〔Example〕

 An embodiment of the present invention will be described for a vehicle for carrying wall materials.

The vehicle body 1 and the body 2 and the pair of left and right frames 3, 3 are substantially L-shaped. The body 2 is provided with driving and steering wheels 4, and the front wheels 5 are provided in front of the pair of frames 3, 3. A working machine A is provided on the main body 2 so as to be vertically movable and laterally movable toward the front.

That is, the lifting body 6 is provided on the front surface of the main body 2 so as to be movable up and down by the lifting cylinder 7, and the first frame 8 is attached to the lifting body 6.
Is movably provided by the left and right cylinders 9, the second frame 100 is fitted in the first frame 8 by the telescopic cylinder 110 so as to be slidable forward and backward, and the mounting body 120 is provided at the front end of the second frame 100. A swing body 140 is swingably pivoted vertically at 130, a swing body 140 is swingably mounted on a mounting body 120 by a swing motor 150, and a support plate 160 is provided on the swing body 140, and a wall is provided on the support plate 160. The material is attached.

As shown in FIG. 1, the main body 2 includes a rear plate 10 and left and right side plates.
11 and the upper surface plate 12 form a box shape, the upper surface plate 12 is provided with a steering handle 13 and a control mechanism storage box 14, and a rectangular mounting frame 15 is provided on the upper surface 14a of the control mechanism storage box 14. A control box 16 is detachably fitted and mounted in the mounting frame 15.

The control box 16 is provided with a plurality of operating levers 17, one end of a cord 18 is connected, and the other end of the cord 18 is connected to the control mechanism housing box 16 to electrically connect the control mechanism and the control member. Connected to.

That is, the other end of the cord 18 is connected to the cord 20 in the control equipment storage box 16 by the connector 19 as shown in FIG. 2, and the connector 19 is connected to the one side plug 19a and the cord 20 connected to the other end of the cord 18. The other side plug 19b is connected and screwed to the upper plate 16b, and the cord 18 can be easily attached and detached by fitting the one side plug 19a to the other side plug 19b and withdrawing it.

An L-shaped bar 21 is rotatably provided in the horizontal direction of the vehicle body on the upper surface 16a of the control device storage box 16 in the horizontal direction, and a plurality of receiving members 22 are attached to the bar 21. Multiple hooks 23 are attached to the cord 18,
By engaging each hook 23 with each receiving member 22, the cord 18
The other end of the bar is detachably connected to the bar 21.

That is, as shown in FIG. 2, the bar 21 is L with the vertical rod 21a and the horizontal rod 21b.
The lower part of the vertical rod 21a is rotatably inserted into the hole 25 of the support 24 and the hole 26 of the upper plate 16b, and the flange 27 is formed into the support 2.
The retaining ring 28 is attached to the bottom of the upper plate 16b, and a pair of stoppers 29, 29 attached to the retaining ring 28 at intervals of 180 degrees interfere with the stopper pin 30 provided on the inner surface of the upper plate 16b. As a result, the bar 21 is rotated in the range of 180 degrees in the leftward posture, the rearward posture, and the rightward posture.

As shown in FIG. 4, the hook 23 has a mounting portion 23a and a hook portion 2
3b and a retaining piece 23c. When the retaining piece 23c is pushed to engage the hook portion 23b with the receiving member 22, the retaining piece 23c abuts against the tip of the hook portion 23b with a spring force so as not to be removed.

Therefore, in the case of remote control, the control box 16 is taken out from the mounting frame 15 and the cord 18 is extended. However, when the vehicle body 1 is steered left and right at this time, the other end of the cord 18 is With the bar 21, it swings to the left and right with respect to the vehicle body, and the vehicle body side attachment portion, that is, the connector 19 portion is not subjected to an excessive force and is not damaged.

Further, since the bar 21 is provided at the center of the left-right direction of the vehicle body, the swinging motion can be minimized when steering to the left and right.

In addition, since the rotation range of the bar 21 is restricted to 180 degrees in the leftward posture, the rearward posture, and the rightward posture, the bar 21 rotates 360 degrees and an unreasonable force acts on the connector 19 part. And the bar 21 does not interfere with the work implement A in the forward posture.

Further, since the other end of the cord 18 is connected to the bar 21 by engaging the hook 23 with the receiving tool 22, it can be easily connected or disconnected, and the connector 19 can be easily attached and detached from the vehicle body side. Since it is possible, the cord 18 together with the control box 16 can be easily removed or attached from the vehicle body side.

[Effect of device]

When the operator operates the control box 16 remotely and the vehicle body is steered left and right, the other end of the cord 18 swings left and right together with the bar 21, so that an unreasonable force acts on the attachment portion of the cord 18 on the vehicle body side. It is possible to prevent damage to the vehicle body side mounting portion of the cord 18.

Moreover, the bar 21 is L-shaped with the vertical rod 21a and the horizontal rod 21b, and the vertical rod 21a is located at the center position in the left-right direction of the vehicle body 1 on the upper surface 14a of the control mechanism storage box 14 and is in the leftward, rearward, and rightward postures. Since it is rotatably supported by 180 degrees, the bar 21 does not rotate when the operator moves to the left side or the right side of the vehicle body 1 and the vehicle body side mounting portion of the cord 18 is not damaged. The operator can smoothly move to the left and right sides of the vehicle body 1 without interfering with the vehicle body. Furthermore, when the operator drives near the vehicle body 1, the control box 16 side of the code 18 hangs down on the floor, but the bar 21 near the vehicle body 1 side. The bar 21 does not hang down near the vehicle body 1 supported by the horizontal rod 21b, does not interfere with the vehicle body when the vehicle is running, and does not step on the cord 18 with wheels, and the bar 21 can rotate more than 180 degrees. Cord 18 without excessive twist The durability of the bar 21 is improved, and the bar 21 does not have a forward posture, so that the bar 21 does not interfere with the working machine.

Further, since the control 16 is fitted and detachably attached to the mounting frame 15 of the control mechanism storage box 14, the bar 21 is provided in the control mechanism storage box 14 and the cord 18 is connected, the controller 16 is provided when the remote control is not performed. The bar 21 and the cord 18 can be compactly attached by attaching the cord 18 to the control mechanism storage box 14, and the cord 18 can be attached to the bar 21 vertically.
Since the connection can be made near the support portion of 21a, damage to the attachment portion of the cord 18 can be prevented more reliably.

Further, since the cord 18 is connected to the bar 21 by the hook 23 and the receiving member 22, the cord 18 can be easily connected to and removed from the bar 21, and the other end of the cord 18 is attached to the control mechanism storage box 14. Since it is detachable, the cord 18 can be easily attached and detached, and the control box 16 and the cord 18 can be easily attached and detached.

Therefore, when the work vehicle is transported to the work site, the control box 16 and the cord 18 can be removed, and the cord 18 can be prevented from hanging and trampling and being damaged.
