Abstract
A cutting device of a tunneling machine is provided with a cutting arm and a cutting head articulated with a machine body. The front end of the cutting arm is provided with a sliding base and a sliding sleeve which are glidingly matched. The sliding base and the cutting arm are fixed, and an expansible driving oil cylinder is arranged between the sliding base and the sliding sleeve. The front part of the sliding sleeve is parallel articulated with two cutting heads with opposite rotation directions. Two swinging arms, opposite to the two cutting heads, are fixedly arranged. The sliding sleeve is internally provided with two parallel swinging arm driving cylinders connected with the two swinging arms. An articulation base is arranged between the cutting arms and the machine body. The articulation base is articulated with the machine body through a vertical shaft. A right-left swinging driving cylinder is arranged between the articulation base and the machine body. The cutting arms are articulated with the articulation base through a horizontal shaft. The lower part of the cutting arm is provided with a lifting driving cylinder. The cutting helix lines of the two cutting heads are designed in opposition along rotating directions, thus changing the opposite force generated in the working process of the machine into effective working force. Under the condition of using the equivalent power, the efficiency can be improved by 2.5 times to 4 times.
Description
Technical field
The utility model relates to the cutting means of mine heading equipments such as a kind of colliery, particularly a kind of development machine.
Background technology
The cutting means of original development machine has only list cutting arm only, after development machine needs cutterhead crept into rib at work, and cut about carrying out again or up and down.Up and down or about cutting process in, because the motive force of oscillating oil cylinder is bigger, makes the opposite force that forms between machine itself and the cutting arm uncontrollable, and causes entire machine in the course of the work, can be along with the swing of cutting arm, fuselage moves in the opposite direction.Work together and instability, inefficiency also brings great unsafe factor for safety in production.
Summary of the invention
The technical problems to be solved in the utility model is at the deficiencies in the prior art, proposed a kind of cut steadily, the cutting means of the development machine of high efficiency.
The technical problems to be solved in the utility model is achieved through the following technical solutions, a kind of cutting means of development machine, be provided with cutting arm and the cutterhead hinged with body, be characterized in: the front end of cutting arm is provided with slide and the sliding sleeve that is slidingly matched, slide and cutting arm are fixed, be provided with the telescopic drive oil cylinder between slide and the sliding sleeve, the front portion of sliding sleeve is hinged with two cutterheads that rotation direction is opposite side by side, with two cutterheads fixing in opposite directions be provided with two swing arms, in sliding sleeve, be provided with two swing arm driving oil cylinders that are connected with above-mentioned two swing arms respectively side by side.
The technical problems to be solved in the utility model can also come further to realize by the following technical programs, be provided with pivoting support between cutting arm and the body, pivoting support is hinged by vertical axis and body, be provided with the driving oil cylinder that swings between pivoting support and the body, cutting arm and pivoting support are hinged to axle by level, and being provided with the oscilaltion driving oil cylinder in the bottom of cutting arm, the oscilaltion driving oil cylinder is contained between cutting arm and the pivoting support.
The technical problems to be solved in the utility model can also come further to realize by the following technical programs, described cutting arm is provided with the cantilever of two interlocks side by side, slide and sliding sleeve are arranged between two cantilevers, and each cantilever has cover pivoting support, an oscilaltion driving oil cylinder respectively, driving oil cylinder swings.
The utility model discloses a kind of novel cutting means of development machine, it is provided with two hinge joint link-type cutterheads side by side, when rib is crept into, in order to improve the stability of work, the cut helical design of two cutterheads is that rotation direction is opposite, the opposite direction power that machine is taken place in the course of the work becomes effective operational forces, and it is increased work efficiency.Compared with prior art, under situation about using with constant power, its efficient can improve 2.5-4 doubly.
Description of drawings
Fig. 1 is a plan structure sketch of the present utility model.
Fig. 2 is the working state figure of development machine.
The specific embodiment
A kind of cutting means of development machine, be provided with cutting arm 11 and the cutterhead hinged with body, the front end of cutting arm 11 is provided with slide 12 and the sliding sleeve 8 that is slidingly matched, slide 12 is fixing with cutting arm 11, be provided with telescopic drive oil cylinder 7 between slide 12 and the sliding sleeve 8, the front portion of sliding sleeve 8 is hinged with two cutterheads 1,2 that rotation direction is opposite side by side, with two cutterheads 1,2 fixing in opposite directions be provided with two swing arms 3,4, in sliding sleeve 8, be provided with two swing arm driving oil cylinders 5,6 that are connected with above-mentioned two swing arms respectively side by side.
Described cutting arm 11 is provided with the cantilever of two interlocks side by side, and slide 12 and sliding sleeve 8 are arranged between two cantilevers.Be provided with pivoting support 10 between cantilever and the body, pivoting support 10 is hinged by vertical axis and body, be provided with the driving oil cylinder 9 that swings between pivoting support 10 and the body, cantilever and pivoting support 10 are hinged to axle by level, and being provided with oscilaltion driving oil cylinder 13 in the bottom of cantilever, oscilaltion driving oil cylinder 13 is contained between cantilever and the pivoting support 10.When cutting arm 11 swung under the driving oil cylinder 9 that swings drives, two cutterheads can parallel motion.
Two cutterhead 1,2 rotation directions are opposite, and both rotate when work in opposite directions, thereby can offset because the instability that rotation brings.After cutterhead creeps into, shovel board stretching ground, whole device begins to move up and down under the effect of oscilaltion driving oil cylinder 13, can move the swing arm driving oil cylinder simultaneously and make two cutterheads 1,2 move the operating efficiency that makes its performance maximum simultaneously laterally or to the inside.The characteristics that this device improves complete machine stability are as follows: rotated in opposite directions by two cutterheads when cutterhead creeps into; Two cutterheads have action inside simultaneously, outer folding; When shovel board stretching ground, do the cut vertical motion.More than action all can be cancelled out each other no worker's reaction force.
