Description

Technical Field

[0001] This invention belongs to the field of tunnel grouting technology, specifically a mixed two-component grouting device with self-rotating anchoring and dual self-cleaning functions. Background Technology

[0002] In underground engineering construction, two-component grouting technology is widely used for surrounding rock reinforcement, crack sealing, and water stoppage and seepage prevention. The core of this technology is to precisely mix two types of grout according to the design ratio and then inject them stably into the construction area through a grouting gun. Compared with traditional grouting guns, the mixed two-component grouting equipment can accurately control the grout temperature and ensure that the grout is injected at the optimal viscosity, thereby ensuring the quality of the project. The grouting equipment mainly consists of two parts: the gun head and the ground pump truck. The gun head is responsible for accurately injecting the grout into the target area, while the pump truck is responsible for the supply and pressure control of the grout. For the pump truck, special attention should be paid to its stability and pumping capacity to ensure that the grout can be supplied to the construction area evenly and continuously, and to maintain efficient operation in complex underground environments.

[0003] The prior art document, CN102896053B, discloses a grouting spray gun for a non-cleaning pneumatic dual-liquid grouting pump. It includes a valve housing, an air inlet connector at the top of the valve housing that connects to the air outlet of the pneumatic pump assembly, a discharge connector at the front end of the valve housing, and an inlet connector at the rear end of the valve housing. The valve housing contains an adjustment mechanism for controlling material flow and airflow blockage, and an operating handle for controlling the adjustment mechanism is located outside the valve housing. This device features an advanced, reasonable, compact, and simple design; it is small in size and light in weight. It incorporates multiple one-way check valves to ensure proper mixing quality. No other chemical liquids are needed to clean the spray gun. After grouting, opening the cleaning air source ball valve and rotating the operating handle 180 degrees will automatically clean the gun for approximately two minutes without clogging.

[0004] During actual grouting, the aforementioned device may cause the injected grout to generate a backlash force due to crack changes, which could lead to the overturning of the surface pump truck. In underground engineering construction, the required grouting volume is large and the time is long. Therefore, it is usually necessary to use hydraulic support legs, ground anchors, or expansion bolts to firmly connect the vehicle body to the ground or tunnel wall, turning it into a stable grouting platform to disperse the backlash force of the grout injection. However, using hydraulic support legs cannot guarantee the vehicle body's grip, which can easily lead to equipment displacement or overturning. Using ground anchors or expansion bolts for anchoring often requires manual operation, which is time-consuming and labor-intensive, affecting the working efficiency of the equipment. Summary of the Invention

[0005] The purpose of this invention is to provide a mixed two-component grouting device with self-rotating anchoring and dual self-cleaning functions to prevent the equipment from tilting or overturning under grouting back thrust, thereby solving the problems mentioned in the background art.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a mixed two-component grouting device with self-rotating anchoring and dual self-cleaning functions, comprising a shell, a frame fixedly connected to the bottom of the shell, a drive component mounted on the bottom of the frame, a grouting pump fixedly connected to the side wall of the shell, a grouting pump with a pumping pipe fixedly connected to its end, and the pumping pipe being connected to a nozzle via a dynamic mixer, further comprising:

[0007] A positioning mechanism, wherein the positioning mechanism is located in the middle of the vehicle frame;

[0008] A reciprocating impurity removal mechanism, wherein the reciprocating impurity removal mechanism is connected to a positioning mechanism;

[0009] The positioning mechanism includes a protective shell fixed to the middle of the frame, with its bottom open to the outside. A pair of lifting columns are slidably connected to the middle of the protective shell via a fixing plate. Each lifting column has an arc-shaped sleeve plate fixed to its bottom. Diagonal rods are rotatably sleeved on both sides of the two arc-shaped sleeve plates. The two pairs of diagonal rods are arranged in an outward V-shape on both the longitudinal and transverse sides. Through the positioning mechanism and the reciprocating impurity removal mechanism, a stable anchoring effect and a self-cleaning function are achieved. This not only improves the working efficiency of the equipment and reduces the amount of maintenance work, but also ensures that the equipment can maintain optimal performance after long-term operation, reducing the risk of failure caused by impurity accumulation. This greatly reduces the overall operating and maintenance costs. The two pairs of outward V-shaped diagonal rods are arranged so that each diagonal rod is tilted at a certain angle to the ground, improving the drilling accuracy of the diagonal rods.

[0010] Preferably, the positioning mechanism further includes a cylinder fixed to the top of the vehicle frame, the output end of the cylinder being fixed to a top plate, one side of the top plate being fixed to the top of a pair of lifting columns, and the other side of the top plate being fixed to a pair of triangular plates.

[0011] Preferably, the outer walls of the pair of triangular plates are slidably abutted against the inner cavity of the protective shell, and the inclined ends of the triangular plates are provided with inclined grooves.

[0012] Preferably, each of the pair of arc-shaped sleeve plates is slidably connected to a push-pull rod at the middle, and the push-pull rod passes through the end of the lifting column. The top of each push-pull rod is movably connected to the inclined slide groove via a ball joint.

[0013] Preferably, the inner cavity of one side of the inclined rod is provided with a spiral groove, and the lower end of the pair of push-pull rods is fixed with an arc-shaped protrusion. The push-pull rods are slidably connected to the spiral groove through the arc-shaped protrusion.

[0014] Preferably, the inclined rods on both sides are respectively fixed with a main bevel gear and a secondary bevel gear, and the two mesh with each other. The ends of the inclined rods are all fixed with drill bits. When the lifting column moves down, it drives the inclined rod to move downward. When the triangular plate moves downward, the push-pull rod presses into the inner cavity of the inclined rod. The arc-shaped protrusion interacts with the spiral groove to apply radial pressure to the inclined rod, causing it to rotate. In conjunction with the main bevel gear driving the secondary bevel gear to rotate, the inclined rod can rotate while moving downward, thereby increasing the grip of the equipment and effectively improving the frame's ability to resist the grouting back thrust.

[0015] Preferably, the reciprocating impurity removal mechanism includes a guide rod fixed to the middle of a pair of fixed plates, a vertical plate slidably sleeved on the outer wall of the guide rod, a horizontal plate fixed to the lower end of the vertical plate, and a cross-shaped groove opened in the middle cavity of the frame, with the vertical plate and the horizontal plate slidably connected in the cross-shaped groove.

[0016] Preferably, the upper ends of the vertical plate are provided with wave grooves on both sides, the bottom of the top plate is fixedly connected to a double plate, the lower inner sides of the double plates are fixedly connected to a sliding column, and the outer wall of the sliding column is slidably connected to the wave groove.

[0017] Preferably, an I-shaped rod is fixedly connected to the bottom of the vertical plate, and a clamping plate is fixedly connected to each of the four corners of the I-shaped rod, with a brush fixedly connected to the bottom of each clamping plate.

[0018] Preferably, the bottom of the frame has four grooves, and the upper end of the card plate is slidably connected to the grooves. Since the lower end of the vertical plate slides inside the frame and the upper end is limited by the guide rod, the downward movement of the sliding column will continuously squeeze the wave groove, forming radial pressure, pushing the vertical plate to move back and forth a short distance, thereby generating vibration, which in turn causes the brush to vibrate. The inclined rod rotates during the reset process and can clean the surface impurities when it comes into contact with the brush. In addition, the impurities on the brush can also be shaken off in time due to the vibration.

[0019] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0020] This invention utilizes a combination of structures such as inclined rods, triangular plates, and push-pull rods. The inclined rods not only move downwards vertically but also rotate during this downward movement. This dual action effectively enhances the drilling capability into the ground, enabling efficient drilling under various geological conditions and demonstrating strong adaptability. Furthermore, because each pair of inclined rods is arranged in an outward V-shape and maintains a certain angle with the bottom surface, the rotation of the inclined rods allows for precise control of the drill bit's advance direction, avoiding potential errors and deviations. The V-shaped structure can distribute the load evenly, bearing the overall weight of the frame and improving the stability and anchoring effect of the equipment, preventing tilting or overturning caused by grouting back thrust.

[0021] This invention utilizes a combination of structures including double plates, vertical plates, corrugated grooves, and I-beams. The inclined rod continuously rotates during its retraction and repositioning. When the inclined rod contacts the brush surface, it effectively removes dirt and impurities adhering to the inclined rod, significantly reducing mechanical jamming or wear caused by impurity accumulation. Simultaneously, the reciprocating vibration of the brush not only helps clean the inclined rod but also promptly shakes off impurities adhering to the brush. This prevents the brush from losing its cleaning effect due to impurity accumulation, ensuring the continuity and efficiency of the cleaning process and avoiding incomplete cleaning. Therefore, the dual self-cleaning function of the inclined rod and brush not only improves the equipment's working efficiency and reduces maintenance costs but also ensures stable operation and a longer service life.

[0036] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0037] like Figures 1 to 12 As shown, the present invention provides a mixed two-component grouting device with self-rotating anchoring and dual self-cleaning functions, including a housing 100, a frame 200 fixedly connected to the bottom of the housing 100, a drive unit 300 mounted on the bottom of the frame 200, a grouting pump 400 fixedly connected to the side wall of the housing 100, a grouting pipe 500 fixedly connected to the end of the grouting pump 400, and the grouting pipe 500 connected to a gun head via a dynamic mixer, and further including:

[0038] Positioning mechanism 600, which is located in the middle of frame 200;

[0039] A reciprocating cleaning mechanism 700 is connected to a positioning mechanism 600;

[0040] The positioning mechanism 600 includes a protective shell 610 fixed to the middle of the frame 200, and the bottom of the protective shell 610 is open to the outside. A pair of lifting columns 630 are slidably connected to the middle of the protective shell 610 through a fixing plate 620. The bottom of each lifting column 630 is fixed with an arc sleeve plate 660. Both sides of the two arc sleeve plates 660 are rotatably sleeved with diagonal rods 670. The two pairs of diagonal rods 670 are arranged in an outward V-shape on both the longitudinal and transverse sides.

[0041] The above scheme employs a system where a pair of grouting pumps 400 are connected to a common nozzle via a pipeline. The grout is mixed within the nozzle and then injected into the crack. Because higher ambient temperatures decrease grout viscosity, a heating wire is wrapped around the nozzle for heating and insulation, thus reducing grout viscosity and resistance. The nozzle-mixing grout device is a dynamic mixer, which adds a driving source. Compared to traditional static mixers, this effectively reduces resistance, simplifying the complex mixing mechanism. Therefore, under ideal conditions, the grouting resistance for high-viscosity two-component grout can be significantly reduced to only 0.5 to 1 MPa. This is a significant reduction compared to traditional static mixing guns (which require grouting pressures above 10 MPa), eliminating the need for ultra-high-pressure grouting pumps and saving energy. The driving component 300 mainly includes a driving source for the chassis 200, wheels, and linkage bearings, used to drive the chassis 200 to move and stopping once the designated grouting position is reached. The chassis 200 serves as the foundation of the entire equipment, with the drive unit 300 mounted at its bottom to provide power support. It also secures the grouting pump 400 and the grouting pipe 500, ensuring the supply and flow of grout. The positioning mechanism 600 in the middle of the chassis 200 is tightly connected to the other parts of the equipment via a protective shell 610 and a lifting column 630. The positioning mechanism 600 ensures the stability of the equipment during operation, preventing displacement or overturning due to reaction forces. The cooperation of the arc-shaped sleeve plate 660 and the diagonal rod 670 of the lifting column 630 enables precise positioning and ground drilling. The two diagonal rods 670 are located on the longitudinal and transverse sides, arranged in an outward V-shape. Through rotation and downward pressing, they penetrate deep into the ground, effectively enhancing the chassis 200's grip and resisting grouting reaction forces. The reciprocating cleaning mechanism 700 is linked to the positioning mechanism 600, ensuring the cleaning of impurities from the surface of the diagonal rods 670 during equipment operation, further guaranteeing the equipment's ability to operate stably for extended periods. The coordinated operation of the two sets of mechanisms effectively improves the performance of the grouting gun in complex underground environments.

[0042] like Figure 5 , Figure 6 and Figure 12 As shown, the positioning mechanism 600 also includes a cylinder 690 fixed to the top of the frame 200. The output end of the cylinder 690 is fixed to a top plate 680. One side of the top plate 680 is fixed to the top of a pair of lifting columns 630, and the other side of the top plate 680 is fixed to a pair of triangular plates 640. The outer walls of the pair of triangular plates 640 slide against the inner cavity of the protective shell 610. The inclined ends of the triangular plates 640 are provided with inclined grooves 6150. The middle of the pair of arc sleeve plates 660 is slidably connected to push-pull rods 650, and the push-pull rods 650 pass through the ends of the lifting columns 630. The tops of the push-pull rods 650 are movably connected to the inclined grooves 6150 through ball joints 6160.

[0043] like Figure 5 and Figure 6As shown, the inner cavity of one side of the inclined rod 670 is provided with a spiral groove 6130, and the lower end of a pair of push-pull rods 650 is fixed with an arc-shaped protrusion 6140. The push-pull rods 650 are slidably connected to the spiral groove 6130 through the arc-shaped protrusion 6140. The two sides of the inclined rod 670 are respectively fixed with a main bevel gear 6110 and a secondary bevel gear 6100, and the two mesh with each other. The ends of the inclined rods 670 are fixed with a drill bit 6120.

[0044] The above scheme employs a method where the push-pull rod 650 slides axially through a guide groove in the middle of the arc-shaped sleeve plate 660, preventing it from rotating. This facilitates the radial pressure exerted by the arc-shaped protrusion 6140 during its movement, which drives the diagonal rod 670 to rotate. After the frame 200 reaches the designated grouting position, the cylinder 690 moves the top plate 680 downwards, causing the lifting columns 630 and triangular plates 640 on both sides of the top plate 680 to move downwards simultaneously. As the lifting columns 630 move downwards, they drive the diagonal rod 670 downwards. As the triangular plates 640 move downwards, the push-pull rod 650 presses into the inner cavity of the diagonal rod 670. The arc-shaped protrusion 6140 interacts with the spiral groove 6130, applying radial pressure to the diagonal rod 670 and causing it to rotate. This, combined with the main bevel gear 6110 driving the secondary bevel gear 6100 to rotate, allows the diagonal rod 670 to rotate simultaneously with its downward movement. Two pairs of V-shaped diagonal braces 670 are installed, each diagonal brace 670 is inclined at a certain angle to the ground, driving the drill bit 6120 to drill into the ground. The lower end of the diagonal brace 670 penetrates deep into the ground, further increasing the equipment's grip and effectively improving the chassis 200's ability to resist grouting back thrust.

[0045] like Figures 7 to 11 As shown, the reciprocating impurity removal mechanism 700 includes a guide rod 790 fixed to the middle of a pair of fixed plates 620. A vertical plate 740 is slidably sleeved on the outer wall of the guide rod 790. A horizontal plate 750 is fixed to the lower end of the vertical plate 740. A cross-shaped groove is opened in the middle cavity of the frame 200. The vertical plate 740 and the horizontal plate 750 are slidably connected in the cross-shaped groove. Wave grooves 760 are opened on both sides of the upper end of the vertical plate 740. The bottom of the top plate 680 Double plates 770 are fixedly connected, and sliding columns 780 are fixedly connected to the inner side of the lower end of each double plate 770. The outer wall of the sliding column 780 is slidably connected to the wave groove 760. An I-shaped rod 730 is fixedly connected to the bottom of the vertical plate 740. A clamping plate 710 is fixedly connected to each of the four corners of the I-shaped rod 730. A brush 720 is fixedly connected to the bottom of each clamping plate 710. Four grooves are opened at the bottom of the frame 200, and the upper end of each clamping plate 710 is slidably connected to the groove.

[0046] The above scheme involves the top plate 680 driving the double plates 770 downwards, causing the fixed plate 620 to exert pressure and thus pushing the sliding column 780 downwards. Since the lower end of the vertical plate 740 slides within the frame 200, and its upper end is limited by the guide rod 790, the downward movement of the sliding column 780 continuously compresses the wave groove 760, creating radial pressure. This pressure pushes the vertical plate 740 to perform short-distance reciprocating translation, generating vibration, which ultimately causes the brush 720 to vibrate. During the reset process, the inclined rod 670 rotates, contacting the brush 720 to clean surface impurities. Furthermore, impurities on the brush 720 are shaken off by the vibration, preventing them from hardening due to long-term accumulation and affecting future use. This dual self-cleaning effect of the drill bit 6120 and the brush 720 not only ensures the continuous and efficient operation of the equipment but also improves the overall stability and reliability of the operation. Through stable anchoring and self-cleaning functions, the equipment not only improves its working efficiency and reduces maintenance workload, but also ensures that the equipment can maintain optimal performance after long-term operation, reducing the risk of failure caused by the accumulation of impurities, thereby greatly reducing overall operating and maintenance costs.

[0047] Working principle and usage process of this invention:

[0048] First, during grouting operations in underground engineering, driven by the pressure of the grouting pump 400, a pair of grouting pipes 500 respectively enter different grouts from their lower ports and exit from their upper ports. After thorough mixing in a static mixer, the uniformly mixed grout is ejected at high speed from the nozzle and injected into the ground fissures. According to Newton's third law, the moment the grout is ejected forward, it will generate a reaction force equal in magnitude and opposite in direction on the grouting gun itself. That is, the entire frame 200 will be subjected to a counter-thrust force. Therefore, the frame 200 needs to be anchored in place before grouting can begin. When the frame 200 reaches the designated grouting position, the drive unit 300 stops driving, and the control system activates the cylinder 690. The cylinder 690 drives the top plate 680 to move downward, thereby causing the pair of lifting columns 630 and the pair of triangular plates 640 fixed to both sides of the top plate 680 to move downward, and the fixed double plates 770 also move downward simultaneously.

[0049] Furthermore, when the lifting column 630 moves downward, it drives a pair of arc-shaped sleeve plates 660 to move downward simultaneously, causing the inclined rods 670 on both sides to also move downward and closer to the ground. At this time, the downward movement of the triangular plate 640 can push the push-pull rod 650 into the inner cavity of the inclined rod 670. At this time, the arc-shaped protrusion 6140 continuously presses against the spiral groove 6130, applying radial pressure to the inclined rod 670, thereby causing the inclined rod 670 to rotate. Then, the main bevel gear 6110 fixed at the end drives the secondary bevel gear 6100 to rotate, thereby causing the inclined rod 670 on the other side to also rotate, realizing that the inclined rod 670 moves downward and also rotates. Since each pair of diagonal rods 670 is set in an outward V-shape on both the longitudinal and transverse sides, each diagonal rod 670 rotates and advances at a certain angle to the ground. In conjunction with the drill bit 6120, the ground is drilled open, and the lower end of the diagonal rod 670 can be screwed into the ground, ultimately making the drive unit 300 suspended from the ground. The two pairs of V-shaped diagonal rods 670 support the overall weight of the frame 200, and the ends of the diagonal rods 670 are inserted into the ground at an angle, which improves the grip effect and effectively increases the performance of the frame 200 in resisting the grouting reaction force.

[0050] During reset, the starting cylinder 690 pushes the top plate 680 upward, thereby simultaneously moving the lifting column 630, the triangular plate 640, and the double plate 770 upward. The lifting column 630 drives the arc sleeve plate 660 and the diagonal bar 670 upward simultaneously, causing the drive component 300 to change from a suspended state to contact the ground, supporting the overall weight of the frame 200. At the same time, the triangular plate 640 pulls the push-pull rod 650 through the ball bearing 6160 to slide out of the diagonal bar 670, and the arc-shaped protrusion 6140 squeezes the spiral groove 6130, thereby causing the diagonal bar 670 to rotate in the opposite direction, allowing the diagonal bar 670 to be easily pulled out of the ground and retracted to the bottom area of ​​the frame 200.

[0051] Finally, whenever the top plate 680 moves downward, it drives the double plates 770 downward, and the sliding column 780 fixed to the inner side of the double plates 770 also moves downward synchronously. Since the lower end of the vertical plate 740 can slide within the frame 200 through the horizontal plate 750, and the upper end is slidably sleeved within the guide rod 790 for limiting and guiding, the sliding column 780 continuously squeezes the wave groove 760 during its downward movement. Because the sliding column 780 always moves downward in a straight line, the radial pressure generated by squeezing the wave groove 760 can push the vertical plate 740 to move back and forth a short distance. The rapid movement generates vibration, and the reciprocating interval set by the wave groove 760 serves as the amplitude, which can be set according to requirements. The vertical plate 740 drives the bottom I-shaped rod 730 to vibrate synchronously, which in turn drives the clamping plate 710 to move back and forth in the groove, and finally causes the brush 720 to move back and forth, generating vibration and shaking off the impurities remaining on the surface. Therefore, when the inclined rod 670 returns to its original position, the double plate 770 moves upward and resets. The sliding column 780 presses against the fixed plate 620, causing the vertical plate 740 to move back and forth again. This, in turn, drives the I-shaped rod 730 to move back and forth, further driving the clamping plate 710 to slide back and forth within the groove. Finally, the brush 720 moves back and forth, brushing away impurities from the surface of the inclined rod 670 and shaking them off. On one hand, the inclined rod 670 constantly rotates and contacts the surface of the brush 720, removing dirt and other impurities. On the other hand, the reciprocating vibration of the brush 720 promptly shakes off impurities adhering to it, preventing the dirt from hardening and hardening, which would affect future use. This achieves a dual self-cleaning effect on both the drill bit 6120 and the brush 720.
