Description

Technical Field

[0001] This utility model relates to the field of tunnel inspection technology, and in particular to an image acquisition mounting bracket for a tunnel inspection vehicle. Background Technology

[0002] With the development of science and technology, significant breakthroughs have been made in subway construction technology. However, due to rapidly changing geological conditions and inadequate construction techniques by some teams, problems such as lining cracking, segment cracking, misalignment, and tunnel leakage may occur during construction. High-speed cameras are used for detection.

[0003] However, high-speed cameras are directly fixed on brackets, which are generally designed as fixed structures. Since tunnels are usually arched, if efficient tunnel inspection is to be achieved, the number of high-speed cameras must be increased. This results in a relatively long bracket design. However, fixed brackets are inconvenient to move with the inspection vehicle and are prone to hitting other objects in the tunnel, which can easily damage the high-speed cameras.

[0004] Therefore, how to provide a new type of oil filtration device has become a technical problem that needs to be solved by those skilled in the art. Utility Model Content

[0005] This utility model provides a solution that is significantly different from existing technologies, addressing the problem that existing technologies are too simplistic. To overcome the aforementioned shortcomings of existing technologies, this utility model provides an image acquisition mounting bracket for tunnel inspection vehicles, aiming to solve the problems mentioned in the background.

[0006] To achieve the above objectives, this utility model provides an image acquisition mounting bracket for a tunnel inspection vehicle, including a mounting platform. The mounting platform is fixed to the top of the tunnel inspection vehicle by bolts. A rotating mechanism is provided above the mounting platform. A drive module is fixed to the outer wall of the top of the mounting platform on one side of the rotating mechanism. The drive module is used to drive the rotating mechanism to rotate. A synchronously rotating core column is inserted into the middle of the rotating mechanism. A connector is provided above the core column, and a support frame is installed above the core column through the connector. Several high-speed cameras are arranged above the support frame.

[0007] Preferably, the rotary mechanism and the drive module are provided with a protective cover.

[0008] It protects the rotary mechanism and drive module, preventing dust accumulation.

[0009] Preferably, the drive module includes a motor fixed to the outer wall of the top of the mounting platform, and a transmission box is drivenly connected to the output shaft of the motor, with a drive gear disposed above the transmission box.

[0010] The motor drives the transmission box to rotate, and the transmission box decelerates and drives the drive gear to rotate.

[0011] Preferably, the rotary mechanism includes a housing fixed to the outer wall of the top of the mounting platform, a plane bearing is provided inside the housing, the core is inserted into the bottom of the housing and contacts the upper surface of the plane bearing, a guide ring and a gear ring are provided on the lower outer side of the core, a cover is provided above the guide ring and the cover is fixedly connected to the top of the housing.

[0012] The drive gear drives the gear ring to rotate, which in turn drives the core and guide ring to rotate synchronously. The core rotates inside the housing, and the guide ring is limited by the cover. The guide ring rotates stably below the cover, which stabilizes the rotation of the core. The core rotates above the plane bearing, ensuring the stability of the core rotation.

[0013] Preferably, the top of the core column is provided with an embedding groove, and the bottom of the support frame is inserted into the embedding groove.

[0014] The embedding groove set above the core column allows the crossbeam of the support frame to be installed inside the embedding groove, thereby improving the stability of the support frame installation.

[0015] Preferably, the connector includes a cover, and the outer walls on both sides of the cover are provided with a plurality of ear plates for inserting bolts.

[0016] The ear plate and bolts are used to fix the cover above the core column, thereby improving the connection capacity and strength between the support frame and the core column.

[0017] Preferably, the support frame is composed of a crossbeam, several support rods fixed to the top of the crossbeam, reinforcing rods fixed to both sides of the bottom of the crossbeam, and a top plate fixed to the top of the support rods. The top plate has an arc-shaped structure, and the high-speed camera is fixed to the outer wall of the top of the top plate.

[0018] The high-speed camera is fixed to the outer wall of the top of the roof slab. The reinforcing rods on both sides improve the support capacity for the crossbeams and ensure the stability of the overall support frame. The arc-shaped roof slab fits the arched structure of the tunnel better, which is more conducive to the placement of the high-speed camera and the inspection of the tunnel.

[0019] The beneficial effects of this utility model are:

[0020] When this utility model is in use, the rotating mechanism can rotate the support frame by 90 degrees under the drive of the drive module when the tunnel inspection vehicle is inspecting the tunnel, so that the support frame can drive the high-speed camera to inspect the arch of the tunnel more closely.

[0021] When the tunnel inspection vehicle is not inspecting the tunnel, the support frame can be set along the direction of the vehicle's travel to avoid collisions between the support frame and other objects in the tunnel. Attached Figure Description

[0032] Please see Figures 1 to 5 This utility model provides an image acquisition mounting bracket for a tunnel inspection vehicle, including a mounting platform 1, which is fixed to the top of the tunnel inspection vehicle by bolts. A rotating mechanism 3 is provided above the mounting platform 1. A drive module 2 is fixed to the outer wall of the top of the mounting platform 1 on one side of the rotating mechanism 3. The drive module 2 is used to drive the rotating mechanism 3 to rotate. A synchronously rotating core column 4 is inserted into the middle of the rotating mechanism 3. A connector 5 is provided above the core column 4, and a support frame 6 is installed above the core column 4 through the connector 5. Several high-speed cameras 7 are provided above the support frame 6.

[0033] In this embodiment, a mounting platform 1 is included. The mounting platform 1 is fixed to the top of the tunnel inspection vehicle by bolts. The tunnel inspection vehicle travels inside the tunnel, thereby enabling the high-speed camera 7 to perform inspection operations on the top of the tunnel.

[0034] In this embodiment, a rotary mechanism 3 is provided above the mounting platform 1;

[0035] Specifically, the rotary mechanism 3 includes a housing 31 fixed to the top outer wall of the mounting platform 1. A plane bearing 32 is installed inside the housing 31. The core 4 is inserted into the bottom of the housing 31 and contacts the upper surface of the plane bearing 32. A guide ring 35 and a gear ring 34 are provided on the lower outer side of the core 4. A cover 33 is provided above the guide ring 35 and is fixedly connected to the top of the housing 31. The gear ring 34 is driven to rotate by the drive gear 23. The gear ring 34 can drive the core 4 and the guide ring 35 to rotate synchronously. The core 4 rotates inside the housing 31. The cover 33 limits the guide ring 35. The guide ring 35 rotates stably below the cover 33, which plays a stabilizing role in the rotation of the core 4. The core 4 rotates above the plane bearing 32, ensuring the stability of the core 4's rotation.

[0036] In this embodiment, a drive module 2 fixed to the top outer wall of the mounting platform 1 is provided on one side of the rotary mechanism 3. The drive module 2 is used to drive the rotary mechanism 3 to rotate.

[0037] Specifically, the drive module 2 includes a motor 21 fixed on the top outer wall of the mounting platform 1, and a transmission box 22 is connected to the output shaft of the motor 21. A drive gear 23 is provided above the transmission box 22. When the motor 21 is started, it can drive the transmission box 22 to rotate. The transmission box 22 drives the top shaft to rotate, and the drive gear 23 is installed at the top of the shaft. At this time, the drive gear 23 rotates synchronously, which can drive the gear ring 34 of the rotary mechanism 3 to rotate, thereby driving the core column 4 to rotate.

[0038] In this embodiment, a synchronously rotating core column 4 is inserted into the middle of the rotary mechanism 3;

[0039] Specifically, the top of the core column 4 is provided with an embedding groove 41, and the bottom of the support frame 6 is inserted into the inside of the embedding groove 41. The crossbeam 61 of the support frame 6 is inserted into the inside of the embedding groove 41, which improves the stability of the connection between the support frame 6 and the top of the core column 4, and ensures the stability of the support frame 6 in supporting and installing the high-speed camera 7.

[0040] In this embodiment, a connector 5 is provided above the core post 4;

[0041] Specifically, the connector 5 includes a cover 51, and several ear plates 52 for inserting bolts are provided on both outer walls of the cover 51. After the crossbeam 61 is inserted into the embedded groove 41, the cover 51 is fixed by bolts, so that the cover 51 is fixed to the top of the core column 4, thereby strengthening the connection of the support frame 6 at the top of the core column 4.

[0042] In this embodiment, a support frame 6 is installed above the core column 4 via a connector 5, and several high-speed cameras 7 are arranged above the support frame 6.

[0043] The support frame 6 is composed of a crossbeam 61, several support rods 62 fixed to the top of the crossbeam 61, reinforcing rods 63 fixed to both sides of the bottom of the crossbeam 61, and a top plate 64 fixed to the top of the support rods 62. The top plate 64 has an arc-shaped structure. The high-speed camera 7 is fixed on the outer wall of the top of the top plate 64. The reinforcing rods 63 on both sides improve the support capacity of the crossbeam 61 and ensure the stability of the overall support frame 6. The arc-shaped structure of the top plate 64 fits the arch structure of the tunnel better, which is more conducive to the placement of the high-speed camera 7 and the inspection of the tunnel.

[0044] In this embodiment, a protective cover 8 is provided on the outside of the rotary mechanism 3 and the drive module 2, which protects the rotary mechanism 3 and the drive module 2 and prevents dust accumulation.

[0045] Work steps: 1. If Figure 1 As shown, the mounting platform 1 is fixed above the tunnel inspection vehicle with bolts, and the support frame 6 is kept in the same direction of travel as the tunnel inspection vehicle.

[0046] 2. When the tunnel inspection vehicle is driven into the tunnel, the drive module 2 drives the rotary mechanism 3 to move, which allows the core column 4 to rotate 90 degrees, driving the support frame 6 to rotate 90 degrees, and adjusting the position of the high-speed camera 7.

[0047] Third, as the tunnel inspection vehicle travels, the high-speed camera 7 is used to conduct an external inspection of the tunnel top. Because the support frame 6 fits the tunnel's arched structure more closely, the inspection effect is improved.

[0048] Fourth, after exiting the tunnel, the drive module 2 is restarted to drive the slewing mechanism 3 to rotate in the opposite direction, which can retract the support frame 6, thereby facilitating the transportation of the support frame 6 and the high-speed camera 7 by the tunnel inspection vehicle.

[0049] The above-disclosed embodiments are merely preferred embodiments of the present utility model and should not be construed as limiting the scope of the present utility model. Those skilled in the art can understand that implementing all or part of the above-described embodiments and making equivalent changes in accordance with the claims of the present utility model are still within the scope of the utility model.
