Detailed Description

The present invention will be described in further detail with reference to the accompanying drawings.

As shown in figure 1, the special-shaped crawler traveling device comprises two device bodies symmetrically arranged below a vehicle body, each device body comprises a base frame 1 fixedly connected with the vehicle body, a plurality of thrust wheels 2 are arranged below the base frame 1 at intervals, a gap for the thrust wheels 2 to rotate is formed between each thrust wheel 2 and the base frame, and the shape and the size of the plurality of thrust wheels 2 are completely the same. A support frame 3 is further arranged above the base frame 1, and the support frame 3 is located at the front end of the base frame 1.

As shown in fig. 1, the supporting frame 3 includes a pair of supporting rods 31, the lower ends of the pair of supporting rods 31 are far away from each other, the upper ends of the pair of supporting rods 31 are close to each other, a driving wheel 4 is rotatably connected above the pair of supporting rods 31, and the driving wheel 4 is connected with a driving axle of an original vehicle through a connecting disc to provide power for the device. The drive axle is the existing structure of the crawler, and can refer to a crawler tractor disclosed in the Chinese patent with the publication number of CN 107531293A.

As shown in figure 1, the driving wheel 4 is provided with the same rubber track 5 matched with the outer wall of the thrust wheel 2, a plurality of block-shaped anti-skid patterns 51 are arranged on the outer surface of the rubber track 5, and a groove 52 is formed between every two adjacent anti-skid patterns 51.

When the above-described special-shaped crawler travel unit is applied to a vehicle, the drive wheel 4 is directly connected to the drive axle of the original vehicle. When the vehicle works, the driving wheel 4 is driven to rotate, and the rubber crawler 5 is continuously driven to roll and lay from back to front by the matching of the driving wheel 4 and the thrust wheel 2. The driving force of the driving wheel 4 is transmitted to the plurality of track rollers 2 through the rubber crawler 5 to act on the road surface, so that the road surface generates a reaction force acting on the contact crawler, thereby driving the vehicle to normally travel by means of the reaction force of the rubber crawler 5 acting on the contact crawler while performing a winding motion.

Because the driving wheel 4 is directly connected with the driving axle of the original vehicle, and the driving wheel 4 and the thrust wheel 2 are not on the same horizontal line; therefore, under the same operation condition, since the diameter of the driving wheel 4 is smaller than the tire diameter of the original vehicle, the running speed of the vehicle with the crawler traveling apparatus is lower than that of the original vehicle with the tire. The maximum traction capacity of the tractor is improved compared with that of the original vehicle, so that the tractor greatly improves the traction capacity and can smoothly pass through the severe environments such as a slope, a trench, a vertical obstacle and the like.

As shown in fig. 1, a guide wheel 11 is disposed on the upper end surface of the base frame 1, and a gap for the guide wheel to rotate is formed between the guide wheel 11 and the base frame 1. The guide wheel 11 is positioned at the front end of the base frame 1 and is abutted against the inner wall of the rubber crawler 5, and the rubber crawler 5 between the guide wheel 11 and the thrust wheel 2 at the most front end is in a vertical state.

Because the rubber crawler 5 at the position of the thrust wheel 2 located at the foremost end contacts the ground first when the rubber crawler 5 travels forward. Therefore, the guide wheels 11 are arranged to guide the front end of the rubber crawler 5, so that the rubber crawler 5 at the position is in a vertical state, the applied force is perpendicular to the ground, the ground gripping force of the rubber crawler 5 is improved, the traction capacity of the rubber crawler 5 is improved, and the rubber crawler can smoothly pass through severe environments such as trenches and vertical obstacles.

As shown in fig. 1 and 2, a supporting seat 6 is horizontally slidably connected to one end of the base frame 1 away from the guide wheel 11, a tension wheel 61 abutting against the inner wall of the rubber crawler 5 is disposed at one end of the supporting seat 6 away from the guide wheel 11, and a driving mechanism 7 for driving the supporting seat 6 to slide back and forth is disposed on the base frame 1.

When a vehicle with the special-shaped crawler belt walking device runs, a certain pretensioning force is provided for the rubber crawler belt 5 by arranging the position-adjustable tensioning wheel 61, so that the tensioning force of the rubber crawler belt 5 is increased, and the rubber crawler belt 5 is prevented from being disengaged from the wheel. And when the bicycle runs, the tension wheel 61 also plays a certain load-bearing role, so that the load burden of the driving wheel 4 and the supporting wheel 2 is reduced, and the stress at each position is more uniform.

As shown in fig. 1 and 2, edge plates 62 are horizontally disposed on both sides of the support base 6, strip-shaped holes 63 are formed in the edge plates 62 along the length direction of the edge plates, a pair of bolts 64 are disposed on the edge plates 62, and the bolts 64 are threaded into the base frame 1 after passing through the strip-shaped holes 63.

When the tension of the tension wheel 61 needs to be adjusted, the bolt 64 is loosened, and then the support seat 6 is driven to slide forwards or backwards by the driving mechanism 7. At this time, the supporting seat 6 drives the tensioning wheel 61 to move synchronously, and the tensioning force of the rubber track 5 is adjusted. After the tension of the rubber track 5 is adjusted, the bolt 64 is screwed, and the edge plate 62 is pressed and fixed on the base frame 1 by the bolt 64, so that the whole support seat 6 is locked and fixed.

As shown in fig. 1 and 2, the driving mechanism 7 includes a driving seat 71 vertically disposed on the base frame 1, a threaded hole 72 penetrates through the driving seat 71, a screw rod 73 is horizontally and threadedly connected in the threaded hole 72, and one end of the screw rod 73 close to the supporting seat 6 is rotatably connected to a side wall of the supporting seat 6.

When the driving mechanism 7 is used for controlling the support seat 6 to slide, the screw 73 is driven to rotate by a wrench or an electric wrench, at this time, the screw 73 is close to or away from the tensioning wheel 61, and simultaneously, the screw 73 drives the support seat 6 and the tensioning wheel 61 to move synchronously, so that the tensioning force of the rubber track 5 can be adjusted by the tensioning wheel 61.
