Mine protective net throwing device

Abstract

The invention relates to a mine protective net throwing device which comprises a support plate. A front baffle is arranged on the front end face of the support plate. An oil cylinder is fixedly arranged on the rear end face of the front baffle. A traction plate is installed on a shaft of the oil cylinder. The left and right ends of the traction plate are each provided with two through holes. The left and right sides of the upper end face of the support plate are each provided with a spring end sleeve. A compression spring is arranged inside a cavity of each spring end sleeve. A throwing spear is communicated with the interior of each compression spring. A pair of supporting longitudinal columns are arranged at the upper portion of each spring end sleeve. Each supporting longitudinal column is sleeved with a pressing rotating block. The rear ends of the supporting longitudinal columns are correspondingly inserted into the through holes in the traction plate. The throwing spears are compressed on the compression springs through the traction plate, and the compression springs are flexibly controlled by the pressing rotating blocks to limit the throwing spears, the throwing spears can be flexibly compressed and released; and in other words, the throwing spears can be flexibly compressed or released, and the throwing spears are utilized for controlling throwing of a protective net, so that the labor intensity of workers is lowered, and the throwing efficiency and the throwing effect of the protective net are improved.

Description

technical field [0001] The invention relates to the technical field of mining machinery and equipment, in particular to a mine protective net throwing device. Background technique [0002] In mining, exposed cliffs or slopes are prone to collapse or rockfall after mining, which poses a great threat to the safety of personnel and property below. In order to reduce or avoid this threat, protective nets are generally set up on the exposed slopes to protect The net is generally made of metal, usually made of steel wire rope, which makes the protective net have a certain degree of flexibility, and is also easy to roll up and carry. When spreading, it will encounter the situation that it is difficult to spread under the obstruction of obstacles. In order to avoid this In this case, when spreading the protective net, the method of throwing is usually used, that is, the protective net is thrown and spread, so as to increase the unobstructed deployment time of the protective net in t...

AI Technical Summary

Problems solved by technology

[0003] Ordinary manual throwing is more difficult, because the protective net made of metal is heavy and difficult to hold, the throwing effect is limited, and the protective net cannot be fully spread, which brings some troubles to the subsequent spreading work
