Description

Technical Field

[0001] This utility model relates to the field of engineering equipment technology, and more specifically, to a backfill soil reinforcement and compaction device. Background Technology

[0002] The backfill soil reinforcement compaction device is an engineering machine that uses impact or vibration energy to compact backfill soil. Its core working principle is to squeeze out the air and moisture between soil particles through the free fall or high-frequency vibration of the hammer, thereby reducing the void ratio and significantly improving the compaction, bearing capacity and anti-settlement stability of the soil. This device is a key piece of equipment in backfilling projects such as building foundations, roadbeds, and pipeline trenches to ensure project quality and prevent uneven settlement in the later stages.

[0003] For example, Chinese patent publication: A backfill compaction device for civil engineering, application number: CN202023016272.0, includes an integrated box, with a protective cover fixedly connected to the lower end of the integrated box. Both the integrated box and the protective cover have working chambers inside. A cylinder is fixedly installed inside the protective cover. A tamping rod is movably connected to the lower end of the cylinder. An injection anchor rod is movably connected to the lower end of the tamping rod. An injection hole is opened on the outer side of the tamping rod. A tamping panel is fixedly connected to the lower end of the tamping rod. A dust baffle is fixedly connected to the upper front side of the tamping panel. Spring hinges are movably connected to the left and right sides of the tamping panel. Rollers are movably connected to the outer side of the spring hinges. A connection port is opened at the upper end of the tamping panel. In this backfill compaction device for civil engineering, the lower pressure plate can be folded by a locking hinge to reduce the size of the equipment. Simultaneously, when operating, the worker can stabilize the equipment by grasping the slot and pressing the lower pressure plate downwards, avoiding frequent vibrations that make the equipment inconvenient to handle.

[0004] However, in the above-mentioned technical solutions, the common compaction devices on the market, such as vibratory plate compactors, mainly rely on the operator's experience and visual inspection to judge the landing position of the compaction plate and the overlap relationship with the previous compaction area. Manual visual inspection is prone to deviation, resulting in compaction blind spots (missed compaction) or repeated compaction, making it difficult to guarantee the uniformity of compaction and directly affecting the quality of the project. Utility Model Content

[0005] The main purpose of this utility model is to provide a backfill soil reinforcement compaction device, which can effectively solve the problems in the background art.

[0006] To achieve the above objectives, the technical solution adopted by this utility model is as follows: a backfill soil reinforcement compaction device, comprising a base and a pressure plate disposed on the bottom surface of the base, two handles fixedly installed on both sides of the base, a connecting seat fixedly disposed on one outer wall of the bottom surface of the base, a rotating assembly that can rotate around an axis disposed on the base, a crosshair laser positioning instrument mounted on the rotating assembly, four first pointers respectively corresponding to the four corner positions of the pressure plate on the bottom surface of the base, and a second pointer on the bottom surface of the rotating assembly. By rotating the rotating assembly, the second pointer is aligned with any one of the first pointers, thereby making the projection of the crosshair laser line emitted by the crosshair laser positioning instrument coincide with the outer contour of the corresponding corner of the pressure plate.

[0007] Preferably, the bottom surface of the connecting seat is connected to the pressure plate through a number of sets of elastic buffer mechanisms. Each set of elastic buffer mechanisms includes a first connecting post fixed to the connecting seat, a second connecting post slidably sleeved outside the first connecting post, and a spring sleeved outside the second connecting post. The bottom end of the second connecting post is fixed to the pressure plate, and the two ends of the spring abut against the first connecting post and the pressure plate, respectively.

[0008] Preferably, a vibration motor is installed on the pressure plate.

[0009] Preferably, the rotating assembly includes a rotating ring rotatably mounted on the base, a worm gear fixedly mounted on the rotating ring, a worm meshing with one side of the worm gear, and a rotating column extending out of the base fixed at one end of the worm.

[0010] Preferably, a rotating handle is fixedly provided at one end of the rotating column located outside the base.

[0011] Preferably, the crosshair laser positioning instrument and the second pointer are both disposed on the rotating ring.

[0012] Compared with the prior art, the present invention has the following beneficial effects:

[0013] (1) This utility model drives the worm gear mechanism by rotating the handle, which drives the crosshair laser positioning device on the rotating ring to rotate, so that it can quickly switch to the target corner of the pressure plate. The second pointer is aligned with the first pointer to achieve precise positioning. At this time, the crosshair laser positioning device is exactly above the corner, and the crosshair laser line projected onto the ground coincides with the outer contour of the corner of the pressure plate, thus providing a precise visual positioning benchmark. This fundamentally solves the technical problems of inaccurate positioning, complicated operation and missed compaction of traditional tamping devices, and improves the compaction uniformity and work efficiency.

[0018] The technical solutions of this utility model will be clearly and completely described below with reference to the embodiments of this utility model. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of this utility model.

[0019] like Figure 1 and Figure 2 As shown, a backfill soil reinforcement compaction device includes a base 1 and a pressure plate 11 disposed on the bottom surface of the base 1. Two handles 2 are fixedly installed on both sides of the base 1. A connecting seat 7 is fixedly disposed on the outer wall of one side of the bottom surface of the base 1. A rotating assembly 3 that can rotate around an axis is disposed on the base 1. A crosshair laser positioning instrument 4 is installed on the rotating assembly 3. The bottom surface of the base 1 is provided with four first pointers 6 corresponding to the four corner positions of the pressure plate 11. The bottom surface of the rotating assembly 3 is provided with a second pointer 5. By rotating the rotating assembly 3, the second pointer 5 is aligned with any one of the first pointers 6, thereby making the projection of the crosshair laser line emitted by the crosshair laser positioning instrument 4 coincide with the outer contour of the corresponding corner of the pressure plate 11.

[0020] The bottom surface of the connecting seat 7 is connected to the pressure plate 11 through several sets of elastic buffer mechanisms. Each set of elastic buffer mechanisms includes a first connecting post 8 fixed to the connecting seat 7, a second connecting post 9 slidably sleeved outside the first connecting post 8, and a spring 10 sleeved outside the second connecting post 9. The bottom end of the second connecting post 9 is fixed to the pressure plate 11, and the two ends of the spring 10 abut against the first connecting post 8 and the pressure plate 11 respectively.

[0021] A vibration motor 12 is installed on the pressure plate 11.

[0022] like Figure 3 As shown, in another embodiment of the present invention, the rotating assembly 3 includes a rotating ring 301 rotatably disposed on the base 1, a worm gear 302 fixedly disposed on the rotating ring 301, a worm 303 meshing on one side of the worm gear 302, and a rotating column 304 extending out of the base 1 fixed at one end of the worm 303.

[0023] A rotating handle 305 is fixedly provided at one end of the rotating column 304 located outside the base 1;

[0024] When different corners of the pressure plate 11 need to be positioned, the operator rotates the rotating handle 305 located outside the base 1, causing the rotating column 304 and worm gear 303 fixedly connected to it to rotate synchronously. The worm gear 303 drives the worm wheel 302 meshing with it to rotate. Since the worm wheel 302 is fixedly installed on the rotating ring 301, it drives the entire rotating ring 301 to rotate. The crosshair laser positioning instrument 4 and the second index 5 fixed on the rotating ring 301 rotate synchronously. At the same time, the inherent self-locking characteristic of the worm gear transmission mechanism effectively prevents the rotating ring 301 from accidentally shifting under the impact vibration condition.

[0025] The working principle of this backfill soil reinforcement compaction device:

[0026] During use, the operator moves the device to the work area by holding handle 2. If positioning of a specific corner of the pressure plate 11 is required, the operator rotates handle 305, causing the rotating column 304 and worm gear 303 to rotate, which in turn drives the worm wheel 302 and the fixed rotating ring 301 to rotate. During this process, the operator observes the second indicator 5 at the bottom of the rotating ring 301. When it aligns with the first indicator 6 on the base 1 corresponding to the target corner, the operator stops rotating. At this time, the crosshair laser positioning device 4 is exactly above the corner, and the crosshair laser line projected onto the ground coincides with the outer contour of the corner of the pressure plate 11, thus providing a precise visual positioning reference. This allows a single crosshair laser positioning device 4 to achieve accurate positioning. It can quickly switch to four working positions as needed, and then start the vibration motor 12 to perform tamping. The resulting impact vibration is effectively absorbed and isolated by the elastic buffer mechanism composed of spring 10, first connecting column 8 and second connecting column 9. After completing the operation at this point, the laser positioning device can be quickly switched to the next target corner by turning the handle 305. The above process is repeated to avoid missed tamping or repeated tamping, and to ensure the uniformity of the tamped material. It effectively solves the problems of inaccurate positioning and complicated operation of traditional tamping devices.

[0027] Obviously, the above embodiments of this utility model are merely examples for clearly illustrating the present invention, and are not intended to limit the implementation of the present invention. For those skilled in the art, other variations or modifications can be made based on the above description. It is impossible to exhaustively list all the implementation methods here. All obvious variations or modifications derived from the technical solutions of the present invention are still within the protection scope of the present invention.
