Description

Technical Field

[0001] This application relates to the technical field of railway tunnel lining quality inspection, and in particular to a device for rapid positioning of tunnel geological radar. Background Technology

[0002] Currently, during tunnel construction, ground-penetrating radar (GPR) is used for advanced forecasting to detect geological conditions near the tunnel. This facilitates the detection of geological factors such as faults, fracture zones, karst caves, and underground rivers, preventing these factors from affecting tunnel construction. GPR is a rapid, non-destructive, and high-resolution detection method that uses ultra-high frequency electromagnetic waves to detect the medium in front of the tunnel face. Based on the waveform, amplitude, and phase information of the transmitted electromagnetic waves received by the receiving antenna, the spatial location and morphological distribution of different media are analyzed and determined. Therefore, GPR advanced forecasting plays a very important role in tunnel construction, and auxiliary detection vehicles are required during the detection process.

[0003] In practice, the traditional approach usually requires three workers and a mobile inspection vehicle to mark the survey lines in advance. The markings are usually done manually, and about 200 linear meters can be marked per day, totaling 1,000 meters of survey lines. It would take three days to complete the daily inspection work. This not only consumes a lot of manpower and resources, but also has low work efficiency. Utility Model Content

[0004] In order to mark the position of the survey line in real time during tunnel lining quality inspection, thereby quickly locating and confirming the location of defects or blemishes, this application provides a device for rapid location detection using tunnel ground-penetrating radar.

[0005] The device for rapid positioning of tunnels using ground-penetrating radar provided in this application adopts the following technical solution:

[0006] A device for rapid positioning of tunnel ground-penetrating radar includes a mobile trolley and a lifting column. The lifting column is rotatably connected to the mobile trolley. A support frame is provided at the end of the lifting column away from the mobile trolley. The lifting column and the support frame are ball-jointed. A first adhesive assembly is provided on the support frame. The first adhesive assembly includes a tape roller, a compaction roller, and a frame. The tape roller is wrapped with measuring line tape. The tape roller is positioned in front of the compaction roller according to the travel direction of the mobile trolley, and the tape roller and the compaction roller are arranged parallel to each other. The frame includes a first support, a second support, and a main frame. The first support and the second support are both fixed to the main frame. The tape roller rotates relative to the first support, and the compaction roller rotates relative to the second support. The main frame is slidably connected to the support frame.

[0007] By adopting the above technical solution, a mobile trolley is used for marking survey lines during tunnel inspection. The mobile trolley can move freely inside the tunnel to find the location where the survey lines need to be pasted on the tunnel ceiling. Then, a lifting column is raised, and the support frame at the top of the lifting column can be adjusted to adapt to the curvature of the tunnel ceiling. After the location to be marked is determined, the tape roller on the support frame will paste tape along the length of the tunnel. Then, a compaction roller behind the tape roller will roll and compact the tape pasted inside the tunnel, making the tape pasted more firmly and stably. This not only saves manpower and resources but also improves the efficiency of survey line pasting.

[0008] Optionally, the first bracket includes a first rotating shaft and a protective plate. The first rotating shaft is fixed to the protective plate. The tape roller is sleeved on the first rotating shaft and rotates. Two protective plates are provided and are respectively provided on both sides of the tape roller. A pressure shaft is provided on the protective plate. The pressure shaft includes a pressure roller, a support rod, and a spring. The pressure roller is always in contact with the tape roller and rotates relative to the support rod. One end of the spring is fixed to the support rod and the other end is fixed to the protective plate. When tape is wrapped on the tape roller, the spring is always in a stretched state.

[0009] By adopting the above technical solution, the pressure shaft on the protective plate is constantly in contact with the tape roller due to the tension of the spring, which can provide a squeezing force to the tape wound on the tape roller and prevent the tape on the tape roller from falling off.

[0010] Optionally, the second support includes a second rotating shaft, a spring rod, and a first cylinder. The first cylinder is fixed to the main frame, the movable end of the first cylinder is fixed to the spring rod, the spring rod is fixed to the second rotating shaft, and the compaction roller is sleeved on the second rotating shaft and rotates. The compaction roller reciprocates in the vertical direction.

[0011] By adopting the above technical solution, after the tape on the conveyor roller is stuck to the top of the tunnel, the cylinder can drive the compaction roller to move upward, compacting and sticking the tape at the top of the tunnel. The spring rod can increase shock absorption and buffering for the rolling of the compaction roller.

[0012] Optionally, the support frame is further provided with a second adhesive component. The second adhesive component has the same structure as the first adhesive component, and the first adhesive component and the second adhesive component are parallel to each other and are both arranged parallel to the tunnel length direction. The first adhesive component and the second adhesive component can slide relative to the support frame. The support frame is provided with a screw assembly for driving the first adhesive component and the second adhesive component to slide.

[0013] By adopting the above technical solution, since it is sometimes necessary to draw multiple parallel survey lines at the same time when pasting survey lines in the tunnel, two sets of pasting components are set on the support frame, which can draw two survey lines at the same time, and the screw assembly can adjust the distance between the two sets of survey lines.

[0014] Optionally, the lead screw assembly includes a bidirectional screw and a guide rod. The bidirectional screw rotates relative to the support frame, and the guide rod is arranged parallel to the bidirectional screw and fixed to the support frame. The frame in the first adhesive assembly and the second adhesive assembly are respectively threadedly connected to the bidirectional screw and slidably connected to the guide rod.

[0015] By adopting the above technical solution, rotating the bidirectional screw causes the two sets of adhesive components to move threadedly with the frame in each of the two sets of adhesive components. Under the limiting and guiding action of the guide rod, the distance between the two sets of adhesive components can be adjusted to allow them to move closer or further apart.

[0016] Optionally, the mobile trolley is fixed with a housing, and a base is rotatably connected inside the housing. The rotation axis of the base is in the vertical direction. The lifting column is rotatably connected to the base, and the rotation axis of the lifting column is in the direction parallel to the base. A rotating component for driving the lifting column to rotate is provided inside the housing.

[0017] By adopting the above technical solution, the base on the mobile trolley rotates, which can drive the lifting column and the upper support frame to rotate as a whole, thereby enabling the pasting of measuring lines at multiple angles.

[0018] Optionally, the rotating assembly includes a rotating tooth, a rack, and a second cylinder. A sliding groove is provided on the base, and the rack is disposed in the sliding groove. The second cylinder is fixed to the base, and the movable end of the second cylinder is fixed to the rack. The bottom of the lifting column is fixed to the rotating tooth, and the rotating tooth meshes with the rack.

[0019] By adopting the above technical solution, the second cylinder drives the rack to move, and the rack meshes with the rotating tooth, which can drive the rotating tooth to rotate. The rotation of the rotating tooth can realize the swing of the lifting column and the support frame. In addition, the ball joint between the lifting column and the support frame can ensure that the two sets of adhesive components on the support frame are in a vertical state and will not tilt.

[0020] Optionally, two support rods are slidably connected to the lifting column. The two support rods are symmetrically arranged along the lifting column, and each support rod is hinged to the base.

[0021] By adopting the above technical solution, the stability of the lifting column can be increased when the support rod swings.

[0022] In summary, this application includes at least one of the following beneficial technical effects:

[0023] 1. The tape roller and compaction roller in the first bonding component can automatically bond the survey line to the top of the tunnel. The pressure roller on the tape roller can always be in contact with the tape wound on the tape roller. With the protection of the protective plate, the tape is prevented from falling. The spring rod on the compaction roller can provide shock absorption and cushioning when the compaction roller rolls the tape.

[0024] 2. The base on the mobile trolley rotates, which allows the lifting column and the adhesive components on the support frame to rotate horizontally. The rotating components can drive the lifting column to swing. At this time, the support rod can maintain the stability of the lifting column. In addition, the ball joint between the lifting column and the support frame can realize the multi-angle and multi-directional adhesive work of the two sets of adhesive components.

[0030] The following is in conjunction with the appendix Figures 1-4 This application will be described in further detail.

[0031] This application discloses a device for rapid location detection using tunnel geological radar.

[0032] refer to Figure 1 A device for rapid positioning of tunnel ground-penetrating radar includes a mobile trolley 1, a housing 11 fixed on the mobile trolley 1, a lifting column 2 installed inside the housing 11, the lifting column 2 penetrating the housing 11, a support frame 3 installed at the top, and a first adhesive component 4 and a second adhesive component 8 installed on the support frame 3. The mobile trolley 1 travels along the length of the tunnel, and the first adhesive component 4 and the second adhesive component 8 can mark multiple parallel survey lines at the top of the tunnel, facilitating rapid identification of broken parts in the tunnel.

[0033] refer to Figure 1 and Figure 2 A rotating motor is fixed on the mobile trolley 1, and a base 12 is fixed on the rotating motor. A rotating assembly 7 is set on the base 12. The rotating assembly 7 includes a rotating gear 71, a rack 72, and a second cylinder 73. A horizontal groove 121 is opened on the base 12, and the rack 72 slides in the groove 121. The second cylinder 73 is horizontally fixed to the base 12, and the movable end of the second cylinder 73 is fixed to the rack 72. A main shaft is horizontally fixed at the bottom of the lifting column 2. The main shaft is coaxially fixed with the rotating gear 71, and the rotating gear 71 meshes with the rack 72. When the second cylinder 73 is started, it pushes the rack 72 to reciprocate horizontally. The rack 72 drives the rotating gear 71 to rotate, which makes the lifting column 2 swing. Combined with the horizontal rotation of the base 12, the lifting column 2 can work in multiple directions and angles.

[0034] Two support rods 122 are hinged to the base 12. The two support rods 122 are symmetrically arranged along the lifting column 2. The end of the support rod 122 away from the base 12 is sleeved on the lifting column 2 and slidably connected to the lifting column 2, which can increase the stability when the lifting column 2 swings.

[0035] refer to Figure 1 The lifting column 2 is a common existing structure, so it will not be described in detail here. The top of the lifting column 2 is ball-jointed to the support frame 3. The first adhesive component 4 and the second adhesive component 8 on the support frame 3 have the same structure and are arranged side by side along the tunnel width. A screw assembly 6 is arranged between the first adhesive component 4 and the second adhesive component 8. The screw assembly 6 includes a double screw 61, a guide rod 62 and a drive motor 63. When the support frame 3 is horizontally set, the drive motor 63 is fixed to the support frame 3. The motor shaft of the drive motor 63 is fixed to the double screw 61. The double screw 61 rotates with the support frame 3. The guide rod 62 is arranged parallel to the bidirectional screw 61 and fixed to the support frame 3. The first adhesive component 4 and the second adhesive component 8 both include a frame 43. The two frames 43 are threadedly connected to the bidirectional screw 61 and are symmetrically distributed along the central axis of the bidirectional screw 61. At the same time, the two frames 43 are slidably connected to the guide rod 62. When the drive motor 63 starts, the bidirectional screw 61 rotates, and the two frames 43 move threadedly with the bidirectional screw 61. Under the limiting and guiding action of the guide rod 62, the distance between them can be adjusted to move closer or further apart.

[0036] refer to Figure 1The first adhesive component 4 and the second adhesive component 8 have the same structure and connection method. Here, we take the first adhesive component 4 as an example. The first adhesive component 4 includes a tape roller 41, a compaction roller 42 and a frame 43. The tape roller 41 is wrapped with measuring tape. According to the traveling direction of the moving trolley 1, the tape roller 41 is set in front of the compaction roller 42 and the tape roller 41 and the compaction roller 42 are parallel to each other. When the support frame 3 is set horizontally, the frame 43 includes a first bracket 431, a second bracket 432 and a main frame 433. The main frame 433 is set vertically and is slidably connected to the support frame 3. The first bracket 431 and the second bracket 432 are both set vertically and are fixed to the main frame 433 respectively.

[0037] refer to Figure 1 and Figure 3 The first support 431 includes a first rotating shaft 4311 and a protective plate 4312. The first rotating shaft 4311 is fixed to the protective plate 4312. The tape roller 41 is sleeved on the first rotating shaft 4311 and rotates. There are two protective plates 4312, which are respectively set on both sides of the tape roller 41. The diameter of the protective plate 4312 is larger than the diameter of the tape roller 41, which can effectively prevent the tape from scattering. A pressure shaft 5 is set on the protective plate 4312. The pressure shaft 5 includes a pressure roller 51, a support rod 52 and a spring 53. A groove is vertically set on the protective plate 4312. The spring 53 is vertically fixed in the groove. The top of the spring 53 is fixed to the support rod 52. The pressure roller 51 is set parallel to the tape roller 41 and rotates relative to the support rod 52. The side wall of the pressure roller 51 is always in contact with the tape roller 41. The spring 53 is always in a stretched state until the tape on the tape roller 41 is used up.

[0038] refer to Figure 1 and Figure 4 The second support 432 includes a second rotating shaft 4321, a spring 53 rod 4322, and a first cylinder 4323. The first cylinder 4323 is vertically fixed to the main frame 433. The movable end of the first cylinder 4323 is fixed to the spring 53 rod 4322. The spring 53 rod 4322 is fixed to the second rotating shaft 4321. The compaction roller 42 is sleeved on the second rotating shaft 4321 and rotates. After the tape on the tape roller 41 is pasted on the top of the tunnel, the compaction roller 42 moves vertically under the driving action of the first cylinder 4323, so that the compaction roller 42 abuts against the top of the tunnel. Under the movement of the moving trolley 1, the tape is firmly stuck.

[0039] The implementation principle of the tunnel ground-penetrating radar detection and rapid positioning device in this application embodiment is as follows: The mobile trolley 1 travels inside the tunnel. When it detects a location where there is a problem such as breakage at the top of the tunnel, it is necessary to attach the measuring line. The angle of the lifting column 2 is adjusted and the lifting column 2 is raised. The lifting column 2 and the support frame 3 are connected by a ball joint, which can keep the first attaching component 4 and the second attaching component 8 on the support frame 3 in contact with the top of the tunnel at all times. Under the action of the mobile trolley 1, the tape wound on the tape roller 41 is attached to the top of the tunnel. At the same time, the compaction roller 42 rolls and compacts the attached tape, thereby making the tape adhere more firmly. This realizes the automatic attachment of the measuring line tape, rapid positioning, and improves work efficiency.

[0040] The embodiments described in this specific implementation are preferred embodiments of this application and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
