Description

Technical Field

[0001] The invention relates to the technical field of hoisting and positioning, in particular to a pipeline welding positioning device for pipeline construction. Background Art

[0002] The oil pipeline (also called pipeline, pipeline) is composed of oil pipes and their accessories, and is equipped with corresponding oil pump units according to the needs of the process flow. It is designed and installed into a complete pipeline system to complete the tasks of oil loading and unloading and transfer.

[0003] At present, for pre-buried oil pipelines, a trench of a certain depth is first dug on the ground by an excavator, and the oil pipeline is moved into the trench by means of straps and cranes.

[0004] However, after the oil pipeline is moved, the straps need to be removed and tied to the next pipeline. The straps are fixed by tying knots. Dead knots are difficult to untie and loose knots pose a safety hazard. The lifting belts themselves are prone to wrinkles and are difficult to fit completely with the surface of the pipe. Unbalanced force during the lifting of the pipe increases the possibility of shaking, which requires workers to not only limit the welding rods during welding, but also pay attention to the position of the pipeline and operate the welding gun, affecting the stability and safety of welding.

[0016] Compared with the prior art, the present invention has the following beneficial effects:

[0017] 1. The position of the welding rod clamping structure in the present application enables the two welding rods to move to the outside of the connection between the pipe fitting and the installed pipe fitting to cover the gap between the two. Then, the welding rod is heated and melted using a welding gun, and the pipe fitting and the installed pipe fitting can be welded and installed together. The welding rod clamping structure is arranged on one side of the multi-directional control structure, which can not only complete the movement of one end of the pipe fitting to connect and fit 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 to the outside of the contact position between the pipe fitting and the installed pipe, avoiding the situation where the staff restricts the suspended pipe fitting while holding the restricting welding rod and operating the welding gun for construction, thereby reducing the labor cost investment required for welding the two pipe fittings.

[0018] 2. When the present application is used, after the arc frame 2 and the lower arc frame are both in close contact with the pipe fittings, the arc frame 2 and the lower arc frame move upward as a whole under the weight of the pipe fittings. During this process, the arc frame 2 is in a state of conflict with the pipe fittings under the weight of the pipe fittings. At the same time, the two rubber parts are tightened and fit with the outer wall of the pipe fittings. Under the action of the arc frame 2, the lower arc frame and the two rubber parts, 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 fittings 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.

Detailed implementation manners

[0034] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts belong to the scope of protection of the present invention.

[0035] Embodiment: As Figures 1 - 14 shown, the present invention provides a technical solution for a pipe welding positioning device for pipe 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 one 21. The plurality of threaded holes 22 meet the installation requirements of the mounting frame one 21 and the vehicle. The mounting frame one 21 can be installed on the vehicle through bolts matching the threaded holes 22, so that the multi-directional positioning structure 2 is installed on the vehicle. A forward and reverse motor one 23 is fixedly inserted on the mounting frame one 21. A mounting frame two 25 is fixedly sleeved on the outer side of the transmission shaft one 24 fixedly installed at the output end of the forward and reverse motor one 23. By controlling the forward rotation or reverse rotation of the forward and reverse motor one 23, the forward and reverse motor one 23 drives the mounting frame two 25 and the mounting frame three 26 provided at one end of the mounting frame two 25 to rotate through the transmission shaft one 24 fixed at the output end, and the angle of the mounting frame three 26 is adjusted.

[0037] Three mounting frames four 27 are fixedly connected to the bottom of the mounting frame three 26. A hydraulic cylinder 29 is provided inside the middle mounting frame four 27, and telescopic rods 28 are provided inside the other two mounting frames four 27. The extendable hydraulic cylinder 29 and the telescopic rods 28 are fixedly connected to the mounting frame four 27 and the mounting frame two 25 respectively at both ends. By controlling the hydraulic cylinder 29 to work for extension or contraction, the distance between the mounting frame three 26 and the mounting frame two 25 can be controlled. Through the cooperation of the hydraulic cylinder 29 and the forward and reverse motor one 23, the distance and angle between the mounting frame three 26 and the vehicle can be adjusted.

[0038] On both sides of the top of the third mounting bracket 26, fifth mounting brackets 210 are fixedly connected. A winding frame 213 is rotatably connected between the two fifth mounting brackets 210, and the winding frame 213 can rotate. On one side of one of the fifth mounting brackets 210, a fourth mounting plate 211 is fixedly connected. A forward and reverse motor two 212 is fixedly installed on the top of the fourth mounting plate 211. The output end of the forward and reverse motor two 212 is operatively connected to the winding frame 213. By controlling the forward or reverse operation of the forward and reverse motor two 212, the winding frame 213 can rotate clockwise or counterclockwise. The winding frame 213 winds or unwinds a fixedly installed second rubber part 217. On both sides of the second rubber part 217, fifth mounting plates 214 are provided. Two long shaft parts four 215 are rotatably connected between the two fifth mounting plates 214. The second rubber part 217 passes through between the two long shaft parts four 215. And a long groove 216 is formed on the top of the third mounting bracket 26 away from the first mounting bracket 21. One end of the second rubber part 217 penetrates through the long groove 216 and is fixedly connected to the two first rubber parts 112. Under the support of the two rotatable long shaft parts four 215, as the second rubber part 217 is wound and unwound, the pipe adaptor structure 1 installed at the bottom end of the second rubber part 217 moves up or down.

[0039] The specific usage method of the pipe hoisting and positioning device composed of the pipe adaptor structure 1, the electrode clamping structure 3 and the transmission structure 4 in this application is as follows:

[0040] Example 1:

[0041] The staff pulls the two first arc-shaped frames 11 in the pipe adaptor structure 1, so that the two first arc-shaped frames 11 move from both sides of the pipe fitting to the bottom of the pipe fitting respectively, and then align the two first arc-shaped frames 11, and control the overall position of the pipe adaptor structure 1, so that the two first rubber parts 112 are located outside the position close to the middle part of the pipe fitting.

[0042] Subsequently, the handle 17 in the draw frame is operated. Two first inserting rods 15 and two second inserting rods 16 are fixedly connected to one side of the handle 17. Inserting grooves one 13 and inserting grooves two 14 are formed on one side of each of the two first arc-shaped frames 11. Align the first inserting rod 15 with the corresponding inserting groove one 13, and align the second inserting rod 16 with the corresponding inserting groove two 14. Finally, push the handle 17, so that the first inserting rod 15 is inserted into the internal of the inserting groove one 13, and the second inserting rod 16 is inserted into the internal of the inserting groove two 14. Under the action of the draw frame, the two first arc-shaped frames 11 are restricted to be installed together. At this time, the two first arc-shaped frames 11 form a lower arc-shaped frame to support the bottom of the pipe fitting.

[0043] Subsequently, control the multi-directional position control structure 2 to work, so that the second rubber part 217 in the multi-directional position control structure 2 is wound; Since reserved grooves two 111 are formed on both sides of the second arc-shaped frame 110, one end inserted on the reserved groove two 111 is fixedly connected to the second arc-shaped frame 110, and a direction changing group is arranged on the outside of each first rubber part 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 pipe adaptor structure 1 can be installed on the outer side of the pipe fitting near one end; then, according to the technical solution provided in the first embodiment above, one end of the pipe fitting is hoisted near the construction position. Since the first rubber part 112 and the second rubber part 217 are made of rubber and have a certain deformation ability, when the pipe fitting is short, light and in a suspended state, the position of the pipe fitting can be finely adjusted by hand.

[0050] In the electrode clamping structure 3 of the present application, four hexagonal grooves 34 are provided. Two of the hexagonal grooves 34 are respectively formed on two first arc-shaped frames 11, and the remaining two hexagonal grooves 34 are both formed on the second arc-shaped frame 110. Plugging rods three 32 are inserted into the four hexagonal grooves 34. Two of the plugging rods three 32 are fixedly connected to the upper clamping plate 31, and the other two plugging rods three 32 are respectively fixedly connected to the two lower clamping plates 33. Under the action of the four plugging rods three 32, the upper clamping plate 31 and the second arc-shaped frame 110 move synchronously, and the two lower clamping plates 33 and the two first arc-shaped frames 11 move;

[0051] After one end of the pipe fitting is close to one end of the already installed pipe fitting, the upper clamping plate 31 and the two lower clamping plates 33 are pulled to form an external frame, and the external frame is located on one side of one end of the pipe fitting. At this time, the pipe adaptor structure 1 and the pipe fitting clamped by the pipe adaptor structure 1 are finely adjusted manually. The external frame is pushed and sleeved on the outer side of the already installed pipe fitting, and then the suspended pipe fitting is pushed. Under the action of the electrode clamping structure 3, one end of the pipe fitting moves and is butted and fitted with one end of the already installed pipe fitting, and the preparatory work for fixing and aligning the pipe fitting and the already installed pipe fitting can be completed.

[0052] Subsequently, the staff uses a support facility to support the pipe fitting so that the relative position between the pipe fitting and the already installed pipe fitting is fixed.

[0053] Moreover, an upper clamping groove 35 is formed on one side of the upper clamping plate 31, and lower clamping grooves 37 are formed on the mutually close sides of the two lower clamping plates 33. Deformable rubber pads 36 are arranged on both sides inside the upper clamping groove 35 and on one side of the two lower clamping grooves 37. The rubber pad 36 arranged inside the upper clamping groove 35 is fixedly connected to the upper clamping plate 31, and the rubber pad 36 arranged inside the lower clamping groove 37 is fixedly connected to the lower clamping plate 33. The position of the rubber pad 36 cannot move;

[0054] On one side of the top of the arc-shaped electrode 38, a degradable plastic plate 39 is integrally formed. After the multi-directional position control structure 2 and the pipe self-adaptive structure 1 cooperate to lift the pipe fitting to an appropriate height or lift the pipe fitting to the vicinity of the construction position, the two electrodes 38 can be respectively sleeved on the outer bottom and top of the pipe fitting. Subsequently, the degradable plastic plate 39 is pushed into the rubber pad 36 or the two lower clamping grooves 37. The rubber pad 36 deforms to clamp the degradable plastic plate 39, so that the electrode 38 is installed on the pipe fitting. The two electrodes 38 move synchronously with the upper clamping plate 31 and the lower clamping plate 33 to adjust the position of the electrode clamping structure 3, so that the two electrodes 38 move to the outside of the connection between the pipe fitting and the already installed pipe fitting to cover the gap between them. Subsequently, a welding torch is used to heat and melt the electrode 38, and the pipe fitting and the already installed pipe fitting can be welded and installed together. By arranging the upper electrode clamping structure 3 on one side of the multi-directional position control structure 2, not only can the movement of one end of the pipe fitting be completed to butt and fit with one end of the already installed pipe fitting, and the work of fixing and aligning between the pipe fitting and the already installed pipe fitting be completed, but also the effect of pre-fixing the electrode 38 to the outside of the contact position between the pipe fitting and the already installed pipe fitting can be achieved, avoiding the situation where the staff restricts the suspended pipe fitting while holding and restricting the electrode 38 and operating the welding torch for construction, and 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, control the multi-directional position control structure 2 to work and lower the pipe self-adaptive structure 1, and remove the pipe self-adaptive structure 1 from the outside of the pipe fitting, and then the fixing work of the pipe fitting and the already installed pipe fitting can be carried out.

[0057] Embodiment 3:

[0058] When the overall weight of the pipe fitting is heavy and it is necessary to fix and lift it from the outside of the pipe fitting near the end; the pipe self-adaptive structure 1 is sleeved on one end position of the outside of the pipe fitting;

[0059] Subsequently, one end of a prepared hexagonal wrench is inserted into the internal hexagonal nut 44 fixedly connected to one end of the transmission shaft 2 45 and the hexagonal wrench is rotated, so that the internal hexagonal nut 44 drives the transmission shaft 2 45 and the transmission gear 46 fixedly sleeved on the outside of the transmission shaft 2 45 to rotate. And a mounting plate 6 411 is fixedly connected between the two mounting plates 3 115 on the same side. The transmission shaft 2 45 is rotatably connected to one of the mounting plates 6 411. Therefore, the transmission shaft 2 45 rotates on one side of the mounting plate 6 411;

[0060] On the outer sides of two rotating short rods 48 rotatably connected to two mounting plates 411, driven gears 47 are fixedly connected. A driving gear 46 is arranged between the two driven gears 47 and meshes with the two driven gears 47. The rotating driving gear 46 drives the two rotating short rods 48 to rotate through the two driven gears 47. A plurality of guy wires 49 are fixedly connected between a transmission frame 410 sleeved on the outer side of a first rubber part 112 and an adjacent rotating short rod 48. The rotating short rod 48 winds up the guy wire 49, and the guy wire 49 drives the transmission frame 410 to move. On the premise that the second rubber part 217 is not unwound, the transmission frame 410 is driven by the guy wire 49 to move towards the rotating short rod 48. The outer side of the first rubber part 112 is also supported and limited by two second long shaft parts 114 and two third long shaft parts 116. Therefore, the two arc-shaped frames 110 of the first rubber part 112 drive the arc-shaped frame 11 to move upwards through the first long shaft part 19.

[0061] When the lower arc-shaped frame formed by the arc-shaped frame 110 and the two arc-shaped frames 11 is in close contact with the pipe fitting, continue to apply force to the second hexagon nut 44, so that a certain frictional force is generated between the two first rubber parts 112, the lower arc-shaped frame and the arc-shaped frame 110 and the pipe fitting. Then, rotate the first hexagon nut 43 fixedly installed at the input end of the brake 42 clockwise. The brake 42 is also sleeved on the outer side of the second transmission shaft 45. The working brake 42 brakes the second transmission shaft 45, restricting the rotation of the second transmission shaft 45. Bent plates 41 are fixedly connected between both sides of the brake 42 and the adjacent third mounting plate 115. The relative positions between the brake 42, the third mounting plate 115 and the arc-shaped frame 110 fixedly connected to the third mounting plate 115 remain unchanged. The second transmission shaft 45 cannot rotate. The first rubber parts 112, the arc-shaped frame 110 and the lower arc-shaped frame all maintain the overall clamping of the pipe fitting, and the relative positions between the lower arc-shaped frame and the arc-shaped frame 110 cannot change.

[0062] Subsequently, control the multi-directional position control structure 2 to work and wind up the second rubber part 217, so that the first rubber part 112, the arc-shaped frame 110 and the lower arc-shaped frame move upwards as a whole, driving the pipe fitting to move upwards. Under the action of the transmission structure 4, even if the pipe adaptor structure 1 is installed at one end outside the pipe fitting, after the tilting force generated by the pipe fitting acts on the arc-shaped frame 110 and the lower arc-shaped frame, the relative positions between the arc-shaped frame 110 and the lower arc-shaped frame remain unchanged, and the clamping and positioning function for the pipe fitting can still be maintained.

[0063] Through the pipe adaptor structure 1, the electrode clamping structure 3 and the transmission structure 4 installed on the pipe adaptor structure 1 in this application, the needs for hoisting pipe fittings of different lengths and using different positions of the pipe fittings as hoisting points can be met, ensuring the flexible and efficient hoisting of pipe fittings.
