Description

Technical Field

[0001] This utility model belongs to the field of construction equipment, specifically a grouting equipment that integrates mixing and grouting. Background Technology

[0002] Grouting is a method of injecting certain solidifiable grouts into cracks or pores in the rock surrounding a tunnel to improve its physical and mechanical properties. Integrated mixing and grouting equipment combines mixing and grouting into one unit, enabling grout mixing and pressurized grouting within the same device, making it one of the more common types of grouting equipment. However, existing equipment typically mixes and injects immediately, requiring waiting for the mixing process to complete before the grout enters the grouting pump. For large-volume grouting operations, this is difficult to match with the grouting process, necessitating frequent shutdowns for mixing, which is extremely inconvenient. Adding a transfer container to temporarily store the grout can alleviate this problem, but it also presents the issue of grout solidification in the transfer container, leading to reduced pumping efficiency, which requires further improvement. Utility Model Content

[0003] The purpose of this invention is to overcome the shortcomings of the existing technology and provide a grouting device that integrates mixing and grouting.

[0004] The present invention adopts the following technical solution:

[0005] A grouting device integrating mixing and injection includes a mixing chamber, a transfer chamber, a grouting mechanism, and a swinging mechanism. The mixing chamber and the transfer chamber are arranged vertically opposite each other. The bottom of the mixing chamber has a discharge port that can extend into the transfer chamber, and the bottom of the transfer chamber has a discharge port. The grouting mechanism includes a grouting chamber, a plunger, and a telescopic cylinder. The grouting chamber has a cavity for temporarily storing liquid, and an inlet and a grouting port are respectively connected on both sides. The inlet and the discharge port are connected, and the grouting port is connected to the external space. The plunger is sealed in the grouting chamber. The telescopic cylinder is connected to the plunger and drives it to move back and forth to pump the liquid in the grouting chamber. The swinging mechanism includes a sliding component and a drive plate. The sliding component is connected to the transfer chamber, and the transfer chamber can move back and forth through the sliding component. The drive plate is located at the bottom of the transfer chamber and is connected to the plunger. When the plunger moves, it can push the drive plate to drive the transfer chamber to move back and forth on the sliding component.

[0006] Preferably, the discharge port extends downward to the bottom of the transfer chamber, and an electrically controlled valve is provided on the discharge port to control the opening or closing of the discharge port. The mixing chamber also includes a detachable mixing paddle installed on the discharge port. The mixing paddle extends outward into the transfer chamber and can mix the slurry in the transfer chamber as the transfer chamber moves.

[0007] Preferably, the telescopic cylinder is a bidirectional hydraulic cylinder, and there are two of each of the discharge port, plunger, grouting chamber and drive plate. The distance between the two drive plates is smaller than the distance between the two plungers. The opposite sides of the two drive plates can contact the opposite surfaces of the plungers respectively. The plungers retract to drive the transfer chamber to move in the same direction.

[0008] Preferably, the sliding assembly includes a base plate, a limiting plate, a guide rail, and sliding wheels. The base plate is disposed above the grouting mechanism and has a clearance groove formed on it to allow the drive plate and the discharge port to pass through and provide movement space. The limiting plate is formed around the base plate to limit the range of movement. The guide rail is disposed on the base plate along the extension and retraction direction of the telescopic cylinder. The sliding wheels are disposed at the bottom of the transfer chamber and can cooperate with the guide rail on it.

[0009] Preferably, it also includes a base, the grouting mechanism is mounted on the base, and the base is also provided with a hydraulic system connected to the telescopic cylinder.

[0010] Preferably, the mixing chamber is equipped with mixing blades and a servo motor for driving the mixing blades to rotate.

[0011] Preferably, a pressure gauge is provided on the grouting port.

[0012] Preferably, the feed inlet and the discharge outlet are connected by a corrugated flexible hose.

[0013] As can be seen from the above description of the present invention, compared with the prior art, the beneficial effects of the present invention are: the swing component enables the telescopic cylinder to move back and forth when pumping cement, so that the cement in the transfer chamber shakes, preventing solidification and accelerating the speed at which cement enters the feed inlet from the discharge port, thereby improving grouting efficiency.

[0014] By setting up a bidirectional hydraulic cylinder, bidirectional grouting can be performed simultaneously. When one side plunger extends, the other side plunger retracts, achieving continuous grouting and making the grouting process smoother. At the same time, the drive plate and plunger are in contact structure rather than rigid connection, which makes it easier to disassemble and maintain the equipment.

[0015] When the transfer chamber moves, the stirring paddle fixed at the discharge port remains stationary, and in turn, it stirs the slurry in the transfer chamber to prevent slurry sedimentation and improve the grouting quality. Attached Figure Description

Detailed Implementation

[0023] The present invention will be further described below through specific embodiments.

[0024] Reference Figures 1 to 6 As shown, a grouting device integrating mixing and grouting includes a base 1, a mixing chamber 2, a transfer chamber 3, a grouting mechanism 4, and a swinging mechanism 5.

[0025] The mixing chamber 2 is set on the base 1 and located at the top. The mixing chamber 2 is equipped with mixing blades 21 and a servo motor 22 for driving the mixing blades 21 to rotate. The bottom of the mixing chamber 2 is equipped with a discharge port 23 for discharging slurry. An electric control valve 24 is installed on the discharge port 23 to control the opening or closing of the discharge port 23.

[0026] The transfer chamber 3 is located below the mixing chamber 2, and the discharge port 23 extends downward into the interior of the transfer chamber 3. The bottom of the transfer chamber 3 is provided with a discharge port 31 for discharging slurry.

[0027] The grouting mechanism 4 includes a grouting chamber 41, a plunger 42, and a telescopic cylinder 43. The grouting chamber 41 has a cavity for temporarily storing liquid, with an inlet 44 and a grouting port 45 connected to its two sides. The inlet 44 is connected to the outlet 31, and the grouting port 45 communicates with the external space. The plunger 42 is sealed within the grouting chamber 41. The telescopic cylinder 43 is connected to the plunger 42 and drives it to move back and forth to pump the liquid within the grouting chamber 41. Specifically, the telescopic cylinder 43 is a bidirectional hydraulic cylinder. Two plungers are provided for the outlet 31, the plunger 42, the grouting chamber 41, and the drive plate 52. The distance between the two drive plates 52 is less than the distance between the two plungers 42. The opposing surfaces of the two drive plates 52 can contact the opposing surfaces of the plunger 42. The plunger 42 retracts to move the transfer chamber 3 in the same direction. By incorporating a bidirectional hydraulic cylinder, simultaneous bidirectional grouting is possible. When one plunger 42 extends, the other plunger 42 retracts, ensuring continuous grouting and a smoother process. Furthermore, the drive plate 52 and plunger 42 are connected via a contact structure rather than a rigid connection, facilitating disassembly and maintenance. Additionally, a hydraulic system 11 connected to the telescopic cylinder 43 is mounted on the base 1. A pressure gauge 46 is installed on the grouting port 45 for easy monitoring of grouting pressure. A drop in the pressure gauge reading indicates a blockage in the grouting mechanism 4, requiring timely maintenance.

[0028] The swing mechanism 5 includes a sliding component 51 and a drive plate 52. The sliding component 51 is connected to the transfer chamber 3, which can move back and forth via the sliding component 51. The drive plate 52 is located at the bottom of the transfer chamber 3 and is connected to the plunger 42. When the plunger 42 moves, it can push the drive plate 52 to move the transfer chamber 3 back and forth on the sliding component 51. The sliding component 51 includes a base plate 511, a limiting plate 512, a guide rail 513, and a sliding wheel 514. The base plate 511 is located above the grouting mechanism 4. The base plate 511 has a clearance groove 515 formed on it, which allows the drive plate 52 and the discharge port 31 to pass through and provides movement space. The limiting plate 512 is formed around the base plate 511 to limit the range of movement. The guide rail 513 is arranged on the base plate 511 along the extension and retraction direction of the telescopic cylinder 43. The sliding wheel 514 is located at the bottom of the transfer chamber 3 and can cooperate with the guide rail 513. Specifically, the mixing chamber 2 also includes a detachable mixing paddle 25 mounted on the discharge port 23. The mixing paddle 25 extends outward into the transfer chamber 3 and can agitate the slurry within the transfer chamber 3 as the transfer chamber 3 moves. When the transfer chamber 3 moves, the mixing paddle 25 fixed on the discharge port 23 remains stationary, indirectly agitating the slurry within the transfer chamber 3 to prevent slurry sedimentation and improve grouting quality. Furthermore, the inlet 44 and the outlet 31 are connected by a corrugated hose 47 to ensure that the inlet 44 and outlet 31 can still transport slurry when the transfer chamber 3 moves.

[0029] In use, the raw materials for the required grout are poured into the mixing chamber 2, and the mixing blades 21 are driven to rotate by the servo motor 22 for mixing. After mixing is completed, the solenoid valve is opened, and the mixed grout is conveyed from the discharge port 23 to the transfer chamber 3. After entering the transfer chamber 3, the grout enters the two side grouting chambers 41 through the discharge port 31. The telescopic cylinder 43 moves back and forth, driving the plunger 42 to move in the grouting chamber 41, pressurizing and discharging the grout from the grouting port 45 to complete the grouting. When the telescopic cylinder 43 retracts, the plunger 42 can drive the drive plate 52 to move, causing the transfer chamber 3 to move in the same direction. When the telescopic cylinder 43 reciprocates, the transfer chamber 3 moves back and forth accordingly, causing the cement in the transfer chamber 3 to shake, preventing solidification and accelerating the speed at which the cement enters the feed port 44 from the discharge port 31, thus improving the grouting efficiency. Furthermore, the stirring paddle 25 set on the discharge port 23 stirs the slurry in a variable manner as it moves in the transfer chamber 3, which avoids slurry sedimentation and improves the grouting quality, making it highly practical.

[0030] The above description is merely a preferred embodiment of the present utility model, and therefore cannot be construed as limiting the scope of the present utility model. All equivalent changes and modifications made in accordance with the scope of the patent application and the contents of the specification of the present utility model shall still fall within the scope of the patent of the present utility model.
