Selection and configuration of lifting equipment:
The lifting equipment is mainly hydraulic lifting items, steel lines, hydraulic pump stations and hydraulic control systems. The principle of equipment selection is: to meet the requirements of the lifting force, the pipeline should not be too long, the structure should be compact, strong, durable, and the maintenance side should meet the needs of stroke lifting speed, safety protection and other functions! Please.
For the overall lifting of roof or grid with large projection area, multiple lifting points and large load difference, different combinations of hydraulic kilokg items with different specifications and different rated loads can be used according to the set requirements, which not only ensures the small lift difference, but also ensures the stability and safety of roof and bearing column. After the lifting point is determined, the force of each lifting point is calculated, and the selection of lifting equipment is based on various adverse conditions during the lifting process and the maximum force value of the lifting point, and the lifting equipment is reasonably combined and set according to the force size to ensure the safety of the use of a single steel grain line: for the pull-up lifting, the safety factor should be greater than 3.5. Most of the current construction requires a safety factor of about 3, that is, the theoretical design force of a single steel grain is 9 tons; For climbing lift, the safety factor should be greater than 55.
Composition and installation of hydraulic lifting system
Composed of:
Each lifting point should be set up a set of hydraulic lifting system, each set of lifting system by the work column, workbench, bearing beam, hydraulic lifting items, steel wire, special spreader, three sets of special automatic tool error, special tool clip, steel wire guide pipe, steel wire guide frame, displacement sensor, pressure transmitter, control group and multi-pump head stage hydraulic pump station system. The main components of the hydraulic lifting jack are: base, lower automatic tool anchor, extra special tool clip, lower bracket, single cylinder jack, piston internal steel line guide pipe, central automatic tool fault (piston end), displacement sensor, upper bracket, upper automatic tool fault tray, upper automatic tool fault, steel line support, steel line support. The hydraulic pump station is divided into the main pump station and the auxiliary pump station, the main pump station can be set up for "one control one lifting point", or "one control multiple lifting points". The customer's preliminary requirements for this solution are "one control twenty lifting points". The work column, workbench and bearing beam can be specially designed, manufactured and set for different situations. They are the bearing supports of the hydraulic lifting jacks of the main lifting equipment.
Synchronous lifting jacks mainly rely on hydraulic principle to achieve jacking operation and achieve synchronous effect. The hydraulic cylinder is filled with hydraulic oil, and when the hydraulic pump works, the high-pressure hydraulic oil is injected into a chamber of the hydraulic cylinder, making the pressure in the chamber rise. According to PASCAL's law, pressure is transmitted evenly through the liquid, which pushes the piston towards the other chamber, which in turn causes the ejector rod to extend. In terms of synchronization, specialized synchronization control systems play a key role. It monitors the working indicators of the jack in real time through the sensors installed in various parts of the jack, such as travel changes, pressure fluctuations, etc. Once there is a deviation between the working state of a jack and other jacks, the control system immediately adjusts the hydraulic oil supply of the jack, corrects the deviation by changing the flow rate and pressure of the hydraulic oil, and ensures that all jacks lift heavy objects simultaneously, which is particularly important in the overall lifting project of large building components.
1. Check whether the Hydraulic Strand jack is normal before use.
2. Hydraulic Strand jack should strictly comply with the provisions of the main parameters, avoid ultra-high overload, otherwise when the lifting height or lifting tonnage
When the limit is exceeded, serious oil leakage will occur at the top of the cylinder.
3. such as manual pump body oil amount is insufficient, need to add to the pump should be fully filtered N33# hydraulic oil to work
Do.
4. Please refer to the manual for Synchronous lifting electric pump.
5. The center of gravity to choose moderate, reasonable choice of jack point of impact, the bottom surface to pad flat, while taking into account the ground
Soft and hard conditions, whether to liner tough wood, placing is smooth, so as not to load down or tilt.
6. After lifting the heavy object, the heavy object should be supported firmly with the support in time, and the jack is prohibited as a support
Use. If you need to support heavy objects for a long time, choose CLL self-locking jack
7. If you need several jacks lifting at the same time, in addition to the correct placement of the jack, should use multiple shunt valve, and each
The load of the jack should be balanced, and attention should be paid to keeping the lifting speed synchronized. The possibility of subsidence due to uneven weight must also be considered
The situation is to prevent the danger of tilting the object being lifted.
