Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a suspended load transfer device mounted on a single overhead crane rail, and for replacing damaged rails and raising and lowering working equipment tools when the overhead crane is damaged. The present invention relates to a suspended load transfer device used.

[0002]

2. Description of the Related Art The contents of an overhead crane are shown in, for example, "Handbook of Mechanical Engineering, 5th edition, 5th edition, revised on August 10, 1974, published by The Japan Society of Mechanical Engineers, pages 16-4 to 16-7". It travels on the overhead crane rails fixed by fixed hardware on the overhead crane traveling girders with a height of several meters to several tens of meters, and can be used for moving goods in the factory or lifting equipment when repairing equipment. Is what is used. Each of the above-mentioned overhead crane rails usually has a length of about 10 m, and its weight varies from several hundred kg to 1 ton although it varies depending on the type.
There is on. When an overhead crane traveling rail is damaged and the rail is replaced with a new rail, in order to lower the damaged rail to the ground and lift the new rail, for example, see [Mechanical Engineering Handbook, 16-12, 16-13] above. As shown, a hoist such as a truck crane in which a swing hoist is mounted on the truck is used.

[0003]

However, it is necessary to secure a working place for the truck crane, and further, in order to enter the truck crane under the damaged rail,
You have to move equipment and products in the factory in advance,
When performing the overhead crane rail replacement work, there was a problem in that the moving work that was the preparatory work was very troublesome. Further, in a factory equipped with an overhead crane, there are fixed facilities such as a product manufacturing facility and an operation room, so that the truck crane may not be able to enter below a damaged rail. In this case, after moving the truck crane to a position where it can be approached in the factory, the replacement rail was unloaded onto the overhead crane traveling girder, and the crane corridor was moved to the replacement work position by the trolley and manpower. Then, after removing the damaged rail from the track, the rail is moved above the waiting position of the truck crane on the crane corridor using a truck or a chain block, and then suspended on the ground by the truck crane. It was In particular, the removal of the damaged rail from the track, the loading on the truck, and the unloading and mounting of the replacement rail from the truck were manual work using a chain block. Lubricants on the wheels of the overhead crane spilled and adhered to the feet of workers performing rail movement / removal / installation work.
It is very slippery. For this reason, there is a problem that a worker who is replacing the overhead crane rail is always caught in a risk of being caught by falling or swinging the rail and falling or falling to cause injury. During the overhead crane rail replacement work, the factory is forced to stop, but in the conventional overhead crane rail replacement work, as described above, the approach path and work place of the truck crane are secured, the chain block is used for lifting and lowering, Since the overhead crane rails are moved on the crane corridor manually, many days are required and the economic loss is enormous. Therefore, in the work of exchanging overhead crane rails, the advent of a device that enables the rails to be lifted and moved safely in a short time without securing an approach path for a truck crane has been desired. The present invention has been made in view of the above circumstances, and an object of the present invention is to provide a suspended load transfer device that does not require an access path for hoisting machines such as truck cranes and a work place, or movement on the crane corridor.

A suspended load moving device 10 according to an embodiment of the present invention.
Is mounted on a traveling carriage 12 traveling on the upper surface of an overhead crane rail 11 as shown in FIG.
3) A swing having a gate-shaped hoist mount 15 loosely fitted in the recess 14 formed in the center of the 3 and a device for hoisting and unwinding a rail such as a damaged rail or a new rail via a rope or a chain. The hoist frame 16 and the hoist frame 15 are connected by a hydraulic cylinder 17, and the swivel hoist 16 is connected to an upper part of the hoist frame 15 via a rotating mechanism 18a.

As shown in FIGS. 1 to 4, the traveling carriage 12 is connected to a pair of front and rear traveling wheels 18, a guide roller 20 sandwiching a rail head portion 19 of an overhead crane rail 11, and one side of the traveling wheel 18. In addition, it is configured by a traveling wheel drive device (not shown) including a hydraulic motor and valves. FIG. 3 shows a cross section CC in FIG. 1.
The front and rear of the hoist frame 15 are gate-shaped, and legs (an example of leg members) 21 are provided on both front and rear sides, and inner portions 22 of the legs 21 on both sides are fitted to outer surfaces of both inner frames 23 of the traveling carriage 12. Accordingly, when the hoist mount 15 can be moved up and down by the hydraulic cylinder 17, and the hoist mount 15 is lowered,
The front and rear legs 21 on both sides come into contact with the upper surface of the traveling girder 24 which is the installation surface of the overhead crane rail 11.

A pair of holding arms 25 having hook-shaped lower ends opposed to each other are provided near the upper and lower sides of the hoist frame 15.
The pair of holding arms 25 are hung so as to be drivable via 6 and are connected by a hydraulic cylinder 28 via pins 27 and 27a. 3 shows a state in which the hoist frame 15 is fixed to the overhead crane rails 11 by compressing the hydraulic cylinders 28 to pinch the webs 29 of the overhead crane rails 11 at the tips of the respective holding arms 25.

Since the overhead crane rail 11 is strong and is firmly fixed to the traveling girder 24 by the rail clamp 30, the boom 31 of the swing hoist 16 connected to the upper part of the hoist frame 15 is fixed. Even if a damaged rail or a new rail is hung on the tip of the rail, it will not fall even if it turns. Further, since the front and rear ends of the hoist 15 are fitted in the recess 14 of the traveling carriage 12 with a slight gap as shown in FIG. 1, the tip of the boom 31 of the swing hoist 16 is damaged. The rails or new rails are hung so that the displacement of the boom 31 does not occur even if the boom 31 is turned.

Further, in the suspended load moving device 10, when a damaged rail or a new rail is hung, a force of falling is applied. The force is, as shown in FIG. 8, the hoist mount located on the damaged rail 32 side. The lower end 33 of the leg 21 of 15 serves as a fulcrum, and the tip of the holding arm 25 is supported by a holding force formed by pressing the web 29 of the overhead crane rail 11. Therefore, the suspended load transfer device 10 can hang the damaged rail 32 from the position of the overhead crane rail 11 or can lift the new rail 20 from the floor surface and place it next to the overhead crane rail 11.

It should be noted that FIG.
An example of a situation where the damaged rail 32 is being unloaded using a table is shown. Wire ropes 34 and 35 are hung on both ends of the damaged rail 32, respectively, and the two suspended load transfer devices 1
It is a figure in which the wire ropes 34 and 35 are hung on the hooks 36 of the respective hoists 16 of 0, and the hoisting is simultaneously carried out. Incidentally, 37 is a winch.

FIG. 4 is a sectional view taken along the line A--A in FIG. 1, in which bearings 38, 39 are provided on both upper sides of the front and rear portions of the bogie frame 13 of the traveling bogie 12, and the respective bearings 38, 39 are provided. A pair of hook-shaped guide roller arms 40 each having the above-mentioned guide roller 20 at its lower end,
41 are hung facing each other, and the intermediate portions of the pair of guide roller arms 40, 41 are connected by a hydraulic cylinder 43 via pins 42, 42a. Due to this structure, the head 1 of the overhead crane rail 11
The guide roller arms 40 and 41 located below
By expanding and contracting the hydraulic cylinder 43, the guide roller 20 can be taken in and out from below the rail head 19. The guide roller arm 40 when the hydraulic cylinder 43 is contracted,
The reference numeral 41 designates a position where the guide roller 20 abuts below the rail head portion 19 of the overhead crane rail 11 and holds a gap required for rolling, and the guide roller arms 40, 4 are provided.
It is attached to the tip of 1.

Therefore, when the suspended load moving device 10 is desired to travel, the hydraulic cylinder 43 is contracted as shown in FIG. 4, and the guide rollers 20 attached to the lower ends of the guide roller arms 40 and 41 are moved to the rail head. After abutting against the lower surface of 19, the hydraulic cylinder 28 is extended as shown in FIG. 7 to widen the gap between the tips of the opposing clamping arms 25 to be wider than the width of the rail head 19 of the overhead crane rail 11, As shown in FIG. 4, the hydraulic cylinder 17 provided in the traveling carriage 12 is extended, and the hoist frame 15 is lifted until the lower ends 33 of the legs 21 on the front, rear, left and right of the hoist frame 15 reach or exceed the top end height of the rail clamp 30. The device 10 moves the rail head 19 over the overhead crane rail 11.
While the lower surface of the vehicle is supported by the guide roller 20, the traveling wheel 1
With 8, it is possible to drive without falling.

Then, by using two of the suspended load moving devices 10 side by side, an overhead crane rail moving device is constructed as shown in FIG. 12, and a new rail 44 is provided directly above and close to the overhead crane rail 11. By positioning and hanging the new rail 44,
It is possible to travel on the overhead crane rail 11. Here, the suspended new rail 44 has a low center of gravity and is located directly above the overhead crane rail 11, and therefore has little influence on the overturning of the suspended load transfer device 10. Therefore, the suspended load moving device 10 can travel while being sufficiently supported by the guide roller 20 below the rail head 19 even though the new rail 44 is suspended.

[0016] The new rail 4 that is suspended during traveling
In order to prevent 4 from rolling laterally, a reverse groove type guide 45 as shown in FIG. 11 is put on the new rail 44 that is being suspended, and both skirts of the guide 45 are rail heads of the overhead crane rail 11. By making it hang on the side surface of 19, it is possible to drive more safely. In addition, as shown in FIGS. 6 and 7, the suspended load moving device 10 is in a state in which the pair of guide rollers 20 and the pair of clamping arms 25 are spread wider than the width of the rail head 19 of the overhead crane rail 11. It is possible to lift and remove it from any place under the overhead crane rail 11 by using a truck crane (not shown). Further, in this state, the entire device is lowered and the traveling wheels 18 are mounted on the overhead crane rail 11. By placing it and closing the pair of guide rollers 20, the suspended load moving device 10 can be assembled to the overhead crane rail 11 in a travelable state.

The suspended load moving device 10 can move the rails by arranging the gate-shaped columns at appropriate intervals, laying rails on the gate-shaped columns, and moving the rails. The required levelness of the top surface of the rail can be easily obtained by laying an interposition between the rail and the gate column. Moreover,
Adjacent 2 like conventional overhead crane rails and train tracks
Since it is not necessary to make the rails of the row the same level in the vertical direction, the rail laying work for the suspended load transfer device 10 of the present invention is simple. Therefore, it is possible to easily lay the rail even in a complicated terrain or mountainous area with a lot of unevenness. Therefore, the suspended load transfer device 10 has an advantage that it can be easily used for hoisting, hoisting, and carrying of materials in complicated terrain or mountainous areas with severe unevenness.

In this embodiment, the leg members are formed on both sides of the hoist mount, but they can be attached to the carriage independently. Further, if the working direction of the hoist is set to one direction, the leg members can be attached. Can be provided on only one side, and the present invention is applied to this case as well.

[0019]

As is apparent from the above description, the suspended load moving device according to the first and second aspects can transport a damaged rail or a new rail by using one overhead crane rail. As a result, it has become possible to hang up the damaged rails and mount new rails at any place where a truck crane under the overhead crane rail can approach. With the conventional method, it is not necessary to remove and restore the obstacle equipment that was necessary to secure the access path for the truck crane until the location near the damaged rail location, and the time required for this operation can be used for factory operation. The economic benefits of allocating it are huge.
Also, with the conventional method, it was necessary to move the damaged rail and the new rail along the overhead crane rail, but since this work was eliminated, there is no concern that the worker will be injured due to a fall or being caught. It was
