Description

[Detailed description of the invention] (a) Industrial application field The present invention is used in the field of dump trucks equipped with a support that acts as a buffer between the vehicle body and a tiltable cargo box.

(b) Prior art In general, in the case of a dump truck whose cargo box can tilt on the vehicle body, if the cargo box is placed in direct contact with the vehicle body,
There is a risk that the two will rub against each other while driving and the vibrations of the cargo box will be transmitted directly to the car body, deforming the car body or causing cracks. It acted as a buffer.

(c) Problems that the invention aims to solve However, with the conventional tree bracket mounting structure, holes are drilled vertically in several places in the tree, screw holes are also provided in the car body, and bolts are inserted through both holes. The receiver is fixed to the car body, but the strength of the car body is reduced because screw holes are drilled into the car body, and it is very troublesome to align both holes.Furthermore, it is necessary to make sure that the bolts do not protrude from the top of the receiver. There were various problems, such as the need for special hole machining.

(d) Means for Solving the Problems The present invention is an attempt to solve the above-mentioned problems.In a dump truck in which a cargo box is tiltably mounted on the vehicle body, an opening is provided on the upper surface of the vehicle body. A pair of U-shaped mounting members having openings facing each other are fixed at intervals in the front and rear, and a bracket is fitted between the pair of mounting members to act as a buffer between the vehicle body and the cargo box. This invention relates to a structure for attaching a receiver to a dump truck, in which the receiver is attached to the vehicle body by horizontally passing a coupling means through the mounting member and the receiver.

(e) Embodiment An embodiment will be described below with reference to the drawings. Reference numeral 1 denotes a vehicle body, and the vehicle body 1 has a structure in which a subframe 3 is fixed on a chassis frame 2.

A cargo box 4 is mounted on the subframe 3,
It is connected to the subframe 3 via a hinge 5 pivotally supported at the rear end of the subframe 3, and the cargo box 4 is lifted by an appropriate launching means (not shown) provided between the subframe 3 and the cargo box 4. It is designed so that it can be tilted backwards.

6 is a bracket provided on the top surface of the subframe 3;
The support 6 acts as a buffer between the subframe 3 and the main girder 7 of the cargo box 4 located above the subframe 3.

Reference numerals 8 and 8 denote a pair of mounting members for attaching the receiver 6 to the subframe 3 side, and the mounting members 8 and 8 are formed in a U-shape so that the ends of the receiver 6 can be fitted from above. Opening 9 on the top surface of the frame 3,
9 are welded back and forth so as to face each other with an interval somewhat larger than the length of the receiver 6.

A hole 11... is provided in the side surface 10 of each of the mounting members 8, 8, and the hole 11... is provided in the receiver 6 when the receiver 6 is fitted between the mounting members 8, 8.
Lateral holes 12, 12 are provided on the same line as the hole 11... and the horizontal holes 12, 12, through which bolts 13, 13 serving as coupling means are passed, and the other end is fitted with a nut 14,
14, and the support 6 is attached to the subframe 3, and the main support girder 7 is directly supported on the upper surface of the support 6.

With the above configuration, the mounting and replacement of the supporter 6 is done by tilting the cargo box 4 and tightening the bolts 13, 13 and nuts 1.
This can be done by removing 4 and 14 laterally. Although bolts and nuts are used as the coupling means in the embodiment, the present invention is not limited thereto, and pins or the like may also be used.

(f) Effect of the invention As described above, in the present invention, a pair of mounting members are fixed to the upper surface of the vehicle body in a U-shape, a bracket is fitted between the mounting members, and the bracket is attached to the mounting member using a coupling means. Therefore, unlike in the past, the strength of the vehicle body is not weakened, and the positioning of the tree support is also facilitated, significantly increasing work efficiency.

[Brief explanation of the drawing]

FIG. 1 is an overall view, FIG. 2 is a partially enlarged perspective view, and FIG. 3 is an assembled view. 3 is a subframe, 4 is a packing box, 6 is a tree support, 8 is a mounting member, and 13 is a bolt.

Claims (1)

[Scope of utility model registration request] In a dump truck in which a cargo box is tiltably mounted on the vehicle body, a pair of U-shaped mounting members each having an opening are fixed to the upper surface of the vehicle body with a space provided in front and rear so that the openings face each other. A receiver for a dump truck is constructed by fitting a receiver that acts as a buffer between the vehicle body and the cargo box between the pair of mounting members, and attaching the receiver to the vehicle body by passing a coupling means horizontally through the mounting member and the receiver. Wood mounting structure.
