Description

Technical Field

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

[0002] In the process of repairing large-diameter pipelines, such as the repair process of pipelines with a diameter of 800cm-1000cm in chemical plants or water supply lines, the stainless steel lining repair method is generally used to repair large-diameter pipelines. 2mm-5mm thick stainless steel plates are made into curved stainless steel plates in the form of rolled plates, which are welded tightly against the inner wall of the original pipeline inside the original pipeline, and stainless steel pipe sections are formed inside the pipeline, thereby achieving the purpose of anti-leakage and anti-corrosion. In the process of laying the curved stainless steel plate in the pipeline, some construction methods are to manually support the curved stainless steel plate, and then weld the curved stainless steel plate to fix it in the pipeline and form a stainless steel pipe section in the pipeline with multiple curved stainless steel plates. Manually supporting the curved stainless steel plate requires a lot of physical strength. Since it is inconvenient to move in the pipeline, the labor intensity of manually supporting the curved stainless steel plate is relatively high.

[0003] The patent document with application number CN202210531414.1 discloses a trenchless repair method for ground pipelines. In its steps s8-s11, air is inflated into a braided hose to make it expand, thereby supporting the arc-shaped lining repair plate. However, the support method of the lining repair plate using a braided hose is only suitable for the construction operation of connecting the lining repair plate to the pipeline by bonding, and is not suitable for the construction operation of connecting the lining repair plate to the pipeline by welding.

[0004] The patent document with application number CN202222813290.4 discloses a pipe supporter, which moves an arc-shaped stainless steel plate into a pipe. When supporting the arc-shaped stainless steel plate, the position of the lower arc-shaped stainless steel plate is first determined, and then the pipe supporter is placed in the lower arc-shaped stainless steel plate, and then the upper arc-shaped stainless steel plate is located above the pipe supporter, and the motor is started. The motor drives the forward and reverse screws to rotate. During the rotation of the forward and reverse screws, the two screw sleeves in the pipe body are relatively close to each other, and the screw sleeves cause the swing arm to swing through the support rod. During the swing of the swing arm, the arc-shaped stainless steel plate is supported by the support wheel and is pressed against the inner wall of the pipe. When the position of the upper arc-shaped stainless steel plate needs to be adjusted, the upper handle is turned to make the screw withdraw from the hole of the upper swing arm, and then the driving rod is rotated as a whole to make the arc surface and the pipe be in contact with each other. The axle of the support wheel is separated. After the arc surface is separated from the axle of the support wheel, the support wheel will approach the tube body along the length direction of the slide. At this time, the upper support wheel loses its support function for the upper arc-shaped stainless steel plate. Then, the upper arc-shaped stainless steel plate can be adjusted. After the position adjustment of the upper arc-shaped stainless steel plate is completed, the drive rod is rotated to restore it. During the rotation of the drive rod, the guide surface can guide the axle of the support wheel, and then during the rotation and restoration of the drive rod, the support wheel is moved away from the tube body along the length direction of the slide. When the buckle sleeve is set on the drive rod, the drive rod is limited. At this time, the screw rod corresponds to the hole on the swing rod, the arc surface contacts the axle of the support wheel, and the support wheel is restored to the starting position. The handle is turned to insert the screw rod into the hole on the swing rod, and then the drive rod is positioned, and the support wheel continues to support the arc-shaped stainless steel plate. Then the arc-shaped stainless steel plate can be welded. When the pipe supporter supports the stainless steel plate, it is inconvenient to change the contact point between the supporting wheel and the stainless steel plate. When the stainless steel plate is deformed, the gap between the stainless steel plate and the inner wall of the pipe is large, and the gap between the stainless steel plate and the pipe needs to be manually adjusted during welding.

[0005] The patent document with application number CN201120423505.0 discloses a pipe support. During construction, the pipe support is placed in the pipe blank, and the forward and reverse screws are rotated, and the forward and reverse screw nuts move toward the middle sleeve, so that the support wheels are opened, and the support wheels press the pipe blank so that the pipe blank is tightly attached to the inner wall of the pipe to be repaired. Similarly, in the process of supporting the pipe blank, the contact point between the support wheel and the pipe blank is not convenient to change. When the gap between the pipe blank and the inner wall of the pipe is large, the gap between the pipe blank and the pipe needs to be manually adjusted during the welding process.

[0031] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0032] Example 1: Reference Figure 1-Figure 4 As shown, a pipe support comprises two symmetrically arranged top plates 2, and the two top plates 2 are connected by a plurality of telescopic parts. Specifically, the telescopic parts are double-end telescopic rods 1, and the two telescopic ends of the double-end telescopic rods 1 are fixedly connected to the two top plates 2. Simultaneously starting a plurality of double-end telescopic rods 1 can adjust the distance between the two top plates 2.

[0033] A rotating rod 5 is rotatably provided on the top plate 2, and both ends of the rotating rod 5 are located outside the top plate 2 on one side thereof. Multi-stage telescopic rods 3 are fixed to both ends of the rotating rod 5, and the telescopic ends of the two multi-stage telescopic rods 3 on the same side are rotatably connected by a pressure rod 4.

[0034] A gear 6 is coaxially fixed on the rotating rod 5, and a driving assembly connected to the gear 6 is provided on the top plate 2. The driving assembly includes a fixed plate 7 fixed on the top plate 2, a rack 8 is slidably connected to the fixed plate 7, and the rack 8 is meshed with the gear 6. An electric push rod 9 is fixed on the top plate 2, and the telescopic end of the electric push rod 9 is fixedly connected to the rack 8.

[0035] When installing the lining repair plate 11, the device is located between the two lining repair plates 11 in the pipeline 10. Then, a plurality of double-end telescopic rods 1 are simultaneously started, so that the two top plates 2 support the two lining repair plates 11 respectively.

[0036] When the distance between the lining repair plate 11 and the inner wall of the pipe 10 needs to be adjusted, the electric push rod 9 is started so that the rack 8 drives the gear 6 and the rotating rod 5 to rotate. During the rotation of the rotating rod 5, the positions of the multi-stage telescopic rod 3 on the rotating rod 5 and the pressure rod 4 rotatably connected to the multi-stage telescopic rod 3 can be adjusted. When the pressure rod 4 corresponds to the position where the lining repair plate 11 needs to be squeezed, the electric push rod 9 is closed, and then the two multi-stage telescopic rods 3 are started at the same time. The pressure rod 4 can squeeze the lining repair plate 11 and reduce the gap between the lining repair plate 11 and the inner wall of the pipe 10. This makes it easier to weld the pipe 10 and the lining repair plate 11.

[0037] Embodiment 2: Based on Embodiment 1, refer to Figure 4 As shown, the end of the top plate 2 away from the telescopic member is arc-shaped. The end of the top plate 2 away from the telescopic member is used to press against the inner lining repair plate 11. The end of the top plate 2 away from the telescopic member is set to be arc-shaped, which can increase the contact area between the top plate 2 and the inner lining repair plate 11, and can avoid the inner lining repair plate 11 from being indented after the top plate 2 applies force to the inner lining repair plate 11.

[0038] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
