[0002] During the construction of foundation pit earthwork, the quality of slope trimming directly affects the stability of the foundation pit, the safety of subsequent construction, and the overall quality of the project. To ensure that the slope surface is flat and the compaction meets the standards, special tools are required to trim and process the slope to remove loose soil, fill depressions, and achieve surface compaction, thereby avoiding safety hazards such as collapse and landslides caused by irregular slopes.

[0003] Existing tools are mostly fixed in length and cannot be flexibly adjusted according to the actual length of the foundation pit slope. When facing foundation pit slopes of different depths or lengths, multiple sizes of tools are required, which not only increases construction costs but also makes it inconvenient to carry and store the tools, thus reducing construction efficiency. To solve the above problems, this application proposes a foundation pit earthwork slope trimming tool. Utility Model Content

[0004] The purpose of this utility model is to address the shortcomings of existing technologies by proposing a tool for repairing the slope of foundation pits. By increasing or decreasing the number of second connecting rods, the overall size of the tool can be freely adjusted according to the actual length of the foundation pit slope. This eliminates the need to equip the tool with multiple specifications, reduces construction costs, and improves the tool's adaptability to slopes of different depths and lengths, thereby increasing construction efficiency.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: A tool for trimming the slope of an excavation pit includes a slope trimming roller, a U-shaped frame rotatably connected to the slope trimming roller, a T-shaped block detachably connected to the U-shaped frame, a replacement mechanism between the U-shaped frame and the T-shaped block, a first connecting rod fixedly connected to the bottom of the T-shaped block, a second connecting rod connected to the first connecting rod, and a third connecting rod connected to the second connecting rod, both the first and second connecting rods having grooves, and a fixing post fixedly connected to both the second and third connecting rods, the outer wall of the fixing post being threadedly connected to the inner wall of the groove, and a fixing ring fixedly connected to the bottom of the third connecting rod.

[0006] Preferably, both ends of the slope trimming roller are coaxially fixedly connected to rotating rods, and the ends of the two rotating rods are rotatably connected to the inner wall of the U-shaped frame.

[0007] Preferably, the replacement mechanism includes a T-slot formed on a U-shaped frame, the T-block is inserted into the T-slot and slidably connected thereto, and a plurality of locking bolts are installed on the U-shaped frame, all of which extend into the T-block.

[0008] Preferably, the U-shaped frame has a through hole, the T-shaped block has a threaded groove, the locking bolt is arranged through the through hole, and the locking bolt is threaded to the inner wall of the threaded groove.

[0009] Preferably, the outer wall of the fixing column is provided with an external thread, and the inner wall of the groove is provided with an internal thread that mates with the external thread.

[0010] Preferably, the outer wall of the third connecting rod is fitted with a protective sleeve, and the protective sleeve is made of rubber.

[0011] Compared with the prior art, the advantages of this utility model are as follows: 1. By increasing or decreasing the number of second connecting rods, the overall size of the tool can be freely adjusted according to the actual length of the foundation pit slope. There is no need to equip multiple specifications of tools, which reduces construction costs while improving the tool's adaptability to slopes of different depths and lengths, thereby increasing construction efficiency.

[0012] 2. By utilizing the sliding fit of the T-slot between the U-shaped frame and the T-block, and the fixing structure of the locking bolts, the working parts and operating parts can be quickly disassembled and assembled. When the working parts are worn or damaged, they can be replaced without the need for overall disassembly tools, reducing maintenance time and ensuring construction progress.

[0013] 3. The slope trimming roller is flexibly connected to the U-shaped frame through a rotating rod, which can closely fit the natural curvature of the slope and complex terrain, ensuring more thorough compaction and leveling of local areas, effectively improving the flatness and compaction of the slope surface, and enhancing the structural stability of the foundation pit slope.

[0014] In summary, by increasing or decreasing the number of second connecting rods, the overall size of the tool can be freely adjusted according to the actual length of the foundation pit slope. This eliminates the need to equip the tool with multiple specifications, reduces construction costs, enhances the tool's adaptability to slopes of different depths and lengths, and improves construction efficiency.

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0018] Reference Figures 1-2 A tool for trimming the slope of an excavation pit includes a slope trimming roller 1. The slope trimming roller 1 is used to directly contact the slope of the excavation pit and achieves compaction and leveling of the slope surface through rotation. The slope trimming roller 1 is rotatably connected to a U-shaped frame 2, which provides installation support for the slope trimming roller 1 and enables flexible rotation of the slope trimming roller 1 through cooperation with rotating rods 3. Both ends of the slope trimming roller 1 are coaxially fixedly connected to rotating rods 3, which connect the slope trimming roller 1 to the U-shaped frame 2 to ensure that the slope trimming roller 1 can rotate stably around its own axis. The ends of the two rotating rods 3 are rotatably connected to the inner wall of the U-shaped frame 2.

[0019] The U-shaped frame 2 is detachably connected to a T-shaped block 4. The T-shaped block 4 connects the U-shaped frame 2 to the first connecting rod 8 below, enabling the connection between the trimming component and the operating component. A replacement mechanism is provided between the U-shaped frame 2 and the T-shaped block 4. The replacement mechanism includes a T-shaped groove 5 formed on the U-shaped frame 2. The sliding engagement between the T-shaped groove 5 and the T-shaped block 4 provides guidance for the assembly and disassembly of the U-shaped frame 2 and the T-shaped block 4, ensuring precise alignment. The T-shaped block 4 is inserted into the T-shaped groove 5 and slidably connected thereto. Multiple locking mechanisms are installed on the U-shaped frame 2. Bolt 6, the locking bolt 6, passes through the through hole and is threadedly connected to the threaded groove 7 to fasten the U-shaped frame 2 and the T-shaped block 4, preventing them from sliding relative to each other. Multiple locking bolts 6 extend into the T-shaped block 4. The U-shaped frame 2 has a through hole, and the T-shaped block 4 has a threaded groove 7. The threaded groove 7 provides a threaded connection point for the locking bolt 6, ensuring the fixing effect of the locking bolt 6 on the U-shaped frame 2 and the T-shaped block 4. The locking bolt 6 is arranged through the through hole and is threadedly connected to the inner wall of the threaded groove 7.

[0020] The bottom of the T-block 4 is fixedly connected to a first connecting rod 8. The first connecting rod 8 bears the force of the T-block 4 and transmits the force to the operating end through its connection with the second connecting rod 9. The first connecting rod 8 is connected to the second connecting rod 9, which is the core component for length adjustment. The overall length of the device can be changed by increasing or decreasing the number of rods to adapt to different slope trimming needs. The second connecting rod 9 is connected to a third connecting rod 10, which is located at the end of the device and connects the second connecting rod 9 to the fixing ring 14. It also provides an installation base for the protective sleeve 13. Both the first connecting rod 8 and the second connecting rod 9 have grooves 12. The grooves 12 are threaded to the fixing post 11, enabling detachable fixing between adjacent connecting rods for quick assembly and length adjustment. Fixed posts 11 are fixedly connected to both the first connecting rod 8 and the second connecting rod 9, and the second connecting rod 9 and the third connecting rod 10. The fixed posts 11 are threadedly connected to the groove 12 to ensure a stable connection between the first connecting rod 8 and the second connecting rod 9, and between the second connecting rod 9 and the third connecting rod 10. The outer wall of the fixed posts 11 and the inner wall of the groove 12 are threadedly connected. The outer wall of the fixed posts 11 is provided with external threads, and the inner wall of the groove 12 is provided with internal threads that mate with the external threads. A fixed ring 14 is fixedly connected to the bottom of the third connecting rod 10. The fixed ring 14 can be used to connect external traction components or auxiliary tools to improve the flexibility of device operation. A protective sleeve 13 is fitted on the outer wall of the third connecting rod 10. The protective sleeve 13 provides a grip for the operator. The rubber material enhances grip comfort and anti-slip effect. The protective sleeve 13 is made of rubber.

[0021] In this invention, the number of second connecting rods 9 can be adjusted according to the length of the foundation pit slope. The first connecting rod 8 and the second connecting rod 9, as well as the second connecting rod 9 and the third connecting rod 10, are connected by screw rotation. The length of the device can be adjusted by arranging an appropriate number of second connecting rods 9 to meet different usage needs. The operator can operate the device by holding the protective sleeve 13 and pressing the slope trimming roller 1 against the slope of the foundation pit. This allows for surface compaction and leveling of local areas, completing the trimming and processing of the foundation pit slope.
