Abstract

The utility model discloses the dragline tool that a kind of skifield is used, a kind of flexible rope formula is dragged and is led device, it is made up of pipe expansion joint (2) and "T"-shaped bar (3), pipe expansion joint (2) comprises housing (2-1), winding wheel (2-2), coiled springs (2-3), spring case (2-4), axle (2-5), pulling rope (2-6) and crotch (2-14), crotch is fixed on the outer wall of housing upper end, winding wheel, coiled springs, spring case and axle are arranged in the housing, winding wheel and spring case are fixed and can be pivoted, thereby coiled springs is arranged in the spring case and is connected with spring case with axle respectively and can makes the two generation elastic recoil, one end of pulling rope is wound on the winding wheel, and the other end passes housing and is connected with "T"-shaped bar upper end.Because "T"-shaped bar telescopic variation is twined on winding wheel by pulling rope or loosened and finish, so the variation of its distance can be very big, so the adaptive capacity that snow pack ground is just changed is very strong.

Description

Flexible rope formula is dragged and is led device

Technical field

The utility model relates to a kind of people carrier that is used for the skifield passengers surface lift.

Background technology

Telescopic the dragging of skifield use at present led device, as shown in Figure 1, because that its retractor device 1 inner employing is compression spring 1-1, therefore its flexible ability is very limited, this just requires ground very smoothly could successfully transport to the trail epimere to the slider from the trail hypomere, and this increases the construction cost of skifield greatly, in addition, each is telescopic drags and leads device and once can only transport a slider, and conveying efficiency is lower.

The utility model content

Lead device and adapt to ground ability, defective that conveying efficiency is low in order to overcome dragging of prior art, provide a kind of ground ability that adapts to strong and conveying efficiency is high drags and lead device.

The utility model is realized by following proposal: a kind of flexible rope formula is dragged and is led device, it is made up of pipe expansion joint 2 and "T"-shaped bar 3, pipe expansion joint 2 comprises housing 2-1, winding wheel 2-2, coiled springs 2-3, spring case 2-4, axle 2-5, pulling rope 2-6 and crotch 2-14, crotch 2-14 is fixed on the outer wall of housing 2-1 upper end, winding wheel 2-2, coiled springs 2-3, spring case 2-4 and axle 2-5 are arranged in the housing 2-1, winding wheel 2-2 and spring case 2-4 fix and can rotate around axle 2-5, axle 2-5 is captiveed joint with housing 2-1, thereby coiled springs 2-3 is arranged in the spring case 2-4 and is connected with spring case 2-4 with axle 2-5 respectively and can makes the two generation elastic recoil, the end of pulling rope 2-6 is wound on the winding wheel 2-2, and the other end passes housing 2-1 and is connected with the upper end of "T"-shaped bar 3.

The utility model in use, pipe expansion joint 2 is connected on the cableway of motion by the crotch 2-14 of its upper end, the pulling rope 2-6 of pipe expansion joint 2 connects the "T"-shaped bar 3 of its lower end, the slider is sitting on the "T"-shaped bar 3 just by the epimere transportation to snow pack.Because "T"-shaped bar 3 is twined on winding wheel 2-2 by pulling rope 2-6 with respect to the telescopic variation of pipe expansion joint 2 distances or loosens and finish, therefore the variation of its distance can be very big, so the adaptive capacity that snow pack ground is just changed is very strong, and the slider when taking as snug as a bug in a rug.Therefore the cross bar 3-1 that "T"-shaped bar 3 stretches out to both sides can both sit the people, and one is dragged and leads device and once can transport two people, and efficient doubles.The utlity model has reasonable in design, reliable operation and have the advantage of big promotional value.

Description of drawings

Fig. 1 is the existing telescopic structural representation that leads device that drags, Fig. 2 is a structural representation of the present utility model, Fig. 3 is the structural representation of pipe expansion joint 2 in the specific embodiment one, Fig. 4 is that the B of Fig. 3 is to view, Fig. 5 is the C-C cutaway view of Fig. 3, Fig. 6 is the structural representation of "T"-shaped bar 3, and Fig. 7 is that the A of Fig. 6 is to view.

The specific embodiment

The specific embodiment one: specify present embodiment below in conjunction with Fig. 2 to Fig. 5.It is made up of pipe expansion joint 2 and "T"-shaped bar 3, pipe expansion joint 2 comprises housing 2-1, winding wheel 2-2, coiled springs 2-3, spring case 2-4, axle 2-5, pulling rope 2-6 and crotch 2-14, crotch 2-14 is fixed on the outer wall of housing 2-1 upper end, winding wheel 2-2, coiled springs 2-3, spring case 2-4 and axle 2-5 are arranged in the housing 2-1, winding wheel 2-2 and spring case 2-4 fix and can rotate around axle 2-5, axle 2-5 is captiveed joint with housing 2-1, thereby coiled springs 2-3 is arranged in the spring case 2-4 and is connected with spring case 2-4 with axle 2-5 respectively and can makes the two generation elastic recoil, the end of pulling rope 2-6 is wound on the winding wheel 2-2, and the other end passes housing 2-1 and is connected with the upper end of "T"-shaped bar 3.In addition, also be provided with the speed damping arrangement in the housing 2-1, the speed that pulling rope 2-6 is returned twine on the winding wheel 2-2 can not be too fast.The brake facing 2-7 on the ancient piece of jade, round, flat and with a hole in its centre, shoe piece 2-8 and rhombus sheet 2-9 form the speed damping arrangement in the housing 2-1 by being fixed on, the end of shoe piece 2-8 is hinged on the jointed shaft 2-11, jointed shaft 2-11 is fixed on the spring case 2-4, the other end of shoe piece 2-8 is hinged on the rhombus sheet 2-9 by bearing pin 2-13, and rhombus sheet 2-9 is through on the 2-5.As shown in Figure 5; when under the return effect of winding wheel 2-2 at coiled springs 2-3 fast during left-hand revolution; shoe piece 2-8 brake facing 2-7 on housing 2-1 inwall under action of centrifugal force reclines, thereby is slowed down rotating speed, has played the effect of protecting each part.

The specific embodiment two: specify present embodiment below in conjunction with Fig. 4, Fig. 6 and Fig. 7.The difference of present embodiment and embodiment one is: pass housing 2-1 place at pulling rope 2-6, also be provided with guard ring 2-12, oval-shaped guard ring 2-12 is captiveed joint with housing 2-1, flat duckbill is processed in the upper end of "T"-shaped bar 3, and the lower end of "T"-shaped bar 3 is provided with the cross bar 3-1 perpendicular to "T"-shaped bar 3 bodies of rod.So be provided with, drag when leading device and not having the slider to take when of the present utility model, connect in the pulling rope indentation pipe expansion joint between "T"-shaped bar and the pipe expansion joint, the flat duckbill upper end of "T"-shaped bar 3 is injected among the guard ring 2-12, play the effect of location, two cross bars that make "T"-shaped bar 3 are all the time perpendicular to the cableway of motion, and convenient slider afterwards takes.
