Description

Technical Field

[0001] The utility model belongs to the technical field of tunnel construction protection, and particularly relates to a drilling deviation correction device applied to the construction of extra-long pipe roofs. Background Technique

[0002] In recent years, the pipe roof support technology has developed rapidly and is widely used in the construction of subway shield tunnels for supporting and reinforcing the stratum. The pipe roof support technology has the advantages of long advanced support distance and large stiffness, and can better be applied to the situation where the drilling working face cannot be self-stabilized and the water-bearing stratum. The pipe roof and the tunnel structure jointly form a support system, which can effectively control the deformation of the surrounding rock. When constructing the pipe roof, it is necessary to use the drill pipe of the pipe roof drilling rig to drill holes first.

[0003] During the construction of the existing extra-long pipe roof, a pipe roof drilling rig is used to drill holes with a drill pipe first. During this process, due to the extremely long length of the construction pipe roof, as the drill pipe continuously drills, there will be a phenomenon of guiding deviation, which is detected by an inclinometer, and then the drill pipe is corrected for deviation. In actual use, because the pipe roof drilling rig carries the drill pipe, after the guiding deviation of the drill pipe is detected by the inclinometer, it is necessary to correct the drill pipe for deviation as soon as possible to ensure the construction accuracy.

[0004] At present, the invention patent with the publication number of CN117386308 A discloses a guiding and deviation correction device applied to the construction of extra-long pipe roofs. By fixedly arranging a pre-inserted pipe roof sleeve and a guiding and deviation correction mechanism at the tunnel entrance, the user remotely controls the first deviation correction component and the second deviation correction component in the guiding and deviation correction mechanism, and uses a vertical hydraulic cylinder to adjust up and down and a horizontal hydraulic cylinder to adjust left and right, so as to adjust the drilling direction of the drill pipe and achieve the purpose of deviation correction. However, the following problems still exist in the use of this deviation correction device:

[0005] The pre-inserted pipe roof sleeve is fixedly arranged at the tunnel entrance, and the guiding and deviation correction mechanism is arranged on the pre-inserted pipe roof sleeve. When correcting the deviation, taking the pre-inserted pipe roof sleeve as the fulcrum and the guiding and deviation correction mechanism as the adjustment structure to correct the deviation of the drill pipe of the pipe roof drilling rig. However, when the drill pipe extends too long into the tunnel, the adjustment effect is not good when adjusting the drill pipe at the tunnel entrance. After being detected by the inclinometer, if the pipe roof drilling rig carries the drill pipe to adjust the angle back and forth, it is inconvenient to operate, and the drilling direction cannot be corrected in time, affecting the work efficiency.

[0006] Therefore, it is urgent to design a drilling deviation correction device applied to the construction of extra-long pipe roofs to solve the above problems, simply and quickly adjust the drilling direction, and improve the work efficiency. Content of the Utility Model

[0007] In view of the problems existing in the above-mentioned prior art, such as poor adjustment effect on drill pipes, cumbersome operation and inability to correct the drilling direction in time, which in turn affect the work efficiency, the present utility model provides a drilling deviation correction device applied to the construction of extra-long pipe roofs, including two drill pipe sleeves, a plurality of deviation correction components and a plurality of guiding and monitoring components. Through the mutual cooperation of these multiple technical features, timely deviation correction is achieved for the angle deviation and position deviation of the drill pipe during the drilling process, ensuring that the drilling angle and position of the drill pipe meet the requirements.

[0008] The core technical idea of the present utility model is as follows: The guiding and monitoring components monitor the deviation of the drill pipe in terms of angle and position during the drilling process in real time. Once deviation is detected, the deviation correction components are activated, which cooperate with the rock wall to timely correct the working drill pipe, and at the same time, the guiding and monitoring components detect the deviation correction result.

[0036] Embodiment:

[0037] Referring to Figure 1-7 A drilling deviation rectification device applied to the construction of ultra-long pipe roofs as shown. The deviation rectification device includes a plurality of drill pipe sleeves 3, a plurality of deviation rectification assemblies 4, and a plurality of guiding and monitoring assemblies 5. Two drill pipe sleeves 3 are sleeved on the pipe roof drill pipe 2; a plurality of deviation rectification assemblies 4 are arranged between the two drill pipe sleeves 3 and are slidably connected to the drill pipe sleeves 3, and a plurality of guiding and monitoring assemblies 5 are arranged on the outer surface of the drill pipe sleeves 3; wherein, preferably, there are two drill pipe sleeves 3, four deviation rectification assemblies 4, and a drill bit 1 is installed at the end of the pipe roof drill pipe 2, as shown in the attached Figure 6 figure.

[0038] The guiding and monitoring assembly 5 monitors the angle and position deviation of the drill pipe 2 during operation in real time. The deviation rectification assembly 4 is slidably arranged between the two drill pipe sleeves 3 and rectifies the pipe roof drill pipe 2 according to the data monitored by the guiding and monitoring assembly 5, so that the pipe roof drill pipe 2 works according to the moving angle and position.

[0039] Specifically, referring to the attached Figure 2 and Figure 5 figures, the drill pipe sleeve 3 includes a mutually sleeved pipe sleeve 301 and a bearing 302, and the bearing 302 is arranged on the pipe roof drill pipe 2 through a rubber ring sleeve 302-1. The purpose of the rubber ring is to reinforce the stability of the connection between the pipe roof drill pipe 2 and the bearing 302.

[0040] Specifically, referring to the attached Figure 3 figure, the deviation rectification assembly 4 includes a sliding block 401, an adjusting rod assembly 402, and a telescopic member 403. The adjusting rod assembly 402 is arranged between the two drill pipe sleeves 3 through the sliding block 401. The sliding block 401 is used in cooperation with a chute 301-1 opened on the outer side surface of the pipe sleeve 301. At the same time, the adjusting rod assembly 402 is hinged to the sliding block 401. The telescopic member 403 is arranged between the two drill pipe sleeves 3 and is connected to the sliding block 401. Preferably, the telescopic member 403 is a hydraulic cylinder.

[0041] Further, the adjusting rod assembly 402 includes two adjusting rods 402-1 and a top block 402-2. The ends of the two adjusting rods 402-1 are hinged by the top block 402-2, and the other ends are hinged to the sliding block 401. The angle between the two adjusting rods 402-1 is adjustable, and the adjusting rod 402-1 can rotate relative to the sliding block 401.

[0042] Specifically, refer to the attached Figure 4 As shown, the guiding and monitoring assembly 5 includes a fixed block 501 and an infrared laser 502. Preferably, the fixed block 501 has a triangular structure, and the fixed block 501 is respectively arranged on the outer end faces of the two drill pipe sleeves 3. The infrared lasers 502 are respectively arranged on two faces of the fixed block 501, and the angle between the two faces is 90°. One of the lights emitted by the two infrared lasers 502 is in the horizontal direction, and the other is in the vertical direction. By the distance feedback of the vertical and horizontal infrared lasers, it is judged whether it meets the preset distance range, so as to judge whether the angle of the pipe shed drilling direction is deviated and measure the deviation distance.

[0043] Specific process of judging the elevation angle deviation: Here, the infrared lasers 502 on the drill pipe sleeve 3 close to the drill bit 1 are needed. There are two, which are respectively arranged at the upper and lower ends of the drill pipe sleeve 3. The two infrared lasers 502 respectively emit infrared lasers in the vertical and horizontal directions. Assume that the elevation angle of the drill pipe sleeve 3 (i.e., the drill pipe 2) needs to be 15° before drilling. Then, using the principle of similar triangles of a right triangle, at a fixed angle, the two right sides are proportional, and the expected feedback distances of the vertical and horizontal infrared lasers can be calculated. When the elevation angle remains unchanged, the feedback distances of the vertical and horizontal infrared lasers are fixed. Therefore, during drilling, the laser emitted by the infrared laser 502 hits the rock mass and feeds back to the laser instrument, and then the feedback distances of the vertical and horizontal lasers are measured. According to the feedback distances of the vertical and horizontal lasers, it can be judged whether the elevation angle of the drill pipe sleeve 3 meets the requirements. If not, immediate correction is required, as Figure 7 shown;

[0044] Specific process of judging the position deviation: Here, the infrared lasers 502 on the drill pipe sleeve 3 far from the drill bit 1 are needed. There are two, which are respectively arranged at the upper and lower ends of the drill pipe sleeve 3. By the feedback distances of the vertical and horizontal lasers emitted by the two infrared lasers 502, it is further obtained whether the drill pipe sleeve 3 meets its position requirements in the tunnel. If not, immediate correction is required;

[0045] The principle and process of the drilling deviation correction device applied to the construction of ultra-long pipe roofs in actual use are as follows: After detecting the elevation angle deviation during drilling, the telescopic member 403 is activated, and the relative positions of the two sliding blocks 401 are adjusted by using the telescopic member 403, so as to adjust the included angle between the two adjusting rods 402-1, and then the distance between the top block 402-2 and the inner wall of the surrounding rock is adjusted. The deviation angle of the drill pipe 2 is adjusted by using the reaction force of the inner wall of the surrounding rock.

[0046] Specifically, the telescopic member 403 in the deviation direction is opened, so that the distance between the connected sliding blocks 401 is reduced, the included angle between the two adjusting rods 402-1 is reduced, and then the top block 402-2 is jacked up to contact the inner wall of the surrounding rock, and the deviation angle is adjusted by using the reaction force of the inner wall of the surrounding rock. At the same time, the distance between the two sliders connected to the other telescopic member 403 directly below the telescopic member 403 is increased, the included angle between the two adjusting rods 402-1 is increased, and the top block 402-2 is away from the inner wall of the surrounding rock. Through the mutual cooperation between the two telescopic members 403, the deviation correction of the drill pipe 2 is realized. The deviation correction of the drill pipe 2 in terms of position deviation is the same as the above principle and will not be elaborated here.

[0047] The above shows and describes the basic principle, main features and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited by the above embodiments. What is described in the above embodiments and the specification only illustrates the principle of the present invention.
