Problems solved by technology

However, these two solutions still require a lot of manual binding, and their automation is not high, and there is still a big gap between the industrialized construction requirements based on modern factories.

Embodiment 1

[0053] The present invention mainly comprises the following several steps to complete the production of steel mesh sheet:

[0054] (1) Stirrup fabric:

[0055] The three-dimensional mesh is formed by one plane bending and two three-dimensional bending. In order to ensure the control of the butt joint accuracy in the later construction, the reinforcement and positioning before plane bending are particularly critical.

[0056] The stirrups are loaded onto the cloth table in sequence, and the positioning grooves 8 of the multiple positioning mechanisms 4 correspond to each other in the transverse direction, so that all the stirrups constituting the mesh are evenly distributed in the positioning grooves 8 according to the set spacing. On the distributing table, the stirrups take 50mm as the interval modulus (that is, the stirrup spacing can be set to 100mm, 150mm, 200mm, etc.) to complete the plane distribution. A kind of specific structure of the positioning groove 8 of the pre...

Embodiment 2

[0072] Also includes stirrup stock before stirrup cloth:

[0073] Due to the variable cross-section design of the bridge tower, the length of each stirrup is different. In order to achieve fast and accurate cutting, the production line is equipped with a special intelligent bar shearing mechanism 2, which cooperates with a dedicated automatic conveying The roller table completes the fully automatic butt welding of the steel bars on the line, and then completes the rapid sizing and cutting on the production line according to the production needs. The characteristics of joint processing, fast welding speed and reliable quality.

[0074] After the stirrup blanking and butt welding are completed, it will be automatically transported to the stirrup waiting platform until all the stirrups required for the entire mesh are ready, and the transfer process of the stirrup adopts the stirrup stepped feeding mechanism 3 Automatically, this mechanism can realize unmanned transfer and autom...

Abstract

The invention discloses a flexible production line for a spatial three-dimensional reinforcing mesh, which comprises a stirrup cloth production line, a bending production line, a main reinforcement cloth production line, and a gantry production line. The present invention also discloses a flexible production process for the spatial three-dimensional reinforcing mesh, which includes the following steps: S1, preparing stirrups and completing plane distribution; S2, pulling the stirrups onto a bending platform; S3, horizontally moving a guide beam in the same longitudinal direction so that the stirrups are planarly bent according to a set bending angle; S4, sequentially distributing main reinforcement; S5: welding and binding to form a mesh; S6, successively performing operations from an outside three-dimensional bending mechanisms to bend the mesh twice from the two sides of the production line to its centerline to achieve three-dimensional bending forming of the mesh; and S7, after themesh is formed, lifting the mesh out of the production line. The production line and the production process of the invention can improve the industrialization, mechanization, automation, and assemblylevel of the bridge tower spatial three-dimensional reinforcing mesh construction .

Description

technical field [0001] The invention relates to the field of bridge assembly construction. More specifically, the present invention relates to a flexible production line for three-dimensional steel mesh and its production process. Background technique [0002] Concrete bridge towers are widely used in long-span cable-stayed bridges and suspension bridges. From the Xihoumen Bridge on the eastern coast to the Hong Kong-Zhuhai-Macao Bridge on Lingdingyang, from the Chishi Bridge to the Guizhou Pingtang Bridge in the western mountainous area, concrete bridge towers have been used all the time. It keeps creating its own records in terms of height, volume, shape and construction conditions. [0003] The most common method of steel bar construction for bridge pylons is the processing of individual components in the back field, and the on-site binding and forming are all manual. This is a labor-intensive operation with low technical requirements and strong adaptability to special-s...
