[Problems to be solved by the device]

 Conventionally, as described above, the load support 9 is tiltably attached to the lower part of the lift bracket 4 which is provided in the front part of the forklift truck 1 and which is vertically movable, and the forklift truck is mounted above the lift bracket 4. 1. A horizontal guide member 5 projecting forward of 1 is fixed, a pull carriage 6 is arranged on the horizontal guide member 5 so as to be horizontally movable in the front-rear direction, and a clamp plate 7 having a plurality of spikes formed on the pull carriage 6 is tilted. In the freely mounted load stabilizer, a pair of rollers 25 is rotatably arranged near the tip of the horizontal guide member 5 so that it frequently moves in and out of the refrigerator or the ice storage and the salt is attached by sea breeze. , The parts such as the roller 25 may rust early, and the parts such as the roller 25 may rust early. Roller 25 receives a large load due to point contact, and the horizontal guide member 5 may be damaged due to metal fatigue due to frequent horizontal movement of the pull carriage 6 in the front-rear direction. Excessive bending stress on the rotatably supported shaft causes the shaft to bend, and in combination with rusting, the roller 25 cannot be removed, making replacement and adjustment impossible. It was The present invention has been devised to solve the above problems.

[0004]

[Means for Solving the Problems]

 According to the present invention, a load support is tiltably attached to a lower portion of a lift bracket that is movable up and down arranged in a front portion of a forklift truck, and a horizontal guide that protrudes to a front portion of the forklift truck is provided above the lift bracket. In the load stabilizer, the member is fixed, the pull carriage is horizontally movable in the front-rear direction on the horizontal guide member, and the clamp plate having a plurality of spikes formed on the pull carriage is tiltably mounted. The above-mentioned problems are solved by the structure in which a resin shoe is detachably fixed to the tip of the.

【Example】

 An embodiment of the present invention will be described with reference to FIGS. 1, 2 and 3. FIG. 1 is a side view of a forklift truck equipped with the present invention. Reference numeral 1 is a forklift truck, 2 is a body of the forklift truck 1, 3 is a mast arranged in front of the body 2, 4 is a guide of the mast 3, and a rod of a lift cylinder (not shown). A lift bracket 5 that moves up and down by the expansion and contraction of the vehicle is a horizontal guide member fixed to the upper portion of the lift bracket 4 so as to project forward from the vehicle body 2 of the forklift truck 1, and 6 is provided so as to be horizontally movable along the horizontal guide member. Pull carriage, 7 is a clamp plate tiltably attached to the pull carriage 6, 8 is a spike having a sharp tip fixed to the lower surface of the clamp plate 7, and 9 is tiltably attached to the lower portion of the lift bracket 4. It consists of a load support tool such as a fork and bucket.

The details of the horizontal guide member will be described with reference to FIGS. 2 and 3. The horizontal guide member 5 is a pair of fixed sides that are fixed to the upper portion of the lift bracket 4 by projecting forward from the vehicle body 2 of the forklift truck 1. It comprises a guide member 5A and a movable guide member 5B which is horizontally movable while being guided by the fixed guide member 5A, and a rollable first roller 5C is provided inside the front portion of the fixed guide member 5A. A movable second roller 5D is provided in the rear part of the moving-side guide member 5B, and the first roller comes into contact with the lower surface of the protruding piece of the moving-side guide member 5B and receives a downward load. The two rollers 5D are in contact with the lower surface of the upper web of the fixed-side inner member 5A and are subjected to an upward load. Fixed side: The bottom 10A of the pull carriage moving hydraulic cylinder 10 is fixed to the rear of the guide member 5A, and the rod 10B of the pull carriage moving hydraulic cylinder 10 is fixed to the front of the moving guide member 5B. The chain sprocket 13 is rotated to the rod 10B. Support freely. One end of the chain 14 that meshes with the chain sprocket 13 is locked to the fixed side guide member 5A and the other end is locked to the pull carriage 6, and the rod 10B of the hydraulic cylinder 10 for moving the pull carriage is expanded and contracted to move together with the moving side guide member 5B. 6 also moves horizontally. As shown in FIG. 3, a resin shoe 15 having a predetermined length is detachably screwed to the tip of the fixed guide member 5A with a bolt 16.

The details of the pull carriage will be described with reference to FIG. 2. The pull carriage 6 is horizontally moved while being guided by the moving side guide member 5B. The arm 17 can be horizontally moved and tilted on the lower surface of the pull carriage 6. I am wearing it. An arm horizontal guide member 5G for guiding the horizontal movement of the arm 17 is fixed to the lower surface of the pull carriage 6 at a predetermined interval, and a lever 18 which is connected to a rod of a hydraulic cylinder described later is supported on the lower surface of the pull carriage 6. The bracket 19 is fixed to the center of the above-mentioned predetermined space. The lever 18 has a rod connecting lever member 18A connected to the rod 20A of the lever hydraulic cylinder 20 at the center, and an arm connecting lever member 18B connecting to the arm 17 and the rod connecting lever member 18A. It has a fixed structure. The rod 20A of the lever hydraulic cylinder 20 is connected to the rod connecting lever member 18A, and the arm connecting lever 18B is rotatably supported at a predetermined position of the arm 17. The clamp plate 7 is moved up and down by the expansion and contraction of the rod 20A of the lever hydraulic cylinder 20.

The clamp plate 7 is tiltably provided at one end of the arm 17, and one end of the screw type adjuster 21 is tiltably provided near the attachment position of the clamp plate 7 to the arm 17 and the other end is provided at the clamp plate 7. Is attached to. By adjusting the screw type adjuster 21, the inclination of the clamp plate 7 can be adjusted, and the spikes 8 can be driven at right angles to the ice surface.

A stopper 11 is fixed to the lower surface of the pull carriage 6, which abuts when the arm 7 is parallel to the horizontal guide member 5. When the rod 20A of the lever hydraulic cylinder 20 is contracted in the shortest direction, the arm 7 becomes parallel to the horizontal guide member 5.

【effect】

 Avoid the concentrated load, prevent the roller from being damaged, and rotate the roller by receiving the maximum load that the pull carriage 6 receives when it reaches the position farthest from the vehicle body, not by the point contact with the roller as in the past, but by the surface contact. By omitting the shaft that can be freely supported, it is possible to eliminate the inability to replace and adjust due to excessive bending stress, which is easy to use and eliminates any breakdowns, which is the most efficient way to improve cargo handling work. Make a contribution.
