Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a truck capable of lifting and transporting a heavy object placed on a sleeper by itself.

[0002]

2. Description of the Related Art Conventionally, when a heavy object placed on the floor through a sleeper, such as a laminated lightweight cellular concrete panel (hereinafter referred to as an ALC panel) is directly lifted from the bottom and conveyed, a forklift or a crane is used. In a place where can not be used, first, insert the lift device between the ALC panel and the sleeper, lift the ALC panel once to remove the sleeper, then insert the dolly and place the transported object on this dolly. It was intended to be transported. Further, in this trolley, not all of the wheel bearing portions are rotatable, but the trolley is formed so as to be movable only in the front-rear direction.

[0003]

However, in this conventional device, the lift device and the carriage are separate,
When loading an ALC panel or the like on a dolly or when unloading at a destination, a lift device is always required, and at a construction site, etc., the lift device must be brought in every time the working floor changes, which is very troublesome. There was a problem that work efficiency was also poor. Also, since the dolly can only move forward and backward,
There is a problem in that there is no freedom in loading the LC panels, and when loading in a horizontally long shape due to the loading destination, it may not be possible to pass through a narrow frontage, and the insertion direction of the lift device is also restricted. Further, since the trolley is formed so as to be transported by one unit, there is a problem that the trolley for transporting a wide range of ALC panels and the like has a large shape and is difficult to handle.

The present invention has been made to solve the above-mentioned conventional problems, and its purpose is to:
The heavy goods placed on the sleepers can be received and transported from the sleepers only by the trolley, and can be transported in any direction regardless of the position of the trolley,
An object of the present invention is to provide a truck with a lifter capable of carrying a wide range of objects on a small mounting surface.

[0005]

[Means for Solving the Problems] As means for achieving the above object, in a trolley with a lifter according to claim 1 of the present invention, a base having an upper surface serving as a mounting surface of a transported object; a bearing for a transportation wheel A transporting unit whose part is pivotally supported by the base so that the base can be moved in any direction; a horizontal shaft is fixed to the lower surface of the base, and a pair of rotating arms rotates the tip end part to the horizontal shaft. Lifting wheels, which are rotatably supported and are respectively supported at the rear ends thereof, are arranged on the front end edge side of the base, and the front end portion of the interlocking arm that swings the rotating arm is pivotally supported by the rotating arm. And a lift wheel pivotally supported on the rear end of the interlocking arm is arranged on the rear end edge side of the base, and the rear end of the hydraulic jack pivotally supported on a horizontal shaft on the lower surface of the base is rotated. With the arm and interlocking arm open, it is connected to the rear end of the interlocking arm, It has a configuration which comprises a; tread position of the lifting wheel and the lift portion is positioned downward or upward with respect to the tread surface position of the transport wheel by condensation. In the trolley with lifter according to claim 2 of the present invention, a locking portion for contacting a side surface of the conveyed object is erected on a rear end edge of the base, and a distance from the rear end edge to the front end edge. Is formed so as to be shorter than the distance from the end portion to the center position of the conveyed product, and one base is formed so as to hold only one side of the conveyed product, and two sets are provided as one set.

[0006]

In the truck with lift according to claim 1 of the present invention, the hydraulic jack pivotally supported on the lower surface of the base is connected to the rear end of the interlocking arm that swings the rotating arm in the open state. First, by loosening (reducing) the hydraulic jack, the interlocking arm pushes the rotating arm to increase the leg opening angle. For this reason, the lift wheels rise, and the tread position thereof is higher than the tread position of the transport wheels. In this state, the base is inserted into the lower surface of the conveyed object, and this time the hydraulic jack is operated to pull the turning arm with the interlocking arm to reduce the leg opening angle. As a result, the lift wheels are lowered, their tread positions are lower than the tread positions of the transport wheels, and the transported object is lifted. At this time, the sleepers are removed. Then, by loosening the hydraulic jack again, the transport wheel is grounded, and the transport wheel is transported to a predetermined position in this state. In this case, since all the bearings of the transport wheels are formed to be rotatable, they can be transported in any direction. Then, at the destination, it can be placed on the sleeper in a procedure substantially reverse to the above.

Further, in the trolley with lift according to the second aspect of the present invention, since the locking portion is erected at the rear end edge of the base, the locking portion extends from one end until it comes into contact with the side surface of the conveyed object. Insert a dolly with a lift. Similarly, a truck with a lift is also inserted on the other end side of the conveyed product to operate the hydraulic jacks. In this case, the width of the base of the trolley with lift is less than half the length of the conveyed object, but if the conveyed object is a flexible object such as an ALC panel, only the ends of the conveyed object are held on both sides. The lifted carriage can be lifted in this state, and the carriages with lifts at both ends can be integrated depending on the weight of the conveyed goods, so that the conveyed goods can be stably conveyed. Therefore, the lifted carriage can be made very compact because it is sufficient to mount and lift only the end portion of the conveyed product and to carry it up and down.
