Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a manual outrigger device used in a vehicle-mounted crane.

[0002]

2. Description of the Related Art As an outrigger device for supporting the load of a crane and preventing it from falling during a work, there are a hydraulically actuated device and a manually operated outrigger device. Since a hydraulically-operated type device is large and expensive, a manual outrigger device is used for a small vehicle-mounted crane.

In a conventional manual outrigger device, as shown in FIG. 8, a pin 85 is used to rotate a connecting member 84 having a handle 83 at the tip of a lateral rig 82 fitted in a base 81. The vertical rig 86 is rotatably supported on the connecting member 84 by a pin 87, and connecting fixing holes 90 and 91 are provided on the connecting member 84 and the vertical rig 86, and the connecting rig is installed at a working position. In this state, there is a structure in which the connecting member 84 and the vertical rig 86 are fixed to each other with a fixing pin (see Utility Model Registration No. 2553284).

[0004]

However, this manual outrigger device requires a large amount of force because the handle 83 must be pushed down by hand to jack up the vehicle at the time of installation, which makes installation work difficult. Further, since the connecting member 84 is rotatably supported by the tip of the lateral rig 82 about the pin 85 as a fulcrum, the connecting member 84 is rotatably supported.
When pushing down the handle 83 of the
If the position is not appropriate, it may be installed diagonally as shown in FIGS. 9 (a) and 9 (b). Even if the vertical rig 86 is installed correctly, it may be dislocated if an external force acts on the lower part of the vertical rig 86 to remove the foot.

Further, in the case of performing the operation of unloading the load loaded on the bed of the vehicle by the vehicle-mounted crane, when the manual outrigger device is installed, the vehicle is sunk by the load of the load (the position of the base 81 is However, since the vehicle floats up when the load is unloaded (the position of the base 81 rises), the ground plate 88 may separate from the ground during the work, and the vertical rig 86 may swing around the pin 85 as a fulcrum. There is also.

The present invention solves the above problems in a manual outrigger device, and can reduce the effort of jacking up a vehicle at the time of installation, and the vertical rigger can be installed obliquely without swinging or can be removed. It is an object of the present invention to provide a manual outrigger device that does not cause

[0007]

In a manual outrigger device of the present invention, a horizontal rig is fitted in a base so as to be able to move in and out, and a vertical rig is pivotally supported at the tip of the horizontal rig so as to be vertically rotatable. A pin hole for fixing the vertical rig vertically to the horizontal rig and a vertical rig fixing pin are provided at a predetermined distance from the pivot point of the rig, and the inner box is fitted into the vertical rig so that it can be inserted and removed freely. The rig and the inner box are connected via an actuating link and a follower link, and the actuating link is provided with an installation operation pedal and a pin hole and a link fixing pin for preventing the actuating link from rotating in the installed state Solves the above-mentioned problems.

When this manual outrigger device is installed, first the lateral rig is pulled out to the side from the base, and the vertical rig is turned 180 degrees downward about the turning fulcrum, so that the lateral rig is disengaged. Make it vertical, and insert the vertical riga fixing pin into the pin hole to fix it. Then, when the link fixing pin is pulled out, the inner box comes out by its own weight and is grounded. Therefore, the pedal for installing the operating link is depressed, the inner box is pushed out to jack up the vehicle, and the link fixing pin is inserted into the pin hole for preventing the operating link from rotating in the installed state.

In this manual outrigger device, since the vertical rig is fixed vertically to the horizontal rig, the vertical rig is not installed diagonally, and rotation of the operating link is prevented when the link fixing pin is inserted. Therefore, there is no risk of the vertical rig coming off during the work. Also, when performing the work of unloading the load, even when the vehicle is lifted by unloading the load
The vertical rig does not swing and is highly safe.

Since the vehicle is jacked up at the time of installation by depressing the installation operation pedal, the labor is reduced and the installation is easy. When storing the manual outrigger device, pull out the link fixing pin, raise the installation operation pedal to raise the inner box, and fix the inner box in the storage position with the link fixing pin. Next, the vertical rig fixing pin is pulled out, the vertical rig is rotated 180 degrees upward, and fixed by the vertical rig fixing pin. After that, the horizontal rig is closed and stored in the base.

Further, if a plurality of driven link mounting holes are provided vertically at a predetermined distance from each other, the height of the inner box can be appropriately adjusted according to the height of the vehicle.
