Safety early warning device for mining mechanical equipment

Abstract

The invention discloses a safety early warning device for mining mechanical equipment. The safety early warning device comprises supporting hydraulic rods and an arc-shaped supporting plate, wherein hydraulic cylinders are arranged at the positions, corresponding to the supporting hydraulic rods, of the inner side of the arc-shaped supporting plate, the hydraulic cylinders are filled with liquid, the two ends of each hydraulic cylinder are sealed, partition plates are installed in the centers of the hydraulic cylinders, first pistons are installed on the left sides and the right sides of the partition plates, first connecting rods are mounted on the sides of the first pistons, the outer ends of the first connecting rods are hinged to second connecting rods, first early warning devices are arranged between the first pistons and the partition plates, second early warning devices are arranged between the first pistons and the end faces of the hydraulic cylinders, and the hydraulic cylinders are connected with corresponding movable rod supporting the hydraulic rods through supports. By means of the hydraulic system, deformation of the arc-shaped supporting plate can be effectively amplified, and meanwhile the corresponding first early warning device and the corresponding second early warning device are triggered, so that a user can better know the deformation amount and the deformation position, follow-up work is better arranged, and work safety and stability are improved.

Description

technical field [0001] The invention belongs to the field of equipment early warning devices, in particular to a safety early warning device for mining mechanical equipment. Background technique [0002] In the process of mining, it is often necessary to install arc-shaped support plates in the mine to support the mine, and support the arc-shaped support plates through hydraulic rods. However, in the process of mining, some vibrations cause some landslides or rockfall. The arc-shaped support plate can be used to protect the staff below. When the momentum of the falling rock is too large, the arc-shaped support plate may be deformed due to uneven force. To a certain extent, the deformation is acceptable, but When the amount of deformation is too large, some cracks may appear in the arc-shaped support plate, which may cause safety hazards with long-term use.
