The invention discloses an explosion-proof tank core drawing positioning and locking mechanism in an underground coal mine, and solves the problem of core positioning and locking of the existing electric control cabinet core. The mechanism adopts the structure that a limiting block (15), with a limiting pin groove (16), is fixedly arranged at the lower end of the outer side of a core (3); a notch (6) is formed in the end part of the outer side of a core drawing guide rail (2); the front end of an oscillating arm (8) is hinged to an oscillating arm hinged shaft (7); a limiting short shaft (14) is arranged on the inner side surface of the front part of the oscillating arm (8); the limiting short shaft (14) is movably matched with the limiting pin groove (16) formed in the limiting block (15); a supporting oscillating bar hinged shaft (11) is arranged on the inner side surface of the oscillating arm (8); the upper end of a supporting oscillating bar (12) is hinged to the supporting oscillating bar hinged shaft (11); a supporting shaft (9) is arranged on the inner side surface of an explosion-proof tank body (1); a supporting opening (13) in the lower end of the supporting oscillating bar (12) is movably matched with a supporting shaft (9). The mechanism has the characteristics that the structure is simple, and the use is convenient.
Description
technical field [0001] The invention relates to an electric control cabinet for underground coal mines, in particular to a positioning and locking mechanism for a pull movement in the electric control cabinet. Background technique [0002] With the improvement of automation in coal mining, the centralized control of underground mine explosion-proof electrical equipment is getting higher and higher. Mine explosion-proof vacuum feed switch is a protection device commonly used in underground mines. It has three-phase symmetrical leakage and leakage blocking protection when it is used as a main switch, and it is a backup protection for branch switch leakage protection. The core is the core component of the mining explosion-proof vacuum feed switch. The core is the executive component that realizes the reliable plugging of the main circuit and the three-phase conductive bar of the circuit breaker. During the installation and maintenance of the electric control cabinet, it is ofte...
