Description

Technical Field

[0001] This utility model relates to the field of building engineering technology, and in particular to a compaction device for building foundations. Background Technology

[0002] The foundation of a building is a core component of the underground structure of a building. Its core function is to transfer all the loads from the superstructure (such as walls, floors, roofs, etc.). The construction of the foundation needs to be based on geological conditions (such as soft soil, sand, rock layers) and design schemes (such as replacement foundation, pile foundation, composite foundation, etc.). The core work is completed with the help of compaction devices, such as using a dynamic compaction machine to compact loose soil layers to improve the bearing capacity of the foundation.

[0003] However, since the lifting height of the hammer of the dynamic compaction machine is fixed, it cannot be flexibly adjusted according to the actual thickness and density difference of the loose soil layer. When the falling position is constrained by the minimum limit, if the soil layer is thick and loose in some areas, the impact energy at the fixed height may not be enough to compact the soil layer to the density required by the design, resulting in insufficient local bearing capacity of the foundation.

[0004] Therefore, those skilled in the art have provided a compaction device for the foundation of building projects to solve the problems mentioned in the background art. Utility Model Content

[0005] The purpose of this utility model is to address the shortcomings of existing technologies by proposing a compaction device for building foundations. When in use, this device is driven by a servo motor to rotate a screw, which in turn moves a threaded mounting frame up and down along a storage groove, allowing for flexible adjustment of the compaction height. The height of the compaction block can be controlled according to the looseness of the foundation soil and the required compaction depth, ensuring effective compaction. In conjunction with a rotary motor driving a rocker arm to rotate, and with the sliding of a slider, the compaction block can be stably driven for compaction operations.

[0006] To achieve the above objectives, the present invention provides the following technical solution: A compaction device for building foundations includes a mobile vehicle. A mounting rod is fixedly connected to the front end of the upper surface of the mobile vehicle. A storage slot is opened at the front end of the mounting rod. A servo motor is fixedly connected to the bottom of the storage slot. A screw is fixedly connected to the output end of the servo motor. A threaded mounting bracket is threadedly connected to the outer wall of the screw. Rockers are provided on both sides of the upper end of the inner wall of the threaded mounting bracket. A slider is rotatably connected to the lower end of the outer wall of the adjacent side of the rockers. A pressure block is fixedly connected to the lower end of the slider.

[0007] Compared with existing compaction devices for building foundations, this compaction device for building foundations uses a servo motor to drive the screw to rotate, which in turn moves the threaded mounting frame up and down along the storage groove, allowing for flexible adjustment of the compaction height. It can control the height of the compaction block according to the looseness of the foundation soil and the required compaction depth, ensuring the compaction effect. In conjunction with the rotary motor driving the rocker arm to rotate, and with the sliding of the slider, it can stably drive the compaction block to perform the compaction operation.

[0008] Furthermore, a counterweight is fixedly connected to the rear end of the upper surface of the mobile vehicle; Through the above technical solution, the counterweight can effectively balance the overall weight distribution of the device. When the threaded mounting bracket at the front of the device drives the pressure block to perform the tamping operation, it will generate a downward impact force, which can easily cause the front of the mobile vehicle to sink and the rear to tilt upward. The counterweight can increase the pressure on the rear of the mobile vehicle by its own weight, thus preventing the device from tipping over or shifting its position due to force imbalance.

[0009] Furthermore, the threaded mounting bracket is slidably connected to the inner wall of the storage slot; The above technical solution allows for easy adjustment of the required compaction depth by using a threaded mounting bracket that slides along the inner wall of the storage tank.

[0010] Furthermore, a mounting shell is fixedly connected to the upper end of the outer wall of one side of the threaded mounting bracket, and a rotary motor is fixedly connected to the inner wall of the mounting shell. The output end of the rotary motor passes through the threaded mounting bracket and is fixedly connected to the outer wall of one side rocker arm. The above technical solution allows the rotary motor to easily drive the rocker arm on one side to rotate.

[0011] Furthermore, the outer wall of the rocker arm on the other side is rotatably connected to the upper end of the inner wall on the other side of the threaded mounting bracket; The above technical solution, through the rocker arm on the other side, facilitates the improvement of its rotational stability.

[0012] Furthermore, limit blocks are fixedly connected to both sides of the outer wall of the slider, and limit grooves are opened in the middle of the inner wall of the threaded mounting bracket, with the limit blocks slidingly connected to the inner wall of the limit grooves respectively. With the above technical solution, the slider can be limited to reciprocate by the limiting blocks slidingly connected to the inner wall of the limiting groove.

[0013] This utility model has the following beneficial effects: This utility model proposes a compaction device for building foundations. Compared with existing compaction devices for building foundations, this device is driven by a servo motor to rotate a screw, which can move a threaded mounting frame up and down along the storage groove, enabling flexible adjustment of the compaction height. It can control the height of the compaction block according to the looseness of the foundation soil and the required compaction depth, ensuring the compaction effect. In conjunction with a rotary motor driving a rocker arm to rotate, and with the sliding of the slider, it can stably drive the compaction block to perform the compaction operation.

[0016] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of specific embodiments. Obviously, the described specific embodiments are only a part of the specific embodiments of the present invention, and not all of them. Based on the specific embodiments of the present invention, all other specific embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0017] Reference Figure 1-5An embodiment of this utility model provides a compaction device for the foundation of a building project, comprising a mobile vehicle 1, a mounting support rod 12 fixedly connected to the front end of the upper surface of the mobile vehicle 1, a storage groove 13 opened at the front end of the mounting support rod 12, a servo motor 14 fixedly connected to the bottom of the storage groove 13, a screw 15 fixedly connected to the output end of the servo motor 14, a threaded mounting bracket 2 threadedly connected to the outer wall of the screw 15, rocker arms 23 provided on both sides of the upper end of the inner wall of the threaded mounting bracket 2, a slider 24 rotatably connected to the lower end of the outer wall of the adjacent side of the rocker arms 23, and a pressure block 25 fixedly connected to the lower end of the slider 24.

[0018] Compared with existing compaction devices for building foundations, this compaction device for building foundations uses a servo motor 14 to drive the screw 15 to rotate, which can drive the threaded mounting bracket 2 to move up and down along the storage groove 13, so as to flexibly adjust the compaction height. It can control the height of the compaction block 25 according to the looseness of the foundation soil and the compaction depth requirements, ensuring the compaction effect. With the help of the rotary motor 22 to drive the rocker arm 23 to rotate, and with the sliding of the slider 24, it can stably drive the compaction block 25 to perform the compaction operation.

[0019] A counterweight 11 is fixedly connected to the rear end of the upper surface of the mobile vehicle 1; The counterweight 11 can effectively balance the overall weight distribution of the device. When the threaded mounting bracket 2 at the front end of the device drives the pressure block 25 to perform a tamping operation, it will generate a downward impact force, which can easily cause the front end of the mobile vehicle 1 to sink and the rear end to tilt upward. The counterweight 11 can increase the pressure on the rear end of the mobile vehicle 1 by its own weight, so as to prevent the device from tipping over or shifting its position due to force imbalance.

[0020] The threaded mounting bracket 2 is slidably connected to the inner wall of the storage slot 13; The threaded mounting bracket 2 slides on the inner wall of the storage groove 13, which facilitates changing the required compaction depth.

[0021] A mounting shell 21 is fixedly connected to the upper end of the outer wall of one side of the threaded mounting bracket 2. A rotary motor 22 is fixedly connected to the inner wall of the mounting shell 21. The output end of the rotary motor 22 passes through the threaded mounting bracket 2 and is fixedly connected to the outer wall of the rocker arm 23 on one side. The rotary motor 22 facilitates the rotation of the rocker arm 23 on one side.

[0022] The outer wall of the other rocker arm 23 is rotatably connected to the upper end of the inner wall of the other side of the threaded mounting bracket 2; The rocker arm 23 on the other side facilitates improved stability of its rotation.

[0023] Limiting blocks 27 are fixedly connected to both sides of the outer wall of the slider 24, and limiting grooves 26 are opened in the middle of the inner wall of the threaded mounting bracket 2. The limiting blocks 27 are slidably connected to the inner wall of the limiting grooves 26 respectively. By having the limiting blocks 27 slidably connected to the inner wall of the limiting groove 26, the slider 24 can be limited to make it reciprocate.

[0024] Working principle: First, the device is moved to the foundation compaction point by the mobile vehicle 1. Then, the external controller starts the servo motor 14. The output of the servo motor 14 drives the screw 15 to rotate. Since the threaded mounting bracket 2 is threadedly connected to the screw 15 and slides on the inner wall of the storage groove 13, the rotation of the screw 15 is converted into the up and down movement of the threaded mounting bracket 2 along the storage groove 13. In this way, the height of the threaded mounting bracket 2 and the components below it is adjusted according to the looseness of the foundation soil and the compaction depth requirements. After the height adjustment is completed, the rotary motor 22 is started to drive the rocker arm 23 on one side to rotate. The rocker arm 23 on the other side is rotatably connected to the inner wall of the threaded mounting bracket 2 on the other side. The two rocker arms 23 are synchronously linked and drive the slider 24 connected to the lower end to move. At the same time, the limiting blocks 27 on both sides of the slider 24 slide along the limiting grooves 26 on the inner wall of the threaded mounting bracket 2, limiting the movement trajectory of the slider 24 and ensuring its stable vertical reciprocating motion. Finally, the pressure block 25 at the lower end of the slider 24 is pressed. Complete the compaction of the foundation. The following points should be noted in this document: 1. The accompanying drawings of the embodiments disclosed herein only relate to the structures involved in the embodiments disclosed herein; other structures can be referred to in general design.
