Description

Technical Field

[0001] The present application relates to the technical field of foundation pit backfilling, and in particular to a backfill soil transportation device. Background Art

[0002] During construction, many foundation pits are dug at the construction site. The main function of the foundation pit is to provide a space for the foundation masonry work to be carried out according to the designated location of the design. After the building foundation is built in the foundation pit, the surrounding area of the foundation pit is exposed, which may have an adverse effect on the stability and durability of the building foundation itself. Therefore, after the building foundation construction is completed, the foundation pit needs to be backfilled in a timely manner.

[0003] Currently, the main method for backfilling foundation pits is to directly dump soil into the pit using earthmoving equipment such as sand trucks or bulldozers, followed by manual paving. However, some construction sites are limited, and the distance between adjacent foundation pits is small, resulting in narrow roads between adjacent pits. In such cases, large equipment such as sand trucks and bulldozers cannot pass through the edge of the pit, so backfilling the pit must be done entirely by manpower.

[0004] Regarding the above-mentioned related technologies, there are the following defects: backfilling the foundation pit beside the narrow road by manpower is slow and consumes a lot of labor, which needs to be further improved. Summary of the Invention

[0005] In order to improve the time-consuming and labor-intensive problem of manually backfilling soil into foundation pits beside narrow roads, the present application provides a backfill soil transportation device.

[0006] This application provides a backfill soil transportation device, which adopts the following technical solution:

[0008] By adopting the above technical solution, the base plate is installed on the top of the foundation pit using the installation assembly. When the foundation pit is backfilled, soil is loaded into the soil loading box, and then the driving mechanism drives the soil loading box to slide back and forth on the base plate. When the unloading hole on the soil loading box is aligned with the drop opening, the soil in the soil loading box is evenly filled into the foundation pit, effectively realizing the backfill construction of the foundation pit next to a narrow road. The operation is convenient, manpower is effectively saved, and the construction efficiency is high.

[0009] Optionally, a plurality of soil loading boxes are provided, and the plurality of soil loading boxes rotate and reciprocate in sequence around the length direction of the base plate, and the distance between the end of the base plate and the existing building is not less than the height of the soil loading box.

[0010] By adopting the above technical solution, multiple soil loading boxes are used and the soil loading boxes are rotated on the bottom plate, so that the multiple soil loading boxes can continuously backfill soil into the foundation pit, effectively speeding up construction efficiency.

[0012] By adopting the above technical solution, the soil loading box is fixedly connected to the chain, and the power component is used to drive the sprocket to rotate, so that the chain can operate effectively. When the chain is running, the soil loading box can realize rotary reciprocating motion around the bottom plate. The structure is simple and easy to use.

[0013] Optionally, the power assembly includes a rotating rod and a power member, the rotating rod is horizontally arranged on the base plate along the width direction of the base plate, and both ends of the rotating rod pass through the base plate and are fixedly connected to the sprockets opposite to each other on both sides of the base plate, and the power member is used to drive any of the rotating rods to rotate.

[0014] By adopting the above technical solution, the sprockets on both sides of the base plate are connected by a rotating rod, so that the two sprockets are effectively connected. When a power part is used to drive any rotating rod to rotate, multiple sprockets are further driven by the chain to operate synchronously, thereby realizing the driving of the soil loading box. The structure is simple and labor-saving.

[0015] Optionally, the soil loading box is rotatably connected to a connecting rod near the side of the chain, and the connecting rod is fixedly connected to any link of the chain.

[0016] By adopting the above technical solution, the soil loading box is connected to the chain using a connecting rod, so that the soil loading box and the chain are convenient to connect and the structure is stable.

[0017] Optionally, support plates are provided on both sides of the base plate, the connecting rod is horizontally arranged on the top of the support plate, and a support slider is fixedly provided at the position where the connecting rod passes through the support plate, and a sliding groove is provided on the top of the support plate for the support slider to slide.

[0018] By adopting the above technical solution, the support slider is slidably connected in the sliding groove, so that when the soil loading box rotates on the base plate, the support slider and the support plate effectively improve the supporting effect on the soil loading box, so that the support plate effectively shares the load on the chain, reduces the possibility of chain breakage, and the trimming chain operates normally with a stable structure.

[0019] Optionally, the mounting assembly includes a mounting plate overlapped on the top of the foundation pit, a bracket vertically arranged on the mounting plate, and a fixing member arranged on the mounting plate for fixing the mounting plate to the top of the foundation pit, the base plate is connected to the bracket, the length direction of the base plate is perpendicular to the length direction of the mounting plate, and the distance between the base plate and the mounting plate is not less than the height of the soil loading box.

[0020] By adopting the above technical solution, when installing the base plate, the mounting plate is fixed to the top of the foundation pit by the fixing parts. The mounting plate can be fixed by overlapping the two ends with the foundation pit, or by fixing one end with the top of the foundation pit. The base plate is connected to the bracket, so that the mounting plate can effectively support and fix the base plate to the top of the foundation pit. The mounting plate will not interfere with the operation of the soil loading box. The fixation of the mounting plate can be selected according to the construction situation, and it has high practical value.

[0021] Optionally, the fixing member includes fixing rods provided on both sides of the mounting plate in the width direction, and the mounting plate is provided with fixing holes for the fixing rods to pass through.

[0022] By adopting the above technical solution, the mounting plate is fixed with fixing parts.

[0023] Optionally, anti-wear pads are provided on both side surfaces in the width direction of the mounting plate.

[0024] By adopting the above technical solution, when one end of the mounting plate is fixed to the top of the foundation pit, the anti-wear pad abuts against the building foundation in the foundation pit, thereby effectively strengthening the connection of the mounting plate and improving the operational stability of the soil loading box.

[0025] Optionally, a screw is rotatably connected to the mounting plate along the length direction, the screw is threadedly connected to the bracket, and a limiting groove is provided on the mounting plate for the bracket to slide.

DETAILED DESCRIPTION

[0038] The following is combined with Figure 1-6 This application is described in further detail.

[0039] The embodiment of the present application discloses a backfill soil transportation device, referring to Figure 1 and Figure 2 , including a bottom plate 2 installed on the top of the foundation pit 1, a soil loading box 3 slidably connected to the bottom plate 2, and a mounting assembly 4 provided on the bottom plate 2 for mounting the bottom plate 2 on the foundation pit 1. Figure 3 and Figure 4 In this embodiment, due to the limited construction site, foundation pit 1 may be adjacent to multiple foundation pits 1 or other building foundations 10, resulting in a relatively narrow roadway adjacent to the excavated foundation pit 1. To facilitate backfilling of the foundation pit 1, a soil loading box 3 is provided that slides back and forth on the base plate 2. The bottom of the soil loading box 3 is in contact with the base plate 2, and a discharge hole 30 is formed at the bottom of the soil loading box 3. The base plate 2 is evenly distributed with multiple discharge ports 20 that match the discharge holes 30. A drive mechanism 5 is provided on the base plate 2 for driving the soil loading box 3 to slide.

[0040] During construction, the base plate 2 is connected to the top of the foundation pit 1 via the mounting assembly 4. Earth is then loaded into the soil loading box 3 using equipment such as an excavator or bulldozer from the side away from the narrow road of the foundation pit 1. In other embodiments, construction workers can also load earth into the soil loading box 3 by standing on either side of the base plate 2. Once earth is in the soil loading box 3, the drive mechanism 5 drives the soil loading box 3 to slide back and forth on the base plate 2. When the discharge hole 30 aligns with the drop opening 20, the earth in the soil loading box 3 falls into the foundation pit 1, thereby gradually filling the foundation pit 1 with earth and evenly spreading the earth, effectively backfilling the foundation pit 1, saving manpower, and improving construction efficiency.

[0041] Reference Figure 3 and Figure 4In this embodiment, to further improve soil filling efficiency, multiple soil loading boxes 3 are provided. These boxes 3 rotate and reciprocate in sequence along the length of the base plate 2. The distance between the widthwise end of the base plate 2 and the existing building is no less than the height of the boxes 3. The existing building comprises a foundation pit 1 and a building foundation 10 built within the pit 1. Therefore, as the multiple soil loading boxes 3 rotate and reciprocate on the base plate 2, neither the sidewalls of the pit 1 nor the building foundation 10 within the pit 1 interfere with their operation. Furthermore, the multiple soil loading boxes 3 continuously add soil to the pit 1, effectively accelerating soil filling efficiency. Furthermore, because the backfill soil in the pit 1 is highly viscous and may adhere to the inner walls of the boxes 3, when the boxes 3 reach the bottom of the base plate 2, the soil in the boxes 3 can be completely poured into the pit 1, reducing soil adhesion and reducing backfill efficiency, thereby accelerating construction progress.

[0042] Reference Figure 3 and Figure 5 In this embodiment, the drive mechanism 5 includes a chain 50, a sprocket 51, and a power assembly 52. The chain 50 is looped around both sides of the base plate 2. The sprockets 51 are rotatably connected to both sides of the base plate 2 and are located at the ends of the base plate 2. The sprockets 51 on the same side of the base plate 2 mesh with the chain 50, so that the sprockets 51 serve as the driving wheel and the driven wheel for driving the chain 50. The power assembly 52 is further provided on the base plate 2 to drive the multiple sprockets 51 to operate synchronously. The soil loading box 3 is fixedly connected to the two chains 50 on the base plate 2.

[0043] Therefore, when the power assembly 52 drives the multiple sprockets 51, the chain 50 is effectively driven to rotate. At this time, driven by the chain 50, the soil loading box 3 effectively slides on the base plate 2, completing the backfilling of the foundation pit 1. In order to increase the sliding stability of the soil loading box 3 and the base plate 2, a sliding ball 6 is slidably connected between the soil loading box 3 and the abutment plate. The base plate 2 is provided with a guide groove 60 for the sliding of the sliding ball 6. The sliding ball 6 not only increases the connection stability of the base plate 2 within the soil loading box 3, but also serves as a guide for the soil loading box 3, reducing the sliding friction between the soil loading box 3 and the base plate 2. The sliding of the soil loading box 3 is stable and the structure is reliable.

[0044] Reference Figure 3 and Figure 5In this embodiment, the power assembly 52 includes a rotating rod 520 and a power member. The rotating rod 520 is horizontally arranged on the base plate 2 along the width direction of the base plate 2. The two ends of the rotating rod 520 pass through the base plate 2 and are fixedly connected to the sprockets 51 on opposite sides of the base plate 2. The power member is used to drive any of the rotating rods 520 to rotate. In this embodiment, the power member is configured as a servo motor 521, a worm gear 522, and a worm 523. The worm gear 522 is fixedly mounted on either end of any rotating rod 520 that passes through the base plate 2, and the worm gear 522 is located inside the sprocket 51. The servo motor 521 is connected to the side of the base plate 2 via the mounting plate 40. The output end of the servo motor 521 is fixedly connected to the rod portion of the worm 523, and the tooth segment of the worm 523 meshes with the worm gear 522. Thus, when the servo motor 521 is activated, the worm gear 522 and the worm 523 can be effectively driven to rotate, causing any rotating rod 520 to also rotate. Then, under the synchronous operation of the chain 50, the multiple sprockets 51 also rotate synchronously, which is simple to operate and has a labor-saving structure. In other embodiments, the power element can directly adopt the servo motor 521 or other electric motor capable of adjusting forward and reverse rotation, and the output end of the motor can be directly fixedly connected to the end of the rotating rod 520, which is simple in structure and easy to implement.

[0045] Reference Figure 3 and Figure 6 In this embodiment, to securely connect the soil loading box 3 to the chain 50, a connecting rod 7 is rotatably connected to the side of the soil loading box 3 near the chain 50. The connecting rod 7 is fixedly connected to any link of the chain 50. Through the connection of the connecting rod 7, the connection between the soil loading box 3 and the chain 50 is more reliable and more convenient during processing. Support plates 70 are also arranged around both sides of the base plate 2. The connecting rod 7 is horizontally arranged on the top of the support plate 70. A support slider 71 is fixedly installed at the point where the connecting rod 7 passes through the support plate 70. The support slider 71 has a T-shaped cross-section and is provided with a sliding groove 72 on the support plate 70 for the sliding movement of the support slider 71.

[0046] When in use, the soil loading box 3 drives the connecting rod 7 to slide around the base plate 2. At this time, the connecting rod 7 is guided and supported by the support slider 71, so that during the use of the soil loading box 3, the connecting rod 7 transfers part of the load-bearing force to the support plate 70 through the support slider 71, thereby reducing the load on the chain 50 and reducing the possibility of chain 50 breaking, effectively improving the operating stability of the chain 50 and ensuring structural reliability.

[0047] Reference Figure 1 and Figure 3In this embodiment, the mounting assembly 4 includes a mounting plate 40 that overlaps the top of the foundation pit 1, a bracket 41 perpendicularly connected to the mounting plate 40, and a fixing member provided on the mounting plate 40 for fixing the mounting plate 40 to the top of the foundation pit 1. The bracket 41 is arranged in an inverted L shape, with two brackets 41 located on either side of the base plate 2. The horizontal sections of the brackets 41 are fixedly connected to the support plates 70 on both sides of the base plate 2, thereby effectively connecting the base plate 2 to the brackets 41 for use. The length direction of the connected mounting plate 40 is perpendicular to the length direction of the base plate 2, and the distance between the base plate 2 and the mounting plate 40 is not less than the height of the soil loading box 3. The mounting plate 40 is staggered with the blanking opening 20 on the base plate 2.

[0048] Therefore, by connecting the mounting plate 40 to the top of the foundation pit 1 through fixing parts, the base plate 2 can be effectively connected to the top of the mounting plate 40, so that the mounting plate 40 supports the base plate 2, and the mounting plate 40 will not interfere with the rotational movement of the soil loading box 3, so that the soil loading box 3 is firmly connected to the top of the foundation pit 1 for use, and the structure is reliable.

[0049] Reference Figure 1 and Figure 2 as well as Figure 3 In this embodiment, the fixing parts include fixing rods 42 provided on both sides of the mounting plate 40 in the width direction. Fixing holes 420 for the fixing rods 42 to pass through are provided on both sides of the mounting plate 40 in the width direction. According to the construction conditions of the foundation pit 1, there are multiple ways to install the mounting plate 40. The first way is to overlap any end of the mounting plate 40 on the soil foundation on one side of the top of the foundation pit 1, and extend the other end of the mounting plate 40 toward the building foundation 10 in the foundation pit 1. Then, the fixing rods 42 are inserted through the fixing holes 420 and inserted into the soil foundation. The mounting plate 40 is fixed to the top of the foundation pit 1 in a cantilevered manner, and the distance from the bottom plate 2 to the side wall of the foundation pit 1 is not less than the height of the soil loading box 3. At this time, the bottom plate 2 is effectively installed on the top of the foundation pit 1 for use.

[0050] The second method for securing mounting plate 40 involves overlapping both ends of mounting plate 40 on the top of foundation pit 1. This allows base plate 2 to extend toward building foundation 10 within foundation pit 1. The distance between one end of base plate 2 and the sidewall of foundation pit 1, and the distance between the other end of base plate 2 and building foundation 10, must be no less than the height of soil loading box 3. Fixing rods 42 are then inserted through fixing holes 420 into the soil at the top of foundation pit 1, effectively securing mounting plate 40 to the top of foundation pit 1 and completing the installation of base plate 2. There are multiple options for securing mounting plate 40; choosing the best solution based on the construction situation is highly practical.

[0051] However, when the first cantilever method is used to fix the mounting plate 40, when the base plate 2 is placed on the top of the foundation pit 1, it is completely supported by the mounting plate 40. In order to strengthen the installation of the mounting plate 40, anti-wear pads 8 are provided on both sides of the mounting plate 40 in the width direction. When the mounting plate 40 is cantilevered, the end of the mounting plate 40 extending toward the building foundation 10 is brought into contact with the building foundation 10. The anti-wear pads 8 effectively increase friction, making the mounting plate 40 more stable, and also reduce wear on the building foundation 10 by the mounting plate 40.

[0052] Reference Figure 3 In this embodiment, if the foundation pit 1 is large, the base plate 2 remains installed in one position, which is not conducive to leveling the backfill in the foundation pit 1. To allow the soil loading box 3 to evenly backfill the soil in different positions according to the size of the foundation pit 1, the flatness of the backfill in the foundation pit 1 is improved. A screw 9 is rotatably connected to the mounting plate 40 along its length. The screw 9 is threadedly connected to the bracket 41. The mounting plate 40 is also provided with a limiting groove 90 for the bracket 41 to slide. The length of the limiting groove 90 extends in the same direction as the length of the mounting plate 40. A clamping block is fixed to the end of the screw 9, and a removable rotating handle 91 is provided on the clamping block.

[0053] During use, the base plate 2 is prefabricated and connected to the mounting plate 40. At least two mounting plates 40 are installed. After the mounting plate 40 is fixed to the top of the foundation pit 1, the screw 9 is rotated using the handle 91. At this time, the bracket 41 slides along the limit groove 90 under the drive of the screw 9, thereby effectively adjusting the position of the base plate 2. The soil loading box 3 can be placed at different positions on the top of the foundation pit 1 and the soil is evenly filled into the foundation pit 1. After stopping the rotation of the screw 9, the bracket 41 automatically locks, the structure is stable, and the stable operation of the loading box on the base plate 2 is effectively ensured, which is very convenient to use.

[0054] The operating principle of the backfill soil transportation equipment of the embodiment of the present application is as follows: When backfilling the foundation pit 1, the mounting plate 40 is fixed to the top of the foundation pit 1 according to the use requirements, and then the screw 9 is rotated to adjust the position of the base plate 2. The servo motor 521 is started to drive the worm gear 522 and the worm 523 to rotate, thereby causing the rotating rod 520 to rotate synchronously, and the sprocket 51 drives the chain 50 to operate. At this time, the soil loading box 3 connected to the chain 50 effectively rotates and slides back and forth along the base plate 2 under the drive of the chain 50. After the soil is loaded in the soil loading box 3, as the soil loading box 3 slides, the discharge hole 30 and the discharge port 20 are aligned in sequence, effectively spreading the backfill soil in the foundation pit 1, saving time and labor in the construction operation and achieving a good paving effect.

[0055] The above are all preferred embodiments of the present application, and are not intended to limit the scope of protection of the present application. Therefore, any equivalent changes made based on the structure, shape, and principle of the present application should be included in the scope of protection of the present application.
