Abstract

The utility model provides a roof bolter, which is a drilling machine used for civil engineering. The roof bolter accelerates drilling speed, increases drilling efficiency, deepens drilling depth and reduces drilling cost through a novel and reasonable structure, thereby meeting requirements of engineering construction. The roof bolter comprises a support, an operating component, a power component and a working component, the operating component is a hoister consisting of a hoisting barrel, an operating handle and a steel wire rope, the power component consisting of an electromotor and a speed reducer is arranged on a slidable supporting base on the support, an output end of the speed reducer is connected with a drilling stem, the tail end of the drilling stem is provided with a drill bit, and the drilling stem and the drill bit form the working component. The center of the drilling stem is provided with an air hole connected with an air supply hose of an air compressor. The drilling stem can be formed by connecting a plurality of sections according to depth of drilling holes. The roof bolter is used for drilling holes in the civil engineering.

Description

Roof-bolter

Technical field

The utility model relates to a kind of auger, specifically is the roof-bolter that building trade is used to punch.

Background technology

Present used auger equipment such as artificial luoyang spade, the action required personnel are many during work, and speed of fulfiling hole is slow, and efficient is low, and duty cycle is long, and drilling depth is limited, does not satisfy the construction demand; The soil that produces in the boring procedure in addition, Shi Li etc. are difficult to efflux, and exist many defectives, so need a kind of drilling machine that can adapt to the construction demand.

Summary of the invention

The utility model provides a kind of roof-bolter for increasing work efficiency, improve drilling technology, to satisfy the civil works demand at the deficiency that existing drilling machine exists.

The technical scheme roof-bolter comprises support, functional unit, power part and workpiece, support is the basis of equipment, the support left end is equipped with functional unit, described functional unit is a hoist engine, by winding drum, operating grip and wire rope are formed, the bearing that has slideway is installed on the support, motor and reducer are housed on the bearing, and motor and reducer are power part, and the reducer output links to each other with drilling rod, there is through hole at the drilling rod center, its terminal drill bit of installing, drilling rod and drill bit are formed workpiece, and the drilling rod left end connects the air compressor machine flexible pipe, be connected to air shut-off valve in the pipeline, the support right part has bearing control bolt.

Beneficial effect the utility model and existing drilling machine such as artificial luoyang spade relatively have following advantage: 1, save manpower, save operating cost, improved the economic benefit of engineering.Need 4-6 people during artificial luoyang spade pore-forming, roof-bolter only needs 2 people operation; 2, drilling efficiency height has been accelerated the boring progress, has shortened the work period.Finished a hole in artificial luoyang spade 4-5 hour, roof-bolter only needed just finished in 20-30 minute; 3, depth of pore forming can reach 15M, owing to advance things such as the soil that produces in the process, Shi Li by centre bore and the outside gang drill of side opening with the pressure of high pressure draught, and easily discharge, and discharge rate is many, so can increase drilling depth, this is that existing machinery can't be realized; 4, in the boring procedure during as underground pipeline or other obstructions, operating personnel can feel out, avoid dependent failure to take place.
