Description

Technical Field

[0001] The utility model relates to the technical field of construction engineering, and relates to a water jet non-destructive demolition device. Background Technique

[0002] Water jet non-destructive demolition of concrete is a new construction technology that uses high-pressure water jet technology to break concrete. During the use of buildings, due to limited early design experience or new functional requirements, it is necessary to reconstruct existing structures, including reinforcement, demolition, strengthening, etc. Water jets are often used to demolish structures, and part of the steel bars in the existing structure are retained.

[0003] The working principle of water jet non-destructive demolition: The water jet non-destructive demolition concrete technology mainly pressurizes water to about 120 MPa through a high-power high-pressure water pump, and then shoots the high-pressure water onto the concrete through a precisely controlled output device. The high-speed water flow acts on the concrete surface and its micropores, converting pressure into speed. When the tensile strength of the ground is lower than the force generated by the water jet, the concrete will break. Since the surface of the steel bar is relatively dense and has no micropores, the high-pressure water cannot penetrate, so the steel bar is not damaged under the action of the water jet, ensuring the integrity and stability of the internal structure.

[0004] At present, a large amount of water is wasted during the water jet non-destructive demolition process, and the water impact on the concrete will generate relatively large noise. There is an urgent need for a water jet non-destructive demolition device to solve the above problems. Content of the Utility Model

Specific embodiments

[0022] Please refer to Figures 1-3 for a further description of the embodiments of the present utility model.

[0023] A water jet non-destructive demolition device includes a vehicle body 1, a water tank 2, a water pumping assembly and a jetting assembly. The water tank 2 is fixed on the vehicle body 1, the water pumping assembly is installed in the water tank 2, and the jetting assembly is communicated with the water pumping assembly.

[0024] The jetting assembly includes a first hose 5, a waterproof cover 10 and high-pressure nozzles 12. A water chamber 11 is formed inside the top of the waterproof cover 10. One end of the first hose 5 is communicated with the water pumping assembly, the other end is fixed on the waterproof cover 10 and communicated with the water chamber 11. A plurality of high-pressure nozzles 12 are provided and are all fixed on the inner top of the waterproof cover 10 and communicated with the water chamber 11.

[0025] The vehicle body 1 facilitates driving the entire device to move. The water tank 2 is used to store clean water. The first hose 5 is long enough to allow the entire jetting assembly to move. When the device works, the waterproof cover 10 is placed at the demolition site of the concrete structure, and then the water pumping assembly is started. The water pumping assembly will pump the water in the water tank 2 into the first hose 5 of the jetting assembly. Then, the high-pressure water flow will enter the water chamber 11 inside the top of the waterproof cover 10, and finally be sprayed at the demolition site of the concrete structure through a plurality of high-pressure nozzles 12. By using the high-speed water flow acting on the concrete surface and its micropores inside, the pressure is converted into speed. When the tensile strength of the ground is lower than the force generated by the water jet, the concrete will break. Since the surface of the steel bar is relatively dense and has no micropores, the high-pressure water cannot penetrate, so the steel bar is not damaged under the action of the water jet, ensuring the integrity and stability of the internal structure.

[0026] Since the entire operation of water jet cutting the concrete is located inside the waterproof cover 10, it can prevent the concrete fragments and water splashes generated during work from splashing onto the staff, ensuring the safety of the staff during work, and at the same time reducing the noise generated during work.

[0027] An absorbing component is provided inside the waterproof cover 10, and the water outlet end of the absorbing component penetrates through the upper side wall of the water tank 2.

[0028] ​When water jet cutting concrete, the water absorption component is started. The water absorption component will suck part of the waste water after cutting the concrete back into the water tank 2, which can reduce water resource waste. Moreover, during the water absorption process, part of the noise will also be sucked away. The noise is mixed in the flowing water, consuming the energy of the noise, which can further reduce noise.

[0029] An adjustment component for adjusting the height and angle of the waterproof cover 10 is installed on the vehicle body 1. The setting of the adjustment component facilitates the adjustment of the height and angle of the waterproof cover 10, so as to achieve the purpose of adjusting the height and angle of the high-pressure nozzle 12, and facilitate the water jet demolition treatment of concrete in different directions.

[0030] The adjustment component includes an electric lifting rod 6, a robotic arm 7, a reduction motor 8 and a fixture 9. The electric lifting rod 6 is vertically fixed on the vehicle body 1. The robotic arm 7 faces the outside of the vehicle body 1 and is installed at the top of the electric lifting rod 6. The reduction motor 8 is fixed at the bottom of the robotic arm 7. The fixture 9 is fixed between the output end of the reduction motor 8 and the top of the waterproof cover 10. The end of the first hose 5 is clamped in the fixture 9.

[0031] When the adjustment component is in use, the electric lifting rod 6 is powered on. The electric lifting rod 6 will drive the components on it to rise or fall, so as to realize the height adjustment of the spraying component. When precise adjustment of the spraying component is required, the robotic arm 7 can be started to move the spraying component to the designated position. After moving, the robotic arm 7 is turned off. At this time, the robotic arm 7 positions the spraying component here. The fixture 9 is used to clamp the first hose 5 and the waterproof cover 10.

[0032] When the angle of the spraying component needs fine adjustment, the reduction motor 8 is powered on. The reduction motor 8 will drive the fixture 9 and the waterproof cover 10 to rotate slowly, so as to realize the angle adjustment of the spraying component. The normal use of the first hose 5 is not affected during the adjustment process.

[0033] The water absorption component includes an annular water pipe 13, a water suction pipe 14, a second hose 15 and a water suction pump 16. The annular water pipe 13 is fixed inside the waterproof cover 10. A number of water suction pipes 14 are provided and are all communicated with the annular water pipe 13. The water suction pump 16 is fixed above the side wall of the water tank 2, and the water outlet end of the water suction pump 16 penetrates the side wall of the water tank 2. One end of the second hose 15 penetrates the waterproof cover 10 and is communicated with the annular water pipe 13, and the other end is fixed at the water inlet end of the water suction pump 16.

[0034] It should be noted that a filter screen needs to be installed on each water suction pipe 14 before use. When the water absorption component is in use, the water suction pump 16 is powered on. After the water suction pump 16 works, the water in the waterproof cover 10 will be sucked into the water suction pipe 14 equipped with a filter screen. The filter screen can filter the water to prevent the water suction pipe 14 from being blocked. Then the filtered water will enter the annular water pipe 13, and then the water will be returned to the water tank 2 through the second hose 15 and the water suction pump 16. These waters can be reused, thus reducing water resource waste.

[0035] A liquid level alarm 17 is installed on the water tank 2, and the test end of the liquid level alarm 17 is located inside the water tank 2.

[0036] The preset water level can be set for the liquid level alarm 17. When the test end of the liquid level alarm 17 detects that the actual water level is lower than the preset water level, an alarm sound will be emitted for water shortage warning to prevent affecting the normal operation of the pumping component.

[0037] The pumping component includes a high-pressure water pump 3 and a water outlet pipe 4. The high-pressure water pump 3 is fixed to the inner bottom of the water tank 2, and the water outlet pipe 4 is fixed at the water outlet end of the high-pressure water pump 3 and communicated with the first hose 5;

[0038] When the pumping component is in use, the high-pressure water pump 3 is powered on. The high-pressure water pump 3 will pump the water in the water tank 2 into the water outlet pipe 4, and the water outlet pipe 4 will then transport the water into the first hose 5 to provide a jet water source for the jet component.
