Abstract
The utility model relates to a cutting mechanism for a heading machine. The cutting mechanism comprises a cutting shaft and a first cutting head arranged at one end of the cutting shaft, wherein the first cutting head is connected with the cutting shaft through an expansion coupling sleeve. In the cutting mechanism for the heading machine, the expansion coupling sleeve replaces the conventional spline and bolt connection, the connecting mode is simpler, and when the expansion coupling sleeve is installed, an expansion bolt is only screwed according to the required torque without heating, cooling or pressurizing equipment and the expansion coupling sleeve is convenient to adjust. By using friction transmission, the expansion coupling sleeve does not generate concentrated stress and has high capacity of bearing axial load.
Description
Technical field
The utility model relates to a kind of parallel or perpendicular to the cutting machine of coal seam slotting, particularly relates to a kind of cutting mechanism of development machine.
Background technology
Development machine is the plant equipment that is used for tunneling mine working, engineering tunnel, city underground engineering, mainly is made up of walking mechanism, cutting mechanism, shipment activity and reprinting mechanism.Wherein cutting mechanism mainly comprises cutterhead and cut axle, and several picks are installed on the cutterhead, and cutterhead is connected with the cut axle.When development machine was worked, along with walking mechanism is pushed ahead, cutterhead was by cut axle driven rotary, continuous fractured rock, and the rock that is broken is by shipment activity and reprint mechanism and reprint, transport.According to cutterhead quantity difference, development machine can be divided into single cutterhead, two cutterhead two classes, wherein two cutterheads of two cut hair style development machines are installed on the two ends of cut axle respectively.
In the prior art, cutterhead with the cut axle generally adopt spline to be connected, but spline connects can not axial location, carry out axial location so also need to increase separately bolt, connecting link is more like this, complexity is installed, and is subjected to structural limitations, the connecting bolt number is less, and the axial load that causes the connecting portion potential energy to bear is less.
The utility model content
The technical problem that the utility model solves provides a kind of cutting mechanism that the simple and larger axis that can bear is installed to the development machine of load.
The cutting mechanism of development machine of the present utility model comprises cut axle and first cutterhead that is installed on cut axle one end, and described first cutterhead is connected by expansion coupling sleeve with described cut axle.
The cutting mechanism of development machine of the present utility model, wherein, the outer shroud that described expansion coupling sleeve comprises, interior ring, base ring, apical ring and cinch bolt, described outer shroud sidewall and described interior ring-side wall have first shrinkage joint and second shrinkage joint, described inner ring sleeve is on described cut axle, the outer wall of described outer shroud fits tightly with the inwall that is connected circular groove of described first cutterhead, the outer wall of described base ring and described apical ring comprises taper seat respectively, described base ring and described apical ring positioned opposite and all be clipped in outer shroud, between the interior ring, described cinch bolt passes apical ring and is threaded with base ring.
The cutting mechanism of development machine of the present utility model, wherein, described cinch bolt quantity is 12.
The cutting mechanism of development machine of the present utility model utilizes expansion coupling sleeve to replace original spline and bolt, utilize expansion coupling sleeve to connect first cutterhead and described cut axle, its mode is more simple, expansion coupling sleeve need not heat when mounted, cooling or pressurized equipment, cinch bolt moment on request need only be tightened and get final product, and easy to adjust.Expansion coupling sleeve is concentrated so can not produce stress because utilize frictional drive, and it is strong to bear the axial load ability.
Description of drawings
Fig. 1 is the structural representation of the cutting mechanism of development machine of the present utility model;
Fig. 2 is the left view of Fig. 1, shows the structure of the cutting mechanism that removes the development machine of the present utility model behind the baffle plate;
Fig. 3 is the A partial enlarged drawing of Fig. 1.
The specific embodiment
As shown in Figure 1, the cutting mechanism of development machine of the present utility model comprises cut axle 1, is installed on first cutterhead 2 and second cutterhead 3 at two ends, cut axle 1 left and right sides.
12 cinch bolts 5 pass apical ring 10 respectively and are threaded with base ring 9.When tightening cinch bolt 5, apical ring 10 and base ring 9 are axially strained, make the huge power of holding tightly of generation between interior ring 8 and the cut axle 1 by its taper seat separately, make between the inwall that is connected circular groove 21 of outer shroud 7 and first cutterhead 2 and produce tension force, realize the keyless joint of first cutterhead 2 and cut axle 1 thus.
For protection cut axle 1 left side, baffle plate 11 is installed at cut axle 1 left end.Baffle plate 11 is positioned at and connects circular groove 21, and by bolt on cut axle 1.
The above embodiment only is that preferred implementation of the present utility model is described; be not that scope of the present utility model is limited; under the prerequisite that does not break away from the utility model design spirit; various distortion and improvement that those of ordinary skills make the technical solution of the utility model all should fall in the definite protection domain of claims of the present utility model.
