Description

[0002] The polar environment (such as the South Pole and the North Pole) is characterized by extreme wind, extremely low temperature, ice and snow coverage, and complex terrain, and is a key area for human scientific investigation, resource exploration and rescue missions. The transportation carrier is the core infrastructure for ensuring the transportation of materials and the transfer of personnel in scientific investigation activities, and its performance directly affects the efficiency, cost and safety of the mission. At present, in China's Antarctic scientific investigation, the main way to go from the coast to the inland is to pull a train of sleds by a tractor. The sleds are loaded with living quarters, functional cabins and other materials. However, due to the complex road conditions, the sleds vibrate greatly during the journey, which causes the scientific investigation team members to have to stay in the tractor and only return to the cabin when camping; at the same time, there is a risk of damage to the materials, which seriously affects the smooth progress of the scientific investigation mission. In addition, the sleds have no power and rely solely on the tractor to adjust their position, which is time-consuming and laborious, and the sleds cannot be tightly connected to form a large platform, and personnel need to frequently get on and off the sleds when moving between different cabins, which is extremely inconvenient.

Each fixed seat 174 has a first through hole 177 through which the traction beam 171 passes. The two first limiting members 172 are located on opposite sides of the two first through holes 177 to prevent the traction beam 171 from disengaging from the first through holes 177. The traction beam 171 extends along a second horizontal direction F2. Two fifth connecting parts 176 are provided on the traction beam 171. The fifth connecting parts 176 are rotatably connected to the traction beam 171 via a traction plate. The fifth connecting parts 176 can be shackles, universal joints, or ball joints.

[0049] Specifically, the traction frame 13 includes a frame body 131, which includes a first member, a second member, a third member, and a fourth member. The two ends of the first member are connected to one end of the second member and one end of the third member, respectively. The other ends of the second and third members are connected to the fourth member. One end of the fourth member is connected to the side wall of the first member, and the other end of the fourth member is provided with a second connecting part 133. The first, second, and third members form a triangle, and two first connecting parts 132 are provided on the side of the first member away from the fourth member.

[0050] Specifically, the first connecting part 132 is a clamp, and the traction beam 171 is a cylinder. The first connecting part 132 is snapped into and rotatably connected to the traction beam 171. The traction frame 13 can rotate relative to the traction beam 171 and is detachable. The second connecting part 133 is a shackle, universal joint, or ball joint.

[0051] In this embodiment, the cargo platform 11 includes multiple traction mechanisms 112 and multiple third connecting parts 111. The traction mechanisms 112 and the third connecting parts 111 are located on opposite sides of the cargo platform 11. The traction mechanism 112 includes a power unit 1121 and a fourth connecting part 1122 connected to the output end of the power unit 1121. The fourth connecting part 1122 is used to connect with the third connecting parts 111 of other polar transport vehicles 10. The power unit 1121 is used to drive the third connecting parts 111 to extend or shorten, thereby adjusting the distance between the two polar transport vehicles 10.

[0052] The third connecting part 111 can be a connecting post with a protrusion, and the fourth connecting part 1122 can be a hook that hooks onto the connecting post to form a connection. When the convoy is encamped, each polar transport vehicle 10 can be adjusted in position through the traction mechanism 112 and the connecting post with a protrusion, and can be pulled closer and spliced ​​together to form a large platform.

[0053] Specifically, the cargo platform 11 includes a first long side and a second long side, and a first short side and a second short side, which together form a rectangular frame. Three traction mechanisms 112 are spaced apart on the first long side, three third connecting parts 111 are spaced apart on the second long side, two traction mechanisms 112 are spaced apart on the first short side, and two third connecting parts 111 are spaced apart on the second short side.

[0054] The first through hole 177 can be an elongated hole, allowing the traction beam 171 to move up and down, rotate, and move horizontally a certain distance along the axial direction of the hole. When the vehicle travels on a bumpy road surface, each skid plate can move up and down independently, preventing the upper cargo platform from tilting. The use of springs and hydraulic rods reduces vehicle vibration. A traction plate with shackles is installed at each end of the traction beam. During convoy movement, the two ends of the traction chain are attached to the shackles of the front and rear vehicles, connecting the traction beams of the front and rear vehicles.

[0055] The towing frame 13 and the traveling assembly 12 are detachably connected. The main body of the towing frame 13 is a tripod structure welded from profiles. Each end of the towing frame 13 is equipped with a clamp, which is locked onto the cylindrical traction beam 171 in the middle of the two traveling assemblies 12. The towing frame 13 can rotate around the cylindrical traction beam 171. When it is necessary to remove the towing frame, the fasteners on the clamps can be loosened to remove the towing frame.

[0056] The tow frame has a connecting plate at its front end, with shackles (or universal joints, ball joints, or other connecting structures) on the connecting plate. The tow frames on two adjacent vehicle platforms are connected by shackles, so that when the front vehicle platform moves, it can drive the rear vehicle platform to move. When the convoy turns uphill or downhill, the rear tow frame can rotate horizontally or vertically around the shackles of the front tow frame, improving the convoy's adaptability to various complex terrains.

[0057] Furthermore, this application provides a polar transportation system, which includes at least two interconnected polar transportation vehicles 10, wherein the polar transportation vehicle 10 is any of the polar transportation vehicles described above.

[0058] like Figure 5 As shown in the embodiment of this application, the polar transportation system includes a tractor 20, which is connected to a second connecting part 133 on one of the polar transportation vehicles 10. The tractor 20 is connected to the cargo platform 11 of one of the polar transportation vehicles 10 via two first traction chains 31. Specifically, the tractor 20 is connected to two fifth connecting parts 176 on one of the polar transportation vehicles 10 via two first traction chains 31.

[0059] In this embodiment of the application, the polar transportation system includes two polar transportation vehicles 10, with a tractor and the two polar transportation vehicles 10 arranged in sequence, and the second connecting parts 133 on the two adjacent polar transportation vehicles 10 are connected.

[0060] Furthermore, the tractor 20 is connected to the second connection portion 133 on one of the polar transport vehicles 10 via a third traction chain 33, and two first traction chains 31 are symmetrically arranged on both sides of the third traction chain 33. Specifically, two adjacent polar transport vehicles 10 are connected by two second traction chains 32, which are located on both sides of the second connection portion 133 on the polar transport vehicle 10, thereby improving stability during movement.

[0061] Figure 5 In the middle, the polar transport system is in convoy mode. The tractor connects to the front tow frame shackle of the first polar transport vehicle 10, the rear tow frame of the front vehicle connects to the front tow frame of the rear vehicle, and the rear tow beam of the front vehicle and the front tow beam of the rear vehicle are connected by a tow chain. The rear tow frame of the last polar transport vehicle 10 is removed.

[0062] See Figure 6 In another specific embodiment, the polar transport system includes two polar transport vehicles 10, wherein the third connection 111 of one polar transport vehicle 10 and the fourth connection 1122 of the other polar transport vehicle 10 are connected by a fourth traction chain 34.

[0063] Figure 6In the process, the polar transport system is in a horizontal splicing mode, where multiple polar transport vehicles 10 are parked approximately side by side, and a lateral traction mechanism is used to pull each polar transport vehicle 10 closer together.

[0064] See Figure 7 In another specific embodiment, the polar transport system includes two polar transport vehicles 10, with a tractor and the two polar transport vehicles 10 arranged sequentially. The fifth connection portion 176 of one polar transport vehicle 10 and the fifth connection portion 176 of the other polar transport vehicle 10 are connected by a fifth traction chain 35.

[0065] Figure 7 In the process, the polar transport system is in a longitudinal splicing mode. After the tractor stops, the towing frame and towing chain of the polar transport vehicle 10 are removed, and the longitudinal traction mechanism is used to pull the polar transport vehicles 10 closer together.

[0066] See Figure 8 The polar transport system is in a horizontal and vertical splicing mode. In another specific embodiment, the polar transport system includes three polar transport vehicles 10, wherein the long sides of the first polar transport vehicle 10 and the second polar transport vehicle 10 are parallel, and the long side of the third polar transport vehicle 10 is parallel to the short side of the first polar transport vehicle 10. The cargo platform 11 of the polar transport vehicle 10 has three third connecting parts 111 on its long side and two fourth connecting parts 1122 on its short side. The two third connecting parts 111 on the long side of the third polar transport vehicle 10 are each connected to one fourth connecting part 1122 on the long side of the first polar transport vehicle 10 and the second polar transport vehicle 10. The third third connecting part 111 on the long side of the third polar transport vehicle 10 is connected to one fourth connecting part 1122 on the long side of the first polar transport vehicle 10 and one fourth connecting part 1122 on the long side of the second polar transport vehicle 10.

[0067] The front and rear tow racks are designed to connect vehicles longitudinally into a convoy. The tow racks can rotate horizontally and vertically, allowing the convoy to better adapt to uneven road conditions. The tow chain serves as a backup to the tow racks; if a tow rack fails, the tow chain intervenes to tow the following vehicle. It also limits the turning radius, preventing collisions between vehicles when the turning radius is too small. When the convoy is camping for an extended period and requires a larger platform, the vehicle positions can be adjusted using a towing mechanism, allowing the vehicles to be pulled together and joined to form a larger, integrated platform, facilitating personnel movement.

[0068] Compared to related technologies, the polar transport vehicle includes a cargo platform and a traveling device, which are vertically spaced apart. The traveling device is located at the bottom of the cargo platform, and a first reset device connects the traveling device and the cargo platform. The first reset device restricts the movement of the cargo platform relative to the traveling device when the traveling device moves closer to or further away from the cargo platform. This application can improve the vibration reduction effect of the polar transport vehicle.

Specific examples have been used to illustrate the principles and implementation methods of this application. The description of the above embodiments is only for the purpose of helping to understand the method and core ideas of this application. At the same time, for those skilled in the art, there will be changes in the specific implementation methods and application scope based on the ideas of this application. Therefore, the content of this specification should not be construed as a limitation of this application.
