Abstract
Description
Technical Field
[0001] This utility model belongs to the field of building construction technology, and specifically relates to a rapid hoisting tool for concrete pipes. Background Technology
[0002] In the traditional process of concrete pipe hoisting, cranes are mostly used in conjunction with manual labor and hoisting slings. Multiple operators are required to tie the hoisting slings, which is slow and costly. Moreover, due to the characteristics of hoisting slings, hoisting instability is prone to occur, resulting in hoisting accidents. After hoisting, pipe connection is usually done by using an excavator or a hand-operated hoist to apply axial force to ensure that the pipe socket is qualified, which is slow in construction efficiency. Utility Model Content
[0003] This utility model addresses the problems of low construction efficiency and safety hazards of existing hoisting tools by providing a rapid hoisting tool for concrete pipes.
[0004] To achieve the above objectives, the present invention adopts the following technical solution:
[0005] A rapid concrete pipe hoisting tool includes a hydraulic cylinder. Three hydraulic supports are evenly distributed circumferentially on the cylinder's housing. One end of each hydraulic support is fixedly mounted on the cylinder's housing, and the other ends of all three supports are jointly fixedly mounted on a main shaft. A coupling is provided between two of the hydraulic supports and connected to a robotic arm. A bushing is provided at the output end of the hydraulic cylinder and is slidably connected to the main shaft. Two collars are fixedly mounted on the main shaft, and three sets of pipe support components are connected to the collars via pins. The three sets of pipe support components are evenly distributed circumferentially around the main shaft.
[0006] Furthermore, the pipe support component includes a clamp, on which one end of a first connecting rod, one end of a second connecting rod, and one end of a third connecting rod are respectively hinged. The other end of the first connecting rod and the other end of the second connecting rod are respectively hinged to a collar, and the other end of the third connecting rod is hinged to a bushing. The first connecting rod and the second connecting rod are arranged in parallel on the same plane, and the second connecting rod and the third connecting rod are arranged in a figure-eight pattern on the same plane.
[0007] Furthermore, a limit block is provided at one end of the gripper near the hydraulic cylinder, and a groove is provided inside the gripper near the main shaft. One end of the first connecting rod, the second connecting rod, and the third connecting rod are all hinged to the groove.
[0008] Furthermore, the gripper is fixedly equipped with anti-slip strips on its exterior away from the main shaft to prevent the gripper from slipping on the concrete pipe during hoisting.
[0009] Compared with the prior art, the present invention has the following advantages:
[0010] 1. This utility model uses a combination of hydraulic cylinder and gripper to lift concrete pipes. By using gripper instead of slings, the amount of machinery used during lifting is reduced, the number of operators is reduced, and the concrete pipes are prevented from falling during handling. This not only ensures the speed of lifting and handling but also improves safety and work efficiency.
[0011] 2. The grippers of this utility model can be adjusted according to concrete pipes of different circumferences, and have a wide range of applications. Attached Figure Description

Detailed Implementation
[0017] To further illustrate the technical solution of this utility model, the following embodiments will be used to further explain this utility model.
[0018] like Figure 1 , Figure 2 and Figure 3As shown, a rapid concrete pipe hoisting tool includes a hydraulic cylinder 1. Three hydraulic supports 2 are evenly distributed circumferentially on the housing of the hydraulic cylinder 1. One end of each hydraulic support 2 is fixedly mounted on the housing of the hydraulic cylinder 1, and the other ends of the three hydraulic supports 2 are jointly fixedly mounted on a main shaft 3. A coupling 4 is provided between two of the hydraulic supports 2, and the coupling 4 is connected to a robotic arm. A bushing 5 is provided at the output end of the hydraulic cylinder 1, and the bushing 5 is slidably connected to the main shaft 3. Two collars 6 are fixedly mounted on the main shaft 3, and three sets of pipe support components 7 are connected to the collars 6 by pins. The three sets of pipe support components 7 are evenly distributed circumferentially around the main shaft 3. Each pipe support component 7 includes a gripper 8, which is close to the hydraulic cylinder 1. A limit block 12 is provided at one end, and a groove 13 is provided inside the gripper near the main shaft 3. One end of the first connecting rod 9, the second connecting rod 10, and the third connecting rod 11 are all hinged to the groove 13. An anti-slip strip 14 is fixedly installed on the outside of the gripper 8 away from the main shaft 3 to prevent the gripper 8 from slipping on the concrete pipe during hoisting. One end of the first connecting rod 9, one end of the second connecting rod 10, and one end of the third connecting rod 11 are respectively hinged to the gripper 8. The other end of the first connecting rod 9 and the other end of the second connecting rod 10 are respectively hinged to a collar 6. The other end of the third connecting rod 11 is hinged to a bushing 5. The first connecting rod 9 and the second connecting rod 10 are arranged parallel to each other on the same plane, and the second connecting rod 10 and the third connecting rod 11 are arranged in a figure-eight pattern on the same plane. Figure 4 As shown, the concrete pipe is hoisted by the cooperation of hydraulic cylinder 1 and gripper 8. The gripper 8 replaces the sling, which reduces the amount of machinery used during hoisting, reduces the number of operators, and prevents the concrete pipe from falling during handling. It improves safety and work efficiency while ensuring hoisting and handling speed.
