Description

Technical Field

[0001] The utility model relates to the technical field of tunnel engineering machinery, in particular to a high-precision earthquake-resistant tunnel detection vehicle used for tunnel mapping detection. Background Art

[0002] Tunnel inspection vehicles are very important technical equipment in the maintenance of tunnels such as high-speed railways and railways. They are used to detect key parameters in tunnels, ensure the safety of tunnel operations and improve the comfort of tunnel use. In the early stages of tunnel construction, tunnel inspection vehicles can be used to conduct detailed inspections of the integrity, geometric dimensions, internal damage, etc. of the tunnel structure to ensure that the construction quality meets the design requirements. After the tunnel is built, tunnel inspection vehicles are also needed to regularly inspect the operating tunnels to assess the stability and health of the tunnel structure, and to promptly detect and deal with potential damage or safety hazards. When upgrading, expanding or reinforcing tunnels, tunnel inspection vehicles can be used to assess the status of existing structures and provide data support for design plans. Tunnel inspection vehicles can also be used to conduct detailed investigations of the accident site after an accident in the tunnel, analyze the cause of the accident, and provide technical support for accident handling.

[0003] However, since the tunnel inspection vehicle needs to move and measure in the tunnel when conducting surveying and inspection in the tunnel, the body of the vehicle may experience different degrees of bumps and vibrations during the movement, and the existing inspection vehicle itself may not have ideal anti-vibration effects. If the body of the vehicle vibrates during the surveying process, it may cause errors in the measurement results and affect the accuracy of the measurement data. In addition, the inspection vehicle is affected by continuous bumps and vibrations during the movement, and its own inspection components may be damaged, thereby reducing the service life of the inspection equipment and increasing the maintenance cost of the equipment.

[0004] Therefore, it is necessary to design a high-precision tunnel inspection vehicle that can adapt to the bumpy working environment and has high detection accuracy, and is used for tunnel mapping and inspection and is earthquake-resistant and shock-proof. Utility Model Content

[0005] The utility model provides a high-precision earthquake-resistant tunnel inspection vehicle for tunnel surveying and detection, aiming to solve one or more of the above problems and other potential problems. The utility model provides a high-precision earthquake-resistant tunnel inspection vehicle for tunnel surveying and detection, comprising a main body, a control host for controlling the movement of the main body, a power device for providing power, and a detection device for surveying and detection, characterized in that the main body comprises a mounting base for mounting the control host and the detection device, a moving device arranged below the mounting base for driving the movement of the mounting base, and an earthquake-resistant device arranged between the mounting base and the moving device for reducing the vibration amplitude of the mounting base, the earthquake-resistant device comprising a shock-absorbing chamber connected to the moving device and having a hollow inner cavity that can be compressed or released with the vibration of the moving device, and a pressure release portion installed in the shock-absorbing chamber and sliding in the shock-absorbing chamber with the compression or release of the hollow inner cavity of the shock-absorbing chamber to reduce the vibration amplitude of the mounting base.

[0006] The utility model provides an anti-vibration device between the mounting base and the mobile device, so as to reduce the vibration amplitude of the mounting base when the working environment is bumpy, so that the detection device installed on the mounting base can accurately perform mapping detection, thereby improving the detection accuracy.

[0007] The anti-vibration device of the utility model is connected to the mobile device. When the mobile device vibrates, the mobile device will apply pressure to the shock-absorbing chamber, thereby compressing or releasing the shock-absorbing chamber with a hollow inner cavity to reduce the vibration amplitude of the mounting base. Furthermore, as the hollow inner cavity of the shock-absorbing chamber is compressed or released, the pressure release part in the shock-absorbing chamber will slide, and the pressure of the mobile device on the shock-absorbing chamber will be partially converted into the elastic force of the pressure release part on the shock-absorbing chamber, thereby balancing the force of the shock-absorbing chamber, further reducing the vibration amplitude of the mounting base, and allowing the mounting base to remain stable in a bumpy working environment, reducing the impact of the bumpy environment on the precision of the detection device, and ensuring high-precision detection.

[0008] In some embodiments, the shock-absorbing chamber includes an outer chamber box fixedly connected to a mounting base and constituting an upper cavity of a hollow inner cavity, and an inner chamber box slidably fitted to an inner wall of the outer chamber box and constituting a lower cavity of the hollow inner cavity. The bottom of the inner chamber box is fixedly connected to a mobile device, and the outer wall of the inner chamber box slides against the inner wall of the outer chamber box as the mobile device vibrates, thereby compressing or releasing the hollow inner cavity.

[0009] In an embodiment, the bottom of the inner box is fixedly connected to the mobile device. When the environment is bumpy, the mobile device is subjected to force to vibrate up and down. Since the outer box and the inner box are slidably connected, the inner box will slide up and down on the inner wall of the outer box with the mobile device to compress or release the hollow inner cavity. Compared with a fixed connection, the impact of the vibration of the inner box on the state of the outer box is greatly reduced, so that the outer box is in a relatively stable state, thereby ensuring the stability of the mounting base in a bumpy environment.

[0010] In some embodiments, the pressure release portion includes a sliding component that slides along the inner wall of the shock absorbing chamber as the mobile device vibrates, and an elastic component connected to the sliding component for converting the vibration pressure of the mobile device.

[0011] In an embodiment, a sliding component is further provided in the shock absorbing chamber and can slide in the shock absorbing chamber along with the vibration direction of the mobile device. The sliding component compresses or releases the elastic component by sliding in the shock absorbing chamber, thereby converting part of the pressure of the mobile device on the shock absorbing chamber into the elastic force of the elastic component on the shock absorbing chamber, thereby putting the shock absorbing chamber in a state of force balance, gradually reducing the vibration amplitude of the shock absorbing chamber, releasing the pressure of the mobile device on the shock absorbing chamber, and ensuring the stability of the installation base.

[0012] In some embodiments, the sliding assembly includes a sliding plate that slides along the side inner wall of the shock absorbing bin as the mobile device vibrates, and a limiting column arranged on the sliding plate to limit the sliding range of the sliding plate. The top and bottom of the shock absorbing bin are correspondingly provided with limiting holes, and the sliding plate is slidably engaged with the limiting holes through the limiting columns to limit the sliding range of the sliding plate in the shock absorbing bin.

[0013] In the embodiment, the limiting column is slidably engaged with the limiting hole in the shock absorbing chamber, so that the sliding plate can slide up and down in the shock absorbing chamber and the center of the sliding plate is always on the same straight line. The sliding plate will not collide randomly in the shock absorbing chamber to increase the vibration amplitude of the shock absorbing chamber.

[0014] In some embodiments, the elastic component includes a spring sleeved on the limiting column, and both ends of the spring are respectively connected to the sliding plate and the shock absorbing chamber, and the spring is compressed or released as the hollow inner cavity of the shock absorbing chamber is compressed or released.

[0015] In some embodiments, the elastic component also includes a plurality of elastic plates arranged on both sides of the sliding plate, and the sliding plate is provided with a plurality of limit grooves. The two ends of the elastic plate are clamped in the limit grooves of the sliding plate, so that the middle section of the elastic plate is in contact with the top or bottom of the hollow inner cavity of the shock absorbing chamber.

[0016] In the embodiment, the elastic plate contacts the top or bottom of the hollow inner cavity of the shock absorbing chamber, exerts a force on the shock absorbing chamber, and the auxiliary spring balances the force of the shock absorbing chamber and supports the hollow inner cavity of the shock absorbing chamber to release the pressure on the shock absorbing chamber more quickly and reduce the vibration amplitude of the shock absorbing chamber.

[0017] In some embodiments, the moving device includes a supporting portion connected to the anti-seismic device and moving wheels axially connected to the supporting portion and driving the tunnel inspection vehicle to move on the tunnel through rotation.

[0018] In some embodiments, the support portion includes a support plate and a fixed plate fixedly connected to the anti-vibration device and axially connected to both ends of the moving wheel respectively, a motor axially connected to the moving wheel and providing power, and a fixed sleeve arranged on the fixed plate for accommodating the motor.

[0019] In some embodiments, the power device includes a battery for providing power, a battery box arranged under the mounting base for accommodating the battery, the battery box includes an outer cover box for placing the battery, and a protective plate rotatably connected to the outer cover box, and the protective plate is connected or detached from the outer cover box by a snap to achieve sealing or opening of the battery box.

[0020] By implementing the above technical solution, the utility model has the following advantages:

[0021] 1. The utility model sets an anti-vibration device between the mounting base and the mobile device to reduce the vibration amplitude of the mounting base when the working environment is bumpy, so that the detection device installed on the mounting base can accurately perform surveying and detection, thereby improving the detection accuracy.

[0022] 2. The anti-seismic device of the utility model is provided with a shock-absorbing chamber with a hollow inner cavity for compression or release to reduce the vibration amplitude of the mounting base. Furthermore, a pressure release part is provided to convert part of the pressure exerted by the mobile device on the shock-absorbing chamber into the elastic force exerted by the pressure release part on the shock-absorbing chamber, thereby balancing the force exerted on the shock-absorbing chamber, further reducing the vibration amplitude of the mounting base, and making the mounting base remain stable in a bumpy working environment, reducing the influence of the bumpy environment on the precision of the detection device, and ensuring high-precision detection.

[0023] 3. The pressure release part of the anti-seismic device of the utility model is provided with a limit column which is slidably engaged with the limit hole in the shock-absorbing chamber, so that the center of the pressure release part is in the same straight line during the pressure release process, the pressure release effect is stable, and the anti-seismic effect of the anti-seismic device is ensured to be stable.

[0031] The utility model is further described in detail below based on the accompanying drawings and specific embodiments.

[0032] It should be noted that the following implementation cases are only used to illustrate the technical solutions of the utility model, rather than to limit it. Those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or replace some of the technical features therein with equivalents. However, these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the scope of the technical solutions of the implementation cases of the utility model.

[0033] In the following description, terms such as "inside", "outside", "up", "down", "left", "right", etc. that indicate directions or positional relationships are only used to facilitate the description of the embodiments and simplify the description, and do not indicate or imply that the referred device or element must have a specific direction, be constructed and operated in a specific direction. Therefore, it should not be understood as a limitation on the present invention.

[0034] This embodiment provides a high-precision earthquake-resistant tunnel inspection vehicle for tunnel mapping and inspection, such as Figure 1As shown, it includes a main body 1, a control host 2 for controlling the movement of the main body 1, an electric device 3 for providing electric power and a detection device 4 for surveying and detecting, and is characterized in that the main body 1 includes a mounting base a for mounting the control host 2 and the detection device 4, a moving device b arranged below the mounting base a for driving the mounting base a to move, and an anti-vibration device c arranged between the mounting base a and the moving device b for reducing the vibration amplitude of the mounting base a, the anti-vibration device c includes a shock-absorbing chamber c1 connected to the moving device b and having a hollow inner cavity that can be compressed or released with the vibration of the moving device b, and a pressure release portion c2 installed in the shock-absorbing chamber c1 and sliding in the shock-absorbing chamber c1 with the compression or release of the hollow inner cavity of the shock-absorbing chamber c1 to reduce the vibration amplitude of the mounting base a.

[0035] like Figure 1 , Figure 2 As shown, the mobile device b can rotate on the track 5 to drive the main body 1 to move. When the working environment is bumpy, the mobile device b will vibrate with the degree of bumpiness of the track 5, causing the main body 1 to vibrate accordingly. In this embodiment, by setting an anti-vibration device c between the mounting base a and the mobile device b, the vibration amplitude of the mounting base a is reduced, so that the detection device 4 installed on the mounting base a can accurately perform surveying and detection, thereby improving the detection accuracy.

[0036] In the embodiment, the anti-vibration device c is connected to the mobile device b, and the anti-vibration device c is provided with a shock absorbing chamber c1 and a pressure releasing portion c2. When the mobile device b vibrates, the mobile device b applies pressure to the shock absorbing chamber c1, thereby compressing or releasing the shock absorbing chamber c1 having a hollow inner cavity to reduce the vibration amplitude of the mounting base a. Furthermore, as the hollow inner cavity of the shock absorbing chamber c1 is compressed or released, the pressure releasing portion c2 in the shock absorbing chamber c1 slides, and partially converts the pressure of the mobile device b on the shock absorbing chamber c1 into the elastic force of the pressure releasing portion c2 on the shock absorbing chamber c1, thereby balancing the force on the shock absorbing chamber c1, further reducing the vibration amplitude of the mounting base a, and allowing the mounting base a to remain stable in a bumpy working environment, thereby reducing the impact of the bumpy environment on the precision of the detection device 4, and ensuring high-precision detection.

[0037] In some embodiments, Figure 3 As shown, the shock-absorbing chamber c1 includes an outer chamber box c11 fixedly connected to the mounting base a and constituting an upper cavity of the hollow inner cavity, and an inner chamber box c12 slidably sleeved with the inner wall of the outer chamber box c11 and constituting a lower cavity of the hollow inner cavity. The bottom of the inner chamber box c12 is fixedly connected to the mobile device b, and the outer wall of the inner chamber box c12 slidably contacts the inner wall of the outer chamber box c11 with the vibration of the mobile device b, thereby compressing or releasing the hollow inner cavity.

[0038] In the embodiment, the bottom of the inner box c12 is fixedly connected to the mobile device b. When the environment is bumpy, the mobile device b is subjected to force to vibrate up and down. Since the outer box c11 and the inner box c12 are slidably connected, the inner box c12 will slide up and down on the inner wall of the outer box c11 with the mobile device b, thereby compressing or releasing the hollow inner cavity. Compared with a fixed connection, the impact of the vibration of the inner box c12 on the state of the outer box c11 is greatly reduced, so that the outer box c11 is in a relatively stable state, thereby ensuring the stability of the mounting base a in a bumpy environment.

[0039] In some embodiments, the pressure release portion c2 includes a sliding component c21 that slides along the inner wall of the shock absorbing chamber c1 as the mobile device b vibrates, and an elastic component c22 connected to the sliding component c21 for converting the vibration pressure of the mobile device b.

[0040] In the embodiment, the shock absorbing chamber c1 is further provided with a sliding component c21 that can slide in the shock absorbing chamber c1 along the vibration direction of the mobile device b. The sliding component c21 compresses or releases the elastic component c22 by sliding in the shock absorbing chamber c1, thereby converting part of the pressure of the mobile device b on the shock absorbing chamber c1 into the elastic force of the elastic component c22 on the shock absorbing chamber c1, thereby putting the shock absorbing chamber c1 in a state of force balance, gradually reducing the vibration amplitude of the shock absorbing chamber c1, releasing the pressure of the mobile device b on the shock absorbing chamber c1, and ensuring the stability of the mounting base a.

[0041] In some embodiments, the sliding assembly c21 includes a sliding plate c211 that slides along the inner side wall of the shock absorbing chamber c1 as the mobile device b vibrates, and a limiting column c212 arranged on the sliding plate c211 for limiting the sliding range of the sliding plate c211. The top and bottom of the shock absorbing chamber c1 are correspondingly provided with limiting holes c13. The sliding plate c211 is slidably engaged with the limiting hole c13 through the limiting column c212 to limit the sliding range of the sliding plate c211 in the shock absorbing chamber c1.

[0042] In the embodiment, the upper and lower surfaces of the sliding plate c211 are fixedly connected with a plurality of limiting columns c212, and the damping chamber c1 is provided with a plurality of limiting holes c13 for installation of the sliding plate c211. The limiting columns c212 are slidably engaged with the limiting holes c13 in the damping chamber c1, supporting the sliding plate c211 to slide up and down in the damping chamber c1 and the center of the sliding plate c211 is always on the same straight line, so that the sliding plate c211 will not collide randomly in the damping chamber c1 to increase the vibration amplitude of the damping chamber c1.

[0043] In some embodiments, the elastic component c22 includes a spring c221 sleeved on the limiting column c212, and both ends of the spring c221 are respectively connected to the sliding plate c211 and the shock absorbing chamber c1. The spring c221 is compressed or released as the hollow inner cavity of the shock absorbing chamber c1 is compressed or released.

[0044] In the embodiment, when the inner box c12 of the shock-absorbing box c1 moves upward under the pressure of the moving device b and applies an upward force to the outer box c11, at the same time, under the action of gravity, the sliding plate c211 slides downward, the clamping depth of the limiting column c212 arranged on the upper surface of the sliding plate c211 and the limiting hole c13 on the outer box c11 is reduced, and the spring c221 on the limiting column c212 on the upper surface of the sliding plate c211 is stretched by the combined action of the sliding plate c211 and the outer box c11, thereby applying a downward force to the outer box c11, so that the outer box c11 is subjected to force balance to reach a stable state and stops moving upward, and the hollow inner cavity is in a compressed state.

[0045] During the downward sliding of the sliding plate c211, the engagement depth between the limiting column c212 disposed on the lower surface of the sliding plate c211 and the limiting hole c13 on the inner bin box c12 increases, and the spring c221 disposed on the limiting column c212 disposed on the lower surface of the sliding plate c211 is compressed by the sliding plate c211 and the inner bin box c12. When a certain degree of compression is reached, the spring c221 exerts an upward force on the sliding plate c211, so that the sliding plate c211 is balanced in force and reaches a stable state and stops sliding down. Furthermore, the springs c221 above and below the sliding plate c211 continue to exert elastic force on the shock absorbing bin c1, so that the shock absorbing bin c1 is released from compression and returns to its original state.

[0046] In some embodiments, the elastic component c22 also includes a plurality of elastic plates c222 arranged on both sides of the sliding plate c211, and a plurality of limiting grooves c213 are provided on the sliding plate c211. The two ends of the elastic plate c222 are clamped in the limiting grooves c213 of the sliding plate c211, so that the middle section of the elastic plate c222 is in contact with the top or bottom of the hollow inner cavity of the shock absorbing chamber c1.

[0047] In the embodiment, the elastic plate c222 is a bendable elastic material with elastic force. The two ends of the elastic plate c222 are connected to the sliding plate c211 to make the elastic plate c222 in a bent state. The middle section of the elastic plate c222 is in contact with the top or bottom of the hollow inner cavity of the shock absorbing chamber c1, exerting a force on the shock absorbing chamber c1. The auxiliary spring c221 balances the force on the shock absorbing chamber c1 and supports the hollow inner cavity of the shock absorbing chamber c1 to release the pressure on the shock absorbing chamber c1 more quickly and reduce the vibration amplitude of the shock absorbing chamber c1.

[0048] In some embodiments, the moving device b includes a supporting portion b1 connected to the anti-seismic device c and a moving wheel b2 axially connected to the supporting portion b1 and driving the tunnel inspection vehicle to move on the tunnel through rotation.

[0049] In some embodiments, the supporting portion b1 includes a supporting plate b11 and a fixing plate b12 which are fixedly connected to the anti-vibration device c and are axially connected to both ends of the moving wheel b2 respectively, a motor b13 which is axially connected to the moving wheel b2 and provides power, and a fixing sleeve b14 which is arranged on the fixing plate b12 for accommodating the motor b13.

[0050] In some embodiments, the power device 3 includes a battery 31 for providing power, a battery box 32 arranged under the mounting base a for accommodating the battery 31, the battery box 32 includes an outer cover box 321 for placing the battery 31, and a protective plate 322 rotatably connected to the outer cover box 321, and the protective plate 322 is connected or detached from the outer cover box 321 by a buckle 323 to achieve the sealing or opening of the battery box 32.

[0051] In the embodiment, the output end of the motor b13 is axially connected to the moving wheel b2, and the battery 31 provides power to the motor b13, so that the output end of the motor b13 rotates to drive the moving wheel b2 to rotate to realize the movement of the main body 1.
