Technical Field

[0001] This utility model relates to the field of gas engineering construction equipment technology, and in particular to a pipeline transportation device for gas engineering. Background Technology

[0002] Gas engineering refers to the sum of a series of engineering and technical activities surrounding the production, storage, transmission, distribution, application, and construction, maintenance, and management of related facilities for gas. It covers the entire process from the extraction or preparation of gas resources such as natural gas, manufactured gas, and liquefied petroleum gas, through storage and transportation via pipelines, storage tanks, and other facilities, to delivery to end users such as residential users, industrial enterprises, and commercial premises via pressure regulation and metering. It also includes related safety protection, system control, and equipment maintenance. Its core is to ensure the safe, stable, and efficient supply of gas to meet the needs of social production and daily life for gas energy.

[0003] In gas engineering construction, pipeline transportation is a key link, requiring the handling of short-distance transfer needs for gas pipelines of different lengths and diameters (such as PE pipes and steel pipes). Traditional pipeline transportation devices are mostly fixed-length flatbed trolleys or brackets. The fixed-length design cannot accommodate pipelines of different lengths. When transporting short pipes, the redundant space can easily cause the pipes to shake and collide. When transporting long pipes, the device length is insufficient, requiring manual assistance to lift them, which increases labor intensity and poses safety hazards. Therefore, a pipeline transportation device for gas engineering is proposed to solve the above problems. Utility Model Content

[0004] To overcome the above shortcomings, this utility model provides a pipeline transportation device for gas engineering, which aims to solve the problem that in the prior art, fixed-length trolleys cannot adapt to pipelines of different lengths, making transportation more troublesome.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a pipeline transportation device for gas engineering, comprising a hollow plate, wherein an extension mechanism is provided on the inner side of the hollow plate;

[0006] The extension mechanism includes a bidirectional threaded rod that penetrates and is rotatably connected to the inner wall of the hollow plate.

A support mechanism is provided on the top of the hollow plate.

[0008] The guide includes a guide post slidably connected to the inner wall of the sliding block, and the outer wall of the guide post is fixedly connected to the inner wall of the connecting empty plate.

[0009] As a further description of the above technical solution:

[0010] A connecting hole is provided at the right end of the hollow plate, and the outer arc surface of the limiting post is consistent with the inner diameter of the connecting hole.

[0011] As a further description of the above technical solution:

[0012] The inner wall of the fixing block is fixedly connected to the inner wall of the circular plate by bolts.

[0013] As a further description of the above technical solution:

[0014] The height of the sliding block is the same as the height of the inner wall of the hollow plate, and the height of the moving block is the same as the height of the inner wall of the hollow plate.

[0015] As a further description of the above technical solution:

[0016] The support mechanism includes a support plate fixedly connected to the top of the hollow plate. A placement plate and a fixing plate are fixedly connected to the top of the hollow plate respectively. Pressure plates are slidably connected to the inner walls of the support plate, placement plate and fixing plate. A threaded rod is rotatably connected to the inner wall of the pressure plate. The bottom of the threaded rod is threadedly connected to the protruding inner wall of the side of the support plate.

[0031] 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.

[0032] Reference Figures 1-2One embodiment of this utility model is a pipeline transportation device for gas engineering, which includes a hollow plate 1 and an extension mechanism 3 provided on the inner side of the hollow plate 1. The extension mechanism 3 allows the length of the overall pipeline transportation device to change, thereby adapting to pipelines of different lengths.

[0033] Reference Figures 2-4 The extension mechanism 3 includes a bidirectional threaded rod 304 that passes through and is rotatably connected to the inner wall of the hollow plate 1. A movable block 303 is threadedly connected to the outer wall of the bidirectional threaded rod 304. Two sets of movable blocks 303 are provided, and the rotation of the bidirectional threaded rod 304 causes the two sets of movable blocks 303 to move closer or further apart synchronously. An X-shaped connecting frame 301 is hinged to the right side of each movable block 303. The two sets of movable blocks 303 are hinged to the left side of the X-shaped connecting frame 301. When the two sets of movable blocks 303 move inward, the overall length of the X-shaped connecting frame 301 increases, and vice versa. A sliding block 306 is hinged to the right end of the X-shaped connecting frame 301. Two sets of sliding blocks 306 are provided, and their movement trajectory is consistent with the movement trajectory of the two sets of movable blocks 303. A guide is provided on the inner wall of the sliding block 306, which provides support and guidance. A connecting hollow plate is fixedly connected to the outer wall of the guide. 2. The overall length of the hollow plate 1 and the connecting hollow plate 2 can be adjusted by the extension mechanism 3 to accommodate pipes of different lengths. Both the hollow plate 1 and the connecting hollow plate 2 are equipped with lockable casters at the bottom. The interior of both plates is hollow to protect the X-shaped connecting frame 301. The left end of the connecting hollow plate 2 is fixedly connected to a limit post 302, which supports the folded hollow plate 1 and the connecting hollow plate 2. The front end of the bidirectional threaded rod 304 is fixedly connected to a circular plate 305. The rotation of the circular plate 305 controls the synchronous movement of the bidirectional threaded rod 304. The upper part of the hollow plate 1 is fixedly connected to a fixing block 308, and bolts are provided on the inner wall of the fixing block 308. The top of the hollow plate 1 is equipped with a support mechanism 4, which supports the pipes and prevents them from piling up.

[0034] Reference Figures 2-4The guide component includes a guide post 307 slidably connected to the inner wall of the sliding block 306. The outer wall of the guide post 307 is fixedly connected to the inner wall of the connecting hollow plate 2. The guide post 307 supports the sliding block 306 in the moving state. A connecting hole is opened at the right end of the hollow plate 1. The outer arc surface of the limiting post 302 is consistent with the inner diameter of the connecting hole. When the hollow plate 1 and the connecting hollow plate 2 are folded, the connecting hole and the limiting post 302 are inserted to support the folded whole and prevent the connecting hollow plate 2 and the hollow plate 1 from vertically misaligning after folding. The inner wall of the fixing block 308 is fixedly connected to the inner wall of the circular plate 305 by bolts. The outer arc surface of the circular plate 305 is provided with multiple sets of screw holes to facilitate connection with bolts. The height of the sliding block 306 is consistent with the height of the inner wall of the hollow plate 1, and the height of the moving block 303 is consistent with the height of the inner wall of the hollow plate 1. The consistent height prevents rotation during movement.

[0035] Reference Figures 3-5 The support mechanism 4 includes a support plate 401 fixedly connected to the top of the hollow plate 1. A placement plate 402 and a fixing plate 403 are fixedly connected to the top of the hollow plate 1, respectively. The heights of the support plate 401, placement plate 402, and fixing plate 403 increase sequentially. A pressure plate 405 is slidably connected to the inner walls of the support plate 401, placement plate 402, and fixing plate 403. The pressure plate 405 can clamp and fix the pipe. A threaded rod 404 is rotatably connected to the inner wall of the pressure plate 405. The bottom of the threaded rod 404 is threadedly connected to the inner wall of the side protrusion of the support plate 401. The threaded rod 404 is connected to the inner wall of the side protrusion of the fixing plate 403. The screw rod 404 can move up and down inside the protrusion, allowing the height of the pressure plate 405 to be adjusted to accommodate pipes of different diameters. The lower part of the pressure plate 405 has a semi-circular opening, and the top of the support plate 401, the placement plate 402, and the fixing plate 403 also have semi-circular openings. The semi-circular openings facilitate pipe placement. The bottom of the fixing plate 403 and the placement plate 402 both have round holes, the center of which corresponds to the center of the semi-circular opening of the support plate 401. The round holes facilitate horizontal installation of pipes. There are two sets of support plates 401, placement plates 402, and fixing plates 403, with the other set fixed to the connecting empty plate 2.

[0036] Working principle: When the whole unit needs to be unfolded for use, first release the bolt limit, then rotate the circular plate 305 to drive the bidirectional threaded rod 304 to rotate, so that the two sets of moving blocks 303 on the inner wall of the hollow plate 1 move closer together, thereby driving the X-shaped connecting frame 301 hinged to it to extend and retract. The sliding block 306 at the right end of the X-shaped connecting frame 301 slides along the guide post 307 of the guide member, realizing the relative movement between the hollow plate 1 and the connecting hollow plate 2. After adjusting to the required length, it is connected and fixed by the bolt in the fixing block 308 and the screw hole on the outer arc surface of the circular plate 305. When folding, rotate the bidirectional threaded rod 304 in the opposite direction to make the X-shaped connecting frame 301 move closer, and then the limit post 302 of the connecting hollow plate 2 is inserted into the connecting hole at the right end of the hollow plate 1 to support the whole unit.

[0037] Meanwhile, the support mechanism 4 provides layered support and clamping for the pipes: the height of the support plate 401, the placement plate 402, and the fixing plate 403 increases sequentially to form a layered placement space. The top of the support mechanism 401 and the semi-circular part of the pressure plate 405 are adapted to the shape of the pipes. The height of the pressure plate 405 can be adjusted by rotating the threaded rod 404 to clamp and fix pipes of different diameters, thus avoiding pipe accumulation. The two sets of support mechanisms 4 are fixed on the hollow plate 1 and the connecting hollow plate 2, respectively, to ensure that the pipes are placed stably during transportation.

[0038] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
