Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a cableway system for horizontal transportation used at a construction site or the like.

[0002]

2. Description of the Related Art Conventionally, a crane or a carrier is often used to horizontally convey materials at a construction site or the like. However, there are cases in which the horizontal transfer means cannot be used due to various restrictions on the moving road surface, such as a basement floor under the floor, a floor reinforcing bar arrangement, or a large load on the floor surface. In such a case, there is a method in which a traveling rail is temporarily installed under a beam, for example, and a trolley is provided on the traveling rail to horizontally convey an object, but this method has the following drawbacks. It takes a lot of time to install and change the running rail. The components are heavy and work upwards, which is dangerous due to heavy labor. High cost. Therefore, it is unsuitable for use in a relatively short period of time, and in the current situation, it is inevitable to carry out transportation work manually on site.

[0003]

As a simpler means than the above-mentioned running rail, there is a method of using a cableway found in forestry and the like, which is a wire rope which is generally a main rope 1 (fixed rope) as shown in FIG. Is laid across the anchor saddle 11 and the heel block 7 with a required span, and an appropriate tension is applied by a tensioning device 8 and a carrage block 3 that traverses using the main rope 1 as a guide is attached. is there. The carriage block 3 is provided with a sheave 4 which fits into the main rope 1 and rolls, and a lifting device 5 is provided below the sheave 4.
The object 6 is lifted up and down, and the traverse operation is performed by pulling it left and right through the traverse rope 2, the traverse capstan drum 9, and the snatch block 10 which are connected to the side portions of the carrage block 3. . However, the cableway having such a configuration has the following problems. When the span is large, the central hanging amount of the main rope is large, and when it is used in a building frame, etc., the lift is small, which is not practical. It is possible to apply a pre-tension to the main ropes to reduce the amount of central droop, but in that case, the tension will be large, so the diameter of the main ropes will be large, and a large holding force is required on the fixed side as well. It becomes difficult, and the installation place is limited due to the relationship with the body, and it will not be possible to easily refill. Therefore, it is an object of the present invention to provide a horizontal transport cableway system which has a small central hanging amount, is easy to handle with a small tension, and has a limited installation place and can be easily refilled. .

[0004]

As a means for technically solving the above-mentioned problems, the present invention relates to a main rope having both ends fixed and laterally suspended in a stretched state, and an appropriate interval between the main ropes. An intermediate support member for supporting and opening a plurality of carriage blocks that are traversably mounted on the main rope, and a connecting beam that connects these carriage blocks through pins at predetermined intervals. The gist of the present invention is to provide a horizontal transport cableway system that includes at least a lifting device that is attached to the connecting beam and that lifts and lowers a transport target. In addition, the carrage block has a sheave that fits into the main rope,
The gist is that the drive device for rotating the sheave is provided to make it self-propelled.

[0005]

[Operation] In the middle of the horizontal span of the main rope, intermediate support members are temporarily installed on the beam above the building at appropriate intervals to support the weight of the main rope and the weight suspended from the main rope. By suspending two carrage blocks having a plurality of sheaves on the main rope, and further connecting them by a connecting beam via a pin, the load applied to the main rope is dispersed. Since each carrage block rotates to some extent with respect to the connecting beam,
When the carrage block gets over the intermediate support member,
By rotating in the direction opposite to the traveling direction, the load can be moved rearward and can pass smoothly.

[0006]
