Description

Technical Field

[0001] This invention relates to the field of railway sleeper grouting technology, and more specifically, to a smart-controlled microwave grouting and grouting operation vehicle for railway sleeper sulfur anchoring. Background Technology

[0002] A smart microwave grouting and injection vehicle for sulfur anchoring of railway sleepers is a highly automated sulfur anchoring agent grouting and injection vehicle based on microwave heating technology. After the railway sleepers are laid in the project's track laying base, the operator pours the anchoring agent raw materials from the storage device into the microwave grouting device according to the specified mixing ratio of sulfur anchoring agent. Then, the operating device of the smart microwave grouting and injection vehicle for sulfur anchoring of railway sleepers is started, and the vehicle begins to operate automatically according to the internal program. First, the water drilling device drills holes on the laid sleepers according to the specifications. Then, the hot air gun on the drying and seating device dries the holes with a high temperature of 600°C. The microwave grouting device can uniformly melt the sulfur anchoring agent raw materials through a high-speed stirring motor and a microwave generator. After the microwave grouting device has run for the predetermined program time, when the grout changes from thin to thick to a liquid gel, it is automatically injected into the dried holes. Finally, the vehicle moves to achieve precise movement of one sleeper to start the next work cycle. This patent relates to a dual-purpose drying and seating device for a railway sleeper sulfur anchoring intelligent control microwave grouting and injection operation vehicle. The device allows operators to sit down, and the shielding device and lighting can overcome weather difficulties to a certain extent and enable nighttime operation. The fence set around the operation vehicle can prevent operators from falling off the vehicle.

[0003] Existing microwave grouting methods are divided into traditional stir-frying and electromagnetic grouting, with traditional stir-frying remaining the most commonly used. The traditional stir-frying method involves heating sand in a pot to 100℃-120℃, then adding cement and stirring while heating to approximately 130℃. Finally, sulfur and paraffin are added, and stirring continues while heating to 150℃-160℃. During the grouting process, the temperature must be strictly controlled, not exceeding 180℃, and constant stirring is necessary to ensure the grout is evenly mixed and reaches a liquid-gel consistency before use. The electromagnetic stir-frying method is a further improvement on the traditional method. It primarily utilizes electromagnetic heating and an intelligent control system to achieve efficient and environmentally friendly sulfur anchoring grouting for railway sleepers. In use, sulfur, cement, sand, and paraffin are added to the grouting pot in the correct proportions. Electromagnetic induction heating technology is used for precise temperature control, ensuring the temperature does not exceed 150℃ to prevent sulfur combustion. During the grouting process, a stirring device continuously stirs the material to ensure even heating, while a tail gas purification device treats the generated waste gas, reducing SO2 emissions. The electromagnetic heating device is simple to operate and highly automated, making it suitable for sulfur anchoring construction of railway sleepers, thus improving work efficiency and safety.

[0004] Traditional frying methods have the following drawbacks: high labor intensity requiring continuous manual stirring; difficulty in temperature control, easily leading to sulfur combustion or sublimation, affecting quality; SO2 gas production during the boiling process, polluting the environment and posing health risks; significant resource waste due to the use of wood for heating; and harsh operating environment with risks of burns and fires. Electromagnetic boiling methods involve heavy equipment that is difficult to move and transport, and the level of automation still needs improvement. During operation, operator comfort is insufficient, and heating efficiency and speed need improvement. Furthermore, energy utilization efficiency needs optimization, and heating uniformity is inadequate. There is still room for improvement in equipment and operation, and environmental protection and safety can be enhanced. In addition, the device needs further refinement to adapt to complex weather conditions and continuous, uninterrupted nighttime operation.

[0005] Therefore, there is an urgent need for a highly automated, environmentally friendly, convenient, efficient, and continuous construction intelligent microwave grouting and injection vehicle for railway sleeper sulfur anchoring, in order to achieve low carbon and energy saving, improve production efficiency, and reduce harmful gas emissions, thereby improving the traditional railway sleeper sulfur anchoring grouting method.

[0027] This invention also provides a method for sulfur anchoring grouting of railway sleepers. The method is implemented using the aforementioned intelligent-controlled microwave grouting and grouting vehicle for sulfur anchoring of railway sleepers. The method includes:

[0028] Step 1: After the sleepers are laid in the project's track laying base, the operators take out the anchoring agent raw materials and water from the storage device;

[0029] Step 2: Open the feeding funnel and add the anchoring agent raw materials and water into the reaction vessel through the feeding funnel according to the specified mixing ratio of the sulfur anchoring agent.

When the temperature inside the reactor reaches 160 degrees, the stirring component will be automatically started. The anchoring agent raw material is stirred through the output end of the stirring motor.

[0031] Step 4: Start the operation of the intelligent microwave grouting and injection vehicle for sulfur anchoring of the sleepers through the operating mechanism;

[0034] Step 7: After the intelligent microwave grouting and injection vehicle for sulfur anchoring of the sleeper is accurately positioned, move the intelligent microwave grouting and injection vehicle for sulfur anchoring of the sleeper to a position where the hole opened in the sleeper is below the discharge funnel of the microwave grouting mechanism, open the discharge funnel, and inject the slurry in the reactor into the dried hole.

[0036] Preferably, step 3 includes a temperature control method for the microwave cooking mechanism, the temperature control method comprising:

[0037] S1. Obtain the measured temperature of the material in the reactor at the material measuring point using a sensor;

[0038] S2. Calculate the difference between the measured temperature of the material at the material measuring point in the reactor and the preset target temperature;

[0039] S3. Compare whether the absolute value exceeds 1℃. If the absolute value is ≥1℃, increase the oscillation output power of the magnetron in the microwave cooking mechanism through the preset precise programmable algorithm to achieve heating of the material. If the absolute value is <1℃, decrease the oscillation output power of the magnetron in the microwave cooking mechanism to a constant state through the preset precise programmable algorithm so that the measured temperature at the material temperature measuring point in the reactor fits the preset target temperature curve.

[0040] The beneficial effects of this invention are as follows:

[0041] This invention discloses a smart-controlled microwave grouting and injection vehicle for railway sleeper sulfur anchoring. Compared to existing traditional frying methods and electromagnetic or open-flame grouting processes, the microwave grouting mechanism of this vehicle offers advantages such as smaller equipment size, less space occupation, significantly simplified operation, and more flexible and precise temperature control. Furthermore, the microwave grouting mechanism of this vehicle uses microwaves to make the heated material itself the heating element, heating it simultaneously from the inside out, achieving the desired heating effect in a short time. This ensures that the anchoring agent raw materials and water are heated evenly. During microwave heating, polar molecules such as water molecules in the material absorb microwaves and convert them into heat energy. Aside from a small amount of transmission loss, there are almost no other losses, significantly improving heating efficiency while reducing energy consumption and SO2 emissions, and enhancing safety.

[0042] Furthermore, the coordinated design of its power mechanism, operating mechanism, transmission mechanism, microwave slurry cooking mechanism, storage mechanism, drying and seating mechanism, shielding mechanism, and paired drilling mechanism further enhances the automation level of the work vehicle. The shielding mechanism effectively protects the equipment from sun and rain, prevents operators from suffering heatstroke or catching a cold, and avoids falls from the work vehicle. The drying and seating mechanism not only quickly dries the drilled holes but also provides a seat for operators to rest, further improving operational comfort and safety.

[0043] This work vehicle is flexible in its configuration and reasonable in its design, offering high levels of operational comfort and safety. It features high automation and intelligence, high heating efficiency, and strong applicability. It overcomes the shortcomings of traditional stir-frying methods and electromagnetic slurry boiling processes, greatly improving the production efficiency of the sleeper maintenance section.

[0112] This invention also provides a method for sulfur anchoring grouting of railway sleepers. The method is implemented using the aforementioned intelligent-controlled microwave grouting and grouting vehicle for sulfur anchoring of railway sleepers. The method includes:

[0113] Step 1: After the sleepers are laid in the project's track laying base, the operators take out the anchoring agent raw materials and water from the storage mechanism 10;

[0114] Step 2: Open the feeding funnel 19 and add the anchoring agent raw materials and water into the reaction vessel 22 through the feeding funnel 19 according to the specified mixing ratio of the sulfur anchoring agent.

[0115] Step 3: Turn on the microwave power supply module of the microwave slurry cooking mechanism 6 and operate it according to the temperature control method of the microwave slurry cooking mechanism 6. When the temperature inside the reactor 22 reaches 160 degrees, the stirring component will be automatically started. The anchoring agent raw material is stirred through the output end of the stirring motor 21. During the stirring process, the anchoring agent raw material is mixed evenly with the material under the action of microwave radiation reaction.

[0116] Step 4: Rotate the keyhole 11-6 of the control mechanism 1 to start the work vehicle, then press the program control button 11-1 on the control panel 11 of the control mechanism 1, and push the control lever 11-4. The work vehicle will start to run automatically.

[0117] Step 5: After the water drill mechanism is positioned to the opening position on the sleeper, the water drill bit of the drilling mechanism 4 starts working to open the sleeper. The transverse guide rail 51-1 and transverse slide 51-3 of the transverse sliding component 51, the longitudinal guide rail 52-1 and longitudinal slide 52-3 of the longitudinal sliding component 52, the adjusting rod 47-3 of the height adjustment component, and the vertical sliding gear guide rail 48 are adjusted to position the opening position on the sleeper. After the opening position is positioned, the water drill bit starts working to open the sleeper.

[0118] Step 6: After the water drill bit of the drilling mechanism 4 makes a hole in the sleeper, the operating mechanism 1 drives the fan 53-3 in the drying and sitting mechanism 7 to operate. The hollow mechanical arm 54 is positioned at the hole, and the hot air gun 56 begins to dry the hole with a high temperature of 600℃.

[0119] Step 7: After the intelligent microwave grouting and injection vehicle for sulfur anchoring of the sleeper is precisely positioned, when the grout in the reactor 22 changes from thin to thick into a liquid gel, move the intelligent microwave grouting and injection vehicle for sulfur anchoring of the sleeper until the hole opened in the sleeper is located below the discharge funnel 24 of the microwave grouting mechanism 6. When the vehicle moves, the position of the hole can be positioned by a cross-shaped laser using an infrared laser device. After precise positioning, open the discharge funnel 24 and inject the grout in the reactor 22 into the dried hole.

[0120] Step 8: After the grout is injected into the hole, the intelligent microwave grouting and injection vehicle for sulfur anchoring of the sleepers is moved and positioned on the next sleeper to be opened for the next operation.

[0121] According to the above-mentioned railway sleeper sulfur anchoring grouting method, step 3 includes a temperature control method for the microwave grouting mechanism 6, the temperature control method including:

[0122] S1. The measured temperature of the material in the reactor 22 at the material measuring point is obtained through sensor 58;

[0123] S2. Calculate the difference l(t) between the measured temperature of the material at the material measuring point in reactor 22 and the preset target temperature;

[0124] S3. Compare whether the absolute value of l(t) exceeds 1℃. If the absolute value of l(t) is ≥1℃, increase the oscillation output power of the magnetron 16 in the microwave cooking mechanism 6 through the preset precise program control algorithm to achieve heating of the material. If the absolute value of l(t) is <1℃, decrease the oscillation output power of the magnetron 16 in the microwave cooking mechanism 6 to a constant state through the preset precise program control algorithm so that the measured temperature at the material temperature measuring point in the reactor 22 fits the preset target temperature curve.

[0125] In a preferred embodiment, the microwave cooking mechanism 6 involved in S3 uses a preset precise control algorithm. Temperature control is achieved by using a temperature sensor 58 to collect the difference between the measured temperature of the material at the measuring point and the preset target temperature. This difference is then used to control the PWM output via PID regulation, effectively simulating continuous signal changes. The signal is sent to the magnetron 16, which is then energized. The magnetron 16 is adjusted according to the signal changes, changing its energizing strength to regulate the emitted microwave power to the material in the reactor 22, thereby ensuring that the temperature of the material in the reactor 22 reaches the preset temperature. Figure 30 As shown in the figure, the preset temperature curve is a curve for efficient and environmentally friendly heating of sulfur anchoring grout, summarized from experience. The blue curve in the figure is the temperature rise curve of the grout under conventional heating recorded by thermocouples, and the purple curve is the curve that matches the temperature rise process of the blue curve. This figure aims to illustrate the temperature control principle and effect of the temperature control method. After the magnetron 16 is powered on, the output of microwave pulse power can be controlled by adjusting the duty cycle in the signal. The principle is based on the duty cycle characteristics within a pulse cycle, thereby realizing variable power transmission of microwaves within a pulse cycle.

[0126] See Figure 31 When the magnetron 16 emits microwaves, causing the temperature at the material measuring point to rise, without adjusting external factors, the PID output gradually decreases from oscillation and eventually reaches a constant state. The temperature inside the reactor 22 also stabilizes within the tolerance range (±1℃) of the preset target temperature. At this point, a consistent fit is achieved between the measured temperature at the measuring point and the preset target temperature curve, such as... Figure 32 As shown.

[0127] The formula for PID control is as follows:

[0128]

[0129] Where Y(t) is the output power; l(t) is the temperature difference; Kp is the proportional gain; T i Td is the integral time constant; Td is the differential time constant.

[0130] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0131] The above embodiments merely illustrate several implementation methods of the present invention, and their descriptions are relatively specific and detailed, but they should not be construed as limiting the scope of the invention patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of the present invention, and these all fall within the protection scope of the present invention. Therefore, the protection scope of this invention patent should be determined by the appended claims.
