Mine-used intelligent watertight gate

Abstract

The invention discloses a mine-used intelligent watertight gate comprising a watertight gate body, a gate operation driving cylinder, a self-dismounting rail, a digital water level alarm and a control panel. The watertight gate body is arranged at an access and is connected with the access through the gate operation driving cylinder. The digital water level alarm is arranged in water area on the outer side of the watertight gate body and is communicated with the control panel. The self-dismounting rail is arranged below the watertight gate body and is connected with a front route rail through clamping blocks, is hinged with a back route rail through lapping blocks, and is connected with a multi-connecting rod mechanism. A rail driving cylinder is arranged on the multi-connecting rod mechanism. The mine-used intelligent watertight gate has the advantages of reducing basic excavated volume and preventing the driving cylinder from immersing in water for a long time, is convenient to mount, operate and maintain, and has high practicability.

Description

technical field [0001] The invention relates to a waterproof gate, in particular to an intelligent waterproof gate for mines. Background technique [0002] The existing waterproof gate is mainly composed of waterproof door, self-moving clamping rail, hydraulic station and electric control system and other components. There is an oil cylinder drive device on the waterproof gate, and the self-moving clamping rail is driven by the oil cylinder to move the boom upward Rotate, thereby driving the front section of the steel rail to move backward passively and lift up. The gate can realize the automatic closing of the waterproof gate in theory, but in practical application, there are still the following disadvantages: First, the foundation of the clamp rail is too deep, and the hydraulic cylinder driven by the clamp rail has been immersed in water for a long time, and due to the high salt content of non-metallic mines , causing the oil cylinder, piston rod and other rotating parts...

AI Technical Summary

Problems solved by technology

The gate can realize the automatic closing of the waterproof gate in theory, but in practical application, there are still the following disadvantages: First, the foundation of the clamp rail is too deep, and the hydraulic cylinder driven by the clamp rail has been immersed in water for a long time, and due to the high salt content of non-metallic mines , causing the oil cylinder, piston rod and other rotating parts to be easily rusted or even rusted to death

The second is that the lifting of the rail is too high, and it is easy to interfere with the wiring of the electric locomotive

The third is that the rotational torque required by the clamping rail is too large. Once the hydraulic system fails when the water comes in, the clamping rail cannot be removed manually in time.

Fourth, it is not equipped with a digital water level display device. Once the water comes in, the on-site staff cannot report the accurate data in time, and may miss the best time to close the door
