Abstract
The utility model relates to an important part of a coal-mine tunnel road-header, in particular to a star-wheel driving device for a shoveling plate part of a road-header. Aiming at solving the problem that the cutting arm easily collides with the star-wheel of the existing road-header when the road-header is working, the utility model can greatly improve the tunneling efficiency and reduce the labor intensity of the operator. A rotary support bearing is arranged between the star wheel and a flange disc connected with a hydraulic motor. With simple structure, the device adopts the rotary support bearing to substitute for a taper roller bearing to reduce the height of the star wheel and improve the stability.
Description
Technical field
The utility model relates to the vitals of coal mine roadway development machine, is specially a kind of star-wheel-drive device that is used for development machine shovel board portion.
Background technology
At present, when excavation operation, cutterhead needs up and down back and forth cut, and very big thrust is arranged with development machine in the colliery, and existing star-wheel-drive device structure weak point is that star-wheel is higher, the easy and star-wheel collision of cutting arm.So, be starved of a kind of star-wheel-drive device that is difficult for breaking, improve the operating efficiency of driving, reduce operator's labour intensity.
The utility model content
The star-wheel-drive device that provides a kind of height lower is provided the purpose of this utility model, solve the problem that cutting arm is easy and star-wheel collides when having the development machine excavation operation now, this star-wheel device can increase substantially headwork efficient, greatly reduces operator's working strength.
The technical solution of the utility model is:
Be provided with pivoting support bearing between a kind of star-wheel-drive device, star-wheel and the flange that is connected hydraulic motor.
The beneficial effects of the utility model are:
The utility model development machine star-wheel-drive device, replaced two taper roll bearings with a pivoting support bearing, reduced the height of star-wheel, cutting arm and star-wheel collision when avoiding the development machine operation, prevent that the tunneling machine cutting arm from breaking star-wheel-drive device, improve reliability.
Description of drawings
Fig. 1 is the structure chart of the utility model drive unit.
Fig. 2 is the vertical view of the utility model drive unit.
Among the figure, 1 star-wheel; 2 pivoting support bearings; 3 hydraulic motors; 4 flange; 5 floating seals; 6 sealing rings.
The specific embodiment
Shown in Fig. 1-2, the utility model is a development machine shovel board star-wheel-drive device, between star-wheel 1 and the flange 4 that is connected hydraulic motor 3 pivoting support bearing 2 is arranged, hydraulic motor 3 is installed on the flange 4, drives star-wheel 1 by pivoting support bearing 2, seals with floating seal 5 and sealing ring 6 between star-wheel 1 and the flange 4.
The course of work of the present utility model is as follows:
(1) hydraulic motor 3 rotations drive star-wheel 1 by pivoting support bearing 2 and rotate.
(2) hydraulic motor 3 stops, and drives star-wheel 1 by pivoting support bearing 2 and stops operating.
Claims (1)
1. star-wheel-drive device is characterized in that: be provided with pivoting support bearing between star-wheel and the flange that is connected hydraulic motor.
