Description

Technical Field

[0001] This utility model belongs to the field of foundation compaction technology, and in particular relates to a foundation compaction device with compaction angle adjustment function. Background Technology

[0002] In the field of construction engineering, the stability of the foundation plays a decisive role in the safety and durability of the entire building. With the rapid development of the construction industry, the requirements for foundation treatment are also increasing.

[0003] Existing technology, such as Chinese Patent Publication No. CN221480770U, discloses a foundation compactor, belonging to the field of building construction, to solve the problem of inconvenient switching between transfer and tamping operations of the compactor. The compactor includes a frame; deflection wheel frames are internally hinged at both ends of the frame, with connecting axles at the bottom of the deflection wheel frames. Coaxial traveling wheels are rotatably connected to the left and right ends of the connecting axles. An adjustment shaft is rotatably connected to the top of the deflection wheel frames, with a double-ended screw threaded into the adjustment shaft. A compaction base is slidably connected to the bottom of the frame, and a compaction motor is fixedly installed at the top center of the compaction base. Protective covers are fixedly installed on both sides of the compaction motor. This foundation compactor, by controlling the adjustment shaft through the double-ended screw, can achieve deflection operations of the deflection wheel frames in different directions, enabling the transfer and tamping operations of the compactor. This improves the ease of use of the compactor and increases the efficiency of site transfer.

[0004] Existing foundation compaction machines can usually only compact the foundation at a fixed angle. When faced with complex geological conditions, such as sloping foundations or areas requiring special compaction angles, they cannot flexibly adjust the compaction angle, resulting in unsatisfactory compaction effects. This can easily lead to localized loosening or over-compaction of the foundation, affecting the overall structural stability. Utility Model Content

[0005] The purpose of this utility model is to provide a foundation compaction device with a compaction angle adjustment function, so as to solve the technical problem mentioned in the background art that the existing foundation compaction machine can usually only compact the foundation at a fixed angle, and cannot flexibly adjust the compaction angle, resulting in unsatisfactory compaction effect, easy to cause local loosening or over-compaction of the foundation, thereby affecting the overall structural stability.

[0006] To achieve the above objectives, the specific technical solution of this utility model is as follows: A foundation compaction device with a compaction angle adjustment function includes a fixed frame, and a compaction mechanism is provided inside the fixed frame. The compaction mechanism includes a hydraulic cylinder, a movable block, a rotating seat, a guide frame, and a fixed seat. The output end of the hydraulic cylinder is fixedly connected to the movable block, the guide frame is slidably connected to the inner side of the fixed frame, the fixed seat is fixedly connected to the bottom of the movable block, and the rotating seat is rotatably connected to the fixed seat.

[0007] A rammer, which is fixedly installed at the bottom of a rotating base;

[0008] An adjustment mechanism is provided on the movable block. The adjustment mechanism includes pressure rollers movably disposed on both sides of the movable block, and the pressure rollers abut against the upper end of the rotating seat.

[0009] Preferably, the hydraulic cylinder is fixedly installed inside the upper part of the fixing frame, and an arc-shaped guide groove is provided on the outer circumferential surface of the fixing seat.

[0010] Preferably, an arc-shaped guide rail is fixedly connected to the inner wall of the rotating seat, and the arc-shaped guide rail is slidably connected to the arc-shaped guide groove.

[0011] Preferably, a gear is rotatably connected inside the movable block, and a motor is fixedly installed on one side of the movable block.

[0012] Preferably, a worm is fixedly connected to the output end of the motor, and a worm wheel is meshed with one side of the worm.

[0013] Preferably, the worm gear and the gear are coaxially and fixedly connected.

[0014] Preferably, the movable block is fixedly connected to both the upper and lower ends on both sides, and a limit rod is fixedly connected to the fixed block.

[0016] Preferably, the lifting frame has limit grooves at both the upper and lower ends, and the limit rod is movably connected in the limit groove.

[0017] Preferably, the pressure roller is rotatably connected to the bottom of the lifting frame.

[0018] The foundation compaction device with adjustable compaction angle according to this utility model has the following advantages:

[0019] 1. The foundation compaction device with compaction angle adjustment function uses a pressure roller on one side to press down and a pressure roller on the other side to move up, causing the rotating seat to rotate relative to the fixed seat, which in turn drives the hammer at the bottom to rotate, thereby realizing the adjustment of the compaction angle. After the angle adjustment is completed, the hydraulic cylinder is started to drive the hammer to move, so that the hammer can compact the foundation at the adjusted angle.

[0020] 2. Through the cooperation of a series of transmission components such as motor, worm, worm wheel, gear and rack, the position of the pressure roller can be precisely controlled, thereby accurately adjusting the compaction angle of the tamping hammer. This meets the diverse needs of various complex working conditions and different construction standards for the compaction angle of the foundation, ensuring the high-quality completion of the foundation compaction operation.

[0021] 3. The adjustable compaction angle allows the tamping hammer to compact the foundation from multiple angles, avoiding problems such as uneven local stress and incomplete compaction that may occur with fixed-angle compaction. This ensures that the entire foundation receives relatively uniform compaction treatment in all parts, effectively improving the overall density and bearing capacity of the foundation, and laying a solid foundation for subsequent building construction.

[0036] The following disclosure provides many different implementations or examples for different structures of the embodiments of the present invention. To simplify the disclosure of the embodiments of the present invention, specific examples of components and arrangements are described below. Of course, these are merely examples and are not intended to limit the embodiments of the present invention.

[0037] To better understand the purpose, structure, and function of this utility model, the following description, in conjunction with the accompanying drawings, provides a more detailed account of a foundation compaction device with adjustable compaction angle.

[0038] like Figures 1-8 As shown, the present invention provides a foundation compaction device with an adjustable compaction angle, comprising a fixed frame 1, a compaction mechanism 3 inside the fixed frame 1, the compaction mechanism 3 comprising a hydraulic cylinder 31, a movable block 32, a rotating seat 33, a guide frame 34 and a fixed seat 35, the output end of the hydraulic cylinder 31 being fixedly connected to the movable block 32, the guide frame 34 being slidably connected to the inner side of the fixed frame 1, the fixed seat 35 being fixedly connected to the bottom of the movable block 32, and the rotating seat 33 being rotatably connected to the fixed seat 35;

[0039] Hammer 4 is fixedly installed at the bottom of rotating seat 33;

[0040] Adjustment mechanism 2 is set on movable block 32. Adjustment mechanism 2 includes pressure rollers 27 movably set on both sides of movable block 32. Pressure rollers 27 abut against the upper end of rotating seat 33.

[0041] In this application, the hydraulic cylinder 31 pushes the movable block 32 to move up and down along the inner side of the fixed frame 1, and the fixed seat 35, rotating seat 33 and ramming hammer 4 at the bottom move accordingly. The ramming hammer 4 compacts the foundation. When it is necessary to adjust the ramming angle of the ramming hammer 4, it is achieved by adjusting the adjustment mechanism 2. By changing the force of the pressure roller 27 on the rotating seat 33, the rotating seat 33 rotates relative to the fixed seat 35, thereby driving the ramming hammer 4 to change the angle. Then, under the drive of the hydraulic cylinder 31, the ramming hammer 4 can compact the foundation at different angles.

[0042] The tamping angle of the tamping hammer 4 can be easily changed by adjusting the mechanism 2 to adapt to different terrains and tamping requirements for foundation construction. For example, in sloping foundations or areas requiring special tamping angles, the angle of the tamping hammer 4 can be precisely adjusted to improve the tamping effect and quality and ensure the stability of the foundation.

[0043] The hydraulic cylinder 31 is fixedly installed inside the upper part of the fixed frame 1. An arc-shaped guide groove 36 is provided on the outer circumferential surface of the fixed seat 35. An arc-shaped guide rail 37 is fixedly connected to the inner wall of the rotating seat 33. The arc-shaped guide rail 37 and the arc-shaped guide groove 36 are slidably connected.

[0044] In specific settings, a pointer is provided on the bottom side of the fixed seat 35, and a scale is provided on the same side of the rotating seat 33 as the pointer. The angle change of the hammer 4 can be accurately grasped according to the pointer and scale indication, improving the accuracy of adjustment. By setting the arc-shaped guide rail 37 and the arc-shaped guide groove 36, the stability of the connection between the rotating seat 33 and the fixed seat 35 can be improved, ensuring that the rotating seat 33 moves along the specific trajectory of the fixed seat 35.

[0045] The movable block 32 is internally connected to a gear 24. A motor 21 is fixedly installed on one side of the movable block 32. A worm gear 22 is fixedly connected to the output end of the motor 21. A worm wheel 23 is meshed with one side of the worm gear 22. The worm wheel 23 is coaxially fixedly connected to the gear 24. Fixed blocks 210 are fixedly connected to both the upper and lower ends of both sides of the movable block 32. Limiting rods 29 are fixedly connected to the fixed blocks 210. A rack 28 is meshed with both sides of the gear 24. A lifting frame 25 is fixedly connected to one side of the rack 28. Limiting grooves 26 are opened at both the upper and lower ends of the lifting frame 25. The limiting rod 29 is movably connected in the limiting groove 26. The pressure roller 27 is rotatably connected to the bottom of the lifting frame 25.

[0046] In this application, when it is necessary to adjust the compaction angle of the tamping hammer 4, the motor 21 is started to drive the worm 22 to rotate. Since the worm 22 and the worm wheel 23 mesh with each other, the worm wheel 23 rotates and drives the gear 24 to rotate synchronously. The gear 24 drives the racks 28 on both sides to move up and down respectively, and the lifting frames 25 on both sides also move up and down accordingly. By setting a limiting groove 26 on the lifting frame 25 that matches the limiting rod 29, the limiting rod 29 is movably connected in the limiting groove 26. Therefore, the lifting frame 25 moves up and down in a straight line along the limiting rod 29, ensuring the accuracy of its movement direction.

[0047] The pressure roller 27 moves synchronously with the lifting frame 25. One side of the pressure roller 27 presses down while the other side of the pressure roller 27 moves up, causing the rotating seat 33 to rotate relative to the fixed seat 35. This, in turn, drives the bottom hammer 4 to rotate, thereby adjusting the compaction angle. After the angle adjustment is completed, the hydraulic cylinder 31 is activated to move the hammer 4, so that the hammer 4 can compact the foundation at the adjusted angle.

[0048] Through the cooperation of a series of transmission components such as motor 21, worm 22, worm wheel 23, gear 24 and rack 28, the position of the pressure roller 27 can be precisely controlled, thereby accurately adjusting the compaction angle of the tamping hammer 4. This meets the diverse needs for the compaction angle of the foundation under various complex working conditions and different construction standards, ensuring the high-quality completion of the foundation compaction operation.

[0049] The adjustable compaction angle allows the tamping hammer 4 to compact the foundation from multiple angles, avoiding problems such as uneven local stress and inadequate compaction that may occur with fixed-angle compaction. This ensures that the entire foundation receives relatively uniform compaction treatment in all parts, effectively improving the overall density and bearing capacity of the foundation, and laying a solid foundation for subsequent building construction.

[0050] Working principle of a foundation compaction device with adjustable compaction angle:

[0051] When the compaction angle needs to be adjusted, the motor 21 is started to drive the worm gear 22 and worm wheel 23 to rotate, causing the gear 24 to rotate synchronously. The gear 24 drives the racks 28 on both sides to move up and down respectively. The lifting frames 25 on both sides move up and down in a straight line along the limit rod 29. The pressure roller 27 moves synchronously with the lifting frame 25. One pressure roller 27 presses down and the other pressure roller 27 moves up, causing the rotating seat 33 to rotate relative to the fixed seat 35, which in turn drives the bottom hammer 4 to rotate, thereby realizing the adjustment of the compaction angle. After the angle adjustment is completed, the hydraulic cylinder 31 is started to drive the hammer 4 to move, so that the hammer 4 can compact the foundation at the adjusted angle.

[0052] It is understood that this utility model has been described through some embodiments, and those skilled in the art will recognize that various changes or equivalent substitutions can be made to these features and embodiments without departing from the spirit and scope of this utility model. Furthermore, under the teachings of this utility model, these features and embodiments can be modified to adapt to specific situations and materials without departing from the spirit and scope of this utility model. Therefore, this utility model is not limited to the specific embodiments disclosed herein, and all embodiments falling within the scope of the claims of this application are within the protection scope of this utility model.
