Wherein, one end of the front section 11 of the rear cone is welded with the raceway assembly 2, and the other end is welded with the middle section 20. One end of the rear cone rear section 12 is welded with the raceway assembly 2, and the other end is provided with an opening for concrete to enter and exit.
Referring to fig. 3 to 5, the track assembly 2 includes a track frame 22 and a track 23, both of which are annular, the track 23 being mounted on the track frame 22.
The track frame 22 includes a connecting portion 221 and a mounting portion 222, and the connecting portion 221 and the mounting portion 222 are integrally formed and are both annular.
An annular mounting groove 224 is opened outward in the connecting portion 221, and the raceway 23 is detachably mounted in the mounting groove 224. Specifically, in the present embodiment, the mounting groove 224 is an annular U-shaped groove.
The middle part of the inner periphery of the mounting part 222 extends inwards to the cylinder body to form a convex ring 223, and two side surfaces of the convex ring 223 are respectively welded with the rear cone front section 11 and the rear cone rear section 12. Meanwhile, the inner peripheral surface of the mounting portion 222 is tapered, and the taper of the mounting portion is consistent with the taper of the rear cone front section 11 and the rear cone rear section 12, that is, the inner peripheral surface of the raceway frame 22 is in contact fit with the outer peripheral surfaces of the rear cone front section 11 and the rear cone rear section 12, so that the mounting portion 222 is matched and welded on the rear cone section 10.
Because the convex ring 223 is arranged in the middle of the inner circumferential surface of the mounting portion 222, the rear cone front section 11 and the rear cone rear section 12 can be conveniently inserted into two sides of the raceway frame 22 respectively and are in contact connection with the convex ring 223, the requirements on the positioning of the raceway frame 22 and the rolling precision of the mixing drum 1 are reduced, and the welding of the raceway frame 22 is more convenient. The taper of the inner circumferential surface of the mounting portion 222 is consistent with the tapers of the rear cone front section 11 and the rear cone rear section 12, so that the inner circumferential surface of the mounting portion 222 can be respectively attached to the rear cone front section 11 and the rear cone rear section 12 more tightly, and the welding quality between the raceway frame 22 and the rear cone section 10 is improved.
Meanwhile, as can be seen from the above connection method, the front side surface of the track frame 22 located outside the rear cone front section 11 is welded to the outer peripheral surface of the rear cone front section 11 (as indicated by 51 in the drawing), and the front side surface of the protruding ring 223 is also welded to the inner peripheral surface of the rear cone front section 11 (as indicated by 52 in the drawing). Meanwhile, the rear side surface of the track frame 22 located outside the rear cone rear section 12 is welded to the outer peripheral surface of the rear cone rear section 12 (as indicated by 53 in the drawing), and the rear side surface of the protruding ring 223 is also welded to the inner peripheral surface of the rear cone rear section 12 (as indicated by 54 in the drawing). Namely, two welding seams are arranged on two sides of the raceway frame 22 and are respectively positioned on two sides of the rear cone section 10, so that the strength of the welding seams is greatly enhanced, and the problem of welding seam cracking is favorably solved.
It can be understood that, in one embodiment of the present invention, the horizontal sectional area of the mounting portion 222 is gradually reduced in the direction away from the rear cone section 11, so as to reduce the volume of the track frame 22 and reduce the self weight thereof on the premise of ensuring the structural strength.
Referring to fig. 4 and 6, the raceway 23 is formed by splicing a plurality of curved raceway segments 231, and the raceway segments 231 include: and an inner race portion 2311 and an outer race portion 2312 which are integrally formed, wherein the inner race portion 2311 is caught in the mounting groove 224, and the outer race portion 2312 is located outside the outer circumferential surface of the connecting portion 221 of the race frame 22. The width of the inner track portion 2311 is substantially equal to the width of the mounting groove 224, the width of the outer track portion 2312 is wider than the width of the inner track portion 2311, and both sides thereof protrude from the inner track portion 2311, so that the axial cross section of the track segment 231 is T-shaped.
In the working process, the rolling path 23 supports the whole mixing drum 1 to roll on the riding wheel 4, so that the rolling path 23 is easier to wear relative to the mixing drum 1, and therefore, the rolling path 23 can be made of wear-resistant materials, such as steel materials, wear-resistant metal materials and the like. In the present embodiment, the raceway 23 is formed by splicing a plurality of arc-shaped raceway segments, and is detachably mounted on the raceway frame 22, and when the raceway 23 is damaged or seriously worn due to abnormal collision, the corresponding raceway segments can be removed according to actual needs, and a new raceway segment is replaced. Because the whole mixing drum 1 and even the whole raceway 23 do not need to be replaced, the maintenance efficiency of the raceway 23 is improved, the labor intensity of maintenance workers is reduced, and the maintenance cost of the raceway 23 can be greatly reduced. Meanwhile, in the present embodiment, the width of the outer track portion 2312 is wider than that of the inner track portion 2311, so that the section of the track section is T-shaped, that is, compared with the case where the width of the outer track portion 2312 is the same as that of the inner track portion 2311 and the track with a rectangular section has a larger contact area with the riding wheel 4 and is subjected to smaller pressure, so that the track is more wear-resistant and has a longer service life.
The inner race 2311 and the connecting part 221 of the race 22 are respectively and correspondingly provided with through holes 203 penetrating through the inner race 23 and the connecting part 221 of the race 22, and the fastener 21 can enable the inner race 232 to be detachably and tightly mounted in the mounting groove 224 through the through holes 203. It is understood that the fastening member 21 may be a detachable fastening member such as a bolt, a pin, a key, etc., and in this embodiment, is a fastening bolt. The fastening bolt is preferably fixed, but in other embodiments, other detachable fixing methods known to those skilled in the art may be adopted.
As described above, the horizontal sectional area of the mounting portion 222 gradually decreases in a direction gradually away from the rear tapered section 11. Besides, the volume and the dead weight of the raceway frame 22 are reduced on the premise of ensuring the structural strength, the length of the fastener is reduced, and the raceway 23 is more convenient to assemble and disassemble.
As further shown in fig. 4, the two sides of the mounting groove 224 are also respectively provided with a gasket 24, the gasket 24 is also correspondingly provided with a circular hole (not shown) for the fastener 21 to pass through, the distance between the gaskets 24 on the two sides of the mounting groove 224 is smaller than the width of the inner rolling path 2311, so that the inner rolling path 2311 is in interference fit with the mounting groove 224, the inner rolling path 2311 is attached to the mounting groove 224 more tightly, the inner rolling path 2311 is ensured to be firmly clamped in the mounting groove 224, and the phenomenon that the rolling path 23 is axially displaced on the mixing drum 1 due to looseness in the operation process of the mixer truck is avoided, and noise generated in the operation process of rolling the components is reduced. Since the gasket 24 makes the inner race 2311 and the mounting groove 224 have an interference fit, the inner race 2311 is not easily mounted into the mounting groove 224 during the mounting process, and a guide groove (not shown) surrounding the barrel of the mixer drum 1 may be formed on the outward side of the gasket 24 and the track frame 22 to guide the inner race 2311 into the mounting groove 224.
While the present disclosure has been described with reference to several exemplary embodiments, it is understood that the terminology used is intended to be in the nature of words of description and illustration, rather than of limitation. As the present disclosure may be embodied in several forms without departing from the spirit or essential characteristics thereof, it should also be understood that the above-described embodiments are not limited by any of the details of the foregoing description, but rather should be construed broadly within its spirit and scope as defined in the appended claims, and therefore all changes and modifications that fall within the meets and bounds of the claims, or equivalences of such meets and bounds are therefore intended to be embraced by the appended claims.
