Description

Technical Field

[0001] The invention relates to the field of grouting devices, and in particular to a multifunctional grouting device. Background Art

[0002] There are many types of grouting pumps, which are mainly classified according to their working principles and application areas. The following are some common types of grouting pumps: Piston grouting pump: uses the reciprocating motion of the piston to generate pressure, suitable for high-pressure and high-flow grouting operations. Gear grouting pump: conveys slurry through the meshing rotation of two gears, suitable for thicker slurries, and has a stable flow output. Screw grouting pump: uses the screw rotation principle to convey slurry, suitable for conveying slurry with higher viscosity, and has good self-priming ability. Plunger grouting pump: pressurizes slurry through the reciprocating motion of the plunger, suitable for high-pressure grouting and precise control occasions. Dual-liquid grouting pump: can inject two different slurries (such as cement slurry and chemical slurry) at the same time, and is often used in grouting projects that require two slurries to be mixed. Hydraulic grouting pump: uses the hydraulic system to provide power, has the characteristics of high efficiency and high pressure, and is widely used in underground engineering and geological grouting. Electric grouting pump: driven by an electric motor, suitable for small and medium-sized grouting operations, simple operation and convenient maintenance. Pneumatic grouting pump: driven by compressed air, suitable for environments with high humidity and occasions with low power requirements. Each grouting pump has its specific application scenarios and advantages and disadvantages. Choosing the right type can improve the efficiency and quality of grouting work. In the process of using the grouting pump, you may encounter blockage problems. Solid particles or impurities in the slurry may cause the pump's delivery pipe or valve to be blocked. Clean and inspect regularly to ensure the quality and filtration of the slurry.

However, in actual use, the main reason for pipeline blockage is the viscosity and density of the mortar itself, which causes the mortar particles to accumulate and adhere to the inner wall of the pipeline during transportation, thereby forming a blockage and affecting the grouting efficiency.

DETAILED DESCRIPTION

[0019] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0020] An embodiment of a multifunctional grouting device of the present invention is as follows Figures 1 to 11 As shown, it includes a moving assembly 1 for driving the device to move and a storage box 2 for storing slurry, a transmission mechanism 3 for extruding and conveying the slurry, and a diameter-reducing mechanism 4 for connecting the transmission mechanism 3 and an external conveying pipeline and preventing the slurry from blocking the pipeline. The transmission mechanism 3 is installed on the moving assembly 1, the storage box 2 is installed at the feeding end of the transmission mechanism 3, and the diameter-reducing mechanism 4 is installed at the discharging end of the transmission mechanism 3; like Figure 3 and Fig.11As shown, the transmission mechanism 3 includes a sealing cylinder 31, an extrusion cylinder 32 is axially installed inside the sealing cylinder 31, an extrusion spiral blade 33 is arranged between the outside of the extrusion cylinder 32 and the sealing cylinder 31, a power shaft 36 is installed inside the extrusion cylinder 32, the power shaft 36 is slidably connected to the extrusion cylinder 32 through a spline, one end of the power shaft 36 extends out of the extrusion cylinder 32 and is connected to a power assembly 35, the end of the power shaft 36 away from the power assembly 35 is connected to the extrusion cylinder 32 through a reset assembly 37, and the end of the extrusion cylinder 32 away from the power assembly 35 is connected to the sealing cylinder 31 through a support assembly 34; like Figure 5-6 As shown, the reducing mechanism 4 includes a reducing sleeve 42, which is fixedly mounted on the discharge end of the sealing cylinder 31 through a flange, and a discharge pipe 41 is installed on the discharge end of the reducing sleeve 42. A conical force frame 43 is rotatably connected inside the reducing sleeve 42, and the conical force frame 43 is connected to the support assembly 34 through an adjusting assembly.

[0021] Further, such as Figure 4 As shown, the adjustment assembly includes a first support ring 343, the interior of the first support ring 343 is connected to a center connecting block 341 through a cross 342, the center connecting block 341 is fixed to the extrusion cylinder 32, and a second support ring 44 is fixedly connected to one end of the conical force frame 43 close to the support assembly 34, and a matching ring 344 is arranged between the first support ring 343 and the second support ring 44.

[0022] Further, such as Figure 8-10 As shown, the cross-section of the matching ring 344 is a T-shaped structure, and the matching ring 344 is composed of a wide ring and a narrow ring. The wide ring of the matching ring 344 fits the inner side of the joint between the first support ring 343 and the second support ring 44, and the wide surface size of the matching ring 344 is larger than the gap between the first support ring 343 and the second support ring 44. The narrow ring of the matching ring 344 is arranged in the gap between the first support ring 343 and the second support ring 44. When the matching ring 344 and the second support ring 44 are in the initial state, there is a gap between the narrow ring of the matching ring 344 and the first support ring 343 and the second support ring 44. When in the initial state, the second support ring 44 and the first support ring 343 do not match, and the second support ring 44 is squeezed by the paddle material so that it can rotate freely.

[0023] Further, such as Figure 5-9 As shown, the conical force frame 43 is composed of an array of arc rods, and the spiral direction of the arc rods is the same as the spiral direction of the extrusion spiral blades 33. Because the arc rods have the same spiral direction as the extrusion spiral blades 33, when the paddle material extrudes the arc rods, the arc rods will rotate due to the extrusion force of the paddle material, and the rotation direction at this time is opposite to the rotation direction of the extrusion spiral blades 33.

[0024] Further, such as Fig.10As shown, the arc rod of the conical force-bearing frame 43 is bent toward the inner side of the reducing sleeve 42, and a gap is set between the center of the arc rod and the inner wall of the reducing sleeve 42 at the initial position. Because there is a gap between the arc rod and the reducing sleeve 42, when the pressure at the conical force-bearing frame 43 increases, the arc rod of the conical force-bearing frame 43 will be squeezed to become straight, and the conical force-bearing frame 43 will squeeze the second support ring 44 to move closer to the first support ring 343. When the distance moved by the second support ring 44 is greater than the gap between the matching ring 344 and the first support ring 343 and the second support ring 44, the rotational power of the first support ring 343 can be transmitted to the second support ring 44, thereby driving the second support ring 44 to rotate. At this time, the second support ring 44 has the same rotation direction as the first support ring 343, that is, the second support ring 44 drives the conical force-bearing frame 43 to reverse. At this time, the agglomerates adhered to the conical force-bearing frame 43 are subjected to reverse extrusion force, thereby destroying the agglomerates.

[0025] Furthermore, an output tube 45 is provided inside the discharge pipe 41. The arc rod protrudes inwardly from the output tube 45 at the matching position of the arc rod and the output tube 45. The protruding edge can not only guide the arc rod to rotate by the paddle material, but also avoid the formation of a concave shape at the junction, thereby preventing the paddle material from sticking to the concave.

[0026] Furthermore, a plurality of spherical bumps are provided in a circular array on the inner wall of the reducing sleeve 42 near the second support ring 44, and grooves are provided on the conical force-bearing frame 43 corresponding to the circular array of spherical bumps. The rotation of the conical force-bearing frame 43 is utilized to make the spherical bumps and the grooves interlock and cooperate with each other, so that the conical force-bearing frame 43 oscillates, thereby further improving the effect of destroying the agglomerates.

[0027] Furthermore, the reset assembly 37 includes a reset spring, and both ends of the reset spring are connected to the extrusion cylinder 32 and the reset assembly 37 by bolts.

[0028] Furthermore, the extrusion spiral blade 33 is connected to the extrusion cylinder 32 by welding.

[0029] Furthermore, the cross 342 is composed of four support columns, and the support columns have a pointed structure at the incoming end facing the paddle material. The sharp corner of the cross 342 is parallel to the axial direction of the extrusion cylinder 32. Because the paddle material makes a spiral motion under guidance, the sharp corner of the cross 342 is used to destroy the inherent spiral power, thereby preventing the paddle material from forming a steady-state conveying environment. A stable paddle material conveying environment will continuously impact a certain place, thereby forming agglomerates, thereby reducing the generation of agglomerates.

[0030] The working principle is as follows: before use, connect the outlet end of the discharge pipe 41 to the hose, pour the slurry into the storage box 2, start the power assembly 35, and make the power assembly 35 rotate through the extrusion cylinder 32 and the extrusion spiral blade 33, so that the slurry enters the extrusion cylinder 32 through the opening on the sealing cylinder 31; The paddle material is transmitted to one side of the discharge pipe 41 under the power of the extruding spiral blade 33. The paddle material first passes through the cross 342. Because the paddle material performs a spiral motion under the guidance, the sharp corner of the cross 342 is used to destroy the inherent spiral power, so as to avoid the paddle material from forming a stable conveying environment (a stable paddle material conveying environment will continuously impact a certain place, thereby forming agglomerates), thereby reducing the generation of agglomerates. The paddle material continues to be transmitted. When the paddle material passes through the position of the conical force frame 43, because the arc rod of the conical force frame 43 is spirally distributed, after the paddle material impacts the spiral rod, it can drive the spiral rod and the conical force frame 43 to rotate as a whole, so that the paddle material reverses and the conical force frame 43 can rotate irregularly (because the viscosity of the paddle material itself and the power it receives are not stable, the conveying pressure will fluctuate, thereby generating irregular power). The irregular rotation is used to reduce the probability of agglomeration, and when agglomerates occur at a certain place, the irregular power can also be used to destroy the agglomerates in time; When the agglomerates are accumulated, the flow rate at the outlet becomes low, and the pressure at the reducing sleeve 42 increases. When the pressure at the conical force-bearing frame 43 increases, the arc rod of the conical force-bearing frame 43 is squeezed to become straight, and the conical force-bearing frame 43 squeezes the second support ring 44 to move closer to the first support ring 343. When the distance moved by the second support ring 44 is greater than the gap between the matching ring 344 and the first support ring 343 and the second support ring 44, the rotational power of the first support ring 343 can be transmitted to the second support ring 44, thereby driving the second support ring 44 to rotate. At this time, the second support ring 44 has the same rotation direction as the first support ring 343, that is, the second support ring 44 drives the conical force-bearing frame 43 to reverse. At this time, the agglomerates attached to the conical force-bearing frame 43 are subjected to reverse extrusion force, thereby destroying the agglomerates, and the rotation of the conical force-bearing frame 43 is used to make the spherical protrusions and the depressions interlock, so that the conical force-bearing frame 43 forms an oscillation, further improving the agglomeration destruction effect. At the same time, if a slurry mixed with large particles is transmitted, if the large particles are stuck at the junction of the extrusion spiral blade 33 and the opening of the sealing cylinder 31, the conventional structure may cause the extrusion spiral blade 33 to be stuck, while in the present scheme, a spring is arranged between the extrusion cylinder 32 and the power shaft 36. When the extrusion spiral blade 33 is stuck, the extrusion spiral blade 33 is driven by the extrusion power to drive the extrusion cylinder 32 to move toward the side of the power component 35. At the same time, the position where the extrusion spiral blade 33 contacts the large particles slides, thereby utilizing the staggered power to extrude the stuck particles. When the particles are extruded, the extrusion spiral blade 33 and the extrusion cylinder 32 need to be reset. Then, the extrusion spiral blade 33 and the extrusion cylinder 32 undergo an instantaneous axial movement. In conjunction with the sealing space inside the sealing cylinder 31, the extrusion spiral blade 33 undergoes a piston-like motion. At the same time, at the moment when the extrusion spiral blade 33 is reset, the first support ring 343 impacts the matching ring 344 and the second support ring 44, thereby providing a shock force to the second support ring 44 again, further improving the effect of destroying agglomerates.

[0031] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
