Description

Technical Field

[0001] This invention relates to the field of grouting device technology, specifically a grouting device for repairing cracks in a main wall surface. Background Technology

[0002] When reinforcing building structures or repairing geological engineering, crack treatment is a crucial step, and grouting technology is one of the effective methods to solve this problem. Grouting technology injects specific repair materials into cracks to achieve the purpose of filling, sealing, and reinforcing. The key equipment for this technology is the grouting device, whose performance directly affects the efficiency of grouting operations and the quality of repairs. However, there are still several problems in the existing grouting equipment technology, which limit the application effect and safety of grouting technology.

[0003] Firstly, in existing grouting equipment, the mixing paddle is used to mix the grouting material to ensure its uniformity. However, after prolonged use, hardened material residue will adhere to the surface of the mixing paddle. This not only makes cleaning difficult, but also affects the mixing efficiency and material quality during the next use if it is not cleaned properly. Currently, the mixing paddle in the equipment is difficult to disassemble, which makes cleaning cumbersome. In addition, depending on different project needs, it may be necessary to replace the mixing paddle with one of different shapes or sizes. The replacement process in the existing design is cumbersome and reduces work efficiency.

[0004] Secondly, the mixing effect is directly related to the quality of the grouting material. However, most of the existing grouting equipment uses a unidirectional rotating mixing paddle, which leads to the formation of stratification and air bubbles in the mixed material, affecting the grouting effect and the quality of structural repair.

[0005] Furthermore, existing equipment lacks effective safety protection measures during operation, and operators may suffer personal injury accidents due to sudden equipment start-up or misoperation. At the same time, the stability and reliability of the equipment during operation are also important factors in ensuring operational safety, and this aspect needs to be improved in the current technology.

[0006] In summary, existing grouting devices have significant shortcomings in terms of the ease of cleaning the mixing blade, mixing efficiency and effect, and equipment safety. These problems not only affect the quality and efficiency of repair work but also pose potential risks to the safety of operators. Therefore, there is an urgent need to develop a new type of grouting device that can easily and quickly clean and replace the mixing blade, provide superior mixing effects, and has advanced safety protection measures to meet the needs of modern building reinforcement and geological engineering repair. Summary of the Invention

[0007] In view of the above-mentioned shortcomings in the existing technology, the purpose of the present invention is to provide a grouting device that is easy to clean the stirring paddle, has excellent stirring effect, and is highly safe.

[0008] The technical solution adopted by the present invention to achieve the above objectives is: a grouting device for repairing cracks in the main wall surface, comprising a grouting device and a grouting gun, wherein the grouting device comprises a machine base;

[0009] The preparation tank is fixedly connected to the machine base of the device. A stirring shaft is rotatably connected to the bottom of the preparation tank. A tank cover is provided on the top of the preparation tank. A stirring paddle is inserted into the stirring shaft. The top of the stirring paddle abuts against the bottom of the tank cover.

[0010] And a locking mechanism fixedly connected to the machine base of the device, the locking mechanism being used to lock the can lid to the preparation can;

[0011] The pump body and the power motor are fixedly connected to the machine base of the device, and the power motor is connected to the stirring shaft and the pump body in a power-transmitting manner.

[0012] The pump body is connected to the preparation tank via a first pipe, and the pump body is connected to the grouting gun via a second pipe.

[0013] In the above technical solution, the stirring shaft is fixedly connected to the insertion limiting block in the area inside the preparation tank. The bottom end of the stirring paddle shaft is provided with an insertion hole. The inner wall of the insertion hole is provided with a limiting groove that matches the insertion limiting block. The stirring shaft passes through the insertion hole, and the insertion limiting block is fitted into the limiting groove.

[0014] A rotating platform is fixedly connected to the bottom of the tank lid. A rotating groove is provided on the rotating platform. A rotating disk is fixedly connected to the top of the shaft of the stirring paddle. The rotating disk is fitted into the rotating groove.

[0015] In the above technical solution, the locking mechanism includes a fixed locking platform, a movable locking platform, and a traction component. The fixed locking platform is fixedly connected to the outer wall of the preparation tank. The fixed locking platform is provided with a locking socket. The fixed locking platform is provided with a first locking hole through the locking socket. The movable locking platform is fixedly connected to the tank cover to match the fixed locking platform. The movable locking platform is provided with a second locking hole. The movable locking platform is fitted into the locking socket, and the first locking hole corresponds to the second locking hole.

[0016] The device is equipped with a traction component on its machine base, and a locking rod is provided on the traction component. The traction component can pull the locking rod through or out of the first locking hole and the second locking hole.

[0017] In the above technical solution, the traction component includes a sliding column, a lead screw, a traction platform, a first worm, and a first worm wheel. The sliding column is fixedly connected to the fixed locking platform on the device base. The traction platform is slidably connected to the sliding column. The lead screw is threadedly connected to the traction platform. One end of the lead screw is fixedly connected to an operating shaft. The operating shaft is rotatably connected to the device base.

The first worm meshes with the first worm wheel. An operating turntable is fixedly connected to the first worm. The locking rod is fixedly connected to the traction platform.

[0018] In the above technical solution, a power supply platform is provided on the preparation tank corresponding to the fixed locking platform. A push-button power switch is fixedly connected to the power supply platform, and the power switch is located on the power supply line of the power motor. A main switch is also provided on the power supply line. The power switch corresponds to the first locking hole. When the traction component drives the locking rod through the first locking hole and the second locking hole and presses down the power switch, the circuit is connected. When the locking rod does not press down on the power switch, the circuit is disconnected.

[0019] In the above technical solution, the power motor is connected to the stirring shaft through a first transmission assembly, and the power motor is connected to the pump body through a second transmission assembly. The second transmission assembly is provided with a ratchet assembly. Under the action of the ratchet assembly, when the power motor rotates in the forward direction, the pump body does not work, and when the power motor rotates in the reverse direction, the pump body works.

[0020] In the above technical solution, the first transmission component includes a first gear, a second gear, a reversing gear, a first sector gear, and a second sector gear. The first gear is fixedly connected to the stirring shaft at the bottom of the preparation tank, and the second gear is fixedly connected to the bottom of the first gear. The reversing gear is rotatably connected to the bottom surface of the preparation tank and meshes with the first gear. A drive shaft is rotatably connected to the bottom of the preparation tank, and the first sector gear is fixedly connected to the drive shaft corresponding to the reversing gear. The first sector gear can mesh with the reversing gear by rotation. The second sector gear is fixedly connected to the drive shaft at the bottom of the first sector gear and meshes with the second gear by rotation. The toothed surfaces of the first sector gear and the second sector gear have different orientations.

[0021] When the first sector gear just disengages from the reversing gear, the second sector gear does not mesh with the second gear; when the second sector gear just disengages from the second gear, the first sector gear does not mesh with the reversing gear.

[0022] A second worm gear is fixedly connected to the drive shaft at the bottom of the second sector gear. An input shaft is rotatably connected to the device base to match the second worm gear. A second worm is provided on the input shaft, and the second worm meshes with the second worm gear.

[0023] The power output shaft of the power motor is connected to the input shaft through a first power transmission component.

[0024] In the above technical solution, the second transmission component further includes an output shaft, a second power transmission component, and a pump shaft. The power input end of the pump body is fixedly connected to the pump shaft, and the input shaft is fixedly connected to the power output shaft. The input shaft is provided with the ratchet assembly. The input shaft and the pump shaft are connected by the second power transmission component, and the second power transmission component is located on the power output end side of the ratchet assembly.

[0025] In the above technical solution, the device includes a base, a mounting frame, and a set of brake wheels. Multiple sets of brake wheels are fixedly connected to the bottom surface of the base. The mounting frame is fixedly connected to the base. The traction component is located on the mounting frame. A push handle and a suspension frame are also fixedly connected to the base.

[0026] In the above technical solution, a handle is fixedly connected to the can lid, and a feeding port is also fixedly connected to the can lid, with a transparent sealing cover plate embedded inside the feeding port.

[0027] The beneficial effects of this invention are:

[0028] 1. The stirring paddle is inserted into the stirring shaft at the bottom, and its top is rotatably connected to the tank cover. When the stirring shaft is rotated by the drive motor, the stirring paddle stirs the raw materials in the preparation tank. This structure makes it easy to clean and replace the stirring paddle, avoids excessive impurities adhering to the surface of the stirring paddle, and ensures the stirring effect.

[0029] 2. After the lid is installed on the upper part of the preparation tank, the locking rod can be moved by the traction component, so that the locking rod can be inserted into the locking hole, thus making the lid unable to be removed. This structure can avoid personnel injury due to misoperation during the operation of the device, and has high safety.

[0030] 3. The preparation tank is also equipped with a power switch. When the operating turntable is rotated to make the worm gear drive the worm wheel to rotate, the lead screw can be rotated, which in turn causes the traction table to drive the locking rod through the locking hole and press down the power switch. At this time, the power motor can be started through the main switch. When the locking rod cannot press down the power switch, the circuit is broken, which also makes the power motor stop working. This structure can better avoid personnel misoperation and enhance safety. At the same time, the self-locking effect of the first worm and the first worm wheel can prevent the locking rod from being displaced due to vibration, which would cause the circuit to be broken when the device is working and affect the normal operation.

[0031] 4. The power motor provides power to the stirring shaft through the first transmission assembly and to the pump body through the second transmission assembly. The second transmission assembly is equipped with a ratchet assembly, which means that when the power motor rotates in the forward direction, the pump body does not work, thus preventing the pump body from pumping the slurry in the preparation tank to the grouting gun. When the power motor rotates in the reverse direction, the pump body works, allowing it to pump the slurry in the preparation tank to the grouting gun for grouting. The stirring shaft can drive the stirring paddle to stir the raw materials in the preparation tank in both forward and reverse directions. When the motor rotates in the forward direction, the stirring paddle works to ensure uniform stirring of the raw materials. When the motor rotates in the reverse direction, the stirring paddle works to prevent sedimentation of the stirred slurry. This design is reasonable, has excellent performance, and reduces the number of motors, thus reducing the failure rate.

[0032] 5. When the power motor drives the stirring shaft to rotate, the power motor can first drive the drive shaft to rotate. In this way, the second sector gear meshes with the second gear, causing the stirring shaft to rotate, which in turn causes the internal stirring paddle to rotate. After the drive shaft rotates a certain angle, the second sector gear disengages from the second gear. At this time, the first sector gear drives the reversing gear to rotate, and then the reversing gear drives the first gear to rotate. At this time, the stirring shaft also rotates, but in the opposite direction to the first rotation. This cycle continues, so that the stirring shaft drives the stirring paddle to stir the raw materials in both directions without changing the rotation direction of the drive shaft, ensuring excellent stirring effect of the raw materials.

[0054] 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.

[0055] Please see Figure 1 —10, a grouting device for repairing cracks in a main wall surface, including a grouting device and a grouting gun 900. The grouting device includes a device base 100, a preparation tank 200, and a locking mechanism 300. The device base 100 includes a base 101, a mounting frame 102, and a brake wheel assembly 103. Multiple brake wheel assemblies 103 are fixedly connected to the bottom surface of the base 101. The mounting frame 102 is fixedly connected to the base 101. A push handle 209104 and a suspension frame 105 are also fixedly connected to the base 101. The base 101 can be moved by pushing the handle 209104, which facilitates the transfer of the device. The suspension frame 105 is used to suspend the grouting gun 900 and its connected pipes.

[0056] The preparation tank 200 is fixedly connected to the machine base 101, and a stirring shaft 201 is rotatably connected to the bottom of the preparation tank 200. The top of the preparation tank 200 is provided with a tank cover 202. A stirring paddle 600 is inserted into the stirring shaft 201, and the top of the stirring paddle 600 abuts against the bottom of the tank cover 202. That is, an insertion limiting block 203 is fixedly connected to the area of ​​the stirring shaft 201 inside the preparation tank 200. The bottom end of the paddle shaft of the stirring paddle 600 is provided with an insertion hole 204. The inner wall of the insertion hole 204 is provided with a limiting groove 205 matching the insertion limiting block 203. The stirring shaft 201 passes into the insertion hole 204, and the insertion limiting block is fitted into the limiting groove 205. The bottom of the tank cover 202 is fixedly connected to a rotating platform 206, which has a rotating groove 207. The top of the shaft of the stirring paddle 600 is fixedly connected to a rotating disk 208, which is fitted into the rotating groove 207. When the stirring shaft 201 rotates, it can drive the stirring paddle 600 to rotate. After the tank cover 202 is removed, the stirring paddle 600 can be disassembled for easy cleaning, thus avoiding the hardened residue on the surface of the stirring paddle 600 from affecting the stirring effect. Of course, multiple sets of stirring paddles 600 can be set, with different blades on each set to adapt to different engineering needs.

[0057] To facilitate the placement and removal of the can lid 202, a handle 209 is fixedly connected to the can lid 202. In addition, a feeding port 210 is fixedly connected to the can lid 202, and a transparent sealing cover plate 211 is embedded in the feeding port 210. After the stirring paddle 600 is installed with the can lid 202, the raw materials are fed into the preparation tank 200 through the feeding port 210. This makes the installation of the stirring paddle 600 convenient, and the sealing cover plate 211 seals the feeding port 210 to prevent the raw materials from splashing out during stirring. The transparent sealing cover plate 211 also allows the internal stirring to be viewed.

[0058] Furthermore, to ensure the excellent stability of the can lid 202 after installation—that is, when the agitator 600 rotates, the can lid 202 can be stably placed on the preparation tank 200—a locking mechanism 300 is also provided on the device platform 100. The locking mechanism 300 is mainly used to lock the can lid 202 to the preparation tank 200. Specifically, the locking mechanism 300 includes a fixed locking platform 301, a movable locking platform 302, and a traction component 303. The fixed locking platform 301 is fixedly connected to the outer wall of the preparation tank 200. The fixed locking platform 301 has a locking socket 304, and a first locking hole 305 passes through the locking socket 304. The can lid 202 is matched with the fixed locking platform 302. A movable locking platform 302 is fixedly connected to the platform 301. The movable locking platform 302 is provided with a second locking hole 306. The movable locking platform 302 is fitted into the locking socket 304, and the first locking hole 305 corresponds to the second locking hole 306. Furthermore, the device platform 100 is also provided with a traction component 303. The traction component 303 is provided with a locking rod 307. Through the traction component 303, the locking rod 307 can be pulled through or out of the first locking hole 305 and the second locking hole 306, thereby realizing the locking between the tank cover 202 and the preparation tank 200. This prevents personnel from suddenly removing the tank cover 202 during normal operation of the device. At this time, the internal stirring paddle 600 is still rotating at high speed, which could cause injury to personnel.

[0059] To further enhance the safety of the device, and with further optimization, a power supply platform 308 is also provided on the preparation tank 200 corresponding to the locking platform 301. A push-button power switch is fixedly connected to the power supply line of the power motor 500. A main switch is also provided on the power supply line. The power switch corresponds to the first locking hole 305. When the traction component 303 drives the locking rod 307 through the first locking hole 305 and the second locking hole 306 and presses down the power switch, the circuit is connected. The operation of the power motor 500 can be achieved by operating the main switch. When the locking rod 307 is not pressed down on the power switch, the circuit is disconnected, and the power motor 500 cannot be started by the main switch. This structural design ensures that the tank cover 202 is locked and the power switch is correctly activated before the device is started. This design can effectively avoid safety accidents caused by misoperation when the device is not fully installed. By combining physical locking and circuit control, the safety threshold of operation is greatly increased and the potential risks during operation are reduced.

[0060] However, with the above-mentioned safety structure, the vibration generated during the operation of the device may cause the locking rod 307 to move, which in turn causes the power switch to disconnect the circuit and affect the normal operation of the device. Therefore, the above-mentioned traction component 303 adopts the following structure:

[0061] The traction component 303 includes a sliding column 309, a lead screw 310, a traction platform 311, a first worm gear 312, and a first worm wheel 313. The sliding column 309 is fixedly connected to the locking platform 301 on the device base 100. The traction platform 311 is slidably connected to the sliding column 309. The lead screw 310 is threadedly connected to the traction platform 311. One end of the lead screw 310 is fixedly connected to an operating shaft 314, which is rotatably connected to the device base 100. The first worm wheel 313 is fixedly connected to the operating shaft 314. The first worm gear 312 is rotatably connected to the device base 100 to match the first worm wheel 313. The first worm gear 312 is meshed with the first worm wheel 313. An operating turntable 315 is fixedly connected to the first worm gear 312, and a locking rod 307 is fixedly connected to the traction table 311. When the operating turntable 315 is rotated, the worm gear drives the worm wheel to rotate, which in turn causes the lead screw 310 to rotate. This causes the traction table 311 to drive the locking rod 307 through the locking hole and press down the power switch, which meets the above functional requirements. Furthermore, the self-locking effect of the first worm gear 312 and the first worm wheel 313 can prevent the locking rod 307 from being displaced due to vibration. The aforementioned traction component 303 is mounted on the mounting frame 102.

[0062] Furthermore, a pump body 400 and the aforementioned power motor 500 are fixedly connected to the machine base 101. The pump body 400 is connected to the preparation tank 200 via a first pipe 700, and to the grouting gun 900 via a second pipe 800. An electric control valve can be installed on the first pipe 700 to control the liquid flow. The power motor 500 is connected to the stirring shaft 201 via a first transmission assembly, and the power motor 500 is connected to the pump body 400 via a second transmission assembly 1100. The second transmission assembly 1100 is also equipped with a ratchet assembly 1101, so that when the power motor 500 rotates forward under the action of the ratchet assembly 1101, the pump body 400 does not work; when the power motor 500 rotates in the reverse direction, the pump body 400 works. Thus, the power motor 500, through the first transmission assembly, serves as the stirring shaft... Power is provided by motor 201, which powers pump body 400 via second transmission component 1100. When motor 500 rotates in the forward direction, pump body 400 does not operate, thus preventing pump body 400 from pumping slurry from preparation tank 200 to grouting gun 900. However, when motor 500 rotates in the reverse direction, pump body 400 operates, allowing it to pump slurry from preparation tank 200 to grouting gun 900, thus achieving grouting. Stirring shaft 201 can drive stirring paddle 600 to stir raw materials in preparation tank 200 in both forward and reverse motor operation. When motor rotates in the forward direction, stirring paddle 600 ensures uniform stirring of raw materials. When motor rotates in the reverse direction, stirring paddle 600 prevents sedimentation of the stirred slurry. This design is reasonable, has excellent performance, and reduces the number of motors, thus reducing the failure rate.

[0063] Furthermore, the first transmission assembly includes a first gear 1001, a second gear 1002, a reversing gear 1003, a first sector gear 1004, and a second sector gear 1005. Specifically, the first gear 1001 is fixedly connected to the stirring shaft 201 at the bottom of the preparation tank 200, and the second gear 1002 is also fixedly connected to the bottom of the first gear 1001. The reversing gear 1003 is rotatably connected to the bottom surface of the preparation tank 200, and the reversing gear 1003 meshes with the first gear 1001. A drive shaft 1010 is rotatably connected to the bottom of 00. A first sector gear 1004 is fixedly connected to the drive shaft 1010 corresponding to the reversing gear 1003. The first sector gear 1004 can mesh with the reversing gear 1003 by rotation. A second sector gear 1005 is fixedly connected to the drive shaft 1010 at the bottom of the first sector gear 1004. The second sector gear 1005 can mesh with the second gear 1002 by rotation. The toothed surfaces of the first sector gear 1004 and the second sector gear 1005 face different directions.

[0064] Furthermore, a second worm gear 1006 is fixedly connected to the bottom of the second sector gear 1005 on the drive shaft 1010. An input shaft 1007 is rotatably connected to the machine base 100 to match the second worm gear 1006. A second worm 1008 is mounted on the input shaft 1007, and the second worm 1008 meshes with the second worm gear 1006. The power output shaft of the power motor 500 is connected to the input shaft 1007 via a first power transmission component 1009. Thus, the power motor 500 can first drive the drive shaft 1010 to rotate, causing the second sector gear 1005 to mesh with the second gear 1002, thereby agitating the drive shaft. The stirring shaft 201 rotates, which in turn causes the internal stirring paddle 600 to rotate. When the drive shaft 1010 rotates a certain angle, the second sector gear 1005 disengages from the second gear 1002. At this time, the first sector gear 1004 drives the reversing gear 1003 to rotate, and then the reversing gear 1003 drives the first gear 1001 to rotate. At this time, the stirring shaft 201 also rotates, and the direction of rotation is opposite to the first rotation direction. This cycle continues, so that the stirring shaft 201 drives the stirring paddle 600 to stir the raw materials in both directions without changing the rotation direction of the drive shaft 1010, ensuring excellent stirring effect of the raw materials.

[0065] Furthermore, when the first sector gear 1004 just disengages from the reversing gear 1003, the second sector gear 1005 does not mesh with the second gear 1002, and when the second sector gear 1005 just disengages from the second gear 1002, the first sector gear 1004 does not mesh with the reversing gear 1003. This ensures that when the first sector gear 1004 or the second sector gear 1005 drives the stirring shaft 201 to rotate, there is a certain amount of clearance before the second sector gear 1005 or the first sector gear 1004 meshes with the second gear 1002 or the first gear 1001. This clearance reduces the rotational force of the stirring paddle 600 due to inertia, thereby avoiding direct gear meshing and reducing the service life of the gears.

[0066] Furthermore, the second transmission assembly also includes an output shaft 1102, a second power transmission component 1103, and a pump shaft 1104. The pump shaft 1104 is fixedly connected to the power input end of the pump body 400, and an input shaft 1007 is fixedly connected to the power output main shaft. A ratchet assembly 1101 is provided on the input shaft 1007. The input shaft 1007 and the pump shaft 1104 are connected by the second power transmission component 1103, and the second power transmission component 1103 is located on the power output end side of the ratchet assembly 1101. In this way, the power motor 500 can drive the input shaft 1007 to rotate, and the ratchet assembly 1101 can achieve the above-mentioned desired effect.
