Problems solved by technology

[0003] The technical problems to be solved by the present invention are: 1. The lifting balance degree of the existing lifting system is low; 2. The existing lifting system has no good method to eliminate the stress brought by the steel strand to the components; 3. Due to the distribution of the lifting point distance Larger, the main control personnel are far away from each lifting point, cannot timely understand each site, and are in a passive command state

Embodiment 1

[0061] A manually controlled central cluster program logic controls the hydraulic lift system. Such as figure 1 Shown: The system includes a load-bearing system composed of steel strands connecting jacks and components, a power system composed of multiple pump stations with rated flow according to the number of jacks, a control system composed of manual control and automatic control devices, connected by solenoid valves The control system and the power system; the jack and the power system are connected by a hydraulic oil circuit, and 1 to 4 rated flow pump stations are used in the power system to supply oil to the master cylinder of the jack.

[0062] The control system is a manual control system composed of a manual operation switch group, a computer network composed of n programmable controller PC groups, relays KD1~KDi, n K1~K9, KB1~KBj; the manual operation switch group Each group of switches is respectively connected to the digital input terminal of the programmable con...

Embodiment 2

[0071] The central cluster program logic control hydraulic lifting system with "manual adjustment steel strand stress combination system", the basic structure of the control system is the same as the first embodiment, the difference is: the system also includes "detected by the laser instrument and "Manual adjustment steel strand stress combination system" composed of manual control operation device, the combination system is composed of laser rangefinder, programmable controller, solenoid valve, jack, steel strand, the RS232 communication port of laser rangefinder through The photoelectric isolation remote transmitter is connected with the RS232 communication port of the computer, and forms a measurement connection with the component through the laser ranging beam, and the programmable controller starts the RS232 communication port and the laser instrument for data exchange according to the RS232 communication protocol; the laser distance measuring instrument The emitted dista...

Embodiment 3

[0073] A central cluster program logic control hydraulic lifting system including manual control, automatic control and adjustment control, the basic structure of the system is the same as that of Embodiment 1 or Embodiment 2, also as figure 1 Shown: The system includes load-bearing system, power system and control system.

[0074] The difference is that the control system also includes a computer network composed of automatic operation switches, travel switch groups, n programmable controller PCs, relays KD1~KDi, KB1~KBj, n K1, n Kz2 , n Kz3, n K4 ~ K9 composed of automatic control system, the specific connection method is: connected to the digital input of programmable controller PC1 by switches S01, S04, S05, S06, S08, S09, S10, S119, SS1 terminal; the travel switches SQ11~SQ1i, SQ21~SQ2i, SQ31~SQ3i, SQ41~SQ4i, SQA1~SQAi, SQB1~SQBi are connected to the digital input terminal of the programmable controller PC, n K1, n Kz2, n Kz3 are respectively connected to the digital out...

Abstract

The concentrative controlling hydraulic raising system includes bearing system, power system and control system. The manual and automatic control are realized by means of program logics, and the oilpath control is performed with switch amount controlling elements. The power system has 1-4 pump stations with rated flow rate to supply oil to main cylinders of the jacks. The control system also includes a manually regulated twisted steel cable stress combining system comprising laser instrument and manual controller, and the working jacks, pumping station and laser instrument are always controlled by PC1 concentratively. The system may have some monitoring system. Using the raising system in construction can control the displacement of the members and the stress the twisted steel cableapplies to the member and has simple and convenient operation.

Description

1. Technical field: [0001] The invention relates to a lifting device and a construction method, in particular to a hydraulic lifting system and a lifting construction method thereof. 2. Background technology: [0002] The existing logic control hydraulic lifting system has simple structure, convenient installation and debugging, and has good application effect, but its lifting balance is low, and there is no good way to eliminate the stress brought by the steel strand to the components, so it cannot be well It is applied to the lifting system. At the same time, there is a common phenomenon in the current system. Due to the large distribution of lifting points, the main control personnel are far away from each lifting point, unable to understand each site in time, and are in a passive command state. 3. Contents of the invention: [0003] The technical problems to be solved by the present invention are: 1. The lifting balance degree of the existing lifting system is low; 2. ...
