[0047] The embodiments of the technical solutions of the present application will be described in detail below with reference to the drawings. The following embodiments are only used to more clearly illustrate the technical solutions of the present application, and therefore only serve as examples, and cannot limit the protection scope of the present application.
[0048] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this application belongs; the terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the present application; the terms "comprising" and "having", and any variations thereof, as used in the specification and claims and the aforementioned drawings, are intended to cover not exclusive inclusions.
[0049] In order to alleviate the impact of the sensor arranged on the final actuator, such as a spreader, on the device to reduce the damage, on the one hand, according to some embodiments of the present application, a bracket assembly is provided, Figures 1-2 An exploded schematic view of the bracket assembly according to some embodiments of the present application is shown.
[0050] In conjunction with Figure 1 and Figure 2 , the bracket assembly 100 includes an outer housing 1, a sensor mounting 2, a first buffer assembly 3 and / or a second buffer assembly 4, for example, in Figure 1 the embodiment shown, only the first buffer assembly 3 is included, and Figure 2 the embodiment shown includes both the first buffer assembly 3 and the second buffer assembly 4. The outer housing 1 includes a side wall 11 and a top wall 12, and the side wall 11 encloses a receiving cavity 10 in the outer housing. The sensor mounting 2 is mounted in the receiving cavity 10, and the sensor is fixed in the outer housing 1 through the sensor mounting 2. The first buffer assembly 3 is mounted on the sensor mounting 2, and when the bracket assembly 100 is assembled on a component (such as a spreader), the first buffer assembly 3 is arranged in a vertical direction (i.e. the direction shown by the arrow h in the figure).
[0051] Taking the embodiment shown in Figure 2 as an example, the second buffer assembly 4 is mounted on the sensor mounting 2, and when the bracket assembly 100 is assembled on a component (such as a spreader), the second buffer assembly 4 is arranged in a horizontal direction (i.e. in the horizontal plane perpendicular to the direction shown by the arrow h).
[0052] Since the impact on the final actuator, such as the hoist, when hoisting mainly includes a relatively large impact in the lifting (height) direction (i.e. the direction shown by the arrow h in the figure) and / or a relatively small impact in the horizontal direction. By designing the first buffer assembly 3 and / or the second buffer assembly 4, the larger impact and the smaller impact can be reduced, so as to alleviate the impact on the sensor arranged on the hoist to reduce the damage of the device and increase the service life of the device, and then improve the stability of the whole hoisting system.
[0053] In the description of the embodiments of the present application, the technical terms "first", "second", etc. are only used to distinguish different objects, and cannot be understood as indicating or implying relative importance or implicitly indicating the number, specific order or primary and secondary relationship of the indicated technical features.
[0054] In this document, the term "embodiment" means that the specific features, structures or characteristics described in connection with the embodiment can be included in at least one embodiment of the present application. The appearance of this phrase in various places in the specification does not necessarily mean that all the embodiments refer to the same embodiment, nor are they independent or alternative embodiments to other embodiments. It is explicitly and implicitly understood by those skilled in the art that the embodiments described herein can be combined with other embodiments.
[0055] Figure 6 A side view of the sensor mounting according to some embodiments of the present application is shown, according to some embodiments of the present application, the sensor mounting 2 has a waist-shaped hole 20 on the sensor mounting 2, the sensor mounting 2 is installed in the accommodating cavity 10 through the waist-shaped hole 20, and the waist-shaped hole 20 allows the sensor mounting 2 after installation to be fine-tuned in the accommodating cavity 10.
[0056] Figure 4 A perspective view of the bracket assembly according to another embodiment of the present application is shown, Figure 5 An exploded view of the bracket assembly according to another embodiment of the present application is shown, in combination with Figures 4-6As shown, according to some embodiments of the present bracket assembly, a mounting support plate 13 is further provided in the accommodating cavity 10, and the mounting support plate 13 is installed on the side wall 11 of the outer shell 1, and has a first mounting hole 131 and a second mounting hole 132. The sensor mounting component 2 is also provided with a third mounting hole 21, and the waist-shaped hole 20 is connected to the first mounting hole 131 through a fastener, and the second mounting hole 132 is connected to the third mounting hole 21 through a fastener. The sensor mounting component 2 in the connected state is rotatable with the axial direction of the second mounting hole 132 and the third mounting hole 21 (that is, the axial direction of the fastener connected to the second mounting hole 132, that is, the third mounting hole 21) as the rotation axis, and the waist-shaped hole 20 cooperates with the fastener to limit the rotation range of the sensor mounting component 2 relative to the mounting support plate 13. It will be appreciated that in some specific embodiments, during use, the fasteners connecting the waist-shaped hole 20 and the first mounting hole 131 are tightened to restrict the rotation of the sensor mounting member 2 relative to the mounting support plate 13. During adjustment, the fasteners connecting the waist-shaped hole 20 and the first mounting hole 131 are loosened to allow the installed sensor mounting member 2 to be fine-tuned within the accommodating cavity 10. This configuration allows the sensor mounting member 2 to have a certain degree of freedom of movement, meeting the needs of on-site fine-tuning of the sensor.
[0057] According to some embodiments of the bracket assembly, the sensor mounting member 2 has a wing portion 22. When the bracket assembly 100 is mounted on a component (such as a hanger), the wing portion 22 is arranged horizontally. The sensor is mounted on the wing portion 22 via bolts 23, and the first buffer assembly 3 is a coil spring arranged around the outer periphery of the bolts.
[0058] Further, see Figure 6 According to some embodiments of the bracket assembly, the bolt 23 is a tapping bolt having a threaded section 231 and a smooth section 232. The wing portion 22 has a through hole 220, and the tapping bolt passes through the through hole 220 to connect with the sensor. The first buffer assembly 3 includes a first coil spring 31 and a second coil spring 32. In the assembled state, the first coil spring 31 is disposed on the periphery of the smooth section 232 between the wing portion 22 and the tapping bolt head 233, and the second coil spring 32 is disposed on the periphery of the smooth section 232 between the wing portion 22 and the installed sensor. By using the tapping bolt, the tapping bolt passes through the through hole 220 in the smooth section 232. Ideally, the elastic change caused by the friction between the bolt and the hole can be ignored. In this way, the impact on the sensor mounted on the bolt 23 can be effectively reduced. In a specific embodiment, the smooth section 232 of the driving bolt is the sum of the length of the first coil spring 31 and the second coil spring 32 and the thickness of the wing plate portion 22, and the length of the threaded section 231 of the driving bolt is the thread length of the sensor fixing hole. Such a configuration can further improve the vibration reduction efficiency of the first buffer assembly 3. In some specific embodiments, such asFigure 6 As shown in the state, before the sensor is assembled, a nut 234 is arranged at the lower part of the plug bolt for fixing the second coil spring.
[0059] In some embodiments, a coil spring is also arranged between the connection of the sensor mounting member 2 and the mounting plate 13 to further achieve damping. In some embodiments, a nut 235 is also arranged between the connection of the sensor mounting member 2 and the mounting plate 13 before the sensor is mounted, for fixing the coil spring between the connection of the sensor mounting member 2 and the mounting plate 13. In other embodiments, a spring and / or a shock pad can also be arranged between the mounting plate 13 and the inner side of the accommodating cavity 10.
[0060] According to some embodiments of the present support assembly, the second damping assembly 4 is a shock pad. In some embodiments, the shock pad is a pad made of an impact-absorbing material such as rubber.
[0061] Further, according to some embodiments of the present support assembly, the support assembly 100 is applied to a spreader, and when the support assembly 100 is assembled on the spreader, the shock pad is arranged along the extension direction of the spreader and / or the shock pad is arranged along the direction perpendicular to the extension direction of the spreader, so as to absorb the relatively small impact in the horizontal plane.
[0062] Figure 3 A perspective view of the outer shell of the support assembly according to another embodiment of the present application is shown. In some embodiments of the present support assembly, the top wall 12 is inclined upwardly from the side wall 11 towards the inner side of the outer shell to form a guide section 120. Figure 4 As shown, in some embodiments of the present support assembly, the top wall 12 has a section with a circular arc transition towards the inner side of the outer shell upwardly from the side wall 11, forming a circular arc section 121. Due to the characteristics of the wire rope connection, the spreader of the container handling crane will produce a pendulum-like reciprocating motion in actual work, which will cause the collision with the adjacent container and the possible hanging and pulling off of the entire support assembly during the reciprocating motion. In the existing design, a relatively thick steel plate is selected to cope with the risk of collision. The applicant has found through research on the operation situation that the scratching mainly occurs during the lifting stage of the spreader. The outer shell top wall 12 with the guide section 120 and / or the circular arc section 121 is designed according to the possible scratching direction during the lifting stage of the spreader, so as to reduce the impact of the collision with the adjacent container and the possible hanging and pulling off of the entire support assembly. Figure 7As shown, during the ascent of the spreader, when there is a tendency to collide with the container, the guide section 120 and / or the arc section 121 can guide the spreader to avoid in the direction indicated by the arrow a, thereby avoiding the risk of the entire bracket assembly being pulled off due to the collision. In some suitable embodiments, if the spreader is scratched during the descent stage, a guide section 120 and / or an arc section 121 can be designed on the bottom wall below the bracket assembly 100. In the description of the embodiments of the present application, the term "and / or" is merely a description of the association relationship of associated objects, indicating that there can be three relationships. For example, A and / or B can represent three situations: A exists alone, A and B exist at the same time, and B exists alone.
[0063] On the other hand, according to some embodiments of the present application, a sling is also provided, such as Figure 9 As shown, the sling 200 provided according to some embodiments of the present application is provided with a bracket assembly 100 as described in one or more of the previous embodiments.
[0064] In some specific embodiments, the bracket assembly 100 is mounted on the sling 200 by a connection method such as welding.
[0065] On the other hand, according to some embodiments of the present application, a method for designing a bracket assembly is also provided. Figure 8 A schematic flow chart of a method for designing a bracket assembly according to some embodiments of the present application is shown, which includes the following steps:
[0066] First, roughly determine the installation position of the sensor;
[0067] Then, step a. according to the installation position of the sensor on the installed component, determine whether an anti-hanging structure is required. If so, an anti-hanging structure is designed on the outer housing of the bracket assembly. If not, proceed to the next step;
[0068] Then, step b. according to the installation position of the sensor on the mounted component, determine whether an adjustable structure is required. If so, an adjustable structure is designed on the sensor mounting member of the bracket assembly. If not, proceed to the next step;

If so, a first vertically arranged buffer assembly and / or a horizontally arranged second buffer assembly are designed within the bracket assembly based on the impact direction. If not, proceed to the next step.

The adjustable structure design is used for the sensor which needs to be adjusted, and the shock reduction structure design is used for the sensor which needs to reduce the impact, so as to meet the requirements of different sensors on the sling, and on the basis of saving costs as much as possible, the effective protection of the sensor is realized.
[0073] In summary, the design method of the anti-hanging, shock reduction, adjustable support and cover is to design supports with different functions according to requirements and different installation positions.

[0083] In other specific embodiments, the upper unit and / or the lower unit is composed of n units connected in series, and the total stiffness coefficient is
[0084] In some other specific embodiments, when the upper unit and / or the lower unit is a spring, the formula for calculating the spring constant of a single spring is: Where G is the rigidity modulus (when it is carbon spring steel wire, G = 79000N / mm 2 When it is stainless steel wire, G = 71000N / mm 2 . ) ; d is the wire diameter (mm); D m is the median diameter (mm); N c is the effective number of coils of the coil spring, and its calculation formula is Where t is the pitch of the coil spring, H0 is the free length of the coil spring, and N2 is the number of turns of the coil spring that are tightened and ground flat at both ends.

[0087] The guide angle θ is calculated using the following formula:
[0088]
[0089] Among them, l d is the maximum misalignment of container stacking, l h In some specific embodiments, the height of the top wall of the outer shell is d It is determined according to the actual situation of the dock. Usually it can be set to 9cm to 11cm according to experience. h The height can be determined by comprehensively considering the thickness of the plate used in the bracket assembly and the rigidity of the bracket assembly.
