Mechanical inhaul cable type starter for industrial and mining vehicle

Abstract

The invention discloses a mechanical inhaul cable type starter for an industrial and mining vehicle, and relates to the field of mechanical fire extinguishing devices. When a field worker finds a fire, a safety pin on the hand starting end of a pilot device is quickly pulled down, a hand starting pull ring is forcibly pulled out, a firing pin bolt in the pilot starter is pulled out of a bolt hole through an inhaul cable core, then an energy storage spring extends to generate mechanical force to push a firing pin assembly to advance, so that a pilot firing pin pierces a pilot diaphragm installed inside a valve body cap, the pressure in an upper cavity is instantaneously reduced by 50% or above, a pressure difference is formed between the interior of a chemical bottle and the upper cavity, a piston in a valve body moves upwards, a chemical outlet is opened, the chemical is output through a chemical pipeline, a starting process is completed, a starting pipeline does not need to be inflated, the starter is stabler and more reliable, shock-resistant, pulling-resistant, wear-resistant and corrosion-resistant, air leakage is faster, the pressure difference for starting the piston is formed instantly, the starter can adapt to various different installation environments and places, quick-wear parts are easy to replace, and other components can be repeatedly used.

Description

technical field [0001] The invention relates to the field of mechanical fire extinguishing devices, in particular to a mechanical cable starter for industrial and mining vehicles. Background technique [0002] With the rapid development of the country's economy and the continuous growth of industrial output value, the demand for underground mining vehicles has increased, and the situation of vehicles catching fire during use has occurred from time to time. The operating environment of underground mining vehicles is relatively harsh. In this environment, in order to protect life and property safety, a complete, simple and effective fire extinguishing device suitable for harsh environments is required. Due to the risk of live fire extinguishing devices in mines, solid machinery Type fire extinguishing device can effectively avoid this risk. [0003] Use the physical characteristic of gas pressure difference to start mechanical fire extinguishing equipment. The starting method...

AI Technical Summary

Problems solved by technology

[0005] The problem to be solved by the present invention is to provide a mechanical cable-type starter for industrial and mining vehicles, which solves the problem that the poor installation environment of the existing pilot starter can easily lead to pressure relief in the pipeline, which in turn leads to false start or start-up failure of the fire extinguishing device. The start-up pipeline is manually charged, and an external pressure inflation device is required, which is a technical problem that is cumbersome to operate and not easy to install.
