Alternatively, referring to fig. 3 and 6, the two ends of the first movable beam 13 and the bottom plate 11, and the two ends of the second movable beam 14 and the bottom plate 11 are connected by the second pin 16. The bottom of bottom plate 11 is provided with the mounting panel, and the both ends of first walking beam 13 and second walking beam 14 all are provided with the pinhole, and second round pin axle 16 runs through mounting panel and pinhole to realize dismantling between first walking beam 13 and second walking beam 14 and the bottom plate 11 and be connected, the later stage of being convenient for is maintained sled. Further, the first movable beam 13 and the second movable beam 14 have the same structure, can be used interchangeably, and are convenient to machine and maintain.
As shown in fig. 3 and 8, a rear pulling part 61 is optionally provided on the second support beam 6, and the rear pulling part 61 is configured to be connected to the next ski. When a plurality of sleds are required to be used, the rear traction part 61 and the connecting ring 4112 of the traction base 411 of the next sled can be connected by using a steel wire rope, so that the plurality of sleds can be ensured to run consistently.
Fig. 8 shows a schematic view of the turning of the ski, when the traction device turns, the traction device drives the traction frame 41, the first ski foot 21 and the second ski foot 22 to turn, the third ski foot 31 and the fourth ski foot 32 move synchronously under the traction force of the third chain 423, and the first support beam 5 and the second support beam 6 also turn along with the first ski foot 21, the second ski foot 22 and the third ski foot 31 and the fourth ski foot 32. Due to the existence of the first pin shaft 15, the first movable beam 13 rotates relative to the first supporting beam 5, and the second movable beam 14 rotates relative to the second supporting beam 6, so that the object carrier 1 and the goods to be transported thereon can slowly turn at a constant speed, the object carrier 1 is prevented from inclining due to the inertia effect, and the integral stability of the sledge operation is further ensured.
The sled provided by the embodiment can normally work at the environment temperature of minus 40 ℃; the bearable maximum working wind pressure is 600N/m 2 (ii) a The vehicle can normally run on a road with the gradient less than or equal to 15 degrees; the steering angle range of more than or equal to 20 degrees can realize flexible steering, and the steering device can be well suitable for severe environments in polar regions.
