Detailed Description
The following description of the embodiments of the present invention will be made clearly and completely with reference to the accompanying drawings, in which it is apparent that the embodiments described are only some embodiments of the present invention, but not all embodiments. All other embodiments, which can be made by those skilled in the art based on the embodiments of the invention without making any inventive effort, are intended to be within the scope of the invention.
Referring to fig. 1 to 5, there is a bucket side edge protection mechanism, wherein wing plates are provided on both sides of a side edge sheath 1, the side edge sheath 1 is sleeved on a bucket side edge 2, and the wing plates of the side edge sheath 1 are respectively arranged on both sides of the bucket side edge 2. Two bosses 12 are arranged at the position between the two wing plates at the bottom of the side edge sheath 1, the bosses 12 and the side edge sheath 1 are integrally formed, and when the side edge sheath 1 is sleeved on the side edge 2 of the bucket, the bosses 12 are abutted against the end face 22 of the side edge 2 of the bucket. During bucket construction, the bucket side edge 2 is often impacted by materials, and the two bosses 12 in the side edge sheath 1 are in installation fit with the bucket side edge end face 22, so that only part of the inner end face of the side edge sheath 1 is in contact with the bucket side edge end face 22, toughness of the side edge sheath 1 can be increased, and impact on the bucket side edge 2 and the pin 4 can be reduced.
The wing plate of the side edge sheath 1 and the side edge 2 of the bucket are provided with a plurality of opposite mounting through holes, so that the side edge sheath 1 is prevented from rotating due to uneven stress. In this embodiment, the number of the through holes I11 on the wing plate of the side edge sheath 1 is preferably 2, and the through holes II 21 on the side edge 2 of the bucket. A pin 4 is arranged in the mounting through holes of the wing plate of the side edge sheath 1 and the side edge 2 of the bucket. The inner end of the upper through hole I11 of the wing plate of the side blade sheath 1 is provided with a counter bore 13, the depth of the counter bore 13 is equal to the thickness of the clamp spring 5, and the outer ring of the clamp spring 5 is embedded in the counter bore 13 at the inner end of the mounting through hole of the wing plate of the side blade sheath 1. The distance between two wing plates of the side edge sheath 1 is consistent with the thickness of the side edge 2 of the bucket, and the clamp spring 5 can be completely embedded into the counter bore 13, so that the side edge sheath 1 is tightly matched with the side edge 2 of the bucket. The inner diameter of the counter bore 13 is slightly larger than the outer diameter of the clamp spring 5, so that the clamp spring 5 can be spread, and the pin 4 is convenient to install.
And in combination with the figures 6 to 8, the two ends of the pin 4 do not exceed the wing plates of the side edge sheath 1, so that the impact and abrasion of materials on the pin 4 during construction are reduced. Annular grooves 41 are formed in the two ends of the pin 4, and the inner rings of the clamp springs 5 are embedded in the annular grooves 41 in the two ends of the pin 4. The pin 4 is provided with chamfers 42 at both ends and inside the annular groove 41 of the pin 4, and the pin 4 can be mounted and dismounted from any side of the side edge sheath 1 by the chamfers 42.
In addition, the wing plate of the side edge sheath 1 is provided with a U-shaped groove 14, and the U-shaped groove 14 is positioned between 2 through holes I11 on the wing plate of the side edge sheath 1. The size of the limiting block 3 is consistent with that of the U-shaped groove 14, the limiting block 3 is embedded in the U-shaped groove 14, one side of the limiting block 3 is welded with the side edge 2 of the bucket, the other three sides of the limiting block 3 are in close fit with the side edge sheath 1, the influence of the insecurity in installation of the side edge sheath 1 caused by the machining error of the side edge 2 of the bucket is overcome, the reliability of connection is enhanced, and the impact on the pin 4 is reduced. Because the side edge sheath 1 is a vulnerable part and is frequently replaced, the design of the U-shaped groove 14 also reduces the production cost of the side edge sheath 1 and the use cost of the bucket.
Before the side edge sheath 1 and the bucket side edge 2 are mutually installed, the clamp spring 5 is installed in the counter bore 13 in advance, and then the upper through hole I11 of the side edge sheath is aligned with the side edge through hole II 21 of the bucket;
then the pin 4 is inserted into the snap spring 5 from any end;
knocking the pin 4 by using tools such as a hammer, so that the end part of the pin 4 is chamfered to prop open the first clamp spring 5, and smoothly passing the front end of the pin 4 through the first clamp spring 5 by using a chamfer 42 on the pin 4;
continuously knocking the pin 4 to enable the front end of the pin 4 to enter the second clamping spring 5, and enabling the two clamping springs 5 to be clamped in the annular groove 41 of the pin 4;
the limiting block 3 is welded on site, one side of the limiting block 3 is welded with the side edge 2 of the bucket, and the other three sides of the limiting block 3 are tightly matched with the side edge sheath 1;
when the side edge sheath 1 is dismantled, only the pin 4 needs to be smashed out from any one end, and the limiting block 3 can be used continuously, so that the replacement is convenient.
In this embodiment, the whole bucket side edge protection mechanism adopts bilateral symmetry structure, and the connection is more firm, equalizes pin 4 both ends atress simultaneously, avoids stress concentration. This bucket side edge protection machanism has avoided using the not hard up problem of side edge sheath that the bolt installation caused for the installation of side edge sheath is dismantled more conveniently, has improved the operating efficiency, has reduced scraper bowl use cost.
