Combined three-dimensional curing kiln concrete member production line and using method thereof

Abstract

The invention discloses a combined type three-dimensional curing kiln concrete member production line. An empty mold operation area, a pouring vibration operation area and a maintenance operation areaare arranged according to an operation and circulation sequence of a precast concrete component mold in a production process. The empty mold operation area, the pouring vibration operation area and the maintenance operation area are connected through an empty mold operation area mold longitudinal conveying roller way and / or a mold transverse circulating chain conveying device which are oppositelyarranged. A plurality of off-line empty mold operation tables for empty mold operation are arranged on an outer side of one side or the outer sides of the two sides of the mold longitudinal conveyingroller way in the empty mold operation area, and a maintenance production line is provided with a plurality of three-dimensional maintenance kilns arranged in a combined mode. The invention also discloses a using method of the combined type three-dimensional curing kiln concrete member production line. The production line and the method are suitable for large-scale production.

Description

technical field [0001] The invention relates to the technical field of production of concrete prefabricated components, in particular to a combined three-dimensional curing kiln concrete component production line and its use method. Background technique [0002] At present, there are mainly two types of three-dimensional curing kilns for prefabricated concrete components: one is a three-dimensional curing kiln that uses molds to move up and down inside the curing kiln. The air is lost, but the water in the water seal tank is heated and evaporated to take away the heat, which increases the maintenance cost. The molds in the ascending and descending channels of the kiln are stacked up and down. Due to the large number of stacked molds in one channel, they are stacked together. The weight of the mold is heavy. Due to the diversity of concrete component products, the weight distribution of the concrete component and the mold cavity structure on the mold chassis is inconsistent. ...

Problems solved by technology

[0002] At present, there are mainly two types of three-dimensional curing kilns for prefabricated concrete components: one is a three-dimensional curing kiln that uses molds to move up and down inside the curing kiln. The air is lost, but the water in the water seal tank is heated and evaporated to take away the heat, which increases the maintenance cost. The molds in the ascending and descending channels of the kiln are stacked up and down. Due to the large number of stacked molds in one channel, they are stacked together. The weight of the mold is heavy. Due to the diversity of concrete component products, the weight distribution of the concrete component and the mold cavity structure on the mold chassis is inconsistent. Multiple hydraulic lifting cylinders are used to lift the heavy mold stacked above from the bottom mold. , the actions of multiple hydraulic lifting cylinders cannot be precisely synchronized. The bottom mold bears the total weight of the mold and concrete components above it, resulting in an additional increase in the structural strength of the mold for stacking weight. The cost of equipment and molds is high, energy consumption is large, and the mold is easy. Deformation, in order to realize mold stacking, a supporting device for supporting the mold above the mold needs to be installed on the mold. The setting of the supporting device reduces the effective utilization rate of the mold area and further increases the weight of the mold. In the process of rising and falling, huge side pressure is generated on the side wall guide due to the bias, and the wear of the mold and equipment is inevitable, which increases the maintenance workload of the mold and equipment

In order to resist the increase of the mold structure and the increase in self-weight, the input power of the lifting mechanism needs to be increased, and the equipment cost and operating cost will increase. Slow, long production takt time, low production efficiency. In addition, because the molds are stacked in the mold ascending and descending channels, and the traversing mechanism is set on the kiln roof, the molds in the mold ascending channel and mold descending channel must be filled. To achieve operation, the lack of molds in the kiln cannot operate. When the production is not full, empty molds need to be put in to fill the space, which brings troubles to production management and high production and management costs; the other is to use maintenance during the maintenance process. In the three-dimensional curing kiln where the mold inside the kiln does not move, the multi-cell curing kiln body uses a palletizer in common. Since the palletizer needs to receive the mold from the bottom of the curing kiln, move the mold laterally, lift the mold, Multiple kiln entry actions such as sending the mold into the curing kiln compartment, or multiple kiln exit actions such as taking out the mold from the curing kiln compartment, laterally moving the mold, lowering the mold, and sending the mold away from the curing kiln, etc. The operation cycle time of the palletizer is long, and it cannot meet the needs of high-speed production with a very large number of molds and a very short operation cycle time. The structure of the palletizer is complex, the cost is high, and it cannot be supported by other equipment without stopping production after a failure

[0003] The empty mold operation of the above two production line molds is completed online during the circulation of the empty mold operation area. When the same production line needs to produce a variety of products with inconsistent operation time of the empty mold operation at the same time, the running direction of the mold encounters When the product mold with long empty mold operation processing time in the front has not completed the empty mold operation operation, the mold located behind it with a shorter empty mold operation operation time has completed its related empty mold operation operations, but still cannot surpass the front mold circulation. To the next operation station, it is necessary to wait for the mold in front to complete its related empty mold operation before following it to the next operation station, resulting in waste of production time and limited production capacity of the production line
