Description
Technical field
The utility model relates to a kind of tensioning buffer gear, particularly a kind of track takeup that is applied to the endless track installation on small crawler construction machinery and equipment and the field machine.
Background technology
Crawler type walking mechanism traction tack is good, and grounding pressure is little, is widely used on construction machinery and equipment and field machine.Its structure of crawler type walking mechanism generally is provided with drive wheel and a plurality of caterpillar wheel on walker; crawler belt is looped around on drive wheel and a plurality of caterpillar wheel; therefore crawler type walking mechanism just has the problem of a crawler tensioning and buffering; the crawler tensioning shock absorber generally all is housed in creeper undercarriage; guarantee that crawler belt has suitable tensile force, make crawler belt can not occur being with bounce or taking off zoning, buffer action is arranged when making vehicle run into obstacle in enforcement; reduce and impact, protection vehicle and crawler belt.
At present, the tensioning shock absorber of endless track installation has two kinds of forms: the one, adopt high version of putting drive wheel at the creeper undercarriage of small engineering machinery such as most crawler type glide steering loaders and field machine, the tightening device of this traveling gear normally by preceding guide wheel under the effect of spring, directly crawler tensioning, this mode is simple, but when machine is crossed obstacles such as stone in the driving process on broken terrain, before guide wheel be subjected to the impact of obstacle and move after overcoming the application force of spring, though spring has played the effect of buffering, but this moment is owing to move behind the preceding guide wheel, make crawler belt and drive wheel, the cornerite of preceding guide wheel and back guide wheel diminishes, like this, crawler belt under the pretension state fluffs suddenly, and this moment, crawler belt can be than being easier to take place to jump tooth, take off zoning.Especially for small-sized caterpillar belt formula vehicle because small-sized caterpillar belt formula vehicle adopts rubber belt track mostly, and because the crawler belt joint number is less, jump tooth, the phenomenon of taking off band can be more serious.
The 2nd, on the creeper undercarriage employing drive wheel direct contact ground of some small-sized caterpillar belt formula vehicles, drive wheel plays a part the back caterpillar wheel when playing the active force effect, this is the traveling gear form that present nearly all traxcavator all uses.Because drive wheel directly rolls on the ground, is subjected to the wearing and tearing of mud, sand, stone easily, it is bigger to be subjected to the ram ratio that transmits on ground simultaneously, and because the bogie frame easy deformation, thereby influences the engagement of crawler belt.In addition, the tightening device of this traveling gear also be usually by preceding guide wheel under the effect of spring or hydraulic ram, directly crawler tensioning, therefore, also than the phenomenon that is easier to occur jump tooth, take off band.And generally to the processing request of inside and outside sliding guide all than higher, the processing technology complexity, than higher, manufacture difficulty is also bigger to the requirement of Fabricating machinery, quality control is difficult, the while, cost was also than higher.
In order to solve the problem of crawler tensioning, Chinese patent literature discloses a kind of tensioning problem of creeper undercarriage, the patent No. of the document is " ZL200720064813.2 ", name is called " tightening device of crawler type walking mechanism ", this device comprises walker, first bogie wheel, second bogie wheel, described walker and first connecting rod, second connecting rod and third connecting rod are formed four-bar linkage, described first bogie wheel is installed on the hinge of described first connecting rod and second connecting rod, described second bogie wheel is installed on the hinge of described second connecting rod and third connecting rod, length adjustment bar one end and described walker are hinged, and the other end and described third connecting rod are hinged.The track takeup of this structure can be realized bigger contraction scope, help the installation and removal of crawler belt, but tension effects is relatively poor, the phenomenon of occur the jumping tooth easily, taking off band, and the effect that does not have buffering.
The utility model content
The purpose of this utility model provides a kind of tensioning shock absorber that can conveniently be applied to the endless track installation on small engineering machineries such as crawler type glide steering loader and the field machine, this device can not only prevent effectively that crawler belt from the band bounce occurring or taking off band, and simple in structure, convenient processing and manufacture, with low cost, be convenient to install and dismounting.
In order to solve the problems of the technologies described above, the tensioning shock absorber of the utility model endless track installation, comprise walker, guiding wheel carrier, connecting rod, shock absorber, guide wheel, tension wheel, wherein, described guiding wheel carrier, connecting rod constitute fixed triangle mechanism by set pin, one end of described guiding wheel carrier and the front end of described walker flexibly connect, one end of the other end and guide wheel and connecting rod flexibly connects, one end of the other end of described connecting rod and described shock absorber and tension wheel flexibly connect, and the other end of described shock absorber and described walker flexibly connect.
The tensioning shock absorber of above-mentioned endless track installation, wherein, described shock absorber comprises the slider waveguide rod device, and spring, described slider waveguide rod device comprise the slide block that links to each other with connecting rod, the guide rod that links to each other with walker, and described slide block matches with described guide rod; Described spring housing is in the periphery of described guide rod, and described spring one end is resisted against the outside of described slide block, and the other end is against on the bottom surface of described guide rod.
The tensioning shock absorber of above-mentioned endless track installation, wherein, described guide rod is adjustable guide rod, comprises guide rod body, sleeve, and the described sleeve of an end of described guide rod body is by being threaded, and the other end is hinged on the upside of described walker by bearing pin; The other end of described sleeve inserts described slide block and cooperates with described space of slider.
Adopt the tensioning shock absorber of the endless track installation of said structure, described guiding wheel carrier, connecting rod constitute fixed triangle mechanism by set pin, wherein, the guiding wheel carrier is that the center is rotated with guiding wheel carrier and walker point of connection, thereby drives tension wheel, guide wheel is that the center freely swings up and down to guide wheel carrier and walker point of connection.When in crawler belt is advancing process, running into obstacles such as stone piece, guide wheel is by the certain angle of left-hand revolution, make upwards swing of tension wheel by connecting rod, thereby strengthened the through performance of machine greatly, simultaneously, in the process that the connecting rod of cam mechanism is upwards swung, because the position of tension wheel is from the past high-order motion of low level, the tensioning degree that has guaranteed crawler belt remains on original pretension state substantially, thereby has prevented the generation that crawler belt causes the crawler belt bounce or takes off band because of fluffing effectively; And because described shock absorber is slider waveguide rod device and spring, use more convenient and can reduce the volume of tensioning shock absorber, when guide wheel was subjected to impacting, the impact that guide wheel can be transmitted from ground directly cushioned through tension wheel, thereby realized the effect of buffering; Simultaneously,, use more conveniently, and can make things convenient for the installation of crawler belt because described guide rod is adjustable guide rod.
