Description

Technical Field

[0001] The utility model relates to the technical field of tunnel engineering machinery, in particular to a tunnel inspection vehicle with a protective function. Background Art

[0002] The construction of tunnels plays an important role in improving the technical status of highways, shortening the operating distance, increasing transportation capacity, and reducing accidents. Tunnel geological hazards exposed during long-term operation often occur. Common tunnel structural diseases are mainly manifested as lining cracks, cross-section deformation, misalignment, water leakage, honeycomb surface, peeling and peeling. Due to the closed nature of the road space in the tunnel, the narrow space environment, large light changes, and unclear vision, in order to ensure driving safety, tunnels need to be inspected frequently, and problems must be repaired and maintained in time to avoid accidents. As a very important technical equipment in tunnel maintenance, tunnel inspection vehicles are used to detect key parameters in tunnels, ensure the safety of tunnel operations and improve the comfort of tunnel use. In the early stage of tunnel construction, tunnel inspection vehicles can be used to detect the integrity, geometric dimensions, internal damage, etc. of tunnel structures in detail 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 evaluate the stability and health of the tunnel structure, and to promptly discover and deal with potential damage or safety hazards. When upgrading, expanding or reinforcing tunnels, tunnel inspection vehicles can be used to evaluate the status of existing structures and provide data support for design plans. The tunnel inspection vehicle can also be used to conduct a detailed investigation of the accident scene after an accident occurs in the tunnel, analyze the cause of the accident, and provide technical support for accident handling.

[0003] However, if the tunnel inspection vehicle fails to clear obstacles in time during use or fails to detect and identify obstacles in the tunnel in time during nighttime inspection operations, the tunnel inspection vehicle may collide with obstacles in the tunnel. If the obstacle itself is large in size, it is easy to cause the tunnel inspection vehicle to be damaged during driving, affecting the inspection operation of the tunnel and more likely to threaten the safety of the inspection personnel.

[0004] Therefore, it is necessary to design a tunnel inspection vehicle that can mitigate the impact force of hitting obstacles and has a protective function. Utility Model Content

[0005] The utility model provides a tunnel inspection vehicle which can mitigate the impact force of hitting obstacles and has a protective function, aiming to solve one or more of the above problems and other potential problems.

[0006] The utility model provides a tunnel inspection vehicle with a protection function, characterized in that it comprises a vehicle body, a moving device arranged under the vehicle body and driving the vehicle body to move by rotation, and a protective device installed on the vehicle body for protecting the vehicle body, wherein the protective device comprises a protective member, a buffer mechanism arranged between the protective member and the vehicle body and used to reduce the impact force of obstacles on the vehicle body, and a deceleration mechanism arranged between the protective member and the moving device and decelerating the vehicle body according to the activity state of the protective member.

[0007] The utility model installs a protective device on the vehicle body, and the protective device can directly contact the obstacle when encountering an obstacle, so as to prevent the obstacle from directly touching the vehicle body and affecting the stability of the vehicle body. Furthermore, the protective device is divided into a protective member, a buffer mechanism and a deceleration mechanism. The protective member directly contacts the obstacle and converts the impact force of the obstacle on the protective member into a force acting on the buffer mechanism and the deceleration mechanism. The buffer structure uses the force obtained from the protective member to compress or release the internal structure of the buffer mechanism, thereby alleviating the impact force of the obstacle on the vehicle body and the impact force between the vehicle body and the protective device. The deceleration mechanism converts the force obtained from the protective member into a force acting on the moving device, thereby reducing or limiting the rotation speed of the moving device, slowing down the movement speed of the vehicle body to avoid continuous collision between the protective member and the obstacle.

[0008] The protective device of the utility model can prevent damage caused by direct collision between the vehicle body and the obstacle, and at the same time reduce the vibration amplitude of the vehicle body when it is hit by the obstacle, thereby ensuring the smooth operation of the vehicle body, the accuracy of detection and the safety of operators.

[0009] In some embodiments, the buffer mechanism includes a buffer tube having a hollow inner cavity connected to the side of the vehicle body, a buffer connector having one end fixedly connected to the protective member and the other end sleeved with the buffer tube, and an elastic component for elastically connecting the inner wall of the buffer tube and the buffer connector, and the buffer connector slides in the hollow inner cavity of the buffer tube as the protective member moves.

[0010] In an embodiment, when a collision occurs, an obstacle hits the protective member, and the protective member transmits the impact force to the elastic component through the buffer connecting member to compress the elastic component. After the elastic component is compressed, an elastic force opposite to the impact force is applied to the buffer connecting member, thereby reducing the vibration amplitude of the protective member after the force is applied, so that the force of the buffer connecting member and the protective member is balanced to reach a static state, thereby stopping the continuous collision between the protective member and the obstacle.

[0011] In some embodiments, the elastic component includes a buffer elastic member connected to the inner wall of the buffer tube and a pressure plate used to connect the buffer elastic member and a buffer connecting member.

[0012] In the embodiment, the pressure plate slides elastically in the hollow inner cavity of the buffer tube along with the buffer connector, and the impact force on the protective element is balanced by the elastic force of the buffer elastic element and the friction between the pressure plate and the inner wall of the buffer tube.

[0013] In some embodiments, the hollow inner cavity of the buffer tube is filled with damping fluid, and the pressure plate is provided with a plurality of damping holes. The damping fluid passes through the damping holes as the pressure plate moves in the hollow inner cavity to mitigate the impact force between the protective element and the vehicle body.

[0014] In the embodiment, in order to further increase the impact force consumed by the sliding of the pressure plate, a plurality of damping holes are provided on the pressure plate, and the continuous friction between the damping fluid and the damping holes is utilized to consume the kinetic energy of the protective element, reduce the collision loss inside the buffer mechanism, reduce the vibration amplitude of the protective element, and mitigate the impact force between the protective element and the vehicle body.

[0015] In some embodiments, the deceleration mechanism includes an electronically controlled deceleration component connected to the mobile device for controlling the rotation speed of the mobile device to decelerate the vehicle body, and a clamping deceleration component connected to the mobile device for using friction to reduce the rotation speed of the mobile device to decelerate the vehicle body.

[0016] Furthermore, a deceleration mechanism is provided to reduce the moving speed of the vehicle body, so that the vehicle body tends to be stationary, thereby avoiding continuous collision between the protective plate and obstacles.

[0017] In some embodiments, the electrically controlled deceleration component includes an electric component installed under the vehicle body for controlling the rotational speed of the mobile device, a touch component arranged on the electric component for controlling the electric component, a push-pull component having one end fixedly connected to the protective component and the other end contacting or separating from the touch component as the protective component moves, a support component arranged between the push-pull component and the touch component and slidably connected to the push-pull component for supporting the push-pull component to contact or separate from the touch component, and a compression component arranged on the push-pull component for compressing the support component.

[0018] In an embodiment, when there is an obstacle on the track, the protective member collides with the obstacle and then moves toward the inner side of the vehicle body, thereby driving the push-pull member to move toward the touch control member until it collides with the touch control member. The touch control member transmits a deceleration signal to the power member, and the power member controls the mobile device to decelerate, thereby reducing the moving speed of the mobile device, gradually stopping the vehicle body from moving, and preventing continuous collision between the vehicle body and the obstacle.

[0019] In some embodiments, the electrically controlled deceleration component also includes a fixed plate for connecting the power component and the touch component, and the support assembly includes a support plate with a through hole for the push-pull component to pass through and a support elastic component fixedly connected to the support plate and the fixed plate.

[0020] In some embodiments, the clamping deceleration component includes a clamping member arranged between the vehicle body and the mobile device for reducing the rotation speed of the mobile device by friction, a sliding assembly arranged under the vehicle body for supporting the sliding of the clamping member, and an extrusion member installed on the protective member and contacting or separating from the sliding assembly as the protective member moves, thereby controlling the clamping degree of the clamping member.

[0021] In the embodiment, the clamping member is installed on the sliding assembly and can slide along the sliding assembly. As the extruding member and the sliding assembly come into contact, the clamping member will move toward each other on the sliding assembly, thereby clamping the mobile device, and utilizing the friction between the clamping member and the mobile device to gradually reduce the rotation speed of the mobile device.

[0022] In some embodiments, the mobile device includes a driving shaft arranged under the vehicle body, connected to the electric component and rotated under the control of the electric component, driving wheels arranged at both ends of the driving shaft and rotating together with the driving shaft, driven wheels and driven shafts arranged under the vehicle body and rotating with the rotation of the driving wheels, and several support frames installed under the vehicle body with through holes for passing the driving shaft and the driven shaft.

[0023] In the embodiment, the driving shaft rotates under the control of the electric component, and the driving wheel rotates together with the driving shaft. A support frame is installed under the vehicle body, and the support frame connects the driving shaft, the driven shaft and the vehicle body. The driven wheel and the driven shaft are indirectly connected to the driving shaft through the vehicle body and rotate accordingly, thereby driving the vehicle body to move.

[0024] In some embodiments, the sliding assembly includes a sliding groove arranged under the vehicle body for installing the clamping member, a sliding tube fixedly connected to the vehicle body and having a hollow inner cavity, a clamping elastic member sleeved on the outside of the sliding tube, a sliding connector slidably connected to the inner cavity of the sliding tube, an operating plate connected to the clamping elastic member and the sliding connector and guiding the sliding connector to slide in the inner cavity of the sliding tube as the extrusion member is squeezed to compress or release the clamping elastic member, a pin groove through-through provided on the operating plate to guide the clamping member to slide in the sliding groove, and a sliding pin installed in the pin groove and capable of sliding in the pin groove as the operating plate compresses or releases the clamping elastic member; the clamping member is connected to the sliding pin and slides in the sliding groove as the sliding pin slides, thereby clamping the active rotating shaft.

[0025] In an embodiment, when there is an obstacle on the track and the protective member collides with the obstacle, the protective member drives the extrusion member to move toward the operating panel and squeeze the operating panel, so that the operating panel moves toward the direction of the vehicle body. At this time, the clamping member will move toward each other in the sliding groove under the guidance of the sliding pin, thereby clamping the active rotating shaft to reduce the rotation speed of the active rotating shaft, thereby reducing the moving speed of the vehicle body and achieving a deceleration effect.

[0026] In some embodiments, the tunnel inspection vehicle also includes an operating device arranged above the vehicle body, and the operating device includes a control panel arranged on the vehicle body for controlling the movement of the vehicle body, a seat and a passenger chair for an operator, and a box for placing tools.

[0042] 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.

[0043] This embodiment provides a tunnel inspection vehicle with a protection function, such as Figure 1 , Figure 2As shown, it is characterized in that it includes a vehicle body 1, a moving device 3 arranged under the vehicle body 1 and driving the vehicle body 1 to move by rotation, and a protective device 2 installed on the vehicle body 1 for protecting the vehicle body 1, the protective device 2 includes a protective member a, a buffer mechanism b arranged between the protective member a and the vehicle body 1 for reducing the impact force of obstacles on the vehicle body 1, and a deceleration mechanism c arranged between the protective member a and the moving device 3 and decelerating the vehicle body 1 according to the activity state of the protective member a.

[0044] like Figure 2 As shown, in this embodiment, a protective device 2 is installed on the vehicle body 1. The protective device 2 can directly contact the obstacle when encountering an obstacle, so as to prevent the obstacle from directly touching the vehicle body 1 and affecting the stability of the vehicle body 1. Furthermore, the protective device 2 is divided into a protective member a, a buffer mechanism b and a deceleration mechanism c. The protective member a directly contacts the obstacle and converts the impact force of the obstacle on the protective member a into a force on the buffer mechanism b and the deceleration mechanism c. The buffer structure uses the force obtained from the protective member a to compress or release the internal structure of the buffer mechanism b, thereby alleviating the impact force of the obstacle on the vehicle body 1 and the impact force between the vehicle body 1 and the protective device 2. The deceleration mechanism c converts the force obtained from the protective member a into a force on the moving device 3, thereby reducing or limiting the rotation speed of the moving device 3, and slowing down the moving speed of the vehicle body 1 to avoid continuous collision between the protective member a and the obstacle.

[0045] The protective device 2 of this embodiment can prevent damage caused by direct collision between the vehicle body 1 and obstacles, and at the same time reduce the vibration amplitude of the vehicle body 1 when hit by obstacles, thereby ensuring the smooth operation of the vehicle body 1 and ensuring the accuracy of detection and the safety of operators.

[0046] In some embodiments, Figure 3 As shown, the buffer mechanism b includes a buffer tube b1 with a hollow inner cavity connected to the side of the vehicle body 1, a buffer connector b2 with one end fixedly connected to the protective member a and the other end sleeved with the buffer tube b1, and an elastic component b3 for elastically connecting the inner wall of the buffer tube b1 and the buffer connector b2. The buffer connector b2 slides in the hollow inner cavity of the buffer tube b1 as the protective member a moves.

[0047] In the embodiment, the protective member a is slidably connected with the buffer tube b1 through the buffer connector b2, and the buffer connector b2 is elastically connected with the buffer tube b1 through the elastic component b3, so that the buffer connector b2 can elastically slide in the buffer tube b1. When a collision occurs, the obstacle hits the protective member a, and the protective member a transmits the impact force to the elastic component b3 through the buffer connector b2 to compress the elastic component b3. After the elastic component b3 is compressed, the elastic force opposite to the impact force is applied to the buffer connector b2 to reduce the vibration amplitude of the protective member a after the force is applied, so that the force of the buffer connector b2 and the protective member a is balanced to reach a static state, and the continuous collision between the protective member a and the obstacle is stopped.

[0048] In some embodiments, Figure 3 As shown, the elastic component b3 includes a buffer elastic member b31 connected to the inner wall of the buffer tube b1 and a pressure plate b32 used to connect the buffer elastic member b31 and the buffer connecting member b2.

[0049] In the embodiment, the buffer connector b2 applies a force to the buffer elastic member b31 through the pressure plate b32, so that the buffer elastic member b31 is compressed or released in the buffer tube b1, so that the buffer connector b2 slides back and forth in the hollow inner cavity of the buffer tube b1, and the pressure plate b32 elastically slides in the hollow inner cavity of the buffer tube b1 along with the buffer connector b2, and the elastic force of the buffer elastic member b31 and the friction force between the pressure plate b32 and the inner wall of the buffer tube b1 are used to balance the impact force received by the protective member a.

[0050] In some embodiments, the hollow inner cavity of the buffer tube b1 is filled with damping fluid, and a plurality of damping holes b33 are provided on the pressure plate b32. The damping fluid passes through the damping holes b33 as the pressure plate b32 moves in the hollow inner cavity to reduce the impact force between the protective member a and the vehicle body 1.

[0051] In the embodiment, in order to further increase the impact force consumed by the sliding of the pressure plate b32, a plurality of damping holes b33 are provided on the pressure plate b32. When the pressure plate b32 slides inside the buffer tube b1, the damping fluid in the hollow inner cavity of the buffer tube b1 will continuously pass through the damping holes b33. The continuous friction between the damping fluid and the damping holes b33 is utilized to consume the kinetic energy of the protective member a, reduce the collision loss inside the buffer mechanism b, reduce the vibration amplitude of the protective member a, and mitigate the impact force between the protective member a and the vehicle body 1.

[0055] In the embodiment, when there is an obstacle on the track, the protective member a collides with the obstacle and then moves toward the inside of the vehicle body 1, thereby driving the push-pull member c13 to move toward the direction of the touch member c12 until it collides with the touch member c12. The touch member c12 transmits a deceleration signal to the power member c11, and the power member c11 controls the moving device 3 to decelerate, thereby reducing the moving speed of the moving device 3, gradually stopping the vehicle body 1 from moving, and preventing the vehicle body 1 from continuously colliding with the obstacle.

[0056] In some embodiments, the electrically controlled deceleration component c1 also includes a fixed plate c16 for connecting the power component c11 and the touch component c12, and the support assembly c14 includes a support plate c141 having a through hole for the push-pull component c13 to pass through and a support elastic component c142 fixedly connected to the support plate c141 and the fixed plate c16.

[0059] In the embodiment, the clamping member c21 is installed on the sliding component c22 and can slide along the sliding component c22. As the extruding member c23 interferes with the sliding component c22, the clamping member c21 will move toward each other on the sliding component c22, thereby clamping the mobile device 3. The friction between the clamping member c21 and the mobile device 3 is used to gradually reduce the rotation speed of the mobile device 3.
