Description

Technical Field

[0001] This utility model relates to the field of building engineering technology, and in particular to a concrete 3D printing platform. Background Technology

[0002] The concrete 3D printing platform is a key component integrated into a concrete 3D printing system, serving additive manufacturing technology in the construction field. This platform works in collaboration with the 3D printer's robotic arm and extrusion system to print concrete materials into pre-defined building components or integral structures through a layer-by-layer deposition process. Its technological essence lies in combining the needs of architectural engineering with 3D printing technology to achieve digital construction and precise installation of concrete materials.

[0003] Traditional platforms only have a single printing surface. After the component is printed, the machine must be stopped and the surface disassembled before the next printing job can be carried out. At this time, the printing platform is in a stopped state, resulting in low work efficiency. To address this issue, a concrete 3D printing platform is proposed. Utility Model Content

[0004] To overcome the above shortcomings, this utility model provides a concrete 3D printing platform, which aims to improve the low efficiency of existing concrete 3D printing platforms that must stop and disassemble after printing a component.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a concrete 3D printing platform, including a left support, a horizontal plate fixedly connected to the upper right side of the left support, a right support fixedly connected to the right end of the horizontal plate, a concrete printing nozzle slidably connected to the outer wall of the horizontal plate, and a switching mechanism provided on the right side of the left support.

[0006] The switching mechanism includes a hydraulic rod fixedly connected to the right side of the left support. A movable plate is fixedly connected to the right movable end of the hydraulic rod. A movable plate is fixedly connected to the side of the movable plate away from the right support. A positioning component is provided on the right side of the movable plate. A disassembly plate is detachably installed on the left side of the movable plate by bolts.

[0007] As a further description of the above technical solution:

[0008] The outer wall of the movable plate is slidably connected to the inner wall of the right bracket.

[0009] As a further description of the above technical solution:

[0010] The disassembly plate and the movable plate have an inclined surface on the side that is close to each other.

[0011] As a further description of the above technical solution:

[0012] Both the disassembly plate and the movable plate are fixedly connected to casters at their bottoms.

[0013] As a further description of the above technical solution:

[0014] The top of the disassembly plate has a square groove, and a handle is fixedly connected inside the square groove.

[0015] As a further description of the above technical solution:

[0016] The positioning component includes a fixed plate fixedly connected to the right side of the movable plate. The inner wall of the fixed plate is elastically connected to a limit post via a connecting spring. A connecting hole is opened on the top right side of the disassembly plate. The bottom of the limit post is inserted into the inner wall of the connecting hole. The right side of the disassembly plate is in contact with the inner side wall of the fixed plate.

[0017] As a further description of the above technical solution:

[0018] The outer wall of the limiting post penetrates and is slidably connected to the inner wall of the fixing plate.

[0019] As a further description of the above technical solution:

[0020] The bottom of the limiting post has an inclined surface, which is set to the left.

[0021] This utility model has the following beneficial effects:

[0022] 1. In this utility model, through the cooperation between the left support, horizontal plate, right support, concrete printing nozzle and its switching mechanism, etc., when the concrete nozzle is printing above the disassembly plate, the operator can simultaneously disassemble the already formed components on the movable plate, avoiding the time loss of traditional single-work-face shutdown and waiting for post-processing, thereby improving the overall work efficiency.

[0032] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0033] Reference Figures 1-3 The present invention provides an embodiment of a concrete 3D printing platform, including a left support 1, a horizontal plate 2 fixedly connected to the upper right side of the left support 1, a right support 3 fixedly connected to the right end of the horizontal plate 2, a concrete printing nozzle 4 slidably connected to the outer wall of the horizontal plate 2, the concrete printing nozzle 4 and its multiple sets of supports and the horizontal plate 2 constitute a concrete 3D printing platform, and the concrete printing nozzle 4 can be moved. This is prior art and will not be explained in detail here. A switching mechanism 5 is provided on the right side of the left support 1.

[0034] Reference Figures 2-4The switching mechanism 5 includes a hydraulic rod 504 fixedly connected to the right side of the left support 1. A movable plate 505 is fixedly connected to the movable end of the right side of the hydraulic rod 504. The movable end of the hydraulic rod 504 can drive the movable plate 505 to move to the right. A movable plate 501 is fixedly connected to the side of the movable plate 505 away from the right support 3. Concrete printing can be performed above the movable plate 501. A positioning component 6 is provided on the right side of the movable plate 501. A disassembly plate 502 is detachably installed on the left side of the movable plate 501 by bolts 507. The connection of bolts 507 allows the movable plate 501 and its disassembly plate 502 to move synchronously. Concrete printing can be performed above the disassembly plate 502. The movable plate 501 or the disassembly plate 502 located at the bottom of the concrete printing nozzle 4 can perform printing work, while the other set can perform disassembly work.

[0035] Reference Figures 3-5 The outer wall of the movable plate 505 is slidably connected to the inner wall of the right bracket 3. The sliding arrangement supports the movement of the movable plate 505. An inclined surface is provided on the side of the disassembly plate 502 and the movable plate 501 that are close to each other. The inclined surface allows the disassembly plate 502 to be easily moved above the movable plate 501 when it is not in use, thus facilitating the overall transportation. The bottom of both the disassembly plate 502 and the movable plate 501 are fixedly connected to casters 503. The bottom of the casters 503 is in contact with the ground, and the casters 503 facilitate the horizontal movement of the movable plate 501 and the disassembly plate 502. A square groove is provided on the top of the disassembly plate 502, and a handle 506 is fixedly connected inside the square groove. The handle 506 facilitates the manual movement of the disassembly plate 502 to the left and then to the top of the movable plate 501.

[0036] Reference Figure 2 , Figure 3 and Figure 6 The positioning component 6 includes a fixed plate 601 fixedly connected to the right side of the movable plate 501. The fixed plate 601 is L-shaped. The inner wall of the fixed plate 601 is elastically connected to a limit post 603 via a connecting spring 604. The elasticity of the connecting spring 604 enables the limit post 603 to have the functions of resetting and limiting. A connecting hole 602 is opened on the top right side of the disassembly plate 502. The bottom of the limit post 603 is inserted into the inner wall of the connecting hole 602. The two are inserted to prevent the disassembly plate 502 from moving back and forth. The right side of plate 502 contacts the inner side wall of fixed plate 601. The contact setting prevents plate 502 from being disassembled and moved to the right. The outer wall of limiting post 603 penetrates and is slidably connected to the inner wall of fixed plate 601. The penetration setting facilitates manual upward movement of limiting post 603 to release the limitation. The bottom of limiting post 603 has a slope facing to the left. The slope setting facilitates the movement of movable plate 501 to the left. The right side of movable plate 501 presses against the slope, thereby causing limiting post 603 to move upward.

[0037] Working principle: When the concrete 3D printing platform is working, the concrete printing nozzle 4 slides along the horizontal plate 2 to perform printing operations. When it is necessary to switch the printing working surface or replace the disassembly plate 502, the switching mechanism 5 is operated: the hydraulic rod 504 is activated to drive the moving plate 505 to move to the right, and the moving plate 505 drives the movable plate 501 to move to the right simultaneously, so that the disassembly plate 502 is located below the concrete printing nozzle 4, while the movable plate 501 moves out of the area below the concrete printing nozzle 4. At this time, the concrete that has been printed above the movable plate 501 can be disassembled. After disassembly, the concrete above the disassembly plate 502 has been printed. Then, the hydraulic rod 504 is driven to reset, and the movable plate 501 can be moved out to remove the concrete above it, thereby improving work efficiency.

[0038] When it is necessary to replace the disassembly plate 502, first remove the bolt 507 inside the disassembly plate 502, and then move the disassembly plate 502 to the right using the handle 506. The universal wheel 503 at the bottom of the disassembly plate 502 enters the upper part of the movable plate 501 through the left inclined surface of the movable plate 501, and the right end of the disassembly plate 502 contacts and presses the inclined surface of the limiting post 603, thereby causing the limiting post 603 to move upward. When the right end of the disassembly plate 502 contacts the fixed plate 601, the elasticity of the connecting spring 604 causes the limiting post 603 to reset and be inserted into the connecting hole 602 to complete the fixation, so that the whole printing platform can be transported.

[0039] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
