Description

Car coupler supporting seat clamping stagnation detector Technical Field The utility model relates to the technical field of inspection instruments, in particular to a car coupler supporting seat clamping stagnation inspection instrument. Background The car coupler supporting seat clamping stagnation is one of faults possibly occurring in the running process of the railway vehicle, and the checking process of the car coupler supporting seat clamping stagnation needs to be careful and comprehensive so as to ensure the driving safety; The checking mode is generally a jack checking method, namely, before the coupler is assembled, a jack is arranged between the upper plane of the supporting seat and the impact seat, the supporting seat is pressed down by operating the jack, the downward moving distance of the supporting seat is not less than 30mm, and the supporting seat is restored to the original position after the jack is withdrawn; The other mode is to use a crow bar with the length of about 2m after the coupler is assembled, insert one end of the crow bar into a gap between the coupler body and the impact seat along the longitudinal direction of the car body, press the other end of the crow bar manually, press the upper part of the coupler head by the crow bar to enable the coupler head and the support seat to move downwards, the downward moving distance of the support seat should not be less than 10mm, and the support seat should be restored to the original position after the crow bar is withdrawn. Disclosure of utility model The utility model aims to solve the technical problems that the existing inspection mode is generally composed of a jack method and a hook head needs to be disassembled, the workload is large, the crow bar is used for pressing the hook head in the manual method, two persons are needed to cooperate, the downward moving distance is inspected to confirm clamping stagnation, and the labor is consumed. In order to solve the problems, the technical scheme adopted by the utility model is that the car coupler supporting seat clamping stagnation detector comprises a shell, an extending structure is arranged at one end of the shell, a notch is formed in the lower side in the shell, an adjustable fixing structure is arranged in the notch, the adjustable fixing structure comprises a connecting shaft fixed on the inner side of the notch, a connecting block is rotatably arranged on the outer side of the connecting shaft, a limiting groove is formed in the lower side of the connecting block, a strong magnet is connected in the limiting groove, an anti-slip pad is arranged at one end of the connecting shaft, a threaded hole is formed in one side of the shell, a threaded fastening rod is rotatably connected with threads in the threaded hole, one end of the threaded fastening rod is abutted against one side of the connecting block, a distance detection port is arranged on the lower side of the extending structure, an indicator lamp is inlaid at one end of the shell, a charging port is formed in one end of the shell, a key is arranged on the upper side of the shell, and a proximity switch is arranged on one side of the shell.
