Shield segment vibrating and pouring integrated complete tool

Abstract

The invention discloses a shield segment vibrating and pouring integrated complete tool. The tool comprises a shield segment bottom die, wherein the shield segment bottom die is arranged on a trolley moving along parallel rails. The tool further comprises a positioning device, a cover plate lifting system, a cover plate clamping system and a cover plate, wherein the cover plate and the shield segment bottom die are combined to form a segment die assembly used for pouring. Intelligent automatic alignment of segment dies is achieved, original manual auxiliary alignment is omitted, and errors caused by manual auxiliary alignment and the risk of mechanical damage caused in the manual alignment process are avoided. According to the tool, an original fixed cover plate on each segment die is omitted, a standardized general cover plate with a clamping device is designed, the general cover plate is mechanically opened and closed in a vibration sound insulation room of a pouring vibration station, the labor intensity and the safety risk of operators are reduced, meanwhile, the self weight of the die is reduced by adopting the general cover plate, the die purchase cost is saved, and the production efficiency is improved.

Description

technical field [0001] The invention belongs to the technical field of construction machinery design, and relates to a tooling for pouring and vibrating stations of a segment assembly line, in particular to a pouring and vibrating integrated tooling set based on the lightweight design of segment molds. Background technique [0002] The shield tunneling method is a fully mechanized construction method in the underground excavation method, which has been widely promoted and widely used. Prefabricated concrete lining segments are the main prefabricated components of the shield tunnel lining structure. Except for emergency production, almost all of them adopt the assembly line method for production organization. With the continuous development of construction industrialization, the concepts of factory production of components and parts, intelligent manufacturing and smart factories are gradually implemented. The current general-purpose segment molds and equipment tooling are gra...

AI Technical Summary

Problems solved by technology

[0004] 1) The self-weight of the segment mold cover plate is relatively large. At present, the opening and closing operations of the segment mold are all done manually, and because the segment mold cover plate lacks ergonomic design, this operation is labor-intensive. When the cover plate falls, it will touch the mold body The impact noise is loud, which endangers the occupational health of workers;

[0005] 2) The frequent opening and closing of the segment mold cover plate will greatly increase the risk and probability of mechanical injury caused by this operation;

[0006] 3) Since each segment mold is equipped with a corresponding mold cover plate, the overall weight of the segment mold increases, the amount of steel used for manufacturing increases, and the manufacturing cost increases

[0007] 4) Due to the frequent opening and closing of the segment mold cover plate, the flow rate of the segment assembly line is reduced, the production efficiency is reduced, the production capacity of the segment assembly line is limited, and the economic benefits of the project are reduced

[0008] (2) At present, the pouring and vibrating process of the conventional segment assembly line has problems such as low overall intelligence, high labor intensity, and high safety risks. The details are as follows:

[0009] 1) Before the segment is poured and formed, the segment mold needs to be manually positioned to align with the position of the concrete discharge port. This operation is labor-intensive, low in intelligence, and poor in alignment accuracy, which is likely to cause mechanical damage during the operation;

[0010] 2) It takes a long time to manually position the segment mold, which leads to the reduction of the flow rate of the segment assembly line, the decrease of production efficiency, the limitation of the production capacity of the segment assembly line, and the decline of the economic benefit of the project;

[0011] 3) Low alignment accuracy leads to unavoidable spillage and waste during the concrete blanking process, resulting in increased construction costs due to waste of raw materials and cleaning of spilled concrete
