Description

Technical Field

[0001] This utility model belongs to the field of pipeline processing technology, specifically a fixed support for pipeline welding processing. Background Technology

[0002] Pipelines are devices made up of pipes, pipe fittings, and valves used to transport gases, liquids, or fluids containing solid particles. After being pressurized by blowers, compressors, pumps, and boilers, the fluid flows from the high-pressure area to the low-pressure area in the pipeline. It can also be transported using the fluid's own pressure or gravity. Pipelines are mainly used for water supply, drainage, heating, gas supply, long-distance transportation of oil and natural gas, agricultural irrigation, hydraulic engineering, and various industrial installations. After prolonged use, gaps are prone to appear on the surface of pipelines, affecting the flow of fluid in the pipeline. These gaps need to be sealed by welding.

[0003] Existing pipe welding and fixing supports typically place the supports directly on the bottom of the pipe to support it, raising the pipe to a certain height to facilitate welding. However, the vibrations generated during welding are transmitted to the supports, which can easily cause them to sway, tilt, or detach from the pipe, thus affecting their support. Therefore, improvements are needed. Utility Model Content

[0004] To overcome the above-mentioned defects, this utility model provides a fixed support for pipe welding, which solves the problem that existing fixed supports for pipe welding generally support the pipe directly at the bottom of the pipe and raise the pipe to a certain height to facilitate welding of pipe gaps. However, the vibration generated during the welding process is transmitted to the fixed support, which can easily cause the fixed support to sway, tilt, and detach from the pipe, thus affecting the support of the pipe.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a fixed bracket for pipe welding processing, comprising a base plate, a rectangular groove on one side of the base plate, a movable seat slidably connected inside the rectangular groove, an mounting plate fixedly connected to the top of the base plate away from the rectangular groove and the top of the movable seat respectively, an mounting seat on the top of the mounting plate, a fixed seat rotatably connected to the top of the mounting seat on both sides by pins, fixed rollers rotatably mounted on the inner walls of the mounting seat and the inner walls of the fixed seat by rotating shafts, a fixed hook fixedly connected to one end of one fixed seat, a lever plate rotatably mounted on one end of the other fixed seat by pins, fixed plates rotatably mounted on both sides of the lever plate by pins, and the fixed plates and fixed hooks are correspondingly engaged with each other.

[0006] As a further embodiment of this utility model: three through holes are respectively provided at the bottom of both sides of the mounting base, and positioning protrusions are fixedly connected at the four corners of the top of the mounting plate, and the positioning protrusions correspond to the positions of the through holes.

[0007] As a further embodiment of this utility model: a fixing stud is fixedly connected to the top of the mounting plate between two positioning protrusions, and the fixing stud corresponds to the position of the through hole. The top of the fixing stud passes through the through hole and is threadedly connected to a fixing nut.

[0008] As a further embodiment of this utility model: the inner wall of the rectangular groove is provided with limiting grooves on both sides, and the movable seat is symmetrically mounted with limiting rollers on both sides via a rotating axis, and the limiting rollers are tactilely connected to the inside of the limiting groove.

[0009] As a further embodiment of this utility model: a movable stud is rotatably installed at the center of the rectangular groove via a bearing, the movable stud is threadedly connected to the movable seat, and limit slide rods are symmetrically fixedly connected on both sides of the movable stud inside the rectangular groove, and the limit slide rods are slidably connected to both sides of the movable seat.

[0010] As a further embodiment of this utility model: one end of the movable stud extends through the rectangular groove to the outside of the base plate and is fixedly connected to a locking stud, and a locking sleeve is threaded through the surface of the locking stud, and the locking sleeve is in close contact with the outside of the base plate.

[0011] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0012] 1. This pipe welding processing fixed support consists of an installation seat, a fixed seat, and fixed rollers. A lever is moved to disengage the fixed clamping plate from the fixed hook. The fixed seat is rotated to open at the top of the installation seat, allowing the pipe to rest on top of the two installation seats. The pipe welding position is ensured to be within the two installation seat supports, with the pipe surface pressed tightly against the top of the fixed rollers. The fixed seat is then flipped to lock onto the pipe surface, closing the two fixed seats tightly against the pipe surface. Rotating the lever engages the fixed clamping plate with the fixed hook, causing the fixed seat and fixed rollers to press firmly against the pipe surface. The pipe is clamped and fixed between the installation seat and the fixed seat for welding. Pushing the installation seat causes the fixed rollers to roll on the pipe surface, ensuring the base plate is placed parallel to the ground to support the pipe and prevent it from sagging or tilting during welding.

[0013] 2. The fixed support for pipe welding is configured with a movable seat, a movable stud, and a locking sleeve. After fixing the two mounting seats to the top of their respective mounting plates, rotating the locking stud causes the movable stud to rotate inside the rectangular groove. This adjusts the position of the movable seat within the rectangular groove, allowing for easy adjustment of the distance between the two mounting seats according to the length of the pipe welding position. Once the two mounting seats are secured at both ends of the pipe weld, the locking sleeve is tightened to lock and secure the locking stud, ensuring that the movable stud does not rotate freely within the rectangular groove and that the mounting seats and fixed seats are held in place at both ends of the pipe weld without slipping.

[0018] The technical solution of this patent will be further described in detail below with reference to specific embodiments.

[0019] like Figure 1-3 As shown, this utility model provides a technical solution: a fixed bracket for pipe welding processing, including a base plate 1, a rectangular groove 19 on one side of the base plate 1, a movable seat 2 slidably connected inside the rectangular groove 19, an mounting plate 3 fixedly connected to the top of the base plate 1 away from the rectangular groove 19 and the top of the movable seat 2 respectively, an mounting seat 4 on the top of the mounting plate 3, three through holes 10 through the bottom of both sides of the mounting seat 4 respectively, and positioning protrusions 11 fixedly connected to the four corners of the top of the mounting plate 3 respectively, and the positioning protrusions 11 correspond to the positions of the through holes 10. By providing positioning protrusions 11, the mounting seat 4 is placed close to the top of the mounting plate 3, so that the positioning protrusions 11 are engaged in the corresponding through holes 10, ensuring that the mounting seat 4 is fixed on the top of the mounting plate 3 without misalignment.

[0020] A fixing stud 12 is fixedly connected to the top of the mounting plate 3 between the two positioning protrusions 11, and the fixing stud 12 corresponds to the position of the through hole 10. The top of the fixing stud 12 passes through the through hole 10 and is threadedly connected to a fixing nut 20. Because of the fixing stud 12 and the fixing nut 20, after the mounting base 4 is aligned and placed tightly on the top of the mounting plate 3, and the fixing stud 12 passes through the corresponding through hole 10, the fixing nut 20 is tightened, thereby fixing the mounting base 4 to the top of the mounting plate 3.

[0021] The top of the mounting base 4 is rotatably connected to two fixed bases 5 via pins. The inner walls of the mounting base 4 and the inner walls of the fixed bases 5 are rotatably mounted with fixed rollers 6 via shafts. One fixed base 5 is fixedly connected to a fixed hook 7 at one end, and the other fixed base 5 is rotatably mounted to a lever 8 via a pin at one end. Fixed plates 9 are rotatably mounted on both sides of the lever 8 via pins, and the fixed plates 9 and fixed hooks 7 are correspondingly engaged. With the fixed hooks 7 and fixed plates 9, when the pipe is placed on the top of the mounting base 4, the two fixed bases 5 are rotated to clamp the top of the pipe. Rotating the lever 8 causes the fixed plates 9 to engage with the fixed hooks 7, thereby causing the fixed base 5 to drive the fixed rollers 6 to be tightly fixed to the surface of the pipe, thus clamping and fixing the pipe.

[0022] Limiting grooves 13 are provided on both sides of the inner wall of the rectangular groove 19. Limiting rollers 14 are symmetrically mounted on both sides of the movable seat 2 via a rotating shaft, and the limiting rollers 14 are tactilely connected to the inside of the limiting grooves 13. Because of the limiting rollers 14, the movable seat 2 slides inside the rectangular groove 19, driving the limiting rollers 14 to roll inside the limiting grooves 13, thereby reducing the friction of the movable seat 2 moving inside the rectangular groove 19.

[0023] A movable stud 15 is rotatably mounted at the center of the rectangular groove 19 via a bearing. The movable stud 15 is threadedly connected to the movable seat 2. Limiting slide rods 16 are symmetrically fixedly connected on both sides of the movable stud 15 inside the rectangular groove 19, and the limiting slide rods 16 are slidably connected to both sides of the movable seat 2. By providing the movable stud 15, the rotation of the movable stud 15 inside the rectangular groove 19 is controlled, so that the movable seat 2 moves on the surface of the movable stud 15, and the position of the movable seat 2 inside the rectangular groove 19 is adjusted, so that the distance between the two mounting seats 4 can be adjusted according to the length of the pipe weld.

[0024] One end of the movable stud 15 extends through the rectangular groove 19 to the outside of the base plate 1 and is fixedly connected to a locking stud 17. A locking sleeve 18 is threaded through the surface of the locking stud 17 and is tightly attached to the outside of the base plate 1. Because of the locking sleeve 18, after the movable seat 2 moves to a suitable position on the surface of the movable stud 15, the locking sleeve 18 is tightened to lock and fix the locking stud 17, ensuring that the movable stud 15 will not rotate arbitrarily inside the rectangular groove 19.

[0025] The working principle of this utility model is as follows:

[0026] Select the corresponding mounting base 4 according to the pipe specifications, place the mounting base 4 firmly against the top of the mounting plate 3, and insert the positioning protrusion 11 and the fixing stud 12 into the corresponding through hole 10. Secure the mounting base 4 to the top of the mounting plate 3 by tightening the fixing nut 20. Rotate the locking stud 17 to control the movement stud 15 to rotate inside the rectangular groove 19. Adjust the position of the moving base 2 inside the rectangular groove 19. Adjust the distance between the two mounting bases 4 according to the length of the pipe weld. Rotate to open the fixing base 5 on the top of the mounting base 4, and place the pipe on the two mounting bases 4. At the top, position the pipe weld between the two mounting seats 4, rotate the fixing seat 5 to cover the pipe surface, and make the fixing roller 6 close to the pipe surface. Then rotate the lever 8 to make the fixing plate 9 engage with the fixing hook 7, thereby closing and fixing the two fixing seats 5 tightly. This clamps and fixes the mounting seats 4 and fixing seats 5 at both ends of the pipe weld. Push the mounting seats 4 and fixing seats 5 to rotate on the pipe surface until the base plate 1 is placed parallel to the ground, so that the mounting seats 4 and fixing seats 5 support the pipe, making it convenient for the processing personnel to perform welding processing on the pipe weld.
