Multipurpose precast concrete component production line and application method thereof

Abstract

The invention discloses a multipurpose precast concrete component production line. The production line comprises a special-shaped component operation area, a plate component operation area and a concrete stirring operation area and further comprises a plurality of concrete mixing main machines, a plurality of online empty mold operation mold conveying channels, a plurality of off-line empty mold operation stations, a plurality of mold transverse moving devices using circulating chains, a plurality of combined primary and secondary mold carriers, a plurality of secondary overlapping devices, aplurality of pouring points, a concrete conveying elevated track arranged from a concrete stirring operation area to the pouring points, and a plurality of self-propelled concrete conveying elevated hoppers. The invention further discloses a using method of the multipurpose precast concrete component production line. The production line is advantaged in that the production line is reasonable and ingenious in structural design, suitable for simultaneous online production of precast concrete components needing different curing systems, and suitable for simultaneous online production of the precast concrete components needing different empty mold operation time.

Description

technical field [0001] The invention relates to a concrete prefabricated component production line, in particular to a multi-purpose concrete prefabricated component production line and a use method thereof. Background technique [0002] The existing concrete prefabricated component production lines mostly operate through online empty mold operation, concrete pouring vibration at one pouring point or two pouring points, tunnel kiln or drawer type three-dimensional curing kiln with in-situ entry and exit for curing, and component mold exiting. demoulding after the kiln to realize the production of concrete prefabricated components, among which, for products that need to implement a variety of different curing systems, the existing technology cannot be compatible with the production at the same time with high efficiency, and the empty mold operation of the prior art is usually performed along the mold. It is completed in the process of running on the vertical circulation chann...

[0002] The existing concrete prefabricated component production lines mostly operate through online empty mold operation, concrete pouring vibration at one pouring point or two pouring points, tunnel kiln or drawer type three-dimensional curing kiln with in-situ entry and exit for curing, and component mold exiting. demoulding after the kiln to realize the production of concrete prefabricated components, among which, for products that need to implement a variety of different curing systems, the existing technology cannot be compatible with the production at the same time with high efficiency, and the empty mold operation of the prior art is usually performed along the mold. It is completed in the process of running on the vertical circulation channel, and the efficiency is very low when dealing with the simultaneous production of multiple products with large differences in the operation time of empty molds. In addition, the equipment that uses the drawer-type three-dimensional curing kiln that enters and exits in situ has low operating efficiency. Furthermore, the existing technology can accommodate a small number of molds on a production line, and the tact time of equipment circulation is long. However, in the prior art, the mold needs to be transferred horizontally from one longitudinal mold conveying roller channel to another longitudinal mold conveying roller The reciprocating mold horizontal transfer vehicle is used in the channel, and the reciprocating mold horizontal transfer vehicle needs to return empty after transporting a piece of mold for lateral movement. Or use a large palletizer for the drawer-type three-dimensional curing kiln that enters and exits the two groups in situ to lift the mold and enter and exit the kiln body. The in-and-out operation has a great impact on the production capacity of the production line. In the process of tunnel curing kiln curing, the temperature change curve in the kiln cannot be accurately and gradually changed as the mold moves in the tunnel kiln, and it is difficult to meet the temperature change curve of concrete heating and curing specified in the specification. Moreover, once the kiln door of the tunnel maintenance kiln is opened, the hot air in the tunnel kiln leaks out, and the cold air outside the kiln supplements the kiln, causing the instantaneous temperature change in the kiln to exceed the specification requirements. Separate isolation of sing...
