Description

[Detailed Description of the Invention] [Industrial Field of Application] The present invention relates to a traveling device for a hanging tool, and particularly to a traveling device for a hanging tool that is designed to expand the movement range of the hanging tool as much as possible.

[Prior art] In the case of cargo handling equipment such as overhead cranes, a hanging device for suspending cargo runs along the longitudinal direction of a hanging beam having a considerable length that is suspended horizontally from the equipment main body. One that is configured to be movable is known. In this case, the range of movement of the hanging tool is restricted by the length of the hanging beam.

[Problems to be solved by the invention] By the way, if it is possible to extend the traveling distance of the lifting equipment with respect to the hanging beam by changing the configuration of the traveling device of the lifting equipment, it is possible to increase the range of cargo handling work without unnecessarily extending the hanging beam. can be expanded.

As shown in FIG. 4, regarding a wheel d running on a running rail b formed on a suspension beam a while supporting a hanging device c, this wheel d is aligned on the load center W of the hanging device c. If one is provided, the wheel d can be brought closer to the end e of the traveling rail by approximately the wheel radius R. However, in this case, there is a problem that the hanging tool c swings around the wheel d.

On the other hand, if two wheels d are provided sandwiching the load center W of the hanging device c as shown in FIG. As you move further away from the object, your range of movement will become narrower.

Furthermore, in order to eliminate these drawbacks, a central wheel d ₁ is placed on the load center W of the hanging device c as shown in FIG.
, and side wheels d ₂ are provided in front and behind the central wheel d ₁ in the running direction to restrict swinging of the hanging tool c,
At the center of the hanging beam a, the hanging device c travels and moves while being guided by these side wheels d ₂ and supporting the weight of the _load . It is conceivable to extend the running distance of the hanger c by separating it from the running rail b and moving it closer to the rail end e by approximately the center wheel radius R, as in the case of one wheel.

However, in this case, the number of wheels increases, leading to an increase in weight and cost. In addition, if there is an obstacle at the end e of the hanging beam, the side wheel _d2 cannot be removed, and the system could not be adopted.

[Purpose of the invention] The present invention was devised in view of the above-mentioned problems, and its purpose is to provide a traveling device for a hanging device that can extend the traveling distance of the hanging device as much as possible with respect to the entire length of the hanging beam. There is something to do.

[Summary of the invention] The present invention is a device for running a hanging device along the longitudinal direction of a hanging beam. A wheel for supporting the load center of the hanging tool, and a guide member on both sides of the wheel, at least one of which engages with the traveling rail to restrict swinging of the hanging tool, and at the end of the traveling rail, A stopper is provided to stop the wheel at a position where the guide member located in front of the wheel in the running direction is separated from the running rail, and one of the guide members is separated from the end of the running rail to support the load center of the hanging device. This makes it possible to move the wheels as close to the ends of the running rail as possible.

[Embodiment] A preferred embodiment of the present invention will be described below in detail with reference to the accompanying drawings.

As shown in Figures 1 and 2, both ends are pulleys 1.
Hanging beam 3 suspended by wire 2 through
A running rail 4 is provided along its longitudinal direction. This running rail 4 is composed of a pair of channel parts 4a formed at both ends of an H-shaped steel, and at both ends 4b of the running rail 4, the channel parts 4a are open along the longitudinal direction of the rail.

A wheel 5 is engaged with the traveling rail 4 so as to be freely movable, and a hanging tool 7 is suspended from the wheel 5 via a bracket 6. The hanging device 7 is formed with a considerable length along the longitudinal direction of the running rail, and a hook 8 for hanging cargo is provided at the lower part.

The wheels 5 are arranged on the load center W of the hanging device 7 in order to support the weight of the cargo. Further, guide members 9 are provided on both sides of the wheel 5 in the forward and rearward directions of the hanging tool (in the longitudinal direction of the traveling rail).

As shown in FIGS. 1 and 3, these guide members 9 are H
It is formed in a U-shape in cross section, sandwiching the flange portion 4c of the shaped steel from both sides in the width direction, and is disposed on the upper part of the hanging tool 7. These guide members 9 are connected to the wheels 5.
It functions to restrict the swinging of the surrounding hanging tool 7. The load center W of the hanging device is the position where the hook 8 is located and the weight of the load is applied.

On the other hand, stoppers 10 are provided at both ends 4b of the running rail 4 to stop the running of the wheel 5 at a position where the wheel 5 reaches when the guide member 9 located ahead of the wheel 5 in the running direction is separated from the running rail 4.
will be provided. Specifically, the stopper 10 is connected to the channel portion 4 opened at the end portion 4b of the traveling rail 4.
The guide member 9 is made of a plate material or the like that covers the guide member 9 to the extent that it does not prevent the guide member 9 from being removed.

Next, the operation of the embodiment will be described.

As shown in FIG. 1, when the wheel 5 supporting the suspension 7 reaches the end 4b of the running rail,
While the guide member 9 in front of the wheel 5 in the running direction is detached from the running rail 4, the wheel 5 is further run,
The hanging device 7 is moved to a position where the wheel 5 is stopped by the stopper 10. In the illustrated example, it can be approached to a position separated by the wheel radius from the rail end 4b. Therefore, the range of movement of the hanging tool 7 relative to the entire length of the hanging beam 3 can be expanded. Therefore, the range of cargo handling work can be expanded without needlessly extending the hanging beam 3.

Furthermore, since the guide member 9, which has a simple structure, restricts the swinging of the hanging tool 7, the construction can be made at a lower cost and the weight can be reduced compared to the case where wheels are used. Further, by forming the guide member 9 into a flat U-shape, even if there are obstacles at both ends of the rail, it can be avoided.

Further, when the rail end 4b is reached, in addition to the wheels 5, a guide member 9 at the rear in the traveling direction remains on the rail 4 and is engaged with the rail 4, so that swinging of the hanging tool 7 can be restricted.

On the other hand, when running at the center of the rail 4, the wheels 5
The guide member 9 is engaged with the rail 4, and the hanging tool 7 can be moved while controlling its swing.

Furthermore, by providing the stopper 10, it is possible to appropriately stop the hanging tool 7 and prevent it from falling.

[Effects of the Invention] In summary, the present invention provides the following excellent effects.

(1) The sling is configured to run using wheels installed on the load center of the sling corresponding to the hook position and guide members arranged on both sides of the wheel to restrict swing of the sling, and the end of the running rail By separating one of the guide members from the rail when reaching this point, the wheel can be brought as close to the end of the rail as possible, and the range of movement of the hanging tool relative to the entire length of the hanging beam can be expanded.

(2) Therefore, the range of cargo handling operations can be expanded without extending the suspension beam.

(3) Since the guide member with a simple structure guides the movement of the hanging equipment, weight and cost reductions can be achieved.
