Construction of Lifting and Positioning of Stone lifter

Vacuum stone lifter assembly includes hoisting positioning, epoxy adhesive and tension prestressing. Generally, a segment assembly takes about 1 to 1.5 days. In addition, in the cantilever suspension, the cantilever assembly construction can be carried out synchronously with the construction of the lower structure of the bridge, which reduces the shrinkage and creep of the concrete in the beam section and is beneficial to the alignment of the main girder in the later  stage of completion of the bridge. It is composed of vacuum device and soft plastic or bowl-shaped rubber lifter head, which can be divided into power and non-power. Power vacuum stone lifter obtains vacuum by vacuum pump. It has high suction but noise. Cables or air hoses are required.           
 Non-power vacuum lifter is also called self-priming vacuum lifter. When the suction cup is lifted, the piston rod is driven by the hook to obtain vacuum. No power  source is required. It has the advantages of simple structure and no noise. There is a short circuit between the wires connected to the electromagnetic  suction cup by the electric control box, especially in the place connected to the suction cup. With the increase of the use time and frequency, the place is easy to be damaged and cause short circuit fault. Please go to check whether the coil is broken, whether there is a problem with the wire, whether there is a problem with the electronics and plugs, etc.           
 Vacuum stone suction cup relies on toughness to extrude air and use atmospheric pressure to press it on the glass after aging suction cup seal uneven leakage can not continue to use do not want to change water as a sealing material can  also be installed when tightening as much as possible to press out air if it is no longer possible to suggest replacement in order to avoid accidents.           
 Usually, if the number of vacuum lifters is not many and the diameter of vacuum lifters is not very large, it is economical to use jet vacuum attacker to produce vacuum. Since the spray vacuum generator itself needs compressed air, it does not need to install other vacuum pipes.           
 The most common method of vacuum seizure for vacuum components is jet vacuum seizure. The method of vacuum seizure should select vacuum seizure or vacuum pump according to the diameter and quantity of vacuum lifter. After the determination of the method of vacuum seizure, the following essential components are also required for the construction of vacuum lifter machinery and equipment. At present, the utilization rate of stone vacuum lifter is very high, especially in the stone processing industry. After many improvements and changes, the stone vacuum chuck has been very humanized, and has the advantages of simple operation and high efficiency.           
 With the development of science and technology, vacuum stone vacuum lifter and rodless cylinder are indispensable vacuum pneumatic parts in the development trend of automation equipment. In the robotic equipment, vacuum lifter  completely replaces manual, does not need manual handling, so that the production capacity of mechanical equipment is faster, rodless cylinder in screen printing, flying knife and other automation industries are also indispensable pneumatic accessories. In addition, in actual production, if the  stone vacuum chuck is required to be oil-resistant, the use of polyurethane, nitrile butadiene rubber or polymer containing vinyl group can be considered to make chucks.
