Mouth (not shown) projects in the first slide rail 401 and the second slide rail 402.When the first slide block 501 and
Two slide blocks 502 on the first slide rail 401 and tail end from the second slide rail 402 to fuselage 101 slide time, institute
State ratchet to retract under the pressure effect of described slide block, when described slide block crosses described ratchet,
Described ratchet can project into again the first slide rail 401 and the second slide rail 402 under the elastic force effect of leaf spring
In, stop slide block back to move, thus lock described slide block position on slide rail.When described cunning
Block needs back to move-time i.e. direction along Fig. 8 moves up, other actuators-such as can be passed through
Electromagnetic valve or motor or hydraulic motor overcome the elastic force of leaf spring, so that ratchet is inwardly retracted also
Therefore slide block is made successfully to slide to the front end of fuselage 101.About this point, it should be pointed out that
Described ratchet lock mechanism is merely to illustrate that problem and the exemplary mechanisms enumerated.Without departing from
In the case of the principle of the present invention, those skilled in the art can also use other locking mechanisms, this
Without departing from protection scope of the present invention.
In conjunction with construction described above, skilled addressee readily understands that, first
The length of hydraulic cylinder the 201, second hydraulic cylinder the 202, the 3rd hydraulic cylinder 203 and the 4th hydraulic cylinder 204 can
The size of the hydraulic coupling being applied to them by change regulates.With the position of Fig. 2 as starting point, when adopting
Coal machine 1 needs to move forward-time i.e. paper direction along Fig. 2 and 3 moves up, it is not necessary to change the
One bearing 301 and second bearing 302 Support Position on the sidewall 12 and 13 of coal mine roadway,
And have only to moving and make the first slide block 501 and the second slide block 502 with coal-winning machine 1 and fuselage 101 thereof
Slide backward in the first slide rail 401 and the second slide rail 402 respectively, reduce hydraulic coupling so that institute simultaneously
State hydraulic cylinder 201,202,203 and 204 shrink and therefore adapt to coal-winning machine 1 move the described liquid caused
Distance change between fulcrum and described the strong point being seated against on coal mine roadway sidewall of cylinder pressure.
As it has been described above, when coal-winning machine 1 moves to target location, above-mentioned locking mechanism 4012 He can be passed through
4022 fix its position and therefore re-form triangular support configurations.As can be seen here, when using this
During bright supporting construction, it is not necessary to the most again find when the most mobile coal-winning machine 1 described bearing
Support position, decreases operation related to this and therefore saves the time, improve working performance.
Although describing technical scheme with reference to preferred implementation, but this
Skilled person is it is easily understood that protection scope of the present invention is not limited to these specifically in fact
Execute mode, in the case of without departing from the ultimate principle of the present invention, can to described embodiment with
And concrete technical characteristic therein carries out splitting, combine or changing, after splitting, combine or changing
Technical scheme will fall under the scope of the present invention.
