Description

Technical Field

[0001] This utility model relates to the field of trailer traction load technology, and more specifically, to a high-load double roller turntable. Background Technology

[0002] The term "traction saddle" is a general term used in trailer traction systems. Roller turntables have the same function as traction saddles and can be used for non-standard vehicle models such as small tractor trucks. Existing roller turntables typically have horizontally hinged joints or simple inner and outer sleeve connections. Existing mechanisms have weak resistance to both vertical and longitudinal loads, so a roller turntable with high load capacity needs to be designed. Utility Model Content

[0003] To address the above deficiencies, this utility model provides a high-load double roller turntable, thus solving the aforementioned problems.

[0004] To achieve the above objectives, the present invention adopts the following technical solution: A high-load double-roller turntable includes a main beam, and also includes, Support beams are welded to the main beams; The fixing component is divided into an upper part and a lower part for easy assembly; The rotating component is embedded in the fixed component and rotates. The contact surfaces between the rotating component and the fixed component are divided into two: one contact surface has a V-shaped cross-section, and the other contact surface is a plane. The connecting part connects the fixing components to the support beam, linking the upper and lower parts.

[0005] Furthermore, the upper and lower cross sections form a V-shape, and the cross section of the rotating component forms a matching triangle. The upper part restricts the rotating component from moving upward, and the lower part restricts the rotating component from moving downward. The top view of the fixed component is annular.

[0006] Furthermore, the rotating component is a hollow ring with a triangular cross-section. The hollow ring has ball grooves with balls inside, which fill the gap between the fixed component and the rotating component. A connecting ring is installed on the inner wall of the hollow ring and is connected to the hollow ring by connecting bolts. A slewing bearing is installed between the upper surface and the connecting ring.

[0007] Furthermore, the fixing component has an annular cavity with a triangular cross-section.

[0008] Furthermore, a pad is installed on the support beam, and the fixing component can be connected to the support beam through the pad.

[0009] Furthermore, the connecting parts are made of high-strength bolts.

[0010] The beneficial effects of this utility model are: through the cooperation of the fixed component and the rotating component, the horizontal load and the vertical load can be dispersed (traditionally it is single-sided, but this application is double-sided), increasing the contact surface and improving stability; The slewing bearing primarily serves as a vertical load-bearing element, significantly enhancing the vertical load capacity of the fixed components.

Detailed Implementation

[0012] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings.

[0013] This application provides a high-load dual-roller turntable; please refer to [reference needed]. Figures 1-4 Including main beam 1, and also, Support beam 2 is welded to main beam 1; Fixing component 3 is divided into upper part 31 and lower part 32 for easy assembly; Rotating component 4 is embedded in fixed component 3 and rotates. The contact surface between rotating component 4 and fixed component 3 is divided into two parts: one contact surface has a V-shaped cross-section 33, and the other contact surface is a plane. The connecting part 5 connects the fixing component 3 to the support beam 2 and connects the upper part 31 and the lower part 32.

[0014] In practical applications, external loads can be connected to the rotating component 4. To facilitate installation, the components of the rotating component 4 are assembled first, and then the lower part 32 is connected to the support beam 2 through the connecting part 5. After that, the rotating component 4 is installed. At this time, the rotating component 4 is in a rotatable state. Then, the upper part 31 and the lower part 32 are connected through the connecting part 5. The cross-section of the contact surface between the fixed component 3 and the rotating component 4 is set to a horizontal V-shape 33 to prevent the rotating component 4 from moving up and down, thus achieving the purpose of anti-tilting. By setting another contact surface, the longitudinal load capacity can be further improved.

[0015] Reference Figure 1 , Figure 2 , Figure 3 and Figure 4 The cross-sections of the upper part 31 and the lower part 32 form a V-shape 33, and the cross-section of the rotating component 4 forms a triangle 34 that matches it. The upper part 31 restricts the rotating component 4 from moving upward, and the lower part 32 restricts the rotating component 4 from moving downward. The top view of the fixed component 3 is annular.

[0016] In practical applications, the V-shape 33 and the triangle 34 work together to restrict the vertical movement of the rotating component 4 while facilitating its rotation. The top view of the upper part 31 and the lower part 32 is also circular.

[0017] Reference Figure 1 , Figure 2 , Figure 3 and Figure 4 The rotating component 4 is a hollow ring 41 with a triangular cross-section 34. The hollow ring 41 has a ball groove 42 and a ball 43 inside the ball groove 42. The ball 43 fills the gap between the fixed component 3 and the rotating component 4. A connecting ring 44 is installed on the inner wall of the hollow ring 41. The connecting ring 44 is connected to the hollow ring 41 by connecting bolts. A rotary bearing 45 is installed between the upper surface of the upper part 31 and the connecting ring 44.

[0018] In practical applications, the friction between the rotating component 4 and the fixed component 3 can be reduced by the ball groove 42 and the ball 43. The hollow ring 41 is in a rotatable state. It can be connected to the external load by the connecting ring 44. The vertical load capacity can be further increased by the slewing bearing 45.

[0019] Reference Figure 1 , Figure 2 , Figure 3 and Figure 4 The fixing component 3 has an annular cavity 341 with a triangular cross-section 34 inside.

[0020] In practical applications, the annular cavity 341 can effectively improve the structural strength of the fixing component 3 while reducing weight and cost.

[0021] Reference Figure 1 , Figure 2 , Figure 3 and Figure 4 A pad 21 is installed on the support beam 2, and the fixing component 3 can be connected to the support beam 2 through the pad 21.

[0022] In practical applications, the mounting plate 21 allows for the use of fixing components 3 of different sizes.

[0023] Reference Figure 1 , Figure 2 , Figure 3 and Figure 4 The connecting part 5 is a high-strength bolt 51.

[0024] In practical applications, the connection of high-strength bolts 51 can effectively increase the overall connection strength.
