Embodiment 1

[0037] refer to Figure 1-Figure 5 , an electric handcart for a switch cabinet, comprising a frame 1, the top of the frame 1 is fixed with a first mounting plate 3 by bolts, one side of the first mounting plate 3 is provided with a first chute 4, the first chute 4 A first sliding block 6 is slidably connected inside, a mounting bracket 7 is fixed on one side of the first sliding block 6 by bolts, and a first threaded rod 10 is rotatably inserted on the top of the first mounting plate 3, and the first threaded rod 10 is connected with the first threaded rod 10. A slider 6 is threadedly inserted, one side of the mounting frame 7 is fixed with a plurality of insulators 12 by bolts, the other end of the insulator 12 is fixed with an insulating cover 13 by bolts, and a guide post 14 is inserted into the insulator 12, and the guide post 14 passes through Through the insulating cover 13, the other end of the insulating cover 13 is fixed with a contact arm 15 by bolts, the contact arm...

Embodiment 2

[0041] refer to Image 6 , an electric handcart for a switch cabinet, including a side plate 2 with a stepper motor 31 fixed by bolts, the output end of the stepper motor 31 is keyed with a second threaded rod 30, and the second threaded rod 30 passes through the frame. 1. The second threaded rod 30 is inserted into the threaded hole of the switch cabinet, and then the second threaded rod 30 is driven by the stepping motor 31 to rotate, thereby driving the vehicle frame 1 to move forward, so that the plum contact 16 and the The busbar contacts are butted.

[0042] The working principle of this embodiment: during use, the roller 29 is pushed into the track of the switch cabinet, and the second threaded rod 30 is inserted into the threaded hole of the switch cabinet, so that the second threaded rod 30 is driven by the stepping motor 31 to rotate. , and then drive the frame 1 to move forward, so that the plum-blossom contacts 16 are connected to the busbar contacts.

Abstract

The invention relates to the technical field of switch cabinets, and discloses a switch cabinet electric handcart which comprises a frame, a first mounting plate is fixedly connected to the top of the frame, a first sliding groove is formed in one side of the first mounting plate, a first sliding block is slidably connected into the first sliding groove, and a mounting frame is fixedly connected to one side of the first sliding block. A first threaded rod is rotatably inserted into the top of the first mounting plate, the first threaded rod is in threaded insertion with the first sliding block, a plurality of insulators are fixedly connected to one side of the mounting frame, the other ends of the insulators are fixedly connected with an insulating cover, guide columns are inserted into the insulators, the guide columns penetrate through the insulating cover, and a contact arm is fixedly connected to the other end of the insulating cover; the contact arm is electrically connected with the guide column, and the other end of the contact arm is fixedly connected with a tulip contact. According to the invention, the height of the tulip contact can be adjusted, so that the tulip contact can be conveniently connected with bus contacts with different heights, and the butt joint with the bus contacts can be accurately completed.

Description

technical field [0001] The invention relates to the technical field of switch cabinets, in particular to an electric handcart for switch cabinets. Background technique [0002] A handcart is a trolley that is pushed by a person. It is a centrally located draw-out part of the switch cabinet. The main electrical components in the switch cabinet are installed on it. Generally, there are two types of PT handcart and switch (circuit breaker) handcart. When the switch is disconnected, it can be pulled out from the switch cabinet by hand after laying the guide rail for maintenance or replacement. At present, most of the PT handcarts adopt a horizontal push structure, but how to accurately realize the connection of the contact device? And disconnection becomes a more important issue. [0003] At present, most of the existing switchgear electric handcarts have the following shortcomings: in the process of use, the conductive contact arms are mostly fixedly connected, the height is t...
