[0037] The following is combined with Figure 1-5 This application is described in further detail.

[0038] The embodiment of the present application discloses a device for breaking the head of a bored pile.

[0039] Example 1

[0040] Reference Figure 1 , 2 A bored pile head breaking device comprises a main body base 1, which is L-shaped as a whole, and rollers 13 are rotatably arranged on both sides of the L-shaped bottom, a groove is arranged on one side of the L-shaped angle surface of the main body base 1 (two L-shaped handles are fixedly arranged on the other side of the groove of the main body base 1), and a reciprocating screw 2 is rotatably arranged at the upper and lower ends of the groove, a second motor 12 is fixedly arranged in the middle of the upper end surface of the main body base 1, and the output shaft of the second motor 12 movably passes through the main body base 1 and is fixedly connected to the top of the reciprocating screw 2 through a coupling.

[0041] Through the above arrangement, the handle on one side of the main base 1 is pushed to make the main base 1 move on the ground surface with the roller 13 as support. At the same time, the output shaft of the second motor 12 drives the reciprocating screw 2 to rotate, providing power for the subsequent adjustment mechanism 4.

[0042] Reference Figure 2 , 4The adjusting mechanism 4 includes a pillar 41 inserted into the groove of the main body base 1, a rotating hole 42 is opened in the middle of the pillar 41, the rotating hole 42 runs through the upper and lower ends of the pillar 41, and the inner wall of the rotating hole 42 is provided with an internal thread, and the internal thread of the rotating hole 42 is threadedly connected to the outer surface of the reciprocating screw 2, and a fixing plate 44 is welded and fixed on the side of the top of the pillar 41 away from the main body base 1, a second annular groove 46 is opened on the upper end surface of the fixing plate 44, and an inner groove is arranged in the middle of the second annular groove 46, a gripping rod 47 is movably arranged in the second annular groove 46, a circular protrusion is arranged in the middle of the gripping rod 47, and the circular protrusion abuts against the inner groove of the second annular groove 46 to maintain longitudinal fixation, and an electric push rod 49 is fixedly provided on the bottom of the gripping rod 47 protruding from the lower end surface of the fixing plate 44, a bottom groove 45 is opened in the center of the lower end surface of the fixing plate 44, and a rotating rod 48 is rotatably connected in the bottom groove 45, and one end of the rotating rod 48 away from the bottom groove 45 is fixedly connected to one side of the upper end surface of the electric push rod 49.

[0043] It should be noted that the arc of the second annular groove 46 is at least 230°, so that the cutting area of ​​the subsequent saw blade 11 covers the entire pile head. The top of the gripping rod 47 protrudes from the upper end surface of the fixing plate 44 and the outer surface is provided with multiple layers of rubber rings to increase friction. A telescopic cover is provided around the telescopic shaft on one side of the electric push rod 49 to protect the telescopic shaft and prevent the wear of the telescopic tube caused by dust and stone ejection when breaking the pile head.

[0044] Through the above arrangement, the rotation of the reciprocating screw 2 drives the support 41 to move back and forth along the surface of the reciprocating screw 2, thereby driving the fixed plate 44 to perform a lifting operation. When the fixed plate 44 is lifted or lowered, a push-pull force is applied to the rotating rod 48, and then the rotating rod 48 transmits the push-pull force to the electric push rod 49, causing the electric push rod 49 to move up and down. At the same time, a person pushes the grip rod 47 to move in an arc along the second annular groove 46, and the grip rod 47 synchronously drives one end of the electric push rod 49 to move in an arc, causing the electric push rod 49 to rotate around the rotating rod 48 as the center.

[0045] Reference Figure 2 , 34. A rotating seat 43 is welded and fixed to the side of the bottom of the pillar 41 away from the main base 1, and a rotating rod is fixed in the middle of the rotating seat 43. The fixing mechanism 3 includes a first plug hole 33 and a second plug hole 35 rotatably connected to the surface of the rotating rod of the rotating seat 43. A first clamping plate 31 is fixedly provided on the side of the first plug hole 33 away from the rotating seat 43, and a second clamping plate 32 is fixedly provided on the side of the second plug hole 35 close to the first clamping plate 31. The first clamping plate 31 and the second clamping plate 32 are both semicircular, and the opposite side is an arc surface so as to be connected to form a circular through groove, and a first annular groove 37 is provided in the middle of the arc surface of the first clamping plate 31 and the second clamping plate 32. A plurality of longitudinal leakage grooves 38 (the number of leakage grooves 38 is at least eight) are provided in the grooves of the two first annular grooves 37. The leakage grooves 38 pass through the bottom of the first clamping plate 31 and the second clamping plate 32 and are connected to the outside. A perfusion interface 36 is fixedly provided at one end of the groove of the two first annular grooves 37 away from the leakage grooves 38.

[0046] It should be noted that the first socket 33 and the second socket 35 are plugged into each other, and the first socket 33 and the second socket 35 are fixedly provided at the other end of the first clamp 31 and the second clamp 32 away from the rotating seat 43, and the plug 34 is inserted and fixed in the first socket 33 and the second socket 35 away from the first socket 33, 35, and a pipe is set on the top of the perfusion interface 36 and connected to the water source.

[0047] Through the above arrangement, the first socket 33 and the second socket 35 rotate around the rotating seat 43, thereby driving the first clamping plate 31 and the second clamping plate 32 to rotate synchronously to achieve opening and closing. When the first clamping plate 31 and the second clamping plate 32 are closed, the cast-in-place pile head is clamped and fixed. At the same time, the casting interface 36 injects water flow, and the water flow flows into the multiple leakage grooves 38 through the first annular groove 37, thereby contacting the outer surface of the cast-in-place pile head, thereby achieving the effect of cooling and absorbing dust.

[0048] Reference Figure 2 , 5 A fixed block 5 is fixedly provided at the end of the telescopic shaft of the electric push rod 49 (the telescopic cover of the electric push rod 49 surrounds one side of the fixed block 5 to achieve sealing of the telescopic shaft), a connecting hole 7 is opened on the upper end surface of the fixed block 5, and the connecting hole 7 passes through the lower end surface of the fixed block 5 and is connected to the outside, a first motor 6 is fixedly provided on the upper end surface of the fixed block 5 by screws, and the output shaft of the first motor 6 is movably inserted in the connecting hole 7, a connecting column 8 is movably inserted in the connecting hole 7, and the top of the connecting column 8 is fixedly connected to the output shaft of the first motor 6, a fixing disk 10 is welded and fixed to the bottom end of the connecting column 8, a saw blade 11 is fixedly provided on the surface of the connecting column 8 located on the upper end surface of the fixing disk 10, and a limit plate 9 is fixedly provided on the surface of the connecting column 8 located on the upper end surface of the saw blade 11.

[0049] Through the above arrangement, the fixed block 5 is driven by the electric push rod 49 to rotate synchronously. The rotation of the fixed block 5 drives the connecting column 8 to make the saw blade 11 revolve around the rotating rod 48. At this time, the first motor 6 rotates to make the connecting column 8 rotate around the first motor 6, so that the saw blade 11 rotates around its own center. As the electric push rod 49 extends and retracts, it drives the connecting column 8, so that the saw blade 11 is inserted into the through groove range of the first clamp plate 31 and the second clamp plate 32.

[0050] Among them, the device also includes a coupling, a pipeline, a first motor 6, and a second motor 12, which are all existing technologies, and their structural principles are not described in detail, and the first motor 6 is set as a DC motor, which is suitable for long-term continuous working environment.

[0051] The implementation principle of a bored pile head breaking device according to an embodiment of the present application is as follows: when using the device, the handle on one side of the main body base 1 is pushed to push the main body base 1 to the position of the pile head that needs to be broken, and the first clamping plate 31 and the second clamping plate 32 are kept directly above the pile head. The reciprocating screw 2 is rotated by controlling the second motor 12, and the rotation of the reciprocating screw 2 drives the fixed plate 44 and the rotating seat 43 to descend synchronously.

[0052] As the rotating seat 43 drives the first clamping plate 31 and the second clamping plate 32 to continue to descend, when they descend to the breaking line, the second motor 12 stops running and remains stationary. At this time, the personnel rotate the first clamping plate 31 and the second clamping plate 32 to close them, thereby abutting and clamping the outer surface of the pile head. After the closure is completed, the plug 34 is used to insert the first socket 33 and the second socket 35 on one side to fix the pile head and the main base 1, and then the external water source is turned on and injected into the injection interface 36 through the pipeline. The injection interface 36 sprays water to the first annular groove 37, which is then diverted by the leakage groove 38 and contacts the outer surface of the pile head to keep it moist.

[0053] As the second motor 12 stops and the fixed plate 44 drops synchronously, the first motor 6 is started to rotate, and the first motor 6 drives the connecting column 8 to cause the saw blade 11 to rotate at high speed. At this time, the person pushes the grip 47 to rotate along the second annular groove 46, so that the fixed block 5 drives the saw blade 11 to rotate, and the saw blade 11 rotates while revolving around the pile head, thereby cutting the pile head. At this time, the electric push rod 49 is controlled to perform a continuous and slow contraction action, so that the fixed block 5 drives the saw blade 11 to contract synchronously, so that the saw blade 11 is gradually inserted into the pile head for cutting, and the continuous infusion of water reduces the high temperature generated by the cutting of the saw blade 11, and solidifies the dust at the same time.

[0054] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
