Description

Outdoor isolating switch maintenance bracket

technical field

The utility model relates to isolating switch equipment, in particular to an outdoor isolating switch maintenance bracket.

Background technique

The power system uses a large number of outdoor isolating switchgear. When overhauling outdoor isolating switches, it is usually necessary to use a crane to disassemble and assemble the outdoor isolating switches. However, the use of cranes in construction has problems such as large power outage range, high cost, and limited construction conditions, and it is difficult to be widely used. At present, when the outdoor isolating switch is overhauled, the outdoor isolating switch is usually disassembled by using a puller device. The existing problems are: high work intensity and low efficiency. At the same time, the staff's safety belt is hung on the post insulator and The phenomenon of hanging low and using high makes the safety of maintenance personnel not guaranteed, and there is a serious potential safety hazard.

Contents of the invention

The purpose of the utility model is to overcome the deficiencies of the prior art and provide an outdoor isolating switch maintenance bracket with reasonable structural design, low working intensity, high efficiency and cost saving.

The utility model solves its technical problem and realizes by taking the following technical solutions:

An outdoor isolating switch maintenance bracket, including a frame structure composed of front and rear crossbars, left and right crossbars, and two pairs of longitudinal bars. The front and rear crossbars are vertically and symmetrically installed on the upper ends of the front and rear sides of the two pairs of longitudinal bars, and the left and right crossbars are vertical and symmetrical. Installed on the upper ends of the left and right sides of the two pairs of vertical rods, and a pair of support beams are respectively installed at the lower ends of the left and right vertical rods, and each pair of support beams is installed together with the cross beam of the outdoor isolating switch.

Moreover, each pair of support beams includes a lower support beam and an upper support beam. Both the upper support beam and the lower support beam are installed together with the beam of the outdoor isolating switch through two pairs of U-shaped bolts and connecting plates.

Moreover, the support beam is made of channel steel.

Moreover, the installation method of the front and rear cross bars and the longitudinal bars is a bolt installation method, and the installation method of the left and right cross bars and longitudinal bars is a bolt installation method.

Moreover, the two pairs of longitudinal bars are provided with multiple pairs of installation holes for adjusting the longitudinal installation positions of the front and rear cross bars.

Moreover, the longitudinal rod is a metal pipe or an insulating pipe.

Advantage and positive effect of the present utility model are:

1. The maintenance bracket adopts the front and rear cross bars, the left and right cross bars and two pairs of longitudinal bars to form a frame structure, and the bracket beams at the lower ends of the left and right longitudinal bars are installed together with the beams of the outdoor isolating switch. It is suitable for the hoisting operation of the isolating switch and the suspension of the safety belt of the maintenance personnel, avoiding the problems that the lifting device and the safety belt hanging point are located on the same side and the safety belt is hung low and high, so that the safety of the maintenance personnel is guaranteed.

2. This maintenance bracket avoids the problems of large power outage range, high cost, and limited construction conditions caused by the disassembly and assembly of the outdoor isolating switch by a crane, reduces work intensity, improves work efficiency, and saves costs.

3. This maintenance bracket is provided with multiple pairs of mounting holes on the two pairs of longitudinal bars that can adjust the longitudinal installation position of the front and rear cross bars. The front and rear cross bars can be installed at different positions on the longitudinal bars, and can be applied to outdoor isolation of various heights. switch, expanding its scope of application.

4. The longitudinal rod of the maintenance bracket uses an insulating tube to solve the problem of the small distance between the site and the charged, and further ensures the safety of the maintenance personnel.

5. The design of the utility model is reasonable. By lifting the outdoor isolating switch and hanging the safety belt of the maintenance personnel on the front and rear cross bars respectively, the work intensity is reduced, the work efficiency is improved, and the safety of the maintenance personnel is ensured.

Detailed ways

Below in conjunction with accompanying drawing, the utility model embodiment is described in further detail:

An outdoor isolating switch maintenance support, as shown in Figure 1 and Figure 2, is a frame structure composed of front and rear cross bars 2, left and right cross bars 3, and two pairs of longitudinal bars 1, and the front and rear cross bars, left and right cross bars are all made of metal tubes As a result, the two pairs of longitudinal rods can be made of metal pipes or insulating pipes. The upper ends of the two pairs of longitudinal bars are provided with multiple pairs of mounting holes 4 for adjusting the longitudinal installation positions of the front and rear cross bars. Bolt installation method; the left and right horizontal bars are vertically and symmetrically installed on the upper ends of the left and right sides of the two pairs of longitudinal bars, and the installation method is the bolt installation method. A pair of support beams are respectively installed at the lower ends of the left and right vertical rods, each pair of support beams includes an upper support beam 5 and a lower support beam 80%. The upper support beam and the lower support beam are both made of channel steel. The bottoms of the two longitudinal bars are fixed together, and the fixing method is welding. The two upper support beams are respectively set on the left and right longitudinal bars, and between each pair of upper support beams and lower support beams between the left and right longitudinal bars. Both are installed with two pairs of U-shaped bolts 7 and connecting plates 6, and are installed together with the beam 9 of the outdoor isolating switch through the two pairs of U-shaped bolts 7 and the connecting plates 6.

The method of using the maintenance bracket of the outdoor isolating switch is as follows: first, install the upper bracket beam and the lower bracket beam with the beam of the outdoor isolating switch, and then the maintenance personnel hang the safety belt on the front cross bar or the rear cross bar, and at the same time, hoist the The pulley is suspended on the rear cross bar or the front cross bar to carry out the lifting operation, and finally complete the maintenance work of the outdoor isolating switch.

It should be emphasized that the embodiments described in the utility model are illustrative rather than restrictive, so the utility model is not limited to the embodiments described in the specific implementation, anyone skilled in the art according to the utility model Other implementations derived from the technical solution also belong to the protection scope of the present utility model.
