Abstract

The utility model belongs to an electrical control device, in particular to a mine electromechanical combination locking explosion prevention controlling box used for the air compressor. The controlling box is composed of a box body (8), a door (4), a door spindle (2), a limited block (7), an eccentric wheel (6) and a handle (3), wherein a pushbutton socket (15) is fixed below a pushbutton (12), the pushbutton (12) is movably installed in the pushbutton socket (15), a wrench seat (17) is fixed on the box body (8) below the pushbutton (12), a copper sleeve (20) is fixed in the wrench seat (17), an operating axle (19) is movably fixed in the copper sleeve (20), the right corner of the operating axle (19) is fixedly connected with a wrench (11) by using a wrench fixing screw (18), a release fork (21) is fixed at the left end, a square hole (21) is provided on the release fork (21). The door can not be opened when the controlling box is power on, and the power is required to be off when the door is opened, therefore the electromechanical combination locking is realized, and the safety of the working personnel in repair and maintenance can be guaranteed.

Description

The explosion-proof control cabinet of electromechanical combination locking

Technical field

The utility model belongs to electrical control gear, the explosion-proof control cabinet of electromechanical combination locking that particularly a kind of mining air compressor machine uses.

Background technology

At present, the explosion-proof control cabinet that mining air compressor machine uses does not have the electromechanical combination blocking function, therefore, in daily maintenance and repair process, because operation is improper, tends to cause dangerous accident.

Summary of the invention

The purpose of this utility model is to overcome above-mentioned technical deficiency, and a kind of explosion-proof control cabinet of electromechanical combination locking that guarantees the maintenance and repair personal security is provided.

The technical scheme that the utility model technical solution problem adopts is: a kind of explosion-proof control cabinet of being made up of casing, door, door-hinge, guide vane end stop, eccentric wheel and handle of electromechanical combination locking, be characterized in that the casing right side fixes a push-button socket, button is housed in the push-button socket versatilely, between push-button socket and the button spring is housed, the button left end is fixed a contact with lock; Be fixed on spanner seat on the casing below the button, copper sheathing of spanner seat internal fixation is equipped with an operating axis versatilely in the copper sheathing, and the operating axis right-hand member is fixedlyed connected with spanner with the spanner hold-down screw, and left end is fixed a shifting block, and shifting block is provided with square hole; With nut of bolt and block, nut is connected with screw flight on the casing in spanner left side, and the screw rod right-hand member inserts in the recess of establishing on the spanner, and left end is fixed a limiting plate.

The beneficial effects of the utility model are: can not open the door during this control cabinet energising, can not switch on when opening the door, realize the electromechanical combination locking, guarantee staff's being perfectly safe in maintenance and repair.
