Detailed Description

In order that the above objects, features and advantages of the present disclosure may be more clearly understood, aspects of the present disclosure will be further described below. It should be noted that the embodiments and features of the embodiments of the present disclosure may be combined with each other without conflict.

In the following description, numerous specific details are set forth in order to provide a thorough understanding of the present disclosure, but the present disclosure may be practiced in other ways than those described herein; it is to be understood that the embodiments disclosed in the specification are only a few embodiments of the present disclosure, and not all embodiments.

Referring to fig. 1 to 4 and 11, the present disclosure provides a cantilever perfusion bridge fabrication machine, including a main beam 401, a basket hanging system and a traveling system, wherein a top front cross beam 501 is disposed at the front end of the main beam 401, the front end of the basket hanging system is suspended by the top front cross beam 501, the rear end of the basket hanging system is suspended by a bridge body, and hanging legs for supporting the rear end of the basket hanging system are further disposed at two sides of the main beam 401; the hanging basket system comprises an outer mold, the outer mold comprises a side mold 301 and a flange template arranged at the top end of the side mold 301, and the flange template is movably connected with the side mold 301 so as to enable the flange template to be in butt joint with or separated from the side mold 301; the walking system is used for supporting the main beam 401 and driving the main beam 401 to move.

In this embodiment, suspend the support in midair to the front end of hanging the basket system through girder 401, suspend the anchor in midair to the rear end of hanging the basket system through the bridge bottom plate to make the whole of hanging the basket system can be fixed for the bridge tip, thereby realize hanging the inside pouring of basket system, in order to realize the process of pouring to each section of bridge. It should be emphasized that the "front end" of the component in the present disclosure refers to a direction close to a construction section of a bridge, and the "rear end" of the component in the present disclosure refers to a direction close to a constructed section of the bridge.

When the next section of bridge is poured, the girder 401 needs to travel to the next working position, and the driving system can drive the girder 401 to travel longitudinally along the bridge. Since the main beam 401 inevitably drives the cradle system to travel when moving, the restraint between the rear end of the cradle system and the bridge body needs to be released first. After the restraint between the rear end of the cradle system and the bridge body is released, the restraint positions of the cradle system and the bridge body can be transferred to the hanging legs, so that the rear end of the cradle system is restrained again through the hanging legs.

This is intended to provide that the cradle system of the prior art is generally short in length and therefore relatively light in weight, but also results in a short distance per advance of the main beam 401 and thus a relatively long construction period. Therefore, in the scheme, the hanging legs are arranged, so that the length of the hanging basket system in the longitudinal direction of the bridge can be prolonged. This is because the rear end of hanging the basket system mainly supports through the bridge bottom plate originally, and the strong point is single, and the atress is also comparatively concentrated, consequently hangs the whole weight of basket system and should not increase to can restrict the length of hanging the basket system. In the above-mentioned embodiment, hang the leg through the setting and then can realize optimizing above-mentioned problem, hang the leg setting in the both sides of girder 401, and girder 401 is located the roof of bridge, consequently at first can shift the atress of hanging basket system rear end to the bridge roof on to make bridge roof and bottom plate support hanging basket system simultaneously, can effectively strengthen the fixed effect of hanging the basket, be convenient for increase the size of hanging basket system in order to improve the efficiency of construction. And when girder 401 antedisplacement, hang the leg and also can support the rear end of hanging the basket system, even like this hang the weight of basket system and increase, can not influence overall structure's stability and security yet. In the prior art, when the basket hanging system moves, the basket hanging system is generally supported only by the top front cross beam 501 of the main beam 401, so that the size of the basket hanging system cannot be increased, otherwise, the problem of installation stability of the basket hanging system may occur.

In the prior art, the outer mold is generally of an integrally formed structure, and because the cradle system needs to be lowered integrally when moving, the cradle system and the poured beam section are separated, and the outer mold is lowered at the same time. Because the bridge can set up the anchor block every other distance, also be in the detached state for making between external mold and the anchor block, then need make the external mold descend longer distance, even the whole longer distance that descends of basket system, can make like this and hang the holistic focus skew of basket system great, it is bigger than prior art to hang the whole size of basket system in this scheme in addition, can increase the burden of bridge and girder 401 like this undoubtedly, be unfavorable for maintaining the overall stability of structure.

In the embodiment, the outer die of the hanging basket system is further improved, the outer die is mainly split and comprises the side die 301 and the flange template, when the hanging basket system needs to move, the flange template can move outwards relative to the side die 301, so that the flange template is separated from the anchoring block, the descending distance of the hanging basket system can be reduced, the gravity center offset of the hanging basket system is small, and the stability of the whole structure of the hanging basket system in the moving process is effectively guaranteed.
