Abstract

PROBLEM TO BE SOLVED: To facilitate connection and disconnection of a head guard with a working machine operation lever unit and a dashboard installed on it by constituting a forklift of the dashboard installed on the head guard and a car body frame and the working machine operation lever unit installed on a car body plate. SOLUTION: A projection part 14 of a lever bracket 12 is installed on a projection part 6 of a plate 2 of a car body frame by a bolt 16 and a nut 17 in case of installing a working machine operation lever unit 10 on a car body and a working machine operation valve 7 is installed on an inner surface of the plate 2. As the projection part 6 is projected forward rather than the dashboard 4, it is possible to singly connect and disconnect the working machine operation lever unit 10, and connection and disconnection work is also easy. Additionally, it is possible to connect and disconnect a head guard for a driver with the dashboard 4 installed on it in a state where the working machine operation lever unit 10 is installed on the car body.

The vehicle body frame, the driver's seat installed above the vehicle body frame, the dashboard supporting the steering wheel arranged in front of the driver's seat, and the operating valve for the working machine arranged on the side of the steering wheel. In a unitized structure of a forklift having a switching operation lever, the driver's head guard is detachably attached to the vehicle body frame while holding the dashboard, and detachable from the driver's head guard and left and right frames of the vehicle body frame. The dashboard is freely attached, and it is detachably attached to the plate of the body frame. That it has a configuration consisting of a working machine operating lever unit.

The working machine operating lever unit includes a working machine operating lever, an upper part of which is swingably mounted, and a lower end of which is provided with a protruding portion which is fastened to a protruding portion of a bracket at a front portion of a vehicle body frame. It comprises a lever bracket provided and a rod connecting the working machine operating lever and the working machine operating valve.

In the unitized structure of the forklift, the driver's head guard is attached to the vehicle body frame via a shock absorber.

[0010]

With the above structure, the lever bracket of the working machine operating lever unit can be fastened to the bracket of the vehicle body frame outside the dashboard, and the working machine operating lever unit or the head guard equipped with the dashboard can be mounted. Each can be attached and detached independently.

[0011]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT An embodiment of the unitized structure of a forklift according to the present invention will be described in detail below with reference to the drawings.

FIG. 2 is a detailed side view of the driver's head guard portion. The driver's head guard 3 is mounted on the upper surface of the vehicle body frame 1 via cushioning devices 18a and 18b. Left and right frames 1L, 1R are provided at the front of the body frame 1.
The plate 2 that connects the two is fixed. A dashboard 4 is detachably attached to the driver's head guard 3 at the lower front of the driver's seat.

FIG. 3 is a side view of the first embodiment of the working machine operating lever unit, and FIG. 4 is a view taken in the direction of arrow X. The plate 2 attached to the front part of the body frame 1 is provided with a protrusion 6 projecting forward from the dashboard 4 on the upper end of the plate 2, and the working machine operation valve 7 is provided on the inner surface of the plate 2 on the driver side. It is attached by bolts 9. The work implement operating lever unit 10 includes work implement operating levers 11a, 11b, 1
1c, a lever bracket 12 having a protrusion 14, and

In the above structure, the working machine operating lever unit 10 has a shaft 13 attached to an upper portion of a lever bracket 12 having a protrusion 14 at a lower end thereof, and the working machine operating levers 11a, 11b, and 11c rotate on the shaft 13. It is attached freely. Work machine operating levers 11a, 11b, 1
Rods 15a, 15b and 15c are connected to a lever 11e at the other end of a shaft 13 attached to 1c. Rod 1
5a, 15b and 15c are connected to the spool 7a of the working machine operation valve 7. Therefore, the work implement operating lever unit 10 includes the work implement operating levers 11a, 11b, 1 and 1.
1c, a lever bracket 12 having a protrusion 14, and
The shaft 13 and the rods 15a, 15b, 15c are
Can be combined as an assembly outside the forklift.

When the working machine operating lever unit 10 is mounted on the vehicle body, the protrusion 14 of the lever bracket 12 is attached to the protrusion 6 of the plate 2 of the vehicle body frame 2 by the bolts 16,
The work machine operation valve 7 is attached to the inner surface (driver side) of the plate 2 while being tightened by the nut 17. Since the projecting portion 6 projects forward from the dashboard 4, the work machine operation lever unit 10 can be independently attached and detached, and the attachment and detachment work is easy. Further, the work machine operation valve 7 can be attached from the dashboard 4. Further, it is possible to attach / detach the driver's head guard 3 with the dashboard 4 still attached while the work implement operation lever unit 10 is attached to the vehicle body.

FIG. 5 is a side view of the second embodiment of the working machine operating lever unit 10A. In the first embodiment, the protrusion 1
Although the lever bracket 12 provided with 4 is attached to the plate 2 of the vehicle body frame 2, in the second embodiment, the lever bracket 12A is attached to the body 7b of the working machine operation valve 7 with the bolt 19. Therefore, the working machine operating lever unit 10A includes the working machine operating levers 11a and 11a.
Lever bracket 1 including b and 11c and protrusion 14
2, a shaft 13, rods 15a, 15b and 15c, and a working machine operation valve 7.

When the working machine operating lever unit 10A is mounted on the vehicle body, the working machine operating valve 7 connected to the working machine operating lever unit 10A is fastened to the plate 2 of the vehicle body frame 2 with bolts 9.

[0017]

Since the present invention is configured as described above,
The work machine operating lever unit can be independently attached to and detached from the vehicle body. Therefore, the work implement operating lever unit can be attached / detached even when the driver's head guard with the dashboard is attached to the vehicle body, and the work is easy because the fastening portion projects to the outside of the dashboard. Also,
A forklift unitized structure in which the driver's head guard can be attached and detached even when the work implement operation lever unit is attached to the vehicle body is obtained.
