Abstract
The utility model discloses an inclined reciprocating grate supporting running roller device, every grade of grate is provided with 4 sets of running roller devices at least and supports, the running roller device comprises running roller bracket, running roller support, running roller and running roller support rail, and welding installation has the running roller bracket on boiler body's the inner wall, has the running roller support through the screw fastening on the running roller bracket, and the running roller supports with the axle through its inside bearing and installs on the running roller support, running roller support rail install the below at inclined reciprocating grate frame. This technical scheme simple structure, the practicality is strong, it is big to bear the load, grate movement resistance is little, move reliable and stable, long service life.
Description
Technical field:
The utility model relates to a kind of reciprocal grate backing roll wheel apparatus, is specially adapted to burn on biomass boiler use.
Background technology:
Reciprocal grate on current burning biomass boiler, every grade of fire grate on fire grate is supported on boiler body by 4 cover support steel balls and scroll-up/down rail set, and this device functional reliability in boiler operatiopn is poor.When fire grate moves back and forth, 4 cover steel ball bracing or strutting arrangements bear load and differ, and its roller track adheres to ashes foreign material again unavoidably, supporting steel club frequently occurs that rolling is obstructed, so that mobile dislocation, to dead-centre position, track termination, even drops out track, cause supporting fire grate and move back and forth disabler.
Summary of the invention:
Task of the present utility model proposes one to bear load greatly, and the fire grate resistance of motion is little, reliable a kind of reciprocal grate support roller device.
Task of the present utility model completes like this, a kind of reciprocal grate supporting roller wheel device, it is characterized in that: every grade of fire grate is at least provided with 4 cover roller apparatus and supports, described roller apparatus is made up of running roller bracket, running roller bearing, running roller and running roller supporting track, the inwall of boiler body is installed by welding with running roller bracket, running roller bracket there is running roller bearing by screw fastening, running roller is supported by the bearing of its inside and axle and is arranged on running roller bearing, and described running roller supporting track is arranged on the below of reciprocating furnace framed bent.Described running roller is provided with limited step.
The utility model has following effect: the technical program structure is simple, practical, and bear load large, the fire grate resistance of motion is little, stable and reliable operation, long service life.
Accompanying drawing illustrates:
Fig. 1 is the horizontal section structure schematic diagram of support running roller of the present utility model; Fig. 2 supports running roller vertical structure schematic diagram.
Drawing illustrates: 1, roller bracket, 2, running roller bearing, 3, running roller, 4, running roller supporting track, 5, reciprocating furnace framed bent, 6, boiler body, 7, screw.
Detailed description of the invention:
The technical program solves fire grate to move back and forth bracing or strutting arrangement frequent failure, the defect of functional reliability difference.Specific embodiment as depicted in figs. 1 and 2, every grade of fire grate arranges 4 cover roller apparatus and supports, described roller apparatus is made up of running roller bracket 1, running roller bearing 2, running roller 3 and running roller supporting track 4, the inwall of boiler body 6 is installed by welding with running roller bracket 1, running roller bracket is fastened with running roller bearing 2 by screw 7, running roller 3 is supported by the bearing of its inside and axle and is arranged on running roller bearing 2, and described running roller supporting track 4 is arranged on the below of reciprocating furnace framed bent 5.Described running roller is provided with limited step, during to ensure that fire grate moves back and forth, lateral attitude is placed in the middle all the time, running roller and running roller bearing and running roller tray chamber adopt screw attachment, so that detachable maintaining, running roller supports reciprocating furnace framed bent by running roller supporting track, fire grate is moved back and forth and is in rolling friction state all the time, thus ensure that fire grate stable and reliable operation, bear load large, extend the service life of fire grate.
