Technical Field

[0001] This utility model relates to the field of natural gas construction technology, specifically a pipeline docking device for the foundation construction of long-distance natural gas pipelines. Background Technology

[0002] Natural gas pipelines are pipelines that transport natural gas (including associated gas produced from oil fields) from extraction sites or processing plants to urban gas distribution centers or industrial users; they are also known as gas transmission pipelines.

[0003] Natural gas long-distance pipelines generally refer to main gas transmission pipelines, with an outer diameter typically ranging from 406 to 1422 mm (DN400 to DN1400). However, some shortcomings still exist in the connection and construction process of natural gas long-distance pipelines:

[0004] In the construction of long-distance natural gas pipelines, existing technologies typically use cranes to lift the pipelines, then use pads to support them before connecting the two pipelines. This method of support is very cumbersome, and different pads are required for pipelines of different diameters, making the connection of pipelines of different diameters quite inconvenient.

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] Example: Figure 1-5 As shown, this utility model provides a pipeline docking device for the foundation construction of a long-distance natural gas pipeline, including a movable base 1. The lower surface of the movable base 1 is equipped with several casters 11. By setting the casters 11, it is convenient for operators to move the device. An equipment box 2 is fixedly set on the upper surface of the movable base 1. An isolation plate 21 is fixedly set in the inner cavity of the equipment box 2. The inner cavity of the equipment box 2 is divided into a storage cavity 22 and a support cavity 23 by the isolation plate 21. By setting the storage cavity 22 and the support cavity 23, the storage cavity 22 is used for standby, and the support cavity 23 is used for supporting the natural gas pipeline. Box doors 24 are hinged on both sides of the equipment box 2. The box doors 24 are horizontally corresponding to the storage cavity 22. The storage cavity 22 is connected to the support cavity 23. A support component 3 is set in the storage cavity 22. By setting the support component 3, the support component 3 can support natural gas pipelines of different diameters, so as to facilitate the docking construction of two natural gas pipelines.

[0027] Support assembly 3 includes a plurality of loop-shaped fixing plates 31 and support rings 32. By providing a plurality of loop-shaped fixing plates 31 and support rings 32, when the loop-shaped fixing plates 31 are vertically raised or lowered, they can cause the support rings 32 to descend into the support cavity 23 or rise into the storage cavity 22. The plurality of loop-shaped fixing plates 31 are slidably disposed within the storage cavity 22. The side walls of the storage cavity 22 and the support cavity 23 are provided with a plurality of guide grooves 37. Guide grooves are fixedly provided on both sides of the loop-shaped fixing plates 31. The guide block 38 is slidably disposed on the inner wall of the guide groove 37. By setting the guide groove 37 and the guide block 38, the guide block 38 can slide vertically along the inner wall of the guide groove 37, thereby ensuring that the U-shaped fixing plate 31 and the support ring 32 slide stably and vertically within the equipment box 2. The support ring 32 is detachably installed in the U-shaped fixing plate 31. A rubber ring 33 is fixedly disposed on the inner wall of the support ring 32. By setting the support ring 32 and the rubber ring 33, the support ring 32 can support the natural gas pipeline through the rubber ring 33.

[0028] A handle 34 is fixedly installed on the upper end face of the U-shaped fixing plate 31. The handle 34 facilitates the construction personnel to pull the U-shaped fixing plate 31 and the support ring 32 vertically. Several extended screws 35 are threadedly installed on one side of the equipment box 2. Several No. 1 threaded holes 351 are provided on one side of the equipment box 2. Threaded sleeves 352 are fixedly installed at both ends of the handle 34. One end of the extended screw 35 is threadedly connected to the No. 1 threaded hole 351 and the inner wall of the threaded sleeve 352. A hexagonal seat 36 is fixedly installed at the other end of the extended screw 35. By rotating the hexagonal seat 36, the extended screw 35 can be rotated. When the thread of the extended screw 35 enters the interior of the No. 1 threaded hole 351 and the threaded sleeve 352, the U-shaped fixing plate 31 and the support ring 32 can be fixed in the storage cavity 22.

[0029] The support assembly 3 is equipped with a disassembly and assembly assembly 4, which includes a fixing rod 41. Several fixing rods 41 are arranged, with four adjacent fixing rods 41 arranged in a ring array and fixed to the inner wall of a U-shaped fixing plate 31. One end of the fixing rod 41 is fixed with a mounting plate 42, and several assembly bolts 43 are threadedly mounted on the mounting plate 42. Several second-order threaded holes 44 are provided on the outer wall of the support ring 32. One end of the assembly bolt 43 is threadedly connected to the inner wall of the second-order threaded hole 44. By setting up the mounting plate 42, the assembly bolt 43 and the second-order threaded hole 44, when the assembly bolt 43 enters the interior of the second-order threaded hole 44, the support ring 32 can be assembled into the U-shaped fixing plate 31. The support ring 32 can be disassembled or replaced by reversing the operation.

[0030] Working principle: During the connection construction of natural gas pipeline, the construction personnel first move this device (four sets of devices) to the construction position of the natural gas pipeline, then select one of the support rings 32 that are adapted to the outer diameter of the natural gas pipeline, and then rotate the corresponding hexagonal seat 36 counterclockwise, so that the extended screw 35 rotates and disengages from the first threaded hole 351 and the threaded sleeve 352. At this time, the corresponding handle 34 is released from fixation, and the corresponding U-shaped fixing plate 31 and support ring 32 descend vertically and enter the support cavity 23.

[0031] Subsequently, two support rings 32 are used to support a single natural gas pipeline, and four support rings 32 are used to support two natural gas pipelines, providing a means for construction workers to perform docking operations.

[0032] When the support ring 32 needs to be replaced, use a tool to rotate the mounting bolt 43 counterclockwise to disengage the mounting bolt 43 from the second threaded hole 44, then remove the support ring 32, place the replaced support ring 32 inside the U-shaped fixing plate 31, and rotate the mounting bolt 43 into the second threaded hole 44 to complete the replacement of the support ring 32.

[0033] All standard parts used in this invention can be purchased from the market, and irregular parts can be customized according to the description and drawings. The specific connection methods of each part adopt conventional methods such as bolts, rivets, and welding that are mature in the prior art. The machinery, parts and equipment adopt conventional models in the prior art, and the circuit connection adopts conventional connection methods in the prior art, which will not be described in detail here.

[0034] Obviously, those skilled in the art can make various modifications and variations to this utility model without departing from its spirit and scope. Therefore, if these modifications and variations fall within the scope of the claims of this utility model and their equivalents, this utility model also intends to include these modifications and variations.
