Abstract
The large multipoint hydraulically driven winch includes a pedestal, side racks, crossbeams, a dual reel, an end large gear, a steel cable and hydraulic reversing gears. Two side racks are connected with two crossbeams to form one integral frame structure; six hydraulic reversing gears comprising hydraulic motor, brake, planetary speed reducer and small gear each are mounted separately onto two side racks; the small gears in three hydraulic reversing gears on the same side rack are arranged in the form of an equilateral triangle and meshed with the large gear to form one opened gear transmission system; and the hydraulic motors convert the hydraulic power into mechanical rotating power transmitted through the small gears to the large gear. The multipoint driving system has equal driving forces to the reel in different points, optimal hydraulic driving characteristic and other advantages.
Description
Technical field
The present invention 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 invention 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.
Technical solution of the present invention 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 invention 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 invention 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.
Description of drawings

Fig. 2 is the left TV structure scheme drawing by winch shown in Figure 1.
Fig. 3 is the plan structure scheme drawing by winch shown in Figure 1.
The specific embodiment
Referring to Fig. 1 to Fig. 3, the present invention is a kind of large multipoint hydraulically driven winch, especially is large-scale 6 hydraulically driven winch, and it is equipped with base 1, limit support 2, crossbeam 3, double crosslinking drum 4, terminal big gear wheel 5, steel rope and hydraulic permeability reversing gear 7.Limit support 2 is placed in two sides, and dual side-edge support 2 connects by two crossbeams in top 3 again, forms a general frame structure.
Hydraulic permeability reversing gear 7 is made up of low speed high torque hydraulic motor, drg, planetary reducer and miniature gears.Six hydraulic permeability reversing gears 7 are placed in respectively on the dual side-edge support 2, and three hydraulic permeability reversing gears 7 are set on every side support 2.The miniature gears of hydraulic permeability reversing gear 7 is pressed the equilateral triangle location arrangements, and is meshed with the terminal big gear wheel 5 that is positioned at double crosslinking drum 4 two sides, forms 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.Drg on the hydraulic permeability reversing gear is used between the operation of winch and the braking after stopping.
Two fag ends of steel rope are fixed on two ends of double crosslinking drum 4 by pressing plate, and the positive and negative rotation by double crosslinking drum makes two end steel ropes regain simultaneously and emit.
Brake safe when winch is stopped has been installed click stopper 6 on winch.Ratchet is equipped with at middle part at double crosslinking drum 4, on base 1 ratchet is housed, and ratchet and ratchet are connected with a joggle, so that the winch stopping brake.
Double crosslinking drum 4 is connected with limit support 2 by tilting bearing, can eliminate like this by the concentricity of making and assembling produces.Limit support 2 and base 1 are by taper pin location, bolted connection.
The hydraulic power station of winch is connected with the hydraulic permeability reversing gear of winch by hydraulic tubing, and provide hydraulic power, hydraulic power becomes mechanical rotation power by HM Hydraulic Motor, transfer torque on the terminal big gear wheel through miniature gears, terminal big gear wheel and double crosslinking drum are fixed as one, and just can make steel rope regain simultaneously and emit by the positive and negative rotation of double crosslinking drum.
Certainly, those skilled in the art in the present technique field will be appreciated that, the foregoing description only is to be used for illustrating the present invention, and be not as limitation of the invention, as long as in connotation scope of the present invention, all will drop in the scope of claim of the present invention variation, the modification of the foregoing description.
