Description

A drawer type power control cabinet assembly with a position sensor

technical field

The invention relates to the field of power control cabinets, in particular to a drawer-type power control cabinet assembly with a position sensor.

Background technique

The power control cabinet is a common component in the field of power switch control. The power control cabinet is used to install various switches, controllers and other power equipment for power control. In order to facilitate maintenance, the power control cabinet usually has drawers for pushing and pulling to maintain the electric equipment inside.

In order to facilitate the automatic push and pull of the drawer, a motor is often set to push and pull it. However, after the drawer is released, it is easy to affect the stability of the cabinet body, and in serious cases, it may cause overturning and cause an accident.

However, the normalized fixing of the cabinet body has the following disadvantages: when the cabinet body needs to be moved flexibly, the normalized fixing operation is complicated.

Contents of the invention

The purpose of the present invention is to provide a power control cabinet assembly, which can be automatically locked when needed, and not locked when not needed so as not to affect its mobility.

The solution of the present invention is: a drawer-type power control cabinet assembly with a position sensor, including a control cabinet part, a drawer push-out part and a foot fixed on the floor, the control cabinet part and the drawer push-out part are fixed together, The control cabinet part is provided with a plurality of power control drawer boxes placed up and down, and the drawer push-out part is used to push out the power control drawer boxes in the control cabinet part. The drawer push-out part includes a support body, a lifting drive part, and a push-out drive part And the lock driving part, the lifting driving part includes a lifting motor, a lifting driving screw and a guide rod, the lifting motor is connected with the upper end of the lifting driving screw to drive the lifting driving screw to rotate, and the lower end of the lifting driving screw rotates through the bearing and the support body Connection, both ends of the guide rod are fixed to the support body, the push drive part includes a push drive part body and a push drive motor and a guide sleeve fixed to the push drive part body, and the left end of the push drive motor is dynamically connected to the threaded sleeve , the threaded sleeve is threadedly matched with the push screw, and the surface of the push screw is provided with a longitudinally extending guide groove, and the guide sleeve has guide teeth for sliding fit with the guide groove; The screw hole and the light hole slidingly matched with the guide rod, the right end of the push drive motor is dynamically connected with the lock drive screw, the lock drive screw is threadedly matched with the lock drive sleeve, and the lock drive sleeve is provided with a sliding groove for Slidingly fit with the sliding tooth on the sliding tooth sleeve, the sliding tooth sleeve is fixed on the body of the driving part; the end of the lock driving sleeve is provided with a dovetail slider;

The lock driving part includes a vertical cylinder, the upper and lower ends of the vertical cylinder are respectively fixed with a slide plate, and two left and right rollers are arranged on the slide plate, and the rollers can move in the left and right direction in the roller track groove on the support body. Rolling forward, the vertical column is provided with a dovetail groove extending up and down for sliding cooperation with the dovetail slider, and a position sensor is arranged in the dovetail groove, and the position sensor is parallel to the electric control drawer box; the vertical column The lower part of the body is hinged with one end of the lock drive link, the other end of the lock drive link is hinged with the middle part of the lock lever, the upper end of the lock lever is hinged with the support body, and the lower end of the lock lever is a lock hook. The middle part of the locking rod is located between its upper end and the lower end, and the opening of the locking hook is opened to the right for hooking the ground feet.

When working, the lifting drive part controls the lifting of the push-out drive part. When the dovetail slider touches the position sensor, the position sensor transmits information to control the lift motor of the lift drive part to stop working first, and the push drive motor of the push-out drive part Rotate to push out the electric control drawer box, at the same time, the vertical column is pushed to the right, so that the lock lever is rotated through the lock drive link, and then the lock hook hooks the ground foot to prevent the electric control drawer box from being pushed out When the rear control cabinet part overturns, when the push drive motor rotates to make the push screw retract, the electric control drawer box can automatically retract under the action of the elastic element.

Through the above scheme, since the drawer is pushed out and driven at the same time, the hook lock device can be synchronously driven to hook lock, so it mechanically ensures that the drawer does not overturn when it is pushed out; and when the drawer is not pushed out, the cabinet body It is not locked, thus not affecting its mobility. Moreover, the drive device for pushing out the drawer can move up and down, so that it is suitable for selectively driving a plurality of drawers arranged up and down. Through the slide plates at the two ends of the vertical column, since the rollers are set on the slide plate, when the push-out driving device moves to the upper end, the driving movement of the hook lock of the vertical column can also be carried out smoothly without causing any damage to the vertical column. The overturning moment of the vertical column causes the vertical column to be stuck in the support body and cannot move. Moreover, the roller of the slide plate moves in the rolling track groove, and its motion is more stable, which ensures its driving motion accuracy for the rotation of the hook lock.
