Description

Technical Field

[0001] The utility model belongs to the technical field of pipeline construction, in particular to a pipeline plugging auxiliary structure. Background Art

[0002] Pipeline construction refers to the project of connecting the pipeline starting station, intermediate station and terminal station with pipes, pipe fittings, valves, etc. to form a pipeline transportation route, including pipeline assembly and laying, installation of pipeline valves and pipe fittings, and is divided into open pipe construction and concealed pipe construction. Open pipe construction is to erect the pipeline on a prefabricated support device and expose it to the outside world. This is an open pipe. Concealed pipe construction is to dig a trench on the ground, bury the pipeline inside the trench and then backfill it. This is concealed pipe construction.

[0003] When constructing concealed pipelines, existing pipelines generally adopt a plug-in setting, that is, one end of the pipeline is a male head and the other end is a female head. The female head is larger and has a groove inside the female head. A sealing ring can be placed inside the groove. The male head is inserted into the female head to achieve a sealed connection of the pipeline. During construction, the male head needs to be cleaned and lubricating oil is applied to the male head and the inner surface of the sealing ring to avoid excessive friction that causes the sealing ring to fall out.

[0004] During existing construction, the pipeline is usually lifted by an excavator or other lifting device, and the construction workers manually insert the pipeline. During this period, if the size deviation between the male and female ends is too large, the foreman will impact the sealing ring, causing the sealing ring to fall out of the sealing groove. Therefore, it seems that the male and female ends have been successfully connected, but in fact the sealing ring has been separated from its original position and cannot play a sealing role, which will cause rework.

[0005] Therefore, it is necessary to design a structure that can assist in the insertion of pipes to support the movement of the pipes, make the pipes as stable as possible, and improve the insertion efficiency. Utility Model Content

The two clamps 4 are put on the tail end of the pipe, and then the two sliding members 3 are moved toward each other. At this time, the locking bolt 301 is inserted into the threaded groove 302 and tightened, so that the two sliding members 3 are tightly connected, and an auxiliary structure for guiding the pipe plug-in is installed above the clamp 4;

[0025] The auxiliary structure includes: a connecting recess 401, a guide plate 5, and a guide wheel 502. The connecting recess 401 is integrally provided on the side below the clamp 4. The connecting recess 401 is fixed with the guide plate 5 by bolts. The inner edge of the guide plate 5 is connected to the guide wheel 502 for rotation. The number of guide wheels 502 is at least three and they are arranged in parallel and symmetrically. The hoisted pipe is placed on the guide plate 5. The guide wheel 502 supports and guides the pipe. The hoisted pipe is supported by the guide wheel 502 and enters the tail end to complete the plugging.

[0026] The guide plate 5 is provided with a support assembly that can provide stability;

[0027] The support assembly includes a screw 501 and a handle 5011 . The screw 501 is threadedly connected to the outer edge of the guide plate 5 , and the handle 5011 is integrally provided on the top of the screw 501 .

[0028] The sliding member 3 and the clamp 4 are arranged in a concave-convex manner and are connected through bolts. With this connection method, the clamp 4 can be replaced.

[0029] Among them, the angle between the screw 501 and the guide plate 5 is 75°, and the number of screws 501 is at least two.

[0030] Reference Figure 4-5 ,

[0031] Example 2: In addition to the above embodiment, there is another embodiment of the support assembly, which includes

[0032] Furthermore, the movable rod 6, the support plate 601, the oblique teeth 602, the limiting cavity 7, and the clamping block 701 are connected to the movable rod 6 by sliding on the guide plate 5 through a sliding groove, and the bottom of the movable rod 6 is rotatably connected to the support plate 601 through a spherical shaft. The bottom of the support plate 601 is provided with a nail, and the side of the support plate 601 is integrated with the oblique teeth 602. The guide plate 5 is provided with a limiting cavity 7 on the side of the sliding groove. The inside of the limiting cavity 7 is connected to the clamping block 701 through a spring, and the handle of the clamping block 701 extends out of the limiting cavity 7.

[0033] The block 701 and the beveled teeth 602 are supported in a one-way engagement. When the guide plate 5 needs to be supported, the movable rod 6 is pressed down, and the beveled teeth 602 contact the bevel surface of the block 701 without engagement. The nails set at the bottom of the support plate 601 are inserted into the bottom surface and cooperate with the spherical rotating shaft to form a support. The beveled teeth 602 engage with the block 701, and the movable rod 6 cannot move in the opposite direction, thereby dispersing the pressure on the pipeline. When the movable rod 6 needs to be moved upward, the block 701 is pulled by the handle to release the engagement between the beveled teeth 602 and the block 701, and the movable rod 6 can be moved upward at this time.

[0034] Compared with the first embodiment, this design can provide better stability and be more convenient to use when the nails set at the bottom of the support plate 601 are inserted into the bottom surface. At the same time, combined with the spherical shaft, it can adapt to different uneven ground surfaces.

[0035] Working principle: First, put the two clamps 4 on the female end of the pipe, and then move the two sliding parts 3 toward each other. At this time, insert the locking bolt 301 into the thread groove 302 and tighten it to connect the two sliding parts 3 tightly. At this time, install the guide plate 5 on the clamp 4 through the bolt, and then rotate the handle 5011 to move the screw 501 and insert it between the ground to form a support. The angle between the screw 501 and the guide plate 5 is 75°, and the number of screws 501 is at least two. This design can disperse the downward force and improve the support strength. Of course, the second embodiment can also be used. The block 701 and the bevel tooth 602 support are arranged in a one-way bite, which is required. When supporting the guide plate 5, the movable rod 6 is pressed down, and the oblique teeth 602 contact the oblique surface of the block 701 without biting. The nails set at the bottom of the support plate 601 are inserted into the bottom surface and cooperate with the spherical shaft to form a support. The oblique teeth 602 are engaged with the block 701, and the movable rod 6 cannot move in the opposite direction, thereby dispersing the pressure on the pipeline. When the movable rod 6 needs to be moved upward, the block 701 is pulled by the handle to release the engagement between the oblique teeth 602 and the block 701. At this time, the movable rod 6 can be moved upward, and then the male end of the hoisted pipe is placed on the guide plate 5. The guide wheel 502 supports and guides the pipe. The hoisted pipe enters the tail end with the support of the guide wheel 502 to complete the plug-in.

[0036] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent replacements and improvements made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
