FIG. 3 is a cross-sectional view A-A of FIG. 2;
FIG. 4 is a schematic diagram of the present invention;
wherein: 1 wheel fill drive bearing frame I, 2 wheel fill drive bearing frames II, 3 wheel fill drive shafts, 4 bearing early warning devices, 41 riding wheels, 42 riding wheel seats, 43 riding wheel shafts, 6 wheel fills, 7 steel beams, E is that the wheel fill drive shaft is in the normal position, F is that the wheel fill drive shaft is in the abnormal position.
The specific implementation mode is as follows:
example 1
As shown in fig. 1 to 3, the utility model relates to a mechanical device for detecting abnormal wear of bucket wheel machine wheel fill drive bearing frame, include: bearing early warning device 4, wheel fill drive shaft 3 installs on girder steel 7 through wheel fill drive bearing frame I1 and wheel fill drive bearing frame II2, and the both ends of wheel fill drive shaft 3 are connected with wheel fill 6 and drive arrangement respectively, wheel fill drive bearing frame II2 is located wheel fill 6 one side. The bearing early warning device 4 is fixed on the steel beam 7 and is positioned between the bucket driving bearing seat I1 and the bucket driving bearing seat II2 and below the bucket driving shaft 3, and preferably, the bearing early warning device 4 is arranged close to the bucket driving bearing seat II 2.
The bearing early warning device 4 comprises two riding wheels 41 and riding wheel seats 42, wherein the riding wheels 41 are equal in height and arranged in parallel, each riding wheel 41 is rotatably installed on the riding wheel seat 42 through a riding wheel shaft 43, in order to move and install, the riding wheel seat 42 is composed of two single riding wheel seats with the same structure and size, and the longitudinal sections of the single riding wheel seats are trapezoidal. The two riding wheels 41 are respectively positioned at two sides of the axis of the wheel bucket driving shaft 3, the outer wall of each riding wheel 41 is in clearance fit with the outer wall of the wheel bucket driving shaft 3, and the clearance distance is 1-3 mm.
The installation process comprises the following steps:
when the device is installed, the gap between the outer wall of each supporting wheel 41 and the outer wall of the wheel bucket driving shaft 3 is 3mm by measuring the height between the wheel bucket driving shaft 3 and the steel beam 7, the upper plane of each supporting wheel 41 and the wheel bucket driving shaft keep the same inclination, and the supporting wheel seat 42 is welded on the steel beam 7 after the position is adjusted.
The use process comprises the following steps:
when the bearings in the bucket driving bearing seat II2 are in a normal state, the outer wall of each idler 41 is in clearance fit with the outer wall of the bucket driving shaft 3, and the two idlers 41 do not rotate, as shown in a position E in fig. 4.
When the bearing in the wheel bucket driving bearing seat II2 is in an abnormal state (under abnormal stress or insufficient lubrication), because the damage of the bearing is generally that the retainer and the rolling element are damaged first, under the influence of the self gravity of the wheel bucket 6 and the stress of the excavated material, one side close to the wheel bucket 6 moves downwards, as shown in fig. 4, the position E is changed to the position F, the weight of the wheel bucket driving shaft 3 is pressed on the bearing early warning device 4, and after the bearing early warning device 4 is stressed, the wheel bucket driving shaft 3 is pressed on the two riding wheels 41. With the continuous rotation of the wheel bucket driving shaft 3, the two riding wheels 41 are influenced by the gravity of the wheel bucket driving shaft 3 and the reaction force generated by the materials dug in the wheel bucket 6, so that the whole weight is pressed on the two riding wheels 41, and the two riding wheels 41 are forced to synchronously rotate along with the wheel bucket driving shaft 3. Because of bearing early warning device 4 is close to II2 settings of wheel fill drive bearing frame, after the wheel fill drive shaft 3 takes place to rotate, the operation, the maintainer can utilize the highlight, whether the riding wheel 41 rotates from the outside observation, perhaps the operation personnel only need regularly inspect whether the riding wheel 41 rotates, can judge whether the bearing that is located wheel fill drive bearing frame I1 and wheel fill drive bearing frame II2 has abnormal wear or the damaged condition, the very first time notice maintainer inspection that targets in place, avoid the accident further to enlarge.
The above description is only the preferred embodiments of the present invention, and these embodiments are all based on the present invention, and the protection scope of the present invention is not limited thereto, and any changes or substitutions that can be easily conceived by those skilled in the art within the technical scope of the present invention should be covered by the protection scope of the present invention. Therefore, the protection scope of the present invention shall be subject to the protection scope of the claims.
