Detailed Implementation

[0020] Through observation Figures 1 to 9 An exemplary working process for swing monitoring, as shown in the figure, is as follows:

[0021] A measuring and control instrument includes a side frame 11 with a central shaft 15 at its front end. A motor 13 is mounted on the left end of the side frame 11. A swing arm 14 is fixed to the output shaft of the motor 13. A connecting rod 08 is rotatably connected to the other end of the swing arm 14. The connecting rod 08 is rotatably connected to the left end of a rack 06. The rack 06 meshes with a gear 09, which is rotatably connected to the front end of the central shaft 15. A rotating arm 05 is rotatably connected to the outer wall of the central shaft 15. The rack 06 slides in the rotating arm 05. A mounting plate 01 is mounted on the rotating arm 05. Measuring instruments 03 are mounted on both the front and rear sides of the lower end of the mounting plate 01. During use, the rotation of the output shaft of the motor 13 drives the swing arm 14 to rotate, thereby causing the connecting rod 08 on the swing arm 14 to rotate. The lever 08 pulls the rack 06 to slide back and forth in the rotating arm 05, which enables the rack 06 to mesh with the gear 09 and rotate back and forth. During the rotation, the left end of the connecting rod 08 can be displaced in the vertical direction through the swing arm 14, thereby causing the left end of the rack 06 to move up and down. This causes the right end of the rack 06 to move up and down with the position of contact with the gear 09 as the fulcrum, thus achieving the tilting of the rack 06. When the rack 06 tilts, it can drive the rotating arm 05 to tilt, causing the mounting plate 01 on the rotating arm 05 to tilt and swing. This causes the measuring device 03 at the lower end of the mounting plate 01 to swing back and forth in the vertical direction to measure the target to be monitored from multiple angles.

[0022] Through observation Figures 1 to 9 An exemplary working process of the protective measuring device 03, as shown in the figure, is as follows:

[0023] A protective plate 12 is fixedly connected to the upper end of the side frame 11. The protective plate 12 is made of transparent plastic. The right end of the rack 06 and the outer end of the swing arm 14 are provided with sponge heads 07 that can contact the inner walls of the left and right sides of the protective plate 12. The protective plate 12 can protect the swinging structure and the measuring instrument 03 during use, and can avoid damage caused by external collisions. At the same time, when the swing arm 14 rotates, the sponge head 07 on the swing arm 14 can wipe the inner wall of the left side of the protective plate 12. Similarly, when the right end of the rack 06 swings and extends, the sponge head 07 on the right end of the rack 06 can wipe the inner wall of the right side of the protective plate 12, thereby preventing the inner wall of the protective plate 12 from being dirty and affecting the measurement effect of the measuring instrument 03.

[0024] Through observation Figures 1 to 9 An exemplary working process for tilting forward and backward, as shown in the figure, is as follows:

[0025] The mounting plate 01 is rotatably connected to the rotating arm 05 and can rotate in the front-to-back direction; during use, it can drive the mounting plate 01 to rotate and tilt in the front-to-back direction to change the position of the measuring device 03, so that the measuring device 03 can make a certain displacement relative to the mounting plate 01 when it is not tilted, and can move the measuring device 03 in time to continue to use when encountering obstacles.

[0026] Through observation Figures 1 to 9 An exemplary working process for adjusting the direction and angle, as shown in the figure, is as follows:

[0027] The side frame 11 is detachably connected to the rotating frame 22, the rotating frame 22 is rotatably connected to the rotating plate 23, the left end of the rotating plate 23 is rotatably connected to the base plate 24, the base plate 24 is provided with an arc track 25, and the front end of the rotating plate 23 is provided with a bolt and a nut that pass through the arc track 25; during use, by moving the bolt up and down in the arc track 25, the rotating plate 23 can be rotated and tilted on the base plate 24, thereby changing the tilt angle and direction of the side frame 11 in the left and right directions, and enabling multi-angle use;

[0028] Furthermore, the rotating frame 22 is driven to rotate by a geared motor installed at the bottom of the rotating plate 23. The geared motor drives the rotating frame 22 to rotate on the rotating plate 23, which can rotate in the horizontal direction. This allows the side frame 11 to drive the measuring device 03 for use at multiple angles and in multiple directions. The rotation of the rotating frame 22 and the tilting of the rotating plate 23 enable the measuring device 03 to be adjusted and used at multiple angles and in multiple directions at will.

[0029] Through observation Figures 1 to 9 An exemplary working process of forward and backward tilting and swinging can be obtained from the figure as follows:

[0030] The mounting plate 01 and gear 09 are respectively provided with a locking hole 04 and a locking groove 10 at their front ends. A cam 16 and a telescopic rod 19 are inserted into the locking hole 04 and locking groove 10, respectively. A sliding groove 21 is provided on the cam 16, and a sliding rod 17 slides in the sliding groove 21. A connecting ball 18 rotates at the upper end of the sliding rod 17 and is fixed to the front end of the telescopic rod 19. The left end of the sliding groove 21 gradually approaches the axis of rotation of the cam 16 and the right end gradually moves away from the axis of rotation of the cam 16. When the cam 16 rotates clockwise, the sliding rod 17 will move downward in the sliding groove 21, and when the cam 16 rotates counterclockwise, it will drive the sliding rod 17 to move upward. Before use, the cam 16 and the telescopic rod 19 can be adjusted by adjusting the sliding groove 19. When the telescopic rod 19 is inserted into the locking hole 04 and the locking groove 10, the sliding rod 17 can be raised and lowered by the sliding groove 21 when the gear 09 drives the cam 16 to rotate back and forth. When the connecting ball 18 at the upper end of the sliding rod 17 rotates and the telescopic rod 19 extends and retracts, the telescopic rod 19 drives the mounting plate 01 to rotate on the rotating arm 05. When the cam 16 rotates clockwise, the mounting plate 01 rotates forward, and when the cam 16 rotates counterclockwise, the mounting plate 01 rotates backward. This allows the measuring device 03 to tilt in the front and back direction when it swings up and down, and allows the measuring device 03 to move along a virtual arc for monitoring.

[0031] Through observation Figures 1 to 9 An exemplary workflow for transmitting information, as shown in the diagram, is as follows:

[0032] The cam 16 is fixedly connected to a sensor 20 at its front end, and a sensor 02 is fixedly connected to the upper end of the mounting plate 01. The sensor 20 and the sensor 02 can provide timely feedback on the monitored information and operating status.

[0033] Through observation Figures 1 to 9 An exemplary working process for avoiding deformation can be obtained from the figure as follows:

[0034] Both the swing arm 05 and the rack 06 are made of wear-resistant materials, which can prevent deformation of the swing arm 05 and the rack 06 due to frictional wear, thus avoiding affecting operation.

[0035] Through observation Figures 1 to 9 An exemplary working process for automatic reset can be obtained from the diagram as follows:

[0036] A torsion spring is provided at the rotational connection between the mounting plate 01 and the rotating arm 05. When there is no external force causing the mounting plate 01 to rotate and tilt, the torsion spring can keep the mounting plate 01 in the middle position of the rotating arm 05. After the external force is removed, the torsion spring can drive the mounting plate 01 to automatically reset.
