Abstract

(57) [Summary] [Purpose] To provide a cleaning work vehicle with a boom that can always maintain good stability of the vehicle body regardless of the direction in which the boom is extended. [Structure] In a cleaning work vehicle with a boom 1, which is provided with a boom 7 that can be freely extended and bent, and a pump 10 that supplies cleaning water to a pressure-feeding tube 14 that has a discharge port 15 at the end of the boom 7, a vehicle body rear loading platform. A pair of outriggers 3 that can project from the front end portion of the vehicle 2 toward both sides of the vehicle body and diagonally forward are provided.

Description

[Detailed description of the device]

[0001]

[Industrial application]

 The present invention relates to a cleaning work vehicle with a boom that has a long boom that can be freely extended and bent, and that uses a pressure-feed tube along the boom to discharge cleaning water to a required location in a space for cleaning work.

[0002]

[Prior Art]

 In a washing work vehicle equipped with a long boom, the outriggers are vertically extended toward both sides of the vehicle body to prevent the vehicle body from tipping over when the boom is extended, and the vehicle is supported. However, conventionally, as shown in FIG. 4, the outriggers 22 are often arranged in a pair near the center of the vehicle body 21 and one pair at the rear of the vehicle body, and when the boom 23 is extended toward the front of the vehicle body, It was difficult to keep stable.

[0003]

[Problems to be solved by the device]

 An object of the present invention is to provide a cleaning work vehicle with a boom that can always maintain good stability of the vehicle body when the boom is extended regardless of the extension direction.

[0004]

[Means for Solving the Problems]

 The gist of the present invention which solved such a problem is as follows. A washing work vehicle with a boom, which is equipped with a pair of outriggers that can be extended diagonally forward from both sides of the vehicle body from the front end of the rear body carrier. 2) A boom that can be extended and bent, and at the end of the boom. In a cleaning vehicle with a boom equipped with a pump that supplies cleaning water to a pressure-feeding tube that has a discharge port, a set of radial projections that can extend radially diagonally forward and diagonally rearward from both sides of the vehicle from the front end of the rear loading platform of the vehicle body. It is a cleaning work vehicle with a boom characterized by having an outrigger.

[0005]

[Action]

 According to the present invention, the outrigger provided at the front end of the rear part of the vehicle body, that is, near the center of the vehicle body supports the vehicle body in a state of being extended toward the diagonally forward sides on both sides of the vehicle body. Therefore, a larger distance from the outrigger at the rear of the vehicle body can be set compared to the conventional one, and the vehicle body can be supported at a position closer to the front of the vehicle body than the conventional one, even if the boom leans forward when the boom is extended. It can maintain good stability and work safety.

Further, an outrigger that can be extended not only diagonally forward of the vehicle body side but also diagonally rearward is also provided so that the vehicle body can be supported by radially extending outriggers from around the center of the vehicle body. In that case, the vehicle body is supported by three outriggers on one side, including the outriggers at the rear of the vehicle body, for a total of six outriggers, and the stability of the vehicle body can be further enhanced.

[0007]

【Example】

 Examples will be described with reference to the following drawings. FIG. 1 is a plan view showing a first embodiment, FIG. 2 is a side view of the same, and FIG. 3 is a plan view showing a second embodiment.

First Embodiment (See FIGS. 1 and 2) A cleaning work vehicle 1 according to the present embodiment includes a pair of front outriggers 3 that can be extended from a front end portion of a rear body carrier 2 to a diagonally forward side of the vehicle body. The rear outriggers 4 which can be laterally extended at the rear end of the vehicle body are provided with a pair of four outriggers 3 and 4. In the figure, 5 is a cylinder for moving the front outrigger 3 forwards and backwards, 6 is a cylinder for moving the rear outrigger 4 forwards and backwards, 7 is a boom, 8 is a post for supporting the root end of the boom 7, and is mounted on the platform 2 so as to be rotatable. ing. Reference numeral 9 is a water storage tank, 10 is a pump, 14 is a pressure feeding tube, and 15 is a discharge port.

Further, according to the present invention, since the cylinder 5 for advancing and retracting the front outrigger 3 is obliquely arranged, the post 8 is positioned further forward than the conventional arrangement of the cylinder 24 and the post 25 shown in FIG. Therefore, it is possible to provide the boom 7 longer than the conventional one. Moreover, it has a simple structure and can improve the stability of the vehicle body when the boom is extended.

Second Embodiment (see FIG. 3) In the washing work vehicle 11 of the present embodiment, four outriggers 13 that can be radially extended obliquely forward and rearward of the vehicle body side are provided at the front end portion of the vehicle body rear loading platform 12. Is installed. By doing so, the stable supporting force of the vehicle body can be further enhanced as compared with the first embodiment. The rest of the configuration may be the same as that of the above-mentioned embodiment, and will be omitted.

[0011]

[Effect of the device]

 Since the present invention is configured as described above, it is possible to equip a longer boom than a conventional washing work vehicle, and with a simple structure, it is possible to maintain good stability of the vehicle body during boom extension, Even if the boom leans toward the front of the vehicle body, it can be safely used for cleaning operations.
