Description

Technical Field

[0001] This invention belongs to the field of dual-wheel milling desliming technology, specifically relating to a dual-wheel milling desliming and cleaning device, a dual-wheel milling tank washing machine, and a method. Background Technology

[0002] Twin-wheel trench cutters are currently the most advanced and professional equipment for diaphragm wall construction. Traditional underground wall construction equipment has limited operating depth, only able to excavate soft soil a few meters below the surface, and is not very efficient. Twin-wheel trench cutters can use different cutter heads to excavate different geological conditions, are more efficient, and can operate at greater depths. They are widely used in large-scale projects such as subway construction, underground pipeline construction, and hydropower station construction.

[0003] During twin-wheel milling, two milling wheels equipped with cutting tools are driven by a hydraulic system to rotate in opposite directions at low speed. Their milling teeth break up the surrounding rock. A hydraulic motor in the middle drives a mud pump. The rock debris and mud mixture is transported to the ground through the suction port in the middle of the cutting tools. The mud is then separated, and the purified mud is transported back into the trench, thus enabling continuous trenching until the final hole is formed.

[0004] However, when working in clay layers, twin-wheel trenching machines often accumulate a large amount of mud on the milling wheels. Furthermore, when the milling cutters rotate to deliver slurry to the suction port, the limited suction force of the port causes some slurry to adhere to the cutter surface, easily leading to a balling phenomenon between the two cutters. After prolonged operation, a large amount of mud accumulates in the gaps between the twin milling heads. As more and more mud adheres to the cutter surface, rotation becomes increasingly difficult, eventually resulting in the two cutters being completely encased in mud, directly affecting the normal operation of the milling cutters. In previous cases, cleaning the mud from the twin-wheel milling cutters was primarily done manually. However, this method requires stopping the machine and lifting it to the ground, affecting the continuity of construction and trenching efficiency, and also increasing the cost of manual mud removal. Summary of the Invention

[0005] In order to overcome the above-mentioned problems in the prior art, the present invention provides a dual-wheel milling mud removal and cleaning device, a dual-wheel milling tank washing machine and method, which are used to solve the above-mentioned problems in the prior art.

[0006] A dual-wheel milling desludge cleaning device is disclosed, wherein the device is installed on the sand suction port on the side of the milling wheel of a dual-wheel milling tank washing machine, and the device includes: a fixed installation module, a mud brush module, and a water spraying module.

[0007] The mud brush module and the water spray module are mounted on the fixed installation module.

[0008] The mud brush module is used to clean the mud from the surface of the milling cutter of the twin-wheel milling machine;

[0009] The water spray module is used to spray water to clean the surface of the milling cutter after cleaning.

[0010] In addition to the aspects and any possible implementations described above, a further implementation is provided in which the fixed installation module includes a base plate and a vertical plate connected to each other, a first fixing hole and a second fixing hole are provided on the base plate for fixing the water spray module and the mud brush module respectively, and two mounting holes are provided on the vertical plate for mounting the fixed installation module on the dual-wheel milling machine.

[0011] In addition to the aspects and any possible implementations described above, a further implementation is provided in which the mud brush module includes a wireless lifting component, a contact sensing component, and a mud scraping component, wherein the wireless lifting component and the contact sensing component are used together to adjust the height of the mud scraping component from the surface of the milling cutter.

[0012] In addition to the aspects described above and any possible implementations, a further implementation is provided in which the wireless lifting component includes a signal controller and a wireless lifter.

[0013] In addition to the aspects described above and any possible implementation, a further implementation is provided in which the signal controller includes a wireless receiver, a microprocessor, and a transmitter. The wireless receiver captures wireless control signals transmitted from the ground, the microprocessor parses these signals, and generates corresponding control commands. The control commands are transmitted to the wireless elevator via the transmitter to start or adjust its operating state.

[0014] In addition to the aspects and any possible implementations described above, a further implementation is provided in which the water spray module includes a water supply component, a rotating connecting component, a diverting component, and a spraying component. The rotating connecting component connects the water supply component and the diverting component, and the diverting component connects the spraying component. The rotating connecting component, the water supply component, and the diverting component are disposed above the first fixing hole, and the spraying component is disposed below the first fixing hole.

[0015] In addition to the aspects and any possible implementations described above, a further implementation is provided in which the water spray module further includes a rotating disk, one end of which is connected to the diversion component through the first fixing hole, and the other end of which is connected to the spray component.

[0016] In addition to the aspects and any possible implementations described above, a further implementation is provided in which the spraying component includes at least three high-pressure nozzles, which are evenly arranged on the rotating disk.

[0017] This invention also provides a mud removal and cleaning method using a twin-wheel milling tank washing machine, wherein the method is implemented using the aforementioned twin-wheel milling tank washing machine, and the method includes:

[0018] S1. After the dual-wheel milling cutter has rotated and started working, the ground personnel start the mud brush module via wireless signal;

[0019] S2. The wireless lifting component of the mud brush module is activated, the mud brush module begins to descend, and the mud scraping component of the mud brush module begins to remove mud during the rotation of the dual-wheel milling machine.

[0020] S3. When the scraping component moves to a certain height from the surface of the milling cutter, the scraping component is adjusted to rise according to the sensing of the contact sensing component to prevent damage to the milling cutter head when the scraping component rotates at high speed to remove mud;

[0021] S4. After the mud brush module completes the initial cleaning, the high-pressure water supply component in the water spraying module starts to work.

The device includes a fixed mounting module, a mud brush module, and a water spray module, with the mud brush module and water spray module mounted on the fixed mounting module. When the mud adhering to the milling wheel exceeds the height of the mud scraping end of the mud brush module, the mud forces the scraping end component to bend upwards.

[0027] Figure 2This is a schematic diagram of the dual-wheel milling mud removal and cleaning device of the present invention. Detailed Implementation

[0028] To better understand the technical solution of this invention, the content of this invention includes, but is not limited to, the specific embodiments described below. Similar technologies and methods should be considered within the scope of protection of this invention. To make the technical problems to be solved, the technical solutions, and advantages of this invention clearer, a detailed description will be provided below in conjunction with the accompanying drawings and specific embodiments.

[0029] It should be understood that the embodiments described in this invention are merely some, not all, of the embodiments of this invention. All other embodiments obtained by those skilled in the art based on the embodiments of this invention without inventive effort are within the scope of protection of this invention.

[0030] The terminology used in the embodiments of this invention is for the purpose of describing particular embodiments only and is not intended to limit the invention. The singular forms “a,” “the,” and “the” as used in the embodiments of this invention and the appended claims are also intended to include the plural forms unless the context clearly indicates otherwise.

[0031] like Figure 2 As shown, the present invention provides a mud removal and cleaning device for a twin-wheel milling machine. The device is installed on the sand suction port on the side of the milling wheel of the twin-wheel milling machine. The device includes a mud brush module and a water spray module. The mud brush module is used to clean the mud on the surface of the milling cutter of the twin-wheel milling machine. The water spray module is used to spray water to clean the cleaned surface of the milling cutter. The water spray module uses high-pressure water spray.

[0032] The fixed installation module 1 includes a connected base plate and a vertical plate. The base plate has a first fixing hole and a second fixing hole. The horizontal connection hole 12 provides a fixing platform for the wireless hydraulic lifting device 2 and the high-pressure water spray device 3. The entire mud removal and cleaning device is mounted on the sand suction port on the side of the milling wheel via the vertical bolt connection holes 13 of the fixed installation module 1. The entire system is accurately installed on the twin-wheel milling structure via the vertical bolt connection holes 13.

[0033] The mud brush module includes a wireless lifting component, a contact sensing component, and a mud scraping component 6. The wireless lifting component and the contact sensing component are used together to adjust the height of the mud scraping component 6 from the surface of the milling cutter.

[0034] The wireless lifting component includes a signal controller 14 and a wireless lifter 4. The signal controller integrates a wireless receiver, a microprocessor, and a transmitter. The wireless receiver captures wireless control signals transmitted from the ground, while the microprocessor analyzes these signals and generates corresponding control commands. These commands are then transmitted to the lifter 4 via the transmitter to activate or adjust its operating status.

[0035] The signal controller 14 is directly connected to the wireless lifting component and is responsible for receiving wireless signals from the ground monitoring system and controlling the operation of the wireless lifting component according to these signals. The wireless lifting component is implemented using a wireless lifter 4.

[0036] The top of the elastic scraper component 6 is welded to the bottom of the sensing component 5; the bottom surface of the wireless lifter 4 is connected and fixed to the contact sensing component 5 by a connecting rod 15, so that the position of the scraper component 6 in the vertical direction can be directly adjusted by the lifter 4.

[0037] The transmission signal is mainly achieved through a wireless communication protocol. When the wireless lifter 4 receives the control command from the signal control component, it activates the built-in drive mechanism, which drives the mud scraper 6 to extend vertically to the position between the two milling cutter heads on the milling wheel, ensuring the effectiveness of mud removal.

[0038] The contact sensing component 5 is used to detect the contact pressure between the scraper component 6 and the surface of the milling cutter head, thereby determining the contact between them. Based on high-precision physical resistance sensing technology, the contact sensing component 5 can sense additional pressure on the scraper component, send a signal to the signal control component, trigger the wireless lifter 4 to start, and adjust the height of the scraper component 6 to avoid potential damage from direct contact. Specifically: when the scraper component 6 contacts the milling cutter head, the sensing component 5 experiences resistance. At this point, the sensing component 5 determines that the two have made contact and sends a signal to the signal controller 14. After receiving the signal, the signal controller 14 controls the wireless lifter 4 to automatically raise the scraper component 6 by a certain distance to prevent damage to the milling cutter head during high-speed rotation.

[0039] The elastic mud scraping component 6 is composed of elastic steel wire rope segments. When the mud adhering to the milling wheel exceeds the height of the scraping end, the mud forces the scraping end to bend upward. The rebound force of the scraping component itself makes the scraping end stick tightly to the mud surface. It can effectively scrape the mud off the milling wheel in a timely manner during the rotation of the milling wheel, thus achieving automatic mud removal.

[0040] like Figure 2 As shown, the high-pressure water spraying device 3 includes a rotating connecting component 7, a flow splitting component 8, a rotating disk component 9, a high-pressure nozzle component 10, and a high-pressure water supply component 11, which is an external component.

[0041] The rotating connecting component 7 is connected to the high-pressure water supply component 11 and serves as a connecting channel for water flow from the water supply component 11 to the diversion component, ensuring that water flow can be smoothly transmitted from the water supply source to the spray system.

[0042] The diversion component 8, located after the rotating connection component 7, receives the water flow from the water supply component 11 and diverts the water flow. The present invention adopts a three-way diversion method to evenly distribute the incoming water flow to all the high-pressure nozzle components 10 on the rotating disk component 9, ensuring uniform high-pressure water spray.

[0043] The rotating disk component 9 is located under the base plate of the fixed installation module 1 and is fixedly connected to the diversion component 8 through the horizontal connection hole 12. It provides a platform for omnidirectional rotation, which is used to fix and support the high-pressure nozzle component 10, while allowing each high-pressure nozzle to rotate in multiple directions to achieve a cleaning effect without dead angles.

[0044] The high-pressure nozzle component 10 is rotatably fixed on the rotating disk component 9 and receives the water flow distributed by the diversion component 8. The present invention uses three high-pressure spray nozzles to provide a powerful water flow for the cleaning of the dual-wheel milling machine.

[0045] The high-pressure water supply component 11 is an external component responsible for providing the necessary high-pressure water flow to the entire high-pressure water spray device 3. The water inlet pipe, as part of the high-pressure water supply component 11, is used to transport water from the external water tank to the high-pressure water supply component 11. Although the water tank itself is not directly part of the high-pressure water supply component, it is an important component of the entire system, providing the necessary water source. An external high-pressure water pump or air compressor is used to pressurize the water transmitted from the water tank through the water inlet pipe before delivering it to the high-pressure water supply component 11, thereby ensuring that the high-pressure water spray device 3 has sufficient pressure for effective cleaning.

[0046] As an embodiment disclosed in this invention, such as Figure 1 As shown, the present invention also provides a dual-wheel milling tank washing machine, the tank washing machine including the aforementioned mud removal and cleaning device, the mud removal and cleaning device being fixed to the dual-wheel milling machine through two vertical bolt connection holes 13 on the mounting module 1, and the wireless hydraulic lifting mud brush device 2 and the high-pressure water spray device 3 are both arranged above the fixed mounting module 1.

[0047] As an embodiment of the present invention, the present invention also provides a mud removal and cleaning method using a twin-wheel milling tank washing machine, the method being implemented using the aforementioned twin-wheel milling tank washing machine, the method comprising:

[0048] S1. After the dual-wheel milling cutter has rotated and started working, the ground personnel start the mud brush module via wireless signal;

[0049] S2. After the mud brush module is started, the wireless lifter of the mud brush module is activated. While the dual-wheel milling machine is rotating continuously, it controls the connected mud scraping component 6 to descend from the initial position. During this process, the mud scraping component 6 continuously removes mud.

[0050] S3. During the descent of the scraper component 6, until it contacts the surface of the milling cutter, the contact sensor component 5 senses the contact resistance between the scraper and the milling cutter surface and transmits the sensing result to the signal controller 14. Upon receiving the signal, the signal controller 14 controls the wireless lifter 4 to automatically raise the position of the scraper component 6 by a certain distance to prevent damage to the milling cutter head during high-speed rotation of the scraper component 6. As the cleaning process progresses, the contact sensor component 5 continuously monitors the distance between the scraper component 6 and the milling cutter surface. When the scraper component 6 is too high due to the accumulation of mud, the mechanical signal sensed by the sensor component 5 is sent to the signal controller 14. Upon receiving the signal from the sensor component 5, the signal controller 14 indirectly adjusts the position of the scraper component 6 through the wireless lifter 4 to ensure that it is always maintained at the optimal cleaning height.

[0051] S4. After the mud brush module has been running for a period of time, preferably after three minutes, the high-pressure water spray module starts working. The high-pressure water supply component 11 starts operating and is connected to an external water source, such as a water tank, and the water pressure is increased by a high-pressure water pump or air compressor. The rotating connection component 7 receives water flow from the high-pressure water supply component 11, and the diversion component 8 ensures that each nozzle receives sufficient water flow to achieve effective spray cleaning. The water flow is evenly distributed to each high-pressure nozzle on the rotating disc for cleaning. The rotating disc component 9 starts, providing omnidirectional rotation, allowing the high-pressure nozzles to cover every corner of the milling cutter surface. The high-pressure water flow generated by these nozzles removes remaining mud and fine particles, achieving deep cleaning.

[0052] The high-pressure water spray module starts every five minutes, and each time it lasts for one minute.

[0053] S5. After the twin-wheel milling and cleaning machine completes the underwater milling operation and is lifted to the ground, the mud brush module and high-pressure water spray device 3 are activated simultaneously to perform a more thorough cleaning on the ground, ensuring that the milling cutter surface is completely clean and removing all mud and impurities.

[0054] The foregoing description illustrates and describes several preferred embodiments of the present invention. However, as previously stated, it should be understood that the present invention is not limited to the forms disclosed herein and should not be construed as excluding other embodiments. It can be used in various other combinations, modifications, and environments, and can be altered within the scope of the inventive concept described herein through the foregoing teachings or techniques or knowledge in related fields. Any modifications and variations made by those skilled in the art that do not depart from the spirit and scope of the present invention should be within the protection scope of the appended claims.
