Problems solved by technology

However, for non-production line assembly occasions, this type of pneumatic balancer cannot realize the full-range suspension and lifting of heavy objects of different weights, and the operator needs to provide a large operating force to make the heavy objects rise or fall, which greatly reduces the pneumatic balance. The scope of suspension lifting of the device reduces the availability of production capacity

Abstract

The invention discloses a suspension pneumatic lifting device and a suspension pneumatic lifting method. Specifically, the suspension pneumatic lifting device comprises a gas source, a power access circuit, a reversing valve, an electropneumatic proportional valve, a two-position three-way electromagnetic valve, a pneumatic lifting apparatus, a controller and a tension sensor. The reversing valve and the electropneumatic proportional valve are respectively connected to the gas source and the two-position three-way electromagnetic valve, the two-position three-way electromagnetic valve is in connection with the pneumatic lifting apparatus, and the power access circuit has a control switch for controlling power supply to the electropneumatic proportional valve, the two-position three-way electromagnetic valve and the controller. The controller compares the test data value with a set value, if the test data value is smaller than the set value, the electropneumatic proportional valve is controlled for communicating an air inlet with the two-position three-way electromagnetic valve, if the test data value is greater than the set value, the electropneumatic proportional valve is controlled for communicating an air outlet with the two-position three-way electromagnetic valve. The suspension pneumatic lifting device and the suspension pneumatic lifting method provided by the invention can realize rapid raising and descending of a hoisted object with any weight.

Description

technical field [0001] The invention relates to the technical field of lifting equipment, in particular to a suspension pneumatic lifting device and a suspension pneumatic lifting method. Background technique [0002] At present, domestic hoisting equipment mainly includes pneumatic hoist, electric hoist, and pneumatic balance crane. In the mechanical production and assembly industry, especially where high positioning accuracy is required, air hoists and electric hoists generally cannot meet the requirements. At present, the domestic pneumatic control technology is developing very rapidly, and the application of pneumatic balance cranes is becoming more and more extensive. It realizes the suspension function of constant weight materials near the balance point, and provides convenient conditions for my country's assembly industry. However, the pneumatic balance cranes currently on the market use a separate control method for no-load balance and heavy-load balance in terms of...
