Abstract

The invention discloses a point switch retention force tester. The problem that the retention force of a core data control panel of an S700K point switch cannot be tested in the maintenance process issolved. The point switch retention force tester in the scheme comprises a bottom plate; a base is fixed to the outer wall of the top of the bottom plate through bolts; a supporting plate is fixed tothe outer wall of the top of the base through bolts; a nut protection plate is fixed to the outer wall of the top of the supporting plate through bolts; a main shaft is fixed to the outer wall of thetop of the supporting plate through bolts; one end of the main shaft is located in the nut protection plate; a pushing mechanism is arranged on the outer wall of one side of the nut protection plate;and a pressure sensor is slidably connected to the outer wall of one side of the main shaft in a clamped mode. Lead screw transmission serves as a main body, the control panel is pushed to move horizontally, the pressure sensor is connected between the lead screw transmission and the control panel in series to measure the retention force of the control panel, retention force data are accurately tested, and corresponding maintenance and adjustment on the retention force in the maintenance process are facilitated.

Description

technical field [0001] The invention relates to the technical field of switch machine maintenance, in particular to a switch machine holding force tester. Background technique [0002] The switch machine refers to the important signal infrastructure equipment used to reliably change the position of the turnout, change the opening direction of the turnout, lock the tip rail of the turnout, and reflect the position of the turnout. It can well ensure driving safety, improve transportation efficiency, and improve the safety of driving personnel The S700K switch machine is one of them, and a switch machine retention tester is required for its maintenance. [0003] At present, most of the existing switch machine retention testers on the market have the following deficiencies in the process of use: they cannot solve the problem of testing the core data control panel retention of the S700K switch machine maintenance, In summary, most of the existing switch machine holding force tes...
