Embodiment 1

[0017] Embodiment 1, polar lifting equipment suitable for Antarctic inland areas, refer to figure 1 , figure 2 Summary of the invention: the present invention is specially designed for the specific conditions of the Antarctic inland area. The name of each component in the figure: container base 1; tower crane column 2; tower crane cross arm 3; lifting hook 4; anti-tilt steel cable 5;

[0018] Its characteristics are as follows:

[0019] 1. Use the 20-foot half-container that is transported to the Antarctic on the ship, and the chassis that is left in the Antarctic after the cargo is transported and rebuilt into the base of the lifting tower, instead of the base that the general lifting tower needs to be poured with reinforced concrete on site, to avoid the Antarctic Cement cannot be poured at low temperatures.

[0020] 2. Use the existing ice core drill in Antarctica to drill a hole on the Antarctic inland ice sheet and put in a special steel pipe to fix the container chas...

Abstract

The invention discloses a polar region derrick tower suitable for Antarctic inland areas. The polar region derrick tower is characterized in that a chassis of a container is adopted on the base of an existing derrick tower; multiple steel pipes are fixedly arranged below the chassis of the container; the multiple steel pipes are fixed in drill holes of Antarctic inland ice covers; and the chassis of the container and the multiple steel pipes are filled with frozen water. According to the optimization scheme, windproof and anti-tipping wire ropes are arranged, and the fixing mode of the windproof and anti-tipping wire ropes and the ground comprises the following steps: drilling in proper parts of the ice covers by using an ice core drill, wherein the depth is over 5m; putting the steel pipes with the diameters of 50mm*5m and threaded suspension clasps, watering, fixing the steel ropes, and strengthening the windproof and anti-tipping capacity of the derrick tower. According to the polar region derrick tower disclosed by the invention, the defects of conventional equipment and capacity are overcome, the limit weight limitation and the height limitation of the lifting tower are greatly increased, and the derrick tower is applied to operating under severe conditions of the Antarctic inland areas and is used for mounting large precision equipment devices. According to the derrick tower disclosed by the invention, local materials are taken as partial parts in the tower, and the equipment cost and the transportation cost are saved.

Description

technical field [0001] The invention relates to a lifting device, in particular to a polar lifting device suitable for the Antarctic inland area. Used to install larger precision equipment. technical background [0002] The inland of Antarctica is an ice-covered land, and the transportation and lifting conditions are harsh, which makes it difficult to install large-scale instruments and equipment. For example, in the existing Kunlun Station, the equipment is first transported to the near shore by snow dragon boat, then lifted by helicopter to the snowmobile to Kunlun Station, and then hoisted to the installation site by installing lifting equipment on the snowmobile or by helicopter. Finally, it is lifted and installed by a snowmobile. [0003] Due to the limit weight and height limit of helicopter lifting and snowmobile lifting working in Antarctica, the general lifting weight is less than 5 tons and the height is less than 10 meters. For the larger precision e...
