  1. 钢锁式液压顶升 Steel lock hydraulic jacking

钢索式液压提升装置是以液压油为动力,推动液压缸活塞往复运动,使与活塞上端连接的上卡紧机构和与缸体下部连接的下卡紧机构之间进行载荷转换,从而实现提升(或下降)重物的一种新型、特殊的起吊设备。因为选用结构形式为1×7-Φ15.2的高强度预应力钢绞线作为卡紧机构内的承力件,故定名为"钢索式液压提升装置",以汉语拼音字头"GYT-**"表示。

一套设备由结构相同的四台液压千斤顶、二台液压泵站和一个电器控制柜等主要部套件组成。组合形式为一台液压泵站驱动二台千斤顶,相互之间用高压胶管及信号电缆连接,组成一个单元,共二个单元。二个单元通过控制电缆与电器控制柜连接,有电器控制柜进行集中控制,既可二组联动,也可以单组运行。系统基本配置为四个千斤顶单元,可通过扩展实现八、十二个单元及多单元同步集群控制。

到目前为止,该设备已完成国内大型建筑和电力建设项目500余项(吊重10-2000t,吊高10-270m)。实践证明,钢索式液压提升装置广泛适用于大型设备的起吊、安装和张紧。

The Steel lock hydraulic jacking device uses hydraulic oil as the power to push the piston of the hydraulic cylinder to replace movement, so that the upper clamping mechanism connected to the upper end of the piston and the lower clamping mechanism connected to the lower part of the cylinder are gradually converted to achieve lifting ( (Or drop) a new type of special lifting equipment for heavy objects. Because the alternative structure is 1×7-Φ15.2 high-strength pre-stressed steel strands as the internal load-bearing parts of the clamping mechanism, it is named ". Steel cable hydraulic lifting device" with the initials of Chinese pinyin" GYT-** type" means.

A set of equipment consists of four hydraulic jacks with the same structure, two hydraulic pump stations and an electrical control cabinet. The combination form is that one hydraulic pump station drives two jacks, which are connected with each other by high-pressure hoses and signal cables to form a unit, with a total of two units. The two units are connected to the electrical control cabinet through the control cable, and the electrical control cabinet is centrally controlled, which can be linked by two groups or run in a single group. The basic configuration of the system is four jack units, which can be expanded to realize synchronous conversion control of eight or twelve units and multiple units.

Facts have proved that the steel cable hydraulic lifting device is widely used for the lifting of large-scale equipment. When installed, the equipment has completed more than 500 large-scale construction and power construction projects (lifting weight 10-2000t, lifting height 10-270m). And tensioned.
