In addition, the terms "first", "second", etc. are only used for descriptive purposes, and cannot be understood as indicating or implying relative importance or implicitly indicating the number of technical features indicated. Thus, features defined as "first", "second", etc. may explicitly or implicitly include one or more of the features. In the description of the present invention, unless otherwise specified, "multiple" means two or more.

For ordinary technicians in this field, the specific meanings of the above terms in the invention can be understood according to specific circumstances.

[0034] The present invention will be described in detail below with reference to the accompanying drawings and in combination with embodiments.

[0035] A component construction method of a cantilever beam making machine, such as Figures 1 to 9 As shown, the specific steps include:

[0036] S1. Tie the box girder reinforcement in the factory and transport it directly to the site as a finished product;

[0037] S2, lifting the box girder reinforcement;

[0038] S3, lower the box girder reinforcement onto the bridge deck's transport trolley;

[0039] S4, transport the box girder reinforcement to the place;

[0040] S5. Lower the box girder reinforcement to the pouring position;

[0041] S6. Pour and complete the construction.

[0042] After adopting this method, the construction efficiency of the cantilever beam-making machine will be greatly improved. The componentized construction method of the cantilever beam-making machine will componentize the box girder steel bars. After the prepayment in the factory, they are directly lifted into place by the lifting station and the overhead crane at the construction site, and then transported by the plate transport trolley. The componentized box girder steel bars are sent to the designated position by the bridge crane and then poured, which greatly saves construction time, does not require manual processing, and reduces safety hazards during construction. Compared with the previous method, this method has a shorter construction period, lower costs, and higher work efficiency, and has extremely high promotion value and social benefits.

[0043] In step S2, the box girder reinforcement is lifted by the lifting station, such as Figures 1 to 5 The lifting station includes a bottom frame, a top frame and a plurality of vertical support frames therebetween, and an oblique support frame is provided between the protruding part of the top frame and the bottom frame, and reinforcing rods are provided between the oblique support frame and the top frame, the bottom frame and the vertical support frames; the bottom frame is installed on the top of the cantilever beam making machine.

[0044] In step S3, the box girder steel bars are lowered to the bridge deck by a crane. Preferably, the crane is arranged at the upper end of the lifting station. Two sets of cranes are arranged on the lifting station.

[0045] In step S4, the box girder reinforcement is transported to the site by means of a transport trolley and a bridge crane.

[0046] In step S5, the box girder reinforcement is lowered to the pouring position by using a bridge crane. Preferably, the bridge crane is arranged at the upper end of the lifting station.

[0047] The method of the present invention is mainly aimed at the construction of a cantilever beam-making machine. In order to omit the construction step of tying steel bars on site, componentized construction is carried out. The box girder steel bars are tied in a factory and directly transported to the site as finished products. The box girder steel bars are lifted onto a plate transport trolley on the bridge deck by an overhead crane at a lifting station, and then lowered to a casting position by the plate transport trolley and a bridge deck crane. Finally, the casting completes the construction.

[0048] This construction method can be applied to the construction of high-altitude bridges, where cantilever beam-making machines are used. The box girder reinforcement is componentized and processed in the factory. After processing, it is directly transported to the site and then hoisted into place. This method shortens the construction time and improves construction efficiency to a certain extent. While ensuring the strength of the steel structure, componentized construction can further improve work efficiency and save time and labor costs.

[0049] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
