Abstract
The invention relates to a hydraulic oil tank driving rotating device. Two or more than two winches are arranged on a rotating axle of a crane wound roll. One oil tank is arranged on each of the winches. One end of each oil tank is hinged with the base of the crane and the other end of each oil tank is connected with the winch of the rotating axle. The invention overcomes the defects of high cost, no control of speed and only one speed adopted of the prior motor driving crane driving mechanism. The crane of large capacity adopts the rotation driven by hydraulic oil tank; therefore, the invention has the advantages of low lifting cost, capability of controlling rotating speed, steady lifting, reliable operation and convenient speed regulation.
Description
Technical field:
The invention belongs to hoisting crane drive configuration and hydraulic technique field.
Technology status:
At present, in the mechanism system at home and abroad, high rotating speed step-down rotating speed is arranged, rotation becomes straight line, the kinematic scheme that the straight line mutarotation changes.In hoisting crane used, most of employing electrical motor was a power, by retarder (driving system), drives reel, and goods is promoted.The lifting of low capacity has part directly to adopt HM Hydraulic Motor to drive; And the high capacity hoisting crane does not have the structure that adopts the hydraulic ram driven in rotation as yet, because that traditional driving system cost accounts for the hoisting crane cost is very most of, if it is higher to require to carry out the mechanical speed governors cost.And adopt hydraulic ram driven in rotation system can carry out capacity adjustment (arm of force adjustment, thrust adjustment), the speed adjustment.Make the more convenient and easy control that gets of mechanical movement change; The motion that the straight line mutarotation changes is used less in industrial system, but application is comparatively extensive in auto-industry, as automotive engine.In hoisting crane, its actuating device all is directly to be finished by electrical motor, by driving system (retarder and gear cluster), drives big gear wheel and reel and rotates, and steel rope on reel, is mentioned the goods of being carried.But in high-capacity hoisting crane lifting, the cost of driving system is higher, and speed is uncontrollable, can only adopt a speed.Adopt hydraulic ram driven in rotation system, can cost-cutting, realize rotating speed control.
Summary of the invention:
Purpose of the present invention provides a kind of low cost for the weak point that overcomes the existing actuation techniques existence of above-mentioned hoisting crane just, can realize the hoisting crane drive rotary device of hydraulic ram of rotating speed control.
The objective of the invention is to realize by following technical solution.
The turning cylinder of hoist roller is provided with two or more cranks, is respectively arranged with an oil cylinder on each crank; One end dumpling of every oil cylinder is connected on the crane foundation, and the other end is hinged and connected on the crank of turning cylinder.The present invention especially can adopt few to two oil cylinders as the hydraulic-driven slewing arrangement, and two oil cylinders when driving the hoisting crane turning cylinder still steadily, reliable, both reduced the complexity of control greatly, but can drive and control rotation very reposefully.
The invention has the beneficial effects as follows that the lifting cost is low, can realize rotating speed control on the high capacity hoisting crane, have lifting steadily, reliable, the speed governing of operation remarkable advantage easily.
Further set forth content of the present invention below in conjunction with drawings and Examples.
Description of drawings
Figure is hoisting crane pivot structure figure of the present invention.
The specific embodiment
As Fig. 1, the present invention specifically turning cylinder of hoist roller 3 is provided with two cranks, i.e. crank 2 and crank 4, and crank 2 is provided with an oil cylinder 1; The end dumpling that crank 4 is provided with 5, two oil cylinders of an oil cylinder is connected on the crane foundation, and the other end is hinged and connected on the crank of turning cylinder.
The principle of the invention is to change straight-line motion into garden Zhou Yundong, its method is that two or more cranks are arranged on the turning cylinder, between the crank the garden round angle be not equal to zero degree or 180 the degree, the crank that is the hoist roller axle is promoted with upper cylinder by two or two, one end dumpling of oil cylinder is connected on the basis, the other end is hinged and connected on the crank of turning cylinder, by the straight-line motion of oil cylinder, changes the garden Zhou Yundong of hoist roller axle into.In the Zhou Yundong of garden, there is dead unit problem in oil cylinder, and (promptly rotating the arm of force is zero situation, at this state, oil cylinder is in arbitrary position of high-low limit, by sensor notice hydraulic efficiency pressure system, change the sense of motion of oil cylinder), in adopting crank connecting, when the dead point appears in an oil cylinder, because the garden round angle of each crank is not equal to zero degree or 180 degree, the another oil cylinder can normal operation (dead point that this oil cylinder is avoided another is set), by two or two with the upper cylinder straight line push-and-pull campaign that hockets, realize the garden Zhou Yundong of reel, and the hocket instruction of straight line push-and-pull campaign of every oil cylinder is controlled by electronics or mechanical pick-up device.This invention realizes and control easily.
