Description
Technical field
The present invention relates to a kind of pushers with side directive wheel.
Background technique
In iron and steel enterprise's mill, pusher is used to push on steel billet the roller-way or rack of subsequent processing.Push away steel
Machine generallys use hydraulic cylinder and provides power.Since steel billet length dimension specification is more, pusher when pushing different size steel billets, by
In steel billet not necessarily at pusher center, the payload size of each Driven by Hydraulic Cylinder is different, it may appear that nonsynchronous situation is moved, because
This pusher movement mechanism needs to guarantee that the movement of multiple hydraulic cylinders is same by the way of hydraulic circuit synchronization or mechanical synchronization
Step.Hydraulic synchronization is frequently with hydraulic proportion valve position control mode at present, but hydraulic proportion valve position control loop cost compared with
It is high.For the steel billet of long size, pusher mechanical synchronization mode is realized frequently with equal carrier aircraft and is synchronized, and pusher moves not by unbalance loading
It influences, but mechanical structure is relative complex.
Summary of the invention
Goal of the invention: the present invention proposes a kind of mechanical synchronization formula pusher with side directive wheel, pushes away steel with guide rod constraint
Machine moves in the straight direction, and configuration side directive wheel prevents guide rod flexible deformation.
The present invention is as follows using technical solution:
A kind of pusher with directive wheel, including guide rail, guiding wheel component, pusher frame, hydraulic cylinder, hydraulic cylinder base,
Guide rod, guide rod pedestal.
Hydraulic cylinder is mounted on hydraulic cylinder base, and tailpiece of the piston rod and pusher frame are hinged, provides power for pusher.It leads
It is rigidly attached on pusher frame to bar one end, guide rod is assemblied in tight with guide rod base holes in the pilot hole of guide rod pedestal
Close fit.Because guide rod is constrained by the shaft hole matching of guide rod pedestal, when hydraulic cylinder movement, force pusher frame along guide rod
Axially move synchronously.
Guiding wheel component is mounted below pusher frame, is carry pusher frame and is walked on guide rail.Be oriented to wheel component by
Side directive wheel is arranged in guide wheel bracket, horizontal bearing wheel, side directive wheel, eccentric shaft, directive wheel axle sleeve composition, guide rail two sides,
Side directive wheel quantity can be multiple.Horizontal bearing wheel is mounted on guide wheel bracket, mainly carries the weight of entire pusher.
Guide wheel bracket installation secures directive wheel axle sleeve, and side directive wheel is assemblied in directive wheel axle sleeve by eccentric shaft, eccentric shaft dress
It fits in directive wheel axle sleeve polygon slot, by the gap for changing assembly angle adjustable side directive wheel and guide rail.Use with
On gap adjustment structure can eliminate multiple side directive wheels and guide rail cooperation gap deviation.
When pusher is in unbalance loading operating condition, flexible deformation of the guide rod at more long-range can be bigger, and side directive wheel is to lead
The lateral supporting forces perpendicular to the guide rod direction of motion are provided to bar, prevent guide rod from deforming.Through the above technical solutions, making to push away
Steel rack axially pushes steel billet load along guide rod, and the movement of implementation mechanism is synchronous.
The utility model has the advantages that the present invention uses the tight fit of guide rod and guide rod base holes, steel is pushed away along axially directed realization
The mechanical synchronization of rack, setting side wheel design can prevent the flexible deformation under guide rod unbalance loading operating condition, which simply may be used
It leans on.By adjusting the gap of side directive wheel and guide rail, certain installation foozle can be eliminated.In conclusion present device
It is simple with structure, high reliablity, advantage convenient for installation and maintenance.

Specific embodiment
The preferred embodiment of the present invention is described in further detail with reference to the accompanying drawing.
As shown in Figure 1, pusher of the present invention includes guide rail 1, guiding wheel component 2, pusher frame 3, hydraulic cylinder 4, hydraulic cylinder
Pedestal 5, guide rod 6, guide rod pedestal 7.
Hydraulic cylinder 4 is mounted on hydraulic cylinder base 5, and tailpiece of the piston rod and pusher frame 3 are hinged, provides power for pusher.
6 one end of guide rod is rigidly attached on pusher frame 3, and guide rod 6 is assemblied in the pilot hole of guide rod pedestal 7 and guide rod bottom
The axis hole of seat 7 is fitted close.Because guide rod 6 is forced pusher when hydraulic cylinder 4 acts by the fiting constraint of guide rod pedestal 7
Frame 3 is axially moved synchronously along guide rod.
As shown in Fig. 2, guiding wheel component 2 is mounted on 3 lower section of pusher frame, pusher frame 3 is carry in 1 uplink of guide rail
It walks.Guiding wheel component 2 is made of guide wheel bracket 9, horizontal bearing wheel 8, side directive wheel 12, eccentric shaft 11, directive wheel axle sleeve 10,
Side directive wheel 12 is arranged in 1 two sides of guide rail, according to operating condition need side directive wheel 12 quantity can be it is multiple.Horizontal bearing wheel 8
It is mounted on guide wheel bracket 9, mainly carries the weight of entire pusher.The installation of guide wheel bracket 9 secures directive wheel axle sleeve
10, side directive wheel 12 is assemblied in directive wheel axle sleeve 10 by eccentric shaft 11.11 upside directive wheel center line of eccentric shaft and guiding
Having a size of a, the gap between side directive wheel 12 and guide rail 1 is b for the biasing of axle sleeve center line.When shown position is gap b minimum.
As shown in Fig. 3 eccentric shaft adjustment structure schematic diagram, eccentric shaft polygon plug 14 is devised above eccentric shaft 11, is led
It is equipped with directive wheel axle sleeve polygon slot 13 to the top of axle sleeve 10, eccentric shaft polygon plug 14 is assemblied in directive wheel axle sleeve
In polygon slot 13, by the gap b for changing assembly angle theta adjustable side directive wheel and guide rail.Its adjusting relationship is gap
The incrementss △ b=a-a*cos θ of b.Because multiple, multiple side directive wheels 12 and guide rail 1 has been set as needed in side directive wheel 12
Inevitably there is installation manufacture deviation and is eliminated certain by the gap of above structure adjustable side directive wheel 12 and guide rail 1 in cooperation
Foozle is installed, equipment installation and manufacture difficulty are reduced.
When encountering steel billet not at the center of pusher frame 3, left and right hydraulic cylinder 4 is by load force unevenness, and pusher has in addition
Certain impulse stroke, flexible deformation of the guide rod 6 at more long-range can be bigger, and side directive wheel 12 provides vertical for guide rod 6
Directly in the lateral supporting forces of the guide rod direction of motion, because multiple, therefore energy can be set as needed into the quantity of side directive wheel 12
Enough lateral supporting forces are provided for guide rod 6, to prevent guide rod 6 from deforming.By said mechanism scheme, make pusher frame 3
Steel billet load is axially pushed along guide rod, realizes that the movement of hydraulic cylinder 4 synchronizes.
The above is only a preferred embodiment of the present invention, it should be pointed out that: for the ordinary skill people of the art
For member, various improvements and modifications may be made without departing from the principle of the present invention, these improvements and modifications are also answered
It is considered as protection scope of the present invention.
