DETAILED DESCRIPTION OF THE INVENTION

[0001]

The present invention relates not relate cableway traveling device, by one of the traverse cord in addition to the main rope that Tsu支the carriage, allow to distinguish between operation of traveling and hoisting rope the carriage It was made.

[0002]

2. Description of the Related Art A cableway or a cable crane is a transport device for suspending a carriage on a single main rope connecting an unloading point and a loading point so as to be able to travel, and lifting and transporting cargo from the carriage. It is.

Conventionally, in this transporting apparatus, as shown in FIG. 15, a carrier 3 is hung from sheaves 2 and 2 which can be placed and rolled on a main rope 1, and one carrier is provided before and after the carrier 3. An end of the transverse rope 4 such as a wire rope is connected, and the transverse rope 4 is endlessly wound around a winch drum 6 at a loading point or a discharging point via a plurality of sheaves 5, and the winch drum 6 is driven by a driving machine 7. To rotate.

A take-up drum 8 is rotatably supported by the carrier 3, and one end of the take-up drum 8 is connected to the take-up drum 8, and a winding rope 9 such as a wire rope is wound through sheaves 10 and 11. At the other end, a weight 12 and a hook 13 are connected. In order to drive the take-up drum 8 forward and reverse, a hoisting sheave 14 is connected to the take-up drum 8, and a hoisting cable 15 such as a wire rope is wound around the take-up sheave 14. It is wound endlessly around a winch drum 17 with a winch drum 16 interposed therebetween, and the winch drum 17 is driven to rotate by a driving machine 18 connected to its shaft.
The winch drum 18 is operably disposed at a carry-in point or a carry-out point.

To lift the cargo hung on the hook 13, the winch drum 17 is driven to rotate by the driving device 18 to move the hoisting cable 15 to the left in the drawing, and the winding sheave 14 is turned counterclockwise. , The winding drum 8 rotates in the same direction, and the hoisting cable 9 rises. On the other hand, conversely, when the hoisting rope 15 is moved rightward in the figure, the winding drum 1
The hoisting cable 9 is extended from 7 and the hook 13 is lowered.

Further, when the transporter 3 is driven, the winch drum 6 is driven to rotate by the driving device 7 to move the traversing rope 4 to the left or right, so that the transporter 3 moves. At this time, since the hoisting sheave 14 rotates, in order to prevent the hoisting rope 9 from being overwound, a clutch (not shown) is interposed between the hoisting sheave 14 and the hoisting drum 8 during traveling. The hoisting sheave 14 can be independently rotated.

[0007]

However, in the above-mentioned conventional transporting apparatus, the transverse cable 4 and the winding cable 1 are provided outside the main cable.
5 is endlessly stretched, and the three routes and their support work are very troublesome. In addition, when the cargo is not hung on the hook 13, the weight of the hoisting rope 15 is smaller. Since the hook 13 becomes heavy, the hook 13 may not be able to descend. Therefore, a rope for forcibly dragging down is added, or a weight 12 having a predetermined weight is connected as shown in the figure.

In order to reduce the trouble of wiring, a type in which an engine is mounted on the carrier 3 has appeared. According to this, the traversing cable 4 is wound around the carrier 3 and self-propelled. Is provided with an independent drive motor that performs running, hoisting, and hoisting respectively, but since the engine is mounted, the motor is mounted outside the fuel tank However, there is a disadvantage that the work efficiency is poor because the weight required for the operation is increased and the lifting capacity is restricted.

In addition, in the case of the engine-mounted type, every time fuel is replenished, the transporter 3 in the air must be lowered to the ground or replenished at a height reaching the transporter 3. This is dangerous and has a disadvantage in terms of safety in maintenance.

Therefore, in view of the above circumstances, the present invention eliminates the distinction between the operation of the traversing line and the hoisting line, and operates with a single traversing line to solve the conventional disadvantages of a new cableway traveling device. I will provide a.

Is fixed to the frame body 32 and the hydraulic cylinder 4
The pressing block 48 which advances and retreats from 5 is provided with springs 47 and 4.
7 facing the main rope 30. Therefore, when pressurized oil is supplied to the hydraulic cylinders 45, 45, the pair of press contact blocks 48, 48 advance to each other to tighten the main rope 30,
When the hydraulic oil is drained from the hydraulic cylinders 45, 45, the main ropes 30 are retracted by the force of the springs 47, 47 in a direction away from each other.
Is released. 46 is the main rope 30
Guide plates provided above and below the press contact block 48 to sandwich

As shown schematically in FIGS. 6 and 7, a brake 50, which is a clamp composed of a hydraulic caliper, is fixed to the frame main body 32 with a disk 49 serving as a flange of the reel-shaped winding drum 34 interposed therebetween. Have been. The equalizer sheave 37 of the hoisting cable 36 is used to uniformly wind the hoisting cable 36 around the winding drum 34,
Are formed in a tapered shape, and have a free slide mechanism so as to form a fleet angle so that the equalizer sheave 37 can swing.

In order to remotely control the brake 50 and the clamp 44, a receiver 52 is mounted on the frame body 32 and a pair of switch devices 53 operated by the receiver 52.
Is mounted on the frame main body 32. The receiver 52 is wired so as to be supplied with power from a battery power supply 54, and the battery power supply 54 is charged from the generator 43. The receiver 52 receives a radio wave from the ground with the antenna 55.

A pair of switch devices 53 are for independently operating the brake 50 and the clamp 44, respectively, and are fixed to the frame main body 32 as shown in FIG. Electric actuator 57, a pair of hydraulic cylinders 64 and lever converter 60
The electric actuator 57 is electrically connected to the battery power supply 54 via the switch 59 to operate the hydraulic cylinder 64 with hydraulic oil.

The electric actuator 57 and the operating rods 62 and 63 of the hydraulic cylinder 64 are connected to a lever converter 60. The lever converter 60 is rotatably supported by the frame main body 32. Reference numeral 61 denotes an oil reservoir tank for storing hydraulic oil of the hydraulic cylinder 64.

As shown in FIG. 9 and subsequent figures, limit switches 66, 67, 68, and 69 for regulating the operation of the electric actuator 57 are provided. These limit switches 66, 67, 68, and 69 are electrically operated actuators. The switch 59 is configured to turn on / off the power supply of the switch 57.

Therefore, the switch device 53 is connected to the clamp 44
And the brake 50 is interlocked, that is, the clamp 44 and the brake 50 are alternately opened and closed.

The operation of the above embodiment will now be described. When the transporter is moved along the main rope 30, the brake 50 is used.
To clamp the disk 49 and release the clamping of the main rope 30 by the clamp 44. That is, the electric actuator 57 is operated by operating the receiver 52 by radio control (wireless), and as shown in FIG.
When the rod 62 of the electric actuator 57 on the side is pulled,
The lever transducer 60 tilts and pushes the rod 63 of the hydraulic cylinder 64, whereby hydraulic oil is supplied to the brake 50, the disk 49 is clamped and fixed, and the winding drum 34 is fixed.
Becomes unable to rotate.

Further, as shown in FIG.
When the electric actuator 57 on the fourth side is operated and the rod 62 of the electric actuator 57 is pushed out, the lever converter 60 tilts and pulls out the rod 63 of the hydraulic cylinder 64, so that the hydraulic oil of the clamp 44 enters the hydraulic cylinder 64. After being sucked, the guide plates 46, 46 are separated from the main rope 30 by the forces of the springs 47, 47, respectively.

When the clamp 44 and the main rope 30 become free, the transporter can move along the main rope 30. Therefore, by moving the transverse rope 33 rightward or leftward with a winch drum as in the conventional case, The carriage can move along it. The pulley 41,
45 rotates, the generator 43 generates power, and the battery power 54
Charge.

Then, when the above-mentioned traveling is stopped and the operation is shifted to the operation of raising and lowering the cargo, as shown in FIG.
The switch 49 on the brake 50 side fixes the disk 49 so that it cannot rotate, and as shown in FIG.
When the electric actuator 57 of the switch device on the clamp 44 side is operated in the reverse of the above-described operation and the rod 62 of the electric actuator 57 is pulled, the lever converter 60 tilts and pushes the rod 63 of the hydraulic cylinder 64 to press the hydraulic oil to the clamp 44. The clamp 44 clamps the main rope 30. Therefore, the carrier is in a state where the main rope 30 cannot move along and the hoisting rope 36 cannot be raised or lowered.

Therefore, when raising and lowering the cargo,
As shown in FIG. 3, the rod 6 of the electric actuator 57
When the lever 2 is pushed out, the lever converter 60 tilts, pulls the rod 63 of the hydraulic cylinder 64, sucks the hydraulic oil from the brake 50, and separates it from the disk 49, so that the disk 49 becomes rotatable.

Then, as shown in FIG.
When the rod 62 of the electric actuator 57 is pulled by operating the electric actuator 57 of the switch device on the fourth side in the opposite direction to the above operation, the lever converter 60 tilts and pushes the rod 63 of the hydraulic cylinder 64 to clamp the hydraulic oil. The clamp 44 clamps the main rope 30. Therefore, the hoist drum 34 is in a rotatable state.

Then, when the transverse cable 33 is rotated to the right,
The hoisting rope 36 descends from the hoisting drum 34, and when the reverse operation is performed, the hoisting rope 36 rises. Thus, the traveling of the transporter and the lifting / lowering operation of the cargo can be performed by one transverse cable 33.

[0029]

According to the present invention described above, the opening and closing operations of the clamp and the brake are performed by the hydraulic cylinder.
The hydraulic cylinder may have a heavy hydraulic weight
Without attaching a raw device,
Hydraulic oil in hydraulic cylinder by increasing force with lever converter
Compressed with a simple hydraulic mechanism and lightweight.
To operate the clamps and brakes
Ideal for Opening and closing operation of the clamp and brake
Since the switch for interlocking is provided, the operation of the clamp and the brake is not erroneously performed, and the operation is reliable and the safety is enhanced.

[0030]

[0031]

Further, since the opening / closing operation of the hydraulic device is wirelessly controlled, it is not necessary to mount the engine on the carrier or supply fuel to the engine, and the battery power of the receiver mounted on the carrier is reduced. Since the generator for charging is installed, the disadvantage that the battery power is consumed and the receiver does not operate can be avoided. If the generator uses the traveling of the carrier to generate power, the traveling time is longer than the cargo handling time, so that the charging time is long and the charging effect is high, and no fuel or the like is required.

Then, the rotation of the winding drum is stopped by a brake, and the clamp for fixing the carrier to the cableway is released. Then, by operating the transverse cable, the carrier travels on the cableway, and the brake is released to release the brake. After the take-up drum was rotated freely, the hoisting rope was moved up and down by operating the traversing rope and rotating the winding drum. Cargo can be raised and lowered.

Further, the apparatus of the present invention can be used up to the capability of the winch, and does not clamp the traverse cable, so that the traverse cable is not damaged and the operation of lowering the hook for catching cargo becomes easy.
