Problems solved by technology

[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 single warehouses and single warehouse circulating hot air maintenance, when the kiln door of a certain warehouse is opened, the hot air in the vertical kiln leaks out, and the cold air outside the kiln replenishes into the kiln, causing the instantaneous temperature change in the kiln to exceed the specification requirements. If the maintenance of the drawer-type three-dimensional curing kiln is carried out by separate isolation of single chambers and single-chamber circulating hot air maintenance, it will bring about the problem of high equipment cost. In the prior art, a single three-dimensional cupola kiln is also used for maintenance. The device pushes the multiple molds stacked on it to rise and fall as a whole. The problem is that the kiln body is too high, the kiln body, the mold in the kiln, the concrete in the mold and the equipment are too heavy, and the foundation and structure of the kiln body are expensive. Once the mold in the kiln is lifted If the equipment or kiln roof traverse equipment fails, the production line will be completely shut down, and the equipment cost is high, the maintenance work is difficult, and a single three-dimensional cupola cannot meet various maintenance systems. Different concrete prefabricated components can be highly efficient at the same time on the same production line equipment. Production, in addition, the existing technology also adopts the form of water-sealed tank to seal the top-layer mold in the three-dimensional cupola kiln. The heat dissipation of the water-sealed tank is large, which is not conducive to saving maintenance energy. The existing technology also uses a combined mold stack in the kiln. For curing in a lifting three-dimensional curing kiln, the technical mold needs to be equipped with a mold support device for supporting the mold above the mold. The setting of the support device reduces the effective utilization of the mold area and further increases the weight of the mold. The molds are stacked in the ascending and descending channels of the mold, and the traversing mechanism is set on the top of the kiln. The molds in the ascending and descending channels of the mold must be filled to realize the operation. The lack of molds in the kiln cannot operate, and when the production is not full When it is time, it is necessary to put empty molds to fill its space, which brings troubles to production management and high production and management costs
