Description

Technical Field

[0001] The present invention relates to the field of tunnel detection, and specifically to an intelligent tunnel cross-section detection trolley and a usage method thereof. Background Technique

[0002] The clear span cross-section size of the secondary lining of a tunnel is an important parameter for tunnel detection. If the tunnel clear span does not meet the design requirements, it will be a one-vote veto and the tunnel cannot pass the acceptance. The detection of the primary support cross-section is also very important. This work determines the thickness of the secondary lining of the tunnel. If the detection is unqualified, it should be adjusted in time to ensure that the thickness of the secondary lining of the tunnel meets the design and specification requirements. The thickness of the secondary lining will directly affect the overall stress of the tunnel and form a safety hazard. At the same time, for the freshly excavated cross-section, through cross-section detection, the over-excavation and under-excavation conditions can be grasped in time, and over-excavation and under-excavation treatment control can be carried out. At present, when detecting the tunnel cross-section, a cross-section instrument is generally used for detection. However, before the detection, it is necessary to use a total station to release the cross-section center line and side lines through known control points, which is relatively complicated, has low efficiency, and requires the cooperation of multiple workers, running counter to the current advocated green and intelligent detection.

[0003] The present invention utilizes a tunnel multi-functional cross-section detection trolley and a usage method thereof, and designs a tunnel multi-functional cross-section detection trolley and a usage method thereof from the perspectives of convenience, practicality, innovation, applicability, high efficiency, accuracy, improving the engineering detection efficiency, and ensuring the construction progress. Through practice, it is proved that this device is convenient to use, practical, accurate, applicable, and universal. It can not only detect the sizes of cross-sections (excavation surface, primary support, secondary lining) efficiently and quickly, reduce the construction cost, but also be applicable to the detection of different lining structure cross-sections. In summary, it improves the adaptability, detection quality and efficiency, saves the construction cost, realizes the concept of mechanization and reduction of personnel, and practices green detection. Summary of the Invention

[0004] The purpose of the present invention is to provide an intelligent tunnel cross-section detection trolley and a usage method thereof to solve the problems raised in the above background technique.

[0005] To achieve the above purpose, the present invention provides the following technical solution: An intelligent tunnel cross-section detection trolley includes a first slide rail and a second slide rail. The first slide rail is located above the second slide rail and is slidably arranged relative to the second slide rail. The first slide rail is concentric with the inner clear span cross-section of the tunnel secondary lining. A cross-slope regulator is arranged at the center of the circle. The regulator is relatively fixed to the first slide rail. Distance measuring instruments are arranged at both ends of the first slide rail, and the distance measuring instruments can move along the first slide rail. The second slide rail is installed on a base arranged below it, and a rotation module, a lifting module, and a horizontal movement module are arranged on the base.

[0006] Preferably, a sliding member is slidably installed on the first slide rail. The sliding member is driven by a first motor to move along the first slide rail, and the distance measuring instrument is fixedly installed outside the sliding member.

[0007] Preferably, the distance measuring instrument is a laser distance measuring instrument.

[0008] Preferably, a slider is fixed to the bottom of the first slide rail. The slider is slidably mounted on the second slide rail and is driven by a second motor. The regulator is fixedly mounted on the slider.

[0009] Preferably, the base includes a turntable. The rotating surface of the turntable is fixed to the bottom of the second slide rail. A plurality of self-driven rollers and a plurality of lifting legs are mounted at the bottom of the turntable. The turntable is driven by a third motor, the rollers are driven by a second motor, and the lifting legs are hydraulic legs.

[0010] Preferably, a control module is mounted on the slider for controlling the first motor, the second motor, the third motor and the hydraulic legs.

[0011] Preferably, a control module is mounted on the slider for controlling the first motor, the second motor, the third motor, the fourth motor and the hydraulic legs.

[0012] Preferably, the regulator includes a dial. A hollow inner ring is provided in the middle of the dial. A tubular level is provided inside the inner ring. A circular ring is provided outside the tubular level. The circular ring is embedded in the inner ring and rotates relative to the dial through a cross slope adjustment knob. A pointer is mounted on the circular ring and points to the scale of the dial.

[0013] To facilitate the understanding of the structure of the above detection trolley, the following usage method is provided:

[0014] First step, rough positioning: By operating the remote control, the detection trolley is driven to the cross-section to be detected. The detection trolley needs to be parked near the center line of the tunnel cross-section, and the left and right deviation from the tunnel center line should not be greater than 0.5 m.

[0015] Second step, leveling: According to the designed cross slope, by rotating the cross slope adjustment knob on the cross slope regulator, the pointer is aligned with the designed cross slope. An instruction is sent to the control module by operating the remote control. The control module makes the lifting legs jack up. By adjusting the telescopic amount of each leg, the bubble of the tubular level is centered. During the process of adjusting the level, after the level is adjusted in one direction, the turntable needs to be operated to rotate 90° to perform the leveling in the vertical direction.

[0016] Step 3: Precise positioning: Operate the remote control to send instructions to the control module. The control module makes the plane of the slide rail 1 approximately in the same cross-section as the cross-section to be detected. Then, set the rotation angle of the turntable through the remote control, generally 10° forward and backward is sufficient. Along with the rotation, turn on the laser rangefinders on both sides of the first slide rail. Add the values on both sides at each rotation angle and select the minimum value of the added values. This is the cross-section at this location. As the turntable rotates, the first slide rail automatically rotates to this angular position. At the same time, according to the results measured by the laser rangefinders on the left and right sides, automatically control the second motor to move the slider on the second slide rail so that the values measured by the left and right laser rangefinders are equal. Complete the precise positioning of the inspection trolley in the cross-section.

[0017] Step 4: Cross-section detection: Operate the remote control to start the first motor, so that the sliding part slides on the first slide rail. At the same time, start the laser rangefinder and record relevant data. When detecting the clearance size of the secondary lining cross-section, compare the collected data with the C value. If it is greater than or equal to the C value, it meets the requirements; if it is less than the C value, it does not meet the requirements. When detecting the primary support cross-section size, compare the collected data with the D value. If it is greater than or equal to the D value, it meets the requirements; if it is less than the D value, it does not meet the requirements. When detecting the excavation cross-section size, compare the collected data with the E value. If it is greater than or equal to the E value, it meets the requirements; if it is less than the E value, it does not meet the requirements.

[0018] Compared with the prior art, the beneficial effects of the present invention are as follows:

This intelligent tunnel cross-section inspection trolley and its use method are efficient, convenient, practical, highly innovative, accurate in the detection of tunnel cross-section (excavation face, primary support, secondary lining) sizes, improve the engineering detection efficiency, and ensure the construction progress.

[0020] 2. The inspection trolley has excellent adaptability to the detection of different lining structure cross-sections.

Specific implementation mode

[0027] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0028] Reference Figure 1 and Figure 3 , the intelligent tunnel section detection trolley 100 includes a first slide rail 101 and a second slide rail 106. A slider 105 is fixed at the bottom of the first slide rail 101. The slider 105 is slidably installed on the second slide rail 106 and is driven by a second motor 107 (the slider 105 and the second motor 107 can be connected by mechanisms such as a lead screw, and the slider 105 is driven to slide by the second motor 107), so that the first slide rail 101 can slide relative to the second slide rail 106. The first slide rail 101 has a degree of freedom in the X-axis direction (taking the tunnel section as the XZ plane and the extension direction of the tunnel as the Y-axis direction).

[0029] The second slide rail 106 is installed below and is installed on a turntable 110. The rotating surface of the turntable 110 is fixed to the bottom of the second slide rail 106. The turntable 110 is driven by a third motor 111 to rotate the upper rotating surface and the second slide rail 106. Both the first slide rail 101 and the second slide rail 106 have a degree of freedom around the Z-axis direction.

[0030] Rollers 112 are installed at the bottom of the turntable 110. The rollers 112 are driven by a fourth motor 113. Hydraulic support legs are also installed at the bottom of the turntable 110, and the hydraulic support legs can control the lifting of the turntable 110. Both the first slide rail 101 and the second slide rail 106 have degrees of freedom along the Z-axis and Y-axis directions.

[0031] Reference Figure 2, the first slide rail 101 is arranged concentrically with the inner clearance section of the tunnel secondary lining. A cross slope regulator 108 is arranged at the center of the circle. The cross slope regulator 108 is fixed on the slider 105. Distance measuring instruments 104 are arranged at both ends of the first slide rail 101, preferably laser distance measuring instruments. And the distance measuring instruments 104 are installed on the side wall of the sliding member 102 on the first slide rail 101. The sliding member 102 is driven by a first motor 103 (the sliding member 102 can be a moving trolley with wheels, and the first motor 103 drives the moving trolley to move along the track on the first slide rail 101). In this way, the laser distance measuring instrument can slide along the first slide rail 101, and then the distance between the tunnel contour and the first slide rail 101 can be measured.

[0032] The cross slope regulator 108 and the control module 109 are fixedly installed on the slider 105. The control module 109 can receive the instructions of the remote controller to control the first motor 103, the second motor 107, the third motor 111, the fourth motor 113 and the hydraulic support legs. In this way, the whole inspection trolley 100 can be controlled, reducing the number of workers and improving work efficiency.

[0033] Reference Figure 4 , among which, the cross slope regulator 108 includes a dial 1081. A hollow inner ring is arranged in the middle of the dial 1081. A tubular level 1083 is arranged in the inner ring. A ring is arranged outside the tubular level 1083. The ring is embedded in the inner ring and rotates relative to the dial 1081 through a cross slope adjustment knob 1084. A pointer 1082 is installed on the ring, and the pointer 1082 points to the scale of the dial 1081. During the inspection of the tunnel section, the inspection equipment needs to be in a horizontal or specific angle state to obtain accurate data. The cross slope regulator 108 can adjust the cross slope angle of the inspection equipment to match the designed cross slope of the tunnel or reach the horizontal state required for inspection. By rotating the cross slope adjustment knob 1084, the rotation of the tubular level 1083 is realized to meet the requirements for the inspection of different cross slope section widths.

[0034] The specific operation steps and related principles of the inspection trolley 100 are as follows:

[0035] The first step, rough positioning: By operating the remote controller, the inspection trolley 100 is driven to the section to be inspected. The inspection trolley 100 needs to be parked near the center line of the tunnel cross section. The left and right deviation of the center of the inspection trolley 100 from the tunnel center line should not be greater than 0.5 m. If the deviation is too large, the adjustment of the second slide rail 106 along the X-axis direction is limited and it cannot be adjusted to a proper position.

[0036] Step 2: Leveling: According to the designed cross slope, turn the cross slope adjustment knob 1084 on the cross slope adjuster 108 to align the pointer 1082 with the designed cross slope. Send a command to the control module 109 by operating the remote controller. The control module 109 jacks up the lifting legs 114. By adjusting the telescopic amount of each leg, make the bubble in the pipe level 1083 centered. During the leveling process, after leveling in one direction is completed, it is necessary to operate the turntable 110 to rotate 90° for leveling in the vertical direction. This operation is to keep the inspection trolley 100 horizontal with the slope surface.

[0037] Step 3: Fine positioning: Send a command to the control module 109 by operating the remote controller. The control module 109 makes the plane of the slide rail 1 approximately in the same cross section as the cross section to be detected. Then set the rotation angle of the turntable 110 through the remote controller, generally 10° forward and backward is enough. And during the rotation, turn on the laser rangefinders on both sides of the slide rail 101. Add the values on both sides at each rotation angle and select the minimum value of the added values. This operation is to find the cross section of the tunnel, and the position where the minimum value is found is the cross section of the tunnel. When the turntable 110 rotates, the slide rail 101 automatically rotates to this angular position; at the same time, automatically control the motor 2 107 according to the results measured by the laser rangefinders on the left and right sides, so that the slider 105 moves on the slide rail 106 with a movement value less than 0.5 m to make the values measured by the left and right laser rangefinders equal. This operation is to make the slide rail 101 located in the middle of the tunnel cross section to complete the precise positioning of the inspection trolley 100 in the cross section.

[0038] Step 4: Cross section detection: By operating the remote controller, start the motor 1 103 to make the sliding part 102 slide on the slide rail 101, and at the same time start the laser rangefinder to record relevant data. When detecting the clearance size of the secondary lining cross section, compare the collected data with the C value (the C value is the designed value). If it is greater than or equal to the C value, it meets the requirements; if it is less than the C value, it does not meet the requirements. When detecting the primary support cross section size, compare the collected data with the D value (D = C + the designed thickness of the secondary lining here). If it is greater than or equal to the D value, it meets the requirements; if it is less than the D value, it does not meet the requirements. When detecting the excavation cross section size, compare the collected data with the E value (E = C + the designed thickness of the secondary lining here + the designed thickness of the primary support here). If it is greater than or equal to the E value, it meets the requirements; if it is less than the E value, it does not meet the requirements.

Facts have proved that this tunnel intelligent cross section inspection vehicle and its use method are efficient, convenient, practical, highly innovative, highly applicable, accurate, improve the engineering inspection efficiency, and ensure the construction progress in the detection of tunnel cross section (excavation surface, primary support, secondary lining) sizes. It can not only reduce the construction cost, but also be applicable to the detection of different lining structure cross sections. In summary, it improves the adaptability, inspection quality and efficiency, realizes the concept of reducing the number of workers by mechanization, and practices green inspection.
