Description

[Detailed Description of the Invention] Industrial Application Field This invention relates to a body system for a cargo handling vehicle such as an order picking truck.

Prior Art Conventionally, cargo handling vehicles such as order picking trucks in which the driver's seat moves up and down include the standard type shown in Fig. 1 that uses a flat pallet, as well as the high-lift type shown in Fig. 2 and the fork-handling type. There is a type shown in Fig. 3 in which various types of workbench b are fixed on top a, and the distance between axles L is
Since the vehicle bodies c were manufactured with different distances between the wheels and the distances W between the wheels, there were many different types of vehicle bodies c to be manufactured, resulting in problems such as poor productivity.

Purpose of the invention This invention was made with the purpose of improving the above-mentioned problems, and by manufacturing multiple leg members according to the specifications,
By combining this with a common vehicle body, the present invention aims to improve productivity by providing a vehicle body device for cargo handling vehicles that can accommodate various specifications.

Structure of the idea By manufacturing multiple types of leg members with different frame lengths and leg opening distances, and attaching the leg members selected according to the specifications to the lower frame of the common vehicle body, each time the specifications change, A body device for cargo handling vehicles that improves productivity by eliminating the need to rebuild the entire vehicle body according to specifications.

Embodiment An embodiment of this invention will be described in detail with reference to the drawings shown in FIG. A power chamber 3 housing an electric motor (not shown) and a battery chamber 4 housing a battery are installed. In addition, the lower frame 1a of the vehicle body 1
Recessed steps 1b are formed in the front-rear direction on the inner surface of the leg member 5, and the front end side of the leg member 5 is inserted into these recessed steps 1b from the front. As shown in FIG. 8, a plurality of types of leg members 5 are prepared in advance according to specifications. Of these leg members 5, ₅₁ are of standard specification, and each frame 5a has a substantially H-shape in plan with mutually parallel frames 5a and a cross member 5b connecting these frames 5a.
and on the upper surface near the connection part of the cross member 5b,
The lower part of the mast attachment member 6 is fixed. The mast support member 6 is composed of both side plates 6a erected on the frame 5a, and a battery chamber rear plate 6b connecting the rear edges of the both side plates 6a. A bearing 8 is attached to support the pin 7a which is more protruding. The lower end of the mast 7 is fixed to the front surface of the cross member 5b by a fixing member 9, and
A mounting block 11, which is connected to the lower frame 1a of the vehicle body 1 by means of a fixing member 10, is fixed to the outer surface of the lower end of the vehicle body 1.

On the other hand, a wheel 12 is provided at the lower part of the rear end side of the frame 5a of the leg member 5, and a recessed step 5c is formed at the front end.
A cross member 1c, which is suspended horizontally on the lower frame 1a of the vehicle body 1, is fitted into the cross member 1c from below. Further, the rear end of the frame 5a and the cross member 1c are connected by a fixing member 13.

The above embodiment shows the leg member 5 in the standard specification, but in the case of the high-lift specification or the specification in which various workbenches are attached to the fork, the length of the frame 5a as shown in FIG. Leg members 5 ₂ longer than the standard specification 5 ₁ and leg members 5 ₃ whose rear ends are opened in a crank shape are manufactured in advance, and depending on the specifications, these leg members 5 ₂ and 5 ₁ can be attached to the common vehicle body 1. It is designed to be attached to the Also, masts 7 with different heights are prepared depending on the lift height, and in the case of a high lift, the mast 7 ₁ is attached.

In addition, 14 in the figure indicates the concave stepped portion 1b of the lower frame 1a and the frame 5 when the leg member 5 is attached to the vehicle body 1.
15 is a shim inserted between the upper surface of the mast 7 and the cross member 5b to adjust the bending of the lower frame 1a and the frame 5a;
Each shows the shims for adjusting the angle.

Effects of the invention As described in detail above, this invention has a plurality of types of leg members 5 with different lengths and leg opening distances of the frame 5a.
Since the leg members 5 are manufactured and attached to the common vehicle body 1 according to the specifications, there is no need to remake the entire vehicle body each time according to the specifications, unlike in the past. This improves productivity, and during operation, the load (Wf is the front wheel load, Wr is the rear wheel load, f _I is the force pushing the lower frame 1a and frame 5a together, f _L is the force applied by the frame 5a and the cross member 1c), so even if the fixing device 10 connecting the middle part of the vehicle body frame 1a and frame 5a breaks, the load f _I will only increase and the vehicle body will Since the main body 1 and the leg members 5 are not separated, safety can also be ensured.

Also, the battery chamber rear plate 6b of the mast support member 6
By preparing in advance the leg member 5 which is shifted rearward, the capacity of the battery chamber can be expanded, making it possible to carry a large amount of batteries.
