Description

[Detailed description of the invention] Technical field: Regarding industrial vehicles with a counterweight,
In particular, the present invention relates to an improvement in a device for supporting a counterweight to a vehicle body.

Prior Art Counterweights mounted on industrial vehicles have auxiliary equipment such as radiators and flares installed in the space formed inside them, so when these auxiliary equipment are inspected, repaired, or loaded onto a ship, counterweights are Weights are often removed from the vehicle body. However, as shown in FIG. 1, the conventional counterweight is supported by fitting a recess (not shown) provided on the bottom surface of the horizontal portion 3 of the counterweight 1 into a convex member (not shown) fixed to the rear upper surface of the vehicle body frame 2. The horizontal movement is restricted by fitting the counterweight 1, and the structure is fastened to the vehicle body frame 2 with bolts 6 through a through hole 5 drilled in the vertical part 4 of the counterweight 1, so a special tool is required. This has the disadvantage that it requires a lot of effort to remove.

Purpose of the invention It is an object to provide a support device that allows a counterweight to be easily removed without requiring special tools or the like when attaching or detaching the counterweight.

Structure of the invention In the present invention, the counterweight has an inverted L-shape, and has a recessed part on the bottom surface of the horizontal part of the weight that fits into a convex member protruding from the vehicle body frame. A protruding convex portion is provided, and a locking plate fixed to the tip of a piston rod of a cylinder erected from the vehicle body can be brought into contact with the convex portion from above, thereby engaging the frame and the counterweight.

Embodiment An embodiment of the present invention will be described with reference to FIGS. 2 and 3. In the figure, 1 is a counterweight, and at the bottom of the horizontal part 3 of the counterweight 1, a convex member 7 is provided that protrudes from the left and right of the upper surface of the rear part of the vehicle body frame 2.
A concave portion 10 into which the convex member 7 is fitted is provided, and vertically horizontal passages are provided in the front-back direction, and the upper passage 8 has a gap sufficiently larger than the height of the convex member 7. 8 and the lower opening 9 3'
A V-shaped notch 11 is provided in the horizontal portion 3 of the counterweight 1, and at least the V-shaped notch 1 is provided in a portion of the horizontal portion 3 of the counterweight 1 that constitutes the bottom surface of the lower opening 9.
A notch 12 larger than 1 is provided to provide a cavity facing the vehicle body frame 2. In this embodiment, an upper port 8 and a lower port 9 are provided, but both ports 8 and 9 are not necessarily necessary, and the above-mentioned ports 8 and 9 are simply provided in a cavity that opens in two directions, the front side and the bottom surface of the counterweight 1. It suffices if it has a horizontal protrusion equivalent to the V-shaped notch 11. Further, on the upper surface of the rear end of the vehicle body frame 2, a cylinder 13 is provided upright from the center of the rear axle bracket.
In this embodiment, a disk-shaped locking member 15 is fixed to the tip of the piston rod 14 of No. 3. When the counterweight 1 is placed on the vehicle body, the convex member 7
is fitted into the recess 10 to restrict movement in the horizontal direction, and the cylinder 13 corresponds to the notches 11 and 12 provided in the counterweight 1, so that the main body of the cylinder 13 can be inserted into at least the notch 12. Yes, the piston rod 14 is located in the valley 1 of the notch 11.
1', but the locking member 15 is inserted into the valley part 1.
Since it is locked at the edge of the piston rod 1', the counterweight 1 can be pressed against the vehicle body by lowering the piston rod 14, and its movement in the vertical direction can be restricted. When removing the counterweight 1 from the vehicle body, the piston rod 14 of the cylinder 13 is raised to release the locking member 15 from the edge of the trough 11', so that the counterweight 1 can be hoisted by a hoist crane or the like. If the forklift is moved forward with the counterweight 1 hooked up, it will easily come off.On the other hand, in the case of installation, the forklift will be moved backwards with respect to the lifted counterweight 1, but at this time, the piston rod 1
The notch 11 through which the holder 4 is inserted has a V-shape that widens at the front, so that insertion is easy.

Effects of the invention As in this embodiment, a locking material is provided at the tip of the piston rod of the cylinder that stands up from the rear axle bracket, and when the piston rod is pulled down, the counterweight can be pressed against the vehicle body and fixed, allowing the operator to can be operated from the driver's seat without the need for tools to remove bolts, improving work efficiency.
