The specific embodiment
Below in conjunction with accompanying drawing, for example the present invention is described in more detail:
In conjunction with Fig. 1～5, in overline bridge 14 stair side erection bracket 2 for supporting elevation device 1, below bridge, holder part is respectively installed 10 small sheaves 3, select Fig. 1 a jacking system 1 in compare Kuan street, road surface and come overline bridge one side, select Fig. 1 b jacking system 1 to be arranged on an end of overline bridge 14, the compare Zhai street, ， road surface, both sides of bridge floor selects Fig. 1 c, at road both sides overline bridge 14 two ends, jacking system 1 is installed; The arm rest corresponding with 1 of jacking system above overline bridge 14, but the handrail door of switch is installed; Pulley 3 is installed above support 2, is noted when selecting Fig. 1 c mounting means, because rope 5 spans are excessive, for guaranteeing steel cable rope 5 safe handlings, one or more supports 2 should be installed in the middle of overline bridge 14, and pulley 3 is installed above it, for supporting steel cable rope 5; Near stair side and the body of a bridge, magnet 13 is installed above overline bridge 14, at the body of a bridge, is opened several steel plate draw-in grooves 12 as shown in Figure 4, for steel plate 16, insert and pin bay-lift 1, electromagnet 15 and steel plate 16 are installed on jacking system 1; To jacking system 1 installation rate control setup, pulley 3 is furnished with motor provides suitable power for it simultaneously; The slideway on support 2, with jacking system 1, slideway with it, to good, fixes steel cable rope 5 and jacking system, checks that each equipment all normally moves after errorless can bring into use; Under the pedestrian prepares on overline bridge during overline bridge, by descending button, locking device solution magnetic, because making fixation steel plate 16, action of the spring regains simultaneously, prepare on the ground upper overline bridge the time, by up button, locking device magnetisation, when arriving bridge floor, because the magnetic elevating device is adsorbed on bridge, spring ejects steel plate 16, inserts in the reserved steel plate draw-in groove 12 of the body of a bridge, fixes jacking system 1.When gravity installation 11 and control monitor unit 9 checks that whole jacking system is errorless, locking device will move the button instruction, bay-lift 1 carries out the lifting transportation automatically, in the whole service process, has speed control unit to be controlled the speed of jacking system 1, is the steadily operation of safety of device; When under overline bridge, bay-lift weight is greater than on overline bridge bay-lift weight, device warning is automatically carried signal to motor, by motor, for pulley, provides suitable power, and when bay-lift overload, device sends to overload and warns; While having the pedestrian not enter bay-lift or bay-lift door 10 fully not shut, the switching situation of control monitor unit control gate; Cooperation between periodic inspection slideway 2 and pulley 3, steel cable rope 5 and pulley 3 checks support 2 steadinesss simultaneously, and safely and effectively whether each device operation, regularly device is safeguarded.
The present invention as shown in Figure 1, comprises jacking system 1, support 2, pulley 3, slideway 6, can select Fig. 1 a, b mounting means when road surface is wider, can select Fig. 1 c mounting means when road surface is narrower; Reach as shown in Figure 2 the purpose of device lifting by pulley and slideway; Jacking system has following characteristics: gravity sensing device, locking device, shock absorption device are installed below bay-lift, control monitor unit and solar cell 8 are installed above the bay-lift door, device inside is provided with control panel, alarm device and warning, jacking system is furnished with speed control unit and motor simultaneously; Gravity sensing device has following characteristics: while by control program, making the weight of the bay-lift of overline bridge top be greater than the weight of overline bridge below bay-lift, this jacking system just can normally move, otherwise out of service, when exceeding predetermined weight, gives the alarm; Locking device has following characteristics: a side that can firmly be fixed on overline bridge while utilizing electromagnetism to make as shown in Figure 4 bay-lift be raised to the overline bridge top, control electromagnetism by shift knob and make the lifting of carrying out that bay-lift can be stable, utilize spring to eject steel plate simultaneously and insert body of a bridge hole as shown in Figure 4,5, pin jacking system; Shock absorption device has following characteristics: when bay-lift descends, play the effect of buffering, make pedestrian's safety and comfort when using this device; Whether control monitor unit has following characteristics: whether can identify the door of jacking system all to close, have the pedestrian to enter, guarantee that the pedestrian passes in and out safety; Speed control unit has feature: the speed in the time of can controlling jacking system and descend to rise makes the people can the upper and lower overline bridge of comfortable pulsation-free; Motor has feature: when jacking system sloping portion weight is less than rising part weight, for pulley provides power, device can normally be used.
At first, design and the installation of gravity sensing device are: the first, by electronic program, control, and can reasonably utilize and guarantee that overline bridge top bay-lift gravity is greater than the ground platform that falls, thereby bay-lift is moved up and down; The second, ensure jacking system safety, when surpassing maximum gross, give the alarm in time; The 3rd, when the overline bridge top, bay-lift gravity is less than the ground platform that falls, and for motor, carries signal, has motor to provide suitable dynamic for pulley, and jacking system can normally be moved.
Secondly, when locking device utilizes Electromagnetic Design to make bay-lift rise to the overline bridge top, can be parked in safely and effectively the overline bridge top, facilitate the pedestrian to pass in and out; When bay-lift is raised to the bridge floor electromagnetism and holds bay-lift, the steel plate of bay-lift below is ejected by spring, inserts the body of a bridge, fixedly bay-lift simultaneously; Remove galvanomagnetic effect when bay-lift descends, steel plate is recovered to bay-lift inside.
Again, the design of shock absorption device is to contact the impact caused with ground when descending with installing, and reduces acceleration due to gravity by the shock absorption device actv. human body is brought to uncomfortable impact, the safety when pedestrian who guarantees utilizes jacking system upper and lower and comfortable;
Then, the design of control monitor unit and installation guaranteed when the pedestrian passes in and out, and the situation such as prevent that door from closing is suddenly guaranteed the personal safety of pedestrian when the turnover bay-lift, and when the oscilaltion platform has all shut up the door carefully, during rerun procedure, bay-lift moves up and down.
In addition, jacking system is furnished with speed control system, and principle is identical with vertical lift, guarantees the steadily operation up and down of safety of jacking system.At support and jacking system both sides, slideway and small sheave are installed, are guaranteed speed and stability that jacking system moves up and down, occur " stuck " phenomenon while avoiding moving up and down.Simultaneously, when electric weight is not enough, the door of jacking system can be opened voluntarily by the pedestrian.The arm rest corresponding with the jacking system door above overline bridge, but the handrail door of switch is installed, when device rises to overline bridge, by the pedestrian, to be opened voluntarily, the turnover jacking system cuts out when device descends, protection pedestrains safety.
Finally, in the present invention, the required a small amount of electric weight of jacking system provides by solar cell, be provided with switch gate button, up-downgoing button, safety alarm and warning in jacking system inside, be equipped with safety hammer and aerial ladder simultaneously, when jacking system breaks down, for opening the bay-lift door, the safe escape crowd, by cooperatively interacting between each system, reach the conveying pedestrian's of safe and convenient purpose.
