Abstract

A spline-type horizontal directional drilling engineering control device includes a casing. An adjustment component is provided on the inner wall of the casing. A first hole is opened at the middle position of the adjustment component, and a transmission pipe is provided on the inner wall of the first hole for collecting the collected soil. A guiding component is assembled at one end of the adjustment component for adjusting the angle of the exploration device inside the casing.

It can obtain a large amount of effective information with fewer drilling entry points and shorter drilling trajectories.

Description

Technical Field

[0001] The present invention relates to the technical field of engineering geological exploration, and particularly relates to a spline-type horizontal directional drilling engineering control device. Background Art

[0002] In geotechnical engineering geological exploration, the main means of engineering geological exploration include drilling, shaft exploration, trench exploration, adit exploration, aerial engineering geological survey and mapping, etc. Among them, geological drilling is the main method of geotechnical engineering exploration. For some large-depth and long-distance underground projects (such as tunnel projects, etc.). The traditional vertical-hole geological drilling device consists of a drill pipe and a core barrel. The drill pipe penetrates through the upper rock and soil mass to reach the tunnel axis position. The core barrel is used to drill the core at the core-taking point, and then the geological cross-section along the line is estimated by the connection method. Since this device can only obtain the cores at intervals along the tunnel axis, it cannot truly and comprehensively reflect the geological characteristics of the tunnel surrounding rock. Moreover, in special situations such as above sea level and densely built-up areas on the ground surface, the situation is complex, and it is relatively difficult to implement the exploration of geological conditions using vertical holes.

[0003] In addition, a Chinese patent application with the publication number CN114517652A discloses a spline-type horizontal directional drilling engineering geological exploration control device, including a housing, and also including an outer expansion structure. The outer expansion structure includes an inner frame and an auxiliary outer shell. The inner frame is connected to the housing, and the auxiliary outer shell is connected to the inner frame. An elastic support ring is connected to the housing. A storage groove is provided in the inner frame, and the storage groove is connected to a synchronous ring through a plurality of auxiliary return springs. The synchronous ring is connected to the elastic support ring. An annular groove communicating with a sealing cavity is provided in the inner frame, and a compression component is installed in the annular groove. A driving motor is installed in the auxiliary outer shell, and the output end of the driving motor drives the compression component through a synchronous component.

[0004] It can be seen that in the prior art, only the fixation during the drilling operation is realized. The contact surface between the elastic support ring and the inner wall of the drill hole is relatively large, so that the force is relatively uniform. At the same time, the damage to the inner wall of the drill hole during the fixation process and the release of the fixation process is relatively small, realizing the function of compaction and reinforcement of the inner wall of the drill hole. When the control device is in use, it is easy to directly hit the rock when encountering complex geology, and the drill bit will be damaged to a certain extent. At the same time, it is difficult to obtain the true underground information. The relocation of the equipment in complex terrain conditions has more drill entry points and a longer drilling trajectory, and the effective information obtained is limited.

[0005] In order to truly reflect the geological conditions along the underground line, and at the same time avoid the long-distance relocation of the equipment in complex terrain conditions, and be able to obtain a large amount of effective information with fewer drill entry points and a shorter drilling trajectory, there is an urgent need to provide a spline-type horizontal directional drilling engineering control device.

A ring 42 is installed at the mouth of the cover plate 33, and transmission teeth are provided on the ring 42. The transmission gear 24 meshes with the transmission teeth on the ring 42 to adjust and limit the guiding assembly 3. When it is necessary to adjust the angle of the drilling device 13, by rotating the transmission gear 24 to drive the ring 42 to rotate, the drilling device 13 and the cover plate 33 are moved, and the angle of one end of the drilling device 13 is adjusted, thereby adjusting the angle of drilling.

A third gear 41 is installed at the bottom end of the support block 39, and the third gear 41 meshes with the second gear 37 close to the cover plate 33. The drilling device 13 is installed on the support block 39. When the second gear 37 drives the third gear 41 to rotate, the support block 39 is driven to rotate, so as to drive the drilling device 13 to rotate.

[0034] In this embodiment, the drilling device 13 is composed of a support column, a connecting block and a helical gear block. The bottom end of the support column is fixedly connected to the top end of the support block 39, the top end of the support column is fixedly connected to the bottom end of the connecting block, and the helical gear is rotatably installed on the connecting block. When the entire guiding assembly 3 rotates during use, it drives a plurality of helical gear blocks to rotate around the sleeve 1.

[0035] In this embodiment, a through hole 34 is formed in the cover plate 33, and a first limiting plate 35 is installed on the through hole 34. Another through hole 34 opposite to the cover plate 33 is formed in the semi-cylinder at the upper part of the support frame 31. The two through holes 34 are arranged oppositely.

Further, the outer peripheral surfaces of the first limiting plate 35 and the second limiting plate 30 are respectively rotatably connected to the inner walls of the through holes 34, forming a double rotation structure. Specifically, the first rotation structure is the rotation of the outer peripheral surface of the limiting plate, and the second rotation structure is the rotation of the two ends of the connecting rod 36 within the limiting plate. This double rotation structure further ensures the smooth rotation of the connecting rod 36.

[0036] In this embodiment, the telescopic member 22 is composed of two straight cylinders and a round rod. The inner walls of the two straight cylinders are slidably connected to the outer surface of the round rod. At the same time, baffles are arranged at the ports of the two straight cylinders, and clamping blocks corresponding to the baffles are installed at both ends of the round rod.

[0037] In the present invention, the device is placed on the ground to be processed, and at the same time, the driving device is started, so that the entire drilling device 13 rotates and drills the ground. At the same time, when an obstacle is predicted to exist after a certain period of time, the transmission gear 24 can be rotated, so that the ring 42 connected to the transmission gear 24 rotates. Since the cover plate 33 is fixedly connected to the ring 42, the cover plate 33 is driven to rotate, so that the adjustment of the drilling device 13 is adjusted, and the first gear 25 rotates to drive the second gear 37 to rotate. Since the second gear 37 meshes with the third gear 41, the third gear 41 rotates. At the same time, the third gear 41 drives the support block 39 to rotate, so that the angle of the drilling device 13 is adjusted.
