Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention receives a material to be constructed such as a construction material on a construction site, a waste disposal product in a garbage cleaning factory, a part in a general factory, a finished product, etc. The present invention relates to the hoisting and conveying device.

[0002]

2. Description of the Related Art Recently, a predetermined work space is provided above a building under construction, and a temporary frame which rises by itself along a main column or a temporary column is provided, and a plurality of transfer-type overhead traveling cranes are mounted on the temporary frame. , The hoist receives the material lifted up in one place, and the hoist is moved vertically and horizontally in a plane to convey it to a desired conveyance position in the plane of the temporary frame.

This transport device is, for example, as shown in FIG.
Three runway girders 1, 2, 3 fixedly arranged in parallel with each other on the temporary frame 01, and each runway girder 1,
Crane girders 4, 5 and 6 that are individually arranged so that they can travel orthogonally to 2, 3 and each runway girder 1,
Fixed girders 7, 8 and 9 arranged between 2 and 3 orthogonally to this, and a lifting machine 10 such as a cargo lift or a man-powered elevator arranged at one end of the runway girder 2 in the center.
And a pair of hoists 11 capable of moving in the lateral direction while transferring on the crane girders 4, 5, 6 and the fixed girders 7, 8, 9. Each hoist 11 is provided with the hoist 10.
The materials transferred from the above are transferred to the target transfer position while being transferred via each girder 4-9.

[0004]

In this structure, the number of hoists capable of carrying out the most efficient carrying work is two, but the work is completed even if the hoist 10 carries the material to the working floor. The work efficiency was poor because the empty hoist may be in a waiting state for delivery until it is carried to the lifting position by the central crane girder.

The above problems may occur not only in hoisting and carrying of construction materials at a construction site, but also in hoisting and carrying of waste materials such as waste disposal products in garbage cleaning factories, parts and finished products in general factories.

The present invention is intended to solve the above problems, and it is an object of the present invention to efficiently reduce the waiting time for a lift delivery in a hoisting and conveying apparatus equipped with the transfer hoist of the kind, and to efficiently achieve the object. The present invention provides a hoisting and conveying device that can convey to a conveying position.

[0007]

In order to achieve the above-mentioned object, the invention according to claim 1 is such that a plurality of runway girders and a plurality of runway girders arranged so as to run along the runway girders are orthogonal to the runway girders. Of the crane girder and a plurality of hoists capable of traveling on the crane girder, hoisting and carrying the object transferred to the hoist to the intended carrying position while transferring it via the crane girder. In the hoisting and conveying device configured as described above, at least two crane girders are arranged on at least one runway girder, so that the hoist is transferred from any crane girder to the adjacent crane girder, and again the original hoist is loaded. It can be transferred to the other crane girder located on the runway girder and moved to the target position. Can, also, one of the crane girder will be accepted standby state immediately empty load of the hoist after ERROR. Further, according to this configuration, since the replacement is possible, it is possible to add one hoist.

According to a second aspect of the invention, the two crane girders arranged in the one runway girder are:
Since each crane girder can move independently, each crane girder can stand by at the next movement position without performing unnecessary movement, and as a result, the overall transfer efficiency is significantly improved.

According to the third aspect of the present invention, by setting the retreat position of the crane girder at one end of one of the runway girders to which the transported object is transferred, the evacuation position of the crane girder is set. When the hoist is empty, there is no restriction on the replacement work, and the hoist can be moved to the target transfer position as short as possible.

In the invention according to claim 4, among the plurality of runway girders, the arrangement interval of any one of the runway girders to which the transported object is transferred is set narrower than the arrangement interval of the other runway girders. By shortening the length of the crane girder traveling on the runway girder, the weight of the runway girder can be reduced, and the speed in the runway direction can be increased.

According to a fifth aspect of the present invention, a plurality of fixed girders for transfer which are arranged between the respective runway girders and which can be linear with the respective crane girders are provided, and the transported object is the respective cranes. When the crane girder cannot be moved because it has a pillar in the middle by being hoisted and transferred to the intended transfer position while transferring via the girder and fixed girder, and as a result, the pillar interferes. Even if there is, it is possible to transfer the hoist between the crane girders by installing the fixed girder on the pillar, and even if the crane girders have different lengths, the hoist can be transferred via the fixed girder. It will be possible.

BEST MODE FOR CARRYING OUT THE INVENTION Embodiments of the present invention will be described in detail below with reference to the drawings.

FIG. 1 is a plan view showing the overall construction of an example in which the hoisting and carrying apparatus according to the present invention is applied to hoisting and carrying a construction material as an object to be carried. In the figure, a predetermined work space is placed above the building A indicated by the imaginary line under construction, and it rises along the main or temporary pillars, and it is similar to the projected area of the building and is made slightly larger. Temporary frame 2
0 is provided. The temporary frame 20 is a self-propelled type in which the inside of a substantially square frame is partitioned into a grid shape by steel or the like, and is jacked up as the construction progresses.

In the center of the temporary frame 20, runway girders 22 and runway girders 24 and 26 are also fixed in parallel on both sides of the temporary frame 20 in parallel in the longitudinal direction of the plane. The entire surface is covered by these.

On the central runway girder 22, two crane girders 28 and 30 are installed orthogonally to the runway girder 22, and each of them is independently movable in the vertical direction. Runway girders 24 and 26 on both sides
Each of the crane girders 32 and 34 is installed at a right angle so as to be vertically movable.

Further, between the runway girders 22 and the runway girders 24 and 26, there are predetermined three pairs of fixed girders 36, 38 and 40 for transfer which have the same height and width as the crane girders 28 to 34. It is fixedly arranged at intervals.

The runway girder 22 at the center is made longer than that on the left and right, and a hoist 42 such as a high-speed cargo lift or man-powered elevator is located at one lower end in the figure.

Further, one of the crane girders 28-
34 is used as a guide to reciprocate laterally 2
A platform hoist 44 is supported (in FIG. 1, supported by crane girders 30 and 32).

In the runway girder 22 in the center, the crane girder 28 near the hoist 42, that is, the lower side crane girder 28 in the figure (hereinafter referred to as the lower crane girder) serves both as a receiving and relaying suspended load and as an upper part. The side crane girder 30 (hereinafter referred to as the upper crane girder) also serves as a material transfer and relay.

In the above construction, as shown in FIG. 2A, the lower crane girder 28 is positioned directly above the hoist 42 with the hoist 44 supported, and the material is hoisted.
Received at 4 and this material is on the upper left of the figure [B]
2B, the lower crane girder 28 is moved to the nearest fixed girder 36 as shown in FIG. 2B.
(Hereinafter, referred to as a lower fixed girder) and stops, and at the same time, the left crane girder 32 also moves to and stops at the fixed girder 36, and after both are linearly positioned via the lower fixed girder 36, the suspension is performed. As shown by the arrow, the hoist 44 in the loaded state transfers to the left crane girder 32 side via the lower fixed girder 36 and stops. After that, the left crane girder 32 will move to the target position [a] as shown by the arrow.
Move vertically up to.

Further, in parallel with this, when the hoist 44 supported by the right crane girder 34 is empty and is going to receive the material, the hoist 44 is moved to the stop position as shown in FIG. 2 (b). When approaching a lower crane girder 28 and stopping collinearly through the lower fixed girder 36, the hoist 44 transfers onto the lower crane girder 28. After the transfer, the right crane girder 34 is stopped at this position and is in a standby state, while the lower crane girder 28 is shown in FIG.
As shown in (c), the hoist 44 is located directly above the hoist 42 and receives the material from the hoist 42.

After receiving this load, the lower crane girder 28 is again used.
Stops moving to the lower fixed girder 36, then the hoist 44 transfers to the right crane girder 34, and then the right crane girder 34 moves toward the target position.

When the target conveying position of the material is the position [b] which is the upper center of the figure, the upper crane girder 30 stopped at an arbitrary central position is also on the right side as shown in FIG. 2 (d). They move in the same direction as the crane girder 34 and stop at a fixed girder 40 (hereinafter referred to as an upper fixed girder) on the upper side of the drawing which is the meeting point of both, and then the hoist 44 moves to the central upper crane girder 30. After the transfer and stop, the upper crane girder 30 moves to the target position [b], while the left crane girder 32 that has unloaded the target position [a] moves to the lower crane girder 28 waiting at the stop position. , The empty hoist 44 moves and transfers to the center side when they meet via the lower fixed girder 36.

The right and upper crane girders 3
The destination of the suspended load passing through 4 and 30 is the same destination [a]
In the case of, the upper crane girder 30 remains stopped at the position of the upper fixed girder 40, while the right crane girder 34 stops moving again to the upper fixed girder 40, and then the hoist 40 on the upper crane girder 30 moves to the left side. It is transferred to the crane girder 32 and then transported to the target position [a]. However, if the destination of the suspended load is within the movement range of the right crane girder 34, the upper crane girder 3
0 is kept dormant from the beginning.

The fixed girder 38 in the center is also appropriately used so that the moving distance from the hoist 42 is the shortest distance in accordance with the target conveying position. The lower crane girder 28 can be moved to the position of the central fixed girder 38 depending on the working conditions.

Since the hoist 44 can be transferred to one of the crane girders 28 and 30 by the above replacement work,
One hoist 44 can be added from the state shown. However, in this case, the replacement work accompanying the transfer becomes complicated, and the work efficiency may be lowered on the contrary. Therefore, when adding the hoist 44, one end side of the runway girder 22 at the center is lifted as shown in FIG. If the extension is performed by intersecting the heavy equipment 42 and the extension end 22a is set to the retracted position of the lower crane girder 28, the replacement work becomes easy.

For example, when transporting a suspended load toward the target position [B], one crane girder 28 with the hoist 44 in an empty state is placed in the retracted position and the other crane girder 30 is lifted. The hoist 44 placed directly above 42 receives the suspended load, the crane girder 30 is directly advanced to the target position [b], and then one crane girder 28 is positioned directly above the hoist 42. It is sufficient to receive the suspended load.

It should be noted that the moving direction and stop position of each crane girder 28-34, the position of each hoist 44 and the presence or absence of a suspended load,
Since the lift of the hoist 42 can be detected by a sensor or the like, once the target transfer position is determined, the crane girders 28 to 28-
Movement control of 34 and each hoist 44 can be performed.

In addition to the above construction, the crane girder 28 (30) is transferred to the lifting machine by providing a runway girder-like beam which can be transferred to the crane girder 28 (30) on which the hoist 44 is mounted on the lifting machine 42. It is also possible to employ a configuration in which the hoist is supported by descending to near the ground and transferring the material delivered there through the crane girders 28 (30) while hoisting and carrying it to the intended carrying position. Materials can be delivered near the above-ground part together with the crane girder, increasing flexibility during transportation, and at the same time, the remaining crane girder can be utilized for material transportation.

Also, by setting the installation interval of the central runway girder 22 to be narrow, the length of the crane girder 28 (30) that moves along this can be shortened, and its weight reduction makes it possible to speed up the runway direction. Becomes

In the construction site, the fixed girders 36, 38, 40 in each of the above-described embodiments are mainly constructed so that the erection work 20 does not have a large span but has a pillar in the middle, and as a result, the pillar row is Each crane girder 28-3
It is arranged when both ends of 4 cannot be matched, and is not necessarily required when there is no obstacle due to a column row, etc.
It is possible to make the hoists 44 transferable by matching the 34 with each other.

Further, in the above-mentioned embodiment, the construction material is exemplified as the transported object, but the present invention is not limited to the above-described embodiment, and as the transported object, for example, a waste disposed of in a garbage cleaning factory, a general It can also be applied to lifting and transporting parts, finished products and other things in factories. Then, for example, when the present invention is applied to a garbage cleaning plant, it is needless to say that the fixed girder is arranged at a position avoiding the pillars erected at appropriate places in the vast garbage collection hole (in other words, Pillars are placed between the fixed girders).

[0033]

As described above in detail with reference to the embodiments, in the invention according to claim 1, at least two crane girders are arranged on at least one runway girder so that any one of the hoists can be provided. It is possible to transfer it from the crane girder to the adjacent crane girder, transfer it to the other crane girder located on the original runway girder again and move it to the target position, and one crane girder immediately after transfer Since the standby state for receiving the empty hoist is achieved, it is possible to shorten the delivery waiting time of the transported object and efficiently transport the transported object to the target position. Further, according to this configuration, since the replacement is possible, it is possible to add one hoist.

In the invention according to claim 2, the two crane girders arranged in the one runway girder are:
Since each crane girder can move independently, each crane girder can stand by at the next movement position without performing unnecessary movement, and as a result, the overall transfer efficiency is significantly improved.

According to the third aspect of the present invention, by setting the retreat position of the crane girder at one end of any one of the runway girders to which the transported object is transferred, the evacuation position of the crane girder is set. When the hoist is empty, there is no restriction on the replacement work, the hoist can be moved to the target transfer position in the shortest direction, and the work efficiency can be further improved.

According to a fourth aspect of the present invention, among the plurality of runway girders, the arrangement interval of any one runway girder to which the transported object is transferred is set to be narrower than the arrangement interval of the other runway girders. By shortening the length of the crane girder traveling on the runway girder, the weight of the runway girder can be reduced, and the speed in the runway direction can be increased.

According to a fifth aspect of the present invention, a plurality of fixed girders for transfer which are arranged between the respective runway girders and which can be linear with the respective crane girders are provided, and the transported object is the respective cranes. When the crane girder cannot be moved because it has a pillar in the middle by being hoisted and transferred to the intended transfer position while transferring via the girder and fixed girder, and as a result, the pillar interferes. Even if there is, it is possible to transfer the hoist between the crane girders by installing the fixed girder on the pillar, and even if the crane girders have different lengths, the hoist can be transferred via the fixed girder. It will be possible.
