Description

Technical Field

[0001] This utility model relates to the field of construction surveying and positioning technology, and in particular to a positioning device for pre-embedded parts of rotary kiln foundation based on three-dimensional laser scanning. Background Technology

[0002] The embedded parts of the rotary kiln foundation require high precision during equipment installation. Traditional positioning methods often rely on manual measurement, which is prone to errors and affects the stability and service life of the equipment. With the development of three-dimensional laser scanning technology, its high precision and speed can effectively improve the accuracy and efficiency of embedded part positioning, providing more reliable technical support for the installation of rotary kilns.

[0003] However, in actual use, the following shortcomings still exist. For example, the existing rotary kiln foundation embedded part positioning device based on three-dimensional laser scanning is not convenient for multi-dimensional adjustment and coordination to ensure that the scanner accurately captures the data of the rotary kiln foundation embedded parts. The scanning range is limited, making it difficult to cover the complex spatial distribution of the embedded parts, and data blind spots are prone to occur, resulting in the loss of some embedded part position information. The angle adjustment is insufficient, making it unable to adapt to the installation state of the embedded parts such as tilting or concealment. The scanned data is prone to deviation or distortion, affecting the positioning accuracy. The height and horizontal position adjustment is inflexible, making it difficult to match the height difference of different kiln foundations and the distribution span of embedded parts, resulting in a poor scanning angle and increased data splicing error. Ultimately, this will cause inaccurate positioning of the embedded parts, which in turn will affect the docking accuracy during the installation of the rotary kiln. Utility Model Content

[0004] The purpose of this invention is to overcome the shortcomings of existing technologies and propose a positioning device for pre-embedded parts of rotary kiln foundations based on three-dimensional laser scanning. To achieve the above objective, this invention adopts the following technical solution:

[0005] A positioning device for embedded parts in a rotary kiln foundation based on three-dimensional laser scanning, comprising at least a guide rail, and further comprising:

[0006] An angle adjustment assembly includes a support frame mounted on a guide rail, a servo motor mounted at the bottom of the support frame, a support frame connected to the output end of the servo motor, an electric push rod mounted on the support frame, a connecting plate connected to the output end of the electric push rod, a rack connected to the connecting plate, a gear meshing on the rack, a mounting base connected to the gear, and a 3D laser scanner mounted on the mounting base.

[0007] A lifting assembly, comprising a cylinder mounted on a guide rail, a clamping plate at the output end of the cylinder, and a support frame mounted on the clamping plate.

[0008] Furthermore, the support frame is rotatably connected within the support frame.

[0009] The beneficial effects of adopting the above-mentioned further solution are: the support frame provides an installation base for the support frame, and the rotatable connection between the two allows the support frame to rotate around the connection point. When driven by the servo motor, the support frame can rotate stably inside the support frame, driving the subsequently connected electric push rod, 3D laser scanner and other components to rotate synchronously, providing structural support and movement space for the horizontal angle adjustment of the scanner.

[0010] Furthermore, a limiting seat is connected to the side of the support frame near the rack, and the rack is slidably connected to the limiting seat.

[0011] The beneficial effects of adopting the above-mentioned further solution are: the limiting seat is fixed on the support frame, and its internal structure is adapted to the rack, which restricts the sliding trajectory of the rack. When the electric push rod pushes the connecting plate to move the rack, the limiting seat can prevent the rack from deviating, ensuring that the rack is always precisely meshed with the gear, and ensuring the stability and accuracy of the angle adjustment.

[0012] Furthermore, a support block is connected to the support frame, and the gear is rotatably connected to the support block.

[0013] The beneficial effects of adopting the above-mentioned further solution are: the support block serves as the mounting carrier for the gear, and is fixed on the support frame to provide stable support for the gear. The gear is rotatably connected to the support block, allowing the gear to rotate flexibly around its own axis. When the rack moves to mesh with the gear, the gear can rotate smoothly on the support block, thereby driving the mounting base and scanner to adjust their angles.

[0014] Furthermore, a guide rod is connected to the cylinder, and a moving block is provided at the output end of the cylinder, the moving block being slidably connected to the guide rod.

[0015] The beneficial effects of adopting the above-mentioned further solution are: the guide rod is fixed to the cylinder, providing sliding guidance for the moving block. When the cylinder is ventilated and extends, its output end drives the moving block to slide along the guide rod. The guide rod can limit the movement direction of the moving block and prevent the moving block from deviating during the lifting and lowering process.

[0016] Furthermore, the clamp is connected to the moving block.

[0017] The beneficial effects of adopting the above-mentioned further solution are: one end of the clamping plate is fixed to the moving block, and the other end is used to install the support frame. When the moving block moves along the guide rod under the drive of the cylinder, it will drive the clamping plate to move synchronously, thereby enabling the support frame on the clamping plate and the subsequent angle adjustment components and scanner to move together on the guide rail, so as to realize the adjustment of the scanner height to adapt to different scanning scenario requirements.

[0018] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0019] When the device of this utility model is working, the cylinder extends and retracts to drive the clamping plate to fix the angle adjustment component, so that the 3D laser scanner can move on the guide rail and adjust the height of the 3D laser scanner to adapt to the scanning requirements. In the angle adjustment component, the servo motor drives the support frame to rotate, realizing the horizontal angle adjustment of the scanner. The electric push rod extends and retracts to drive the connecting plate and rack to move. The rack meshes with the gear to rotate, so that the scanner on the mounting base can complete the vertical angle adjustment. The multi-dimensional adjustment and coordination ensure that the scanner accurately captures the data of the pre-embedded parts of the rotary kiln foundation. Attached Figure Description

[0028] 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.

[0029] Example 1:

[0030] like Figures 1-6 As shown, this embodiment provides a technical solution for a rotary kiln foundation embedded part positioning device based on three-dimensional laser scanning, which includes at least a guide rail 1, and also includes:

[0031] Angle adjustment component 2 includes a support frame 21 mounted on the guide rail 1. A servo motor 22 is mounted at the bottom of the support frame 21. The output end of the servo motor 22 is connected to a support frame 23. An electric push rod 24 is mounted on the support frame 23. The output end of the electric push rod 24 is connected to a connecting plate 25. A rack 26 is connected to the connecting plate 25. A gear 29 meshes on the rack 26. A mounting base 210 is connected to the gear 29. A three-dimensional laser scanner 211 is mounted on the mounting base 210.

[0032] The lifting assembly 3 includes a cylinder 31 mounted on the guide rail 1. The output end of the cylinder 31 is equipped with a clamping plate 34, and a support frame 21 is mounted on the clamping plate 34. When the device is working, the cylinder 31 extends and retracts, driving the clamping plate 34 to fix the angle adjustment assembly 2, so that the 3D laser scanner 211 can move on the guide rail 1 and adjust the height of the 3D laser scanner 211 to adapt to the scanning requirements. In the angle adjustment assembly 2, the servo motor 22 drives the support frame 23 to rotate, realizing the horizontal angle adjustment of the scanner. The electric push rod 24 extends and retracts, driving the connecting plate 25 and the rack 26 to move. The rack 26 meshes with the gear 29 to rotate, so that the scanner on the mounting base 210 completes the vertical angle adjustment. The multi-dimensional adjustment and coordination ensures that the scanner accurately captures the data of the embedded parts of the rotary kiln foundation.

[0033] Example 2:

[0034] like Figure 1 as well as Figures 3-6As shown, the support frame 23 is rotatably connected within the support frame 21, which provides the mounting base for the support frame 23. This rotatable connection allows the support frame 23 to rotate around the connection point. When driven by the servo motor 22, the support frame 23 can rotate stably within the support frame 21, causing subsequent connected components such as the electric push rod 24 and the 3D laser scanner 211 to rotate synchronously. This provides structural support and movement space for adjusting the scanner's horizontal angle. A limiting seat 27 is connected to the side of the support frame 23 near the rack 26. The rack 26 is slidably connected to the limiting seat 27, which is fixed to the support frame 23. The limiting seat 27's internal structure is adapted to the rack 26, restricting the sliding trajectory of the rack 26. When the electric push rod 24 pushes the connecting plate 25 to move the rack 26, the limit seat 27 can prevent the rack 26 from deviating, ensuring that the rack 26 is always precisely meshed with the gear 29, and ensuring the stability and accuracy of the angle adjustment. The support frame 23 is connected to the support block 28, and the gear 29 is rotatably connected to the support block 28. The support block 28 serves as the mounting carrier for the gear 29 and is fixed on the support frame 23 to provide stable support for the gear 29. The gear 29 is rotatably connected to the support block 28, allowing the gear 29 to rotate flexibly around its own axis. When the rack 26 moves to mesh with the gear 29, the gear 29 can rotate smoothly on the support block 28, thereby driving the mounting base 210 and the scanner to adjust the angle.

[0035] like Figures 1-2 As shown, a guide rod 32 is connected to the cylinder 31. A moving block 33 is provided at the output end of the cylinder 31. The moving block 33 is slidably connected to the guide rod 32. The guide rod 32 is fixed to the cylinder 31 and provides sliding guidance for the moving block 33. When the cylinder 31 is ventilated and extends, its output end drives the moving block 33 to slide along the guide rod 32. The guide rod 32 can limit the movement direction of the moving block 33 and prevent the moving block 33 from deviating during the lifting and lowering process. A clamping plate 34 is connected to the moving block 33. One end of the clamping plate 34 is fixed to the moving block 33, and the other end is used to install the support frame 21. When the moving block 33 moves along the guide rod 32 under the drive of the cylinder 31, it will drive the clamping plate 34 to move synchronously, so that the support frame 21 on the clamping plate 34 and the subsequent angle adjustment component 2 and scanner can move together on the guide rail 1 to realize the adjustment of the scanner height to adapt to different scanning scenario requirements.

[0036] Working principle:

[0037] like Figures 1-6As shown, in the lifting assembly 3, after the cylinder 31 is ventilated, its output end drives the moving block 33 to slide along the guide rod 32. The guide rod 32 restricts the movement direction of the moving block 33 to prevent deviation. The moving block 33 drives the clamping plate 34 to move synchronously, so that the clamping plate 34 clamps the fixed support frame 21, thereby raising and lowering the support frame 21 on the clamping plate 34, the angle adjustment assembly 2, and the scanner together, thereby accurately adjusting the height of the scanner to adapt to different scanning scenario requirements. The support frame 21 of the angle adjustment assembly 2 provides an installation base for the support frame 23. The two are rotatably connected so that the support frame 23 can rotate around the connection point. When the servo motor 22 is started, its output end drives the support frame 23 to rotate stably in the support frame 21, driving the electric push rod 24, the 3D laser scanner 211 and other components to rotate synchronously, realizing the horizontal angle adjustment of the scanner.

[0038] Regarding vertical angle adjustment, when the electric push rod 24 extends or retracts, it drives the connecting plate 25 and the rack 26 to move. The rack 26 is slidably connected to the limiting seat 27 fixed to the support frame 23. The limiting seat 27 restricts the sliding trajectory of the rack 26, ensuring that it is always precisely meshed with the gear 29. The gear 29 is rotatably connected to the support block 28 of the support frame 23. Under the meshing action of the rack 26, it rotates smoothly around its own axis, thereby driving the mounting base 210 and the scanner to rotate, completing the vertical angle adjustment. Through the height adaptation of the lifting component 3 and the multi-dimensional angle adjustment of the angle adjustment component 2, the device can flexibly adjust the scanner posture to ensure that it accurately captures various data of the rotary kiln foundation embedded parts.

However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the technical solution of the present utility model.
