Description

Detection tester for drawing force of railway spike Technical Field The utility model belongs to the technical field of railway track testing, and particularly relates to a railway spike drawing force detection tester. Background The main function of the railway spike drawing force detection is to ensure the safe operation of the high-speed train. The high-speed railway has higher running speed and higher load on the track, so that the ballastless track and the fastener have higher requirements, the fastener system tightly connects the steel rail with the sleeper at the bottom to provide sufficient longitudinal, transverse and vertical resistance to ensure the high-speed railway running on the steel rail, and the detection principle is that the vertical load is applied to the fastener embedded part embedded in the concrete in advance, and the pulling resistance of the embedded part is determined through the load holding capacity in the test process and the state of the joint of the embedded part and the concrete after the test. The method comprises the specific steps of applying vertical load to the embedded part, wherein the load direction is consistent with the axis of the embedded part, the loading speed is generally 40-60 kN/min, the embedded part is kept for 3 minutes after being loaded to a design value, then the embedded part is slowly unloaded, and the state of the embedded part and the joint of the embedded part and the sleeper after being unloaded is recorded. However, the traditional detection tester has the following defects that the traditional tester is connected with the railway spike by pouring the sulfur anchoring agent, the screw spike is directly inserted into the screw spike, and after the anchoring agent is completely solidified, the assembly and anchoring of the railway spike can be completed, so that the whole operation is very complicated, and the detection efficiency of the tester is reduced.
