Description

Technical Field

[0001] The utility model relates to the technical field of pipeline splicing, in particular to a connecting pipe welding device. Background Art

[0002] The formwork for pouring the floor needs to be supported and fixed, and the inner tube and the outer tube are butt-jointed to form a vertically extended support structure. Now, because the floor is super high, the existing inner tube and the outer tube are not long enough to be lengthened, that is, two inner tubes are spliced ​​to form an extended inner tube, and two outer tubes are spliced ​​to form an extended outer tube;

[0003] After one end of a pipe is shrunk by a shrinking machine, it is butted against another inner pipe and then welded to form an extended pipe. The diameter of the outer pipe is larger than that of the inner pipe. The existing splicing method requires operators to manually align the pipes to be spliced. The pipes after preliminary splicing need to be welded using a fixing device. Pipes of different diameters need to be replaced with different types of fixing devices during the welding process. Alternating splicing of pipes of different diameters is prone to low efficiency.

[0004] In order to solve the above problems, a connecting pipe welding device is proposed in the present application. Utility Model Content

[0005] In view of the above-mentioned deficiencies in the prior art, the purpose of the present invention is to provide a connecting pipe welding device to overcome the above-mentioned technical problems existing in the prior art.

[0006] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0007] A connecting pipe welding device comprises a base, the outer surface of the base is fixedly connected to a first load-bearing long plate, the outer surface of the first load-bearing long plate is installed with a servo motor, the output end of the servo motor is welded with a disc, the disc is rotatably connected to a side of the first load-bearing long plate away from the servo motor, the outer surface of the disc is fixedly connected to a support plate, the side of the disc away from the servo motor is installed with an electric telescopic rod, the telescopic end of the electric telescopic rod is fixedly connected to a push plate, the top of the support plate is fixedly connected to a bracket, the top of the bracket is welded with a positioning arc plate, A first hydraulic telescopic rod is installed on the outer surface of the positioning arc plate, and the telescopic end of the first hydraulic telescopic rod is fixedly connected to a load-bearing block, and a second hydraulic telescopic rod is installed at the bottom of the load-bearing block, and the telescopic end of the second hydraulic telescopic rod is fixedly connected to an upper limit block, and the top of the support plate is slidably connected to a lower limit block, and a limit rod is welded to the top of the lower limit block, and the limit rod is movably inserted in the inner cavity of the upper limit block, and the top of the base is fixedly connected to a second load-bearing long plate, and an electric welding gun is installed on the inner surface of the second load-bearing long plate, and a wire is installed at the input end of the electric welding gun.

[0008] An arc-shaped baffle is hinged on the top of the second load-bearing long plate, and a round handle is installed on the top of the arc-shaped baffle. By setting the arc-shaped baffle and the round handle, the arc-shaped baffle can be flipped along the top of the first load-bearing long plate and the operator can control the movement of the arc-shaped baffle through the round handle. When the arc-shaped baffle is closed, the light generated during pipeline welding can be blocked as much as possible, thereby minimizing the damage of light radiation to the eyes and skin.

[0009] An exhaust port is provided on the top of the base, a load-bearing plate is welded to the inner surface of the base, a micro motor is installed at the bottom of the load-bearing plate, an exhaust fan is welded to the output end of the micro motor, and the exhaust fan is located in the exhaust port. By arranging the exhaust port, the load-bearing plate, the micro motor and the exhaust fan, starting the micro motor can drive the exhaust fan to rotate and guide the air above the base to pass through the exhaust port, which is beneficial to speed up the air flow speed during pipeline welding and try to avoid the toxic gas generated by electric welding that harms health.

[0010] A purification round box is abutted at the bottom of the base, a purifier is placed on the bottom wall of the inner surface of the purification round box, and a plurality of heat dissipation square holes are opened on the outer surface of the purification round box. By arranging the purification round box, the purifier and the heat dissipation square holes, the gas generated by the electric welding first enters the purification round box under the guidance of the exhaust fan and then passes through the heat dissipation square holes to be discharged to the outside. At the same time, the purifier in the purification round box can absorb harmful gases as much as possible to reduce the concentration of harmful gases in the air.

[0011] A pad is fixedly connected to the bottom of the base, and a bolt is threadedly connected to the inner cavity of the pad. The bolt passes through the pad and is threadedly connected to the purification round box. By arranging the pad and the bolt, the base and the purification round box are kept relatively fixed under the joint action of the pad and the bolt. When the bolt is completely separated from the inside of the purification round box by force, the operator can quickly remove the purification round box and replace the purification agent inside.

[0012] The straight-line distance from the top of the support plate to the top of the load-bearing block is smaller than the straight-line distance from the bottom of the support plate to the top of the base. By setting the height of the support plate, the straight-line distance from the bottom of the support plate to the top of the base is larger, which can avoid the bracket and other parts from colliding with the base during the flipping of the support plate, and avoid accidental damage to the parts above the support plate when flipping.

[0013] The beneficial effects of the utility model are as follows: compared with the prior art, the connecting pipe welding device provided by the utility model can drive the upper limit block to press the pipe tightly against the lower limit block through the telescopic movement of the second hydraulic telescopic rod, and the telescopic movement of the first hydraulic telescopic rod can adjust the horizontal positions of the lower limit block and the upper limit block through the load-bearing block, which is convenient for pipes of different diameters to align with each other, and at the same time, the telescopic movement of the electric telescopic rods on both sides can drive the pipe after shrinking to be connected with the normal pipe through the push plate, and after the servo motor is started, it can drive the connected pipe to flip at a uniform speed through the disc and the support plate, and the electric welding guns on both sides can perform electric welding on the connection parts of the pipes, which is convenient for pipes of different diameters to be quickly aligned with each other, and the stability of the pipes when connected to each other is improved.

After the upper limit block 13 is forced to drop and close with the lower limit block 14, the pipe to be welded remains stable under the action of the upper limit block 13 and the lower limit block 14; and because the surfaces of the upper limit block 13 and the lower limit block 14 are provided with circular holes of different diameters, the upper limit block 13 and the lower limit block 14 can fix pipes of different diameters.

Then, the operator starts the second hydraulic telescopic rod 12 to drive the upper limit block 13 to move downward. After the upper limit block 13 is forced to move downward and close with the lower limit block 14, the two pipes to be connected to each other remain fixed. The surfaces of the upper limit block 13 and the lower limit block 14 are provided with For circular holes with the same diameter, the upper limit block 13 and the lower limit block 14 can fix pipes of different diameters.
