Description

Technical Field

[0001] This invention relates to the technical field of a docking device for gas pipeline installation, and more particularly to a docking device for gas pipeline installation. Background Technology

[0002] Gas is a commonly used gaseous fuel in society. It can burn to release heat for use by residents and industrial enterprises. There are many types of gas, mainly including natural gas, manufactured gas, liquefied petroleum gas (LPG), biogas, and coal gas. Compared with developed countries, my country's gas supply industry started relatively late, and the gas distributed mainly includes coal gas, LPG, and natural gas. Gas pipelines refer to the pipelines that transport gas from the extraction site or processing plant to urban gas distribution centers or industrial users; they are also called gas transmission pipelines. During installation, gas pipelines are usually laid by connecting and fixing multiple gas pipelines together.

[0003] After existing gas pipelines are fixed, due to differences in length and weight, the other end of a gas pipeline will tilt downwards under the influence of gravity after one end is fixed. At this time, the gas pipelines to be connected need to be adjusted to a concentric state to ensure a quick and effective connection. However, the existing adjustment method is generally to observe by attaching a bubble meter to the outer wall of the pipeline and adjusting while observing. The entire adjustment process is time-consuming and requires a high level of experience from the workers, making it difficult to use. Summary of the Invention

[0004] The purpose of this invention is to provide a docking device for gas pipeline installation, which features accurate positioning, high efficiency, time and labor saving, auxiliary movement, and movement linkage centering.

[0005] This invention aims to at least solve one of the technical problems existing in the prior art. This invention provides a docking device for gas pipeline installation, including an adjustment mechanism. The adjustment mechanism includes a pipe bracket, a vertical adjustment rod, a base, and a horizontal adjustment rod. The adjustment mechanism is used to adjust a first docking pipe and / or a second docking pipe. The pipe bracket is used to support the first docking pipe and / or the second docking pipe. The lower end of the pipe bracket is connected to the vertical adjustment rod, and the lower end of the vertical adjustment rod is connected to the horizontal adjustment rod. The horizontal adjustment rod is disposed on the base. The horizontal adjustment rod is used to adjust the horizontal movement of the pipe bracket, and the vertical adjustment rod is used to adjust the vertical movement of the pipe bracket.

[0006] The technical solution provided in this application also has the following technical features:

[0007] Furthermore, the first docking pipe is clamped by a first alignment mechanism, and the second docking pipe is clamped by a second alignment mechanism. The first and second alignment mechanisms each include a clamping mechanism and a moving mechanism. The clamping mechanism is linked to the moving mechanism. When the axes of the first and second docking pipes are aligned, the clamping mechanism unlocks the moving mechanism, and the moving mechanism moves the first or second docking pipe to reduce the distance between them. If the axes of the first and second docking pipes are not aligned, the clamping mechanism locks the moving mechanism, preventing it from moving.

[0008] Furthermore, the clamping mechanism includes an alignment ring, a hinge plate, a stop plate, a telescopic rod, a spring, and a support plate. The stop plate is located at the outer end of the telescopic rod, and the spring is installed on the telescopic rod. The hinge plate, telescopic rod, support plate, and telescopic rod are sequentially hinged to form a parallel linkage mechanism, which consists of four rings arranged in an array on the alignment ring. The support plate is used to abut against the connecting pipe, and the hinge plate is hinged to the outside of the alignment ring via a hinge sleeve.

[0009] Furthermore, the moving mechanism includes a rotating ring, an external gear ring, a sliding frame, support legs, a limiting plate, and traveling wheels; the support legs are connected to the sliding frame, there are two sliding frames, and the rotating ring is located between the two sliding frames; the traveling wheels are connected to the limiting plate, and the limiting plate is fixedly connected to the lower end of the sliding frame; the traveling wheels are screwed onto a lead screw, and the lead screw is fixed to a bracket; the rotating ring engages with the traveling wheels through the external gear ring; the inner surface of the rotating ring is provided with a locking module, and the locking module is equipped with a stop plate. The rotating ring is locked and unlocked by the linkage of the stop plate and the locking module, so that it cannot rotate and can rotate freely.

[0010] Furthermore, the clamping mechanism is installed within the moving mechanism via a sliding frame and a fixed plate.

[0011] Furthermore, the locking module is a groove or a protrusion.

[0012] Furthermore, the hinge sleeve is T-shaped.

[0013] Furthermore, the alignment ring is provided with an elliptical groove for the telescopic rod and spring to move up and down.

[0014] Furthermore, both ends of the telescopic rod are provided with hinge shafts, and a stop plate is provided on the hinge shaft at the outer end.

[0015] Furthermore, pads are provided at both ends of the spring.

[0016] Furthermore, the alignment ring is composed of spliced ​​components, specifically four continuously spliced ​​parts.

[0017] Furthermore, after the pipe to be docked is inserted into the alignment mechanism, multiple support plates abut against the surface of the pipe. If the axis of the pipe and the alignment mechanism do not coincide, the stop plate on the hinge plate will extend into the locking module of the rotating ring, preventing the rotating ring from rotating. After the adjustment mechanism adjusts the pipe to be docked to coincide with the axis of the alignment mechanism, the rotating ring rotates normally, driving the traveling wheel to rotate through the external gear ring. The traveling wheel meshes with the screw at its center, driving the alignment mechanism to move for docking and installation. The two pipe brackets of the adjustment mechanism support the pipe, and the relative position of the pipe to be docked and the alignment mechanism can be adjusted by the vertical adjustment rod and the horizontal adjustment rod respectively, so that it coincides with the axis of the alignment mechanism.

[0018] Brief working process of this application:

[0019] After the pipe to be docked is inserted into the alignment mechanism, multiple support plates abut against the surface of the pipe to be docked. If the axis of the pipe and the alignment mechanism do not coincide, the stop plate on the hinge plate will extend into the locking module between the rotating ring, preventing the rotating ring from rotating. After the adjustment mechanism is adjusted to make the axis of the pipe to be docked coincide with the axis of the alignment mechanism, the rotating ring will rotate normally, driving the traveling wheel to rotate through the external gear ring. The traveling wheel meshes with the screw at its center, driving the alignment mechanism to move for docking and installation.

[0020] The two pipe supports of the adjustment mechanism support the pipe, and the relative position of the pipe to be docked and the alignment mechanism can be adjusted by the vertical adjustment rod and the horizontal adjustment rod respectively, so that the pipe coincides with the axis of the alignment mechanism.

[0021] The pipe to be connected refers to a fixed pipe that is already installed at one end. After being inserted into the alignment mechanism, the alignment mechanism can be adjusted to make the axis of the fixed pipe coincide with the axis of the alignment mechanism. The other end is a movable pipe to be installed. By adjusting the mechanism, the axis of the pipe is made to coincide with the axis of the alignment mechanism, and then the connection can be made.

[0022] The present invention has the following beneficial effects, which can be summarized in the following points in conjunction with specific technical means:

[0023] 1. The adjustment mechanism of the present invention is used to adjust the first docking pipe and / or the second docking pipe, realizing horizontal and vertical adjustment to achieve centering between the first docking pipe and the second docking pipe; laying the foundation for the next clamping movement. Of course, it is also possible to move first and then center; or center first and then move, depending on the site conditions.

[0024] 2. The clamping mechanism and moving mechanism of the present invention are mainly used to clamp and move the objects to be adjusted, the first docking pipe and the second docking pipe. This is achieved in two ways: the clamping mechanism is linked to the moving mechanism, and the moving mechanism moves by means of a lead screw. The clamping mechanism is linked to the moving mechanism by means of a locking mechanism. When the two pipes are aligned, the clamping mechanism unlocks the moving mechanism, and the moving mechanism moves the pipes closer to each other. When the pipes are not aligned, the moving mechanism stops and cannot move closer. Attached Figure Description

[0039] like Figure 1-9 As shown:

[0040] Example 1

[0041] A gas pipeline installation docking device includes an adjustment mechanism 24, which comprises a pipe bracket 23, a vertical adjustment rod 28, a base 29, and a horizontal adjustment rod 30. The adjustment mechanism 24 is used to adjust a first docking pipe 20 and / or a second docking pipe 21. The pipe bracket 23 is used to support the first docking pipe 20 and / or the second docking pipe 21. The lower end of the pipe bracket 23 is connected to the vertical adjustment rod 28, and the lower end of the vertical adjustment rod 28 is connected to the horizontal adjustment rod 30. The horizontal adjustment rod 30 is mounted on the base 29. The horizontal adjustment rod 30 is used to adjust the horizontal movement of the pipe bracket 23, and the vertical adjustment rod 28 is used to adjust the vertical movement of the pipe bracket 23.

[0042] When this application is implemented, the working principle or process is as follows: the pipe rack 23 is adjusted by the adjustment mechanism 24, mainly the horizontal displacement and the height displacement. The pipe alignment can be achieved by adjusting these two dimensions.

[0043] Example 2

[0044] The first docking pipe 20 is clamped by a first alignment mechanism 19, and the second docking pipe 21 is clamped by a second alignment mechanism 22. The first alignment mechanism 19 and the second alignment mechanism 22 include a clamping mechanism and a moving mechanism. The clamping mechanism is linked to the moving mechanism. When the axes of the first docking pipe 20 and the second docking pipe 21 are aligned, the clamping mechanism unlocks the moving mechanism, and the moving mechanism moves the first docking pipe 20 or the second docking pipe 21 to reduce the distance between them. When the axes of the first docking pipe 20 and the second docking pipe 21 are not aligned, the clamping mechanism locks the moving mechanism, preventing it from moving.

[0045] Unlike the above embodiments, in this embodiment, the clamping mechanism and the moving mechanism are linked. After the two pipes are aligned using the adjustment mechanism, the clamping mechanism is used to determine whether the pipes are aligned. Only when they are aligned can the moving mechanism move the pipes closer to each other. The structure is simple, the cost is low, and the effect is good.

[0046] Example 3

[0047] The clamping mechanism includes an alignment ring 9, a hinge plate 12, a stop plate 13, a telescopic rod 14, a spring 15, and a support plate 16. The stop plate 13 is located at the outer end of the telescopic rod 14, and the spring 15 is installed on the telescopic rod 14. The hinge plate 12, the telescopic rod 14, the support plate 16, and the telescopic rod 14 are sequentially hinged to form a parallel linkage mechanism, which consists of four rings arranged in an array on the alignment ring 9. The support plate 16 is used to abut against the connecting pipe, and the hinge plate 12 is hinged to the outside of the alignment ring 9 via a hinge sleeve 18.

[0048] Unlike the above embodiments, in this embodiment, after the pipe to be docked is inserted into the alignment mechanism, multiple support plates 16 abut against the surface of the pipe to be docked. If the axis of the pipe and the alignment mechanism do not coincide, the stop plate on the hinge plate 12 will extend into the locking module 11 of the rotating ring 1, preventing the rotating ring 1 from rotating. After the adjustment mechanism 24 adjusts the pipe to be docked to coincide with the axis of the alignment mechanism, the rotating ring 1 rotates normally, and drives the traveling wheel 8 to rotate through the external gear ring 2. The traveling wheel 8 meshes with the screw at its center, driving the alignment mechanism to move for docking and installation.

[0049] The two pipe supports 23 of the adjustment mechanism 24 support the pipe, and the relative position of the pipe to be docked and the alignment mechanism can be adjusted by the vertical adjustment rod 28 and the horizontal adjustment rod 30 respectively, so that the pipe coincides with the axis of the alignment mechanism.

[0050] The pipe to be connected refers to a fixed pipe that has been installed at one end. After being inserted into the alignment mechanism, the alignment mechanism can be adjusted to make the axis of the fixed pipe coincide with the axis of the alignment mechanism. The other end is a movable pipe to be installed. By adjusting mechanism 24, the axis of the pipe can be made to coincide with the axis of the alignment mechanism, and then the connection can be made.

[0051] Example 4

[0052] The moving mechanism includes a rotating ring 1, an external gear ring 2, a sliding frame 3, support legs 6, a limiting plate 7, and traveling wheels 8. The support legs 6 are connected to the sliding frame 3, and there are two sliding frames 3, with the rotating ring 1 positioned between the two sliding frames 3. The traveling wheels 8 are connected to the limiting plate 7, which is fixedly connected to the lower end of the sliding frame 3. The traveling wheels 8 are screwed onto a lead screw 5, which is fixed to a bracket 4. The rotating ring 1 engages with the traveling wheels 8 through the external gear ring 2. The inner surface of the rotating ring 1 is provided with a locking module 11, which is matched with a stop plate 13. The rotating ring 1 is locked and unlocked by the stop plate 13 and the locking module 11, making it unable to rotate but able to rotate freely.

[0053] Unlike the above embodiments, in this embodiment, the moving mechanism and the clamping mechanism are linked, and the moving pipes move closer to each other. The structure is simple and the design is ingenious. With the help of the adjustment mechanism, the pipes can move closer together when aligned.

[0054] Example 5

[0055] The clamping mechanism is installed inside the moving mechanism via a sliding frame 3 and a fixed plate 10; this structure meets practical application requirements, is compact, easy to implement, and low in cost.

[0056] The locking module 11 is a groove or a protrusion; it has a simple structure, is flexible in implementation, easy to set up, low in cost, and reliable in locking.

[0057] The hinge sleeve 18 is T-shaped; its structure is simple and compact, and it works well with this structure to achieve the structural function of this application.

[0058] The alignment ring 9 is provided with an elliptical groove for the telescopic rod 14 and the spring 15 to move up and down; the spring 15 is used to achieve reset, and the telescopic rod 14 effectively engages and resists when aligned, and effectively stops when misaligned;

[0059] The telescopic rod 14 is provided with hinge shafts at both ends, and a stop plate 13 is provided on the hinge shaft at the outer end; the structure is flexible, easy to install, and the locking structure is reliable.

[0060] The spring 15 is provided with pads at both ends to reduce wear and friction, and at the same time to prevent the ends of the spring 15 from getting stuck or damaging other parts.

[0061] The alignment ring 9 is composed of spliced ​​components, specifically four consecutive spliced ​​parts. This structure allows for good interchangeability of components and is convenient to use with the locking mechanism.

[0062] Example 6

[0063] After the pipe to be docked is inserted into the alignment mechanism, multiple support plates 16 abut against the surface of the pipe to be docked. If the axis of the pipe and the alignment mechanism do not coincide, the stop plate on the hinge plate 12 will extend into the locking module 11 of the rotating ring 1, preventing the rotating ring 1 from rotating. After the adjustment mechanism 24 adjusts the pipe to be docked to coincide with the axis of the alignment mechanism, the rotating ring 1 rotates normally, driving the traveling wheel 8 to rotate through the external gear ring 2. The traveling wheel 8 meshes with the screw at its center, driving the alignment mechanism to move for docking and installation. The two pipe brackets 23 of the adjustment mechanism 24 support the pipe, and the relative position of the pipe to be docked and the alignment mechanism can be adjusted by the vertical adjustment rod 28 and the horizontal adjustment rod 30 respectively, so that it coincides with the axis of the alignment mechanism.

[0064] After the pipe to be docked is inserted into the alignment mechanism, multiple support plates 16 abut against the surface of the pipe to be docked. If the axis of the pipe and the alignment mechanism do not coincide, the stop plate on the hinge plate 12 will extend into the locking module 11 of the rotating ring 1, making the rotating ring 1 unable to rotate. After the adjustment mechanism 24 adjusts the pipe to be docked to coincide with the axis of the alignment mechanism, the rotating ring 1 rotates normally, and drives the traveling wheel 8 to rotate through the external gear ring 2. The traveling wheel 8 meshes with the screw at its center, driving the alignment mechanism to move for docking and installation.

[0065] The two pipe supports 23 of the adjustment mechanism 24 support the pipe, and the relative position of the pipe to be docked and the alignment mechanism can be adjusted by the vertical adjustment rod 28 and the horizontal adjustment rod 30 respectively, so that the pipe coincides with the axis of the alignment mechanism.

[0066] The pipe to be connected refers to a fixed pipe that is already installed at one end. After being inserted into the alignment mechanism, the alignment mechanism can be adjusted to make the axis of the fixed pipe coincide with the axis of the alignment mechanism. The other end is a movable pipe to be installed. By adjusting mechanism 24, the axis of the pipe can be made to coincide with the axis of the alignment mechanism, and then the connection can be made.
