Abstract
The invention discloses an expansion device of a hard rock tunneling machine, comprising an expansion part, a cutting decelerator, a frame body, a telescopic oil cylinder and a cutting motor. A front end support point of the telescopic oil cylinder is connected to the expansion part, a back end support point of the telescopic oil cylinder is connected with the interior of the frame body, the cutting decelerator is connected with the frame body, and the cutting motor is connected with the frame body in parallel and arranged in the frame body. The telescopic oil cylinder passes through the frame body and is arranged inside the frame body, thus the width of a cantilever section expansion protection cylinder can be reduced, the total width of the tunneling machine is further reduced, and the rigidity of the protection cylinder is increased at the same time; in addition, the expansion device of the hard rock tunneling machine, disclosed by the invention, is more beneficial to cutting and has reasonable appearance and a compact structure.
Description
Technical field
The present invention relates to a kind of stretching device, particularly relate to a kind of hard rock mole stretching device.
Background technology
Boom-type roadheader has telescopic and not telescopic two kinds.Not telescopic development machine is owing to the non-adjustable scope of application that limits development machine of cutting units length, so the telescopic development machine scope of application is wider.Present stage, telescopic development machine primary structure was that pars contractilis is connected on the cut reductor, and cut reductor and cutting motor link, and telescopic oil cylinder front end fulcrum places on the flexible protection tube, the rear end fulcrum directly and motor link.In the work,, heavy then change motor if this structure motor side fulcrum place damages maintenance difficult.Above-mentioned stretching structure is many to be used in coal road, half coal road, seldom uses owing to its rigidity deficiency for the total rock section.
Summary of the invention
It is strong that technical problem to be solved by this invention provides a kind of rigidity, manufacturing, use, easy to maintenance, and outward appearance is reasonable, the hard rock mole stretching device of compact conformation.
In order to solve the problems of the technologies described above, hard rock mole stretching device provided by the invention, comprise pars contractilis, cut reductor, support body, telescopic oil cylinder and cutting motor, the front end fulcrum of described telescopic oil cylinder is connected on the described pars contractilis, the rear end fulcrum of described telescopic oil cylinder and described support body inside link, described cut reductor is fixed in the support body, its two ends link to each other with cutting motor and pars contractilis respectively, and described cutting motor and described support body link and place in the described support body.
The present invention can adopt following optimal technical scheme:
Described pars contractilis also is provided with flexible protection tube, and the front end fulcrum of described telescopic oil cylinder is connected on the flexible protection tube of described pars contractilis.
Connecting between pars contractilis and cut reductor and/or cut reductor and the cutting motor is that spline or shaft coupling connect.
Described telescopic oil cylinder is two and is symmetricly set on described support body both sides.
Beneficial effect of the present invention: hard rock mole stretching device provided by the invention, have reasonable in design, rigidity is strong, manufacturing, use, easy to maintenance, outward appearance is reasonable, the characteristics of compact conformation.
Adopt the hard rock mole stretching device of optimal technical scheme, adopt implicit form list (two) telescopic oil cylinder, be arranged in the support body inside of development machine.Telescopic oil cylinder front end fulcrum places on the flexible protection tube, and rear end fulcrum and support body link, and cutting motor and support body link, and places in the support body, has guaranteed that promptly linking intensity plays a protective role to cutting motor again.
The front end fulcrum that the oil cylinder that contracts is put is on the flexible protection tube; the rear end fulcrum is positioned at the outside of support body inside; owing to will guarantee that telescopic oil cylinder is on same level or the vertical plane, so just can make the width of flexible protection tube be unlikely to too wide, guaranteed rigidity as the protection tube of group welding piece.
Even the present invention's development machine adopts two telescopic oil cylinders, can not strengthen tunneling machine cutting portion appearance and size yet.Two telescopic oil cylinders can be arranged symmetrically in the support body both sides respectively, all place support body inside, are passed with flexible protection tube telescopic oil cylinder fulcrum by the support body front end to connect.
Description of drawings
Fig. 1 is a hard rock mole stretching device structural representation;
Fig. 2 is single telescopic oil cylinder hard rock mole stretching device vertical view;
Fig. 3 is two telescopic oil cylinder hard rock mole stretching device vertical views.
The specific embodiment
The invention will be further described below in conjunction with the drawings and specific embodiments.
Referring to Fig. 1 and Fig. 2; pars contractilis 1 links with an end of cut reductor 4; the other end of cut reductor 4 and support body 5 link; cutting motor 6 links with support body 5 and places in the support body 5; the front end fulcrum of first telescopic oil cylinder 3 is connected on the flexible protection tube of pars contractilis 1, and the rear end fulcrum of first telescopic oil cylinder 3 and support body 5 inside link.
As depicted in figs. 1 and 2, pars contractilis 1, cut reductor 4 and support body 5, and support body 5 all is to be connected and fixed with high-strength bolt and bearing pin 2 with cutting motor 6,3 liang of fulcrums of the first telescopic oil cylinder flexible protection tube that lays respectively at pars contractilis 1 is gone up and is reached support body 5 inside.During work, pars contractilis 1 by first telescopic oil cylinder 3 carry out elastic.
Referring to Fig. 3, even the development machine pars contractilis adopts two oil cylinders i.e. first telescopic oil cylinder 3 and second telescopic oil cylinder 7 as can be known, because first telescopic oil cylinder 3 and second telescopic oil cylinder 7 are arranged in support body 5 both sides, all place support body 5 inside, also can not strengthen tunneling machine cutting portion appearance and size.Play great role for the type quality that improves development machine like this.
Fig. 1 and Fig. 2 advance the machine stretching device for single cylinder type; Fig. 3 advances the machine stretching device for two cylinder types.In two kinds of structures, first telescopic oil cylinder 3 and second telescopic oil cylinder 7 all are arranged in the inside of the support body 5 of development machine, and the bearing of front fulcrum is welded on the flexible protection tube, in the bearing welding of rear fulcrum and the inner chamber of support body 5, are the box-type welded construction, and structural rigidity is good.Because telescopic oil cylinder is arranged in the inside of support body 5, reduce flexible protection tube upper cylinder bearing and stretched out width, also have significant improvement for the welded flexible rigidity of tube of protecting.
The above only is a preferred implementation of the present invention; should be pointed out that for those skilled in the art, under the prerequisite that does not break away from the principle of the invention; can also make some improvements and modifications, these improvements and modifications also should be considered as protection scope of the present invention.
