Assembly-line automatic manufacturing technology for pre-stressed concrete track board unit by pre-tensioning method

Abstract

The invention provides an assembly-line automatic manufacturing technology for a pre-stressed concrete track board unit by a pre-tensioning method. Traction equipment drives a model to flow on a track according to a time beat, wherein the time beat is working time of each station; the model bears tensioning stress, and all the stations are lined up on an assembly line and work together at the same time; and the quality and the working progress of each station are controlled by a sensor, and each station is commanded by a central control system, so that the operation of the whole system is controlled. Compared with a matrix production method, the assembly-line automatic manufacturing technology has the advantages that temporary components such as a tensile pedestal are eliminated, the model turnover rate is increased by 50 percent, the area of a factory is reduced by 30 percent or above, and the number of workers is reduced by 50 percent or above. The production process fulfills the aims of full-automatic control, informationalized transmission of key data, remote monitoring, and relocation and quick installation of all sets of equipment according to engineering requirements.

Description

technical field [0001] The invention relates to a manufacturing method of a track plate product in a high-speed railway track structure. An automatic manufacturing technology for a pretensioned two-way prestressed reinforced concrete track slab assembly line assembly line, in particular relates to the conversion of traditional pretensioned manufacturing technology to automated and informationized manufacturing technology. Background technique [0002] At present, the known high-speed railway track slabs have two methods: pre-tensioned structure and post-tensioned structure. Therefore, there are two manufacturing methods. The common feature of these two manufacturing methods is the fixed platform method. [0003] The so-called fixed-position method mode refers to the mode in which the model does not move, and other operating procedures cooperate with the model to operate in turn. For example, the traditional pre-tensioning manufacturing process first designs and builds a loa...

Problems solved by technology

The manufacturing process of the fixed station mode is characterized by man-machine cooperation, low degree of automation, large number of workers, high labor intensity, production cycle of 20h-22h, low efficiency, large production site occupied by the tension pit, and the product After the production is completed, the tension pit cannot be relocated, resulting in waste; the product quality is limited by the process conditions, and the fluctuation is relatively large. The supervision depends on spot checks, and there are many loopholes
