[0025] The present utility model will be described in detail below with reference to the drawings and in conjunction with embodiments. It should be noted that, without conflict, the embodiments and features in the embodiments of the present utility model can be combined with each other.

[0026] As Figure 1-2 shown, a high-pressure water jet pile head breaking device includes a main body 1, a driver, and a high-pressure water generator. The main body 1 is in the shape of a square groove and is welded by metal plates. A hanging plate is provided at the upper end of the main body 1, so that it can be suspended at a designated position by a crane or other device. A guy cable is provided at the lower end of the main body 1, and the bottom of the guy cable is connected to the ground or a counterweight. The guy cable is a steel cable, and under the traction of the guy cable, it cooperates with the crane to limit the position of the main body 1, avoiding the sway of the main body 1 during the breaking process and the problem of inaccurate breaking position. A high-pressure nozzle 2 is connected to the back of the main body 1 through a swinging mechanism. The structure of the high-pressure nozzle 2 is not limited too much in this embodiment, and a commercially available product can be used.

[0027] The high-pressure nozzle 2 extends forward into the main body 1, so as to form a protective cover through the main body 1, so that the sprayed high-pressure water will not splash in all directions. The driver is correspondingly connected to the swinging mechanism to drive the high-pressure nozzle 2 to swing back and forth. The high-pressure water is ejected from the water nozzle through the high-pressure pipe and the swinging mechanism, repeatedly impacting and cutting the surface of the pile head, breaking the surface cement to expose the internal steel bars; after the high annular breaking of the breaking limit is completed, the swinging mechanism is gradually lifted to break the pile head annularly until the highest point of the pile head, and the cycle is repeated until all the breaking is completed.

[0028] A strip-shaped relief groove corresponding to the swinging direction of the high-pressure nozzle 2 is provided on the main body 1. Preferably, both sides of the main body 1 are inclined outward to form a V-shaped protective cover, so that the water flow will not interfere with the main body 1 during the swinging process of the high-pressure nozzle 2. The inlet of the high-pressure water generator is correspondingly connected to a water source, and the outlet is connected to the high-pressure nozzle 2 through a high-pressure hose.

[0029] In an alternative embodiment, both sides and the lower part of the main body 1 are of a hollow structure, so that the splashed water flow can be quickly led out to both sides and below, avoiding accumulation inside the main body 1.

[0030] In an alternative embodiment, a support rod 9 is provided on one side of the main body 1 close to the pile head 8 to be broken. The four support rods 9 are respectively located at the four corners of the main body 1, so as to abut against the outer wall of the pile head 8 to be broken, thereby determining the distance between the high-pressure nozzle 2 and the pile head 8 to be broken, and ensuring the breaking effect of the high-pressure nozzle 2. Specifically, the guy cable inclines towards the pile head 8 to be broken, and the lower end of the guy cable is fixed to the ground or the pile head 8 to be broken according to the position to be broken of the pile head, so that the main body 1 has a tendency to move towards the pile head 8 to be broken, and then the position of the main body 1 is limited.

[0031] In an alternative embodiment, the swing mechanism includes a fixing plate 4, a hinge shaft 13, and a driving gear. The fixing plate 4 is fixed to one side of the main body 1 by welding or bolts and extends towards the back of the main body 1. On the side of the fixing plate 4, two upper plates 11 and a lower plate 12 that horizontally extend towards the other side of the main body 1 are provided. The distance between the upper plate 11 and the lower plate 12 is adapted to the high-pressure nozzle 2, and the high-pressure nozzle 2 is arranged between the upper plate 11 and the lower plate 12; a hinge shaft 13 for longitudinally hinging the upper plate 11 and the lower plate 12 is provided on the high-pressure nozzle 2. A sleeve is sleeved outside the high-pressure nozzle 2, and the sleeve extends downward and downward from the hinge shaft 13 respectively to be hinged to the upper plate 11 and the lower plate 12. The hinge shaft 13 passes upward through the upper plate 11 and then connects to a driven gear; the length of the upper plate 11 is greater than that of the lower plate 12, the driving gear correspondingly meshes with the driven gear, and the main shaft of the driving gear is rotationally connected to the upper plate 11 and correspondingly connected to a driver. Specifically, the main shaft of the driving gear passes downward through the upper plate 11, and a driver is fixed by bolts below the part of the upper plate 11 extending beyond the lower plate 12. A cover 10 corresponding to the two gears is provided above the upper plate 11 to prevent the sprayed water from overflowing and eroding the gears.

[0032] In an alternative embodiment, the driver is a hydraulic motor 3. The hydraulic motor 3 is correspondingly connected to a hydraulic station 7 to convert hydraulic pressure into torque and drive the high-pressure nozzle 2 to generate a swinging force. The hydraulic station 7 is integrally arranged on a trolley for easy movement.

[0033] In an alternative embodiment, the high-pressure water generator includes a water pump 5, a distribution box 6, and a base. The hydraulic pump of the hydraulic station 7 is connected to the distribution box 6 through a connecting wire, and it can be used by connecting to the distribution box 6 through a power cord during use. The water pump 5 and the distribution box 6 are integrally arranged on the base, and driving wheels are provided below the base for movement according to actual construction.

[0034] The above are only the preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention are within the scope of protection of the pending claims of the present invention.
