Abstract
The utility model discloses a multifunctional high strength front canopy device which comprises a 3-inch seamless steel pipe front canopy main body, wherein the length of the front canopy main body is not less than 3.2 meters, two ends of the seamless steel pipe are welded in sealing mode by steel plates, after the seamless steel pipe is sealed, the seamless steel pipe is connected with a 2-inch water pipe rapid joint, and a plurality of high pressure nozzles which are evenly distributed are welded on the pipe wall of the seamless steel pipe. The multifunctional high strength front canopy device not only plays the role of temporary supporting, and driving head-on coal dust is well controlled.
Description
Technical field:
The utility model relates to temporary lining and the device for reducing dust of mine comprehensive digging equipment driving face.
Background technology:
Driving face adopts fully-mechanized digging machine under the coal mine that has at present, and forestope is adopted in the temporary lining during driving mostly, and forestope can protract and play good supporting effect on meeting head on; Dust prevention during driving is to establish inside and outside shower nozzle at fully-mechanized digging machine, but the coal dust of work plane depends merely on the inside and outside spraying of fully-mechanized digging machine and can not get controlling preferably, and constructor's health causes serious threat to meeting head on.
Summary of the invention
Be the solution large problem of coal dust of meeting head on, a kind of multi-functional high strength front cantilever apparatus of can temporary lining, again can efficient spray of the utility model design.
Technical solutions of the utility model are: a kind of multi-functional high strength front cantilever apparatus, it is to adopt length to be not less than 3 inches seamless steel pipes of 3.2 meters as the forestope main body, the seamless steel pipe two ends seal with Plate Welding, sealing is 2 inches fast joint of waterpipe on the seamless steel pipe rear end connects afterwards, a plurality of equally distributed high pressure nozzles of welding on the seamless steel pipe tube wall.
When the utility model uses, this device is resembled the common forestope with rockbolt installation on the down-hole driving face is met head on top board, 2 inches dustproof water pipes of work plane are plugged on the fast joint of waterpipe, by hydraulic pressure from nozzle with vaporific ejection, thereby reach dust-laying effect.Not only play the temporary lining effect, and the boring head coal dust is controlled preferably.This product with compact structure is used for mine comprehensive digging equipment temporary support for drivage face and depositing dust, and is at one stroke dual-purpose, safe and reliable.
Description of drawings
Fig. 1 is the schematic diagram of the utility model embodiment.
Marginal data, the 1-steel pipe; The 2-fast joint of waterpipe; The 3-high pressure nozzle; The 4-2 inch water pipe that prevents dust; The 5-anchor pole.
The specific embodiment:
As shown in Figure 1, a kind of multi-functional high strength front cantilever apparatus, it is to adopt length to be not less than 3 inches seamless steel pipes 1 of 3.2 meters as the forestope main body, seamless steel pipe 1 two ends seal with Plate Welding, sealing is 2 inches fast joint of waterpipe 2 on the seamless steel pipe rear end connects afterwards, the some equally distributed high pressure nozzles 3 of welding on the seamless steel pipe tube wall.During use, this device resembled the common forestope be installed in the down-hole driving face with anchor pole 5 and meet head on the top board, 2 inches dustproof water pipes 4 of work plane are plugged on the fast joint of waterpipe 2, by hydraulic pressure from high pressure nozzle 3 with vaporific ejection, thereby reach dust-laying effect.
