Description
Technical field
The utility model belongs to the large-tonnage multifunctional test machine, is specially adapted to a kind of multifunctional test machine beam balancing device that moving beam weight is large, adjust stroke length.
Background technology
At present, the structure of its existing multifunctional test machine comprises upper beam, column, moving beam, and the moving beam of some multifunctional test machine is fixed; Some liftable but lifting travel is little, in 1 meter, its moving beam weight is little, can be by motor-driven usually; The testing machine that some lifting travel is larger, usually below 4 meters, its moving beam weight is slightly heavy, and by the Driven by Hydraulic Cylinder lifting, this testing machine adopts key tooth fixed form when lifting, causes the uncontinuity of lifting travel.When maximum pressure when requiring to test reaches 8000 tons, moving beam can realize that continuous lifting travel reaches the large-tonnage multifunctional test machine of 10 meters, will cause so the excessive moving beam of the weight drive motor that required power is very large when lifting to drive.Therefore, the shortcoming and defect part for above-mentioned technology exists can realize continuous lifting and reduce driving power in order to make moving beam, reaches energy-conservation purpose.Research and develop new multifunctional test machine beam balancing device; Very necessary.
Summary of the invention
The utility model is intended to the shortcoming and defect that exists in above-mentioned technology, and provide not only reasonable in design, compact conformation, can be applicable to maximum pressure and reach 8000 tons, can realize that again continuous lifting travel reaches 10 meters, and have stable and reliable for performance, unbalance loading not, friction force is little, and a kind of multifunctional test machine beam balancing device is very easily used in energy-conservation and operation.
The purpose of this utility model is to adopt following technical scheme to realize: described multifunctional test machine moving beam balance device, comprise compensating cylinder, upper beam, column, moving beam, it is characterized in that: two compensating cylinders of the symmetrical installing in the two ends of described upper beam, be threaded connection on upper beam more than the bottom flange of described each compensating cylinder, sequentially install fovea superior ball pad, epirelief ball pad on the cylinder body thread segment of described upper top surface of the beam, realize that concavo-convex sphere is rotatably assorted; On the moving beam corresponding with the piston rod shift position of its compensating cylinder, be bolted support, the bottom of described piston rod is passed the transverse slat on support and is stretched outside plate, and recessed ball pad, lower protruding ball pad sequentially are threaded on the piston rod bottom outside stretching plate; Realize that concavo-convex sphere is rotatably assorted.
Principle of the present utility model and characteristics are described below:
(1) the utility model maximum pressure reaches 8000 tons, and 10 meters weight of coming the balance moving beam of the long stroke hydraulic cylinder-stroke of employing, driving mechanism only needs overcome friction to get final product in motion process, and the moving rate of the drive motor when having reduced lifting has reached energy-conservation purpose.
(2) adopt two ball ring connecting modes between hydraulic cylinder and entablature.
(3) cylinder plunger and moving beam junction arrange ball ring.For unbalance loading may occur in loading procedure, make moving beam tilt phenomenon occur, the application of ball ring makes the plunger rod of hydraulic cylinder be unlikely to bend, and guarantees the normal operation of hydraulic cylinder and sealing system.
The comprehensive above technical scheme of taking realizes the purpose of this utility model.
Compared with prior art, the utility model is not only reasonable in design, compact conformation, can be applicable to maximum pressure and reach 8000 tons, can realize that again continuous lifting travel reaches 10 meters, and have stable and reliable for performance, unbalance loading not, friction force is little, and the characteristics such as very convenient are used in energy-conservation and operation.
