Detailed description of the invention
Contrast accompanying drawing below, by the description to embodiment, the specific embodiment of the present invention is described in further detail.
Hydraulic lifting of the present invention dam, as shown in Figure 1, comprises movable dam plate 1, and movable dam plate 1 bottom is mobilizable being hinged, and can rotate along hinge spindle.Be provided with movable dam plate 1 and be the hydraulic pressure cylinder assembly that " people " word supports at the land side of movable dam plate 1, by the flexible elevating control of realizing movable dam plate of hydraulic cylinder.Hydraulic pressure cylinder assembly is made up of the single-unit hydraulic cylinder of multiple arranged, and single-unit hydraulic cylinder can ensure enough jacking oil pressure, jacking great efforts, and lifting response is rapidly.10 of the cylinder bodies of hydraulic cylinder interconnect and are integrated, and part hydraulic cylinder is provided with one end of piston rod 20 and upwards arranges, part hydraulic cylinder is provided with one end of piston rod 20 and arranges downwards.Piston rod 20 and the undersetting 4 arranged are downwards connected together through a hinge, and the piston rod 20 of upwards arranging is hinged with the upper bracket 5 being located on movable dam plate 1.Such arrangement not only can obtain very stable support effect but also reversed arrangement and can increase the jacking stroke of hydraulic cylinder, thereby ensures that movable dam plate 1 has larger scope of activities.
Hydraulic pressure cylinder assembly can be designed to be made up of multiple single-unit hydraulic cylinders according to actual hydraulic pressure, the arranged direction of its hydraulic cylinder piston rod 20 can be determined according to situation, is generally symmetrical, to obtain more stable support effect.The embodiment that the present invention provides, hydraulic pressure cylinder assembly comprises three hydraulic cylinders, middle master cylinder 2 and the auxiliary oil cylinder 3 of both sides, major-minor oil cylinder reversed arrangement.The piston rod 20 of master cylinder 2 is to lower support, and the piston rod 20 of two auxiliary oil cylinders 3 upwards supports, to obtain more stable support effect.The piston rod 20 of master cylinder 2 is connected by hinge axis with undersetting 4 downwards, and the piston rod 20 of both sides auxiliary oil cylinder 3 is connected by hinge axis with the upper bracket 5 on movable dam plate 1 correspondence position.Use leg-of-mutton stability of strutting system, can make the structure on the whole dam that hoists more firm, support more stable.
The hydraulic means on hydraulic lifting dam as shown in Figure 2, comprises the hydraulic pump, hydraulic cylinder and the oil sump tank that connect successively.Hydraulic cylinder support and connection are at movable dam plate 1 land side, and the hydraulic cylinder of hydraulic means comprises is located at middle master cylinder 2 and the auxiliary oil cylinder 3 of both sides, master cylinder 2 and auxiliary oil cylinder 3 reversed arrangement, and the cylinder body 10 of each hydraulic cylinder interconnects.The rod chamber of master cylinder 2 is communicated with by tube connector 7 respectively with the rod chamber of two auxiliary oil cylinders 3, and the rodless cavity of master cylinder 2 is communicated with by tube connector 7 respectively with the rodless cavity of two auxiliary oil cylinders 3.
In the hydraulic means on hydraulic lifting of the present invention dam, piston rod 20 ends of master cylinder 2 are provided with fuel feed hole and oil outlet, in piston rod 20, be provided with oil inlet passage and oil discharge passage, oil inlet passage is communicated with fuel feed hole, oil discharge passage and oil outlet are communicated with, each asphalt channel is all communicated with rodless cavity end with the rod chamber end of master cylinder 2, and same the stretching together that completes each oil cylinder by passing in and out oily cooperation contracted.Asphalt channel is located in piston rod 20, connect respectively the turnover oil duct being placed in piston rod 20 by the oil inlet and outlet of piston rod 20 ends, shorten the length of external oil pipe, simplify exterior line structure, pipeline maintains static relatively, can not move back and forth with oil cylinder is flexible, thus more stable, safe and reliable.Tube connector 7 adopts high pressure resistant seamless steel pipe, has abandoned the use of consistent lubricant pipe, avoids the risk of the leakage of oil oil impregnate causing because pipeline is aging, ensures durability and the safety of pipeline.
The lifting on hydraulic lifting dam can complete automatically by hydraulic control system, also can by operation setting hydraulic control system manual control valve realize pressure release and fall dam, to ensure the flood swelled in volume and the safety on the dam that hoists under power failure state again, also can be by the lifting on the float switch control dam of controlling hydraulic system be set in upper water.The course of work of hydraulic means is as follows: when water level to set position time; float switch is opened oil return line; the oil in both sides auxiliary oil cylinder 3 rodless cavities flows to master cylinder 2 rodless cavities by tube connector 7; thus the asphalt channel in master cylinder 2 piston rods 20 flows back to fuel tank; the rod chamber end oil-feed of each oil cylinder, hydraulic cylinder is reclaimed, movable dam plate 1 declines gradually; hydraulic cylinder also rotates around upper undersetting, drive movable dam plate 1 is packed up; On certain water level, need to rise dam retaining time, make oil pump pump oil by control system, the oil inlet passage in piston rod 20, in the rodless cavity of master cylinder 2, and passes into respectively by tube connector 7 in the rodless cavity of auxiliary oil cylinder 3, and oil pressure orders about piston rod 20 and stretches out.Oil in auxiliary oil cylinder 3 rod chambers of both sides is in tube connector 7 imports the rod chamber of master cylinder 2 simultaneously, flow back to fuel tank through drainback passage again, realize hydraulic cylinder jacking, promote movable dam plate 1 and gradually rise as rotating shaft taking the hinge axis of bottom, when rising, realize dash Water storage.
Movable dam plate can be designed to single fan dam plate or fan dam plate more according to river course developed width, respectively fanning between dam plate and seal to reach waterproof effect with rubber fastening band or other seal.For this longer movable dam plate 1, adopt hydraulic means is evenly spaced and is supported on movable dam plate 1 land side, every fan dam plate can be arranged two groups, three groups, four groups or more groups of hydraulic pressure cylinder assemblies according to its developed width or hydraulic pressure size.Gap size, arranging density are determined according to actual conditions, with stability and the safety of the dam entirety that ensures to hoist.
10 of the cylinder bodies of each major-minor oil cylinder connect as one by adpting flange 6, connect reliably and detachably, are convenient to carry out single cylinder maintain and replace.
Hydraulic lifting of the present invention dam, adopts hydraulic pressure cylinder assembly movable support dam plate 1, and multiple single-unit hydraulic cylinders ensure enough jacking oil pressure, and the landing response that hoists is fast; Multi-hydraulic-cylinder reversed arrangement increases jacking stroke; Use leg-of-mutton stability of strutting system, can make the structure on the whole dam that hoists more firm; Asphalt channel is arranged in the piston rod of master cylinder, simplifies exterior line structure, the use of having abandoned flexible pipe, and pipeline can not move back and forth along with the flexible of hydraulic cylinder, avoids pipeline aging and produce the risk of leakage of oil oil impregnate, safety and reliability; Compared with prior art, scientific structure, has realized in ensureing jacking stroke and has strengthened structure firmness in the present invention, lifting dynamics foot, and rapidly, flood fighting hydraulic impact is strong, safe, has stronger practicality in lifting dam response.
By reference to the accompanying drawings the present invention is exemplarily described above; but the present invention is not limited to aforesaid way; as long as adopt the improvement of the various unsubstantialities that method of the present invention design and technical scheme carry out or directly apply to other occasion, all drop in protection scope of the present invention.
