Abstract
A multi-cylinder lifting platform comprises a base, a lifting system, an operation platform, and an electrical hydraulic control mechanism supplying hydraulic pressure to the lifting system. The lifting system comprises a plurality of hydraulic lifting mechanisms which lift synchronously; and each hydraulic lifting mechanism respectively comprises an oil cylinder jacket fixedly arranged on the base and a multi-stage telescopic oil cylinder arranged inside the oil cylinder jacket, wherein the tail end of the multi-stage telescopic oil cylinder is fixedly connected with the operation platform. The multi-cylinder lifting platform is characterized in that connecting frames are fixedly connected among a plurality of oil cylinder jackets; each connecting frame comprises a connecting plate parallel to the bottom surface of the operation platform; and both the bottom surfaces of the operation platform and the connecting plate are provided with through holes, the positions of which correspond to one another. The Multi-cylinder lifting platform can realize whole carrying-moving.
Description
Technical field
The present invention relates to a kind of multi-cylinder lift work platform.
Background technology
When machining large workpiece (as reactor pressure vessel etc.), because workpiece to be machined is bulky, therefore often need to utilize liftable service platform that the operating personnel is risen to higher position, allow the operating personnel carry out construction operation in the outside of pressure container.Be mainly used in lifting workman's jacking equipment at present, be by service platform mostly and be fixedly installed on ground a plurality of column and constitute, this service platform is around one week of workpiece, the bottom of service platform is provided with Connection Block, Connection Block and column are by being threaded, when Connection Block rotates by motor-driven, can promote service platform and move up, thus the height of lifting service platform.Yet for general machine up factory building, huge service platform not only can not move, and the high a plurality of columns that tower also can interfere with the hoist cable on factory building top, particularly when carrying miscellaneous equipment or large-scale workpiece, bumps easily.
Summary of the invention
The purpose of this invention is to provide a kind of multi-cylinder lifting platform that can make things convenient for integral shift.
For achieving the above object, the technical solution adopted in the present invention is: a kind of multi-cylinder lifting platform, comprise base, jacking system, service platform, the electrohydraulic control mechanism of hydraulic pressure is provided for described jacking system, described jacking system comprises the hydraulic efficiency elevation structure of a plurality of synchronization liftings, each described hydraulic efficiency elevation structure comprises the oil cylinder overcoat that is fixedly installed on the described base respectively, be arranged on the multi-stage expansion oil cylinder in the described oil cylinder overcoat, the extreme end of described multi-stage expansion oil cylinder and described service platform are fixedly connected, be fixedly connected with link span between a plurality of described oil cylinder overcoats, described link span comprises the connecting panel of the bottom surface that is parallel to described service platform, all offer through hole on the bottom surface of described service platform and the described connecting panel, and the position of the through hole of offering on the bottom surface of described service platform and the described connecting panel is corresponding.
The present invention's technical scheme further is: described multi-cylinder lifting platform comprises also and described service platform and connecting panel bonded assembly suspension ring removably that described suspension ring pass the bottom surface of described service platform and the through hole on the described connecting panel.
Further, an end diameter chap of described suspension ring, the other end has shackle.
Perhaps, the tommyhead bolt that described suspension ring comprise, be threadedly connected to the nut of described bolt, the end of described bolt has shackle.
Advantage of the present invention is: the present invention is provided with through hole on the base of service platform and connecting panel, when needs lift this lifting table, make the suspension hook of factory building suspension transferring machine can pass each through hole, perhaps passes suspension ring, thereby the lifting table integral hoisting is moved.
Description of drawings
Accompanying drawing 1 is a front view of the present invention;
Accompanying drawing 2 is a birds-eye view of the present invention;
Accompanying drawing 3 is a suspension ring bonded assembly scheme drawing;
Wherein: 1, base; 2, lifting mechanism; 3, service platform; 4, oil cylinder overcoat; 5, connecting panel; 6, reinforced rib; 7, through hole; 8, suspension ring; 9, hydraulic motor.
Specific embodiment
The present invention is described in detail below in conjunction with accompanying drawing.
A kind of multi-cylinder lifting platform, comprise base 1, jacking system, service platform 3, the electrohydraulic control mechanism of hydraulic pressure is provided for jacking system, jacking system comprises the hydraulic efficiency elevation structure 2 of a plurality of synchronization liftings, each hydraulic efficiency elevation structure 2 comprises the oil cylinder overcoat 4 that is fixedly installed on the base 1 respectively, be arranged on the multi-stage expansion oil cylinder in the oil cylinder overcoat 4, because what accompanying drawing provided is that multi-cylinder lifting platform is in the front view under the contraction state, the multi-stage expansion oil cylinder is positioned at the inside of oil cylinder overcoat 4, therefore invisible among the figure, the extreme end of multi-stage expansion oil cylinder and service platform 3 are fixedly connected.When the multi-stage expansion oil cylinder stretches out step by step, service platform 3 can be given rise to eminence.
As shown in Figure 2, multi-cylinder lifting platform is circular, a plurality of lifting mechanisms are evenly distributed on the circumference, be fixedly connected with link span between a plurality of oil cylinder overcoats 4, link span comprises the connecting panel 5 of the bottom surface that is parallel to service platform 3, all offer through hole 7 on the bottom surface of service platform 3 and the connecting panel 5, and the position of the through hole of offering on the bottom surface of service platform 3 and the connecting panel 57 is corresponding.The both sides of each lifting mechanism 2 are distributed with through hole 7.When the carrying multi-cylinder lifting platform, can carry by the factory building suspension transferring machine, as long as the suspension hook of factory building suspension transferring machine is passed simultaneously a plurality of through holes of offering on the bottom surface of service platform 3 and the connecting panel 5, bottom surface and connecting panel 5 owing to service platform 3 when not needing to carry are separated from each other, so service platform 3 can free lifting.
Preferably, multi-cylinder lifting platform comprises also and service platform 3 and connecting panel 5 bonded assembly suspension ring 8 removably that suspension ring 8 pass the bottom surface of service platform 3 and the through hole 7 on the connecting panel 5.The suspension hook of factory building suspension transferring machine passes this suspension ring 8 multi-cylinder lifting platform is allocated and transported away.
As shown in Figure 3, this hangs 8 head diameter chap, and the other end has shackle, and in the time of installation, the head of these suspension ring 8 is positioned at the below of connecting panel 5, because the head diameter of suspension ring 8 greater than the internal diameter of through hole 7, therefore can not come off in lifting.
Perhaps, suspension ring 8 can also be made up of tommyhead bolt, the nut that is threadedly connected to bolt, and the end of bolt has shackle, nut is set can prevents that tommyhead bolt from coming off, the staff is connected suspension ring 8 after can once all suspension ring being installed successively again with the suspension hook of factory building suspension transferring machine.
