Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a fastening device for a heavy dump vehicle that is transported in two parts.

[Conventional technology]

Due to the wide width of heavy dump vehicles, they must be transported in two parts according to the Road Transport Act in Japan.Therefore, conventionally, the vehicles were assembled and divided by welding or fusing when moving. .

[Problem that the invention attempts to solve]

However, as mentioned above, welding and
For items that are assembled or divided by fusing,
Not only was it expected that the material would deteriorate in the welded and fused parts, but it also required a lot of time to assemble and separate, leading to problems with poor reliability and workability.

In view of the above points, it is an object of the present invention to provide a fastening device for a heavy dump vehicle that is easy to assemble and divide, and that can ensure sufficient strength after assembly.

[Means for solving problems]

The heavy dump vehicle fastening device of the present invention is formed so that the heavy dump vehicle can be divided along the axis at a position offset from the vehicle body axis, and the joints of the two divided vehicle structures are connected to each other. Each joint surface has an outward flange shape that overlaps, and each of these joint surfaces has holes drilled at multiple locations in the longitudinal direction having the same axis that coincides with the joining process, and one of the holes has a bolt attached to the shaft center. A centering member having a through hole and a tapered shape formed on the outer periphery of the tip portion is tightly fitted and fixed, and the other hole serves as a socket for the tapered portion of the centering member at the tip of the shaft center portion. A ring member having a widening opening is provided in a tight fit, and both vessel structures are joined by fastening and fixing the centering member and the ring member with bolts and nuts.

[Effect]

According to the present invention, since the flange-like joint surfaces provided at the respective joints of both the Vessel structures to be divided form the cut surfaces of the Vessel divided portions, it is possible to set the cut surfaces large, and the assembly Afterwards, sufficient strength of the joint can be ensured, and at the time of assembly, the joint can be easily aligned by the centering member and ring member fixed to both joint surfaces, respectively.

〔Example〕

Hereinafter, one embodiment of the present invention will be described based on the drawings. FIG. 1 is an exploded perspective view showing the overall configuration of the apparatus of this embodiment, FIG. 2 is a cross-sectional view showing the joint of both Vessel structures enlarged from the side, and FIG. 3 is a front view showing the joint. FIG. 4 is an enlarged front view of the main part of the vehicle, and in FIG.
This heavy dump vessel is formed to be divisible, and when it is transported in parts, the left side vessel structure 2 set to a narrow width is loaded onto the right side wide vessel structure 3 and transported. Both of the Vessel structures 2 and 3 are provided with outward flange-like joint surfaces 2a and 3a that overlap with each other at their joint portions (Fig. 2), and each of these joint surfaces 2a and 3a has the same joint surfaces at multiple locations in the longitudinal direction. Holes 2b and 3b are drilled with diameter dimensions set, and each of these holes 2b,
3b are adapted to match when both Beth cell structures are joined.

A centering member 4 having a bolt through hole 4a at its axial center and a tapered taper 4b formed at the outer periphery of its tip is tightly fitted into each hole 2b of one joint surface 2a, and its head 4c is fixed to the edge of the hole 2b by welding or the like, and each hole 3b of the other joint surface 3a has a socket for the taper 4b of the centering member 4 at the tip of the shaft center. A ring member 5 having a widening opening 5a is tightly fitted, and the peripheral edge of the head 5b is fixed to the edge of the hole 3b by welding or the like.

Therefore, by fastening and fixing these centering member 4 and ring member 5 with bolts 6 and nuts 7 as shown in FIG. Centering is performed automatically and these can be joined with high accuracy.

In addition, in the above embodiment, each hole 2b, 3 is
A plurality of bolt holes are formed in the peripheral portion of b, and each hole is also fastened with bolts and nuts 8. In addition, the reference numeral 9 in FIG. 3 is a vent for exhaust gas from the engine, and as is well known, the deck plate 1a of the vessel 1 is discharged through the vent 9 provided on its lower surface. It is heated by gas to facilitate the discharge of loaded materials such as sludge.

As described above, the heavy dump vehicle according to the present invention can be easily divided and assembled using the bolts and nuts 6 and 7 via the centering member 4 and the ring member 5, so there is no material deterioration and the joints can be easily separated and assembled. positioning becomes easier, and reliability and workability can be improved.

[Effect of idea]

As described above, according to the present invention, sufficient strength of the joint can be ensured after assembly, and during assembly, the centering member and ring member are fixed to both joint surfaces, respectively. This has the advantage that the position of the joint can be easily aligned.
