Description

Detailed Description of the Invention "Field of Industrial Application" This invention is a construction site for a terrestrial housing with a rotating jib, which is installed on the ceiling of a large space structure such as an event hall or a multipurpose stadium, and used for carrying in/out and moving exhibits, etc. It is related to.

"Prior Art" As a crane installed on the ceiling of a structure, an overhead crane, Teruha, etc. are known.

Overhead cranes are mainly installed in factories, etc., and have both ends of a girder mounted on a pair of running paths spaced apart from each other at a high place in the structure, and hoisting and traversing devices are installed on the girder. It is something that

``Problem to be solved by the invention'' However, when installing an overhead crane as described above in a large space structure, a girder with a long span is required, so the equipment becomes large regardless of the load of the cargo to be lifted. Moreover, in order to support such large equipment, the supporting capacity of the structure must be increased, and reinforcement is required. For this reason, such an overhead crane has a large ff1f
When used in a factory or the like where objects need to be moved frequently, heavy objects can be lifted from any point within a large space structure and then moved to any point within the structure (3) and then lowered. However, the equipment costs are high, so if the equipment is used only for transporting and installing comparatively light items such as exhibits, such as in event halls and multipurpose stadiums, was considered excessive.

Additionally, Teruha handles cargo by suspending a hoist from rails laid at high places, but the work area is limited to just below the rails, so the hoisted cargo cannot be placed in any position. There was a problem that alignment was difficult.

The present invention has been made in view of the above circumstances, and an object of the present invention is to provide a Terha with a rotating jib that can cover the entire area inside a large-space structure, is inexpensive, and has a simple configuration.

``Means for Solving the Problems'' The Terha with a swing jib of the present invention includes a rail laid horizontally at the bottom of the ceiling of a structure, and a travel motor that is supported by the rail via a roller and rotates the roller. A traveling bogie equipped with a jib mounting body rotatably supported on the running bogie around a vertical axis, a jib attached to the jib mounting body and extending horizontally, and a tip of the jib. a load block suspended via a rope; a counter jib attached to the jib mounting body and extending in a direction opposite to the jib; A winch for raising and lowering the hanging load block, and a swing motor attached to the jib mounting body and rotating the jib mounting body around a vertical axis to rotate the jib and counter jib. It is something.

"Function" In the Teruha with a swinging jib of the present invention, the crane main body is constructed by rotatably supporting the jib for suspending cargo on a traveling cart running along the rail, so that the jib is long on both sides of the rail. A strip-shaped work area with a width corresponding to the height of the work area is secured, and as a result, the entire area within the Ozora uM structure can be covered with fewer rails. Furthermore, by ensuring a wide working range by rotating the jib, there is no need to provide the crane body with functions such as traversing.
Since the structure is simpler and the crane body is lighter, reinforcement on the structure side can be minimized, resulting in a simple and inexpensive structure for the entire equipment.

When installing cargo in a predetermined position using this rotating jib-equipped Terha, first, the rollers are rotated by activating the travel motor. In this way, the trolley runs along the rails laid on the ceiling of the structure,
The jib attachment body, jib, counter jib, etc. supported by the traveling truck move together with the traveling truck to a location close to the lifting point. Therefore, the operation of the traveling motor is controlled to adjust the stopping position of the traveling bogie, and the swing motor is operated to rotate the jib and counter jib together with the jib mounting body, so that the jib is supported by the tip of the jib. When the suspended load block is positioned above the lifting point, the operation of the travel motor and the swing motor is stopped. After the tip of the jib is stopped above the lifting point in this way, the winch attached to the counter jib is operated to lower the load block, and the load block is moved to the lifting point. The winch operation is stopped when the vehicle has descended to a certain level.

After the load block was lowered to the lifting point in this manner, the load was suspended on the load block, and the winch was activated to wind up the rope, thereby suspending the load. Raise the hanging load block in this condition. After the cargo is raised to a predetermined height in this manner, the operation of the winch is stopped. Then, by activating the traveling motor, the traveling cart is made to travel along the rail, thereby moving the cargo close to a predetermined hanging and unloading point. Therefore, the operation of the travel motor is controlled to adjust the stop position of the travel cart, and the swing motor is also activated, and when the load is accurately located on the lifting point, the travel motor and the swing motor are activated. Avoid stopping. After doing so, the load is lowered by activating the winch, thereby placing the load accurately at the unloading point, and then the winch is deactivated and the load is moved from the load block to the Remove luggage.
