Specific embodiment
The technical solution of the utility model is described in further detail below in conjunction with Figure of description.
As shown in Figs. 1-2, high-power transformer steering mechanism, including pivoting support 1, set on 1 bottom periphery of pivoting support
One pushing mechanism 3 for enclosing tooth-like track 2, being connected with the support inner ring 101 of pivoting support 1, it is equal that tooth-like track 2 is equipped with multiple circumferential directions
The tooth pushing 201 of even setting, tooth pushing 201 are equipped with inclined-plane 20102 and vertical pushing surface 20101 obliquely, and pushing mechanism 3 includes liquid
Compressing cylinder 301, one end of hydraulic cylinder 301 are connected with the support inner ring 101 of pivoting support 1；The other end of hydraulic cylinder 301 with
Tooth-like track 2 matches, and the flexible support inner ring 101 for pushing pivoting support 1 of the push rod 303 of hydraulic cylinder 301 rotates.
In order to which steering work is better achieved, 101 outer one end welding support 102 of inner ring, the hydraulic cylinder 301 are supported
Push rod 303 be connected with bracket 102 by shaft, the cylinder ends of hydraulic cylinder 301 equipped with pushed section 302, pushed section 302 with it is tooth-like
Track 2 matches.Since push rod 303 passes through, shaft is connect with bracket 102 and pushed section 302 and tooth-like track 2 match, in hydraulic oil
When cylinder 301 ejects, by pushed section 302 and tooth-like 2 phase top of track, keep oil cylinder position constant, push rod 303 pushes bracket by shaft
102, since bracket 102 is to be welded and fixed, and then support inner ring 101 is driven to rotate with support inner ring 101, turn an angle
Afterwards, oil cylinder recycles push rod 303, and transformer weight due to support inner ring 101 and thereon is big, at this point, oil cylinder and pushed section 302 are left
It with the matching of tooth-like track 2, moves forward, and next tooth of pushed section 302 and tooth-like track 2 is made to match, complete once to turn to dynamic
Make, and according to circumstances waits go to action next time.
In order to reduce 302 moving resistance of pushed section when oil cylinder recycling, pushed section 302 is the roller bearing being rotatablely connected with cylinder body.Rolling
Axis is pivoting friction when mobile relative to tooth-like track 2, and in oil cylinder recycling, the mobile resistance in pushed section 302 is small.
In order to which the support to pushed section 302 is better achieved, pushing surface 20101 is in interior concaved circular cambered surface.Interior concave arc pushing surface 20101
Structural strength is big, and the support of power can be preferably carried out to pushed section 302.
In order to realize stronger thrust, steering mechanism sets that there are two pushing mechanisms 3, respectively the first pushing mechanism and second
Pushing mechanism, the hydraulic cylinder in the first pushing mechanism is the first hydraulic cylinder 4, hydraulic in the second pushing mechanism
Oil cylinder is the second hydraulic cylinder 5, the first hydraulic cylinder 4, the second hydraulic cylinder 5 by the first reversal valve 6, the second reversal valve 7 with
Hydraulic generator 8 is connected.Thrust is stronger, and two pushing mechanisms 3 can be more easier and more smoothly realize to turn to push.
In order to reduce manufacturing cost, the interval of tooth pushing 201 is arranged, and gap is equipped between two tooth pushings 201.Effectively reduce tooth pushing
201, reduce manufacturing cost.
In order to keep tooth-like 2 structure of track stronger, tooth-like track 2 includes base ring 202, inner ring 204, outer ring 203, base ring
202 are located at the top of inner ring 204 and outer ring 203, and tooth pushing 201 is welded on base ring 202, inner ring 204 and outer ring 203.The structure
Keep tooth-like track 2 stronger, tooth pushing 201 is welded and fixed that effect is good, and overall structural stability is good, can bear that biggish oil cylinder is counter to be pushed away
Power.
In order to reduce the manufacturing cost of tooth pushing 201, tooth pushing 201 is stamped to form by metal plate.Stamped, it is at low cost, add
Work is convenient.
The height of outer ring 203 is higher than inner ring 204, is moved outside pushing mechanism 3 with limiting.
When hydraulic cylinder 301 works, pushed section 302 and the pushing surface 20101 of tooth pushing 201 offset, and stretch the push rod 303 of oil cylinder
It is long, push the support inner ring 101 of pivoting support 1 to rotate, after oil cylinder stretches out the stroke of push rod 303, hydraulic cylinder 301 is returned
Contracting, pushed section 302 are detached from and offset in pushing surface 20101, slide along track, later fall into down along the sliding of inclined-plane 20102 of tooth
The jacking position of one tooth, that is, carry out the jacking of hydraulic cylinder 301 next time, in this way, just making the flexible of hydraulic cylinder 301 repeatedly
Conversion of motion is the rotary motion of pivoting support 1, realizes and turns to.
The hydraulic system of steering mechanism is as shown in figure 3, the first hydraulic cylinder 4, the second hydraulic cylinder 5 pass through the first reversal valve
6, the second reversal valve 7 is connected with hydraulic generator 8.
By the setting of two reversal valves and the identical hydraulic cylinder of volume, three kinds for realizing two oil cylinders of rotating mechanism
Operating mode.
Mode one: when the second reversal valve 7 is in A, the first reversal valve 6 is in C.Second hydraulic cylinder, 5 upper and lower cavity
Oil circuit locking, the second hydraulic cylinder 5 are failure to actuate.And the two cavity oil up and down of the first hydraulic cylinder 4 respectively with hydraulic generator 8 two
Road pipeline connection can make the first hydraulic cylinder 4 carry out stretching motion by operating hydraulic generator 8.This mode is mainly
It is used when rotating mechanism is in underload.
Mode two: when the second reversal valve 7 is in A, the first reversal valve 6 is in A.First hydraulic cylinder 4 and second
Intercommunication between the epicoele of hydraulic cylinder 5.When operation hydraulic generator 8 makes its L mouthfuls of generation pressure, to push the first hydraulic cylinder
4 stretch out, and the epicoele that the oil liquid of 4 epicoele of the first hydraulic cylinder is extruded into the second hydraulic cylinder 5 promotes the second hydraulic cylinder 5 to return
The oil liquid of contracting, 5 cavity of resorption of the second hydraulic cylinder passes through hydraulic generator 8H mouthfuls of oil return.Otherwise work as hydraulic generator 8H mouthfuls of generation pressure
When, push the second hydraulic cylinder 5 to stretch out, the oil liquid of 5 epicoele of the second hydraulic cylinder is extruded into the epicoele of the first hydraulic cylinder 4,
The oil liquid of first hydraulic cylinder 4 retraction, 4 cavity of resorption of the first hydraulic cylinder passes through hydraulic generator 8L mouthfuls of oil return.The mode can be real
The work that existing double oil cylinders alternately stretch, i.e., the second hydraulic cylinder 5 bounces back when the first hydraulic cylinder 4 is stretched, when the second hydraulic cylinder 5 is stretched
First hydraulic cylinder 4 retraction, in this way, waiting when rotating mechanism can be made to reduce oil cylinder retraction by operating hydraulic generator 8
Time accelerates operating rate.
Mode three: when the second reversal valve 7 is in B, the first reversal valve 6 is in B.First hydraulic cylinder 4 and second
The cavity of resorption of hydraulic cylinder 5 is connected to 8L mouthfuls of hydraulic generator together, and the epicoele of two oil cylinders together with 8H mouthfuls of companies of hydraulic generator
It is logical.Operation hydraulic generator 8 can make two oil cylinders are same to stretch with contracting.The mode mainly in the case where rotating mechanism meets larger situation,
It is used when increasing rotation torque.
High-power transformer steering mechanism and its working method shown in figure 1 above -2 are the specific implementations of the utility model
Example, has embodied the utility model in essence feature and progress, needs can be used according to actual, in opening for the utility model
Under showing, the equivalent modifications of shape, structure etc., the column in the protection scope of this programme are carried out to it.
