Description

  The present invention relates to a cargo handling device that suspends and conveys a turbine or other large machine / device to a predetermined position, and a cargo handling suspension used therefor. The large machine is conveyed from a predetermined conveyance area to a work area. The present invention relates to an improvement in a lifting structure that supports a suspended article in a state suitable for work in an area.

  Generally, a heavy lifting structure that transports a large heavy load such as a turbine for power generation to a predetermined work position and holds the large heavy load (hereinafter referred to as “lifted weight”) in this work position in accordance with the work is, for example, a ceiling Widely known as a crane. Such an overhead crane is provided with a pair of left and right traveling rails spaced apart from a building such as a factory, and a girder is bridged between the left and right traveling rails. A trolley is mounted on the transverse rail of the girder, and the lifted material is suspended and moved on the trolley by a pulling member such as a chain via a hoisting machine.

  In the above-described lifting structure, for example, Patent Document 1, a pair of left and right girder is arranged on a building such as a factory, a traverse rail is suspended on this girder, and a trolley is mounted on the traverse rail to suspend a lifted object. A lifting structure for lowering and conveying is disclosed. In this way, the lifting structure that moves the lifted object in both the XY direction in the traveling rail direction and the traverse rail direction can move the lifted object from any position to any position, but the equipment becomes large. There is a known problem that the control operation is complicated. In other words, in order to move the lifted object freely in the XY direction, ceiling structures such as girders and traverse rails must be constructed firmly, and the moving operation becomes complicated. At the same time, when a plurality of lifts are transported continuously at the same time, the operation must be controlled so that the lifts do not interfere with each other.

On the other hand, for example, a lifting structure in which a fixed rail for moving a position is arranged on the ceiling of a building and a lifted object is lifted and supported by a chain from a hoisting machine supported on the rail is also widely known. Therefore, when carrying a plurality of lifted objects into the work area for disassembling / repairing or other work, for example, as shown in FIG. 11, a plurality of fixed (work) rails for supporting the suspended lifts are arranged in parallel. A method is adopted in which the lifted objects are arranged and lifted and supported by a hoisting machine on a work rail such as a trailer. In this way, the lifted material is carried into the work area with a trailer, etc., and the lifted material on the trailer is lifted and supported by a hoisting machine, and then the trailer is moved, and then work such as overhauling is performed to construct a factory or the like. An object can be configured in a relatively simple configuration.
JP-A-5-186182

  As described above, when a large heavy object is carried into the work area and supported by being suspended in a predetermined work posture, the crane structure that transports the rail member in the XY direction as described above includes a building. In addition, there is a problem that the apparatus is large and expensive, and simultaneously transporting a plurality of lifted objects requires further enlargement of the apparatus and complicated transport control.

  In addition, as described above, when a lifted object is carried into the work area by a trailer or the like, there is a problem that a trailer carrying track, particularly a large ground area, is required, resulting in a large installation space. For example, when a large heavy object such as a power generation turbine is carried into a work area, a large installation space is required.

  Therefore, the present inventor transports a large heavy object from a predetermined carry-in area to a work area by means of a transport rail, and by hanging the lifted object on a work rail arranged separately from the transport rail in the work area, the lifting device As a result, it has been found that it is possible to carry a plurality of lifted objects continuously into the work area simultaneously with downsizing and space saving.

  In this case, it is required to suspend and support the lifted object at a position / posture suitable for transport in the carry-in area, and to support the lifted object at a position / posture suitable for repair or disassembly work in the work area. The It is preferable to suspend the lifted object in a balanced manner in the carry-in area and to suspend the lifted object in the work area stably (without shaking). In particular, when a lifted object is divided into a plurality of parts for repair or disassembly, it is required to suspend and support at least different positions of the lifted animal in the carry-in area and the work area.

Therefore, the present invention suspends and conveys an object to be conveyed along a predetermined track from a predetermined carry-in area to a work area, and can lift and support a lifted object in a posture suitable for work in the work area. The main problem is to provide a conveyance method and a cargo handling apparatus with a simple structure at low cost.
It is another object of the present invention to provide a cargo handling and lifting device capable of easily suspending a lifting device for supporting a lifted object to a suspension posture suitable for transportation and a suspension posture suitable for work. It is said.

  The present invention adopts the following configuration in order to achieve the above-mentioned object. First, according to the present invention, a transport rail is laid between a preset carry-in area and a work area in a factory or other building, and the work rail is laid in one or more places in the work area. Then, the object to be transported transported along the transport rail is replaced with the work rail and supported. For this reason, the suspension means for supporting the object to be conveyed on each rail is constituted by a first suspension balance member and a second suspension balance member that are detachable from each other. Then, when moving a to-be-conveyed object along a conveyance rail, the to-be-conveyed object is suspended and supported by the united first suspension balance member and the second suspension balance member, and in the work area, the first suspension balance member, The second suspension balance member is separated, and a plurality of portions of the object to be conveyed are suspended and supported individually. This makes it possible to suspend and support the object to be conveyed at one or two places during conveyance, and to suspend and support the object to be conveyed at two or four or more places at the time of work. Therefore, it is easy to suspend the object to be transported in the carry-in area, and space saving is achieved because no work-in space such as a trailer is required in the work area.

  The work rail is composed of a pair of left and right side rail members that form a pair with a distance in a direction intersecting or parallel to the transport rail, and the pair of side rail members is provided at one location with respect to the transport rail. Or arrange in multiple places. The first suspension balance member and the second suspension balance member are configured in a beam shape (beam shape) that is bridge-supported between the side rail members that form the left and right pairs, and each suspension balance member has a work rail. The lifting connection part to support is arrange | positioned in two places on right and left. As a result, it is possible to separate the first suspension balance member and the second suspension balance member, which are detachable in the work area, and to support a plurality of places of the object to be transported on the work rail.

  The first suspension balance member and the second suspension balance member are connected by a connection pin member in a state of being vertically stacked in the direction of suspension of the object to be conveyed, or connected in a state of being approximately overlapped in the horizontal direction. It is configured to be coupled by a member. In this case, if the upper balance member is suspended and supported by the hoisting machine and the object to be conveyed is suspended and supported by the lower balance member, it is easy to switch to the hoisting machine in the work area. Become.

  Next, a lifting device for cargo handling according to the present invention includes a first suspension balance member, a second suspension balance member, and a connecting pin member that couples the first suspension balance member and the second suspension balance member. Then, a hoisting connection part for connecting to the hoisting machine and a suspension connection part for suspending and supporting the object to be conveyed are provided on the hoisting balance members of the first and second hoisting balance members. One of the first suspension balance member and the second suspension balance member is coupled to the hoisting machine in a coupled state, and the other object is suspended and supported by the other. In addition, a plurality of parts or a plurality of objects to be conveyed can be suspended and supported by the respective suspension connecting portions in a state where they are separated from each other.

  Next, in the material handling method according to the present invention, the object to be conveyed is suspended and supported on one of the first suspension balance member and the second suspension balance member that are detachably coupled, and the work area is moved from a predetermined carry-in area. A carrying-in process for transporting the object to be transported along the transported rail and a first lifting balance member for supporting the object to be suspended are replaced from the transport rail to the work rail laid in the work area. The first suspension step for supporting the suspended object by suspension, and then the first suspension balance member and the second suspension balance member are separated, and the position of the divided second suspension balance member is moved along the conveyance rail. And a second suspending step of suspending and supporting the object to be conveyed by suspending and supporting the second suspended balance member moved to this position on the work rail. Then, the transported object is suspended and transported along the transport rail from a predetermined carry-in area to the work area, and the transported object is hung from the work rail in this work area.

  In the present invention, a transported object is transported from a preset carry-in area to a predetermined work area by a first suspension balance member and a second suspension balance member coupled to each other, and a work rail laid in the work area is provided. Since a plurality of parts of the object to be conveyed are suspended and supported by a plurality of suspension balance members that are divided from each other, the following remarkable effects can be obtained.

  First, in the carry-in area, the object to be transported is supported by being suspended by a first suspension balance member and a second suspension balance member that are combined at one place when the object to be conveyed is short, and at two or more places when it is long. Considering the running stability of the suspension, it is possible to carry the suspension with good balance. At the same time, the object to be transported may be suspended and supported at a location required for transport without considering work such as repair and disassembly, so that the suspension work is easy and the work space for that purpose can be reduced. On the other hand, in the work area, the first suspension balance member and the two suspension balance members are separated to support each of the parts to be transported individually, so that the work can be performed in consideration of shaking during work or disassembly. It is possible to support the suspension optimally according to the conditions.

  Further, in the present invention, the first suspension balance member and the second plurality of suspension balance members are coupled at the time of transportation, and separated and separated at the time of work. Therefore, various suspension balance members are scattered in the transportation area and the work area. It is possible to do orderly work. In particular, when a plurality of work rails are provided in the work area and a plurality of objects to be conveyed are carried in and arranged, the suspended balance member is less likely to be scattered and confused.

  Furthermore, the first and second suspension balance members are joined in a state where they are superposed in the suspension direction, and the upper balance member is wound up and supported, and the object to be conveyed is suspended from the lower balance member. By being configured to be lowered, it is possible to achieve an effect such as easy replacement work at a work position (work area).

  The present invention will be described in detail below based on the preferred embodiments shown in the drawings. FIG. 1 shows an overall layout configuration of a cargo handling apparatus according to the present invention, and FIG. 2 is an explanatory view of a lifting structure for suspending an object to be conveyed on a conveyance rail in the apparatus of FIG. FIG. 3 is an explanatory view showing a state in which the object to be conveyed is suspended from the work rail in the apparatus of FIG. FIG. 4 is an explanatory diagram of a conveyance state in which the object to be conveyed is suspended from the work rail in the apparatus of FIG.

[Overall layout configuration]
The cargo handling and transporting apparatus of the present invention includes a transport rail 20 laid in a carry-in area A of a building 10, a work rail 30 laid in a work area B, a traveling trolley 21 mounted on the transport rail 20, and The hoisting machine 23 is connected to the traveling trolley 21, and the hoisting balance member 40 is supported by the hoisting machine 23.

  The carry-in area A is set, for example, as an area for carrying the object M to be transferred to a factory or other building 10 in advance, and a work area B is laid out separately from the carry-in area A. The carry-in area A shown in FIG. 1 is set at one place, and the work area B is set at a plurality of places B1, B2, B3, and B4. Between the carry-in area A and the work area B, a transfer rail 20 for transferring the transfer object M is arranged on the ceiling 11 of the building 10 or the like.

  As shown in FIGS. 1 and 2, the transport rail 20 is arranged along the transfer locus of the transported object M from the carry-in end 20 a of the carry-in area A to the carry-out end 20 b of the work area B. For example, a beam (girder) 22 is laid with a section I-shaped steel on the ceiling 11 of the building 10, and a rail surface is formed by a lower flange of the beam 22. The transport rail 20 is arranged as a center rail that runs vertically in the center of the entire area, for example, in a layout design of a factory or the like. The carry-out end 20b of the transfer rail 20 is laid so as to face the work area B. When a plurality of work areas B are laid out as shown in the figure, the carry-out end 20b of the transfer rail 20 branches to each work area. It is configured to transport the transported object M to B1, B2, B3, and B4. A traveling trolley 21 is mounted on the transport rail 20 to suspend and transport the object to be transported M as will be described later. The beam 22 constituting the transport rail 20 may be made of beam steel having an appropriate cross-sectional shape such as a channel steel material having a U-shaped cross section, for example, in addition to the cross-section I-shaped steel. The other transfer rail 20 may be arranged on an elevated track as a crane structure arranged in an appropriate work area separately from the ceiling of the building.

  On the other hand, the work rail 30 is provided in each work area B 1, B 2, B 3, B 4 and is configured to suspend and support the object to be transported M transported along the transport rail 20. Since the work rails 30 provided in each work area B have the same structure, one of them will be described. The work rail 30 is adjacent to the carry-out end 20b of the transport rail 20 arranged to be branched into each work area B, and is arranged so as to form a left-right pair with the carry-out end 20b of the transport rail 20 in the center. That is, the right side rail member 31 is disposed on the right side and the left side rail member 32 is disposed on the left side with the conveyance rail 20 in between, and each is disposed in a direction parallel to the conveyance rail 20. In addition, the left and right side rail members 31 and 32 can be arranged in a direction intersecting (for example, orthogonal to) the transport rail 20.

  The left and right side rail members 31 and 32 are formed to have a strength capable of suspending the object to be conveyed M with beam steel having an appropriate cross-sectional shape. When the left and right side rail members 31, 32 are obstructed when the transported object M is transported to the work area B by the transport rail 20, the elevator 12 is moved up and down to the ceiling 11 (see FIG. 2). ) Therefore, when the work rail 30 has a layout that does not hinder the transfer of the transfer object M, the work rail 30 is fixed and laid on the ceiling 11 without moving up and down.

  As shown in FIG. 2, the right side rail member 31 and the left side rail member 32 described above are arranged in a direction parallel to the transport rail 20 with a distance L1 from the transport rail 20 as a center. The left and right side rail members 31 and 32 form a level difference H with the traveling rail 20 and are arranged on the lower side. The left and right side rail members 31 and 32 are each composed of a right rail set 31a and 31b and a left rail set 32a and 32b having an interval L2. 31c and 32c shown in the figure are reinforcing frame members provided between both rail sets, and the left and right rail sets are integrated to form a robust structure (see FIG. 6A). Thus, the right side rail member 31 arranged on the right side of the transport rail 20 is composed of right rail sets 31a and 31b, and the right hanging frame 31S is connected to the left rail via the first trolley 31T. A left hanging frame 32S is attached to the sets 32a and 32b via a second trolley 32T so as to be movable. The structure of the first trolley 31T and the second trolley 32T will be described later.

  That is, the left and right side rail members 31 and 32 are arranged in the transport direction of the object to be transported M, and the side rail members 31 and 32 are provided with a first trolley 31T and a second trolley 32T (the illustrated one is a manual trolley). ), The right hanging frame 31S and the left hanging frame 32S are attached so as to be movable in the conveying direction. To each of the suspension frames 31S and 32S, traction members 31Y and 32Y for suspending and supporting a suspension balance member (suspender) 40 described later are connected. In particular, the apparatus shown in FIG. 1 is provided with a plurality of (four pairs in the figure) side rail members 31 and 32 in which such hanging frames 31S and 32S form a left-right pair. The number of the suspension frames 31S and 32S is set according to the work suspension position (four in the drawing) of the conveyed object M described later.

  As described above, in the present invention, the side rail members 31 and 32 that form the left and right pairs are laid in the work area B, and the work M that is transported by the transport rail 20 is suspended and suspended on the work rail 30 that is configured by both the rail members. It is characterized by doing. Accordingly, the left and right side rail members 31 and 32 do not necessarily need to be configured by two rail sets, but are configured by a single rail member, and a suspension member (the suspension frame is connected to the single rail member via a trolley. May be attached. However, as shown in the figure, if the rail set having the interval L2 is used, the transported object M can be lifted by the suspension frames 31S and 32S without being shaken or biased in a mechanically stable state.

[Trolley structure of work rail]
Next, the structure of the first trolley 31T and the second trolley 32T will be described. The left and right side rail members 31 and 32 constituting the work rail 30 described above are formed of I-section steel, and the lower flange is used as the rail surfaces 31r and 31q. As shown in FIGS. 6A to 6C, the first trolley 31T and the second trolley 32T mounted on the work rail 30 are configured by, for example, a manual trolley (may be configured as an automatic traveling trolley). . The first trolley 31T is attached to each of the right rail sets 31a and 31b of the right side rail member 31 having the I-shaped cross section (the same applies to the left side rail member 32). As shown in FIG. 6B, the first trolley 31T includes a unit frame 33f having a substantially U-shaped cross section so as to sandwich the rail surfaces 31r and 31q. Then, the left and right guide wheels 33a and 33b are pivotally attached to the unit frame 33f, and the two guide wheels 33a and 33b are engaged with the rail surface 31r. Similarly, one or two guide wheels 33c and 33d are engaged with the rail surface 31q.

  Further, a guide roller 33g that engages with the side surfaces of the rail surfaces 31r and 31q is rotatably supported on the unit frame 33f. Accordingly, the first trolley 31T (the same configuration of the second trolley 32T) is mounted on the rail surfaces 31r and 31q so as to move freely along the right side rail member 31. The right suspension frame 31S described above is coupled to the unit frame 33f by a coupling rod 34, and a pulling member 31Y (shown as a shackle member) is coupled to the suspension frame 31S. Therefore, when the operator pulls the pulling member 31Y, the hanging frame 31S (the same applies to the hanging frame 32S) can be moved along the right side rail member 31 to an arbitrary position. Needless to say, the first trolley 31T and the second trolley 32T described above may be configured to automatically travel with a drive motor in the same manner as the traveling trolley 21 described later.

[Trolley structure of transport rail]
Next, a crane structure that suspends and supports the object to be transported M on the transport rail 20 will be described.
As described above, the beam 22 is arranged in the building 10 along a predetermined track extending from the carry-in area A to the work area B. The beam 22 is provided with rail surfaces 20r and 20q made of, for example, I-shaped steel. Therefore, a trolley 21 that travels in a state in which the object to be transported M is suspended along the transport rail 20 is mounted. Various structures are known as the traveling trolley 21, but the illustrated one is a self-propelled type mounted on the rail surfaces 20r and 20q of the conveying rail 20 having an I-shaped cross section as shown in FIG. 5B. Indicates a trolley.

  In the traveling trolley 21 shown in FIG. 5 (b), a pair of traveling wheels 27a, 27b and 27c, 27d are supported by a unit frame 26 so as to be rotatable about a rotating shaft, and the traveling wheels 27a, 27b are supported by a rail surface 20r. Further, the traveling wheels 27c and 27d are engaged and supported by the rail surface 20q. That is, the unit frame 26 has a U-shaped cross section so as to sandwich the I-shaped rail (conveying rail), and the running wheels 27a, 27b and 27c, 27d are supported by bearings on the opposite side walls of the unit frame 26, respectively. A traveling motor MO1 is mounted on the unit frame 26, and the traveling motor MO1 drives and rotates the rotation shaft of the traveling wheel 27a. 24a and 24b shown in the figure are a pair of left and right guide rollers, which are supported by the unit frame 26 so as to be slidably rotated by engaging with the rail side surface of the transport rail 20. 24c shown is an electrical equipment box. Accordingly, the traveling trolley 21 is mounted on the transport rail 20 by the traveling wheels 27a, 27b, 27c, and 27d, and travels along the rail surfaces 20r and 20q by the traveling motor MO1. The unit frame 26 is connected with a hoisting machine 23 for suspending and supporting the conveyed object M via a connecting rod 23J.

  The hoisting machine 23 is composed of a normal hoist. As shown in FIG. 5B, in the hoisting machine 23, a load sheave 23r is provided on a drive rotating shaft 23x (not shown) supported on a unit frame 23U, and a hoisting motor MO2 is provided on the driving rotating shaft 23x via a reduction gear. The brakes and limit switches (not shown) are built in. The unit frame 23U is connected to the traveling trolley 21 at the top, and a wire chain 25 is engaged with the load sheave 23r. Accordingly, when the hoisting motor MO2 is rotated forward and backward, the drive rotary shaft 23x (not shown) is rotated forward and backward, and the wire chain 25 engaged with the load sheave 23r attached thereto moves up and down. Therefore, a hook 25f is connected to the lower end portion of the wire chain 25, and a hanging balance member 40 described later is latched and supported. 28 in the figure is a chain bucket.

[Explanation of the structure of the lifting balance member (lifter for cargo handling)]
A suspension 40 (suspending balance member) 40 that is suspended from and supported by the hoisting machine 23 of the traveling trolley 21 mounted on the traveling rail 20 will be described. The cargo handling / carrying hanger (suspending balance member; hereinafter the same) 40 according to the present invention is composed of two or more hanging balance members 40A and 40B that can be integrally coupled with each other, and the object to be conveyed M is placed in a predetermined carry-in area A. When transporting from the work area B to the work area B, the transported object M is suspended and supported in a state of being integrally coupled to each other. In the work area B, the suspension balance members 40A and 40B are separated and individually provided. It is characterized by hanging and supporting the part.

  For this reason, the first suspension balance member 40A and the second suspension balance member 40B are integrally connected in a state where (1) the conveyed object M is vertically stacked in the suspension direction shown in FIG. Alternatively, (2) shown in FIG. 2B are integrally connected in a state where they are overlapped in the horizontal direction (left and right). The former case will be described with reference to FIGS. The suspension balance members 40A and 40B are both formed of a beam material that is longer than the distance L1 between the pair of left and right side rail members 31 and 32 described above. That is, the pulling wire (pulling member; hereinafter the same) 31Y of the right hanging frame 31S supported by hanging on the right side rail member 31 and the pulling wire of the left hanging frame 32S supported by hanging on the left side rail member 32 ( The first suspension balance member 40A and the second suspension balance member 40B are configured to have a length that allows the suspension suspension member 40A and the second suspension balance member 40B to be latched (illustration suspension span L3; L3> L1) (see FIG. 2). When the suspension span L3 = L1, the first trolley and the second trolley may each be one inside. As shown in FIG. 2, the upper suspended upper first suspension balance member (hereinafter referred to as “first balance”) 40 </ b> A has a length L <b> 4, and the lower superimposed second suspension balance member (hereinafter referred to as “first balance”). 40B (referred to as “second balance”) is formed to have a length L5, and the length is formed to satisfy L4 <L5. This is because the lifting connection parts 42b and 42c protrude above the left and right ends of the second balance 40B.

  Therefore, the first balance 40A and the second balance 40B are only different in length and connection structure for connecting both, and the other structures are the same, so the first balance 40A will be described, and the second balance 40B has the same reference numeral. A description thereof will be omitted. In the first balance 40A, channel steel members 40a and 40b having a U-shaped cross-section are overlapped with each other and integrally formed by bolting (fastening bolts 41), and three lifting connection members 42a projecting upward are formed between the two steel members. , 42b, 42c are integrally formed in a sandwich shape. The central lifting connecting member 42a located at the center is provided at a position balanced in the center in the length direction of the balance, and is connected to the hoisting machine 23 described above. Further, the right end lifting coupling member 42b located at the right end portion is configured to be hooked on the pulling wire 31Y of the right side rail member 31 described above. Similarly, the left end lifting coupling member 42c located at the left end is configured to be hooked on the pulling wire 32Y of the left side rail member 32 described above.

  Further, the first balance 40A has a suspension connecting member 43a that protrudes downward between the steel materials (the illustrated attachment is provided with a suspension attachment 48 described later to constitute the suspension connecting member 43a). Is provided. The suspended connecting member 43a is arranged at a left-right balanced position at the center in the length direction of the balance, and auxiliary connecting members 43b and 43c are arranged on the left and right. Thus, the illustrated first balance 40A and second balance 40B are formed by superposing two channel steel members 40a and 40b, projecting upwardly from them, a central lifting connection member 42a, a right end lifting connection member 42b, and a left end lifting connection member. 42c protrudes downward from the center, and a suspension connecting member 43a at the center and auxiliary connecting members 43b and 43c on the left and right thereof are fastened by connecting bolts 41, respectively.

  The first balance 40A and the second balance 40B shown in the drawing are different in the following structure. As shown in FIG. 7, the second balance 40B integrally connects the lifting connection member 42a and the suspension connection member 43b with the connection bolt 41 between the channel steel members 40a and 40b. A coupling hole 47 that engages with a coupling pin member (bolt in the drawing) 46 that is continuous with the coupling hole 44 of the central lifting coupling member 42a of the two balances 40B is provided. Then, in a state where the first balance 40A and the second balance 40B shown in FIG. 8 are stacked one above the other, the connection pin member 46 is connected to the connection hole 47 of the first balance 40A and the connection hole 44 of the central lifting connection member 42a of the second balance 40B. By fitting and fastening, the first balance 40A and the second balance 40B are integrally coupled.

Therefore, the first balance 40A is separated and the attachment 48 shown in FIG. 9B is integrally attached to the coupling hole 47 by the connecting pin member 46. As a result, the first balance 40A in a separated state is attached with the suspended connecting member 43a by the attachment 48, and the object to be conveyed can be supported by the suspended connecting member 43a. On the other hand, each connecting member described above is provided with a connecting hole 44. A connecting tool 45 such as a pin shackle is connected to the connecting hole 44 by a bolt 45a.
Although the first balance 40A and the second balance 40B described above are configured by joining two channel steel materials, this may be composed of one steel material, and the connecting members are fastened with bolts. However, it is needless to say that the balance member may be integrally formed by welding or the like.

[Different Aspects of Suspension Balance Structure (Hanging Equipment for Cargo Handling) (Second Embodiment)]
The above-described suspension balance members 40A and 40B can be integrally connected in a state where they are overlapped horizontally (or front and rear) in the horizontal direction, and this mode is shown in FIG. 7B. The illustrated one shows a case where the first balance 40A (the same as the second balance member 40B) is formed by one channel steel, and the central lifting connection member 42a and the right end are formed on the upper surface flange of the channel steel of length L6 in the same manner as described above. The lifting connection member 42b and the left end lifting connection member 42c are formed integrally with a central suspension connection member 43a on the lower surface flange and auxiliary connection members 43b and 43c (not shown) on the left and right sides thereof, respectively. The first balance 40A and the second balance 40B configured as described above are configured in the same structure, and each balance member is integrally coupled with a connecting pin member (bolt) 46 in a state where the first balance 40A and the second balance 40B overlap in the horizontal direction. 40A and 40B are provided with two connecting holes 44 on the left and right. Accordingly, the first balance 40A and the second balance 40B can be integrally coupled and separated individually by the two connecting pin members 46 at the left and right.

  Next, the operation of each configuration will be described.

Accordingly, the changing position is set to a position where the first hanging balance member 40A can be easily changed to the work rail 30 (a position slightly higher than the hanging position).

  Next, the operator operates the hoisting machine 23 to lower the suspension balance set 40 to a position where the first suspension balance member 40A and the second suspension balance member 40B can be easily separated (uncoupled). The transported object M is substantially lifted and supported on the work rail 30 (left and right side rail members 31 and 32) via the second suspension balance member 40B by the lowering operation of the suspension balance set 40 by the hoisting machine 23.

  Therefore, the operator loosens the connecting pin member (bolt) 46 of the suspension balance set 40 and releases the coupling between the first suspension balance member 40A and the second suspension balance member 40B. As a result, the object to be conveyed M is lifted and supported between the second suspension balance member 40B and the work rail 30, and the first suspension balance member 40A is free while being supported by the hoisting machine 23. In this case, in the second embodiment described above, the shackle SK of the hoisting machine 23 is changed from the central lifting connection member 42a of the second suspension balance member 40B to the central lifting connection member 42a of the first suspension balance member 40A. This state is shown in FIG.

  As described above, the first suspension balance member 40A separated from the lifting suspension system of the object to be conveyed M is provided on the object to be conveyed M in the illustrated position by the operator remotely operating the traveling trolley 21. It moves to the position of the adjacent joint members M2J and M (n-1) J. Therefore, the operator connects the right end lifting connection member 42b and the left end lifting connection member 42c of the first lifting balance member 40A to the suspension frames 31S, 32S of the manual trolleys 31T, 32T prepared in the left and right side rails 31, 32 in advance. . At the same time, the central suspension connecting member 43a of the first suspension balance member 40A and the joint members M2J and M (n-1) J of the conveyed object M are connected.

  The auxiliary connection members 43b and 43c are suspended from the joint members M1J to MnJ of the transported object M by a pulling member such as a pulling string simultaneously with the central suspension connection member 43a of the first suspension balance member 40A and the second suspension balance member 40B. By suspending (see FIG. 3), the object M can be prevented from shaking.

  In this way, the transported object M is individually supported by the work rails 30 by suspending the respective units M1, M2,. Therefore, the operator can disassemble the transported object M into, for example, units M1, M2,... Mn in the work area B1, and perform other operations in a stable state. For example, each unit M1, M2,. The position can be moved along 30.
