The side supports are arranged on both sides and are connected through two crossbeams on the upper part to form an entire frame structure. The hydraulic rotary device consists of a low-speed big-torque hydraulic motor, a brake, a planetary reducer and pinions, six hydraulic rotary devices are respectively arranged on the side supports on both sides, the pinions of three hydraulic rotary devices on the side support on each side are arranged in equiangular triangle position and are meshed with the tail-end big gears positioned on both sides of the double roller to form a open type gear transmission system; the hydraulic motor converses the hydraulic power into the mechanical rotary power and transfers the torque onto the tail-end big gears through the pinions. The utility model adopts the multi-point driving system, can ensure that each driving point has equal force to the roller, embodies the best characteristic of the hydraulic drive, and has a simple and rational integral structure, small volume and light weight.
Description
Technical field
The utility model relates to winch, the winch that particularly a kind of large-scale multi-dot hydraulic pressure drives.
Background technology
Existing large-scale winch generally adopts the single-point reducing motor to drive, and its weak point has following all points:
1. the winch single-point is stressed, causes stress point skewness, unreasonable, makes that the integral structure strained condition is not good enough.
2. when adopting reducing motor to drive, can't accomplish accurate multiple spot power driven in synchronism.
3. the winch single-point drives, make terminal big gear wheel must the intensity height, volume is big, its manufacturability is poor on making, the productive costs height.
4. after adopting single-point to drive, if drive point breaks down, whole winch can't be worked, and this has just reduced the safe reliability of equipment.
5. after adopting single-point to drive, cause machine volume huge, weight is very heavy, and globality and installation property are relatively poor.
Summary of the invention
Task of the present utility model provides a kind of improved large multipoint hydraulically driven winch, and it has solved that existing large-scale winch adopts the single-point reducing motor to drive to make the stress point skewness and problem such as poor, the productive costs height of manufacturability on making.
The technical solution of the utility model is as follows:
A kind of large multipoint hydraulically driven winch, it comprises base, the limit support, crossbeam, double crosslinking drum, terminal big gear wheel and steel rope, it also comprises hydraulic permeability reversing gear;
Described limit support is placed in two sides, and the dual side-edge support connects by two crossbeams in top again, forms a general frame structure;
Described hydraulic permeability reversing gear is made up of low speed high torque hydraulic motor, drg, planetary reducer and miniature gears, six hydraulic permeability reversing gears are placed in respectively on the dual side-edge support, the miniature gears of three hydraulic permeability reversing gears is pressed the equilateral triangle location arrangements on every side support, and be meshed with the terminal big gear wheel that is positioned at double crosslinking drum two sides, form an exposed gear driving system, HM Hydraulic Motor converts hydraulic power to mechanical rotation power, transfers torque on the terminal big gear wheel through miniature gears;
Two fag ends of described steel rope are fixed on two ends of double crosslinking drum by pressing plate, and the positive and negative rotation by double crosslinking drum makes two end steel ropes regain simultaneously and emit.
Large multipoint hydraulically driven winch of the present utility model adopts the Multipoint Drive system, and this Multipoint Drive system is made up of many covers HM Hydraulic Motor, drg and planetary reducer.Winch of the present utility model has following advantage:
1. adopt the hydraulic pressure Multipoint Drive, can guarantee that each drive point equates the power of reel, has embodied hydraulically powered optkmal characteristics.
2. after the employing Multipoint Drive, the stress value of each drive point of reel is reduced by dispersion, and stressedly be evenly distributed, symmetry, this structural stress state for winch is highly profitable.
3. after the employing Multipoint Drive, the complete machine safety factor and the reliability of winch greatly increase, and have obviously improved safety redundancy.If certain drive point breaks down, all the other drive points still can drive winch work.
4. after the employing Multipoint Drive, hydraulic permeability reversing gear is divided into a plurality of dispersion junior units, can be integrated with winch, make integral structure simple, reasonable, and volume is little, in light weight.
5. wait for the important spare part of winch, terminal big gear wheel and hydraulic permeability reversing gear, owing to be divided into several sections, therefore reduced volume and weight, made normalisation, universalization and the anufacturability of parts all be significantly improved, its economy also is greatly improved.
