Description

The present invention relates to a vertical transportation (lifting) and a horizontal transportation of materials in a building such as a building, and an assembling of a steel frame material.
Or sliding type swivel that can perform crane work by free combination of horizontal swiveling motion and linear sliding motion, widely used for applications such as overhead cranes that move (distribute) various goods in warehouses and factories. About cranes.

2. Description of the Related Art Conventionally, tower cranes, jib cranes, mobile cranes, and the like are often used for construction purposes. In factories and warehouses, overhead cranes are often used for distribution. The former carries out crane work only by turning movement or turning and raising, and the latter carries out crane work by horizontal vertical and horizontal linear movement.

In short, there has been no conventional crane operation that can be freely combined with a horizontal turning motion and a linear sliding motion to perform a wide range of crane operations.

Problems to be Solved by the Present Invention I) A tower crane, a jib crane, or the like has a configuration in which only a swiveling motion or a crane operation by a swiveling motion and an elevating operation can be performed, and only a crane operation within a swiveling range (a range where a boom can reach) is possible. No, the working range is relatively small. Therefore, in order to perform a wide range of crane operations, a large number of cranes must be installed in an arrangement in which the swivel ranges partially overlap. Further, even within the turning range, the crane operation near the turning center is relatively inconvenient in relation to the elevation of the boom. Furthermore, even within the turning range, in order to demonstrate the freedom and efficiency of crane work, the jib or boom must have a degree of freedom of elevation, so a three-dimensional work that is sufficiently wide in the horizontal and vertical directions Space is required and application conditions are restricted. For example, when constructing the underground structure of a building, in order to transport and assemble materials with a shib crane etc. installed on the ground, if the boom or jib can freely rotate and elevate, it will be necessary to assemble the upper structure on the ground It causes trouble. Conversely, crane work is often restricted.

Or, when constructing a high-rise building, installing a swivel crane not only at the top of the building but also near the middle part, and further installing swivel cranes on each floor of the building and proceeding with construction work is a conventional crane configuration. It was impossible at all.

II) Conventionally, overhead cranes used for logistics in factories and warehouses can perform crane work by two-dimensional vertical and horizontal movement on the horizontal plane, but they do not have a swivel function. There is a disadvantage of low degree of freedom.

 The above is the problem to be solved by the present invention.

Means for Solving the Problems As means for solving the above-mentioned problems of the prior art, a sliding type swiveling crane according to the present invention mainly includes an embodiment as shown in FIGS. 1 to 9 of the drawings. A) a circular rail 1 mounted and fixed substantially horizontally on the lower surface of the horizontal member 100 or the like; b) disposed on the lower surface side of the circular rail 1 in the direction of the diameter of the circular rail 1 and turned on the circular rail 1 A linear swivel rail 2 slidably suspended by a self-propelled support device such as a traveling electric trolley 4, c) a lower surface side of the swivel rail 2, which is arranged substantially parallel to the swivel rail 2; A linear slide rail 3 movably suspended by a self-propelled support device such as an electric trolley 5 traveling on the swivel rail 2; d) the slide rail 3 is slidably mounted over the entire length of the slide rail 3; Self-propelled such as hoist 6 And lifting machine, characterized in that it further consists. However, this is a slide type swiveling crane of a single slide type.

On the other hand, the configuration of the slide type swiveling crane of both slide types is mainly as shown in the embodiment in FIGS. 10 to 18 of the drawings, a) a circular shape which is fixed substantially horizontally to the lower surface of the horizontal member 100 or the like. B) A self-propelled support device such as an electric trolley 4 that is disposed on the lower surface side of the circular rail 1 in the diameter direction of the circular rail 1 and that runs on the circular rail. C) a self-propelled support device, such as an electric trolley 5, which is disposed on the lower surface side of the turning rail 2 and is substantially parallel to the turning rail 2 and runs on the turning rail 2. A suspended suspension beam 10, and an inverted electric trolley 12 attached to the suspension beam 10.
A) a linear slide rail 3 movably supported by a self-propelled support device such as: e) a self-propelled lifting device such as a hoist 6 movably installed on the slide rail 3 over its entire length; Characterized by comprising:

First, the slide type swiveling crane of the present invention is provided with a center plate 1b at the center of the circular surface of the circular rail 1, and the center plate 1b is provided with a vertical shaft hole at the center position of the circular rail 1. 7 is provided, and a turning shaft 8 is projected upward at the turning center position of the turning rail 2 on the lower surface side, and the turning shaft 8 is rotatably supported by the shaft hole 7 of the center plate 1b (No. Second, the turning rail 2 and the slide rail 3 are two rails 2, 2 arranged in parallel at a predetermined interval, respectively.
Or, three and three are rigidly connected by the connecting members 2a or 3a, respectively, and two self-propelled hoists such as two hoists 6,6 are respectively provided on two slide rails 3,3. Third, ceiling beams 110 of warehouses and the like (FIG. 28), or girder members 111 of a lifting work stage for building construction (FIG. 25), Alternatively, a girder of the upper layer of the building assembled in advance is a horizontal member for suspending the circular rail 1.

Further, in the sliding type swiveling crane of the present invention, the horizontal connecting members 3a and 3b are supported by a self-propelled supporting device such as an electric trolley 5 running on the turning rail 1 (FIGS. 21 and 23). Slide rail 3 supported by 3a, 3b
Is supported at a height substantially equal to that of the swing rail 2, and a self-propelled lifting machine such as a hoist 6 is installed on the slide rail 3 (FIGS. 19 to 24).
Figure). This crane is of a reduced type in which the slide rail 3 is supported higher so as to be closer to the horizontal member 100.

Operation The horizontal member 100 is an object to be mounted on the sliding type swiveling crane. If the horizontal member 100 is, for example, a girder member 111 (FIG. 25) of a work stage which moves up and down in the vertical direction, the sliding type swiveling crane is of a lifting type. When a girder at the top or middle layer of the building assembled beforehand is used as the horizontal member 100, the sliding type swiveling crane can be used for building construction. When the girder on the first floor of the building is used as the horizontal member 100, it can be used for constructing the underground structure of the building. When a beam on the ceiling of a factory or a warehouse is used as the horizontal member 110 (FIG. 28), the sliding type swiveling crane can be used for distribution in a factory or a warehouse.

When the electric trolley 4 turns on the circular rail 1,
The turning rail 2 suspended from the electric trolley 4 is turned by the turning angle corresponding to the traveling circumferential length. Therefore, the diameter of the circular rail 1 or the length of the turning rail 2 is the turning range d (FIG. 1). Since the electric trolley 4 can turn on the circular rail 1 endlessly, the turning rail 2
Can be turned over 360 旋回 if necessary.

When the electric trolley 5 travels on the linear turning rail 2, the slide rail 3 suspended from the electric trolley 5 slides along the turning rail 2 as shown in FIG. 2 or FIG. It moves (extends) linearly. Therefore, the tip end of the slide rail 3 protrudes out of the swivel range of the swivel rail 2 by a length corresponding to the effective stroke, thereby enabling an expanded crane working range D (see FIG. 1).

The hoist 6 moves over the entire length of the slide rail 3 to move the hook 9. Therefore, the length of the slide rail 3 is the hook movement range W (FIG. 2), and the hoist 6 lifts (lifts) materials from below at any position within the range of the effective length of the slide rail 3. ), It can be transported horizontally within the limit of the length of the slide rail 3. Therefore, if the slide rail 3 protrudes from the turning range d, it performs lifting and horizontal transport from inside the turning range to the outside, or lifting and horizontal transport of materials from outside the turning range to the inside. Can be.

The swivel rail 2 performs a swivel motion constrained about a swivel shaft 8 supported by a shaft hole 7 of the circular rail 1. A so-called slip ring is provided in the shaft hole 7 and the turning shaft 8 to constitute a power supply device for supplying electricity to each electric facility of the turning crane from a power source.

When a total of two (or more than two) hoists 6,6, one for each slide rail 3,3, are used, the materials to be transported, for example, the steel beam 101, are used as the steel column material. 1
It can be suspended at two points such as 03, or at multiple points, and by taking into account the position of the center of gravity, attitude control in the air becomes possible (see FIGS. 19 and 20).

A sliding type swiveling crane in which the swivel rail 2 and the slide rail 3 are arranged at substantially the same height (FIGS. 19 to 24)
In the figure, since the height of the hoist 6 and the hook 9 installed on the slide rail 3 becomes substantially high, and the materials hung on the hook 9 can be hung high, the lifting and lifting within the limited building floor height can be achieved. The degree of freedom of crane work such as horizontal transportation can be increased.

Embodiment Next, the illustrated embodiment of the present invention will be described.

First, FIG. 1 to FIG. 3 show the configuration principle diagram and operation of a single-slide type sliding type swiveling crane which is a first embodiment of the present invention, and FIG. 4 to FIG. An example is shown.

On the lower surface of the horizontal transverse member 100, a rail 1 having a circular shape with a plane shape of about 9.5 m in diameter is attached and fixed substantially horizontally.
As shown in FIG. 8, the upper flange of the circular rail 1 is brought into contact with the lower surface of the flange of the horizontal member 100, which is a steel frame material.
It is fastened and fixed. For the circular rail 1, an I-shaped member having a size of about 300 × 150 mm is used. The diameter (approximately 9.5 m) of the circular rail 1 is a turning range d (see FIG. 1) of the slide type turning crane.

A linear turning rail 2 (see FIG. 1) disposed on the lower surface side of the circular rail 1 in the diameter direction of the circular rail 1.
Is rotatably suspended by an electric trolley 4 which turns on a circular rail 1 (however, any self-propelled supporting machine having a self-propelling function and a suspension supporting function is also possible, the same applies hereinafter). I have. For example, as shown in FIG. 24, each of the swing rails 2 uses two section steels each having a size of about 250 × 150 mm and a length of about 9.9 m, which is slightly larger than the diameter of the circular rail 1. They are arranged in parallel at an interval of about 1.5 m and are integrally rigidly connected with several horizontal connecting members 2a. A total of four electric trolleys 4 are used, one at each end of the two swing rails 2, 2 (FIG. 4).

Details of the structure for suspending the swivel rail 2 by the electric trolley 4 are shown in FIGS. 7 and 8, and a drive wheel 4a on one side and a follower wheel 4c on the other side ride on the lower flange of the circular rail 1.
A common trolley yoke is located on both sides of the rail web
Installed in 4d. The swing rail 2 is suspended and supported below the trolley yoke 4d via a suspension bracket 31. The rated lifting load of the electric trolley 4 is set to about 5 tons. The drive wheel 4a is driven to rotate by a brake-equipped motor 4b. The electric trolley 4 is controlled to advance, reverse, and stop by wired (or wireless) remote control using a push-button type operation box, and turns at a rated speed of about 6 to 24 m / min. Therefore, by making the electric trolley 4 run at the rated speed, the swing rail 2 can be turned 360 ° in about one minute. Then, if necessary, it is possible to turn the endlessly necessary number of times and to the required turning angle.

24, the two beams 1a, 1a are approximately 1.5 m in the direction of the diameter in the circular plane of the circular rail 1.
The ends are rigidly connected to the circular rail 1 at both ends in a parallel arrangement. A center plate 1b supported by the two beams 1a, 1a is installed at the center of the circular rail 1. The center plate 1b is provided with an axial hole in the center of the circular rail 1 in the vertical direction (vertical direction). 7 are provided. On the other hand, on the horizontal connecting member 2a at the center of the turning rail 2, a turning shaft 8 is vertically projected upward at the center (turning center) of the two turning rails 2. It is rotatably supported in the shaft hole 7. Therefore, the turning rail 2 is turned by the synchronous control of the motors 4b of the four electric trolleys 4 and also makes a turning motion about the turning shaft 8 restricted by the shaft hole 7 exactly. A slip ring 39 (FIG. 7) is provided between the shaft hole 7 and the turning shaft 8, and constitutes a power supply device for supplying electricity from a power source to the electric equipment of the turning crane.

On the lower surface side of the swing rail 2, a linear slide rail 3 is also movably suspended by an electric trolley 5 running on the swing rail 2. This slide rail 3 also has a size of 35 mm for easy understanding in FIG.
Use two rails 3,3 using I-shaped steel of about 0x150mm and length of about 9.9m, and connect these two rails 3,3
Arrange in parallel with 1.5m intervals same as 2, 2 and several horizontal connecting materials 3
a (see FIG. 4), they are integrally rigidly connected, and are arranged in parallel with a position directly below the swing rail 2. Therefore, when the slide rail 3 is completely contracted,
As shown in FIG. 3 or FIG. 6, the arrangement is substantially vertically symmetric with respect to the swivel rail 2 and substantially falls within the swivel range d.

The electric trolley 5 for suspending the slide rail 3 is the fifth,
As is clear from FIG. 6, two units are used, one at the rear end (the end on the non-projecting side) of the slide rail 3 and one at a position slightly forward of the turning center. The details of the suspension structure are shown in FIGS. 7 and 8, the decoy, and a driving wheel 5a and a driving wheel 5a that run on the upper surface of the lower flange are provided on the left turning rail 2 in FIG. An electric trolley 5 is installed in which trolley yokes 5c are symmetrically arranged on both sides of a rail web and motors with brakes 5b for rotationally driving the trolley yoke 5c are installed. In FIG. 7, the right swing rail 2 is provided with a driven trolley in which free wheels 5e running on the upper surface of a lower flange thereof are symmetrically arranged on a trolley yoke 5f on both sides of the rail web. . The slide rails 3, 3 directly below the trolley yokes 5c, 5f are suspended and supported by suspension metal fittings 32, respectively. No.
In FIGS. 5 and 6, the electric trolley 5 located forward (leftward) from the center of rotation is configured such that the drive side and the driven side thereof are arranged exactly opposite to those in FIG. The rated lifting load of this electric trolley 5 is 5 tons, and the rated speed is 6 to
It is around 24m / min.

Therefore, each motor 5 of the two electric trolleys 5
Wired (or wireless) with a push-button type operation box
By controlling the forward, reverse, and stop by remote control of, the slide rail 3 is quickly pushed out or contracted and the positioning stop operation is performed at the position of the turning angle where the turning rail 2 is stopped. Incidentally, in each of the above-described dimensional specifications, the front end of the slide rail 3 can protrude up to about 4 m from one end of the turning rail 2 forming the turning range d (FIG. 5). Therefore, as shown in FIG. 1, the crane operation can be performed up to a range of D = d + 8, which is expanded by 4 m outside the turning range d. In this embodiment, D is about 18 m.

In FIG. 8, reference numeral 34 denotes an anti-lifting wheel installed at the rear end of the slide rail 3 for transmitting a bending moment generated when the slide rail 3 protrudes to the upper swing rail 2 to take a reaction force.

The two slide rails 3, 3 are provided with a hoist 6 (or a self-propelled lifting machine having a self-propelling function, a lifting function and a lifting capacity, which can travel over its effective length (about 9.9 m). If so, the same applies to the following), one rail 3 (or two or more if necessary) is installed in total. The hoist 6 is roughly divided into an electric trolley 60 and an electric chain block 61 as shown in detail in FIG.
And both are integrally assembled via a frame 62. As shown in FIG. 7, the electric trolley 60 includes a drive wheel 6a on the upper surface of the lower flange of the slide rail 3 and a motor 6b with a brake for rotating the drive wheel 6a.
The trolley yoke with symmetrical arrangement on both sides of the rail web
6c, and at the bottom of the trolley yoke 6c,
The guide sheave 64 of the chain 63 extended from the frame 62 and the electric chain block 61 is attached. The rated traveling speed of the electric trolley 60 is about 6 to 24 m / min.

The electric chain block 61 is of an electric type driven by a motor 65, and has a chain bucket 66 attached thereto. The electric chain block 61 includes a free wheel 6e that rides on the upper surface of the lower flange of the slide rail 3 as shown in FIG.
Yoke with 6e symmetrically placed on both sides of rail web
It is suspended on a driven trolley 67 composed of 6f or the like. By the way, the rated lifting load of this electric chain block 61 is 1.5
Ton, head is 15m, hoisting speed is about 2.6m ~ 7.9m / min.

Therefore, the hoist 6 traverses the entire length of the slide rail 3 by controlling the forward / backward and stop of the motor 6b of the electric trolley 60 by wired (or wireless) remote control using a push button type operation box. , Which is the hook movement range W (FIGS. 2 and 3). Further, by lifting, lowering and stopping the motor 65 of the electric chain block 61, the materials suspended on the hook 9 can be lifted.

In this sliding type swiveling crane, the height from the lower surface of the horizontal member 100 to the lower surface of the lower flange of the slide rail 3 is about 1.2 m.

Second Embodiment FIGS. 10 to 13 show a double slide type (that is, a method in which a slide rail 3 protrudes not only in one end direction of a turning rail 2 but also in the other end direction) according to a second embodiment of the present invention. 14) shows the principle of construction and operation of the sliding type swiveling crane, and FIGS. 14 to 17 show a specific embodiment thereof.

The slide-type swiveling crane of the present embodiment is also configured by a combination of the circular rail 1, the swivel rail 2, and the slide rail 3, just like the single-slide type slide-type swivel crane of the first embodiment. It is characterized by a structure in which the slide rail 3 is suspended by the electric trolley 5.

As shown in FIG. 18, the details are shown in FIG. 18, and the lower part of the trolley yoke 5c of the electric trolley 5 is constructed so that the driving wheel 5a running on the upper surface of the lower flange of the turning rail 2 is driven to rotate by the motor 5b with the brake. A suspension beam 10 made of square steel pipes arranged in parallel directly below the rail 2
It is suspended and supported. Conversely, the drive wheel 12a supporting the lower surface of the upper flange of the slide rail 3 is
An inverted electric trolley 12, which is driven to rotate by 2b, is arranged close to the front and back of the electric trolley 5 in the rail axis direction (FIGS. 15 to 17). The upper part is also hung and supported by the hanging beam 10 with a kansashi pin 13, and the slide rail 3 is hung so as to be movable in both directions. This is because the slide rail 3 can be moved in the left-right direction in the figure by operating the drive wheels 12a of the inverted electric trolley 12 forward or backward. Then, from the state where the slide rail 3 is within the turning range as shown in FIG. 16, the electric trolleys 5, 5 are driven to the left to move the electric trolley 5 on the left side of the drawing as shown in FIG. After the vehicle has been driven to the left-hand limit, the inverted trolley 12 is similarly driven leftward to move the slide rail 3 to the right-hand trolley 12 in the figure.
, The left end of the slide rail 3 protrudes leftward by about 3.9 m. Conversely, after the electric trolleys 5, 5 are driven to the right and the right electric trolley 5 in the figure is driven to the right-hand limit of the turning rail 2 as shown in FIG. 17, the inverted electric trolleys 12, 12 are further moved to the right. When the slide rail 3 is driven to the right-hand drive limit with respect to the electric trolley 12 on the left side in the figure, the slide rail 3
The right end of the is projected about 3.9m to the right.

Accordingly, the range of movement of the hook 9 of the hoist 6 is essentially the range W of the effective length of the slide rail 3 (17th.
According to these two slide types, the substantial hook movement range is expanded to the distance from the position of the hook 9 in FIG. 15 to the position of the hook 9 in FIG. This corresponds to about twice the slide format. Therefore, as long as the linear horizontal movement is performed, the position change in FIGS. 15 and 17 is the same as that in the case where the swing rail 2 is rotated by 180 ° in the single slide type swing crane of the first embodiment. Conversely, in the case of the double slide type of the present embodiment, the frequency of turning of the turning rail 2 can be reduced, and a crane operation in a wider range can be performed freely.

Third Embodiment FIGS. 19 to 24 show a sliding-type swiveling crane according to a third embodiment of the present invention.

The sliding-type swiveling crane of this embodiment is also composed of a combination of a circular rail 1, a swivel rail 2 and a slide rail 3, just like the sliding-type swiveling cranes of the first and second embodiments. However, it is characterized in that the swing rail 2 and the slide rail 3 are configured to have substantially the same height, so that the position of the suspended load by the hook 9 can be increased.

That is, a circular rail 1 is attached and fixed to the lower surface of the horizontal member 100, and an electric trolley that turns around on the circular rail 1.
The point that the linear turning rail 2 is suspended by 4 and 4 is the same as in each of the above embodiments. However, when the swing rail 2 is suspended by the electric trolleys 4, 4 as shown in FIG. 22, a horizontal connecting member 2a rigidly connecting the upper flanges of the two swing rails 2, 2 is provided below the trolley yoke. Kansasipine
It is suspended and supported via 35,35. The drive wheels of the electric trolley 4 ride on the upper surface of the lower flange of the circular rail 1 and travel. On the other hand, the electric trolley 5 on the right end side in FIG. 20 on which the slide rail 3 is suspended, as shown in FIG. 23, rotationally drives the drive wheels on the upper surface of the lower flange of the swing rail 2 by a motor with a brake. At the lower part of the trolley yoke of the electric trolley 5 configured as described above, a horizontal connecting member 3a of the slide rail 3 is suspended and supported via a suspension fitting 38. This horizontal connecting material 3a is composed of two turning rails 2,
It is much longer (about 1.9m) than the spacing of about 2 (about 90cm), and two slide rails 3,3
Are placed parallel to the swing rail 2 at an interval of about 1.6 m, and are mounted at substantially the same height and rigidly connected. On the other hand, the electric trolley 50 on the left side in FIG. 20, as shown in FIG. 21, also serves as a horizontal connecting member for the swing rails 2, 2 and is approximately the same as the circular rail 1 above the swing rails 2, 2. An inverted electric trolley is provided in which an upper portion of a trolley yoke is connected to both ends of a long horizontal connecting member 3b provided at a height position and suspended and supported. The drive wheels of the inverted electric trolley 50 support the lower surface of the upper flange of the slide rail 3, and the slide rail 3 is suspended so as to run freely.

Therefore, the slide rail 3 moves the left end out of the turning range (the outer peripheral edge of the circular rail 1) as shown in FIG. 20 by the forward, reverse, and stop operations under the synchronous control of the two front and rear electric trolleys 5, 50. That is, it is possible to freely perform the operation of protruding or returning to the turning range, or stopping at an intermediate position. In FIG. 20, the left portion of the horizontal connecting member 3a located at the right end of the slide rail 3 covers almost the entire length of the slide rail 3, and there is no obstacle on the lower flange thereof. Therefore, the hoist 6 (FIG. 21) composed of the combination of the electric trolley 60 having the driving wheels and the electric chain block 61 which rides on the upper surface of the lower flange,
The slide rail 3 is installed so as to be able to travel over substantially the entire length. The range of movement of the suspension hook 9 of the hoist 6 extends over substantially the entire length of the slide rail 3 as in the above embodiments.

As described above, in the sliding type swiveling crane of the present embodiment, since the height positions of the lower flanges of the swivel rail 2 and the slide rail 3 are almost the same, for example, the first swivel crane shown in FIGS.
When compared with the swing crane of the embodiment, the height position of the traveling wheel of the hoist 6 (the electric trolley 60 thereof) is set at the height of the slide rail 3 (about 300 mm).
The height is about 42 cm, which is the sum of the vertical distance between the swing rail 2 and the swing rail 2 (about 120 mm). Therefore, for example, as shown in Fig. 20, the steel beam 101 lifted from below is
02 When transporting horizontally, etc. on the
Even when the height of the crane is not so large, the crane operation with a considerable degree of freedom (not so cramped) can be performed as compared with the crane of the first embodiment.

Incidentally, referring to FIGS. 19 and 20, the manner of crane work will be described.
When the hoist 103 is suspended at two points by two hoists 6,6, the position of each hoist 6,6 on the slide rail 3 is adjusted in the front-rear direction as shown in FIG. The attitude control can be performed so that the direction of the beam, in particular, the direction of the beam shape matches the direction of the beam and the girder in the building 200.

Different Use Modes (Part 1) FIG. 25 shows a sliding-type swiveling crane for use in building construction and as a crane having a function of moving vertically. In short, as the horizontal member in this case, a girder that rises prior to the construction of the building or a girder member 111 of the work stage is used. Then, a gantry 106 is installed on the top of the column 105, and several jacks 107, 1 installed vertically downward on the gantry 106
At the lower end of the long piston rod 108 of 07, the above-mentioned beam member 111 is connected.

Therefore, when the piston rod 108 is raised (or lowered) under the control of the jack 107, the slide type swiveling crane can be moved up (or down) together with the beam member 111, and the vertical movement function of the crane can be achieved. Can be given.

(Part 2) When used for building construction as shown in FIG. 25, a known tower crane is arranged based on the shape and size of the building plane 200 as shown in FIG. Similarly, the turning range d and the crane working range D
By properly arranging a plurality of different types of sliding slewing cranes, it is possible to implement the embodiment in such a manner as to cover crane operations in all areas of the building plane 200.

(Part 3) FIGS. 27 and 28 show an embodiment in which a slide-type swiveling crane is used for distribution in a warehouse or a factory. Ceiling beams 110 for buildings 201 such as warehouses
Is used as a horizontal member, and a circular rail 1 is attached and fixed to the lower surface thereof.

In particular, in the case of the illustrated example, the slide rail 3 is arranged so as to protrude from the opening 202 on the side wall of the building 201 by an appropriate length, and lifts the luggage 18 outside the building, for example, on the ground to lift the building 20
It is also possible to bring it into 1 and drop it down to the belt conveyor 38 installed on this floor 203 in the building, or drop it on the carriage 40 on the next lower floor 204 through the opening 205 of this floor 203, etc. ing.

In short, the sliding-type swiveling crane of the present invention can be implemented in various usage modes depending on the application target or conditions.

Advantageous Effects of the Present Invention The sliding type swiveling crane according to the present invention has, in addition to the lifting function and the swiveling function that the existing various cranes have,
A crane operation range is provided on the outer periphery of the turning range d, which is extended by the length of the slide rail 3 protruding, so that crane operation in an extremely wide range is possible. Therefore, for example, as shown in FIG.
This contributes to reducing the number of cranes when covering all zeros.

In addition, since it has a sliding function, the crane operation near the center of rotation can be performed with exactly the same degree of freedom as other parts. The frequency of use of the function is reduced, and the crane operation from the end to the end on the diameter line within the crane operation range D can be performed quickly, and the operability and the operation efficiency are excellent.

In addition, the slide-type swiveling crane of the present invention can be constructed and used so that the height from the circular rail 1 to the slide rail 3 is in a range of about 60 cm to at most 1.3 m. It is very convenient for use in

In addition, this slide type swiveling crane can be installed and used under the girders on each floor of the building, and can be installed and used under the ceiling beams in warehouses and factories.
It has the features of being rich in variations of usage modes and having a very wide application range.
