Description

Technical Field

[0001] The utility model relates to the technical field of urban transportation, in particular to a contact rail emergency repair steel base. Background Art

[0002] Running rails refer to the tracks on which trains run. The main function of the running rails is to support the weight of the trains and guide them along the predetermined routes. There are also contact rails on the outside of the running rails. The contact rails are the core components of subway train traction and current collection, and play an important role in the safe operation of the subway. During the installation of the contact rails, the insulating brackets, as the load-bearing components of the contact rails, are fixed on the traditional steel base. Figure 1 As shown, the traditional steel base is installed by drilling and installing it on the integral ballast or sleeper using chemical anchor bolts or rear-enlarged bottom anchor bolts. Before installation, holes must be drilled on the ballast or sleeper for assembly. During the operation period of the subway, if the contact rail steel base anchor bolts are damaged and need emergency repair, the current solution is to re-clear or drill holes on the original integral ballast or sleeper, and use chemical anchor bolts or rear-enlarged bottom anchor bolts for assembly, which is time-consuming and labor-intensive. In the organization of urban rail transit operation, when a fault occurs and affects the operation, the construction work should be arranged according to the principle of "first open and then restore", that is, measures should be taken to ensure the smooth flow of the line so that the train can operate normally, and then the fault repair and restoration of facilities and equipment should be carried out.

[0003] Therefore, when the contact rail steel base anchor bolts are damaged and need emergency repair, the current repair plan is time-consuming and labor-intensive, and the feasibility of the emergency repair "first open and then restore" is not high. Utility Model Content
