Description

[Detailed Description of the Invention] (a) Industrial Application Field The present invention provides a garbage collection vehicle, particularly a garbage pushing device at the rear of the garbage container, which is reversed rearward and upward to perform cleaning, etc. inside the container. It is used in the field of

(b) Prior Art Generally, a garbage collection vehicle is provided with a swingable safety rod between a garbage container and a garbage pushing device, and the garbage pushing device is supported by the safety rod in an upwardly reversed position,
Cleaning and repair of garbage containers and garbage pushing devices are now being carried out.

However, since the safety rod is stored in a narrow space between the garbage container and the garbage pushing device, it cannot be made longer, and as a result, the angle at which the garbage pushing device is supported by the safety rod is small. However, there was a problem in that the workability was extremely poor when cleaning and repairing the inside of the garbage container.

(c) Problems to be solved by the invention The present invention solves the above-mentioned problems.
The auxiliary support member is rotatably connected to the main support member provided on the garbage container side, and the rotation of the auxiliary support member is restricted when the auxiliary support member is extended, so that the garbage pushing device is moved to the rear upward inverted position. It was designed so that it could be supported by

(d) Means for Solving the Problems The present invention connects the garbage pushing device to the rear opening edge of the garbage container and pivotally supports the rear upper part of the garbage container, so that the garbage pushing device can be moved as appropriate. In the garbage collection vehicle which can be reversed rearward and upward by a driving means, a base of a main support member is pivotally supported at the rear opening edge so as to be able to swing vertically, and an auxiliary support member is provided at the tip of the main support member. are rotatably connected, one of the supporting members is formed into a cross-sectional shape, and in the connection part, an engaging pin is provided on the cross-sectional supporting member side, and the engaging pin is provided on the other supporting member side. A long hole is provided in the longitudinal direction into which the auxiliary support member is fitted, and when the engagement pin is located at the base end of the long hole, the inner side of the back surface around the cross-sectional engagement pin comes into contact with the other support member. This invention relates to a safety device for a garbage collection vehicle that restricts the rotation of the vehicle.

(e) Action First, flip the garbage pushing device backwards and upwards. Next, the main support member is swung downward.

After that, the auxiliary support member is rotated and then slid toward the main support member to restrict rotation of the auxiliary support member.

Next, the dirt pushing device is brought into contact with the tip of the auxiliary support member.

Further, even if the auxiliary support member is not rotated and stored, it can be used as a safety device.

(f) Example The following example will be explained with reference to the drawings. 1 indicates the vehicle body 2.
A garbage container is mounted on the container 1, and a garbage pushing device 4 is connected to the rear opening edge 3 of the container 1, and the garbage pushing device 4 is pivoted to the rear upper part of the container 1 and is pushed rearward and upwardly by a hydraulic cylinder or the like. It's starting to be reversed.

Reference numeral 5 denotes a safety device that supports the garbage pushing device 4 that has been inverted rearward and upward, and the safety device 5 is composed of a main support member 6 and an auxiliary support member 7 connected to the main support member 6.

The main support member 6 has a long hole 8 at its base, and a pin 10 provided at the rear opening edge 3 via a bracket 9 is inserted into the long hole 8.
It is supported so that it can swing up and down around the center. Further, a recess 11 is formed in the rear opening edge 3 facing the base of the main support member 6, and when the main support member 6 is slightly lifted and rotated downward, the base of the main support member 6 enters the recess 11. Then, the base of the main support member 6 comes into contact with the wall surface of the recess 11 to stop the main support member 6 at a predetermined angle.

The auxiliary support member 7 has a cross-sectional shape and is adapted to abut and support the dust pushing device 4 at its tip.

Also, the main support member 6 which is the base of the auxiliary support member 7
As shown in FIG. 3, an engagement pin 12 is fixed to the connecting portion with the main support member 6, and the engagement pin 12 passes through an elongated hole 13 formed in the main support member 6 and is slidable on the elongated hole 13. It's summery.

The engagement pin 12 is a cross-sectional auxiliary support member 7.
It is fixed at a predetermined distance R from the inner side of the back surface part 14 of.

When the engagement pin 12 is located at the tip of the elongated hole 13, the distance from the engagement pin 12 to the tip of the main support member 6 forms a semicircle with a radius R.
The auxiliary support member 7 becomes rotatable around the engagement pin 12, and at a position where it extends out on the same line as the main support member 6, the rear part 14 comes into contact with the main support member 6 and stops rotating. It's summery.

Further, when the engagement pin 12 is located at the base end of the elongated hole 13, the distance L from the engagement pin 12 to the tip of the main support member 6 is larger than the distance R between the engagement pin 12 and the back surface part 14. Rotation of the auxiliary support member 7 is restricted.

In the embodiment, a long hole is provided in the main support member, and an engagement pin is provided in the cross-sectional auxiliary support member.
Even if the main support member is made into a cross-sectional shape and provided with an engagement pin, and the auxiliary support member is provided with a long hole, similar effects can be obtained.

The present invention has the above-mentioned configuration, and the operation will be explained next. When cleaning or repairing the inside of the container by inverting the garbage pushing device 4 backward and upward, , extend the safety device 5 as shown in FIG.

That is, when the main support member 6 is slightly lifted from the stored state and then rotated in the direction of the arrow in figure a, the main support member 6 comes into contact with the recess 11 and stops at a predetermined angle.

At this time, since the distance L from the engagement pin 12 to the tip of the main support member 6 is greater than the distance R between the engagement pin 12 and the back surface portion 14, rotation of the auxiliary support member 7 is restricted.

Next, when the auxiliary support member 7 is pulled in the direction of the arrow in Figure b, the distance from the engagement pin 12 to the tip of the main support member 6 becomes R, so the auxiliary support member 7 is pulled in the direction of the arrow in Figure C.
can be rotated.

If the auxiliary support member 7 is extended in the direction of the arrow after being extended as shown by the solid line in Figure d, the distance from the engagement pin 12 to the tip of the main support member 6 will be L, so the auxiliary support member 7 will be in an extended state. The dust pushing device 4 is fixed at the tip of the auxiliary support member 7.
is supported by contact.

When storing the safety device 5, it can be stored by performing the operation opposite to the above.

Incidentally, when there is no need to make a major reversal such as when repairing the dust pushing device 4 itself, it can be used as a safety device even if the auxiliary support member 7 is stored as shown in FIG.

(g) Effects of the Invention As described above, the present invention provides a main support member with an auxiliary support member that can extend out, one of which has a long hole, and the other member with a cross-sectional shape that can slide over the long hole. An engagement pin is provided so that when the auxiliary support member is extended, the cross-sectional back part comes into contact with one of the members and the auxiliary support member is fixed, so the inversion support angle can be increased with a compact device. It can increase work efficiency.
