Description

Technical Field

[0001] This invention relates to the field of civil engineering rammed earth construction machinery, specifically a carbon steel frame brake disc with PA material attached. Background Technology

[0002] When a dynamic compaction machine compacts the ground, the hammer moves back and forth. The winch's brake disc plays an important role in the repeated lifting of the hammer.

[0003] Currently, most existing brake disc products use metal structures as the load-bearing material. The overall brake disc is heavy, difficult to process, has high production costs, is difficult to install, and generally has poor toughness. Under long-term high-intensity construction site operations, it is prone to cracking and breaking, thus affecting the efficiency of production sites.

[0004] To address the aforementioned issues, a carbon steel frame brake disc with PA material attached is proposed. Summary of the Invention

[0005] To solve the above-mentioned technical problems, the present invention provides the following technical solution: a carbon steel frame brake disc with attached PA material, characterized in that: externally attached PA material, a carbon steel frame, brake disc pressure grooves, toothed connections, a wheel-shaped frame, and connecting bosses; the externally attached PA material is cast and attached to the carbon steel frame; the externally attached PA material has centrally symmetrical brake disc pressure grooves designed on both the front and back surfaces; the carbon steel frame has toothed connections; the carbon steel frame has a wheel-shaped frame; the wheel-shaped frame has connecting bosses; the wheel-shaped frame is threadedly connected to the target mechanism through the designed connecting bosses.

[0006] Compared with existing technologies, the carbon steel frame brake disc made of PA material has the following advantages: it can greatly reduce the weight and processing difficulty of the brake disc; the device has high strength and toughness, and can reach a maximum speed of 2200 r / min and withstand a torque of 2200 NM within the normal deformation range; the device has high temperature resistance and can work normally at 150℃; the device is safe and reliable, and when the attached PA material fails due to fatigue, it will break before the carbon steel frame, thus preventing immediate loss of working capacity and protecting the hoisting mechanism; after the attached PA material completely fails, the device is easy to repair. After removing the PA material coating and heat-treating, the carbon steel frame can be re-molded, which greatly saves materials and improves its efficiency. Attached Figure Description

[0010] The present invention will be further described below with reference to the accompanying drawings and specific embodiments.

[0011] This invention provides a technical solution: a carbon steel frame brake disc with attached PA material, comprising externally attached PA material 101, a carbon steel frame 102, a brake disc pressure groove 103, a toothed connection 104, a wheel-shaped frame 105, and a connecting boss 106; the externally attached PA material 101 is cast and attached to the carbon steel frame 102; the externally attached PA material 101 has centrally symmetrical brake disc pressure grooves 103 on both its front and back surfaces; the carbon steel frame 102 has a toothed connection 104; the carbon steel frame 102 has a wheel-shaped frame 105; the wheel-shaped frame 105 has a connecting boss 106; the wheel-shaped frame 105 is threadedly connected to the target mechanism through the designed connecting boss 106.

[0012] During production, the carbon steel frame 102 is first machined, and then PA material is injected into the mold. During installation, the toothed connection 104 on the carbon steel frame 102 is aligned with the central toothed shaft of the hoisting mechanism and inserted. The wheel-shaped frame 105 is threadedly connected to the target mechanism through the designed connecting boss 106. In case of failure, the attached PA material is removed and heat-treated, and the carbon steel frame is re-injected and molded.
