Disclosure of Invention

The technical problem to be solved by the invention is that when the cable in the bridge is required to be operated, because the cable is positioned at the bottom or the corner of the bridge, a worker needs to pull out the cable outwards for operation during operation, and the number of the cables pulled out under the action of manpower is limited, so that the operation of the cable is complicated and inconvenient.

In order to solve the technical problems, the invention provides a cable bridge convenient to maintain, which comprises a tank body and a cover plate, wherein the bottom of the tank body is divided into a wiring groove and an operating groove along the width direction, a supporting plate used for containing cables is arranged at the bottom of the wiring groove, a first support and a second support are respectively hinged on two sides of the lower end of the supporting plate in the length direction in a sliding manner, the first support and the second support are arranged in a crossed manner, a rotating shaft which is simultaneously inserted into the first support and the second support is arranged at the position of the crossed point of the first support and the second support, the end part, deviating from the supporting plate, of the first support and the second support slides on the inner wall of the wiring groove along the length direction of the supporting plate, a rack arranged along the length direction of the tank body is fixed at the bottom of the first support, a driving device used for pushing the first support is arranged at one end, close, The ratchet wheel is coaxial with the driven gear in the operation groove, the rotating column is coaxially connected between the driven gear and the ratchet wheel, and the pawl is rotatably connected to the inner wall of the operation groove and used for preventing the ratchet wheel from reversing.

The technical effects are as follows: when the cable routing device is normally used, the supporting plate is positioned at the bottom of the cable routing groove, all cables are placed on the supporting plate, and normal wiring is carried out; when the cable needs to be operated or the inside of the tank body needs to be cleaned, firstly, the ratchet wheel rotates, the rotation of the ratchet wheel drives the rotating column to rotate along with the rotating column, the rotation of the rotating column drives the driven gear to rotate in the same direction, the driven gear is meshed with the rack, so the rotation of the driven gear drives the rack to move in the direction of the tank body, the rack also drives the lower end of the first bracket fixed with the rack to slide in the direction of the tank body, the first bracket and the second bracket are arranged in a crossed manner, and the position of the crossed point of the first bracket and the second bracket is provided with the rotating shaft, so when the lower end of the first bracket moves in the tank body, namely the lower end of the first bracket and the lower end of the second bracket are close to each other, the upper end of the first bracket is also close to the upper end of the second bracket, so the upper ends of the first bracket and the second bracket both move upwards, the whole supporting plate is driven to move upwards, so that the cable on the supporting plate is supported out of the groove body; when the supporting plate moves upwards to a certain height, the ratchet wheel stops rotating, and due to the arrangement of the compression spring, the pawl is reset all the time, so that the pawl is automatically embedded into the ratchet wheel, the ratchet wheel cannot rotate in the opposite direction, the supporting plate cannot fall back when being lifted, the cable can be kept stable, and the cable can be conveniently operated by a worker; after the operation of the cable is completed, the pawl is rotated, so that the pawl and the ratchet wheel are separated from each other, the supporting plate is reset into the groove body due to the fact that the supporting plate automatically moves downwards due to the weight of the supporting plate and the cable, the convenience of the vertical sliding of the supporting plate is greatly improved, and the efficiency of workers is improved.

The technical scheme of the invention is further defined as follows: the operating groove is vertically provided with a driving rod vertically sleeved on the rotating column.

Furthermore, the driven gear is attached to the upper portion of the rack.

In the cable bridge convenient to maintain, the diameter of the moving gear is smaller than that of the ratchet wheel.

In the cable bridge convenient to maintain, the pawl is provided with the compression spring for driving the pawl to reset.

In the cable bridge convenient to maintain, the width of the operation groove is set to be smaller than that of the cabling groove.

The invention has the beneficial effects that:

(1) according to the ratchet wheel driving device, when the ratchet wheel needs to be rotated, the driving rod is firstly sleeved on the rotating column and then rotated, when the ratchet wheel rotates to a certain angle, the driving rod is separated from the rotating column and reset after being separated, and then the driving rod is sleeved on the rotating column, so that a worker can drive the ratchet wheel to rotate only by rotating the driving rod, the vertical driving rod is more convenient for the worker to apply force to the vertical driving rod, the operability of the driving device is improved, the driven gear is arranged above the rack, so that the rack is driven to rotate inwards when the driving rod rotates outwards, and the operating space of the worker is larger when the driving rod rotates outwards, and the working efficiency of the operator is also increased;

(2) according to the invention, the diameter of the driven gear is smaller than that of the ratchet wheel, so that when the ratchet wheel rotates, the driven gear drives the rack to slowly slide, and the whole supporting plate is slowly lifted out of the groove body, so that the displacement of the supporting plate is safer and more stable, the cable cannot be damaged due to too fast lifting, and the rationality and safety of the whole bridge are enhanced;

(3) according to the invention, the arrangement of the compression spring enables the pawl to automatically restore to the original position, namely, the pawl is prevented from rotating to the opposite direction, so that a worker does not need to manually embed the pawl into the ratchet wheel when the supporting plate rises to a proper height, the driving device is more automatic, the convenience is greatly improved, the width of the operating groove is set to be smaller than that of the wiring groove, the space of the wiring groove is larger, the area of the supporting plate which can be arranged is larger, more cables can be placed, and the practicability of the bridge frame is improved.
