This patent discloses a kind of cutting head Folding device of concrete cutting machine, with the cutting head on the folding cutting machine when carrying.Comprise frame, hinged in frame telescopic cylinder is installed, telescopic cylinder can its rear end be that fulcrum is around gantry rotation, the below of frame is also hinged with fork, the free end of fork is provided with cutting head, the piston rod of telescopic cylinder is connected by first connecting rod and second connecting rod with the stage casing of fork, the stage casing of first connecting rod is hinged in frame, the drive end of first connecting rod and the free end of piston rod hinged, the driven end of first connecting rod and the drive end of second connecting rod hinged, the driven end of second connecting rod is hinged on the stage casing of fork.When needing folding cutting head, the protruding LAP of piston rod of telescopic cylinder, first connecting rod and second connecting rod folding at an angle, fork is pulled upwardly simultaneously, make, in the cutting head income frame on fork, to ensure that the use flexibility of whole device.
Description
Technical field
The utility model relates to a kind of concrete cutting machine.
Background technology
" concrete cutting " refers to the construction technology that instruments such as adopting the mechanical, electrical dynamic dish saw of Hydraulic saw for wall, water drilling or road cutting machine cuts concrete component, body of wall, road surface etc., it is strong that it has cutting power, and static(al) can't harm, and efficiency is high, adopt water cooling, without features such as construction dust.
The seam of concrete road surface cutting is called ' contracting seam '.Concrete coagulation hardening process, hydrated cementitious will discharge amount of heat, causes concrete temperature to raise; Major part hydrated reaction of cement terminates, and concrete temperature starts to decline.At temperature-fall period, concrete is setting and harden, and the contraction that cooling produces can cause concrete cracking, and fractuer direction is relatively more random, has a strong impact on pavement quality and service life.
Therefore, general after concreting 8 ~ 12 hours (must before concrete road surface temperature starts to reduce), spacing 4 ~ 6 meters will cut contracting seam, and depth of cut is about 1/3rd of road deck thickness, inducing concrete contraction fissure can produce along cutting seam like this, prevent stochastic crack.Then, pavement contraction joint wants asphalt reperfusion or fluid sealant to seal, and prevents rainwater snow-broth from entering roadbed.
The cutting blade that cutting head on cutting machine connects operationally needs to go deep into below ground, to cut concrete road surface.After completing in work, the cutting blade stretched out downwards can cause inconvenience to a certain degree to the carrying of cutting machine again.
Utility model content
The utility model is intended to the cutting head Folding device providing a kind of concrete cutting machine, with the cutting head on the folding cutting machine when carrying.
The cutting head Folding device of the concrete cutting machine in this programme, comprise frame, hinged in frame telescopic cylinder is installed, telescopic cylinder can its rear end be that fulcrum is around gantry rotation, the below of frame is also hinged with fork, the free end of fork is provided with cutting head, the piston rod of telescopic cylinder is connected by first connecting rod and second connecting rod with the stage casing of fork, the stage casing of first connecting rod is hinged in frame, the drive end of first connecting rod and the free end of piston rod hinged, the driven end of first connecting rod and the drive end of second connecting rod hinged, the driven end of second connecting rod is hinged on the stage casing of fork.
When cutting machine works, the piston rod of telescopic cylinder is inwardly retracted and is kept less and stretch out stroke, now first connecting rod and second connecting rod are straight line, drive fork to make it to keep straight down simultaneously, cutting head on fork can start work, and because first connecting rod and second connecting rod are straight line, whole bar linkage structure is in dead point, the impulsive force produced fork during cutting can not make fork produce swinging deformation, ensure that the stable of work.When needing folding cutting head, the protruding LAP of piston rod of telescopic cylinder, first connecting rod and second connecting rod folding at an angle, fork is pulled upwardly simultaneously, make, in the cutting head income frame on fork, to ensure that the use flexibility of whole device.
Further, when the piston rod of telescopic cylinder extend out to range, fork is level.Larger folding space can be ensured.
Further, when the piston rod of telescopic cylinder is retracted to minimum stroke, first connecting rod and second connecting rod coaxial.Stability during duty can be ensured.
Further, the expose portion of piston rod is provided with dust cover.To avoid impurity interference during work.
Accompanying drawing explanation
Fig. 1 is the structural representation of the utility model embodiment.
Detailed description of the invention
Below by detailed description of the invention, the utility model is described in further detail:
Reference numeral in Figure of description comprises: telescopic cylinder 1, piston rod 2, first connecting rod 3, second connecting rod 4, fork 5, cutting head 6.
Embodiment is substantially as shown in Figure 1: the rear end of the left part of telescopic cylinder is hinged in frame, and its initial position is substantially in being horizontally disposed with.Telescopic cylinder can its rear end be fulcrum around gantry rotation, the expose portion of piston rod is provided with dust cover (not shown).
The below of frame is also hinged with fork, and fork can swing in the 4th interval range in the drawings, and the free end below fork connects cutting head.
Right-hand member and the first connecting rod drive end of piston rod are hinged, and the stage casing of first connecting rod is hinged in frame, second connecting rod float arrange with frame in, the driven end of first connecting rod and the drive end of second connecting rod hinged, the driven end of second connecting rod is hinged on the stage casing of fork.
When cutting machine works, the piston rod of telescopic cylinder is retracted to minimum stroke, now first connecting rod and second connecting rod are straight line, drive fork to make it to keep straight down simultaneously, cutting head on fork can start work, and because first connecting rod and second connecting rod are straight line, whole bar linkage structure is in dead point, the impulsive force produced fork during cutting can not make fork produce swinging deformation, ensure that the stable of work.When needing folding cutting head, the piston rod of telescopic cylinder extend out to range, first connecting rod and second connecting rod folding at an angle, fork is pulled upwardly simultaneously, make the cutting head on fork be level income frame in.
Above-described is only embodiment of the present utility model, and in scheme, the general knowledge such as known concrete structure and characteristic does not do too much description at this.Should be understood that; for a person skilled in the art, under the prerequisite not departing from the utility model structure, some distortion and improvement can also be made; these also should be considered as protection domain of the present utility model, and these all can not affect effect and the practical applicability of the utility model enforcement.The protection domain that this application claims should be as the criterion with the content of its claim, and the detailed description of the invention in description etc. record the content that may be used for explaining claim.
