Abstract
The invention belongs to the technical field of annular cooler equipment, and in particular relates to an annular cooler reset roller device which is characterized by comprising a support beam and a reset roller component, wherein the support beam is arranged at the lower part of a discharge spout of an annular cooler discharge area in the radial direction of an annular cooler rack; the two ends of the support beam are respectively connected with the annular cooler rack; the reset roller component is fixed on the support beam and is positioned in front of a downloaded vertical trolley in the trolley return direction. The annular cooler reset roller device is simple in structure and convenient to manufacture and install, as the reset roller device is no longer connected with inner and outer side plates of the discharge spout of the annular cooler discharge area but independently supported on the rack of the annular cooler, the problems that a reset roller is slanted and the surface of the reset roller is severely abraded due to the fact that the rigidity of the side plates of the annular cooler is not sufficient are solved, and the reset roller device is simple and convenient to operate and maintain, and is long in service life.
Description
Technical field
The invention belongs to central cooler equipment technical field, especially relate to a kind of annular cooler reset roller device.
Background technology
The reset roller of central cooler is arranged in the below of unloading place of circular cooler hopper and chassis, is the servicing unit of the chassis after making discharging by vertically-arranged state progressively recovery level, so that chassis can continue to accept material.The operation principle of existing annular cooler reset roller is the chassis after discharging, under the driving of central cooler drive unit, by chassis axle along with slewing frame is around the revolution of the central cooler centre of gyration, in the process of advancing, chassis completes discharging action by gravity eccentricity and exists side by side in erectility.Along with moving ahead of chassis, a peripheral edge of the bottom of chassis, contact with the roll surface of running roller, make the surface of chassis from uprightly progressively becoming inclination, and along with moving ahead of chassis progressively diminishes with the angle of inclination of horizontal plane, until the running roller be positioned in chassis shaft end roller arm contacts with Orbit unloaded skip, and make trolley surface progressively recovery level, continue to accept material, repeat next cool cycles.In the manufacture and equipment operation process of central cooler, because reset roll shaft will be fixed on the inside and outside side plate of blowpit by bearing block.Along with the increase of circular cooler trolley width, the length of reset roll shaft also can lengthen.Rigidity by structure restriction side plate is not fine, the axiality of two side shaft holders also not easily ensures, although employ spherical bearing, axle itself gets into smooth, and center line also there will be inclination to a certain degree, and reset roller roll surface also can be tilted, the reset of chassis can be very unstable, the wearing and tearing of reset roller roll surface simultaneously also can be uneven, and the stress of two side bearings is very undesirable, has extra additional force to produce.The life-span of bearing and reset roller also can reduce.
Summary of the invention
The object of this invention is to provide a kind of structure simple, manufacture, installation, maintenance are convenient, the annular cooler reset roller device of long service life.
The object of the invention is to be realized by following technical proposals:
Annular cooler reset roller device of the present invention, it is characterized in that comprising the blowpit bottom that is located at central cooler discharge zone along central cooler frame in radial direction and the brace summer that is connected with central cooler frame respectively of two ends, be fixed on described brace summer, and the reset roll assembly in upright chassis front be positioned at discharging on chassis gyratory directions after.
Described reset roll assembly comprises the support be fixedly connected with described brace summer by bolt assembly, be fixed on the axle on this support, by the running roller that socket bearing is on which axle connected with described central axis, be located at the black box of these running roller both sides, be located at the axial location snap ring in described axle, if anti-central axis clamp on the bracket.
Described black box comprises the sealing gasket, gland and the labyrinth seal gland that are located at described axle both sides.
The cross section of described brace summer is H-shaped formula.
Described bearing is sliding bearing.
Described bearing is rolling bearing.
Advantage of the present invention:
Structure of the present invention is simple, making and installation is convenient, reset roller arrangement is no longer connected with the inside and outside side plate of the blowpit of central cooler discharge zone, but independent support is in the frame of central cooler, avoid because inadequate the caused reset roller of central cooler side plate rigidity tilts, the problem that reset roller roll surface wearing is serious.The operation maintenance of this reset roller arrangement is simple and convenient, long service life.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention.
Fig. 2 is the structural representation of reset roll assembly of the present invention.
Detailed description of the invention
The specific embodiment of the present invention is further illustrated below in conjunction with accompanying drawing.
As illustrated in fig. 1 and 2, annular cooler reset roller device of the present invention, it is characterized in that comprising and be located at the blowpit bottom of central cooler discharge zone and the brace summer 1 that is connected with central cooler frame 3 respectively of two ends along central cooler frame 3 radial direction, be fixed on described brace summer 1, and the reset roll assembly 2 in upright chassis 4 front be positioned at discharging on chassis 4 gyratory directions after.
Described reset roll assembly 2 comprises the support 5 be fixedly connected with described brace summer 1 by bolt assembly, be fixed on the axle 6 on this support 5, by the running roller 8 that the bearing 7 be socketed in this axle 6 is rotationally connected with described axle 6, be located at the black box of these running roller 8 both sides, be located at the axial location snap ring 12 in described axle 6, be located at the anti-central axis clamp 13 on described support 5, the end cross-sectional of described axle 6 is lower arc, a long limit of arc planar section and described anti-central axis clamp 13 is abutted against, for preventing the rotation of axle 6.
Described black box comprises the sealing gasket 9, gland 10 and the labyrinth seal gland 11 that are located at described axle 6 both sides.
The cross section of brace summer 1 can be various forms, and the cross section of such as brace summer 1 is H-shaped formula.
Described bearing 7 can be sliding bearing, also can be rolling bearing.
Structure of the present invention is simple, making and installation is convenient, reset roller arrangement is no longer connected with the inside and outside side plate of the blowpit of central cooler discharge zone, but independent support is in the frame 3 of central cooler, avoid due to central cooler side plate because inadequate the caused reset roller of rigidity tilts, the problem that reset roller roll surface wearing is serious.The operation maintenance of this reset roller arrangement is simple and convenient, long service life.
