DETAILED DESCRIPTION

[0017] In order to make the purpose, scheme and advantages of the utility model more clearly and clearly, the utility model is further explained in detail below, the utility model is explained only for explaining the utility model, and does not be regarded as the limitation of the utility model.

Thus, the appearances of the phrases "in one embodiment", "in an embodiment", "in one example" or "in an example" in various places throughout this specification are not necessarily all referring to the same embodiment or example.

[0021] Embodiment one provides a kind of pipeline side-by-side connection assembly, comprising: base 1, first sliding assembly 2, second sliding assembly 3 and bidirectional screw rod 4;The first sliding assembly 2 is set in the top of the base 1, the first sliding assembly 2 with the base 1 sliding connection, the first sliding assembly 2 top is provided with first pipeline connector 5;Second sliding assembly 3 is set in the top of the base 1, the second sliding assembly 3 with the base 1 sliding connection, the first sliding assembly 2 with the second sliding assembly 3 opposite setting, the second sliding assembly 3 top is provided with second pipeline connector 6;The bidirectional screw rod 4 includes rotating part 401, first screw part 402 and second screw part 403, the rotating part 401, first screw part 402, second screw part 403 are sequentially connected, the first screw part 402 with the first sliding assembly 2 is connected, the second screw part 403 with the second sliding assembly 3 is connected.

[0022] In the implementation process, the operator uses a wrench or a special rotating tool to act on the rotating part 401 of the bidirectional threaded screw rod 4. When the rotating part 401 is rotated clockwise, the first threaded part 402 is connected with the first sliding assembly 2 through the thread, the second threaded part 403 is connected with the second sliding assembly 3 through the thread, and the rotation directions of the threads are opposite. According to the thread transmission principle, the first sliding assembly 2 and the second sliding assembly 3 move towards each other. This makes the distance between the first pipe connecting piece 5 and the second pipe connecting piece 6 mounted on the two sliding assemblies gradually decrease. Conversely, when the rotating part 401 is rotated counterclockwise, the two sliding assemblies move away from each other, and the distance between the pipe connecting pieces increases. When the appropriate connection position is reached, stop rotating the bidirectional threaded screw rod 4, and place the two pipes to be connected in the clamps of the first pipe connecting piece 5 and the second pipe connecting piece 6 for fixation.

[0023] By way of reference, in a possible implementation, the first sliding assembly 2 includes a first sliding seat 201 and a first screw nut, the first sliding seat 201 is provided with a first through hole 203, the first screw nut is arranged in the first through hole 203, and the first screw nut is connected with the first threaded part 402. The second sliding assembly 3 includes a second sliding seat 301 and a second screw nut, the second sliding seat 301 is provided with a second through hole 303, the second screw nut is arranged in the second through hole 303, and the second screw nut is connected with the second threaded part 403.

[0024] In the implementation process, the first threaded part 402 of the bidirectional threaded screw rod 4 is connected with the first screw nut in the first sliding assembly 2, the second threaded part 403 is connected with the second screw nut in the second sliding assembly 3, and the rotation directions of the two threaded parts are opposite. When the rotating part 401 is rotated clockwise, the first screw nut drives the first sliding seat 201 to move along the slide rail 7 on the base 1 towards the second sliding assembly 3, and at the same time, the second screw nut drives the second sliding seat 301 to move along the slide rail 7 towards the first sliding assembly 2, so that the first sliding assembly 2 and the second sliding assembly 3 move towards each other, and the distance between the two pipes gradually decreases. Conversely, when the rotating part 401 is rotated counterclockwise, the first sliding assembly 2 and the second sliding assembly 3 move away from each other, and the distance between the two pipes increases.

[0025] By way of reference, the base 1 is provided with an opening at the top, the base 1 is provided with a slide rail 7, the slide rail 7 is provided with a first sliding block 8 and a second sliding block 9, the top of the first sliding block 8 is connected with the first sliding seat 201, and the top of the second sliding block 9 is connected with the second sliding seat 301.

[0026] In the specific implementation process, the base 1 is placed on a stable work plane, and the top opening of the base 1 facilitates the installation and operation of the internal components. A length-adapted slide rail 7 is installed in advance inside the base 1, and the installation of the slide rail 7 is stable and horizontal. The first sliding assembly 2 and the second sliding assembly 3 are prepared, wherein the first sliding assembly 2 comprises a first sliding seat 201 and a first screw nut installed inside the first sliding seat 201, and the second sliding assembly 3 comprises a second sliding seat 301 and a second screw nut installed inside the second sliding seat 301. The first sliding block 8 is installed at one end of the slide rail 7, the second sliding block 9 is installed at the other end of the slide rail 7, and then the first sliding seat 201 and the second sliding seat 301 are fixed on the top of the corresponding first sliding block 8 and second sliding block 9 respectively, so as to ensure firm connection and enable the first sliding assembly 2 and the second sliding assembly 3 to smoothly slide on the slide rail 7. The operator uses a wrench or a special tool to act on the rotating part 401 of the bidirectional threaded screw rod 4. Since the first threaded part 402 of the bidirectional threaded screw rod 4 cooperates with the first screw nut of the first sliding assembly 2, the second threaded part 403 cooperates with the second screw nut of the second sliding assembly 3, and the rotation directions of the two threaded parts are opposite. When the rotating part 401 is rotated clockwise, the first screw nut drives the first sliding seat 201, and then drives the first sliding block 8 connected thereto to move along the slide rail 7 towards the second sliding assembly 3; at the same time, the second screw nut drives the second sliding seat 301 and the second sliding block 9 to move along the slide rail 7 towards the first sliding assembly 2, so that the first sliding assembly 2 and the second sliding assembly 3 approach each other, and the distance between the two pipes gradually decreases. Conversely, when the rotating part 401 is rotated counterclockwise, the first sliding assembly 2 and the second sliding assembly 3 move away from each other, and the distance between the two pipes increases.

[0027] In a possible implementation, a rotating disc 11 is further included, and the rotating disc 11 is connected with the rotating part 401 of the bidirectional threaded screw rod 4 through the shaft coupling 10.

[0028] In the specific implementation process, when it is necessary to adjust the distance between the pipes, the operator directly rotates the rotating disc 11. Since the rotating disc 11 is connected with the rotating part 401 of the bidirectional threaded screw rod 4 through the shaft coupling 10, the shaft coupling 10 can ensure synchronous rotation of the two, so that the rotation of the rotating disc 11 drives the rotating part 401 of the bidirectional threaded screw rod 4 to rotate. When the rotating disc 11 is rotated clockwise, the first threaded part 402 of the bidirectional threaded screw rod 4 drives the first sliding assembly 2 connected thereto to approach the second sliding assembly 3 along the slide rail 7, and at the same time, the second threaded part 403 drives the second sliding assembly 3 to approach the first sliding assembly 2 along the slide rail 7, so as to reduce the distance between the first and second pipe connectors 6 and achieve the reduction of the distance between the two pipes; conversely, when the rotating disc 11 is rotated counterclockwise, the distance between the two pipes increases. The operator can stop rotating the rotating disc 11 and the bidirectional threaded screw rod 4 by observing the position and distance of the pipes and combining the actual demand when the appropriate connection position is reached.

[0029] In one possible implementation, the first pipe connector 5 is provided with a first connecting hole (not shown in the figure) that is adapted to the outer diameter of the first pipe. The inner wall of the first connecting hole is provided with internal threads (not shown in the figure) for threaded connection with the externally threaded end of the first pipe. The second pipe connector 6 is provided with a second connecting hole (not shown in the figure) that is adapted to the outer diameter of the second pipe. The inner wall of the second connecting hole is provided with internal threads (not shown in the figure) for threaded connection with the externally threaded end of the second pipe.

[0030] By way of reference, the first pipe connector 5 and the second pipe connector 6 can be threaded pipe connectors, such as threaded straight-through pipe joints. In the specific implementation, the externally threaded end of the first pipe is slowly screwed into the first connecting hole of the first pipe connector 5. The pipe is rotated clockwise to gradually deepen the pipe into the connecting hole by means of the engagement of the threads. During the rotation, attention should be paid to keeping the axial position of the pipe correct to avoid skewing that can cause damage to the threads or loose connection. In the same way, the externally threaded end of the second pipe is screwed into the second connecting hole of the second pipe connector 6, and the connection is made by rotating clockwise. At the initial stage of the connection, the threads should not be fully tightened, and a certain degree of looseness should be maintained to allow subsequent fine adjustment of the position and angle of the pipes. In the same way as before, the position of the first sliding assembly 2 and the second sliding assembly 3 is adjusted by rotating the rotating part 401 of the bidirectional threaded screw rod 4, thereby changing the distance between the two pipes. During the adjustment, the position and distance of the pipes are observed to ensure that the connection requirements are met. When the appropriate connection position is reached, the rotation of the bidirectional threaded screw rod 4 is stopped. At this time, the first pipe and the second pipe are further tightened using a tool (such as a pipe wrench, etc.) to make the threaded connection between the pipes and the pipe connectors tight, ensure the connection is firm, and prevent problems such as leakage, and finally complete the parallel connection of the pipes.

[0031] In another possible implementation, the first pipe connector 5 and the first pipe can be connected by flanges, and the second pipe connector 6 and the second pipe can also be connected by flanges.

[0032] By way of reference, the first pipe connector 5 and the second pipe connector 6 can be integral flange connectors, which are integrally formed by a flange and a connecting body. The material is mostly carbon steel or stainless steel. The connecting body part is fixed with the sliding assemblies on the base 1, and the flange has uniformly distributed bolt holes that can be tightly connected with the mating flange on the end of the pipe by bolts.

[0033] In the implementation process, the first pipeline and the second pipeline are prepared with matched carbon steel flanges, the sizes of which are consistent with the flanges of the integral flange connector, the matched flanges are welded at the end of the first pipeline and the second pipeline, the welding is firm and the flanges are perpendicular to the axis of the pipeline, the first pipeline and the second pipeline with the welded flanges are respectively placed near the integral flange connector on the top of the first sliding assembly 2 and the second sliding assembly 3, the bolt holes of the two flanges are preliminarily aligned, the sealing gasket is placed between the two flanges when the bolt holes of the two flanges are completely aligned, then the bolts are sequentially inserted into the bolt holes of the two flanges, and the nuts are tightened.

[0034] Embodiment two provides a gas pipeline assembly, which comprises the pipeline side-by-side connection assembly described in embodiment one.

[0035] The above-described embodiments only express the specific implementation manners of the present application, the description is relatively specific and detailed, but it cannot be understood as the limitation of the patent scope of the present application. It should be noted that, for the ordinary skilled in the art, without departing from the concept of the present application, a number of modifications and improvements can be made, which all belong to the protection scope of the present application.
