Description

Technical Field

[0001] This application relates to the field of engineering construction technology, and in particular to a pile head cutting device. Background Technology

[0002] After the pile foundation construction is completed, the concrete pile head needs to be broken to form a pile cap foundation that meets the requirements. Currently, the main method is to use a cutting machine to cut around the concrete pile head to complete the breaking work. However, when the cutting machine is cutting around the concrete pile head, it is impossible to control its own posture stability, which affects the cutting effect and efficiency of the concrete pile head. Summary of the Invention

[0003] This application aims to at least solve one of the technical problems existing in the prior art. To this end, this application proposes a pile head cutting device to solve the problem of unstable posture of the cutting machine when performing circumferential cutting on the pile head.

[0004] This application provides a pile head cutting device, including: a base, a top frame, a main water tank, and at least two cutting components evenly arranged around the periphery of the top frame;

[0005] The base has a circular track at the top, the top frame has a cylindrical structure and its bottom slides in conjunction with the circular track. Both the base and the top frame are used to be fitted onto the outside of the pile head.

[0006] The main water tank is a cylindrical structure coaxially arranged with the top frame and placed inside the top frame;

[0007] The cutting assembly includes a cutting machine and a water pipe connected to the main water tank. The top frame has a cutting opening to avoid the cutting machine. The body of the cutting machine is rotatably mounted on the outside of the top frame via a rotating shaft extending in a vertical direction, so that the blade of the cutting machine moves in a direction close to or away from the cutting opening. The water outlet of the water pipe is positioned directly opposite the blade, and the water inlet of the water pipe is connected to the interior of the main water tank.

[0008] Based on the pile head cutting device, the circular track allows the top frame and the cutting machine on it to rotate smoothly around the pile head, thus ensuring the cutting efficiency and stability of the pile head. The main water tank and water pipes not only clean and cool the blades during operation, but also make the top frame more stable when rotating around the pile head by the weight of the main water tank. The base, top frame, and main water tank can all be cylindrical structures coaxial with the pile head, by setting the main water tank, top frame, and base to be coaxial.

[0009] Optionally, at least three positioning posts are evenly arranged around the bottom of the base, the positioning posts extending vertically and having a pointed tip at the bottom.

[0010] Furthermore, based on the aforementioned positioning column and tip design, the base can be easily fixed to the ground surface around the pile head, providing a more reliable and stable working platform for the entire pile head cutting device.

[0011] Optionally, the base includes a top ring, a bottom ring, and an adjusting rod arranged in a vertical direction, the circular track is disposed on the top ring, and the bottom ring and the top ring are connected by the adjusting rod which can extend and retract in a vertical direction.

[0012] Furthermore, based on the aforementioned base, the overall height of the base can be adjusted according to the height of the pile head, thereby adjusting the height of the cutting machine on the top frame and further improving the versatility of the entire pile head cutting device.

[0013] Optionally, the bottom of the circular track is provided with a cleaning hole that communicates with the outside.

[0014] Furthermore, the opening of the aforementioned cleaning holes allows the top frame to rotate more smoothly on the circular track, reducing the impact of dust generated by the cutting machine when cutting the pile head, and further improving the stability and reliability of the entire pile head cutting device.

[0015] Optionally, the main water tank is located below the center of gravity of the top frame.

[0016] Furthermore, based on the aforementioned location of the main water tank, the stability and reliability of the top frame rotating on the circular track can be further improved, and the main water tank can use its own weight to further reduce the shaking of the entire top frame during rotation.

[0017] Optionally, the cutting machine is connected to the rotating shaft via a first swing arm that extends a predetermined distance in the horizontal direction.

[0018] Furthermore, based on the aforementioned first swing arm, the rotation of the first swing arm around the pivot axis can be used to move the cutting machine closer to or further away from the cutting opening on the top frame.

[0019] Optionally, the cutting assembly further includes a cutting bracket, the cutting machine is mounted on the cutting bracket, the top of the cutting bracket extends vertically to a position near the top of the top frame, and the top of the cutting bracket is connected to the rotating shaft via a second swing rod extending horizontally by a predetermined distance.

[0020] Furthermore, based on the aforementioned cutting bracket, a stable installation position can be provided for the cutting machine, ensuring smoother operation and movement towards or away from the top frame. It also buffers vibrations caused by the blade's operation, ensuring the stability and reliability of the entire pile head cutting device. The second swing arm at the top of the cutting bracket allows for convenient control of the cutting machine towards or away from the cutting edge. Specifically, the first swing arm can be parallel to the second swing arm, allowing the rotating shaft, the first swing arm, the cutting bracket, and the second swing arm to form a quadrilateral support structure. Alternatively, the first swing arm and the second swing arm can be arranged opposite each other or in other ways, as long as the overall stability of the cutting bracket is improved.

[0021] Optionally, the cutting bracket is provided with a water distribution tank, the middle section of the water pipe is located in the water distribution tank, and the water distribution tank is provided with a water pump connected to the water pipe.

[0022] Furthermore, based on the aforementioned water distribution tank configuration, the water supply from the pipes can be maintained even when the water in the main water tank is depleted. The water in the distribution tank can be used to replenish the water supply in a timely manner, and it can also be used to cool the water pump, thereby improving the flexibility and reliability of the entire pile head cutting device. It should be noted that the amount of water in the distribution tank is significantly less than that in the main water tank, which ensures both a continuous water supply from the pipes and that the overall weight of the cutting support does not affect the stability of the pile head cutting device during operation.

[0023] Optionally, a fixing buckle is provided on the water outlet end of the water pipe, and the fixing buckle is fixed on the cutting machine or the cutting bracket so that the water outlet end of the water pipe forms a set angle with the blade.

[0024] Furthermore, based on the aforementioned fixing buckle, the angle of the water outlet end of the water pipe can be fixed, so that the water sprayed from the water pipe can clean the cutting position of the blade and the pile head in a timely manner. At the same time, the water flow can be used to rinse and cool the blade without affecting the stability of the blade itself.

[0025] Optionally, the top of the top frame is provided with an operating lever and a control button. The operating lever extends radially along the top frame and at least one end extends to the outside of the top frame. The control button is electrically connected to the cutting machine via a wire from inside the cutting bracket.

[0026] Furthermore, based on the aforementioned setup and placement of the control levers and buttons, it is easier for workers to operate the cutting machine and the top frame, allowing for simultaneous operation of two tasks and improving the efficiency and safety of pile head cutting.

[0027] The technical solution provided in this application has the following advantages compared with the prior art:

[0028] The pile head cutting device in this application utilizes a circular track to allow the top frame and the cutting machine on it to rotate smoothly around the pile head, thereby ensuring the cutting efficiency and stability of the pile head. The main water tank and water pipes not only clean and cool the blades during operation, but also utilize the weight of the main water tank to make the top frame more stable when rotating around the pile head. The base, top frame, and main water tank can all be cylindrical structures coaxial with the pile head, by setting the main water tank, top frame, and base to be coaxial. Attached Figure Description

[0034] Some embodiments of this application are described below with reference to the accompanying drawings. Those skilled in the art should understand that these embodiments are merely illustrative of the technical principles of this application and are not intended to limit the scope of protection of this application.

[0035] Currently, the main method for breaking pile heads is to use a cutting machine to make a circumferential cut around the pile head. However, when the cutting machine is making a circumferential cut around the pile head, it is difficult to control its own posture stability, which affects the cutting effect and efficiency of the pile head.

[0036] Based on this, this application provides a pile head cutting device that utilizes a circular track to allow the top frame and the cutting machine on the top frame to rotate smoothly around the pile head, thereby ensuring the cutting efficiency and stability of the pile head. The main water tank and water pipes not only clean and cool the working blades, but also utilize the weight of the main water tank to make the top frame more stable when rotating around the pile head. The base, top frame, and main water tank can all be cylindrical structures coaxial with the pile head, by setting the main water tank, top frame, and base to be coaxial.

[0037] The present application will be specifically described below through specific embodiments.

[0038] Reference Figure 1 and Figure 2 As shown, this embodiment provides a pile head cutting device, including: a base 1, a top frame 2, a main water tank 3, and at least two cutting components 4 evenly arranged around the top frame 2; the top of the base 1 is provided with a circular track 11, the top frame 2 is a cylindrical structure, and its bottom is slidably engaged with the circular track 11. Both the base 1 and the top frame 2 are used to fit on the outside of the pile head; the main water tank 3 is a cylindrical structure coaxially arranged with the top frame 2 and placed inside the top frame 2; the cutting components 4 include a cutting machine 41 and a water pipe 42 connected to the main water tank 3. The top frame 2 has a cutting opening for avoiding the cutting machine 41. The body of the cutting machine 41 is rotatably mounted on the outside of the top frame 2 through a rotating shaft 46 extending in the vertical direction, so that the blade 411 of the cutting machine 41 moves in a direction close to or away from the cutting opening. The water outlet of the water pipe 42 is set directly opposite the blade 411, and the water inlet of the water pipe 42 is connected to the inside of the main water tank 3.

[0039] The pile head cutting device provided in this embodiment can utilize the circular track 11 to make the top frame 2 and the cutting machine 41 on the top frame 2 rotate smoothly around the pile head, thereby ensuring the cutting efficiency and stability of the pile head. Through the setting of the main water tank 3 and water pipe 42, not only can the working blade 411 be cleaned and cooled, but the weight of the main water tank 3 can also make the top frame 2 more stable when rotating around the pile head. The base 1, the top frame 2 and the main water tank 3 can all be cylindrical structures coaxial with the pile head, by setting the main water tank 3, the top frame 2 and the base 1 to be coaxial.

[0040] Optionally, at least three positioning posts 12 are evenly arranged around the bottom of the base 1, the positioning posts 12 extend vertically and have a pointed tip 121 at the bottom.

[0041] Furthermore, based on the aforementioned positioning column 12 and tip 121, the base 1 can be easily fixed on the ground surface around the pile head, providing a more reliable and stable working platform for the entire pile head cutting device.

[0042] In some embodiments, the base 1 includes a top ring 13, a bottom ring 14, and an adjusting rod 15 arranged in a vertical direction. A circular track 11 is disposed on the top ring 13. The bottom ring 14 and the top ring 13 are connected by an adjusting rod 15 that can extend and retract in a vertical direction. The adjusting rod 15 can be a telescopic rod with a built-in locking structure. Specifically, the telescopic length of the adjusting rod 15 can be locked and fixed by a self-locking thread or an additional locking structure.

[0043] Furthermore, based on the aforementioned base 1, the overall height of the base 1 can be adjusted according to the height of the pile head, thereby adjusting the height of the cutting machine 41 on the top frame 2, further improving the versatility of the entire pile head cutting device.

[0044] Continue to refer to Figure 1 and Figure 2 As shown, a cleaning hole 111 communicating with the outside is provided at the bottom of the circular track 11. When the cutting machine 41 cuts the pile head, a large amount of dust will fly out and fall into the circular track 11. In order to discharge the dust in the circular track 11 and avoid the accumulation of dust affecting the stability of the top frame 2 when rotating, the dust is pushed by the rotation of the top frame 2. In conjunction with the multiple cleaning holes 111 evenly opened along the periphery of the circular track 11, the dust in the circular track 11 can be quickly discharged to the outside.

[0045] Furthermore, based on the opening of the cleaning hole 111, the top frame 2 can rotate more smoothly on the circular track 11, reducing the impact of dust generated by the cutting machine 41 when cutting the pile head, and further improving the stability and reliability of the entire pile head cutting device.

[0046] Continue to refer to Figure 1 As shown, the main water tank 3 is located below the center of gravity of the top frame 2.

[0047] Furthermore, based on the aforementioned location of the main water tank 3, the stability and reliability of the top frame 2 when rotating on the circular track 11 can be further improved, and the main water tank 3 can use its own weight to further reduce the shaking of the entire top frame 2 when rotating.

[0048] In some embodiments, the cutting machine 41 is connected to the rotating shaft 46 via a first swing rod 43 extending a predetermined distance in the horizontal direction. The rotating shaft of the blade 411 on the cutting machine 41 is parallel to the rotating shaft 46. The rotating shaft 46 is mounted on the top frame 2. The first swing rod 43 connects the rotating shafts of the two parallel blades 411 and the rotating shaft 46.

[0049] Furthermore, based on the aforementioned first swing rod 43, the rotation of the first swing rod 43 around the rotating shaft 46 can be used to move the cutting machine 41 closer to or further away from the cutting opening on the top frame 2.

[0050] In other embodiments, the cutting machine 41 can also be connected to the rotating shaft 46 via gear transmission, as long as the blade 411 of the cutting machine 41 can move in a direction close to or away from the cutting opening.

[0051] Continue to refer to Figure 1 As shown, the cutting assembly 4 also includes a cutting bracket 44, the cutting machine 41 is mounted on the cutting bracket 44, the top of the cutting bracket 44 extends vertically to a position close to the top of the top frame 2, and the top of the cutting bracket 44 is connected to the rotating shaft 46 by a second swing rod 45 extending horizontally by a set distance.

[0052] Furthermore, based on the aforementioned cutting bracket 44, a stable installation position can be provided for the cutting machine 41, ensuring that the cutting machine 41 is more stable during operation and movement in the direction close to or away from the top frame 2. At the same time, it can also provide a buffer for the vibration caused by the blade 411 during operation, ensuring the stability and reliability of the entire pile head cutting device. Through the setting of the second swing rod 45 at the top of the cutting bracket 44, the cutting machine 41 can be easily controlled in the direction close to or away from the cutting edge. Specifically, the first swing rod 43 can be set parallel to the second swing rod 45, so that the rotating shaft 46, the first swing rod 43, the cutting bracket 44 and the second swing rod 45 together form a quadrilateral bracket structure. The first swing rod 43 can also be set opposite to the second swing rod 45 or arranged in other ways, as long as the overall stability of the cutting bracket 44 can be improved.

[0053] Continue to refer to Figure 1 and Figure 2 As shown, the cutting bracket 44 is equipped with a water distribution tank 5, the middle section of the water pipe 42 is located in the water distribution tank 5, and the water distribution tank 5 is equipped with a water pump that is connected to the water pipe 42.

[0054] Furthermore, based on the aforementioned water distribution tank 5, the water supply from the water pipe 42 can be maintained even when the water in the main water tank 3 is depleted. The water in the distribution tank 5 can be used to replenish the water supply in a timely manner, and at the same time, the water in the distribution tank 5 can be used to cool the water pump, thereby improving the flexibility and reliability of the entire pile head cutting device. It should be noted that the amount of water in the distribution tank 5 is significantly less than that in the main water tank 3, which ensures both the continuous water supply to the water pipe 42 and the overall weight of the cutting bracket 44 does not affect the stability of the pile head cutting device during operation.

[0055] In some embodiments, a fixing buckle 421 is provided on the water outlet end of the water pipe 42. The fixing buckle 421 is fixed on the cutting machine 41 or the cutting bracket 44 so that the water outlet end of the water pipe 42 forms a set angle with the blade 411. Specifically, the water outlet end of the water pipe 42 and the blade 411 form an acute angle or an obtuse angle, as long as it is inclined. The clean water sprayed from the water outlet end of the water pipe 42 can at least partially reach the position where the pile head is cut.

[0056] Furthermore, based on the aforementioned fixing buckle 421, the angle of the water outlet end of the water pipe 42 can be fixed, so that the water sprayed from the water pipe 42 can clean the cutting position of the blade 411 and the pile head in a timely manner. At the same time, the water flow can be used to rinse and cool the blade 411 without affecting the stability of the blade 411 itself.

[0057] In a further embodiment, the fixing buckle 421 can adjust the cross-section of the water pipe 42 by adjusting its tightness, thereby controlling the water flow of the water pipe 42, or even the opening and closing of the water flow.

[0058] In some embodiments, the top of the top frame 2 is provided with an operating lever 21 and a control button 22. The operating lever 21 extends radially along the top frame 2 and at least one end extends to the outside of the top frame 2. The control button 22 is electrically connected to the cutting machine 41 via a wire from inside the cutting bracket 44. The operating lever 21 can extend radially along the top frame 2 or extend in a direction forming a certain angle with the radial direction, as long as it can increase the torque and facilitate the worker to rotate the top frame 2. The control button 22 can be located near the operating lever 21. Specifically, when the worker's palm holds the operating lever 21, the thumb can press the control button 22.

[0059] Furthermore, based on the above-mentioned setting method and setting position of the operating lever 21 and control button 22, it is more convenient for workers to operate the rotation of the cutting machine 41 and the top frame 2, and two tasks can be operated at the same time, improving the efficiency and safety of pile head cutting.
