Description

[Detailed explanation of the idea] The present invention relates to an improvement of a hanger for a cable crane.

Generally, in cable cranes, hangers are essential to prevent hoisting cables and traversing cables from sagging and to support them at regular intervals so that empty hoist hooks can descend under their own weight.

It is most effective to move this hanger as the carrier moves.

Therefore, as shown in Fig. 1 and Fig. 2,
The friction wheel d is in contact with the hanger drive cable C, which is passed across the span so as to move as the carrier b moves horizontally, and the friction wheel d is driven by the movement of the hanger drive cable C, and the driving force is transferred to the main rope e. It consisted of a sprocket g and a roller chain h that moved the hanger a by transmitting power to the upper drive wheel f.

Note that i is a hoisting cable and j is a transverse cable. However, in such a hanger a, it is necessary to pass a large diameter drive cable C exclusively for hanger a over a long span and multiple water hooks, which requires a great deal of labor. Since the hanger a depends on friction with the carrier f, there was a problem in that if the span had an inclination, the hanger a would not move in synchronization with the carrier b.

The present invention was developed in view of the above-mentioned circumstances, and includes a traveling frame that can run on the main rope of a cable crane, a hanger frame that is suspended and supported by the traveling frame, and a hanger frame that is installed at an appropriate position on the hanger frame. is a spring-type reel equipped with a connecting cable that is fed out to one side of the traveling frame in the running direction; and a spring-type reel that is provided at an appropriate position on the hanger frame and is connected to a connecting cable located on the other side of the traveling frame in the running direction. The hanger frame is characterized by comprising a guide frame provided with a connecting part and a guide roller attached to the lower part of the hanger frame for supporting the hoisting cable and the traversing cable of the cable crane carrier.

Embodiments of the present invention will be described below with reference to the drawings.

FIG. 3 is a schematic diagram showing the entire cable crane equipped with the hanger 1 of the present invention, where 2 is a main rope stretched between struts 3 and 3, and 4 is a cable crane that can run horizontally on the main rope 2. 5 is a hoisting cable of the carrier 4, and 6 is a transverse cable of the carrier 4.

As shown in detail in FIGS. 4 and 5, the hanger 1 includes a running frame 8 equipped with running wheels 7 that can run on the main rope 2, and a hanging frame 8 supported by a pin 9 from the running frame 8. The hanger frame 10 has a hanger frame 10 and an idler roller 1 for the hoisting rope 5 attached to the lower part of the hanger frame 10.
1, a guide 12 for the transverse cable 6 attached to the lower end of the hanger frame 10, a mesh wire 13 for connecting to another hanger 1, etc. adjacent to one side to maintain a distance, and the mesh wire 13 A spring-type reel 14 is provided in the middle of the hanger frame 10 to apply tension (winding force) to the wire 13 so that it always has no slack, and a spring-type reel 14 is installed at one end of the wire from another hanger 1 adjacent to the other side. A socket 15 for connecting the messenger wire 13 is provided, and a buffer 16 for buffering contact between the hangers 1 and 1 is provided at the other end, and the messenger wire 13 fed out from the reel 14 is passed through the buffer 16. The hanger frame 1 has a hole in the middle part.
0 and a guide frame 17 pivotally mounted at an appropriate position.

A required number of hangers 1 having the above structure are arranged on the left and right sides of the carrier 4, and each traveling wheel 7 is engaged with the main rope 2. At the same time, the mesh wire 13 of each hanger 1 is fed out from the reel 14 to open the hole in the buffer 16. Penetrate the buffer 16
It is connected to the guide frame 17 of the non-ringer 1 adjacent to the side by a socket 15.

The end of the mesh wire 13 in the hanger 1 located at the right end in FIG.
At the same time, the hanger 1 located immediately to the right of the carrier 4 is appropriately connected to the carrier 4, and the end of the messenger wire 13 on the hanger 1 located immediately to the left of the carrier 4 is fixed to the carrier 4, Furthermore, the hanger 1 located at the left end is appropriately fixed to the left column 3.

Each hanger 1 is set so that it has a predetermined support pitch when the mesh wire 13 is in its most extended state.

Further, a winding cable 5 is connected to the guide roller 11 of each hanger 1, and a traversing cable 6 is connected to the guide roller 12 of each hanger 1.

In the state shown in FIG. 3, which has been set in this manner, for example, when the carrier 4 is moved sideways to the right, the messenger wire 13 of the hanger 1 located immediately to the left of the carrier 4 is let out from the reel 14. It stretches.

When the messenger wire 13 is fully extended in this way, a predetermined support pitch is established between the hanger 1 and the carrier 4.

If the carrier 4 continues to move, the hanger 1
The messenger wire 13 of the adjacent hanger 1 is further stretched sequentially, and the messenger wire 13 of the adjacent hanger 1 is further stretched to provide a predetermined support pitch between the hangers 1.1.

In this way, when the carrier 4 traverses to the right end in FIG.
All the hoisting cables 5 and the traversing cables 6 located therebetween are supported by each hanger 1 at a predetermined support pitch without sagging.

On the other hand, the mesh wire 13 of each hanger 1 located to the right of the carrier 4 in FIG.
Since the hangers 4 are spring-type, when the distance between the hangers 1 and 1 is reduced, the surplus is automatically wound onto the reel 14 one after another, so that there is no slack.

When the hangers 1 converge, the hangers 1 and 1 come into contact with each other, but since each hanger 1 is provided with a buffer 16 at one end of the guide frame 17, the shock at the time of contact is buffered and it is safe.

Further, even if the carrier 4 is moved laterally to the left, the same effect as described above can be obtained.

It should be noted that the present invention is not limited to the above embodiments, and it goes without saying that various changes can be made without departing from the gist of the present invention.

As described above, according to the present invention, (i) there is no need to run a large-diameter hanger drive cable across a long span as in the past;

(ii) Since the wire for connecting the hangers is automatically wound up using a spring-type reel, there is no risk of the wire hanging down and coming into contact with the ground, trees, etc. even when the hangers are close to each other.

Field The operation is reliable because the hanger can be forcibly expanded and converged.

(iv) The structure is simple.

It can produce excellent effects such as
