[0001] The present application relates to the technical field of tunnel detection, and in particular to a drilling rig drilling detection system and a detection method thereof. Background Art

[0002] A drilling rig, also known as a drilling rig, is a type of rock drilling equipment used in tunnel and underground projects using the drill and blast method. The drilling rig can move and support multiple rock drills to perform drilling operations simultaneously. Before tunnel excavation, it is necessary to measure and map the excavated tunnel section in order to locate the reasonable blasthole points. The drilling rig then performs operations such as drilling and cleaning the blasthole points. After the holes are cleaned, explosives and water bags need to be placed in each blasthole in turn, and finally the blastholes are sealed with gun mud. After the explosives are installed, the explosives are connected with fuses, and all the fuses are connected together for easy one-time ignition and detonation, and finally the section of the tunnel that needs to be excavated is blasted.

[0003] After blasting a section of rock mass, the existing rock drilling rig needs to place a scanner on the ground in the tunnel after the blasting to detect the tunnel section after the blasting to verify the blasting effect, and use this as a basis to adjust various blasting parameters for the next blasting.

[0004] During inspection, the scanner needs to be placed manually in the excavated tunnel, but a tunnel that has just been blasted is usually unstable, with a lot of dust inside and even falling gravel.

[0029] A placement platform 2 is fixed on the top of the driving position of the drilling trolley body 1. The placement platform 2 is placed horizontally, and a protective cover 21 is placed on the top of the placement platform 2. The protective cover 21 has an opening on one side facing the forward direction of the drilling trolley body 1.

[0030] The top surface of the placement platform 2 is rotatably connected to a turntable 22, the protective cover 21 is fixed to the top surface of the turntable 22, the rotation axis of the turntable 22 is vertical, and a connecting shaft 221 is coaxially fixed to the bottom of the turntable 22, and a driven gear 222 is coaxially fixed to the outer surface of the connecting shaft 221, and a first driving member 23 and a driving gear 24 are also provided inside the placement platform 2, wherein the driving gear 24 is meshed with the driven gear 222, and the driving gear 24 and the driven gear 222 are a pair of bevel gears meshing with each other. The first driving member 23 can be a small servo motor, and the output shaft of the first driving member 23 is coaxially fixed with the driving gear 24, which is used to drive the driving gear 24 to rotate. The first driving member 23 can drive the turntable 22 to rotate through the mutually meshing driving gear 24 and the driven gear 222.

[0031] Reference Figure 2 and Figure 3A laser scanner 3 is placed in the protective cover 21. The laser scanner 3 can be a three-dimensional laser scanner 3. The laser scanner 3 can scan and detect the cross section of the tunnel rock wall after blasting. A control unit and a data processing module (not shown) are also provided in the drilling trolley body 1. The drill arm 11 is electrically connected to the control unit. The control unit can directly control the operation of the drill arm 11. The laser scanner 3 is electrically connected to the data processing module. The data obtained after scanning by the laser scanner 3 can be transmitted to the data processing module for analysis. The laser scanner 3 is placed on the turntable 22 and can rotate with the turntable 22, so as to facilitate the adjustment of the detection direction. The control unit can be electrically connected to the first driving member 23, so that the operation of the first driving member 23 can be directly and automatically controlled by the control unit.

[0032] After the drill arm 11 has completed drilling and blasting the tunnel rock wall, the construction personnel can drive a drilling trolley into the tunnel for inspection. The drilling trolley is equipped with a laser scanner 3, which scans and inspects the tunnel rock wall section and transmits the scanned data to the data processing module for analysis. The control unit adjusts the subsequent drilling parameters and sends an action instruction to the drill arm 11 again, so as to adjust the next drilling operation in time. After entering the tunnel, the construction personnel are protected by the drilling trolley to ensure their personal safety and reduce the risk of injury to the construction personnel.

[0033] Reference Figure 3 and Figure 4 A guide rail 4 is fixed on the top surface of the placement platform 2 corresponding to the position of the protective cover 21. Two guide rails 4 are provided, which are parallel to each other and spaced apart. A supporting slider 41 is slidably connected to each guide rail 4. The supporting slider 41 is used to support the laser scanner 3. A positioning groove 5 is formed between the two supporting sliders 41. The positioning groove 5 makes way for the bracket connection seat at the bottom of the laser scanner 3, and at the same time facilitates the positioning and insertion of the bracket connection seat at the bottom of the laser scanner 3. One end of the guide rail 4 extends outward from the opening of the protective cover 21. When the laser scanner 3 is placed on the supporting slider 41, an external force can be applied to push the laser scanner 3 into the protective cover 21.

[0034] In order to further improve the operational stability of the laser scanner 3, a first buffer block 42 is vertically slidably connected in the supporting slider 41. The upper surface of the first buffer block 42 exceeds the upper surface of the supporting slider 41 and abuts against the bottom of the laser scanner 3. A first elastic member 43 is also provided in the supporting slider 41. The first elastic member 43 may be a compression spring and multiple first elastic members 43 are provided. The first elastic members 43 are all placed vertically, one end of the first elastic member 43 abuts against the bottom of the first buffer block 42, and the other end abuts against the inner bottom wall of the supporting slider 41. If the drilling trolley vibrates when running or stationary, the first buffer block 42 may slide relative to the supporting slider 41. During this process, the first elastic member 43 will be compressed by the first buffer block 42 and oscillate, which can effectively absorb the vibration from the drilling trolley, making the measurement process of the laser scanner 3 more stable and the data obtained by the measurement more accurate.

[0035] In order to further limit the displacement of the laser scanner 3, a clamping assembly 6 is also provided in the protective cover 21. The clamping assembly 6 includes a double-headed screw 61 and two clamping plates 62. The double-headed screw 61 is placed horizontally and both ends are rotatably connected to the protective cover 21. The two clamping plates 62 are respectively located on both sides of the laser scanner 3 and are parallel to each other. The double-headed screw 61 is simultaneously penetrated and threadedly connected with the two clamping plates 62. The double-headed screw 61 includes two threaded sections with opposite rotation directions. The two clamping plates 62 are respectively located on different threaded sections of the double-headed screw 61. A second driving member 211 for driving the double-headed screw 61 to rotate is fixed to the outer wall of the protective cover 21 corresponding to the double-headed screw 61. The second driving member 211 can be a small servo motor. The output shaft of the second driving member 211 is coaxially fixed with the double-headed screw 61.

[0036] When the double-ended screw 61 rotates, the two clamping plates 62 can move toward or away from each other, thereby achieving a clamping or releasing action, and then the laser scanner 3 can be clamped or released. The control unit can automatically control the clamping or releasing action of the clamping plate 62 by controlling the operation of the second driving member 211. In order to further improve the stability of the clamping plate 62 during operation, a guide rod 63 can be provided below the double-ended screw 61. The guide rod 63 can be a square rod. The guide rod 63 is penetrated through the two clamping plates 62 and is slidably connected to the two clamping plates 62. The guide rod 63 can provide a stable guide for the sliding of the clamping plate 62.

[0037] Reference Figure 4 and Figure 5, second buffer blocks 621 are arranged on the inner side walls opposite to each other of the two clamping plates 62, the second buffer blocks 621 are horizontally slidably connected to the clamping plates 62, the side walls of the second buffer blocks 621 can abut against the side walls of the laser scanner 3, and a second elastic member 622 is arranged between the second buffer blocks 621 and the clamping plates 62, one end of the second elastic member 622 is connected to the inner side wall of the second buffer block 621, and the other end is connected to the inner side wall of the clamping plates 62. If the drilling trolley vibrates when running or stationary, the second buffer block 621 can slide relative to the clamping plates 62, and in this process, the second elastic member 622 will be compressed by the second buffer block 621 and vibrate, so that the second elastic member 622 can also absorb the vibration from the drilling trolley, further improving the working stability of the laser scanner 3.

[0038] Reference Figure 2 and Figure 4 In order to clean the inside of the protective cover 21, a fixing plate 7 is fixed to the back of the protective cover 21 away from the opening. A plurality of parallel shunt pipes 71 are inserted into the fixing plate 7. The number of shunt pipes 71 can be set according to the size of the actual fixing plate 7. All shunt pipes 71 are connected to an air duct 72 at one end away from the protective cover 21. The air duct 72 passes through the fixing plate 7 and can be connected to an external air source such as an air compressor. The end of the shunt pipe 71 away from the air duct 72 is inserted into the side wall of the protective cover 21 and is connected to the internal space of the protective cover 21. The air outlets of the shunt pipes 71 are all facing the opening direction of the protective cover 21.

[0039] After the air duct 72 is connected to the external wind source, the external airflow can enter the branch pipes 71 through the air duct 72, and finally enter the internal space of the protective cover 21 from the air outlet of each branch pipe 71. When there is a lot of dust accumulation in the protective cover 21, the laser scanner 3 can be taken out first, and then the external airflow can be used to blow the internal space of the protective cover 21, so as to clean the dust accumulated in the protective cover 21.

[0040] The implementation principle of a drilling detection system for a drilling rig in Example 1 of the present application is as follows: a laser scanner 3 is installed on the drilling rig. After the tunnel blasting is completed, the laser scanner 3 can directly scan and measure the tunnel section, and transmit the scanned data to the data processing module for analysis. The control unit adjusts the subsequent drilling parameters and sends an action instruction to the re-drilling arm 11, so as to adjust the next drilling operation in time. The laser scanner 3 is placed on a sliding supporting slider 41, so that the construction personnel can more conveniently take out or put in the laser scanner 3. The clamping assembly 6 is used to clamp and fix the laser scanner 3, which effectively improves the placement stability of the laser scanner 3.

[0041] Embodiment 2: Embodiment 2 of the present application discloses a drilling rig borehole detection method, which uses the drilling rig borehole detection system described in Embodiment 1 to detect the tunnel section after blasting, and specifically includes the following steps: S1: Scanning the tunnel section after blasting by laser scanner 3 to obtain point cloud data of the tunnel; then transmitting the point cloud data to the data processing module for preprocessing to obtain preprocessed data, including using the three-dimensional laser scanner 3 to continuously scan the tunnel section by using a positioning target ball; S2: Perform registration, denoising, coordinate system normalization, compression and 3D reconstruction on the acquired point cloud data, and import the acquired data into the computing software. S3: Through the tunnel design section, calculate the distance and direction from the characteristic point of the design section to the measured section line, and automatically detect over-break and under-break. After the data preprocessing is completed, perform point cloud analysis and display the over-break and under-break data of the current mileage in real time. The data processing module recalculates the parameters that the drill arm 11 needs to adjust for the next excavation. The control unit re-gives various drilling parameters according to the data processing module and resends action instructions to the drill arm 11 for the next drilling operation.
