Description
Technical field
The utility model relates to a kind of stretching device of transverse axis cutting part of heading machine.
Background technology
Transverse axis cutting part of heading machine has two symmetrical cutterheads, and cutting motor is generally fixedly mounted in cutting motor casing, and it does not belong to a part for stretching device.Because cutterhead is directly installed on cutting reducer, the front end weight of cutting units is generally all larger, therefore requires to have the necessary compact conformation of cutting units structure and the reasonable stress of Telescopic.In transverse axis cutting part of heading machine, because two cutterheads are simultaneously during coal petrography cutting or during single cutterhead coal petrography cutting, both sides cutterhead is stressed not etc., two cutterheads is had and around two cutterhead symmetrical center line, rotate trend, thereby drive the structure being attached thereto to rotate, cause stretching structure to destroy.In addition, the existing dust of cutting units stretching structure working environment has again water, in order to prevent that dust and water from entering stretching structure, must have good hermetically-sealed construction.Therefore, resolve the crucial part that the problems referred to above are transverse axis cutting part of heading machine stretching structures.
Utility model content
The purpose of this utility model is: the both sides cutterhead discontinuity existing for current transverse axis cutting part of heading machine, and cutting units stretching structure work under bad environment, need the good series of problems such as sealing, a kind of stretching device of new transverse axis cutting part of heading machine is provided.
The purpose of this utility model is achieved in that a kind of stretching device of transverse axis cutting part of heading machine, cutting units comprises cutting motor casing, flexible junction plate, a pair of telescopic oil cylinder and cutting motor telescopic component, and the cutting reducer being associated with stretching device, cutting motor telescopic component is set in cutting motor casing, cutting reducer is positioned at cutting motor casing end, flexible junction plate is positioned at cutting motor telescopic component and cutting reducer intersection, and be connected with one end of a pair of telescopic oil cylinder, the outer wall of a pair of telescopic oil cylinder other end and cutting motor casing is located by connecting, telescopic oil cylinder drives cutting motor telescopic component to slide in cutting motor casing by flexible junction plate, and promote cutting reducer and move according to flexible direction, cutting motor casing end and cutting motor telescopic component intersection are provided with sealing device, it is characterized in that:
A) described cutting motor telescopic component comprises cutting motor, is respectively equipped with front stretching sleeve and rear extension sleeve with the front and back of cutting motor, and cutting motor telescopic component is connected with cutting reducer with telescopic oil cylinder by the junction plate that stretches by front stretching sleeve ends;
B) on cutting motor casing, have the corresponding flat key that endwisely slips, cutting motor telescopic component is provided with the chute of coupling, and telescopic oil cylinder drives cutting motor telescopic component in the spacing lower slider of the flat key that endwisely slips by flexible junction plate.
In the technical solution of the utility model: the sealing device of cutting motor casing end and cutting motor telescopic component intersection is by the combination sealing arrangement that rotates Glais ring, dust ring, polytetrafluoroethylene gasket and round rubber and form.
The utility model has the advantage of: because cutting motor is along with cutterhead is flexible together, greatly shortened the length of cutting units, made stretching structure compactness and reasonable stress.Because cutting units adopts upper and lower two symmetrical long slip flat keys, solved flexible guiding simultaneously and rotated destruction problem.Owing to adopting, combined seal structure is simple, and sealing effectiveness is good.
