DETAILED DESCRIPTION OF THE INVENTION

[0009] Hereinafter, a schematic configuration of a deck slab erection device according to one embodiment of the present invention will be described with reference to FIGS. Fig. 1 is a front view illustrating the schematic configuration of a deck slab erection device according to one embodiment of the present invention. Fig. 2 is a plan view illustrating the schematic configuration of the deck slab erection device. Fig. 3 is a conceptual diagram including a cross section seen from the side indicated by arrow III in Fig. 2, illustrating the schematic configuration of the deck slab erection device. Fig. 4 is a conceptual diagram illustrating an example of the schematic configuration of the front support leg and the installation structure of the front support leg of the deck slab erection device according to one embodiment. Fig. 5 is a conceptual diagram illustrating an example of the schematic configuration of the connecting pin (rotating connecting member) and turnbuckle (adjustment member) of the deck slab erection device. In the figures, reference numeral 100 denotes the deck slab erection device, reference numeral 10 denotes the front support leg, reference numeral 20 denotes the rear support leg, reference numeral 30 denotes the upper support, reference numeral 40 denotes the deck slab transport device, and reference numeral 50 denotes the auxiliary trolley (power unit).

[0010] As shown in Figures 1 to 3, the deck erection device 100 is equipped with, for example, two front support legs 10, a rear support leg 20, an upper support body 30, and a deck transporting device 40, and on a road or bridge where a longitudinal gradient is set along the traveling direction X, the front support legs 10 and the rear support legs 20 are installed vertically and the upper support body 30 is installed in accordance with the longitudinal gradient (along the longitudinal gradient), and in this state the deck P can be removed and erected.

[0011] As shown in Figure 3, when viewed from the forward side F toward the rear side R in the traveling direction, the front support leg 10 comprises a left-side front support leg 10A located on the left side and a right-side front support leg 10B located on the right side, and is formed as a pair on the left and right sides, sandwiching the planned deck slab erection area therebetween. As shown in Figures 1 to 4, the front support leg 10 (10A, 10B) includes a front support leg main body 11, a support leg base member 12, an adjustment jack 13, a roller member (moving means) 14, a stopper member 15, and a hydraulic jack 16. Moreover, the rear support leg 20 (20A, 20B) has a rear support leg main body 21 instead of the front support leg main body 11, but is otherwise the same as the front support leg 10 (10A, 10B). The front support leg 10 is disposed on the front side F in the traveling direction, and the rear support leg 20 is disposed on the rear side R in the traveling direction, and both are erected from the installation surface G facing upward in a substantially vertical direction.

[0012] The front support leg body 11 and the rear support leg body 21 are made of, for example, square pipes, and are rod-shaped support bodies having an external shape that is approximately rectangular parallelepiped. In addition, a support leg base member 12 is arranged at the bottom of the front support leg main body 11 and the rear support leg main body 21, and the front support leg main body 11 and the rear support leg main body 21 are connected by an adjustment jack 13, for example, with a screw structure. By adjusting the adjustment jack 13, the distance between the front support leg main body 11, the rear support leg main body 21, and the support leg base member 12 can be changed, making it possible to adjust the height (length) of the front support leg 10 and the rear support leg 20. 3, even if a gradient is formed on the left and right sides, the upper support 30 can be positioned approximately horizontally on the left and right sides by adjusting the adjustment jacks 13. The adjustment jacks 13 may also be used to adjust the front and rear of the traveling direction to correspond to the longitudinal gradient. The front support leg body 11 and the rear support leg body 21 may be configured arbitrarily.

[0013] The roller member (moving means) 14 has, for example, two rollers in the front-to-rear direction and a casing (shown by the two-dot chain line in FIG. 4) in which the two rollers are arranged, and is disposed below the support leg base member 12. The roller member (moving means) 14 is of a trackless type that travels directly on concrete. The deck slab erection device 100 can be moved by moving roller members (moving means) 14 within this track. Here, the upper surface of the track serves as an installation surface G on which the front support leg 10 and the rear support leg 20 are installed. The configuration of the roller member (moving means) 14 can be set arbitrarily, and for example, an endless structure in which a plurality of rollers are connected to a link member by a pin and the plurality of rollers rotates and goes around may be applied.

[0014] In this embodiment, the stopper member 15 is configured, for example, by a disk formed in an approximately circular shape when viewed from above, as shown in Figure 4, and is attached to the rod of a hydraulic jack 16 connected to the lower part of the support leg base member 12, and is positioned between the two rollers that constitute the roller member (moving means) 14 so that the lower surface faces the installation surface G. The rod of the hydraulic jack 16 moves back and forth, causing the stopper member 15 to move up and down. Specifically, when the rod of the hydraulic jack 16 moves forward, the stopper member 15 moves down and comes into contact with the installation surface G, and the roller member (moving means) 14 moves up and moves away from the installation surface G; when the rod moves back, the stopper member 15 moves up and moves away from the installation surface G, and the roller member (moving means) 14 moves down and is placed on the installation surface G. As shown in FIG. 4, the hydraulic jack 16 is preferably connected by a clevis or the like that can change its orientation by swinging, in order to stably install it on an installation surface G that has a vertical slope.

[0015] As shown in FIG. 3, when viewed from the front to the rear in the traveling direction, the upper support body 30 comprises a left frame 30A and a right frame 30B arranged on the left and right sides and extending along the traveling direction (front-to-rear direction), and a front frame 30F and a rear frame 30R arranged on the front side F and rear side R in the traveling direction and extending left and right, and the front frame 30F (30) and the rear frame 30R connect the front side F and rear side R of the left frame 30A and the right frame 30B, respectively, and are formed into a substantially rectangular shape in a plan view. As shown in Figures 1 and 5, the upper support body 30 is disposed below the left frame 30A and the right frame 30B, and is provided with a pair of left and right lower frames 30C extending along the left frame 30A and the right frame 30B, and the lower frames 30C are connected to the left frame 30A and the right frame 30B by a rigid frame structure.

[0016] The upper support 30 also includes a running rail (running track) 31 arranged along the longitudinal direction (front-rear direction). The traveling rail (traveling track) 31 has a generally I-shaped cross section when viewed, for example, along the longitudinal direction (front-to-rear direction), and is configured with two I-beams with a slope formed so that the thickness of the flanges increases as they approach the central web from the ends, and as shown in Figures 2 and 3, the two I-beams are attached to the undersides of the front frame 30F (30) and the rear frame 30R (30) with a predetermined distance between them in the left-right direction.

[0017] As shown in Figures 1 and 5, the upper support body 30 is connected to the upper parts of the front support leg 10 and the rear support leg 20 by a connecting pin (rotating connecting member) 32, and the front support leg 10 and the rear support leg 20 rotate around the connecting pin (rotating connecting member) 32, making it possible to adjust the intersection angle between the front support leg 10 and the rear support leg 20. As a result, with the front support leg 10 and the rear support leg 20 erected vertically relative to the installation surface G, the upper support body 30 can be positioned along the longitudinal gradient of the installation surface G.

[0018] 1 and 5, the upper support body 30 has a lower frame 30C connected to the front support leg 10 and the rear support leg 20 via turnbuckles (adjustment members) 34, for example. The turnbuckle (adjustment member) 34 includes, for example, a bolt member 34A arranged on the front support leg 10 side and the rear support leg 20 side, a bolt member 34B arranged on the lower frame 30C side and having a reverse thread formed with the bolt member 34A, and a connecting body member 34C formed with a female thread that connects the bolt member 34A and the bolt member 34B.

[0019] When the connecting body member 34C is rotated around the axis, the bolt members 34A and 34B move closer to or farther away from each other, adjusting the spacing (distance) between the front support leg 10, the rear support leg 20 and the upper support body 30, thereby enabling the spacing (distance) to be adjusted to accommodate the inclination of the front support leg 10, the rear support leg 20 and the upper support body 30 and to provide stable support.

[0020] As a result, the upper support body 30 rotates around the connecting pin (rotating connecting member) 32, causing the front support leg 10 and the rear support leg 20 to tilt relative to the upper support body 30, thereby adjusting the distance between the front support leg 10, the rear support leg 20 and the lower frame 30C, and the postures of the front support leg 10, the rear support leg 20 and the upper support body 30 can be stably maintained. Note that bolt members 34A and 34B are preferably attached to be swingable using a clevis or the like, as exemplified for bolt member 34A in Fig. 5, since this can easily accommodate the magnitude of the tilt. Note that reference numeral 38 denotes a brace (support member) for reinforcing the deck slab transporting device when it is moved.

[0021] Next, a schematic configuration of a deck slab transportation device according to one embodiment will be described with reference to FIGS. 1 to 3 and 6 to 8. FIG. Fig. 6 is a conceptual diagram showing an example of a deck slab transporting device according to one embodiment, seen from the front, Fig. 7 is a conceptual diagram showing the attachment relationship between the running rail and the running trolley of the deck slab transporting device body, and Fig. 8 is a conceptual diagram showing the attachment relationship between the running rail and the auxiliary trolley (power unit). In the figures, reference numeral 42 indicates the deck slab transporting device body, and reference numeral 50 indicates the auxiliary trolley (power unit).

[0022] As shown in Figure 1, the deck conveying device 40 comprises, for example, a deck conveying device main body 42 and an auxiliary trolley (power unit) 50 connected to the deck conveying device main body 42, and is attached to a running rail (running track) 31. Then, by driving the auxiliary trolley (power unit) 50, the vehicle moves on the traveling rail (traveling track) 31 in the traveling direction X.

[0023] As shown in Figure 3, the deck transport device main body 42 is equipped with, for example, a running trolley 43, a traverse rail (traverse track) 44, a traverse trolley 45, a swivel mechanism 46, a position adjustment rail 47, a position adjustment trolley 48, a lifting device 49, and an auxiliary trolley (power unit) 50, and is attached to the running rail (running track) 31 by the running trolley 43.

[0024] For example, four traveling trolleys 43 are arranged for each of the two I-beams that make up the traveling rail (traveling track) 31. Specifically, two are arranged at each of the front side F and rear side R of each I-beam at a predetermined distance in the front-to-rear direction. Furthermore, these four traveling trolleys 43 each have a power unit (not shown) such as a motor, and are capable of traveling on the traveling rail (traveling track) 31.

[0025] 1 and 2, the traverse rail (traverse track) 44 includes, for example, two I-beams extending along the traverse direction Y. The configuration of the I-beams is similar to that of the traveling rail (traveling track) 31. Specifically, it comprises an I-beam attached to two traveling trolleys 43 arranged on the front side F of the traveling rail (traveling track) 31, and an I-beam attached to two traveling trolleys 43 arranged on the rear side R, and is arranged at a predetermined interval in the traveling direction X.

[0026] For example, two traverse trolleys 45 are attached to each of the two I-beams that make up the traverse rail (traverse track) 44. Specifically, two traverse trolleys 45 are located on the left side of each I-beam, and two traverse trolleys 45 are located on the right side, and the traverse trolleys 45 located on the left and the traverse trolleys 45 located on the right side are arranged at a predetermined interval on each I-beam.

[0027] The turning mechanism 46 is attached to, for example, the base traversing trolley 45, and as shown in Figures 2 and 3, turns around the vertical axis in the direction of arrow R, thereby enabling the suspended deck slab P to rotate around the vertical axis (in the direction of arrow R). The configuration of the turning mechanism 46 can be set as desired.

[0028] The position adjustment rail 47 is composed of, for example, two I-beams attached to a swivel mechanism 46, and these two I-beams can be oriented in any direction that intersects with the running direction X and the lateral direction Y by rotating the swivel mechanism 46 in the direction of arrow R.

[0029] For example, two position adjustment trolleys 48 are attached to each of the two I-beams that make up the position adjustment rail 47 at a predetermined interval in the longitudinal direction, for a total of four position adjustment trolleys 48. Each trolley 48 can move in the travel direction X, the lateral direction Y, and in any direction directed by the turning mechanism 46.

[0030] As shown in Figure 3, the lifting device 49 comprises an electric winch 49A and a deck slab suspension jig 49B attached to the electric winch 49A for stably suspending the deck slab P, and the deck slab P attached to the deck slab suspension jig 49B can be raised and lowered by the electric winch 49A.

[0031] With this configuration, the deck slab transporting device main body 42 can adjust the orientation of the deck slab P in accordance with its position in the traveling direction X and the lateral direction Y, and the orientation (intersection angle) of the planned deck slab installation position relative to the traveling direction that occurs in response to curves set in roads or bridges. As a result, the deck slab P can be removed or installed easily and efficiently.

[0032] The configuration of the deck transport device main body 42 can be set arbitrarily, for example, it may be equipped with any of the running trolley 43, traverse rail (traverse track) 44, traverse trolley 45, swivel mechanism 46, traverse position adjustment rail 47, traverse position adjustment trolley 48, and electric winch (lifting device) 49, or some of the components may be deleted or publicly known components may be added or replaced.

[0033] 6, the auxiliary trolley (power unit) 50 includes, for example, an auxiliary trolley body (power unit body) 51 and a connecting member 52, and the auxiliary trolley body (power unit body) 51 is connected to the traveling trolley 43 via the connecting member 52 and is attached to the traveling rail (traveling track) 31. The auxiliary trolley (power unit) 50 is capable of moving the deck slab transporting device body 42 along the traveling rail (traveling track) 31 by being driven by the auxiliary trolley body (power unit body) 51.

[0034] Next, the schematic configuration of the traveling trolley 43 and the auxiliary trolley (power unit) 50 will be described with reference to FIGS. 7, the traveling trolley 43 includes, for example, upper rollers 43A arranged above the I-beam that constitutes the traveling rail (traveling track) 31, side rollers 43S arranged on both the left and right sides of the I-beam, and lower rollers 43B arranged below the I-beam that constitutes the traveling rail (traveling track) 31. With this configuration, the traveling trolley 43 is guided by the traveling rail (traveling track) 31 without shifting left and right or up and down relative to the traveling rail (traveling track) 31, and can move along the traveling direction X. The traveling trolley 43 has a power unit (not shown) such as a motor, and is capable of traveling on the traveling rail (traveling track) 31 .

[0035] 8, the auxiliary trolley body (power unit body) 51 includes, for example, upper rollers 55A arranged above the I-beam that constitutes the traveling rail (traveling track) 31, side rollers 55S arranged on both the left and right sides of the I-beam, and lower tires (drive wheels) 55B arranged below the I-beam that constitutes the traveling rail (traveling track) 31. In this embodiment, the drive wheels are made of rubber tires.

[0036] The lower tire (drive wheel) 55B is pressed against the underside of the running rail (running track) 31, and the lower tire (drive wheel) 55B and the upper roller 55A are configured to squeeze the running rail (running track) 31, so that the lower tire (drive wheel) 55B can prevent slipping on the running rail (running track) 31 and can stably grip the running rail (running track) 31. As a result, the auxiliary trolley body (power unit body) 51 is stably guided along the running direction X without shifting left and right or up and down relative to the running rail (running track) 31, and can transmit rotational drive.

[0037] Furthermore, the auxiliary trolley body (power unit body) 51 is equipped with a motor 56 and a reducer 57, and when the motor 56 is driven, the rotational driving force reduced by the reducer 57 is transmitted to the lower tires (drive wheels) 55B, causing the lower tires (drive wheels) 55B to rotate, causing the deck slab transporting device 40 to move in the traveling direction X on the traveling rails (traveling tracks) 31 arranged along the longitudinal gradient. The motor 56 is set to an output that enables the deck slab transporting device 40 to travel on the traveling rails (traveling tracks) 31, which have a longitudinal gradient set, in cooperation with the four traveling trolleys 43.

[0038] According to the deck slab erection device 100 of one embodiment, the upper supports 30 are arranged along the longitudinal gradient, so there is no need to significantly adjust the vertical dimensions (heights) of the front support legs 10 and the rear support legs 20, allowing for efficient installation. In addition, the occurrence of a difference in height between the deck slab erection device 100 and the truck on the road surface (installation surface G) is suppressed, making it possible to easily and efficiently load and unload the deck slab P onto the truck.

[0039] Furthermore, since the deck erection device 100 is equipped with an auxiliary trolley (power unit) 50, the deck transport device main body 42 can be moved stably along the inclined running rail (running track) 31 even if the running trolley 43 does not have power or if the motor output of the running trolley 43 is insufficient.

[0040] Furthermore, according to the deck erection device 100, there is no need to set the vertical dimensions (height) of the front support leg 10 and the rear support leg 20 large, so they can be installed in a stable posture, thereby improving the safety of the work.

[0041] Furthermore, according to the deck erection device 100, the deck transport device main body 42 is equipped with a swivel mechanism 46 and a position adjustment rail 47, so that even for a planned deck erection position where a curve is set and the center of the road is offset from the center of the deck erection device 100, the orientation and position of the deck P can be easily adjusted to match the planned deck erection position, thereby enabling the deck P to be removed and erected efficiently.

[0042] The present invention is not limited to the above-described embodiment, and various modifications can be made thereto. For example, in the above embodiment, the front support leg 10 and the rear support leg 20 are rotatably connected to the upper support body 30 by the connecting pin (rotating connecting member) 32, but the configuration for connecting the front support leg 10 and the rear support leg 20 to the upper support body 30 may be set arbitrarily. For example, when connecting the front support leg 10 and the rear support leg 20 to the upper support body 30, instead of the connecting pin (rotating connecting member) 32, they may be connected and fixed using connecting means such as welding or a fastening member.

[0043] Furthermore, in the above embodiment, a case has been described in which turnbuckles (adjustment members) 34 are used to adjust the inclination of the front support legs 10, the rear support legs 20, and the upper support body 30 to correspond to the longitudinal gradient, but the use of adjustment members and the type of adjustment members may be determined arbitrarily. For example, adjustment may be performed using other types of known adjustment members (e.g., adjustment screws or positioning pins) instead of the turnbuckles (adjustment members) 34, or the inclination of the front support legs 10, the rear support legs 20, and the upper support body 30 may be adjusted to correspond to the longitudinal gradient, and then connected and fixed by connecting means such as welding, fastening members, or connecting pins.

[0044] Furthermore, in the above embodiment, the slab transporting device 40 is described as being connected to the slab transporting device main body 42 by the connecting member 52 with the auxiliary trolley (power unit) 50 arranged outside the slab transporting device main body 42, but the power unit may be configured as desired. For example, a configuration without a power unit such as the auxiliary trolley 50 may be used in cases where the longitudinal gradient is small and manual movement is possible, or in cases where movement is performed by a power unit installed outside the slab erection device 100. Alternatively, a configuration may be used in which a power unit that enables the slab transporting device 40 to travel on the traveling rail (traveling track) 31 is integrated into the slab transporting device main body 42 by increasing the motor output of the traveling trolley 43 or by increasing the frictional force between the wheels and the traveling rail (traveling track) 31 (including cases where tires are provided instead of wheels).

[0045] Furthermore, in the above embodiment, the auxiliary trolley (power unit) 50 is described as having a lower tire 55B that is driven to rotate relative to the traveling rail (traveling track) 31, but the driving means for the traveling track can be set arbitrarily, and may be any configuration, such as a rack-and-pinion mechanism in which a driving wheel with a pinion gear is engaged with a traveling track with a rack formed thereon.
