Description

Technical Field

[0001] This utility model relates to an improvement in the structure of an elevator control cabinet, specifically an elevator control cabinet with STO (Standard Tolerance) function. Background Technology

[0002] STO (Safe Torque Off) function is a function used to disconnect the output torque of the drive, which can be used for emergency stopping of the equipment. The existing elevator host is controlled by contactors, which mainly control the start, stop and operation status of the host. However, contactors produce a lot of noise when they engage and disengage, which does not meet the requirements for quiet environments. Therefore, an integrated host controller is needed to reduce noise and needs to be integrated into the elevator control cabinet. Thus, the elevator control cabinet needs to be improved. Utility Model Content

[0003] The purpose of this utility model is to overcome the above-mentioned deficiencies in the prior art and to provide an elevator control cabinet with STO function.

[0004] The technical solution adopted by this utility model to solve the above problems is as follows: The elevator control cabinet includes a cabinet body and a cabinet door. An installation space is provided inside the cabinet body. The upper part of the installation space is designated as a power management area, and the lower part as an equipment installation area. The power management area is equipped with a start / stop controller and a leakage protection device. The equipment installation area is equipped with a control unit and a main board. The control unit is fixed to the back panel inside the cabinet door. The main board is located at the front of the control unit and is upright and fixed to the cabinet body. The main board has connectors, and all control circuits are connected through these connectors. This elevator control cabinet design houses the control unit, with the control unit positioned at the rear and directly fixed to the back panel of the cabinet body. The fixed structure is stable and reliable, and provides good protection. The main board, mainly used for wiring, is located on the front side, which is directly visible when the door is opened, facilitating wiring and troubleshooting. The power management functions, which require control operation, are located at the top, facilitating elevator start / stop control. Key components include control switches and emergency stop buttons. The integrated structure has good performance, low noise during operation, and a compact design, contributing to the miniaturization of the control cabinet.

[0005] Furthermore, a heat sink, which is an air-cooled heat sink, is located near the control unit. Ventilation holes are provided on the side of the cabinet, and a cooling fan is installed on the side wall of the power management area cabinet to guide airflow outwards. Heat generated during the operation of the control unit is dissipated by the heat sink and through the ventilation holes. The cooling fan accelerates airflow and improves heat exchange efficiency.

[0006] Furthermore, the mainboard is equipped with an STO function wiring port, which connects to the STO function terminal of the integrated control unit. Simultaneously, the STO function wiring port is connected to the elevator's operating status sensor. The integrated control unit has an STO function, allowing the functional structure to be routed onto the mainboard, facilitating wiring and maintenance without requiring the mainboard to be removed for wiring to the integrated control unit.

[0007] Furthermore, a protective cover is provided at the front of the integrated control unit, covering the front area of ​​the integrated control unit and the corresponding mainboard area. The protective cover serves to prevent collisions and splashes, protecting the integrated control unit and preventing damage to the equipment and circuitry.

[0008] Compared with the prior art, this utility model has the following advantages and effects: This design is an improved control cabinet structure with STO function, which can effectively reduce the noise during elevator operation, meet the requirements of a high-quiet environment, and the structure of the control cabinet is clear and reliable, the operation is stable, and it is convenient to miniaturize the control cabinet, so that it can be used in a variety of elevator environments.
