Abstract
The utility model discloses a heading machine. A cutting head driving device of the heading machine comprises a cutting head mounted at the head part of a cutting arm, a tailstock mounted at the tail of the cutting arm, a speed reducer mounted in the cutting head and a cutting motor mounted on the tailstock, wherein the cutting motor drives the speed reducer through a drive shaft inside the cutting arm. The cutting motor is mounted on the tailstock of the cutting arm, so that the disassembly and the assembly of the cutting motor are convenient, and the maintenance efficiency is high; and the cutting head has light weight, and the gravity center of the machine body is low, so that the stability of the heading machine is good.
Description
Technical field
The utility model relates to a kind of development machine that applies to mining, specifically relates to a kind of cutting head of roadheader transmission device.
Background technology
Known development machine, cut motor, reductor are installed in the cutterhead of cutting arm head all closedly, cut motor transmission speed reducer, reductor drive the body of the cutting head and on pick work.This technical scheme remains deficiency both ways: the one, when the cut motor needs repairing, must carry out dismounting to cutterhead, and the such heavy components of dismounting cutterhead, especially in the mine that lacks hanging device, dismounting is very difficult, and labour intensity is big, and security risk is big; The 2nd, the cut motor is installed in the cutterhead, has increased the weight of cutterhead, because cutting arm generally reaches several meters, when cutterhead is overweight, fuselage stability is bad, can make dangerous phenomenons such as the easy generator bench over of development machine, deflection, displacement, the harm production safety.
Summary of the invention
The utility model aims to provide a kind of cutting head of roadheader transmission device, has both helped easy disassembly cut motor, helps to alleviate cutterhead weight again.
The technical solution adopted in the utility model is: a kind of cutting head of roadheader transmission device, comprise the cutterhead that is installed in the cutting arm head, cutting arm afterbody mounted tailstock, reductor is installed in the cutterhead, the cut motor is installed on the tailstock, and the cut motor is by the power transmission shaft drive speed reducer of cutting arm inside.
The cut motor is installed on the tailstock of cutting arm, when needs dismounting cut motor, need not the dismounting cutterhead, can dismantle maintenance separately to it easily on body, and maintenance difficulty is little, and is easy to operate, the maintenance efficiency height; When the cut motor adopts naked openly when being installed on the tailstock, the dismounting maintenance is simple and effective more.On the other hand, the cut motor is installed on the tailstock, has alleviated cutterhead weight greatly, reduced the body center of gravity, improved the job stability of development machine, eliminated potential safety hazard.
Above-mentioned power transmission shaft can be hollow shaft, power transmission shaft head end fixed installation spline housing, and spline housing is sleeved on the splined shaft, and splined shaft one end stretches in the power transmission shaft internal cavities, and the splined shaft other end is connected with reductor by flange, and the realization power transmission shaft is to the transmission of reductor.With when splined shaft cooperates transmission, the length that splined shaft one end stretches in the power transmission shaft internal cavities can change with need of work at spline housing, when cutting arm elongates or shortens at work, power transmission shaft can be all the time transmission speed reducer reliably.
Above-mentioned power transmission shaft tail end is installed the motor catcher, and the motor catcher is connected with the cut motor, and the cut motor drives power transmission shaft by the motor catcher.
The utility model is by being installed in the cut motor on the cutting arm tailstock, and the cut motor keeps in repair easy accessibility, and cutterhead is in light weight, and the body center of gravity reduces, and is difficult for taking place body and tilts the development machine good stability.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
The specific embodiment
Below in conjunction with accompanying drawing, embodiment of the present utility model is described further.
Fig. 1 shows a kind of cutting head of roadheader transmission device, comprise the cutterhead 2 that is installed in cutting arm 1 head, cutting arm 1 afterbody mounted tailstock 3 is installed reductor 21 in the cutterhead 2, cut motor 4 is installed on the tailstock 3, and cut motor 4 is by power transmission shaft 5 drive speed reducer 21 of cutting arm 1 inside.
