Description

Technical Field

[0001] This invention relates to the field of retaining wall technology, specifically to a prefabricated retaining wall construction machine that is easy to assemble. Background Technology

[0002] A retaining wall is a structure that supports the fill or slope soil of a roadbed and prevents the fill or soil from deforming and becoming unstable. In engineering construction, it is a plate used to support and reinforce the pit wall. It can also be called a retaining wall. Currently, retaining walls are constructed by on-site pouring, that is, the concrete is mixed on-site, the steel bars are tied, and then the concrete is poured directly at the place where the retaining wall needs to be installed.

[0003] However, the existing construction devices for retaining walls have the following drawbacks:

[0004] 1. The existing retaining wall construction involves pouring concrete on-site to form the retaining wall. After construction, protective panels and other devices need to be removed. Furthermore, after pouring, it is necessary to wait for the concrete to set, which takes a lot of time and results in poor overall construction quality.

[0005] 2. The existing retaining walls are fixed to the foundation after construction. If problems arise in a certain place or if they need to be dismantled and replaced, it is difficult to remove them, so the existing retaining walls cannot be reused.

[0006] CN111962557A discloses an invention patent entitled "A Prefabricated Green Retaining Wall and Its Construction Method." In this invention, the retaining wall foundation is cast in place. During the reinforcement binding, vertical pre-reserved outward-extending reinforcement bars are reserved according to the design. When setting up the formwork, grooves for placing and positioning the prefabricated retaining wall modules are arranged according to the design. After pouring concrete to complete the retaining wall foundation construction, the prefabricated retaining wall modules are hoisted and installed into the positioning grooves of the retaining wall foundation. During hoisting and installation, the vertical pre-reserved outward-extending reinforcement bars extend into the cavity of the prefabricated retaining wall. Two rows of horizontal pre-reserved outward-extending reinforcement bars are tied or welded together with steel wire. The joints of the horizontal pre-reserved outward-extending reinforcement bars should be located in the post-poured secondary concrete, in a cross-shaped... Secondary concrete is poured into the cavity, and formwork is erected in the gaps on both sides of the retaining wall module. Then, the secondary concrete is poured to a depth from the top of the prefabricated retaining wall. After the secondary concrete has cured to the design strength, I-shaped partition plates are installed in the gaps between the flanges of the retaining wall modules to divide the upper layer of the cross-shaped cavity into two rectangular cavities. Then, the upper two rectangular cavities are filled with upper soil for planting green plants. The green plants are planted in the upper soil. Cement mortar is poured into the gaps in the grooves of the retaining wall foundation to complete the construction of the retaining wall and form a continuous retaining wall support. After the construction of the retaining wall is completed and a continuous retaining wall support is formed, green plants are planted in the soil of the upper cavity.

[0007] Its shortcomings are: 1. This invention requires a cast-in-place retaining wall foundation, which uses a large amount of steel bars and concrete. Although this makes it more solid, it requires a lot of time to wait for the concrete to solidify, resulting in poor performance; 2. This invention is only one layer high and can only install one layer of prefabricated retaining wall. It cannot firmly stack retaining walls, which makes this invention unsuitable for terrains with high retaining walls, and has strong limitations. Summary of the Invention

[0008] The purpose of this invention is to provide an easy-to-assemble prefabricated retaining wall and its construction device. It can complete the installation of the prefabricated retaining wall on the construction site without the need for concrete pouring. Moreover, it can be stably stacked one on top of the other, so that the height of the retaining wall is not limited. It is also convenient to disassemble and maintain, and has good performance.

[0028] The device also includes an excavator for digging soil to form the foundation for installing prefabricated retaining walls.

[0029] Because of the adoption of the above technical solution, the present invention has the following advantages:

[0030] 1. The seventh telescopic rod of this invention can work with the first multi-stage telescopic rod to push the guardrail into the first groove of the base. Moreover, this invention can turn the base, which is placed upside down, into the correct position before pushing it in. If the guardrail is assembled into the base at the beginning, the installation rod at the bottom of the base makes it difficult to transport the device smoothly. If it is transported upside down at the beginning, the guardrail will fall off. Solving these problems would require adding many structures. Therefore, the structure of transporting upside down first and then turning it into the correct position for assembly is cleverly designed, making the overall workflow more orderly.

[0031] 2. The prefabricated retaining wall designed in this invention has two staggered layers, making it less prone to collapse. It is also equipped with a protective railing to block soil and drain any groundwater that may be present in the soil. This makes the retaining wall structure of this invention ingenious and effective.

[0032] 3. When transporting the base, the present invention allows for the option of cutting or not cutting the mounting rods on the base. This is because mounting rods are not required when installing the base on the ground. If they were needed, many mounting holes would have to be drilled in the ground, which would increase the difficulty of construction. However, the present invention only requires the ground to be dug deep enough before placing the base. Therefore, the present invention simplifies the construction difficulty while ensuring stability and has good performance.

[0033] Other advantages, objectives, and features of the invention will be set forth in part in the description which follows, and in part will be apparent to those skilled in the art from the following examination, or may be learned from practice of the invention. The objectives and other advantages of the invention can be realized and obtained from the following description and claims. Attached Figure Description

[0047] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0048] In the description of the embodiments of the present invention, it should be noted that the terms "center," "longitudinal," "lateral," "upper," "lower," "front," "rear," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," and "outer," etc., indicating the orientation or positional relationship, are based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing the embodiments of the present 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 the embodiments of the present invention. Furthermore, the terms "first," "second," and "third" are used for descriptive purposes only and should not be construed as indicating or implying relative importance. In the description of the embodiments of the present invention, it should be noted that unless otherwise explicitly specified and limited, the terms "connected" and "linked" should be interpreted broadly. For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium. Those skilled in the art can understand the specific meaning of the above terms in the embodiments of the present invention based on the specific circumstances.

[0049] like Figure 1 As shown, the prefabricated retaining wall includes a base 1, a first mounting hole 2, a mounting rod 3, a first groove 4, a first through hole 5, a guardrail 6, and a second through hole 7;

[0050] The base 1 has two mounting rods 3 on its lower end face and two first mounting holes 2 on its upper end face. The inner diameter of the first mounting hole 2 is larger than the diameter of the mounting rod 3, and the axial extension line of the first mounting hole 2 coincides with the axial extension line of the mounting rod 3 at the corresponding position.

[0051] The upper surface of the base 1 is provided with a first groove 4, which is located between two first mounting holes 2. Two first through holes 5 are respectively provided on both sides of the base 1. The first through holes 5 connect the opposite end faces of the first groove 4 and are located between the two first mounting holes 2. The guardrail 6 is set in the first groove 4. The outer side wall of the guardrail 6 is fitted with the side wall around the first groove 4. Several second through holes 7 are evenly provided on the guardrail 6.

[0052] In this embodiment, during the assembly of the prefabricated retaining wall, the guardrails are installed into the first grooves of the base at designated positions. The bases are placed side-by-side with their first grooves facing upwards. Then, the two mounting rods below the upper row of bases are inserted into the two adjacent first mounting holes of the two adjacent bases, forming a staggered, overlapping retaining wall. The prefabricated retaining wall designed in this invention features two staggered layers, making it less prone to collapse. Furthermore, the guardrails prevent soil from draining away any groundwater that may be present in the soil. This makes the retaining wall structure of this invention ingeniously designed and highly effective.

[0053] like Figure 2 , Figure 3 As shown, the device includes a first feeding unit 8, a first conveying unit 9, a second feeding unit 10, a flipping assembly unit 11, and an installation unit 12;

[0054] The device further includes a first mounting box 13, in which the first feeding unit 8 and the first conveying unit 9 are both located. The first feeding unit 8 is located above the first conveying unit 9. The second feeding unit 10 is located in the first mounting box 13 and is located on one side of the first feeding unit 8. The flipping assembly unit 11 is located in the first mounting box 13 and is located on both sides of the second feeding unit 10. The mounting unit 12 can move into the first mounting box 13 and is located below the second feeding unit 10.

[0055] In this embodiment, at the start of operation, the first feeding unit conveys the bases one by one from bottom to top onto the first conveying unit. After the first conveying unit receives the bottom base, the installation unit enters the first installation box. The first conveying unit then transfers the received base to the installation unit. Next, the flipping assembly unit lifts and flips the base 180 degrees. The second feeding unit, in conjunction with the flipping assembly unit, pushes down the bottom guardrail, completing the assembly of the base and guardrail. The flipping assembly unit then places the assembled base and guardrail onto the installation unit, which performs the installation and assembly work. This invention allows for the initial inverted feeding of special bases (i.e., bases with mounting rods underneath), followed by flipping to receive the protective net. The protective net remains on top during assembly and will not fall out, making the workflow of this invention automatic and efficient.

[0056] like Figure 2 , Figure 3 As shown, the first feeding unit 8 includes a first telescopic rod 14 and a first pressing block 15;

[0057] The first mounting box 13 is horizontally open inside, and the first mounting box 13 has a vertically opened first channel 16. Two first telescopic rods 14 are horizontally fixed inside the first mounting box 13. The extended ends of the two first telescopic rods 14 are arranged opposite each other and both point from the side wall into the first channel 16. The extended ends of the first telescopic rods 14 are fixed with first pressure blocks 15, and the first pressure blocks 15 can extend into the first channel 16 from the side wall of the first channel 16.

[0058] In this embodiment, the first mounting box is first moved to a designated location. Inside the first mounting box, several bases are placed upside down in a first channel, with the bottom base pressed down on both sides by first pressure blocks. At the start of operation, the first pressure blocks are released by the retraction of the first telescopic rod. After the base falls a certain distance, the first telescopic rod extends again to press down on the side wall of the second-to-last base from bottom to top. The bottom base is then located at the first conveying unit, thus completing the base loading. This invention can automatically load bases, and because of the shape of the bases, upside-down loading saves materials. Furthermore, the overlapping loading method saves construction time, resulting in good performance.

[0059] like Figure 2 , Figure 3 , Figure 4 As shown, the first conveying unit 9 includes a second telescopic rod 17, a first mounting base 18, a first conveyor belt 19, a third telescopic rod 20, a first U-shaped block 21, a fourth telescopic rod 22, a first mounting block 23, a first motor 24, a first cutting disc 25, and a first collection box 26.

[0060] The second telescopic rod 17 is fixed inside the first mounting box 13, and the extended end of the second telescopic rod 17 is vertically upward. The extended end of the second telescopic rod 17 is fixed to the first mounting base 18. The upper end surface of the first mounting base 18 is horizontally provided with the first conveyor belt 19. The first collection box 26 is fixed to the side wall of the first mounting box 13. The first collection box 26 is located on one side of the output end of the conveyor belt.

[0061] The fourth telescopic rod 22 is horizontally fixed inside the first mounting box 13. The protruding end of the fourth telescopic rod 22 extends into the hollow interior of the first mounting box 13. The protruding end of the fourth telescopic rod 22 is fixedly connected to a first mounting block 23. A first motor 24 is fixedly connected inside the first mounting block 23. The rotating end of the first motor 24 extends out of the lower end face of the first mounting block 23. A first cutting disc 25 is fixedly connected to the rotating end of the first motor 24.

[0062] The third telescopic rod 20 is fixed inside the first mounting box 13. The third telescopic rod 20 is located at the end of the first channel 16 away from the first collection box 26. The extended end of the third telescopic rod 20 is vertically downward. The extended end of the third telescopic rod 20 is fixed with a first U-shaped block 21, which is an inverted U-shape.

[0063] In this embodiment, at the start of operation, the first pressing block is released first by the retraction of the first telescopic rod. After the base as a whole falls a certain distance, the first telescopic rod extends again to press down on the second-to-last base sidewall from bottom to top. The bottommost base then falls onto the first conveyor belt. Afterward, the second telescopic rod retracts, and the first conveyor belt begins to slide towards the first U-shaped block. When it is necessary to cut the installation rod (i.e., the retaining wall of the assembling base layer), the fourth telescopic rod extends as the first conveyor belt slides towards the first U-shaped block, causing the side of the first cutting disc away from the fourth telescopic rod to extend into the position of the installation rod to be cut. Then, the first motor continues to rotate, and as the base passes by, the top of it... The mounting rod is cut off, at which point the third telescopic rod extends, allowing the lower end of the first U-shaped block to fit against the upper end of the first conveyor belt. Then, as the base with the mounting rod cut off is transported out of the first conveyor belt, it smoothly exits along the U-shaped channel of the first U-shaped block. The first U-shaped block can block the cut-off mounting rod on the first conveyor belt. After the base is transported out, the first conveyor belt immediately reverses direction, finally transporting the cut-off mounting rod into the first collection box. When the mounting rod does not need to be cut (i.e., when assembling the retaining wall above the foundation), the fourth telescopic rod does not extend, nor does the third telescopic rod; the first conveyor belt directly transports the entire base to the installation unit. This invention allows for the selection of whether or not to cut the mounting rod on the base during transport. Since mounting rods are not needed when installing the base on the foundation, drilling numerous mounting holes in the foundation would increase construction difficulty. This invention only requires digging the foundation deep enough, thus simplifying construction while ensuring stability and achieving good results.

[0064] like Figure 2 , Figure 3 , Figure 5 , Figure 6 , Figure 11 As shown, the second feeding unit 10 includes a first multi-stage telescopic rod 27, a second mounting block 28, a fifth telescopic rod 29, a first mounting plate 30, a first fixing post 31, a first mounting strip 32, a sixth telescopic rod 33, a first baffle 34, and a first slider 35;

[0065] The first mounting box 13 has a vertically opened second channel 36. Two first multi-stage telescopic rods 27 are fixedly connected inside the first mounting box 13. The first multi-stage telescopic rods 27 are located on opposite sides of the second channel 36, and their extended ends are vertically downward. The extended ends of the first multi-stage telescopic rods 27 are fixedly connected to second mounting blocks 28. The fixed ends of fifth telescopic rods 29 are fixedly connected inside the second mounting blocks 28. The fifth telescopic rods 29 are horizontally fixed inside the second mounting blocks 28. The extended ends of the fifth telescopic rods 29 on both sides are arranged opposite to each other. The extended ends of the fifth telescopic rods 29 are fixedly connected to first mounting plates 30. The end face of the first mounting plate 30 away from the corresponding fifth telescopic rod 29 is fixedly connected to a first fixing post 31. The first fixing post 31 can extend into the second through hole 7 of the guardrail 6.

[0066] Two first mounting strips 32 are fixedly connected to the upper end of the hollow interior of the first mounting box 13. The first mounting strips 32 are located on opposite sides of the second channel 36. A sixth telescopic rod 33 is horizontally fixedly connected inside the first mounting strips 32. The extended ends of the sixth telescopic rods 33 on both sides are arranged opposite to each other. One end of a first baffle 34 is fixedly connected to the extended end of each sixth telescopic rod 33. The first baffles 34 on both sides can block the lower end face of the second channel 36. A first slider 35 is fixedly connected to both sides of the upper end face of the first baffle 34. A first sliding groove 37 is horizontally arranged inside the first mounting box 13 along the extension direction of the sixth telescopic rod 33. The first slider 35 can slide in the first sliding groove 37.

[0067] In this embodiment, when transporting guardrails, multiple guardrails are first placed in the second channel of the first mounting box, overlapping as required. At this time, a first baffle blocks the lower opening of the second channel. The first multi-stage telescopic rod retracts, aligning the first fixed post with the second through hole corresponding to the second-to-last guardrail from bottom to top. Then, the fifth telescopic rod extends, allowing the first fixed post to enter the second through hole. After the sixth telescopic rod retracts, exposing the second through hole through the first baffle, the first multi-stage telescopic rod extends downwards, thus transporting the bottommost guardrail. The guardrail and base are then assembled using a flipping assembly unit. This invention also uses an overlapping method when loading the protective netting, saving overall time and improving work efficiency.

[0068] like Figure 2 , Figure 7 As shown, the flipping assembly unit 11 includes a seventh telescopic rod 38, a third mounting block 39, a second motor 40, an eighth telescopic rod 41, a second mounting plate 42, a first double-headed telescopic rod 43, a second slider 44, a second slide groove 45, and a first gripper 46.

[0069] Two seventh telescopic rods 38 are fixedly connected inside the first mounting box 13. The seventh telescopic rods 38 are located on both sides of the second channel 36. The extended ends of the seventh telescopic rods 38 are vertically downward. A third mounting block 39 is fixedly connected to the extended end of each of the seventh telescopic rods 38. A second motor 40 is fixedly connected inside each of the third mounting blocks 39. The rotating ends of the second motors 40 on both sides are arranged opposite to each other and extend out of the opposite end faces of the corresponding third mounting blocks 39. The fixed end of an eighth telescopic rod 41 is rotatably fixed to the rotating end of the second motor 40. The eighth telescopic rod 41 is arranged horizontally, and the extension ends of the eighth telescopic rods 41 on both sides are... With the ends of the eighth telescopic rod 41 being arranged opposite each other, a second mounting plate 42 is fixedly connected to the extended end of each of the eight telescopic rods 41. A first double-headed telescopic rod 43 is horizontally fixedly connected inside the second mounting plate 42. A second slider 44 is fixedly connected to the extended ends of the first double-headed telescopic rod 43. A second sliding groove 45 is horizontally opened on the end face of the second mounting plate 42 away from the eighth telescopic rod 41. The second slider 44 can slide in the second sliding groove 45. A first clamp 46 is fixedly connected to the end face of the second slider 44 away from the eighth telescopic rod 41. The first clamp 46 extends out from the end face of the second mounting plate 42 away from the eighth telescopic rod 41.

[0070] In this embodiment, at the start of operation, the first pressure block is released first by the retraction of the first telescopic rod. After the base falls a certain distance, the first telescopic rod extends again to press down on the second-to-last base sidewall from bottom to top. The bottom base then falls onto the first conveyor belt. After that, the second telescopic rod retracts, and the first conveyor belt begins to slide towards the first U-shaped block. The first conveyor belt directly transports the base to the designated position of the installation unit. Then, the eighth telescopic rod extends, allowing the two first grippers to insert into the corresponding two first through holes. Then, the first double-headed telescopic rod retracts, allowing the first grippers to clamp the base. Then, with the retraction of the seventh telescopic rod, the entire structure moves upward. After moving upward a certain distance, the second motor rotates 180 degrees, causing the inverted base... The first groove is rotated back to its upward position, and then the seventh telescopic rod continues to retract, so that the upper end face of the base fits against the lower end face of the first baffle. Then, the first baffle moves away as the sixth telescopic rod retracts, and then the first multi-stage telescopic rod retracts, so that the first fixing post aligns with the second through hole corresponding to the second to last guardrail from bottom to top. Then, the fifth telescopic rod extends, so that the first fixing post extends into the second through hole. After the sixth telescopic rod retracts, so that the first baffle protrudes from the second through hole, the first multi-stage telescopic rod extends downward, thereby pressing the bottom guardrail downward into the first groove, completing the assembly of the base and the guardrail. After assembly, the seventh telescopic rod extends and places the base and the guardrail together on the installation unit, waiting for the installation operation. The seventh telescopic rod of this invention can work with the first multi-stage telescopic rod to push the guardrail into the first groove of the base. Moreover, this invention can turn the base, which is placed upside down, into the upright position before pushing it in. If the guardrail is assembled into the base at the beginning, the installation rod at the bottom of the base will make it difficult to transport the device smoothly, and many additional structures will be required to achieve this. Therefore, the structure of transporting the guardrail upside down and then assembling it into the upright position is cleverly designed, making the overall workflow more orderly.

One end of the first inclined surface 49 is connected to the bottom end face of one side of the first mounting groove 50, and the other end is connected to the upper side wall of the first vehicle body 47. A fourth multi-stage telescopic rod 52 is fixedly connected inside the first vehicle body 47. The extended end of the fourth multi-stage telescopic rod 52 extends vertically upward and can extend out of the upper end face of the first vehicle body 47. A first telescopic plate 53 is fixedly connected to the extended end of the fourth multi-stage telescopic rod 52. A fixed end of a robotic arm 54 is fixedly connected to the first telescopic plate 53. The robotic arm 54 has six degrees of freedom, and a first connecting post 55 is rotatably fixed to the output end of the robotic arm 54. One end of the first connecting post 55 is fixedly connected to a third motor 56. The rotating end of the third motor 56 extends out of the end face corresponding to one end of the first connecting post 55. The rotating end of the third motor 56 is rotatably fixedly connected to a fourth mounting block 57. When the upper end face of the fourth mounting block 57 is horizontally positioned above the first connecting post 55, a second multi-stage telescopic rod 58 is fixedly connected inside the fourth mounting block 57. The extended end of the second multi-stage telescopic rod 58 is fixedly connected to the side wall of a third slider 59. A first clamping plate 61 is fixedly connected to the end face of the third slider 59 away from the first connecting post 55. A first arc-shaped protrusion 62 is fixedly connected to the end face of the first clamping plate 61 near the end face of the second multi-stage telescopic rod 58. A third sliding groove 60 is horizontally opened on the end face of the fourth mounting block 57 away from the first connecting post 55. The sliding direction of the third sliding groove 60 is consistent with the extension and retraction direction of the second multi-stage telescopic rod 58. The third slider 59 can slide within the third sliding groove 60.

[0073] A third multi-stage telescopic rod 63 is fixedly connected inside the fourth mounting block 57. The extension direction of the third multi-stage telescopic rod 63 is opposite to that of the second multi-stage telescopic rod 58.

The fourth slider 64 can slide in the fourth sliding groove 65.

[0074] The device also includes an excavator 68 for digging soil to form the foundation for installing a prefabricated retaining wall.

[0075] In this embodiment, the excavator first digs out the foundation, places the excavated soil into the designated location, and then, after assembling the base and guardrail, places them in the first mounting slot of the first vehicle body. The first vehicle body then drives into the construction position and stops. First, the second and third multi-stage telescopic rods extend, causing the first and second clamping plates to open. The robotic arm rotates, causing the first and second clamping plates to cover the upper surface of the base. Then, the second and third multi-stage telescopic rods retract, causing the first and second arc-shaped protrusions to engage with the corresponding first through holes. The robotic arm, in conjunction with the extension of the fourth multi-stage telescopic rod, then removes the assembled base and guardrail as a whole. These components are then placed and assembled one by one. After placement, the excavator scoops out the accumulated soil to the size of the first groove and pours it into the first groove. This invention enables automatic construction and installation of the assembled base and guardrail, making the overall operation of the device smoother and highly automated.
