Base includes scaffold, scaffold fills air pressure supporting arrangement, four the pneumatic cylinder collaborative works of air pressure supporting arrangement, fills mobile device bottom scaffold;During duty, the expansion link of pneumatic cylinder is propped up, and on the ground, mobile device does not contacts with ground, and pneumatic cylinder undertakes whole load in supporting;When needs are mobile, the expansion link of pneumatic cylinder is retracted, and mobile device contacts with ground, and pneumatic cylinder is not directly contacted with ground, it is achieved the movement of the little scope in indoor of whole boom hoisting.
Transformer crane device of the present invention uses double shear V shape gantry structure, maximum lift height up to 8 meters, maximum weight lifting is up to 12 tons.This device is designed to combined modular structural shape, and lifting uses air pressure actuation techniques.Each assembly of component devices (such as scissors rod lift assemblies, crossbeam) is all modular organization, can assemble according to actual needs, it is achieved differing heights, the lifting of amplitude, it is simple to carry out Mission Operations in the interior space.It addition, this boom hoisting is equipped with different suspender, such as steel cable, woven belt etc., it is achieved the lifting requirement of different objects.
Accompanying drawing explanation
The invention will be further described with embodiment below in conjunction with the accompanying drawings.
Fig. 1 is the structural representation of one embodiment of the invention.
Fig. 2 is the operation principle schematic diagram of control system.
Fig. 3 is scissor cellular construction schematic diagram.
Detailed description of the invention
A kind of high-power transformer bell jar indoor vertical lifting device on the spot, including left and right base 1,2, the left and right pair of scissor lifting device 3,4 being promoted lifting by left and right pneumatic cylinder it is respectively mounted on left and right base, the top dress crossbeam 5 of left and right pair of scissor lifting device, crossbeam hangs the suspension hook of bell jar equipped with lifting transformer;The displacement transducer 6 that left and right pair of scissor lifting device adjustable height of dress detection is the most consistent on crossbeam;Displacement transducer is connected with control module 7, and the sync control device 13 that the main frame 8 of control module is synchronized with the movement with the left and right pneumatic cylinder 11,12 of control is connected;
During work, the main frame of control system sending instruction, left and right pneumatic cylinder works, and left and right pneumatic cylinder promotes left and right pair of scissor lifting device, drives crossbeam to rise, and crossbeam hangs bell jar by hook transformer;The left and right pair of scissor lifting device adjustable height that employing displacement transducer carries out detecting crossbeam both sides is the most consistent, and Real-time Feedback, if there being error, being adjusted by control system, reaching the synchronization job of both sides lift height, it is ensured that the balance of elevated object in lifting process.
Base includes scaffold, scaffold fills air pressure supporting arrangement 9, four the pneumatic cylinder collaborative works of air pressure supporting arrangement, fills mobile device 10 bottom scaffold;During duty, the expansion link of pneumatic cylinder is propped up, and on the ground, mobile device does not contacts with ground, and pneumatic cylinder undertakes whole load in supporting;When needs are mobile, the expansion link of pneumatic cylinder is retracted, and mobile device contacts with ground, and pneumatic cylinder is not directly contacted with ground, it is achieved the movement of the little scope in indoor of whole boom hoisting.Realized co-operating air pressure module 14 by the main frame 8 of control system to control, thus complete four, bottom and support the control of pneumatic cylinder.
Double scissor lifting devices, it is contemplated that in indoor use, need manpower to move into and take out of, and this device has some scissors rods that can single move to combine.
