Abstract

The utility model relates to a lifting device for an upper coil stripping trolley. The lifting device comprises a bearing platform, a four-connecting rod mechanism, wheels, a trolley base, an oil cylinder and slideways, wherein the four-connecting rod mechanism is arranged between the bearing platform and the trolley base, is connected with the bearing platform by a first fixing hinged joint point and is connected with the trolley base by a second fixing hinged joint point; the four-connecting rod mechanism is connected with the two wheels, one wheel is arranged in a slideway on the trolley base, and the other wheel is arranged in a slideway on the reverse side of the bearing platform; the fixing end of the oil cylinder is fixed to the bottom of the bearing platform; and a piston rod of the oil cylinder is connected with the two wheels by connecting rods. According to the lifting device, lifting is realized effectively by the four-connecting rod mechanism under the action of the oil cylinder, so that the lifting device has the advantages of simple and compact structure, safe and reliable performance, convenience for maintenance, and can be widely applied to the upper coil stripping trolley of a cold rolling unit.

Description

A kind of upper coil stripping car jacking system
Technical field
The utility model belongs to coil stripping car technical field on the cold rolling unit of metallurgical equipment, particularly a kind of upper coil stripping car jacking system.
Background technology
In field of metallurgical equipment, particularly cold rolling unit rolling before, the lifting of upper volume dolly is loaded onto reel of uncoiler with coil of strip; After the rolling end, the coil stripping car lifting is unloaded volume with coil of strip from reeler.The dolly lifting mainly is to rely on the vertical telescopic of oil cylinder coil of strip to be risen and decline.So just cause equipment huge, and civil Engineering Design, construction working amount are large.
Summary of the invention
In order to overcome the shortcoming of above-mentioned prior art, the purpose of this utility model is to provide a kind of upper coil stripping car jacking system, has simple in structure, performance safety failure-free advantage.
In order to achieve the above object, the technical scheme taked of the utility model is:
A kind of upper coil stripping car jacking system, comprise bearing platform 1, four-bar linkage 2, wheel 3, dolly chassis 4, oil cylinder 5, slideway 6, four-bar linkage 2 is installed between bearing platform 1 and the dolly chassis 4, four-bar linkage 2 links with bearing platform 1 by first A that is fixedly hinged, four-bar linkage 2 links with dolly chassis 4 by second B that is fixedly hinged, four-bar linkage 2 connects two wheels 3, wheel 3 is configured in the slideway 6 on the dolly chassis 4, another wheel 3 is configured in the slideway 6 on bearing platform 1 back side, the fixed end of oil cylinder 5 is fixed on bearing platform 1 bottom, and the piston rod of oil cylinder 5 connects two wheels 3 by connecting rod.
Characteristics of the present utility model are: under the effect of oil cylinder, realized lifting by a four-bar linkage actv..Have simple in structure, compact, performance safety, reliable, the advantage such as easy to maintenance can be widely used in the upper coil stripping car of cold rolling unit.
Description of drawings:
Accompanying drawing is structural representation of the present utility model.
The specific embodiment
The utility model is described in further detail below in conjunction with accompanying drawing.
A kind of upper coil stripping car jacking system, comprise bearing platform 1, four-bar linkage 2, wheel 3, dolly chassis 4, oil cylinder 5, slideway 6, four-bar linkage 2 is installed between bearing platform 1 and the dolly chassis 4, four-bar linkage 2 links with bearing platform 1 by first A that is fixedly hinged, four-bar linkage 2 links with dolly chassis 4 by second B that is fixedly hinged, four-bar linkage 2 connects two wheels 3, wheel 3 is configured in the slideway 6 on the dolly chassis 4, another wheel 3 is configured in the slideway 6 on bearing platform 1 back side, the fixed end of oil cylinder 5 is fixed on bearing platform 1 bottom, and the piston rod of oil cylinder 5 connects two wheels 3 by connecting rod.
Principle of work of the present utility model is:
When in the rising working process, 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 four-bar linkage 2 B that is fixedly hinged is motionless, just rotate, and first A that is fixedly hinged has both rotated upward movement, the wheel 3 of two other point of connection of four-bar linkage 2 is finally realized the rise of bearing platform 1 in the respectively slideway 6 beginnings rolling to the right of dolly chassis 4 and bearing platform 1;
When doing in the process in decline, the piston rod of oil cylinder 5 is retracted, the wheel 3 of two other point of connection of four-bar linkage 2 rolls left in slideway 6 beginnings of dolly chassis 4 and bearing platform 1 respectively, second of four-bar linkage 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.
