Description

Technical Field

[0001] The utility model relates to the field of PLC control cabinets, in particular to a PLC control cabinet with a lifting function. Background Art

[0002] The control cabinet is a combination of switchgear, measuring instruments, protective electrical appliances and auxiliary equipment assembled in a closed or semi-closed metal cabinet or on a screen according to the requirements of electrical wiring. Its layout should meet the requirements of normal operation of the power system, facilitate maintenance, and not endanger the safety of personnel and surrounding equipment. In normal operation, the circuit can be connected or disconnected with the help of manual or automatic switches. In case of failure or abnormal operation, the circuit can be cut off or alarmed with the help of protective electrical appliances. Various parameters in operation can be displayed by measuring instruments, and some electrical parameters can also be adjusted, and prompts or signals can be issued for deviations from normal working conditions. It is often used in various power generation, distribution and substations.

[0003] For example, a control cabinet with a lifting function disclosed in the utility model with authorization announcement number CN213026995U can drive the threaded rod to rotate through the operation of a motor. At this time, under the transmission of the threaded rod and the threaded groove, the guide plate and the connecting plate will slide relative to each other, thereby driving the control cabinet body to move in the vertical direction and adjusting the overall height of the control cabinet body. When the control cabinet is lifted and lowered, the positioning column will automatically return to its original position under the reaction of the reset spring after the control cabinet body is lifted and lowered, so that the outer end of the positioning column can be engaged in the positioning groove. However, there is a distance between the positioning grooves. When the positioning column moves between the positioning grooves, the positioning column cannot be inserted into the positioning groove, which makes it impossible to provide auxiliary support for the control cabinet body and enhance its stability.

[0007] As a preferred technical solution of the utility model, a plurality of mounting holes are provided on the tops of the two mounting plates.

[0008] As a preferred technical solution of the utility model, a connecting plate is fixedly connected between the two mounting plates.

[0009] As a preferred technical solution of the utility model, the threads on both sides of the first screw rod rotate in opposite directions.

[0010] Compared with the prior art, the utility model can achieve the following beneficial effects:

[0011] 1. By designing a clamping plate, the first screw rod fixedly connected to the double-axis motor is driven to rotate through operation, and the rotation of the first screw rod drives the clamping plate sleeved on the outside to move inward, so that the clamping plate clamps and fixes the support column, and the support block fixedly connected to the clamping plate is driven to move through the movement of the clamping plate, and the control cabinet is auxiliary supported by the support plate movably connected to the support block, thereby realizing auxiliary support for the control cabinet and enhancing its stability;
