Abstract

The utility model provides a sled comprising two sled legs and an operating rack. The sled legs are symmetrically disposed at the lower end of the operating rack. Each sled leg is provided with a traction hole, a U-shaped groove and a support lug. A triangular support and a traction beam are further connected to the sled legs. Two ends of the traction beam have cylindrical surfaces and are placed in the U-shaped grooves of the left and right sled legs; the lower portion of the traction beam is positioned through pins. The sled is applicable to severe work environments, resistant to impact, long in service life, easy to manufacture, and low in cost. The sled can be used as a small-sized snowfield motorcycle-driven sled to allow short-range transportation of few materials in polar research.

Description

A kind of sled

Technical field

The utility model relates to small-sized snowfield transportation means, specifically, relates to a kind of sled.

Background technology

But along with the development of China's polar expedition cause, since 1985, China builds up Analyses At The China Antarctic Great Wall Station, station, middle mountain, station, the Kunlun in succession, Chinese Arctic Yellow River Station, in polar expedition station, the short range transportation demand of a small amount of goods and materials occurs;

But the transportation sled using is at present large-scale transportation sled or sled of a primitive type substantially.

Our imagination, can design a kind of like this sled, this sled: can adapt to severe working environment, shock-resistant, long service life, easily manufacture and with low cost; And can be used as the towed sled of small-sized ski type motorbike, to meet the short range transportation of a small amount of goods and materials in polar expedition.

Utility model content

The utility model provides a kind of sled to achieve these goals.

Sled of the present utility model, comprises 2 sled pin, Working gantry; 2 described sled pin are symmetricly set on described work pallet lower end, be provided with towing pad, U-shaped groove, support otic placode on described sled pin; On described sled pin, also connect A-frame and draw beam; The two ends of described draw beam are the face of cylinder and are placed in the U-lag on left and right sled pin, and locate with bearing pin bottom.

Further, described A-frame 2 two ends are provided with bearing pin, and are hinged with the towing pad of described sled pin respectively.

Further, the anterior supporting base of described Working gantry respectively with described sled pin on supporting otic placode be hinged, described work pallet is also provided with rear support beam and is installed on draw beam by spacing bearing pin.

Further, on described A-frame, be set with front haulage frame, and be connected with draw beam by tow chain, connecting panel; Such setting, can make the tractive force on front haulage frame be delivered to draw beam, and then passes to left and right sled pin by U-lag, and A-frame 2 guarantees the conformability of travel direction and tractive force direction by front haulage frame.

The two ends of described draw beam are the face of cylinder and are placed in the U-lag on left and right sled pin, and locate with bearing pin bottom; Such setting can prevent from deviating from U-lag in draw beam operational process;

Sled of the present utility model, can adapt to severe working environment, shock-resistant, long service life, easily manufacture and with low cost; And can be used as the towed sled of small-sized ski type motorbike, to meet the short range transportation of a small amount of goods and materials in polar expedition.

The specific embodiment

Below with reference to accompanying drawing, embodiment of the present utility model is described.The element of describing in an accompanying drawing of the present utility model or a kind of embodiment and feature can combine with element and feature shown in one or more other accompanying drawings or embodiment.It should be noted that for purposes of clarity, in accompanying drawing and explanation, omitted and the utility model expression and description irrelevant, parts known to persons of ordinary skill in the art or processing.

Below in conjunction with accompanying drawing, the utility model is described further.

Sled of the present utility model, is comprised of front haulage frame 1, A-frame 2, towing plate 3,4,2 sled pin 5 of Working gantry, draw beam 6, tow chain 7, connection bearing pin 8, tow chain 9, spacing bearing pin 11 etc. as Figure 1-Figure 4.

2 described sled pin are symmetricly set on described work pallet 4 lower ends, be provided with towing plate 12, U-shaped groove 14, support otic placode 13 on described sled pin 5;

Described sled pin 5 is connected with described A-frame 2, draw beam 1; The two ends of described draw beam are the face of cylinder and are placed to respectively in the U-lag 14 on described sled pin 5, and locate with bearing pin bottom.

Described sled pin 5 is combined into metastable coasting mechanism with A-frame 2 with draw beam 6: A-frame 2 is connected with the towing plate 12 of described sled pin 5 respectively by being connected bearing pin 8 two ends; Draw beam 6 two ends are the face of cylinder and are respectively installed in the U-lag 14 on described sled pin 5, and locate with bearing pin bottom, prevents from deviating from U-lag in draw beam operational process.

Described Working gantry 4 front portions are provided with supporting otic placode and are hinged with the supporting base on described sled pin, and rear support beam is installed on draw beam by spacing bearing pin 11.

Described front haulage frame 1 is sleeved on A-frame 2, and be connected with draw beam 6 by tow chain 7, towing plate 3, make the tractive force on front haulage frame 1 be delivered to draw beam 6, and then pass to left and right sled pin by the U-lag on sled pin, make sled pin obtain the power sliding at snowfield, A-frame 2, by the guiding of front haulage frame 1, guarantees the conformability of travel direction and tractive force direction simultaneously.

Although described the utility model and advantage thereof in detail, be to be understood that in the situation that do not exceed the spirit and scope of the present utility model that limited by appended claim and can carry out various changes, alternative and conversion.And the application's scope is not limited only to the specific embodiment of the described process of specification sheets, equipment, means, method and step.One of ordinary skilled in the art will readily appreciate that from disclosure of the present utility model, according to the utility model, can use and carries out with the essentially identical function of corresponding embodiment described herein or obtain process, equipment, means, method or step result essentially identical with it, that existing and will be developed future.Therefore, appended claim is intended to comprise such process, equipment, means, method or step in their scope.
