Description

Technical Field

[0001] This utility model relates to the field of engineering structural components, specifically to a wind-resistant cantilever with an overload torque limiting structure. Background Technology

[0002] In modern engineering construction and equipment application, cantilever structures are widely used due to their unique extension characteristics. Taking the cantilever of outdoor high-altitude work equipment as an example, when working in strong winds, the cantilever not only has to bear the weight of itself and the equipment it carries, but also has to resist the huge torque and bending moment generated by the wind.

[0003] Existing wind-resistant cantilever structures are mostly straight rod structures, and are fixed to the corresponding frame using a single fastening bolt and nut. This type of wind-resistant cantilever structure generally has the following problems: First, traditional cantilever structures often use enhanced material strength and optimized shape design to improve wind resistance, but this method has limited effect under extreme strong winds and will significantly increase manufacturing costs and structural weight, leading to increased equipment energy consumption.

[0004] Secondly, most cantilever structures lack effective overload protection mechanisms. When wind speeds are too high or the operating load exceeds the design capacity, the internal torque of the cantilever increases sharply, but the load cannot be unloaded in time. This can easily lead to structural deformation, connector breakage, or even overall collapse, seriously threatening personnel safety and the normal operation of equipment. Therefore, developing a cantilever structure with efficient overload torque limiting function and excellent wind resistance has become an urgent technical challenge. Utility Model Content

[0005] The purpose of this invention is to provide a wind-resistant cantilever with an overload torque limiting structure to address the deficiencies mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] A wind-resistant cantilever with an overload torque limiting structure includes a fixed support. A horizontally arranged cantilever rod is fixedly installed at the center of the front side of the fixed support. The cantilever rod is a hollow structure, with a central hollow rod at its center. The rear end of the central hollow rod is fixedly installed on the front side of the fixed support. Multiple sets of internal reinforcing support rods arranged in a ring at equal intervals are fixedly installed between the central hollow rod and the cantilever rod. Multiple overload torque limiting components arranged in a ring at equal intervals are fixedly installed between the fixed support and the cantilever rod. Each overload torque limiting component includes a first diagonal brace and a second diagonal brace installed between the fixed support and the cantilever rod. Multiple reinforcing rods are fixedly installed between the first diagonal brace and the corresponding second diagonal brace. A honeycomb support plate is fixedly installed between the first diagonal brace and the cantilever rod.

[0008] Preferably, the cross-section of the cantilever rod is annular, and the inner reinforcing support rods are arranged radially;

[0009] This feature allows the cantilever to maintain its strength while reducing its weight.

[0010] Preferably, a front fixing seat is fixedly installed at the front end of the cantilever rod, and external components are fixedly installed on the front fixing seat.

[0011] Preferably, the fixed support, the cantilever rod and the first diagonal brace, and the fixed support, the cantilever rod and the second diagonal brace all form a triangle;

[0012] This design utilizes the stability properties of a triangle to improve the overall compressive strength.

[0013] Preferably, the honeycomb support plate has a mesh-like plate structure, and the length of the second diagonal brace is greater than the length of the first diagonal brace.

[0014] Preferably, bolt plates are fixedly installed at the ends of the first diagonal brace, the second diagonal brace, and the honeycomb support plate near the cantilever rod, and the bolt plates are fixedly connected to the cantilever rod by a plurality of fastening bolts;

[0015] This setting facilitates on-site installation operations.

[0016] Preferably, bolt seats are fixedly installed at the ends of the first and second diagonal braces near the fixed support, and fasteners that pass through the bolt seat and the fixed support and are used for fixing are provided in the bolt seats;

[0017] Preferably, the fastener includes a hexagonal protrusion abutting against one side of the bolt seat, a forward stud fixedly installed at the end of the hexagonal protrusion passing through the bolt seat and the fixed support, a reverse stud fixedly installed at the end of the forward stud, an elastic washer sleeved on the forward stud, a clamping sleeve sleeved between the reverse stud and the forward stud, a forward nut and a reverse nut respectively threaded onto the forward stud and the reverse stud, and the reverse nut sequentially presses the clamping sleeve, the forward nut and the elastic washer against the other side of the fixed support;

[0018] The above two settings can stably fix the bolt seat and prevent it from loosening.

[0019] Compared with the prior art, the beneficial effects of this utility model are:

[0020] 1. This utility model uses a hollow cantilever rod with a central hollow rod and inner reinforcing support rods arranged in a ring at equal intervals inside. The cantilever rod has a ring-shaped cross-section and the inner reinforcing support rods are arranged radially. This reduces the weight of the cantilever rod while maintaining its structural strength. Compared with traditional cantilever rods, it effectively reduces manufacturing costs and equipment energy consumption, and avoids the operational burden caused by excessive structural weight.

[0021] 2. This utility model sets up multiple overload torque limiting components arranged in a ring at equal intervals between the fixed support and the cantilever rod. Utilizing the structure composed of the first diagonal brace, the second diagonal brace, and the reinforcing rod, the fixed support, cantilever rod, and diagonal brace form a triangle. By leveraging the stability characteristics of the triangle, the overall compressive strength is improved. When encountering strong winds or excessive operating loads, it can effectively resist torque and bending moment, prevent structural deformation and connector breakage, and ensure personnel safety and normal equipment operation.

[0022] 3. This utility model achieves convenient on-site installation and operation by installing a honeycomb support plate between the first diagonal brace and the cantilever rod, and by using specially designed fasteners to connect the diagonal brace and the fixed support, while ensuring the stability of the connection and the anti-loosening effect. The mesh structure of the honeycomb support plate reduces weight while ensuring support strength, and the special fasteners can effectively prevent the connection from loosening, extend the service life of the cantilever, and reduce maintenance costs.

[0031] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0032] Please see Figures 1-4 This utility model provides a technical solution: a wind-resistant cantilever with an overload torque limiting structure, including a fixed support 1. A horizontally arranged cantilever rod 10 is fixedly installed at the center of the front side of the fixed support 1. The cantilever rod 10 is a hollow structure. A central hollow rod 12 is provided at the center of the cantilever rod 10. The rear end of the central hollow rod 12 is fixedly installed on the front side of the fixed support 1. Multiple sets of inner reinforcing support rods 13 arranged in a ring at equal intervals are fixedly installed between the central hollow rod 12 and the cantilever rod 10. The inner reinforcing support rods 13 are arranged radially, so that the cantilever rod 10 can be reduced in weight while maintaining high structural strength, effectively reducing material costs and equipment operating energy consumption, and solving the problem of increased weight and energy consumption caused by strengthening materials in traditional cantilever systems.

[0033] like Figure 1 and Figure 2 As shown, multiple overload torque limiting components 2 are fixedly installed between the fixed support 1 and the cantilever 10 in a ring-shaped arrangement at equal intervals. The overload torque limiting components 2 include a first diagonal brace 20 and a second diagonal brace 22 installed between the fixed support 1 and the cantilever 10. Multiple reinforcing rods 24 are fixedly installed between the first diagonal brace 20 and the corresponding second diagonal brace 22. A honeycomb support plate 21 is fixedly installed between the first diagonal brace 20 and the cantilever 10. The fixed support 1, the cantilever 10 and the first diagonal brace 20, and the fixed support 1, the cantilever 10 and the second diagonal brace 22 all form triangles. With the help of the stability characteristics of triangles, the compressive strength of the overall structure is significantly improved. When encountering strong winds or excessive operating loads, it can effectively resist torque and bending moment, prevent deformation of the cantilever structure and breakage of connecting parts, ensure the safety of equipment and personnel, and make up for the deficiency of traditional cantilever lacking an effective overload protection mechanism.

[0034] In this embodiment, a front mounting base 11 is fixedly installed at the front end of the cantilever rod 10, and external components are fixedly installed on the front mounting base 11 by fastening bolts, so that the front mounting base 11 provides a fixed installation position.

[0035] like Figure 1 and Figure 2As shown, the length of the second diagonal brace 22 is greater than the length of the first diagonal brace 20, thus achieving multi-point fixed support on the cantilever rod 10; the honeycomb support plate 21 has a mesh-like plate structure, and the cross-section of the cantilever rod 10 is annular, which can effectively reduce the wind resistance coefficient and reduce the force of wind on the cantilever.

[0036] Specifically, bolt plates 23 are fixedly installed at the ends of the first diagonal brace 20, the second diagonal brace 22, and the honeycomb support plate 21 near the cantilever rod 10. The bolt plates 23 are fixedly connected to the cantilever rod 10 by multiple fastening bolts, which facilitates on-site installation.

[0037] It is worth noting that bolt seats 25 are fixedly installed at the ends of the first diagonal brace 20 and the second diagonal brace 22 near the fixed support 1. Fasteners 3, which pass through the bolt seat 25 and the fixed support 1 and are used for fixing, are provided inside the bolt seat 25. The fastener 3 includes a hexagonal protrusion 30 abutting against one side of the bolt seat 25. A forward-oriented stud 31, passing through the bolt seat 25 and the fixed support 1, is fixedly installed at the end of the hexagonal protrusion 30. A reverse-oriented stud 32 is fixedly installed at the end of the forward-oriented stud 31. An elastic washer 33 is fitted on the forward-oriented stud 31. A clamping sleeve 35 is fitted between the reverse-oriented stud 32 and the forward-oriented stud 31. The reverse stud 32 is threaded with a forward nut 34 and a reverse nut 36 respectively. The reverse nut 36 presses the clamping sleeve 35, the forward nut 34 and the elastic washer 33 against the other side of the fixed support 1 in sequence. The external threads on the surfaces of the forward stud 31 and the reverse stud 32 have opposite directions of rotation. By using the cooperation of the hexagonal protrusion 30, the forward stud 31, the reverse stud 32, the elastic washer 33, the clamping sleeve 35, the forward nut 34 and the reverse nut 36, the bolt seat 25 and the fixed support 1 are stably fixed and prevented from loosening. This ensures that the cantilever rod 10 structure is firmly connected, reduces the frequency of maintenance and lowers maintenance costs.

[0038] When using the wind-resistant cantilever with overload torque limiting structure of this utility model, firstly, the fixed support 1 is firmly installed on the support structure to ensure that it is installed firmly and in the correct position. Then, the cantilever rod 10 is connected to the fixed support 1 through multiple overload torque limiting components 2 arranged in a ring at equal intervals.

[0039] When installing the overload torque limiting component 2, the first diagonal brace 20 and the second diagonal brace 22 are placed near the bolt seat 25 at the end of the fixed support 1. Fasteners 3 are passed through the bolt seat 25 and the fixed support 1. The forward nut 34 and the reverse nut 36 are tightened, and the elastic washer 33 and the clamping sleeve 35 are used to fix them firmly. At the same time, the first diagonal brace 20, the second diagonal brace 22 and the honeycomb support plate 21 are fixed to the cantilever rod 10 through the bolt plate 23 and the fastening bolts, thus completing the installation of the cantilever body.

[0040] Afterwards, the external components that need to be mounted are installed on the front fixed seat 11 at the front end of the cantilever 10 using fastening bolts. During the operation of the cantilever, when encountering strong winds or excessive load that causes an increase in torque, the overload torque limiting component 2 uses the triangular stability characteristics to resist torque and bending moment, ensuring the safety of equipment and personnel.

[0041] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely preferred examples and are not intended to limit the utility model.
