Description

Technical Field

[0001] This utility model relates to the field of tunnel technology, and in particular to a deformation detection device for the top of a highway tunnel. Background Technology

[0002] With the rapid development of transportation infrastructure, the number of highway tunnels is constantly increasing. Due to factors such as complex geological conditions, differences in construction quality, and long-term use, deformation problems such as settlement and cracks may occur in the tunnel roof. If these problems are not detected and dealt with in time, they will pose a serious threat to driving safety.

[0003] For example, a tunnel inspection device with publication number CN216012278U relates to the field of track inspection technology. This tunnel inspection device includes a vehicle body with a spring groove inside. The top of the spring groove is fixedly connected to one end of a second spring, and the other end of the second spring is fixedly connected to a support column. A telescopic rod is fixedly connected to the top of the support column. A fixing plate is fixedly connected to the bottom of the vehicle body, a battery is fixedly connected to the upper surface of the vehicle body, and an electric telescopic rod is fixedly connected to the top of the vehicle body. A platform is fixedly connected to the top of the electric telescopic rod, and a rack is fixedly connected to the top of the platform. One side of the support plate is fixedly connected to one end of the fixing spring. In this tunnel inspection device, the locking plate engages with the rack, thus fixing the slide plate and preventing it from moving backward, thereby avoiding the problem of the slide plate easily loosening. The deformation of the second spring cancels out the vibration generated during bumps, thus solving the problem of vibration damaging the inspection box when passing over bumpy roads. However, because the detection box of this device can only detect the deformation of the top of the highway tunnel, it cannot automatically switch between different detectors to detect the deformation of the top of the highway tunnel. It requires manual replacement, which is time-consuming, labor-intensive, and has low detection efficiency.

[0004] Therefore, a deformation detection device for the top of highway tunnels has been developed that can automatically switch between visual detectors and ultrasonic detectors, saving manpower and improving detection efficiency. Utility Model Content

[0005] To overcome the shortcomings of existing tunnel inspection devices, which can only detect deformation of the top of highway tunnels and cannot automatically switch between different detectors to detect the deformation, requiring manual replacement which is time-consuming, labor-intensive, and inefficient, this invention provides a highway tunnel top deformation detection device that can automatically switch between visual and ultrasonic detectors, saving manpower and improving detection efficiency.

[0006] The technical solution of this utility model is as follows: a deformation detection device for the top of a highway tunnel, comprising casters, a platform, a handle, a stabilizing mechanism, a telescopic mechanism, a protective mechanism, and a detection mechanism. Multiple casters are rotatably connected to the lower side of the platform, a handle is connected to the upper right side of the platform, a stabilizing mechanism is provided on the platform to stabilize it on the ground, a telescopic mechanism for lifting is provided on the platform, a detection mechanism for detecting deformation of the top of the highway tunnel is provided on the telescopic mechanism, and a protective mechanism for protecting the detection mechanism is also provided on the telescopic mechanism.

[0007] In one embodiment, the stabilizing mechanism includes a bidirectional motor, a first lead screw, a movable frame, a rotating connecting rod, and a shock absorber. The movable frame is slidably connected to the lower side of the middle of the vehicle board, and the bidirectional motor is connected to the middle of the movable frame. The output shaft of the bidirectional motor is connected to the first lead screw, and the first lead screw is rotatably connected to the movable frame. The front and rear sides of the vehicle board are rotatably connected to two left and right rotating connecting rods, and shock absorbers are rotatably connected between adjacent rotating connecting rods. The shock absorbers are slidably connected to the movable frame. The shock absorber on the front side is threadedly connected to the first lead screw on the right side, and the shock absorber on the rear side is threadedly connected to the first lead screw on the left side.

[0008] In one embodiment, the telescopic mechanism includes a first motor, a second lead screw, a movable rod, a telescopic folding frame, and a support plate. The first motor is connected to the inner right side of the vehicle plate, and the second lead screw is connected to the output shaft of the first motor. The second lead screw is rotatably connected to the vehicle plate. The movable rod is threaded onto the second lead screw, and the telescopic folding frame is rotatably connected between the movable rod and the vehicle plate. The support plate is rotatably connected to the upper left side of the telescopic folding frame, and the movable rod is slidably connected to the lower right side of the support plate. The movable rod is rotatably connected to the telescopic folding frame.

[0009] In one embodiment, the protective mechanism includes a detection box and a cover, with the detection box connected to the upper side of the support plate and the cover rotatably connected to the upper right side of the detection box.

[0010] In one embodiment, the detection mechanism includes a support block, a second motor, a rotating shaft, a rotating lifting linkage, a loading plate, a visual detector, and an ultrasonic detector. The support block is connected to the upper side of the support plate and is located inside the detection box. The second motor is connected to the upper side of the support plate and is located inside the support block. A rotating shaft is connected to the output shaft of the second motor. Rotating lifting linkages are rotatably connected to both sides of the rotating shaft. Loading plates are rotatably connected to the rotating lifting linkages. The loading plates are in contact with the support block. A visual detector is connected to the upper side of the right loading plate, and an ultrasonic detector is connected to the upper side of the left loading plate.

[0011] In one embodiment, the bidirectional motor, the first motor, the second motor, the ultrasonic detector, the visual detector, and the processor are electrically connected via a control module.

[0012] Beneficial effects: 1. By starting the second motor, the rotating lifting linkage is rotated, causing the loading plate to move along the bearing block, pushing the visual detector out of the detection box, so that the visual detector can detect the condition of the tunnel top surface, and then the ultrasonic detector can extend to detect internal defects or voids in the concrete. This achieves the effect of automatically switching between the visual detector and the ultrasonic detector, saving manpower and improving detection efficiency.

[0013] 2. This utility model starts a bidirectional motor, which drives the first lead screw to rotate, causing the shock absorbers to move closer to each other. This causes the rotating connecting rod to rotate to a vertical position, allowing the moving frame and shock absorbers to move downwards and contact the ground, stabilizing the vehicle platform in that position. This achieves the effect of easily stabilizing the vehicle platform and preventing it from moving during the inspection process. Attached Figure Description

The front shock absorber 25 is threadedly connected to the right first lead screw 22, and the rear shock absorber 25 is threadedly connected to the left first lead screw 22.

[0023] like Figure 1 and Figure 2 As shown, the telescopic mechanism 5 includes a first motor 51, a second lead screw 52, ​​a moving rod 53, a telescopic folding frame 54, and a support plate 6. The first motor 51 is connected to the inner right side of the vehicle plate 3. The second lead screw 52 is connected to the output shaft of the first motor 51. The second lead screw 52 is rotatably connected to the vehicle plate 3. The moving rod 53 is threaded onto the second lead screw 52. The telescopic folding frame 54 is rotatably connected between the moving rod 53 and the vehicle plate 3.

[0025] like Figure 1 and Figure 5As shown, the detection mechanism 8 includes a support block 81, a second motor 82, a rotating shaft 83, a rotating lifting linkage 84, a loading plate 85, a vision detector 86, and an ultrasonic detector 87.

After the support plate 6 reaches the designated height, the processor starts the second motor 82 through the control module, driving the rotating shaft 83 and the rotating lifting linkage 84 to rotate, causing the loading plate 85 to move along the support block 81, pushing the visual detector 86 out of the detection box 71, so that the visual detector 86 can detect the condition of the tunnel top surface. The above operation is repeated, causing the ultrasonic detector 87 to move to the right and extend to detect internal defects or voids in the concrete. This achieves the function of automatically switching between the visual detector 86 and the ultrasonic detector 87, saving manpower and improving detection efficiency.

It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of the present utility model, and these improvements and modifications should also be considered within the protection scope of the present utility model.
