Description

TECHNICAL FIELD

[0001] The application relates to the technical field of reservoir expansion metal structure construction, in particular to a steel lining welding device. BACKGROUND

[0002] When a reservoir is expanded, a larger chamber is dug on one side of the dam as a spillway air hole, and a steel lining structure is usually installed on the inner circumferential wall of the spillway air hole to increase the strength of the spillway air hole. The steel lining structure is assembled by splicing a plurality of single steel lining frames, and each single steel lining frame comprises four large-sized face plates and a plurality of reinforcing rib plates. The four face plates are spliced with each other and welded to form a rectangular steel plate frame, and the plurality of reinforcing rib plates are welded to the outer walls of the four face plates to increase the strength of the four face plates.

[0003] In order to reduce the influence of hoisting and transportation on the splicing quality of the single steel lining frame, the face plates and the reinforcing rib plates are directly transported to the spillway air hole construction site for manual welding after being inspected and qualified. If cold and hot welding are alternated for multiple times (i.e. the welding is stopped for a short time and then continued) during the welding, the welding quality will be affected. Therefore, in order to ensure the welding quality, the workers need to try their best to weld once at a time to form a continuous and neat weld when welding the adjacent two face plates. However, due to the large size of the face plates, the welding time of a weld is relatively long, so the workers are prone to hand tremor at the half way of the welding, which causes slight deviation of the weld, and further affects the welding quality of the steel lining. CONTENT OF THE UTILITY MODEL

[0004] In order to improve the welding quality of the steel lining, the application provides a steel lining welding device.

[0005] The steel lining welding device provided by the application adopts the following technical scheme:

[0006] The steel lining welding device comprises a base plate, a horizontal directional assembly installed on the base plate, a vertical directional assembly installed on the horizontal directional assembly, and a welding tongs installed on the vertical directional assembly, the vertical directional assembly slides on the horizontal directional assembly in a horizontal direction, the welding tongs is rotatably installed on the vertical directional assembly, and the welding tongs slides on the vertical directional assembly in a vertical direction.

[0007] Preferably, the horizontal directional assembly comprises a support rod and a horizontal guide rail set, the support rod is fixedly arranged on the base plate, the horizontal guide rail set is installed on the side wall of the support rod, and one end of the horizontal guide rail set extends in a horizontal direction and protrudes from the base plate.

[0008] Preferably, the vertical orientation assembly comprises a vertical sliding plate and a vertical guide rail set installed on the vertical sliding plate for directional sliding of the welding tongs.

[0009] Preferably, the vertical orientation assembly further comprises a cantilever installed on the vertical guide rail set and sliding along the vertical direction on the vertical guide rail set, and the welding tongs are rotatably installed on the cantilever.

[0010] Preferably, an end of the cantilever away from the vertical guide rail set protrudes from the base plate, and the welding tongs are located at the end of the cantilever away from the vertical guide rail set.

[0011] Preferably, a sleeve ring is rotatably connected to the cantilever, the welding tongs are inserted into the sleeve ring, and a locking bolt is threadedly installed on the outer wall of the sleeve ring to limit the welding tongs in the sleeve ring.

[0012] Preferably, an end of the horizontal guide rail set is provided with a horizontal limiting plate to block the movement of the vertical sliding plate, and an end of the horizontal guide rail set away from the horizontal limiting plate is provided with a horizontal limiting bolt to block the movement of the vertical sliding plate, and the horizontal limiting bolt is threadedly installed on the support rod.

[0013] Preferably, a vertical limiting plate is arranged below the vertical guide rail set to block the movement of the cantilever, and the vertical limiting plate is fixedly installed on the vertical sliding plate.

[0014] Preferably, a universal wheel with a brake locking function is arranged at the bottom of the base plate.

[0015] Preferably, an electric welding machine is placed on the top of the base plate.

[0016] In summary, the present application has at least one of the following beneficial technical effects:

[0017] 1. When welding the steel lining, the welding device is moved to the welding position and adjusted to align the electrode on the welding tongs with the welding seam. The welding tongs are limited by the vertical guide rail set and can move straight along the vertical direction during welding. The electrode will be consumed during welding. At this time, the operator can make the welding tongs move along the vertical direction while being directional to the welding seam under the limitation of the horizontal guide rail set, so that the electrode can always abut against the steel lining panel, thereby ensuring the neatness of the welding seam and improving the welding quality.

[0018] 2. Since different operators hold the welding tongs at different angles during welding, the welding tongs are rotatably installed on the cantilever through the sleeve ring, so that the angle of the welding tongs can be adjusted, thereby facilitating different users to adjust the holding angle suitable for themselves.

[0019] 3. Since the vertical guide rail group has a certain distance from the ground under the action of the base plate and the universal wheel, the welding tongs are not easy to weld the position on the sleeve ring, and the welding tongs are limited on the sleeve ring by the set screw, so that the welding tongs are more convenient to disassemble, and then the welding tongs can be disassembled when welding the position;

[0020] 4. The welding device is more convenient to move through the universal wheel, and the universal wheel itself has the function of brake locking. In the welding process, the universal wheel is locked to make the welding device not easy to move. In addition, the electric welding machine is placed on the base plate, so that the movement of the electric welding machine is also more convenient, and the electric welding machine can play the role of counterweight, so that the welding device is not easy to fall due to the one end of the horizontal guide rail group protruding from the base plate.

DETAILED DESCRIPTION

[0025] The following will be described in detail in combination with the accompanying Figures 1-3 The application will be further described in detail.

[0026] The embodiment of the application discloses a steel lining welding device. Referring to Figure 1The steel lining welding device comprises a base plate 1, a horizontal directional assembly 2, a vertical directional assembly 3 and a welding tongs 4. The horizontal directional assembly 2 is installed on the top of the base plate 1, the vertical directional assembly 3 is installed on the horizontal directional assembly 2, and the vertical directional assembly 3 can move along the horizontal direction on the horizontal directional assembly 2 to approach or move away from the steel lining. The welding tongs 4 can move along the vertical direction on the vertical directional assembly 3, and the welding tongs 4 can stably move along the vertical direction to form a weld with high verticality and less bending when welding the steel lining.

[0027] The base plate 1 is preferably a rectangular plate, and universal wheels 11 are installed on the four corners of the bottom of the base plate 1 by bolts, so that the welding device is convenient to move. The universal wheels 11 have a brake locking function (a standard part), and the universal wheels 11 can be locked when welding the steel lining, so that the base plate 1 is not easy to move, and the welding tongs 4 are not easy to shake during welding, so that the welding quality is high.

[0028] Referring to Figure 1 , an electric welding machine 12 adapted to the welding tongs 4 is placed on the top of the base plate 1, and the electric welding machine 12 is located on one side of the horizontal directional assembly 2. Since the universal wheels 11 are installed on the bottom of the base plate 1, the electric welding machine 12 is placed on the base plate 1, so that the electric welding machine 12 does not need to be manually carried during movement, but moves together with the base plate 1, so that the movement of the electric welding machine 12 is more labor-saving and convenient.

[0029] Referring to Figure 1 and Figure 2 , the horizontal directional assembly 2 comprises a support rod 21 and a horizontal guide rail set 22, the support rod 21 is welded to the base plate 1 at the bottom, and the horizontal guide rail set 22 is installed on the support rod 21.

[0030] Referring to Figure 1 and Figure 2 , the support rod 21 comprises an integral vertical rod 211 and a horizontal rod 212. The bottom of the vertical rod 211 is welded and fixed to the base plate 1, the horizontal rod 212 is located at the top of the vertical rod 211, and the vertical rod 211 and the horizontal rod 212 are an inverted L-shaped rod. The end of the horizontal rod 212 away from the vertical rod 211 extends away from the side of the electric welding machine 12, the end of the horizontal rod 212 away from the vertical rod 211 protrudes from the base plate 1, and the horizontal guide rail set 22 is installed on the side wall of one side of the horizontal rod 212, and one end of the horizontal guide rail set 22 protrudes from the base plate 1. Thus, the base plate 1 and the steel lining can be spaced apart by a certain distance when welding the steel lining, so that the vertical directional assembly 3 can be located on the side of the base plate 1 close to the steel lining. In addition, the electric welding machine 12 is located below the side away from the horizontal rod 212 protruding from the base plate 1, which also plays a role of counterweight, so that the base plate 1 is not easy to fall over.

[0031] Referring to Figure 1With Figure 2 The transverse guide rail group 22 comprises a transverse linear guide rail 221 and a transverse sliding block 222. The extending direction of the transverse linear guide rail 221 is consistent with the extending direction of the horizontal bar 212. The transverse linear guide rail 221 protrudes from the base plate 1 along the extending direction of the transverse linear guide rail 221 away from one end of the vertical bar 211, and is fixed on the horizontal bar 212 by bolts. The transverse sliding block 222 is slidingly installed on the transverse linear guide rail 221.

[0032] Referring to Figure 1 With Figure 2 One end of the transverse linear guide rail 221 away from the vertical bar 211 is provided with a transverse limiting plate 23, which is welded on the horizontal bar 212, and the end of the transverse limiting plate 23 away from the horizontal bar 212 protrudes from the transverse linear guide rail 221, so that the transverse limiting plate 23 can block the movement of the transverse sliding block 222, so that the transverse sliding block 222 is not easy to slide off the transverse linear guide rail 221. One end of the transverse linear guide rail 221 close to the vertical bar 211 is provided with a transverse limiting bolt 24, which is threadedly detachably installed on the horizontal bar 212. The end of the transverse limiting bolt 24 away from the horizontal bar 212 also protrudes from the transverse linear guide rail 221, so that the sliding block is blocked and limited. In addition, since the transverse limiting bolt 24 is threadedly installed on the horizontal bar 212, when the transverse sliding block 222 is disassembled, the transverse limiting bolt 24 can be disassembled from the horizontal bar 212.

[0033] Referring to Figure 1 With Figure 2 The vertical orientation assembly 3 comprises a vertical sliding plate 31, a vertical guide rail group 32 and a cantilever 33. The vertical sliding plate 31 is installed on the transverse sliding block 222 by bolts, the vertical guide rail group 32 is installed on the vertical sliding plate 31, and the cantilever 33 is installed on the vertical guide rail group 32 and moves along the vertical direction under the action of the vertical guide rail group 32. The welding torch 4 is rotatably and detachably installed on the cantilever 33, so that different users can adjust the angle of holding the welding torch 4 according to their own habits and can disassemble the welding torch 4 to weld other positions.

[0034] The end of the vertical sliding plate 31 away from the transverse sliding block 222 extends in the vertical direction towards the base plate 1. The vertical guide rail group 32 comprises a vertical linear guide rail 321 and a vertical sliding block 322. The extending direction of the vertical linear guide rail 321 is consistent with the extending direction of the vertical sliding plate 31, and the vertical linear guide rail 321 is fixed on the vertical sliding plate 31 by bolts. The vertical sliding block 322 is slidingly installed on the vertical linear guide rail 321. In order to prevent the vertical sliding block 322 from falling off the vertical linear guide rail 321 under the action of gravity, the bottom of the vertical linear guide rail 321 is provided with a vertical limiting plate for blocking the vertical sliding block 322, and the vertical limiting plate is welded on the vertical sliding plate 31.

[0035] Referring to Figure 1 With Figure 2 , the cantilever 33 is bolted to the vertical slider 322 on one side, and extends away from the vertical slider 322 on the other side and protrudes from the base plate 1, and the welding tongs 4 are located on the side of the cantilever 33 away from the vertical slider 322, thereby facilitating the operation of the welding tongs 4 by the staff without being interfered by the base plate 1. The cantilever 33 moves synchronously with the vertical slider 322, thereby enabling the welding tongs 4 to slide along the extension direction of the vertical linear guide rail 321 under the action of the vertical slider 322.

[0036] Referring to Figure 1 With Figure 3 , the end of the cantilever 33 protruding from the base plate 1 is provided with a connecting plate 34, which is located at the top of the cantilever 33 and is integrally formed with the cantilever 33. A rotating hole is formed on the side of the connecting plate 34 away from the vertical slider 322, the rotating hole penetrates through the connecting plate 34, a rotating rod 35 is inserted into the rotating hole, and the rotating rod 35 can rotate in the rotating hole. The end of the rotating rod 35 away from the vertical slider 322 protrudes from the connecting plate 34 in a cantilevered state, and a collar 36 is welded to the end of the rotating rod 35 away from the vertical slider 322, the collar 36 rotates synchronously with the rotating rod 35, and the welding tongs 4 are inserted into the collar 36 and limited in the collar 36.

[0037] Referring to Figure 2 With Figure 3 , a limiting ring piece 351 is welded to the middle of the rotating rod 35, the outer diameter of the limiting ring piece 351 is greater than the hole diameter of the rotating hole, the limiting ring piece 351 is located on the side of the connecting plate 34 close to the collar 36, and the limiting ring piece 351 abuts against the connecting plate 34. The end of the rotating rod 35 away from the collar 36 also protrudes from the connecting plate 34, and a limiting nut is threadedly installed on the side of the rotating rod 35 away from the collar 36, the limiting nut is located on the side of the connecting plate 34 away from the limiting ring piece 351, thereby the limiting nut cooperates with the limiting ring piece 351 to prevent the rotating rod 35 from axially moving on the connecting plate 34, but the rotating rod 35 can rotate on the connecting plate 34.

[0038] The collar 36 is sleeved on the middle of the welding tongs 4, that is, both ends of the welding tongs 4 protrude from the collar 36, thereby facilitating the staff to continue to hold the welding tongs 4 to weld the steel lining. A tightening bolt 361 capable of being inserted into the inside of the collar 36 is threadedly installed on the outer wall of the collar 36, the tightening bolt 361 is inserted into the inside of the collar 36 and can be tightened against the outer wall of the welding tongs 4 by screwing, thereby limiting the welding tongs 4 in the collar 36. When it is needed to remove the welding tongs 4 for welding at other positions, the tightening bolt 361 can be loosened.

[0039] The implementation principle of the steel lining welding device in the embodiment of the application is as follows: when welding the steel lining, first, the worker can push the welding device to the position to be welded through the universal wheel 11, then install the electrode on the welding tongs 4, adjust the position of the welding device so that the electrode can be aligned with the position to be welded, and then lock the universal wheel 11.

[0040] Secondly, the worker can move the welding tongs 4 so that the welding tongs 4 are moved to the top of the position to be welded on the steel lining under the action of the vertical guide rail set 32, and adjust the part of the convex collar 36 of the welding tongs 4 held by hand to the angle suitable for the worker, and then start welding. During the welding process, since the welding tongs 4 are limited by the vertical guide rail set 32, the weld formed is not easy to deviate, and the welding quality is not affected. In addition, since the electrode is consumed during the welding process, the welding tongs 4 can be pushed to move downward and move closer to the steel lining, and the welding tongs 4 are limited by the horizontal guide rail set 22 when moving closer to the steel lining, so that the welding tongs 4 are not easy to deviate, and the welding quality is further improved.

[0041] The above are preferred embodiments of the application, and do not limit the protection scope of the application, so that: any equivalent changes made according to the structure, shape, principle of the application should be covered within the protection scope of the application.
