Description

Technical Field

[0001] This application relates to the field of cutting device technology, and more particularly to a device for green cutting of pile heads in cast-in-place piles. Background Technology

[0002] Cast-in-place piles are widely used in bridge pile foundation construction due to their advantages such as high bearing capacity, minimal adverse impact on adjacent buildings and the surrounding environment, and good pile quality. When pouring concrete for the pile foundation, due to sediment at the bottom of the pile, in order to ensure the quality of the pile head, the concrete pouring volume is about 1 meter higher than the top elevation of the pile during actual concrete pouring. The excess part is removed manually or mechanically, which is usually called "pile head chiseling" or "pile head breaking".

[0003] Currently, the removal of bored pile heads is often achieved through methods such as manual chiseling, mechanical crushing, or hydraulic cutting. Although these methods are widely used, they tend to generate a large amount of dust during actual construction, which has an adverse impact on the surrounding environment. Utility Model Content

[0004] In view of the shortcomings of the prior art, this utility model provides a device for green removal of the pile head of cast-in-place piles, which overcomes the shortcomings of the prior art and aims to solve the problems in the background art.

[0005] To achieve the above objectives, this application adopts the following technical solution: a device for green removal of the pile head of a cast-in-place pile, comprising a sleeve, the surface of which is provided with a dust suction mechanism, the dust suction mechanism comprising a support frame, the support frame being fixedly connected to the sleeve, a negative pressure pump being fixedly connected to the top of the support frame, the input end of the negative pressure pump being fixedly connected to the interior of the sleeve, a delivery pipe being fixedly connected to the side of the negative pressure pump away from the sleeve, a fixed bracket being fixedly connected to one side of the sleeve, a moving mechanism being provided inside the fixed bracket, two limiting mechanisms being provided at the top of the moving mechanism, the two limiting mechanisms being symmetrically distributed at the top of the moving mechanism, and a cutting mechanism being provided between the two limiting mechanisms.

[0006] In a preferred embodiment, the moving mechanism includes a first motor, which is fixedly connected to a fixed bracket. A threaded rod is fixedly connected to the output end of the first motor. The threaded rod is rotatably connected to the fixed bracket. A movable frame is threadedly connected to the outside of the threaded rod. The movable frame is slidably connected to the fixed bracket. A limit rod is slidably connected inside the movable frame. The limit rod is fixedly connected to the fixed bracket.

[0007] By adopting the above technical solution, the output end of the first motor rotates to drive the threaded rod to rotate, and the rotation of the threaded rod drives the movable frame to slide inside the fixed bracket. The limiting rod then limits the movable frame, which can better enable the movable frame to slide inside the fixed bracket.

[0008] In a preferred embodiment, the limiting mechanism includes a slider that is slidably connected to a fixed bracket. A support rod is fixedly connected to the top of the slider, and a bolt is provided on one side of the support rod. The bolt is threadedly connected to the slider, and a limiting block is fixedly connected to the side of the support rod away from the bolt.

[0009] By adopting the above technical solution, the support rod is fixed by the slider, and then the slider is slid on the surface of the fixed bracket by pulling the support rod to adjust the position of the support rod. Then, the slider is positioned by rotating the bolt to make the bolt abut against the surface of the fixed bracket, and the wire saw is limited by the limit block abutting against the surface of the support wheel. This can better limit the wire saw.

[0010] In a preferred embodiment, the cutting mechanism includes a second motor, which is fixedly connected to the movable frame. A drive wheel is fixedly connected to the output end of the second motor. A wire saw is sleeved on the inner wall of the drive wheel. Two support wheels are rotatably connected inside the wire saw. The support wheels are fixedly connected to the movable frame, and the two support wheels are symmetrically distributed on the surface of the movable frame.

[0011] By adopting the above technical solution, the output end of the second motor rotates to drive the drive wheel to rotate, which in turn drives the wire saw to rotate, and the wire saw then cuts the pile head of the cast-in-place pile. The support wheel supports the wire saw, which can better cut the pile head of the cast-in-place pile.

[0012] In a preferred embodiment, the surface of the movable frame is provided with a sliding groove, which is adapted to the slider.

[0013] By adopting the above technical solution, a sliding groove is provided on the surface of the movable frame. The sliding groove is adapted to the slider and the slider is limited by the sliding groove, which can better enable the slider to slide on the surface of the movable frame.

[0014] In one preferred embodiment, a number of guide wheels are fixedly connected inside the sleeve, and the guide wheels are arranged in a ring inside the sleeve.

[0015] By adopting the above technical solution, the guide wheel is fixed by the sleeve, and then the guide wheel rolls along the outer surface of the cast-in-place pile to ensure that the sleeve can be smoothly and accurately fitted onto the outer circumference of the cast-in-place pile. The guide wheel then limits the wire saw to prevent the wire saw from deviating, which can better fit the sleeve onto the outer circumference of the cast-in-place pile.

[0016] In a preferred embodiment, the surface of the sleeve is provided with a through hole, which is adapted to the wire saw.

[0017] By adopting the above technical solution, through holes are opened on the surface of the sleeve, and the through holes are adapted to the wire saw, so that the wire saw can cut the cast-in-place pile better.

[0018] In a preferred embodiment, a controller is fixedly connected to the top of the fixed bracket, and the controller is electrically connected to the first motor and the negative pressure pump.

[0019] By adopting the above technical solution, the controller is electrically connected to the first motor and the negative pressure pump, and the controller controls the switching of the first motor and the negative pressure pump, which can better control the switching of the first motor and the negative pressure pump.

[0020] The beneficial effects of this application are:

[0021] 1. This device for green removal of dust from the pile head of cast-in-place piles consists of a negative pressure pump, a support frame, and a delivery pipe. The negative pressure pump is fixed by the support frame, and the negative pressure pump creates negative pressure inside the delivery pipe, drawing dust from inside the casing into the delivery pipe. The dust is then transported through the delivery pipe. This avoids the problem of generating a large amount of dust during the actual construction process of traditional pile head cutting methods, thus improving practicality.

[0022] 2. This device for green cutting of the pile head of cast-in-place piles uses a slider, bolts, support rods, and limiting blocks. The slider fixes the support rod, and pulling the support rod causes the slider to slide on the surface of the fixed bracket to adjust the position of the support rod. Rotating the bolts causes them to contact the surface of the fixed bracket to position the slider. Finally, the limiting block contacts the surface of the support wheel to limit the wire saw. This avoids the problem of traditional cast-in-place pile head cutting devices being unable to limit the wire saw, thus improving practicality. Attached Figure Description

The dust collection mechanism 2 includes a support frame 22, which is fixedly connected to the sleeve 1. A negative pressure pump 21 is fixedly connected to the top of the support frame 22. The input end of the negative pressure pump 21 is fixedly connected to the interior of the sleeve 1. A delivery pipe 23 is fixedly connected to the side of the negative pressure pump 21 away from the sleeve 1. A fixed bracket 8 is fixedly connected to one side of the sleeve 1. A moving mechanism 3 is provided inside the fixed bracket 8. The moving mechanism 3 includes a first motor 32, which is fixedly connected to the fixed bracket 8. A threaded rod 33 is fixedly connected to the output end, and the threaded rod 33 is rotatably connected to the fixed bracket 8. A movable frame 34 is externally threaded to the threaded rod 33, and the movable frame 34 is slidably connected to the fixed bracket 8. A limit rod 31 is slidably connected inside the movable frame 34, and the limit rod 31 is fixedly connected to the fixed bracket 8. The output end of the first motor 32 rotates to drive the threaded rod 33 to rotate, and the rotation of the threaded rod 33 drives the movable frame 34 to slide inside the fixed bracket 8. The limit rod 31 then limits the movable frame 34, which can better enable the movable frame 34 to slide inside the fixed bracket 8.

[0030] Reference Figures 2-4The top of the moving mechanism 3 is provided with two limiting mechanisms 5, which are symmetrically distributed on the top of the moving mechanism 3. A cutting mechanism 4 is provided between the two limiting mechanisms 5. The cutting mechanism 4 includes a second motor 42, which is fixedly connected to the moving frame 34. The output end of the second motor 42 is fixedly connected to a drive wheel 41. A wire saw 44 is sleeved on the inner wall of the drive wheel 41. Two support wheels 43 are rotatably connected inside the wire saw 44. The support wheels 43 are fixedly connected to the moving frame 34. The two support wheels 43 are symmetrically distributed on the surface of the moving frame 34. The output end of the second motor 42 rotates to drive the drive wheel 41 to rotate, and the drive wheel 41 rotates to drive the wire saw 44 to rotate. The wire saw 44 then rotates to cut the pile head of the cast-in-place pile. The support wheels 43 support the wire saw 44, which can better cut the pile head of the cast-in-place pile.

[0031] Reference Figures 3-4 The limiting mechanism 5 includes a slider 51, which is slidably connected to the fixed bracket 8. A support rod 53 is fixedly connected to the top of the slider 51. A bolt 52 is provided on one side of the support rod 53, and the bolt 52 is threadedly connected to the slider 51. A limiting block 54 is fixedly connected to the side of the support rod 53 away from the bolt 52. The slider 51 fixes the support rod 53, and the slider 51 slides on the surface of the fixed bracket 8 by pulling the support rod 53 to adjust the position of the support rod 53. The bolt 52 is rotated to make the bolt 52 abut against the surface of the fixed bracket 8 to position the slider 51. The limiting block 54 abuts against the surface of the support wheel 43 to limit the wire saw 44, which can better limit the wire saw 44.

[0032] Reference Figure 4 The surface of the movable frame 34 is provided with a sliding groove 9, which is adapted to the slider 51. By providing a sliding groove 9 on the surface of the movable frame 34, which is adapted to the slider 51, and limiting the slider 51 by the sliding groove 9, the slider 51 can be slid more smoothly on the surface of the movable frame 34.

[0033] Reference Figure 2 The sleeve 1 has several guide wheels 6 fixedly connected inside, and the guide wheels 6 are distributed in a ring inside the sleeve 1. The guide wheels 6 are fixed by the sleeve 1, and then the guide wheels 6 roll along the outer surface of the cast-in-place pile to ensure that the sleeve 1 can be smoothly and accurately fitted onto the outer circumference of the cast-in-place pile. The guide wheels 6 also limit the wire saw 44 to prevent the wire saw 44 from deviating, which can better fit the sleeve 1 onto the outer circumference of the cast-in-place pile.

[0034] Reference Figures 1-2 The surface of the sleeve 1 is provided with a through hole 7, which is adapted to the wire saw 44. The through hole 7 on the surface of the sleeve 1, which is adapted to the wire saw 44, allows the wire saw 44 to cut the cast-in-place pile more effectively.

[0035] Reference Figures 1-2 A controller 10 is fixedly connected to the top of the fixed bracket 8. The controller 10 is electrically connected to the first motor 32 and the negative pressure pump 21. By connecting the controller 10 to the first motor 32 and the negative pressure pump 21, and then controlling the switching of the first motor 32 and the negative pressure pump 21, the switching of the first motor 32 and the negative pressure pump 21 can be better controlled.

[0036] Working principle: The sleeve 1 is fitted onto the outside of the pile head of the cast-in-place pile, and then the guide wheel 6 rolls along the outer surface of the pile to ensure that the sleeve 1 can be stably and accurately fitted onto the outer circumference of the pile, forming a closed working environment to prevent dust diffusion. Then, the output end of the second motor 42 rotates to drive the drive wheel 41 to rotate, and the drive wheel 41 rotates to drive the wire saw 44 to rotate, and the wire saw 44 rotates to cut the pile head. The support wheel 43 supports the wire saw 44, and the slider 51 fixes the support rod 53. Pulling the support rod 53 causes the slider 51 to slide on the surface of the fixed bracket 8 to adjust the position of the support rod 53. Finally, rotating the bolt 52 causes the bolt 52 to abut against the surface of the fixed bracket 8. The slider 51 is positioned, and the limit block 54 abuts against the surface of the support wheel 43 to limit the wire saw 44. Then, the output end of the first motor 32 rotates to drive the threaded rod 33 to rotate. The rotation of the threaded rod 33 drives the moving frame 34 to slide inside the fixed bracket 8. The limit rod 31 limits the moving frame 34. The moving frame 34 moves inside the fixed bracket 8 to drive the wire saw 44 to move. The tension of the wire saw 44 is adjusted. The support frame 22 fixes the negative pressure pump 21. The negative pressure pump 21 creates a negative pressure inside the conveying pipe 23, which draws the dust inside the sleeve 1 into the conveying pipe 23. The receiving box outside the conveying pipe 23 collects the dust, reducing the dust inside the sleeve 1.
