Description

Technical Field

[0001] This utility model relates to the field of crane equipment monitoring technology, and in particular to an automatic stabilization camera device for crane equipment. Background Technology

[0002] In modern industrial production, lifting equipment is widely used in various material handling and loading / unloading operations. To ensure the safety and efficiency of lifting operations, cameras are typically used to monitor the operation of the lifting equipment, providing operators with real-time visual feedback and helping them better observe the lifted goods and the surrounding environment.

[0003] Chinese utility model patent CN212245950U discloses a marine crane hook status monitoring device, which includes a fixed bracket, a connecting shaft, a camera bracket, and a camera. The fixed bracket is fixed to the crane boom and is rotatably connected to the camera bracket via the connecting shaft. The camera is mounted on the camera bracket. The fixed bracket is a U-shaped channel steel, with one end fixedly connected to the crane boom. Two ear plates are vertically fixed to the U-shaped channel steel, each ear plate having a through hole. A sleeve is installed between the two opposing ear plates. The connecting shaft passes through the sleeve from the through hole on one ear plate and exits from the through hole on the other ear plate. A cotter pin is installed at one end of the connecting shaft extending out of the through hole on the ear plate. The above-mentioned marine crane hook status monitoring device can rotate under the weight of the camera, achieving real-time alignment with the hook.

[0004] In the aforementioned utility model patent, the camera bracket of the marine crane hook status monitoring device can only rotate relative to the fixed bracket around the connecting shaft. When the camera is subjected to vibration along the axial direction of the connecting shaft, it cannot be buffered, resulting in problems such as shaking, deformation, and distortion of the image captured by the camera, causing the image captured by the camera to be unstable and interfering with the operator's observation. Utility Model Content

[0005] In view of the shortcomings of the existing technology, the present invention provides an automatic stabilizing camera device for lifting equipment, which solves the problem of unstable images captured by the camera when it is subjected to vibration along the connecting shaft axis.

[0006] According to an embodiment of this utility model, an automatic stabilization camera device for lifting equipment includes a fixed bracket and a camera bracket. The camera bracket is equipped with a camera, and the fixed bracket is equipped with two rotation dampers. Each rotation damper includes a housing and a connecting shaft rotatably disposed within the housing. The two connecting shafts are perpendicular to each other. The fixed bracket is also equipped with a rotatable first rotating frame and a second rotating frame. The first rotating frame and the second rotating frame are fixedly connected to the two connecting shafts one-to-one. A third rotating frame is rotatably connected to the end of the second rotating frame away from the connecting shaft, and the rotation axis of the third rotating frame is perpendicular to the connecting shaft fixedly connected to the second rotating frame. The camera bracket is equipped with a first connecting rod and a second connecting rod that are perpendicular to each other. The first connecting rod is rotatably connected to the end of the first rotating frame away from the connecting shaft, and the second connecting rod is rotatably connected to the end of the third rotating frame away from the second rotating frame.

[0007] Furthermore, the fixing bracket includes a base plate, on which a plurality of through holes are spaced apart.

[0008] Furthermore, the base plate is provided with two support plates spaced apart, the support plates are provided with a first mounting hole and the housing is provided with a first positioning hole aligned with the first mounting hole, and the support plates are also provided with a through hole aligned with the connecting shaft.

[0009] Furthermore, the housing has a receiving cavity for accommodating part of the connecting shaft and the receiving cavity is filled with oil. A stop plate is provided on the inner peripheral wall of the receiving cavity. A rotating plate is sleeved on the portion of the connecting shaft located in the receiving cavity and a through buffer hole is provided on the rotating plate.

[0010] Furthermore, one end of the housing is provided with a removable end cap, which covers the opening of the accommodating cavity.

[0011] Furthermore, the camera includes a mounting plate, the camera bracket is provided with a second mounting hole, and the mounting plate is provided with a second positioning hole aligned with the second mounting hole.

[0012] Furthermore, the first rotating frame is U-shaped, with its two ends extending to opposite sides of the camera bracket. The opposite sides of the camera bracket are respectively provided with the first connecting rod, and the two first connecting rods are rotatably connected to the two ends of the first rotating frame one-to-one.

[0013] Furthermore, the second rotating frame has a third connecting rod at one end away from the connecting shaft, and the third rotating frame has a third mounting hole that cooperates with the third connecting rod.

[0014] Compared with existing technologies, this utility model has the following beneficial effects: By using two rotary dampers on a fixed support, one rotary damper's connecting shaft, first rotating frame, and first connecting rod on the camera bracket are sequentially rotatably connected, while the other rotary damper's connecting shaft, second rotating frame, third rotating frame, and second connecting rod on the camera bracket are sequentially rotatably connected. This allows the camera bracket to rotate in any direction relative to the fixed support. When the lifting equipment vibrates, the camera mounted on the camera bracket remains vertically downward under its own weight, causing the two connecting shafts to rotate and drive the camera bracket to deflect relative to the fixed support. At the same time, the rotary dampers can buffer the vibration of the connecting shafts, thereby reducing the shaking caused by the camera being subjected to vibrations in various directions and improving the stability of the camera's captured image. This solves the technical problem of unstable images captured by the camera when subjected to vibrations along the connecting shaft axis in existing monitoring devices, and produces the technical effect of mitigating the impact of lifting equipment vibration on the camera and keeping the captured image stable.

[0020] The technical solution of this utility model will be further described below with reference to the accompanying drawings and embodiments.

[0021] like Figures 1 to 4As shown in the figure, this utility model embodiment proposes an automatic stabilization camera device for lifting equipment, which is installed on the lifting equipment to monitor the working status of the lifting equipment, so that the operator can better observe the lifted goods and the surrounding situation.

[0022] Please refer to Figure 1 and Figure 2 The automatic stabilization camera device for the lifting equipment includes a fixed bracket 1 and a camera bracket 2. A camera 21 is mounted on the camera bracket 2. Two rotation dampers 3 are mounted on the fixed bracket 1. Each rotation damper 3 includes a housing 31 and a connecting shaft 32 rotatably disposed within the housing 31. The two connecting shafts 32 are perpendicular to each other. The fixed bracket 1 also includes a rotatable first rotating frame 4 and a second rotating frame 5. The first rotating frame 4 and the second rotating frame 5 are fixedly connected to the two connecting shafts 32 one-to-one. A third rotating frame 6 is rotatably connected to the end of the second rotating frame 5 away from the connecting shaft 32, and the rotation axis of the third rotating frame 6 is perpendicular to the fixed connection with the second rotating frame 5. The camera bracket 2 is connected to the connecting shaft 32. It is provided with a first connecting rod 22 and a second connecting rod 23 that are perpendicular to each other. The first connecting rod 22 is rotatably connected to the end of the first rotating frame 4 away from the connecting shaft 32. The second connecting rod 23 is rotatably connected to the end of the third rotating frame 6 away from the second rotating frame 5. When the two connecting shafts 32 rotate respectively, the camera bracket 2 can rotate in any direction relative to the fixed bracket 1. The rotation damper 3 buffers the rotation of the camera bracket 2, so that the camera 21 mounted on the camera bracket 2 remains vertically downward while swinging slowly, which helps to improve the stability of the image captured by the camera 21.

[0023] Specifically, after the automatic stabilizing camera device for lifting equipment provided in this embodiment is installed on the lifting equipment, the connecting shaft 32, the first rotating frame 4, and the first connecting rod 22 on the camera bracket 2 of one of the rotary dampers 3 are sequentially rotatably connected, and the connecting shaft 32, the second rotating frame 5, the third rotating frame 6, and the second connecting rod on the camera bracket 2 of the other rotary damper 3 are sequentially rotatably connected, allowing the camera bracket 2 to rotate in any direction relative to the fixed bracket 1. When the lifting equipment vibrates during operation, the camera 21 mounted on the camera bracket 2 remains vertically downward under its own weight, causing the two connecting shafts 32 to rotate respectively and drive the camera bracket 2 to deflect relative to the fixed bracket 1. During the rotation of the connecting shafts 32, the rotary damper 3 provides buffering, thereby reducing the shaking caused by vibrations in various directions to the camera 21 and improving the stability of the images captured by the camera 21. The automatic stabilization camera device for lifting equipment provided in this embodiment can mitigate the impact of lifting equipment vibration on the camera 21, keeping the image captured by the camera 21 stable, thereby facilitating the operator's observation and operation of the lifting equipment.

[0024] like Figure 2 As shown, the fixed bracket 1 includes a base plate 11, on which a plurality of through holes 12 are spaced apart. The automatic stabilization camera device for lifting equipment provided in this embodiment is installed on the boom or other positions of the lifting equipment via bolts or other connecting components disposed within the through holes 12, ensuring a reliable connection between the base plate 11 and the lifting equipment, maintaining the stable position of the camera 21 on the lifting equipment, and preventing the fixed bracket 1 from detaching from the lifting equipment during operation.

[0025] In detail, two support plates 13 are spaced apart on the base plate 11. Each support plate 13 has a first mounting hole, and the housing 31 has a first positioning hole aligned with the first mounting hole. The support plate 13 also has a through hole aligned with the connecting shaft 32. The two support plates 13 are spaced apart on the base plate 11, and each support plate 13 has the first mounting hole for mounting the rotary damper 3. The housing 31 has a first positioning hole aligned with the first mounting hole. Bolts are inserted into the first mounting hole and the first positioning hole, and nuts are used to lock the rotary damper 3 onto the support plate 13. After the rotary damper 3 is mounted on the support plate 13, the connecting shaft 32 passes through the through hole to facilitate the connection of the first rotating frame 4 or the second rotating frame 5 to the corresponding connecting shaft 32. This ensures the structural stability of the automatic stabilization camera device for the lifting equipment while facilitating its assembly.

[0026] Please combine Figure 3 and Figure 4 The housing 31 has a accommodating cavity 33 for accommodating a portion of the connecting shaft 32, and the accommodating cavity 33 is filled with oil. A stop plate 34 is provided on the inner peripheral wall of the accommodating cavity 33. A rotating plate 35 is sleeved on the portion of the connecting shaft 32 located within the accommodating cavity 33, and the rotating plate 35 has a through buffer hole 36. By filling the accommodating cavity 33 with a certain viscosity of oil, when the connecting shaft 32 rotates, the oil located between the rotating plate 35 and the stop plate 34 can only pass through the buffer hole 36, thereby providing damping for the rotation of the rotating plate 35 and achieving the purpose of buffering the rotation of the camera bracket 2.

[0027] In this embodiment, one end of the housing 31 is provided with a detachable end cap 37, which covers the opening of the accommodating cavity 33. The detachable end cap 37 at the end of the housing 31 allows the accommodating cavity 33 to be opened by removing the end cap 37, facilitating the injection of oil with a viscosity suitable for the working environment of the automatic stabilization camera device of the lifting equipment into the accommodating cavity 33, and also facilitating the replacement of the oil in the accommodating cavity 33.

[0028] Please refer to Figure 2 The camera 21 includes a mounting plate 24. The camera bracket 2 has a second mounting hole, and the mounting plate 24 has a second positioning hole aligned with the second mounting hole. The mounting plate 24 on the camera 21 is used to mount the camera 21 onto the camera bracket 2. The camera 21 is fixed to the camera bracket 2 by passing bolts through the second mounting hole and the second positioning hole in sequence and tightening them with nuts, ensuring a secure connection between the camera 21 and the camera bracket 2.

[0029] like Figure 1 and Figure 2 As shown, the first rotating frame 4 is U-shaped, with both ends extending to opposite sides of the camera bracket 2. The camera 21 has corresponding first connecting rods 22 on opposite sides, and each connecting rod 22 is rotatably connected to one end of the first rotating frame 4. By arranging the first rotating frame 4 in a U-shape, and after combining it with the camera bracket 2, with both ends extending to the sides of the camera bracket 2 and rotatably connected to the first connecting rods 22, the stability of the connection between the first rotating frame 4 and the camera bracket 2 is improved.

[0030] Specifically, the second rotating frame 5 has a third connecting rod at the end away from the connecting shaft 32, and the third rotating frame 6 has a third mounting hole that mates with the third connecting rod. The second rotating frame 5 and the third rotating frame 6 are rotatably connected through the engagement of the third connecting rod and the third mounting hole, ensuring a secure connection between the two while allowing the third rotating frame 6 to rotate smoothly relative to the second rotating frame 5, thus ensuring that the camera 21 maintains a downward shooting direction.

[0031] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of this utility model without departing from the spirit and scope of the technical solutions of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
