Description

Technical Field

[0002] During tunnel construction, there is a demand for rapid grouting methods such as advanced curtain grouting, lightweight curtain grouting, and radial grouting, with dual-liquid grouting being the primary method. Currently, dual-liquid pumps on the market are piston pumps. Due to their structure, the dual-liquid slurry in the pipeline exhibits a non-mixed flow pattern, one in front of the other. This prevents efficient mixing of the dual-liquid slurry during pumping and injection into the rock, resulting in a failure to achieve rapid initial setting. Most dual-liquid grouting materials are flushed out by the water flow due to the inability to initially set, resulting in poor grouting results. Furthermore, dual-liquid grouting pumps on the market have low pressure, which can prevent the slurry from entering the rock. Summary of the Invention

[0016] In the three-way orifice mixer high-efficiency dual-liquid grouting machine, the first grouting pump and the second grouting pump adopt BW-320 mud pump to pump two slurries at the same time, and fully mix them through the three-way orifice mixer. After rapid mixing, the dual-liquid slurry will be quickly injected into the rock for targeted grouting, and the three-way orifice mixer contains balls inside, which can achieve full mixing of the dual-liquid slurry. At the same time, the dual-liquid slurry starts to react in the pipeline after mixing in the three-way orifice mixer, further reducing the reaction time. After the rock is slurried, it can achieve rapid initial setting, thereby improving the grouting effect. In addition, the three-way orifice mixer is connected by the first grouting pump and the second grouting pump at the same time, so that the grouting head pressure value is the sum of the pressures of the first grouting pump and the second grouting pump, thereby further improving the grouting pressure, thereby achieving high-efficiency and high-pressure injection.

Then, the push plate is pushed to move by the second servo electric cylinder, and the push plate drives the clamping ring to move, and the clamping ring drives the grouting head to move, so as to facilitate the insertion of the grouting head into the grouting port, saving time and effort.

[0018] 3. In the three-way orifice mixer high-efficiency dual-liquid grouting machine, when the grouting head is inserted into the grouting port, the push block is pushed by the second servo electric cylinder to move, and the push block drives the second resistance block to resist the lifting rod, so that the lifting rod drives the piston plate to move, and the gas inside the air cavity is blown into the air bag through the air pipe, so that the air bag is inflated and expanded. The grouting port is sealed by the expanded air bag, thereby improving the sealing of the grouting port, reducing the possibility of material leakage, and avoiding waste;

[0030] A pad 13 is fixed on the fixed base 1, and an adjustment component 14 is provided on the pad 13. The adjustment component 14 is used to adjust the height and horizontal position of the grouting head 12. The adjustment component 14 includes a positioning plate 141, and the positioning plate 141 is fixed on the top of the pad 13. A screw rod 142 is rotatably provided on the positioning plate 141. A servo motor 143 is fixed on the surface of the positioning plate 141 and is transmission-connected to the screw rod 142. A slide 144 is threadedly connected to the circumference of the screw rod 142. A first servo electric cylinder 145 is fixed on the slide 144. A positioning component 15 is fixed to the output end of the first servo electric cylinder 145. The positioning component 15 fixes the grouting head 12 to insert the grouting head 12 into the grouting port;

[0031] The positioning assembly 15 includes a fixing base 151, which is fixedly connected to the output end of the first servo electric cylinder 145. A receiving groove 152 is provided inside the fixing base 151, and a second servo electric cylinder 153 is fixed in the receiving groove 152. The output end of the second servo electric cylinder 153 is connected to a push plate 154, and a clamping ring 155 is fixed to the end of the push plate 154. The clamping ring 155 is fixed to the outer surface of the grouting head 12;

[0032] In the present technical solution, one kind of slurry is stored in the first liquid storage tank 3, and another kind of slurry is stored in the second liquid storage tank 4. Before grouting, the servo motor 143 drives the screw rod 142 to rotate, and the rotation of the screw rod 142 drives the slide 144 to move, and the movement of the slide 144 drives the first servo electric cylinder 145 to move, and the first servo electric cylinder 145 drives the fixed seat 151 to move horizontally, and the fixed seat 151 drives the grouting head 12 to move horizontally, and the horizontal position of the grouting head 12 is adjusted, and then the first servo electric cylinder 145 pushes the fixed seat 151 to move upward, and the fixed seat 151 drives the grouting head 12 to move upward, thereby adjusting the height of the grouting head 12. In summary, when the grouting head 12 is grouting toward the grouting port, the horizontal position and height of the grouting head 12 can be adjusted first, so that the grouting head 12 is aligned with the grouting port, which is convenient for subsequent grouting work.

[0033] During grouting, the push plate 154 is pushed to move by the second servo electric cylinder 153, the push plate 154 drives the retaining ring 155 to move, the retaining ring 155 drives the grouting head 12 to move, the grouting head 12 is inserted into the grouting port, and then the first grouting pump 5 and the second grouting pump 7 are started, the valve 10 is opened, the slurry in the first liquid storage tank 3 and the second liquid storage tank 4 is extracted, and the two slurries are mixed through the three-way orifice mixer 9. The three-way orifice mixer 9 contains balls for mixing, and the mixed slurry is injected into the grouting port through the grouting head 12.

[0034] In the second embodiment, when the grouting head 12 is inserted into the grouting port, the sealing performance between the grouting head 12 and the grouting port is poor, which may cause leakage and waste. To solve this problem, this embodiment is an improvement made on the basis of the first embodiment. For details, please refer to Figure 1-Figure 7 A through slot 16 is provided at the bottom of the push plate 154, and a push block 17 is fixed to the output end of the second servo electric cylinder 153. The push block 17 is arranged in the through slot 16, and a clamping block 18 is elastically provided on the push block 17. A clamping slot 19 is provided at the bottom of the through slot 16 for inserting the clamping block 18. An air bag 20 is fixed to the outer surface of the grouting head 12, and an air pipe 21 is connected between the bottom of the air bag 20 and the clamping ring 155. An air supply component 22 for supplying air to the air pipe 21 is provided in the push plate 154, and the air supply component 22 is elastically connected to the push block 17;

[0035] A spring slot 23 is provided inside the push block 17, and a No. 1 spring 24 is provided in the spring slot 23. A support piece 25 slidably provided inside the spring slot 23 is fixed to the end of the clamping block 18, and both ends of the No. 1 spring 24 are respectively fixed between the top of the spring slot 23 and the support piece 25;

[0036] A guide plate 26 is fixed to the outer surface of the fixing seat 151, and a limit block 27 is fixed to the end of the guide plate 26. A first resisting block 28 is also provided on the guide plate 26. A sliding groove 29 for inserting the first resisting block 28 is formed at the bottom of the push plate 154. The first resisting block 28 is inserted into the sliding groove 29 to push the clamping block 18 out of the clamping groove 19.

[0037] The width of the sliding groove 29 is smaller than the width of the clamping block 18 , and the top of the first abutting block 28 is kept level with the top of the clamping groove 19 ;

[0038] The air supply assembly 22 includes a movable groove 221 provided at the top of the through groove 16, a second interference block 222 slidably disposed in the movable groove 221 is fixed to the top of the push block 17, an air cavity 223 is provided in the push plate 154, one end of the air pipe 21 is connected to the air cavity 223, a piston plate 224 is provided in the air cavity 223, a second spring 225 is provided between the piston plate 224 and the top of the air cavity 223, and a lifting rod 226 for interfering with the second interference block 222 is fixed to the bottom of the piston plate 224;

[0039] In this technical solution, when the grouting head 12 needs to be inserted into the grouting port, the push block 17 is first pushed to move by the second servo electric cylinder 153. Since the clamping block 18 is clamped in the clamping groove 19, the push block 17 will drive the push plate 154 to move together, and the push plate 154 drives the clamping ring 155 to push the grouting head 12 into the grouting port. When the grouting head 12 is inserted into the grouting port for a certain length, the push block 17 drives the push plate 154 to move to the limit plate, so that the limit plate restricts the push plate 154, and the push plate 154 cannot continue to move. Before the push plate 154 moves to the limit plate, the first resistance block 28 is inserted into the slide groove 29. When the first resistance block 28 slides along the slide groove 29, the first resistance block 28 resists the clamping block 18, causing the clamping block 18 to move upward, and the No. 1 spring 24 is compressed and stored force is accumulated until the card block 18 moves out of the card slot 19. At this time, the push plate 154 moves and contacts the limit plate. Due to the restriction of the limit plate, the push plate 154 cannot move. The second servo electric cylinder 153 pushes the push block 17 forward and pushes the push block 17 out of the slot. The push block 17 drives the second contact block 222 to slide in the moving slot 221, so that the second contact block 222 contacts the lifting rod 226, so that the lifting rod 226 drives the piston plate 224 upward to move. The No. 2 spring 225 stores force, and the piston plate 224 moves upward, blowing the gas inside the air cavity 223 into the air bag 20 through the air pipe 21, so that the air bag 20 is inflated. The inflated air bag 20 can seal the grouting port to prevent leakage during grouting.

[0040] After grouting is completed, the second servo cylinder 153 is reset, first pulling the push block 17 to reset, the lifting rod 226 loses the resistance of the second contact block 222, the No. 2 spring 225 unloads the force, so that the piston plate 224 drives the lifting rod 226 to reset, and then the first contact block 28 slides out of the slide groove 29, the clamping block 18 loses the resistance of the first contact block 28, the No. 1 spring 24 unloads the force, and the clamping block 18 is inserted into the clamping groove 19 again, and then the push block 17 can drive the push plate 154 to move together, and move the grouting head 12 out of the grouting port.

[0041] In the third embodiment, the three-way orifice mixer 9 is prone to shaking when mixing the slurry, which has poor stability and affects the service life of the interface. In addition, when the grouting head 12 is adjusted, the grouting pipe is driven to move, which easily causes wear of the grouting pipe. To address this problem, this embodiment is an improvement made on the basis of the second embodiment. For details, please refer to Figure 1-Figure 7 A support platform 30 is fixed on the fixed base 1, and a clamping seat 31 is connected to the top of the support platform 30 through a fixing component. The clamping seat 31 clamps the three-way orifice mixer 9 on the support platform 30;

[0042] The fixing assembly includes a first protrusion 32 and a second protrusion 33. The first protrusion 32 is fixed to the support platform 30, and the second protrusion 33 is fixed to the base 31. The first protrusion 32 and the second protrusion 33 are fixedly connected by a fastening bolt 34 and a nut 35.

[0043] The fixing seat 151 is provided with a limit frame 36 for limiting the pulp outlet pipe 11. The limit frame 36 is provided with a plurality of rollers 37 for rotation inside.

[0044] In the present technical solution, a limit frame 36 is provided so that when the position of the grouting head 12 is adjusted, the grouting pipe can slide in the limit frame 36, and a roller 37 is provided in the limit frame 36, so that the grouting pipe slides more smoothly, thereby increasing the protection of the grouting pipe and reducing wear. At the same time, the support platform 30 is provided to fix the position of the three-way orifice mixer 9, thereby increasing the stability of the slurry when flowing through the three-way orifice mixer 9, and preventing the three-way orifice mixer 9 from shaking at will, thereby affecting the internal slurry mixing, and the use effect is good.

[0046] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the technical principles of the present invention.
