Description

Technical Field

[0001] This utility model relates to the field of cement mixing pile technology, and in particular to a visual cement mixing pile length positioning device. Background Technology

[0002] In the current engineering construction field, cement mixing piles are widely used as a common method for foundation reinforcement. Traditionally, pile length is determined by marking the outside of the cement mixing rod and using the corresponding length markings on the outside of the tower to determine the pile's depth. This method, under ideal daylight conditions, allows construction workers to accurately judge the pile depth based on clearly visible markings, ensuring the feasibility of routine operations during the foundation stage of cement mixing pile construction. It has long played a vital role in numerous engineering projects, providing a workable solution for foundation treatment.

[0003] However, existing technologies have significant drawbacks. First, in nighttime construction scenarios, insufficient light makes it difficult to accurately determine the marking positions. Construction workers, relying solely on visual observation and on-site lighting, struggle to precisely determine the correspondence between the markings and the scale, significantly increasing the risk of errors in pile length determination and severely impacting construction accuracy and project quality. Second, manually marking outside the tower itself poses substantial safety hazards. Construction workers must reach the corresponding pile height, facing risks such as falls from heights and accidental collisions. Especially in high-altitude operations, complex weather conditions and confined working spaces further exacerbate safety threats, contradicting the stringent safety requirements of modern engineering construction. Therefore, there is an urgent need for a more precise, safer, and environmentally unrestricted technology for determining the pile length of cement mixing piles to replace traditional methods.

[0024] Please refer to Figure 1 The present invention provides a visual cement mixing pile length positioning device, comprising a pile driver, a mixing rod 5, a marking structure, a warning element 23, and a response structure.

[0025] The piling machine forms the foundation of the entire system, providing power for the rotation of the mixing rod 5 and the driving of the piles. The mixing rod 5 is driven to rotate and extend downwards by the piling machine's drive unit.

[0026] Please refer to Figure 1 and Figure 2In this embodiment, the marking structure is movably disposed outside the stirring rod 5. The marking structure includes a movable ring 6, multiple friction wheels 8, a transmission structure, an infrared rangefinder 16, and a drive motor 13.

[0027] The inner side of the movable ring 6 has a groove 7, and a rotating shaft 10 passes through the shaft of multiple friction wheels 8. The rotating shaft 10 is rotatably mounted on the groove 7, so that the multiple friction wheels 8 can rotate on the movable ring 6.

[0028] The outer wall of the stirring rod 5 has multiple guide grooves 9 for cooperating with the friction wheels 8 in the marking structure. Each friction wheel 8 is embedded in the guide groove 9 on the outer wall of the stirring rod 5 and contacts the inner wall of the guide groove 9 through friction, thereby ensuring that the movable ring 6 can move stably along the stirring rod 5 and can be precisely adjusted to its position outside the stirring rod 5.

[0029] An infrared rangefinder 16 is mounted on a bracket 15 outside the movable ring 6 to measure the distance between the movable ring 6 and the pile driver. Another receiver is installed at the top of the pile driver to receive the signal from the infrared rangefinder 16, thereby determining the distance between the movable ring 6 and the top of the pile driver. In this way, construction personnel can obtain the position information of the movable ring 6 in real time from the control room, thus determining the length of the mixing rod 5 for pile driving. This solves the problem of difficulty in determining the marked position at night, improving the visualization and accuracy of the construction process.

[0030] Please refer to Figure 2 In this embodiment, the transmission structure is used to transmit the power of the drive motor 13 to each friction wheel 8 to achieve synchronous rotation. The transmission structure includes multiple drive shafts 12 and multiple universal joints 11. Each drive shaft 12 has a universal joint 11 at both ends, and the universal joint 11 is connected to the rotating shaft 10. The multiple drive shafts 12 are connected to the multiple rotating shafts 10 and arranged in a ring.

[0031] The drive motor 13 is located outside the movable ring 6, and its output end is connected to a transmission shaft 12 via a helical gearbox 14. When the drive motor 13 is working, it changes the direction of power transmission through the helical gearbox 14, causing the transmission shaft 12 to rotate. The rotational motion is then transmitted to each rotating shaft 10 through the universal joint 11, thereby causing the multiple friction wheels 8 to rotate synchronously under the drive of the drive motor 13. This transmission structure ensures that each friction wheel 8 rotates at the same speed and direction, thus guaranteeing the smoothness and accuracy of the movable ring 6's movement outside the stirring rod 5.

[0032] Please refer to Figure 1 In this embodiment, the warning device 23 is used to issue a positioning information when the marking structure moves to the lower end of the pile driver, so as to remind the construction personnel that the pile length has reached the predetermined length.

[0033] Please refer to Figure 3In an optional embodiment, the response structure is disposed outside the active ring 6. After the active ring 6 moves into position, it is used to connect the power supply of the warning element 23, so that the warning element 23 works.

[0034] Furthermore, the response structure includes a conductive ring 22, a strong magnetic block 19, and a power supply 18. The power supply 18 is disposed within the mounting bracket 15, the strong magnetic block 19 is slidably connected relative to the mounting bracket 15, and the strong magnetic block 19 is connected to the power supply 18 via a wire 20.

[0035] The conductive ring 22 is mounted on the protective frame 2 of the pile driver. It is magnetically attracted to the strong magnetic block 19, and the conductive ring 22 is electrically connected to the input end of the warning device 23. When the movable ring 6 moves with the strong magnetic block 19 to the lower position of the pile driver, the strong magnetic block 19 and the conductive ring 22 are magnetically attracted, so that the power supply 18 connects to the warning device 23 through the circuit formed by the wire 20 and the conductive ring 22, thereby triggering the warning device 23 to issue a positioning information.

[0036] To enhance the reliability and conductivity of the connection, the strong magnetic block 19 has multiple raised contacts 21 on one side of the conductive ring 22. These contacts 21 are electrically connected to the wire 20, ensuring the stability of the circuit connection. Simultaneously, the side of the strong magnetic block 19 that contacts the conductive ring 22 is arc-shaped, with the same arc as the inner arc of the conductive ring 22. This allows the strong magnetic block 19 and the conductive ring 22 to fit tightly together, further improving the stability of the magnetic attraction and the conductivity.

[0037] It should be noted that the pile driver includes a base 1, a protective frame 2, a support cage 3, and a pile top 4. The protective frame 2 is equipped with a connection structure for the corresponding warning element 23, which provides a position for the installation and fixing of the warning element 23, ensuring that the warning element 23 can stably send out the positioning information.

[0038] In use, the visual cement mixing pile length positioning device of this utility model drives the friction wheel 8 to rotate via the drive motor 13. Under the frictional force of the friction wheel 8 within the guide groove 9 on the outer wall of the mixing rod 5, the movable ring 6 can move stably along the mixing rod 5. The infrared rangefinder 16 measures the distance between the movable ring 6 and the receiver at the top of the pile driver in real time. Construction personnel can intuitively adjust the position of the mark outside the mixing rod 5 from the control room, eliminating the need for manual marking outside the tower and thus eliminating the safety hazards associated with manual marking. When the movable ring 6 moves to the lower end of the pile driver, the strong magnetic block 19 and the conductive ring 22 magnetically engage, activating the warning element 23. The warning element 23 sends out a positioning information, promptly reminding the construction personnel that the pile length has reached the predetermined length. This eliminates the need to judge blurry marks at night, greatly improving construction accuracy and efficiency.

It should be understood that these are relative concepts and can vary depending on different methods of use and placement; the use of these directional terms should not limit the scope of protection claimed in this application.
