Description

Transformer on-load switch lifting inspection device

technical field

The utility model relates to the field of electric power inspection and maintenance, in particular to a lifting inspection device for a transformer on-load switch. the

Background technique

At present, when carrying out transformer inspection and maintenance work in indoor substations, due to the limited indoor space, medium and large lifting equipment cannot enter. Therefore, it takes a lot of manpower and material resources to carry out the inspection of the on-load switch, which not only leads to slow inspection speed and high efficiency. Low, and the safety and stability during the maintenance process cannot be guaranteed. the

Contents of the invention

The purpose of the utility model is to overcome the deficiencies of the prior art, and provide a transformer on-load switch hoisting device with reasonable design, simple operation, stable and safe use, and improved hoisting speed. the

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

A transformer on-load switch lifting inspection device, characterized in that it includes a base, a bearing base, a support vertical bar and a boom cross bar, the bearing base is vertically installed on the upper end of the base, and the support vertical bar is vertically installed on the bearing base Above, the boom cross bar is horizontally installed on the upper end of the supporting vertical bar, and a moving pulley block is installed at the front end of the boom cross bar. the

And, a suspension hook is installed on the described pulley block. the

Moreover, a horizontal sleeve is installed on the upper end of the support vertical bar, and the boom cross bar is coaxially inserted into the horizontal sleeve. A limit pin is installed at the rear end of the boom cross bar, and the length of the limit pin is greater than the outer diameter of the horizontal casing; a blocking piece is installed at the front end of the boom cross bar. the

Moreover, it also includes an obliquely-stayed pipe, the two ends of which are respectively hinged on the support vertical rod and the boom cross-bar. the

Moreover, an installation hole or an installation groove is made on the base. the

Advantage and beneficial effect of the present utility model are:

1. The lifting inspection device is composed of a base, a bearing base, a support vertical bar and a boom cross bar. The movable pulley block is installed on the boom cross bar. Therefore, the device is installed on the transformer and can be lifted by using the movable pulley block and the hook. Check switch, this device is easy to use and can improve work efficiency. the

2. The hoisting device is simple in structure, small in size and light in weight, which solves the problem that the indoor transformer switch cannot be hoisted by hoisting machinery. the

3. The lifting inspection device is a detachable structure, and each part is a single part, which can be replaced, which is convenient for later maintenance. In addition, the detachable structure also improves the convenience of carrying and transportation, which is suitable for going out for work. the

4. Since the support vertical bar is installed on the bearing base, the switch can not only be lifted up and down vertically, but also rotate horizontally with the support vertical bar, which facilitates the work process such as switch test. the

5. The use of this device can reduce the labor intensity of switch lifting and inspection, and improve the stability and safety of the switch lifting and inspection lifting process. the

6. The utility model is a transformer on-load switch lifting inspection device with simple structure, ingenious design, easy manufacture, convenient use and strong practicability. This device achieves the goal of reducing manpower, material resources and financial resources in indoor switch maintenance work , which ensures the safety of the maintenance staff and improves the maintenance efficiency, especially suitable for use in indoor substations. the

Detailed ways

The utility model is described in further detail below through specific examples, the following examples are only descriptive, not limiting, and cannot limit the protection scope of the utility model with this. the

A transformer on-load switch lifting inspection device, including a base 9, a bearing base 8, a support vertical bar 7 and a boom bar 4, and a mounting hole 11 (as shown in Figure 3) or a mounting groove 10 ( As shown in Figure 2), the base is fixed on the transformer through the installation hole or the installation groove. the

The bearing base is vertically installed on the upper end of the base, and the support vertical bar is vertically installed on the bearing base, so the support vertical bar can rotate horizontally. A horizontal sleeve 2 is installed on the upper end of the support vertical bar, and the boom cross bar is coaxially inserted in the horizontal sleeve. In order to prevent the cross bar of the boom from falling off in the horizontal bushing, a stop pin 1 is installed at the rear end of the cross bar of the boom, and the length of the stop pin is greater than the outer diameter of the horizontal bushing. In order to increase the supporting force, a cable-stayed pipe 3 is also designed in the device, and the two ends of the cable-stayed pipe are respectively hinged on the support vertical bar and the boom cross bar. the

A movable pulley block 5 is installed at the front end of the boom cross bar, and a suspension hook 6 is installed on this movable pulley block, and this suspension hook is used for hoisting switch. The front end of the boom cross bar can be equipped with a catch to prevent the movable pulley block from falling off. the

The working principle of the utility model:

When in use, the base of the device is fixed on the transformer, the switch is hoisted by the movable pulley block, the switch is lifted and lowered by the pulley block, the support vertical rod can be rotated by the bearing base, and the switch core can be moved to the outside of the transformer for switch test. The switch contacts and the switch chamber can be cleaned. the
