Description

Technical Field

[0001] This utility model relates to the technical field of pipeline connection auxiliary devices, specifically to a pipeline traction machine linkage adjustment device. Background Technology

[0002] In modern industrial production and infrastructure construction, urban water supply, drainage, and various chemical material transportation pipeline systems all require the secure connection of numerous pipe sections. Generally, multiple workers are needed to work together to move and align the ends of the two pipes to be connected.

[0003] Due to the lack of a stable support structure when aligning and pulling heavy pipes, the pipes are prone to rolling and shifting due to their own weight after placement. In addition, the lack of effective alignment and guidance components often leads to misalignment of the two pipe ports during actual installation, affecting the stability of the connection. The connection must then be disconnected and reinstalled. Utility Model Content

[0004] To address the aforementioned problems, this utility model proposes a pipeline traction machine linkage adjustment device, comprising an adjustment base, a placement arc groove for placing pipelines on the top of the adjustment base, a mounting top seat above the adjustment base, and support columns fixed between the mounting top seat and both ends of the adjustment base; two symmetrically arranged adjusting screws with opposite thread directions are arranged above the mounting top seat, and the two adjusting screws are fixed together by a connecting rod, one of the adjusting screws is connected to a servo motor at its end via a coupling, and the other adjusting screw is rotatably connected to a connecting plate fixed on the mounting top seat, adjusting blocks are threaded to the outer sides of both adjusting screws, the bottom of the adjusting blocks extends to below the mounting top seat, the mounting top seat has two through grooves for the adjusting blocks to slide laterally, a connecting plate is fixed to the bottom of the adjusting blocks, an electric push rod is installed at the bottom of the connecting plate, a traction block is fixed to the telescopic end of the electric push rod, and an arc groove is formed at the bottom of the traction block.

[0005] Furthermore, the bottom of the connecting plate is provided with a plug hole, and a slide rod is slidably connected to the plug hole. A sleeve is fixed to the bottom of the slide rod, and a tension spring is fixed between the top of the sleeve and the bottom of the connecting plate. The tension spring is sleeved on the outside of the slide rod, and a locking rod is slidably connected to the sleeve. A locking block is fixed to the end of the locking rod away from the electric push rod, and an internal hexagonal locking groove is provided at the end of the locking block. An L-shaped rotating handle is fixed to the end of the locking rod near the electric push rod.

[0006] Furthermore, two positioning discs are fixed on the outer side of the locking rod to both sides of the sleeve.

[0007] Furthermore, anti-slip rubber strips are fixed inside the arc-shaped groove of the traction block.

[0008] Furthermore, an operating cavity is provided in the middle of the adjusting base below the placement arc groove.

[0009] The beneficial effects of this utility model are as follows: 1. By driving two adjusting screws with opposite screw directions through a servo motor, two traction blocks can be controlled to move two pipes, thereby achieving traction of the pipes and accurately aligning the two pipes. This reduces the intensity and error of manual operation, and the advantages are more obvious, especially when installing long and heavy pipes.

[0010] 2. The locking rod and related components of the device can be easily connected and matched with the flange. The connection is achieved by using hexagonal bolts and the internal hexagonal locking groove of the locking block. During the connection process, the traction block continuously presses down on the pipeline, and the two work together to ensure the stability of the connection operation.

For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0015] The present invention will be further described below with reference to the accompanying drawings: A pipeline traction machine linkage adjustment device, such as Figure 1 and Figure 2 As shown, the device includes an adjusting base 1, with a placement groove 101 on the top for placing pipes. An operating cavity 102 is located in the middle of the adjusting base 1 below the placement groove 101. A mounting top 2 is positioned above the adjusting base 1, and support columns 3 are fixed between the mounting top 2 and both ends of the adjusting base 1. Two adjusting screws 4 with opposite thread directions are symmetrically arranged above the mounting top 2, and the two adjusting screws 4 are fixed together by a connecting rod 5. One adjusting screw 4 is connected to a servo motor 6 via a coupling at its end, and the other adjusting screw 4... The end of the adjusting screw 4 is rotatably connected to a connecting plate 7 fixed on the mounting top seat 2. The outer sides of the two adjusting screws 4 are threaded with adjusting blocks 8. The bottom of the adjusting blocks 8 extends to the bottom of the mounting top seat 2. The mounting top seat 2 has two sliding grooves through the top and bottom for the adjusting blocks 8 to slide laterally. The bottom of the adjusting blocks 8 is fixed with a connecting plate 9. An electric push rod 10 is installed at the bottom of the connecting plate 9. A traction block 11 is fixed at the telescopic end of the electric push rod 10. An anti-slip rubber strip 19 is fixed in the arc groove of the traction block 11. An arc groove is opened at the bottom of the traction block 11.

[0016] The adjusting screw 4 is driven by a servo motor 6, and the adjusting block 8 moves synchronously in opposite directions via a threaded transmission connection. The adjusting block 8 transmits motion to the pipeline via components such as a connecting plate 9 and an electric push rod 10. The traction block 11, in conjunction with the anti-slip rubber strip 19, uses friction to move the pipeline, completing the pipeline alignment and traction operation.

[0017] like Figure 1 and Figure 3As shown, in this embodiment, the bottom of the connecting plate 9 is provided with a plug hole, and a slide rod 12 is slidably connected to the plug hole. A sleeve 13 is fixed to the bottom of the slide rod 12. A tension spring 14 is fixed between the top of the sleeve 13 and the bottom of the connecting plate 9. The tension spring 14 is sleeved on the outside of the slide rod 12. A locking rod 15 is slidably connected to the sleeve 13. A locking block 16 is fixed to the end of the locking rod 15 away from the electric push rod 10. An internal hexagonal locking groove is provided at the end of the locking block 16. An L-shaped rotating handle 17 is fixed to the end of the locking rod 15 near the electric push rod 10. Two positioning discs 18 are fixed to the outer side of the locking rod 15 on both sides of the sleeve 13.

[0018] The locking rod 15 is slidably connected to the sleeve 13, allowing for flexible position adjustment. The tension spring 14 provides elastic restoring force, the positioning plate 18 serves as a guide and limiter, and the rotating handle 17 facilitates manual operation of the locking rod 15 by the operator. The internal hexagonal locking groove of the locking block 16 cooperates with the hexagonal bolt to achieve rapid locking of the flange connection hole.

[0019] The working principle of this utility model is as follows: When the pipeline needs to be pulled and aligned, the electric push rod 10 is activated first. Its telescopic end drives the traction block 11 downward, so that the anti-slip rubber strip 19 at the bottom of the traction block 11 makes close contact with and presses against the top of the pipeline. At this time, there is a large static friction between the anti-slip rubber strip 19 and the pipeline surface. The friction overcomes the resistance encountered by the pipeline during the traction process, simulating hand dragging, and moves the pipeline. If the pipeline has flanges installed beforehand, the two adjusting blocks 8 can be placed on the sides of the two pipeline flanges respectively, and the pipeline can be dragged closer together with the flanges.

[0020] The servo motor 6 is started, driving one of the adjusting screws 4 to rotate. Since the two adjusting screws 4 are fixed together by a connecting rod 5 and their threads rotate in opposite directions, they rotate synchronously. The rotation of the adjusting screw 4 drives the adjusting block 8, which is threaded to its outer side, to move along the axial direction of the screw. The movement of the adjusting block 8 is transmitted to the electric push rod 10 through the connecting plate 9, which in turn drives the traction block 11 and the pressed pipe to move together, so that the two pipes move closer to each other and achieve automatic traction alignment.

[0021] After the two pipe ends contact, the pipes are connected via flanges (for pipes without pre-installed flanges, installation can be performed within the operating chamber). The operator pulls down the rotating handle 17, causing the locking rod 15 to move downwards against the tension spring 14. The sleeve 13 slides along the sliding rod 12 to the side of the flange. Then, the rotating handle 17 is pushed, causing the locking rod 15 to slide laterally along the sleeve 13. Hex bolts are then passed through the holes in the two flanges and installed through the internal hexagonal locking groove of the locking block 16. The bolts are then tightened using the rotating handle 17, completing the pipe connection. Throughout the process, the traction block 11 maintains pressure on the pipes to prevent positional misalignment during connection.

[0022] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
