Description

Technical Field

[0001] The present invention relates to the technical field related to horizontal directional drilling construction, and specifically, it is a non-excavation horizontal directional drilling construction device. Background Art

[0002] After a horizontal directional drilling rig drills a hole on the ground, pipelines are usually laid. Usually, after blocking the front end of the pipeline to be laid, a pipe pulling head with a strength greater than that of the pipeline to be laid is set, and the pipe pulling head is welded to the front end of the pipeline to be laid. The pipe pulling head is pulled by a steel wire rope, and then the pipeline is laid in the hole drilled by the horizontal directional drilling rig. After the pipeline laying is completed, the pipe pulling head is cut off.

[0003] When laying pipelines in this way, the loss of pipe materials is large, and the residual gravel or rough sections on the inner wall of the hole will damage the outer wall of the pipeline and hinder the smooth movement of the pipeline in the hole. Therefore, a non-excavation horizontal directional drilling construction device is proposed. Summary of the Invention

[0004] The purpose of the present invention is to provide a non-excavation horizontal directional drilling construction device to solve the problems raised in the above background art.

[0005] To achieve the above purpose, the present invention provides the following technical solutions:

One end of the pull rod is connected with a pull ring, and the other end of the pull rod is connected with a socket assembly. The socket assembly can be cooperatively connected with the port part of the pipeline body. A driving assembly and a cleaning assembly are arranged in the middle of the pull rod. The driving assembly is fixedly and cooperatively connected with the pull rod, and the cleaning assembly is rotationally cooperatively connected with the pull rod. The driving assembly is arranged inside the cleaning assembly and is cooperatively connected with the cleaning assembly. The driving assembly is used to drive the cleaning assembly to rotate around the central axis of the pull rod.

The inner wall of the inner cylinder is connected with a first rotating sleeve through a plurality of first connecting rods. The first rotating sleeve is rotationally and cooperatively connected with the pull rod.

[0009] As a further solution of the present invention: The driving component includes a mounting sleeve installed on the pull rod, a driving member arranged inside the mounting sleeve, and a protection frame arranged on the pull rod and located outside the driving member. The output end of the driving member is connected with a driving gear. A driven gear ring is connected to the outer wall of the first rotating sleeve. The driving gear is meshed and connected with the driven gear ring.

[0010] As a further solution of the present invention: The flattening component includes a mounting frame arranged on the pull rod, a second connecting plate connected to the periphery of the mounting frame, and a flattening frame connected to the periphery of the second connecting plate. There is a gap between the second connecting plate and the first connecting plate.

[0011] As a further solution of the present invention: A through hole is arranged in the middle of the first connecting plate. A conveying component is jointly arranged in the through hole and inside the mounting frame. The conveying component includes a second rotating sleeve and an arc-shaped conveying plate. The second rotating sleeve is rotationally and cooperatively connected with the pull rod. The outer wall of the second rotating sleeve is connected to the inner side wall of the arc-shaped conveying plate through a second connecting rod.

[0012] As a further solution of the present invention: The moving component includes a bearing sleeve arranged in cooperation with the pull rod and a plurality of wheel frames symmetrically connected to the periphery of the bearing sleeve through support rods. Moving wheels are arranged on the wheel frames.

[0013] Compared with the prior art, the beneficial effects of the present invention are as follows: While the device uses two moving components to assist the movement of the pull rod, it improves the movement stability of the cleaning component and the flattening component. The moving component is provided with multiple moving wheels that can adjust their positions by themselves, and has a good moving obstacle avoidance effect.

[0029] Working principle: When the device is in use, the inner envelope 302 is inserted into the port of the pipeline body 9. The outer clamping plate 303 is installed on the mounting plate 301 through bolts 304. The end of the pipeline body 9 is clamped and fixed by the outer clamping plate 303 and the inner envelope 302. The traction of the pull rod 1 is realized by threading the steel wire rope through the pull ring 2. Then, the pipeline body 9 is pulled into the hole for laying. The moving assembly 4 is used to assist the pull rod 1 to move smoothly in the drill hole. The driving member 603 is driven to drive the driving gear 604 to rotate. Then, the driven gear ring 509 drives the first connecting rod 511 to rotate. Then, the inner cylinder 502 and the outer cylinder 503 are driven to rotate. Then, the annular scraping knife 504 is driven to rotate to clean the gravel, soil clumps and other impurities on the inner wall of the drill hole. Part of the gravel and impurities cleaned are introduced into the accommodation cavity 507 through the first inclined surface 505. As the inner cylinder 502 and the outer cylinder 503 rotate, the gravel and impurities in the accommodation cavity 507 fall down along the trend and are discharged from the bottom port of the accommodation cavity 507. Then, as the pull rod 1 moves, the flattening frame 703 at the rear moves forward to press the gravel and impurities onto the bottom surface of the hole. Another part of the gravel and impurities fall between the first connecting plate 501 and the second connecting plate 702 through the second inclined surface 506, then fall onto the arc-shaped conveying plate 803, and then are discharged into the inner part of the inner cylinder 502. Then, the gravel and impurities are discharged forward and downward along the inner wall of the inner cylinder 502, and then are flattened and tamped by the flattening frame 703. When the axial position of the pull rod 1 changes, the use functions of the driving assembly 6 and the cleaning assembly 5 are not affected. The arc-shaped conveying plate 803 is always in a hanging state and its conveying function is not affected.

[0030] The above describes the preferred embodiments of this patent in detail. However, this patent is not limited to the above embodiments. Within the scope of knowledge possessed by those of ordinary skill in the art, various changes can be made without departing from the purpose of this patent.
