Description

Technical Field

[0001] This invention relates to the technical field of grouting equipment for roadbed maintenance, and specifically to a grouting equipment for roadbed maintenance. Background Technology

[0002] Roadbeds are essential in modern society. In actual construction and use, roadbed settlement risks are often encountered due to various adverse geological conditions. In daily maintenance, the mixed grout is usually injected evenly into the soil under the roadbed surface with settlement risk. The sedimentation and solidification of the grout support the roadbed and prevent settlement. However, existing grouting equipment still has problems that need to be solved.

[0003] For example, existing grouting equipment relies solely on the rotation of a mixing plate during the grout mixing process, and the grout tends to rotate synchronously with the mixing plate, which weakens the mixing effect and reduces the grout mixing efficiency. Summary of the Invention

[0067] Exemplary embodiments of the invention will now be described in more detail with reference to the accompanying drawings. While exemplary embodiments of the invention are shown in the drawings, it should be understood that the invention may be implemented in various forms and should not be limited to the embodiments set forth herein. Rather, these embodiments are provided so that this invention will be thorough and complete, and will fully convey the scope of the invention to those skilled in the art.

[0068] like Figures 1 to 9 As shown, an embodiment of the present invention provides a grouting device for roadbed maintenance, including a support frame 1, casters 2 symmetrically fixed below the support frame 1, a bottom bucket 3, a mixing bucket 5, a mixing plate 11 rotatably disposed within the mixing bucket 5, and a grouting pump 13 connected to the bottom bucket 3 via a pipeline. The output end of the grouting pump 13 is connected to a flange pipe 15, and the end of the flange pipe 15 is connected to a grouting pipe 16 via a grout delivery pipe bundle. The device also includes:

[0069] The mixing section is elastically and vertically arranged inside the mixing tank 5 and located below the mixing plate 11. It includes a pushing member arranged below the mixing plate 11 and a pushing and returning member connected to the pushing member, so as to be driven by the mixing plate 11 to agitate the slurry in the mixing tank 5 up and down.

[0070] The mixing section is provided in the bottom tank 3 and the stirring tank 5. It includes a pusher provided below the pusher and connected to the stirring tank 5, and a slurry agitator provided in the stirring tank 5. The slurry agitator is magnetically connected to the pusher to prevent the slurry in the stirring tank 5 from rotating at the same speed as the stirring plate 11 and to prevent the slurry in the bottom tank 3 from settling and solidifying.

[0071] The pusher is installed inside the mixing tank 5 and the bottom tank 3, and is sealed through the bottom of the mixing tank 5. It includes a scraper installed inside the mixing tank 5 and connected to the mixing plate 11, and a magnetic pusher sealed through the bottom of the mixing tank 5 and connected to the slurry agitator, so as to scrape off the slurry adhering to the inner wall of the mixing tank 5.

[0072] Specifically, a support plate 4 is symmetrically fixed on the bottom bucket 3, and the upper end of the support plate 4 is connected to the stirring bucket 5. Two solenoid valves 50 are symmetrically installed through the lower end of the stirring bucket 5. A protective cover 49 is fixed on the support frame 1, and the protective cover 49 is located outside the grouting pump 13. A suction pipe 12 is installed through one side of the bottom bucket 3, and the suction pipe 12 is connected to the input end of the grouting pump 13. The output end of the grouting pump 13 is connected to a branch cylinder 14, and the branch cylinder 14 is connected to a flange pipe 15.

[0073] The caster wheel 2 provides support for the support frame 1 and can rotate and roll according to the direction of the external force, so that the support frame 1 and the components above it can move together. The support frame 1 can provide support for the bottom bucket 3 through the connecting components. The bottom bucket 3 can provide stable support for the mixing bucket 5 through the support plate 4. The mixing bucket 5 can provide space for mixing the slurry used for roadbed maintenance. The solenoid valve 50 can provide a channel for the slurry in the mixing bucket 5 to enter the bottom bucket 3. By storing the slurry in the bottom bucket 3, the mixing bucket 5 can make room to continue mixing the slurry. The protective cover 49 can provide protection for the grouting pump 13 under the support of the support frame 1. The grouting pump 13 can use the suction pipe 12 to suck out the slurry in the bottom bucket 3 under the support of the support frame 1 and transport the slurry to the distribution cylinder 14. After being distributed by the distribution cylinder 14, the slurry will enter the flange pipe 15 and pass through the flange pipe 15 and the grouting pipe bundle into the grouting pipe 16. The grouting pipe 16 can be inserted into the roadbed to provide a discharge channel for the slurry.

[0074] Furthermore, a hopper 6 is provided through one side of the mixing tank 5, a bracket 7 is welded to the upper end of the mixing tank 5, a gearbox 8 is fixedly connected to the upper end of the bracket 7, a motor 9 is connected to the input end of the gearbox 8, a rotating rod 10 is connected to the output end of the gearbox 8, and the mixing plate 11 is symmetrically fixed on the outside of the rotating rod 10 and located inside the mixing tank 5.

[0075] Specifically, the mixing tank 5 provides stable support for the injection hopper 6, the injection hopper 6 provides a channel for the slurry to enter the mixing tank 5, the bracket 7 provides stable support for the gearbox 8 and the motor 9 under the support of the mixing tank 5, the gearbox 8 provides support for the rotating rod 10, so that the rotating rod 10 can support the mixing plate 11.

[0076] In practical application, workers can use the casters 2 to move the grouting equipment to the work site as needed. Then, the grouting pipe 16 is inserted into the roadbed that needs maintenance. The grout is then injected into the mixing tank 5 through the hopper 6. With the support of the bracket 7, the motor 9 is started, which drives the gearbox 8 to run. The gearbox 8 uses rotational power to rotate the rotating rod 10 clockwise at a set speed. The rotating rod 10 uses rotational power to rotate the mixing plate 11 inside the mixing tank 5, so that the mixing plate 11 can use rotational power to mix the grout in the mixing tank 5. After the grout is mixed, the workers can control the solenoid valve 50 to open, so that the mixed grout can flow from the mixing tank 5 into the bottom tank 3 through the solenoid valve 50. Then, the grouting pump 13 is started, which uses the suction pipe 12 to suck out the grout from the bottom tank 3 and inject it into the roadbed soil through the dividing cylinder 14, the grouting pipe bundle, and the grouting pipe 16. The grout solidifies after being injected into the roadbed soil to stabilize the roadbed soil.

[0077] In a preferred embodiment of the present invention, the pushing member includes:

[0078] The lower end of the stirring plate 11 is designed to be arc-shaped;

[0079] Two disturbance plates 20 are symmetrically arranged below the stirring plate 11;

[0080] The activity port 21 is opened through the disturbance plate 20;

[0081] There are two arc plates 24, which are evenly arranged on the rotation path at the lower end of the stirring plate 11.

[0082] Specifically, the lower end of the stirring plate 11 has a rounded chamfer, the disturbance plate 20 can provide space for the opening of the movable port 21, and the arc plate 24 has an arc that gradually tilts upward along the rotation path of the stirring plate 11. The stirring plate 11 can use its rounded lower end to push the arc plate 24 downward during rotation in coordination with the arc of the arc plate 24.

[0083] The reply includes:

[0084] L-plate 23, with a movable through-hole 21, one end of which is connected to arc plate 24;

[0085] The first spring 22 is symmetrically arranged on the L plate 23 and located inside the movable opening 21, and is connected to the disturbance plate 20;

[0086] Push plate 25 is fixed to the other end of L plate 23.

[0087] Specifically, the movable opening 21 can provide space for the L plate 23 to pass through and move, the disturbance plate 20 can provide support for the first spring 22, the first spring 22 is elastic and can provide support for the L plate 23, the L plate 23 can support the push plate 25 and the arc plate 24, and the push plate 25 and the arc plate 24 can disturb the slurry in the mixing tank 5 during movement.

[0088] In practical application, when the stirring plate 11 rotates clockwise, it contacts the arc plate 24 using its lower arc-shaped structure. During rotation, the stirring plate 11 repeatedly pushes the arc plate 24 downwards along its upper surface, allowing the arc plate 24 to push the L-plate 23 downwards with external force. This allows the L-plate 23 to stretch the first spring 22 downwards along the movable opening 21 under the action of external force, causing the first spring 22 to stretch and store energy. Simultaneously, this drives the push plate 25 to move downwards along with the stirring plate 11. As the mixing plate rotates, the stirring plate 11 separates from the arc plate 24. Then, the first spring 22 uses its rebound force to pull the L plate 23 upward under the support of the disturbance plate 20. This causes the L plate 23 to move upward and reset together with the arc plate 24 and the push plate 25, waiting for the next push of the stirring plate 11. This allows the arc plate 24, the L plate 23, and the push plate 25 to move up and down during the clockwise rotation of the stirring plate 11, thereby allowing the L plate 23, the arc plate 24, and the push plate 25 to disturb the slurry in the mixing tank 5, improving the efficiency of slurry mixing and molding.

[0089] In a preferred embodiment of the present invention, the derivation component includes:

[0090] Two inclined plates 26 are evenly fixed to the inner bottom wall of the mixing tank 5 and located below the push plate 25.

[0093] The guide rod 30 is located inside the through-hole 27 and moves through the guide groove 28, and is connected to the push plate 25 through a connecting component.

[0094] Specifically, a connecting plate 29 is welded above the guide rod 30, and the connecting plate 29 is connected to the push plate 25. The stirring tank 5 can provide stable support for the inclined plate 26. The inclined plate 26 has an arc and can provide opening space for the through 27 and the guide groove 28. The through 27 and the guide groove 28 can provide moving space for the guide rod 30. The guide groove 28 can provide moving guidance for the guide rod 30. The guide rod 30 can provide support for the connecting plate 29. The push plate 25 can drive the guide rod 30 to move through the connecting plate 29 under the action of external force.

[0095] The slurry disturbance components include:

[0096] Link 17 is connected to the lower end of rotating rod 10;

[0097] Turntable 18 is rotatably mounted on the outside of connecting rod 17 via bearings;

[0098] Rotary plate 19 is symmetrically fixed on the outside of turntable 18 and connected to disturbance plate 20;

[0099] The upper support rod 37 is fixed below the rotating plate 19;

[0100] The second magnet 38 is fixed to the lower end of the upper support rod 37;

[0101] The anti-sinking components are installed inside the bottom tank 3.

[0102] Specifically, the rotating rod 10 provides support for the connecting rod 17 and drives the connecting rod 17 to rotate together. The connecting rod 17 provides rotational support for the turntable 18, the turntable 18 provides support for the rotating plate 19, the rotating plate 19 provides support for the upper support rod 37, and the upper support rod 37 provides support for the second magnet 38, with the positive pole of the second magnet 38 facing downwards.

[0103] Anti-sinking components include:

[0104] The multi-stage electric rod 31 is fixed at the center of the bottom of the mixing tank 5;

[0105] The rotary disc 32 is rotatably mounted on the outside of the telescopic end of the multi-stage electric rod 31;

[0106] Side plates 33 are symmetrically fixed to the outside of the rotary table 32;

[0107] The push rod 34 is fixed to the end of the side plate 33;

[0108] The multi-stage telescopic rod 35 is fixed on the side plate 33;

[0109] The first magnet 36 is fixed to the upper end of the multi-stage telescopic rod 35 and is magnetically attracted to the second magnet 38.

[0110] Specifically, the stirring tank 5 provides stable support for the multi-stage electric rod 31, the multi-stage electric rod 31 provides rotational support for the rotating disc 32, the rotating disc 32 provides support for the side plate 33, the side plate 33 supports the push rod 34 and the multi-stage telescopic rod 35, the multi-stage telescopic rod 35 provides support for the first magnet 36, the negative pole of the first magnet 36 faces upward and is attracted to the second magnet 38, so that the rotating plate 19 can use magnetism to drive the side plate 33 and the push rod 34 to swing in the bottom tank 3 under the action of external force, and the multi-stage telescopic rod 35 can maintain its extended state by the magnetic attraction between the first magnet 36 and the second magnet 38, and the multi-stage telescopic rod 35 can retract under the action of external force.

[0111] In practical application, when the arc plate 24 is pushed downward by the stirring plate 11, it will drive the connecting plate 29 downward through the L plate 23 and the push plate 25. This allows the connecting plate 29 to press the guide rod 30 downward under the action of external force, causing the guide rod 30 to move along the guide groove 28 towards the bottom wall of the stirring tank 5 under the action of external force. At the same time, the connecting plate 29 will utilize the guiding effect of the opening 27 and cooperate with the curvature of the inclined plate 26 to swing counterclockwise around the connecting rod 17 as the center during the downward movement of the push plate 25. When the stirring plate 11 separates from the arc plate 24, the first spring 22 will use its rebound force to pull the L plate 23, the arc plate 24, and the push plate 25 upward. Under the action of external force, the push plate 25 will... The connecting plate 29 drives the guide rod 30 to move along the guide groove 28 away from the bottom wall of the mixing tank 5. At the same time, the guide effect of the opening 27 and the connecting plate 29 causes the push plate 25, L plate 23 and arc plate 24 to swing clockwise around the connecting rod 17. When the L plate 23, arc plate 24 and push plate 25 swing, the external force is transmitted to the disturbance plate 20 through the first spring 22. The disturbance plate 20 can drive the rotating plate 19 and the turntable 18 to swing together around the connecting rod 17. As the mixing plate 11 continues to rotate, the disturbance plate 20 can swing back and forth intermittently, thereby disturbing the material in the mixing tank 5 laterally and preventing the slurry in the mixing tank 5 from rotating at the same speed as the mixing plate 11, thus improving the mixing effect of the slurry.

[0112] In a preferred embodiment of the present invention, the scraping component includes:

[0113] The mixing plate 39 is fixed on the stirring plate 11 and is located outside the disturbance plate 20;

[0114] The storage trough 40 is located on the side of the mixing plate 39 near the inner wall of the mixing tank 5;

[0115] The second spring 41 is symmetrically arranged in the receiving groove 40, and one end is fixedly connected to the mixing plate 39.

[0116] The slanted scraper 42 is disposed in the storage groove 40 and is connected to the other end of the second spring 41.

[0117] Specifically, the stirring plate 11 can provide stable support for the mixing plate 39, the mixing plate 39 can provide opening space for the storage trough 40, the storage trough 40 can provide storage space for the second spring 41, the inclined scraper 42 and the third magnet 43, the second spring 41 is elastic and can use the elasticity to keep the inclined scraper 42 stored in the storage trough 40, the inclined scraper 42 has an inclined angle and the end near the inner wall of the stirring tank 5 is sharp.

[0118] The magnetic actuator includes:

[0119] The third magnet 43 is fixed to the side of the inclined scraper 42 near the second spring 41;

[0120] A ring-shaped magnet 46 is installed through the bottom wall of the mixing tank 5;

[0121] The sealing ring 47 is fixedly connected through the bottom wall of the mixing tank 5 and is attached to the annular magnet 46;

[0122] The push-connecting part is located below the annular magnet 46.

[0123] Specifically, the inclined scraper 42 provides stable support for the third magnet 43. The positive pole of the third magnet 43 faces away from the inclined scraper 42. The upper part of the ring magnet 46 is the positive pole. It can use the principle of like poles repulsion to push the third magnet 43 towards the inner wall of the stirring tank 5. This allows the third magnet 43 to use magnetic force to push the inclined scraper 42 to move and stretch the second spring 41. The stirring tank 5 provides stable support for the sealing ring 47. The sealing ring 47 and the ring magnet 46 work together to achieve a sealing effect. The ring magnet 46 can push the sealing ring 47 to produce a slight deformation under the action of external force, so that the ring magnet 46 can move up and down through the sealing ring 47 under the action of external force.

[0124] The push-connecting parts include:

[0125] Connecting plate 44 is connected to the upper end of push rod 34;

[0126] Arc-T plate 45 is fixed to the upper end of connecting plate 44;

[0127] T-groove 48 is formed at the lower end of annular magnet 46;

[0128] The arc-shaped T-plate 45 is located inside the T-ring groove 48.

[0129] Specifically, the push rod 34 can provide stable support for the connecting plate 44, the connecting plate 44 can provide support for the arc T plate 45, the ring magnet 46 can provide opening space for the T-ring groove 48, the T-ring groove 48 can provide moving space for the arc T plate 45, and they work together to push the ring magnet 46 up and down under the action of external force.

[0130] When the push rod 34 swings, it will drive the arc T plate 45 to rotate along the T-ring groove 48 with the multi-stage electric rod 31 as the center through the connecting plate 44.

[0131] In practical application, the operator can control the retraction of the multi-stage electric rod 31 according to actual needs. The multi-stage electric rod 31 uses its telescopic end to pull the rotating disc 32 and side plate 33 upwards. This causes the side plate 33 to drive the pusher rod 34 and the multi-stage telescopic rod 35 upwards together. Simultaneously, the first magnet 36 will adhere to the bottom wall of the mixing drum 5 using the magnetic force of the second magnet 38. As the multi-stage electric rod 31 continues to retract, the rotating disc 32 and side plate 33 will continuously push the multi-stage telescopic rod 35 under external force. This allows the multi-stage telescopic rod 35 to retract under the influence of external force and the resistance of the mixing drum 5 and the first magnet 36. At the same time, the side plate 33 will drive the pusher rod 34 upwards to adjust its height under external force. The pusher rod 34 will also drive the connecting plate 44 upwards, which in turn will drive the arc-T plate 45 upwards. The two plates move together, causing the arc-shaped plate 45 to push the annular magnet 46 through the sealing ring 47 and move upward under the action of external force. This allows the upper part of the annular magnet 46 to move between the disturbance plate 20 and the mixing plate 39. At this time, the annular magnet 46 will use its own magnetic force to push the third magnet 43 to move away from the connecting rod 17. At the same time, the third magnet 43 will use its magnetic force to push the inclined scraper 42 to move together, causing the inclined scraper 42 to stretch the second spring 41 and move out of the receiving groove 40. The scraper 42 will then use its sharp end to stick to the inner wall of the mixing tank 5. Simultaneously, the motor 9 is started, causing the rotating rod 10 to drive the mixing plate 39 to rotate together through the mixing plate 11. The mixing plate 39 can then drive the inclined scraper 42 to rotate together through the second spring 41. This allows the inclined scraper 42 to use rotational power and tilt angle to scrape off the slurry adhering to the inner wall of the mixing tank 5, preventing waste.

It should be noted that those skilled in the art can make various improvements and modifications without departing from the principles of the present invention, and these improvements and modifications should also be considered within the scope of protection of the present invention.
