Description

Technical Field

[0001] The utility model relates to an anti-wear fixing device for crossed pipelines, belonging to the technical field of new energy engineering machinery. Background Art

[0002] The application of new energy systems in the field of engineering machinery is usually accompanied by the use of high-power drive motors, high-power motor controllers, and multiple groups of power batteries. It usually operates under harsh conditions of high voltage and large current, and a large amount of heat is generated during operation, requiring additional high-power cooling units and fans. The complex electric drive and heat dissipation systems result in a large number of high-voltage cables and cooling water pipes arranged crosswise in the system itself. In addition, the main functional devices of the engineering machinery itself further limit the layout of the new energy system for providing power in terms of structure. Therefore, there is usually a certain contact when arranging pipelines within a limited space structure. Different from new energy vehicles, engineering machinery has harsh operating conditions, usually accompanied by continuous strong vibrations. Slight interference may cause very serious wear between pipelines, trigger system failures, and reduce the overall service life of the system.

[0003] Currently, in the field of engineering machinery, tools such as pipeline clamps (two-hole pipe clamps 102, three-hole wire clamps 105) and clamps 103 are usually used to fix high-voltage cables 106 and cooling water pipes 107. As Figure 1 shown, different diameter pipeline clamps (two-hole pipe clamps 102, three-hole wire clamps 105) and clamps 103 are used to fix the pipelines. This method is convenient and fast and has a certain practicality. It is mostly used in scenarios with low space requirements and convenient fixing. When fixing pipelines with a relatively thick diameter and crosswise arrangement, an additional pipeline clamp support 101 (fixed on the frame beam 104) is required for auxiliary fixing, which is not practical when space is limited.
