Abstract
The utility model relates to a full balance hydraulic mechanism for lifting ships vertically, which comprises a ship supporting box. The utility model is characterized in that the periphery of the ship supporting box is respectively provided with four sets of hydraulic press ship mechanisms; the hydraulic press ship mechanisms comprise two hydraulic inserting cylinders which are arranged in horizontal opposite directions, and a main hydraulic cylinder which is vertically arranged in the lower part of the hydraulic inserting cylinder by a connecting socket and a guide post; the hydraulic press ship mechanisms are combined with the ship supporting box by a drive support frame which is combined with the cylinder wall of the main hydraulic cylinder; both sides of each set of hydraulic press ship mechanism are provided with limit rack bars which are matched with the inserting teeth of the front end of the piston rod of the hydraulic inserting cylinder.
Description
The utility model relates to a kind of vertical ship lift, relates to a kind of full-balanced hydraulic launching vertically ship specifically.
The vertical ship lift that is widely used at present in the big-and-middle-sized key water control project navigation system mostly is following two kinds of forms: i.e. full-balance vertical ship lift and launching vertically ship.
The full-balance vertical ship lift is by boat supporting case, promotes main frame, and balance suspension system and other auxiliary equipment are formed.Because full-balance vertical ship lift gravitational equilibrium heavily reaches the gross weight that the heavy sum of torque balance equals boat supporting case, the inertia force that the lifting main frame only need overcome institute's frictional force in the motion, air resistance and acceleration (or deceleration) generation gets final product.So power draw is less, the relevant device investment is also few.The major defect of full-balance vertical ship lift is the bigger transportation river course of level of tail water luffing, incompatibility dam district, this is because of and the investment greatly of metal construction opening and closing device heavy except that the tail-bay civil works, because the tail-bay service gate needs more continually to open and close having under the pressure condition, adjust the door position, the reliability of gate sealing is difficult to guarantee technically, the damage of the antipriming maintenance that need bring to is difficult for guaranteeing long-term normal, the safe operation of ship lift.
Launching vertically ship is by boat supporting case, promotes main frame, and balance suspension system and other auxiliary equipment are formed.The launching vertically ship major advantage is the transportation river course that is applicable to that dam district level of tail water luffing is bigger.Because tail-bay only establishes the maintenance Stoplog gate, need not establish service gate, dock requirement with not having between the ship case, saved the ship case the holding out against, clamp, seal and fill auxiliary movement such as sluicing of tail-bay, navigation is fast saved time.Its main weak point is: directly descend water for making boat supporting case, it is heavy that the balance suspension system is only established torque balance, strengthened the braking moment of main frame, and Electric Traction power strengthens, and cost is also higher, and corresponding annual operating cost is also considerable.
It is a kind of on the basis that keeps constant and its advantage of full-balance vertical ship lift basic structure that the purpose of this utility model provides with regard to being to overcome above-mentioned weak point of the prior art, by the delay unloading a ship mode of mechanism of increase, realize that both can reduce boats and ships crosses the dam program, can improve operational reliability again, and have the full-balanced hydraulic launching vertically ship that not influenced by lower approach than Large Water luffing and rate of change.
The purpose of this utility model can adopt following measure to realize:
Full-balanced hydraulic launching vertically ship of the present utility model comprises boat supporting case, is respectively arranged with the quadruplet hydraulic pressure mechanism of delaying unloading a ship at the periphery of described boat supporting case; The described hydraulic pressure hydraulic pressure that mechanism comprises that two levels install in opposite directions of delaying unloading a ship inserts cylinder, vertically is installed in the main hydraulic cylinder that hydraulic pressure inserts the cylinder below by Connection Block, lead; Described hydraulic pressure is delayed unloading a ship mechanism by combining with boat supporting case with driving arm that the main hydraulic cylinder casing wall combines; Be provided with hydraulic pressure and insert the spacing tooth bar that the insertion tooth of piston rod front end in the cylinder matches in the delay unloading a ship both sides of mechanism of every cover hydraulic pressure.
Advantage of the present utility model is that both can reduce boats and ships crosses the dam program, can improve operational reliability again, and has the advantage that not influenced than Large Water luffing and rate of change by lower approach; Its investment and the more preceding two kinds of ship lifts of operating cost all reduce significantly in addition, can reduce total investment expenses 10～20%.
The drawing of accompanying drawing is described as follows:
Fig. 1 is a boat supporting case front view in the utility model.
Fig. 2 is the vertical view of Fig. 1.
Fig. 3 is the delay unloading a ship front view of mechanism of hydraulic pressure among Fig. 1.
The utility model is done with detailed description below with reference to embodiment (accompanying drawing).
As shown in the figure, the utility model is respectively arranged with the quadruplet hydraulic pressure mechanism (1) of delaying unloading a ship at boat supporting case (2) periphery of full-balanced hydraulic launching vertically ship; The described hydraulic pressure hydraulic pressure that mechanism (1) comprises that two levels install in opposite directions of delaying unloading a ship inserts cylinder (4), vertically is installed in the main hydraulic cylinder (8) that hydraulic pressure inserts the cylinder below by Connection Block (5), lead (9); Described hydraulic pressure is delayed unloading a ship mechanism by combining with boat supporting case (2) with driving arm (7) that main hydraulic cylinder (8) casing wall combines; Be provided with hydraulic pressure and insert the spacing tooth bar (6) that the insertion tooth (3) of piston rod front end in the cylinder (4) matches in the delay unloading a ship both sides (being corresponding building structure position) of mechanism of every cover hydraulic pressure.
Operating principle of the present utility model is as follows:
During work (the following some distances of the boat supporting case bottom contact this moment water surface), earlier hydraulic pressure being inserted cylinder stretches out, make the respective teeth root engagement of inserting tooth and spacing tooth bar, start main hydraulic cylinder then, delay unloading a ship by force downwards by the driving arm that combines with the main hydraulic cylinder casing wall, (water level and the level of tail water are made even in the boat supporting case to requiring water level to make its entry.Realize that thus boats and ships go into to sail boat supporting case and sail out of the function of boat supporting case.
