Abstract
The utility model relates to an important component of a coal mine laneway heading machine, in particular to a cutting part of a heading machine, which is provided with a cutting head, a cutting arm and a driving part, wherein one end of the cutting arm is connected with the driving part, the cutting head is installed at the other end of the cutting arm, a telescopic oil cylinder is respectively arranged at both sides of the driving part, one end of each telescopic oil cylinder is connected with the driving part, and the other end of each telescopic oil cylinder is connected with the cutting arm. The utility model adopts two telescopic oil cylinders for telescopic driving, balances the stress condition of a telescopic part, solves the problems of influence on the service life of equipmentcaused by the unbalance loading of a unilateral oil cylinder existing in the prior art and the like, prolongs the service life of the telescopic part, and simultaneously properly improves the drillingcapability of the cutting head.
Description
Technical field
The utility model relates to the vitals of coal mine roadway development machine, is specially a kind of tunneling machine cutting portion.
Background technology
The colliery when excavation operation, needs fuselage stable with development machine, therefore adopts the working method of location cut mostly, so just need cutterhead self to stretch, telescopic oil cylinder one end in the past links to each other with pars contractilis, and the other end links to each other with cutting motor, and adopts single oil cylinder.It is not very balanced making pars contractilis stressed like this, and makes the housing of cutting motor bear pulling force, and this structure can be influential to the application life of equipment.
The utility model content
The purpose of this utility model is to provide a kind of tunneling machine cutting portion, adopts two drivings that telescopic oil cylinder stretches, and the stressing conditions of balance pars contractilis solves the one-sided cylinder structure unbalance loading that exists in the prior art, influences the problems such as application life of equipment.
The technical solution of the utility model is:
A kind of tunneling machine cutting portion, described tunneling machine cutting portion is provided with cutterhead, cutting arm, driving section, cutting arm one end links to each other with the driving section, the cutting arm other end is installed cutterhead, arrange telescopic oil cylinder respectively in the both sides, driving section, each telescopic oil cylinder one end is connected with the driving section, and the telescopic oil cylinder other end is connected with cutting arm.
Described tunneling machine cutting portion is characterized in that: the telescopic oil cylinder horizontal arrangement.
The beneficial effects of the utility model are:
The utility model tunneling machine cutting part device, adopt two telescopic oil cylinders of horizontal arrangement flexible simultaneously, realize the expanding-contracting action of cutterhead, realize that both sides promote simultaneously, the stressing conditions of pars contractilis is improved, cutting units is subjected to the load of balance, solves the problem of one-sided cylinder structure unbalance loading, improves the application life of pars contractilis.Simultaneously, also suitable raising the drilling ability of cutterhead.
Description of drawings
Fig. 1, Fig. 2 are the cutting units structural representation that contracts of the present utility model; Wherein, Fig. 1 is a front view; Fig. 2 is a vertical view.
Among the figure, 1 cutterhead; 2 cutting arms; 3 driving sections; 4 power parts; 5 oil cylinders.
The specific embodiment
As shown in Figure 1 and Figure 2, the utility model is a tunneling machine cutting portion, this cutting units mainly comprises cutterhead 1, cutting arm 2, driving section 3, power part 4 etc., driving section 3 links to each other with power part 4, cutting arm 2 one ends link to each other with driving section 3, and cutting arm 2 other ends are installed cutterhead 1, at telescopic oil cylinder 5 of each horizontal arrangement of 3 both sides, driving section of tunneling machine cutting portion, each telescopic oil cylinder 5 one end is connected with driving section 3, and telescopic oil cylinder 5 other ends are connected with cutting arm 2.
In the tunneling machine cutting of the present utility model portion, when telescopic oil cylinder 5 moves, telescopic oil cylinder 5 rear ends are fixed on the driving section 3 of tunneling machine cutting portion, telescopic oil cylinder 5 front ends promote cutting arm 2 and move forward, cutting arm 2 promotes cutterhead 1 again and moves forward, thereby realizes the moving process of cutterhead.
Claims (2)
1, a kind of tunneling machine cutting portion, it is characterized in that: described tunneling machine cutting portion is provided with cutterhead, cutting arm, driving section, cutting arm one end links to each other with the driving section, the cutting arm other end is installed cutterhead, arrange telescopic oil cylinder respectively in the both sides, driving section, each telescopic oil cylinder one end is connected with the driving section, and the telescopic oil cylinder other end is connected with cutting arm.
2, according to the described tunneling machine cutting of claim 1 portion, it is characterized in that: the telescopic oil cylinder horizontal arrangement.
