Three-dimensional production system of prefabricated components

Abstract

The invention relates to the field of production of prefabricated components, in particular to a three-dimensional production system of the prefabricated components. The system comprises a prefabricated component production area on the upper layer, a maintenance area on the lower layer and a wheel type mold table; the prefabricated component production area includes a component prefabrication operation area, a component demolding operation area and an edge mold cleaning operation area; the maintenance area is provided with a linear maintenance kiln; the components are borne on a production line in the prefabricated component production area through the wheel type mold table, and move in the linear maintenance kiln in the maintenance area; a mold table ferry transverse moving station is arranged in the prefabricated component production area; a mold table lifting transverse moving device is arranged on the mold table ferry transverse moving station; a special production line and a production secondary line are arranged in the component prefabrication operation area; and the special production line drives the wheel type mold table to transversely move through the mold table lifting transverse moving device so as to connect with the production secondary line in parallel. The system comprehensively improves a prefabricated component production system, can realize multiple production modes, is more flexible in production, and greatly improves the production efficiency.

Description

technical field [0001] The invention relates to the field of prefabricated component production, in particular to a three-dimensional prefabricated component production system. Background technique [0002] Prefabricated housing is a green and environmentally friendly new housing construction method. The country and various provinces and cities attach great importance to it and have issued a number of supporting policies. The development of prefabricated buildings is bound to be inseparable from prefabricated concrete (PC) components, and the production of prefabricated components is inseparable from advanced production methods and equipment. After more than 10 years of development, there are currently many domestic companies that can manufacture a complete set of precast concrete component production lines (referred to as "PC lines"), but the general form is the same. This production mode has the disadvantages of large area, large investment, complex equipment structure, D...

AI Technical Summary

Problems solved by technology

[0004] (1) The amount of supporting wheels is large. A complete PC integrated line in the original production system needs to install 4 to 6 columns and 400 to 500 supporting wheels. It is time-consuming and laborious to install so many supporting wheels

[0005] (2) The installation requirements of the support wheels are high. During installation, each row of support wheels must be on a straight line without deviation, and the height of all support wheels and the support wheels on the auxiliary equipment must be completely consistent. In actual work, it is necessary to It takes a lot of manual and repeated adjustments to complete. If the support wheel is not installed properly, it is easy to cause the mold table to walk poorly on the support wheel, or even the mold table to slip, and it is necessary to regularly check the support wheel

[0006] (3) The friction position of the rubber driving wheel is on the channel steel on both sides of the mold table, and it is easy to have inconsistent power, which will cause the mold table to drift and slip off the support wheel

In addition, the rubber driving wheels will wear to different degrees in actual use. When the rubber wheels on both sides wear inconsistently, the driving force of the rubber wheels will be inconsistent, causing the mold table to slip off the supporting wheels

[0007] (4) The mold table is too high from the ground, which affects workers working on the mold table. Generally, the height of the support wheel is about 450mm, and the thickness of the mold table is 300mm. In this way, the height of the upper surface of the mold table from the ground is about 750mm. The upper and lower mold tables cause great difficulties

[0009] (1) There are a large number of cold bridges in the curing kiln, the heat loss rate is as high as 30%, and the steam consumption is very large, resulting in energy waste and high component costs

[0010] (2) The curing kiln and the production line are on the same plane of the workshop, which not only occupies the workshop area, but also restricts the layout of the workshop process, making it difficult to increase production capacity

[0011] (3) The matching equipment palletizer has complex structure, high installation requirements, difficult operation, poor stability, low efficiency, high noise and high energy consumption

[0012] (4) Since large components cannot enter the curing kiln, it is necessary to build a workshop of 4,000 to 6,000 square meters as a fixed formwork workshop. Long cycle, low efficiency, high cost

The above concrete feeding and distributing methods are obviously difficult to meet the requirements of production automation

[0017] In addition, according to the current situation of unbalanced economic development in various regions of my country, as well as research on the development of the housing assembly industry, many third- and fourth-tier cities do not yet have the ability to build houses in a fully-assembled manner in the process of developing prefabricated housing. Generally, it starts with the use of prefabricated truss steel bars to laminate the floor, and gradually increases the amount of prefabricated components used to increase the assembly rate. However, the prefabricated component production system in the prior art can only be put into production in one step, and the investment is large. If the prefabricated components The production line can be upgraded in a timely manner according to actual needs, which will undoubtedly reduce the initial investment in plant construction, reduce operating risks, and make rational use of resources
