The utility model object realizes and being completed by following technical scheme:
A kind of device for bridge equal proportion supertronic integral jacking, be positioned at and treat jacking bridge bottom, it is characterized in that described device comprises hydraulic lifting oil cylinder, Convenient jack and PLC synchronous control system, described hydraulic lifting oil cylinder is connected with described PLC synchronous control system respectively with described Convenient jack, and wherein said hydraulic lifting oil cylinder pushing end has the ball head structure of variable-angle.
Described ball head structure comprises bulb and takes over a business, described bulb is hemispherical, described bulb upper surface with described in take over a business to be connected and fixed, the push rod top of described hydraulic lifting oil cylinder has the groove matching with the land portions shape of described bulb, described bulb and described push rod are connected and fixed by bolt, described bolt be positioned at the bolt hole matched in clearance on described bulb.
Describedly take over a business to be fixed on described bulb, its upper surface is horizontal plane.
The gap length of described matched in clearance is not more than 5 ° and is as the criterion to realize the corner of described bulb.
The utility model has the advantages that, by utilizing the jacking speed of PLC synchronous control system control Convenient jack and hydraulic lifting oil cylinder, can avoid the bridge collapse accident causing in the time that hydraulic lifting oil cylinder breaks down, improve safety, and make bridge realize equal proportion integral jacking; Be arranged at the ball head structure of the variable-angle at hydraulic lifting oil cylinder top, in jacking process, can keep vertical relation with bridge all the time, avoid due to the caused local stress of out of plumb relation between hydraulic lifting oil cylinder and bridge.
Brief description of the drawings
Fig. 1 is lift-up device schematic diagram in the utility model;
Fig. 2 is hydraulic lifting cylinder structure schematic diagram in the utility model.
Detailed description of the invention
Feature of the present utility model and other correlated characteristic are described in further detail by embodiment below in conjunction with accompanying drawing, so that technician's of the same trade understanding:
As Fig. 1-2, in figure, mark 1-10 is respectively: bridge 1, hydraulic lifting oil cylinder 2, Convenient jack 3, substructure 4, PLC synchronous control system 5, hole 6, top cover 7, bolt 8, bulb 9, push rod 10.
Embodiment: as shown in Figure 1, 2, the present embodiment is specifically related to a kind of device for bridge equal proportion supertronic integral jacking, this lift-up device is between bridge 1 and substructure 4, mainly formed by hydraulic lifting oil cylinder 2, Convenient jack 3 and PLC synchronous control system 5, hydraulic lifting oil cylinder 2 is connected with PLC synchronous control system 5 respectively with Convenient jack 3, and PLC synchronous control system 5 is for controlling the jacking speed of Convenient jack 3 with hydraulic lifting oil cylinder 2.
As shown in Figure 1, 2, hydraulic lifting oil cylinder 2 is active Lifting Equipment, and whole active jacking system is made up of some hydraulic lifting oil cylinders 2, so that powerful top lift to be provided.This active jacking system is connected by oil pipe, therefore each hydraulic lifting oil cylinder 2 can play a role jointly in the time of jacking.In the time arranging hydraulic lifting oil cylinder 2, must be symmetrically arranged, stressed evenly to ensure top bridge 1, prevent that top concrete local pressure from producing crack.Push rod 10 tops of hydraulic lifting oil cylinder 2 are with rotating ball head structure, this ball head structure comprises the bulb 9 being connected and fixed with push rod 10 and is fixed on the top cover 7 on bulb 9, this bulb 9 is hemispherical, there is the hemispherical groove matching with bulb 9 shapes at push rod 10 tops, bulb 9 is arranged in the hemispherical groove of push rod 10, and be connected and fixed through bolt 8, bolt 8 runs through in the hemispherical groove that screw 6 on bulb 9 enters push rod 10 and tightens fixing, it should be noted that, screw 6 apertures on bulb 9 are slightly larger than the diameter of bolt 8, be between bolt 8 and bulb 9, to be matched in clearance, so that bulb 9 has certain angular transformation space, the gap length of this matched in clearance is not more than 5 degree and is as the criterion to realize the corner of bulb 9.When jacking along with the variation of the gradient, hydraulic lifting oil cylinder 2 with top bridge 1 by the vertical out of plumb that becomes, now the ball head structure at hydraulic lifting oil cylinder 2 tops, along with the angle of the bulb 9 on cylinder top is adjusted in the variation of bridge 1 gradient automatically, makes the top cover 7 on bulb 9 perpendicular with bridge 1 all the time.The jack and the local stress of superstructure out of plumb to structure generation that adopt this hydraulic lifting oil cylinder 2 with ball head structure to solve to cause due to slope change in jacking process.
As shown in Figure 1, hydraulic lifting oil cylinder 2, in the time of jacking bridge, may occur letting out in hydraulic pressure, oil pipe burst etc. is unexpected, will cause immeasurable security incident, or even cave-in accident can occur bridge 1.Therefore be also provided with Convenient jack 3 in the present embodiment between bridge 1 and substructure 4, in order to still can effectively support top jacking bridge 1 in the time that the oil pressure of hydraulic lifting oil cylinder 2 suddenly disappears, to avoid 1 landing of top bridge.This Convenient jack 3 is carried by fro hydraulic driving machinery, and stroke can have 0mm～150mm electrodeless rotation, can meet the support needs that equal proportion supertronic jacking stroke does not wait.Convenient jack 3 inside also can adopt the mode of mechanical whorl to carry, and bear the load on top by the elastic deformation of mechanical whorl, while supposing that hydraulic jack goes wrong, can provide reliable mechanical support.
As shown in Figure 1, PLC synchronous control system 5 is connected with hydraulic lifting oil cylinder 2 and Convenient jack 3 simultaneously, and it is mainly made up of several parts such as computer control system (computer, computer software, operating desk, electric control box etc.), detecting sensors (displacement transducer, power sensor).PLC synchronous control system 5 is gathered jacking data and by Internet Transmission, is controlled both synchronizations of jacking up as calculated after the computational analysis of machine control system by the detecting sensor being arranged on hydraulic lifting oil cylinder 2 and Convenient jack 3.
As shown in Figure 1, 2, device in the present embodiment is specifically for bridge equal proportion supertronic integral jacking, therefore below the two ends of bridge 1, be provided with this device, control hydraulic lifting oil cylinder 2 jackings at bridge 1 two ends by PLC synchronous control system 5, in jacking process, adopt the consistent control principle of angular velocity, according to the difference of each pier jacking amount, equal proportion arranges the jacking velocity amplitude of each pier, reaches the object of all pier stud synchronizations of jacking up.
