Description

Technical Field

[0001] This utility model relates to the field of switchgear technology, and in particular to a small removable AC switchgear. Background Technology

[0002] In power distribution systems, small withdrawable AC switchgear is widely used in low-voltage distribution circuits in industrial plants, commercial buildings, and residential communities due to its advantages such as compact structure, small footprint, and convenient operation and maintenance. It undertakes core functions such as power distribution, circuit protection, and equipment control. Among them, the trolley assembly, as the core moving part of the switchgear, integrates key electrical components such as circuit breakers and disconnect switches. Its withdrawable design enables flexible switching between "live plugging and unplugging" and "offline maintenance." When electrical components need maintenance or replacement, operators can pull the trolley assembly out of the cabinet without disconnecting the power to the entire switchgear, greatly improving operation and maintenance efficiency and power supply reliability. In actual use, the handcart is connected to the inside of the cabinet by a sliding structure. However, the traditional sliding slider is prone to jamming during the handcart's push-out process. The sliding connection structure does not have the ability to support heavy objects, which makes the maintenance table very easy to bend and be damaged during the handcart's push-out process, thus affecting the handcart's push-out maintenance. Therefore, this application provides a small removable AC switchgear to meet the requirements. Utility Model Content

[0003] The technical problem to be solved by this utility model is to provide a small removable AC switch cabinet that can prevent the handcart from getting stuck during the withdrawal process, and at the same time avoid the technical problem of the maintenance platform tilting forward due to excessive weight.

[0004] To solve the above-mentioned technical problems, this utility model provides the following technical solution: A small removable AC switch cabinet, including a cabinet body; A partition board, which is fixedly connected to the inside of the cabinet and divides the cabinet into upper and lower sections; A handcart assembly is installed inside the cabinet. The handcart assembly includes a handcart body, a connecting slide rod is fixedly connected to the top of the outer surface of the handcart body, a maintenance platform is fixedly connected to the top of the connecting slide rod, a rectangular through hole is opened on the top of the partition plate, and the connecting slide rod is slidably disposed on the inner wall of the rectangular through hole. A support assembly is disposed on the inner wall of the inspection platform. The support assembly includes a threaded rod that is threadedly connected to the inner wall of the inspection platform, and a support block is fixedly connected to the bottom end of the threaded rod. A fixing component is provided between the cabinet and the maintenance platform.

[0005] By setting up the handcart assembly, the handcart body is guided during the pushing process, and the connection between the connecting slide rod and the maintenance platform is supported. At the same time, the maintenance platform is supported by the support assembly to prevent the connecting slide rod from bending and being damaged.

[0006] Optionally, a first mounting rod is fixedly connected to the bottom of the handcart body, and a first guide wheel is fixedly connected to the bottom end of the first mounting rod. An auxiliary through hole is opened at the bottom of the cabinet body, and the first mounting rod is disposed inside the auxiliary through hole.

[0007] The first guide wheel allows the handcart body to move.

[0008] Optionally, a rectangular connecting block is fixedly connected to the outer surface of the connecting slide rod, and wheel frames are symmetrically fixedly connected to both sides of the rectangular connecting block. A second guide wheel is rotatably connected to the inner wall of the wheel frame, and guide grooves are symmetrically opened on both sides of the rectangular through hole. The second guide wheel is disposed inside the guide groove.

[0009] With the help of the second guide wheel, it can work with the guide groove to assist in guiding and moving the connecting slide rod.

[0010] Optionally, a second mounting rod is fixedly connected to the bottom of the inspection platform, and a third guide wheel is fixedly connected to the bottom end of the second mounting rod. A wheel groove is provided on the top of the partition plate, and the third guide wheel is disposed inside the wheel groove.

[0011] The third guide wheel can work with the wheel groove to make the guide movement of the maintenance platform more stable, and at the same time it can support and guide the maintenance platform.

[0012] Optionally, an operating block is fixedly connected to the top of the threaded rod, and a support slot is provided on the top of the handcart body, with the support block engaging with the inner wall of the support slot.

[0013] The support slot and support block can support the maintenance platform, thus preventing bending at the connection between the connecting rod and the maintenance platform.

[0014] Optionally, the top of the inspection platform is provided with a storage slot, and the support block is fitted into the storage slot.

[0015] The storage slot allows the support block to be stored away when not in use, or when the maintenance table is inside the cabinet.

[0016] Optionally, the fixing component includes a second screw hole, which is opened on one side of the inspection platform. An L-shaped plate is fixedly connected to one side of the cabinet. A first screw hole is opened on one side of the L-shaped plate. Threaded clamps are threadedly connected to the inner walls of the first screw hole and the second screw hole.

[0018] Compared with the prior art, this utility model has at least the following beneficial effects: By setting up the handcart assembly, the second guide wheel, in conjunction with the guide groove, allows the connecting slide rod to move smoothly within the rectangular through hole, preventing jamming. Simultaneously, the third guide wheel guides and supports the maintenance platform, while the support assembly supports the maintenance platform, thus preventing bending and breakage at the connection between the maintenance platform and the connecting slide rod.

[0019] By setting up a fixing component, the inspection table can be fixed in place by the threaded clamp and the first and second threaded holes. This prevents the inspection table from easily moving during maintenance, which is very convenient.
