Description

Hanging basket device for storage tank maintenance

technical field

The utility model relates to a storage tank maintenance device, in particular to a hanging basket device used for storage tank external anticorrosion maintenance.

Background technique

In the inspection and maintenance of storage tanks, external anti-corrosion occupies a large proportion. Previously, scaffolding was used. The steps were cumbersome, it took a long time, and the technical requirements for the erection personnel were high. During the construction, the left and right movement is completed by laying a platform on the scaffold, and there is a possibility of stepping into the air and falling. Moreover, the scaffolding is highly dense and has visual obstacles, which is not conducive to process control and supervision of the appearance quality. In addition to the disadvantages of construction and supervision, the damage of scaffolding to the tank body cannot be ignored. Scaffolding is erected along the outer wall of the tank and is directly welded on the tank. The grinding of the solder joints during disassembly will inevitably cause irreversible damage to the tank. The more times of external corrosion protection, the greater the damage to the tank. There are often many times of external corrosion protection in the process.

In view of the above aspects, it is imperative to develop a kind of equipment that can replace scaffolding. As a suspended manned high-altitude operation equipment, the hanging basket device has strong construction adaptability, large construction height, less construction site occupation, and high construction efficiency. It is high, easy to erect, and requires less labor. It can replace scaffolding for anti-corrosion work outside the storage tank. After using the hanging basket device, it reduces the scaffolding time, shortens the construction period, and saves costs. In addition, the hanging basket device is suspended. Solved the problem of damage to the storage tank.

The existing hanging basket device is designed to be suitable for building construction, and its suspension mechanism needs to occupy a large space, while the storage tank is relatively compact, and the working space is insufficient, so it is not suitable for maintenance of the storage tank.

Utility model content

The main purpose of the utility model is to overcome the defects of the existing hanging basket and provide a hanging basket device with simple structure and reasonable design for storage tank maintenance.

In order to achieve the above purpose, the utility model provides a hanging basket device for storage tank maintenance, including a hanging basket, hanging ropes fixed on the left and right sides of the hanging basket, the bottom end of the hanging rope is connected and fixed with the hanging basket, and the hanging rope A suspension device for connecting with the storage tank is arranged on the top, and the suspension device is a rectangular hook.

Further, reinforcing ribs are respectively provided on both sides of the rectangular hook.

Further, the sling includes a connecting sling and a safety sling.

Further, the front hook wall of the rectangular hook is provided with a first pulley, and a connecting sling is sheathed on the first pulley.

Further, the front hook wall is also provided with a second pulley, and the second pulley is covered with a safety rope.

Further, at least one fixing bolt is provided on the rear hook wall of the rectangular hook.

Further, the connecting rope is provided with an elevator for raising and lowering the hanging basket, and the hanging basket slides up and down along the connecting rope under the action of the elevator.

Further, the safety sling is connected to both sides of the workbench.

Compared with the prior art, the utility model has the following advantages:

The utility model combines the actual dimensions and structural features of the storage tank, innovates and transforms the traditional hanging basket, connects the hanging basket with two self-made rectangular hooks through the hanging rope, and forms a storage tank with light weight, easy movement and small fasteners The special hanging basket for external anti-corrosion is equipped with reinforcing ribs on both sides of the rectangular hook, the second pulley and the first pulley for connecting the safety sling and the sling are set on the front wall of the hook, and a fixed pulley is set on the rear hook wall. The bolt has reasonable structural design, reliable safety performance, low production cost and convenient use.
