Abstract

The utility model discloses a tunnel rock driller, comprising a vehicle and a working platform arranged on the vehicle. The working platform is provided with a working chamber, an engine, a clutch, a transmission, a rotary shaft and an axle seat supporting the rotary shaft; the head of the front end of the rotary shaft is a drill bit; a conical turnplate is arranged behind the drill bit; the conical surface of the conical turnplate is provided with a plurality of rows of tool rests; the conical bottom plane is provided with a plurality of erect tool rests; the tool rests are provided with alloy tool bits to form cutting tools; the turning radius is the same as the radius of the tunnel; a conveying belt is arranged between pedrail tracks of the vehicle ; and crushed aggregates produced by drilling can be conveyed to the vehicle to be transported. The tunnel rock driller has the advantages of simple structure, convenient mounting and operation, time and labor-saving maintenance and fees conservation, great reduction in operation cost, reduction in construction period, and is particularly suitable for the operation of medium-small projects.

Description

A kind of tunnel rock borer

Technical field:

The utility model relates to a kind of tunneling operation machinery, particularly relates to a kind of tunnel rock borer.

Background technology:

At present, and though railway transportation be on the ground or underground all be that other means of transportation are irreplaceable, still, place an iron railway on the ground and unavoidably excavate the tunnel, and will excavate the tunnel especially at the provided underground railway.Seek advice from by a large amount of on-the-spot investigations with to relevant department and to learn, the main method of excavating the tunnel is punching, blow out, deslagging, not only efficient is low, programming is slow, and expense costliness, in order to address this problem, the national development and production that have tunnel machine, the desk-top development machine and the gondola fetalism stent-type development machine of taking turns that comprise Japan, the function of these development machines has just improved the efficient of boring, the same mode that does not have disengaging to blow out, be characterized in improving the mechanization degree of punching, save a part of artificial, limited shortening the duration, but fundamentally do not solve the mode of tunnel piercing, disclosed in patent documentation " multi-functional complete-section tunnel boring machine ", adopt complicated mechanical mechanism and hydraulic control system to control the head that a large amount of hammer drill and cutting tool are installed and realize the disposable driving moulding in tunnel, no matter the feasibility of this kind machinery how, from its disclosed technology contents, the textural anomaly complexity, though adopt automation control, its maintenance, the time and the expense of maintenance can make the work efficiency of its raising seem not outstanding, and the dismounting of operation process also will expend lot of manpower and material resources.In addition, domestic production enterprise introduces and has produced the shield machine of advanced technology from moral, method two countries, and this kind development machine is bulky, and the preparation time before the operation is long, the expense height, so, inapplicable in, the operation of small-scale engineering.

Summary of the invention:

The utility model provides a kind of tunnel rock borer at the deficiencies in the prior art, technical problem to be solved is to accelerate tunnel piercing speed, structure is simple relatively again, be applicable to the excavation operation in tunnel on a small scale, and maintaining is convenient, dismounting is time saving and energy saving, technical solution adopted in the utility model is as follows: the utility model comprises the operation car, the working platform that is provided with on the operation car, working platform is provided with the service depot, motor, clutch, the axle bed of speed changer and rotating shaft and supporting revolving shaft, it is characterized in that rotating shaft front end termination is by the drill bit that is threaded, it behind the drill bit tapered rotating disk, tapered rotating disk is sleeved in the rotating shaft, and it is affixed with rotating shaft, on the conical surface of tapered rotating disk, be provided with several gang feed tool racks, every gang feed tool rack all arrives the conehead setting along the awl end, knife rest is provided with the alloy cutter head of some, on the awl baseplane, between two knife rests, be provided with several upright knife rests, on each upright knife rest alloy cutter head is installed all, form cutting tool, the radius of gyration is identical with the radius in tunnel, be crisscross arranged between the alloy cutter head on conical surface knife rest and the upright knife rest, guarantee that the cutting face do not stay the dead angle, the operation car is a crawler type, below working platform, also be provided with conveyer belt between two crawler belts, the front end of conveyer belt is articulated on the working platform, and be positioned at below the rotating disk, the rear end of workbench can be articulated on the working platform, also road wheel can be set, conveyer belt is provided with power set separately.

The course of work of the present utility model is as follows: after the maximum size of having determined the cross section, tunnel, adjust the maximum radius of gyration of cutting tool, after having cleared up the job site, the development machine each several part scene of being transported to is assembled, can tunnel after having assembled, ato unit, adjust rotating speed, at first by bit bore, carry out ream operation successively by cutting tool then, cutting tool on upright knife rest enters, and the particle that boring procedure forms falls on the car that connects material that is transported on the conveyer belt after moving car, can be transported easily.

Compared with prior art, the utility model is simple in structure, and fitting operation is convenient, and maintaining is time saving and energy saving, reduces expenses, and can reduce operating cost greatly, and shortens construction period, in being specially adapted to, the operation of engineering on a small scale
