  However, in the configuration described in Patent Document 1, the pair of front and rear bogies mounted on the pair of left and right guide rails laid at the site has no independence and is not stable. A pair of bogies are integrally connected by the bogie interlinking member, and the bogies are first completed, and supports installed at predetermined positions on the bogies, specifically, on each of the front and rear bogies Lifting support columns are erected on the seat portion, and the upper ends of the pair of front and rear lifting guide columns are integrally connected by the inter-support connecting members, and the transfer object support is assembled to complete the transfer traveling body. It was a thing. For this reason, the lifting guide post is vertically mounted on the carriage side from the post mounting seat on the carriage side so that the lower end of the lifting guide post is positioned right above the post mounting seat on the upper surface of the completed carriage. You have to lift it to a high height and move it horizontally. Therefore, not only a crane capable of moving in the X and Y directions at a level higher than the upper end of the lifting guide post of the completed transfer traveling body is required at the installation site of the transfer traveling body, but also as the crane The need for a large crane capable of lifting the entire heavy lifting guide post is a practically impractical solution.

  The present invention proposes a transport traveling body capable of solving the above-mentioned conventional problems, and the transport traveling body according to the present invention understands the relationship with the embodiments described later. For ease of reference, the reference numerals used in the description of the embodiment are shown in parentheses, and the carriage (2) is supported on a pair of left and right guide rails (7) laid along the traveling path. And a lifting guide support (3A) erected on the carriage (2), and a transfer traveling body (5) having a transferable object support (5) which can be lifted and lowered along the lifting guide support (3A) In 1), the carriage (2) includes two carriage portions (8A, 8B) in the traveling direction which can be connected and disconnected mutually, and at least one of the two carriage portions (8A, 8B) is: A train connecting the wheel units (11A, 11B) supported by the pair of left and right guide rails (7) and the wheel units (11A, 11B) A movable body comprising a connecting member (10), and the wheel units (11A, 11B) are mounted so as to be able to seesaw movably at the left and right ends of the connecting member (10) via support shafts (12) concentric with each other. (13) and a pair of front and rear wheels (14a, 14b) pivotally supported on the front and rear sides with respect to the support shaft (12) of the movable body (13), and the elevating guide support (3A) It is mounted on the connecting member (10), and is laid around the support shaft (12) together with the connecting member (10) on a traveling path on the opposite side to the side with the carriage (2) The connection member (10) is configured such that it can freely move up and down between the lying posture and the standing posture and the lifting guide post (3A) is in the standing posture, and the inside of the two carriages (8A, 8B). It is the structure connected with the other trolley | bogie part.

  When the transport traveling body according to the present invention is installed on the travel path of the transport traveling body prepared in advance at the installation site in a factory or the like, at least three of the two bogies constituting the bogie and the elevation guide post Parts are divided into parts and carried into the site, and at this site, of the two bogies placed on the guide rails on the travel path side, the elevating guide post is erected on the bogie on the side where the elevating guide post is erected Work and the work of connecting the two carriages to each other to complete the carriage, but according to the configuration of the present invention, the elevator guide post mounted on the connection member is connected The connecting member before the elevating guide post is attached, since it can be put into a fallen posture on the traveling path opposite to the side with the carriage around the support shaft together with the member. Before Set the sideways posture when lying down, and raise and lower the elevating guide post horizontally on the traveling path so that the lower end mounting portion of the elevating guide post faces the post mounting portion of the connection member in the sideways posture of the carriage. In this state, the lower end mounting portion of the elevation guide support is made to abut on the support mounting portion of the horizontal connection member by connecting the carriage portion and the elevation guide support relatively in this state, and the two are coupled. It can. Thereafter, while raising and lowering the elevating guide support in the fallen posture, for example, by a crane and changing it to a vertical standing posture, the two carriages are moved relatively close to each other, and one carriage equipped with the elevating guide support in the upright posture. By connecting the connecting member of one part to the other bogie part, it is possible to complete a bogie provided with a lift guide post standing upright.

The transportable traveling body according to the present invention, which can be assembled as described above, is vertically lifted with the elevating guide support upright, and the lower end mounting portion of the elevating guide support is lowered to the support mounting portion of the carriage to couple them together. Even if the elevating guide support is a large and heavy transport traveling body as compared to the configuration that must be carried out, the elevating guide support is changed from the inclined posture to the upright posture as a crane required for handling the elevating guide support. Since a small crane that can be used can be used and the installation height of the crane can be lowered, the cost required for the operation can be reduced and the operation itself can be performed easily and safely. Further, in the configuration of the present invention, the carriage portion on which the elevation guide support is erected to increase the load is used as a four-wheel support structure, and the load is distributed to the four wheels to support the elevation guide support stably. A pair of front and rear wheels of the left and right side plates are pivotally supported by movable members capable of seesaw movement, but with this configuration, a horizontal posture for attaching a lifting member and a lifting member is actually provided. Even when the connection member is rotated, the connection member can stably maintain its lateral orientation, so that the mounting of the elevation guide support to the connection member in the lateral orientation can be performed easily and safely. Furthermore, the bearing structure for pivotally supporting on both left and right ends of the connection member of the movable body provided with a pair of front and rear wheels is used for the bearing structure that pivotally supports the elevating guide support, and the elevating guide on the carriage side Since a dedicated bearing structure for pivotally supporting the column is not necessary, the structure is simplified and can be implemented inexpensively and easily.

  Although the present invention can be practiced as a transport traveling body in which the lifting guide support (a single lifting guide support or a pair of left and right lifting guide support) is erected only on one side of the front and rear two carriages. In this case, the other carriage has wheels at the left and right sides of the outer end and has a connecting portion at the inner end with a connecting member on which the elevation guide post of one carriage is erected. In this case, the wheel at the outer end of the other carriage portion may be a pair of left and right two-wheel structure concentrically supported pivotally, and the seesaw movable movable body in one carriage portion back and forth It may be a four-wheel structure comprising a structure supporting a pair of wheels. However, the bogie (2) is composed of two bogies (8A, 8B) in the traveling direction and bogie inter-member connecting members (9A, 9B) for connecting the two bogies (8A, 8B), The two bogies (8A, 8B) in the traveling direction have the same construction as the bogie comprising the pair of left and right wheel units (11A, 11B) and the connecting member (10) connecting the two wheel units (11A, 11B). Preferably, the inter-part connecting members (9A, 9B) are configured to connect the connecting members (10) of the two carriage parts (8A, 8B).

  When it is set as the trolley | bogie of the eight-wheel structure which employ | adopted the said structure, the said trolley | bogie inter-piece connection member (9A, 9B) separates right-and-left both ends of the said connection member (10) of both bogie parts (8A, 8B) separately. A pair of left and right pairs of left and right inter-bogie connecting members (9A, 9B), corresponding to two places in one traveling direction of the inter-bogie connecting member (9A), corresponding one-side guides A steadying roller (36) can be provided which clamps the rail (7). According to this configuration, as compared with the case where the anti-vibration roller sandwiching the guide rail is provided on the movable member on one side of the two carriages (8A, 8B), the anti-vibration roller is the seesaw of the movable member. Not only the inconvenience of sliding the guide rail side in the vertical direction along with the movement can be avoided, but a simple roller unit in which the anti-vibration roller is pivotally supported on the mounting member for the inter-carton connecting member can be used.

  In the case of using the 8-wheel carriage (2) adopting the above configuration, the elevating guide columns (3A, 3B) are respectively placed on the coupling members (10) in the two carriages (8A, 8B) in the traveling direction. There is provided an inter-support connecting member (4) which is erected and connects the upper ends of the pair of front and rear elevation guides (3A, 3B), and the object support base (5) It can be configured to move up and down between the columns (3A, 3B). Further, regardless of which configuration is used, elevation drive means (6A, 6B) are required to raise and lower the object support base (5) along the elevation guide columns (3A, 3B). The lifting drive means (6A, 6B) is fitted and fixed to the connecting member (10) so as to be extractable upward, and the lifting guide post (3A, 3B) is mounted on the upper surface of the lifting drive means (6A, 6B). Can be attached.

  According to this configuration, as compared with the case where the lifting and lowering drive unit is attached to the lifting and lowering guide post after standing vertically, the lifting and lowering drive for the connection member lower than the lifting and lowering guide support The mounting operation of the elevation driving unit can be easily performed regardless of the mounting operation time. In addition, in comparison with the case where the raising and lowering driving unit is attached to the raising and lowering guide support before vertically standing, the lower end of the raising and lowering guide support in the lying posture is attached to the connecting member, and the raising and lowering guide support in the lying posture The weight burden on the work is reduced, and these work can be performed easily and safely. Furthermore, since the elevation driving means fitted and fixed to the connecting member serves as a mounting seat for the elevation guide post, it leads not only to the reduction of the number of parts as compared with the case of separately providing a dedicated column mounting seat, The relative positional relationship between the elevation guide post and the elevation drive means is automatically determined as set as desired, and it becomes easy to reliably perform the operation as set as intended.

  Further, the connecting member (10) is provided with a pair of left and right side frame members (10a, 10b) for supporting the pair of left and right wheel units (11A, 11B) separately, and the both side frame members (10a, 10b) Elevating / lowering drive means (6A, 6B), which are constituted by an outer main coupling member (10c) and an inner sub coupling member (10d) to be coupled, and lifts and lowers the transported object support base (5) (10c) and the sub-connection member (10d) are removably fitted upward and fixed, and the inner sub-connection member (10d) is in contact with the pair of left and right side frame members (10a, 10b) It can be configured to be removable. According to this configuration, it is possible not only to avoid the above-mentioned inconvenience in the case of attaching the elevation drive means to the elevation guide support but also to carry out maintenance and the like from the transport traveling body assembled and in use. Therefore, when it is necessary to remove the sub-connection members constituting the connection member from the side frame members on both the left and right sides, it is possible to remove the lifting and lowering drive means to the inside of the carriage. Of course, when the structure for supporting the elevation guide support on the elevation drive means as described above is adopted, the elevation drive means is removed together with the elevation guide support.

It is connected between the parts 8A and 8B.

  When the connecting members 10 of the pair of front and rear bogies 8A and 8B are integrally connected by the pair of left and right bogie connecting members 9A and 9B as described above and the bogie 2 is completed, the bogie 2 is at its four corners It is movably supported on a pair of left and right guide rails 7 on the traveling path side by the wheel units 11A and 11B positioned and the two roller units 32A and 32B at the front and rear two positions engaged with the guide rails 7 on one side. The wheel units 11A and 11B located at the four corners of the carriage 2 respectively have a pair of front and rear wheels 14a and 14b on the movable body 13 capable of seesaw movement around the fixed support shaft 12 with respect to the carriage 2 (cart units 8A and 8B). Of the four carriages 8A and 8B, so that one of the four wheels 14a and 14b floats from the upper surface of the guide rail 7 That fear is none, the carriage 2, can be run at rattling without a stable state.

  As described above, when the carriage 2 is completed, the upper end portions of the pair of front and rear lift guide supports 3A and 3B are connected by the inter-support connecting member 4, and the object support base 5 is provided between the lift guide supports 3A and 3B. As shown in FIG. 1 and FIG. 2, the transported product supporting base 5 is structured such that the insides of the elevating guide columns 3A and 3B are the elevating guide rails 26 as shown in FIG. 1 and FIG. 2. The left and right two places of the front and rear sides are suspended by a pair of front and rear hanging units 38a and 38b which can be moved up and down along these two lifting units 38a and 38b. Is locked to one end of a pair of left and right pair of vertical drive belts 40a and 40b which are spanned by a pair of left and right guide wheels 39a and 39b pivotally supported on the other side, and the other end of the vertical drive belts 40a and 40b To Lifting guide column 3A, the weight unit 41A is vertically movable furnished in the inner space of the rear release 3B, 41B is suspended. Furthermore, the lower ends of the hanging units 38a and 38b and the lower ends of the weight units 41A and 41B are hung in a U-shape on a pair of left and right drive rotating bodies 19a and 19b of the elevation driving means 6A and 6B. It is connected to the upper end of a pair of left and right pair of front and rear lifting drive belts 18a and 18b. As a result, the lower left and right pair of lifting and lowering drive belts 18a and 18b and the upper left and right pair of lifting and lowering drive belts 40a and 40b are endlessly formed via the hanging units 38a and 38b and the weight units 41A and 41B. Connected Since the weight units 41A and 41B are heavy objects, the elevating guide support columns 3A and 3B are vertically erected on the carriage 2, and then installed in the elevating guide support columns 3A and 3B to lift and lower drive belts 18a, 18b, 40a and 40b can be connected.

  The transport traveling body 1 assembled as described above has the total of eight wheels 14a and 14b synchronized with the eight braked electric motors 16a and 16b directly connected to each other on the guide rails 7. Forward and backward, and can be stopped at a predetermined position, and by operating the electric motors 20a and 20b with the braking function of the elevation driving means 6A and 6B synchronously while the transport traveling body 1 is stopped or traveling. The object support base 5 can be moved up and down in parallel between the raising and lowering guide columns 3A and 3B through the raising and lowering drive belts 18a, 18b, 40a and 40b and the hanging units 38a and 38b. In addition, the to-be-conveyed object transfer means 5a can be installed in the to-be-conveyed object support stand 5 as shown in FIG. Also, although FIGS. 2A and 3 show that the rear side of the elevation guide columns 3A, 3B is released, a cover plate or a frame may be provided on the rear side release portion of the elevation guide columns 3A, 3B as necessary. Etc. can be attached.

  In the assembly work of the transport traveling body 1 described above, the bogies 8A and 8B supported on the guide rails 7 via the wheel units 11A and 11B are unstable in position and orientation in plan view. Because of this, there is a possibility that the operation of rotating the connecting member 10 outward at right angles and the connecting operation of the elevation guide columns 3A and 3B may be adversely affected. In order to solve this problem, as shown in FIGS. 12A and 12B, a pair of left and right first jigs 42 for fixing the wheel units 11A and 11B at the left and right ends of the connecting member 10 to the guide rail 7 is used in combination. Can do. The illustrated first jig 42 is placed on the upper side of the movable body 13 and is attached to the outer side of the horizontal plate 43 that can be detachably attached to the movable body 13 (two T-shaped members 13a and 13b) by a bolt 43a. A vertical plate 44 is fixedly connected by welding or the like along the outside of the central longitudinal portion of the movable body 13 so that the lower end can be positioned on the lateral side of the guide rail 7. And lock the horizontal bolt 44a for narrowing the gap between the guide rail 7 and the lock bolt 45 screwed from the outside of the vertical plate 44 to the pair of front and rear through screw holes provided in the horizontal bar 44a. Is provided.

  The above-mentioned first jig 42 is a movable body 13 (two T-shaped members) of the pair of left and right wheel units 11A and 11B of the carriages 8A and 8B placed at a predetermined position on the guide rail 7 in a predetermined direction If the horizontal plate 43 is placed on the upper surface of 13a and 13b) and fixed to the movable body 13 by the bolt 43a, the horizontal rod 44a inside the lower end of the vertical plate 44 is adjacent to the outer surface of the guide rail 7. Therefore, by tightening the lock bolt 45 in this state and pressing the tip to the side of the guide rail 7, the lock bolt 45 of the pair of left and right first jigs 42 attached to the pair of left and right wheel units 11A and 11B With the left and right guide rails 7 sandwiched from both left and right sides, the left and right wheel units 11A and 11B are fixed at predetermined positions on the guide rails 7 in a predetermined direction. To it can be. Therefore, the operation of rotating the connecting member 10 around the fixed support shaft 12 and the connecting operation of the elevation guide columns 3A and 3B to the connecting member 10 rotated outward at right angles can be performed easily and reliably. Incidentally, inside the vertical plate member 44, a bolt 12b for fixing a retaining circular plate 12a for preventing the movable body 13 (cylindrical bearing 13c) from coming off from the fixed support shaft 12 to the fixed support shaft 12 The head is protruding. Therefore, when providing a circular through hole 44b in the vertical plate 44 to avoid the head of the bolt 12b, it not only helps to reduce the weight of the vertical plate 44, but also prevents the vertical plate 44 from being removed from the circular plate 12a. It can be made to abut on the surface and be stabilized, and the gap between the vertical plate 44 and the guide rail 7 can be narrowed.

  In the case where the vertically elevated and lowered guide columns 3A and 3B are attached to the connecting member 10 of the carriages 8A and 8B, the connecting member 10 is rotated 90 degrees outward at right angles, and in this state, the connecting member 10 is A second jig 46 can be used in combination to prevent rotation around the fixed support shaft 12. As shown in FIGS. 11 to 14B, when the connecting members 10 of the wheel units 11A and 11B fixed to the guide rail 7 by the first jig 42 are rotated 90 degrees outward around the fixed spindle 12 Mounting seats 31a and 31b of the side frame members 10a and 10b at both ends of the connecting member 10 that are laterally oriented inside the wheel units 11A and 11B for connecting the inter-carton connecting members 9A and 9B are the wheel units It will be positioned horizontally at a position higher than the top surfaces of 11A and 11B. The second jig 46 is superimposed on the mounting seat portions 31a and 31b when the connecting member 10 is rotated 90 degrees outward around the fixed support shaft 12, and is detachably fixed by the bolt 47a. A horizontal plate member 47 and a lower horizontal plate member 48 overlaid on the horizontal plate member 43 of the first jig 42 and detachably fixed by a bolt 48 a are connected and integrated in a step-like manner by an intermediate vertical plate member 49. is there.

When the parts 8A and 8B are integrally connected by the inter-carton connecting members 9A and 9B, at least one of the bogies 8A / 8B must be moved closer to the other bogie, so the truck on the side to be moved at this time The first jig 42 must also be removed from the portions 8A / 8B.

  When the carriages 8A and 8B are integrally connected by the carriage connecting members 9A and 9B, the elevating guide columns 3A and 3B must be held in a vertical standing posture with respect to the carriages 8A and 8B. In this case, the third jig 50 shown in FIGS. 15A and 15B can be used. The third jig 50 can be placed on the upper surfaces of the movable bodies 13 (two T-shaped members 13a and 13b) of the pair of left and right wheel units 11A and 11B of the carriages 8A and 8B and fixed by bolts 51a. It can be placed on the upper surface of the connection member 10 in the upright posture (upper surfaces of the side frame members 10a and 10b) when the plate member 51 and the elevation guide columns 3A and 3B are held in the vertical upright posture and fixed by bolts 52a. The lower horizontal plate members 52 are integrally connected by the vertical plate members 53.

  Therefore, in a state where the elevation guide support 3A, 3B is switched to the vertical standing posture with respect to each of the carriage portions 8A, 8B, connection of an upright posture with at least one of the wheel units 11A, 11B of each carriage portion 8A, 8B By connecting the end portions (the side frame members 10a and 10b) of the member 10 with the third jig 50, the elevating guide columns 3A and 3B can be held in the vertical standing posture. By using the third jig 50, the elevating guide support columns 3A and 3B caused in the vertical standing posture can be stably and surely compared with the case where they are held in the vertical standing posture as they are by the crane used for this. The lift guide columns 3A and 3B can be held in the vertical standing posture, and the workability can be improved. The upper horizontal plate member 51 of the third jig 50 can be configured to be able to be stacked and fixed on the horizontal plate member 43 of the first jig 42 used for positioning the carriage portions 8A and 8B. . In this case, the thickness of the horizontal plate 43 of the first jig 42 is set between the lower horizontal plate 52 of the third jig 50 and the upper surface of each end of the connecting member 10 (the upper surfaces of the side frame members 10a and 10b).
