Description

A maintenance platform for tubular busbar post insulators

technical field

The invention relates to an auxiliary device for maintenance of electric equipment.

Background technique

Aiming at the actual construction problems in the maintenance work of 220KV tubular busbar post insulators: the tubular busbar is located on the gantry frame with a high height from the ground, there is not enough room for maintenance personnel to operate, and there is no reliable safety protection; the maintenance personnel disassemble the busbar and porcelain bottles There are no safe climbing devices and protective measures for fasteners; there is no small lifting device with sufficient flexibility when disassembling the busbar, and a large crane has to be called. The use of the large crane is limited to the site space, and a lot of maintenance funds are wasted. Therefore, it has become a top priority to develop a set of maintenance equipment for tubular female post insulators to solve the above practical problems.

Contents of the invention

In view of this, the purpose of the present invention is to provide a high-altitude maintenance platform that can provide sufficient safe space for maintenance personnel and meet the construction lifting conditions.

In order to solve the above technical problems, the technical solution provided by the present invention is to provide a maintenance platform for tubular busbar post insulators, including a large low-level platform, a guardrail frame is installed around the large low-position platform, and a small high-level platform and a miniature crane are installed inside the guardrail frame. The low platform is secured to the portal frame with stud clamps and U-rings.

The low-position large platform is stabilized by tie bars.

The miniature crane includes a base, and the base is composed of upper and lower base plates, and the upper and lower base plates are fixed on the portal frame by stud bolt clamps.

A door opening is arranged on the large low platform, and the door opening is connected to one end of the single ladder, and the other end of the single ladder is erected on the bottom surface.

The high-position small platform is composed of a support seat and a flat plate at the top of the support seat, and the lower end of the support seat is fixed on the portal frame through a U-shaped ring.

Beneficially, the maintenance platform for tubular busbar post insulators of the present invention adopts a large number of dismantled structures, and provides a flexible and optimal combination of a large low-position platform, a small high-position platform, and a miniature crane for the purpose of safety, convenience and speed. Greatly improved the maintenance conditions of tubular busbar post insulators, and saved a lot of maintenance costs on the basis of ensuring construction safety and construction progress.

detailed description

The following will be described in conjunction with the accompanying drawings and specific embodiments.

See Figures 1 to 3. The maintenance platform for tubular busbar post insulators described in this embodiment is installed on a portal frame. The maintenance platform includes a large low platform 1, a small high platform 2 and a miniature crane 3. More practical needs, the size of the large low platform 1 and the size and height of the small high platform can be selected to suit the size. The low large platform 1 is on the same plane as the cross bar of the portal frame, and the portal frame cross bar also serves as a part of the low large platform 1 during use. The large platform 1 at the low position, the small platform 2 at the high position and the miniature crane 3 can all be fixed on the portal frame.

The bottom of the large low platform 1 is spliced by a plurality of insulating base plates, and each base plate is erected on the support rod at the bottom of the low large platform 1. It is further stabilized by the tie bars 14. One end of the tie bar 14 is connected with the above-mentioned support rod, and the other end is connected with the lower part of the portal frame cross bar.

A guardrail frame 11 is installed around the low large platform 1, and the cross bar and the vertical bar of the guardrail frame 11 are insulating rods. Guardrail frame 11 inboards are equipped with high position small platform 2 and miniature crane 3.

Miniature crane 3 is a kind of hoisting machine, is made up of power unit and support two parts. In the maintenance work, the load of 200 kg can meet the lifting requirements. The miniature crane 3 includes a base 31, and the base 31 is composed of two base plates up and down, and the upper and lower base plates are fixed on the portal frame by the stud bolt clamp 12.

For the convenience of the maintenance personnel to board the maintenance platform, a door opening is arranged on the low large platform 1, the door opening is connected to one end of the single ladder 4, and the other end of the single ladder 4 is built on the bottom surface.

The small high platform 2 is composed of a support seat and a flat plate at the top of the support seat. The lower end of the support seat is fixed on the portal frame or directly on the bottom plate of the low large platform 1 through a U-shaped ring 13 .

The above are only preferred implementations of the present invention, and it should be noted that the above preferred implementations should not be regarded as limiting the present invention, and the scope of protection of the present invention should be based on the scope defined in the claims. For those skilled in the art, without departing from the spirit and scope of the present invention, some improvements and modifications can also be made, and these improvements and modifications should also be regarded as the protection scope of the present invention.
