Turnout close-fitting inspection rod device and turnout close-fitting inspector

Abstract

The invention discloses a turnout close-fitting inspection rod device. The turnout close-fitting inspection rod device comprises an inspection rod, and a close-fitting position detection unit and a repulsion position detection unit which are arranged on the inspection rod; the inspection rod comprises a square rod and a circular rod; a groove is formed in the upper surface of the square rod; the close-fitting position detection unit and the repulsion position detection unit are arranged in the groove along the axial direction of the square rod; the close-fitting position detection unit comprises a first quick-acting piece, the repulsion position detection unit comprises a repelling adjusting base and a second quick-acting piece, the repelling adjusting base is movably fixed to the bottom of the groove, and the side portion of the repelling adjusting base is further provided with a repelling inclined face and a repelling plane which extend to the upper surface of the side wall of the groove. And a displacement sensor information strip is arranged on the outer side wall of the inspection rod. The invention further discloses a turnout close-fitting inspector. The turnout close-fittinginspection rod device and the turnout close-fitting inspector can realize turnout stroke adjustment of the position, away from the point rail, of the check point within the range of 60 mm-175 mm, full stroke monitoring of the position of the check point of the turnout is achieved, good dustproof and waterproof sealing is achieved, and the protection level can reach IP66 or above.

Description

technical field [0001] The invention relates to the field of close-fit checkers for turnouts, in particular to a close-fit check rod device for turnouts and a close-fit checker for turnouts. Background technique [0002] The check rod of the turnout close-fit checker is also called the indicator rod, which is mostly square. It is used in the close-fit checker of the turnout, and the wear and tear with the guide is large, and the waterproof effect is not ideal. The most important thing is that the switch point rail is in the repelling position The actual state at the time cannot be effectively checked, and it does not have the function of stroke supervision. [0003] Under normal circumstances, the check rod of the existing turnout close-fitting checker moves more than 65mm from the close-fitting position to the repelling position on the switch tip rail, and in the process of reaching the repelling position, the repelling indicates that the contact is always connected, which ...

[0002] The check rod of the turnout close-fit checker is also called the indicator rod, which is mostly square. It is used in the close-fit checker of the turnout, and the wear and tear with the guide is large, and the waterproof effect is not ideal. The most important thing is that the switch point rail is in the repelling position The actual state at the time cannot be effectively checked, and it does not have the function of stroke supervision

[0003] Under normal circumstances, the check rod of the existing turnout close-fitting checker moves more than 65mm from the close-fitting position to the repelling position on the switch tip rail, and in the process of reaching the repelling position, the repelling indicates that the contact is always connected, which cannot be specified. Reflect the actual travel of the turnout at the checkpoint

In addition, when the switch point rail moves from the repelling position to the close position and exceeds the actual stroke deviation value, the repelling point cannot be cut off. Only when the opening stroke is less than 65mm can the repelling point be cut off. The status when repelled from the position cannot be reflected correctly, so there are certain defects
