The utility model has removed carrying pole beam type structure, uses hydraulic cylinder instead and is directly hinged on equalizer bar.So greatly shortened the stress flow line length of bascule, strengthened the non-deformability of bascule, thereby pretightning force can be better provided.
Summary of the invention
Problem to be solved in the utility model is to provide a kind of milling train top roll bascule, be particularly suitable for that two rollers that roll surface width is larger are thick, finish rolling is unidirectional or reversable mill, upper roll structure is played to counterpoise and the effect that pretightning force is provided, reduce the impact of steel part pair roller system.
For solving the problems of the technologies described above, the technical solution adopted in the utility model is:
A kind of milling train top roll bascule is provided, comprises by two horizontal girders and some balance roof beams structure vertically forming to tie-beam;
The two ends tie-beam of balance roof beam structure is hinged with the pistons end of balance hydraulic cylinder respectively, and balance hydraulic cylinder is arranged in the hydraulic cylinder seat being fixed on machine body,
Two horizontal girders of balance roof beam structure and the upper roll structure of lathe are affixed, and upper roll structure can pull up and down along with balance roof beam structure is balanced hydraulic cylinder vertical direction.
Further, also comprise bearing pin, the hinged bearing pin that is just provided with of pistons end of described tie-beam and balance hydraulic cylinder.
Further, described upper roll structure is provided with the junction of the horizontal girder of balance roof beam structure the groove matching with horizontal girder shape, and after installing, laterally girder is lying in groove.
Further, the 1.5-2 that the material thickness of the tie-beam of described balance roof beam structure is horizontal girder doubly.
Advantage and the good effect that the utlity model has are: the utility model has removed carrying pole beam type structure, use double hydraulic cylinder instead and are directly hinged on equalizer bar.So greatly shortened the stress flow line length of bascule, strengthened the non-deformability of bascule, thereby pretightning force can be better provided.

The specific embodiment
As shown in Fig. 1 and 2 and 5, existing milling train is all provided with single hydraulic cylinder bascule, is used for guaranteeing rolling accuracy and reduces the impact to bearing and roller system.When the roll surface width of roll is excessive, the weight of roller system obviously promotes, and causes so the stressed increase of single hydraulic cylinder, stricter to the requirement meeting of hydraulic cylinder, has improved cost.And shoulder pole girder length obviously lengthens in the single cylinder bascule of employing shoulder pole girder, can make its distortion strengthen, two ends, left and right discontinuity causes whole equipment to be partial to some directions.Greatly weakened the ability that pretightning force is provided.The long-term precision of its equipment of using can not guarantee, affects service life of equipment, has certain potential safety hazard simultaneously, can cause damage to equipment and personnel.
Milling train top roll bascule, has changed shoulder pole girder structure thick and heavy in existing design as shown in Figures 3 and 4.Made into comprise by two horizontal girders and some balance roof beams structure 1 vertically forming to tie-beam; Wherein two horizontal girders play the effect of supporting upper roll structure 5 that connects.The top roll structures shape that two distances with horizontal girder connect according to centre.Somely vertically to tie-beam, be used for affixed 2 horizontal girders, its quantity is according to being laterally provided with two vertically to tie-beam in girder length decision the utility model scheme, for the horizontal girder of big-length more, can increase several and vertically to tie-beam, gain in strength, the stability during work of assurance equipment.
The two ends tie-beam of balance roof beam structure 1 is hinged with the pistons end of balance hydraulic cylinder 4 respectively.Use hinged mode and do not use welding to wait to be fixedly connected with to make coupling part have certain free activity space, when avoiding milling train work rolled plate, excessive active force makes connecting portion fracture cause potential safety hazard.Articulated manner can increase again activity space to be had and can increase service life.Balance hydraulic cylinder 4 is arranged in the hydraulic cylinder seat 3 being fixed on machine body.Even if the layout of two balance hydraulic cylinders 4 makes whole device stress balance also can complete stably the operation of rolling in the situation that of larger load.For the larger milling train of roll surface width also can uniform more balance hydraulic cylinder 4 to meet stability and the production efficiency of whole bascule.This programme only be take the milling train top roll bascule of two balance hydraulic cylinders 4 and is introduced as example.
Two horizontal girders of balance roof beam structure 1 and the upper roll structure 5 of lathe are affixed, and upper roll structure can be balanced hydraulic cylinder 4 in the vertical directions along with balance roof beam structure 1, pulls up and down.Because balance hydraulic cylinder 4 self exists certain Flexible change scope, at steel plate, enter mill milling and contact with roll structure on milling train 5 simultaneously, larger impulsive force can make roll structure 5 in cylinder moving direction, have certain displacement, alleviates impulsive force.Initiatively start balance hydraulic cylinder 4 and move up and down the space of both having adjusted upper roll structure 5 and lower roll structure centre, to adapt to the steel plate of different-thickness, be rolled simultaneously.
Also comprise bearing pin 2, the hinged bearing pin 2 that is just provided with of pistons end of described tie-beam and balance hydraulic cylinder 4.By bearing pin 2, undertaken hingedly, when any one separate part damages, be convenient to rapid-maintenance, enhance productivity.
Described upper roll structure 5 is provided with the junction of the horizontal girder of balance roof beam structure 1 groove matching with horizontal girder shape, and after installing, laterally girder is lying in groove.Such design can better be located fast, realizes quick dispatch.
The material thickness of the tie-beam of described balance roof beam structure 1 is 1.5-2 times of horizontal girder.Because horizontal girder is subject to the possibility that the horizontal power of pullling has middle tie-beam to disconnect the milling train work time, so thickening the thickness of tie-beam, overstriking can better gain in strength, increase the service life.
The course of work of the present utility model: two horizontal girders and be somely vertically welded into balance roof beam structure 1 to tie-beam; The two ends tie-beam of balance roof beam structure 1 is hinged with the pistons end of balance hydraulic cylinder 4 respectively, in the hydraulic cylinder seat 3 of balance hydraulic cylinder 4 on being fixed in machine body, two horizontal girders of balance roof beam structure 1 and the upper roll structure 5 of lathe are affixed, and upper roll structure can pull up and down along with balance roof beam structure 1 is balanced hydraulic cylinder 4 vertical directions.
According to the steel plate thickness of required compacting, control balance hydraulic cylinder 4 and move up and down, to adjust the gap of upper roll structure 5 and lower roll structure.Send into steel plate and reduce thickness by pressure presed-steel plate between upper roll structure 5 and lower roll structure.The scope that in the course of work, the pretightning force of balance hydraulic cylinder 4 self changes can, so that top roll structure 5 has certain upper-lower position to rise and fall adapts to local defect projection on steel plate, be protected whole milling train stable operation.
Above embodiment of the present utility model is had been described in detail, but described content is only preferred embodiment of the present utility model, can not be considered to for limiting practical range of the present invention.All equalization variations of doing according to the utility model scope and improvement etc., within all should still belonging to this patent covering scope.
