Description

Technical Field

[0001] This utility model relates to the field of road and bridge surveying technology, specifically a civil engineering road and bridge surveying device. Background Technology

[0002] Road and bridge surveying is a crucial step in ensuring the safety, stability, and long-term use of bridges. It involves multiple disciplines and technical fields, including but not limited to geological surveys, topographical surveys, structural inspections, and material testing. By comprehensively inspecting the bridge structure, its current condition is determined, potential problems or damaged areas are identified, and based on the survey results, a reasonable maintenance plan is developed, and appropriate repair or reinforcement solutions are selected.

[0003] A search revealed Chinese patent CN222189152U, which discloses a device for detecting cracks in civil engineering road bridges. The device includes two trolleys, each with a first and second housing fixedly connected to it. A detection component is housed within both the first and second housings. This component includes a rotating shaft, pull ropes, a fixing ring, and a camera. The two rotating shafts are rotatably connected to the interiors of the first and second housings, respectively. Two pull ropes are wound around the two shafts, and the fixing ring is fixedly connected to the pull ropes. The camera is fixedly connected to the fixing ring. An adjustment component is provided on the first housing. This invention allows the two pull ropes to be connected together below the bridge, and the movement of the pull ropes controls the movement of the camera, enabling the camera to detect cracks at the bottom of the bridge and determine their location. However, because the trolleys have wheels on their underside, this invention does not use a limiting mechanism to restrict wheel movement during detection. If the wheels move, the detection effect is reduced, leading to a longer detection time for the workers. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a civil engineering road and bridge surveying device, which has advantages such as stable placement of the surveying device. It solves the problem that because the trailer has wheels on its lower surface, this utility model does not use a limiting mechanism to limit the wheels during surveying.

The worm wheel and the worm gear are meshed together. A movable plate is threaded to the outer surface of the lead screw. A connecting block is fixed to the lower surface of the movable plate. The lower surface of the connecting block penetrates the fixed cavity and extends to the lower side of the road and bridge surveying device body and is fixed with a support plate.

[0007] Furthermore, the number of the omnidirectional wheels is four, and the four omnidirectional wheels are evenly distributed on the lower surface of the road and bridge surveying device body.

[0008] Furthermore, a push handle is fixed to the top of the front of the road and bridge surveying device body, and an anti-slip sleeve is fixed to the middle of the outer surface of the push handle. The anti-slip sleeve is a rubber sleeve.

Threaded rods are fixed to both ends of the dual-axis motor. A threaded sleeve is threaded to the outer surface of the threaded rod. A clamping plate with one end penetrating through and extending to the upper side of the rotating plate is fixed to the upper surface of the threaded sleeve.

[0013] Furthermore, the output shaft of the rotating motor is fixed to the rotating shaft, and the other end of the threaded rod is rotatably connected to the inner side wall of the rotating plate through a bearing. A guide hole is provided on the upper surface of the rotating plate, a slider is fixed on the lower surface of the threaded sleeve, and slide bars are fixed on both the left and right ends of the inner bottom wall of the rotating plate. The slider moves horizontally in the inner cavity of the slide bar.

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] Please see Figure 1This embodiment of a civil engineering road and bridge surveying device includes a road and bridge surveying device body 1. Universal wheels 2 are fixed at both ends of the lower surface of the road and bridge surveying device body 1. A limiting mechanism 3 for limiting the universal wheels 2 is provided at the bottom of the inner cavity of the road and bridge surveying device body 1. A camera 4 is provided on the upper side of the road and bridge surveying device body 1. An adjustment mechanism 5 is provided in the middle of the upper surface of the road and bridge surveying device body 1.

[0025] In this embodiment, there are four casters 2. The four casters 2 are evenly distributed on the lower surface of the road and bridge surveying device body 1. The four evenly distributed casters 2 provide good mobility and facilitate the movement of the surveying device. A push handle is fixed to the top of the front of the road and bridge surveying device body 1. An anti-slip sleeve is fixed to the middle of the outer surface of the push handle. The anti-slip sleeve is a rubber sleeve, which increases the friction with the worker's hands and prevents the worker's hands from slipping.

[0026] Please see Figures 2 to 4 To adapt to different usage conditions of the road and bridge surveying device body 1, the limiting mechanism 3 in this embodiment includes a fixed cavity 301 opened at the bottom of the inner cavity of the road and bridge surveying device body 1. A drive motor 302 is fixed to the left end of the bottom wall of the fixed cavity 301. A worm gear 303 is fixed to the output shaft of the drive motor 302. A lead screw 304 is rotatably connected to the left end between the top wall and the bottom wall of the fixed cavity 301 via a bearing. A limiting rod 305 is fixed to the right end between the top wall and the bottom wall of the fixed cavity 301. A worm wheel 306 is fixed to the top of the outer surface of the lead screw 304. The road and bridge surveying device body 1 can be moved to the target detection point by the caster wheel 2. Then, the drive motor 302 is started. The output shaft of the drive motor 302 rotates, which drives the worm gear 303 to rotate. The rotation of the worm gear 303 causes the worm wheel 306, which is meshed with it, to rotate. The rotation of the worm wheel 306 causes the lead screw 304 fixed in its inner cavity to rotate.

[0027] The worm gear 306 and the worm 303 are meshed together. The outer surface of the lead screw 304 is threaded with a movable plate 307. The lower surface of the movable plate 307 is fixed with a connecting block 308. The lower surface of the connecting block 308 passes through the fixed cavity 301 and extends to the lower side of the road and bridge surveying device body 1, and a support plate 309 is fixed thereon. The rotation of the lead screw 304 causes the movable plate 307 threaded on its surface to drive the connecting block 308 and the support plate 309 to move downward. The movement of the support plate 309 allows it to contact the ground. At this time, the road and bridge surveying device body 1 can be supported by the support plate 309 until the support plate 309 moves to lift the caster 2, so that preparatory work before surveying can be carried out.

[0028] In this embodiment, the right end of the worm gear 303 is rotatably connected to the side opposite to the right side wall of the inner cavity of the fixed cavity 301 via a bearing, the limiting rod 305 is slidably connected to the movable plate 307, and a through hole is provided in the middle of the bottom wall of the inner cavity of the fixed cavity 301, the size of the inner cavity of the through hole being adapted to the size of the connecting block 308.

[0029] Among them, the support plate 309 and the connecting block 308 are fixed with diagonal bracing plates on opposite sides. The support plate 309 is a rubber plate. The rubber plate can increase the friction between the support plate and the road and bridge ground, and improve the stability of the road and bridge surveying device body 1 during the survey.

[0030] It should be noted that the limiting mechanism 3 ensures the stability of the equipment during operation and prevents accidental movement. Through the drive motor 302, the worm gear 303-worm wheel 306 transmission system and the lead screw 304-moving plate 307 connection, the support plate 309 can be automatically raised and lowered to adapt to different usage conditions.

[0031] Please see Figure 5 To allow the camera 4 to be removed and stored separately when not in use, the adjustment mechanism 5 in this embodiment includes a receiving groove 501 located in the middle of the upper surface of the road and bridge surveying device body 1. A rotating motor 502 is fixed inside the cavity of the receiving groove 501. A rotating shaft 503 is rotatably connected to the middle of the upper surface of the road and bridge surveying device body 1 via a bearing. A rotating plate 504 is fixed to the upper surface of the rotating shaft 503. When the rotating motor 502 is started, the output shaft of the rotating motor 502 rotates, driving the rotating shaft 503 to rotate. The rotation of the rotating shaft 503 causes the rotating plate 504 fixed to its upper surface to rotate, thereby adjusting the angle of the camera 4 to facilitate surveying at different angles. The middle of the inner bottom wall of the rotating plate 504... A dual-axis motor 505 is fixed, and threaded rods 506 are fixed to both ends of the dual-axis motor 505. The camera 4 is placed on the upper surface of the rotating plate 504, and then the dual-axis motor 505 is started. The output shaft of the dual-axis motor 505 rotates, driving the two threaded rods 506 to rotate. The outer surface of the threaded rod 506 is threadedly connected to the sleeve 507. The upper surface of the sleeve 507 is fixed with a clamping plate 508 that extends through and to the upper side of the rotating plate 504. The rotation of the threaded rod 506 causes the sleeve 507 threadedly connected to its surface to move relative to each other. The relative movement of the two sleeves 507 can cause the two clamping plates 508 to move relative to each other, thereby clamping the two sides of the camera 4 and fixing the camera 4.

[0032] In this embodiment, the output shaft of the rotating motor 502 is fixed to the rotating shaft 503, and the other end of the threaded rod 506 is rotatably connected to the inner side wall of the rotating plate 504 through a bearing. A guide hole is provided on the upper surface of the rotating plate 504, and a slider is fixed on the lower surface of the threaded sleeve 507. Slide bars are fixed on both the left and right ends of the inner bottom wall of the rotating plate 504. The slider moves horizontally in the inner cavity of the slide bar, which can limit the movement of the threaded sleeve 507 so that it can only move in a straight line.

[0033] In addition, the output shafts at both ends of the dual-axis motor 505 rotate in the same direction, and the threads on the surfaces of the two threaded rods 506 are opposite in structure.

[0034] It should be noted that the multi-angle shooting function ensures accurate recording of roads and bridges from multiple angles, providing high-quality basic data for subsequent data analysis. Furthermore, when not in use, camera 4 can be removed and stored separately to avoid damage to camera 4 and extend the service life of the equipment.

[0035] The working principle of the above embodiments is as follows:

[0036] (1) When surveying roads and bridges, the road and bridge surveying device body 1 can be moved to the target detection point by using the casters 2. Then, the drive motor 302 is started. The output shaft of the drive motor 302 rotates and drives the worm 303 to rotate. The rotation of the worm 303 causes the worm wheel 306 meshing with it to rotate. The rotation of the worm wheel 306 causes the lead screw 304 fixed in its inner cavity to rotate. The rotation of the lead screw 304 causes the movable plate 307 threaded on its surface to drive the connecting block 308 and the support plate 309 to move downward. The movement of the support plate 309 can make it contact the ground. At this time, the road and bridge surveying device body 1 can be supported by the support plate 309 until the support plate 309 moves to lift the casters 2, so that the preparatory work before the survey can be carried out.

[0037] (2) Then place the camera 4 on the upper surface of the rotating plate 504, and start the dual-axis motor 505. The output shaft of the dual-axis motor 505 rotates and drives the two threaded rods 506 to rotate. The rotation of the threaded rods 506 causes the threaded sleeves 507 connected to its surface to move relative to each other. The relative movement of the two threaded sleeves 507 can cause the two clamping plates 508 to move relative to each other, thereby clamping the two sides of the camera 4 and fixing the camera 4. Then start the rotating motor 502. The output shaft of the rotating motor 502 rotates and drives the rotating shaft 503 to rotate. The rotation of the rotating shaft 503 causes the rotating plate 504 fixed on its upper surface to rotate, thereby adjusting the angle of the camera 4 to facilitate surveying at different angles.

[0038] It should be noted that, in this document, relational terms such as "first" and "second" are used only to distinguish one entity or operation from another, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Furthermore, the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such a process, method, article, or apparatus. Without further limitations, an element defined by the phrase "comprising one..." does not exclude the presence of other identical elements in the process, method, article, or apparatus that includes said element.
