Description
Technical field
The utility model relates to a kind of dredger steel pile maintenance rotating devices, belong to maintenance frock technical field.
Background technique
Current 3500 side cutter suction dredger, it is common to use piling bar table system is positioned using major and minor piling bar, and ship exists
In construction, major and minor piling bar is used alternatingly, and meets ship displacement, production needs, under different shales and sea situation, different is applied
Work and different damages is caused to piling bar using technique, be broken when serious, piling bar fracture restoration often requires to use largely
The equipments auxiliary such as large-scale lifting machinery and jack, be just able to achieve the movement of piling bar, but mobile distance and position is all
It is not easily controlled, because large-scale boom hoisting needs the operator of lifting appliance mobile piling bar, piling bar under the commander of personnel
In the state sling, it itself is also easy to happen shaking.Therefore it needs a kind of device to undertake the weight of piling bar and rotation is provided to hold
Carry power, moreover it is possible to move left and right adjustment when realizing piling bar cutting adjustment curvature；It also needs to solve piling bar to turn in maintenance
Dynamic problem.
Utility model content
The utility model provides a kind of dredger steel pile maintenance rotation for the piling bar maintenance peculiar to vessel that solves the problems, such as to dredge
Device.
The technical solution that the utility model solves above-mentioned technical problem is as follows: a kind of dredger steel pile maintenance rotation dress
It sets, is characterized in that, including pedestal, be mounted on the fixed idler whell and shifting roller at both ends above pedestal, fixed idler whell is logical
It crosses bracket to fix on the base, the frame bottom of shifting roller is equipped with sliding block, the cunning of sliding block inserting on the base by bolt
In road, the stent outer mounting and adjusting hydraulic cylinder of shifting roller, adjustment hydraulic cylinder is fixed on the hydraulic cylinder of pedestal upper surface setting
In mounting base；Motor mounting plate is fixedly mounted in the side of the axis of fixed idler whell, the variable-frequency motor for being equipped with cycloid speed reducer is solid
It is scheduled on motor mounting plate, the output shaft of cycloid tachogenerator is fixedly connected with the axis of fixed idler whell.
Further, supporting block is provided on the outside of the lower section of the hydraulic cylinder mounting base and pedestal.
The effect of the utility model is: piling bar peculiar to vessel of dredging is being tieed up because volume and weight is all very huge
During repairing, the device of support is needed, the rotating device of the application just plays the role of support, simultaneously as dredger
Centainly rotation or the displacement of transverse direction are needed in maintenance with piling bar, therefore is provided with fixed idler whell and movement on rotating device
Runner, runner alleviate the frictional force between piling bar and support device when piling bar needs to roll, and keep rotation more square
Just, while in mobile device side adjustment hydraulic cylinder is set, adjusts the spacing between adjustable two idler wheels of hydraulic cylinder, not
Mobile hydraulic cylinder provides support force.In maintenance, it is also desirable to piling bar roll, therefore install and become in the side of fixed idler whell
Frequency motor is rotated with variable-frequency motor come the drive fixed idler whell of active, will under the action of the frictional force of piling bar at this time
It rolls.This device assumes responsibility for the weight of piling bar and provides rotation bearing capacity.Also achieve piling bar cutting adjustment curvature
When move left and right the function of adjustment.
Fixed idler whell generally uses the driving wheel of diameter 450mm, shifting roller can be adjusted according to different piling bar diameters away from
From relative to reduction rotation, shearing force, driving rod idler wheel outfit 3KW variable-frequency motor and 731:1 cycloid speed reducer (are generally put at present
Line pin gear case), gear-box and wheel axis connection.The horizontal intermediate direction installation 50T* stroke 300mm adjustment of transverse shifting wheel is hydraulic
One, cylinder (pushing tow hydraulic cylinder).
Detailed description of the invention
Fig. 1 is a kind of dredger steel pile maintenance rotating device schematic perspective view of the utility model；
Fig. 2 is the schematic diagram of internal structure of Fig. 1.
Appended drawing reference record is as follows: 1- pedestal, 1.1- slideway, 2- fixed idler whell, 3- shifting roller, and 4- adjusts hydraulic cylinder,
5- supporting block, 6- bolt, 7- sliding block, 8- cycloid speed reducer, 9- motor mounting plate, 10- variable-frequency motor.
Specific embodiment
The principles of the present invention and feature are described below in conjunction with attached drawing, example is served only for explaining that this is practical
It is novel, it is not intended to limit the scope of the utility model.
Rotating device (referring to Fig. 1 and Fig. 2) is used in a kind of maintenance of dredger steel pile, including pedestal 1, is mounted on 1 top of pedestal
The fixed idler whell 2 and shifting roller 3 at both ends, fixed idler whell 2 are fixed by the bracket on pedestal 1, the frame bottom of shifting roller 3
Sliding block 7 is installed by bolt 6, sliding block 7 is inserted into the slideway 1.1 on pedestal 1, and the stent outer of shifting roller 3, which is installed, to be adjusted
Whole hydraulic cylinder 4, adjustment hydraulic cylinder 4 are fixed in the hydraulic cylinder mounting base of 1 upper surface of pedestal setting；In the axis of fixed idler whell 2
Motor mounting plate 9 is fixedly mounted in side, and the variable-frequency motor 10 for being equipped with cycloid speed reducer 8 is fixed on motor mounting plate 9, cycloid
The output shaft of tachogenerator 8 is fixedly connected with the axis of fixed idler whell 2.
Further, the lower section of the hydraulic cylinder mounting base and the outside of pedestal 1 are provided with supporting block 5.
When use, piling bar is placed between fixed idler whell and shifting roller on the base, when needed, is passed through
The collapsing length of adjustment hydraulic cylinder output end is adjusted to adjust shifting roller position on the base, realizes shifting roller and fixed rolling
Take turns the support to piling bar.When needing to be rolled piling bar, starts variable-frequency motor and fixed idler whell is driven to be rotated, steel
Stake will be rotated therewith.
The above is only the preferred embodiment of the present invention, is not intended to limit the utility model, all practical at this
