[0002] At present, the traditional transportation method of combined steel skeleton in highway prefabricated box beam is completed by workers and mechanical devices, including batch storage, transportation, lifting and placement, which has the following disadvantages:

[0003] (1) Traditional transfer mechanical devices use mechanical grippers or grabbing robots for transfer and storage, but the device can only transfer 3-4 steel bars at a time, the transfer efficiency is low, and the transfer mechanical device is easily damaged.

[0004] (2) The transportation and unloading of the composite steel bar skeletons are all carried out by workers. The batch storage, transportation, lifting and placement of the composite steel bar skeletons are very labor-intensive, and safety accidents are prone to occur during the lifting and transportation process.

[0005] Chinese invention patent CN113788413A discloses a stable hoisting device for highway steel box girders and a hoisting construction method thereof, including a first carrier and a second carrier, a workbench is provided on the first carrier, and a main turntable that can rotate horizontally is installed on the workbench through a bearing. Its hoisting method includes the steps of equipment placement, hoisting preparation, hoisting, and adjusting and lowering the steel box girder. In terms of safety, since the hoisting of the combined steel bar skeleton requires hoisting equipment, there are certain operational risks; in terms of quality, since the combined steel bar skeleton includes the steel bars of the bottom plate and the web top plate of the secondary beam and the hollow slab beam, the structure is relatively complex, and it is difficult to ensure the positioning accuracy on the tire frame during laying, and there are certain quality risks; in terms of construction efficiency, the combined steel bar skeleton is hoisted by hoisting equipment, which is time-consuming and inefficient, affecting the efficiency and quality of steel bar transportation and blanking, resulting in a large amount of rework and time costs.

[0006] Chinese invention patent CN112027713A discloses a steel bar transfer device, comprising two quarter-circular arc-shaped slide rails arranged side by side and opening toward the upper right, a superior arc plate coaxial with the superior arc plate is provided on the inner side of the two slide rails, an oblique incision is provided on the right side of the superior arc plate, the front end of the incision is higher than the rear end, a plurality of baffles are evenly distributed along the axial interval on the end of the inner arc surface of the superior arc plate close to the incision, the baffles are detachably installed in the superior arc plate and the free end of the baffle is inclined away from the opening position of the superior arc plate, an arc-shaped rack coaxial with the superior arc plate is fixed on the outer arc surface of the superior arc plate, a gear driven by a motor and meshing with the arc-shaped rack is fixed on the upper left side of the frame, a bracket extending horizontally forward is fixed on the front end of the frame, a vertical electric push rod is fixed on the front end of the bracket, an L-shaped rod is fixed on the protruding end of the electric push rod, the cross bar end of the L-shaped rod is fixed to the protruding end of the electric push rod, and an electromagnet is connected to the vertical pipe end. The device is only suitable for stirrups of a certain size or type; if the specifications of the steel bars vary greatly, the tool may not be able to adapt to all situations, requiring additional adjustments or tool replacement. And because the magnet can only absorb one steel bar at a time, the entire device has low operating efficiency, and the operator may need to spend extra time adjusting the tool, which greatly affects the transfer efficiency.

[0007] Therefore, it is necessary to provide a transport and distribution rack for the composite steel bar skeleton of the highway prefabricated box girder, which can solve the problem of inefficient transport and distribution of the composite steel bar skeleton of the highway prefabricated box girder in the prior art.

DETAILED DESCRIPTION

[0028] The utility model is further described below in conjunction with the accompanying drawings and specific embodiments.

[0029] Please see attached Figure 1 and attached Figure 5 A transfer material distribution frame for a composite steel bar skeleton of a highway prefabricated box girder comprises a tire frame 1, a material distribution mechanism 2 and a transfer vehicle frame 4; the tire frame 1 is a U-shaped structure and is arranged on the ground, and a plurality of auxiliary positioning slots 15 are formed at intervals on the tire frame 1, so that a composite steel bar skeleton 10 can be matched and clamped in the auxiliary positioning slots 15 and the material is distributed in the tire frame 1 at intervals; the transfer vehicle frame 4 is a door-shaped structure, and the transfer vehicle frame 4 is movably arranged on the ground, so that the tire frame 1 passes through the door-shaped space of the transfer vehicle frame 4; a plurality of composite steel bar skeletons 10 are respectively hung on the material distribution mechanism 2, and the material distribution mechanism 2 is arranged on the top of the transfer vehicle frame 4, so that the lower part of the composite steel bar skeleton 10 extends into the U-shaped space of the tire frame 1 and is located directly above the auxiliary positioning slots 15.

[0030] Since the combined steel bar skeleton 10 is a U-shaped structure that is wide at the top and narrow at the bottom, the shape of the tire frame 1 is also a quasi-U-shaped structure, and the tire frame 1 can be adaptively selected according to the actual material distribution requirements of the combined steel bar skeleton 10. Preferably, notches are provided at the bottom, both sides and the top of the tire frame 1 to form auxiliary positioning slots 15, which are used to accurately position the combined steel bar skeleton 10 from the bottom, both sides and the top to ensure the material distribution accuracy of the combined steel bar skeleton 10.

[0031] The transfer vehicle frame 4 can be customized into a door-type structure according to the shape of the tire frame 1, and is used to move along the length direction of the tire frame 1, that is, the material laying direction, and at the same time drive the material laying mechanism 2 installed on the transfer vehicle frame 4 to move synchronously. The material laying mechanism 2 is used to drive the combined steel bar skeleton 10 to move and release it into the auxiliary positioning slot 15 of the tire frame 1.

[0032] Please see attached Figure 4 The transfer vehicle frame 4 includes a material distribution frame 11, a second servo motor 12 and a transfer wheel 13; the material distribution frame 11 is a door-shaped structure, the transfer wheel 13 is installed at the bottom of the material distribution frame 11, the second servo motor 12 is installed on the material distribution frame 11, and the output shaft of the second servo motor 12 is coaxially fixedly connected with the wheel axle of the transfer wheel 13; the material distribution mechanism 2 is installed on the material distribution frame 11.

[0033] Preferably, the material distribution frame 11 can be made of square steel by welding, the cross section of the material distribution frame 11 is a gate-shaped structure, and the length of the material distribution frame 11 can be adaptively adjusted according to actual use requirements. The number of transfer wheels 13 and their arrangement spacing can be adaptively adjusted according to the size and load-bearing requirements of the material distribution frame 11, and the number of second servo motors 12 can be adaptively adjusted according to the required driving force to ensure that the transfer wheels 13 can drive the material distribution frame 11 and the combined steel frame 10 to move synchronously.

[0034] Please see attached Figure 2The material distribution mechanism 2 includes a sprocket chain mechanism 5, a hook 6 and a first servo motor 7; a pair of sprocket chain mechanisms 5 are respectively installed on the top of the material distribution frame 11 along the travel direction of the transfer vehicle frame 4, a pair of first servo motors 7 are respectively installed on the material distribution frame 11 beside the pair of sprocket chain mechanisms 5, and the output shafts of the pair of first servo motors 7 are respectively coaxially fixedly connected with the sprockets of the sprocket chain mechanism 5; a plurality of hooks 6 are respectively arranged on the pair of sprocket chain mechanisms 5 at intervals, and the hooks 6 can hang the combined steel bar skeleton 10.

[0035] The movement direction of the sprocket chain mechanism 5 is annular, and the hook 6 is arranged on the sprocket chain mechanism 5 and moves synchronously therewith. When the hook 6 moves to the sprocket position of the sprocket chain mechanism 5, it turns to change the movement direction, so that the hook 6 can hook the combined steel bar skeleton 10 through the hook structure at its end, which is convenient for the loading of the combined steel bar skeleton 10, and can also release the combined steel bar skeleton 10 after the hook structure is inverted, which is convenient for the laying of the combined steel bar skeleton 10.

[0036] When the hook 6 hangs the combined steel frame 10, the combined steel frame 10 is arranged in parallel just above the auxiliary positioning slot 15, which is conducive to the falling of the combined steel frame 10, and the combined steel frame 10 will not collide with the tire frame 1 when moving with the hook 6.

[0037] Please see attached Figure 2 The sprocket chain mechanism 5 includes a pair of sprockets and a transmission chain. The pair of sprockets are respectively installed at the top ends of the material distribution frame 11 through wheel axles. The transmission chain is annular in structure and is transmission-connected between the pair of sprockets. A hook 6 is connected to the roller of the transmission chain by bolts.

[0038] Please see attached Figure 2 Several of the hooks 6 are distributed on half of the chain rollers along the length direction of the sprocket chain mechanism 5. The number and arrangement spacing of the hooks 6 can be adaptively adjusted according to actual material distribution needs, which is conducive to orderly circulation of material distribution.

[0039] Please see attached Figure 4 A pair of transfer rails 14 are arranged on the ground at the bottom of the material distribution frame 11, and the pair of transfer rails 14 are symmetrically arranged on both sides of the tire frame 1, so that the material distribution frame 11 can be movably mounted on the upper outer side of the tire frame 1 along the length direction of the tire frame 1.

[0040] The transfer track 14 matches the transfer wheel 13, and is used to limit and guide the rolling trajectory of the transfer wheel 13, thereby ensuring the movement stability, safety and controllability of the material distribution frame 11 and the combined steel bar skeleton 10, and preventing them from overturning or derailing.

[0041] Please see attached Figure 1A manual auxiliary operation platform 3 is installed at one end of the top of the material distribution frame 11, and the lower part of the manual auxiliary operation platform 3 is located in the U-shaped space of the tire frame 1.

[0042] The manual auxiliary operation platform 3 moves synchronously with the material distribution frame 11 . The manual auxiliary operation platform 3 can perform manual auxiliary adjustment on the combined steel bar skeleton 10 when the material distribution of the combined steel bar skeleton 10 is inaccurate, so as to ensure the material distribution accuracy of the combined steel bar skeleton 10 .

[0043] Please see attached Figure 3 The manual auxiliary operation platform 3 includes an auxiliary operation bracket 8, the upper end of the auxiliary operation bracket 8 is fixed on the material distribution frame 11, and the auxiliary operation bracket 8 extends downward into the U-shaped space of the tire frame 1 and is higher than the bottom of the combined steel frame 10 in the auxiliary positioning slot 15.

[0044] The auxiliary operation bracket 8 can be designed to be a U-shaped structure smaller than the combined steel frame 10, so that it can pass through the U-shaped space of the tire frame 1 when moving with the material distribution frame 11. The size of the auxiliary operation bracket 8 is suitable for construction workers to stand without colliding with the tire frame 1. Preferably, the auxiliary operation bracket 8 can be made of square steel pipes, steel plates, etc. and welded and fixed on the material distribution frame 11 and located at the position where the chain turns, that is, the position where the combined steel frame 10 falls, so as to facilitate manual inspection and auxiliary adjustment of the falling condition of the combined steel frame 10.

[0045] Please see attached Figure 3 The manual auxiliary operation platform 3 also includes an armrest 9, which is fixedly welded to the material distribution frame 11.

[0046] The handrail 9 can be directly welded to the material placing frame 11 , so that the construction personnel can get on and off the auxiliary operation bracket 8 and keep stable on the auxiliary operation bracket 8 .

[0047] Please see attached Figure 1 To Attachment Figure 5 , the working process and working principle of the utility model are:

[0048] A U-shaped tire frame 1 is set on the ground. The shape and size of the tire frame 1 are adaptively selected according to the shape and size of the combined steel bar skeleton 10 and the amount of fabric. A plurality of auxiliary positioning slots 15 are arranged on the tire frame 1 according to the spacing of the fabrics, which are used to position the combined steel bar skeleton 10, thereby ensuring the fabric accuracy of the combined steel bar skeleton 10 on the tire frame 1.

[0049] A pair of transfer rails 14 are symmetrically arranged on the ground on both sides of the tire frame 1, and a pair of transfer rails 14 are arranged along the material-laying direction of the tire frame 1, that is, the running direction of the transfer vehicle frame 4, so that the transfer vehicle frame 4 can be guided and limited along the material-laying direction through a pair of transfer rails 14 and transfer wheels 13, ensuring that the operation of the transfer vehicle frame 4 is stable and controllable.

[0050] After the second servo motor 12 is started, it can drive the transfer wheel 13 to rotate through the output shaft to provide power for the movement of the material distribution frame 11. The material distribution frame 11 can be made according to the size adaptability of the combined steel frame 10 to ensure that the material distribution frame 11 and the material distribution mechanism 2 and the manual auxiliary operation platform 3 installed on the material distribution frame 11 will not collide with the tire frame 1. The material distribution frame 11 passes from the outside and above the tire frame 1 during the movement, and the combined steel frame 10 and the manual auxiliary operation platform 3 hung on the material distribution mechanism 2 pass through the U-shaped space of the tire frame 1 during the movement.

[0051] After the first servo motor 7 is started, the sprocket of the sprocket chain mechanism 5 can be driven to rotate through the output shaft, thereby driving the transmission chain to make a circular motion through the sprocket, and then the transmission chain drives the hook 6 to move along the fabric direction. The composite steel skeleton 10 is hung on the hook 6. When the hook 6 rotates to the sprocket position, the hook 6 turns with the chain, so that the composite steel skeleton 10 falls to the tire frame 1 below. The moving speed of the hook 6 can be controlled to match the spacing of the auxiliary positioning slot 15, so that when the hook 6 turns to release the composite steel skeleton 10, the composite steel skeleton 10 can fall into the auxiliary positioning slot 15 of the tire frame 1, ensuring the positioning accuracy.

[0052] The construction workers can stand on the auxiliary operation bracket 8. If the combined steel bar skeleton 10 does not fall accurately into the auxiliary positioning slot 15 of the tire frame 1, the construction workers can manually adjust the combined steel bar skeleton 10 into the auxiliary positioning slot 15 to further ensure the laying accuracy.

[0053] As the material distribution frame 11 moves along the material distribution direction of the tire frame 1, the material distribution frame 11 controls the hook 6 through the sprocket chain mechanism 5 to release the combined steel bar skeleton 10 one by one into the auxiliary positioning slot 15 of the tire frame 1, thereby completing the mechanized and automatic material distribution of the combined steel bar skeleton 10, basically without the need for human intervention, and can improve the material distribution efficiency of the combined steel bar skeleton 10 by more than 20%.

[0054] The above are only preferred embodiments of the present invention and are not intended to limit the scope of protection of the present invention. Therefore, any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
