Abstract
A round top beam cover of a six-valve grab bucket includes round sideboards, an integral upper panel on the surfaces of the sideboards, an circular lower panel, cross beams, shaft hole frames and a lifting hole frame, wherein the lower panel is positioned on the lower edges of the sideboards, the cross beams are positioned within the sideboards, the shaft hole frames are positioned outside the sideboards of the cross beams, and the lifting hole frame is positioned on the upper panel. The three cross beams which are disposed in the diameter direction of the round sideboards equally occupy a 360degree circle, one cross beam is a thickened cross beam, and a shaft hole is arranged at the middle of the thickened cross beam. The structure of the round top beam cover is utilized in bulk six-valve grab buckets, namely the technique of improving the original hexagonal top beam cover into the round top beam cover, thereby avoiding the occasion of stress concentration, obviously improving the force upon the sideboards, and preventing sideboard cracking. During application for more than half a year, the round top beam cover is normally operated constantly.
Description
Technical field
The utility model belongs to the six lobes grab buckets parts of harbor equipment, designs a kind of six lobes circular upper beam cap of grabbing bucket especially.
Background technology
The aperature of angle situation of enclosing of six square upper beam cap coaming plates takes place in four multiplying powers, the six lobes grab bucket of existing harbor equipment often in long-term frequent the use, still enclose aperature of angle problem after repeatedly reinforcing repair welding again and again.
Summary of the invention
The purpose of this utility model provides one the six lobe circular upper beam cap of grabbing bucket, and improves the coaming plate bending angle cracking problem of six square upper beam caps.
Particular content of the present utility model is:
A kind of six lobes circular upper beam cap of grabbing bucket, it is characterized in that: the coaming plate of a circle, upper surface at coaming plate has the single-piece top panel, the lower faceplate that one loop is arranged in the coaming plate lower edge, in the coaming plate of circle, crossbeam is arranged, the axis hole frame is arranged outside the coaming plate of crossbeam, and there is the lifting hole(eyelet) frame in the central authorities above the plate in the above.
Have crossbeam to have three in the coaming plate of circle, every crossbeam all is located at the diametric(al) of circular coaming plate, and three crossbeam line of centerss are divided equally 360 degree circles, and wherein a crossbeam is the thickness deep beam, in the centre of thickness deep beam axis hole is arranged.
The utility model effect is:
In bulk goods six lobes grab buckets, adopt the structure of " circular upper beam cap ", be about to the new process that former hexagon upper beam cap changes circular upper beam cap into, avoided occurring the situation of stress concentration, make coaming plate stressed be improved significantly.Stopped coaming plate cracking situation.Since using more than half a year, any abnormal condition did not appear in circular upper beam cap.

The specific embodiment
The circular upper beam cap of grabbing bucket of a kind of six lobes as shown in Figure 1, 2, the coaming plate 1 of a circle, at coaming plate single-piece top panel 2 arranged, the lower faceplate 3 that one loop is arranged in the coaming plate lower edge, crossbeam 4 is arranged in the coaming plate of circle, axis hole frame 5 is arranged outside the coaming plate of crossbeam, and there is lifting hole(eyelet) frame 6 in the central authorities above the plate in the above.
Have crossbeam to have three in the coaming plate of circle, every crossbeam all is located at the diametric(al) of circular coaming plate, and three crossbeam line of centerss are divided equally 360 degree circles, and wherein a crossbeam is a thickness deep beam 7, in the centre of thickness deep beam axis hole 8 is arranged.
The more former hexagon upper beam of novel circular upper beam cap cap all less than too big variation, also is more or less the same on weight aspect steel plate thickness, material; Make circular upper beam cap and still select the Q345 steel plate for use, this steel plate has good comprehensive mechanical properties, and plasticity and welding performance are good, and dynamic ductility is better.When this steel plate of welding, select J506 welding rod and JQ.MG50-6 welding wire for use.
The top panel diameter of former hexagon upper beam cap is slightly less than the coaming plate diameter, and welding manner is a fillet weld; The top panel diameter of new circular upper beam cap is greater than the coaming plate diameter, and coaming plate welds with its top panel after beating double groove;
Below coaming plate, be welded into lower faceplate, make the cross sectional shape of coaming plate become amended " worker " word, the cross section geometric character of coaming plate is improved greatly by original " 1 " word with a doughnut-shaped steel plate.
