Description

Technical Field

[0001] The embodiments of this application relate to the field of mechanical tooling technology, and in particular to lifting tooling used in radar and a combination of tooling and radar for lifting operations. Background Technology

[0002] During the production and testing phase of radar products, they need to be placed on a vibration table for vibration testing to verify their reliability. The radar under test (for example, a radar weighing approximately 27 kg) is usually characterized by irregular shape, off-center center of gravity, and lack of dedicated lifting points.

[0003] In existing technologies, there are two main methods of handling radar: The first is manual handling, which typically requires three operators working together: two to support and hold the radar product, and the third to assemble and disassemble the screws. This method is not only labor-intensive and inefficient, but also presents safety hazards due to the limited operating space around the vibration table and the presence of multiple people standing. Furthermore, manual handling easily leads to product damage. The second method is direct lifting with slings. Because radar has an irregular shape and lacks dedicated lifting points, directly using slings easily results in tilted or angled lifting, potentially damaging delicate components on the radar surface (such as antennas). There is also a significant risk of the radar falling off during high-altitude movement, posing an extremely high safety hazard.

[0004] Therefore, how to adapt to the irregular shape of the radar, provide stable and reliable lifting points, and effectively avoid skewed or tilted lifting are the technical problems that urgently need to be solved. Utility Model Content

Detailed Implementation

[0016] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the various embodiments of this application will be described in detail below with reference to the accompanying drawings. Those skilled in the art will understand that many technical details have been presented in the embodiments of this application to facilitate better understanding. However, the technical solutions claimed in this application can be implemented even without these technical details and various variations and modifications based on the following embodiments. The division of the following embodiments is for ease of description and should not constitute any limitation on the specific implementation of this application. The following embodiments can be combined with and referenced by each other without contradiction.

[0017] During the production and testing phase of radar products, they need to be placed on a vibration table for vibration testing to verify their reliability. The radar under test (for example, a radar weighing approximately 27 kg) is usually characterized by irregular shape, off-center center of gravity, and lack of dedicated lifting points.

[0018] In existing technologies, there are two main methods of handling radar: The first is manual handling, which typically requires three operators working together: two to support and hold the radar product, and the third to assemble and disassemble the screws. This method is not only labor-intensive and inefficient, but also presents safety hazards due to the limited operating space around the vibration table and the presence of multiple people standing. Furthermore, manual handling easily leads to product damage. The second method is direct lifting with slings. Because radar has an irregular shape and lacks dedicated lifting points, directly using slings easily results in tilted or angled lifting, potentially damaging delicate components on the radar surface (such as antennas). There is also a significant risk of the radar falling off during high-altitude movement, posing an extremely high safety hazard.

[0019] Therefore, how to adapt to the irregular shape of the radar, provide stable and reliable lifting points, and effectively avoid skewed or tilted lifting are the technical problems that urgently need to be solved.

[0020] In view of this, this application provides a hoisting fixture for radar and a fixture and radar assembly for hoisting operations. Through structural optimization design, the radar can be hoisted onto the vibration table as a whole, reducing manual handling and avoiding the operation of using slings to pull and lift at an angle. At the same time, it reduces the difficulty and danger of high-altitude operations on irregularly shaped objects.

[0021] The following is an exemplary description of a lifting fixture used in radar according to an embodiment of this application.

[0022] like Figure 1 As shown, Figure 1 This is a schematic diagram of a lifting fixture for radar provided in one embodiment of this application. The lifting fixture includes: a first support frame 1 and a second support frame 2.

[0023] The first support frame 1 is arranged around the radar turntable; the second support frame 2 is placed under the radar's support arm; the first support frame 1 and the second support frame 2 are fixedly connected by detachable connectors, and after assembly, they form a ring-shaped hoisting structure that adapts to the shape of the radar, which, together with the hoisting equipment, enables the overall hoisting of the radar.

[0024] In one possible embodiment, the detachable connector 5 is a screw; the connection positions of the first support frame 1 and the second support frame 2 are provided with threaded holes that are compatible with the screw, so as to realize the fastening connection of the first support frame 1 and the second support frame 2 by screws.

[0025] For example, screws are used as detachable connectors 5. The corresponding connection positions of the first support frame 1 and the second support frame 2 are pre-set with threaded holes adapted to the screws. By tightening the screws, the first support frame 1 and the second support frame 2 can be securely connected into a rigid integral structure.

[0026] For example, the embodiments of this application do not specifically limit the type of screw; for example, the screw may be a hexagonal structure, a cylindrical head structure, or a pan head structure.

[0027] In one possible embodiment, the first support frame 1 has a ring frame structure; the inner contour of the first support frame 1 is adapted to the outer contour of the radar turntable to fit the side of the turntable for positioning, and the support platform 6 of the first support frame 1 supports the weight of the radar turntable.

[0028] For example, the first support frame 1 can be configured as a wrap-around structure, with its inner shape adapted to the outer periphery of the radar turntable, so as to cover the turntable from all sides, thereby ensuring that it fits the side of the turntable for precise positioning and avoiding displacement of the radar relative to the tooling during hoisting.

[0029] For example, the support platform 6 is embedded in the inner wall of the annular frame of the first support frame 1. The inner contour of the first support frame 1 is adapted to the outer contour of the radar turntable, ensuring that the support platform 6 can be accurately aligned with the preset step at the bottom of the radar turntable, thereby supporting the weight of the radar turntable.

[0030] In one possible embodiment, the top of the first support frame 1 is provided with four lifting point structures 4, which are used to cooperate with the lifting device to keep the radar in a horizontal state during hoisting.

[0031] At the top of the first support frame 1, four lifting point structures 4 are provided for connecting external lifting tools (e.g., hooks, shackles, etc.). These lifting points are symmetrically distributed to ensure the stability of the center of gravity and the horizontal position of the radar during lifting.

[0032] Understandably, the encircling structure of the first support frame 1 allows the lifting point to be moved upwards, providing a stable and reliable lifting fixture structure for radars without dedicated lifting points. This avoids skewed or oblique lifting and reduces the risks of high-altitude operations. Specifically, since the main structure of the first support frame 1 is an encircling structure, its inner contour is precisely machined to match the outer contour of the radar turntable. This mechanism design allows it to support translational entry from the outside in, tightly wrapping around the radar turntable. The geometry of the turntable's sides is used for radial positioning and constraint, and it connects with the second support frame 2 to prevent the radar 3 from swaying or rotating in the horizontal plane during lifting.

[0033] In one possible embodiment, the second support frame 2 has a plate-like structure; the upper surface of the second support frame 2 is provided with a support surface adapted to the lower surface of the radar arm to support the weight of the radar arm.

[0034] For example, the second support frame 2 has a plate-like structure, with a support surface on its upper surface that matches the shape of the lower surface of the radar arm, used to bear the main weight of the radar arm. This structural design enables uniform stress distribution and avoids local stress concentration.

[0035] For example, when the first support frame 1 and the second support frame 2 are connected by screws, they together form a rigid lifting fixture that securely holds the radar within it. Specifically, the first support frame 1 and the second support frame 2 jointly bear the weight of the radar, and the first support frame 1 can be responsible for restricting the horizontal movement and rotation of the radar. During lifting, the force of the lifting device acts on the lifting point of the first support frame, is transmitted to the connection point through the frame structure of the first support frame 1, and then works together with the second support frame 2 to lift the radar safely and smoothly.

[0036] Understandably, the second support frame 2 can be used to bear the weight of the radar, that is, to provide axial support. Specifically, the second support frame 2 has a plate-like structure, and its upper surface is designed as a support surface adapted to the lower surface of the radar arm. The second support frame 2 is placed below the radar arm, directly supporting most of the radar's weight and transferring the force to the lifting device through the structure.

[0037] In one possible embodiment, the first support frame 1 and the second support frame 2 are made of aluminum alloy or stainless steel.

[0038] Understandably, considering that the tooling needs to possess sufficient strength, rigidity, and lightweight characteristics to facilitate operation and ensure safety, the first support frame 1 and the second support frame 2 are preferably made of aluminum alloy or stainless steel. Aluminum alloy can effectively reduce the weight of the tooling while meeting mechanical performance requirements; stainless steel provides better corrosion resistance and is suitable for more complex working environments.

[0039] Taking aluminum alloy as an example, the aluminum alloy material can be of the 6061 type. Aluminum alloy material can combine strength and lightweight characteristics, which can meet the load requirements of a 27kg radar and reduce the weight of the tooling itself.

[0040] An embodiment of this application proposes a lifting fixture for radar, including a first support frame 1 and a second support frame 2. The first support frame 1 is arranged around the radar turntable, and the second support frame 2 is placed below the radar's support arm. The first support frame 1 and the second support frame 2 are fixedly connected by detachable connectors, forming a ring-shaped lifting structure adapted to the radar's shape after assembly. This allows for the overall lifting of the radar in conjunction with a lifting device. Through this optimized structural design, the radar can be hoisted onto the vibration table as a whole, reducing manual handling and avoiding the operation of pulling and lifting at an angle with slings. It also reduces the difficulty and danger of high-altitude operations on irregularly shaped objects.

[0041] like Figure 2 As shown, Figure 2 This is a schematic diagram of a tooling and radar assembly for hoisting operations provided in one embodiment of this application. The tooling and radar assembly for hoisting operations includes: a radar 3 and a hoisting tooling.

[0042] The radar 3 includes a radar turntable and a support arm; the hoisting fixture includes a first support frame 1 and a second support frame 2; the first support frame 1 is arranged around the radar turntable, and the second support frame 2 is placed under the radar's support arm; the first support frame 1 and the second support frame 2 are fixedly connected by detachable connectors, and after assembly, they form a ring-shaped hoisting structure that adapts to the shape of the radar 3, so as to cooperate with the hoisting equipment to achieve the overall hoisting of the radar.

[0043] For a detailed description of the hoisting equipment, please refer to the above embodiments; it will not be repeated here.

[0044] As one possible implementation, the inner diameter of the first support frame 1 is adapted to the outer diameter of the radar turntable, and the inner peripheral wall of the first support frame 1 is provided with an annular groove adapted to engage with the radial step of the turntable. The first support frame 1 is sleeved around the outer periphery of the turntable and positioned by the annular groove and the radial step.

[0045] As one possible approach, Radar 3 has an irregular shape and no dedicated lifting points.

[0046] As one possible implementation, Radar 3 weighs 27 kg.

[0047] The following section will describe in detail how to use a hoisting fixture provided in the embodiments of this application to carry out hoisting operations.

[0048] First, place the second support frame 2 stably directly below the support arm of the radar 3, ensuring its supporting surface is in complete contact with the lower surface of the support arm. Then, slide the first support frame 1 inwards, tightly wrapping it around the radar turntable, ensuring its inner contour fits the turntable side. It is then secured to the turntable step via the support platform 6 for load-bearing and to prevent the radar from falling off. At this point, the connecting holes on the first support frame 1 and the threaded holes on the second support frame 2 should be aligned. Screws are passed through the connecting holes and screwed into the threaded holes, tightening them to secure the first support frame 1 and the second support frame 2, forming a ring-shaped lifting structure adapted to the radar's shape. This structure utilizes the step and support arm under the radar turntable as support and positioning references, achieving stable holding of the radar. A lifting device (e.g., a hook) is attached to the lifting point on the top of the first support frame 1; simultaneously, the lifting device is slowly activated, and the lifting fixture and radar 3 are lifted smoothly as a whole. Due to the reasonable design of the lifting points and the sufficient rigidity of the fixture structure, swaying and tilting during the lifting process are effectively avoided. Finally, after hoisting the radar 3 to the designated position on the vibration table and placing it stably, remove the connecting screws, first remove the first support frame 1, and then remove the second support frame 2, thus completing the installation of the radar 3 on the vibration table.

[0049] In summary, in the embodiments of this application, since the radar 3 has an irregular shape, there are no lifting points for the radar 3 in this embodiment. Therefore, it is possible to move the lifting points upwards and use a wrap-around method to hoist the radar 3 as a whole. Utilizing the steps on the lower surface of the radar turntable and the lower surface of the support arm, a wrap-around structure is used to connect the first support frame 1 and the second support frame 2 to form an integral structure for hoisting. Based on this, the embodiments of this application can hoist the radar 3 as a whole onto the vibration table, reducing manual handling and avoiding the operation of using slings to pull or lift at an angle. At the same time, it reduces the difficulty and danger of high-altitude operations on irregularly shaped objects.
