Description

Technical Field

[0001] The utility model relates to the technical field of mechanical installation, in particular to a rotatable installation structure. Background Technique

[0002] A crane is a device that realizes the lifting, slewing and hoisting of goods through a hydraulic lifting and telescoping system. However, during the operation process, due to the influence of vision and obstacles, the operator cannot accurately judge the distance between the boom and the object, which greatly affects the accurate operation of the operator and even causes a collision between the boom and the object. Therefore, in the field of lifting equipment, in order to avoid safety accidents caused by misoperation due to unclear situations, it is relatively common to set monitoring devices such as cameras on the boom above the lifting hook of the lifting equipment so that the operator can observe the surrounding working environment centered on the lifting hook in the cab.

[0003] For mobile cranes such as crawler cranes and truck cranes, since the angle and length of the boom need to be adjusted according to different working conditions, if the camera is directly installed on the boom, when the angle of the boom changes, the camera cannot automatically adjust the angle, and there is a problem that the camera cannot capture the surrounding working environment centered on the lifting hook, which may also cause safety accidents.

[0004] In the prior art, Chinese Patent CN 217478860U provides a crane hook camera installation structure in which the camera can automatically adjust the angle according to the change of the swing arm angle, including a shaft and a swing arm.

[0028] As Figures 1 to 3 shown, the rotatable mounting structure of the example of the present utility model includes a first connecting member 11, a second connecting member 12, a rotary damper 13, a first mounting member 14, and a second mounting member 15. Among them, the first connecting member 11 is used for fixedly connecting to a mechanical device, the second connecting member 12 is detachably connected to the first connecting member 11, the rotary damper 13 is sleeved on the second connecting member 12, the first mounting member 14 is respectively detachably connected to the rotary damper 13 and the second connecting member 12, the second mounting member 15 is detachably connected to the first mounting member 14, and the second mounting member 15 is used for detachably connecting to a mounting device 101.

[0029] The rotatable mounting structure according to the embodiment of the present utility model has the rotational damper 13 directly sleeved on the second connecting member 12. Therefore, the mounting and positioning structure of the rotational damper 13 is simple and compact, and each component of the entire rotatable mounting structure adopts a detachable connection method, making the assembly, disassembly, and maintenance of the entire rotatable mounting structure simple and convenient. The structure is simple, the appearance is small and delicate. Moreover, the torque of the rotational damper 13 can be adjusted according to the weight of the mounting device 101 such as a camera on the mounting structure, and the second mounting member 15 can be customized according to different mounting devices 101, so that the rotatable mounting structure has good adaptability. The mounting device 101 is directly connected to the rotational damper 13 through the first mounting member 14, so that when the mounting device 101 such as a camera rotates with the rotational damper 13, there is a damping feeling, reducing the vibration of the mounting device 101 such as a camera and making the mounting device 101 such as a camera work more stably.

[0030] Specifically, as Figure 2 and Figure 3 shown, in this embodiment, the first connecting member 11 is a connecting column, the second connecting member 12 is a connecting shaft, one end of the connecting shaft is inserted into the connecting column, and the rotational damper 13 and the first mounting member 14 are sleeved on the connecting shaft. Specifically, in this embodiment, one end of the connecting shaft is threadedly connected to the connecting column, and a locking member 16 is sleeved on one end of the connecting shaft. The locking member 16 is used to lock the connecting shaft on the connecting column. Specifically, in this embodiment, the connecting column can be welded to the mechanical device, such as on the boom of a crane. One end of the connecting shaft inserted into the connecting column is a screw rod structure, and the locking member 16 is a nut or a screw nut sleeved on the screw rod structure and meshing with the screw rod structure. The specific structures and the mutual connection structures of the first connecting member 11 and the second connecting member 12 in the above structural form are simple and compact, and the assembly, disassembly, and maintenance are convenient.

[0031] Specifically, as Figure 2 and Figure 3As shown, in this embodiment, the connecting shaft is provided with a mounting portion 121. The mounting portion 121 is a plate-like structure sleeved on the connecting shaft, and one side of the rotary damper 13 is detachably connected to one side of the mounting portion 121. Specifically, in this embodiment, one side of the first mounting member 14 abuts against the other side of the rotary damper 13, and one side of the second mounting member 15 is fixedly connected to a position near the bottom of the other side of the first mounting member 14. The other side of the second mounting member 15 is used for detachably connecting the mounting device 101. Obviously, by providing the plate-like mounting portion 121, the mounting and fixing of the rotary damper 13 can be made stable and reliable, and the structure is as simple and compact as possible. By providing the first mounting member 14 and the second mounting member 15 to connect the mounting device 101 such as a camera to the rotary damper 13, the mounting device 101 can rotate with the rotary damper 13 under its own gravity and be in a horizontal state to ensure the normal operation of the mounting device 101. The structure is simple, compact, stable and reliable.

[0032] Specifically, as Figure 2 and Figure 3 shown, in this embodiment, both the first mounting member 14 and the second mounting member 15 are plate-like structures. The top width of the first mounting member 14 is smaller than its bottom width, and the second mounting member 15 is detachably connected to a position near the bottom of the first mounting member 14. The first mounting member 14 and the second mounting member 15 with the above structural form are simple and compact in structure, and the top width of the first mounting member 14 is small, which can avoid the first mounting member 14 occupying a large space when rotating with the rotary damper 13 and avoid interference with other parts of mechanical devices such as cranes. Moreover, the bottom width of the first mounting member 14 is wider, which is convenient for the second mounting member 15 to be stably and reliably fixedly connected to the first mounting member 14, so as to ensure that the mounting device 101 can be stably and reliably arranged on the rotatable mounting structure.

[0033] Specifically, as Figure 2 and Figure 3 shown, in this embodiment, a limiting member 17 and a fixing assembly 18 are sleeved on the other end of the connecting shaft. The limiting member 17 is sleeved on the connecting shaft and is detachably connected to the side of the first mounting member 14, and the fixing assembly 18 is arranged on the side of the limiting member 17 away from the first mounting member 14. The fixing assembly is used to fix the limiting member. It is easy to understand that by providing the limiting member 17 and the fixing assembly 18, the stability and reliability of the entire rotatable mounting structure can be greatly improved, and the overall structure of the mounting structure is made as simple and compact as possible.

[0034] Specifically, as Figure 2 and Figure 3As shown, in this embodiment, the fixing component 18 includes a gasket 181 and a fixing pin 182. The gasket 181 is sleeved on the connecting shaft and abuts against the limiting member 17. The fixing pin 182 is perpendicular to the axis of the connecting shaft and is inserted into the end of the connecting shaft to fix the gasket 181, thereby fastening and limiting the limiting member 17. Specifically, in this embodiment, the limiting member 17 includes a limiting plate 171 and a limiting shaft 172 connected to the limiting plate 171. The limiting plate 171 and the limiting shaft 172 are provided with coaxial limiting holes, and the connecting shaft passes through the limiting holes, with a simple and compact structure and convenient for installation, disassembly and maintenance.

[0035] Specifically, as Figure 1 shown, in this embodiment, the rotatable mounting structure further includes a horizontal detection member 19. The horizontal detection member 19 is arranged on the first mounting member 14 and is used to detect whether the mounting device 101 connected to the second mounting member is in a horizontal state. Specifically, the horizontal detection member 19 can send an alarm message to remind the operator to correct and process when the mounting device 101 such as a camera is out of horizontal alignment, making the mounting device 101 such as a camera work more reliably.

[0036] The working process of the rotatable mounting structure of the embodiment of the present utility model is as follows:

[0037] As Figure 4 shown, after the rotatable mounting structure of the embodiment of the present utility model and the device 101 to be mounted are installed and adjusted, they are in a horizontal state under the action of the overall gravity of the rotatable mounting structure and the mounting device 101, that is, the state required for the mounting device 101 to work.

[0038] When the entire rotatable mounting structure tilts due to the movement of the mechanical part it is fixed to, such as the pitching operation of the boom of a crane, at the moment of tilting, the state of the rotatable mounting structure is as Figure 5 shown, the mounting device 101 rotates with the rotary damper 13 under the action of gravity so as to always maintain the state as Figure 4 shown, that is, it is always in the working state. During this process, the rotary damper 13 acts as a rotating shaft and plays a role in stabilizing the mounting device 101 such as a camera and reducing the vibration of the mounting device 101.

[0039] Due to certain reasons, after the mounting device 101 tilts, it cannot return to the state as Figure 4 shown. At this time, the horizontal detection member detects that the mounting device 101 is in an inclined state and sends an alarm signal to remind the operator that the mounting device 101 is out of horizontal alignment and the mounting device 101 may not be working properly. The operator can perform corresponding repairs according to the specific situation.

[0040] According to the above embodiments, it can be seen that the rotatable mounting structure involved in the utility model has a simple and compact mounting and positioning structure for the rotary damper, and the entire rotatable mounting structure is simple and convenient to assemble and disassemble and maintain. In addition, the torque of the rotary damper can be adjusted according to the weight of the equipment installed on the mounting structure, and the second mounting member can be personalized according to the different installed equipment, thereby making the rotatable mounting structure have good adaptability.

[0041] The above is only a specific implementation of the utility model, but the protection scope of the utility model is not limited thereto. Any changes or substitutions that can be easily thought of by a person skilled in the art within the technical scope disclosed by the utility model should be included in the protection scope of the utility model. Therefore, the protection scope of the utility model shall be subject to the attached claims.
