1. Overview
The mine control switch device is mainly suitable for automatic control of large tunnel switches in coal mines, replacing manual switch. In this automatic control device, the electric locomotive driver uses a transmitter (or button) to control the switch position. There is a switch position display above the switch to display the switch position. The device has simple structure, reliable operation and convenient maintenance, which effectively improves working conditions and transportation efficiency.
2. Functional features
Control system When the controller receives the signal from the transmitter (or button), it can control the action of the actuator (cylinder or oil cylinder) to move the switch. When the switch is moved into place, the display shows the switch position.
The display function display can correctly display the current position of the switch.
. Prompt function: When both sides of the switch are not in place, the display will not show the switch position.
, transmitter remote control distance ~ (no obstruction), remote control angle ~
, high switch action sensitivity, action time

Carry out serious coal mine safety inspections. Strictly implement the requirements of superiors on safety inspections. In accordance with the requirements of the Shandong Coal Mine Safety Supervision Bureau and the Provincial Coal Industry Bureau, focus on inspection items, focus on lessons learned and identify problems, not only coal mines, but also group companies.
Carry out coal mine supervision and law enforcement in a targeted manner. A large-scale inspection leading group headed by the main leader of the bureau was established to mobilize the overall situation, set out a timetable, and implement supervision units and responsible persons to focus on the coal mines that they were worried about, using various methods such as comprehensive inspections by large corps, surprise and secret investigations, etc. While improving the effectiveness of supervision, local coal mine safety supervision departments are urged to implement superior arrangements.
Severe punishments and accountability will be strictly enforced without hesitation or mercy. Violations that violate laws and regulations must be severely punished in accordance with the law, and relevant responsible persons must be strictly held accountable. Places and groups with serious problems must be seriously interviewed, criticized, and exposed. Those who fail to supervise work must be held accountable internally.
