Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial application] The present invention relates to a mounting structure for a guard frame of a truck carrier.

[Prior Art] As shown in FIG. 7, a guard frame 6 is erected at a front position of the deck 2 of the truck carrier 1 in order to protect the driver's cab from load and the like. The guard frame 6 is generally attached by means of fixing the lower end portions of the left and right vertical bars 61, 62 to the left and right side frames 21, 22 of the deck 2 with a gusset plate 8 or the like. Left and right tilt 3A, 3B
In the case of a fixed type, means for fixing to these front edges are taken.

[Problems to be solved by the present invention] By the way, a load is applied to the guard frame 6 from each direction due to a load or the like.
It is transmitted to the carrier members such as A and 3B, and the carrier members are deformed together with the guard frame 6. In particular, deformation is likely to occur at the joint portion. In order to prevent this deformation, it is necessary to strengthen each of the bed members connected to the guard frame 6.

Then, this invention aims at providing the attachment structure of the guard frame which prevents the said deformation | transformation from occurring, without modifying a loading platform.

[Means for Solving the Problem] The present invention is characterized in that a guard frame is directly fixed to a chassis frame on which a vehicle body of a truck is mounted, independently of a luggage carrier. More specifically, FIGS. 1 to 3
As shown in the figure, the lower portions of the left and right vertical bars 61, 62 of the guard frame 6 are fixed to the side surfaces of the left and right chassis frames 4A, 4B. Alternatively, as shown in FIGS. 4 to 6, the lower horizontal bar 66 of the guard frame 6 is fixed to the upper surfaces of the chassis frames 4A and 4B.

[Effects] In the present invention, the guard frame is directly fixed to the chassis frame, which is the most stable component of the truck, so that the load can be directly transmitted to the chassis frame. It is strengthened and prevents the conventional deformation.

[Embodiment] FIGS. 1 to 3 show a first embodiment.

The guard frame 6 which is erected at the front end of the loading platform 1 to protect the operator's cab is a pair of left and right vertical bars 61, 62 and a horizontal bar 6 connecting these at the upper and middle positions thereof.
It consists of 3 and 64. The vertical bars 61, 62 have a closed cross section in which steel plates having a U-shaped cross section are welded, and the lower ends thereof are fixed to the left and right chassis frames 4A, 4B, respectively.

That is, a bracket 7 having a hat-shaped cross section is arranged at the lower ends of the vertical bars 61, 62 so as to wrap them.
Both ends of are fastened with bolts 9 to the outer surfaces of the chassis frames 4A and 4B. As a result, the vertical bars 61 and 62 are firmly tightened and fixed to the chassis frames 4A and 4B.

4 to 6 show a second embodiment.

The guard frame 6 consists of a pair of left and right vertical bars 61, 62.
And the upper horizontal bar 65 that joins these upper ends
And a lower horizontal bar 66 connecting the lower ends. The lower horizontal bar 66 has a pipe shape and both ends are welded to the lower ends of the vertical bars 61 and 62. A bracket 70 is welded to the lower horizontal bar 66 at positions corresponding to the left and right chassis frames 4A and 4B, and these are fastened and fixed to the upper surfaces of the chassis frames 4A and 4B with bolts 9. In the figure, 71 is a deck mount bracket, and the deck is supported by a plurality of brackets 71 via cross members (not shown). 23 is a deck header board at the front end of the deck.

However, in the guard frame 6 of each of the above-mentioned embodiments, since it is fixed to the chassis frames 4A and 4B instead of being conventionally attached to the loading platform, the load to the guard frame 6 is directly transmitted to the chassis frames 4A and 4B. By effectively utilizing these strengths, the guard frame can be strengthened and the load bearing capacity can be greatly improved. According to the mounting structure of the present invention, for example, a detachable simple crane can be mounted on the guard frame 6 to perform cargo handling work. In the second embodiment, the vertical bars 61 and 62 can be arranged at a larger interval than the loading platform, and the deck header board 23 at the front edge of the deck can be located between the vertical bars 61 and 62 or in front of it. It is possible to increase the inner dimensions of the front and rear of the luggage carrier.
