Detailed description of the invention: detailed description of the invention of the present utility model is, with reference to Fig. 1, Fig. 2, comprise height adjustment mechanism and stop gear, described stop gear comprises heart-shaped limit body fixed mount 4, heart-shaped limit body 3, Y shape support arm 1, allotment arm 2, spacing jointed shaft 8, Y shape support arm jointed shaft 9 and allotment arm jointed shaft 5, wherein, described heart-shaped limit body fixed mount 4 connects heart-shaped limit body 3, described heart-shaped limit body 3 coordinates with the profiling of spacing jointed shaft 8, the hinged Y shape support arm 1 of described spacing jointed shaft 8 and allotment arm 2 one end, described Y shape support arm 1 and the other end of allotment arm 2 and Y shape support arm jointed shaft 9 and allotment arm jointed shaft 5 hinged, described Y shape support arm jointed shaft 9 and allotment arm jointed shaft 5 and two arms 7 of drawing money on credit in height adjustment mechanism, 6 connect, described heart-shaped limit body fixed mount 4 is connected with vehicle pontic,
With reference to Fig. 3, Fig. 4, described heart-shaped limit body 3 has the profiling track groove 11 coordinated with described spacing jointed shaft 8, there is the unthreaded hole 10,12,13,14 coordinated with described heart-shaped limit body fixed mount 4 both sides of described profiling track groove 11;
With reference to Fig. 7, Fig. 8, described Y shape support arm 1 comprises main support arm 18 and two articulated jibs 19,22, described main support arm 18 and two articulated jibs 19,22 are integrated, described main support arm 18 there is the hinge hole 17 hinged with Y shape support arm jointed shaft 1, described two articulated jibs 19,22 have the hinged unthreaded hole 20,21 hinged with spacing jointed shaft 8;
With reference to Fig. 5, Fig. 6, described allotment arm 2 is rectangle, and there is the hinged unthreaded hole 15,16 coordinated with described allotment arm jointed shaft 5 at the two ends of described allotment arm 2;
The principle of work of this height-adjustable cterpillar drive locked mechanism is: when needs normal operation height, after hydraulic stem in hydraulic ram stretches out cylinder body, two short articulated brackets are subject to two outside application forces, due to two band andgudgeon extension bar two ends, two short articulated bracket two ends respectively with gear shaft, it is all articulated structure that two action-oriented wheel shafts and two determine guide wheel shaft, therefore, under the effect of hydraulic ram, height adjustment mechanism produces diamonding, two action-oriented wheels are to hydraulic ram two end motion, two support arm shafts be connected with two band andgudgeon extension bars are along with two band andgudgeon extension bars are to moving near crawler belt direction, spacing jointed shaft 8 moves to wide end in profiling track groove 11, until to normal operating altitude, when needs raise operation height, hydraulic stem in hydraulic ram reclaims in cylinder body, two short articulated brackets are subject to two inside application forces, due to two band andgudgeon extension bar two ends, two short articulated bracket two ends respectively with gear shaft, it is all articulated structure that two action-oriented wheel shafts and two determine guide wheel shaft, therefore, under the effect of hydraulic ram, height adjustment mechanism produces triangle deformation, two support arm shafts be connected with two band andgudgeon extension bars move to away from crawler belt direction along with two band andgudgeon extension bars, spacing jointed shaft 8 moves to narrow end in profiling track groove 11, till reaching suitable operation height, along with the continuous adjustment of operation height, spacing jointed shaft 8 can move up and down in heart-shaped limit body 3, after height-adjustable cterpillar drive completes triangle deformation, spacing jointed shaft 8 is limited to the narrow end of heart-shaped limit body 3, ensure that the swing of height adjustment mechanism hinge gap is in rational amplitude, this height-adjustable cterpillar drive advanced or backing resistance time, driving gear axle gravity vertical remains in two positions of determining between track adjusting wheel, this makes this height-adjustable cterpillar drive when running into section, special field, can not be high because of center of gravity, center of gravity easily offsets, and there is the phenomenon that car body topples.
