Description
Technical field
The lifting open-and-close mechanism of a kind of vertical-lifting movable bridge of the present invention, belongs to bridge field, particularly movable bridge.
Background technology
Movable bridge is a kind of bridge that bridge span structure can be moved or rotate, and is applicable to land or water transportation is very not busy but the river course of larger boats and ships of need opening the navigation or air flight or harbour.When boats and ships need by time, land transportation is broken off a friendship, movable bridge open; After boats and ships pass through, movable bridge closes, and land transportation recovers.Prior art vertical-lifting movable bridge adopts motor or hydraulic system to drive hoist engine usually, pulls wire rope by hoist engine, relies on the frictional force of wire rope and cable drum grooving to transmit power, makes bridge span structure increase or declines.The complex structure of this kind of vertical lift movable bridge, because driving-chain is long, gearratio is large, efficiency lowly causes that driving torque is large, gear reduction unit is heavy, expensive, and the space that gear reduction unit occupies is large, also has a great impact the outward appearance of bridge.Therefore, need development structure simple, stable and reliable for performance, and save space-efficient vertical-lifting movable bridge.
Summary of the invention
The object of the invention is to provide a kind of lifting open-and-close mechanism of vertical-lifting movable bridge, this lifting open-and-close mechanism adopts hydraulic pressure to be driving force, with simple structure, steadily run reliably, realize the high efficiency vertical-lifting opening and closing of movable bridge, further, this lifting open-and-close mechanism saves usage space, beautifies movable bridge outward appearance.
The lifting open-and-close mechanism of a kind of vertical-lifting movable bridge of the present invention, comprise hydraulic jack drive unit, wire rope cable drum, wire rope, disc-brake, balance weight body, upper locking mechanism, lower locking mechanism, centralising device and air buffer, described balance weight body is connected with bridge span structure by the wire rope around cable drum, is contained in bridge tower body; Cylinder body of hydraulic oil cylinder is located in balance weight body, cylinder piston rod and cable drum base hinged fixing; Disc-brake is arranged in cable drum edge, and the symmetrical correspondence of upper locking mechanism is arranged between bridge span structure bottom surface and tower body; The symmetrical correspondence of lower locking mechanism is arranged between bridge span structure bottom surface and bridge pier; Centralising device and snubber are separately positioned between bridge span structure bottom surface and bridge pier, control the lifting of bridge span structure smooth vertical by hydraulic jack push-and-pull balance weight body, realize the steadily efficient opening and closing of movable bridge.
Described upper locking mechanism is made up of dead bolt and lock, and its dead bolt and lock respectively symmetrical correspondence are arranged on bottom and the tower body side at bridge span structure two ends.
Described lower locking mechanism is made up of dead bolt and lock, and its dead bolt and lock respectively symmetrical correspondence are arranged on the bottom at bridge pier and bridge span structure two ends, has the self-locking inclined-plane of complementary angle each other between this dead bolt and lock.
Described centralising device is made up of upper bracket and undersetting, and symmetrical corresponding bottom and the bridge pier being arranged on bridge span structure two ends respectively of upper undersetting, has corresponding contact inclined-plane between upper undersetting.
Described air buffer is made up of cylinder, piston rod and base, and its cylinder, piston rod and base respectively correspondence are arranged on bridge span structure bottom surface and bridge pier upper surface.
The balance weight body that the present invention is arranged in tower body is connected with bridge span structure by the wire rope around cable drum, hydraulic jack is located in balance weight body, cylinder piston rod and cable drum base hinged fixing, control the vertical lift of bridge span structure by oil cylinder push-and-pull balance weight body and complete the opening and closing of bridge floor, when movable bridge movable bridge rises across Structure Quasi is standby, lower locking mechanism bolt retraction, open brake, bridge span structure enters can opening, start cylinder system, from the hydraulic oil of fuel tank, the rodless cavity of oil cylinder is entered from the bottom of balance weight body, control oil cylinder to extend, to piston thrust upwards, the power that balance weight body and hydraulic oil are produced is greater than the power that bridge span structure deadweight produces, thus balance weight body makes connected bridge span structure steadily rise by the wire rope walking around cable drum, after bridge span structure has risen, disk brake clamping steel wire rope reel, upper locking mechanism stretches out dead bolt, locking bridge span structure, when movable bridge bridge span structure declines closed, upper locking mechanism lock tongue shrinks, open brake, hydraulic oil from fuel tank enters the rod chamber of oil cylinder, namely oil cylinder is entered from the top of balance weight body, control oil cylinder to shrink, to the thrust that piston is downward, the power that now hydraulic oil and bridge span structure deadweight produce is greater than the power that balance weight body produces, balance weight body makes connected bridge span structure steadily decline by the wire rope walking around cable drum, in the steady ascending and descending process of bridge span structure, cable drum plays good guide effect, when bridge span structure drop to buffering piston bar contact with the bumper bracket on bridge pier time, snubber declines with bridge span structure, piston rod shrinks gradually, effectively slow down impact force when bridge span structure declines, centralising device is by contact of incline plane between upper and lower bearing simultaneously, the position that movable span falls is finely tuned, so that it drops down onto assigned address accurately, after bridge span structure has declined, disk brake clamping steel wire rope reel, lower locking mechanism dead bolt has stretched out, and reaches self-locking by the angle of slope between dead bolt and lower lock, and bridge span structure locking is entered can not opening.
The wire rope fitted through around cable drum due to balance weight body and hydraulic jack is connected with bridge span structure, ensure that the lifting of bridge span structure can even running, even if there is hydraulic jack failure conditions, hydraulic jack also can carry out buffering stably and run, and at this moment disc-brake clamping steel wire rope reel makes it stop operating; And air buffer, centralising device, lower locking mechanism also ensure that the safety of bridge span structure when transferring and stable, even if lower locking mechanism breaks down, also can the stretching out of Non-follow control dead bolt, making bridge span structure be in safe state, so just achieving bridge span structure safety and stable operation when being elevated.The present invention has and operates steadily, and operating efficiency is high, simple and reliable for structure, and cost and the feature such as operating cost is low, be widely used in various vertical-lifting movable bridge.
