DETAILED DESCRIPTION

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

[0026] See also Figures 1 to 3 , the utility model provides a technical solution:

[0027] A small-diameter quick pile extraction device comprises a lifting platform 1, a motor frame 2 is fixedly installed on the top of the lifting platform 1, a motor 3 is fixedly installed on the top right side of the motor frame 2, a rotating rod 4 is fixedly installed on the output end of the motor 3 through the motor frame 2, a transmission gear 5 is fixedly installed on the bottom of the rotating rod 4, three groups of supporting telescopic rods 8 and a group of hydraulic lifting rods 9 are movably installed around the bottom of the lifting platform 1, a bottom plate 10 is fixedly installed at the bottom of the three groups of supporting telescopic rods 8 and a group of hydraulic lifting rods 9, an inner support component 6 is movably installed at the bottom of the lifting platform 1, and the inner support component 6 comprises a threaded rod 61, and the middle part of the threaded rod 61 is movably installed. The threaded rod 61 is movably mounted at the center of the lifting platform 1. The upper end of the threaded rod 61 is located at the top of the lifting platform 1 and is movably mounted with a threaded tube 67. The bottom position of the surface of the threaded tube 67 is provided with a passive tooth 68. The passive tooth 68 is meshed with the transmission gear 5. The bottom end of the threaded rod 61 is fixedly mounted with a linkage disk 62. The left and right sides of the linkage disk 62 are movably mounted with a first connecting plate 63. The middle part of the threaded rod 61 is located below the lifting platform 1 and is movably mounted with a contact plate 64. The left and right sides of the contact plate 64 are movably mounted with a second connecting plate 65. The connection between the two groups of the first connecting plate 63 and the second connecting plate 65 is provided with a supporting arc plate 66.

[0028] A group of external clamping parts 7 are respectively provided on the left and right sides of the lifting platform 1, and the external clamping parts 7 include movable grooves 71, and the movable grooves 71 are opened on the left and right sides of the lifting platform 1. A transmission screw 72 is movably installed inside the movable grooves 71, and a rotating piece 73 is fixedly installed on the side of the transmission screw 72 away from the center point of the lifting platform 1, and a clamping arc plate 74 is movably installed on the side of the transmission screw 72 close to the center point of the lifting platform 1. A screw hole is opened on the top of the clamping arc plate 74 and is sleeved on the transmission screw 72 through the screw hole. The two groups of clamping arc plates 74 are respectively located on the left and right sides of the two groups of supporting arc plates 66.

[0029] By adopting the above technical solution, when in use, first adjust the spacing between the two groups of supporting arc plates 66 to the minimum, then adjust the two groups of clamping arc plates 74 to the outermost side, and finally sleeve the device on the surface of the tubular pile, and sleeve the device on the tubular pile through the bottom plate 10. At this time, the threaded rod 61 and the two groups of supporting arc plates 66 are inserted into the inside of the tubular pile, and the two groups of clamping arc plates 74 are located on the outside of the tubular pile. At this time, the pile pulling work can be carried out. First, the transmission screw 72 is screwed by the rotating piece 73, so that the transmission screw 72 rotates to drive the clamping arc plate 74 to move in the moving groove 71 until The two sets of clamping arc plates 74 are all adjusted to the state of clamping the tubular pile. At this time, the motor 3 is started again. The output end of the motor 3 drives the rotating rod 4 to rotate, and the rotating rod 4 drives the transmission gear 5 to rotate. The transmission gear 5 drives the threaded tube 67 on one side to rotate while rotating. The bottom of the surface of the threaded tube 67 is provided with a passive tooth 68 meshing with the transmission gear 5, so the threaded tube 67 can be driven by the transmission gear 5. There is a thread between the threaded tube 67 and the threaded rod 61. When the threaded tube 67 rotates clockwise, the threaded rod 61 can be lowered. When the threaded tube 67 rotates counterclockwise, the threaded rod 61 rises, and when the pile is pulled out, the threaded tube 67 drives the threaded rod 61 to rise. When the threaded rod 61 rises, the linkage plate 62 moves and rises accordingly. During the rising process of the threaded rod 61, the linkage plate 62 and the bottom of the threaded rod 61 are in a fixed state, and the stop plate 64 is sleeved on the threaded rod 61 and is located at the bottom of the lifting platform 1. The stop plate 64 is restricted by the lifting platform 1 and will not move. Therefore, during the rising process of the threaded rod 61, the distance between the linkage plate 62 and the stop plate 64 will be shortened. As the distance between the linkage plate 62 and the stop plate 64 continues to shorten, the two sets of first connecting plates 63 The second connecting plate 65 will also change accordingly, and the supporting arc plate 66 connecting the first connecting plate 63 and the second connecting plate 65 will be pushed outward until the two groups of supporting arc plates 66 are in contact with the inner walls of the two sides of the tubular pile. Because the two groups of clamping arc plates 74 have been clamped on both sides of the tubular pile in advance to clamp the tubular pile, it is difficult for the two groups of supporting arc plates 66 to deform the tubular pile even if a large force is applied. The device cooperates with the inner supporting component 6 and the outer clamping component 7, which has a strong clamping ability and can prevent the tubular pile from being deformed when the tubular pile is pulled out.

[0030] Specifically, Figures 1 to 4 As shown, a slot 11 is provided at the center of the bottom plate 10, and telescopic chambers 12 are provided on the left and right side walls of the slot 11. A scraping arc plate 13 is movably installed inside the telescopic chamber 12, and one end of the scraping arc plate 13 located in the telescopic chamber 12 is fixedly connected with a spring 14. When the two groups of the scraping arc plates 13 are closed, the center is convex and a circular groove is formed at the center. The center point of the circular groove formed when the two groups of the scraping arc plates 13 are closed is on the same straight line as the center point of the lifting platform 1.

[0031] By adopting the above technical scheme, when removing the tubular pile, the bottom plate 10 is first sleeved on the tubular pile. When sleeved on the tubular pile, the two groups of scraping arc plates 13 first contact the tubular pile. The scraping arc plates 13 are installed in the inner walls on both sides of the notch 11 and are provided with springs 14, so that the scraping arc plates 13 can fit with the tubular piles when facing tubular piles of different diameters. Finally, the bottom plate 10 is sleeved on the surface of the tubular pile through the scraping arc plates 13. The bottom plate 10 is on the ground, and the scraping arc plates 13 fit on the surface of the tubular pile. The inner support component 6 and the outer clamping component 7 clamp the top of the tubular pile. Therefore, the lifting platform 1 is fixed to the tubular pile through the inner support component 6 and the outer clamping component 7. In addition, because the lifting platform 1 and the bottom plate 10 are connected by three groups of supporting telescopic rods 8 The lifting platform 1 is connected so that the height between the lifting platform 1 and the base plate 10 can be adjusted. The lifting platform 1 is supported by the hydraulic lifting rod 9. The lifting platform 1 pulls the tubular pile out of the soil during the supporting process. When the tubular pile is pulled out, the base plate 10 is close to the ground, which can protect the soil around the surface of the tubular pile to prevent the tubular pile from carrying the surrounding soil when it is pulled out. At the same time, due to the setting of the scraping arc plate 13, a large amount of soil can be avoided from being attached to the surface of the tubular pile when it is pulled out. The soil on the surface of the tubular pile can be scraped off by the scraping arc plate 13. Through the setting of the above-mentioned structure, the device can protect the soil around the pile body when pulling out the tubular pile, avoid carrying out a large amount of soil during the pile pulling process, and at the same time, the soil attached to the surface of the tubular pile can be scraped off.

[0032] Working principle: when in use, first put the device on the tubular pile, insert the tubular pile into the scraper arc plate 13, and insert the lower end of the inner support component 6 into the tubular pile, the two sets of clamping arc plates 74 are located on both sides of the tubular pile, and the transmission screw 72 is rotated by the rotating piece 73 to clamp the clamping arc plates 74 on both sides of the tubular pile, and the motor 3 is turned on to drive the threaded tube 67 to rotate through the rotating rod 4 and the transmission gear 5, and the threaded tube 67 rotates to drive the threaded rod 61 to rotate, and the threaded rod 61 tightens the linkage plate 62 and the contact plate 64 when rotating to make the first connecting plate 63 and the second connecting plate 65 on both sides open outward until the supporting arc plate 66 fits with the inner wall of the tubular pile, and then the hydraulic lifting rod 9 is started, and the lifting platform 1 is lifted by the hydraulic lifting rod 9, thereby pulling out the tubular pile clamped by the inner support component 6 and the outer clamping component 7, and the bottom plate 10 is always against the ground during the pulling process to restrict the soil, and the soil attached to the surface of the tubular pile is scraped off by the scraper arc plate 13.

[0033] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model, rather than to limit it. Although the utility model has been described in detail with reference to the aforementioned embodiments, ordinary technicians in this field should understand that they can still modify the technical solutions recorded in the aforementioned embodiments, or replace some or all of the technical features therein with equivalents. However, these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the scope of the technical solutions of the embodiments of the utility model.
