[0016] 1. In the three-way orifice mixer high-efficiency double-liquid grouting machine, the first grouting pump and the second grouting pump use a 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 double-liquid slurry will be quickly injected into the rock for targeted grouting.

[0018] 3.

[0029] For example, see Figure 1-Figure 7 A three-way orifice mixer high-efficiency double-liquid grouting machine, comprising a fixed base 1, on which a plurality of groups of walking wheels 2 are installed, on which a first liquid storage tank 3 and a second liquid storage tank 4 are fixed, the first liquid storage tank 3 is connected to a first grouting pump 5, the first grouting pump 5 is connected to a first liquid outlet pipe 6, the second liquid storage tank 4 is connected to a second grouting pump 7, the second grouting pump 7 is connected to a second liquid outlet pipe 8, a three-way orifice mixer 9 is connected between the first liquid outlet pipe 6 and the second liquid outlet pipe 8, the three-way orifice mixer 9 is used to mix and discharge two liquids, a valve 10 is installed on the three-way orifice mixer 9, the other end of the three-way orifice mixer 9 is connected to a slurry outlet pipe 11, and a grouting head 12 is provided at the end of the slurry outlet pipe 11;

[0030] A pad 13 is fixed on the fixed base 1, and an adjustment component 14 is arranged 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 arranged on the positioning plate 141. A servo motor 143 is fixed on the surface of the positioning plate 141 and is connected to the screw rod 142 in a transmission manner. A slide 144 is threadedly connected on the circumference of the screw rod 142, and a first servo electric cylinder 145 is fixed on the slide 144. A positioning component 15 is fixed on 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 seat 151, the fixing seat 151 is fixedly connected to the output end of the first servo electric cylinder 145, a receiving groove 152 is provided inside the fixing seat 151, a second servo electric cylinder 153 is fixed in the receiving groove 152, a push plate 154 is connected to the output end of the second servo electric cylinder 153, a clamping ring 155 is fixed to the end of the push plate 154, and the clamping ring 155 is fixed to the outer surface of the grouting head 12;

[0032] In the technical scheme, 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 fixed seat 151 is pushed upward by the first servo electric cylinder 145, and the fixed seat 151 drives the grouting head 12 to move upward, so as to adjust the height of the grouting head 12. In summary, when the grouting head 12 is grouting to the grouting port, the horizontal position and height of the grouting head 12 can be adjusted first, so as to facilitate the alignment of the grouting head 12 with the grouting port, and facilitate the subsequent grouting work;

[0033] When grouting is performed, the push plate 154 is pushed to move by the second servo electric cylinder 153, and the push plate 154 drives the retaining ring 155 to move, and the retaining ring 155 drives the grouting head 12 to move, and 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, and the valve 10 is opened to draw out the slurry in the first liquid storage tank 3 and the second liquid storage tank 4, 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] Embodiment 2: 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 embodiment 1. For details, please refer to Figure 1-Figure 7 A through slot 16 is provided at the bottom of the push plate 154, a push block 17 is fixed at the output end of the second servo electric cylinder 153, the push block 17 is arranged in the through slot 16, 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 on the outer surface of the grouting head 12, an air pipe 21 is connected between the bottom of the air bag 20 and the clamp 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, a No. 1 spring 24 is provided inside the spring slot 23, a support sheet 25 slidably provided inside the spring slot 23 is fixed to the end of the clamping block 18, and two ends of the No. 1 spring 24 are respectively fixed between the top of the spring slot 23 and the support sheet 25;

[0036] A guide plate 26 is fixed to the outer surface of the fixing seat 151, a limit block 27 is fixed to the end of the guide plate 26, a first abutment block 28 is also arranged on the guide plate 26, a slide groove 29 for inserting the first abutment block 28 is provided at the bottom of the push plate 154, and the first abutment block 28 is inserted into the slide groove 29 to push the card block 18 out of the card groove 19;

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

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

[0039] In the present 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. After 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 is moved out of the card slot 19. At this time, the push plate 154 moves and contacts with the limit plate. Due to the limitation of the limit plate, the push plate 154 cannot move. The second servo electric cylinder 153 pushes the push block 17 to move forward and pushes the push block 17 out of the slot. The push block 17 drives the second resistance block 222 to slide in the moving slot 221, so that the second resistance block 222 resists the lifting rod 226, so that the lifting rod 226 drives the piston plate 224 upward to move. The second spring 225 stores force, and the piston plate 224 moves upward, and the gas inside the air cavity 223 is blown into the airbag 20 through the air pipe 21, so that the airbag 20 is expanded. The expanded airbag 20 can seal the grouting port to prevent leakage during grouting.

[0040] After grouting, 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 resistance 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 resistance block 28 slides out of the slide groove 29, the clamping block 18 loses the resistance of the first resistance 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 the grouting head 12 is moved out of the grouting port.

[0041] Embodiment 3: Since the three-way orifice mixer 9 is prone to shaking and poor stability when mixing the slurry, the service life of the interface is affected, and when the grouting head 12 is adjusted, the grouting pipe is driven to move, which is easy to cause wear of the grouting pipe. To address this problem, this embodiment is an improvement made on the basis of embodiment 2. 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, and 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, wherein the first protrusion 32 is fixed on the support platform 30, and the second protrusion 33 is fixed on the holder 31, and 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 grouting pipe, and a plurality of rollers 37 are rotatably provided inside the limit frame 36.

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

[0045] It should be noted that, in this article, relational terms such as first and second, etc. are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Moreover, the terms "include", "comprise" or any other variants thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, article or device.

[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. These improvements and modifications should also be regarded as the scope of protection of the present invention.
