Description

Technical Field

[0001] This invention relates to the field of building construction technology, specifically a construction device for cutting off pipe piles in building construction. Background Technology

[0002] In the construction of building foundations, building piles are mostly concrete pipe piles. In actual construction, concrete pipe piles are usually constructed during foundation excavation. For construction convenience, the concrete pipe piles are usually made longer than the actual length. However, after being driven (or processed by other methods) to the design depth, the excess part above the foundation bottom surface must be cut off, which is called pile cutting.

[0003] Chinese invention patent CN115839085B discloses a construction device for cutting off pipe piles in building construction. It includes: a base located above the pipe pile; a main motor fixedly connected to the upper end of the base; a first electric push rod horizontally fixedly connected to the output shaft of the main motor; a second electric push rod vertically fixedly connected to the output shaft of the first electric push rod; an auxiliary motor fixedly connected to the output shaft of the second electric push rod; a cutter fixedly connected to the output shaft of the auxiliary motor; a controller for controlling the automatic operation of the construction device; and a circular groove disposed on the lower end face of the base. This invention, by placing the construction device at the end of the pipe pile exposed above ground, achieves the action of blocking the inside of the pipe pile and installing the construction device, thereby ensuring stable cutting off of the pipe pile while also achieving the purpose of preventing blockage.

[0004] However, the above-mentioned patent still has the following shortcomings in actual use: After the expansion bladder of the patent comes into contact with the inside of the pipe pile, the expansion bladder will still move down a certain distance. Once there is a sharp object on the inside of the pipe pile, the expansion bladder is very easy to be damaged and leak air. After the expansion bladder leaks air and dries up, it cannot seal the inside of the pipe pile, which in turn affects the collection of impurities during the pipe pile removal process. Summary of the Invention

[0005] The purpose of this invention is to provide a construction device for cutting off pipe piles in building construction, so as to solve the problem mentioned in the background art that when the expansion bladder is damaged, leaks air and dries up, it is impossible to seal the inside of the pipe pile, which affects the collection of impurities during the pipe pile cutting process.

[0006] The technical solution of this invention is:

[0007] A construction device for cutting off pipe piles includes a ground surface and a pipe pile body. A bearing plate is placed on top of the pipe pile body, and four clamping components are equally spaced around its center on the bearing plate.

[0012] Furthermore, the first sealing assembly includes a rotating shaft, a rotating gear, a drive motor, a drive gear, and several sealing components.

[0015] Furthermore, a rubber pad is provided on the inner wall of the arc-shaped clamping block.

[0016] Furthermore, two triangular supports are symmetrically arranged at the top of the vertical rod, and the tops of the two triangular supports are connected to the bottom of the horizontal plate.

[0017] This invention provides an improved construction device for cutting off pipe piles in building construction, which has the following improvements and advantages compared with the prior art:

[0018] Firstly, this invention uses a drive motor to rotate a drive gear, which in turn rotates a rotating gear. This rotating gear then drives several arc-shaped guide grooves to rotate synchronously. Because the sliding column slides against the arc-shaped guide grooves, the sliding column moves forward as the guide grooves rotate. The sliding column then moves a sliding rod forward, which in turn moves an arc-shaped plate forward. The arc-shaped plate then moves a collection box forward until its outer wall contacts the inner wall of the pipe pile body. This synchronous forward movement of the collection boxes in several sealing components makes it suitable for sealing pipe pile bodies of different inner diameters. The collection chamber can collect impurities. Compared to the method of sealing with an inflatable bladder, the collection box will not leak air when it comes into contact with sharp objects, ensuring stable sealing of the pipe pile body. This ensures stable collection of impurities generated during the removal of the pipe pile body. There is a certain gap between the collection boxes of two adjacent sealing components in the first sealing assembly. Therefore, the second sealing assembly is staggered with the first sealing assembly. The center of the collection box in each sealing component of the second sealing assembly is located between the collection boxes of two adjacent sealing components in the first sealing assembly, ensuring that all impurities entering the pipe pile body can be collected, thus ensuring collection quality.

[0019] Secondly, this invention uses a hydraulic push rod to move the mounting block downwards, which in turn moves the cutting disc downwards until it aligns with the exposed part of the pipe pile body. Then, the cutting motor drives the cutting disc to rotate at high speed. Simultaneously, the adjusting motor drives the rotating rod to rotate. The rotating rod, through two adjusting rods, moves the sliding blocks in the two cutting components closer together. The sliding blocks move the cutting discs in the two cutting components closer together until they contact the pipe pile body for cutting. At the same time as the cutting disc is cutting, the rotating motor drives the cutting disc to rotate around the center of the bearing plate, facilitating the circumferential cutting of the pipe pile body by the cutting disc.

[0020] Thirdly, the present invention is equipped with several rollers to reduce the friction between the collection box and the inner wall of the pipe pile body. The use of rollers also facilitates the collection box to move up and down along the pipe pile body. Attached Figure Description

Detailed Implementation

[0038] The present invention will now be described in detail, and the technical solutions in the embodiments of the present invention will be clearly and completely described. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0039] This invention provides an improved construction device for cutting off pipe piles in building construction, such as... Figures 1-14 As shown, the structure includes a ground surface 1 and a pipe pile body 2. A bearing plate 3 is placed on top of the pipe pile body 2. The bearing plate 3 has four clamping components 4 evenly spaced around its center. One end of each clamping component 4 abuts against the outer wall of the pipe pile body 2. A rotating platform 31 is located at the top center of the bearing plate 3. A ring rack 32 is fitted onto the top outer wall of the rotating platform 31. A rotary motor 33 is vertically mounted on the top of the bearing plate 3. A rotary gear 34 is mounted on the output shaft of the rotary motor 33. The rotary gear 34 interacts with the ring rack. 32. The rotating table 31 has a vertical rod 35 at its top, and a cutting component 5 at its top. The cutting component 5 is used to cut the pipe pile body 2. The bearing plate 3 has a lifting component 6 at its bottom, which is located inside the pipe pile body 2. The bottom end of the lifting component 6 has a sealing mechanism 7, which is used to seal the inner side of the pipe pile body 2. By placing the bearing plate 3 on top of the pipe pile body 2, with the center of the bearing plate 3 aligned with the center of the pipe pile body 2, the four clamping components 4 work to clamp the pipe pile. The outer wall of the main body 2 is clamped against the ground, and then the lifting component 6 drives the sealing mechanism 7 to move downward. The sealing mechanism 7 moves downward inside the pipe pile body 2 to a height below ground level 1. Then, the sealing mechanism 7 performs a sealing operation on the inner side of the pipe pile body 2. Subsequently, the rotary motor 33 drives the rotary gear 34 to rotate. The rotary gear 34 drives the rotary table 31 to rotate via the ring rack 32. The rotary table 31 drives the cutting component 5 to rotate via the vertical rod 35. While rotating, the cutting component 5 cuts the part of the pipe pile body 2 that is exposed above ground level 1, thereby achieving the purpose of circumferential cutting and removal of the pipe pile body 2. During the removal process, some impurities will enter the inner side of the pipe pile body 2. At this time, the sealing mechanism 7 collects the impurities that have entered the pipe pile body 2 to prevent impurities from causing blockage inside the pipe pile body 2. Compared with the method of sealing by inflating an expansion bladder, the sealing mechanism 7 will not leak air when it comes into contact with sharp objects, ensuring stable sealing inside the pipe pile body 2, and thus ensuring stable collection of impurities generated during the removal of the pipe pile body 2. The entire device has high operational stability.

[0040] Specifically, the cutting assembly 5 includes a horizontal plate 51, a support frame 52, an adjusting motor 53, a rotating rod 54, two adjusting rods 55, and two cutting components 56. The horizontal plate 51 is horizontally positioned on top of the vertical rod 35. The two cutting components 56 are symmetrically arranged on the horizontal plate 51. Each cutting component 56 includes a through groove 561, a sliding block 562, a mounting bracket 563, a hydraulic push rod 564, a mounting block 565, a cutting motor 566, a cutting disc 567, and two sliding grooves 568. The through groove 561 is formed on the horizontal plate 51, and the two... The slide grooves 568 are symmetrically arranged at the bottom of the horizontal plate 51. The sliding block 562 is slidably mounted on the two slide grooves 568. The mounting bracket 563 is located at the bottom of the sliding block 562. The hydraulic push rod 564 is vertically mounted on the inner wall of the mounting bracket 563. The mounting block 565 is located on the output end of the hydraulic push rod 564. The cutting motor 566 is vertically mounted at the bottom of the mounting block 565. The cutting disc 567 is mounted on the output shaft of the cutting motor 566. The support bracket 52 is mounted on the outer wall of the horizontal plate 51. The adjustment... The motor 53 is vertically mounted at the top of the support frame 52. The rotating rod 54 is mounted on the output shaft of the adjusting motor 53. One end of each of the two adjusting rods 55 is hinged to the end of the rotating rod 54, and the other end of each of the two adjusting rods 55 is hinged to the top of the sliding block 562 in each of the two cutting components 56. The hydraulic push rod 564 drives the mounting block 565 to move downward, and the mounting block 565 drives the cutting disc 567 downward until it corresponds to the point where the pipe pile body 2 protrudes from the ground 1. Then, the cutting motor 566 drives the cutting disc 567 to move downward. 7. High-speed rotation: While the cutting disc 567 rotates, the adjusting motor 53 drives the rotating rod 54 to rotate. The rotating rod 54 uses two adjusting rods 55 to drive the sliding blocks 562 in the two cutting components 56 to move closer to each other. The sliding blocks 562 drive the cutting discs 567 in the two cutting components 56 to move closer to each other until they contact the pipe pile body 2 for cutting. At the same time as the cutting disc 567 is cutting, the rotating motor 33 drives the cutting disc 567 to rotate around the center of the bearing plate 3, which facilitates the cutting disc 567 to perform circumferential cutting of the pipe pile body 2.

[0041] Specifically, the lifting assembly 6 includes a lifting box 61, a lifting plate 62, and two lifting components 63. The lifting box 61 is installed at the bottom of the bearing plate 3. Two inspection doors 64 are hinged to one outer wall of the lifting box 61. The two lifting components 63 are symmetrically arranged inside the lifting box 61, and the bottom ends of the two lifting components 63 extend to the bottom of the lifting box 61. The lifting plate 62 is installed at the bottom of the two lifting components 63. The operation of the two lifting components 63 drives the lifting plate 62 to move downward within the pipe pile body 2, which facilitates the lifting plate 62 to drive the sealing mechanism 7 to move downward within the pipe pile body 2 to a height below the ground level 1. This facilitates the sealing mechanism 7 to seal the area below the cutting edge of the cutting disc 567. The two inspection doors 64 facilitate the maintenance of the components inside the lifting box 61.

[0042] Specifically, each of the lifting components 63 includes a first lifting seat 631, a second lifting seat 632, a pulley 633, a winding shaft 634, a winding roller 635, a lifting motor 636, a steel rope 637, and a lifting ring 638. The first lifting seat 631 and the second lifting seat 632 are spaced apart inside the lifting box 61. The pulley 633 is rotatably mounted on the top of the first lifting seat 631. The winding shaft 634 is rotatably mounted on the top of the second lifting seat 632. The winding roller 635 is mounted on the winding shaft 634. The lifting motor 636 is horizontally mounted on the outer wall of the second lifting seat 632, and the output shaft of the lifting motor 636 is connected to the winding shaft 634. The lifting ring 638 is mounted on the top of the lifting plate 62. The top end of the rope 637 is connected to the take-up roller 635, and the bottom end of the steel rope 637 passes through the pulley 633 and is connected to the lifting ring 638. The lifting motor 636 drives the take-up shaft 634 and the take-up roller 635 to rotate. The take-up roller 635 drives the top end of the steel rope 637 to be in the unwinding state. The steel rope 637 drives the lifting ring 638 to move downward using the pulley 633. The lifting ring 638 drives the lifting plate 62 to move downward within the pipe pile body 2. Then, the lifting plate 62 drives the sealing mechanism 7 to move downward within the pipe pile body 2 to a height lower than the ground 1. After the circumferential cutting of the pipe pile body 2 is completed, the lifting motor 636 reverses its operation to drive the lifting ring 638 and the lifting plate 62 to move upward. The lifting plate 62 drives the sealing mechanism 7 to move upward and reset.

[0043] Specifically, the sealing mechanism 7 includes a first fixing plate 71, a second fixing plate 72, a first sealing component 73, a second sealing component 74, two first fixing posts 75, and two second fixing posts 76. The two first fixing posts 75 are symmetrically arranged at the bottom of the lifting plate 62. The first fixing plate 71 is installed at the bottom of the two first fixing posts 75. The two second fixing posts 76 are symmetrically arranged at the bottom of the first fixing plate 71. The second fixing plate 72 is installed at the bottom of the two second fixing posts 76. The first sealing component 73 and the second sealing component 74 have the same structure and are respectively installed on the first fixing plate 71 and the second fixing plate 72, with the first sealing component 73 and the second sealing component 74 being staggered. The lifting plate 62 is driven by the two first fixing posts 75. The first fixed plate 71 moves downward, and the second fixed plate 72 moves downward synchronously driven by the two second fixed columns 76. The first fixed plate 71 and the second fixed plate 72 drive the first sealing component 73 and the second sealing component 74 to move downward within the pipe pile body 2 to a height below ground level 1. The first sealing component 73 and the second sealing component 74 can be used to seal pipe pile bodies 2 with different inner diameters. In this way, the first sealing component 73 and the second sealing component 74 can collect impurities that enter into the pipe pile body 2, preventing impurities from causing blockages in the pipe pile body 2. The staggered arrangement between the first sealing component 73 and the second sealing component 74 facilitates the collection of impurities falling into the gaps in the first sealing component 73 by the second sealing component 74, ensuring that all impurities entering the pipe pile body 2 can be collected, ensuring collection quality.

[0044] Specifically, the first sealing assembly 73 includes a rotating shaft 731, a rotating gear 732, a drive motor 733, a drive gear 734, and a plurality of sealing components 735. The plurality of sealing components 735 are equally spaced around the center of the first fixed disk 71. Each sealing component 735 includes a sliding groove 736, a sliding rod 737, an arc-shaped plate 738, and a collection box 739. The sliding groove 736 is formed on the first fixed disk 71. The sliding rod 737 is slidably mounted on the sliding groove 736, and its front end extends to the outside of the first fixed disk 71. The arc-shaped plate 738 is mounted on the front end of the sliding rod 737, and the collection box 739 is mounted on the arc-shaped plate 738. On the outer wall, the collection box 739 has a collection cavity 7391. The rotating shaft 731 is rotatably mounted at the top center of the first fixed disk 71. The rotating gear 732 is mounted on the rotating shaft 731. The rotating gear 732 has several arc-shaped guide grooves 7321 evenly spaced around its center. A sliding column 7322 is slidably mounted in the arc-shaped guide grooves 7321. The bottom of the sliding column 7322 is connected to the rear end of the sliding rod 737. The drive motor 733 is vertically mounted on the top of the first fixed disk 71. The drive gear 734 is mounted on the output shaft of the drive motor 733 and meshes with the rotating gear 732. The drive motor 733 drives the drive gear 734. The rotation of the drive gear 734 drives the rotating gear 732 to rotate, which in turn drives several arc-shaped guide grooves 7321 to rotate synchronously. Because the sliding column 7322 slides against the arc-shaped guide grooves 7321, the sliding column 7322 moves forward as the arc-shaped guide grooves 7321 rotate. The sliding column 7322 drives the sliding rod 737 to move forward, which in turn drives the arc-shaped plate 738 to move forward. The arc-shaped plate 738 drives the collection box 739 to move forward until its outer wall contacts the inner wall of the pipe pile body 2. This allows the collection boxes 739 in several sealing components 735 to move forward synchronously, making them suitable for sealing pipe pile bodies 2 with different inner diameters. The collection chamber 7391 can remove impurities. Compared to the method of sealing with an inflatable bladder, the collection box 739 will not leak air when it comes into contact with sharp objects, ensuring stable sealing inside the pipe pile body 2. This ensures stable collection of impurities generated during the removal of the pipe pile body 2. There is a certain gap between the collection boxes 739 in the two adjacent sealing components 735 in the first sealing assembly 73. Therefore, the second sealing assembly 74 is staggered with the first sealing assembly 73. The center of the collection box 739 in each sealing component 735 in the second sealing assembly 74 is located between the collection boxes 739 in the two adjacent sealing components 735 in the first sealing assembly 73, ensuring that all impurities entering the pipe pile body 2 can be collected, ensuring collection quality.

[0045] Specifically, the outer wall of the collection box 739 away from the arc plate 738 is provided with an installation groove 7392, and a plurality of rollers 7393 are provided on the installation groove 7392. The rollers 7393 are in contact with the inner wall of the pipe pile body 2. The provision of a plurality of rollers 7393 reduces the frictional force of the collection box 739 directly contacting the inner wall of the pipe pile body 2, and the use of rollers 7393 facilitates the collection box 739 to move up and down along the pipe pile body 2.

[0046] Specifically, the clamping assembly 4 includes a clamping groove 41, an arc-shaped clamping block 42, a screw slide 43, and an L-shaped rod 44. The clamping groove 41 is located at the bottom of the bearing plate 3, and the top of the bearing plate 3 has a through groove 45 that communicates with the clamping groove 41. The arc-shaped clamping block 42 is slidably mounted on the clamping groove 41. The screw slide 43 is horizontally positioned on the top of the bearing plate 3. The top end of the L-shaped rod 44 is mounted on the moving end of the screw slide 43, and the bottom end of the L-shaped rod 44 passes through the through groove 45 and connects to the top of the arc-shaped clamping block 42. The working of the screw slide 43 drives the L-shaped rod 44 to move, and the L-shaped rod 44 drives the arc-shaped clamping block 42 to slide on the clamping groove 41. The inner wall of the arc-shaped clamping block 42 moves to contact the outer wall of the pipe pile body 2, thereby stably clamping the bearing plate 3 on the top of the pipe pile body 2.

[0047] Specifically, a rubber pad is provided on the inner wall of the arc-shaped clamping block 42; the rubber pad prevents the arc-shaped clamping block 42 from directly contacting the outer wall of the pipe pile body 2.
