Embodiment Construction
[0014] Such as figure 1 , 2 , 3, and 4, the rotating shaft of the runner 1 is sleeved with a gear sleeve 9, and the two ends of the gear sleeve 9 are respectively provided with a spur gear 7 and a worm gear 10, and the gear sleeve 9 is connected with the shift fork 11, and the The fork 11 is moved to make the gear sleeve 9 mesh with the spur gear 7 or the worm gear 10, and the runner 1 is in the fast-rotating working condition when the gear sleeve 9 and the spur gear 7 are meshed. At this time, the transmission sequence is 4-5-6-7-9 -1 can realize fast rotation; the runner 1 is a low-speed self-locking working condition in the meshing state of the gear sleeve 9 and the worm wheel 10, and at this time, the transmission sequence 4-10-8-9-1 realizes the low-speed self-locking; the worm wheel 10 is formed by The hydraulic motor 4 is directly driven to rotate, and the spur gear 7 is connected to the hydraulic motor 4 through a reduction gear mechanism, and is driven to rotate by t...

Provided is a large-change-speed-ratio forestry cable car. A rotary shaft of a rotating wheel is in sleeved connection with a gear sleeve, a straight gear and a worm wheel are arranged at two ends ofthe gear sleeve respectively, the gear sleeve is connected with a shifting fork, the shifting fork makes the gear sleeve meshed with the straight gear and the worm wheel, the rotating wheel is under aquick rotating work condition in a gear sleeve and straight gear meshing state, and the rotating wheel is under a low-speed self-locking work condition in a gear sleeve and worm wheel meshing state.The worm wheel is directly driven to rotate by a hydraulic motor, and the straight gear is connected with the hydraulic motor through a speed-reducing gear mechanism and is driven to rotate by the hydraulic motor. The large-change-speed-ratio forestry cable car has the advantages that the large-change-speed-ratio forestry cable car has the three functions of a taking-up cable or a tensioning cableand a pull hoist, the cable car uses the quick taking-up cable under the work condition of the taking-up cable, the pull hoist adopts medium speed, a low-speed large pull force is needed and self locking is also needed under the work condition of the tensioning cable, the difference of two transmission ratios is large, self locking can be achieved by utilizing the large transmission ratio, and two characteristics are combined to form a whole.
Description
technical field [0001] The invention relates to the technical field of cable cars, in particular to a forestry cable car with a large variable speed ratio. Background technique [0002] Chinese patent 200810024660.8 discloses a two-speed winder. It contains frame, power shaft, power mechanism and winding shaft. The power shaft is connected with the power mechanism. The power shaft is parallel to the winding shaft. It is characterized in that the winding shaft includes a high-speed winding shaft and a low-speed winding shaft, and the two winding shafts are respectively located on both sides of the power shaft. There is a gear sleeve on the power shaft, and the gear sleeve is in a sliding fit and a fixed fit with the axial direction and the circumferential direction of the power shaft respectively. A slide bar and an oil cylinder connected with the slide bar and capable of longitudinally moving the slide bar are arranged above the power shaft. There is a shift fork in the...
