Comprising accompanying drawing is further understand the utility model for providing, and they are included and form a application's part, and accompanying drawing shows embodiment of the present utility model, and plays the effect explaining the utility model principle together with this specification sheets.In accompanying drawing:
Fig. 1 shows the lateral plan of large-scale bridge crane heightening device of the present utility model.
Fig. 2 shows the front view of large-scale bridge crane heightening device of the present utility model.
Detailed description of the invention
With detailed reference to accompanying drawing, embodiment of the present utility model is described now.Now with detailed reference to preferred embodiment of the present utility model, its example is shown in the drawings.In the case of any possible, in all of the figs the identical mark of use is represented same or analogous part.In addition, although the term used in the utility model selects from public term, but some terms mentioned in the utility model specification sheets may be that applicant selects by his or her judgement, its detailed meanings illustrates in the relevant portion of description herein.In addition, require not only to pass through used actual terms, but the meaning that also will be contained by each term understands the utility model.
Fig. 1 and Fig. 2 shows large-scale bridge crane heightening device 100 of the present utility model from different angles respectively.
First with reference to figure 1, large-scale bridge crane heightening device 100 of the present utility model is applicable to large-scale bridge crane, this Large bridge winch to comprise less cross sill 1, perpendicular to this cross sill 1 arrange many root posts (being made up of 2-1 with 2-2 in Fig. 1) and be connected this column top contact crossbeam (not shown).Wherein, position (truncation surface 3 in the such as Fig. 1) place that this column contacts below crossbeam above this is truncated as upper pillar stand 2-1 and lower pillar stand 2-2.
As depicted in figs. 1 and 2, large-scale bridge crane heightening device 100 of the present utility model mainly comprise pressure beam 101, lifting bracket 102, outrigger 103, bracket structure 104, steel strand 105 and actuating device 106 form.
Pressure beam 101 is suitable for being pressed on this cross sill 1.Such as, this pressure beam 101 is scalable pressure beams.Preferred, this pressure beam 101 is made up of multiple block of plugging into, so that according to the gauge of this large-scale bridge crane and spreading or shortening.
In addition, this pressure beam 101 can comprise Hai Ceyaliang and land side pressure beam, wherein this Hai Ceyaliang be pressed in this large-scale bridge crane extra large side cross sill on and this land side pressure beam be pressed on side, the land cross sill of this large-scale bridge crane.
Compared with prior art, the pressure beam type stable form that the utility model proposes is not that the bridge crane resembling prior art contacts crossbeam and column butt welding, but be directly pressed in contact beam surface upper, then overcome by catching the bending moment come bottom bridge crane by stretching, to reach the stable effect of bridge crane bottom section.Its benefit is that volume is little, easy for installation, according to bridge crane gauge different arbitrarily spreading or shortening, can also provide stable support for lifting bracket while playing contact bridge crane bottom section.The program obtains checking in the lifting test of reality.
Lifting bracket 102 is vertically arranged on this pressure beam 101.This lifting bracket 102 is the main bodys of bearing weight, and its bottom is fixed on pressure beam 101.
Outrigger 103 is arranged perpendicular to this lifting bracket 102, and wherein one end of this outrigger 103 is provided with bracket structure 104.This bracket structure 104 is suitable for being connected with this upper pillar stand 2-1, drives this upper pillar stand 2-1 to move in the vertical direction to make this outrigger 103 via steel strand 105 under the driving of actuating device 106 (such as 350 tons of hydraulic rams).Preferably, it is inner that this outrigger 103 can be arranged at this lifting bracket 102, and its two ends are connected by the upper pillar stand 2-1 of bracket structure and large-scale bridge crane, as shown in Figure 2.
Steel strand 105 are ties of transmitting force in whole lifting.Such as, can form one group, parallel placement by every two steel strand 105, their one end and joist are by earth anchorage, and the other end, through oil cylinder, realizes moving up and down by anchor upper in oil cylinder, the effect of casting anchor.
In addition, another the focusing on adding high workload keeps the synchronism of oil cylinder in integrally-built stability and lifting process and stressed homogeneity.In order to the requirement meeting these two aspects of trying one's best, of the present utility model when designing lifting bracket structure, in order to make stressedly comparatively to concentrate on support body center, at pressing contact place design variable section, and in order to increase the resistance to overturning of lifting bracket, outside lifting bracket, be provided with stable support structure.Therefore, in the embodiment shown in Figure 2, large-scale bridge crane heightening device 100 can also arrange stable support structure 107 further.The side of this stable support structure 107 is fixed on this pressure beam 101, and the opposite side of this stable support structure 107 connects the top of this lifting bracket 102.For the ease of installing, dismantling, the coupling end of stable support structure 107 is designed to bolt connection mode.
On the other hand, in the process of increasing, have slippage dangerous because outrigger and bridge crane column are out of shape the inconsistent bridge crane (bracket structure) that makes, therefore the utility model also preferably may further include a shearing-resistance blocks 108.This shearing-resistance blocks 108 is arranged between the end of this outrigger 103 and this bracket structure 104, in order to prevent this bracket structure 104 due to the modification of outrigger 103 and upper pillar stand 2-1 and slippage.
In addition, in order to ensure the synchronism of the oil cylinder as actuating device, can rational height sensor.In order to cylinder force can be read, can also weight sensor be set; In order to ensure same group oil cylinder uniform force, the pumping plant that one drag two is mutually through can be set.
Large-scale bridge crane heightening device pressure beam of the present utility model is pressed on sea, side, land cross sill, and middle node can dock arbitrarily, install and stressed on by bridge crane gauge change impact, easy for installation; And a whole set of large-scale bridge crane heightening device only acts on the cross sill of bridge crane, does not account for quayage, does not act on harbour, to the basic no requirement (NR) of harbour, to be also that user is the most receptible raise mode for this.
Those skilled in the art can be obvious, can carry out various modifications and variations to above-mentioned exemplary embodiment of the present utility model and not depart from spirit and scope of the present utility model.Therefore, be intended to make the utility model to cover to drop within the scope of appended claims and equivalent arrangements thereof to amendment of the present utility model and modification.
