Description

Technical Field

[0001] The utility model is applicable to the field of metal plate processing and production, and provides a hollow frame cross-section structure of a pickling plate. Background Art

[0002] Existing regulations require that the frames of construction machinery have sufficient strength and rigidity, and that they do not suffer overall damage or excessive deformation when the construction machinery collides or hits, thereby protecting the safety of the driver and the machinery.

[0003] The support frame of construction machinery is welded from pipes of various specifications to improve the bearing capacity of the equipment frame. The pipes used should have sufficient bending resistance.

[0004] The cross-sectional design commonly used in existing pipes is relatively regular, and the material utilization coefficient is low. The bending resistance can only be improved by increasing the cross-sectional size. Increasing the cross-sectional size increases the weight of the cab frame and also increases the space occupied by the frame, blocking the driver's field of vision. Utility Model Content
