Abstract
The invention discloses a kind of winch hydraulic multi-motor actuating device, belong to hydraulic wireline winch technical field, comprise a big gear wheel (1), the winch drum (4) be connected with big gear wheel (1), also comprise at least two miniature gearss (2) engaged with big gear wheel (1), each miniature gears (2) correspondence connects a HM Hydraulic Motor (3), and each HM Hydraulic Motor (3) is connected in parallel to bidirectional hydraulic lock (6) by pipeline (5), bidirectional hydraulic lock (6) connection winch hydraulic efficiency pressure system.The present invention adopts two HM Hydraulic Motor to drive a big gear wheel to realize larger pulling force by the miniature gears of correspondence simultaneously, and multiple HM Hydraulic Motor connects bidirectional hydraulic lock by parallel pipeline, and prevent winch sport car by bidirectional hydraulic lock locking HM Hydraulic Motor, mechanical efficiency is high, with low cost, structure is simple, and maintenance and repair is convenient.
Description
Technical field
The present invention relates to a kind of winch hydraulic multi-motor actuating device, on the winch that the fields such as belt conveyer, vehicle for construction, yard craft that are mainly used in use, belong to hydraulic wireline winch technical field.
Background technology
Hydraulic wireline winch is generally applied in boats and ships, construction machinery and equipment, belt conveyer, vehicle for construction.The hydraulic wireline winch that existing market exists generally adopts single motor to drive, and realizes stronger pulling force by speed reduction gearing, and prevent-moving car design also adopts drg or worm gear box mostly.The problems such as so, when realizing larger pulling force under certain scantling of structure, just face speed reduction gearing complexity, manufacturing cost is high, and maintenance maintenance is inconvenient; Equally, prevent-moving car drg also also exists mechanism's complexity, high in cost of production problem defect, and the mechanical efficiency of worm gear box is low, and actual value has about 50%, restriction work efficiency.
Summary of the invention
For above-mentioned existing technical matters, the invention provides a kind of winch hydraulic multi-motor actuating device, improve to reach mechanical efficiency, cheap for manufacturing cost, structure is simple, and maintenance and repair is object easily.
The present invention for achieving the above object, be achieved through the following technical solutions: a kind of winch hydraulic multi-motor actuating device, comprise a big gear wheel, the winch drum be connected with big gear wheel, also comprise at least two miniature gearss engaged with big gear wheel, each miniature gears correspondence connects a HM Hydraulic Motor, and each HM Hydraulic Motor is connected in parallel to bidirectional hydraulic lock by pipeline, bidirectional hydraulic lock connection winch hydraulic efficiency pressure system.
The invention has the beneficial effects as follows: adopt two or more HM Hydraulic Motor to drive a big gear wheel to realize larger propulsive effort by the miniature gears of correspondence simultaneously, and multiple HM Hydraulic Motor connects bidirectional hydraulic lock by parallel pipeline, and prevent winch sport car by bidirectional hydraulic lock locking HM Hydraulic Motor.Multiple motor synchronous drives and not only enables hydraulic wireline winch realize comparatively large driving force, effectively can also prevent sport car, improves mechanical efficiency.Meanwhile, speed reduction gearing is simple, and reduce manufacturing cost and the maintenance and repair expense of hydraulic wireline winch, maintenance and repair is more convenient.
Accompanying drawing explanation
Fig. 1 is structure birds-eye view of the present invention.
In figure: 1, big gear wheel, 2, miniature gears, 3, HM Hydraulic Motor, 4, winch drum, 5, pipeline, 6, bidirectional hydraulic lock.
Detailed description of the invention
Below in conjunction with accompanying drawing, the invention will be further described.
As shown in Figure 1, the present invention includes a big gear wheel 1, the winch drum 4 be connected with big gear wheel 1, also comprise at least two miniature gearss 2 engaged with big gear wheel 1, each miniature gears 2 correspondence connects a HM Hydraulic Motor 3, each HM Hydraulic Motor 3 is connected in parallel to bidirectional hydraulic lock 6 by pipeline 5, bidirectional hydraulic lock 6 connection winch hydraulic efficiency pressure system.Further, be connected in parallel and braking effect for coordinating, HM Hydraulic Motor 3 adopts cycloid hydraulic motor.
Principle of work of the present invention is: each miniature gears 2 is by HM Hydraulic Motor 3 individual drive, and the miniature gears 2 that at least two fluid motor-driven connect separately, engages to drive the winch drum 4 be connected with big gear wheel 1 by big gear wheel 1 and miniature gears 2.And two or more HM Hydraulic Motor 3 is connected in parallel to bidirectional hydraulic lock 6 by pipeline, extraordinary synchronous effect and prevent-moving car effect can be realized.Wherein bidirectional hydraulic lock 6 is widely used in the hydraulic wireline winch in the machineries such as engineering transportation lifting, as the winch etc. of the Hydranlic tensioner of belt feeder, when its principle of work is an oil pocket forward oil-feed, another chamber is oppositely fuel-displaced, vice versa, when two chamber forward not oil-feeds, oppositely also obstructed, do not disturb by external load, play the effect of lock.
Working process of the present invention is: select two miniature gearss 2 and two HM Hydraulic Motor 3 during concrete enforcement.When winch hydraulic system gives two HM Hydraulic Motor 3 fuel feeding by bidirectional hydraulic lock 6, two HM Hydraulic Motor 3 drive corresponding miniature gears 2 to rotate respectively, two miniature gearss 2 engage big gear wheel 1 simultaneously, moment of torsion are passed to winch drum 4, thus drive winch drum 4 to rotate; When winch hydraulic system stop control lever, the oil circuit of two HM Hydraulic Motor 3 can be locked at once by bidirectional hydraulic lock 6, two HM Hydraulic Motor 3 are all braked, thus reach locking winch to prevent the effect of winch sport car.
Claims (1)
