Description

Cable Hanger Apparatus

The present invention relates to a cable hanger device configured to smoothly move a cable for supplying power to a ceiling crane or the like.

A cable hanger is a device for moving a cable that supplies power to a remote device.

Conventional cable hangers are configured to move along the I-beam. For example, a pulley of a conventional cable hanger is engaged with an I-beam and moves in one direction. However, since the cable hanger having such a structure transmits the impact applied to the I-shaped steel as it is to the cable hanger, not only the cable hanger derails easily but also a safety accident due to derailment of the cable hanger can occur. In addition, since the conventional cable hanger is configured to move along the straight I-shaped steel, it is difficult to change the moving range in various ways.

Therefore, it is necessary to develop a technique for preventing derailment of the cable hanger and providing freedom of movement of the cable hanger.

For reference, Patent Documents 1 and 2 are the prior art related to the present invention.

The pulley 110 is configured to smoothly roll along the wire 200. For example, the diameter of the groove formed in the pulley 110 may be larger than the diameter of the wire 200. The shape of the pulley 110 enables stable contact between the grooves of the pulley 110 and the wire 200 to enable smooth rolling motion of the pulley 110.

The pulley 110 may be composed of a plurality of pulleys. For example, the pulley 110 may be two. However, the number of pulleys 110 is not limited to two. For example, the number of pulleys 110 may be increased or decreased according to the load applied to the cable hanger 100.

The pulley 110 configured as described above is rotatably installed on the bracket 120 via the connecting shaft 112.

The bracket 120 is configured to support the pulley 110. For example, the bracket 120 may be U-shaped to support both sides of the pulley 110. However, the bracket 120 is not limited to the U-shape. For example, the shape of the bracket 120 can be changed in the shape of a bracket to allow stable support of the dowel 110.

The bracket 120 includes one or more face plates 122. In other words, a plurality of face plates 122 extending in the radial direction of the wire 200 may be formed at the front and rear of the bracket 120. More specifically, the face plate 122 may extend from the bracket 120 in a direction away from the wire 200. The thus formed face plate 122 can provide a space in which other members can be attached or installed without interfering with contact between the pulley 110 and the wire 200. [

The face plate 122 may be formed integrally with the bracket 120. For example, one steel plate may be pressed to produce a shape in which the bracket 120 and the face plate 122 are connected. The face plate 122 may be formed symmetrically on both sides of the bracket 120. In addition, the face plate 122 may be formed in a symmetrical shape on the front surface and the rear surface of the bracket 120. The thus formed face plate 122 can be used as a space for mounting the stopper 150.
