Description

Technical Field

[0001] The present application relates to the field of soft foundation treatment, and is a long-arm rotary lifting plate inserter capable of breaking soft soil hard crust layers. Background Art

[0002] Soft soil is widely distributed in my country, and soft soil has engineering characteristics such as high water content, high compressibility, poor permeability, low strength and long time required for deformation stabilization. Soft soil needs to be reinforced before it can be used as a foundation and subsequent construction work can be carried out. Therefore, the appropriateness of soft soil foundation treatment is directly related to the performance of the building and the quality of the project. When reinforcing soft soil, plastic drain boards are often used for drainage reinforcement. Plastic drain boards are also known as plastic drainage belts, which come in a variety of shapes such as wave-shaped and harmonica-shaped. In the middle is an extruded plastic core board, which is a good vertical channel for saturated clay such as silt, silt soil, and backfill soil, that is, miscellaneous fill soil, using drainage consolidation method for soft foundation treatment, which can greatly shorten the consolidation time of soft soil.

[0003] The existing methods of inserting drainage boards mainly include: manual insertion method and board insertion machine method. Among them, manual insertion requires workers to insert drainage boards on soft soil foundations, which is not only dangerous for workers, but also has low efficiency; the board insertion machine method mainly uses the board insertion machine to sink the plastic drainage board to the bottom of the foundation through a vibrating hammer to align the insertion hole. Compared with the manual board insertion method, the board insertion machine method is more efficient, but sometimes the soft soil does not have enough bearing capacity for the board insertion machine to insert the board, and one board is in one position, and the position needs to be moved continuously to insert the board. Some soft soils have a hard shell layer, which is not easy to insert manually or by the board insertion machine.

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

[0005] The purpose of this application is to provide a long-arm rotary lifting plate inserter that can break the hard crust layer of soft soil, which can destroy the hard crust layer before inserting the plate, rotate and insert multiple plates at one point, and insert the plate on the soft soil with insufficient bearing capacity remotely through the long arm.

[0011] Furthermore, the supporting outer tube wall 4 is a centrally-through structure. When the hydraulic drainage board supporting tube 14 is inserted downward, the hydraulic source 8 injects high-pressure oil into the upper chamber of the hydraulic cylinder 5, pushing the piston tube 3 upward, driving the pile drill 2 to rise to a preset height; then, 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 downward; the pile drill 2 extends out or passes through the outer wall of the supporting tube and inserts into the soil, while driving the drainage board of the annular drainage board roll 13) into the soil layer; after the board is inserted, the hydraulic source (8) supplies oil in the reverse direction, the lower chamber of the hydraulic cylinder (5) is injected with high-pressure oil, and the piston tube (3) drives the pile drill (2) to retract.

[0029] The features and performance of the long-arm rotary lifting plate inserter capable of breaking the soft soil hard crust layer of the present application are further described in detail below in conjunction with the embodiments.

[0030] The present application provides a long-arm rotary lifting plate inserter that can break the soft soil hard crust layer. Figure 1 and Figure 2 , which includes a mechanical arm 1 and a lifting device 17 connected to the mechanical arm 1. A plurality of hydraulic drain board support pipes 14 and annular drain board rolls 13 are fixed on one side of the mechanical arm 1, and a soil turning structure, namely a soil turning blade 10 and a soil turning plowshare 11, is fixed on the other side. The mechanical arm 1 is connected to the lifting device 17 through an annular support plate 19. The circumferential outer wall of the annular support plate 19 is rotatably connected to a turntable 18, and the mechanical arm 1 can rotate through the turntable 18. The lifting device 17 is provided with grooves on the outside around it, and the inner walls of the four grooves are equipped with vertically arranged electric guide rails 16, the outer walls of the four electric guide rails 16 are slidably connected to electric sliders, and the outer walls of the four electric sliders are connected to the annular support plate 19 by bolts, so the mechanical arm 1 can be lifted up and down.

[0031] Reference Figure 3 and Figure 4On one side of the mechanical arm 1, each hydraulic drain board support pipe 14 and an annular drain board roll 13 fixed to the truss 9 below the mechanical arm are fixed. The starting end of the drain board roll is fixed to the top entrance of the hydraulic drain board support pipe by a buckle or a clamp, that is, it 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 drain board support pipe is fixed on the top of the mechanical arm 1. Each hydraulic drain board support pipe 14 is composed of a pile drill 2, a piston tube 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 is connected to the hydraulic source 8 and the operating control valve 7. When the lifting device 17 falls, the mechanical arm 1 drives the hydraulic drain board support pipe 14 to fall. When the hydraulic drain board support pipe 14 is inserted into the soil, the hydraulic source 8 injects high-pressure oil into the upper cavity of the hydraulic cylinder 5, pushes the piston tube 3 up, and drives the pile drill 2 to rise to a preset height. Subsequently, the hydraulic control valve 6 switches the oil circuit, connecting the upper and lower chambers of the hydraulic cylinder (differential connection), forming a downward thrust, pushing the pile drill 2 to be inserted at high speed. The lower end of the outer wall 4 of the support tube opens, and the pile drill 2 passes through the outer wall and inserts into the soil, while driving the drainage board of the annular drainage board roll 13 into the soil layer. After the board is inserted, the hydraulic source 8 supplies oil in the reverse direction, and the lower chamber of the hydraulic cylinder 5 is injected with high-pressure oil, and the piston tube 3 drives the pile drill 2 to retract. After the pile drill 2 is fully retracted, the outer wall 4 of the support tube closes under the action of the hydraulic pressure to prevent blockage by soil backfill. The lifting device 17 lifts the mechanical arm 1 to prepare for the next board insertion or rotation to a new point.

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

[0033] When the long-arm rotary lifting plugging machine provided in this embodiment that can break the hard crust layer of soft soil is used, the staff will first position the plugging machine according to the board placement mark. If the bearing capacity of the soft soil foundation is insufficient, the plugging machine can be positioned outside the plugging machine according to the length of the mechanical arm 1 and the plugging point. Drive the plugging machine to the designated location, arrange and fix the hydraulic drain board support pipe 14 according to the requirements of the board placement, arrange the spacing reasonably, and fix the annular drain board roll 13 on the truss structure 9 according to the arrangement point of the hydraulic drain board support pipe 14. If there is a hard crust layer, it is inconvenient to directly plug the board. After lowering the mechanical arm 1, start the power supply 12 of the tilling blade 10 and the tilling plowshare 11, and start rotating to destroy the hard soil layer. When the hard soil layer is destroyed enough, lift the mechanical arm 1 and then drop it. When the hydraulic drain board support pipe 14 is inserted into the land, the support pipe 14 drives the annular drain board roll 13 to be deeply inserted into the soil through the hydraulic action. After reaching the plugging depth, the staff cuts off the drain board. When the hydraulic drain board support pipe 14 is lifted up and away from the soil under the action of hydraulic pressure, the staff fixes the annular drain board roll 13 on the support pipe 14. The mechanical arm 1 is lifted and rotated around the lifting device 17 through the turntable 18. After rotating to a fixed angle, the mechanical arm 1 falls to insert the board, and the above steps are repeated until the board insertion of the board insertion machine point is completed, and the board insertion machine is driven to the next board insertion machine point.

[0034] The embodiments described above are part of the embodiments of the present application, rather than all of the embodiments. The detailed description of the embodiments of the present application is not intended to limit the scope of the present application for protection, but merely represents the selected embodiments of the present application. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present application.
