Description

Technical Field

[0001] This utility model relates to the field of pipeline welding equipment technology, specifically to a single-person operated PP-R pipe hot melt welding support. Background Technology

[0002] PP-R pipes are widely used in water facilities such as water rooms and bathrooms in buildings like hotels and dormitories. Compared to metal pipes, they are more corrosion-resistant and easier to cut and weld. In older buildings, metal pipes are being replaced with PP-R pipes. Manual welding requires at least two people, which is time-consuming and labor-intensive. Summary of the Invention

[0003] This invention addresses the technical problem of time-consuming and labor-intensive manual welding of PP-R pipes by providing a single-person PP-R pipe hot-melt welding support, enabling a single person to independently complete pipe welding work in workplaces with few operators.

[0004] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is as follows: a single-person operation PP-R pipe hot melt welding bracket, including a rectangular frame, the rectangular frame being made of four side frames that are sequentially hinged together end to end, a clamp being installed at the top of each end of one diagonal of the rectangular frame, a nut and a bushing being welded inside each end of the other diagonal of the rectangular frame, a screw being installed between the nut and the bushing, and a handle being welded to the end of the screw located on the nut side after it extends out of the outer side of the rectangular frame.

[0005] A single-person operated PP-R pipe hot-melt welding bracket includes a rectangular frame, which is composed of four side frames that are sequentially hinged together end to end. A clamp is installed at the top of each end of one diagonal of the rectangular frame, and a nut is welded inside each end of the other diagonal of the rectangular frame. A bidirectional threaded screw is installed between the two nuts. Both ends of the bidirectional threaded screw extend out of the outer side of the rectangular frame, and a handle is welded to one end of the bidirectional threaded screw.

[0006] Furthermore, the frame of the rectangular frame is made of 40*40mm hollow square steel with a length of 250mm.

[0007] Furthermore, the clamp includes a retaining ring and a base. The retaining ring is semi-circular, and the base has a semi-circular groove. The groove and the retaining ring form a circular cavity for accommodating the PP-R pipe. The two ends of the retaining ring are connected to the base by bolts.

[0008] Furthermore, the diameter of the screw is 12mm.

[0009] Compared with the prior art, the present invention has the following beneficial effects: This new welding bracket can reduce the number of operators, allowing one person to complete the welding work. Its lightweight and convenient structure improves work efficiency. Attached Figure Description

[0012] The markings in the image are as follows: 1-Rectangular frame, 2-Clamping clamp, 3-Screw, 4-Handle. Detailed Implementation

[0013] The present invention will be further described below with reference to specific embodiments. Example

[0014] like Figure 1 and 2 As shown, a single-person operated PP-R pipe hot-melt welding bracket includes a rectangular frame 1, which is composed of four side frames that are hinged together end to end. A clamp 2 is installed at the top of each end of one diagonal of the rectangular frame 1. A nut and a bushing are welded to the inside of each end of the other diagonal of the rectangular frame 1. A screw 3 is installed between the nut and the bushing. A handle 4 is welded to the end of the screw 3 located on the nut side after it extends out of the outer side of the rectangular frame 1.

[0015] Furthermore, the frame of the rectangular frame 1 is made of 40*40mm hollow square steel with a length of 250mm.

[0016] Furthermore, the clamp 2 includes a retaining ring and a base. The retaining ring is semi-circular, and the base has a semi-circular groove. The groove and the retaining ring form a circular cavity for accommodating the PP-R pipe. The two ends of the retaining ring are connected to the base by bolts.

[0017] Furthermore, the diameter of the screw 3 is 12mm.

[0018] The manufacturing process is as follows: 40*40mm hollow square steel is used, and the length of 4 hollow square steel is 250mm. A rectangular frame 1 is made. At the diagonal folding and overlapping points, the steel is hollowed out in a staggered manner, and the middle part is retained as a support for the square steel. The 4 square steels are connected by a through shaft, which can ensure that the connection point can move axially. Nuts and bushings are welded to the rectangular frame 1 from the diagonal. A 12mm diameter full-thread screw 3 is installed in the nut and bushing. The rotation of the screw 3 causes one end of the rectangular frame 1 with the welded nut to move left and right along the screw 3, which drives the pipe fittings on the clamp 2 to perform welding work.

[0019] Working principle and process: When using the welding bracket, place the two PP-R pipes to be welded into the clamp 2 respectively. One person operates the machine, holding the hot welding machine in the left hand and turning the hand crank in the right hand. The rotation of the screw causes one end of the rectangular frame 1 with the nut welded to it to move left and right along the screw 3, thereby driving the welding pipe to move left and right to move the welding end closer or further away, thus completing the welding operation.

[0020] In addition, the single-person operation PP-R pipe hot melt welding bracket of this utility model can also be: including a rectangular frame 1, the rectangular frame 1 is composed of four side frames that are hinged together end to end, a clamp 2 is installed at the top of each end of one diagonal of the rectangular frame 1, a nut is welded inside each end of the other diagonal of the rectangular frame 1, a bidirectional threaded screw is installed between the two nuts, both ends of the bidirectional threaded screw extend out of the outer side of the rectangular frame 1, and a handle 4 is welded to one end of the bidirectional threaded screw, and a limit stop is provided at the other end.

[0021] When this type of welding bracket is in operation, because the screw has a bidirectional thread, the right hand crank is turned to rotate it. The rotation of the screw causes the two ends of the rectangular frame 1 with the welded nuts to move towards or away from each other along the screw, thereby driving the welded pipes at both ends to move closer or further away, thus completing the welding operation.
