 53 in the third arc groove 51 will exert a reaction force on the pipe. Then, the second clamping plate 2 and the first clamping plate 1 are rotated and closed by the hinge 3, thereby achieving the effect of positioning the pipe.
[0034] In the specific implementation process, such as Figure 7The handle mechanism 10 shown includes a first hinge block 101 mounted on the surface of a second fixed plate 9. The first hinge block 101 is connected to the surface of the second fixed plate 9 by a first ball bearing 102. A first pull rod 103 is installed inside the first hinge block 101. The first pull rod 103 is mounted inside the first hinge block 101 by a first connecting rod 104. An insert rod 105 is installed on the surface of the first pull rod 103. A second hinge block 106 is mounted on the surface of a first fixed plate 8 below the first hinge block 101. The second hinge block 106 is connected to the surface of the first fixed plate 8 by a second ball bearing 107. A second pull rod 108 is installed inside the second hinge block 106. The second pull rod 108 is mounted inside the second hinge block 106 by a second connecting rod 109. An insertion hole 1010 is installed on the surface of the second pull rod 108.
[0035] It should be noted that the system includes a first hinge block 101 mounted on the surface of the second fixed plate 9, which is connected to the surface of the second fixed plate 9 by a first ball bearing 102. A first pull rod 103 is installed inside the first hinge block 101, and the first pull rod 103 is mounted inside the first hinge block 101 by a first connecting rod 104. An insert rod 105 is installed on the surface of the first pull rod 103. A second hinge block 106 is mounted on the surface of the first fixed plate 8 below the first hinge block 101, and the second hinge block 106 is connected to the surface of the first fixed plate 8 by a second ball bearing 107. A second pull rod 108 is installed inside the second hinge block 106. The second connecting rod 109 is installed inside the second hinge block 106. An insertion hole 1010 is installed on the surface of the second pulling rod 108. After the worker positions the pipe through the clamping structure 5, in order to avoid the worker frequently changing the welding position when performing fillet welding between the overhead pipe and the electrothermal sleeve, the worker pulls the first pulling rod 103 installed on the surface of the second fixed plate 9 and the second pulling rod 108 installed on the surface of the first fixed plate 8. This will pull the pulley structure 11 installed below the first clamping plate 1 and above the second clamping plate 2, thereby pulling the entire device. This avoids the worker frequently changing the welding position when performing fillet welding between the overhead pipe and the electrothermal sleeve, improving work efficiency and reducing working time.
[0036] In the specific implementation process, such as Figure 8 The pulley structure 11 shown includes a base 111 installed below the first clamping plate 1 and above the second clamping plate 2. A fixed platform 112 is installed below the base 111. The fixed platform 112 is connected to the base 111 by a third ball bearing 113. A roller 114 is installed in the fixed platform 112. The roller 114 is installed in the fixed platform 112 in the form of a pin 115.
[0037] It should be noted that the base 111 is installed below the first clamping plate 1 and above the second clamping plate 2. A fixed platform 112 is installed below the base 111. The fixed platform 112 is connected to the base 111 by a third ball bearing 113. A roller 114 is installed in the fixed platform 112. The roller 114 is installed in the fixed platform 112 in the form of a pin 115. When the operator pulls the handle mechanism 10, the pulley structure 11 installed below the first clamping plate 1 and above the second clamping plate 2 will be pulled in the same direction as the handle mechanism 10.
[0038] In the specific implementation process, such as Figure 4 The insertion rod 105 and the insertion hole 1010 shown are connected by a snap-fit mechanism.
[0039] It should be noted that the insertion rod 105 and the insertion hole 1010 are connected by a snap-fit. When the first clamping plate 1 and the second clamping plate 2 are rotated and closed with the first clamping plate 1 by the hinge 3, in order to prevent the first clamping plate 1 and the second clamping plate 2 from being opened by external force, the insertion rod 105 installed on the surface of the first pulling rod 103 and the insertion hole 1010 opened on the surface of the second pulling rod 108 are connected by a snap-fit.
[0040] In the specific implementation process, such as Figure 1 The first ball bearing 102, the second ball bearing 107, and the third ball bearing 113 shown can all rotate 360 degrees.
[0041] It should be noted that the first ball 102, the second ball 107, and the third ball 113 can all rotate 360 degrees.
[0042] In the specific implementation process, such as Figure 1 The pulley structure 11 can be pulled by the handle mechanism 10 as shown.
[0043] It should be noted that the pulley structure 11 can be pulled by the handle mechanism 10.
[0044] The working principle of this embodiment is as follows: In specific use, when it is necessary to position the pipeline, the worker places the pipeline into the first arc-shaped groove 4. The elastic element 52 and the arc-shaped block 53 in the third arc-shaped groove 51 within the first arc-shaped groove 4 will exert a reaction force on the pipeline. Then, the second clamping plate 2 and the first clamping plate 1 are rotated and closed by the hinge 3 to achieve the effect of positioning the pipeline. After the worker positions the pipeline through the clamping structure 5, in order to avoid the worker frequently changing the welding position when performing fillet welding between the overhead pipeline and the electrofusion sleeve, the first pull rod 103 installed on the surface of the second fixed plate 9 and the second pull rod 108 installed on the surface of the first fixed plate 8 are used. The pulley structure 11 installed below the first clamping plate 1 and above the second clamping plate 2 can be pulled by the personnel, thereby pulling the entire device. This avoids the need for the staff to frequently change the welding position when performing fillet welding between the overhead pipeline and the electrothermal welding sleeve, thus improving work efficiency and reducing working time. The staff can pull the device by pulling the handle mechanism 10. The pulley structure 11 installed below the first clamping plate 1 and above the second clamping plate 2 will be pulled in the same direction as the handle mechanism 10. In order to prevent the first clamping plate 1 and the second clamping plate 2 from being opened by external force, the insertion rod 105 installed on the surface of the first pulling rod 103 and the insertion hole 1010 opened on the surface of the second pulling rod 108 are connected by a snap-fit.
