Description

Technical Field

[0001] The utility model relates to a verticality detection device for a cement-soil mixing pile, belonging to the field of construction. Background Art

[0002] Cement mixing piles are categorized by their primary construction method into single-shaft, double-shaft, and triple-shaft types. These piles are suitable for treating silt, muddy soil, plain fill, soft-plastic clay, loose-medium-dense silty sand, slightly dense-medium-dense silt, loose-slightly dense medium-coarse sand and gravel, and loess. They consolidate soft soils to improve foundation bearing capacity. There are various types of pile mixers, including screw and crawler types.

[0003] The verticality detection device used in the existing cement mixing pile detects the verticality of the pile body by connecting the output ends of the first laser rangefinder and the second laser rangefinder to the display device respectively. However, when the drill rod and the drill bit are inserted into the ground, unexpected situations may occur, causing the drill rod and the drill bit to be not vertical. The staff cannot discover it in time, which affects the quality of subsequent work. In addition, when the drill rod and the drill bit are inserted into the ground, the depth of the drill rod and the drill bit in the ground is unknown, which brings inconvenience to the staff.

[0025] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0026] See also Figure 1 The utility model provides a technical solution: a cement soil mixing pile verticality detection device, comprising a cement soil mixing pile body 1 and a drill rod 2, the outer surface of the drill rod 2 may be provided with scale lines, the outer wall of the cement soil mixing pile body 1 is provided with a pointer plate 3 corresponding to the scale lines, the bottom end of the drill rod 2 is provided with a drill tip, the inner bottom of the drill rod 2 is provided with an inclination sensor 4, the cement soil mixing pile body 1 is provided with a horizontal bracket 5, the four corner ends of the horizontal bracket 5 are connected to the tilt component through a height adjustment component, and a laser rangefinder 1 6 and a laser rangefinder 2 7 are installed on the horizontal bracket 5.

[0027] See Figure 1-2The height adjustment assembly is four in total, and the height adjustment assembly includes a rotating rod 8 that passes through the four corners of the horizontal bracket 5. A manual turntable 9 is fixed to the top of the rotating rod 8. The outer surface of the rotating rod 8 is engraved with an external thread, and the outer surface of the bottom of the rotating rod 8 is threaded with an internal threaded tube 10. The internal threaded tube 10 is fixed to the middle of the top of the connecting plate 11. A telescopic rod 12 is fixed to the outer surface of the rotating rod 8 with a bearing 13. The bearing 13 is fixed to the bottom end of the horizontal bracket 5. Manually rotating the manual turntable 9 drives the rotating rod 8 to rotate, and the threaded sleeve at the bottom of the rotating rod 8 is sleeved in the internal threaded tube 10. The rotating rod 8 rotates in place, and finally drives the internal threaded tube 10 to move up and down on the rotating rod 8, thereby driving the height adjustment of the tilt assembly. During the adjustment, the designed telescopic rod 12 ensures the lifting stability, and the telescopic length of the telescopic rod is limited to ensure that the threaded sleeve of the internal threaded tube 10 and the rotating rod 8 will not be separated.

[0028] See Figure 1-6, the total number of the tilting components is four, and the tilting components include a U-shaped frame 14 and a tilting plate 15 fixed to the bottom end of the connecting plate 11. An arc-shaped slide 16 is provided on both sides of the U-shaped frame 14. Both sides of the bottom end of the tilting plate 15 are fixed with an arc block 17 sliding in the arc slide 16. The inner wall of the arc slide 16 near the inner end is fixed with an arc-shaped limit block 18. A limit space 19 is formed between the arc limit block 18 and the arc slide 16. The arc block 17 is fixed with an arc-shaped slider 20 that is slidably limited in the limit space 19. The tilting group also includes an arc plate 21 fixed to the bottom end of the tilting plate 15. A driving assembly for driving the arc plate 21 is provided in the U-shaped frame 14. A worm is arranged on the bottom end surface of the arc plate 21. The driving assembly includes a transmission rod 23. A transmission sleeve 24 is fixed on the outer surface of the transmission rod 23. The transmission sleeve 24 is a worm. The transmission sleeve 24 is engaged with the worm. The appearance of the transmission rod 23 A gear 25 is fixed on the surface, and a secondary transmission rod 26 is provided below the transmission rod 23. The outer surface of the secondary transmission rod 26 is sleeved with a secondary gear 27 that meshes with the gear 25. A fixing plate 28 is fixed to one end of the U-shaped frame 14. One end of the secondary transmission rod 26 passes through the fixing plate 28 and is fixed with a secondary manual turntable that contacts the outer side surface of the fixing plate 28. The outer surface of the secondary transmission rod 26 is engraved with a secondary external thread. A threaded block 29 is threaded on the secondary transmission rod 26. The other end of the secondary transmission rod 26 is sleeved with a bearing 2 30, which is fixed on a bearing plate 31. The bearing plate 31 is fixed to the inside of the U-shaped frame 14. One end of the transmission rod 23 is sleeved with a bearing 32 fixed on the bearing plate 31. The other end of the transmission rod 23 and the secondary transmission rod 26 are both sleeved with a bearing 4 33. The bearing 4 33 is fixed on the inner side surface of the fixing plate 28, and a traction rod 34 that slides through the threaded block 29 is fixed on the bearing plate 31.

[0029] Manually rotate the secondary manual turntable to drive the secondary transmission rod 26 to rotate, and the secondary transmission rod 26 drives the secondary gear 27, gear 25, transmission rod 23, and transmission sleeve 24 to rotate together. The transmission sleeve 24 transmits the worm gear connected to the bottom of the arc plate 21, and finally drives the arc plate 21 to perform arc motion, thereby driving the top inclined plate 15 to perform arc motion together. The designed arc block 17 slides synchronously in the arc groove 16, and the arc slider 20 on the arc block 17 slides synchronously in the limit space 19 formed between the arc limit block 18 and the arc groove 16 to ensure that the arc block 17 will not disengage when sliding in the arc groove 16. Finally, the manual forward and reverse rotation of the secondary transmission rod 26 drives the inclined plate 15 to tilt to the upper right or upper left to complete the tilt adjustment.

[0030] When the secondary transmission rod 26 rotates, the threaded block 29 will be driven to move left and right on the secondary transmission rod 26. When the secondary transmission rod 26 is not rotated, the threaded block 29 will stay on the secondary transmission rod 26. At this time, when the secondary transmission rod 26 is not manually turned, the design of the threaded block 29 ensures that the secondary transmission rod 26 will not rotate on its own, thereby ensuring that the tilt plate 15 is fixed after adjustment. Figure 3 and Figure 6 The U-shaped frame 14, the curved plate 21 and the components designed thereon are drawn upwards. In fact, the U-shaped frame 14, the curved plate 21 and the components designed thereon are all designed in an inverted direction. Figure 1 It is correct that the middle U-shaped frame 14 faces downward. The reason why the upward U-shaped frame 14, the curved plate 21 and the components designed thereon are drawn is to make it easier to see the components. All the bearings are designed to ensure that the corresponding components rotate more stably.

[0031] During specific work, when the drill rod 2 drives the drill bit to drill into the ground, the verticality of the drill rod 2 and the drill bit drilled into the ground can be detected by the inclination sensor 4. If the drill rod 2 and the drill bit have special circumstances and the angle is tilted when drilling into the ground, the user can check it in time through the display device. The inclination sensor 4 is also connected to the display device. After the drill rod 2 and the drill bit are drilled into the ground, when the scale line set on the outside of the drill rod 2 stays at the position of the pointer plate 3, it is the depth of insertion into the ground, which is convenient for the staff to check at any time, brings convenience to the staff, and prevents the tilt from not meeting the construction requirements. The inclination sensor 4 needs to be connected to the display device. The display device is an existing structure in this field. Without going into too much detail, the display device allows the staff to check in time. When the inclination angle of the drill rod 2 exceeds a certain limit, the staff can adjust the inclination angle of the drill rod 2 by adjusting the height of the cement soil mixing pile body 1 at the end of the drill rod 2 through the height adjustment component, and then adjusting the angle of the cement soil mixing pile body 1 with the tilting component. Since the geographical location of each region is different and the levelness of the ground is different, if the ground is uneven, the overall device is difficult to operate and is prone to errors. At this time, the user can adjust the tilting components and height adjustment components at different positions according to the geographical environment to solve the problem of different ground levels.

[0032] Although this specification is described according to implementation methods, not every implementation method contains only one independent technical solution. This narrative method of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment can also be appropriately combined to form other implementation methods that can be understood by those skilled in the art.
