Synchronous sliding and lifting control method for large integrated grouped-warehouse-sliding-mode engineering

Abstract

The invention relates to a synchronous sliding and lifting control method for large integrated multiple-warehouse-sliding-mode engineering. The method includes integrated grouped warehouses which are composed of multiple silos. A plurality of adjacent silos form a set and the integrated grouped warehouses are divided into multiple groups of warehouse sliding-mode mechanisms. Each group of warehouse sliding-mode mechanisms are respectively controlled by a hydraulic control mainframe. All the hydraulic control mainframes work synchronously and are lifted at the same time. The integrated grouped warehouses are divided into multiple groups of warehouse sliding-mode mechanisms as the silos form one group. Each warehouse sliding-mode mechanism is provided with the corresponding hydraulic control mainframe and the warehouse sliding-mode mechanisms are controlled by multiple hydraulic control mainframes at the same time to achieve synchronous lifting of the silos. Compared with a control method of a single hydraulic control mainframe, loads are balanced and the lifting harmony and instantaneous synchronism are boosted. In addition, operation is convenient and cost is saved. The synchronous sliding and lifting control method for the large integrated multiple-warehouse-sliding-mode engineering can be applied to sliding-mode construction of large integrated grouped warehouses.

Description

technical field [0001] The invention relates to the sliding form construction of group warehouses, in particular to a synchronous sliding control method for the sliding form engineering of large connected group warehouses. Background technique [0002] Large-scale conjoined silos are composed of many concrete silos (usually round silos) connected to each other. Their silo walls are tangentially occluded, and the connected parts share the same silo wall. Slipform construction is generally used in this kind of project, and all silos are required to slide up at the same time during slipform construction (that is, vertical construction joints are not allowed on the silo walls). The control method of its synchronous sliding construction generally installs stoppers on the support rods. The height of each limit is the height of each slide (generally within 20cm). Slide up, and finally make all jacks reach the same elevation (all stoppers are at the same elevation) in each slide. ...

Problems solved by technology

[0003] The conventional method is to configure a hydraulic control host for each silo to control thousands of jacks to work at the same time. The instantaneous synchronous sliding of the formwork device within a sliding height (that is, the jacking speed of each jack is the same), which may cause damage to the formwork device at the tangential occlusal part between the silo walls, and even the same silo. The formwork device between the adjacent jacks may also be damaged, which is not conducive to the quality control of the sliding form engineering, and will lead to quality and safety accidents in serious cases

Moreover, only one hydraulic control host is used to control the sliding of all silos, and the parameters of the host are too large, the customization price is high, and the weight is large, resulting in uneven load, which is not conducive to synchronous sliding in terms of operability.
