[0019] To further understand the invention content, features and effects of this utility model, the following embodiments are provided in detail.

[0020] Please see Figure 1 The hydraulic impact rock-breaking device of this utility model includes a towable mobile vehicle 21, on which a generator, a hydraulic pump station 19, and a high-pressure water pump 18 are installed. A water supply pipe 20 is installed at the inlet of the high-pressure water pump 18. The towable mobile vehicle 21 includes a towable chassis and wheels, and can be towed by engineering machinery such as loaders or excavators. The generator and hydraulic pump station 19 includes a generator and a hydraulic pump station 19. The generator is used to generate electricity on site to provide power supply, and the hydraulic pump station 19 provides hydraulic power control.

[0021] During construction, this hydraulic impact rock breaking device requires a water tanker truck to provide water supply. The outlet of the water tanker truck is connected to the water supply pipe 20. During operation, the generator and hydraulic pump station 19 drive the high-pressure water pump 18 to operate, and the high-pressure water pump 18 boosts the water source.

[0022] An operating platform is provided at the front of the towable mobile vehicle 21, and a hydraulic jacking assembly is provided at the bottom of the operating platform. A seat 13 and a field controller 11 are installed on the operating platform. The operator sits on the seat 13 and operates the field controller 11 according to the visual situation in front to control the operation of this water pressure impact rock breaking device.

[0023] The hydraulic jacking assembly is used to hydraulically jack up the front of the device and provide jacking strength. In this embodiment, the hydraulic jacking assembly includes a support arm hinged to the operating table and a support leg 16 hinged to the outer end of the support arm. A jacking hydraulic cylinder 17 is installed between the operating table and the support arm. When the piston rod of the jacking hydraulic cylinder 17 extends, the support arm swings downward and the support leg 16 presses against the ground. Conversely, when the piston rod of the jacking hydraulic cylinder 17 retracts, the support arm swings upward and the support leg 16 leaves the ground.

[0024] A front base 14 is hinged to the front of the control panel via a pin 12, and a swing hydraulic cylinder 15 is installed between the control panel and the front base 14. By controlling the piston rod of the swing hydraulic cylinder 15 to extend and retract, the front base 14 can swing left or right around the pin 12.

[0025] A primary support arm 8 is hinged to the front base 14. A secondary support arm 6 is hinged to the front end of the primary support arm 8. A tilting base 3 is hinged to the front end of the secondary support arm 6, and a linkage mechanism 4 is provided between the secondary support arm 6 and the tilting base 3. A pitch hydraulic cylinder 10 is installed between the front base 14 and the primary support arm 8. A primary hydraulic cylinder 9 is installed between the rear ends of the primary support arm 8 and the secondary support arm 6. A secondary hydraulic cylinder 5 is installed between the secondary support arm 6 and the linkage mechanism 4. When the piston rod of the secondary hydraulic cylinder 5 is controlled to extend or retract, the tilting base 3 can be driven to tilt or retract via the linkage mechanism 4, i.e., swing up or down. When the piston rod of the primary hydraulic cylinder 9 is controlled to extend or retract, the secondary support arm 6 can be controlled to swing up or down. When the piston rod of the pitch hydraulic cylinder 10 is controlled to extend or retract, the primary support arm 8 can be controlled to swing forward or backward.

[0026] In this embodiment, the linkage mechanism 4 includes a set of rear connecting rods hinged to the front end of the secondary support arm 6 and a set of front connecting rods hinged to the front of the tilting base 3. The front end of the rear connecting rod and the rear end of the front connecting rod are connected by a hinge shaft, which passes through a shaft hole located at the front end of the piston rod of the secondary hydraulic cylinder 5. When the piston rod of the secondary hydraulic cylinder 5 extends, the linkage mechanism 4 is pushed forward, and the tilting base 3 swings downward. Conversely, when the piston rod of the secondary hydraulic cylinder 5 retracts, the linkage mechanism 4 is pulled backward, and the tilting base 3 swings upward. The tilting base 3 achieves a change in posture.

[0027] An adjustable nozzle 2 is installed on the flip-type base 3, and a high-pressure nozzle 1 is installed at the front of the adjustable nozzle 2. The adjustable nozzle 2 is connected to the outlet of the high-pressure water pump 18 through a high-pressure water pipe 7. In this embodiment, the high-pressure water pipe 7 extends from front to back into the interior of the secondary support arm 6, the primary support arm 8, and the operating platform, which reduces the exposure of the high-pressure water pipe 7 and provides a certain degree of protection for it.

[0028] Please see Figure 2 It can be seen that:

[0029] The adjustable nozzle 2 includes a first housing 2-2 with a mounting flange 2-1 at one end and a second housing 2-3 inserted and fixed to the front end of the first housing 2-2 at the rear end. A connection port is provided on the side of the second housing 2-3. It also includes a bent pipe 2-4 with a flange at the inner end and a threaded connection part 2-5 at the outer end. The flange of the bent pipe 2-4 is connected to the port on the side of the second housing 2-3. The high-pressure nozzle 1 is threadedly connected to the threaded connection part 2-5, so that the high-pressure nozzle 1 can be selected and replaced.

[0030] In this embodiment, the centerline of the first housing 2-2 is perpendicular to the centerline of the connection port on the second housing 2-3. The second housing 2-3 can be rotated and adjusted with the centerline of the first housing 2-2 as the center, and the bend 2-4 can be rotated and adjusted with the centerline of the connection port on the second housing 2-3 as the center. This allows the adjustable nozzle 2 to be adjusted according to the on-site construction requirements, thereby adjusting the initial posture of the high-pressure nozzle 1.

[0031] In this embodiment, a plurality of threaded holes are provided on the side wall of the rear end of the second housing 2-3 at equal angular intervals in the circumferential direction, and a connecting hole is provided on the side wall of the front end of the first housing 2-2. The rear end of the second housing 2-3 is inserted into the front end of the first housing 2-2 and fixedly connected by screws located in the threaded holes and the connecting holes. A sealing gasket is provided between the first housing 2-2 and the second housing 2-3 to ensure sealing. Similarly, a sealing gasket is also provided between the inner end flange of the bend 2-4 and the outer surface of the second housing 2-3 to ensure sealing.

[0032] When it is necessary to rotate and adjust the second housing 2-3, first remove the screws on the side to release the fixing relationship between the two housings. Then rotate the second housing 2-3 to the appropriate angle, and then use the aforementioned radial screws to fix the two housings again. When it is necessary to rotate and adjust the bend 2-4, it is necessary to remove the screws between its inner flange and the second housing 2-3. Then rotate the bend 2-4 to the appropriate angle, and then use screws to fix the inner flange to the second housing 2-3 again.

[0033] As shown in the figure, an interface pipe is provided on the back of the flip-type base 3. When the adjustable nozzle 2 is fixed to the flip-type base 3 through its mounting flange 2-1, the aforementioned interface pipe is connected to the interior of the adjustable nozzle. In order to ensure sealing, a sealing gasket is provided between the mounting flange 2-1 and the flip-type base 3. The front end of the high-pressure water pipe 7 is connected to the interface pipe on the back of the flip-type base 3.

[0034] Construction method:

[0035] This hydraulic impact rock breaking device is towed to the construction site by engineering machinery and parked in front of the slope where rock breaking is required. A supporting water tanker is parked near the device, and a water supply channel is established through the water supply pipe 20. The on-site operator operates the two left and right top support hydraulic cylinders 17 through the on-site controller 11, so that the two left and right support legs 16 are stably pressed on the ground. Then, the on-site operator operates the two-stage support arm to extend forward through the on-site controller 11 and adjusts the attitude of the adjustable nozzle 2 and its high-pressure nozzle 1 so that the high-pressure nozzle 1 is pointed at the rock surface that needs to be impacted and broken.

[0036] The high-pressure water pump 18 is started, and the water source is pressurized and transported to the adjustable nozzle 2 and its high-pressure nozzle 1 through the high-pressure water pipe 7. The water flow sprayed from the high-pressure nozzle 1 impacts the rock surface, causing it to break and promote the peeling. After the rock breaking at the current position is completed, the two-stage support arm is adjusted by the on-site controller to move the adjustable nozzle 2 and its high-pressure nozzle 1 to swing up and down and / or swing left and right, and to continuously carry out rock breaking construction at other rock surface positions.
