Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a cargo handling device for an industrial vehicle, and more particularly, to a device capable of suitably carrying a cargo vehicle having a small width and a small depth.

[0002]

[Prior art]

 BACKGROUND ART Conventionally, as a cargo car that stores and conveys a carton case or the like, there is one as shown in FIG. The cargo vehicle A is formed in a substantially box-like shape having an open upper surface, and caster wheels B are attached to the four corners of the lower surface.

However, when a heavy load is loaded on the cargo vehicle A, it is difficult to carry the load manually, and therefore, the low lift 20 as illustrated in FIG. 6 is often used to carry the load.

The low lift 20 includes a main body 2, a battery chamber 5 that can be moved up and down with respect to the main body 2, and a cargo table 17 fixed to the battery chamber 5. The running wheels 4 that are steered by the handle section 3 are attached.

The traveling wheels 4 are driven by an electric motor (not shown), and the battery chamber 5 and the load receiving base 17 are lifted and lowered by a hydraulic cylinder and a link mechanism (both not shown) as is well known. This can be done by raising and lowering the bracket of the road wheel 18 supported by the tip portion of the.

However, the cargo carrier 17 of the low lift 20 is inserted into the gap between the cargo vehicle A and the road surface, and the cargo vehicle A is transported by raising it by a predetermined amount. In consideration of the stability when the cargo vehicle A is loaded on the low lift 20, the cargo cradle 17 is normally inserted in the X direction in FIG. 7 for cargo handling.

[0007]

[Problems to be solved by the device]

 By the way, although there are various shapes of the cargo vehicle A, in particular, due to the demand for space saving, the shape having the height L increased while the shape having the smaller depth L and width W is increasing. . In this way, in the cargo vehicle A having the small width W and the small depth L, the dimension between the caster wheels B and B is also small, so that the cargo carrier 17 of the low lift 20 cannot be inserted and the cargo vehicle A can be transported using an industrial vehicle. There was a problem that it did not exist.

The present invention has been devised to solve such a problem, and an object thereof is to provide a device capable of favorably loading and unloading a cargo vehicle having a small width and a small depth.

[0009]

[Means for Solving the Problems]

 The present invention is a cargo handling device for an industrial vehicle, comprising: a main body having steerable drive wheels; and a pair of left and right load supports mounted to be movable up and down with respect to the main body. The pair of load supporting members are provided with locking members that can be rotated about the vertical axis and can face each other inwardly in parallel, and a driving means that can rotate the locking members. It is a cargo handling device for industrial vehicles.

[0010]

【Example】

 An embodiment of the present invention will be described below with reference to the drawings. The same parts as the conventional ones are given the same numbers.

As illustrated in FIG. 1, a pair of left and right load supports 6 is fixed to the battery chamber 5 at a predetermined interval in the low lift 1. In addition, in the present embodiment, the load support 6 is provided with a locking portion 8 which is rotatable about a vertical axis.

That is, as schematically shown in FIG. 2, the locking portions 8 are juxtaposed in front of and behind the load support 6, and are rotatably supported by the support shaft 9. The links 10 are pivotally attached to the front and rear locking portions 8 by pins 14 and 15, respectively.

The hydraulic cylinder 11 is structured such that its base end is rotatably fixed to the load support 6 by a pin 13 and its piston rod 12 is connected to the pin 15. Therefore, as shown in FIG. 3, when the piston rod 12 of the hydraulic cylinder 11 is contracted, the upper locking portion 8 rotates clockwise and the lower locking portion 8 rotates counterclockwise in the figure. However, it can be stored in the load support 6.

A cutout portion 16 is formed in a side surface portion of the load support tool 6 so that it can be prevented from interfering with the rotation of the locking portion 8. In addition, in this example, the locking portions 8 are illustrated as being rotatable in opposite directions, but it is of course possible to configure them so as to rotate in the same direction.

The low lift 1 configured as described above, when carrying a cargo car having a small width and a small depth, in a state in which the locking portion 8 is housed in the load support 6 as shown in FIG. , The car is located between the left and right load supports 6.

Thereafter, as schematically shown in FIG. 4, the piston rod 12 of the hydraulic cylinder 11 is extended to position the locking portions 8 so that they can face each other inward, and as shown in FIG. The support 6 is raised. As a result, the cargo vehicle A is picked up by the four locking portions 8 and can be transported by the low lift 1.

Needless to say, when the width and the depth of the cargo vehicle are large, the cargo can be picked up by the load support 6 as in the conventional case. Although described in detail above, the present invention is not limited to the above embodiments, and various modifications can be made without departing from the scope of the present invention. For example, a motor and a chain can be used as means for rotating the locking portion 8. Of course, it is possible to use gears such as gears, belts, etc. In addition, although the locking portion 8 can be housed in the load supporting tool 6 in this example, the locking portion 8 is not limited to this and may be provided on the upper surface of the load supporting tool 6.

[0018]

EFFECTS OF THE INVENTION As a result of adopting the above-described configuration, the present invention allows a cargo vehicle having a small width and depth to be carried by using the low lift 1, and also a cargo vehicle having a large width and depth can be carried out conventionally. The workability is improved because cargo handling can be performed in the same manner as.
