Description

[0034] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0035] Example: Figure 1-Figure 14 As shown, the present invention provides a technical solution for a pipeline welding positioning device for pipeline construction.

[0036] Specifically, in the multi-directional positioning structure 2 provided in the present application, a plurality of threaded holes 22 are provided on the outer side of the mounting frame 21, and the plurality of threaded holes 22 meet the requirements for installing the mounting frame 21 on the vehicle. The mounting frame 21 can be installed on the vehicle by bolts matching the threaded holes 22, so that the multi-directional positioning structure 2 is installed on the vehicle. A forward and reverse motor 23 is fixedly inserted on the mounting frame 21, and a mounting frame 25 is fixedly sleeved on the outer side of a transmission shaft 24 fixedly installed at the output end of the forward and reverse motor 23 to control the forward and reverse motor 23 to work forward or reverse. The forward and reverse motor 23 drives the mounting frame 25 and the mounting frame 3 26 set at one end of the mounting frame 25 to rotate through the transmission shaft 24 fixed at the output end, so as to adjust the angle of the mounting frame 3 26.

[0037] Three mounting frames four 27 are fixedly connected to the bottom of the mounting frame three 26. A hydraulic cylinder 29 is arranged inside the mounting frame four 27 in the middle, and telescopic rods 28 are arranged inside the other two mounting frames four 27. The telescopic hydraulic cylinder 29 and the telescopic rod 28 are respectively fixedly connected to the mounting frame four 27 and the mounting frame two 25 at both ends. The spacing between the mounting frame three 26 and the mounting frame two 25 can be controlled by controlling the hydraulic cylinder 29 to extend or contract. The distance and angle between the mounting frame three 26 and the vehicle can be adjusted by cooperating with the hydraulic cylinder 29 and the forward and reverse motor one 23.

[0038] Mounting frames 5 210 are fixedly connected to both sides of the top of the mounting frame 3 26, and a winding frame 213 is rotatably connected between the two mounting frames 5 210. The winding frame 213 can rotate, and a mounting plate 4 211 is fixedly connected to one side of one of the mounting frames 5 210. A forward and reverse motor 212 is fixedly installed on the top of the mounting plate 4 211. The output end of the forward and reverse motor 212 is connected to the winding frame 213. The forward and reverse motor 212 is controlled to work forward or reverse, so that the winding frame 213 rotates clockwise or counterclockwise, and the winding frame 213 rewinds or unwinds the rubber member 212 fixedly installed. 7. Mounting plates 5 214 are provided on both sides of the rubber member 217. Two long shaft members 4 215 are rotatably connected between the two mounting plates 5 214. The rubber member 217 passes through between the two long shaft members 4 215. A long groove 216 is provided on the top of the mounting frame 3 26 away from the mounting frame 1 21. One end of the rubber member 217 passes through the long groove 216 and is fixedly connected to the two rubber members 1 112. The rubber member 217 is supported downward by two rotatable long shaft members 4 215. As the rubber member 217 is wound and unwound, the pipeline adaptive structure 1 installed at the bottom end of the rubber member 217 moves up or down.

[0039] The specific use method of the pipe fitting hoisting and positioning device composed of the pipeline adaptive structure 1, the welding rod clamping structure 3 and the transmission structure 4 in this application is as follows:

[0040] Embodiment 1:

[0041] The staff pulls the two arc frames 11 in the pipeline adaptive structure 1, so that the two arc frames 11 move from both sides of the pipe fitting to the bottom of the pipe fitting respectively, and then aligns the two arc frames 11 to control the overall position of the pipeline adaptive structure 1 so that the two rubber parts 112 are located on the outside near the middle of the pipe fitting;

[0042] Then operate the handle 17 in the pull-out frame, and two plug-in rods 15 and two plug-in rods 16 are fixedly connected to one side of the handle 17. One side of the two arc-shaped frames 11 is provided with a plug-in groove 13 and a plug-in groove 14. Align the plug-in rod 15 with the corresponding plug-in groove 13, align the plug-in rod 2 16 with the corresponding plug-in groove 2 14, and finally push the handle 17 to insert the plug-in rod 15 into the plug-in groove 13, and insert the plug-in rod 2 16 into the plug-in groove 2 14. Under the action of the pull-out frame, the two arc-shaped frames 11 are restricted to be installed together. At this time, the two arc-shaped frames 11 form a lower arc-shaped frame to support the bottom of the pipe fitting.

[0043] Then, the multi-directional position control structure 2 is controlled to work, so that the rubber member 217 in the multi-directional position control structure 2 is rolled up; because the two sides of the arc frame 110 are provided with reserved grooves 111, one end inserted in the reserved grooves 111 is fixedly connected to the arc frame 110, and a direction-changing group is arranged on the outer side of each rubber member 112;

[0044] Both ends of the long shaft member 19 in the direction-changing assembly are rotatably connected with a mounting plate 18, a reserved groove 12 is provided on one side of the top of the arc frame 11, the mounting plate 18 is arranged inside the reserved groove 12 and fixedly connected to the arc frame 11, the long shaft member 19 and the two mounting plates 18 form a direction-changing frame inside the reserved groove 12, and one end of the rubber member 112 passes through the inside of the direction-changing frame and moves toward the top of the arc frame 110;

[0045] The two mounting plates 2 113 and the two mounting plates 3 115 in the direction-changing assembly are fixedly mounted on the top of the arc frame 2 110. The two mounting plates 2 113 are rotatably connected with two long shaft members 2 114. The two mounting plates 3 115 are rotatably connected with two long shaft members 3 116. One end of the rubber member 1 112 passes through the two long shaft members 2 114 and the two long shaft members 3 116 in sequence and is fixedly connected with the rubber member 2 217. Therefore, when the rubber member 2 217 is rolled up and moved upward, the rubber member 2 The second 217 applies an upward force to the two rubber parts 112. Under the action of the two rotatable long axis parts 3 116, the two long axis parts 2 114 and the long axis part 19, the upward force of the rubber part 112 is converted into a downward force and then acts on the arc frame 2 110, and the rubber part 112 applies an upward force to the lower arc frame through the long axis part 19. At this time, the lower arc frame is set at the bottom of the pipe, so the lower arc frame moves up and is close to the pipe, and the arc frame 2 110 moves down and is close to the pipe.

[0046] When the second arc frame 110 and the lower arc frame are both in close contact with the pipe fitting, the second arc frame 110 and the lower arc frame move upward as a whole under the weight of the pipe fitting. During this process, the second arc frame 110 is in a state of conflict with the pipe fitting under the weight of the pipe fitting. At the same time, the two rubber members 112 are tightened and fit with the outer wall of the pipe fitting. Under the action of the second arc frame 110, the lower arc frame and the two rubber members 112, most of the outer part of the structure in the pipe fitting is subjected to force, providing a positioning structure that is easy to operate and can clamp and fix the pipe fitting in multiple directions, and can automatically adapt to the clamping and lifting work of pipes with different outer diameters, thereby ensuring the stability of the pipe fitting clamping.

[0047] The multi-directional positioning structure 2 is made to work to lift the pipeline adaptive structure 1. After the pipe fittings clamped and fixed by the pipeline adaptive structure 1 are lifted to a suitable height, the multi-directional positioning structure 2 is controlled to stop working, and then the vehicle installed by the multi-directional positioning structure 2 is controlled to move slowly, and the pipeline is lifted to the processing position and then lowered. When the pipe fittings fall to the installation position, the weight of the pipe fittings acts on the facilities of the pipe fitting station, and then the pulling frame is pulled away from the two arc frames 11, and the arc frame 11 can be taken out from both sides of the pipe fittings, so that the pipeline adaptive structure 1 is separated from the pipe fittings.

[0048] Embodiment 2:

[0049] When the pipe fitting is relatively short, the pipeline adaptive structure 1 can be installed on the outside of the pipe fitting near one end; then, according to the technical solution provided in the first embodiment, one end of the pipe fitting is hoisted near the construction position. Since the rubber member 112 and the rubber member 217 are made of rubber and have a certain deformation ability, when the pipe fitting is relatively short, light and suspended in the air, the position of the pipe fitting can be fine-tuned by hand.

[0050] The welding rod clamping structure 3 of the present application is provided with four hexagonal slots 34, two of which are respectively opened on the two arc-shaped frames 11, and the other two hexagonal slots 34 are opened on the arc-shaped frame 2 110. The four hexagonal slots 34 are all inserted with plug-in rods 32, two of which are fixedly connected to the upper clamping plate 31, and the other two plug-in rods 3 32 are respectively fixedly connected to the two lower clamping plates 33. Under the action of the four plug-in rods 3 32, the upper clamping plate 31 and the arc-shaped frame 2 110 move synchronously, and the two lower clamping plates 33 move with the two arc-shaped frames 11;

[0051] After one end of the pipe fitting is close to one end of the installed pipe fitting, the upper clamping plate 31 and the two lower clamping plates 33 are pulled so that the upper clamping plate 31 and the two lower clamping plates 33 form an external frame, and the external frame is located on one side of one end of the pipe fitting. At this time, the pipeline adaptive structure 1 and the pipe fitting clamped by the pipeline adaptive structure 1 are manually fine-tuned, and the external frame is pushed and sleeved to the outside of the installed pipe fitting, and then the suspended pipe fitting is pushed. Under the action of the welding rod clamping structure 3, one end of the pipe fitting moves to dock and fit with one end of the installed pipe fitting, thereby completing the preparation work for fixed alignment between the pipe fitting and the installed pipe fitting.

[0052] Afterwards, the staff used supporting facilities to support the pipe fittings so that the relative position between the pipe fittings and the installed pipe fittings was fixed.

[0053] An upper clamping groove 35 is provided on one side of the upper clamping plate 31, and lower clamping grooves 37 are provided on the sides of the two lower clamping plates 33 that are close to each other. Deformable rubber pads 36 are provided on both sides of the upper clamping groove 35 and on one side of the two lower clamping grooves 37. The rubber pads 36 provided in the upper clamping groove 35 are fixedly connected to the upper clamping plate 31, and the rubber pads 36 provided in the lower clamping groove 37 are fixedly connected to the lower clamping plate 33, and the rubber pads 36 cannot move.

[0054] A degradable plastic plate 39 is integrally formed on one side of the top of the arc-shaped welding rod 38. After the multi-directional control structure 2 and the pipeline adaptive structure 1 cooperate to lift the pipe fitting to a suitable height or lift the pipe fitting to the vicinity of the construction location, the two welding rods 38 can be respectively sleeved on the bottom and top of the outer side of the pipe fitting, and then the degradable plastic plate 39 is pushed into the rubber pad 36 or the two lower clamping grooves 37. The rubber pad 36 is deformed to clamp the degradable plastic plate 39 so that the welding rod 38 is installed on the pipe fitting. The two welding rods 38 move synchronously with the upper clamping plate 31 and the lower clamping plate 33, and the position of the welding rod clamping structure 3 is adjusted so that the two welding rods 38 move to the pipe fitting and the already The gap between the two is covered on the outside of the connection of the installed pipe fitting, and then the welding rod 38 is heated and melted with a welding gun, so that the pipe fitting and the installed pipe fitting can be welded and installed together, and an upper welding rod clamping structure 3 is set on one side of the multi-directional control structure 2, which can not only complete the movement of one end of the pipe fitting and the docking and fitting with one end of the installed pipe fitting, and complete the fixed alignment between the pipe fitting and the installed pipe fitting, but also achieve the effect of pre-fixing the welding rod 38 to the outside of the contact position between the pipe fitting and the installed pipe fitting, so as to avoid the situation where the staff restricts the suspended pipe fitting while holding the restricting welding rod 38 and operating the welding gun for construction, thereby reducing the labor cost investment required for welding the two pipe fittings.

[0055] Even if the degradable plastic plate 39 is not recycled, it will degrade into the soil and will not cause pollution.

[0056] Finally, the multi-directional position control structure 2 is controlled to work and lower the pipeline adaptive structure 1, and the pipeline adaptive structure 1 is removed from the outside of the pipe fitting, so that the pipe fitting and the installed pipe fitting can be fixed.

[0057] Embodiment three:

[0058] When the pipe fitting is heavy as a whole and needs to be fixed and lifted from the outside of the pipe fitting near the end, the pipeline adaptive structure 1 is set on the outside of the pipe fitting at one end;

[0059] Then, insert one end of the prepared hexagonal wrench into the inner hexagonal nut 244 fixedly connected to one end of the transmission shaft 245, and rotate the hexagonal wrench, so that the inner hexagonal nut 244 drives the transmission shaft 245 and the transmission gear 46 fixedly sleeved on the outer side of the transmission shaft 245 to rotate, and a mounting plate 6 411 is fixedly connected between the two mounting plates 3 115 on the same side, and the transmission shaft 245 is rotationally connected to one of the mounting plates 6 411, so the transmission shaft 245 rotates on one side of the mounting plate 6 411;

[0060] The two rotating short rods 48 rotatably connected to the two mounting plates 6 411 are fixedly connected with driven gears 47 on the outside. The transmission gear 46 is arranged between the two driven gears 47 and meshes with the two driven gears 47. The rotating transmission gear 46 drives the two rotating short rods 48 to rotate through the two driven gears 47. A plurality of pull wires 49 are fixedly connected between the transmission frame 410 sleeved on the outside of the rubber member 112 and the adjacent rotating short rods 48. The rotating rotating short rods 48 reel in the pull wires 49, and the pull wires 49 drive the transmission frame 410 to move. Under the premise that the rubber member 217 is not unwound, the transmission frame 410 is driven by the pull wires 49 to move toward the rotating short rods 48. The outer side of the rubber member 112 is supported and limited by the two long shaft members 2 114 and the two long shaft members 3 116. Therefore, the two arc frames 2 110 and the rubber member 1 112 drive the arc frame 11 to move upward through the long shaft member 19.

[0061] When the arc frame 110 and the lower arc frame composed of the two arc frames 11 are in close contact with the pipe fittings, force is continuously applied to the inner hexagonal nut 44 to generate a certain friction force between the two rubber pieces 112, the lower arc frame, the arc frame 110 and the pipe fittings, and the inner hexagonal nut 43 fixedly installed at the input end of the brake 42 is operated to rotate clockwise, and the brake 42 is sleeved on the outer side of the transmission shaft 45. The working brake 42 brakes the transmission shaft 45, so that the transmission shaft The rotation of the second 45 is restricted by the brake 42. The brake 42 has a bent plate 41 fixedly connected to the adjacent mounting plate three 115 on both sides. The relative positions of the brake 42, the mounting plate three 115 and the arc frame two 110 fixedly connected to the mounting plate three 115 remain unchanged. The transmission shaft two 45 cannot rotate. The rubber member one 112, the arc frame two 110 and the lower arc frame all maintain the clamping of the pipe fitting as a whole. The relative position between the lower arc frame and the arc frame two 110 cannot change.

[0062] Then, the multi-directional positioning structure 2 is controlled to work and reel in the rubber member 217, so that the rubber member 112, the arc frame 2 110 and the lower arc frame are moved upward as a whole, and the pipe fitting is driven to move upward. Under the action of the transmission structure 4, even if the pipeline adaptive structure 1 is installed at one end of the outer side of the pipe fitting, after the tilting force generated by the pipe fitting acts on the arc frame 2 110 and the lower arc frame, the relative position between the arc frame 2 110 and the lower arc frame remains unchanged, and the clamping and positioning effect on the pipe fitting can still be maintained.

[0063] The present application, through the pipeline adaptive structure 1 and the welding rod clamping structure 3 and the transmission structure 4 installed on the pipeline adaptive structure 1, can meet the needs of lifting pipes of different lengths and different positions of pipes as lifting points, thereby ensuring flexible and efficient lifting of pipes.

[0064] It will be apparent to those skilled in the art that the invention is not limited to the details of the exemplary embodiments described above and that the invention can be implemented in other specific forms without departing from the spirit or essential features of the invention. Therefore, the embodiments should be considered exemplary and non-limiting in all respects, and the scope of the invention is defined by the appended claims rather than the foregoing description, and it is intended that all variations falling within the meaning and scope of the equivalent elements of the claims be included in the invention.
