Description

Technical Field

[0001] The utility model relates to the technical field of box girder end-anchoring, in particular to a box girder end-anchoring construction device. Background Technique

[0002] A box girder is a concrete structure and one of the important components of a bridge. To improve the construction efficiency of the bridge, box girders are usually precast first and then hoisted onto the piers for installation after completion. The box girder structure includes a bottom plate, a top surface, two side webs and wing plates. Prestressed tendons need to be laid in the two side webs. Usually, corrugated pipes are arranged before pouring. The corrugated pipes are fixed to the web body, and then steel strands are inserted into the corrugated pipes and fixed at both ends with anchor backing plates. The steel strands are prestressed and tensioned. After the tensioning is completed, the steel strands that extend too long at both ends are cut off. Finally, a cylindrical mold is used to surround the anchor backing plates and the steel strands, and concrete slurry is filled in the mold. After the concrete solidifies, the mold is removed, and the anchor backing plates and the steel strands are wrapped and fixed by columnar concrete. This action is called end-anchoring;

[0003] When disassembling the closing plate, due to the large weight of the closing plate and the narrow internal space of the beam box after it is formed, the manual disassembly method requires the cooperation of multiple people. The activity space of the disassembling operators is small, resulting in great difficulty and low efficiency in disassembling the closing plate. Therefore, a box girder end-anchoring construction device is proposed. Content of the Utility Model

[0004] Aiming at the deficiencies of the prior art, the utility model provides a box girder end-anchoring construction device, which solves the problems of great difficulty in disassembling the closing plate due to the large weight of the closing plate and the narrow internal space of the beam box after it is formed, the need for the cooperation of multiple people in the manual disassembly method, and low disassembly efficiency.

[0005] To achieve the above purpose, the utility model provides the following technical solution: A box girder end-anchoring construction device includes a vehicle frame. Support rods are installed at the four corners of the surface of the vehicle frame. A placement table is installed at the top of the support rods. A robotic arm is installed on one side of the placement table. A grasping assembly is arranged at one end of the robotic arm. The grasping assembly includes an adapter pipe installed at the end of the robotic arm. A suction cup is installed at one end of the adapter pipe. A sealing ring is arranged inside the suction cup. A vacuum pump is installed on one side of the robotic arm;

[0006] The robotic arm grasps and moves the closing plate through the grasping assembly, so that the closing plate is removed from the surface of the beam box, and the robotic arm transfers the closing plate to the surface of the placement table, and the placement table restricts the closing plate.

[0007] Preferably, a positioning frame is installed on one side of the robotic arm. The positioning frame is sleeved outside the vacuum pump. The output end of the vacuum pump is connected to the suction cup through a ventilation pipeline.

[0008] Preferably, clamping components are installed at the four corners of the surface of the placement table, and the clamping components cooperate with the placement table to form a placement restriction area for the sealing plate.

[0009] Preferably, the clamping components include baffles installed at the four corners of the surface of the placement table. Threaded grooves are formed on one side of the baffles, and limit rods penetrate through the threaded grooves internally. One end of the limit rod is rotatably connected to a clamping plate.

[0010] Preferably, rotating bases are installed at the four corners of the bottom of the vehicle frame, and universal wheels are installed at the bottoms of the rotating bases.

[0011] Preferably, a number of connecting rods for improving stability are installed between the vehicle frames, and reinforcing ribs for improving the strength of the connecting rods are provided inside the connecting rods.

[0012] Preferably, a lateral extension plate is installed on one side of the vehicle frame, and a control box is installed on the surface of the lateral extension plate. The control box is electrically connected to the robotic arm.

[0013] Compared with the prior art, the utility model provides a box girder sealing and anchoring construction device, which has the following beneficial effects:

[0014] In the technical solution disclosed by the utility model, by using the adjustment of the robotic arm to grab and move the plate, when removing the sealing plate, the grabbing component can directly take down the sealing plate from the end of the box girder and directly place it on the placement table for collection. A single person can complete the removal of the sealing plate without cooperating with other staff, without being restricted by the space of the beam box, improving the disassembly efficiency, and can conveniently transfer the sealing plate along with the vehicle frame, saving the loading and unloading steps.

[0015] In the technical solution disclosed by the utility model, through the provided grabbing component and clamping component, during the process of disassembling the sealing plate, the personnel control the robotic arm, and the robotic arm will drive the suction cup at one end of the connecting pipe to move. After the suction cup contacts the surface of the sealing plate, the sealing ring inside the suction cup will seal the connection between the sealing plate and the suction cup. The vacuum pump can make the inside of the suction cup form a vacuum, and the suction cup will adsorb the sealing plate. After grabbing and moving the sealing plate and placing it on the placement table, then the personnel will rotate the limit rod through the baffle. When the limit rod rotates, it will drive the clamping plate to move towards the middle. When the clamping plate moves towards the middle, it can clamp and fix the sealing plate, playing a role in facilitating the personnel to disassemble and clamp the sealing plate.

The present utility model uses the adjustment of the robotic arm 4 to grasp and move the plate. When removing the sealing plate, the grasping assembly 5 can directly remove the sealing plate from the end of the box girder and directly place it on the placement table 3 for collection, saving the number of operators in the operation room, improving the disassembly efficiency, and facilitating the transfer of the sealing plate along with the vehicle frame 1, saving the loading and unloading steps and reducing the loading and unloading difficulty, realizing a high-efficiency construction mode.

After the suction cup 52 contacts the surface of the sealing plate, the sealing ring 53 inside the suction cup 52 will seal the connection between the sealing plate and the suction cup 52. The vacuum pump 54 can create a vacuum inside the suction cup 52, and the suction cup 52 will adsorb the sealing plate. After grasping and moving the sealing plate, it is placed on the placement table 3. Then, the operator will rotate the limiting rod 62 through the baffle 61.
