Description

Carbon steel skeleton brake disc attached with PA material Technical Field The invention relates to the field of civil rammed earth construction machinery, in particular to a carbon steel skeleton brake disc attached with PA materials. Background When the dynamic compactor is used for compacting the ground, the rammer reciprocates, wherein a brake disc of the winch plays an important role in the repeated lifting process of the rammer. At present, the existing brake disc products mostly use metal structures as stress materials, the whole brake disc is large in quality, difficult to process, high in production cost, difficult to install, poor in toughness and easy to crack and jump when working on a construction site with high strength for a long time, and therefore production site efficiency is affected. Aiming at the problems, a carbon steel skeleton brake disc attached with PA materials is provided. Disclosure of Invention The technical scheme is that the carbon steel skeleton brake disc with the PA material is characterized in that the PA material, the carbon steel skeleton, a brake disc pressure groove, tooth-shaped connection, a wheel type skeleton and a connecting boss are externally attached, the PA material is cast and attached to the carbon steel skeleton, the front surface and the back surface of the PA material are respectively provided with the brake disc pressure groove with central symmetry, the carbon steel skeleton is provided with tooth-shaped connection, the carbon steel skeleton is provided with the wheel type skeleton, the wheel type skeleton is provided with the connecting boss, and the wheel type skeleton is in threaded connection with a target mechanism through the designed connecting boss. Compared with the prior art, the PA material carbon steel skeleton brake disc has the advantages of being capable of greatly reducing weight and processing difficulty of the brake disc, high in strength and toughness, capable of bearing 2200NM torsion at the maximum rotating speed within a normal deformation range, capable of normally working at 150 ℃, safe and reliable, capable of losing working capacity immediately before a carbon steel skeleton is broken when the attached PA material fails due to fatigue, capable of protecting a hoisting mechanism, simple to maintain after the attached PA material fails completely, capable of conducting injection molding on the carbon steel skeleton again after heat treatment is carried out on the attached PA material coating, capable of greatly saving materials and improving service efficiency of the PA material. Drawings FIG. 1 is a three-dimensional schematic diagram of a carbon steel skeleton brake disc with PA material attached; fig. 2 is a three-dimensional schematic diagram of a carbon steel skeleton of a PA material-attached carbon steel skeleton brake disc of the present invention. In the figure, the PA material is attached to the outside 101, the carbon steel skeleton is attached to the outside 102, the brake disc pressure groove is attached to the outside 103, the tooth-shaped connection is formed on the outside 104, the wheel-shaped skeleton is attached to the outside 105, and the boss is attached to the outside 106. Detailed Description The invention is further described below with reference to the drawings and the detailed description. The invention provides a technical scheme that a carbon steel skeleton brake disc with attached PA materials comprises an external attached PA material 101, a carbon steel skeleton 102, a brake disc pressure groove 103, tooth-shaped connection 104, a wheel type skeleton 105 and a connection boss 106, wherein the external attached PA material 101 is cast and attached to the carbon steel skeleton 102, the front surface and the back surface of the external attached PA material 101 are respectively provided with the brake disc pressure groove 103 with central symmetry, the carbon steel skeleton 102 is provided with the tooth-shaped connection 104, the carbon steel skeleton 102 is provided with the wheel type skeleton 105, the wheel type skeleton 105 is provided with the connection boss 106, and the wheel type skeleton 105 is in threaded connection with a target mechanism through the designed connection boss 106. During production, the carbon steel skeleton 102 is processed, PA material is injection molded and adhered in a mold, during installation, the toothed connection 104 designed on the carbon steel skeleton 102 is inserted in alignment with the central gear shaft of the hoisting mechanism, the wheel-type skeleton 105 is in threaded connection with a target mechanism through the designed connection boss 106, and during failure, the adhered PA material is cut off and heat treated, and the carbon steel skeleton is injection molded again.
