本発明は、ダンプカーなどの荷箱を一定の傾倒
状態に保持する荷箱降下防止装置に関する。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a cargo box drop prevention device that maintains a cargo box of a dump truck or the like in a predetermined tilted state.

つた。 Generally, when performing maintenance and inspection work on the hydraulic system of a dump truck or the like, the cargo box is tilted rearward and held in a fixed tilted state. At this time, conventionally, an unused tool box or a safety block is interposed between the cargo box and the vehicle frame to prevent the cargo box from falling. However, temporary safety support members such as tool boxes may not be able to reliably prevent the cargo box from falling, have low reliability, and are not permanently installed, so it is necessary to use appropriate safety support members each time you perform work. I had to search for it, and the work was extremely troublesome. In addition, many of the dedicated safety blocks must be stored separately when not in use, which poses a risk of powder loss and makes the work complicated.
本発明はかかる点に鑑みてなされたもので、車

装置を提供するものである。 The present invention has been made in view of this point, and it is possible to easily move the cargo box by rotatably providing a supporting member on the vehicle frame or the cargo box, and operating the supporting member to the cargo box lowering prevention position and the traveling storage position. The present invention also provides a device for preventing the fall of a cargo box of a dump truck or the like, which can securely hold the cargo box.
以下、本発明の構成を実施例について図面に基
づいて説明する。 DESCRIPTION OF THE PREFERRED EMBODIMENTS The configuration of the present invention will be described below with reference to the drawings.

傾動される。 The box lifting mechanism 8 includes a tension arm 10 whose one end is pivotally supported by the subframe 4, a lift arm 11 which is pivotally supported by the other end of the tension arm 10 and the main girder 6, and the lift arm 11 and the subframe. It is composed of a dump cylinder 12 pivotally supported by 4 and
Due to the extension of the dump cylinder 12, the cargo box 1 is tilted rearward.

オフセツトしている。 The cargo box drop prevention device 9 is composed of a support member 14 whose base end is rotatably supported 13 on the vehicle frame 5, and a stopper 15 fixed to the base end side of the support member 14. It is being Support member 14
has a substantially channel-shaped cross section, and a stopper 15 is clamped and fixed between both flanges, and the box is rotated between a cargo box lowering prevention position A, which is substantially orthogonal to the main girder 6, and a traveling storage position B, which is parallel to the main girder 6. The tip portion 14a that comes into contact with the main girder 6 when the cargo box is moved and is in the box lowering prevention position A.
The axis L connecting the and stopper 15 is offset by D with respect to the pivot 13 so that it rotates in the opposite direction to the direction of rotation of the support member 14 toward the hinge 7 side, that is, toward the traveling storage position side.

１３部とＤだけオフセツトしているので支持部材
１４は格納方向に回動し得ない。 Next, the operation will be explained. During normal driving, the support member 14 is held at the storage position B. When holding the cargo box 1 in a certain tilted state from this state, the support member 14 is rotated in the upright direction while the cargo box 1 is tilted at an angle greater than the angle at which the support member 14 can be moved to the box lowering prevention position. The stopper 15 is brought into contact with the upper part of the vehicle frame 5 and held at the blocking position A (see solid line in FIG. 1). That is, the preparation for the blocking action of the support member 14 is completed by a simple rotational operation. Subsequently, when the packing box 1 is tilted downward, the tip portion 14a of the support member 14 comes into contact with the lower part of the main girder 6 and holds the packing box 1 (see the dashed line in FIG. 1). At this time, the load of the cargo box 1 acts in the direction of the axis L, and the support member 14 cannot rotate in the storage direction because it is offset by the amount D from the pivot 13.
尚、本実施例において、支持部材１４は荷箱１

る。 In this embodiment, the support member 14 is attached to the packing box 1.
Although it is provided in the above, it may be provided in the vehicle frame 5, and although it is designed to be stored in the front direction, it may be installed with the front and back reversed and stored in the rear direction. Furthermore, although the dump truck 2 has been described, it goes without saying that the device 9 of the present invention can be applied not only to the dump truck 2 but also to various vehicles on which cargo boxes are tiltably mounted.
また、左右一対の支持部材を連結することによ
り、一方を操作すれば他方も同時にセツトするこ
とができ、操作が極めて容易である。 Furthermore, by connecting the pair of left and right support members, when one is operated, the other can be set at the same time, making the operation extremely easy.
さらにまた、支持部材にレバー等を連結する
と、安全な場所から遠隔操作が可能となる。 Furthermore, by connecting a lever or the like to the support member, remote control becomes possible from a safe location.
以上のように本発明によれば、支持部材を走行

検作業などを安全に行なうことができる。 As described above, according to the present invention, in order to hold the support member from the traveling storage position to the cargo box descent prevention position, it is sufficient to simply rotate the support member, and in this case, the load of the cargo box is transferred to the support member. It does not act in the retracting direction and at the same time does not act on the pivot portion of the support member, allowing inspection work etc. to be performed safely.
