Description

Technical Field

[0001] The utility model belongs to the technical field of cable maintenance, and particularly relates to an auxiliary device for replacing a cable trough box on a cable tray. Background Art

[0002] A cable trough box is a distribution electrical appliance installed indoors and outdoors, used for installing, protecting, and wiring cables. The cable trough box is convenient to use, can save the cost and time of laying cables, shorten the troubleshooting time, improve the reliability and service life of the cable line, can effectively prevent the wires from being damaged by mechanical damage, chemical corrosion, climate change and other factors, and improve the safety of the wires.

[0003] In current factory production, the air contains acidic gases. Most of the old trough boxes are made of stainless steel or plastic. After years of use, aging and corrosion will cause the plastic and metal materials of the cable trough box to gradually lose strength and stability, resulting in damage and deformation. Cable trough boxes are usually used to protect equipment such as power cables and communication cables. If corrosion causes the insulation layer between the cable and the metal material of the cable tray to be damaged or disappear, a short circuit may occur between the cables, leading to the risk of explosion and fire. At present, manual regular inspections are required in production to replace cable trough boxes with potential safety hazards. During the replacement process, the original trough box needs to be removed, and the cables need to be lifted from the cable tray and then the new trough box is laid underneath. When replacing, all the cables and optical fibers in use in the trough box need to be lifted manually. There are many cables and optical fibers on the cable tray. When lifting, the cables and optical fibers are extremely likely to be damaged by external forces caused by uneven heights, resulting in dangerous accidents. Summary of the Utility Model

[0004] The utility model provides an auxiliary device for replacing a cable trough box on a cable tray to solve the dangerous accidents that occur when lifting cables and optical fibers during manual replacement.

[0005] The technical solution of the utility model is: an auxiliary device for replacing a cable trough box on a cable tray, including a cross beam, columns, and pulleys. There are four cross beams and four columns respectively. The cross beams and columns are connected in sequence to form a rectangular frame body. Pulley is connected to the bottom side of each of the four columns. The pulleys are arranged horizontally and are opposite to each other in pairs.

[0006] As a further improvement of the utility model, the cross beam is fixedly connected to the middle of the column, which is convenient for lifting the cable.

[0007] As a further improvement of the utility model, locking mechanisms are provided on all four pulleys, which can be locked and fixed on the cable trough box.

[0008] The beneficial effects of the present utility model are as follows: A usable frame is formed by the cross beam and the columns. When replacing the cable trough box, the cables can be directly laid on the cross beam, avoiding dangerous accidents caused by manually lifting the cables and optical fibers. Through the different working states of the four horizontal pulleys, the pulleys can be locked to replace the cable trough box with potential safety hazards, or the pulleys can be opened to directly move the entire device on the long-distance bridge, avoiding the waste of manpower caused by repeated disassembly and assembly of the device during replacement. The structure of the present utility model is simple and convenient to use, effectively avoiding dangerous accidents caused by manually lifting the cables and optical fibers, and having strong promotion value. BRIEF DESCRIPTION OF THE DRAWINGS

[0009] Figure 1 It is a schematic three-dimensional structure diagram of the present utility model.

[0010] In the figure: 1 - cross beam, 2 - column, 3 - pulley. DETAILED DESCRIPTION OF THE EMBODIMENTS

[0011] The following further describes the present utility model in detail in conjunction with the drawings and specific embodiments.

[0012] As Figure 1 shown, an auxiliary device for replacing a cable trough box on a bridge, characterized in that it includes a cross beam 1, columns 2 and pulleys 3. There are four cross beams 1 and four columns 2 respectively. The cross beams 1 and the columns 2 are connected in sequence to form a rectangular frame. Pulleys 3 are connected to the bottom sides of the four columns 2. The pulleys 3 are arranged horizontally and are opposite to each other in pairs.

[0013] The cross beam 1 is fixedly connected to the middle of the column 2, which is convenient for lifting the cable.

[0014] All four pulleys 3 are provided with locking mechanisms. The pulleys 3 are used to move on the long bridge composed of cable trough boxes and can be locked and fixed on the cable trough box.

[0015] During use, at the front end of the trough box to be replaced, the entire device is placed under the cable. At this time, the cable is placed on the cross beam 1, and the pulleys 3 on the four columns 2 are placed on the side plates of the original trough box. At this time, the pulleys 3 are stuck on the two sides of the original trough box. The device is pushed by a single person, and the pulleys 3 drive the entire device to slowly move to the place to be replaced. The pulleys 3 are locked to lift the cable in the trough box to be replaced by the cross beam 1, which is convenient for manually removing the trough box and replacing it with a new trough box. For a long-distance bridge that needs to be replaced in multiple places, there is no need to disassemble and assemble the device twice. Just open the pulleys 3 and slide to the place where the trough box needs to be replaced to replace it.
