Description

Secondary cable laying corner bracket

technical field

The utility model relates to a tool for laying secondary cables in substations, in particular to a corner bracket for laying secondary cables.

Background technique

With the rapid development of my country's electric power industry, the construction, expansion and renovation of substations are increasing. In the specific construction process of many large-scale substations, especially substations with a voltage level of 220kV and above, the distance between the control room and primary equipment and other places where secondary cables need to be laid is often relatively far, and many corners must be passed through when laying secondary cables. Traditional The laying method is to invest at least one person in each corner to carry out the laying work, so the workload is heavy and many construction workers are invested. Moreover, some corners have narrow spaces, such as cable trenches, cable interlayers, cable shafts, etc., and it is not easy to quickly lay the secondary cables even if personnel are invested. During the laying process, the cable rubs against the corner of the wall, etc., and it is easy to damage the cable sheath. This seriously affects the speed and quality of laying secondary cables.

Contents of the invention

The purpose of the utility model is to provide a secondary cable laying corner bracket with simple structure and convenient use, which can replace labor at the corner, protect cables, and increase the speed of cable laying.

In order to achieve the above purpose, the technical solution adopted by the utility model is: the secondary cable laying corner bracket includes a base, a slanting rod and a top plate, and the top plate is fixed with the base through four symmetrical slanting rods. It is characterized in that: The middle part of the base is fixed with a column, and a sliding sleeve is set on the column. The upper end of the sliding sleeve passes through the central through hole of the top plate. Horizontal bearings are provided in the middle of the tray, fixed frames are symmetrically provided at both ends of the tray, vertical bearings are provided on the fixed frames, and upper hooks are fixed equidistantly on the inclined rods.

One end of the tray is fixed to the upper pole, the upper end of the pole is fixed to the upper cover through the pin shaft, the other end of the tray is fixed to the upper locking rod through the pin shaft, and the upper end of the locking rod is provided with the outer surface of the cover plate. Hooks with matching ends.

The utility model has the beneficial effects of simple structure and convenient use. It can replace manpower by placing it at the corner during the secondary cable laying process, protect the cable, increase the laying speed, reduce the personnel input for the secondary cable laying work, and reduce labor costs. Strength, improving work efficiency and quality.

Detailed ways

Make the utility model with reference to Fig. 1. The secondary cable laying corner bracket includes a base 1, a slanting rod 2 and a top plate 6, the top plate 6 is fixed with the base 1 through four symmetrical slanting rods 2, and it is characterized in that: the middle part of the base 1 is fixed with a column 3. A sliding sleeve 5 is set on the column 3, the upper end of the sliding sleeve 5 passes through the central through hole of the top plate 6, the upper end of the sliding sleeve 5 is fixed on the upper tray 7, and the lower end of the sliding sleeve 5 is fixed on the upper positioning bar 4, and the The middle part of pallet 7 is provided with horizontal bearing 11, is provided with fixed frame 12 symmetrically at the two ends of pallet 7, is provided with vertical bearing 13 on fixed frame 12, is equidistantly fixed upper hook 14 on inclined bar 2.

One end of the tray 7 is fixed to the upper pole 8, the upper end of the pole 8 is fixed to the upper cover plate 9 through the pin shaft, the other end of the tray 7 is fixed to the upper locking rod 10 through the pin shaft, and the upper end of the locking rod 10 A crotch adapted to the outer end of the cover plate 9 is provided.

When using the utility model, in the process of laying secondary cables, since many substation control rooms are far away from the primary equipment and other places where secondary cables need to be laid, many corners must be passed through during laying, and this cable can be installed and fixed at the corners. In the utility model, the sliding sleeve 5 can be raised and lowered by positioning the cross bar 4. When the sliding sleeve 5 is at a suitable height, the positioning cross bar 4 is rotated so that the two ends of the positioning cross bar 4 are located in the hooks 14 of the corresponding inclined bar 2. Thereby locking the positioning bar 4, preventing the positioning bar 4 from rotating or sliding up and down; open the locking lever 10, lift the cover plate 9, place the cable between the two fixed mounts 12, then cover the cover plate 9, and then use the locking bar 10 to lock it to prevent the cable from coming out. Since the vertical bearing 13 is provided on the fixed frame 12 and the horizontal bearing 11 is provided on the tray 7, the cable is limited in the space between the two vertical bearings 13 and the horizontal bearing 11 , in the process of pulling the cable, the vertical bearing 13 and the horizontal bearing 11 that are in contact with the cable will rotate accordingly. In the process of laying the cable forward, no matter how much a corner is required, the cable laying angle can be effectively reduced. The friction force in the process makes the cable turn smoothly and increases the speed of cable laying, which not only saves manpower, improves the laying efficiency, but also protects the secondary cable and prevents cable wear.
