Description

Technical Field

[0001] The invention relates to the technical field of construction engineering machinery, in particular to a fully automatic concrete spraying device. Background Art

[0002] Fully automatic concrete spraying equipment is an advanced construction equipment that integrates high efficiency, intelligence and environmental protection. It is designed for various complex engineering environments. Through the automated operating system, the equipment can realize full intelligent control of the concrete spraying process, greatly improving the construction efficiency and quality. With its precise spraying ability and excellent material utilization rate, fully automatic concrete spraying equipment plays an irreplaceable role in tunnels, mines, slope reinforcement and other projects. The design of the equipment fully considers the diversity and complexity of the construction site, and has the characteristics of strong stability, easy operation and low maintenance cost. The advent of fully automatic concrete spraying equipment marks that construction has entered a new era of intelligence. It is one of the important technological breakthroughs in the field of modern engineering construction. However, the equipment will still encounter some problems that need to be solved due to problems in the construction environment.

[0003] First, during the movement of concrete spraying equipment, especially on uneven construction sites, the equipment often encounters severe vibration and impact, which not only affects the operational stability of the equipment, but also accelerates the wear of the equipment and shortens its service life. Traditional construction equipment often lacks effective shock absorption measures, which makes the equipment prone to failure or damage when operating in complex terrain, thus affecting the construction progress and quality. Therefore, how to effectively reduce the transmission of vibration force and enhance the operational stability of the equipment has become an urgent problem to be solved;

[0004] Secondly, during the construction of concrete spraying equipment, evenly mixed concrete is the key to ensuring construction quality. However, in traditional mixing equipment, concrete is easily deposited at the bottom of the mixing tank, resulting in uneven mixing, affecting the fluidity and spraying effect of the concrete. The agglomeration problem not only wastes materials, but may also lead to construction quality problems, increase engineering costs and construction time. Traditional equipment usually requires manual intervention to remix the concrete that has settled to the bottom, which is time-consuming and laborious. In addition, existing concrete spraying equipment is usually driven by hydraulics, and it is difficult to accurately control the spraying range. Therefore, technologies that can automatically optimize the mixing process, improve concrete utilization, and accurately control the walking position become particularly important.

[0005] Finally, in the use of concrete shotcrete equipment, the use and recycling of pipes are common operating steps. Traditional pipe recycling usually relies on manual operation, which has certain safety hazards and operational complexity. When manually recycling pipes, it is easy for the pipes to be loosely wound, fall off or be damaged, which not only affects the construction efficiency, but may also cause equipment damage or safety accidents. In addition, the repeated use and recycling of pipes increases the labor intensity of operators and reduces the level of automation in construction. Therefore, how to improve the efficiency and safety of pipe recycling while reducing manual intervention is a major challenge in current technological development. Summary of the invention

[0012] A laser radar is movably installed in a movable slot on one side of the base through a driving mechanism and is used to scan the spraying operation area;

[0013] The shock absorbing mechanism comprises a connecting magnetic column, wherein the connecting magnetic column is arranged as two vertically symmetrical ones, and the ends of the connecting magnetic columns close to each other repel each other for the first buffering. A damper is arranged on one side of the connecting magnetic column for the second buffering.

[0014] Preferably, one side of the connecting magnetic pillars is rotatably connected to a docking rod, the end of the docking rod away from the connecting magnetic pillars is rotatably connected to a docking shaft, a sliding block is fixedly connected to the outer wall of the docking shaft, and a sealing block is slidably provided between the connecting magnetic pillars.

[0015] Preferably, sliding frames are fixed on both sides of the sealing block, the sliding block slides inside the sliding frame, a damper is installed inside the sliding frame, and the output end of the damper is fixed on one side of the sliding block.

[0016] Preferably, the stirring mechanism comprises a stirring tank, which is installed on one side of the base, a vertical frame is fixed on the top of the stirring tank, a motor is arranged inside the vertical frame, a driving shaft is installed at the output end of the motor, and a fixed frame is installed at the bottom end of the driving shaft.

[0017] Preferably, an auger blade is installed inside the fixed frame, which is used to transport the bottom concrete to the top for re-mixing. The outer wall of the fixed frame is fixedly connected to a mixing blade. A scraper rod is installed on the side of the mixing blade away from the fixed frame, which is used to scrape off the residual concrete on the inner wall of the mixing tank.

[0018] Preferably, an opening and closing plate is installed on the top of the mixing tank through a hinge.

[0019] Preferably, the telescopic mechanism comprises a rotating column, the rotating column is installed inside the cabinet, a connecting rod is slidably arranged inside the rotating column, and a limit plate is installed at one end of the connecting rod away from the rotating column.

[0020] Preferably, a spring is installed inside the connecting rod, one end of the spring is fixed inside the connecting rod, a connecting column is fixed to the other end of the spring, and a magnet 1 is installed inside the connecting rod.

[0021] Preferably, a second magnet is fixed to the outer wall of the connecting column, a ball bearing is arranged on one side of the connecting column, and the second magnet repels the first magnet.

[0022] Preferably, a solenoid valve is provided on one side of the base, and a plurality of output pipes are installed inside the base.

[0023] Working principle: Before the equipment is operated, the laser radar is used to scan the spraying operation area and plan the movement path of the equipment. When the equipment needs to be operated, in some uneven work sites, the vibration force generated by the movement of the equipment will first be transmitted to the position of the bottom connecting magnetic column through the base, so that the distance between the two connecting magnetic columns changes, and then the first buffering is performed through the principle of repulsion between the two connecting magnetic columns close to one side. Then, while the distance between the corresponding connecting magnetic columns changes, the corresponding inclination angle of the docking rod will also change, so that the docking rod drives the slider to apply force to the damper. Under the action of the damper, the vibration force generated is buffered for the second time. When the operation officially starts, the corresponding concrete will be poured into the mixing tank first. At this time, the motor is started synchronously, so that the motor drives the drive shaft to rotate, so that the drive shaft can drive the fixed frame to rotate synchronously. When the fixed frame rotates, the stirring blades arranged on its outer wall can drive the scraper rod to stir the concrete while scraping the concrete attached to the inner wall of the mixing tank. At the same time, the auger blades will also rotate synchronously with the fixed frame, so that the concrete that has sunk to the bottom but has not been transported out by the construction passes through The bottom gap of the fixed frame is transported up by the rotating auger blade, and then discharged from the gap position at the top of the auger blade to restart the mixing operation from the top to prevent caking. The concrete mixed in the mixing tank can be changed at any time by the solenoid valve to drive the valve to change, so that the concrete can be sprayed out through different output pipes for construction. When the construction site to be operated is small and only suitable for manual spraying, the solenoid valve can be used to change the pipeline transportation position and change it to a pipeline set at the position of the telescopic mechanism. When the manual construction pipeline is not needed, we can push the limit plate to The limit plate drives the connecting rod to retract into the rotating column. During the retraction of the connecting rod, the corresponding ball will first be acted upon by the force, and then push the connecting column to squeeze the spring, so that the connecting rod can smoothly slide into the rotating column. When the ball slides to the corresponding reserved slot, the corresponding spring generates a reaction force through its own restorability, and at the same time cooperates with the thrust generated by the repulsion of a pair of magnets, so that the connecting column drives the ball to sink into the slot to achieve engagement. It will not fall off without the action of a fixed axial external force. After retraction, the rotating column can be driven by the controller to rotate and wrap around the pipe for recovery.

[0024] The present invention provides a fully automatic concrete spraying equipment. It has the following beneficial effects:

[0025] 1. The present invention significantly reduces the transmission of vibration force when the equipment moves on uneven ground through double buffer design, ensuring that the equipment runs more smoothly in complex terrain. This effect directly extends the service life of the equipment, reduces the potential damage to the equipment caused by vibration, and improves the continuity of construction, avoiding interruptions and quality problems caused by vibration.

[0026] 2. The present invention can automatically lift the concrete that has sunk to the bottom to the top of the mixing tank through the stirring mechanism, making the stirring process more uniform and effectively avoiding the caking problem. This optimization ensures the efficient use of concrete and avoids material waste. At the same time, it ensures the quality and consistency of concrete during spraying construction and improves the overall construction effect of the project.

[0027] 3. The present invention can automatically recycle and lock unused pipes through the telescopic mechanism to prevent the pipes from falling off or being damaged during the recycling process. This effect makes the pipe recycling operation simpler and faster, while greatly improving safety, reducing the necessity of manual intervention, and ensuring the automation level of the equipment and the efficiency of construction preparation work.

[0028] 4. The present invention uses a laser radar to scan the spraying operation area, collect point cloud data, complete preliminary data collection of the spraying operation area, and then perform filtering and denoising preprocessing on the collected point cloud data to improve data quality, and transmit it to the controller. The point cloud data is divided into an area to be sprayed and a non-sprayed area by a processor inside the controller, and ground or background noise is eliminated. The point cloud data is used for three-dimensional reconstruction to generate a three-dimensional model of the area to be sprayed, and the boundary information of the spraying area is extracted from the three-dimensional model. According to the boundary information and the spraying requirements, the movement path of the equipment is planned to ensure the accuracy of the equipment's moving path, so as to achieve efficient and uniform spraying coverage.

DETAILED DESCRIPTION

[0039] The following will be combined with the drawings in the specification of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0040] Example:

[0041] Please see attached Figure 1 -Attached Figure 4 The embodiment of the present invention provides a fully automatic concrete spraying equipment, comprising:

[0042] A base 1 is provided with a cabinet 2 installed on the top thereof, and a controller 3 is provided on the top of the cabinet 2;

[0043] A mixing mechanism 4, which is installed on one side of the base 1 and is used for mixing concrete;

[0044] A telescopic mechanism 5, which is installed inside the cabinet 2 and is used to shrink the irrigation pipe;

[0045] A shock absorbing mechanism 6, which is installed between the base 1 and the cabinet 2, and is used to buffer damage caused by vibration to the cabinet 2 and the controller 3;

[0046] The shock absorbing mechanism 6 includes a connecting magnetic column 61, which is arranged to be two symmetrical upper and lower parts, and the ends of the connecting magnetic columns 61 that are close to each other repel each other for the first buffering. A damper 67 is arranged on one side of the connecting magnetic column 61, and the damper 67 is used for the second buffering. A docking rod 62 is rotatably connected to one side of the connecting magnetic column 61, and the docking rod 62 is rotatably connected to the end away from the connecting magnetic column 61. A slider 66 is fixedly connected to the outer wall of the docking shaft 65. A sealing block 63 slides between the connecting magnetic columns 61, and sliding frames 64 are fixed on both sides of the sealing block 63. The slider 66 slides inside the sliding frame 64, and a damper 67 is installed inside the sliding frame 64. The output end of the damper 67 is fixed to one side of the slider 66.

[0047] Specifically, when the equipment is working on an uneven work site, the vibration force generated during the movement of the equipment will first be transmitted to the position of the bottom connecting magnetic column 61 through the base 1. As the vibration force is transmitted, the distance between the two connecting magnetic columns 61 changes. This change is caused by the interaction force between the magnetic columns. Specifically, the magnetic forces close to one side of the two connecting magnetic columns 61 repel each other, causing them to quickly pull apart under the action of the vibration force, thus achieving the first buffer and reducing the intensity of the vibration directly transmitted to other parts of the equipment; at the same time, as the distance between the connecting magnetic columns 61 changes, the corresponding docking rod 6 2 will also change the tilt angle, which further triggers the movement of the docking rod 62, driving the slider 66 to move in a specific direction. The movement of the slider 66 will exert a certain force on the damper 67, so that the damper 67 starts to play a role. The damper 67 absorbs and attenuates the applied force through the internal damping medium or structure, thus achieving a second buffering of the vibration force. Through such a double buffering mechanism, the vibration generated when the equipment moves on an uneven site is effectively absorbed and weakened, thereby improving the stability and safety of the equipment operation, reducing the damage to the internal structure of the equipment, and ensuring the normal operation of the equipment.

[0048] Please see attached Figure 5 The stirring mechanism 4 includes a stirring tank 41, which is installed on one side of the base 1. A vertical frame 42 is fixed on the top of the stirring tank 41. A motor 43 is arranged inside the vertical frame 42. A driving shaft 44 is installed at the output end of the motor 43. A fixed frame 45 is installed at the bottom of the driving shaft 44. An auger blade 46 is installed inside the fixed frame 45, which is used to transport the bottom concrete to the top for re-stirring. A stirring blade 47 is fixedly connected to the outer wall of the fixed frame 45. A scraper rod 48 is installed on the side of the stirring blade 47 away from the fixed frame 45, which is used to scrape the residual concrete on the inner wall of the stirring tank 41. An opening and closing plate 49 is installed on the top of the stirring tank 41 through a hinge.

[0049] Specifically, the concrete will first be poured into the mixing tank 41 to start the whole mixing process. At this time, by synchronously starting the motor 43, the motor 43 starts to run and drives the drive shaft 44 to rotate. As the drive shaft 44 rotates, the fixed frame 45 is also synchronously driven to rotate. During the rotation of the fixed frame 45, the stirring blades 47 arranged on the outer wall thereof play a key role. These stirring blades 47 can not only fully stir the concrete, but also drive the scraper rod 48 to work together. The scraper rod 48 scrapes the concrete attached to the inner wall of the mixing tank 41 with the movement of the stirring blades 47, effectively preventing the concrete from adhering to the inner wall of the mixing tank 41, ensuring that the concrete is evenly mixed and avoiding material waste; At the same time, the auger blades 46 also rotate synchronously when the fixed frame 45 rotates. The role of the auger blades 46 is particularly important. It can transport the concrete deposited at the bottom of the mixing tank 41 to the upper part again. Specifically, through the notch at the bottom of the fixed frame 45, the auger blades 46 gradually transport the concrete that has sunk to the bottom, and then discharge it from the notch at the top of the auger blades 46. In this way, the concrete that has sunk to the bottom is sent back to the upper part of the mixing tank 41 and enters the mixing cycle again, effectively preventing the concrete from caking in the tank. The whole process ensures the uniformity and continuity of the concrete, avoids construction quality problems caused by the sinking of concrete, and at the same time improves the utilization rate of the concrete, ensuring the efficient progress of the mixing operation.

[0050] Please see attached Figure 6 -Attached Figure 7 The telescopic mechanism 5 includes a rotating column 51, which is installed inside the cabinet 2. A connecting rod 52 is slidably arranged inside the rotating column 51. A limit plate 53 is installed at one end of the connecting rod 52 away from the rotating column 51. A spring 54 is installed inside the connecting rod 52. One end of the spring 54 is fixed inside the connecting rod 52. A connecting column 55 is fixed at the other end of the spring 54. A magnet 1 56 is installed inside the connecting rod 52. A magnet 2 57 is fixed on the outer wall of the connecting column 55. A ball 58 is arranged on one side of the connecting column 55. The magnet 2 57 and the magnet 1 56 repel each other.

[0051] Specifically, when the manual construction pipeline is not needed, the limit plate 53 can be pushed manually, so that the limit plate 53 drives the connecting rod 52 to retract into the rotating column 51. In this process, as the connecting rod 52 retracts, the corresponding ball 58 will first be affected by the thrust from the limit plate 53. Under the push of the force, the ball 58 begins to push the connecting column 55, and then applies an extrusion force to the spring 54. This extrusion process allows the connecting rod 52 to slide smoothly into the rotating column 51 without being stuck due to the resistance of the spring 54; when the ball 58 slides to the preset slot, the spring 54 generates a reaction force through its own elastic restoring force, pushing the connecting column 55 back to its original position. At the same time, the repulsion between the magnet 1 56 and the magnet 2 57 also generates a thrust, which further enhances the driving force of the ball 58, so that the ball 58 can accurately sink into the slot. Thereby, a secure engagement between the connecting rod 52 and the rotating column 51 is achieved. Since this engagement combines the restoring force of the spring 54 and the repulsive force of the magnet, the connecting rod 52 will not fall off accidentally even without applying a fixed axial external force, thereby ensuring the safety and reliability of the equipment; once the connecting rod 52 is successfully retracted and engaged, the rotating column 51 can be driven to rotate by the controller 3, and then the pipeline can be neatly wound around the rotating column 51 for recovery. This process not only greatly improves the automation level of the equipment, but also reduces the complexity and workload of manual operation. During the entire retraction and recovery process, the equipment can maintain stable operation, ensuring that the pipeline can be quickly and orderly recovered in place, providing convenience for subsequent construction or storage. This design not only improves the operating efficiency of the equipment, but also extends the service life of the equipment and pipeline, and avoids damage that may be caused by manual misoperation.

[0052] Please see attached Figure 8 A solenoid valve 7 is arranged on one side of the base 1, and a plurality of output pipes 8 are installed inside the base 1.

[0053] Specifically, the concrete being mixed in the mixing tank 41 can change its flow direction at any time through the control of the solenoid valve 7. The solenoid valve 7 flexibly controls the flow direction of the concrete by driving the valve to open and close, so that it can be sprayed out through different output pipes 8 to meet the needs of various construction operations. When the concrete flows out of the mixing tank 41, it first passes through the solenoid valve 7. At this time, the setting of the solenoid valve 7 determines which output pipe 8 the concrete will be guided to, thereby achieving precise construction operations; in the case where the construction site is small and only suitable for manual spraying operations, the equipment can change the delivery path of the concrete by adjusting the solenoid valve 7. Specifically, by adjusting the setting of the solenoid valve 7, the flow direction of the concrete can be changed to be transported through a pipeline connected to the telescopic mechanism 5. This design greatly improves the flexibility of the equipment, enabling it to adapt to various construction environments. Even in a space-constrained site, concrete can still be accurately transported to the location where spraying is required in this way, ensuring the continuity and efficiency of the construction.

[0054] Please see attached Figure 8 -Attached Fig. 9 , a laser radar 9 is movably installed in a movable groove on one side of the base 1 through a driving mechanism, and is used to scan the spraying operation area.

[0055] Specifically, before the equipment is carrying out construction work, the driving mechanism can be set to drive the spiral screw to rotate by the driving motor, and then drive the laser radar 9 to move back and forth. The spraying operation area is scanned by the movement of the laser radar 9, and the point cloud data is collected to complete the preliminary data collection of the spraying operation area. The collected point cloud data is then pre-processed by filtering and denoising to improve the data quality, and transmitted to the controller 3. The point cloud data is divided into the area to be sprayed and the non-sprayed area by the processor inside the controller 3, and the ground or background noise is eliminated. The point cloud data is used for three-dimensional reconstruction to generate a three-dimensional model of the area to be sprayed, and the boundary information of the spraying area is extracted from the three-dimensional model. According to the boundary information and the spraying requirements, the movement path of the equipment is planned to ensure the accuracy of the equipment movement path, so as to achieve efficient and uniform spraying coverage.

[0056] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
