Description

Technical Field

[0001] The utility model relates to an automatic control device for the construction posture of a tunnel TBM equipment. Background Art

[0002] TBM equipment uses the PPS measurement system installed on the equipment for guidance. During the construction process, manual calibration with theodolite or total station is required to ensure the correct posture of the TBM equipment and to operate according to the designed axis. Its disadvantages are: 1. During the excavation process, the data in the PPS measurement system computer fluctuates greatly due to adverse working environment conditions such as dust, and the correct direction cannot be determined, thus affecting the construction; 2. The measuring stations and backsight points installed on the tunnel wall sometimes become loose or displaced, causing the measurement system deviation to be unable to be displayed in time on the control computer, causing the excavation direction to deviate from the designed axis direction.

DETAILED DESCRIPTION

[0017] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0018] like Figure 1 and 2 As shown, a tunnel TBM equipment construction posture automatic control device includes a cutter head 1, which is connected to a TBM host 4 through multiple oil cylinders 2, and an oil tank 5 and a TBM posture control unit 3 are installed on the TBM host 4. Multiple oil pumps 6 are installed on the oil tank 5, and each oil pump 6 is connected to each oil cylinder 2 through a hydraulic oil pipe. The TBM posture control unit 3 includes an electronic gyroscope 9, an equipment positioning module 10, a data calculation and comparison module 8, and a pressure adjustment module 7 connected in sequence, and the pressure adjustment module 7 is connected to each oil pump 6. The direction of the cutter head 1 is adjusted by controlling the extension and contraction of each oil cylinder 2.

[0019] It also includes a wireless communication module connected to the data calculation and comparison module 8, and the data calculation and comparison module 8 is connected to the user through the wireless communication module. The wireless communication module is a wifi module or a bluetooth module, which is used to send the coordinates to the user in real time for monitoring.

[0020] The coordinate input device 11 is also included, and the coordinate input device 11 is connected to the data calculation and comparison module 8 via an optical fiber or a network cable. The coordinate input device 11 is used to manually correct the coordinates of the cutter head 1.

[0021] The working process of the utility model is as follows: first, the initial state of the electronic gyroscope 9 is manually calibrated using a theodolite to make it at the initial position of the design axis, ensuring that the coordinates transmitted to the TBM attitude control unit 3 through the equipment positioning module 10 are consistent with the design coordinates imported through the coordinate input device 11; then, during the construction of the TBM equipment, the working coordinates measured in real time by the electronic gyroscope 9 and the equipment positioning module 10 in the TBM attitude control unit 3 are returned to the data calculation and comparison module 8, and the data calculation and comparison module 8 is used to compare the measured working coordinates with the design coordinates imported from the coordinate input device 11. When the comparison result exceeds the preset error range, the TBM attitude control unit 3 transmits a construction suspension signal to the main control circuit, and at the same time transmits the comparison result to the pressure adjustment module 7 to start the oil pump 6 to push the oil cylinder 2 to work, and adjust the attitude of the TBM equipment cutter head 1. The above process is repeated again until the comparison result is within the preset error range, and the TBM equipment automatically continues the construction, thereby achieving the purpose of automatically adjusting the attitude of the TBM equipment during work.
