Abstract
Description
Technical Field
[0001] This utility model relates to the field of foundation treatment technology, specifically a device for treating collapsible loess foundations. Background Technology
[0002] The purpose of treating collapsible loess foundations is mainly to eliminate the collapsibility of loess and improve the bearing capacity of the foundation. Commonly used foundation treatment methods include: soil or lime-soil cushion layer, soil piles or lime-soil piles, dynamic compaction, heavy hammer compaction, pile foundation, pre-soaking method, etc. The treatment methods for each type of foundation should be adapted to local conditions.
[0003] In response, existing technology patent publication number CN221972335U discloses a device for treating collapsible loess foundations. This device includes a base, movable wheels at the bottom of the base, and mounting blocks on the outside of the base. A fixing frame is fixedly connected to the top of the base, and a dual-axis motor is fixedly connected to the bottom of the fixing frame. Connecting components are provided at both ends of the dual-axis motor. A rope-retracting shaft is provided on one side of the connecting components, and a clamping component is provided on the outside of the rope-retracting shaft. Electric push rods are fixedly connected to both sides of the fixing frame, and a guide rod is provided inside the base. The collapsible loess foundation treatment device provided by this utility model solves the problems of existing devices in actual use. Due to the heavy weight of the compaction hammer, the motor shaft is only clamped by a ring-shaped clamping plate, resulting in poor fixation and difficulty in stably lifting the compaction hammer. Furthermore, the compaction hammer lacks a guiding structure, causing it to deviate when falling after being lifted, making it inconvenient to use.
[0004] However, in actual use, when the tamping hammer is compacting the foundation downwards, there is no limit to the upward and downward movement trajectory of the tamping hammer. As a result, the position of the tamping hammer will deviate when it moves downwards. At the same time, the wire rope is not limited during the up and down winding process, which will cause the compaction position of the tamping hammer to be adjusted. Therefore, improving and perfecting the above-mentioned problems has become an urgent issue to be solved. Utility Model Content
[0005] The purpose of this utility model is to provide a treatment device for collapsible loess foundations, in order to solve the problems mentioned in the background art, where the tamping hammer does not limit the vertical movement trajectory of the tamping hammer when it tamps the foundation downwards, resulting in the position of the tamping hammer shifting downwards. At the same time, the wire rope is not limited during the up and down winding process, which leads to the adjustment of the tamping position of the tamping hammer.
[0006] To achieve the above objectives, this utility model provides the following technical solution: a collapsible loess foundation treatment device, including a mounting frame, a guide component installed on the lower surface of the mounting frame, and limit components installed on both sides of the inner wall of the mounting frame;
[0007] The guide assembly includes a fixing rod, which is mounted on the lower surface of the mounting frame. A top plate is mounted on the end of the fixing rod away from the mounting frame. A stabilizing ring is mounted on the outer surface of the top plate. An installation groove is formed inside the stabilizing ring. A guide cylinder is installed inside the installation groove. A guide post is slidably mounted inside the guide cylinder. A tamping hammer is fixedly connected to the lower end of the guide post.
[0008] Preferably, a drive motor is installed on both the front and rear surfaces of the mounting bracket, and a rotating column is installed through the output end of the drive motor inside the mounting bracket.
[0009] Preferably, a receiving roller is fixedly connected to the front end of the rotating column, and a steel wire rope is installed on the outer surface of the receiving roller.
[0010] Preferably, the lower end of the wire rope is fixedly connected to a connecting post, and the lower end of the connecting post is fixedly connected to a first connecting hook.
[0011] Preferably, a second connecting hook is installed on the upper surface of the tamping hammer. The second connecting hook has the same structure as the first connecting hook and the installation positions are symmetrical to each other.
[0012] Preferably, the limiting component includes a connecting strip, which is mounted on the inner wall of the mounting frame, and a mounting ring is mounted on the end of the connecting strip away from the mounting frame.
[0013] Preferably, a limiting cylinder is installed inside the mounting ring, and auxiliary rollers are evenly installed on the inner sidewall of the limiting cylinder.
[0014] Compared with the prior art, the beneficial effects of this utility model are:
[0015] 1. In use, this collapsible loess foundation treatment device first fixes the top plate with a fixing rod. The guide cylinder is fixedly installed inside the installation groove. When the compaction hammer moves up and down, it drives the guide column to move up and down. Then, the guide column moves up and down inside the guide cylinder. The guide cylinder limits the movement trajectory of the guide column, thereby limiting the movement trajectory of the compaction hammer. This solves the problem of no guide for the compaction hammer in the past. As a result, the compaction hammer is more accurate in compacting the collapsible loess foundation, and the position of the compaction hammer will not deviate. The overall guiding effect is better. Subsequently, the drive motor is started to drive the rotating column to rotate, which in turn drives the receiving roller to rotate. The rotation of the receiving roller can wind the wire rope around the outer surface of the receiving roller. Then, the wire rope drives the connecting column to rise. The connecting column is fixedly connected to the first connecting hook. That is, when the wire rope is wound around the surface of the receiving roller, it can drive the compaction hammer to rise as a whole. Conversely, the compaction hammer descends to compact the collapsible loess foundation.
[0016] 2. In use, when the compaction hammer moves downwards, the wire rope moves downwards inside the limiting cylinder. The limiting cylinder limits the position of the wire rope, thus preventing it from swaying during its descent. Furthermore, the auxiliary rollers on the inner wall of the limiting cylinder both abut and assist its downward movement, further preventing swaying during the hammer's descent. The connecting strip limits the positions of the mounting ring and the limiting cylinder, resulting in good overall stability. This device, through its limiting components, limits the movement trajectory of the wire rope and also assists its movement. Attached Figure Description

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0024] Please see Figures 1-5 One embodiment provided by this utility model:
[0025] A collapsible loess foundation treatment device. The drive motors 9 used in this application are all products that can be directly purchased on the market. Their principles and connection methods are existing technologies known to those skilled in the art, so they will not be described in detail here. It includes a mounting frame 1. A guide component is installed on the lower surface of the mounting frame 1, and limit components are installed on both sides of the inner wall of the mounting frame 1.
[0026] The guiding assembly includes a fixing rod 2, which is installed on the lower surface of the mounting frame 1. A top plate 3 is installed on the end of the fixing rod 2 away from the mounting frame 1. A stabilizing ring 4 is installed on the outer surface of the top plate 3. An installation groove 5 is opened inside the stabilizing ring 4. A guide cylinder 6 is installed inside the installation groove 5. A guide column 7 is slidably installed inside the guide cylinder 6. A compaction hammer 8 is fixedly connected to the lower end of the guide column 7. The top plate 3 is fixed by the fixing rod 2. By fixing the guide cylinder 6 inside the installation groove 5, when the compaction hammer 8 moves up and down, it will drive the guide column 7 to move up and down. At this time, the guide column 7 will move up and down inside the guide cylinder 6. The movement trajectory of the guide column 7 is limited by the setting of the guide cylinder 6, thereby limiting the movement trajectory of the compaction hammer 8. This solves the problem of no guidance for the compaction hammer 8 in the past. As a result, the compaction hammer 8 is more accurate in the compaction process of collapsible loess foundation. The position of the compaction hammer 8 will not be deviated, and the overall guiding effect is better.
[0027] The front and rear surfaces of the mounting frame 1 are equipped with drive motors 9. The output end of the drive motor 9 passes through the interior of the mounting frame 1 and is equipped with a rotating column 10. The front end of the rotating column 10 is fixedly connected to a receiving roller 11. A steel wire rope 12 is installed on the outer surface of the receiving roller 11. By starting the drive motor 9, the rotating column 10 can be driven to rotate, thereby the rotating column 10 can drive the receiving roller 11 to rotate. The rotation of the receiving roller 11 can wind the steel wire rope 12 around the outer surface of the receiving roller 11. Then the steel wire rope 12 will drive the connecting column 13 to rise, and the connecting column 13 is fixedly connected to the first connecting hook 14. That is, when the steel wire rope 12 is wound around the surface of the receiving roller 11, it can drive the tamping hammer 8 to rise as a whole. Conversely, the tamping hammer 8 descends to perform tamping operation on the collapsible loess foundation.
[0028] A connecting post 13 is fixedly connected to the lower end of the wire rope 12, and a first connecting hook 14 is fixedly connected to the lower end of the connecting post 13. A second connecting hook 15 is installed on the upper surface of the tamping hammer 8. The second connecting hook 15 has the same structure as the first connecting hook 14, and their installation positions are symmetrical. The first connecting hook 14 has the same structure as the second connecting hook 15, and the top surface of the second connecting hook 15 is provided with both the connecting post 13 and the wire rope 12.
[0029] The limiting component includes a connecting strip 18, which is installed on the inner wall of the mounting frame 1. An mounting ring 17 is installed at the end of the connecting strip 18 away from the mounting frame 1. A limiting cylinder 16 is installed inside the mounting ring 17. Auxiliary rollers 19 are evenly installed on the inner side wall of the limiting cylinder 16. When the tamping hammer 8 moves downwards, the wire rope 12 moves downwards inside the limiting cylinder 16. The limiting cylinder 16 limits the position of the wire rope 12, preventing it from swaying during its descent. The auxiliary rollers 19 on the inner wall of the limiting cylinder 16 both abut and limit the limiting cylinder 16, and assist it in moving downwards, further preventing swaying during the descent of the tamping hammer 8. The connecting strip 18 limits the positions of the mounting ring 17 and the limiting cylinder 16, resulting in good overall stability. This setting limits the movement trajectory of the wire rope 12 and also assists its movement.
[0030] Working Principle: When using this device, the operator first connects it to an external power source to provide electrical support. The top plate 3 is then fixed using the fixing rod 2. The guide cylinder 6 is fixedly installed inside the mounting groove 5. When the compaction hammer 8 moves up and down, it drives the guide column 7 to move up and down. The guide column 7 then moves up and down inside the guide cylinder 6. The guide cylinder 6 limits the movement trajectory of the guide column 7, thus limiting the movement trajectory of the compaction hammer 8. This solves the problem of not having a guide for the compaction hammer 8, allowing the compaction hammer 8 to effectively compact collapsible loess foundations. The actual process is quite accurate. The position of the tamping hammer 8 does not shift, and the overall guiding effect is good. Subsequently, by starting the drive motor 9, the rotating column 10 can be driven to rotate, which in turn drives the collecting roller 11 to rotate. The rotation of the collecting roller 11 can wind the wire rope 12 around the outer surface of the collecting roller 11. Then the wire rope 12 will drive the connecting column 13 to rise, and the connecting column 13 is fixedly connected to the first connecting hook 14. That is, when the wire rope 12 is wound around the surface of the collecting roller 11, it can drive the tamping hammer 8 to rise as a whole. Conversely, the tamping hammer 8 descends to tampe the collapsible loess foundation.
[0031] When the tamping hammer 8 moves downward, the wire rope 12 will move downward inside the limiting cylinder 16. The limiting cylinder 16 can limit the position of the wire rope 12, thereby preventing the wire rope 12 from shaking during the downward process. The auxiliary roller 19 on the inner wall of the limiting cylinder 16 not only abuts and limits the limiting cylinder 16, but also assists the limiting cylinder 16 in moving downward, which can prevent the tamping hammer 8 from shaking during the descent. The connecting strip 18 can limit the position of the mounting ring 17 and the limiting cylinder 16. The above is the working principle of this utility model.
[0032] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model in any way. Those skilled in the art can readily implement this utility model based on the accompanying drawings and the above description. However, any modifications, alterations, or equivalent variations made by those skilled in the art without departing from the scope of the utility model's technical solution, utilizing the disclosed technical content, are considered equivalent embodiments of this utility model. Furthermore, any equivalent changes, alterations, or variations made to the above embodiments based on the essential technology of this utility model are still within the protection scope of this utility model's technical solution.
