As shown in figure 1, a bridge steel reinforcement framework's hoist device include hoist and mount crossbeam, lifting rope 3 and hoist and mount rope 10.
Wherein, the lower extreme of lifting rope 3 connect in the top of hoist and mount crossbeam, the upper end of lifting rope 3 then is connected with hoisting accessory like the couple of tower crane.
The upper end of hoisting rope 10 connect in the bottom of hoist and mount crossbeam, the lower extreme of hoisting rope 10 then is connected with the framework of steel reinforcement of treating the hoist and mount.
In order to realize the hoist and mount to big long framework, in this application embodiment, set up the hoist and mount crossbeam into to constitute by a plurality of spandrel girders that link to each other end to end in proper order, so, alright select according to the concrete length of the framework of steel reinforcement that will hoist and connect how many spandrel girders, make this application embodiment hoist device use more nimble, applicable in the hoist and mount of the framework of steel reinforcement of arbitrary length, even the framework of steel reinforcement of length more than 50m also can hoist, its hoist and mount performance has far exceeded other types's hoist device among the prior art. The embodiment of the application obviously improves the construction efficiency and can ensure the construction quality.
Simultaneously, can set up to dismantling the connection between many spandrel girders to in the length of change hoist and mount crossbeam at any time. For example, bolt connecting holes can be formed in the connecting ends of two adjacent bearing beams. And then connecting two adjacent bearing beams together by using bolts 7 through bolt connecting holes on the connecting ends of the two adjacent bearing beams. The number of the bolt connecting holes and the number of the bolts 7 to be used can be set as required to ensure the connecting strength. Generally, the more the number of bolt coupling holes and bolts 7 is provided, the more firmly the coupling thereof is. However, the number of the bolt connecting holes and the bolts 7 is too large, so that the dismounting process of the hoisting beam becomes complicated, and therefore, the bolt connecting holes and the bolts 7 are selected and arranged 6 to balance the requirements of the bolt connecting holes and the bolts 7 according to actual conditions.
When the hoisting device is assembled, certain assembling precision is ensured. Among these assembly accuracies, the straightness of the hoisting beam is a relatively important parameter. If the straightness accuracy of hoist and mount crossbeam is not high enough, appear inclining when leading to hoist and mount framework of steel reinforcement easily, the framework of steel reinforcement atress is uneven when hoist and mount, easily takes place to warp. In order to avoid the above defects, in the embodiments of the present application, a plurality of load-bearing beams for hoisting a cross beam may be disposed in a vertical plane, that is, the plurality of load-bearing beams are substantially located on a straight line. Therefore, the length direction of the hoisting beam is basically parallel to the length direction of the steel reinforcement framework when the steel reinforcement framework is hoisted, so that the hoisting stress of the steel reinforcement framework is more balanced, and the deformation of the steel reinforcement framework during hoisting is reduced.
In some embodiments, in order to reduce the deformation of the hoisting beam during hoisting, the structure of the hoisting beam needs to be designed to ensure that the stress is more balanced at each part of the hoisting beam. Therefore, the embodiment of the application considers that the hoisting cross beam is designed into a structural form of one main bearing beam 1 and even number of auxiliary bearing beams 2. The even number of the auxiliary bearing beams 2 are respectively and symmetrically connected to the two ends of the main bearing beam 1, namely the auxiliary bearing beams 2 at the two ends of the main bearing beam 1 are symmetrically arranged about the symmetrical plane 4 at the center of the main bearing beam 1, so that the stress of the left part and the right part of the whole hoisting cross beam is completely the same, and the condition that one side of the hoisting cross beam is too large in stress and is bent and deformed can not occur.
Meanwhile, the symmetrical arrangement of the auxiliary bearing beams 2 also means that the structures of each auxiliary bearing beam 2 are completely the same or at least two auxiliary bearing beams 2 are the same, so that the manufacturing difficulty can be reduced during processing and manufacturing.
In order to facilitate the connection between the lifting rope 3 and the lifting beam, the lifting device further comprises an upper lifting mechanism. The upper hoisting mechanism comprises an upper connecting plate 5 and an upper hook 6. The upper connecting plate 5 is connected to the top of the hoisting crossbeam. The upper hook 6 is connected to the upper connecting plate 5. One end of the lifting rope 3 is connected with the upper hook 6. The hoisting mechanism is arranged to enable an accurate connection point to be arranged between the hoisting rope 3 and the hoisting beam, and the position of the hoisting mechanism can be designed to enable the tension of the hoisting rope 3 on the hoisting beam to reach a preset standard, so that the stress of the hoisting beam is more balanced.
In some embodiments, the top of each of the load-bearing beams is provided with at least one of the hoisting mechanisms. The lifting rope 3 is connected with each lifting mechanism correspondingly. Therefore, each bearing beam is provided with at least one lifting rope 3 for exerting pulling force on the bearing beam, so that all parts of the whole lifting beam are stressed, and the situation of stress concentration cannot occur.
Meanwhile, the lifting rope 3 has certain requirements: it is not allowed that one lifting rope 3 separately lifts both ends, and each lifting rope 3 must be used separately.
In order to facilitate the connection between the hoisting rope 10 and the hoisting beam, the hoisting device in the embodiment of the application further comprises a lower hoisting mechanism. And the lower hoisting mechanism comprises a lower connecting plate 8 and a lower hook 9. The lower connecting plate 8 is connected to the bottom of the hoisting beam. The lower hook 9 is connected to the lower connecting plate 8. One end of the hoisting rope 10 is connected with the lower hook 9. The lower hoisting mechanism and the upper hoisting mechanism have similar functions and are used for enabling stress points to be more accurate and reliable.
In order to enable the stress of the steel bar framework to be more balanced when the steel bar framework is hoisted, at least one lower hoisting mechanism can be arranged at the bottom of each bearing beam. And then, one lifting rope 10 is connected corresponding to each lower lifting mechanism. Therefore, a plurality of hoisting stress points are arranged between the hoisting cross beam and the steel bar framework, the steel bar framework is subjected to hoisting force everywhere, the stress of the steel bar framework is dispersed and balanced, and the stress concentration condition cannot occur, so that the steel bar framework is not easy to bend and deform.
When hoisting linear type framework of steel reinforcement, can consider all the bottom hoist and mount end of hoist and mount rope 10 sets up in a horizontal plane, and hoist and mount crossbeam and framework of steel reinforcement are the parallel state substantially to guarantee that both atresss dispersion and equilibrium, thereby avoid sliding, heeling etc. and can lead to lifting by crane the equipment and take place the emergence of rocking the situation.
In practical use, some cautions capable of improving the use effect exist, for example, the hoisting position of the hoisting rope 10 (namely the setting position of the lower hoisting mechanism) can be adjusted according to the length of the steel reinforcement framework, and two hoisting ropes 10 are always arranged on the main bearing beam 1. No matter 2 auxiliary bearing beams 2 exist, or 4 or 6 auxiliary bearing beams 2 exist, the hoisting ropes 10 are arranged at the end heads of the auxiliary bearing beams 2 to balance the stress, but the hoisting ropes 3 are not allowed to be connected at the end heads of the auxiliary bearing beams 2.
The technical features of the embodiments described above may be arbitrarily combined, and for the sake of brevity, all possible combinations of the technical features in the embodiments described above are not described, but should be considered as being within the scope of the present specification as long as there is no contradiction between the combinations of the technical features.
The above preferred embodiments should not be considered as limiting the invention, which is intended to be limited only by the scope of the appended claims. It will be apparent to those skilled in the art that various modifications and enhancements can be made without departing from the spirit and scope of the invention, and such modifications and enhancements are intended to be within the scope of the invention.
