Description

Technical Field

[0001] The utility model belongs to the technical field of spiral pile drivers, in particular to a spiral pile driver cleaning device used in construction sites. Background Art

[0002] A spiral pile driver is a device that uses a power mechanism to drive a long drill rod to spirally descend and drill holes. In order to reduce the coaxiality of the drill rod and the verticality of the drill hole during the spiral descent, a vertical casing needs to be installed at the bottom of the drill rod surface to ensure the vertical descent of the drill rod.

[0003] However, the existing vertical casing is fixedly connected to the bottom of the drill rod, which is not convenient to disassemble and assemble, and has poor flexibility. Moreover, after the drill rod is lifted from the borehole, the soil on the drill rod needs to be shaken off. However, when working in areas with high soil viscosity, the soil adhering to the spiral rod will affect the normal operation when the drill rod is drilled again. Utility Model Content

DETAILED DESCRIPTION

[0022] In order to better understand the purpose, structure and function of the present invention, the following is a further detailed description of a spiral pile driver cleaning device for a construction site of the present invention in conjunction with the accompanying drawings.

[0023] like Figure 1 and Figure 2 As shown, a spiral pile driver cleaning device for construction sites includes a frame body 1, a first rotating member 2, a guide plate 3, a support frame 4, a hanging member 5, a driving assembly 6, an auger rod 7 and a first hydraulic rod assembly 8, wherein the front end of the frame body 1 is swingably connected to the guide plate 3 through the first rotating member 2, guide grooves 31 are opened on both sides of the guide plate 3, and guide blocks 32 are provided in the guide grooves 31, the inner side of the support frame 4 is connected to the guide blocks 32, and is slidably connected to the guide plate 3 through the guide blocks 32, the upper end surface of the support frame 4 is connected to the hanging member 5, the driving assembly 6 is installed inside the support frame 4, the auger rod 7 is connected to the driving assembly 6, and is driven to rotate by the driving assembly 6, the rear side of the guide plate 3 is connected to the first hydraulic rod assembly 8, and the lower end of the first hydraulic rod assembly 8 is connected to the frame body 1.

[0024] The drive assembly 6 includes a drive motor 61 and a gearbox 62. The drive motor 61 is mounted on the support frame 4. The gearbox 62 is connected to the output of the drive motor 61, which in turn is connected to the auger rod 7. The gearbox 62 adjusts the speed of the drive motor 61 to ensure an appropriate speed. Two first hydraulic rod assemblies 8 are provided in parallel. These two hydraulic rods ensure greater stability and reliability during the flipping process of the guide plate 3.

[0025] like Figure 3 and Figure 4As shown, a support plate assembly 9 is provided on the front side of the guide plate 3, and the support plate assembly 9 includes a support portion 91 and a guide portion 92 integrally formed with the support portion 91, and the guide portion 92 is slidably connected to the guide groove 31, and a fastening bolt 93 is connected to the middle of the guide portion 92. The two sides of the support portion 91 are connected to the limiting plate 10 through a rotating shaft, and a limiting hole 101 is provided in the middle of the limiting plate 10. A first fixed shaft 102 is provided on the inner side of the upper end surface of the limiting plate 10, and a magnetic block 103 is provided on the upper end of the first fixed shaft 102. A cleaning assembly 11 is provided on the outer periphery of the first fixed shaft 102, and the cleaning assembly 11 and the magnetic block 103 are connected by a torsion spring 104.

[0026] The frame body 1 can be mounted on a vehicle. During transport, the first hydraulic rod assembly 8 is retracted to flatten the guide plate 3 onto the upper end of the frame body 1, facilitating transport of the entire device. After the device is transported to the work site via the vehicle, the first hydraulic rod assembly 8 is used to push the guide plate 3 to a vertical position. The drive assembly 6 then rotates the auger rod 7, and the support frame 4 is conveyed downward via the sling 5, allowing the auger rod 7 to pass vertically downward through the stop hole 101. The opening size of the stop hole 101 is adapted to the auger rod 7, ensuring that the auger rod 7 does not deflect during its downward penetration into the soil. When the stop plate 10 is no longer needed, it can be flipped around the axis of rotation toward the guide plate 3 and attached to the front side of the guide plate 3 via the magnetic block 103, providing greater flexibility. Furthermore, the position of the stop plate 10 within the guide slot 31 can be adjusted by the guide portion 92, and the position of the stop plate 10 is defined by the tightening bolt 93, further enhancing the flexibility of the position of the stop plate 10.

[0027] like Figure 5 As shown, the cleaning assembly 11 includes a swing plate 111 having an arcuate groove 112 formed on the side wall of the swing plate 111 facing the auger rod 7. A cleaning portion 113 is provided on one side of the arcuate groove 112, and a tilting block 114 is provided on the lower side of the cleaning portion 113. In the initial state, the arcuate groove 112 is engaged with the shaft in the middle of the auger rod 7 by the action of the torsion spring 104, while the cleaning portion 113 presses against the spiral blades of the auger rod 7. As the auger rod 7 rotates and drills downward into the soil, the clay on the spiral blades is scraped off by the cleaning portion 113. The scraped soil is then pushed outward along the upper end surface of the cleaning portion 113 and through the soil. When the auger rod 7 is completely rotated into the soil, the auger rod 7 is lifted up, and the spiral blades on the auger rod 7 are used to lift the crushed soil. The soil will hit the inclined block 114 upward, and then drive the limit plate 10 to swing away from the auger rod 7, thereby ensuring that the limit plate 10 and the cleaning part 113 will not interfere with the lifting process of the auger rod 7.

[0028] A second fixed shaft 12 is provided on the upper side of the cleaning section 113. A cleaning disc 13 is rotatably connected to the outer periphery of the second fixed shaft 12. Multiple scrapers 14 are evenly distributed around the outer periphery of the cleaning disc 13. The scraped dirt slides outward along the upper end surface of the cleaning section 113, and clay easily adheres to the upper end surfaces of the scrapers 14. Consequently, due to the arrangement of the scrapers 14, the cleaned dirt will squeeze one of the scrapers 14, pushing it to swing. Consequently, the adjacent scraper 14 will move in the direction of the scraper 14 pushed by the dirt, thus cleaning the upper end surface of the cleaning section 113. If the upper end surface of the cleaning section 113 is too dirty and difficult to clean, the scrapers 14 can be manually rotated to remove the dirt adhering to the upper end surface of the cleaning section 113. Alternatively, the scrapers 14 can be driven by a motor to rotate to perform the cleaning work.

[0029] like Figure 6 and Figure 7 As shown, the lower end surface of the guide plate 3 is provided with a second hydraulic rod assembly 15, and the lower end of the second hydraulic rod assembly 15 is provided with a pressure plate 16. After the guide plate 3 is pushed to a vertical position by the first hydraulic assembly 8, the second hydraulic rod assembly 15 then pushes the pressure plate 16 against the ground, thereby supporting the guide plate 3. This can reduce the pressure on the first hydraulic rod assembly 8 and the first rotating member 2, ensuring the stability of the support for the guide plate 3.
