Description

Technical Field

[0001] The present invention relates to the technical field of highway tunnel detection, and particularly relates to a device for detecting the deformation of a highway tunnel cross-section. Background Art

[0002] During the use of a highway tunnel, due to the influence of various factors such as geological conditions, natural disasters, and construction quality, different degrees of deformation and damage may occur. Through regular or irregular cross-section detection, the structural condition of the tunnel can be understood in a timely manner, potential safety hazards can be discovered, and corresponding measures can be taken for repair and reinforcement to ensure the safe operation of the tunnel. Cross-section detection can provide detailed data on the tunnel structure, including cross-section shape, size, deformation amount, etc., providing accurate basis and guidance for maintenance and repair work.

[0003] Currently, the commonly used methods for detecting the deformation of a highway tunnel cross-section mainly include the laser scanning method. By using a laser scanner to project a laser beam into the tunnel interior and receiving and recording the reflected laser signals, three-dimensional measurement of the tunnel cross-section can be achieved. When measuring the tunnel cross-section, multiple measuring points should be set in the tunnel, and each measuring point should be measured multiple times. Facing the measurement of multiple measuring points, the detection personnel need to carry the instrument and tripod to move. However, carrying the instrument and tripod to move will increase the operation difficulty. Especially in the case of long-term operation, the physical consumption of the detection personnel is large and they are prone to fatigue. Moreover, due to the large amount of dust in outdoor measurement, the instrument will be put into a box to prevent dust when it is idle, and it needs to be installed again when it is needed again, and the use steps are cumbersome.

[0032] In order to enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be further described in detail below with reference to the accompanying drawings.

[0033] The embodiments of the present application solve the problems in the prior art by providing a road tunnel section deformation detection device.

[0034] The technical solution in the embodiment of the present application is to solve the above problems, and the overall idea is as follows:

[0035] like Figure 1-Figure 8 As shown, a road tunnel section deformation detection device comprises:

[0036] Box body 6, a pair of first bearing seats 15 are connected to the bottom of the box body 6, a shaft 13 is rotatably connected inside the pair of first bearing seats 15, rollers 5 are connected to both ends of the shaft 13, a first driving mechanism is arranged outside the shaft 13, and a universal wheel 18 is connected to the bottom of the box body 6 away from the first bearing seats 15;

[0037] A pair of lifting mechanisms are provided on both side walls of the box body 6. The interior of the box body 6 is connected to a bottom plate 8 through the lifting mechanisms. The top of the bottom plate 8 is connected to a shell 9. The interior of the shell 9 is slidably connected to a square tube 27. The top of the square tube 27 is connected to a base 2. The top of the base 2 is connected to a laser scanner 1. The outer side of the square tube 27 is provided with a guide mechanism. The outer side of the shell 9 is provided with a second driving mechanism.

[0038] A pair of dust shielding plates 4 are slidably connected to the top of the box body 6, and a pair of traction mechanisms are arranged at the bottom of the dust shielding plates 4;

[0039] A handle 7 is connected to the back side of the box body 6 .

[0040] In some examples, a second slot 17 is provided at the bottom of the box body 6, and the first driving mechanism includes a third motor 23. One end of the output shaft of the third motor 23 is connected to the second pulley 22. The outer side of the second pulley 22 is sleeved with a belt 16. The belt 16 passes through the interior of the second slot 17 and is connected to the first pulley 14. The inner side of the first pulley 14 is fixedly connected to the shaft 13. By turning on the third motor 23, the second pulley 22 is driven to rotate. Through the connection between the second pulley 22, the belt 16 and the first pulley 14, the shaft 13 is conveniently driven to rotate, and then the rollers 5 on both sides are driven to rotate. Through the universal wheel 18 set at the bottom of the box body 6, the laser scanner 1 can be conveniently driven to move flexibly.

[0041] In some examples, the lifting mechanism includes a second motor 21, the bottom of the second motor 21 is fixedly connected to the box body 6, one end of the output shaft of the second motor 21 is connected to the reciprocating screw 20, the top of the reciprocating screw 20 is rotatably connected to the second bearing seat 24, one side of the second bearing seat 24 is fixedly connected to the box body 6, the outer side of the reciprocating screw 20 is sleeved with a ball nut pair 25, the outer side of the ball nut pair 25 is fixedly connected with a fixing sleeve 26, one side of the fixing sleeve 26 is fixedly connected to the base plate 8, and the second motor 21 is turned on to drive the reciprocating screw 20 to rotate, thereby driving the fixing sleeve 26 on the outer side of the ball nut pair 25 and the base plate 8 to move up and down, thereby adjusting the height of the laser scanner 1 above the base plate 8.

[0042] In some examples, a third slot 28 is provided on all four sides of the shell 9, and the guide mechanism includes three guide sleeves 32, one side of the guide sleeve 32 is fixedly connected to the square tube 27, and the other side of the guide sleeve 32 passes through the interior of the third slot 28, and the other side of the guide sleeve 32 is slidably connected to a guide rod 19, the end of the guide rod 19 is fixedly connected to the base plate 8, and the top of the guide rod 19 is connected to a fixing plate 29, and one side of the fixing plate 29 is fixedly connected to the shell 9. Through the connection between the guide sleeve 32 and the guide rod 19, the height of the laser scanner 1 can be further adjusted while ensuring its stability.

[0043] In some examples, the second driving mechanism includes a first motor 10, one end of the output shaft of the first motor 10 is connected to a gear 30, the outer side of the gear 30 is meshed with a rack 31, the back side of the rack 31 is fixedly connected to the square tube 27, and the first motor 10 is turned on to drive the gear 30 to rotate, thereby driving the rack 31 and the square tube 27 to rise and fall, thereby facilitating further adjustment of the height of the laser scanner 1.

[0044] In some examples, the position of the gear 30 corresponds to the position of the third slot 28 .

[0045] In some examples, the traction mechanism includes a traction arm 3, wherein the second axial hole 37 and the first axial hole 36 are respectively provided at both ends of the traction arm 3, and the first U-shaped rod 34 and the second U-shaped rod 35 are rotatably connected inside the second axial hole 37 and the first axial hole 36, respectively. The two ends of the first U-shaped rod 34 are fixedly connected to the bottom plate 8, and the two ends of the second U-shaped rod 35 are fixedly connected to the dust baffle 4. Through the connection between the traction arm 3, the first U-shaped rod 34 and the second U-shaped rod 35, the dust baffle 4 on the top of the traction arm 3 can be moved synchronously while the bottom plate 8 is lifted. When the bottom plate 8 is lifted, a pair of traction arms 3 connected to the top of the bottom plate 8 at both sides are moved back to back, and the dust baffles 4 on both sides are driven to slide back to back, so as to facilitate the laser scanner 1 to be moved out of the box 6. Conversely, when the bottom plate 8 drives the laser scanner 1 to descend, it drives the traction arms 3 on both sides to move toward each other. When the laser scanner 1 descends to the inside of the box 6, the dust baffles 4 on both sides can fit tightly together.

[0046] In some examples, the length of the traction arm 3 is consistent with the length of the reciprocating screw 20. When the base plate 8 on the outside of the ball nut pair 25 moves up and down along the outside of the reciprocating screw 20, the traction arm 3 is synchronously driven to move. By setting the length of the traction arm 3 to be consistent with the length of the reciprocating screw 20, it is convenient for the ball nut pair 25 to move to the bottom of the reciprocating screw 20, and the dust baffles 4 on both sides that are rotatably connected to the top of the traction arms 3 on both sides can fit tightly together to prevent dust from entering the box 6 through the gaps in the dust baffles 4 on both sides.

[0047] In some examples, a pair of first slot holes 12 are correspondingly opened on both sides of the top of the box body 6, and the traction arm 3 passes through the interior of the first slot hole 12. The first slot hole 12 is set to an inverted convex shape. By setting the first slot hole 12 to an inverted convex shape, it is convenient for the traction arm 3 to move along the first slot hole 12, and the U-shaped rod at one end of the traction arm 3 can pass through the interior of the first slot hole 12.

[0048] In some examples, a pair of slide grooves 33 are provided on both sides of the top of the box body 6 away from the first slot hole 12, and a pair of sliders 11 are slidably connected inside the slide grooves 33. The tops of the sliders 11 are fixedly connected to the dust baffle 4. The connection between the slide grooves 33 and the sliders 11 facilitates the parallel sliding of the dust baffles 4 on both sides.

[0049] The present invention provides a box 6 to facilitate the storage and preservation of the laser scanner 1. When the laser scanner 1 is needed, the second motor 21 is driven to conveniently lift the bottom plate 8, and at the same time, the dust shields 4 on both sides slide back to back, so that the laser scanner 1 is conveniently transferred out of the box 6. Conversely, when it is not needed, the bottom plate 8 is adjusted to be lowered to drive the laser scanner 1 to be stored in the box 6, and at the same time, the dust shields 4 on both sides slide toward each other to cover the top of the laser scanner 1, which can play a dust-blocking effect when idle, avoiding the need for repeated disassembly and assembly. At the same time, when the position of the laser scanner 1 needs to be adjusted, the third motor 23 is turned on to facilitate the rotation of the rollers 5 on both sides, and the universal wheels 18 provided at the bottom of the box 6 are convenient to drive the laser scanner 1 to move flexibly, eliminating the need for detection personnel to carry the instrument and the tripod to move, thereby greatly reducing the labor intensity of the detection personnel.

It is undoubted that those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
