Description

10kV central cabinet circuit breaker maintenance handcart

technical field

The utility model belongs to the technical field of maintenance tools in power system substations, and in particular relates to a handcart for maintenance of circuit breakers in 10kV central cabinets.

Background technique

Due to the advantages of compact structure and small footprint, 10kV central circuit breakers are widely used in power systems. When the 10kV mid-mounted circuit breaker needs to be overhauled, it is dragged to the maintenance trolley through the track, and then the maintenance trolley is pulled out of the cabinet to carry out the maintenance test. However, in the field work, it is found that due to the difference in pressure change, voltage change, and circuit breaker switch cabinet height and width, it is often necessary to configure at least three maintenance handcarts on site to meet the work needs. If there are different manufacturers, more maintenance handcarts are equipped. . In addition, the existing maintenance trolley has a high clearance from the ground. When it is necessary to move the circuit breaker away from the maintenance trolley, at least five people are required, and there are great safety hazards.

Contents of the invention

The purpose of this utility model is to provide a 10kV central cabinet circuit breaker maintenance handcart, the handcart has a lifting function to meet the use of switch cabinets with different heights and the same width, reduce the number of maintenance handcarts configured on site, and can The circuit breaker moves smoothly to the ground for easy circuit breaker replacement.

The technical solution of the utility model is: the handcart includes a tow bar, a bottom plate, a pulley, a hydraulic jack, a positioning pin, an auxiliary support, an upper panel, an upper screw column, an adjusting screw, a lower screw column, a lower panel, a shaft, and a slope plate And fixed feet, the tow rod is installed on one side of the bottom plate, the pulley is installed on the bottom surface of the bottom plate, the hydraulic jack is installed on the upper center of the bottom plate, the jack rod of the hydraulic jack is connected to the lower panel, and a group of auxiliary supports is installed on the bottom plate and the lower panel around the hydraulic jack Between them, the positioning pin is set on the auxiliary support, the upper panel is installed on the lower panel through the upper screw column, the adjusting screw and the lower screw column, the slope plate is installed on the side warp shaft of the upper panel, and the fixed feet are installed on the lower part of the slope plate. The overall structure 10kV central cabinet circuit breaker maintenance handcart.

The utility model has the advantages of simple structure and convenient operation. Only two people can realize the displacement of the circuit breaker between the maintenance handcart and the ground, reduce the number of on-site 10kV central cabinet circuit breaker maintenance handcarts, reduce resource consumption, and save labor at the same time , improve work efficiency, and meet the maintenance work needs of 10kV mid-mounted switchgear circuit breakers with the same width and different heights.

Description of drawings

Figure 1 is a schematic structural view of the utility model.

In the figure: 1 tow bar; 2 bottom plate; 3 pulley; 4 hydraulic jack; 5 positioning pin; 6 auxiliary support; 7 upper panel; 8 upper screw post; 9 adjustment screw; 10 lower screw post; ; 13 slope board; 14 fixed feet.

Detailed ways

As shown in Figure 1, the handcart includes a tow bar 1, a bottom plate 2, a pulley 3, a hydraulic jack 4, a positioning pin 5, an auxiliary support 6, an upper panel 7, an upper screw column 8, an adjustment screw 9, a lower screw column 10, Lower panel 11, shaft 12, slope plate 13 and fixed foot 14, tow bar 1 is installed on one side of base plate 2, pulley 3 is installed on the bottom surface of base plate 2, hydraulic jack 4 is installed in the upper center of base plate 2, and the ejector rod of hydraulic jack 4 The upper part is connected with the lower panel 11, and a group of auxiliary supports 6 are installed between the base plate 2 and the lower panel 11 around the hydraulic jack 4. The positioning pin 5 is set on the auxiliary support 6, and the upper screw column 8, the adjustment screw 9, The upper panel 7 is installed on the lower screw column 10, and the slope plate 13 is installed on the side warp axis 12 of the upper panel 7, and the fixed foot 14 is installed on the bottom of the slope plate 13, which constitutes a 10kV central cabinet circuit breaker maintenance handcart as a whole.

When it needs to be used between circuit breaker cabinets with different heights and the same width, you only need to pull the tow bar 1 to drag the 10kV central cabinet circuit breaker maintenance handcart to the designated position, and use the hydraulic jack 4 to lift the upper panel 7 and the lower panel. 11 is raised, and when the auxiliary support 6 is raised to the designated position at the same time, the positioning pin 5 is pushed in, and at this time, the height of the upper panel 7 is roughly adjusted; , to realize the fine adjustment of the height of the upper panel 7; when the circuit breaker needs to be shifted between the maintenance trolley and the ground, the energy of the hydraulic jack 4 is released, the ramp plate 13 is lifted around the shaft 12 and the fixed feet 14 are opened, Just push the breaker down along the ramp.
