Description

Technical Field

[0001] The utility model relates to the technical field of bolt shot blasting tooling, in particular to a switch sleeper bolt shot blasting tooling. Background Art

[0002] Switch sleepers are special sleepers used on railway turnouts, mainly used at turnout traction points. The turnout electrical conversion rods can be placed inside the sleepers, which is beneficial for large machine maintenance operations. Switch sleepers are installed and fixed by bolts. Since domestic track specifications are unified, the specifications of switch sleepers and the bolts used are also relatively unified.

[0003] After searching, it was found that the publication number is CN217225120U, and the name is a universal bolt shot blasting and rust removal tool. The application proposes that the existing universal bolt shot blasting and rust removal tool needs to be replaced with a tool of corresponding size before rust removal of bolts of different batches and specifications. The replacement is troublesome, and the width of all bolt installation positions on the tool cannot be adjusted at the same time to accommodate bolts of different specifications. The replacement speed is slow, the work efficiency is low, and the number of bolts placed at the same time is small, and the energy utilization rate is poor. A universal bolt shot blasting tool is designed, but when installing the bolts, it will cause surface obstruction to the bolts to varying degrees, resulting in incomplete shot blasting and affecting the shot blasting efficiency. Further improvements can be made.

[0004] Currently, no effective solution has been proposed for the problems in the related technologies. Utility Model Content
