Fig. 1 is the structural representation of the embodiment of the utility model;

Fig. 2 is the enlarged drawing at A place among Fig. 1.

The specific embodiment

The embodiment of the bank bridge of the utility model: as depicted in figs. 1 and 2; This bank bridge mainly is made up of the lifting mechanism that is provided with on bank crane span structure body and the bank crane span structure body; Bank crane span structure body has the crossbeam 1 that extends along fore-and-aft direction; Lifting mechanism mainly go up by two pairs of lower sheaves 301 that are provided with on two reels 2, driving, suspender 3, the suspender 3, driving that rear end that be provided with and lower sheave 301 cooresponding two pairs of top sheaves 401, crossbeam 1 is provided with reel 2 cooresponding two pairs of back pulleys 101, reach crossbeam 1 the front end setting with back pulley 101 cooresponding two pairs of front wheels 102; Four steel ropes 5 are pile warp back pulley 101, top sheave 401, lower sheave 301, top sheave 401 and front wheel 102 successively all; The rear end that is in two inboard steel ropes 5 in four steel ropes 5 is separately fixed on the reel 2, and front end interconnects; The rear end that is in two steel ropes 5 in the outside also is separately fixed on the reel 2; Front end interconnects; About the concrete winding structure of steel rope,, application number specifies in being the prospectus of 200820215351.4 Chinese utility model patent, therefore no longer detail.Wherein, Two pairs of back pulleys 101 are installed in respectively on the Hydranlic tensioner 6 that is in crossbeam 1 back-end location that is provided with on the two opposite bank crane span structure bodies; This Hydranlic tensioner 6 mainly by be hinged on swing arm 601 on the bank crane span structure body, and the hydraulic actuating cylinder of laying along fore-and-aft direction that is provided with of crossbeam 1 rear end constitute; This swing arm 601 has can be at the projecting end of fore-and-aft direction swing, and back pulley 101 just is installed on the projecting end of this swing arm 601; The cylinder body of this hydraulic actuating cylinder is hinged on crossbeam 1 rear end, and the piston rod of hydraulic actuating cylinder is hinged on the projecting end of swing arm 601, and control linkage has pumping plant on the hydraulic actuating cylinder.

Wherein, String is provided with unloading valve between pumping plant and the hydraulic actuating cylinder; The input end of this unloading valve is connected with hydraulic actuating cylinder, and the mouth of unloading valve is connected with pumping plant, and between unloading valve and hydraulic actuating cylinder, is provided with pressure relay; The signal input part control linkage of pressure relay is on hydraulic actuating cylinder, and the signal output part control linkage of pressure relay is on unloading valve.

Further, the distance between two top sheaves 401 of corresponding centering of top sheave 401 and lower sheave 301 is greater than the distance between two lower sheaves 301.

In addition, be connected with the PLC controller on the pressure relay, this PLC controller has with the mouth bonded assembly input end of pressure relay and is used for and controls the mouth of the lifting motor control linkage of lifting mechanism.

In addition, in two pairs of hydraulic actuating cylinders, be communicated with through the damping arrangement that is provided with between the two in twos.

In use, this bank bridge can be accomplished and hang the cabin protection, suspender verts and suspender subtracts three functions of shaking, and three's principle of work is following:

Hang the principle of work of cabin protection:

When bank bridge normal operation, the piston rod of four hydraulic actuating cylinders is in the state of stretching out, and the squeese pressure when receiving steel rope 5 tensionings; When taking place to hang the cabin; The pulling force of steel rope 5 can increase moment; Thereby make the oil pressure of the interior hydraulic oil of hydraulic actuating cylinder to increase accordingly; When the setting pressure of the unloading valve of setting on the pressure overpressure relay of hydraulic oil, the signal that pressure relay feeds back on the PLC controller can make PLC controller control lifting motor quit work, thereby makes lifting mechanism quit work; Simultaneously; Pressure relay can be controlled unloading valve and open, and hydraulic oil can be back in the pumping plant through unloading valve, and the piston rod of hydraulic actuating cylinder also can cooresponding rollback (shown in dotted line among Fig. 2); Thereby make the lifting mechanism impulsive force that steel rope 5 produces when quitting work be released through the backflow of hydraulic oil; Just make the huge inertial impact force of suspender when stopping to hoist absorbed by hydraulic oil, thereby when realizing that lifting motor quits work, " soft landing " of lifting mechanism.Through the test of many times checking, from the bank bridge cabin to lifting mechanism taking place to hang shuts down, whole process estimates that the time spent is between 0.3 second to 0.5 second, thereby makes bank bridge complete machine have failure-free safety guard-safeguard more.

The principle of work that suspender verts:

When the piston rod of two pairs of hydraulic actuating cylinders all during protruding equal length, the mode of operation of four steel ropes 5 is identical; When the piston rod of pair of hydraulic cylinders advances backward; Another is during to the piston rod rollback of hydraulic actuating cylinder; Advance the back pulley of a side to be raised through the side of rope traction suspender, the cooresponding opposite side of suspender can be put down under the effect of back pulley, thereby verts about making suspender 3 produce; When in two pairs of back pulleys 101 with forward or lean on after two promotions of back pulley 101 of two lower sheaves 301 at hydraulic actuating cylinder under when advancing backward, cooresponding two other back pulley 101 rollbacks, thus make suspender 3 vert before and after producing.

Again since in the every pair of top sheave 401 spacing between two top sheaves 401 be greater than the spacing between cooresponding two lower sheaves 301; Thereby make and have an angle between two steel ropes that are in the same end of suspender; Thereby make suspender each steel rope when normal operation that the component of an application force forward or backward arranged suspender; And then under the traction of cooresponding back pulley, the component on the cooresponding steel rope can be increased or reduced, make suspender produce to revolve before cooresponding or after revolve.

Suspender subtracts the principle of work of shaking:

When suspender 3 generations are waved; Suspender can be with 5 tensions of cooresponding two steel ropes, and make two outer two steel ropes 5 lax, thereby make the pressure reduction of generation between any two of two pairs of hydraulic actuating cylinders 601; When pressure reduction occurs; Hydraulic oil can flow into the hydraulic actuating cylinder of low tension terminal through damping arrangement from the hydraulic actuating cylinder of high-pressure side, thereby makes suspender 3 be converted into the heat energy that hydraulic oil produces at the kinetic energy and the potential energy of the process of waving when flowing through damping arrangement, and then reaches suspender and subtract the purpose of shaking.

In the above-described embodiments; The coiling of steel rope and application number are that the coiling of steel rope is consistent in the jack up unit of disclosed bank bridge in the prospectus of 200820215351.4 Chinese utility model patent in the jack up unit on this bank bridge; In other embodiments; The coiling of steel rope also can be other winding modes in the jack up unit of bank bridge, and for example application number is the winding mode of disclosed bank bridge jack up unit in the prospectus of 200920015764.2 Chinese utility model patent.

The bank bridge of the utility model is with the embodiment of Hydranlic tensioner: the concrete structure of this Hydranlic tensioner and principle of work be explanation in the above-described embodiments, therefore no longer details in the present embodiment.
