Abstract
The invention discloses a lifting device. The lifting device comprises a bearing platform, a four-bar linkage mechanism, two wheels, a trolley chassis, a cylinder and slide rails, wherein the four-bar linkage mechanism is arranged between the bearing platform and the trolley chassis, is in chain connection with the bearing platform through a first fixed hinge joint, is in chain connection with the trolley chassis through a second fixed hinge joint, and is connected with the two wheels; one wheel is arranged in the slide rail on the trolley chassis, and the other wheel is arranged on the slide rail on the back side of the bearing platform; a fixed end of the cylinder is fixed at the bottom of the bearing platform; a piston rod of the cylinder is connected with the two wheels through a connecting rod; and under the action of the cylinder, the lifting device can move up and down efficiently through the four-bar linkage mechanism. The lifting device has the advantages of simple and compact structure, safe and reliable performance, convenience in maintenance and the like, and can be widely used in a coil loading/unloading trolley of a cold rolling mill unit.
Description
Technical field
The invention belongs to coil stripping car technical field on the cold rolling unit of metallurgical equipment, particularly a kind of lowering or hoisting gear.
Background technology
In field of metallurgical equipment, before particularly cold rolling unit is rolling, on roll up dolly and go up and down coil of strip is loaded onto reel of uncoiler; After the rolling end, coil stripping car goes up and down coil of strip is unloaded volume from coiling machine.The dolly up-down mainly is to rely on the vertical flexible of oil cylinder coil of strip to be risen and decline.So just cause equipment huge, and civil Engineering Design, construction working amount are big.
Summary of the invention
In order to overcome the shortcoming of above-mentioned prior art, the object of the present invention is to provide a kind of lowering or hoisting gear, have advantage simple in structure, that performance is safe and reliable.
In order to achieve the above object, the technical scheme taked of the present invention is:
A kind of lowering or hoisting gear; Comprise bearing platform 1, quadric chain 2, wheel 3, dolly chassis 4, oil cylinder 5, slideway 6, quadric chain 2 is installed between bearing platform 1 and the dolly chassis 4, and quadric chain 2 links with bearing platform 1 through first A that is fixedly hinged; Quadric chain 2 links with dolly chassis 4 through second B that is fixedly hinged; Quadric chain 2 connects 3, one wheels 3 of two wheels and is configured in the slideway 6 on the dolly chassis 4, and another wheel 3 is configured in the slideway 6 on bearing platform 1 back side; The stiff end of oil cylinder 5 is fixed on bearing platform 1 bottom, and the piston rod of oil cylinder 5 connects two wheels 3 through connecting rod.
Characteristics of the present invention are: under the effect of oil cylinder, effectively realized up-down through a quadric chain.Have simple in structure, compact, performance safety, reliable, advantage such as easy to maintenance can be widely used in the coil stripping car on cold rolling unit.
Description of drawings:
Accompanying drawing is a structural representation of the present invention.
The specific embodiment
Below in conjunction with accompanying drawing the present invention is described further.
A kind of lowering or hoisting gear; Comprise bearing platform 1, quadric chain 2, wheel 3, dolly chassis 4, oil cylinder 5, slideway 6, quadric chain 2 is installed between bearing platform 1 and the dolly chassis 4, and quadric chain 2 links with bearing platform 1 through first A that is fixedly hinged; Quadric chain 2 links with dolly chassis 4 through second B that is fixedly hinged; Quadric chain 2 connects 3, one wheels 3 of two wheels and is configured in the slideway 6 on the dolly chassis 4, and another wheel 3 is configured in the slideway 6 on bearing platform 1 back side; The stiff end of oil cylinder 5 is fixed on bearing platform 1 bottom, and the piston rod of oil cylinder 5 connects two wheels 3 through connecting rod.
Operation principle of the present invention is:
When in the rising course of work, the piston rod of oil cylinder 5 stretches out, because the bottom of oil cylinder 5 is fixed on the bearing platform 1; So bearing platform 1 begins upwards to rise; Second of quadric chain 2 B that is fixedly hinged is motionless, just rotate, and first A that is fixedly hinged has both rotated and moves upward; The beginning on the slideway 6 of difference dolly chassis 4 and bearing platform 1 of the wheel 3 of two other tie point of quadric chain 2 is rolled to the right, finally realizes the rise of bearing platform 1;
When do in the process piston rod withdrawal of oil cylinder 5, the beginning rolling left on the slideway 6 of dolly chassis 4 and bearing platform 1 respectively of the wheel 3 of two other tie point of quadric chain 2 in decline; Second of quadric chain 2 B that is fixedly hinged is motionless, just rotate, and first A that is fixedly hinged has both rotated and moves downward; The final decline that realizes bearing platform 1, at this moment to be in the installation site the shortest for oil cylinder 5, be in bearing platform 1 below.
