Abstract

A railway turnout closed switch inspector comprises a shell lid covering a base and constituting an outer shell. The inside of the shell lid is also provided with an inner cover constituting an inner shell. The bottom end of the base is provided with a lead pipe that is connected with the outside, the middle of the base is cut with an axle hole and the central upper end of the base is sequentially provided with a main shaft, a distributing connecting plate and a connection point part from down to top. The external periphery consisting of the connection point is correspondingly provided with an adjustable startup suite and a startup suite. The base is also fixedly provided with an internal tooth and an external tooth respectively connected with an adjustable startup suite tooth up and down, wherein the axial part of the main shaft penetrates through the axle hole of the base and the tip of the axial part extends outside the base and is fixedly connected with a link rod. The distributing connecting plate is fixedly connected with the base by a bolt penetrating through the main shaft, and the connection point part, the adjustable startup suite, the startup suite, the inner tooth and the outer tooth all rotate with the rotation of the main shaft. The inspector is convenient for adjustment and reliable in locking, not only amplifies action and needs no transmission mechanism for amplification, but also has compact structure and enhances the stability of action.

Description

technical field [0001] The invention relates to a close-bonding checker. In particular, it relates to a close-fit checker for railway turnouts, which is designed with two sets of joints on one checker to check the close-fit position and repulsion position of a switch rail. Background technique [0002] The tightness checker is used to check whether the point rail of the railway switch is close or separated. With the continuous increase of the speed of the railway train, the requirements for the position of the point rail of the turnout are getting higher and higher, and the position of the close point rail is particularly important. . [0003] At present, two close-fit checkers are installed on both sides of the switch for the close-fit inspection of the railway switch point rail. Each close-fit checker only checks the position of one point rail. Although this kind of close-fit checker uses arc contacts , In order to meet the requirements of the turnout system, because the...
