Description

Technical Field

[0001] This application relates to the field of soft foundation treatment, specifically a long-arm rotary lifting plate breaker capable of breaking through the hard crust of soft soil. Background Technology

[0002] Soft soil is widely distributed in my country. Soft soil possesses engineering characteristics such as high water content, high compressibility, poor permeability, low strength, and a long time required for deformation stabilization. Therefore, soft soil requires reinforcement treatment before it can be used as a foundation for subsequent construction work. The appropriateness of soft soil foundation treatment directly affects the performance of buildings and the quality of the project. Plastic drainage boards are often used for drainage reinforcement in soft soil treatment. Plastic drainage boards, also known as plastic drainage strips, come in various shapes such as wavy and harmonica-shaped. The core is an extruded plastic core board, serving as an excellent vertical channel for saturated cohesive soils (such as silt, silty soil, and fill) in soft soil foundation treatment using drainage consolidation methods, significantly shortening the consolidation time.

[0003] Currently, existing methods for inserting drainage boards mainly include manual insertion and machine insertion. Manual insertion requires workers to insert the drainage boards into soft soil, which is not only dangerous for workers but also inefficient. Machine insertion utilizes a vibratory hammer to press the plastic drainage board to the bottom of the foundation. While more efficient than manual insertion, machine insertion sometimes suffers from insufficient bearing capacity in soft soil, requiring frequent repositioning of the board, and sometimes the board is placed in a single location. Furthermore, some soft soils have a hard crust, making both manual and machine insertion difficult.

[0004] Therefore, a device is needed that can perform insert plate operations quickly, efficiently, and safely to meet the needs of insert plate operations for soft soil foundation reinforcement. Summary of the Invention

[0005] The purpose of this application is to provide a long-arm rotary lifting slab insertion machine capable of breaking through the hard shell layer of soft soil. It can break through the hard shell layer before insertion, insert multiple slabs at a single point, and simultaneously insert slabs remotely into soft soil with insufficient bearing capacity via its long arm. It enables fast, efficient, and safe slab insertion operations on soft soil foundations. The technical solution of this invention is as follows:

[0006] A long-arm rotary lifting plate-breaking machine capable of breaking through soft soil hard crust layers includes a mechanical arm 1 and a lifting device 17 connected to the mechanical arm 1. The mechanical arm 1 is characterized by having multiple hydraulic drainage plate support pipes 14 and annular drainage plate rolls 13 fixed on one side, with the starting end of the annular drainage plate roll 13 fixedly connected to the top inlet of the hydraulic drainage plate support pipes; a ground-turning structure is fixed on the other side. The mechanical arm 1 is connected to the lifting device 17 via annular support plate 19 and a turntable. The annular support plate 19 can move up and down relative to the lifting device 17, and the turntable 18 is rotatably connected to the outer circumference of the annular support plate 19, allowing the mechanical arm 1 to rotate via the turntable 18.

[0007] Furthermore, the outer periphery of the lifting device 17 is provided with a groove, and the inner wall of the groove is equipped with a vertically arranged electric guide rail 16. The outer wall of the electric guide rail 16 is slidably connected to an electric slider, and the outer wall of the electric slider is fixedly connected to the annular support plate 19.

[0008] Furthermore, a portion below the robotic arm 1 is a truss structure 9; the ground-turning structure on one side of the robotic arm and the annular drainage plate roll 13 on the other side are both connected to the truss structure 9.

[0009] Furthermore, the tillage structure includes tillage blades 10 and tillage plowshares 11.

[0010] Furthermore, each hydraulic drainage plate support pipe 14 includes a support pipe outer wall 4 and a pile drill 2, piston pipe 3, hydraulic cylinder 5 and hydraulic control valve 6 disposed inside the top inlet; wherein the hydraulic control valve 6 is connected to the hydraulic source 8 through high-pressure oil and low-pressure oil pipelines, and the hydraulic control valve 6 and the hydraulic source 8 are connected to the operation control console 7.

[0011] Furthermore, the outer wall of the supporting pipe 4 is a through structure. When the hydraulic drainage plate support pipe 14 is inserted, the hydraulic source 8 injects high-pressure oil into the upper chamber of the hydraulic cylinder 5, pushing the piston pipe 3 to rise and driving the pile drill 2 to rise to the preset height. Subsequently, the hydraulic control valve 6 switches the oil circuit to connect the upper and lower chambers of the hydraulic cylinder, forming a downward thrust to push the pile drill 2 to insert. The pile drill 2 extends out or passes through the outer wall of the supporting pipe and inserts into the soil, while simultaneously driving the drainage plate of the annular drainage plate roll 13) into the soil layer. After the plate is inserted, the hydraulic source (8) supplies oil in the reverse direction, and high-pressure oil is injected into the lower chamber of the hydraulic cylinder (5). The piston pipe (3) drives the pile drill (2) to retract.

[0012] Furthermore, the distance between each hydraulic drainage plate support pipe 14 on the robotic arm 1 is different, and is adjusted according to the rotation angle and rotation plate radius at the location of each hydraulic drainage plate support pipe (14) to achieve a uniform plate insertion effect.

[0013] The beneficial effects of this application are as follows: This embodiment provides a long-arm rotary lifting inserter capable of breaking through soft soil hard crust layers, comprising a mechanical arm and a lifting device connected to the mechanical arm. Multiple hydraulic drainage plate support pipes and annular drainage plate rolls are fixed on one side of the mechanical arm, while a soil-turning structure, namely soil-turning blades and a soil-turning plowshare, is fixed on the other side. The mechanical arm is connected to the lifting device via an annular support plate, allowing the mechanical arm to move up and down. A turntable is rotatably connected to the outer circumference of the annular support plate, allowing the mechanical arm to rotate via the turntable. The long-arm rotary lifting inserter provided by this application can quickly and efficiently break through hard soil layers for inserting inserts. Simultaneously, the inserter can remotely insert inserts into soft soil with insufficient bearing capacity via its long arm, making it safer and more reliable. Attached Figure Description

[0029] The following describes in further detail the features and performance of the long-arm rotary lifting plate-breaking machine capable of breaking through soft soil hard crust layers of this application, with reference to embodiments.

[0030] This application provides a long-arm rotary lifting plate-breaking machine capable of breaking through soft soil hard crust layers. (Refer to...) Figure 1 and Figure 2 The system includes a robotic arm 1 and a lifting device 17 connected to the robotic arm 1. Multiple hydraulic drainage plate support pipes 14 and annular drainage plate rolls 13 are fixed to one side of the robotic arm 1, while a tilling structure, namely tilling blades 10 and tilling plowshares 11, is fixed to the other side. The robotic arm 1 is connected to the lifting device 17 via annular support plates 19. A turntable 18 is rotatably connected to the outer circumference of the annular support plate 19, allowing the robotic arm 1 to rotate. The lifting device 17 has grooves on its outer perimeter, and each of the four grooves has a vertically arranged electric guide rail 16 mounted on its inner wall. Electric sliders are slidably connected to the outer walls of the four electric guide rails 16, and the outer walls of the four electric sliders are bolted to the annular support plate 19, thus allowing the robotic arm 1 to move up and down.

[0031] Reference Figure 3 and Figure 4One side of the robotic arm 1 is fixed with each hydraulic drainage board support pipe 14 and an annular drainage board roll 13 fixed to the truss 9 below the robotic arm. The starting end of the drainage board roll is fixed to the top entrance of the hydraulic drainage board support pipe by a buckle or clamp, that is, close to the top of the outer wall 4 of the support pipe outside the pile drill. The hydraulic source 8 required for the hydraulic drainage board support pipe is fixed above the robotic arm 1. Each hydraulic drainage board support pipe 14 consists of a pile drill 2, a piston pipe 3, a hydraulic cylinder 5, a hydraulic control valve 6, and the outer wall 4 of the support pipe. The hydraulic control valve 6 is connected to the hydraulic source 8 through high-pressure oil and low-pressure oil pipelines. The hydraulic control valve 6 and the hydraulic source 8 are connected to the operation control valve 7. When the lifting device 17 falls, the robotic arm 1 drives the hydraulic drainage board support pipe 14 to fall. When the hydraulic drainage board support pipe 14 is inserted into the soil, the hydraulic source 8 injects high-pressure oil into the upper chamber of the hydraulic cylinder 5, pushing the piston pipe 3 to rise, and driving the pile drill 2 to rise to the preset height. Subsequently, hydraulic control valve 6 switches the oil circuit, connecting the upper and lower chambers of the hydraulic cylinder (differential connection), generating a downward thrust to push the pile drill 2 downward at high speed. The lower end of the outer wall 4 of the support pipe opens, and the pile drill 2 penetrates the outer wall and inserts into the soil, simultaneously driving the drainage plate of the annular drainage plate roll 13 into the soil layer. After the plate is inserted, hydraulic source 8 supplies oil in the reverse direction, and high-pressure oil is injected into the lower chamber of hydraulic cylinder 5, causing piston tube 3 to drive the pile drill 2 to retract. After the pile drill 2 is fully retracted, the outer wall 4 of the support pipe closes under hydraulic action to prevent soil backfilling and blockage. Lifting device 17 raises robotic arm 1, preparing for the next plate insertion or rotation to a new position.

[0032] Reference Figure 5 and Figure 6 The lower part of the robotic arm 1 is a truss structure 9. The tilling blade 10 and tilling plow 11 on one side of the robotic arm are both connected to the truss structure 9, and the power supply 12 required by the tilling blade 10 and tilling plow 11 is fixed at the non-truss structure part of the robotic arm 1.

[0033] When using the long-arm rotary lifting plate-inserting machine for breaking up soft soil hard shell layers provided in this embodiment, the operator first positions the plate-inserting machine according to the plate-setting position marks. If the bearing capacity of the soft soil foundation is insufficient, the plate-inserting machine can be positioned outside the machine according to the length of the robotic arm 1 and the plate-inserting point. The plate-inserting machine is driven into the designated location, and the hydraulic drainage plate support pipe 14 is arranged and fixed according to the plate-setting position requirements, with reasonable spacing. The annular drainage plate roll 13 is fixed to the truss structure 9 according to the arrangement points of the hydraulic drainage plate support pipe 14. If there is a hard shell layer, it is inconvenient to insert the plate directly. After the robotic arm 1 is lowered, the power supply 12 of the tilling blade 10 and tilling plow 11 is turned on to start rotating and breaking up the hard soil layer. When the hard soil layer is sufficiently broken up, the robotic arm 1 is raised and then lowered. When the hydraulic drainage plate support pipe 14 is inserted into the soil, the support pipe 14 drives the annular drainage plate roll 13 to penetrate deeper into the soil through hydraulic action. After reaching the insertion depth, the operator cuts the drainage plate. When the hydraulic drainage board support pipe 14 is lifted off the soil under hydraulic pressure, the worker fixes the annular drainage board roll 13 to the support pipe 14. The robotic arm 1 is raised and rotated around the lifting device 17 via the turntable 18. After rotating to a fixed angle, the robotic arm 1 falls to insert the board. The above steps are repeated until the board insertion at that location is completed, and then the board insertion machine is driven to the next location.

The detailed description of the embodiments of this application is not intended to limit the scope of the claimed application, but merely to illustrate selected embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of this application without inventive effort are within the scope of protection of this application.
