Description

  The present invention relates to an arrangement of hydraulic piping and electrical wiring connected to a telescopic cylinder for tilting a garbage collection vehicle, particularly a dust collection box.

  Conventionally, in a garbage collection vehicle, a dust input box equipped with a dust loading device (not shown) can be tilted around the upper support part by the expansion and contraction of the hydraulic cylinder at the rear end opening of the dust storage box mounted on the car frame. (For example, refer to Patent Document 1).

  Specifically, as shown in FIG. 2, a dust input box 3 having a dust loading device is connected to a rear end opening of a dust storage box 2 mounted on a vehicle frame 1 so as to be tiltable with a pivot 4. ing. A hydraulic cylinder 5 for tilting the dust container 3 with respect to the dust container 2 is connected between the dust container 2 and the dust container 3.

  In the hydraulic cylinder 5, the base end of the cylinder body 51 is pivotally supported on the upper side of the rear end side portion of the dust storage box 2 via the bracket 2 a, and the distal end of the telescopic rod 52 is in the middle of the side surface of the dust input box 3. Is pivotally supported via a bracket 3a.

  And, from the dust container 2 side to the hydraulic cylinder 5, hydraulic piping and electrical wiring 6 are arranged as follows.

  These hydraulic pipes and electrical wiring 6 are arranged from the upper part of the dust container box 2 to the upper part of the dust container box 3, and then guided downward along the side surface of the dust container box 3. Connected to the tip of the telescopic rod 52.

  Accordingly, by supplying the hydraulic oil to the hydraulic cylinder 5 via the hydraulic pipe by the hydraulic pump and extending the hydraulic cylinder 5, the dust input box 3 is tilted upward to be opened.

The electrical wiring is connected to an electromagnetic valve that controls supply and discharge of pressure oil through the hydraulic pipe.

  However, with the conventional arrangement of hydraulic piping and electrical wiring as described above, if a fire occurs in the dust box or the dust storage box, the hydraulic piping and electrical wiring are easily affected by the heat from the flame. Easy to damage. Therefore, if these hydraulic pipes and electrical wiring are damaged, the dust box cannot be opened, and there is a problem that fire fighting activities cannot be performed quickly.

  The present invention has been made in view of the above-mentioned problems, and its object is to provide hydraulic piping and electrical equipment so that they are not easily affected by the heat caused by flames in the event of a fire in the dust box or the dust container. By arranging wiring, it is intended to provide a garbage truck that can open a dust box and perform fire extinguishing activities quickly.

In order to achieve the above object, a garbage collection vehicle according to the first aspect of the present invention is provided with a dust input box provided with a dust loading device at the rear end opening of a dust storage box mounted on a vehicle frame, Is pivoted to the upper side of the rear end side of the dust storage box and the other end is pivoted to the middle of the side of the dust throwing box, so that the dust throwing box is centered on the upper pivot. In the refuse collection vehicle configured to be tiltable, the hydraulic piping and the electrical wiring routed from the dust storage box side to the hydraulic cylinder are arranged along the rear end side edge of the dust storage box from the bottom of the dust storage box. It is guided upward and connected to one end side of the hydraulic cylinder without being disposed on any part of the dust container box and the dust container box .

  According to the present invention, even when a fire occurs in the dust input box or the dust container, the hydraulic piping and the electric wiring are not easily affected by the heat caused by the flame, and damage to the hydraulic piping and the electric wiring at the time of the fire is minimized. Since it can be prevented, fire extinguishing activities can be performed quickly by opening the trash input box.

  Hereinafter, embodiments of the present invention will be described with reference to the drawings.

  FIG. 1 shows a garbage truck according to the present invention. In addition, about the structural member similar to the refuse collection vehicle mentioned above, the same code | symbol is attached | subjected to the same member and description is abbreviate | omitted.

  This garbage collection vehicle is characterized by the arrangement of hydraulic piping and electrical wiring 6. Specifically, the hydraulic piping and electrical wiring 6 are connected to the rear end of the dust storage box 2 from the bottom of the dust storage box 2. It is guided upward along the side edge and is connected to the base end portion of the cylinder main body 51 which is one end side of the hydraulic cylinder 5.

  And by connecting the hydraulic piping and the electrical wiring 6 to the hydraulic cylinder 5 in this way, the hydraulic oil is supplied to the hydraulic cylinder 5 via the hydraulic piping (6) by the hydraulic pump, and the hydraulic cylinder 5 is extended. As a result, the dust box 3 is tilted upward to be opened.

  The dust container 3 is normally closed as shown in FIG. 1, and in this state, a conventionally well-known dust container in which the dust charged from the input part 31 formed at the rear of the dust container 3 is provided. It is loaded into the refuse storage box 2 by the loading device.

  At this time, a discharge plate (not shown) disposed slidably in the front-rear direction in the dust storage box 2 is sequentially moved forward by the dust loading by the dust loading device, so that the dust is stored in the dust storage box. It is loaded while being compressed to 2.

  Further, the dust container 3 is tilted upward as described above, and the discharge plate is moved from the front to the rear with the rear surface of the dust container 2 opened, thereby discharging the dust in the dust container 2 to the outside. Like to do.

  By the way, by arranging the hydraulic piping and the electrical wiring 6 as described above, even if a fire occurs in the dust throwing box 3 or the dust storage box 2, the hydraulic piping and the electrical wiring 6 are affected by the heat caused by the flame. It becomes difficult to receive. Accordingly, it is possible to prevent damage to the hydraulic piping and the electric wiring 6 at the time of a fire as much as possible, and thereby maintain a state in which the dust throwing box 3 can be opened. Therefore, by opening the dust throwing box 3, fire fighting activities can be performed. Can be done quickly.

  Moreover, since the arrangement of the hydraulic piping and the electric wiring 6 to the dust box 3 is not required, the structure can be simplified.

It is a side view which shows the refuse collection vehicle of this invention. It is a side view which shows the conventional refuse collection vehicle.
