Abstract
The unity model relates to a cutting unit(or called a cutting off unit) of a trinity roadheader; specifically a roadhearder cutting unit(or called cutting off unit) which combines a cutting motor of electric(or called a cutting off motor), cutting reducer(or called cutting off reducer) and pars contractilis. The cutting unity ameliorates the rigidity of the roadheader to a large scale and prolongs the service long of the roadheader.
Description
Technical field
The utility model relates to the new construction of tunneling machine cutting portion, the innovation mode of be specially a kind of intensity height, good looking appearance, being convenient to load and unload---Trinitarian tunneling machine cutting portion.
Background technology
Tunneling machine cutting portion is the operating functional entity of this equipment work.Former tunneling machine cutting portion cutting motor, cut reductor, pars contractilis combining form are continuous in twos, and promptly cutting motor and cut reductor two bodies are connected and fixed; Pars contractilis is connected and fixed substep with cut reductor two bodies again and is connected.And the underground working environment has determined the loss of functions of the equipments portions.The long-term thump of equipment moves continuously, causes cut body pars contractilis, reductor, motor the loosening phenomenon that disconnects to occur, and has directly influenced the application life of development machine.
The utility model content
For the tunneling machine cutting body three part bond strengths problem to be strengthened that overcomes present use, the utility model provides a kind of " Trinity structural model ", promptly Trinitarian tunneling machine cutting portion.This structure not only in conjunction with firmly, should not be become flexible, and aesthetic in appearance, is convenient to loading and unloading.
The technical scheme that its technical problem that solves the utility model adopts is:
On the basis that former pars contractilis, cut reductor (or being called cutting speed reducer), cutting motor (or being called cutting motor) are connected and fixed in twos, usefulness tightens together the three by the securing member of cutting motor, cut reductor, pars contractilis simultaneously.
In the utility model, unified connect with four axises, and lock, thereby pars contractilis, cut reductor and cutting motor three parts are combined as a whole with fine thread double nut two ends four jiaos of flange bonding surfaces.
The beneficial effects of the utility model are:
The utility model Trinity adhesion is 2.1 times of former mechanism, has formed a steel body structure, significant prolongation development machine time between overhauls(TBO) and application life.
Description of drawings
Below in conjunction with accompanying drawing the utility model is further specified.
Fig. 1 is a front view of the present utility model.
Fig. 2 is a vertical view of the present utility model.
Among the figure, 1. cutting motor; 2. cut reductor; 3. pars contractilis; 4. cutterhead; 5. serrated nut; 6. closely-pitched thin nut; 7. packing ring; 8. studs; 9. cover plate.
The specific embodiment
As shown in Figure 1 and Figure 2, the utility model is a Trinitarian tunneling machine cutting portion, studs 8 vertically is coupled as one cutting motor 1, cut reductor 2, pars contractilis 3 (four jiaos of positions of flange face), two ends use M48 * 3mm serrated nut 5 and M48 * 3mm closely-pitched thin nut 6 to tighten respectively, firmly fix cutting motor 1, cut reductor 2, pars contractilis 3 as a whole.Among the figure, cutterhead 4 is positioned at the front end of pars contractilis 3.
The course of work of the present utility model is as follows:
According to the needs of form of structure, cutting motor 1, cut reductor 2, pars contractilis 3, cover plate 9 etc. all are designed to corresponding model structure under the prerequisite that guarantees the cutting units function; M48 * 3mm studs 8, M48 * 3mm serrated nut 5, M48 * 3mm closely-pitched thin nut 6 and packing ring 7 are the utility model special purpose parts, the thickness of closely-pitched thin nut 6 is less than serrated nut 5 (hex nut closely-pitched and the combination of hexagon thin nut closely-pitched are widely used in the locking device), its thickness is 24mm according to GB/T6173-2000, the main effect of closely-pitched thin nut 6 is that thin nut is used as secondary nut in locking device, plays tight lock effect.
The utility model adopts novel mechanism that cutting motor, cut reductor, the pars contractilis three parts polyphone of tunneling machine cutting portion are combined as a whole, and the new model that certainly will will set up cutting motor, cut reductor, pars contractilis, cover plate combination is to satisfy the needs of function and assembling.For example: its casing of cut reductor will be designed to and not only satisfy the driving function but also be applicable to novel assembled construction.Front end-plate is designed to trapezoidal, and it is consistent that want in end plate axis hole, front and back, and guaranteed reliable functioning and intensity.Equally cutting motor and pars contractilis are designed and the corresponding to structure of cut deceleration body simultaneously.Make up according to utility model structure design loam cake.The comprehensive above-mentioned design of having finished Trinitarian tunneling machine cutting portion utility model.
Claims (2)
1, a kind of Trinitarian tunneling machine cutting portion is characterized in that: with the securing member by cutting motor, cut reductor, pars contractilis simultaneously the three is tightened together.
2, according to the described Trinitarian tunneling machine cutting of claim 1 portion, it is characterized in that: the flange bonding surface of the flange bonding surface of described cutting motor, the flange bonding surface of cut reductor, pars contractilis connects with the securing member that connects.
