Abstract

The invention discloses a large-tonnage duct piece vacuum suspender which comprises a vacuum pump assembly, a vacuum chamber, an air suction solenoid valve, an air exhaust solenoid valve, a sucker hanger, a sucker, and a rubber sealing ring; the vacuum chamber has a hollow structure; the vacuum pump assembly is communicated with the vacuum chamber through a high pressure air pipe; one end of the air suction solenoid valve is communicated with the vacuum chamber, and the other end is connected with the internal space of the sucker through the high pressure air pipe; one end of the air exhaust solenoid valve is connected with the internal space of the sucker through the high pressure air pipe, and the other end is communicated with the atmosphere; the sucker is fixed at the bottom of the sucker hanger; the sucker hanger is suspended at the bottom of the vacuum chamber through a rotating shaft; an annular groove is disposed at the sucker bottom; the upper half part of the rubber sealing ring is inlaid in the annular groove at the sucker bottom. The large-tonnage duct piece vacuum suspender of the invention has great breaking tenacity; during workpiece hoisting carrying, no damage is caused to the workpiece; and the large-tonnage duct piece vacuum suspender of the invention has the advantages of reliable suction, large hoisting weight, and the like.

Description

technical field [0001] The invention relates to a vacuum sling, in particular to a large-tonnage segment vacuum sling. Background technique [0002] At present, the spreaders on the market often use hook-type spreaders and wire-cable spreaders. It is often scratched, which affects the appearance quality of the product. SUMMARY OF THE INVENTION [0003] The problem to be solved by the present invention is to overcome the deficiencies in the background technology and provide a large-tonnage segment vacuum lifter. It will not cause any damage to the workpiece, and it also has the advantages of reliable suction and large lifting weight. [0004] In order to solve the above problems, the present invention adopts the following technical solutions: [0005] A large-tonnage segment vacuum lifter of the present invention includes a hook, a vacuum pump assembly, a vacuum chamber, a suction solenoid valve, a deflation solenoid valve, a suction cup lifting lug, a suction cup, and a...
