[0002] In industrial production, there is a kind of detection that belongs to radian detection. In mathematics and physics, radian is the unit of angle measurement. It is a unit derived from the International System of Units. The unit abbreviation is rad. Definition: The arc length is equal to the radius of the arc, and the central angle it corresponds to is one radian, that is, two rays are emitted from the center of the circle to the circumference, forming an angle and an arc that is directly opposite to the angle. When the length of this arc is exactly equal to the radius of the circle, the radian of the angle between the two rays is one. The radian detection device is needed in the spraying process of wind power towers.

[0003] The existing patent CN216432815U proposes an arc measuring gauge, which relates to the technical field of arc measuring tools.

[0022] In order to make the purpose, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with the accompanying drawings and embodiments.

[0023] Example 1

[0024] In one embodiment, Figure 1-Figure 3 As shown, an adjustable detection block for auxiliary detection includes a fixed cross bar 12, two measuring rods 13 are symmetrically provided at the lower end of the fixed cross bar 12, and a fixed wheel 14 is rotatably provided at the lower end of each measuring rod 13. Two measuring mechanisms for measuring curvature are also symmetrically provided at the lower end of the fixed cross bar 12, which is convenient for measuring the curvature of an object. When two measuring mechanisms are set up, two sets of measurement data will be obtained during measurement. When the two sets of data values ​​are consistent, the curvature of the object being measured is a regular circle, thereby determining whether the measured curvature is a regular arc. A housing 11 that is easy to hold is provided at the upper end of the fixed cross bar 12. A squeezing mechanism for locking the measuring scale of the measuring mechanism is also provided on the fixed cross bar 12. After measuring the object being measured, the measuring scale can be locked by hydraulic pressure to facilitate reading the measurement value.

[0025] The measuring mechanism includes a sliding groove 24 fixed on the upper end of the fixed cross bar 12, a sliding plate 25 is slidably provided inside the sliding groove 24, a movable pressure rod 27 is provided at the lower end of the sliding plate 25, a movable wheel 28 is rotatably provided at the lower end of the movable pressure rod 27, the lower end of the sliding plate 25 is connected to the fixed cross bar 27 by a third spring 26, scale bars are distributed on the surface of the sliding groove 24, the sliding groove 24 is made of transparent material, and is used to measure the curvature of an object. Setting scale bars and using transparent materials can make the observation and measurement data more intuitive.

[0026] The extrusion mechanism includes a hydraulic cylinder 19 arranged at the lower end of the fixed cross bar 12, and extrusion connecting rods 21 are symmetrically arranged on both sides of the hydraulic cylinder 19. The extrusion connecting rods 21 are slidably arranged with the sliding holes on the hydraulic cylinder 19, and an extrusion block 20 corresponding to a movable pressure rod 27 is provided at the end of the extrusion connecting rod 21. A piston plate 18 is slidably provided inside the hydraulic cylinder 19, and the upper end of the piston plate 18 is connected to a pushing component for driving it to move up and down, and is used in conjunction with the extrusion mechanism arranged at its lower end to transmit thrust to the extrusion mechanism.

[0027] The pushing assembly includes a movable connecting rod 17, which is slidably set in a through hole in the middle position of the fixed cross bar 12. The upper end of the movable connecting rod 17 is connected and fixed to the lower end of the pull rod 16. The two ends of the pull rod 16 are slidably connected to the inner wall of the shell 11. The pull rod 16 and the shell 11 are connected and fixed by a first spring 15, which can push the extrusion mechanism and cooperate with the extrusion mechanism to extrude and fix the measuring scale.

[0028] Example 2

[0029] An elastic layer is distributed on the lower surface of the pull rod 16 to improve the comfort of pressing or pulling the pull rod 16 .

[0030] The inner wall of the housing 11 is provided with a vertical sliding groove matched with the end of the pull rod 16, so that the pull rod 16 can slide up and down inside the vertical sliding groove.

[0031] The surface of the extrusion block 20 is provided with an arc groove matched with the movable pressing rod 27, and the surface of the arc groove is provided with an anti-skid layer to prevent the measuring device from sliding in a certain process and affecting the reading of the measured value.

[0032] When it is necessary to measure the curvature of an object, the surface of the movable pressure rod 27 is pressed against the object to be measured. At this time, the fixed wheel 14 is squeezed by the curved surface of the object to be measured and moves upward. When it is completely pressed against the curved surface of the object to be measured, the pull rod 16 is pushed downward. While the pull rod 16 moves downward, it drives the movable connecting rod 17 to move downward. The piston plate 18 is squeezed by the thrust of the movable connecting rod 17 to squeeze the liquid inside the hydraulic cylinder 19. At this time, the moving block 23 moves toward the outside of the hydraulic cylinder 19. The movement of the moving block 23 drives the squeezing connecting rod 21 to squeeze the squeezing block 20. The squeezing block 20 can squeeze and fix the measuring rod 13, so as to lock the scale on the surface of the measuring rod 13 and obtain the curvature value.

[0033] The above is only a specific implementation of the present disclosure, but the protection scope of the present disclosure is not limited thereto. Any person skilled in the art who is familiar with the technical field can easily think of changes or substitutions within the technical scope disclosed in the present disclosure, which should be included in the protection scope of the present disclosure. Therefore, the protection scope of the present disclosure should be based on the protection scope of the claims.
