Description

Auger crane for winding wire

The present invention relates to an auger crane, and more particularly to an auger crane capable of pulling or winding wires.

Generally, electric poles support lines such as telegraphs, telephones, electric lights, and the like, such as wooden poles, reinforced concrete poles, and iron poles. In the electric pole, high-voltage and low-voltage distribution lines are often left sick, and this causes the wooden or metal racks to be fixed near the top, and insulators are mounted to support the wires.

In the case of dismantling the electric wire for constructing or connecting the transmission or distribution road between the poles, the end of the electric wire is pulled or constructed by connecting the end of the wire.

On the other hand, in order to recover the waste wire to be dismantled, the waste wire is recovered by the workers and rewound to the reel.

When such work is carried out, the work of pulling or retracting electric wires is performed by hand during the construction or dismantling of power transmission or distribution lines, which requires a relatively large amount of labor and improves productivity due to construction or removal. It is hard to plan.

In view of this point, Korean Utility Model Registration No. 20-0392674 discloses auger crane for winding. The winding auger crane has a coupling portion that can selectively couple the electric pole drilling screw and wire winding machine; It is coupled to the coupling portion, and has a wire-shaped winding machine having a cylindrical drum shape so that the closed wire or reused wire cut to a predetermined length is wound around its periphery.

However, since the auger crane has a structure in which a winding machine is installed perpendicularly to a driving unit for driving a drilling screw, it is inconvenient to separate the screw from the driving unit in order to drive the screw for constructing the electric pole. That is, there is a problem that can not perform auger crane-specific work during the winding operation.

The present invention has been made in view of the above-described problems, and an object thereof is to provide an auger crane winch and an auger crane using the same, which can wind a construction and a closed wire of a transmission line and a distribution line.

Auger crane winch according to the present invention to achieve the above object

Driven by a frame, a drive shaft rotatably installed on the frame, a winding reel bearing supported on the drive shaft and rotatably installed, and hydraulic oil supplied by the hydraulic oil supply means installed on the auger crane, It is characterized in that it comprises a hydraulic motor for rotating the drive shaft, and the clutch means is provided on the rotary shaft and the reel to transmit the rotational force of the drive shaft to the take-up reel.

Here, the drive shaft may be driven by a separate engine installed in the auger crane without being driven by the hydraulic motor. In this case, a reducer may be installed between the engine and the drive shaft.

Alternatively, the auger crane according to the present invention for achieving the above object is

A hydraulic body supply means for driving the screw-driven hydraulic motor driven by the vehicle body, the boom stand provided to the vehicle body, the hydraulic motor installed at the end of the boom stand, the engine mounted on the vehicle body, and the vehicle body. It is installed, driven by a frame, a drive shaft rotatably mounted to the frame, a winding reel bearing supported on the drive shaft and rotatably installed, and driven by the hydraulic oil installed on the frame and supplied by the hydraulic oil supply means. It is characterized in that it comprises a hydraulic motor for rotating the drive shaft, and the clutch means is provided on the rotary shaft and the reel to transmit the rotational force of the drive shaft to the take-up reel.

The clutch means is coupled to the drive shaft by a key installed in the longitudinal direction and is rotated and slidably installed along the drive shaft, the transfer member is formed with a plurality of coupling keys protruding on the outer peripheral surface, the side of the winding reel corresponding to the transfer member And a fastening portion formed with a fastening groove coupled to the engaging key, and a handle for rotatably supporting the transfer member and moving forward and backward along the driving shaft to engage and separate the fastening key and the fastening groove.

The winch installed on the auger crease according to the present invention or the auger crane installed with the winch can perform drilling work and winding and towing work of the electric pole, thereby increasing the operational efficiency of the equipment.

Auger crane according to the present invention can perform the construction of the pole and towing and winding work, an embodiment thereof is shown in Figures 1 and 2.

Referring to the drawings, the auger crane 10 includes a boom stand 12 installed on the vehicle body 11 and itself, a hydraulic motor 13 installed at an end of the boom stand 12, and an engine mounted on the vehicle body. Driven by the hydraulic oil supply means for driving the screw-driven hydraulic motor, installed on the vehicle body 11, a drive shaft 22 rotatably installed on the frame 21 and the frame, and the drive shaft 22 The hydraulic motor 23 for rotating the drive shaft 22 is driven by the winding reel 23 is supported by the bearing rotatably installed and the hydraulic oil supplied to the frame 21 and supplied by the hydraulic oil supply means. And a clutch means 30 installed at the rotation shaft and the take-up reel 23 to transmit the rotational force of the drive shaft 22 to the take-up reel 23.

The clutch means 30 is coupled to the drive shaft 22 by a key installed in the longitudinal direction and is rotated, and is slidably installed along the drive shaft, and a conveying member 32 having a plurality of engagement keys 31 protruding on an outer circumferential surface thereof. And a fastening part 36 having a fastening groove 35 coupled to the coupling key 31 on a side of the winding reel 23 corresponding to the transport member, and rotatably supporting the transport member and supporting the drive shaft. It is provided with a handle 33 for adjoining and separating the coupling key 31 and the fastening groove 32 along the back.

The auger crane configured as described above can tow a wire for power transmission or wiring by using a winch installed in itself. In other words, the rope is installed on its own and transported along the wire trajectory, and then the rope for towing is installed at its end. And drives the hydraulic motor to rotate the drive shaft. In this state, the take-up reel is rotated by operating the handle of the clutch means so that the engaging key and the engaging box are engaged. In this way, the reel is rotated to tow the wire.
