When the device is used for pile cutting operation on the top of a cast-in-place pile, a user firstly assembles the device (namely, two adjacent frames 1 are installed through bolts and are connected end to form a ring shape as shown in fig. 1) according to the diameter of the cast-in-place pile and referring to a construction reference parameter table, then the user loads the device onto an excavator through a connecting chain on the frames 1, and at the moment, the device is ready to work.
After the preparation work of the device is finished, a user controls the excavator to bring the device up and move to the position above the cast-in-place pile, and the user controls the device to gradually move downwards through the excavator arm until the device is sleeved on the cast-in-place pile and moves downwards to the position where the pile is required to be cut off, and the user controls the excavator arm to stop driving the device to move downwards.
In order to ensure that the part of the device under the cast-in-place pile is not deflected when the pile is cut, the drill rods 3 distributed in the circumferential array are prevented from being extruded in different sizes and directions, the service life of the device is prolonged, and the following operations are needed:
The user inputs hydraulic oil into the device through the excavator, because the hydraulic push rods 2 distributed in the circumferential array are connected in series, the telescopic ends of the hydraulic push rods 2 distributed in the circumferential array extend simultaneously, taking the leftmost hydraulic push rod 2 as an example, the telescopic ends of the hydraulic push rods 2 drive the sliding ring 701 to move rightwards through two pins 702, the sliding ring 701 drives two upward transmission frames 703 to synchronously move rightwards, taking the upper transmission frame 703 as an example, the transmission frame 703 drives the sliding rod 4 to move rightwards, the sliding rod 4 drives the transmission ring 704 to move rightwards through a limiting pin 708, the transmission ring 704 extrudes and drives the clamping plate 6 to move rightwards through a spring until the clamping plate 6 contacts the surface of the filling pile, the sliding rod 4 continues to move rightwards along with the transmission ring 704 and the clamping plate 6, and extrudes the spring between the transmission ring 704 and the clamping plate 6, and in the process, the sliding rod 4 and the fixed rod 5 relatively displace, the fixed rod 5 slides into the sliding rod 4, as the sliding rod 4 continues to move rightwards, the sliding rod 4 contacts and extrudes to the inclined surface at the upper side of the first limiting block 707, the sliding rod 4 extrudes and drives the first limiting block 707 to move downwards, meanwhile extrudes the spring between the first limiting block 707 and the adjacent fixed rod 5 until the first limiting block 707 moves to the combined groove on the sliding rod 4, the spring between the first limiting block 707 and the adjacent fixed rod 5 drives the first limiting block 707 to move upwards, the first limiting block 707 extrudes and drives the limiting pin 708 to move upwards, after the limiting pin 708 moves upwards out of the straight sliding groove part of the combined groove on the sliding rod 4, the spring in a compressed state between the transmission ring 704 and the clamping plate 6 drives the transmission ring 704 and the limiting pin 708 to move leftwards, the limiting pin 708 is extruded by the inclined surface of the trapezoid sliding groove part of the combined groove on the sliding rod 4, the clamping plate 6 is fixed to the filling pile and the clamping of this device, and the clamping plate 6 that upside circumference distributes is fixed to the part that needs to cut down of filling pile, and the clamping plate 6 that downside circumference distributes is fixed to this device whole through the filling pile to strengthen this device stability at the during operation, lock clamping plate 6 through first stopper 707 and slide bar 4 cooperation, guaranteed the stability of this device when fixed, prevent that this device from appearing the skew at the during operation, thereby prevent that filling pile section from appearing the skew.
In the rightward moving process of the sliding rod 4, the limit grooves distributed on the sliding rod 4 at equal intervals continuously extrude and drive the limit rod 706 to move backwards, and stretch the tension spring between the limit rod 706 and the fixing plate 705 until the sliding rod 4 stops moving leftwards, and the limit rod 706 and the adjacent limit grooves on the sliding rod 4 are in limit fit to limit and lock the sliding rod 4, so that the fixing of the clamping plate 6 to the cut part of the cast-in-place pile is increased.
In the clamping and fixing step, when the telescopic end of the hydraulic push rod 2 drives the sliding ring 701 to move rightwards, the sliding ring 701 drives the drill rod 3 to synchronously move rightwards through a spring between the sliding ring 701 and the drill rod 3 until the right end of the drill rod 3 contacts the surface of the cast-in-place pile, the drill rod 3 stops moving rightwards, the distance between the sliding ring 701 and the drill rod 3 gradually decreases along with the continuous extension of the telescopic end of the hydraulic push rod 2, and meanwhile, the spring between the sliding ring 701 and the drill rod 3 is extruded, so that the right end of the drill rod 3 is ensured to press the surface of the cast-in-place pile.
After the clamping and fixing step is finished (taking the upper left driving ring 704 as an example), as the driving ring 704 continues to move leftwards, the driving ring 704 contacts with the inclined surface of the first limiting frame 709, as the driving ring 704 continues to move leftwards, the driving ring 704 presses and drives the first limiting frame 709 to move forwards, the first limiting frame 709 drives the pin 702 to move forwards, and stretches a tension spring between the pin 702 and the sliding ring 701 until the pin 702 slides outwards from the telescopic end of the hydraulic push rod 2, and after the fixing step is finished, both pins 702 move outwards from the telescopic end of the hydraulic push rod 2, springs between the sliding ring 701 and the drill rod 3 press and drive the sliding ring 701 to move leftwards, the upper assembly block 811 and the lower assembly block 811 stretch outwards under the drive of the springs between the upper assembly block and the telescopic end of the hydraulic push rod 2, as the telescopic ends of the hydraulic push rod 2 continue to extend outwards, the telescopic ends of the hydraulic push rod 2 drive the two assembling blocks 811 to move rightward, taking the upper assembling block 811 as an example, the left end of the drill rod 3 contacts and presses to the upper inclined surface of the assembling block 811, the assembling block 811 is pressed to move downward, and meanwhile, springs between the assembling block 811 and the telescopic ends of the hydraulic push rod 2 are pressed until the assembling block 811 moves leftwards into an assembling groove at the left end of the drill rod 3, the springs between the assembling block 811 and the telescopic ends of the hydraulic push rod 2 drive the assembling block 811 to move upwards and be embedded into an assembling groove at the upper side of the left end of the drill rod 3, at the moment, the right side of the telescopic ends of the hydraulic push rod 2 also contacts and is embedded into the left side of the drill rod 3, the telescopic ends of the hydraulic push rod 2 and the drill rod 3 are converted into a fixedly connected relation, and the switching step is completed.
