Description

Modularized combination type voltage transformer bell jar lifting appliance
Technical field
The utility model relates to a kind of voltage transformer bell jar lifting appliance.
Background technology
In prior art, the lifting of indoor transformer bell jar, the lifting facility that general employing is common, needs to destroy building structure and just can operate in construction, and the technical ability impact of operating personal is large, and serviceability is undesirable, needs to be improved further.
Summary of the invention
The purpose of this utility model is to provide a kind of rational in infrastructure, the modularized combination type voltage transformer bell jar lifting appliance of favorable working performance.
Technical solution of the present utility model is:
A kind of modularized combination type voltage transformer bell jar lifting appliance, it is characterized in that: comprise left and right base module, left and right base module is installed respectively the left and right pair of scissors fork elevating module be elevated by left and right Hydraulic Cylinder, the top dress crossbeam module of left and right pair of scissors fork elevating module, crossbeam module is equipped with and promotes the suspension hook that voltage transformer hangs bell jar; In crossbeam module, dress detects the whether consistent displacement pickup of left and right pair of scissors fork elevating module adjustable height; Displacement pickup is connected with control system, and the sync control device that control system is moved with control left and right hydraulic cylinder synchronous is connected; Described pair of scissors fork elevating module is made up of two scissors fork elevating parts, each scissors fork elevating part is made up of multiple scissor unit, each scissor unit is made up of the scissors rod that two are connected by central pin shaft, arranges the disk stop pin jack that a circle coordinates with disk stop pin two scissors rod connecting portion peripheries.
The utility model transformer crane device 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 compound 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 lifting appliance is equipped with different suspender, as steel cable, canvas belt etc., realizes the lifting requirement of different objects.Lifting appliance is designed to three large modules: Hydraulic Double scissors fork elevating module, base module and crossbeam module.Lifting module realizes elevating function, base module realizes supporting and complete machine locomotive function, crossbeam module is connected with bell jar or other appendages by hawser or suspension hook, lift by crane different parts, ensure that the process of hoisting meets maintenance craft and quality loop (GB1094.1-2) in State Grid Corporation of China's " power transformer general provisions ".
Accompanying drawing explanation
Below in conjunction with drawings and Examples, the utility model is described in further detail.
Fig. 1 is the structural representation of the utility model embodiment.
Fig. 2 is the principle of work schematic diagram of control system.
Fig. 3 is scissor block construction schematic diagram.
Detailed description of the invention
A kind of modularized combination type voltage transformer bell jar lifting appliance, comprise left and right base module 1,2, left and right base module is installed respectively the left and right pair of scissors fork elevating module 3,4 be elevated by left and right Hydraulic Cylinder, the top dress crossbeam module 5 of left and right pair of scissors fork elevating module, crossbeam module is equipped with and promotes the suspension hook that voltage transformer hangs bell jar; In crossbeam module, dress detects the whether consistent displacement pickup 6 of left and right pair of scissors fork elevating module adjustable height; Displacement pickup is connected with control module 7, and the sync control device 13 that main frame 8 and the left and right hydraulic actuating cylinder 11,12 of control of control module are synchronized with the movement is connected;
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 scissors fork elevating module, drive crossbeam module to rise, crossbeam module hangs bell jar by hook voltage transformer; Whether the left and right pair of scissors fork elevating module adjustable height that employing displacement pickup carries out detecting crossbeam module 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 module comprises bearer frame, bearer frame fills hydraulic supporting device 9, and hydraulic supporting device four hydraulic actuating cylinder collaborative works, fill mobile device 10 bottom bearer frame; During mode of operation, the expansion link of hydraulic actuating cylinder is propped up, supporting on the ground, mobile device not with earth surface, hydraulic actuating cylinder bears whole load; When needs are mobile, the expansion link of hydraulic actuating cylinder is retracted, and mobile device and earth surface, hydraulic actuating cylinder does not directly contact with ground, realizes the indoor movement among a small circle of whole lifting appliance.Realize concerted action hydraulic module 14 by the main frame 8 of control system to control, thus complete the control of four supporting cylinders in bottom.
Two scissors fork elevating module, considers in indoor use, needs manpower to move into and takes out of, and this module has some scissors rods that can singlely move to combine, and every four scissors rods form a little module, and the quantity of little module highly can increase and decrease along with lifting.
Described pair of scissor lifting device is made up of two scissors fork elevating parts, each scissors fork elevating part is made up of multiple scissor unit 15, each scissor unit is made up of the scissors rod that two are connected by central pin shaft, arranges the disk stop pin jack 17 that a circle coordinates with disk stop pin 16 two scissors rod connecting portion peripheries.When bell jar lifting appliance is in the process risen or decline, scissor unit and disk stop pin are in released state, and now, two scissors rods of scissor unit can relatively rotate, thus realize lifting appliance lifting; When require lifting appliance remain on a certain height motionless time, inserted by disk stop pin in the corresponding aperture of scissor unit, then two scissors rods cannot do relative motion, and it is motionless that lifting appliance will remain on a certain height and position.
