Description

Technical Field

[0001] This invention relates to the field of lifting machinery, and more particularly to a lifting device for a photoelectric pod. Background Technology

[0002] An electro-optical pod is a hardware system equipped on aircraft for detecting and tracking targets in the air. It typically consists of an airborne stabilization platform and detection equipment mounted on that platform. It possesses functions such as target recognition, line-of-sight stabilization, detection and automatic tracking, and data transmission. It is a crucial component of electro-optical reconnaissance and warning technology and a core piece of equipment for UAV reconnaissance. During take-off and landing operations, existing lifting devices for electro-optical pods usually consist of a lifting plate and an outer frame. The lifting plate directly connects to the electro-optical pod and external equipment, driving the pod's movement. The outer frame surrounds the pod, providing protection as it rises and falls. However, the outer frame and the pod do not share the same load, especially since the lower part of the outer frame has a gap with the pod's outer wall, failing to provide support during the lifting process. Therefore, in the existing structure, when subjected to horizontal forces, the lifting plate, lead screw, and pod resemble a cantilever structure, bearing significant bending moments. To ensure strength and rigidity, the lifting device and pod need to be relatively bulky, affecting usability. Summary of the Invention

[0003] The purpose of this invention is to provide a lifting device for a photoelectric pod, which enables the outer frame to support the lifting process of the photoelectric pod, eliminating the bending moment experienced by traditional lifting devices.

[0004] The technical solution adopted by the present invention to solve the above-mentioned technical problems is as follows: a lifting device for a photoelectric pod, comprising a lifting plate installed on the outer wall of the photoelectric pod and an outer frame suspended around the outside of the photoelectric pod. The outer frame includes an upper frame body and a lower frame body located on the upper and lower sides of the lifting plate, respectively. Multiple frame connecting rods are provided on the lifting plate, and the two ends of the frame connecting rods are respectively connected to the upper frame body and the lower frame body. Multiple support components are also installed on the lifting plate, the upper frame body and the lower frame body. The support components include a pulley rod, a limiting block and a support block. One end of the pulley rod is hinged to the upper frame body. A pulley is installed in the middle of the pulley rod and the pulley rod is connected to one end of a steel wire rope. The limiting block is installed on the lifting plate. When the lifting plate drives the photoelectric pod to move upward relative to the outer frame, the limiting block can contact the pulley and push the pulley to roll on its surface, thereby causing the pulley rod to rotate upward and drive the steel wire rope to move upward. The upper frame body is also equipped with a baffle, which can block the pulley rod and limit its downward rotation range.

[0005] The support block is mounted on the support rod. One side of the support block has an arc surface that matches the outer wall of the photoelectric pod, and the other side has an outer conical surface. The inner wall of the lower frame has an inner conical surface that matches the outer conical surface. The lower frame is connected to one end of the fixed rod. The support rod and the fixed rod are arranged opposite each other. Both the support rod and the fixed rod are hinged to two transition rods to form a parallelogram mechanism. The end of the wire rope away from the pulley support rod is connected to the parallelogram mechanism. When the wire rope drives the parallelogram mechanism to rotate upward, the support rod can drive the support block to move upward and engage in the gap between the photoelectric pod and the lower frame, thereby limiting the displacement of the photoelectric pod relative to the lower frame through the cooperation of multiple support blocks. A spring is connected to the parallelogram mechanism. The two ends of the spring are respectively hinged to two opposite corners of the parallelogram mechanism. When the photoelectric pod moves downward relative to the outer frame, the elastic force of the spring can make the parallelogram mechanism rotate downward.

[0006] Preferably, multiple support components are evenly spaced along the circumference of the optoelectronic pod.

[0007] Preferably, the baffle includes a base plate and two side plates. The upper and lower ends of the side plates are connected to the base plate and the upper frame respectively. The two side plates are arranged opposite to each other, and a gap is formed between the two side plates to accommodate the end of the pulley support rod. The wire rope passes through the through hole of the base plate and is connected to the end of the pulley support rod.

[0008] Preferably, the top of the fixing rod is connected to the lower surface of the lower frame, both the fixing rod and the support rod are vertically arranged, and the end of the wire rope is connected to the middle of the transition rod located above.

[0009] Preferably, the limiting block is installed on the outer wall of the lifting plate by multiple screws.

[0010] According to the above technical solution, the beneficial effects of the present invention are:

[0011] The lifting device provided by this invention allows the support blocks to engage with the gap between the photoelectric pod and the lower frame during use. The use of arc and conical surfaces ensures stable contact. By cooperating with multiple support blocks, the displacement of the photoelectric pod relative to the lower frame is limited. The outer frame then provides support for the lifting process of the photoelectric pod. The traditional cantilever load is changed to a simply supported beam load, eliminating the bending moment experienced by traditional lifting devices and improving the stress conditions of the photoelectric pod under horizontal forces. While maintaining the same strength and stiffness as traditional lifting devices, the safety factor of the photoelectric pod is improved, the stress conditions are improved, and the weight of the product can be effectively reduced, thus improving product reliability.

[0018] Referring to the attached diagram, the specific implementation method is as follows:

[0019] like Figure 1 As shown, a lifting device for a photoelectric pod includes a lifting plate 2 installed on the outer wall of the photoelectric pod 1 and an outer frame suspended around the outside of the photoelectric pod 1. The outer frame includes an upper frame body 3 and a lower frame body 4 located on the upper and lower sides of the lifting plate 2, respectively. Multiple frame connecting rods 5 are threaded through the lifting plate 2, and the two ends of the frame connecting rods 5 are connected to the upper frame body 3 and the lower frame body 4, respectively. During operation, the lifting plate 2 is directly connected to the photoelectric pod 1 and external equipment, driving the photoelectric pod 1 to move. The outer frame rises and falls with the photoelectric pod and provides protection.

[0020] like Figure 2-5 As shown, multiple support components are also installed on the lifting plate 2, the upper frame 3, and the lower frame 4. The multiple support components are evenly spaced along the circumference of the photoelectric pod 1. The support components include a pulley rod 7, a limiting block 10, and a support block 12. One end of the pulley rod 7 is hinged to the upper frame 3. A pulley 6 is installed in the middle of the pulley rod 7, and the pulley rod 7 is connected to one end of the wire rope 8. The limiting block 10 is installed on the outer wall of the lifting plate 2 by multiple screws 11. When the lifting plate 2 drives the photoelectric pod 1 to move upward relative to the outer frame, the limiting block 10 can contact the pulley 6 and push the pulley 6 to roll on its surface, thereby causing the pulley rod 7 to rotate upward and drive the wire rope 8 to move upward.

[0021] like Figure 4 , 5As shown, the upper frame 3 is also equipped with a baffle 9, which can block the pulley support rod 7 and limit its downward rotation range. The baffle 9 includes a base plate and two side plates. The upper and lower ends of the side plates are connected to the base plate and the upper frame 3, respectively. The two side plates are arranged opposite to each other, and a gap is formed between the two side plates to accommodate the end of the pulley support rod 7. The wire rope 8 passes through the through hole of the base plate and is connected to the end of the pulley support rod 7.

[0022] Support block 12 is mounted on support rod 14. One side of support block 12 has an arc surface that matches the outer wall of the photoelectric pod 1, and the other side has an outer conical surface. The inner wall of the lower frame 4 has an inner conical surface that matches the outer conical surface. The lower surface of the lower frame 4 is connected to the top of the fixed rod 13. Support rod 14 and fixed rod 13 are arranged opposite each other and are both vertical. Support rod 14 and fixed rod 13 are both hinged to two transition rods 15 to form a parallelogram mechanism. The end of wire rope 8 away from pulley support rod 7 is connected to the middle of the upper transition rod 15. When wire rope 8 drives the parallelogram mechanism to rotate upward, support rod 14 can drive support block 12 to move upward and engage in the gap between photoelectric pod 1 and lower frame 4, thereby limiting the displacement of photoelectric pod 1 relative to lower frame 4 through the cooperation of multiple support blocks 12.

[0023] like Figure 4 , 5 As shown, a spring 16 is connected to the parallelogram mechanism. The two ends of the spring 16 are hinged to two opposite corners of the parallelogram mechanism. When the photoelectric pod 1 moves downwards relative to the outer frame, the elastic force of the spring 16 causes the parallelogram mechanism to rotate downwards, returning it from the supported state shown in Figure 5 to its original position.
