Description

A telescopic transfer trolley for switchgear

technical field

The utility model relates to a telescopic transfer trolley for switchgear, which is used for solving the convenience and safety of switchgear operation during maintenance, and belongs to the technical field of power transmission and distribution switchgear.

Background technique

In the power transmission and transformation system, the switchgear is an important part. It realizes the transmission and distribution of electric energy in the power system, and the operation and maintenance of the switchgear is also an important link. The convenience and operability of maintenance are directly Affect the normal, safe and reliable operation of the equipment in the system.

 Because the armored removable AC metal-enclosed switchgear usually adopts a mid-mounted circuit breaker structure, the circuit breaker is moved out of the cabinet by a transfer trolley during maintenance and overhaul. Because the switchgear is usually placed above the channel steel, the channel steel can be placed flat or vertically when designing the foundation, and can be directly above the ground or buried underground, resulting in the distance between the switchgear and the ground. The distance between the equipment and the ground is between 0-100mm. In special cases, when there are steps on the ground, the distance between the switchgear and the ground is greater. Therefore, the circuit breaker transfer trolley must be adjustable in height. The common method is to have 4 screws on the transfer trolley, and use the adjusting nut to change the height of the transfer trolley. However, due to the general weight of the circuit breaker in this solution is 200-400Kg, when the height of the screw adjustment is high, the strength of the transfer trolley is reduced, and at the same time, the stability is poor during the transfer process, which may easily cause the circuit breaker to slip due to improper operation.

Contents of the invention

The purpose of the utility model is to provide a transfer trolley for removing the circuit breaker which can adjust the height arbitrarily and reliably.

In order to achieve the above purpose, the technical solution of this utility model is to provide a telescopic transfer trolley for switchgear, including a supporting plate, and the supporting plate is arranged on the top cover, which is characterized in that: the top cover is arranged on at least two upper columns The top of the upper column is nested in the lower column, the lower column is arranged on the base plate, and casters are arranged at the bottom of the base plate.

Preferably, the supporting plate is arranged on the top cover through a height fine-tuning structure.

Preferably, the height fine-tuning structure includes an adjusting screw, a screw is passed through the adjusting screw, and two ends of the screw are respectively connected with the supporting plate and the top cover.

Preferably, there are at least two height fine-tuning structures, and all the height fine-tuning structures are linked through interlocking pieces.

Preferably, a limiting post is provided on the side of the pallet.

The utility model realizes rough adjustment of the height of the transfer trolley through the nesting structure between the upper column and the lower column, and at the same time ensures the strength of the transfer trolley and the stability of operation.

The utility model has the following advantages: 1. The height adjustment of the transfer trolley is divided into coarse adjustment and fine adjustment, and the height of the trolley meets the needs of various occasions; 2. The strength of the transfer trolley is good, which ensures the stability and safety of the operation.

Fig. 2 is a sectional view along A-A in Fig. 1 .

Detailed ways

In order to make the utility model more obvious and understandable, a preferred embodiment is described in detail as follows in conjunction with the accompanying drawings.

As shown in Figure 1, the utility model provides a telescopic transfer trolley for switchgear, including a supporting plate 1, the supporting plate 1 is arranged on the top cover 6, and two Highly fine-tuned structure. The height fine-tuning structure includes an adjusting screw disk 2, a screw rod 3 is installed in the adjusting screw disk 2, and two ends of the screw rod 3 are respectively connected with the supporting plate 1 and the top cover 6. The interlocking part 5 passes through the two screw rods 3, so that the two screw rods 3 can realize linkage. The interlocking part 5 is used for the mechanical interlocking of the transfer trolley and the switch cabinet to facilitate the circuit breaker to enter and exit the transfer platform. A limit column 4 is provided on the side of the pallet 1, and the limit column 4 is used for the limit of the circuit breaker on the transfer platform.

The top cover 6 is arranged on the tops of the two upper columns 7 . Referring to FIG. 2 , the bottom of the upper column 7 is nested in the lower column 8 , the lower column 8 is set on the bottom plate 9 , and casters 10 are provided at the bottom of the bottom plate 9 .

The telescopic transfer trolley for switchgear provided by the utility model realizes the convenience and safety of transferring the armored removable AC metal-enclosed switchgear circuit breaker in the maintenance and overhaul process, and provides a safer and more reliable operation for the product. Assure.
