[0015] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0016] See also Figure 1-3 The utility model provides a technical solution: a device for measuring the bending radius of rail vehicle cables, comprising a square ruler 1, a bevel ruler 2 and a sliding ruler 3. A bevel ruler fixing card 4 is installed on the upper end of the rear wall of the square ruler 1, and a slot is provided on the bevel ruler fixing card 4. A strip slide groove is provided on the rear wall of the square ruler 1 and near the lower end. The upper end of the bevel ruler 2 is inserted into the slot, and a protrusion is provided at the lower end of the bevel ruler 2 and inserted into the strip slide groove. A rotating column 5 is inserted on the square ruler 1, and the sliding ruler 3 is placed on the rotating column 5.
[0017] As a preferred technical solution, further, the two right-angled sides of the square ruler 1 and the hypotenuse of the oblique ruler 2 are combined into a right triangle.
[0018] As a preferred technical solution, further, a circular through hole is provided on the sliding ruler 3 to facilitate installation on the right-angle ruler 1 through the rotating column 5 .
[0019] It should be noted that the utility model is composed of a right-angle ruler 1, an inclined ruler 2 and a sliding ruler 3.
[0020] The inclined ruler is combined by the inclined ruler fixing card on the right-angle ruler and the sliding groove opened at the bottom of the right-angle ruler 1, and the sliding ruler passes through the right-angle ruler 1.
[0021] The rotating columns are combined.
[0022] After the inclined ruler and the square ruler 1 are combined, the two right-angled sides of the square ruler 1 and the hypotenuse of the inclined ruler 2 form a right triangle. The outer diameter of the cable can be measured by sliding the inclined ruler and using the clamping teeth designed at the bottom of the square ruler 1 and the inclined ruler 2. At the same time, the hypotenuse of the inclined ruler 2 intersects with the long side of the square ruler 1, and the value of the intersection can be read. This value is the value of the cable bending radius. The sliding ruler 3 is used to lock the numerical length of the intersection of the ruler and the inclined ruler 2. In the case that the length value is inconvenient, the cable bending curve can be obtained by rotating the sliding ruler.
[0023] The angle formed by the short right-angled side of the triangle and the hypotenuse of the inclined ruler 2 is calculated according to trigonometric functions and cable radius requirements specified in different standards. Therefore, various types of measuring devices can be obtained by designing inclined rulers 2 with different angles.
[0024] It should be noted that: select a measuring device that matches the standard requirements of the cable bending radius.
[0025] Clamp the bottom clamping part of the device to the cable diameter, slide the inclined ruler to lock the outer diameter of the cable, and read the cable bending radius value according to the intersection of the ruler scale, support and inclined ruler 2.
[0026] Rotate the sliding ruler to the long side of square ruler 1, lock the values according to square ruler 1 and bevel ruler 2, slide the sliding ruler 3, and when the scale on the head of one side of the sliding ruler is consistent with the locked value scale of square ruler 1, lock the current position and size of the sliding ruler.
[0027] The measuring device is placed at the cable bend according to the cable assembly position and angle. By rotating the sliding ruler, a trajectory that conforms to the cable bending radius can be obtained. By comparing it with the actual cable assembly curve trajectory, it can be measured whether the cable bending radius at that location meets the requirements.
