Description

Technical Field

[0001] The utility model belongs to the technical field of prefabricated box beams, and in particular relates to an inner mold removal platform based on a prefabricated box beam movable pedestal production line. Background Art

[0002] Precast box girders are a modern concrete structural product characterized by environmental friendliness and ecological conservation. To achieve continuous production of precast box girders, a mobile pedestal production line was developed, featuring streamlined and automated production. Compared to traditional cast-in-place beam production, this significantly improves production efficiency, meeting the construction goals of high efficiency, high quality, and high safety.

[0003] During the production and forming process of the box girder, the concrete formwork needs to be removed. The concrete formwork includes the outer formwork and the inner formwork of the box girder. The traditional box girder inner formwork needs to be manually inserted into the formwork for removal and lifting, which involves long-term manual mold insertion operations and has a relatively high safety risk. With the popularization of mechanization, the existing technology also discloses the use of mechanical devices to remove the inner formwork. For example, the patent with publication number CN204725644U discloses a prefabricated box girder inner formwork integral extraction device, including a hydraulic system, an inner formwork push rod, an inner formwork support rod, a linkage rod, a winch, and a demolding platform. The inner formwork push rod and the inner formwork support rod are removed, the hydraulic system is turned on, and the linkage rod is pushed to shrink the inner formwork and fold inward, separating the formwork from the concrete. The inner formwork is pulled out as a whole by a winch, and the pulled-out inner formwork is placed on the demolding platform to facilitate the reassembly of the inner formwork. The use of the machine provided by this patent can effectively improve production efficiency, reduce production costs, improve the construction environment, and ensure product quality. It is undeniable that the prefabricated box girder inner mold integral extraction device disclosed in the patent can indeed achieve the above-mentioned effects, but it still has certain shortcomings: when the inner mold moves on the demoulding platform, the concrete slag attached to the inner mold will fall on the demoulding platform, affecting the smooth movement of the inner mold; secondly, the inner mold is difficult to align when entering the demoulding platform, and it may take more time to adjust the relative position of the demoulding platform and the inner mold, which will increase the complexity of the operation and the risk of error to a certain extent, and reduce the working efficiency.

[0004] The information disclosed in this background technology section is only intended to increase the understanding of the overall background of the present invention, and should not be regarded as an admission or any form of suggestion that the information constitutes the prior art already known to those skilled in the art.

[0032] The following is a clear and complete description of the technical solution of this utility model. Obviously, the embodiments described are part of the embodiments of this utility model, not all of them. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without making any creative efforts are within the scope of protection of this utility model.

[0033] Example

[0034] See attached Figure 1-6 , the inner formwork removal platform based on the prefabricated box beam mobile pedestal production line includes:

[0035] The support frame 10 has a plurality of rubber-coated rollers 11 rotatably connected to the support frame 10 at intervals in the middle of the top of the support frame 10, and the rubber-coated rollers 11 are perpendicular to the length direction of the support frame 10; in this embodiment, a plurality of self-locking universal wheels 12 and a height adjustment member 13 are installed at the bottom of the support frame 10, wherein the height adjustment member 13 includes a threaded rod 131 extending into the bottom of the support frame 10 and threadedly engaged with it, an adjusting nut 132 welded to the threaded rod 131 near the bottom position and a base 133 rotatably connected to the bottom of the threaded rod 131; in addition, in this embodiment, protective frames 14 are symmetrically fixed on both sides of the top of the support frame 10 along its length direction, the inner side surface of the protective frame 14 has an inclined surface inclined downward, and the cross-section of the protective frame 14 is a right-angled trapezoid; secondly, horizontally arranged walking frames 15 are symmetrically fixed on both sides of the support frame 10, the top of the walking frame 15 is paved with an embossed steel plate (not marked in the accompanying drawings), and a guardrail 16 is fixed to the outer side of the top of the walking frame 15; a ladder 17 is provided on the side of the outer end of the support frame 10;

[0036] The hoist 20 is fixed to the outer end of the support frame 10;

[0037] The guide plate 30 is fixed to the inner end of the support frame 10. The guide plate 30 includes a horizontally arranged bottom plate 31 and side plates 32 symmetrically fixed to both sides of the bottom plate 31 and with outer ends inclined outwards.

[0038] During use, the adjusting nut 132 is rotated counterclockwise with the help of an external tool, and the adjusting nut 132 drives the threaded rod 131 to rotate. The top of the threaded rod 131 continues to extend into the support frame 10, and the support frame 10 is lowered. When the self-locking universal wheel 12 abuts against the ground, the adjusting nut 132 is continued to be rotated, and the base 133 is separated from the ground. The self-locking universal wheel 12 supports the support frame 10. At this time, the entire device is moved to the working area with the help of the self-locking universal wheel 12 and corresponds to the position of the inner mold 40 to be removed. Then the nut 132 is adjusted clockwise to separate the self-locking universal wheel 12 from the ground and the base 133 abuts against the ground to support the support frame 10. The adjusting nut 132 is continued to be rotated until the top surface of the rubber-coated roller 11 is flush with the ground of the inner mold 40 to be removed. This can avoid large-angle damage when pulling out the inner mold 40, and eliminate the wear problem of the inner mold 40 during the pulling and removal process.

[0039] A release agent is applied between the inner mold 40 and the concrete of the box girder 50. The wire rope of the winch 20 is bolted to the inner mold 40. When the winch 20 is in operation, the wire rope pulls the inner mold 40, thereby pulling the inner mold 40 out of the box girder 50. When the outer end of the inner mold 40 enters the support frame 10, the guide plate 30 guides it, facilitating accurate entry of the inner mold 40 into the support frame 10 and contact with the rubber-coated rollers 11. Since the rubber-coated rollers 11 are spaced apart, concrete slag attached to the inner mold 40 can fall to the ground through the gap between adjacent rubber-coated rollers 11, avoiding interference with the movement of the inner mold 40 and ensuring smooth movement of the inner mold 40. In this way, the inner mold 40 can be removed from the box girder 50 with the help of the winch 20, completing the removal operation.

[0040] In addition, the protective frames 14 on both sides of the support frame 10 have inclined surfaces corresponding to the sides of the inner mold 40. The inclined surfaces of the protective frames 14 are coated with lubricating oil, and the protective frames 14 play a guiding and protective role for the inner mold 40. Secondly, the support frame 10 is provided with a walking frame 15 on both sides. The operator enters the walking frame 15 via a ladder 17 and can perform other operations such as polishing and oiling the inner mold 40.

[0041] The foregoing descriptions of specific exemplary embodiments of the present invention are for purposes of illustration and description. These descriptions are not intended to limit the present invention to the precise forms disclosed, and it is apparent that many modifications and variations are possible in light of the foregoing teachings. The exemplary embodiments have been selected and described for the purpose of explaining the specific principles of the present invention and their practical application, thereby enabling those skilled in the art to realize and utilize a variety of exemplary embodiments of the present invention and various options and variations. The scope of the present invention is intended to be defined by the claims and their equivalents.
