Description

Technical Field

[0001] This utility model belongs to the technical field of high-speed railway rebar binding, specifically relating to a beam rebar binding jig. Background Technology

[0002] High-speed railway construction mainly focuses on prestressed concrete simply supported box girder bridges and continuous box girder bridges. With the rapid development of high-speed railways and the increase in mechanization, the prefabrication technology for standard span simply supported box girders has become increasingly mature. In the prefabrication process of standard span simply supported box girders, a large amount of steel reinforcement is required. The processes of steel reinforcement binding, straightening, handling, and positioning all require a significant amount of manpower, resulting in low efficiency and significant safety hazards. Furthermore, existing steel reinforcement feeding methods require the use of overhead cranes or other hoisting devices to move long steel bars over a large area. For long steel bars with small diameter cages, large bending deflections occur during the lifting and transfer of individual bars. Therefore, an improved technical solution is needed to address the shortcomings of existing technologies. Utility Model Content

[0023] The present invention will now be described in detail with reference to the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features described herein can be combined with each other.

[0024] like Figure 1-3As shown, a beam rebar tying jig includes a storage platform 1, a hoisting mechanism, a rebar straightening and cutting machine 7, and a rebar coil storage rack 8. The rebar straightening and cutting machine 7 and the rebar coil storage rack 8 are conventional commercially available products. The storage platform 1 has a rectangular structure, with two rebar tying jigs 4 on each side of the storage platform 1. The rebar tying jigs 4 on both sides of the storage platform 1 are symmetrically arranged. The platform surface of the storage platform 1 is at the same level as the upper edge of the rebar tying jig 4, so that the platform surface of the storage platform 1 is flush with the upper edge of the jig, ensuring that the rebar can be rolled to the rebar tying jig 4, thereby minimizing the hoisting requirements. A loading station is reserved between each set of jigs. The loading station is located between the two rebar tying jigs 4 on the same side of the storage platform 1. The loading station allows a forklift to move the rebar coil to below the hoisting mechanism, and then the hoisting mechanism is used to hoist the rebar coil to the rebar coil storage rack 8 for loading. Two sets of hoisting jigs are used for loading. The lifting mechanism is set on both sides of the storage platform 1, so that the two sets of steel bar binding jigs 4 on both sides of the storage platform 1 can be loaded. The lifting mechanism includes a main truss 3 and a overhead rail 2. The main truss 3 is a crane beam, which is not limited here. The overhead rail 2 is an I-beam. Multiple support columns 5 are set below the overhead rail 2 to support the overhead rail 2 at a certain height. At both ends of the main truss 3, there are corresponding drive wheels for the overhead rail 2. The two ends of the overhead rail 2 extend between the two steel bar binding jigs 4. The overhead rail 2 extends along the length of the storage platform 1, so that the two steel bar binding jigs 4 on the same side of the lifting mechanism can slide between them. At the same time, the stirrups of the box girder can also be lifted. On both sides of the storage platform 1, there is a set of steel bar straightening and cutting machine 7 and steel bar coil storage rack 8, which can realize the production of continuous steel bars. The integrated setting reduces the need for excessive lifting of continuous steel bars, thereby reducing the possibility of deformation of continuous steel bars.

[0025] On the same side of the storage platform 1, the rebar straightening and cutting machine 7 has a conveyor frame that extends from one of the rebar binding jigs 4. The length of the conveyor frame is adapted to that of one of the rebar binding jigs 4. A stop for the corresponding continuous rebar is provided above the end of the conveyor frame away from the rebar straightening and cutting machine 7, so that the continuous rebar can be directly positioned. Then, the continuous rebar can be placed to the designated position manually or by hoisting, thereby reducing the hoisting distance of the continuous rebar.

[0026] The storage platform 1 is equipped with a conveyor rail 9 parallel to the conveyor frame and corresponding to two rebar binding jigs 4. The straightened long rebar on the conveyor frame is transferred to the conveyor rail 9, and the straightened long rebar is transferred in the opposite direction to the rebar binding jig 4 away from the conveyor frame's conveying direction through the conveyor rail 9.

[0027] In an optional embodiment, the length of the conveyor rail 9 is adapted to the length of the storage platform 1, and a stop is provided at the end away from the rebar conveying direction of the rebar straightening and cutting machine 7, so as to prevent the continuous rebar from falling out of the conveyor rail 9.

[0028] In an optional embodiment, one end of the storage platform 1 is provided with a climbing ramp or climbing frame.

[0029] Two overhead rails 2 are provided on each side of the storage platform 1. The two ends of the main truss 3 of the hoisting mechanism are slidably mounted on the two overhead rails 2 via drive wheels. One of the overhead rails 2 of the two hoisting mechanisms is distributed side by side in the middle of the storage platform 1. The distance between the two overhead rails 2 on both sides of the storage platform 1 is adapted to the width of the steel bar binding jig 4. The drive wheels are connected to the first drive motor, which is a servo motor. A winch is provided on the main truss 3. For specific control and structure, refer to the existing overhead crane or gantry crane. No excessive restrictions are placed on the structure of the hoisting mechanism here.

[0030] Furthermore, two main trusses 3 are installed between the two overhead rails 2 on the same side of the storage platform 1, so as to hoist the two ends of the continuous steel bar and reduce the deformation of the continuous steel bar during the hoisting process.

[0031] In an optional embodiment, the conveyor frame includes a main frame 6 and a first drive roller 10. The main frame 6 is a square frame, and a plurality of first drive rollers 10 are evenly distributed on its upper part in the direction of movement of the continuous steel bar. The two ends of the first drive rollers 10 are rotatably mounted on the main frame 6 through a rotating shaft. The plurality of first drive rollers 10 are connected by a conveyor chain and then synchronously driven by a second drive motor to realize the driving of the continuous steel bar.

[0032] The conveyor rail 9 is located on the side of the main frame 6 away from the steel bar binding frame 4. The conveyor rail 9 is a U-shaped groove. Multiple second drive rollers 12 are rotatably mounted inside the conveyor rail 9. The second drive rollers 12 are rotatably connected to the conveyor rail 9 through a rotating shaft. The multiple second drive rollers 12 are connected to the conveyor chain and then connected to the third drive motor.

[0033] The conveyor rail 9 is close to and lower than the conveyor frame. Support legs 11 are hinged on both sides below the main frame 6. Multiple support legs 11 are evenly distributed on both sides of the main frame 6. The support legs 11 on the side of the main frame 6 away from the conveyor rail 9 are hydraulic rods. Multiple hydraulic rods are driven synchronously to lift and rotate the continuous steel bar above the main frame 6 toward the conveyor rail 9 or the steel bar binding frame 4. The hydraulic rods extend to rotate the conveyor frame toward the conveyor rail 9, and then the continuous steel bar is rotated to the conveyor rail 9, thus realizing the transmission of the continuous steel bar. Furthermore, the hydraulic rods shorten to rotate the conveyor frame toward the steel bar binding frame 4, thereby unloading the continuous steel bar onto the steel bar binding frame 4.

[0034] In one optional embodiment, a plurality of support columns 5 are provided below the overhead rail 2. The support column 5 of the material storage platform 1 is fixed to the ground after passing through the material storage platform 1. The conveyor rail 9 is fixed to the support column 5. The side of the conveyor rail 9 near the support column 5 is provided with inclined stop members to prevent the long steel bar from entering between the conveyor rail 9 and the support column 5. A support arm is provided below the conveyor rail 9, and the support arm fixes the support column 5 by diagonal bracing.

[0035] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model shall be within the scope of protection of the pending claims of the present utility model.
