Description

Description: [Industrial field of application] The present invention relates to a carrier device using a rail traveling type carriage.

[Prior Art] Generally, as a system for transporting materials and equipment,
There is used one in which a rail is laid on a transport path, a trolley that can travel freely is arranged on the rail, and materials and equipment are transported by the trolley.

If there is a large difference in elevation such as a shaft in the above-mentioned transport route,
When vertically transporting materials, equipment and the like, a high place route and a low place route can be connected by an elevating device.

A conventional transport device having a vertical transport path has a first transport path from a transport source to an upper portion of the vertical transport path.
Rails are laid, a second rail is laid on the low-pass route from the lower part of the vertical transport route to the destination, and between the first rail end and the second rail end of the vertical transport route, respectively. A hollow frame having a carry-in / out port is provided at the rail end of, and an elevating and lowering platform is arranged in the hollow frame so as to be vertically movable (these hollow frames and the elevating and lowering platform compose an elevating device),
A third rail that can connect between the first rail end and the second rail end is laid on this lifting platform.
The truck is arranged on the first to third rails.

In the above-mentioned transfer device, first, the materials and equipment are placed on the carriage on the first rail at the transfer source, and this carriage is moved on the first rail on the high-altitude route from the transfer source to the high-altitude entrance / exit of the hollow frame. To move. Next, the hoisting platform in the hollow frame is stopped at the high-level loading / unloading port, and the third rail on the hoisting platform is connected to the first rail on the highway route. Next, the carriage is moved from above the first rail to above the third rail at the high-port loading / unloading entrance, and stopped on the third rail. next,
The trolley on the third rail is moved down to the low-place loading / unloading port by the lifting platform, and the third rail is connected to the second rail on the low-level route at the low-level loading / unloading port. Next, the carriage is moved from the third rail to the second rail, and the second rail is sent to the destination. On the contrary, the dolly is sent from the low place transportation source to the high place transportation destination.

Conventionally, the lifting device used in the above-mentioned transfer device is provided with a winch at the upper part of a tower or a building, and a lifting platform with a load placed inside the tower or the building is hung by a wire from the winch, and the winch lifts the platform. It moves up and down along the guide rails.

[Problems to be Solved by the Invention] By the way, in a carrying device having the above-mentioned lifting device,
Since the hoisting platform vibrates when the hoisting platform is moved up and down along the guide rails, it is necessary to provide a space between the hoisting platform and adjacent structures other than the guide rails to absorb the amount of shaking. Therefore, even when the lifting platform is stopped at the carry-in / out port, a gap is generated between the third rail end and the first or second rail end. As a result, in the above-described transport device, there is a problem in that the carriage vibrates when the carriage moves through the above-mentioned gap, which hinders smooth traveling, resulting in damage to the load of the carriage.

The present invention has been made in view of the above circumstances, and an object of the present invention is to provide a carrier device using a rail traveling type carriage that allows smooth traveling of the carriage without hindering the lifting of the lifting platform. is there.

[Means for Solving the Problems] A conveyor using a rail traveling carriage of the present invention conveys materials to a conveyor path provided with a vertical conveyor path having a height difference in the middle of the horizontal conveyor path. The first transport rail is laid on the high-altitude transport path so that one end faces the upper part of the vertical transport path, and the first rail faces the low-altitude transport path so that one end faces the lower part of the vertical transport path. A second rail is laid on the hollow frame, and a vertical frame is provided with a hollow frame having an upper end facing one end of the first rail and a lower end facing one end of the second rail. An elevator platform is arranged inside the elevator so that a third rail is laid on the elevator platform, and a carriage that can travel on the first, second, and third rails is disposed, and the first or the first rail is installed. Transfer of the trolley between the second rail and the third rail In the transfer device, the carriage is moved from the first rail to the second rail or from the second rail to the first rail by moving up and down the lifting platform.
Of the rail is connected to the first or second rail, the connection end is separated from the other portion, and the tip of the connection end of the third rail is connected to the first or second rail. The first frame and the second frame are pivotally supported so as to be rotatable in a direction away from the possible position with respect to the hollow frame.
Of the rail, the connection end connecting to the third rail is separated from the other portion, and the first and second connection ends are connected from the position where their tips can be connected to the third rail. It is pivotally supported so as to be rotatable in a direction away from the lifting platform.

[Operation] According to the above configuration, when the trolley moves across the first or second rail and the third rail, the rotatably pivotally supported rail end portion is moved to the above-mentioned first or second rail end portion. By arranging the first or second rail and the third rail so as to connect to each other and forming a straight line and connecting the rails without a gap, smooth traveling of the trolley can be achieved. Also, when raising and lowering the lifting platform,
An interval that absorbs vibration when the hoisting platform moves up and down between the hoisting platform and the hollow frame other than the guide rails by rotating the rail end and retracting it inside the hoisting platform or to the loading / unloading port side of the hollow frame. By providing the above, the vertical movement of the lifting platform is not hindered.
