2. Description of the Related Art Conventionally, elevators for long-span construction work are mounted on a pair of left and right lifting supports (guide rails, steel towers equipped with racks, etc.) which are installed at required intervals, and both ends of which are attached by movable lifting frames. A long loading platform is erected while being supported by the section, and a drive machine attached to the lifting frame drives a gear that meshes with a rack attached to the lifting support to move up and down. The elevating frame that is driven up and down by these driving machines is driven at the same speed on the left and right, so that the long loading platform installed between the left and right elevating frames can be elevated and lowered horizontally. Since it is necessary to tune the elevating frame, a tuning shaft is arranged between the elevating frames so that both driving machines can be controlled mutually.

In the construction elevator having such a structure, it is difficult to vertically install the elevators so that the dimensions between the elevator supports that guide and support the left and right elevator frames are accurately adjusted. The long cargo bed installed between the lifting frames is supported so that it can be lifted and lowered while being adjusted in its length direction. Therefore, the tuning shaft, which connects the drive parts of both the elevating frames, must naturally have a connecting part having a structure capable of freely adjusting the expansion and contraction in the length direction. For this reason, it is inevitable that the overall structure becomes complicated. In addition, it is inevitable that the self-weight increases and the power of the driving machine also increases. Therefore, this is inconvenient in the case of a lightweight elevator having a relatively small load.

In the embodiment thus configured, when the carrier 1 is being lifted, for example, when the left drive unit 7 is delayed (indicated by a chain line in FIG. 5), the drive unit controller 21 attached to the right elevating frame is moved. The roller 23 at the tip of the operation lever 22 comes into contact with the corresponding operation bracket 25A attached to the loading platform 5 and is pushed down to operate. Then, the excited relay R2 operates the left tilt detection relay LT loading platform 5 as described above, the contact R 2 in the right driving motor MR2 driving operation circuit is de-energized off, the left driving motor MR1 only continued operation, modification time limit timer T of operation of the contact T in correction command circuit to lapse of a predetermined time period 'is cut off the excitation of the relay R2 is off, the relay contact R 2 are turned off at the same time As a result, the self-holding is canceled, and in this state, the loading platform 5 is returned to the horizontal state, and the left and right drive motors M
R1 and MR2 operate normally and the ascending operation is continued.
When a delay occurs in the right-side drive machine 7, the operation bracket 2 in which the roller 23 at the tip of the operation lever 22 of the drive machine controller 21 attached to the left-side lifting frame is attached to the corresponding platform 5
5A is contacted, and as described above, only the driving machine on the opposite side is driven to restore the loading platform 5 to the horizontal state.

The operation of correcting the inclination of the loading platform 5 due to the displacement of the left and right lifting frames 3 and 3 during the lifting operation of the carrier 1 is based on the horizontal position in the vicinity of the connecting portion between the lifting frames 3 and 3 and the loading platform 5. Since the drive controller 21 is operated as described above, it is possible to accurately detect the inclination of the loading platform 5 (cage) and quickly correct it.
The drive unit can be operated safely without providing a mechanism for left-right synchronization. As the drive controller 21, a photoelectric switch may be used instead of the lever type (mechanical type) described above, and a blocking plate may be used as the operation bracket 25 thereof. Further, it is also possible to dispose the drive controller 21 and the operation bracket 25 (25A) in the opposite mounted state.

As described above, according to the present invention, the loading platform of the carrier directly detects the inclination of the moving speed difference between the left and right elevating frames when moving up and down, and moves only the drive unit on the delay side. By driving in the vertical direction and moving the elevating frame to the normal posture, it is possible to operate while correcting tilt even during operation, and it is possible to simplify the device because it can be configured without incorporating a complicated mechanism. .
