Rail Dog Spike are mainly used for the connection of rails or backing plates and wooden sleepers, that is, a fastener used to connect rails and sleepers or backing plates and sleepers. Mine spikes are made of hot-rolled steel, and the shape of the lower part of the spike is adapted to the shape of the rail bottom. The surface of the nail rod is smooth and clean, and there is no crack or fold at the connection between the nail head jaw and the nail rod. Among the various railroad spikes, dog spikes and the screw spikes are the most common types.
The Rail Dog Spike is used to fasten T-shaped rail road track to wooden ties, which has an L-shaped head and square shank, and the underside of whose head is sloped to fit the top surface of the rail base. Spikes with various sizes are provided to meet the different requirements of penetrating length of spikes.
Rail Dog Spikes are divided into: 22kg, 24kg, 30kg, etc. according to different types of rails. According to the actual model, it is divided into: 12*120, 8*100, 14*140, etc. Mine railway spikes are mainly divided into two types: hand-made spikes and machine-made spikes. Hand-made road studs are hand-made, and their dimensions are uneven, but they are cheap and generally shipped by ton.
With the rapid development of highway construction, the use of Rail Dog Spike is becoming more and more common, but road stud manufacturers have found that the road stud body will also fail during long-term use. The main reason for the damage of the dog spike body may be the insufficient strength of the material used for the road stud body. In the actual use of it, due to the static pressure load and impact load, the static pressure load is mainly formed by the tire pressing on the road stud when the vehicle is stationary; and the impact load is mainly caused by the tire running over the road when the vehicle is running. generated when nailing. These conditions will cause the failure of the railroad spike.
