Abstract
The utility model discloses a portable combined type fence for a mine. The portable combined type fence comprises small fences, wherein the small fences are welded by waste anchor rods, less than 1 meter in length and equal to 1.5 meters in height; insertion tubes with the lengths of 150 millimeters are respectively welded above and below one side of each small fence, and inserting heads with the lengths of 150 millimeters are respectively welded on the corresponding positions above and below the other side of each small fence; and at least more than two small fences are inserted to form a fence with a needed length through the insertion tubes and the inserting heads. According to the utility model, constructors carry out butting assembly on the small fences according to the needed length and then hang warning signs. The portable combined type fence disclosed by the utility model has the advantages of convenience for construction and transportation, material conservation, beauty, fastness and reliability, solves the problem of frequent maintenance and more importantly provides a reliable and powerful guarantee for downhole safety.
Description
Technical field
The utility model relates to shielding under the coal mine, relates in particular to mining fence.
Background technology
At present, has danger under the coal mine but the tunnel or the leading room that also need to keep need to be placed fence.Traditional wooden fence is to use the batten of a flechette-type shape to be made, and be provided with safety warning-panel, during the down-hole makes, both lost time, manpower, also insecure, the damage phenomenons such as timber rots, distortion will appear after after a while, if untimely maintenance, personnel just might enter dangerous tunnel by mistake, cause the accident.Therefore traditional fence is also more frequent in maintenance, and the work of giving has also brought many inconvenience.
Summary of the invention:
In order to solve the deficiency of above-mentioned technology, the utility model has designed a kind of mining portable combined fence.
A kind of mining portable combined fence, it be the length that is welded into by waste and old anchor pole less than 1m, highly be the little fence of 1.5m, the intubate of respectively welding a long 150mm in the up and down orientation of each little fence one side, respectively weld the plug of a long 150mm at opposite side upper and lower correspondence position, by intubate and plug, plural at least little fence is pegged graft into the fence that needs length again.
The utility model has the advantages that: the constructor in the down-hole as required length little fence docking assembling is got final product, then hang up warning sign.Construct convenient, transhipment is convenient, has not only saved material, but also attractive in appearance, solid and reliable, has also solved the problem of frequent maintenance simultaneously, the more important thing is to downhole safety provides reliable sound assurance.
