Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a device for easily attaching and detaching a hub of an industrial vehicle such as a forklift.

[0002]

[Prior art]

 The hub that attaches and supports the wheels of a forklift truck, such as an industrial vehicle, is a heavy object that weighs about 50 kg.However, due to the location of the hub, the work space is too small to use a lifting device such as a crane. The reality is that they rely on human resources.

[0003] This hub attachment / detachment work is heavy work, and since the work posture is inevitably in the middle waist, there is a problem in terms of safety and health because it tends to cause back pain.

As far as the inventor knows, there has been a problem that a hub attaching / detaching device for a forklift such as an industrial vehicle has not been developed and there is no suitable commercially available product.

[0005]

[Problems to be solved by the device]

 The present invention has been made to solve the above problems, and an object thereof is to provide a hub attaching / detaching device for a forklift truck that can easily attach and detach the hub.

[0006]

[Means for Solving the Problems]

 A hub mounting attachment 1 is pivotally attached to a plate 2 which can be lifted and lowered by a jack 7 so as to be rotatable 90 ° from a horizontal position to a vertical position, and can be fixed to the horizontal position and the vertical position respectively. Is a hub attaching / detaching device for a forklift, which is characterized in that a hub support 4 having a hub mounting hole 4a adapted to the hub bolt 13 is erected.

[0007]

[Action]

 Since the present invention is configured as described above, when removing the hub, jack up with the hub attachment 1 kept horizontal, and insert the hub bolt 13 into the hub mounting hole 4a of the hub support 4. The hub can be removed by fixing it and pulling it out, turning the hub attachment 1 90 ° to the vertical position and lowering it in place. When attaching the hub, follow the same procedure in reverse. It can be carried out.

【Example】

 FIG. 1 is an overall side view of the hub attaching / detaching device of the present invention, FIG. 2a is a front view of essential parts, FIG. 2b is a perspective view, and FIGS.

In the figure, reference numeral 1 denotes a hub attachment, which is pivotally mounted on a plate 2 so as to rotate, and can be rotated 90 ° counterclockwise from the horizontal position shown in FIGS. 1 and 3a. It can be brought into the vertical position shown in FIG. 3b and can be fixed in that position by the fixing pin 3.

Reference numeral 4 denotes a hub support that is erected on the attachment 1 and has a hub mounting hole 4a that fits a hub bolt.

Reference numeral 5 denotes a rubber mat attached to the upper surface of the rear portion of the attachment 1. By pushing down the rubber mat 5, the position of the attachment 1 can be lowered.

Reference numeral 6 denotes a safety pin for fixing the attachment 1 on the plate 2 when the attachment 1 is in the horizontal position.

Reference numeral 7 is a movable garage hydraulic jack provided with wheels 7 a, and the plate 2 and the attachment 1 can be jacked up by operating a handle 8.

Reference numeral 9 is a collar corresponding to the fixing pin 3 and is composed of a collar 9 _-1 attached to the attachment 1 side and a collar 9 _-2 attached to the plate 2 side. The attachment 1 can be fixed to the plate 2 so as not to be rotatable by sandwiching the collars 9 _-1 and 9 _-2 .

Reference numeral 10 is a collar corresponding to the safety pin 6 and includes a collar 10 _-1 attached to the attachment 1 side and a collar 10 _-2 attached to the plate 2 side. The attachment 1 can be non-rotatably fixed to the plate 2 by being inserted into the collars 10 _-1 and 10 _-2 .

Reference numeral 11 is a plate mounting bolt for fixing the plate 2 to the upper surface of the support frame 7 b of the jack 7.

Reference numeral 12 is a hub, 13 is a hub bolt, and 14 is a hub nut.

When removing the hub 12 attached to the actual vehicle, first, from the state shown in FIG. 1, operate the handle 8 to jack up to the hub mounting height of the actual vehicle, and then insert the hub mounting hole 4a into the hub bolt 13 Adjust to the position.

When the positioning of the hub mounting hole 4a and the hub bolt 13 is completed, the hub nut 14 is once removed, the tip of the hub bolt 13 is inserted into the hub mounting hole 4a, and the hub nut 14 is tightened to secure the hub 12 to the hub support body. Fix at 4. (See Figure 3a)

In this state, the hub 12 can be removed by releasing the fixation between the hub 12 and the vehicle body side (not shown), and pulling out the hub as it is.

When lowering the removed hub 12, the safety pin 6 is pulled out, the hub attachment 1 is rotated 90 °, the position is fixed by the fixing pin 3, and the handle 8 is operated and the rubber mat 5 is pushed down. Then, lower the hub 12 onto the pallet and remove the hub nut 14. (See Figure 3b)

When the hub 12 is attached to the vehicle body side, the same procedure can be performed in the reverse order of the above.

[0023]

【effect】

 According to the present invention, the hub mounting attachment 1 is pivotally mounted on the plate 2 which can be lifted and lowered by the jack 7 so as to be rotatable 90 ° from the horizontal position to the vertical position, and can be fixed at the horizontal position and the vertical position, respectively. Since the hub support 4 having the hub mounting hole 4a adapted to the hub bolt 13 is erected on the attachment 1, it is possible to easily attach / detach the hub, which conventionally had to be done manually. Since the attachment 1 can be raised and lowered by the jack 7, it can be used for all models from large forklifts to small vehicles, which is extremely useful for labor saving.
