という問題がある。 In this type of pallet transport vehicle, a connecting frame connected to an operating source for raising and lowering the fork is installed at the rear of the fork, and an operating rod is placed on the base of the operating source in an upright position extending approximately vertically. , and an inclined position tilted at a predetermined angle rearward from this position. It is known that the device is tilted to a tilted position rather than an upright position. in this case,
The operating rod is generally tilted at an angle of 45 to 60 degrees to make it easier to tow the vehicle to the rear, but the angle of inclination of the operating rod is large, making it difficult to pull the vehicle backwards. The problem is that it is difficult.

を介して枢着される。 Embodiments of the present invention will be described below with reference to the drawings. 1 to 3 show a first embodiment, in which reference numeral 1 denotes a pair of left and right forks equipped with wheels 2 at the front, and a connecting frame 4 is erected on a rear connecting plate 3 of the forks. An operating rod 6 of a hydraulic system 5 as an operating source for raising and lowering the fork is connected to the rear end of the connecting frame 4, and the hydraulic system 5 has a base 8 with wheels 7. The base 8 and the connecting frame 4 are connected by a connecting member 9
The fork-shaped lower end 11a of the operating rod 11 is connected to the support part 10 on the base 8 by a pivot 12.
It is pivotally connected via.

斜位置まで倒されるようになつている。 When the operating rod 11 is pushed forward to move the vehicle forward, it is held in an upright position extending approximately vertically; however, when the operating rod 11 is towed backwards to move the vehicle backward, it is normally held at a position of 45 to 45 mm. It is designed to be tilted back to a tilted position of 60 degrees.

得るように枢軸１４により取付けられている。 On the top surface of the connecting frame 4, there is a hook 13 that can be engaged with and detached from the operating rod 11, as shown clearly in FIG.
is attached by a pivot shaft 14 so that it can rotate approximately 90 degrees in the left and right direction from the rearward protruding position.

作業を行うことができる。 In the above configuration, if the work area is large, the hook 13 is rotated to the left or right, and the operating rod 11 is tilted at an angle of 45 degrees to the rear, for example, and pulled backward to move the vehicle backward. . on the other hand,
The work space is small and the operating rod 11 cannot be tilted 45 degrees.
Or, if you find that it will be difficult to tow if it is pushed down that much, hold the operating rod 11 in the upright position and rotate the hook 13 to lower the operating rod 1.
1 and tilt the operating rod 11 backward slightly, the hook 13 engages with the operating rod 11, and the operating rod 11 is restricted from tilting backwards near the upright position. Can perform towing work.

It was a strong force. When the operating rod 11 is engaged with the hook 13, the retaining piece 15 is pushed by the operating rod 11 and rotates as shown by the chain line to allow the operating rod 11 to pass through the opening. After it is engaged with the hook 13 by tilting it slightly backward, it is engaged with the tip of the hook to prevent the operating rod 11 from coming off the hook 13.

率向上に大いに寄与し得る。 As described above, according to the present invention, the connecting frame 4 connected to the actuation source 5 for raising and lowering the fork 1 is provided at the rear of the fork 1, and the connecting frame 4 is erected at the rear of the fork 1.
An operating rod 11 is pivotally mounted on a base 8 so as to be rotatable back and forth between an upright position extending in a substantially vertical direction and an inclined position tilted at a predetermined angle rearward from this position. Reference numeral 11 indicates a pallet transport vehicle which is normally tilted from the upright position to a tilted position when the vehicle is towed rearward and the vehicle body is towed backward while the operating rod 11 is held near the upright position. In order to allow the vehicle body to move backwards, the connecting frame 4 is provided with a locking member such as a hook 13 that engages with the operating rod 11 located near the upright position and restricts its rearward tilting. Therefore, when using the transport vehicle in a narrow work area such as a truck loading platform, by temporarily operating the locking member such as the hook 13, the operating rod 11 can be moved backward while being held near the upright position. Therefore, even in a narrow work area, the vehicle can be easily towed backwards through the operating rod 11, which greatly contributes to improving pallet transportation efficiency.
