The specific embodiment
Below in conjunction with drawings and Examples the utility model is further specified.
Among Fig. 1,2,3, shrinkage joint, a kind of concrete slope cutting machine comprises the track support 1 that is consistent with face of land shape, and track support 1 is provided with can be along its joint-cutting device that moves, the joint-cutting device is connected with haulage gear on being located at track support 1, and the joint-cutting device is provided with knocks groove mechanism.
Described track support 1 is connected to form by two parallel orbits, and two track bottoms are provided with folding roller 6.
Described joint-cutting device comprises the dolly 2 that is arranged on the track support 1, and dolly 2 bottoms are provided with and are stuck on the track and the wheel 3 of track-movable, and dolly 2 is provided with cutting machine 4, and the cutting blade 5 on the cutting machine 4 is positioned at track support 1 one sides.
Described haulage gear comprises buncher 8 and the hoist engine on the base 7 that is arranged at belt wheel 9, the output shaft of buncher 8 links to each other with the reducer of hoist engine 25, be provided with clutch 11 between the reducer 25 on the hoist engine and the reel 10 of hoist engine, the other end of reel 10 is provided with armstrong's patent band-type brake 12; Base 7 is connected in track support 1 upper end by spring 13, base 7 links to each other with track support 1 to hold and is provided with a gear 14, gear 14 is provided with coaxial Hall element 15, base 7 is provided with and Hall element 15 corresponding magnet 26, Hall element 25 is connected by the speed setting controller of circuit with buncher 8, and gear 14 is meshed with the tooth bar 17 of the position-adjustable that is arranged at track support 1 front end.Armstrong's patent band-type brake 12 is existing apparatus, can buy on market, does not repeat them here.
The described groove mechanism of knocking comprises hammering block 18, hammering block 18 mid portions are enclosed within the sleeve 19 that is arranged on the cutting machine 4, sleeve 19 can be with respect to the ground adjusting angle, be respectively equipped with block 20 on the hammering block 18 of sleeve 19 both sides, be provided with back-moving spring 21 between the upper end block 20 of hammering block 18 and the sleeve 29, hammering block 18 top corresponding cutting machines 4 are provided with reciprocal knocking device.
Back and forth knocking device comprises that an end is articulated in and knocks piece 22 on the cutting machine 4, knocking the other end of piece 22 matches with cam 23 on being arranged at cutting machine 4, knock piece 22 be provided with one with hammering block 18 returning spring 24 in the same way, returning spring 24 other ends are arranged on the cutting machine 4, and cam 23 is connected with the cutting machine power set by power transmission shaft.
The utility model rotates by the hoist engine motor, after slowing down, dragging cutting machine 4 by wire rope goes up a slope and cutting, because pulling force is to act between base 7 and the cutting machine 4 by spring 13, like this when hoist engine changes to the pulling force of cutting machine 4, the pulled out condition of spring 13 can change, this variation can make between tooth bar 17 and the gear 14 relative motion takes place, and then gear 14 is rotated, and drive coaxial Hall element 25 and rotate, the output signal of Hall element 25 passes to the speed setting controller of buncher 8 like this, and then the speed of hoist engine motor is changed, the cutting blade that guarantees cutting machine 4 is subjected to the metastable power of size (size of power can be adjusted by the front and back position of adjusting tooth bar 17) always, avoid making cutting machine 4 work in unreasonable state too greatly or too little, realize that the imitation people pushes away the mode of cutting machine work because of cutter system is stressed.
In cutting process, if the ground material is loose relatively, cutting machine 4 runnings easily, the advance resistance of cutting machine 4 diminishes, and the spring 13 between base 7 and the track support 1 shrinks, and the relative position of tooth bar 17 and gear 14 changes, gear 14 is rotated counterclockwise, drive coupled Hall element 25 simultaneously and rotate counterclockwise, Hall element 25 passes the signal along to electric machine controller by circuit, and control hoist engine motor revs up.
If the ground material is harder, or other reasons, cause cutting machine 4 rotating speeds slack-off, and then make its gait of march slack-off, and the spring 13 between base 7 and the track support 1 is stretched elongated, and the relative position of tooth bar 17 and gear 14 changes, gear 14 is clockwise rotated, drive coupled Hall element 25 simultaneously and clockwise rotate, Hall element 25 passes the signal along to electric machine controller by circuit, and control hoist engine motor reduces rotating speed.
If former thereby make the stuck situation of cutting machine 4 because of certain, at this moment cutting machine 4 no longer up moves, and greatly when a certain amount of, controller control hoist engine motor shuts down hoist engine to its pulling force.
When cutting machine 4 used two cutting blades 5 cutting sipes, the reciprocating motion of hammering block that can be by knocking groove mechanism knocked out the concrete block between two joint-cuttings automatically.
When cutting machine 4 reaches when top slope, when needing whole shift position, the roller 6 of track support 1 bottom is got out, can arrive correct position by the move left and right package unit.
Because the speed of service is slower during cutting machine 4 cuttings, lifting drum is in the ultra low speed operation state equally, and buncher should run on the middling speed state, very large speed reducing ratio is just arranged between buncher and the lifting drum like this, when cutting machine 4 reaches the top, slope, reel 10 is separated with hoist engine reducer 25 with clutch 11 between the reel 10 by hoist engine reducer 25, allow the joint-cutting device glide with fast speed along track, can Cutting Control machine 4 gliding speeds by armstrong's patent band-type brake 12, avoid meeting accident.
