Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of cable monitoring and drag-and-drop in a bridge, and particularly relates to a cable monitoring and drag-and-drop device in a bridge. BACKGROUND

[0002] In power plants, substations, data centers and other power and communication facilities, cable bridges are used as infrastructure to carry dense cables. Due to the large number of cables, layered laying, and the extremely crowded internal space of the bridge, and for safety and protection considerations, the bridge is usually closed or semi-closed. This results in poor internal visibility, forming a typical closed and narrow restricted space. In such a black box environment, daily inspection, state monitoring of cables, and laying of new cables face serious challenges.

[0003] In the prior art, the method of relying on regular manual inspection is limited by the narrow space of the bridge and the blocked view, and cannot fully grasp the layered state of the cables and potential hazards. Although fixed sensors can achieve point monitoring, their coverage is limited, and there are many monitoring blind spots, making it difficult to fully reflect the running state of all cables in the bridge, especially cables located inside or in hidden locations.

[0004] A more serious problem is that during cable laying operations, the construction personnel cannot know the real-time path conditions inside the bridge. This blind operation relying on experience can cause the new cable to be stuck or rubbed with the existing cable or bridge structure. Once stuck, the construction personnel cannot determine the specific location and cause of the sticking, and can only repeatedly try to pull the cable by relying on experience. This not only reduces efficiency, but also risks damaging the insulation layer of the existing cable, damaging the bridge structure, and even causing safety accidents.

[0005] Although there are some movable detection devices or auxiliary laying tools in the prior art, they generally have complex structures, large volumes, and are not convenient to move in narrow bridges, and are difficult to adapt to the complex environment of dense cables. Therefore, there is an urgent need for a multifunctional operation device specially developed for narrow and closed bridge environments, which can monitor the internal state of the bridge and lay new cables without damaging the original cable layout, to solve the problems of inconvenient cable state monitoring, difficult new cable laying, low operation efficiency, and poor safety in the prior art. SUMMARY

[0006] In view of the above or existing problems in the prior art, the present application is proposed.

[0007] Therefore, the purpose of the present application is to provide a cable monitoring and drag-and-drop device in a bridge, which solves the problems of inconvenient cable state monitoring, difficult new cable laying, low operation efficiency, and poor safety in the prior art.

[0008] To solve the above technical problems, the application provides the following technical scheme: a cable monitoring device in a bridge, comprising a monitoring unit for monitoring the real-time condition in the bridge; A moving unit comprising a moving chassis for driving the monitoring unit to move; The moving unit is installed on one side of the bridge, and the moving chassis drives the monitoring unit to move on the bridge.

[0009] As a preferred scheme of the cable monitoring device in the bridge, the moving chassis comprises a base, a connecting seat arranged on one side of the base, and a gear arranged on the base and connected with the connecting seat.

[0010] As a preferred scheme of the cable monitoring device in the bridge, the connecting seat comprises a lower bottom plate sleeved on the gear and an upper cover plate arranged on one side of the lower bottom plate.

[0011] Through the cooperation of the lower bottom plate, the upper cover plate and the gear, the gear drives the upper cover plate to rotate, and the monitoring unit rotates around the vertical shaft, so that the monitoring unit can adjust the observation angle, expand the visual field coverage range, and effectively meet the monitoring requirements of the cable layering and interlacing and complex orientation in the bridge. As a preferred scheme of the cable monitoring device in the bridge, the moving unit further comprises a guide rail for guiding the moving chassis and a traction member penetrating through the base.

[0012] The guide rail provides constraint and guidance for the moving path of the moving unit, and the traction member can provide external traction force to ensure the smooth and directional movement of the device in the narrow bridge, thereby improving the operation reliability. As a preferred scheme of the cable monitoring device in the bridge, the moving unit further comprises a charging unit arranged at one end of the guide rail, and the charging unit is provided with a traction motor at the bottom.

[0013] By arranging the charging unit at one end of the guide rail and providing the traction motor, the automatic return charging and remote traction control of the device are realized, which prolongs the operation time and supports the construction personnel to complete the dragging and placing or recycling operation outside the bridge, thereby significantly improving the automation level and operation convenience of the device.

[0014] As a preferred scheme of the cable monitoring device in the bridge, the monitoring unit comprises a fixing seat arranged on one side of the upper cover plate and a monitoring main body arranged on one side of the fixing seat.

[0015] The monitoring main body is stably connected with the moving unit through the fixing base, the vibration of the driving part is effectively isolated from the monitoring main body, the stability of the monitoring main body during movement is ensured, and clear and stable image data is obtained.

[0016] The application further provides a dragging and placing device applied to the cable monitoring device in the bridge, which comprises a connecting piece arranged on one side of the base, and a dragging and placing unit arranged on one side of the connecting piece. As a preferred scheme of the dragging and placing device applied to the cable monitoring device in the bridge, the dragging and placing unit comprises a clamping seat, a mounting plate arranged on one side of the clamping seat, an extension arm arranged on one side of the mounting plate, and a grabbing unit arranged on one side of the extension arm.

[0017] The combination of the clamping seat, the mounting plate, the extension arm and the grabbing unit enables the device to actively grab and place in the bridge, is suitable for obstacle avoidance and threading in a cable dense area, and solves the problems of easy jamming and low efficiency of traditional blind dragging.

[0018] As a preferred scheme of the dragging and placing device applied to the cable monitoring device in the bridge, the grabbing unit comprises a grabbing motor arranged on one side of the extension arm and a clamping jaw arranged on one side of the grabbing motor.

[0019] The grabbing motor drives the clamping jaw to open and close, realizes clamping and releasing of the cable end, is flexible in operation and quick in response, can adapt to the dragging and placing requirements of cables with different diameters, avoids damage to the cable sheath caused by hard dragging, and improves the safety and compatibility of operation.

[0020] As a preferred scheme of the dragging and placing device applied to the cable monitoring device in the bridge, a clamping groove for movement on the guide rail is arranged on the clamping seat.

[0021] Through cooperation of the clamping groove and the guide rail, it is ensured that the dragging and placing device can move synchronously with the monitoring device on the same path, and the spatial consistency of the operation field of view and operation action is ensured.

[0022] Advantages of the scheme: The monitoring device can monitor the inside of the closed and narrow bridge through the movable monitoring unit and the movable chassis, full-coverage monitoring of the cable distribution state and the running environment is realized, the defects of large blind area of a traditional fixed sensor and inability of manual inspection to go deep are overcome, the comprehensiveness and real-time of the cable state in the bridge are provided for the construction personnel.
