Description

Technical Field

[0001] This utility model relates to the field of lifting equipment technology, specifically a large component lifting equipment based on laser scanning. Background Technology

[0002] Components are used in building construction. They are steel or concrete components, such as steel beams, steel columns, or concrete blocks. Large components are large-volume components. Large-volume components require the use of large lifting equipment to move them during construction. Lifting equipment is an auxiliary tool used by lifting equipment. It connects to the components through clamping, hooking, adsorption, etc., to achieve stable lifting of heavy objects. In order to improve the efficiency of lifting equipment, laser scanners are usually used to scan the components, which can improve the efficiency and accuracy of lifting equipment.

[0003] Currently, there are still some shortcomings in the lifting equipment, such as the inconvenience of grabbing the equipment.

[0004] To overcome the inconvenience of container grabbing, a prior art Chinese patent (publication number: CN206395698U) discloses a machine vision-based RTG (Remote Container Grabber) that includes a grabber body with four target contour extractors and multiple grabbing devices. The target contour extractors are connected to frame receivers, which are wirelessly connected to a computer controller. Both the frame receivers and the computer controller have built-in wireless transmission modules. The grabbing devices have built-in wireless control modules and are connected to the computer controller via these modules. By introducing machine vision image processing technology and setting target contour extractors on the grabber body, the contour of the container to be grabbed is extracted from the background. The contour information is transmitted wirelessly to the computer controller via frame receivers. By calculating the corner points and straight lines of the container contour, the grabber is positioned to match the container, completing the automatic grabbing of the container. This improves work efficiency and reduces labor costs.

[0005] However, the lifting devices currently in use still have certain shortcomings. The lifting devices mentioned above improve the efficiency of grasping objects through machine vision, but the device is not convenient for precise fine-tuning of the lifting devices according to the angle or direction of the object, which will affect the lifting efficiency. In addition, the clamping parts of the lifting devices are not convenient to replace, which reduces the adaptability of the lifting devices. Therefore, it is necessary to improve the existing structure. Utility Model Content

[0006] The purpose of this invention is to provide a large component lifting tool based on laser scanning, so as to solve the problem mentioned in the background art that the lifting tool is inconvenient to adjust its own direction to follow the component structure, which affects the lifting efficiency.

[0007] To achieve the above objectives, this utility model provides the following technical solution: a large component lifting device based on laser scanning, including a lifting frame, a lifting ring connected to the top of the lifting frame, clamping hooks symmetrically connected to the bottom of the lifting frame, and laser scanners symmetrically installed at the bottom of the lifting frame.

[0008] The bottom of the lifting ring is fixed with an outer plate, and the bottom of the outer plate is provided with a rotating groove and an annular groove. The outer plate is equipped with a rotating mechanism to improve the lifting efficiency of the lifting device.

[0009] Furthermore, the rotating mechanism includes a motor mounted on the top of the outer plate, with a bevel gear connected to the output end of the motor, and the bevel gear rotating inside the rotating groove, with a bevel gear block meshing at the bottom of the bevel gear.

[0010] Furthermore, a small gear is fixed to the bottom end of the bevel gear block, and a large gear ring is meshed with the side of the small gear. Both the bevel gear block and the large gear ring rotate inside the rotating groove through bearings, and the large gear ring is fixed to the top of the hanger.

[0011] Furthermore, guide blocks are symmetrically fixed near the top of the large gear ring on the hanger, and the guide blocks slide through the annular groove.

[0012] Furthermore, the side of the hanger is provided with a sliding groove, and the sliding groove is provided with a disassembly and assembly mechanism for replacing the clamping hook. The disassembly and assembly mechanism includes a sliding frame that slides inside the sliding groove. The side of the hanger, the sliding frame and the clamping hook are all provided with through holes.

[0013] Furthermore, a positioning pin is slidably connected inside the through hole, and slots are symmetrically opened on the side of the clamping hook near the through hole. A limit block is also fixed inside the sliding groove.

[0014] Furthermore, the limiting block slides inside the sliding frame, and the side of the positioning pin is provided with a telescopic groove, which is connected to the telescopic block by a spring.

[0015] Compared with the prior art, the beneficial effects of this utility model are: 1. This laser scanning-based large component lifting device starts by starting a motor to drive a bevel gear to rotate, which in turn drives a bevel gear block to mesh and rotate. The rotation of the bevel gear block, through a small gear, drives a large gear ring to mesh and rotate. When the large gear ring rotates, it drives the lifting frame to rotate. When the lifting frame rotates, it drives a guide block to rotate and slide in an annular groove, so that it accurately falls onto the component lifting point, thereby improving the lifting efficiency of the lifting device.

[0016] 2. It is equipped with bevel gears and bevel gear blocks. The bevel gears and bevel gear blocks have different meshing ratios. The bevel gears can drive the bevel gear blocks to rotate with less effort, and the rotation speed of the bevel gear blocks is also slower, which can improve the stability of the hanger when adjusting the direction.

[0017] 3. It is equipped with a pinion and a large gear ring. The pinion and large gear ring are based on bevel gears and bevel gear blocks. By reducing the rotation speed of the hanger through the gear ratio, the stability of the hanger rotation can be further improved, thus improving the safety of component hoisting.

[0018] 4. Limit blocks are provided to guide and limit the sliding frame, preventing it from sliding out of the sliding groove and being lost, thus improving the safety of the lifting equipment components.

[0019] 5. It is equipped with a positioning pin, which can position the sliding frame, realizing the disassembly and assembly of the clamping hook. Furthermore, the positioning pin can be removed from the inside of the lifting frame by compression, improving the efficiency of the lifting device operation. Attached Figure Description

[0022] 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.

[0023] Example 1, such as Figures 1-4 The present invention provides the following technical solution: To solve the problem that the lifting device is inconvenient to adjust its own direction to follow the structural components, thus affecting the lifting efficiency, a rotating mechanism is disclosed, including a lifting frame 1. A lifting ring 2 is connected to the top of the lifting frame 1, and clamping hooks 3 are symmetrically connected to the bottom of the lifting frame 1. Laser scanners 4 are symmetrically installed at the bottom of the lifting frame 1. An outer receiving plate 101 is fixed to the bottom of the lifting ring 2. The bottom of the outer receiving plate 101 has a rotating groove 102 and an annular groove 103. A rotating mechanism to improve the lifting efficiency of the lifting device is provided inside the outer receiving plate 101. The rotating mechanism includes components installed on the outer receiving plate 101. The motor at the top of 01 has a bevel gear 104 connected to its output end. The bevel gear 104 rotates inside the rotating groove 102. A bevel gear block 105 is meshed with the bottom of the bevel gear 104. A small gear 106 is fixed to the bottom of the bevel gear block 105. A large gear ring 107 is meshed with the side of the small gear 106. Both the bevel gear block 105 and the large gear ring 107 rotate inside the rotating groove 102 through bearings. The large gear ring 107 is fixed to the top of the hanger 1. Guide blocks 108 are symmetrically fixed to the top of the hanger 1 near the large gear ring 107. The guide blocks 108 slide through the annular groove 103.

[0024] When in use, the laser scanner 4 can perform a full scan of large components, calculate the precise lifting point position of the large components based on the real-time scan data, and guide the operator to determine the lifting point position. After the position is determined, the motor can be started to drive the bevel gear 104 to rotate. When the bevel gear 104 rotates, it can drive the bevel gear block 105 to mesh and rotate. When the bevel gear block 105 meshes and rotates, it can rotate within the rotating groove 102 through the bearing. When the bevel gear block 105 rotates, it can drive the pinion 106 to rotate. When the pinion 106 rotates, it can drive the large gear ring 107 to mesh and rotate. When the large gear ring 107 meshes and rotates, it can also rotate through the bearing. When the large gear ring 107 rotates, it can drive the lifting frame 1 to rotate. When the lifting frame 1 rotates, it can drive the guide block 108 to rotate. When the guide block 108 rotates, it can rotate and slide within the annular groove 103. When the lifting frame 1 rotates, it can adjust the direction of the clamping hook 3, so that the clamping hook 3 can accurately fall to the lifting point position of the component, which can improve the lifting efficiency of the lifting equipment.

[0025] Example 2, as follows Figure 1 , Figures 5-7The present invention provides the following technical solution: In order to solve the problem that the clamping hook 3 of the lifting device is inconvenient to replace and difficult to adapt to different types of components, a disassembly and assembly mechanism is disclosed. The side of the lifting frame 1 is provided with a sliding groove 201. The sliding groove 201 is provided with a disassembly and assembly mechanism for replacing the clamping hook 3. The disassembly and assembly mechanism includes a sliding frame 202 that slides inside the sliding groove 201. The side of the lifting frame 1, the sliding frame 202 and the clamping hook 3 are all provided with through holes 203. A positioning pin 204 is slidably connected inside the through hole 203. The side of the clamping hook 3 near the through hole 203 is symmetrically provided with slots 205. A limit block 206 is also fixed inside the sliding groove 201. The limit block 206 slides inside the sliding frame 202. The side of the positioning pin 204 is provided with a telescopic groove 207, and the telescopic groove 207 is connected to a telescopic block 208 by a spring.

[0026] When using the lifting device, different components require different clamping hooks 3. Therefore, when replacing the clamping hooks 3, the telescopic block 208 can be pressed to slide through the telescopic groove 207. When the telescopic block 208 slides, it can compress the spring inside the telescopic groove 207. When the telescopic block 208 is compressed into the telescopic groove 207, the positioning pin 204 is pulled outward. When the positioning pin 204 is pulled, it can slide inside the through hole 203. When the positioning pin 204 slides out of the through hole 203, the sliding frame 202 is pulled to the side. When the sliding frame 202 is pulled, it can slide through the sliding groove 201, the slot 205 and the limiting block 206. When the sliding frame 202 slides out of the slot 205, the lifting frame 1 is raised. When the lifting frame 1 is raised, the clamping hooks 3 can slide out of the lifting frame 1 to separate. After the clamping hooks 3 are separated, they can be replaced with new models or types, which improves the adaptability of the lifting device to components.

[0027] Although the present invention 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 invention should be included within the protection scope of the present invention.
