The shipping efficiency in the water conservancy such as lock navigation structure.
The technical scheme that this utility model is taken is：
A kind of vertical jacking activity highway bridge, including crossstructure, the arranged on left and right sides of the crossstructure bottom is provided with liquid
Pressure lifting body, the bent columns of the arranged on left and right sides of crossstructure are provided with horizontal lock mechanism.The hydraulic climbing mechanism includes
Jacking cylinder, hold-down support, the piston rod of jacking cylinder is connected with crossstructure by bearing.The horizontal lock mechanism bag
Cross cylinder, locking beam are included, the piston rod of cross cylinder is connected with locking beam by bearing.
The jacking cylinder is four groups, is symmetrically distributed in the crossstructure bottom left and right sides.
The jacking cylinder is symmetrically distributed in ship lift or ship lock crosses ship land route both sides.
The cross cylinder is four groups, is arranged on the left and right sides of crossstructure.
The locking beam bottom of the horizontal lock mechanism is provided with stainless steel guide rail.
The hold-down support does the second stage of embedded part and is fixed using steel plate and foundation bolt.
Device for detecting distance of travel is provided with the jacking cylinder.
The cross cylinder is provided with limit switch.
A kind of vertical jacking activity highway bridge of this utility model, by arranging vertical hydraulic climbing mechanism and crossstructure
Horizontal lock mechanism on the bent columns of the left and right sides, and hydraulic climbing mechanism and horizontal lock mechanism adopt Driven by Hydraulic Cylinder,
Transmission is fast, efficiency high.
The mode of four groups of jacking cylinders vertical lift, it is to avoid easy when oil cylinder stretches out when facing upward open type activity highway bridge and opening
The problem interferenceed with navigation ship, it is ensured that enough navigational clearances so that ship can pass through ship lift or ship lock.
Description of the drawings
Fig. 1 is main structure diagram of the present utility model.
Fig. 2 is overlooking the structure diagram of the present utility model.
Fig. 3 is horizontal lock mechanism structure schematic diagram of the present utility model.
In figure：Crossstructure 1, jacking cylinder 2, cross cylinder 3 locks beam 4, hold-down support 5, fluid pressure line and pumping plant 6,
Bent columns 7, stainless steel guide rail 8.
Specific embodiment
As shown in Fig. 1 ~ Fig. 3, a kind of vertical jacking activity highway bridge, mainly by crossstructure 1, hydraulic climbing mechanism, water
Flat locking mechanism, fluid pressure line and pumping plant 6, electrical control equipment, equipment embedded part etc. are constituted.
The arranged on left and right sides of the bottom of the crossstructure 1 is provided with hydraulic climbing mechanism, the framed bent of the arranged on left and right sides of crossstructure 1
Post 7 is provided with horizontal lock mechanism, the elevation of the horizontal lock mechanism on the bent columns 7, determines according to highest navigable stage
Navigational clearance determine.
The hydraulic climbing mechanism includes jacking cylinder 2, hold-down support 5, and hold-down support 5 is done using steel plate and foundation bolt
The second stage of embedded part is fixed, so during integral jacking is carried out to crossstructure 1, it is ensured that on hold-down support 5
Jacking cylinder 2 reliability.
The jacking cylinder 2 is four groups, and four groups of jacking cylinders 2 are symmetrically distributed in the bottom arranged on left and right sides of crossstructure 1.Top
Asynchronous error of the oil-lifting jar 2 in the range of total travel cannot be greater than 5mm.
Device for detecting distance of travel should be provided with jacking cylinder 2.When pontic needs jack-up, by fluid pressure line and pumping plant 6
Fuel feeding and controller control, the actions simultaneously of four groups of jacking cylinders 2 realize that crossstructure 1 is overall and steady rise.Due to jacking
Oil cylinder 2 is symmetrically distributed in ship lift（Or ship lock）Ship land route both sides are crossed, is rolled up relative to being driven using motor or hydraulic system originally
Machine is raised, is pulled for the drive mechanism of steel wire rope by hoist engine, efficiency high, equipment are simple, and relatively safe.Due to pontic
Structure weight itself is larger, and in lifting process repeatedly, steel wire rope is inevitably present traction gravity gravitation and friction, is using
During the phenomenon of fracture of wire in advance occurs, find easily to cause security incident not in time.
Further, because jacking cylinder 2 is vertical jack-up, it is to avoid the problem that mechanism interferences with navigation ship.
The horizontal lock mechanism includes cross cylinder 3, locking beam 4, and cross cylinder 3, level oil are provided with locking beam 4
Cylinder 3 is four groups, is arranged on the bent columns 7 of the left and right sides of crossstructure 1.The cross cylinder 3 of horizontal lock mechanism and hydraulic pressure
Run when jacking cylinder 2 is different, the operation between cross cylinder 3 should be provided with level detecting apparatus without synchronous requirement（Limit
Bit switch）.The piston rod of each cross cylinder 3 is connected with locking beam 4, and locking beam 4 bottom arranges stainless steel guide rail 8.Work as jacking
When crossstructure 1 is raised to correct position by oil cylinder 2, cross cylinder 3 will lock beam 4 and release along on stainless steel guide rail 8, and it is right to realize
The high-order support of crossstructure 1, it is ensured that ship is passed through.
Operation principle and process：As shown in figure 1, A is closed for movable highway bridge；B is in for movable highway bridge
Opening.When needing to open, 4 groups of jacking cylinders 2 rise crossstructure 1, when movable highway bridge jacking is to commitment positions
Locking beam 4 released by cross cylinder 3, it is to be checked measure locking beam 4 release in place after, by movable highway bridge be shelved on locking beam 4 on；
After ship is current to be finished, cross cylinder 3, jacking cylinder 2 are return successively, and movable highway bridge recovers land and passes through.Entirely rising
During drop, jacking cylinder 2, cross cylinder 3 are by hydraulic power unit operation, fluid pressure line and pumping plant 6, electrical control equipment equipment
In machine room disposed below.
