Abstract

The invention discloses a hoisting apparatus for indoor transformer gas-insulated switchgears with various grades. A left double-fork lifting device lifted by the pushing of a left hydraulic cylinder is installed on a left pedestal. A right double-fork lifting device lifted by the pushing of a right hydraulic cylinder is installed on a right pedestal. A crossbeam is installed on the tops of the left double-fork lifting device and the right double-fork lifting device and is provided with a hook for lifting a transformer belljar. A displacement sensor is installed on the crossbeam, is used for detecting whether the lifted height of the left double-fork lifting device is consistent with that of the right double-fork lifting device, and is connected with a control system. The crossbeam comprises a left group of longitudinal rods, a right group of longitudinal rods, a front cross bar, and a rear cross bar. Each of the left group of longitudinal rods and the right group of longitudinal rods is composed of two longitudinal rods. Each longitudinal rod is fixedly connected with the top of the corresponding fork lifting member of the double-fork lifting devices. The four parallel cross bars are fixedly connected with the left group of longitudinal rods and the right group of longitudinal rods. The hoisting apparatus utilize the double-fork gantry structure and achieves a maximum lifting height of 8 meters and maximum lifting weight of 10 tons.

Base comprises scaffold, and scaffold fills hydraulic supporting device, and hydraulic supporting device four hydraulic cylinder collaborative works, fill mobile device bottom scaffold; During operating state, the expansion link of hydraulic cylinder is propped up, supporting on the ground, mobile device not with earth surface, hydraulic cylinder bears whole load; When needs are mobile, the expansion link of hydraulic cylinder is retracted, and mobile device and earth surface, hydraulic cylinder does not directly contact with ground, realizes the indoor movement among a small circle of whole boom hoisting.
Transformer crane device of the present invention adopts double shear V shape gantry structure, and maximum lift height can reach 8 meters, maximum weight lifting can reach 12 tons.This apparatus design becomes composite type modular construction pattern, and lifting adopts hydraulic-driven technology.Each assembly of component devices (as scissors rod lift assemblies, crossbeam) is all modular organization, can assemble according to actual needs, realize the lifting of differing heights, amplitude, is convenient to carry out Mission Operations in the interior space.In addition, this boom hoisting is equipped with different suspender, as steel cable, woven belt etc., realizes the lifting requirement of different objects.
Accompanying drawing explanation
Below in conjunction with drawings and Examples, the invention will be further described.
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.
Embodiment
The boom hoisting of a kind of indoor various transformer grade gas-insulated switchgear device, comprise left and right base 1,2, left and right base is installed respectively the left and right pair of scissor lifting device 3,4 be elevated by left and right Hydraulic Cylinder, the top dress crossbeam 5 of left and right pair of scissor lifting device, crossbeam is equipped with and promotes the suspension hook that transformer hangs bell jar; On crossbeam, dress detects the whether consistent displacement transducer 6 of left and right pair of scissor lifting device adjustable height; Displacement transducer is connected with control module 7, and the sync control device 13 that main frame 8 and the left and right hydraulic cylinder 11,12 of control of control module are synchronized with the movement is connected; Crossbeam comprises left and right group of vertical pole and two, front and back cross bar, and left and right group of vertical pole is made up of two vertical poles respectively, and every root vertical pole is fixedly connected with the top of a scissors fork elevating part of two scissor lifting device; Four cross bars be parallel to each other are fixedly connected with left and right two groups of vertical poles.
During work, send instruction by the main frame of control system, left and right hydraulic cylinder works, left and right Hydraulic Cylinder left and right pair of scissor lifting device, drive crossbeam to rise, crossbeam hangs bell jar by hook transformer; Whether the left and right pair of scissor lifting device adjustable height that employing displacement transducer carries out detecting crossbeam both sides be consistent, and Real-time Feedback, if there is error, adjusted by control system, reach the synchronization job of both sides lift height, guarantee to be promoted the balance of object in lifting process.
Base comprises scaffold, scaffold fills hydraulic supporting device 9, and hydraulic supporting device four hydraulic cylinder collaborative works, fill mobile device 10 bottom scaffold; During operating state, the expansion link of hydraulic cylinder is propped up, supporting on the ground, mobile device not with earth surface, hydraulic cylinder bears whole load; When needs are mobile, the expansion link of hydraulic cylinder is retracted, and mobile device and earth surface, hydraulic cylinder does not directly contact with ground, realizes the indoor movement among a small circle of whole boom hoisting.Realize co-operating hydraulic module 14 by the main frame 8 of control system to control, thus complete the control of four supporting cylinders in bottom.
