Embodiment 1

[0015] Such as figure 1 Shown: a driving signal locking system at the wellhead of an auxiliary well, including signal and driving locking devices, the signal and driving locking devices are installed at the upper and lower openings of the auxiliary well, and two sensors are connected in series to the signal and driving locking circuits respectively , as a vehicle operation, signal blocking, it includes the following steps:

[0016] (1) When the hooker turns the locking link (magnet) to the "operating" position, the signal worker can operate the car. After the operation is over, the hooker turns the locking link to the "signal" position. The signal worker can signal to move the tank;

[0017] (2) When the tank is in place, the hook worker checks the vehicle in the tank, and after confirming that the vehicle is allowed to operate, turn the locking link to the "driving" gear, and the signal worker can operate the vehicle (open the safety door, drop the cradle);

[0018] (3) If ...

Abstract

The invention discloses a signal locking system for shaft machine operation at an auxiliary shaft. The system is characterized by comprising signal and machine operation locking devices, wherein the signal and machine operation locking devices are mounted at upper and lower openings of the auxiliary shaft and are connected in series to signal and machine operation locking loops through two sensors respectively for machine operation and signal locking. By means of the system, unsafety of whistling is replaced, safety operation of a cager is regulated, injury accidents at a safety door or a vehicle are avoided, and safety operation of the shaft is ensured.

Description

technical field [0001] The invention relates to the technical field of mine transportation, in particular to a driving signal locking system at the wellhead of an auxiliary shaft. Background technique [0002] The opening of the wellhead operation (safety door, cradle, cart machine, front resistance, etc.) needs to be confirmed by the whistle of the hook before it can act, which plays a role of safety protection. The original design did not consider the unsafe factors of people. Weekly, when people are getting on and off the cage, the hooker is inserting and pulling out the tank curtain, dismantling the ground lock, or someone is working in the tank, if the signal worker is not focused and mishears the hooker's instructions, resulting in misoperation (open or close the safety door, If the cradle rises or falls, or the cart moves), the personnel in the tank will be crushed. Based on this, a kind of auxiliary wellhead operation signal locking system is studied, which solves t...
