Description

Technical Field

[0002] The existing monitoring camera at the front end of the boom has a large swing amplitude and a fast speed when the boom is working, which will drive the spherical monitoring camera at the front end to move quickly, so that the signal of the spherical monitoring camera is not stable enough, it is easy to get stuck, and the monitoring image quality is poor. Therefore, a stabilizer is generally installed at the front end of the boom. The above-mentioned stabilizer is specifically installed with through-axis bolts at both ends of a support body. The through-axis bolts rotate in the support body. The two ends of the through-axis bolts are fixedly connected with side panels for installing the camera, and a damping pad is sandwiched between the side panel and the support body; by utilizing the damping effect between the side panel and the damping pad, the spherical monitoring camera swings slowly to ensure the stability of the signal and improve the monitoring image quality. However, since the boom is a large outdoor working equipment, facing the high temperature and humid working environment, the damping pad is easy to age after a period of use. Therefore, the damping effect of the damping pad is easy to weaken, the service life is short, and it is also troublesome to replace it at high altitude. Utility Model Content

[0019] In order to explain the technical content, structural features and effects achieved by the present invention in detail, the following is a detailed description in conjunction with the implementation modes and the accompanying drawings.

[0020] like Figures 1 to 3As shown, the front-end surveillance camera stabilizer 100 of the utility model comprises a mounting seat 1, a cylinder 2, a planetary reducer 3, a rotating shaft 4 and a connecting bracket 5; the mounting seat 1 is mounted on the front end of the boom, and the cylinder 2 is a cylindrical structure. The cylinder 2 is fixedly connected to the mounting seat 1, and the planetary reducer 3 is arranged in the cylinder 2; the rotating shaft 4 is pivoted to the cylinder 2 and is coaxial with the central axis of the cylinder 2, and one end of the rotating shaft 4 extending into the cylinder 2 is connected to the reduction output end of the planetary reducer 3, and one end of the rotating shaft 4 extending out of the cylinder 2 is fixedly connected to the connecting bracket 5, and the lower end of the connecting bracket 5 is connected to the suspension column 6, and the suspension column 6 is used to install the camera.

[0021] See also Figure 3 and Figure 4 The planetary reducer 3 includes a ring gear 31, a sun gear 32, a plurality of planetary gears 33 and a planet carrier 34. The ring gear 31 is fixedly sleeved on the inner wall of the cylinder 2. The sun gear 32 is pivoted in the cylinder 2 and is coaxial with the central axis of the cylinder 2. In this embodiment, there are three planetary gears 33. The planetary gears 33 are evenly arranged between the sun gear 32 and the ring gear 31 and mesh with the sun gear 32 and the ring gear 31. One end of the planet carrier 34 has three sub-axes 342, and the other end is provided with an output shaft. The sub-axes 342 are pivoted with each planetary gear 33 respectively, and the output shaft of the planet carrier 34 is fixedly connected with the rotating shaft 4. By connecting the output shaft of the planet carrier 34 with the rotating shaft 4, the output speed of the rotating shaft 4 can be greatly reduced by utilizing the high reduction ratio of the planetary reducer 3, thereby effectively reducing the shaking of the camera, ensuring the stability of the signal, and improving the image quality of the monitoring. In this embodiment, the planetary reducer 3 and the rotating shaft 4 are symmetrically arranged at the two ends of the cylinder 2, and the connecting bracket 5 is fixedly connected to the two rotating shafts 4. In this way, the forces of the connecting bracket 5 and the cylinder 2 can be balanced, ensuring the stability of the operation of the stabilizer 100.

[0022] Please see again Figure 3 and Figure 4 A connecting shaft 7 is connected between the sun gears 32 of the two planetary reducers 3. In this way, the two planetary reducers 3 can run synchronously, ensuring the consistency of the movements of both sides of the connecting bracket 5. Bearings 8 are provided at both ends of the cylinder 2, and the rotating shaft 4 is arranged in the inner ring of the bearing 8. By providing the bearing 8, the friction between the rotating shaft 4 and the cylinder 2 can be reduced, the smoothness of operation can be improved, the noise can be reduced, and the connecting bracket 5 can be prevented from being stuck and unable to rotate.

[0023] For example Figure 1 and Figure 2As shown, the connecting bracket 5 includes a bottom plate 51 and two side plates 52. The two side plates 52 are symmetrically arranged at the two ends of the barrel 2, and the upper ends of the two side plates 52 are respectively fixedly connected to the rotating shaft 4 on the same side, and the lower ends of the two side plates 52 are respectively fixedly connected to the two ends of the bottom plate 51 to form a door-shaped structure. The bottom plate 51 is provided with a plurality of mounting holes for mounting the hanging column 6. By providing the two side plates 52, the connecting bracket 5 can be subjected to balanced force, and by providing the bottom plate 51, the assembly and disassembly of the camera can be facilitated, thereby improving the convenience of assembly.

[0024] For example Figure 1 and Figure 3 As shown, lubricating oil is provided inside the cylinder 2. The lubricating oil is butter. By injecting lubricating oil into the cylinder 2, on the one hand, the planetary reducer 3 and the rotating shaft 4 can be lubricated to ensure the smooth operation of the two, and on the other hand, the planetary reducer 3 can be isolated from water to prevent the planetary reducer 3 from oxidation and rust, effectively protecting the planetary reducer 3, thereby extending the service life. Specifically, an oil nozzle 21 is provided on the outside of the cylinder 2, and the oil nozzle 21 is connected to the inside of the cylinder 2. The oil nozzle 21 can be opened or closed. When the oil nozzle 21 is opened, the outside can be connected to the inside of the cylinder 2 through the oil nozzle 21, and the lubricating oil can be squeezed into the inside of the cylinder 2 by high pressure. By providing the oil nozzle 21, lubricating oil can be added to the inside of the cylinder 2 at regular intervals, which is convenient for maintenance, effectively protects the planetary reducer 3, and improves the convenience of maintenance.

[0025] Please see again Figure 1 and Figure 2 The mounting seat 1 includes a mounting plate 11 and a connecting plate 12, both of which are flat plates; the mounting plate 11 is provided with a plurality of connecting holes, through which bolts pass to connect with the front end of the boom. One side edge of the connecting plate 12 is fixedly connected to the mounting plate 11, and the other side edge is fixedly connected to the cylinder 2, and the surface of the connecting plate 12 is perpendicular to the surface of the mounting plate 11, so that the cross section of the mounting seat 1 is a T-shaped structure; the mounting plate 11 and the connecting plate 12 are an integrally formed structure, which can make the structural strength of the mounting seat 1 greater; the surface extension surface of the connecting plate 12 passes through the central axis of the cylinder 2.

[0026] When the front end of the boom rotates or swings rapidly, the boom drives the cylinder 2 to rotate or swing rapidly through the mounting seat 1. At this time, the planetary gear 33 of the planetary reducer 3 in the cylinder 2 rotates around the sun gear 32. Since the deceleration is relatively large, the output shaft of the planetary carrier 34 has a small rotation speed. Therefore, the planetary carrier 34 drives the connecting bracket 5, the suspension column 6 and the camera to rotate at a relatively low speed, and the camera directly rotates back to the lowest point under the action of gravity.

[0027] Compared with the prior art, the utility model sets a planetary reducer 3 in the cylinder 2, so that the reduction output end of the planetary reducer 3 is connected to the rotating shaft 4, and the rotating shaft 4 is connected to the connecting bracket 5, so that when the cylinder 2 follows the swing of the front end fast belt of the boom, the rotation speed of the rotating shaft 4 can be greatly reduced by the planetary reducer 3, so that the swing speed of the camera installed on the connecting bracket 5 is reduced, so that it can achieve the purpose of flexibly following the swing of the boom, and can also achieve damping adjustment, so that the shaking of the camera is effectively reduced, and the signal instability is avoided, so that the image quality of the monitoring can be effectively improved. In addition, the planetary reducer 3 is set inside the cylinder 2, and is protected by the cylinder 2. It can work in a high temperature and humid environment for a long time without aging and has a long service life.

[0028] The above disclosure is only a preferred example of the present invention, and certainly cannot be used to limit the scope of rights of the present invention. Therefore, equivalent changes made according to the scope of the patent application of the present invention still fall within the scope covered by the present invention.
