[Industrial applications]

 The present invention relates to a chain hoisting type parking machine capable of reliably preventing the hoisting chain from being wound into a hoisting sprocket wheel.

[Prior art]

 2. Description of the Related Art Conventionally, as a chain hoisting type parking machine of this type, an elevating body having a parking pallet at a required stage is arranged in a fixed frame having a substantially rectangular shape, and the elevating body is a normal body. It is widely known that a hoisting sprocket wheel, which can be driven in reverse, hangs the hoisting chain on a hoisting sprocket wheel and has a required length. By the way, the lifting chain suspended on the hoisting sprocket wheel to raise and lower the lifting body is such that the release side of the suspension portion is always positioned in a hanging state. For this reason, when the lifting / lowering body is moved up and down, the release side part of the lifting chain easily winds around the hoisting sprocket wheel, and is often not released but caught in the hoisting chain. It was very dangerous because it caused cutting accidents and damage to other devices.

As a means for solving the problems in the conventional chain hoisting type parking machine, a vertically long plate that constantly guides the release side of the hoisting chain downward is provided close to the hoisting sprocket wheel. The one provided is disclosed (see Japanese Utility Model Publication No. Sho 63-28282).

[0004]

[Problems to be solved by the device]

 However, in the conventional example configured as described above, the release side of the lifting chain is merely slid along the vertically long plate and guided downward, so that the release side of the lifting chain is It was always in an unstable hanging state, and in some cases, it could get caught in the hoisting sprocket wheel, which was not always satisfactory.

The present invention solves all the conventional problems and provides a chain hoisting type parking machine capable of reliably preventing the hoisting chain from being wound around the hoisting sprocket wheel. Is what you are trying to do.

[0006]

[Means for Solving the Problems]

 That is, according to the present invention, an elevating body 3 provided with parking pallets 4 and 5 at a required stage is disposed in a fixed frame 1, and the elevating body 3 is suspended on a hoisting sprocket wheel 9 which can be driven forward and backward. In a chain hoisting type parking machine that can be raised and lowered by a raised lifting chain 10, guide the inner surfaces of the lifting side 12 and the releasing side 11 in the suspension part of the lifting chain 10 by aligning them with a cam. Therefore, the sprocket wheel-shaped entanglement preventing rotating bodies 14 and 24 are provided in the vicinity of the winding sprocket wheel 9.

[0007]

[Action]

 The entanglement prevention rotating bodies 14 and 24 are fitted to the inner surfaces of the lifting side 12 and the releasing side 11 in the suspension portion of the lifting chain 10, respectively, and are rotated in association with the lifting operation of the lifting chain 10. At the same time, by guiding the part on the release side 11 downward, the winding on the winding sprocket wheel 9 can be reliably prevented.

[0008]

【Example】

 An embodiment of the present invention shown in the drawings will be described below. Reference numeral 1 is a rectangular fixed frame installed in the pit 2, 3 is an elevating body arranged in the fixed frame 1, and 4 and 5 are formed above and below the elevating body 3, respectively. In the upper parking pallet and the lower parking pallet, the elevating / lowering body 3 is a pair of balance chains (not shown) arranged oppositely on both sides of the fixed frame 1 in the longitudinal direction, which will be described later. Immediately both ends are lifted and lowered by a pair of lifting chains 10. 6 is a drive shaft horizontally arranged at the upper end of the fixed frame 1 along the longitudinal direction, and 7 is a forward / reverse rotation connected to one end of the drive shaft 6 via a chain transmission mechanism 8. A free motor, 9 is a pair of winding sprocket wheels mounted on the drive shaft 6 at a predetermined interval, and 10 is a required length suspended around each winding sprocket wheel 9 in a winding shape. Of the lifting chain 10, the release side 11 end of the suspension part of the lifting chain 10 is fixed to the fixed frame 1 in a suspended state, and the lifting side 12 is for guiding the lower end of the lifting body 3. After being wound around the sprocket wheel 13, its end is fixed to the fixed frame 1. Reference numeral 14 is a rotator for preventing entanglement which is automatically disposed under the winding sprocket wheels 9 with a slight clearance, and 15 is a mounting shaft of the rotator 14 for preventing entanglement. The winding prevention rotating body 14 is formed in substantially the same shape as the winding sprocket wheel 9, and is configured to be fitted to the inner surfaces of the lifting side 12 and the releasing side 11 in the suspension portion of the lifting chain 10, respectively. I'm standing. In addition, 16 is a chain retainer of the lifting chain 10, and A is an automobile.

In the embodiment configured as described above, the elevating body 3 is appropriately moved up and down along the fixed frame 1, the automobile A is parked on the upper and lower parking pallets 4 and 5, and the parking is performed. To release. That is, for example, when elevating the lifting / lowering body 3, the winding sprocket wheel 9 is driven in a predetermined direction via the drive shaft 6 by the normal rotation start of the motor 7. Then, the hoisting chain 10 suspended on the hoisting sprocket wheel 9 is gradually hoisted, and together with the equilibrium chain (not shown), the lifting / lowering body 3 is held in the equilibrium state and continuously lifted. At this time, in the suspension portion of the lifting chain 10, the entanglement prevention rotating body 14 which is fitted to the inner surfaces of the lifting side 12 and the releasing side 11 is rotated in association with the operation of the lifting chain 10. However, the hanging side 11 part in the hanging state can be guided downward to reliably prevent the hoisting chain 10 from being wound into the hoisting sprocket wheel 9. Then, when the lifting / lowering body 3 reaches the top dead center, the motor 7 is stopped and the required parking work is performed. When the parking work is completed, the motor 7 is reversely driven to drive the hoisting sprocket wheel 9 in the reverse direction via the drive shaft 6, and the hoisting chain 10 is rewound to lower the lifting body 3. It is good to be busy.

FIG. 5 and FIG. 6 show another embodiment, in which the entanglement preventive rotor 24 forms a tooth profile which can be freely fitted between adjacent link plates constituting the lifting chain 10. The configuration is different from that of the above-described embodiment, other parts are the same, and the same reference numerals indicate the same parts.

The shape of the entanglement prevention rotating bodies 14 and 24 is not limited to the above-mentioned embodiment, and tooth-shaped ones similar to these can be adopted.

[0012]

[Effect of device]

 Since the present invention is configured as described above, the entanglement preventing rotating bodies 14 and 24 are fitted to the inner surfaces of the lifting side 12 and the releasing side 11 in the suspension portion of the lifting chain 10, respectively, to lift the chain 10. It is possible to guide the release side 11 part downward while rotating it in conjunction with the hoisting operation of the hoisting gear, and always reliably to prevent the hoisting chain 10 from being wound into the hoisting rocket wheel 9. It is something that can be done.
