Description

Technical Field

[0001] This utility model relates to the field of mechanical engineering technology, and in particular to an undulating mechanism for maintaining the posture of installed equipment. Background Technology

[0002] With the development of industrial automation and precision manufacturing, attitude stability during equipment installation has become a key factor affecting efficiency and safety. For example, in scenarios such as autonomous landing of drones and operation of wave energy power generation devices, attitude maintenance mechanisms can effectively reduce the impact of external interference on equipment, improving operational accuracy and reliability. Furthermore, attitude control mechanisms also play a crucial role in engineering hoisting and the installation of large equipment, significantly reducing the complexity and risks of manual operation.

[0003] In the installation and maintenance of power equipment, hoisting or lifting equipment is commonly used to precisely move heavy components to a designated height, reducing the complexity and risk of manual operation. However, existing technologies have significant limitations: traditional hoisting equipment is prone to swaying during the undulation process due to flexible connections, severely affecting positioning accuracy and installation efficiency; while lifting equipment can provide stable vertical lifting, its structure is usually fixed and lacks effective angle adjustment capabilities. When multi-angle alignment installation or maintenance of the internal components of power equipment is required, operation remains extremely inconvenient, failing to meet the dual requirements of stability and flexibility in modern power installation. Utility Model Content

[0004] One objective of this invention is to provide an undulating mechanism for maintaining the posture of the installation equipment. This invention addresses the problem mentioned in the background that traditional hoisting equipment is prone to swaying during undulation due to flexible connections, which seriously affects positioning accuracy and installation efficiency. While lifting equipment can provide stable vertical lifting, its structure is usually fixed and lacks effective angle adjustment function. When multi-angle alignment installation or maintenance of the internal electrical equipment is required, the operation is still extremely inconvenient.

[0005] An undulating mechanism for maintaining the posture of an installed device according to an embodiment of the present invention includes: An undulating mechanism includes a frame and a support platform directly above it. The frame has legs fixedly installed at its bottom, the support platform has ball seats fixedly installed at its bottom, and a mounting base is fixedly installed at the top of the frame. An extension arm is fixedly installed on the outside of the support platform. The support platform is connected to the frame through a first drive assembly to achieve adjustment of undulation and angle. A positioning mechanism is installed inside the support platform for positioning electrical equipment on the top of the support platform. A moving mechanism is installed at the bottom of the legs. The positioning mechanism includes an inner ring and an outer ring fixedly installed on the inner and outer sides of the support platform, respectively. An inner toothed ring is rotatably installed at the lower inner end of the outer ring. A rack is movably installed at the top slot of the outer ring through a limiting plate. A movable plate is fixedly installed at one top end of the rack. A clamping plate is fixedly installed at the top of the movable plate. The clamping plate is connected to the support platform through a second drive assembly to achieve relative retraction and extension.

[0006] Preferably, the support leg, ball seat, and mounting base are arranged in three sets in a circular shape.

[0007] Preferably, the extension arms are circular and there are four of them.

[0008] Preferably, both the frame and the support platform have weight-reducing grooves inside.

[0009] Preferably, the first drive assembly includes a first servo motor fixedly installed inside the mounting base and a ball movably disposed inside the ball seat. The output end of the first servo motor is fixedly provided with a large arm, and a small arm is rotatably provided on one side of the large arm. The small arm and the ball are fixedly disposed together.

[0010] Preferably, the inner ring has through holes corresponding to the rack and the limiting plate, and one side of the clamping plate is provided with an anti-slip pad.

[0011] Preferably, the second drive assembly includes a second servo motor fixed to the bottom of the support platform, and a gear rotatably disposed between the outer ring and the inner ring. The gear corresponds to the rack and is configured for meshing transmission. The gear and the inner gear ring are configured for meshing transmission. One of the gears is fixedly disposed at the output end of the second servo motor.

[0012] Preferably, the moving mechanism includes a hydraulic push cylinder fixedly installed inside the outrigger, and the output end of the hydraulic push cylinder is fixedly provided with a foot, and the bottom of the foot is rotatably provided with a moving wheel.

[0013] The beneficial effects of this utility model are: 1. This utility model effectively avoids the problems of swaying caused by flexible connections in traditional hoisting equipment and the inconvenience of operation due to the lack of angle adjustment function in lifting equipment by setting up an undulating mechanism. When adjusting the undulating height, the first drive component is activated, and three sets of first servo motors fixed inside the mounting base drive the boom to perform pitching motion. At the same time, the forearm connected to it and the ball fixed at its end rotate in multiple angles within the ball seat, thereby achieving stable undulation of the support platform. When angle adjustment is required, only one or two sets of servo motors are needed to adjust the angle in all directions. Therefore, this rigid connection mechanical arm structure replaces the flexible sling, fundamentally eliminating swaying and ensuring the stability of the power equipment during the lifting process. At the same time, the pitching and rotation of the support platform is realized through the ball hinge structure, giving the equipment the ability to adjust the angle, thereby meeting the flexibility requirements of multi-angle alignment installation inside the power equipment. 2. This utility model, through its positioning mechanism, effectively avoids the problem of displacement or shaking of power equipment due to insecure fixing during undulation or angle adjustment. When the power equipment is placed on the support platform, the second drive component is activated, and the second servo motor fixed at the bottom of the support platform drives the gear connected to it to rotate. This gear, through meshing with the inner gear ring, drives the entire gear set to make circumferential motion between the outer and inner rings, thereby driving the rack meshing with it to move linearly towards the center along the through hole of the inner ring. The movement of the rack causes the top moving plate and clamping plate to contract synchronously, applying a uniform and firm clamping force to the power equipment from multiple directions. The anti-slip pad on one side of the clamping plate further increases the friction, thereby firmly locking the power equipment in the center position of the support platform. Even if the undulation mechanism makes complex posture adjustments, the installed equipment can remain stable, greatly improving the installation accuracy and safety. Attached Figure Description

[0016] The present invention will now be described in further detail with reference to the accompanying drawings. These drawings are simplified schematic diagrams, illustrating only the basic structure of the present invention, and therefore only show the components relevant to the present invention.

[0017] refer to Figures 1-4 An undulating mechanism for maintaining the orientation of installed equipment, comprising: The undulation mechanism 1 includes a frame 101 and a support platform 108 directly above it. A support leg 102 is fixedly installed at the bottom of the frame 101, a ball seat 109 is fixedly installed at the bottom of the support platform 108, a mounting base 103 is fixedly installed at the top of the frame 101, and an extension arm 110 is fixedly installed on the outside of the support platform 108. The support platform 108 is connected to the frame 101 through a first drive assembly to realize the adjustment of undulation and angle. The first drive assembly includes a first servo motor 104 fixedly installed inside the mounting base 103 and a ball 107 movably disposed inside the ball seat 109. The output end of the first servo motor 104 is fixedly provided with a large arm 105, and a small arm 106 is rotatably disposed on one side of the large arm 105. The small arm 106 and the ball 107 are fixedly disposed together. When adjusting the height of the undulation, the first drive component is activated, and three sets of first servo motors 104 fixed inside the mounting base 103 drive the upper arm 105 to perform pitching motion. At the same time, the lower arm 106 rotatably connected to it and the ball 107 fixed at its end rotate in multiple angles within the ball seat 109, thereby achieving stable undulation of the support platform 108. When angle adjustment is required, it is only necessary to use one or two sets of servo motors to adjust the angle in all directions. Therefore, this rigid connection mechanical arm structure replaces the flexible sling, fundamentally eliminating swaying and ensuring the stability of the power equipment during the lifting process. At the same time, the pitching and rotation of the support platform 108 are realized through the ball hinge structure, giving the equipment the ability to adjust its angle. A positioning mechanism 2 is installed inside the support platform 108 for positioning the electrical equipment on the top of the support platform 108. The positioning mechanism 2 includes an inner ring 202 and an outer ring 201 fixedly installed on the inner and outer sides of the support platform 108, respectively. An inner toothed ring 203 is rotatably installed on the lower inner side of the outer ring 201. A rack 205 is movably installed at the top slot of the outer ring 201 through a limiting plate 206. A moving plate 207 is fixedly installed at one top end of the rack 205. A clamping plate 208 is fixedly installed on the top of the moving plate 207. The clamping plate 208 is connected to the support platform 108 through a second drive assembly to achieve relative retraction and extension. The second drive assembly includes a second servo motor 210 fixed to the bottom of the support platform 108, and a gear 204 rotatably disposed between the outer ring 201 and the inner ring 202. The gear 204 corresponds to the rack 205 and is configured for meshing transmission. The gear 204 and the inner gear ring 203 are configured for meshing transmission. One of the gears 204 is fixedly disposed at the output end of the second servo motor 210. When the power equipment is placed on the support platform 108, the second drive assembly is activated. The second servo motor 210, fixed to the bottom of the support platform 108, drives the gear 204 connected to it to rotate. The gear 204, through meshing with the inner gear ring 203, drives the entire gear 204 group to make a circular motion between the outer ring 201 and the inner ring 202, thereby driving the rack 205 meshing with it to move linearly towards the center along the through hole of the inner ring 202. The movement of the rack 205 causes the top moving plate 207 and the clamping plate 208 to retract synchronously, applying a uniform and firm clamping force to the power equipment from multiple directions. The anti-slip pad 209 on one side of the clamping plate 208 further increases the friction, thereby firmly locking the power equipment in the center position of the support platform 108. Even if the undulating mechanism 1 makes complex posture adjustments, the installed equipment can remain stable. A moving mechanism 3 is installed at the bottom of the outrigger 102. The moving mechanism 3 includes a hydraulic cylinder 301 fixedly installed inside the outrigger 102. A foot 302 is fixedly installed at the output end of the hydraulic cylinder 301. A moving wheel 303 is rotatably installed at the bottom of the foot 302. When the entire undulating mechanism 1 needs to be moved, the piston rod of the hydraulic push cylinder 301 extends, pushing the foot 302 and the moving wheels 303 down to contact the ground. The entire mechanism is then supported by the moving wheels 303, allowing it to be easily pushed to the target work position. Upon reaching the designated position, the piston rod of the hydraulic push cylinder 301 retracts, lifting the foot 302 and the moving wheels 303 into the support leg 102, ensuring the bottom of the support leg 102 is directly and firmly on the ground, forming a solid and reliable support foundation. This effectively prevents displacement due to uneven ground or external interference during undulation and angle adjustment operations, ensuring the safety and stability of the installation process.

[0018] Example 1: The support legs 102, ball seats 109 and mounting bases 103 are arranged in three sets in a circular shape, which ensures the overall rigidity of the frame 101 when the equipment is undulating and the angle is adjusted, effectively preventing tilting or shaking. The extension arms 110 are arranged in four in a circular shape. The frame 101 and the support platform 108 are provided with weight reduction grooves inside, which reduces the weight of the mechanism, making it easier to move and transport, and also reducing the load on the drive components, thereby improving the response speed and energy efficiency of the mechanism.

[0019] Example 2: The inner ring 202 has through holes corresponding to the rack 205 and the limiting plate 206. These through holes provide smooth guidance for the radial linear movement of the rack 205. At the same time, the limiting plate 206 is embedded in the through holes, which effectively prevents the rack 205 from deflecting or getting stuck during the movement, ensuring smooth and synchronous clamping action. One side of the clamping plate 208 is provided with an anti-slip pad 209. The anti-slip pad 209 is made of rubber or polyurethane material with a high coefficient of friction. When the clamping plate 208 retracts towards the center to clamp the equipment, the anti-slip pad 209 can closely adhere to the surface of the equipment, greatly increasing the static friction. Even when the undulating mechanism 1 makes large-scale posture adjustments, it can effectively prevent the equipment from sliding or displacing, thereby ensuring the absolute safety of the installation operation.

[0020] Working principle: First, the moving mechanism 3 pushes the entire device to the target work position, and controls the hydraulic push cylinder 301 to retract, so that the outrigger 102 is firmly placed on the ground to form a solid support foundation. Next, the electrical equipment to be installed is hoisted onto the support platform 108, and the second drive assembly is started. The second servo motor 210 drives the gear 204 to rotate. The gear 204, through meshing with the inner gear ring 203, drives the entire gear set to make circumferential motion between the outer ring 201 and the inner ring 202, thereby driving the rack 205, which meshes with it, to move linearly towards the center along the through hole of the inner ring 202. The rack 205 drives the top moving plate 207 and clamping plate 20 8. Synchronous retraction, in conjunction with the anti-slip pad 209, firmly locks the power equipment in the center position of the support platform 108; then, the first drive assembly is activated, and the three sets of first servo motors 104 synchronously drive the boom 105 to perform pitching motion, causing the forearm 106 and ball 107 to rotate within the ball seat 109, realizing the stable undulation of the support platform 108. When angle adjustment is required, by controlling one or two sets of first servo motors 104, the ball hinge structure can be used to realize the all-round angle adjustment of the support platform 108, thereby ensuring that the power equipment always maintains a precise posture during the installation process, and finally completing a safe and efficient installation operation.

Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
