Description
Technical field
The utility model belongs to field of metallurgical equipment, is specifically related to a kind of roller mill working roll lifting device.
Background technology
In the cold rolling of metallurgical production or hot rolling technology, various working roll is widely used on production line, and change, maintenance work roller adopts the push-and-pull of working in coordination of traditional artificial and overhead traveling crane to realize usually, but due to working roll weight large, artificial method is not only lost time, and easily cause danger, in production roll change process, workshop overhead traveling crane can not may use due to equipment fault, and roll change work difficulty strengthens further, so various roller mill working roll lifting device arises at the historic moment.But, because working roll weight reaches hundreds of kilogram, and the lift arm of existing working roll lifting device mostly is integral structure, lift arm flexural deformation can be caused thus disequilibrium after Long-Time Service, in addition, the weight of working roll is directly carried by hydraulic hoisting machine, and Long-Time Service also can damage hydraulic hoisting machine.
Summary of the invention
The purpose of this utility model is for above-mentioned defect, provides a kind of lift arm not yielding, hydraulic hoisting machine non-damageable roller mill working roll lifting device.
Above-mentioned purpose is achieved through the following technical solutions:
A kind of roller mill working roll lifting device, comprise hydraulic hoisting machine and lift arm, described lift arm is made up of bearing and cantilever, described bearing is located at the top of hydraulic hoisting machine, pressure buffer groove is provided with in the below of described bearing and cantilever connecting portion, the securing member for adjusting cantilever balance is provided with in described cantilever, described securing member is made up of bolt, nut and disc spring, one end of described bolt is connected with bearing through cantilever, described nut is located at the other end of bolt and is positioned at cantilever, and described disc spring is located between nut and cantilever.
Described bearing is provided with support arm, and one end of described support arm is provided with pulley, and described hydraulic hoisting machine is provided with the slide rail matched with pulley.
The top of described cantilever is provided with manipulator, is provided with the runner matched with roller mill working roll in manipulator.
The utility model is by establishing pressure buffer groove in the below of bearing and cantilever connecting portion, when promoting working roll, can the immense pressure that carries of buffering hydraulic elevator, effectively extend the service life of hydraulic hoisting machine, the effect of securing member is the balance regulating cantilever, after repeatedly use causes cantilever sagging, by locking nut again by cantilever adjustment.Lift arm is reinforced in the effect of support arm, prevents it sagging.Runner on manipulator is used for twist rollers operation roll of mill, checks the fault of working roll, makes operation more laborsaving.The features such as the utility model can service life of significant prolongation lift arm and hydraulic hoisting machine, has structure simple, easy to operate.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
In figure: 1-hydraulic hoisting machine, 2-lift arm, 3-bearing, 4-cantilever, 5-pressure buffer groove, 6-securing member (61-bolt, 62-nut, 63-disc spring), 7-support arm, 8-pulley, 9-manipulator, 10-runner.
Detailed description of the invention
