Sled

Abstract

The invention relates to the technical field of snowfield transportation equipment, and discloses a sled. A large container and a large passenger compartment can be placed on a carrier; traction equipment pulls a first walking assembly and a second walking assembly to slide on the ground through a traction frame and a traction chain assembly, so that transportation of large goods is achieved, and the problem that in the prior art, a large-size container and a large-size passenger compartment are difficult to transport is solved. The first walking assembly and the second walking assembly are both detachably connected with the carrier, the traction chain assembly and the traction frame are detachably connected, the traction chain assembly and the second walking assembly are also detachably connected, and if faults occur, parts of the sled can be replaced at any time, so that maintenance is convenient, and it can be guaranteed that inspection tasks are normally conducted. When the sled steers, due to the fact that the carrier can rotate relative to the first walking assembly and the second walking assembly, the carrier and the goods to be transported on the carrier can steer slowly, so that the carrier is prevented from toppling due to the inertia force effect when the sled steers.

Description

technical field [0001] The invention relates to the technical field of snow transportation equipment, in particular to a sled. Background technique [0002] With the development of our country's polar expeditions, large sleds have become an indispensable means of transportation in polar transportation. It shoulders important tasks such as transporting scientific research materials and carrying crew cabins during polar inland expeditions. Materials are mainly packed in containers, which are placed on sleds, and the sleds are moved by traction by snow tractors, etc. Multiple sleds can be connected in series with wire ropes, and the same snow tractor can be used for traction. [0003] At present, the commonly used sleds are mainly standard Antarctic sleds. The existing standard sleds have problems such as single type, heavy weight, difficult maintenance, easy wear, high maintenance cost and short service life. Moreover, the standard sled cannot meet the transportation of large...

AI Technical Summary

Problems solved by technology

[0003] At present, the commonly used sleds are mainly standard Antarctic sleds. The existing standard sleds have problems such as single type, heavy weight, difficult maintenance, easy wear, high maintenance cost and short service life.

Moreover, the standard sled cannot meet the transportation of large materials. Usually, the standard sled can only carry a 20-foot container, which has more restrictions on the size of the transported materials.

At the same time, the external dimensions of the Antarctic mobile crew cabin are limited, making the living space of the on-site staff relatively crowded, which hinders the further development of the Antarctic inland investigation to a certain extent.

With the increase of Antarctic inland expedition missions, the maintenance frequency of standard sleds is getting higher and higher, seriously affecting the normal progress of expedition missions
