Description

Technical Field

[0001] This invention relates to the field of compaction equipment technology, and in particular to an automatic slope trimming device for foundation pits. Background Technology

[0002] The finishing work on the slope of the excavated foundation pit can effectively control soil deformation, avoid accidents such as slope instability and collapse caused by unreasonable slope or uneven surface, protect the safety of construction personnel and surrounding facilities, and provide a good working surface for subsequent construction (such as steel bar installation, formwork support, and concrete pouring). It also reduces stress concentration caused by uneven surface, ensures uniform stress on the structure, and improves the overall quality. Therefore, after the foundation pit is excavated, it is often necessary to carry out corresponding finishing work on its slope.

[0003] Current slope trimming work is often done manually by construction workers. This method is relatively inefficient, and because it involves manual point-to-point trimming with shovels and other tools, inconsistencies often arise between adjacent areas, making it impossible to guarantee the relative flatness of the slope and affecting subsequent work. Furthermore, since the slope is a sloping plane, workers standing on it need to contend with instability, greatly increasing the inconvenience of the work and making it easy to slip and fall, resulting in relatively low safety. Summary of the Invention

[0004] The purpose of this invention is to solve the problems in the background art by proposing an automatic slope trimming device for foundation pits.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] An automatic slope trimming device for foundation pits includes a connecting box, a connecting toothed belt slidably connected to the top of the connecting box, the connecting toothed belt sliding through the connecting box, the two ends of the connecting toothed belt being used to fix the upper and lower ends of the foundation pit, a servo motor being installed inside the connecting box, guide wheels being fixedly connected to both ends of the servo motor, a rotating wheel being belt-driven above one of the guide wheels, two rotating teeth being symmetrically rotatably connected inside the connecting box, the two rotating teeth being fixedly connected to each other, one rotating tooth being fixedly connected to the rotating wheel, and the two rotating teeth engaging with the bottom of the connecting toothed belt; the device also includes:

[0007] A rolling mechanism is located at the bottom of the connecting box and is used to roll and compact the soil layer on the slope of the foundation pit.

[0008] A leveling mechanism is provided at the bottom of the connecting box and is located on one side of the rolling mechanism. The leveling mechanism is used to level the soil layer after it has been compacted by the rolling mechanism.

[0009] The compaction mechanism is located at the bottom of the connecting box and is situated on the side of the leveling mechanism away from the rolling mechanism. The compaction mechanism is used to compact the slope of the foundation pit.

[0010] And a differential mechanism, which is rotatably connected inside the connecting box, and is used to drive the compaction mechanism to rotate.

[0011] In the aforementioned automatic slope trimming device for foundation pits, the rolling mechanism includes two pressure rollers, two connecting wheels, and a connecting plate. The connecting plate is fixedly connected to the bottom of the connecting box. One connecting wheel is rotatably connected to the inside of the connecting box, and the other connecting wheel is rotatably connected to the inside of the connecting plate. The two pressure rollers are symmetrically rotatably connected to both sides of the bottom of the connecting plate. The surfaces of the two pressure rollers on opposite sides are fixedly connected to both sides of the connecting wheel located below. The two connecting wheels are connected by belt drive.

[0012] In the aforementioned automatic slope trimming device for foundation pits, the leveling mechanism includes a scraper, two material distribution columns, and two intermediate wheels. The scraper is fixedly connected to the bottom of the connecting box. The two material distribution columns are symmetrically rotatably connected to the inside of the scraper. One of the intermediate wheels is rotatably connected to the inside of the scraper, and the surfaces of the two material distribution columns on opposite sides are fixedly connected to the two sides of the intermediate wheel. The other intermediate wheel is rotatably connected to the inside of the connecting box. The two intermediate wheels are connected by belt drive.

[0013] In the aforementioned automatic slope trimming device for foundation pits, the compaction mechanism includes a compaction box, two compaction plates, and two turntables. The compaction box is fixedly connected to one side of the bottom of a connecting box. The two compaction plates are symmetrically slidably connected to both sides inside the compaction box. The two turntables are symmetrically rotated and connected to both sides inside the compaction box. A top rod is hinged to the top of the compaction plate, and the other end of the top rod is hinged to the surface of the turntable. A transmission wheel is fixedly connected between the two turntables. An guide wheel is connected above the transmission wheel via a belt drive, and the guide wheel is rotatably connected to the inside of the connecting box.

[0014] In the aforementioned automatic slope trimming device for foundation pits, the differential mechanism includes a bevel tooth, a disc tooth, and a differential tooth. The bevel tooth is fixedly connected to one side of the surface of the guide wheel, the disc tooth is rotatably connected to the inside of the connecting box, and the disc tooth meshes with the bevel tooth. The differential tooth is rotatably connected to the inside of the connecting box, and the differential tooth meshes with one side of the top of the disc tooth. The diameter of the differential tooth is larger than the diameter of the disc tooth, and the diameter of the disc tooth is the same as the diameter of the bevel tooth.

[0015] In the aforementioned automatic slope trimming device for foundation pits, a linkage wheel is fixedly connected to one side of the differential gear, and a mating wheel is fixedly connected to the same side of the connecting wheel and the intermediate wheel located inside the connecting box. The two mating wheels are connected by belt drive, and the mating wheel located on one side of the surface of the intermediate wheel is connected to the linkage wheel by belt drive. The guide wheel located at the other end of the servo motor is connected to the mating wheel located on the surface of the connecting wheel by belt drive.

[0016] In the aforementioned automatic slope trimming device for foundation pits, a cover plate is fixedly connected to the bottom of the connecting box. The cover plate is located above the pressure roller, and a scraper is fixedly connected to one side of the inner wall of the cover plate. The scraper is slidably connected to one side of the surface of the pressure roller.

[0017] Compared with existing technologies, the advantages of this automatic slope trimming device for foundation pits are:

[0018] 1. The soil layer on the slope is initially rolled by the pressure roller along the direction of the connecting box, and the more protruding parts are scraped and leveled by the scraping mechanism. The excess soil is dispersed and discharged through the material distribution column. This can realize the automatic preliminary compaction and leveling work and ensure that the amount of trimming in the area is consistent.

[0019] 2. The differential mechanism drives the pulley to rotate, and the two turntables drive the top rod to move quickly inside the tamping box. This causes the two tamping plates to impact rapidly up and down in the tamping box. The tamping box compacts the soil layer on the slope, which can ensure the repair effect. The problem of unsatisfactory effect and low safety of manual compaction by surface workers exists.

[0020] In summary, this invention uses a pressure roller to initially compact the soil layer on the slope along the direction of movement of the connecting box, and a scraping mechanism to scrape and level the more protruding parts. Excess soil is dispersed and discharged through the material distribution column. This can achieve automatic initial compaction and leveling work, ensuring the consistency of the amount of compaction within the area. The differential speed mechanism drives the guide wheel to rotate, and two turntables drive the top rod to move rapidly inside the tamping box, thereby driving two tamping plates to rapidly impact up and down in the tamping box. The tamping box compacts the soil layer on the slope, ensuring the finishing effect and avoiding the problems of unsatisfactory results and low safety of manual compaction by surface workers.

[0029] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

They are only for the convenience of describing this invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this invention.

[0031] Reference Figures 1-7 An automatic slope trimming device for foundation pits includes a connecting box 1, a connecting toothed belt 2 slidably connected to the top of the connecting box 1, the connecting toothed belt 2 sliding through the connecting box 1, the two ends of the connecting toothed belt 2 being used to fix the upper and lower ends of the foundation pit, a servo motor 3 being installed inside the connecting box 1, guide wheels 4 being fixedly connected to both ends of the servo motor 3, a rotating wheel 5 being belt-driven connected above one of the guide wheels 4, two rotating teeth 6 being symmetrically rotatably connected inside the connecting box 1, the two rotating teeth 6 being fixedly connected to each other, one rotating tooth 6 being fixedly connected to the rotating wheel 5, and the two rotating teeth 6 meshing with the bottom of the connecting toothed belt 2; and also includes:

[0032] A rolling mechanism 7 is located at the bottom of the connecting box 1. The rolling mechanism 7 is used to compact the soil layer on the slope of the foundation pit. The rolling mechanism 7 includes two pressure rollers 701, two connecting wheels 702, and a connecting plate 703. The connecting plate 703 is fixedly connected to the bottom of the connecting box 1. One connecting wheel 702 is rotatably connected to the inside of the connecting box 1, and the other connecting wheel 702 is rotatably connected to the inside of the connecting plate 703. The two pressure rollers 701 are symmetrically rotatably connected to both sides of the bottom of the connecting plate 703. The surfaces of the two pressure rollers 701 on opposite sides are respectively connected to the soil layer on the bottom of the connecting plate 703. The two sides of the lower connecting wheel 702 are fixedly connected, and the two connecting wheels 702 are connected by belt drive. The bottom of the connecting box 1 is fixedly connected to the cover plate 16, which is located above the pressure roller 701. A scraper 17 is fixedly connected to one side of the inner wall of the cover plate 16. The scraper 17 is slidably connected to one side of the surface of the pressure roller 701. The connecting wheel 702 and the intermediate wheel 803 located inside the connecting box 1 are both fixedly connected to the same side of the connecting wheel 702 and the intermediate wheel 803. The guide wheel 4 located at the other end of the servo motor 3 is connected to the mating wheel 15 located on the surface of the connecting wheel 702 by belt drive.

[0033] In this process, by fixing the two ends of the connecting toothed belt 2 to the bottom of the pit and the top of the slope respectively, the meshing effect between the rotating teeth 6 and the connecting toothed belt 2 can drive the connecting box 1 to move along the connecting toothed belt 2 from the bottom of the pit to the top of the slope during the rotation of the servo motor 3. At this time, one of the guide wheels 4 will drive a connecting wheel 702 located inside the connecting box 1 to rotate through the mating wheel 15, and drive the two pressure rollers 701 to rotate synchronously through the connecting wheel 702 below it. During the movement of the connecting box 1, the pressure rollers 701 can perform preliminary compaction and trimming of the loose soil layer on the slope. During the rotation of the pressure rollers 701, the scraper 17 can scrape the surface of the pressure rollers 701 to prevent excessive soil from adhering to the surface of the pressure rollers 701 and affecting its contact effect with the soil layer.

[0034] A leveling mechanism 8 is located at the bottom of the connecting box 1 and on one side of the rolling mechanism 7. The leveling mechanism 8 is used to level the soil layer after it has been compacted by the rolling mechanism 7. The leveling mechanism 8 includes a scraper 801, two material distribution columns 802 and two intermediate wheels 803. The scraper 801 is fixedly connected to the bottom of the connecting box 1. The two material distribution columns 802 are symmetrically rotatably connected to the inside of the scraper 801. One of the intermediate wheels 803 is rotatably connected to the inside of the scraper 801, and the surfaces of the two material distribution columns 802 on opposite sides are respectively fixedly connected to the two sides of the intermediate wheel 803. The other intermediate wheel 803 is rotatably connected to the inside of the connecting box 1. The two intermediate wheels 803 are connected by belt drive. The connecting wheel 702 and the intermediate wheel 803 inside the connecting box 1 are both fixedly connected to the same side of the connecting wheel 702 and the intermediate wheel 803. The two mating wheels 15 are connected by belt drive.

[0035] In this process, while the servo motor 3 drives the connecting wheel 702 to rotate, the transmission effect between the two mating wheels 15 drives the intermediate wheel 803 located inside the connecting box 1 to rotate. Since the upper and lower intermediate wheels 803 are connected by belt transmission, the upper intermediate wheel 803 drives the two material distribution columns 802 to rotate synchronously through the lower intermediate wheel 803. During the movement of the connecting box 1, the scraper 801 can slide along the slope to scrape the soil that is protruding on the slope. Excess soil will enter the interior of the scraper 801 and be discharged outward through the two rotating material distribution columns 802, which can achieve the scraping of the slope and ensure the uniformity of the trimming.

[0036] The compaction mechanism 9 is located at the bottom of the connecting box 1 and is situated on the side of the leveling mechanism 8 away from the rolling mechanism 7. The compaction mechanism 9 is used to compact the slope of the foundation pit. It includes a compaction box 901, two compaction plates 902, and two turntables 903. The compaction box 901 is fixedly connected to one side of the bottom of the connecting box 1. The two compaction plates 902 are symmetrically slidably connected to both sides inside the compaction box 901. The two turntables 903 are symmetrically rotated and connected to both sides inside the compaction box 901. A top rod 11 is hinged to the top of each compaction plate 902, and the other end of the top rod 11 is hinged to the surface of the turntable 903. A transmission wheel 12 is fixedly connected between the two turntables 903, and a guide wheel is connected above the transmission wheel 12 via a belt drive. 13. The pull wheel 13 is rotatably connected to the inside of the connecting box 1. The differential mechanism 10 is rotatably connected to the inside of the connecting box 1. The differential mechanism 10 is used to drive the compaction mechanism 9 to rotate. The differential mechanism 10 includes a bevel tooth 101, a disc tooth 102 and a differential tooth 103. The bevel tooth 101 is fixedly connected to one side of the surface of the pull wheel 13. The disc tooth 102 is rotatably connected to the inside of the connecting box 1 and meshes with the bevel tooth 101. The differential tooth 103 is rotatably connected to the inside of the connecting box 1 and meshes with one side of the top of the disc tooth 102. The diameter of the differential tooth 103 is larger than the diameter of the disc tooth 102. The diameter of the disc tooth 102 is the same as the diameter of the bevel tooth 101. A linkage wheel 14 is fixedly connected to one side of the differential tooth 103.

[0037] In this process, the rotation of the gear 15 drives the linkage gear 14 to rotate synchronously. At this time, the differential gear 103 drives the disc gear 102 to rotate, which in turn drives the bevel gear 101 to rotate. Since the diameter of the differential gear 103 is larger than the diameter of the disc gear 102 and the bevel gear 101, the differential gear 103 can ensure that the rotational speed of the disc gear 102 and the bevel gear 101 is greater than that of the differential gear 103 when it drives the disc gear 102 to rotate. At this time, the bevel gear 101 drives the transmission wheel 12 to rotate through the pull wheel 13, which can drive the two turntables 903 to rotate rapidly on both sides inside the tamping box 901. Through the hinge effect between the turntable and the top rod 11, the two tamping plates 902 can move up and down rapidly inside the tamping box 901 and create an impact effect on the bottom of the inner wall of the tamping box 901. This forces the tamping box 901 to tamp the soil on the slope, further ensuring the compaction effect of the slope and ensuring the overall finishing effect.

[0038] The following is a detailed explanation of the specific working principle and usage of the invention: In use, the first step is to fix the two ends of the connecting toothed belt 2 to the bottom of the pit and the top of the slope, respectively. Through the meshing effect between the rotating teeth 6 and the connecting toothed belt 2, the connecting box 1 can be moved along the connecting toothed belt 2 from the bottom of the pit to the top of the slope during the rotation of the servo motor 3. At this time, one of the guide wheels 4 will drive a connecting wheel 702 located inside the connecting box 1 to rotate through the mating wheel 15. The connecting wheel 702 below it will drive the two pressure rollers 701 to rotate synchronously. During the movement of the connecting box 1, the pressure rollers 701 will perform preliminary compaction and trimming of the loose soil layer on the slope. During the rotation of the pressure rollers 701, the scraper 17 will scrape the surface of the pressure rollers 701 to prevent excessive soil from adhering to the surface of the pressure rollers 701 and affecting its contact effect with the soil layer.

[0039] In the second step, while the servo motor 3 drives the connecting wheel 702 to rotate, it will drive the intermediate wheel 803 located inside the connecting box 1 to rotate through the transmission effect between the two mating wheels 15. Since the upper and lower intermediate wheels 803 are connected by belt transmission, the upper intermediate wheel 803 will drive the two material distribution columns 802 to rotate synchronously through the lower intermediate wheel 803. During the movement of the connecting box 1, the scraper 801 can slide along the slope to scrape the soil that is more protruding on the slope. Excess soil will enter the interior of the scraper 801 and be discharged outward through the two rotating material distribution columns 802, which can achieve the scraping of the slope and ensure the uniformity of the trimming.

[0040] The third step involves rotating the coupling wheel 15, which in turn drives the linkage wheel 14 to rotate synchronously. At this time, the differential gear 103 drives the disc gear 102 to rotate, which in turn drives the bevel gear 101 to rotate. Since the diameter of the differential gear 103 is larger than the diameters of the disc gear 102 and the bevel gear 101, the differential gear 103 can ensure that the rotational speeds of the disc gear 102 and the bevel gear 101 are greater than those of the differential gear 103 when it drives the disc gear 102 to rotate. The bevel gear 101 then drives the transmission wheel 12 to rotate through the guide wheel 13, which in turn drives the two turntables 903 to rotate rapidly on both sides inside the compaction box 901. Through the hinge effect with the top rod 11, the two compaction plates 902 can move up and down rapidly inside the compaction box 901, creating an impact effect on the bottom of the inner wall of the compaction box 901. This forces the compaction box 901 to compact the soil on the slope, further ensuring the compaction effect of the slope and the overall finishing effect.

[0041] To further clarify, the aforementioned fixed connection should be interpreted broadly unless otherwise explicitly specified and limited. For example, it may be welding, gluing, or integral molding, or other conventional methods well known to those skilled in the art.

[0042] The above description is only a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
