DETAILED DESCRIPTION

[0026] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0027] In order to realize the intelligent storage and intelligent distribution of U-shaped steel bars of railway prefabricated box girders and solve the problems of low construction efficiency and high labor intensity of U-shaped steel bars in the installation process of prefabricated steel bars for railway box girders, the following article provides a steel bar binding jig for railway prefabricated box girders.

[0028] Reference Figure 1-5 The steel bar binding jig includes: a flange plate module 1 and a bottom web plate module 2.

[0029] Figure 1 is a three-dimensional schematic diagram of the connection process of the flange plate module 1 and the bottom web plate module 2, combined with Figure 1 The number of flange plate modules 1 is 1, the number of bottom web plate modules 2 is greater than 1 (usually 8), the bottom web plate module 2 is detachably connected to the flange plate module 1, and a steel bar binding jig is formed after one flange plate module 1 and at least two bottom web plate modules 2 are connected.

[0030] Figure 2 This is a schematic diagram of the transportation and placement process of the flange plate module 1 and the bottom web plate module 2, combined with Figure 2The flange plate module 1 is integrated. After the flange plate module 1 is transported to the steel bar binding pedestal 7 and is in place, it will no longer be moved. The bottom web plate module 2 also serves as a storage and transportation jig for the U-shaped steel bars 4. The bottom web plate module 2 and the U-shaped steel bars 4 stored therein are transported to the side of the steel bar binding pedestal 7, and then the bottom web plate modules 2 are moved one by one to reach the designated position inside or on the side of the flange plate module 1 through the planned path, and then the bottom web plate module 2 is connected to the flange plate module 1 to form an integrated steel bar binding jig. The U-shaped steel bars 4 required for the railway prefabricated box girder are already stored inside the steel bar binding jig, and no manual handling is required, thereby saving a process and greatly reducing the labor intensity at the construction site.

[0031] Figure 3 is a schematic diagram of the bottom web module 2 and the U-shaped steel bars 4 stored therein, combined with Figure 3 The bottom web module 2 includes: a fixture platform 21 and a supporting platform 22 .

[0032] The jig platform 21 includes a plurality of steel bar slots 23 arranged along the length direction of the jig platform 21. The steel bar slots 23 match the shape of the U-shaped steel bar 4. The spacing of the steel bar slots 23 is the same as the spacing of the U-shaped steel bar 4 inside the railway prefabricated box girder. The jig platform 21 is used as a jig for the U-shaped steel bar 4 in the steel bar processing plant.

[0033] The supporting platform 22 is arranged at the bottom or both sides of the jig platform 21. In order to facilitate the transportation of the jig platform 21 by a conveyor, a forklift or an intelligent trolley, the bottom wall of the supporting platform 22 is usually higher than the bottom wall of the jig platform 21, so that the fork rod or the intelligent trolley can move to the bottom of the supporting platform 22.

[0034] Figure 4 It is a plan view of the connection process of the flange plate module 1 and the bottom web plate module 2. Figure 5 This is a schematic diagram of the connection and separation of the flange plate module 1 and the bottom web plate module 2. Figure 4 and Figure 5 One of the flange plate module 1 and the bottom web plate module 2 is connected to a fixed pin shaft 5, and the other is connected to a rotatable clamping plate 6, on which a bayonet is provided. When the clamping plate 6 rotates in one direction, the bayonet is connected to the pin shaft 5, and when the clamping plate 6 rotates in another direction, the bayonet is separated from the pin shaft 5.

[0035] The clamping plate 6 and the pin shaft 5 are arranged in the length direction and the width direction of the flange plate module 1 , so that the flange plate module 1 and the bottom web plate module 2 can be detachably connected in the length direction and the width direction of the flange plate module 1 .

[0036] In addition to the clamping plate 6 and the pin 5, other quick-release structural connections may also be used, such as a latch connection structure, a snap connection structure, a buckle connection structure, a buckle connection structure, a spiral connection structure, and the like.

[0037] Combination Figure 2 Since the position of the flange plate module 1 is limited on the steel bar binding pedestal 7, and the moving trajectory of the bottom web module 2 is also limited between the steel bar forming workshop 8 of the U-shaped steel bar 4 and the steel bar binding pedestal 7, the transportation of the bottom web module 2 can be automated.

[0038] Combination Figure 1 , 2 , 3, 5, 6 The following provides a reinforcement binding system for railway prefabricated box girders.

[0039] Figure 6 It is a three-dimensional diagram of the intelligent transfer vehicle 3, which includes a vehicle body 31, a lifting device 32 and a traveling device 33. The lifting device 32 and the traveling device 33 are respectively installed on the upper and lower sides of the vehicle body 31.

[0040] The vehicle body 31 is installed with one or more of a laser navigation system, a visual navigation system, a magnetic stripe navigation system, an inertial navigation system, and an indoor positioning system. The lifting device 32 adopts a hydraulic cylinder or an electric push rod, and the walking device 33 adopts an electric universal wheel, a four-way shuttle or a crawler.

[0041] Inside the steel bar forming workshop 8, after the U-shaped steel bars 4 are filled with the bottom web module 2, the intelligent transfer cart 3 moves to the bottom of the supporting platform 22, and the jacking device 32 lifts the bottom wall of the supporting platform 22 upward, so that the supporting platform 22 leaves the ground, and then the intelligent transfer cart 3 transports the bottom web module 2 and the U-shaped steel bars 4 inside it through the planned path. After the bottom web module 2 is in place, the jacking device 32 releases the bottom wall of the supporting platform 22 downward, so that the supporting platform 22 contacts the ground, and then the intelligent transfer cart 3 returns to the inside of the steel bar forming workshop 8 through the planned path.

[0042] The workers continue to install other steel bars to complete the binding of the steel cage frame, and then hoist the steel cage frame into the mold of the railway prefabricated box girder, and then release the connection between the clamping plate 6 and the pin shaft 5. The intelligent transfer trolley 3 then transfers the bottom web module 2 to the interior of the steel bar forming workshop 8, so that it moves along the production line to receive the processed U-shaped steel bars 4.

[0043] The above embodiments are only exemplary embodiments of the present invention and are not intended to limit the present invention. The protection scope of the present invention is defined by the claims. Those skilled in the art may make various modifications or equivalent substitutions to the present invention within the essence and protection scope of the present invention, and such modifications or equivalent substitutions shall also be deemed to fall within the protection scope of the present invention.
