For easy checking and determination of versines in track track curves .

It can be used for all common rail profiles . Magnet type .

Curve versine measuring box, is also called string box for railway curve measurement. It is a necessary tool for railway works construction. Curve positive vector measuring box is a regular work in rail line maintenance. In order to facilitate the work of the worker to complete this job, a new line curve positive vector measuring box has been development.

Feature Curve versine measuring box is a fine production, it is portable, pocket, and good looking. The box body resistant ABS material for yellow, and easy to operate.

The protective device for the gauge gauge used in the railway work section includes the gauge gauge body and two cleaning components. The gauge head is fixed on both sides of the bottom end of the gauge gauge body, and the end away from the gauge gauge body is fixed with a protective sleeve. The inside of the protective sleeve rod is provided with a chute, and the two cleaning components include a first sliding rail, a first sliding plate, a second sleeve, a second sliding block, a push rod, a second connecting rod, a connecting column, two There are two second sliding rails and two second sliding plates, and the beneficial effect of the present invention is that the rubber blocks arranged at one end of the two second connecting rods and the sponge sleeves sleeved on the surfaces of the two rubber blocks can prevent the The oil stains on both sides of the gauge body are wiped off; the dampers arranged on both sides of the top of the chute can play a buffering role when the protective sleeve rod is collided, so that the gauge body inside the gauge body can be buffered. protection.
