Abstract
The utility model relates to a caterpillar crane walking device. A walking driving structure consists of a caterpillar board, a driving wheel, a thrust wheel, a guide wheel and chain sprockets; two serrated bosses in left and right symmetry are arranged on the caterpillar board; a force bearing face is arranged between the two bosses; the driving wheel, the thrust wheel, the guide wheel and the support sprockets are all provided with peripheral force bearing faces with projecting middle; the force bearing faces adapt to the caterpillar board; two side faces of the peripheral force bearing faces of each wheel are steering guide faces; grooves are evenly distributed on the symmetric peripheries of two sides of a body of the driving wheel; and the two serrated bosses of the caterpillar board are adapted to the grooves on two sides of the driving wheel body. The serrated bosses of the caterpillar board not only finishes transmission of driving force with the driving wheel grooves, but also has a bidirectional guide function, and symmetric grooves on two sides of the driving wheel lead the caterpillar board to be more even in force bearing. The caterpillar crane walking device leads a caterpillar crane to walk more steadily, solves the problem of running off of caterpillar in steering, obviously lowers transmission failure ratio, leads the caterpillar board to have more reasonable force bearing condition and longer service life, lowers maintenance cost, and increases production efficiency.
Description
One. technical field
The utility model relates to the running gear of crawler crane, is specifically related to a kind of running gear drive configuration.
Two. background technology
At present the walking device of crawler crane drive configuration that extensively adopts in the world has two kinds: a kind of is to be that the caterpillar block of representative has the side direction protrusion and drive wheel has tooth to be similar to " the wheel tooth plate is led " formula structure of chain sprocket drive with special rex De Mage company, groove in the middle of guide wheel, track carrying wheel and the caterpillar wheel turns to guidance force for crawler travel provides, its shortcoming is that two arc cam height are less in the middle of the caterpillar block, and band is taken off in walking easily when turning to.Another kind is to be single profile of tooth boss to be arranged in the middle of the caterpillar block of representative and drive wheel has " plate gear grooved " the formula structure that is alternately distributed groove with Liebherr company, groove in the middle of guide wheel, track carrying wheel and the caterpillar wheel turns to guidance force for crawler travel provides, its shortcoming is that drive wheel groove quantity is necessary for even number, when drive wheel and caterpillar block engagement, caterpillar block both sides discontinuity, damage easily, and drive wheel can only be realized the one-sided guiding that turns to.
Three. summary of the invention
The purpose of this utility model provides a kind of walking device of crawler crane, to solve the problem that tradition " plate gear grooved " formula and " the wheel tooth plate is led " formula drive configuration occur in actual applications, thereby the reduction maintenance cost is saved maintenance time, enhances productivity.
The technical solution adopted in the utility model is: the walking drive configuration of crawler crane is made of caterpillar block, drive wheel, caterpillar wheel, guide wheel and track carrying wheel, and two profile of tooth boss of left-right symmetric are arranged on the caterpillar block, is bearing area between two boss; Drive wheel, caterpillar wheel, guide wheel and track carrying wheel all have the circumference bearing area of the intermediate projections that adapts with caterpillar block, and each takes turns the two sides of circumference bearing area for turning to spigot surface; Drive wheel wheel body bilateral symmetry circumference uniform distribution groove, two the profile of tooth boss of caterpillar block and the groove of drive wheel wheel body both sides adapt.
The utility model also is a kind of " the plate gear is led " formula four-wheel one band drive configuration, groove uniform on profile of tooth boss on the caterpillar block and the drive wheel is meshed, the circumference bearing area of drive wheel is that transmission provides support power, and the double wedge side that drive wheel and other are respectively taken turns the spigot surface of bearing area both sides and caterpillar block provides support power when turning to.
The utility model is reasonable in design, is skillfully constructed.Can make the running gear operation more steady, the transmission fault rate obviously reduces, and improves the caterpillar block stressing conditions, and has solved the problem of taking off band when walking turns to, thereby reduces maintenance cost, saves maintenance time, enhances productivity.

Five. the specific embodiment
The walking drive configuration of crawler crane is made of caterpillar block, drive wheel, caterpillar wheel, guide wheel and track carrying wheel, two profile of tooth boss of left-right symmetric 1-1 is arranged above the caterpillar block 1, the flank of tooth is an engaged transmission usefulness, and two flank of tooth are inboard for turning to bearing area, and two boss mid-planes are bearing area 1-2; Drive wheel 2 wheel bodys adopt inblock cast, and there is symmetrical circumference uniform distribution groove 2-1 the wheel body both sides, and centre is protruding circumference bearing area 2-2, provides support power when drive wheel and caterpillar block engaged transmission, and the bearing area both sides are spigot surface, and guidance force is provided when turning to; Caterpillar wheel 3 solid forgings, the centre is single wide bearing area 3-1, two sides are for turning to spigot surface 3-2; Guide wheel 4 and track carrying wheel 5 all have circumference bearing area 4-2, the 5-2 of intermediate projections, and both sides are for turning to spigot surface 4-1,5-1.
The utility model is reasonable in design, has remedied the deficiency of tradition " plate gear grooved " formula and " the wheel tooth plate is led " formula structure, in actual applications, can reduce the transmission fault rate greatly, improve the caterpillar block stressing conditions, and operate steadily, do not take off band, be particularly suitable for crawler crane and use.
