The invention relates to an electric limiting wrench for installing an e-shaped elastic strip. The elastic limiting wrench is used for installing the e-shaped elastic strip at two sides of a steel rail, and comprises a main body frame, an elastic strip pull-in mechanism and a control system, the elastic strip pull-in mechanism comprises a double-output-shaft motor, a bidirectional electric pull rod and an elastic strip wrench, the double-output-shaft motor is connected with the bidirectional electric pull rod, the bidirectional electric pull rod is connected with the elastic strip wrench, the double-output-shaft motor provides pulling force for the elastic strip wrench through the bidirectional electric pull rod so that the elastic strip wrench can be controlled to install the e-shaped elastic strips to the two sides of a steel rail, and the control system is used for controlling starting and stopping of the double-output-shaft motor and monitoring the installation process and the installation state of the e-shaped elastic strips. The elastic strip pull-in mechanism and the control system are both arranged on the main body frame, and the main body frame is used for fixing the positions of the elastic strip pulling-in mechanism and the control system on a steel rail or moving the elastic strip pulling-in mechanism and the control system on the steel rail. The installation efficiency of the elastic strip can be improved, the installation process and state of the e-shaped elastic strip can be monitored, and standard installation is guaranteed.
Description
technical field [0001] The invention relates to a railway fastener system, in particular to an electric limit wrench for installing an e-shaped spring bar. Background technique [0002] In the track structure of the railway and urban rail system, the rail is fixed on the sleeper and the substructure through different forms of fasteners and fastener clips. The rail provides limited movement space, prevents excessive movement of the rail relative to the sleeper, and maintains the stability of the track structure. [0003] At present, in the domestic subway fasteners, most of the fasteners used in a large number are e-type elastic strips, and the installation method is a bolt-free installation structure, combined with a pre-embedded iron seat and iron backing structure. The structural feature is that the parts are relatively Less, but in the subway track fastener system, especially in small radius curves and in and out of the station, the clips are prone to breakage, requiring...
