[0001]

BACKGROUND OF THE INVENTION This invention relates to a safety device of the elevator device, and more particularly, for example, of the lifting device the safety of the lifting operation of the movable floor and so capable of further improving the multilevel parking systems such as Related to safety devices.

[0002]

2. Description of the Related Art Conventionally, there are various types of lifting / lowering devices, for example, simple two- and three-stage multi-story parking devices.
"A pillar is erected at a corner or end of a movable floor for mounting a vehicle, the movable floor is held horizontally by the pillar, and a chain block is fixed to the movable floor. A structure in which it is moved up and down along the support column via a pulley provided at the top.

In this elevating device, after a vehicle is mounted on a movable floor for mounting a vehicle, a movable floor operation switch is operated to drive a chain block for suspending the movable floor via a pulley. By moving it up and down and stopping it when it reaches a predetermined position, it is possible to park on a plurality of floors including the movable floor and the floor surface.

By the way, this type of lifting device is mounted on a movable floor.
Since a mounted object such as a vehicle is placed on the movable floor and the movable floor is moved up and down, various safety devices are provided. In general, the strut and the movable floor are engaged with each other by an engagement tool formed by a hook and a hook hook, and the movable floor cannot be moved up and down unless the engaged state is released. ing.

[0005]

However, in the case of the above-described safety device in the elevating device, the structure is such that the column and the movable floor are engaged with each other by a hook and a hook hook. Although safety can be ensured, there is a problem that the operation is difficult due to the necessity of trouble and the need to separately operate the parking device operation switch, which is required for the release.

SUMMARY OF THE INVENTION The present invention has been made in view of the above problems, and has as its object the object of the present invention is to provide a safety device for a lifting device having a simple structure and having both safety and operability. It is to provide a device.

[0007]

According to the present invention, there is provided a safety device for a lifting device according to the present invention, in which a support is provided at a corner or an end of a movable floor for mounting an object. Standing up, the movable floor is held on a support via a connecting body, and a connecting tool such as a chain is fixed to the movable floor, and the connecting tool is connected via a pulley or a winch provided on an upper portion of the support, and In an elevating device adapted to move up and down along a column, a hook is provided on the connecting body , and the column is rocked.
A hook operation lever is movably provided, and the hook operation lever is provided.
A part of the bar is engaged with a hook hook of the connecting body to
A hook for restricting the vertical movement of the body is provided , and a lift operating switch is provided on the hook operating lever.

According to another aspect of the present invention, in the safety device for a lifting device according to the invention, the hook operating lever is tiltable with respect to the column with the upper end of the lever as a fulcrum, and the hook operating lever is pulled. In this state, the power supply for vertical movement of the movable floor can be turned on in a tilted state.

[0009]

The safety device for a lifting device according to the present invention has a hook for connecting a movable floor and a column and moving the movable floor up and down along the column. In addition, on the support ,
Operate the hook that engages the hook hook provided
A hook operating lever is swingably mounted , and the hook operating lever is provided with a lifting device operating switch. Therefore, by operating the hook operating lever, the hook can be released from the hooking, after the release, 該Fu
The movable floor can be moved up and down via the connecting body by operating the lifting / lowering device operation switch of the lever for lever operation, and the operability can be improved while ensuring its safety.

Further, the hook operating lever can be tilted with respect to the support column with the upper end of the lever as a fulcrum, and the power for vertical movement operation of the movable floor is turned on with the hook operating lever pulled and tilted. In the case of the configuration in which the movable floor can be moved, the movable floor does not move up and down even if the lifting / lowering device operation switch is operated because the power for the up / down operation is not turned on unless the hook operating lever is pulled to the tilted state. It works to ensure the double security of not doing so.
