Technical Field

[0002] Coal mine TBM construction measurement is a construction measurement method used in coal mine engineering. TBM is an engineering equipment used to dig tunnels. It has the characteristics of high speed, high precision and high efficiency. In coal mine engineering, TBM construction measurement is mainly used in tunnel excavation, tunnel support, geological exploration and other aspects. Coal mine TBM construction measurement is an important link in coal mine engineering and is of great significance to ensuring the quality, safety and progress of the project.

[0003] During the measurement process, it is necessary to use instruments such as total stations to measure construction data. Due to the complex environment of coal mines, there are a lot of foreign matter such as water vapor and dust inside the coal mine tunnels. Foreign matter is easy to adhere to the total station and other components. When used for a long time, foreign matter will block the detection signal of the detection instrument, making the detection data inaccurate, and on the other hand, it can also cause corrosion damage to the instrument. The detection instrument is inconvenient to operate during installation and is not suitable for installation and detection operations at different locations.

[0059] Working principle:

[0060] The total station used for construction measurement is installed on the top of the total station installation mechanism 5 in the cover shell 2, and the total station installation mechanism 5 is rotated according to the detection orientation to adjust the detection direction of the total station, and then the total station installation mechanism 5 is locked and fixed by the locking mechanism 6, and the power cable and signal cable used for detection are led out of the cover shell 2 from the lead mechanism 7. Thereafter, the installation method of the measuring platform is determined according to the detection position of the coal mine tunnel, and the tunnel bottom, tunnel side wall and tunnel top are selected for hoisting and installation according to the detection needs; the angle between the extension rod 44 and the column 42 is adjusted by the steering mechanism 43 on the installation component 4, so as to realize the adjustable installation under different conditions, and then the position of the movable rod 45 and the extension rod 44 is adjusted, and the pad 46 is fixed to the tunnel with screws, and finally the stabilizing mechanism is used to install the adjacent installation components 4 in a group to complete the stabilization of the installation component 4;

[0061] When performing installation adjustment, first pull the push-pull rod 24 to make the limiting rod 25 extend out of the limiting groove 23, and the limiting rod 25 does not limit the limiting groove 23 and the rotating rod 22, and then deflect the extension rod 44 to adjust the position between the extension rod 44 and the column 42, and select the installation method of hoisting at the bottom of the tunnel, the side wall of the tunnel, and the top of the tunnel according to the position between the extension rod 44 and the column 42;

[0062] When the stabilizing component is connected to the mounting component 4, the clamping plate 99 on the stabilizing component is first rotated to make the clamping plate 99 not interfere with the adjusting rod 91, so that the pull rod 95 can slide along its length direction, and the pull rod 95 is pulled to move away from the clamping plate 99, so that the contact plate 97 on the cross plate 96 is not engaged with the interference groove 98 on the sleeve 92, and then the pull rod 95 is pushed to make the adjusting rod 91 rotate along its axis. When the adjusting rod 91 rotates, the tension rod 93 slides along its length direction under the action of the thread. In order to facilitate the two sets of tension rods 93 to move in opposite directions during movement, The two ends of the adjusting rod 91 are provided with threaded holes which are symmetrically arranged along the middle thereof and threadedly sleeved with the tensioning rod 93, so as to adjust the distance between the two sets of locking plates 94. During installation, the locking plates 94 are extended into the concave position of the lap plate 82 along the entrance 83 on the lap plate 82, and then the stabilizing assembly is rotated 90 degrees to make the locking plates 94 rotate 90 degrees for easy docking with the lap plate 82.

At this time, the locking and engagement between the sliding block 81 and the guide plate 31 and between the locking plate 94 and the lap plate 82 are completed in the tightened state; and in the locked state, the centers of the locking plate 94 and the lap plate 82 are both located on the axis of the extension rod 44; the overlapping and locking operation of the stabilizing components between the three groups of installation components 4 is completed in the above manner, and at this time, the three groups of stabilizing components form a triangular structure on the three groups of installation components 4, and the triangular structure formed by the three groups of stabilizing components is located on the same plane, thereby ensuring that the reinforcement between the installation components 4 is firm and reliable;

[0064] When adjusting the detection direction of the total station, the turntable 51 is pushed to rotate and fine-tune the position of the total station set on the top of the placement plate 52. Thereafter, the driving rod 63 is rotated to drive the movable plate 62 to move along its length direction, so that the clamping plate 61 is engaged with the positioning plate 53, thereby limiting the rotation of the turntable 51.

[0065] When the cable is released, the cable is passed through the housing 2 between the two sets of release plates 75, and the adjusting screw 71 is rotated to make the two sets of push rods 73 mobilize the closing plate 74 to move, and then the release plates 75 move towards each other, so that the cable is stored between the two sets of release plates 75, and at the same time, the sealing plate clamps the cable and closes it from the bottom of the closed release plates 75;

[0066] When using the total station for detection, start the motor, then the bearing ring rotates under the action of the gear and the gear ring, and then the rotating cleaning brush cleans the dust and foreign matter on the outer wall of the cover 2, thereby reducing the obstruction of the total station signal by dust and foreign matter;

[0067] The design realizes the closed installation of the total station, which is installed in a closed environment, reduces the interference and pollution of water vapor, dust and foreign matter in the coal mine tunnels on the total station body, improves the total station detection environment, and reduces the loss of the total station; it realizes installation and operation in different conditions in coal mine tunnels, which is convenient for detection at different positions. The installation connection is stable, which is convenient for measurement personnel to perform installation operations, reduces the difficulty of installation operations for measurement personnel, and improves detection efficiency; it can remove the dust deposited outside the cover to avoid dust interference and blocking the total station signal transmission, does not require manual cleaning, improves detection accuracy and duration, reduces the maintenance difficulty and maintenance cost of detection personnel, and facilitates the lead-out of cables.
