2. Description of the Related Art In transporting and handling construction materials in construction work, a handling device as shown in a perspective view of FIG. 7 is provided as a support device for carrying and mounting heavy objects which cannot be handled directly by hand. It has been put to practical use. In this system, a control device 51 is placed on a trolley 50, an articulated arm 52 such as a manipulator or a balance arm is attached to the control device 51, the load at the tip of the arm is detected by a force sensor, and the gripping weight is offset by the arm driving force. As a result, in the movable space of the multi-joint arm 52, even a heavy object can be easily handled by one person, and the manipulator of the multi-joint arm 52 is lightly grasped and moved by a person. Again dolly 50
The operation is generally performed by a push button method using the operation box 53, but wireless operation is also available depending on the application.

However, in such a device, the gripping weight is limited to several hundreds kg due to the mechanical limitation of the multi-joint arm 52, and the number of drive axes is large, so the mechanism of the control device 51 becomes complicated and large. The work cannot be loaded on the dolly 50, or it becomes an unnecessarily large device, and the application range is limited.
In addition, the device becomes expensive. Further, it becomes a work unit within the movable range of the multi-joint arm 52, in which a relatively high-precision work can be performed because it takes a free posture, but if it exceeds the range, preparatory work such as moving the carriage 50 becomes necessary. . Therefore, even if it is possible to perform continuous work while moving little by little like attaching a wallboard in a corridor, it is wasteful to go to the wallboard one by one, and also work on the second floor by lifting objects from the first floor to the second floor. Even if it is necessary, another lifting equipment is required, that is, such a device mainly functions as a load reducing jig in a limited work range, and is used by incorporating it in all work including transportation of goods. The device has not been reached.

It is possible to hold down a space for loading heavy objects on the loading platform, and there is no particular restriction on the working range.Continuous work can be done at any place as long as the carriage passage is secured and it is a manual transportation range. It is an object of the present invention to provide a heavy load handling device capable of performing the above.

In the heavy load handling device of the present invention, since the heavy load is lifted by using the lifting device driven by the lifting motor, there is no restriction of gripping weight unlike the articulated arm, and the heavy load can be moved. Since it also serves as the drive shaft of the truck, it is possible to realize the functions required for work with the minimum number of drive shafts. As a result, an inexpensive device configuration with a wide cargo bed is obtained. Further, the work range is not particularly limited because the carriage itself moves with the worker, and the work can be transferred to another floor as a normal lifting device. Therefore, it can be placed on a trolley, moved to a work area, and can be continuously worked while mounting the materials of the loading platform one by one at a predetermined place, and can also be applied to the operation of collectively lifting a plurality of materials on the first floor to the second floor.

When the work is performed outside the loading platform 2 by the above control method, there is no particular problem even if the rotation of the arm 5-2 and the movement of the trolley 1 are performed in parallel, but the loading and unloading of the loading on the loading platform 2 is not a problem. In order to prevent the entire trolley 1 from moving sometimes and hindering the work, as shown in FIG. 6, the length L of the arm 5-2 and the trolley 1
In the rotation angle θ 0 of the arm 5-2, which is determined by the work width W 0 of the loading platform that is the width Wi of the work passage W, an interlock is provided in the operation management circuit 303 so as to prohibit the operation of the carriage 1. . Loading and unloading on the loading platform 2 is limited to lifting and unloading work in the vicinity of the rotation arc of the arm 5-2, and it is not possible to cover the entire loading platform 2; If a simple lateral movement jig is prepared, the practical function can be sufficiently achieved.

Although the posture of the carriage 1 may change due to variations in road surface resistance of the caster wheels 3 during movement of the carriage, the movement speed in the "load handling" mode is slow, and even if the posture changes a little, there is no problem in actual work. . If the posture changes significantly, correct it in "Move" mode. When an operating force is applied in the vertical direction, the load of the suspended load + operating force is detected by the load detecting force sensor 22. When the load switch mode is set by the changeover switch 231, the load detection force sensor 22 to the load detection force sensor 22 to the load load signal stored in the wire load reference signal setting circuit 307 as a reference value.
The subtraction circuit 306 calculates the difference from the actual load value of the wire load detection circuit 305, sets the direction in which this difference becomes zero and the speed proportional to the difference, and raises and lowers it via the operation management circuit 303 and the servo driver 310. The servo motor 223 is driven to move up and down.

During the "load handling" work, the actual load value is constantly monitored by the wire load reference signal setting circuit 307, and the work situation when landing the suspended load, lifting it, or applying an operating force is actually measured. Judgment is made based on the difference in the rate of change of load, and the reference value is updated based on the result. In other words, the rate of change in operating force is several
While it is kg / sec, the rate of change is several tens of kg / sec when landing or hoisting. By detecting this difference, the above work status is automatically determined. As a result, at the time of landing (lifting), the descending (raising) operation is temporarily stopped, and then the set actual load value is updated as the reference value at the time of landing.
