AI Technical Summary
When the existing movable beam structures bear long-term tensile and torque, the structural strength is insufficient and the welding parts or connecting plates are prone to cracking.
Improve the structure of the movable beam connecting plate into a groove-shaped piece, and connect the movable beam fixture through a bolt and nut assembly to increase the stress surface of the movable beam square tube and enhance structural strength.
By increasing the stress surface and improving the connection structure, the strength of the movable beam is significantly enhanced, and tensile and torque can be more effectively withstand the tensile and torque, avoiding cracks in the welded parts or the connecting plate.

Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of a carrier frame, and particularly relates to a detachable movable beam connection structure of a carrier frame. Background Art
[0002] The existing movable beam structure is composed of a flat plate lapped with a square tube profile. Only one surface of the flat plate can be welded, and only the cross section of the square tube can be welded. The structural strength is general and is not sufficient to withstand long-term tensile and torsional forces. The welded part or the connecting plate is prone to cracking. Content of the Utility Model
[0003] The purpose of the utility model is to provide a detachable movable beam connection structure of a carrier frame to solve the problems put forward in the above background art.
[0004] To achieve the above purpose, the utility model provides the following technical solution: A detachable movable beam connection structure of a carrier frame, wherein the movable beam is welded and composed of a movable beam square tube and two movable beam connecting plates. The movable beam connecting plates are located on both sides of the movable beam square tube. Movable beam fixing parts are arranged on both sides of the movable beam. The movable beam connecting plates are connected with the movable beam fixing parts through bolt and nut assemblies. The movable beam connecting plates are channel-shaped parts.
[0005] The technical effects and advantages of the utility model: The structure of the movable beam connecting plate is mainly improved. It is improved from the original flat plate to a channel-shaped part. The upper and lower two surfaces of the movable beam square tube profile are fully welded with the channel-shaped part, and the front and rear two surfaces are spot welded, which increases the stress surface and enhances the structural strength of the movable beam. Description of the Drawings
[0006] Figure 1 It is a schematic diagram of the utility model;
[0007] Figure 2 It is the Figure 1 top view schematic diagram of the utility model.
[0008] In the figure: 1 movable beam square tube, 2 movable beam connecting plate, 3 movable beam fixing part, 4 bolt and nut assembly. Detailed Embodiment
[0009] Next, the technical solutions in the embodiments of the utility model will be clearly and completely described in conjunction with the drawings in the embodiments of the utility model. Obviously, the described embodiments are only a part of the embodiments of the utility model, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the utility model without creative efforts shall fall within the protection scope of the utility model.
[0010] The utility model provides as Figure 1-2A detachable movable beam connection structure of a load-bearing vehicle frame is shown, including that the movable beam is composed of a movable beam square tube 1 and two movable beam connecting plates 2 welded together. The movable beam connecting plates 2 are located on both sides of the movable beam square tube 1. Movable beam fixing parts 3 are arranged on both sides of the movable beam. The movable beam connecting plates 2 are connected to the movable beam fixing parts 3 through bolt and nut assemblies 4. The movable beam connecting plates 2 are channel-shaped parts. The channel-shaped parts can enable full welding on the upper and lower surfaces of the movable beam square tube 1 and spot welding on the front and rear surfaces of the movable beam square tube 1, increasing the stress-bearing surface between the movable beam connecting plates 2 and the movable beam square tube 1 and enhancing the strength of the movable beam.
[0011] Finally, it should be noted that the above are only the preferred embodiments of the present invention and are not used to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, for those skilled in the art, they can still modify the technical solutions recorded in the foregoing embodiments, or perform equivalent replacements for some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.
