Abstract
The utility model relates to a scrapping plate guide wheel device for a scrapping plate conveyor. The device comprises a guide wheel, bearings, a pin shaft, a nut, a gasket and a bracket, wherein the guide wheel is fixed on the bracket through the bearings, the pin shaft, the nut and the gasket, a dustproof lug boss is arranged at the clearance between the guide wheel and a machine frame and fixed on the bracket, and the end surface size of the dustproof lug boss is determined in such a way that at least part of a bearing outer ring can be sealed. The additional arrangement of the dustproof lug boss ensures that the dustproof property of the guide wheel device is greatly improved, and the guide wheel bearings cannot be stuck or damaged, thereby reducing the maintenance cost and improving the production efficiency of the scrapping plate conveyor.
Description
Technical field
The utility model relates to a kind of slat conveyer scraper plate guide wheel device.
Background technology
Slat conveyer is the major equipment that materials such as sandstone, coal are carried in the mine.The guide wheel device by the centre cooperated with guide groove and led scraper plate when operation, this guide wheel device is made up of guide wheel, bearing, bearing pin, nut, pad and support usually, support is fixed in the middle of the scraper plate, and guide wheel passes through bearing, bearing pin, nut and spacers on support.Because bearing adopts needle bearing usually, gap between the bearing inner and outer ring is big, and the gap of the about 2cm of a segment length is arranged between guide wheel and the support, sandstone and dust are entered in the bearing by the gap between guide wheel and the support easily, cause bearing needle to come off and stuck, cause whole scraper plate travel line to stop, not only influenced production efficiency, and the maintenance cost height.
Summary of the invention
The purpose of this utility model is at the deficiencies in the prior art part, and a kind of slat conveyer scraper plate guide wheel device is provided, and has good dustproof effect, and non-damageable advantage can reduce maintenance cost, improves the production efficiency of slat conveyer.
For achieving the above object, the utility model has adopted following technical scheme: it comprises guide wheel, bearing, bearing pin, nut, pad and support, guide wheel passes through bearing, bearing pin, nut and spacers on support, gap location between guide wheel and the frame is provided with dustproof boss, described dustproof boss is fixed on the support, the through hole that has the supply and marketing axle to pass through in the middle of the dustproof boss, dustproof raised head face size at least can the enclosure portion outside race.Because the end face of dustproof boss can detailed manufacture, dustproof boss can be reduced in several millimeters with gap between the bearing side, good dustproof effect, and sandstone and dust are difficult for entering in the bearing, and bearing can stuck or damage.
Preferred version of the present utility model is: described bearing is two single-row centripetal shield bearings that are set up in parallel.Gap between the Internal and external cycle of single-row centripetal shield bearing is little, and good dustproof effect is set up in parallel alternative needle bearing with two single-row centripetal shield bearings and can satisfies the scraper plate workload.Use two single-row centripetal shield bearings that are set up in parallel to also help the end float misalignment of subduing guide wheel simultaneously, reduce shearing force, can not be damaged by the protected key axle cap, prolong the service life of bearing pin the bearing pin cap.
As shown from the above technical solution, the utility model has improved the anti-dust performance of guide wheel device greatly by setting up dustproof boss, and the guide wheel bearing can be not stuck or be damaged, and can reduce maintenance cost, improves the production efficiency of slat conveyer.Select for use two single-row centripetal shield bearings that are set up in parallel to also help the end float misalignment of subduing guide wheel in addition, reduce shearing force, can not be damaged by the protected key axle cap, prolong the service life of bearing pin the bearing pin cap.
Description of drawings
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is the right elevation of Fig. 1.
The specific embodiment
As shown in Figure 1 and Figure 2, support 8 adds the welding steel plate by the channel-section steel two ends and constitutes, connect with bearing pin 4 by two single-row centripetal shield bearings 5 that are set up in parallel in the bearing groove of guide wheel 3 inboards, bearing pin 4 other ends are fixed on the support 8 by pad 2 and nut 1, and the spring cotter 7 spacing to nut 1 is equipped with in bearing pin 4 ends.Gap location between guide wheel 3 and the support 8 is provided with cylindrical dustproof boss 6, the through hole that has supply and marketing axle 4 to pass through in the middle of the dustproof boss 6, dustproof boss 6 is fixed by welding on the support 8, the external diameter of dustproof boss 6 is greater than the internal diameter of bearing 5 outer rings, make that dustproof boss 6 end face sizes at least can enclosure portion bearing 5 outer rings, make the circular groove between bearing 5 Internal and external cycles be blocked by dustproof boss 6, sandstone and dust can not directly be entered in the bearing 5 by the circular groove between the bearing enclose.
