Description

Technical Field

[0001] This invention relates to the field of grouting equipment technology, and more specifically to a grouting construction equipment for water conservancy projects. Background Technology

[0002] Water conservancy projects are engineering projects built to control and regulate surface water and groundwater in nature to achieve the purpose of eliminating harm and promoting benefits. They are also called water engineering projects. During the construction of water conservancy projects, a certain proportion of cement grout needs to be injected into the foundation voids, cracks or cracks in the building itself under appropriate pressure for filling, bonding and seepage prevention or reinforcement treatment. This process is called grouting.

[0003] The shortcomings of existing technologies: In the process of using existing grouting equipment, various materials are mixed in a container to form a slurry. After the slurry is prepared, it needs to be transferred to a discharge box for discharge before grouting. However, when discharging the slurry, a large amount of slurry usually adheres to the inner wall of the container, which is difficult to clean. Moreover, the material transfer efficiency is low each time, which takes a certain amount of time and cannot continuously prepare slurry. After the slurry in the discharge box is emptied, it is necessary to wait for the slurry preparation to be completed before grouting can be carried out. The continuity of the entire grouting operation is affected, which seriously affects the efficiency of grouting construction. To address this, we propose a grouting construction equipment for water conservancy projects. Summary of the Invention

Preferably, a fixed base is installed on the surface of the discharge box, a drive motor is installed on the upper end of the fixed base, a drive rod installed on the output end of the drive motor is rotatably connected inside the discharge box, a rotating rod is rotatably connected inside the mixing box and the rotating tube, the drive rod and the rotating rod are connected by a first transmission sprocket set, the rotating rod and the connecting rod are connected by a second transmission sprocket set, and the connecting rod and the first reciprocating lead screw are connected by a third transmission sprocket set.

[0006] Preferably, the surface of the discharge box is rotatably connected to a pair of fixed shafts and a pair of worm gears via a rotating seat. The fixed shafts and rotating rods are connected by a first bevel gear set, and the connecting shaft and worm gears are connected by a second bevel gear set. A pair of mounting shafts are rotatably connected inside the discharge box. A worm wheel mounted on the circumferential surface of the mounting shaft meshes with the worm gear. A concave-convex disc is mounted on the end face of the mounting shaft. The sliding rod is located between the concave-convex discs, and the concave and convex surfaces of the concave-convex discs are transitioned by an arc.

[0007] Preferably, a first support ring and a second support ring are installed on the circumference of the slide rod, a third support ring is installed on the inner wall of the connecting rod, and a return spring is installed between the second support ring and the third support ring.

[0008] Preferably, a hydraulic cylinder is installed on the surface of the discharge box, a lifting rack is installed at the output end of the hydraulic cylinder, and a sector gear installed on the circumferential surface of the rotating tube meshes with the lifting rack.

[0009] Preferably, the slurry discharge assembly includes a servo motor, a drive shaft, a rotating shaft, auger blades, a discharge pipe, and a connector. The servo motor is mounted on the upper end of the base, the drive shaft is mounted on the output end of the servo motor, the rotating shaft is rotatably connected to the discharge box and fixedly connected to the drive shaft, the auger blades are mounted on the circumference of the rotating shaft, the discharge pipe is mounted on the front end of the discharge box, and a discharge connector is installed at the front end of the discharge pipe.

[0010] Preferably, a pair of guide frames and multiple first protrusions are installed on the surface of the discharge box. An mounting plate is slidably connected to the circumference of the guide frame. A second reciprocating screw is rotatably connected inside the guide frame and threadedly connected to the mounting plate. Multiple sliding shafts are slidably connected inside the mounting plate. A second protrusion is installed on the end face of each sliding shaft. A vibration spring is installed between the second protrusion and the mounting plate. The second protrusion is slidably connected to the first protrusion and the discharge box.

[0011] Preferably, a rotating frame is mounted on the surface of the discharge box, and a driven shaft is rotatably connected between the rotating frame and the discharge box. The drive shaft and the driven shaft are connected through a first differential sprocket set, and the driven shaft and the second reciprocating screw are connected through a second differential sprocket set.

[0012] The technical effects and advantages of this invention are as follows: 1. This invention involves adding materials to a mixing tank, controlling the rotation of a connecting rod to drive the stirring blades to mix the materials. During the mixing process, the reciprocating sliding of a slide rod drives a transmission rack, causing the transmission gear to rotate, thereby adjusting the angle of the stirring blades and continuously changing the material flow direction, thus improving mixing efficiency. After mixing is complete, the mixing tank rotates 180 degrees, so that the opening of the mixing tank faces downwards, and the slurry is quickly discharged into the discharge box. The empty space above can be used to continue feeding materials and start stirring. At the same time, the scraper removes residual slurry from the tank wall to ensure that the slurry is completely discharged. Finally, the slurry discharge component is controlled to discharge the slurry from the discharge box for subsequent filling. Because the mixing tank can rotate, it is possible to immediately add new materials to another mixing tank for the next batch of mixing while one mixing tank is discharging materials, ensuring the continuity of slurry production, meeting the discharge requirements of the slurry discharge component, and significantly improving work efficiency.

[0013] 2. This invention controls the rotation of the second reciprocating screw to drive the mounting plate to slide along the guide frame. During the sliding process, when the second protrusion contacts the first protrusion, the sliding shaft retracts within the mounting plate. When the second protrusion passes the first protrusion, under the action of the vibration spring, the second protrusion quickly rebounds and strikes the lower part of the discharge box, causing the lower part of the discharge box to vibrate, compacting the slurry, expelling internal air bubbles, reducing the gas content in the slurry, improving the density and fullness of the slurry, and preventing the slurry from adhering to the inner wall of the discharge box, facilitating subsequent cleaning of the equipment.

[0016] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings. In addition, the forms of the various structures described in the following embodiments are merely illustrative. The grouting construction equipment for water conservancy projects involved in the present invention is not limited to the structures described in the following embodiments. All other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0017] like Figure 1-12As shown, in one embodiment, a grouting construction device for water conservancy projects is proposed, including a base 1, a discharge box 101 installed on the upper end of the base 1, a grout discharge assembly 2 disposed inside the discharge box 101, a mixing box 103 rotatably connected inside the discharge box 101 via a rotating pipe 102, a pair of mixing tanks 104 opened inside the mixing box 103, and a mixing assembly 3 disposed inside the mixing box 103, the mixing assembly 3 including a stirring mechanism 31 and a scraping mechanism 32, the stirring mechanism 31 including a connecting rod 311 and a connecting shaft 32. 12. Stirring blades 313, transmission gears 314 and slide rods 315, a pair of connecting rods 311 are rotatably connected in the mixing box 103, multiple connecting shafts 312 are rotatably connected in the connecting rods 311, stirring blades 313 are all installed on the end face of the connecting shafts 312, transmission gears 314 are all installed on the circumferential surface of the connecting shafts 312, slide rods 315 are slidably connected in the connecting rods 311, multiple transmission racks 316 are installed on the circumferential surface of the slide rods 315, and the transmission racks 316 mesh with the transmission gears 314; The scraping mechanism 32 includes a guide rod 321, a scraper frame 322, and a first reciprocating screw 323. Multiple guide rods 321 are installed inside the mixing box 103. The scraper frame 322 is slidably connected to the circumferential surface of the guide rod 321 and slidably connected to the mixing tank 104. A pair of first reciprocating screws 323 are rotatably connected inside the mixing box 103. The scraper frame 322 is threadedly connected to the first reciprocating screws 323.

[0018] In practical application, materials are added to the mixing tank 104. Then, the connecting rod 311 is rotated, driving the connecting shaft 312 and the stirring blades 313 to rotate. The rotating stirring blades 313 uniformly stir the materials in the mixing tank 104 to form a slurry. During the rotation of the stirring blades 313 by the connecting rod 311, the sliding rod 315 reciprocates within the connecting rod 311, synchronously driving the transmission rack 316 to slide. The transmission rack 316 drives the transmission gear 314 to rotate, which in turn drives the connecting shaft 312 to rotate. This allows adjustment of the angle of the stirring blades 313. Each time the stirring blades 313 rotate for a period of time, the angle of the stirring blades 313 can be changed by controlling the sliding rod 315, continuously adjusting the flow direction of the materials during stirring, thereby improving slurry preparation. To improve efficiency, once the material is mixed, the rotating tube 102 can be controlled to rotate, causing the mixing tank 103 to rotate 180 degrees, thus swapping the positions of the upper and lower mixing tanks 104. This allows the mixing tank 104 containing slurry to face downwards, enabling the slurry in the mixing tank 104 to be quickly discharged into the discharge box 101. Simultaneously, materials can be added to the upper mixing tank 104, and the mixing component 3 will operate again to continue preparing slurry. When the mixing component 3 operates, it can drive the first reciprocating screw 323 to rotate. The first reciprocating screw 323 drives the scraper 322 to slide within the mixing tank 104, scraping off and cleaning the slurry adhering to the inner wall of the mixing tank 104, so that all the slurry in the mixing tank 104 is discharged into the discharge box 101. Then, the slurry discharge component 2 is controlled to operate, and the slurry in the discharge box 101 can be discharged, completing the subsequent grouting operation.

[0019] like Figure 6 and 7 As shown, in one embodiment, a fixed base 4 is installed on the surface of the discharge box 101, and a drive motor 401 is installed on the upper end of the fixed base 4. A drive rod 402 installed at the output end of the drive motor 401 is rotatably connected inside the discharge box 101. A rotating rod 403 is rotatably connected inside the mixing box 103 and the rotating tube 102. The drive rod 402 and the rotating rod 403 are connected by a first transmission sprocket set 404. The rotating rod 403 and the connecting rod 311 are connected by a second transmission sprocket set 405. The connecting rod 311 and the first reciprocating screw 323 are connected by a third transmission sprocket set 406.

[0020] In practical application, this invention controls the operation of the drive motor 401, which in turn drives the drive rod 402 to rotate. The drive rod 402, through the first transmission sprocket set 404, drives the rotating rod 403 to rotate. The rotating rod 403, through the second transmission sprocket set 405, drives the connecting rod 311 to rotate, thus achieving the effect of controlling the rotation of the stirring blade 313. At the same time, the rotating rod 403, through the third transmission sprocket set 406, drives the first reciprocating screw 323 to rotate, thus achieving the effect of controlling the scraper to slide back and forth in the mixing tank 104. When the rotating stirring blade 313 stirs the material in the mixing tank 104, the scraper can slide synchronously in the mixing tank 104.

[0021] like Figure 3 , 4 As shown in Figures 5, 13, 14, and 15, in one embodiment, a pair of fixed shafts 501 and a pair of worm gears 502 are rotatably connected to the surface of the discharge box 101 via a rotating seat 5. The fixed shafts 501 and the rotating rod 403 are connected by a first bevel gear set 503, and the fixed shafts 501 and the worm gears 502 are connected by a second bevel gear set 504. A pair of mounting shafts 505 are rotatably connected inside the discharge box 101. A worm wheel 506 mounted on the circumferential surface of the mounting shaft 505 meshes with the worm gears 502. A concave-convex disc 507 is mounted on the end face of the mounting shaft 505. A sliding rod 315 is located between the concave-convex discs 507. The concave surface and the convex surface of the concave-convex disc 507 are transitioned by an arc.

[0022] In practical application, when the drive motor 401 controls the rotating rod 403 to rotate, the rotating rod 403 drives the fixed shaft 501 to rotate via the first bevel gear set 503. The fixed shaft 501 drives the worm gear 502 to rotate via the second bevel gear set 504. The worm gear 502 drives the worm wheel 506 to rotate. The worm wheel 506 drives the mounting shaft 505 to rotate. The mounting shaft 505 drives the concave-convex disc 507 to rotate. Since the concave-convex surfaces of the two concave-convex discs 507 are arranged in opposite directions... The concave surface of the front concave-convex disk 507 is located on top, and the convex surface of the rear concave-convex disk 507 is located on top. In the initial position, the slide rod 315 is located between the concave surface of the front concave-convex disk 507 and the convex surface of the rear concave-convex disk 507. As the concave-convex disks 507 on both sides rotate simultaneously, when the concave surface and the convex surface switch, the slide rod 315 can be pushed to slide in the connecting rod 311, which synchronously drives the rack to move, thereby achieving the effect of changing the angle of the stirring blade 313.

[0023] like Figure 10 and 11 As shown, in one embodiment, a first support ring 6 and a second support ring 601 are installed on the circumference of the slide rod 315, a third support ring 602 is installed on the inner wall of the connecting rod 311, and a return spring 603 is installed between the second support ring 601 and the third support ring 602.

[0024] In practical application, after the materials in the mixing tank 104 are mixed, the mixing component 3 can be stopped after the concave-convex disc 507 is reset. At this time, the rotating tube 102 can be controlled to rotate, thus achieving the effect of switching the position of the mixing tank 104. When the mixing box 103 rotates, the slide rod 315 will gradually disengage from the concave-convex disc 507. At this time, the reset spring 603 pushes the second support ring 601, causing the slide rod 315 to move backward, so that the first support ring 6 installed on the circumference of the slide rod 315 is stably attached to the connecting rod 311, limiting the length of the slide rod 315 extending on both sides of the connecting rod 311. This length is consistent with the length of the slide rod 315 extending when it disengages from the concave-convex disc 507, ensuring that the other slide rod 315 moves stably between the concave-convex discs 507 as the mixing box 103 rotates, thus achieving stable switching of the slide rod 315 between the concave-convex discs 507.

[0025] like Figure 3 and 4 As shown, in one embodiment, a hydraulic cylinder 7 is installed on the surface of the discharge box 101, and a lifting rack 701 is installed at the output end of the hydraulic cylinder 7. A sector gear 702 installed on the circumferential surface of the rotating tube 102 meshes with the lifting rack 701.

[0026] In practical application, the hydraulic cylinder 7 is controlled to operate, which in turn drives the lifting rack 701 to move. The lifting rack 701 drives the sector gear 702 to rotate, which in turn drives the rotating tube 102 to rotate, thereby achieving the effect of controlling the rotation of the mixing box 103.

[0027] like Figure 13 As shown, in one embodiment, the slurry discharge assembly 2 includes a servo motor 201, a drive shaft 202, a rotating shaft 203, an auger blade 204, a discharge pipe 205, and a connector. The servo motor 201 is mounted on the upper end of the base 1, the drive shaft 202 is mounted on the output end of the servo motor 201, the rotating shaft 203 is rotatably connected to the discharge box 101 and fixedly connected to the drive shaft 202, the auger blade 204 is mounted on the circumference of the rotating shaft 203, the discharge pipe 205 is mounted on the front end of the discharge box 101, and a discharge connector 206 is installed at the front end of the discharge pipe 205.

[0028] In practical application, after the slurry in the mixing tank 104 is discharged into the discharge box 101, the servo motor 201 can be controlled to operate. The servo motor 201 drives the auger blades 204 to rotate through the drive shaft 202. The auger blades 204 stably, continuously, stably, and controllably transport the slurry to the discharge pipe 205, and then output it through the discharge connector 206 to realize the subsequent grouting operation.

[0029] In one embodiment of the present invention, the discharge connector 206 can be connected to an external hose or main pumping system to realize subsequent grouting operations. The discharge connector 206 and the discharge pipe 205 are connected by threads, and the drive shaft 202 and the rotating shaft 203 are connected by threads. By unscrewing the threads, the auger blade 204 can be pulled out and disassembled, which facilitates the cleaning of the equipment.

[0030] like Figure 1 and 16 As shown, in one embodiment, a pair of guide frames 8 and a plurality of first protrusions 801 are mounted on the surface of the discharge box 101. A mounting plate 802 is slidably connected to the circumferential surface of the guide frame 8. A second reciprocating screw 803 rotatably connected inside the guide frame 8 is threadedly connected to the mounting plate 802. A plurality of sliding shafts 804 are slidably connected inside the mounting plate 802. A second protrusion 805 is mounted on the end face of each sliding shaft 804. A vibration spring 806 is installed between the second protrusion 805 and the mounting plate 802. The second protrusion 805 is slidably connected to the first protrusion 801 and the discharge box 101.

[0031] In practical application, after the slurry is discharged into the discharge box 101, the second reciprocating screw 803 is rotated, causing the mounting plate 802 to slide on the guide frame 8. When the mounting plate 802 slides, when the second protrusion 805 is in contact with the first protrusion 801, the sliding shaft 804 will retract in the mounting plate 802. When the second protrusion 805 passes the first protrusion 801, the vibration spring 806 causes the second protrusion 805 to strike the lower part of the discharge box 101, causing it to vibrate. This vibration is transmitted to the slurry, which can compact the slurry and expel air bubbles. This process not only reduces the gas content in the slurry but also prevents air bubbles from lingering in the slurry and forming voids, thereby improving the density and fullness of the slurry. During the slurry discharge process, it also prevents the slurry from adhering to the inner wall of the discharge box 101, allowing it to be discharged fully. It also facilitates subsequent cleaning of the equipment.

[0032] like Figure 2 , 3 As shown in Figure 13, in one embodiment, a rotating frame 807 is mounted on the surface of the discharge box 101, and a driven shaft 808 is rotatably connected between the rotating frame 807 and the discharge box 101. The drive shaft 202 is connected to the driven shaft 808 through a first differential sprocket set 809, and the driven shaft 808 is connected to the second reciprocating screw 803 through a second differential sprocket set 8010.

[0033] In practical application, when the drive shaft 202 rotates, it drives the driven shaft 808 to rotate through the action of the first differential sprocket set 809. The driven shaft 808 drives the second reciprocating screw 803 to rotate through the action of the second differential sprocket set 8010. This allows the second reciprocating screw 803 to rotate rapidly, thereby driving the mounting plate 802 to move back and forth rapidly. When the second cam passes the first protrusion 801, it can avoid contact with the discharge box 101 along the arc of the first protrusion 801. When the second protrusion 805 passes the first protrusion 801, it can directly contact the discharge box 101, achieving the effect of striking the discharge box 101.

[0034] In one embodiment of the present invention, when slurry is added into the discharge box 101, the drive shaft 202 can be controlled to rotate in the reverse direction. At this time, the auger blade 204 does not output slurry. After the air in the slurry is vibrated out, the drive shaft 202 is controlled to rotate in the forward direction, and the slurry in the discharge box 101 is discharged through the auger blade 204.

[0035] Finally, the following points should be noted: First, in the description of this application, it should be noted that, unless otherwise specified and limited, the terms "installation", "connection", and "linkage" should be interpreted broadly, and can be mechanical or electrical connections, or internal connections between two components, or direct connections.
