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

Be applicable to the polar region derrick tower in Antarctic Inland area

Technical field

The present invention relates to a kind of lifting appliance, be specifically related to a kind of polar region lifting appliance being applicable to Antarctic Inland area.For installing relatively large precision equipment device.

Technical background

Antarctic Inland is the land of an ice sheet, transport and lifting inclement condition, causes large-scale instrument and equipment to install difficulty.As station, existing the Kunlun, equipment conveying first transports to offshore place with snow dragon-boat, then hang on snow wagon with helicopter and transport to station, the Kunlun, then with snow wagon filling lifting appliance or helicopter hangs place of erection, finally install by snow wagon lifting.

Because the helicopter lifting that works in the South Pole and snow wagon lift by crane limit weight and limitation in height, general hoisting weight is below 5 tons, height is below 10 meters, for the relatively large precision equipment that will develop, such as, next 2.5 meters of optical infrared glass at China station, the Kunlun, its pts wt and highly all exceed this weight limits and limitation in height, causes difficulty.

And larger derrick tower, its transport, ground matrix manufacturing, polar region is installed and is all had any problem, and cost is very high.

Summary of the invention

The object of this invention is to provide a kind of polar region lifting appliance being applicable to Antarctic Inland area.The present invention can overcome the limit weight restriction and limitation in height of lifting by crane in prior art, and lifting appliance transport makes in Antarctic Inland area, and polar region is installed and all had any problem, and a cost very high-technology difficult problem; The section components that the present invention uses is gathered materials on the spot, and saves equipment cost and traffic cost.The limit weight restriction of the present invention's lifting and limitation in height increase substantially, and work, especially for installing relatively large precision equipment device under being applicable to Antarctic Inland area mal-condition.

The technical scheme completing foregoing invention task is, a kind of polar region lifting appliance being applicable to Antarctic Inland area, it is characterized in that, the base of this derrick tower adopts the chassis of freight container, be fixed with some steel pipes below this container bottom, some described steel pipes are fixed in the boring of Antarctic inland ice_sheet traverse; Meanwhile, in this container bottom and in some described steel pipes, all freeze water is filled.

Described " filling freeze water " refers to: according to coefficient of expansion during water freezing, the precalculated water yield, reserved expansion space in this container bottom and in some described steel pipes, to make after water freezing basic overflow again.

Further improvement of the present invention, has following prioritization scheme:

1, described " adopting the chassis of freight container ", recommends the chassis of employing 20 forty equivalent unit 40 (half chests);

2, between the described 20 forty equivalent unit 40 chassis as base and derrick tower, be fixedly connected by installing steel plate, screw and bolt;

3, be applicable in the polar region lifting appliance in Antarctic Inland area described in, all movable parties are all lubricated with low temperature grease;

4, be applicable to the material of the polar region lifting appliance in Antarctic Inland area described in, the steel being applicable to low temperature are made, and such as, adopt 16MnR steel or stainless steel;

5, be applicable to the surrounding of the polar region lifting appliance in Antarctic Inland area described in, be provided with windproof and overturning-preventing cable wire, this windproof and overturning-preventing cable wire and ground fixed form is: be drilled in ice sheet suitably drill with ferrule hole with ice stamen, the degree of depth is more than 5 meters; Putting into diameter is that 50 ㎜ *, 5 meters of steel pipes and screw thread are withheld, and waters water, in order to fixing tightwire, strengthens the windproof and overturning-preventing ability of tower crane.

Instant invention overcomes the limit weight restriction of prior art lifting and the deficiency of limitation in height, the ground also overcoming lifting appliance makes in Antarctic Inland area, installs and all have any problem, and a cost very high-technology difficult problem; The limit weight restriction of the present invention's lifting and limitation in height increase substantially, and work, for installing relatively large precision equipment device under being applicable to Antarctic Inland area mal-condition.The section components that the present invention uses is gathered materials on the spot, and saves equipment cost and traffic cost.

Accompanying drawing explanation

Fig. 1 is container base structural representation of the present invention;

Fig. 2 is tower crane structural representation of the present invention.

Detailed description of the invention

Embodiment 1, is applicable to the polar region lifting appliance in Antarctic Inland area, with reference to Fig. 1, Fig. 2: the present invention designs for the particular case in Antarctic Inland area specially.All parts title in figure: container base 1; Tower crane column 2; Tower crane transverse arm 3; Load hook 4; Anti-dumping cable wire 5; Set collar 6; Ice sheet 7.

Its feature is as follows:

1. to utilize on ship cargo transport to 20 feet of half chests in the South Pole, stay the chassis in the South Pole after cargo transport, change system into derrick tower base, and need not the general base that pours into of derrick tower need scene reinforced concrete, cannot cement be watered under avoiding South Pole low temperature.

2. be drilled on Antarctic inland ice_sheet traverse with the South Pole existing ice stamen and put into special steel pipe after boring, fix this container bottom.
