Description

Technical Field

[0001] The invention relates to the technical field of cable bridges, and in particular to a stepped combined cable bridge which is easy to install and adjust. Background Art

[0002] Cable trays are divided into trough type, tray type, ladder type, grid type and other structures, and are composed of brackets, brackets and installation accessories. The cable trays in buildings can be erected independently or laid on various buildings (structures) and pipe gallery brackets. They should have the characteristics of simple structure, beautiful shape, flexible configuration and convenient maintenance. The ladder type cable tray is improved and designed based on relevant domestic and foreign data. It has the advantages of light weight, low cost, unique shape, good heat dissipation and ventilation. It is suitable for the laying of cables with larger diameters and high and low voltage power cables.

[0003] When installing the existing stepped combined cable tray, workers are required to climb up with ladders, and when installing screws, they need to constantly go up and down to adjust the position of the ladder. The process is cumbersome and creates a heavy workload for the workers. Long-term work at high altitudes with the head raised will cause dizziness and other physiological conditions for the workers, making the safety of the workers in the process not guaranteed. At the same time, when the existing cable trays are overlapped, the upper cable tray is often placed directly on the lower cable tray, which makes the heat dissipation effect worse, and the placement method is very unstable and prone to shaking. In this regard, we propose a stepped combined cable tray that is easy to install and adjust. Summary of the invention

[0004] The technical problem to be solved by the present invention is to overcome the shortcomings of the prior art and provide a stepped combined cable tray that is easy to install and adjust, which can solve the inconvenience of workers having to climb high during installation and enable the tray to work better.

[0005] The technical solution of the present invention to solve the above technical problems is: to provide a stepped combined cable bridge that is easy to install and adjust, including a vertical rod fixed on the wall and a horizontal plate arranged just below the vertical rod, both ends of the horizontal plate are fixedly connected with a connecting rope, the connecting rope passes through the vertical rod and extends into the wall, a gathering block is also fixed in the wall, and the two connecting ropes are gathered and hung down by the gathering block, a bearing plate is provided on the horizontal plate through a lifting mechanism, and two layers of bridge frames are arranged on the bearing plate, two fixing blocks are fixed on the lower wall of the bridge frame, and the fixing block of the bottom wall of the lower bridge frame is placed on the bearing plate, a plurality of rotating cavities are provided on the inner wall of the vertical rod, and a plurality of rotating cavities are rotatably provided with rotating plates, a plurality of limiting plates are also fixed on the inner wall of the vertical rod, and the limiting plate is arranged at the lower end of the rotating cavity, and fixing plates are also fixed at both ends of the horizontal plate, the fixing plates are vertically arranged and fit with the vertical rod, and the fixing plates and the vertical rod are fixedly connected by screw threads.

[0006] Further limiting technical solutions of the present invention:

[0007] Further: the lifting mechanism includes a first gear rotatably set in a horizontal plate, a rotating cylinder is fixedly provided on the lower wall of the first gear, second gears meshing with each other are rotatably provided on both sides of the first gear, threaded rods are fixedly provided on the two second gears, and the thread directions of the two threaded rods are set in opposite directions, a corresponding threaded cylinder is fixedly provided on the lower wall of the horizontal plate, and a nut is fixedly provided on the lower end of the threaded cylinder, the nut and the threaded rod are matched, the threaded rod passes through the nut and the threaded cylinder, and the threaded rod and the nut are arranged together.

[0008] The beneficial effect of the above further scheme is that when the rotating drum is rotated, the first gear can be rotated, thereby driving the two second gears to rotate, so that the two threaded rods in opposite directions rotate synchronously and push the threaded drum to move upward, thereby lifting the load plate and the bridge placed on the load plate. The process is simple and does not require manual transportation of the bridge. It also avoids long-term high-altitude work, ensures the safety of workers, and greatly improves work efficiency.

[0009] Further: a rotating wheel is fixedly provided at the connection point between the tightening block and the connecting rope, and the connecting rope is made of nylon rope.

[0010] The beneficial effect of the above further scheme is: preventing the connection rope from having a large friction when passing through the gathering block, thereby preventing the connection rope from breaking due to long-term use, thereby ensuring that the device can work normally and avoiding safety problems.

[0011] Further: a rotating disk is fixedly provided at the lower end of the rotating drum, the side wall of the rotating disk is arranged in an arc shape, and a rubber anti-slip sleeve is sleeved on the side wall of the rotating disk.

[0012] The beneficial effect of the above further scheme is that it is convenient for the staff to rotate the rotating drum by rotating the rotating disk, and at the same time prevents the slipping phenomenon that may occur when rotating the rotating disk, thereby improving the work efficiency.

[0013] Further: a fixing rod is fixedly provided at the lower end of the two threaded tubes on one side away from the second gear, and a telescopic rod is fixedly provided at the other end of the fixing rod. The telescopic rod is vertically arranged, and the lower end of the telescopic rod is embedded in the horizontal plate.

[0014] The beneficial effect of the above further solution is that it effectively prevents the threaded barrel from rotating when it rises or falls, thereby ensuring the normal rising and falling process of the bearing plate.

[0015] Furthermore: the vertical rod and the plurality of limit plates are all integrally formed, and the surface of the limit plates is rough.

[0016] The beneficial effect of the above further solution is that the stability of the structure is improved, and the bridge frame is prevented from being placed on the rotating plate for a long time, thereby preventing the limit plate from being pressed and detached from the vertical rod.

[0017] Further: the rotating plate is made of metal material, and the surface of the rotating plate is coated with protective paint.

[0018] The beneficial effect of the above further solution is to prevent possible oxidation and rusting on the surface of the rotating plate, thereby increasing the service life of the structure.

[0019] The beneficial effect of the present invention is that when the device is in use, the connecting rope can be loosened first, so that the horizontal plate falls to the ground under the action of gravity, and then the bridge frame to be fixed is placed on the bearing plate on the horizontal plate, and then the connecting rope is pulled to make the bridge frame rise until the lower end of the vertical rod and the two ends of the horizontal plate are against each other. At this time, the fixing plate and the vertical rod are screwed together to prevent them from tilting or swinging. Then, the jacking mechanism is set to jack up the bearing plate connected to the bridge frame, and when the lower end of the upper bridge frame passes through the upper rotating plate, the reverse rotation is performed. The lifting mechanism is moved to make the bridge start to descend. Under the action of the limit plate, the rotating plate can only be rotated to a horizontal position, so that the lower end of the upper bridge is placed on the upper rotating plate when passing through the rotating plate. The lifting mechanism is continued to be rotated, and the lower bridge is also placed on the lower rotating plate when passing through the rotating plate, so that there is a large gap between the two layers of bridge, which is convenient for efficient heat dissipation and prevents possible safety hazards of the bridge from being attached. At the same time, the whole installation process does not require the staff to climb, and the installation limit and fixation of the bridge can be carried out on the ground.
