[0003] Depending on the material, pipe connection methods are mainly divided into three types: welding connection, socket connection and clamp connection. Among them, welding connection refers to fusing the contact parts of two pipe fittings to form a whole. This connection method has the advantages of strong connection, good sealing and high pressure resistance, so it is widely used in high-voltage power pipelines.

[0004] A prior art pipe connection auxiliary device includes symmetrically arranged fixing clamps, a fixing frame driven by a cylinder, and a receiving seat located at the axis of symmetry of the symmetrically arranged fixing frame.

The pipe is fixed by the three-point limiting of the symmetrically arranged fixing clamps and the receiving seat. Then, the two fixed pipe sections are moved closer together for welding. This solution has good stability.

[0023] The following is combined Figures 1 to 5 The embodiments shown illustrate the technical solution of this utility model: This utility model provides a novel formwork support device for building engineering, such as... Figures 1-5As shown, the assembly includes a mounting plate 1, a first driving component 102, a receiving component 103, a docking plate 2, a second driving component 202, a pushing cylinder 3, a fixed bracket 4, a guide rail plate 5, an adjusting motor 403, a support component 6, and a driving disk 7. The mounting plate 1 has two first sliding grooves 101 spaced apart along its length on one side. The first driving component 102 passes sequentially into the two first sliding grooves 101 along one end of the mounting plate 1. Two receiving components 103 are symmetrically arranged on the first driving component 102, and the first driving component 102 provides the receiving components 103 with a guide rail along the first sliding grooves 101. The sliding driving force of groove 101; two docking plates 2 are symmetrically arranged on the mounting plate 1, respectively located on the opposite sides of the two receiving parts 103, and a second sliding groove 201 is provided along the length direction on the opposite side of the two docking plates 2; a second driving member 202 is arranged in the second sliding groove 201 along the length direction of the second sliding groove 201; a pushing cylinder 3 is arranged on the second driving member 202, and the second driving member 202 provides the pushing cylinder 3 with a sliding driving force along the second sliding groove 201; the fixed bracket 4 includes a connecting plate 401 and several connecting rods 402. One side of the connecting plate 401 is connected to the pushing end of the push cylinder 3, and several connecting rods 402 are evenly spaced along the circumference of the connecting plate 401; two adjusting grooves 501 are perpendicularly intersecting on one side of the guide plate 5, both ends of the adjusting grooves 501 are open, the guide plate 5 is located at the end of the connecting rod 402 away from the connecting plate 401, and the adjusting grooves 501 are opposite to the connecting plate 401; the adjusting motor 403 is located on the side of the connecting plate 401 opposite to the guide plate 5, and the driving end points towards the guide plate 5; there are four support members 6, each including a sliding... The moving rod 601, the support 602, and the adjusting block 603 are respectively symmetrically arranged at both ends of the two adjusting grooves 501 and have the degree of freedom to slide along the adjusting grooves 501. The support 602 is arranged at the end of the sliding rod 601 that is far away from each other, and the adjusting block 603 is arranged on the side of the sliding rod 601 that is away from the adjusting groove 501. The driving disk 7 is evenly spaced with four driving grooves 701 along the circumference. The adjusting block 603 is slidably connected in the corresponding driving groove 701. The driving disk 7 is coaxially connected to the driving end of the adjusting motor 403.

[0024] Specifically, the first chute 101 provides a sliding path for the first driving member 102, enabling the first driving member 102 to drive the receiving member 103 to adjust the spacing, adapting to pipes of different lengths or initial positions; the symmetrical receiving member 103 can stably support the pipe, avoiding initial placement offset; the second chute 201 of the docking plate 2 provides a track for the second driving member 202, enabling it to drive the pushing cylinder 3 to adjust its height, adapting to the stable placement of pipes with different diameters; the pushing cylinder 3 can drive the fixed bracket 4 and subsequent components to approach or move away from the pipe; the connecting plate 401 of the fixed bracket 4 ensures a stable connection with the pushing cylinder 3, and the circumferentially uniform connecting rod 402 can uniformly transmit force to the guide rail plate 5, stably connect with the guide rail plate 5, and improve the structural strength; the vertical cross adjustment groove 501 of the guide rail plate 5 provides sliding space for the support member 6, and the vertical design allows the support member 6 to cover the circumference of the pipe and adapt to pipes of different diameters; the adjustment motor 403 drives the drive disk 7 to rotate, and the drive disk 7 drives the sliding rod 601 to slide along the adjustment groove 501 through the sliding cooperation between the drive groove 701 and the adjustment block 603, so that the four support members 6 can move closer to or away from the center at the same time, and adapt to pipes of different diameters without replacing parts, solving the problem of low efficiency caused by small-range diameter adaptation and frequent part replacement in the prior art.

[0025] The first driving component 102 includes a servo motor, a bidirectional threaded screw, and a slider. The bidirectional threaded screw is rotatably connected to the mounting plate 1, and the threads in the two first slide grooves 101 are opposite. The slider is sleeved on the bidirectional threaded screw and threadedly connected to it. The two sliders slide in the two first slide grooves 101 respectively. The servo motor is installed at one end of the mounting plate 1 and coaxially connected to the bidirectional threaded screw. The receiving component 103 is installed on the slider.

[0026] A servo motor drives a bidirectional screw to rotate, thereby causing two sliders to move closer or further apart, thus adapting to pipe connections of different lengths and improving the device's adaptability.

[0027] Additionally, it should be noted that the second driving component 202 includes a servo motor, a ball screw, and a base plate. The ball screw is rotatably connected in the second slide groove 201. The servo motor is installed on the end of the docking plate 2 away from the mounting plate 1 and is coaxially connected to the ball screw. The base plate is threadedly connected to the ball screw and has the sliding freedom along the second slide groove 201. The push cylinder 3 is set on the base plate.

[0028] The servo motor drives the ball screw to rotate, thereby causing the base plate to slide along the length of the second slide groove 201, which in turn drives the push cylinder 3 to adjust the height position.

[0029] In an exemplary embodiment, see Figure 2 The support bracket 602 is crescent-shaped.

[0030] Specifically, the crescent-shaped structure can significantly improve the fit between the support bracket 602 and the outer circumference of the pipe, increase the contact area, reduce the force per unit area of ​​the pipe, avoid excessive pressure from damaging the pipe surface, and at the same time prevent the pipe from rotating circumferentially or shifting axially during the support process, ensure that the pipe maintains its predetermined position during welding, improve the docking accuracy, further adapt to the outer circumference of pipes of different diameters, and enhance the adaptability and reliability of the support component 6.

[0031] In an exemplary embodiment, the support 602 is made of rubber.

[0032] Specifically, the elasticity and flexibility of the rubber material allow the support bracket 602 to conform to the pipe surface through its own deformation, and it can also achieve stable contact through elastic compensation, thereby improving support stability and preventing the pipe from sliding during support. In addition, the soft texture of rubber will not cause scratches or rigid damage to the pipe surface, thus protecting the appearance and structural integrity of the pipe.

[0033] In an exemplary embodiment, see Figure 3 The receiving component 103 includes a receiving cylinder 1031 and a receiving pad 1032; wherein, the receiving cylinder 1031 is located on the moving end of the first driving component 102, and the pushing end points to the side away from the first sliding groove 101; the receiving pad 1032 is located on the pushing end of the receiving cylinder 1031.

[0034] Specifically, the receiving cylinder 1031 can adapt to the receiving requirements of pipes of different diameters by adjusting the height of the receiving pad 1032, without the need to replace the receiving components, thus improving adaptability; the receiving pad 1032 can effectively support the receiving pipe, limit the pipe, and prevent the pipe from tipping over or shifting; in conjunction with the sliding of the first driving component 102 along the first sliding groove 101, the receiving position and height can be adjusted simultaneously.

[0035] In an exemplary embodiment, see Figure 3 A plurality of receiving rollers 1033 are provided on the receiving pad 1032.

[0036] Specifically, the receiving roller 1033 converts the sliding friction between the receiving pad 1032 and the pipeline into rolling friction, significantly reducing the resistance to axial position adjustment of the pipeline, reducing manual intervention by operators, and avoiding wear on the pipeline surface caused by sliding friction, thus protecting the pipeline quality. Several receiving rollers 1033 can evenly distribute the pressure of the pipeline on the receiving pad 1032, avoiding excessive local pressure that could cause deformation and damage to the receiving pad 1032, thus extending its service life. Moreover, the rolling characteristic makes it easier to maintain coaxiality during pipeline adjustment, reducing eccentricity caused by sliding adjustment, ensuring the alignment accuracy of the pipeline connection ports, and especially improving the reliability and construction efficiency of welding connections.

[0037] In an exemplary embodiment, see Figure 5The mating plate 2 has a scale line 203 on one side of the opposite side, and the moving end of the second driving member 202 has an indicator needle 8.

[0038] Specifically, the scale line 203 provides a precise numerical reference for the sliding position of the second drive component 202, and the indicator needle 8 can intuitively provide position information. Operators can accurately determine the height position of the push cylinder 3 and the support component 6 by observing the scale, avoiding deviations caused by experience-based adjustments, and ensuring that the positions of the support components 6 on the two docking plates 2 are symmetrical or conform to the preset dimensions. When adapting to pipes with different diameters, it can improve position accuracy. At the same time, it facilitates positional consistency when multiple people are working together, reduces adjustment time, and improves efficiency. When fine-tuning the support position later, it can also be quickly positioned through the scale, reducing difficulty, ensuring positional stability and accuracy during pipe connection, and improving connection quality.

[0039] In an exemplary embodiment, see Figure 1 The mounting plate 1 has two third slides 104 parallel to the first slide 101 at one end away from the first slide 101 along the width direction of the mounting plate 1. The third slide 104 is provided with a third driving member 105, wherein the docking plate 2 near the third slide 104 is connected to the moving end of the third driving member 105.

[0040] Specifically, the third slide 104 provides a sliding path for the third drive component 105. The third drive component 105 can drive one of the docking plates 2 to move closer to or further away from the other docking plate 2, adapting to the docking spacing requirements of pipes of different lengths and expanding the adaptability range. The symmetrically arranged third slide 104 and third drive component 105 ensure that the docking plate 2 remains stable when sliding, reducing the error caused by the shaking of the docking plate 2 when sliding.

[0041] The third driving component 105 includes a servo motor, a ball screw, and a slider. The ball screw is rotatably connected in the third slide groove 104. The servo motor is coaxially connected to the ball screw. The slider is threadedly connected to the ball screw and has the degree of freedom to slide along the third slide groove 104. The mating plate 2 near the third slide groove 104 is connected to the slider in the third slide groove 104.

[0042] The servo motor drives the slider to move along the third slide groove 104, thereby moving one docking plate 2 closer to or further away from another docking plate 2, improving the adaptability to different pipes.

[0043] In an exemplary embodiment, see Figure 4 The docking plate 2 is symmetrically provided with guide grooves 204 on both sides of the second slide groove 201, and the moving end of the second driving member 202 is slidably connected in the guide grooves 204.

[0044] The base pad in the second drive unit 202 has slide bars on both sides, which are slidably connected in the guide groove 204. The guide groove 204 and the slide bars have trapezoidal cross sections. When the servo motor in the second drive unit 202 drives the base pad to move along the second slide groove 201, the slide bars and guide groove 204 on both sides can further provide support and connection stability for the base pad.

[0045] Specifically, the guide groove 204 and the second slide groove 201 cooperate to provide dual guidance for the second driving component 202, avoiding swaying, offset, and jamming caused by unilateral force or gap during sliding, ensuring smooth and straight sliding, and thus ensuring the accurate positioning of the push cylinder 3 and the support component 6; the symmetrical guide groove 204 makes the moving end uniformly stressed, reduces frictional resistance, reduces wear of the driving component, extends service life, and improves connection quality and construction efficiency.

[0046] In an exemplary embodiment, see Figure 1 The mounting plate 1 has multiple casters 106 on the side opposite to the first slide groove 101.

[0047] Specifically, the casters 106 enable the device to move flexibly, allowing operators to easily push it to the target work area without the need for large handling equipment, reducing the difficulty and physical exertion of handling. It is especially suitable for the construction of power pipelines with long paths and multiple connection points, improving flexibility.

[0048] The technical features of the above embodiments can be combined in any way (as long as there is no contradiction in the combination of these technical features). For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described; these embodiments not explicitly written should also be considered to be within the scope of this specification.

It should be understood that, based on the technical concept of the present application, several conventional adjustments or further innovations can be made to these specific embodiments; however, as long as they do not depart from the technical concept of the present application, the technical solutions obtained by these conventional adjustments or further innovations also fall within the protection scope of the claims of the present application.
