Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to an outrigger device for a mobile work vehicle that operates at a construction site of a building.

[0002]

[Prior art]

 In traveling work vehicles, an outrigger device is attached to the vehicle body to improve the stability of the vehicle body during work.For this outrigger device, guide cylinders are attached to the front and rear of the vehicle body with the guide cylinder facing left and right. The movable rod is slidably inserted into the base and the caster is attached to the tip of the movable rod.When working, the movable rod is extended to increase the distance between the left and right casters to prevent the vehicle body from collapsing. It is known to push in to shorten the distance between the left and right casters to reduce the overall width of the vehicle body.

[0003]

[Problems to be solved by the device]

 With such an outrigger device, the guide cylinders attached to the front and rear of the vehicle body increase the front and rear length of the vehicle body, which is an obstacle when traveling in a narrow portion such as an indoor door opening, and the four movable rods. The operation is very troublesome because you pull out or push in.

Therefore, an object of the present invention is to provide an outrigger device for a traveling work vehicle that can solve the above-mentioned problems.

[0005]

[Means for Solving the Problems]

 A pair of left and right arms 20, 20 connected by a connecting rod 21 is connected to a pair of left and right stays 22, 22 connected by a connecting rod 24 so that the tip ends of the stays are vertically rotatable, and the base end portions of the arms 20 are connected. The first cam 26 is attached to the first cam 26, the second cam 27 and the lock pin 29 are provided at the base end of each stay 22, and the first cam 26 is detachably and rotatably fitted to the vehicle body 1 of the traveling work vehicle. An outrigger for a traveling work vehicle including a first bracket 33 having a shape, a second bracket 34 having a shape into which the second cam 27 is detachably fitted, and a lock hole 39 into which the lock pin 29 is fitted. apparatus.

[0006]

[Work]

 By pulling out the lock pin 29 from the lock hole 39 and rotating the stay 22 with respect to the first arm 20, the second cam 27 can be removed from the second bracket 34, and by rotating the arm 20 in that state. Since the first cam 26 can be removed from the first bracket 33, the outrigger 15 can be easily removed from the vehicle body 1, and the outrigger 15 can be easily attached to the vehicle body 1 by the operation opposite to the above.

[0007]

【Example】

 As shown in FIGS. 1 and 2, a caster wheel 2 and a steering / driving wheel 3 are mounted on a vehicle body 1 to form a traveling carriage 4, and a fixed mast 5 is attached to the rear surface of the vehicle body 1 and fixed thereto. A movable mast 6 is vertically slidable along the mast 5, and an elevating body 7 is provided along the movable mast 6. The elevating body 7 and the movable mast 6 are elevated and lowered by a lift cylinder (not shown). The mechanism 8 is configured. A loading platform / driver's cab 9 is horizontally attached to the elevating body 7 so as to face forward, and a work machine body 10 is attached to the elevating body 7 so as to be pivotable in a horizontal plane direction. The parallel four-joint link 11 is supported, the second parallel four-joint link 12 is supported on the first parallel four-joint link 11, and the work support mechanism 13 is provided at the tip of the second parallel four-joint link 12. The working machine 14 is constructed by the above, and the outriggers 15 are detachably attached to the left and right side surfaces 1a, 1a of the vehicle body 1.

As shown in FIG. 3, the outrigger 15 connects a pair of left and right arms 20 and 20 with a pair of connecting rods 21 and 21 at a predetermined interval, and connects the left and right arms 20 and 20 to the left and right. A pair of stays 22 and 22 are connected at their tip end portions by a pin 23 so as to be vertically swingable, and a pair of left and right stays 22 and 22 are connected to each other by a connecting rod 24. And the first cam 26 on the outer surface of the base end, the second cam 27 on the outer surface of the base of each stay 22, and the lock on a U-shaped bracket 28 provided on the upper end of the base end. The pin 29 is inserted and the spring 30 is urged to project toward the base end.

A pair of mounting recesses 31, 31 are formed on the side surface 1 a of the vehicle body 1 at intervals in the front-rear direction, and mounting vertical plates 32 are mounted in the mounting recesses 31, respectively. A first bracket 33 is attached to the lower part of the attachment vertical plate 32, and a second bracket 34 is attached to the upper part. Each of the first cams 26 has an elongated shape having a pair of width-direction parallel surfaces 26a, 26a facing each other and a pair of longitudinal arc surfaces 26b, 26b facing each other. The first bracket 33 has a length equal to that of the first cam 26. A circular plate 35 having the same circular groove 35 having the same curvature as the circular surface 26b and an opening groove 36 having the same width as the width of the first cam 26 which opens the circular hole 35 to the upper end surface 33a is formed as shown in FIG. As shown in the drawing, the first cam 26 is detachably attached to the first bracket 33 so as to be vertically rotatable and supported. The second cam 27 has a rectangular plate shape, and the second bracket 34 has a plate shape having an obliquely upward rectangular groove 37 which is opened on a side surface. As shown in FIG. 5, the second bracket 27 is slanted obliquely from above. A lock hole 39 is formed in a plate 38 fixed to the inner surface of the second bracket 34 so that it can be fitted and fixed downward. 40 is a limit switch.

As shown in FIGS. 6 and 7, the outrigger 15 fits the first cam 26 into the circular groove 35 of the first bracket 33 and the second cam 27 into the rectangular groove 3 of the second bracket 34. 7, the lock pin 29 is fitted into the lock hole 39, and is attached to the vehicle body 1. The caster 25 is slightly separated from the floor surface, and when the vehicle body 1 tilts left and right, the caster 25 is placed on the floor surface. I make contact with them.

Next, the work of removing the outriggers 15 will be described. The lock pin 29 is pulled out against the spring 30 and pulled out from the lock hole 39, the left and right stays 22 are pulled toward you, the second cam 27 is separated from the rectangular groove 37 of the second bracket 34, and the stay 22 is removed from the vehicle body 1. remove. As a result, the limit switch 40 is turned off. The stay 22 is lifted to rotate the first cam 26 of the arm 20 into the circular groove 35 of the first bracket 33 and rotate upward to match the width of the first cam 26 with the opening groove 36 of the first bracket 33. Then, in this state, the arm 20 is lifted right above to disengage the first cam 26 from the opening groove 36 and remove the arm 20 from the vehicle body 1. When attaching the outriggers 15, the order may be reversed. The limit 40 turns on when the outrigger 15 is attached, and turns off when the outrigger 15 is removed. Therefore, if the limit switch 40 is incorporated in the drive circuit of the lifting mechanism 8 and the limit switch 40 is not turned on, the lifting mechanism 8 does not move upward. As a result, the monitor can be operated, which can prevent the working machine 14 from rising and the vehicle body 1 to tip over when the outrigger 15 is not properly mounted, which is safe.

[0012]

[Effect of device]

 By pulling out the lock pin 29 from the lock hole 39 and rotating the stay 22 with respect to the first arm 20, the second cam 27 can be removed from the second bracket 34, and by rotating the arm 20 in that state. Since the first cam 26 can be removed from the first bracket 33, the outrigger 15 can be easily removed from the vehicle body 1, and the outrigger 15 can be easily attached to the vehicle body 1 by the operation opposite to the above. Therefore, when traveling in a narrow portion, the outrigger 15 can be removed for smooth traveling, and the work of attaching and detaching the outrigger 15 can be facilitated.
