Abstract

PROBLEM TO BE SOLVED: To move an on-vehicle elevator in the vehicle by providing a base and a lift with wheels, and connecting the lift to the base to be elevated. SOLUTION: A base 1 formed by a frame made of metal or the like is a quadrangular box, and a hydraulic cylinder 5 for elevating a lift 2 is provided in the center of the rear end part. The lift 2 is elongated in the longitudinal direction, and has substantially L-shaped side surfaces. Wheels are provided on the front and rear lower end parts of the respective right and left sides of the base 1 and the lift 2, and rails 6 made of metal where the respective wheels 3 run are laid on a load-carrying platform 4. The base 1 and the lift 2 are connected to each other by two links each on the right and left and the hydraulic cylinder 5, whereby when the lift 2 is raised to the maximum, the heights of wheels 3 of the base 1 and the lift 2 are aligned so that it can run along the rails 6. When the lift can be moved in the vehicle, it can be stored at the deepest part of the interior of the vehicle during non-use.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an in-vehicle elevating device installed in a vehicle such as a fire truck and other various types of transport vehicles.

[0002]

2. Description of the Related Art Conventionally, there has been used an on-vehicle elevating device which is provided with a lift which can be moved up and down so that objects placed on the lift can be easily loaded and unloaded.

[0003] However, since the conventional on-vehicle lifting device is fixed to the vehicle body, it cannot be moved inside the vehicle.
Sometimes it was in the way.

[0004]

SUMMARY OF THE INVENTION Therefore, the present invention
It is an object of the present invention to provide an on-vehicle elevating device movable in a vehicle.

[0005]

In order to solve the above-mentioned problems, the present invention employs the following technical means.

The in-vehicle elevating device according to the present invention is an in-vehicle elevating device in which a lift 2 is connected to a base 1 so as to be able to move up and down. It is possible.

The lift 2 may be moved up and down by a hydraulic cylinder 5 provided on the base 1.

[0008]

An embodiment of the present invention will be described below with reference to the drawings.

The in-vehicle elevating device according to the present invention is an in-vehicle elevating device in which a lift 2 is connected to a base 1 so as to be able to move up and down. It was made possible.

FIGS. 1 and 2 are views showing the on-vehicle elevating device, and FIGS. 3 and 4 are views showing the inside of a vehicle on which the on-vehicle elevating device is installed. The in-vehicle elevating device can be installed, for example, in a storage section (not shown) of various fire-fighting equipment provided on the bed 4 of a fire truck.

This on-vehicle elevating device comprises a base 1 and a lift 2 which are constituted by a frame made of metal or the like. Base 1
Has a hydraulic box 5 for raising and lowering the lift 2 at the center of its rear end (right end in FIG. 1). The size of the base 1 can be reduced by employing a small and lightweight hydraulic cylinder 5 as a power source for lifting and lowering the lift 2. The lift 2 has a substantially L-shaped side surface that is long in the front-rear direction (the left-right direction in FIG. 1).

Wheels 3 are provided at the front and rear lower ends of the left and right sides of the base 1 and the lift 2, respectively. And, on the bed 4 of the fire engine, a metal rail 6 for running the respective wheels 3 is laid. The rail 6 has a substantially U-shaped cross section, and the wheel 3 is accommodated inside.

The base 1 and the lift 2 are connected by a hydraulic cylinder 5 to two links 7 on the left and right respectively. The link 7 has one end pivotally attached to the front lower end of the base 1 and the other end pivotally attached to the front upper end of the lift 2.

The hydraulic cylinder 5 allows the actuator 8 to move out and in from the lower end. The hydraulic cylinder 5
The top is pivotally attached to the rear upper end of the base 1, and the tip of the actuator 8 is pivotally attached to the front lower end of the lift 2.

When the lift 2 is raised to the maximum, the height of the base 1 and each wheel 3 of the lift 2 coincide with each other as shown in FIG. Like that.

On the lift 2, for example, a portable water supply pump can be mounted. In this case, as shown in FIG. 3, the on-vehicle elevating device is positioned at the entrance of the storage section at the rear end of the fire truck,
By lowering the lift 2, it is easy for a person working on the ground to load and unload the water supply pump, and it is possible to quickly respond to fire extinguishing activities.

As shown by the solid and broken lines in FIG.
This in-vehicle elevating device can be moved inside the storage section of the fire truck, so that when the water supply pump is not used, it can be stored in the interior of the storage section of the fire truck, which is convenient.

The on-vehicle elevating device can be installed not only on a fire truck but also on various transport vehicles.

[0019]

The on-vehicle elevating device according to the present invention has the above-described structure and can be moved inside the vehicle, so that it can be stored in the interior of the vehicle when not in use. , Convenient.
