Description

Technical Field

[0001] This utility model relates to the field of construction machinery technology, and more specifically, to a device for installing standard section connecting pins. Background Technology

[0002] In the installation process of tower cranes, the connection of standard sections is a crucial step. Traditional standard section connections usually rely on manual operation to insert connecting pins into the corresponding connecting holes. This method has many drawbacks. On the one hand, manual installation is labor-intensive and inefficient, especially when installing high-rise tower cranes, where the difficulty and danger increase with the height. On the other hand, manual installation makes it difficult to ensure the accuracy and consistency of the connecting pin installation, which may lead to an unstable connection of standard sections, affecting the overall stability and safety of the tower crane.

[0019] As attached Figure 1 To be continued Figure 2 An embodiment of this utility model provides a device for installing a standard section connecting pin, including...

[0020] Pull plate 1;

[0021] Support plate 2 is arranged opposite to pull plate 1 on the left and right sides. The side of support plate 2 is provided with fixing bolt 3. Support plate 2 is connected to pull plate 1 by fixing bolt 3.

[0022] A fixed pressure block 4 is provided with a fixing bolt 5 on one side. The fixed pressure block 4 is fixedly installed on the surface of the pull plate 1 by the fixing bolt 5. A hydraulic cylinder body 6 is fixedly installed on the side of the fixed pressure block 4 opposite to the pull plate 1. The piston rod of the hydraulic cylinder body 6 is fixedly connected to a push rod 7. A clamping end 8 is provided at one end of the push rod 7 opposite to the hydraulic cylinder body 6. The drive mechanism adopts a combination of an electric hydraulic pump and a hydraulic cylinder body 6. The electric hydraulic pump provides a power source for the entire drive system and is connected to the hydraulic cylinder body 6 through a hydraulic pipeline. The piston rod of the hydraulic cylinder body 6 is connected to the push rod 7. By controlling the operation of the electric hydraulic pump, the extension and retraction stroke of the hydraulic cylinder piston rod can be precisely adjusted, thereby providing stable and adjustable power for pushing the connecting pin 13.

[0023] The push rod 7 is made of high-strength alloy material, which has good straightness and wear resistance.

[0024] It also includes a through groove 9, which is formed on the surfaces of the pull plate 1 on both sides.

[0025] It also includes a laser rangefinder 10, which is located on the top of the pull plate 1.

[0026] The device also includes an electric push rod 11, a clamping plate 12, and a connecting pin 13. The electric push rod 11 is positioned opposite each other on the left and right sides of the clamping end 8. The clamping plate 12 is fixedly installed on the extension end of the electric push rod 11. The connecting pin 13 is clamped and fixed inside the clamping end 8 by the clamping plate 12. The inner side of the clamping plate 12 is provided with a rubber pad, which can not only firmly clamp the connecting pin 13 and prevent it from slipping during the pushing process, but also avoid damage to the surface of the connecting pin 13.

[0027] It also includes an angle sensor 14, which is located on the top of the clamping end 8.

[0028] The positioning mechanism includes a laser rangefinder 10 and an angle sensor 14. The laser rangefinder 10 is mounted on the pull plate 1 and is used to measure the distance between the device and the connecting hole of the standard section. It controls the drive mechanism through feedback signals so that the connecting pin 13 can be accurately aligned with the connecting hole. The angle sensor 14 is used to detect the pushing angle of the connecting pin 13 to ensure that the connecting pin 13 is inserted into the connecting hole at the correct angle, so as to avoid the connecting pin 13 failing to be inserted smoothly or damaging the connecting hole due to angle deviation. The positioning mechanism is connected to the control system of the device to realize precise positioning control of the installation process of the connecting pin 13.

[0029] The working process of this utility model is as follows: The device is installed above the part of the standard section to be connected, the positioning mechanism of the device is aligned with the connection hole of the standard section, the electric hydraulic pump of the drive mechanism is started, the piston rod of the hydraulic cylinder body 6 extends a certain length, and the push rod 7 of the push mechanism and the clamping device are lowered to the appropriate position. Then, the electric push rod 11 retracts, driving the clamping plate 12 to move horizontally, so that the connecting pin 13 is placed between the two clamping plates 12. The clamping plates 12 close and clamp the connecting pin 13. The laser range sensor 10 of the positioning mechanism measures the distance between the device and the connecting hole of the standard section and transmits the signal to the control system. The control system controls the electric hydraulic pump according to the distance signal and adjusts the extension and retraction of the piston rod of the hydraulic cylinder body 6 so that the connecting pin 13 is accurately aligned with the connecting hole. At the same time, the angle sensor 14 detects the angle of the connecting pin 13. If there is a deviation in the angle, the control system corrects it by adjusting the working parameters of the drive mechanism. When the connecting pin 13 is aligned with the connecting hole and the angle is correct, the drive mechanism continues to work. The piston rod of the hydraulic cylinder body 6 pushes the push rod 7, so that the connecting pin 13 is slowly inserted into the connecting hole along the guide groove of the standard section until the connecting pin 13 is fully inserted into place, completing the automatic installation of the standard section and the connecting pin 13.
