[0002] During the construction process of electric power engineering, in order to improve the construction efficiency, the modular construction method is generally used. For example, during the construction of cable tunnels, prefabricated tunnel boxes are generally used for assembly. Using prefabricated tunnel boxes for assembly can greatly shorten the construction efficiency, and welding devices are required for the production of the boxes.

[0003] A welding device for steel plates in electric power engineering is proposed in the published patent document CN117921288A. It includes a bottom plate, two support frames are arranged at the upper end of the bottom plate. The support frame includes a plurality of mutually parallel support rods. The upper end of the support rod is hinged to the electromagnetic suction plate, and the lower end of the support rod is elastically rotatably connected to the bottom plate. A support frame is arranged above the bottom plate. The support frame is connected to the bottom plate through a lifting assembly. A sliding frame is fixed inside the support frame. An upper slider is slidably connected inside the sliding frame. An upper driving assembly is arranged inside the sliding frame. A lower driving assembly is arranged inside the gantry. The lower end of the lower slider is fixed with a telescopic rod, and the lower end of the telescopic rod is fixed with a welding head.

[0004] At least the following problems in the prior art have not been solved:

[0005] After the electromagnetic suction plate descends, it is supported by the elastic force of the torsion spring. The support method is not stable, and it is easy to cause inaccurate butt joint of the welding material due to the inability of the electromagnetic suction plate to provide stable support during the welding process, resulting in inaccurate welding. For this reason, we propose a welding device for electric power engineering. Content of the Utility Model

[0006] The purpose of the utility model is to provide a welding device for electric power engineering to solve the problems raised in the above background technique.

[0007] To achieve the above purpose, the utility model provides the following technical solution: A welding device for electric power engineering includes a first support member. The upper surface of the first support member is connected to two groups of second support members through telescopic members. A set of locking components is arranged below each group of second support members, which can play a role in stabilizing the second support members. A positioning member is arranged above the two groups of second support members. The positioning member can be lifted and lowered, and a welding component is arranged above the positioning member.

[0008] Preferably, the locking assembly includes a first connecting rod, a first slider, a second connecting rod, and a first electric push rod. The bottom end of each group of the second support members is hinged to a group of the first connecting rods. The other end of the first connecting rod is hinged to the first slider. The first slider is slidably connected to the second connecting rod. The second connecting rod is installed on one side of the first support member.

The output end of the first electric push rod can penetrate the first slider and abut against the second connecting rod for locking.

[0009] Preferably, the positioning member includes a limiting frame, a limiting block, and a second electric push rod. The limiting frame is arranged above the two groups of the second support members. A group of the limiting blocks are installed in the inner cavity of the limiting frame corresponding to the two groups of the second support members respectively. A group of the second electric push rods are installed at both ends of the limiting frame. The second electric push rods are connected to the first support member.

[0010] Preferably, the welding assembly includes a third support member, a second slider, a welding torch, a screw rod, and a motor. The third support member is arranged at the position where the two groups of the second support members are attached. The second slider is slidably installed in the inner cavity of the third support member. The welding torch is installed at the bottom end of the second slider. The second slider is penetrated by the screw rod and is threadedly connected thereto. The screw rod is rotatably connected to the third support member and one end thereof is connected to the output end of the motor. The third support member can be adjusted in height through a lifting assembly.

[0011] Preferably, the lifting assembly includes a connecting seat and a third electric push rod. One end of the third support member is installed with the connecting seat. The connecting seat is connected to the output end of the third electric push rod.

[0012] Preferably, the telescopic member includes a telescopic rod and a spring. Four groups of the telescopic rods are installed at the bottom end of each group of the second support members. A group of the springs are sleeved outside each group of the telescopic rods.

[0013] Compared with the prior art, the beneficial effects of the present utility model are as follows:

[0014] 1. When the utility model needs to weld steel plates with different thicknesses, place the two steel plates with different thicknesses on two second support members respectively, and make the opposite end faces of the two steel plates with different thicknesses parallel. By lowering the positioning member, the thicker group of steel plates is pushed to drive the connected group of second support members to lower first, so that it gradually becomes flush with the thinner steel plate placed on the other group of second support members. Then, use the locking assembly to lock the height of the second support member so that it cannot move anymore. Then, use the welding assembly to weld, which helps to improve the stability during the welding of the two groups of steel plates. Compared with the prior art, the position of the second support member can be locked, and it is more stable than the way of spring force support of the torsion spring, which helps to improve the stability during welding.

[0015] 2. When the second support member of the utility model is lowered, it will drive the first connecting rod to push the first slider to slide along the second connecting rod. Then, by extending the first electric push rod, it penetrates the first slider and abuts against the second connecting rod to lock, so that the first slider cannot move, and thus the second support member cannot continue to lower. By contracting the second electric push rod, the limiting frame can be pulled to drive the limiting block to lower, so that the limiting block pushes the steel plate to lower, driving the second support member to move down, making the second support member unable to rise again. Cooperating with the locking assembly, the second support member cannot descend either, thus realizing the fixation of the position of the second support member. By contracting the third electric push rod, the connecting seat can be driven to lower, and then the third support member is driven to lower, completing the lowering of the welding assembly, which is convenient for welding. By starting the motor, the screw rod is driven to rotate, so that the second slider threadedly connected with it drives the welding torch to move, and the steel plate can be welded. The telescopic rod and the spring form a telescopic member, which can be telescoped and reset, facilitating the reset of the second support member. Description of the Drawings

A positioning member is provided above the two groups of second support members 2. The positioning member can be lifted and lowered, and a welding component is provided above the positioning member.

[0025] In this embodiment, when welding steel plates with different thicknesses, the two steel plates with different thicknesses are respectively placed on the two second support members 2, and the opposite end faces of the two steel plates with different thicknesses are made parallel. By lowering the positioning member, the thicker group of steel plates is pushed to drive the group of second support members 2 connected thereto to lower, so that it gradually becomes flush with the thinner steel plate placed on the other group of second support members 2. Then, the height of the second support member 2 is locked by using the locking component so that it cannot move anymore. Then, welding is performed by using the welding component, which helps to improve the stability during the welding of the two groups of steel plates. Compared with the prior art, the position of the second support member 2 can be locked, and compared with the way of spring force support of the torsion spring, it is more stable and helps to improve the stability during welding.

[0026] Please refer to Figures 1-5As shown, the locking component includes a first connecting rod 3, a first slider 4, a second connecting rod 5, and a first electric push rod 6. The bottom end of each group of second support members 2 is hinged to a group of first connecting rods 3. The other end of the first connecting rod 3 is hinged to the first slider 4. The first slider 4 is slidably connected to the second connecting rod 5. The second connecting rod 5 is installed on one side of the first support member 1. A first electric push rod 6 is installed on one side of the first slider 4. The output end of the first electric push rod 6 can penetrate the first slider 4 and abut against the second connecting rod 5 for locking.

[0027] In this embodiment, when the second support member 2 is lowered, it will drive the first connecting rod 3 to push the first slider 4 to slide along the second connecting rod 5. Then, by extending the first electric push rod 6, it penetrates the first slider 4 and abuts against the second connecting rod 5 for locking, so that the first slider 4 cannot move, and thus the second support member 2 cannot continue to be lowered.

[0028] Please refer to Figures 1-5 As shown, the positioning component includes a limiting frame 8, a limiting block 9, and a second electric push rod 10. A limiting frame 8 is provided above the two groups of second support members 2. A limiting block 9 is installed in the inner cavity of the limiting frame 8 corresponding to each of the two groups of second support members 2. A second electric push rod 10 is installed at each end of the limiting frame 8. The second electric push rod 10 is connected to the first support member 1. The welding component includes a third support member 11, a second slider 12, a welding torch 13, a screw rod 14, and a motor 15. A third support member 11 is provided at the position where the two groups of second support members 2 are in contact. The second slider 12 is slidably installed in the inner cavity of the third support member 11. The welding torch 13 is installed at the bottom end of the second slider 12. The second slider 12 is penetrated by the screw rod 14 and is threadedly connected thereto. The screw rod 14 is rotatably connected to the third support member 11, and one end thereof is connected to the output end of the motor 15. The third support member 11 can be adjusted in height through a lifting component. The lifting component includes a connecting seat 16 and a third electric push rod 17. One end of the third support member 11 is installed with the connecting seat 16. The connecting seat 16 is connected to the output end of the third electric push rod 17. The telescopic member includes a telescopic rod 7 and a spring 18. Four telescopic rods 7 are installed at the bottom end of each group of second support members 2. A spring 18 is sleeved outside each telescopic rod 7.

[0029] In this embodiment, by retracting the second electric push rod 10, the limiting frame 8 can be pulled to drive the limiting block 9 to lower, so that the limiting block 9 pushes the steel plate to lower, driving the second support member 2 to move downwards, making the second support member 2 unable to rise anymore. Cooperating with the locking component, the second support member 2 cannot descend either. Thus, the position of the second support member 2 is fixed. By retracting the third electric push rod 17, the connecting seat 16 can be driven to lower, and then the third support member 11 is driven to lower, completing the lowering of the welding component, facilitating welding. By starting the motor 15, the screw rod 14 is driven to rotate, so that the second slider 12 threadedly connected thereto drives the welding torch 13 to move, and the steel plate can be welded. The telescopic rod 7 and the spring 18 form a telescopic member, which can perform telescopic reset to facilitate the reset of the second support member 2.

[0030] Working principle: First, by retracting the second electric push rod 10, the limiting frame 8 can be pulled to drive the limiting block 9 to lower, so that the limiting block 9 pushes the steel plate to lower, driving the second support member 2 to move downwards, making the second support member 2 unable to rise anymore. Cooperating with the locking component, the second support member 2 cannot descend either. When the second support member 2 descends, it will drive the first connecting rod 3 to push the first slider 4 to slide along the second connecting rod 5. Then, by extending the first electric push rod 6, it penetrates the first slider 4 and abuts against the second connecting rod 5 for locking, making the first slider 4 unable to move, and thus the second support member 2 cannot continue to lower. Thus, the position of the second support member 2 is fixed. By retracting the third electric push rod 17, the connecting seat 16 can be driven to lower, and then the third support member 11 is driven to lower, completing the lowering of the welding component, facilitating welding. By starting the motor 15, the screw rod 14 is driven to rotate, so that the second slider 12 threadedly connected thereto drives the welding torch 13 to move, and the steel plate can be welded. The telescopic rod 7 and the spring 18 form a telescopic member, which can perform telescopic reset to facilitate the reset of the second support member 2.
