Description

Technical Field

[0001] The utility model relates to a pipe bundle and cable connection and installation component, in particular to a heavy truck gantry structure. Background Art

[0002] The heavy-duty truck gantry is mainly used to connect the pipe bundles and cables between the main vehicle and trailer. The existing heavy-duty truck gantry has 8 fixing points to the frame, which is cumbersome to install, has no weight-reducing design, has poor damage resistance, and frequently cracks the welds. In addition, the heavy-duty truck gantry structure is installed with many pipe bundles and cables, which has poor maintainability and is not beautiful. Utility Model Content

[0003] The purpose of the utility model is to realize a heavy truck gantry structure which has the advantages of light weight, good rigidity, strong fatigue damage resistance and easy disassembly and assembly.

[0004] The utility model is realized by the following technical solutions:

[0005] A heavy-duty truck gantry structure includes two brackets 1 and a U-shaped pipe 2. The two brackets 1 are respectively connected to the two ends of the pipe 2. A plate 3 is welded between the horizontal pipe and the two vertical pipes of the pipe 2 by intermittent welding, wherein a gap 5 is left at the welding position. Two small brackets 4 are fixed on the end face of the plate 3, and the plate 3 is designed with weight-reducing holes 6.

[0006] The two ends of the pipe 2 connected to the bracket 1 are flat.

[0007] The small bracket 4 is welded to the end surface of the plate 3 .

[0008] The lower end of the bracket 1 is provided with a bolt hole connected to the frame longitudinal beam.

[0009] The utility model has the advantages of simple structure, low manufacturing cost, convenient assembly and disassembly, light weight, strong fatigue damage resistance and strong practicality, and is suitable for promotion. BRIEF DESCRIPTION OF THE DRAWINGS

[0010] Figure 1 It is a structural diagram of the present utility model. DETAILED DESCRIPTION

[0011] like Figure 1 As shown, the utility model is a new heavy-duty truck gantry structure, including two brackets 1, a U-shaped pipe 2, the two ends of the pipe 2 are flat, which is convenient for connection with the bracket 1 structure, a plate 3 is welded to the pipe 2, and two small brackets 4 are welded to the end face of the plate 3.

[0012] During specific use, there are 4 bolt holes on the bracket 1, the two bolt holes at the lower end are used to connect the bracket 1 to the frame longitudinal beam, and the two bolt holes at the upper end are used to connect the bracket 1 to the connecting pipe 2; the pipe 2 and the plate 3 are connected by welding, and a gap 5 is left at the welding position. The purpose of not performing welding is to avoid high rigidity and stress concentration caused by all welding, and weight-reducing holes 6 are designed on the plate 3, which can reduce the weight of the entire gantry and allow the pipe bundle and cable to pass through it for use; the small bracket 4 is welded to the plate 3, mainly used to fix the air pipe.

[0013] The utility model has a simple structure and consists of four components in total, with low manufacturing cost. The gantry structure and the longitudinal beam are connected by bolts, which is convenient for disassembly and assembly. Three large weight-reducing holes are made on the plate 3 to reduce the total mass of the gantry structure. The pipe 2 and the plate 3 are intermittently welded, which reduces the risk of stress concentration and enhances the ability to resist fatigue damage.
