Description

Technical Field

[0001] This utility model relates to the technical field of bridge inspection equipment, specifically a horizontally movable bridge inspection device. Background Technology

[0002] A bridge generally refers to a structure erected over rivers, lakes, or seas to allow vehicles and pedestrians to pass smoothly. To adapt to the rapidly developing modern transportation industry, the term "bridge" has also been extended to refer to structures built across mountains, challenging geological conditions, or to meet other transportation needs, making travel more convenient. A bridge typically consists of a superstructure, substructure, supports, and ancillary structures. The superstructure, also known as the bridge span structure, is the main structure that crosses obstacles. The substructure includes abutments, piers, and foundations. Supports are force-transmitting devices installed at the points where the bridge span structure supports the piers or abutments. Ancillary structures include approach slabs, tapered slopes, revetments, and diversion works. Currently, during the service life of bridges, regular manual inspection of the bridge surface is required, which is inefficient and inconvenient.

[0003] According to a search report from a novelty search agency, announcement number CN211472167U discloses a horizontally movable bridge inspection device, including a drive box, a drive mechanism, an adjustment mechanism, and a limiting mechanism. The drive box has a drive groove on its top, the inner circumference of which is fixedly welded to the outer circumference of a fixed bearing seat. The inner ring of the fixed bearing seat is equipped with a drive mechanism connected to the drive box. A sliding groove is provided on one side inside the drive box, and an adjustment mechanism connected to the lower half of the drive mechanism is located within the sliding groove. A drive seat is fixedly welded to the bottom of the adjustment mechanism, and two sets of symmetrical drive blocks are fixedly welded to the bottom of the drive seat. Adaptive limiting mechanisms are provided on both sides of the bottom of the drive seat away from the drive blocks. A camera is positioned between the two sets of limiting mechanisms, and the camera's base is connected to the bottom of the drive seat via fasteners. This horizontally movable bridge inspection device can be adjusted and limited as needed, facilitating periodic inspection of the bridge surface.

[0004] The aforementioned technology discloses a horizontally movable bridge inspection device. Through a drive motor, a drive box, and a drive component formed by gears and racks inside the drive box, it can drive a camera to move and adjust horizontally. The camera records the bridge surface in real time, and staff only need to periodically replace the camera's memory card to perform regular inspections of the bridge surface. However, it still has the following shortcomings: 1. The drive application method, where the front opening of the drive box and the gear and rack drive component inside are directly exposed, allows dust and impurities to easily enter and clog the gears and racks over time, affecting stable drive operation and resulting in unsatisfactory long-term drive stability; 2. It cannot automatically clean and remove dust from the outside of the camera during large-scale monitoring and recording while moving horizontally. With prolonged use, lightweight dust easily accumulates on the outside of the camera, affecting the clarity of the monitoring and recording. Improvements are needed. Therefore, this application proposes a horizontally movable bridge inspection device to solve the above-mentioned problems. Utility Model Content

The staff only needs to replace the camera's memory card periodically, eliminating the need for frequent manual observation and recording of the bridge surface, thus improving detection efficiency.

[0020] 2. In addition, by using the bottom of the drive box as an opening, the accumulation of dust and impurities is reduced.

[0021] 3. By combining the dustproof reciprocating screw drive assembly, the round box, the leveraged air supply assembly, and the cleaning pipe, the dust can be automatically blown away from the outside of the camera during large-scale monitoring and recording while moving horizontally. The integrated air blowing creates conditions that prevent light dust from settling and accumulating, reducing the impact of light dust settling and accumulating on the outside of the camera and affecting the clarity of the monitoring and recording, thus improving the clarity of the monitoring and recording.

[0022] This utility model incorporates a series of structures to facilitate the reciprocating horizontal movement of the camera for large-scale real-time monitoring and recording of the bridge surface. The drive unit features an opening at the bottom, which, combined with two telescopic dust-proof sleeves, continuously surrounds the reciprocating screw to prevent dust accumulation and blockage, thus reducing the likelihood of dust and impurities falling in and jamming the screw, improving long-term stable anti-jamming performance.

[0034] Camera 5 is installed at the bottom of the circular box 3. Multiple cleaning pipes 301 surround camera 5, and the bottom ends of the multiple cleaning pipes 301 are all tilted towards camera 5. The camera 5 is used to move with the circular box 3 when it moves back and forth laterally, and to record the bridge surface in real time when it is turned on. The staff can replace the memory card of camera 5 periodically.

[0035] The leveraged air supply component is installed on the right side of the drive box 1 and is fixedly connected to the dustproof reciprocating screw drive component, and is also connected and fixed to the right side of the round box 3. The leveraged air supply component is used to generate wind force by leveraging the rotational force of the dustproof reciprocating screw drive component and supply air to the round box 3. Multiple cleaning pipes 301 are provided to blow away dust from the outside of the camera 5 during horizontal movement, reducing the environment where dust settles and accumulates on the outside of the camera 5, thereby improving the clarity of monitoring and recording.

[0036] It should be noted that both the camera 5 and the drive motor 101 are equipped with switches and are electrically connected to the external drive power supply via flexible wires.

[0037] Specifically, the dustproof reciprocating screw drive assembly includes two T-shaped slide rails 201 fixedly connected to the top of the drive box 1. The same movable sleeve 2 is slidably connected to the two T-shaped slide rails 201. The top of the movable sleeve 2 has two T-shaped slide grooves with openings on both sides. The inner wall of the T-shaped slide groove is slidably connected to the corresponding T-shaped slide rail 201, which serves to guide the lateral sliding of the movable sleeve 2. The right end of the output shaft of the drive motor 101 is fixedly connected to a reciprocating screw 202. A reciprocating sleeve 203 is threaded on the reciprocating screw 202. The reciprocating sleeve 203 is fixedly connected between the top inner wall and the bottom inner wall of the movable sleeve 2. Telescopic dustproof rubber sleeves 204 are fixedly connected between the two sides of the movable sleeve 2 and the two sides of the inner wall of the drive box 1, respectively. The reciprocating screw 202 is located inside the two telescopic dustproof rubber sleeves 204. The bottom of the movable sleeve 2 is fixedly connected to the top of the round box 3.

[0038] In this embodiment: the movable sleeve 2, T-shaped slide rail 201, reciprocating screw 202, reciprocating sleeve 203, and telescopic dustproof rubber sleeve 204 are configured to cooperate. The drive motor 101 drives the reciprocating screw 202 to rotate. The rotation of the reciprocating screw 202 drives the reciprocating sleeve 203 to move laterally to the right and left. The reciprocating sleeve 203 drives the movable sleeve 2 to slide laterally on the two T-shaped slide rails 201 and to compress or stretch the two telescopic dustproof rubber sleeves 204. The movable sleeve 2 drives the circular box 3 to move laterally to the right and left. The two telescopic dustproof rubber sleeves 204 always surround the reciprocating screw 202 to prevent dust and impurities from getting stuck in the reciprocating screw 202 and affecting the operation of the drive, thus ensuring a long-term stable anti-jamming operation.

[0039] Furthermore, the leveraged air supply assembly includes a rotating shaft 4 rotatably mounted on the inner right wall of the drive housing 1. A circular through-hole is provided on the inner right wall of the drive housing 1, and a bearing is fixedly fitted inside the through-hole. The inner ring of the bearing is fixedly fitted to the outer side of the rotating shaft 4, thus achieving the effect of rotating the shaft 4. The left end of the rotating shaft 4 is fixedly connected to the right end of the reciprocating screw 202. An arc-shaped baffle plate 401 is fixedly connected to the top right side of the drive housing 1, and a circular tube 402 is fixedly connected to the bottom of the arc-shaped baffle plate 401. The left end of the circular tube 402... A cylindrical filter screen 403 is fixedly connected to the right side of the drive box 1 by screws. The right end of the rotating shaft 4 extends into the round tube 402. Multiple fan blades 404, all located inside the round tube 402, are fixedly connected in a ring at equal intervals on the outside of the rotating shaft 4. When the fan blades 404 rotate, the right side is the blowing part and the left side is the exhaust part. The right end of the round tube 402 is connected to and fixedly connected to a U-shaped air guide pipe 405 with a cover-shaped structure on the upper left side. A flexible tube 406 is fixedly connected between the lower left end of the U-shaped air guide pipe 405 and the right side of the round box 3.

[0040] In this embodiment, the rotating shaft 4, arc-shaped baffle plate 401, circular tube 402, cylindrical filter screen 403, fan blades 404, U-shaped air guide duct 405, and flexible tube 406 are arranged in combination. The flexible tube 406 is flexible enough to bend and be pulled when the circular box 3 moves laterally, providing the circular box 3 with the conditions for lateral displacement. When the reciprocating screw 202 rotates, its rotational force is used to drive the rotating shaft 4 to rotate. The rotating shaft 4 drives multiple fan blades 404 to rotate. When the multiple fan blades 404 rotate, they draw in external air through the cylindrical filter screen 403 and blow it into the U-shaped air guide duct 405. The cylindrical filter screen 403 filters and intercepts external particulate impurities. The blown air is supplied into the circular box 3 through the flexible tube 406, realizing the effect of generating wind power and supplying air into the circular box 3 by using the rotational force of the reciprocating screw 202.

[0041] It should be noted that the cylindrical filter 403 is made of fiber or non-woven material and can filter dusty air.

[0042] Furthermore, the bottom of the round box 3 is fitted with an internally threaded sleeve 302 with a sealing structure at the top. The bottom of the round box 3 has an insertion hole that is fixedly connected to the outside of the internally threaded sleeve 302. An elastic rubber pad 303 is bonded and fixed on the top inner wall of the internally threaded sleeve 302. The top of the camera 5 is fixedly connected with a threaded post 501. The threaded post 501 is threaded into the internally threaded sleeve 302. The top of the threaded post 501 is pressed tightly against the bottom of the elastic rubber pad 303.

[0043] In this embodiment, the threaded post 501, the inner threaded sleeve 302, and the elastic pad 303 are designed to work together to facilitate easy connection or disconnection of the threaded post 501 and the inner threaded sleeve 302 by rotating the camera 5. The elastic pad 303 is used to elastically tighten and dampen the threaded post 501 during connection to prevent loosening. The elastic pad 303 is also designed to allow the operator to adjust the orientation of the camera 5 appropriately during screwing, as its elasticity allows for changes in the degree of compression.

[0044] The usage method of this embodiment is as follows: When using the horizontally movable bridge detection device, the drive box 1 is installed at a suitable position on the top of the bridge using fixing bolts. After installation, the threaded post 501 at the top of the camera 5 is screwed into the inner threaded sleeve 302, and the elastic rubber pad 303 is squeezed tightly. The elasticity of the elastic rubber pad 303 provides elastic tension and damping to prevent loosening of the threaded post 501 during screwing. The elasticity of the elastic rubber pad 303 allows the operator to adjust the orientation of the camera 5 appropriately during screwing, thus achieving the installation of the camera 5. After connection, it can be used. Turn on the drive motor 101 and the camera 5. The drive motor 101 drives the reciprocating screw 202 to rotate. The rotation of the reciprocating screw 202 drives the reciprocating sleeve 203 to move horizontally to the right and left. The reciprocating screw sleeve 203 drives the movable sleeve 2 to slide laterally back and forth on the two T-shaped slide rails 201, and compresses or stretches the two telescopic dustproof rubber sleeves 204 back and forth. The movable sleeve 2 drives the round box 3 to move laterally back and forth, and the round box 3 drives the camera 5 to move laterally back and forth, so as to carry out large-scale real-time monitoring and recording of the bridge surface. The staff only needs to replace the memory card of the camera 5 periodically, without the need for frequent manual observation and recording of the bridge surface, thus improving the detection efficiency. Moreover, by using the bottom opening of the drive box 1, the phenomenon of dust and impurities falling and accumulating is reduced. In conjunction with the two telescopic dustproof rubber sleeves 204 always surrounding the reciprocating screw 202 to prevent dust and impurities from getting stuck in the reciprocating screw 202 and affecting the drive operation, the long-term stable anti-jamming operation effect is improved.

[0045] The flexible tube 406, with its flexibility and bendability, allows the circular box 3 to move laterally, providing conditions for lateral displacement. When the reciprocating screw 202 rotates, its rotational force drives the rotating shaft 4, which in turn drives multiple fan blades 404. As the fan blades 404 rotate, they draw in external air through the cylindrical filter 403 and blow it into the U-shaped air duct 405. The cylindrical filter 403 filters and intercepts external particulate impurities. The blown air is then supplied into the circular box 3 through the flexible tube 406. This achieves the effect of generating wind and supplying air into the circular box 3 using the rotational force of the reciprocating screw 202. The air is then blown around the camera 5 through multiple cleaning pipes 301 to remove dust, achieving automatic dust removal from the outside of the camera 5 during large-scale lateral movement and monitoring. This integrated air blowing creates conditions that prevent the static accumulation of lightweight dust, reducing the likelihood of dust settling on the outside of the camera 5 and affecting the clarity of the monitoring recording, thus improving the clarity of the monitoring recording.

[0046] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
