The specific embodiment
Contrast accompanying drawing below, by the description to embodiment, the specific embodiment of the present utility model is described in further detail.
The utility model hydraulic lifting 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.Land side at movable dam plate 1 is provided with the hydraulic pressure cylinder assembly that is the support of " people " word with movable dam plate 1, by the flexible elevating control of realizing movable dam plate of hydraulic cylinder.Hydraulic pressure cylinder assembly consists of the single-unit hydraulic cylinder of a plurality of arranged, and single-unit hydraulic cylinder can guarantee 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 the jacking stroke that very stable support effect but also reversed arrangement can increase hydraulic cylinder, thereby guarantees that movable dam plate 1 has larger scope of activities.
According to actual hydraulic pressure, hydraulic pressure cylinder assembly can be designed to be comprised of a plurality of single-unit hydraulic cylinders, 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 utility model 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 is to upper support, 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 the utility model hydraulic lifting 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, oil inlet and outlet by piston rod 20 ends connects respectively the turnover oil duct being placed in piston rod 20, shortened 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, and the risk of the leakage of oil oil impregnate that causes because pipeline is aging is avoided in the use of having abandoned consistent lubricant pipe, guarantees 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 guarantee that the flood swelled in volume and the safety on the dam that hoists under power failure state again, the float switch that also can control by arranging hydraulic system in upper water is controlled the lifting on dam.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, in the time of need to rising dam retaining, by control system, make oil pump pump oil, 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 imports in the rod chamber of master cylinder 2 through tube connector 7 simultaneously, through drainback passage, flow back to fuel tank again, realize hydraulic cylinder jacking, the hinge axis that promotion movable dam plate 1 be take bottom rises gradually as rotating shaft, realizes dash Water storage in the time of rising.
According to river course developed width, movable dam plate can be designed to single fan dam plate or fan dam plate more, each is fanned between dam plate and seals 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 integral body that guarantees 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.
The utility model hydraulic lifting dam, adopts hydraulic pressure cylinder assembly movable support dam plate 1, and a plurality of single-unit hydraulic cylinders guarantee 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 when guaranteeing jacking stroke and has strengthened structure firmness the utility model, 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 utility model is exemplarily described above; but the utility model is not limited to aforesaid way; as long as adopt the improvement of the various unsubstantialities that method design of the present utility model and technical scheme carry out or directly apply to other occasion, all drop in protection domain of the present utility model.
