Description

Technical Field

[0001] The invention relates to the technical field of building construction, in particular to pipe hole sand and gravel clearing equipment and a cleaning method for prefabricated pipe piles. Background Art

[0002] Precast pipe piles are hollow cylindrical slender concrete precast components made by prestressing technology and centrifugal forming methods. They are mainly composed of a cylindrical pile body, an end plate and a steel sleeve. When the precast pipe piles are sunk into the soil, the pile head will be clogged with mud and gravel. When the pipe piles are used, concrete needs to be poured inside them. In order to ensure a stable connection between the concrete and the inner wall of the pipe piles, it is usually necessary to clean the mud and gravel inside the pipe piles before pouring the concrete.

[0003] Chinese patent CN219690515U discloses an efficient equipment for cleaning pile holes. By setting a moving component and a rotating component, the auger rod can sweep out the sand, gravel and soil in the pile hole. However, when the auger is used to clean the pile hole, in order to ensure the working efficiency of the auger, the diameter of the auger needs to be several centimeters smaller than the diameter of the pile hole. That is to say, the auger will not continuously contact the inner wall of the pile hole when working, so that a lot of soil and gravel will be left on the inner wall of the pile hole. At the same time, the exposed auger also has certain safety hazards.

[0004] Chinese patent CN113309104B discloses a prefabricated pipe pile core soil cleaning device, in which a conveying cylinder is arranged outside the auger, so that the auger is not directly exposed to the outside world, reducing safety hazards. At the same time, an interlayer is arranged between the inner and outer layers of the conveying cylinder as a water conveying channel, and water is conveyed to the inside of the pipe pile through the water conveying channel to moisten the pile core soil, thereby reducing the difficulty of crushing and conveying by the auger; however, this device cannot clean the mud and sand that are sticky on the inner wall of the pipe pile hole, but only improves the safety of the equipment operation and reduces the difficulty of work, and cannot actually improve the cleaning effect of the inner wall of the pipe pile hole.

[0005] Furthermore, the above two devices can only perform pipe hole clearing operations on prefabricated pipe piles with fixed pipe hole diameters, and cannot effectively clean pipe piles with different pipe diameters, and thus have a narrow scope of application. Summary of the invention

The distance adjustment component 81 is used to adjust the distance between the axis of the auger 4 and the center of the circular hole 21, and the surrounding component 82 is used to control the translation mounting plate 3 to rotate around the center of the circular hole 21.

[0053] As can be seen from the above, by arranging the protective sleeve 5 on the outside of the auger 4, the sand and gravel in the pipe hole of the prefabricated pipe pile can be transported upward from the inside of the protective sleeve 5, avoiding the auger 4 from being directly exposed to the outside world, reducing safety hazards, and cooperating with the arrangement of the scraper plate 6 and the scraper mechanism 7, when the telescopic cylinder 72 contracts, the scraper opening component 74 controls the scraper plate 6 installed on the outer wall of the protective sleeve 5 to rotate and open, and the sleeve rotating component 73 makes the protective sleeve 5 rotate synchronously with the auger 4, so as to scrape off the sand and gravel soil adhering to the inner wall of the pipe hole of the prefabricated pipe pile. At the same time, by arranging the horizontal displacement control mechanism 8, the protective sleeve 5 can be controlled to move to different positions on the inner wall of the prefabricated pipe pile The protective sleeve 5 is arranged to be cleaned, and by setting a surrounding component 82, when the protective sleeve 5 and the auger 4 rotate synchronously, the surrounding component 82 can drive the protective sleeve 5 to rotate around the axis of the prefabricated pipe pile, so that the scraper plate 6 can clean different positions of the inner wall of the prefabricated pipe pile, and by setting a distance adjustment component 81, the position of the protective sleeve 5 inside the prefabricated pipe pile can be adjusted, so that the scraper plate 6 can contact the inner wall of the prefabricated pipe pile with different inner diameters when it is unfolded; in the present application, a crushing cone is arranged at the lower end of the auger 4, which can crush the agglomerated soil so that the protective sleeve 5 can be inserted into the crushed sand and gravel on the ground when it contacts the sand and gravel and limit it inside, so that the auger 4 can transport the sand and gravel upward.

[0054] When using the obstacle removal equipment, the mobile bracket 1 is moved to the top of the prefabricated pipe pile after the piling is completed, so that the center of the circular hole 21 coincides with the axis of the prefabricated pipe pile hole; the driving motor 31 is started to control the rotation of the auger 4, and the lifting mounting plate 2 is controlled to move downward to discharge the sand, gravel and soil inside the prefabricated pipe pile from the soil discharge port 51; after the sand and gravel in the prefabricated pipe pile hole are cleaned to a specified depth, the driving end of the telescopic cylinder 72 is controlled to retract, and the protective sleeve 5 is moved through the distance adjustment component 81, so that the scraper plate 6 can scrape off the sand and gravel stuck on the inner wall of the prefabricated pipe pile hole; the surrounding component 82 is started to rotate the protective sleeve 5 around the inner wall of the prefabricated pipe pile hole; after the sand and gravel stuck on the inner wall of the prefabricated pipe pile hole are scraped off, the driving end of the telescopic cylinder 72 is controlled to extend, and the sand and gravel that falls to the bottom of the prefabricated pipe pile hole is taken out by the auger 4.

[0055] Embodiment 2

[0056] like Figure 3 , Figure 4 , Figure 5 and Figure 6As shown, the difference between this embodiment and the above embodiment is that the sleeve rotating component 73 includes an upper toothed disc 731 and a lower toothed disc 732, the upper toothed disc 731 is fixedly mounted on the shaft of the auger 4, and the lower toothed disc 732 is fixedly mounted on the upper surface of the fixed plate 71, and the opposite ends of the upper toothed disc 731 and the lower toothed disc 732 are adapted to be snap-fitted.

[0057] The scraper opening component 74 includes a transmission gear 741, a tooth plate 742, a sliding plate 743 and a rotating plate 744. A scraper shaft 61 is fixedly installed at one end of the scraper plate 6. The scraper shaft 61 is rotatably installed on the outer side of the protective sleeve 5, and the upper end of the scraper shaft 61 passes through the lower surface of the fixed plate 71 and extends above it. The transmission gear 741 is fixedly installed on the upper end of the scraper shaft 61, and a guide rail 711 is fixedly installed on the upper surface of the fixed plate 71. The tooth plate 742 is slidably installed inside the guide rail 711, and the tooth surface of the tooth plate 742 is adapted to mesh with the transmission gear 741. The sliding plate 743 slides in a circle on the lower surface of the translation mounting plate 3 with the axis of the auger 4 as the center of the circle, and the two ends of the rotating plate 744 are slidably connected with the tooth plate 742 and the sliding plate 743 respectively.

[0058] The wall scraping mechanism 7 also includes an annular track 75 and an annular slider 76. The annular track 75 is fixedly mounted on the lower surface of the translation mounting plate 3, and the annular track 75 is slidably connected to the annular slider 76. The driving end of the telescopic cylinder 72 and the sliding plate 743 are both fixedly mounted on the lower surface of the annular slider 76.

[0059] As can be seen from the above, due to the setting of the annular track 75 and the annular slider 76, the driving end of the telescopic cylinder 72 and the sliding plate 743 can rotate with the fixed plate 71 relative to the translation mounting plate 3; when the telescopic cylinder 72 contracts, the lower toothed disc 732 approaches the upper toothed disc 731, the upper toothed disc 731 and the lower toothed disc 732 are snap-connected, the auger 4 and the protective sleeve 5 are relatively fixed, and the protective sleeve 5 can be driven to rotate by the auger 4; when the telescopic cylinder 72 contracts, the fixed plate 71 approaches the translation mounting plate 3, and the sliding plate 743 pushes the rotating plate 744 to increase the inclination angle, driving the toothed plate 742 to slide, thereby pushing the transmission gear 741 to rotate, so that the scraper plate 6 rotates and opens.

[0060] Embodiment 3

[0061] like Figure 7 and Figure 8As shown, the difference between this embodiment and the above embodiment is that the distance adjustment component 81 includes a limit frame 811, a guide rod 812 and a screw 813, the limit frame 811 is installed on the upper surface of the lifting mounting plate 2, the guide rod 812 is fixedly installed between the inner walls on both sides of the limit frame 811, the screw 813 is rotatably installed between the inner walls on both sides of the limit frame 811, and one end of the screw 813 passes through the inner wall of one side of the limit frame 811 and extends to the outside of the limit frame 811 and is fixedly installed with a knob 814, and the guide slider 32 and the threaded slider 33 are fixedly installed on both sides of the upper surface of the translation mounting plate 3, respectively, the guide slider 32 is slidably connected to the guide rod 812, and the threaded slider 33 is threadedly connected to the screw 813.

[0062] The surrounding component 82 includes an annular slide 821 and an arc-shaped slider 822. The annular slide 821 is fixedly mounted on the upper surface of the lifting mounting plate 2, and the arc-shaped slider 822 is fixedly mounted on the lower surface of the limit frame 811. The arc-shaped slider 822 is slidably mounted inside the annular slide 821. The annular slide 821 is coaxially arranged with the circular hole 21.

[0063] The surrounding component 82 also includes a control motor 823, a driving gear 824 and inner teeth 825. The control motor 823 is rotatably mounted on one side of the upper surface of the translation mounting plate 3, the driving gear 824 is fixedly mounted on the driving end of the control motor 823, and the inner teeth 825 are fixedly mounted on the inner side of the circular hole 21, and the inner teeth 825 are meshedly connected with the driving gear 824.

[0064] As can be seen from the above, when the screw rod 813 is rotated, the translation mounting plate 3 can move along the length direction of the guide rod 812. Since the prefabricated pipe pile mentioned in the present application is a cylindrical concrete hollow pipe, when the center of the circular hole 21 coincides with the axis of the prefabricated pipe pile hole, moving the translation mounting plate 3 in any horizontal direction only changes the distance between the axis of the auger 4 and the axis of the prefabricated pipe pile hole; by setting the surrounding component 82, due to the setting of the annular slideway 821 and the arc-shaped slider 822, the center point of the limit frame 811 always coincides with the vertical axis where the circular hole 21 is located, and the limit frame 811 is driven to rotate with its center point as the axis by the engagement of the inner teeth 825 when the active gear 824 rotates; therefore, when the limit frame 811 rotates, the auger 4 and the protective sleeve 5 revolve around the circular hole 21. At this time, the scraper plate 6 on the outer side of the protective sleeve 5 can be used to scrape off the sand, gravel and soil sticking to the inner wall of the prefabricated pipe pile hole.

[0065] Embodiment 4

[0066] like Figure 8As shown, the difference between this embodiment and the above embodiment is that a lifting control mechanism 9 is provided on the mobile bracket 1, and the lifting control mechanism 9 includes a chain 91, an upper sprocket 92, an upper direction-changing sprocket 93, a driving sprocket 94, a lower direction-changing sprocket 95, a lower sprocket 96 and a rotating rod 97. The upper sprocket 92 and the lower sprocket 96 are rotatably mounted on the upper and lower ends of the mobile bracket 1, respectively, the driving sprocket 94 is rotatably mounted on one side of the mobile bracket 1, and the upper direction-changing sprocket 93 and the lower direction-changing sprocket 95 are respectively arranged on the driving sprocket 94. The upper and lower sides of the sprocket 94, and the upper changing sprocket 93 and the lower changing sprocket 95 are rotatably mounted on one side of the mobile bracket 1, the chain 91 is wound around the upper sprocket 92, the upper changing sprocket 93, the driving sprocket 94, the lower changing sprocket 95 and the lower sprocket 96, and the chain 91 is fixedly connected to a side wall of the lifting mounting plate 2, the rotating rod 97 is rotatably mounted on one side of the mobile bracket 1, and the rotating rod 97 and the driving sprocket 94 are connected by a bevel gear transmission, and a rocker arm 98 is fixedly mounted on the end of the rotating rod 97.

[0067] A guide rod 99 is fixedly mounted on the movable bracket 1 , and the lifting mounting plate 2 is slidably mounted on the guide rod 99 .

[0068] As can be seen from the above, due to the setting of the guide rod 99, the lifting installation plate 2 can only slide up and down in a straight line. Due to the setting of the chain 91, the upper sprocket 92, the upper changing sprocket 93, the driving sprocket 94, the lower changing sprocket 95 and the lower sprocket 96, when the driving sprocket 94 is rotated, the chain 91 can pull the lifting installation plate 2 up and down. Since the rotating rod 97 and the driving sprocket 94 are driven by a bevel gear, the rotating rocker arm 98 can control the rotation of the driving sprocket 94.

[0069] Embodiment 5

[0070] See also Figure 1 - Figure 8 The present invention also discloses a cleaning method for prefabricated pipe piles, which comprises the following specific steps:

[0071] Move the mobile support 1 to the top of the prefabricated pipe pile after piling, so that the center of the circular hole 21 coincides with the axis of the prefabricated pipe pile hole;

[0072] The driving motor 31 is started to control the auger 4 to rotate, and the lifting installation plate 2 is controlled to move downward, so that the sand, gravel and soil inside the prefabricated pipe pile are discharged from the soil discharge port 51;

[0073] After the sand and gravel in the prefabricated pipe pile hole is cleaned to a specified depth, the driving end of the telescopic cylinder 72 is controlled to retract, and the protective sleeve 5 is moved through the distance adjustment component 81, so that the scraper plate 6 can scrape off the sand and gravel stuck on the inner wall of the prefabricated pipe pile hole;

[0074] Start the surrounding component 82 to make the protective sleeve 5 rotate around the inner wall of the prefabricated pipe pile hole;

[0075] After the sand and gravel sticking to the inner wall of the prefabricated pipe pile hole are scraped off, the driving end of the telescopic cylinder 72 is controlled to extend, and the sand and gravel falling to the bottom of the prefabricated pipe pile hole is taken out by the auger 4.

[0076] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
