[0024] The present invention will now be further described in detail in conjunction with the accompanying drawings and preferred embodiments. These drawings are simplified schematic diagrams that only illustrate the basic structure of the present invention in a schematic manner, and therefore only show the components related to the present invention.

[0025] Reference Figure 1 , Figure 2 and Figure 3 As shown, the utility model provides a technical solution: an unmanned excavator rotation angle measuring device, including a mounting frame 1, a groove 2 is opened at the rear end of the mounting frame 1, a clamping plate 3 is slidably connected inside the groove 2, the number of the clamping plates 3 is two and both are slidably connected to the inside of the groove 2, a mounting block 4 is fixedly connected to the front end of the mounting frame 1, an adjusting arm 5 is fixedly connected to the bottom of the mounting block 4, a telescopic arm 6 is slidably connected inside the adjusting arm 5, an angle measuring device 7 is fixedly connected to the bottom of the telescopic arm 6, an adjusting box 8 is fixedly connected to the front end of the adjusting arm 5, a slide plate 9 is slidably connected inside the adjusting box 8, and a fixed plate 9 at the front end of the slide plate 9 A pull rod 10 is connected, a pull block 11 is fixedly connected to the front end of the pull rod 10, an insertion rod 12 is fixedly connected to the rear end of the slide plate 9, and a socket 13 is opened at the front end of the telescopic arm 6. The staff pulls the pull block 11 to drive the pull rod 10, and the pull rod 10 pulls the slide plate 9 to drive the insertion rod 12, so that the insertion rod 12 is released from the limit between the socket 13, and the limit of the telescopic arm 6 is released at the same time. The staff moves the telescopic arm 6 at both ends, aligns the insertion rod 12 with the socket 13 after adjusting to the applicable angle and inserts it, and fixes the position of the telescopic arm 6, so that the staff can extend the angle of the angle measuring device 7 to better calibrate the measurement angle.

[0026] Reference Figure 3As shown, in this implementation scheme: both sides of the front end of the slide plate 9 are fixedly connected with a storage spring 14, and the front end of the storage spring 14 is fixedly connected to the front end of the inner part of the adjusting box 8. The staff pulls the pull rod 10 to drive the slide plate 9. The slide plate 9 squeezes the storage spring 14 to compress and store force during the forward movement, and at the same time releases the limit between the insertion rod 12 and the socket 13. The staff aligns the insertion rod 12 with the socket 13 and releases the pull block 11. Under the action of the rebound force of the storage spring 14, the insertion rod 12 is quickly inserted into the socket 13 for fixation.

[0027] Reference Figure 4 As shown, in the present embodiment: slide grooves 15 are provided on both sides of the inside of the regulating box 8, and sliders 16 are fixedly connected on both sides of the slide plate 9. The surface of the slider 16 is slidably connected to the inside of the slide groove 15. When the staff moves the slide plate 9, the slider 16 is driven to slide inside the slide groove 15. The setting between the slide groove 15 and the slider 16 fixes the moving trajectory of the slide plate 9, and avoids jamming caused by shaking when the slide plate 9 moves in the inner cavity of the regulating box 8.

[0028] Reference Figure 4 As shown, in this embodiment: sliding grooves 17 are opened on both sides of the adjusting arm 5, and sliding blocks 18 are fixedly connected on both sides of the telescopic arm 6. The surface of the sliding block 18 is slidably connected to the inside of the sliding groove 17. When the staff moves the telescopic arm 6, the sliding groove 17 is driven to move inside the sliding block 18. Through the setting between the sliding groove 17 and the sliding block 18, the moving trajectory of the telescopic arm 6 is fixed, and at the same time, the telescopic arm 6 is prevented from falling off and being damaged when extending downward.

[0029] Reference Figure 3 As shown, in this embodiment: the outer diameter of the rod 12 is matched with the inner diameter of the hole 13, the number of holes 13 is several and they are all distributed at the front end of the telescopic arm 6, and the setting that the outer diameter of the rod 12 is matched with the inner diameter of the hole 13 allows the staff to insert the rod 12 into the hole 13 firmly, so as to avoid the sliding of the telescopic arm 6 and cause the measurement angle to have an error deviation.

[0030] Reference Figure 5 and Figure 6 As shown, in this embodiment: a spring groove 19 is opened inside the clamp 3, a reset spring 20 is fixedly connected to the top of the spring groove 19, an insert block 21 is fixedly connected to the top of the reset spring 20, and a slot 22 is opened on the surface of the mounting frame 1. The staff presses down the insert block 21 to push the insert block 21 into the groove 2, and the insert block 21 releases the limit between the slot 22. The staff moves the clamp 3 to clamp and install the measuring body, and fixes it to the surface of the measuring body, so that the staff can quickly install and disassemble it.

[0031] Reference Figure 6As shown, in this embodiment: limiting grooves 23 are provided on both sides of the spring groove 19, limiting blocks 24 are fixedly connected on both sides of the plug block 21, and the surface of the limiting block 24 is slidably connected to the inside of the limiting groove 23. When the staff presses or makes the plug block 21 rebound upward, the limiting groove 23 and the limiting block 24 are set, and when the plug block 21 moves, the limiting block 24 is driven to slide inside the buffer spring 25, thereby stabilizing the moving trajectory of the plug block 21 and preventing the plug block 21 from rebounding excessively under the action of the rebound force of the spring groove 19.

[0032] Reference Figure 6 As shown, in this embodiment: buffer springs 25 are fixedly connected to both sides of the groove 2, and a buffer plate 26 is fixedly connected to the left end of the buffer spring 25. In order to avoid damage caused by collision between the splint 3 and the inner wall of the mounting frame 1 during movement, the buffer spring 25 and the buffer plate 26 are arranged so that when the splint 3 collides with the buffer plate 26, the buffer spring 25 performs buffering protection.

[0033] Reference Figure 5 and Figure 6 As shown, in this implementation scheme: the size of the plug block 21 is compatible with the size of the slot 22, the number of slots 22 is several and all are opened at the top of the mounting frame 1, and the size of the plug block 21 is configured to be compatible with the size of the slot 22. When the spring groove 19 accumulates force to rebound the plug block 21, the plug block 21 pops out and limits itself with the slot 22, avoiding shaking caused by excessive gaps, and at the same time avoiding the inability of the plug block 21 to rebound due to excessive gaps.

[0034] Reference Figure 1 As shown, in this embodiment: the material of the splint 3 is polyphenylene sulfide plastic. By setting the splint 3 as polyphenylene sulfide plastic, the splint 3 has the advantages of high mechanical strength, high temperature resistance, chemical resistance, flame retardancy, good thermal stability, excellent electrical properties, etc.

[0035] The practical working principle of the present invention is as follows: the staff pulls the pull block 11 to drive the pull rod 10, and the pull rod 10 pulls the slide plate 9 to drive the plug rod 12, so that the plug rod 12 is released from the limit between the plug hole 13, and the limit of the telescopic arm 6 is released at the same time. The staff moves the telescopic arm 6 at both ends, and after adjusting to the applicable angle, the plug rod 12 is aligned with the plug hole 13 and inserted, and the position of the telescopic arm 6 is fixed, so that the staff can extend the angle of the angle measuring device 7 to better calibrate the measurement angle. The staff pulls the pull rod 10 to drive the slide plate 9, and the slide plate 9 squeezes the storage spring 14 to compress and store force during the forward movement, and at the same time releases the limit between the plug rod 12 and the plug hole 13, and the staff aligns the plug rod 12 with the plug hole 13 and releases it. Pull block 11, under the action of the rebound force of the storage spring 14, quickly insert the insertion rod 12 into the socket 13 for fixing. In the process of moving the slide plate 9, the staff drives the slider 16 to slide inside the slide groove 15. The setting between the slide groove 15 and the slider 16 fixes the movement trajectory of the slide plate 9, and avoids the jamming caused by shaking when the slide plate 9 moves in the inner cavity of the adjustment box 8. In the process of moving the telescopic arm 6, the staff drives the sliding groove 17 to move inside the sliding block 18. The setting between the sliding groove 17 and the sliding block 18 fixes the movement trajectory of the telescopic arm 6, and avoids the telescopic arm 6 from falling off and being damaged when it extends downward. The outer diameter of the insertion rod 12 is adapted to the inner diameter of the socket 13. When the staff inserts the insertion rod 12 into the socket 13, it is inserted firmly to prevent the telescopic arm 6 from sliding and causing an error in the measurement angle. The staff presses the insertion block 21 downward to push the insertion block 21 into the groove 2. The insertion block 21 releases the limit between the insertion block and the slot 22. The staff moves the clamp 3 to clamp and install the measuring body, and fixes it to the surface of the measuring body so that the staff can quickly install and disassemble it. When the staff presses or makes the insertion block 21 rebound upward, the limit groove 23 and the limit block 24 are set, and when the insertion block 21 moves, the limit block 24 is driven to slide inside the buffer spring 25, so as to stabilize the movement trajectory of the insertion block 21 and prevent the insertion block 21 from being too far under the action of the rebound force of the spring groove 19. In order to prevent the clamping plate 3 from colliding with the inner wall of the mounting frame 1 and causing damage during the movement, the staff uses the buffer spring 25 and the buffer plate 26 to provide buffer protection when the clamping plate 3 collides with the buffer plate 26. The size of the plug block 21 is matched with the size of the slot 22. When the spring slot 19 stores force to rebound the plug block 21, the plug block 21 pops out and limits itself with the slot 22 to prevent shaking caused by excessive gaps and the inability of the plug block 21 to rebound due to excessive gaps. The material of the clamping plate 3 is polyphenylene sulfide plastic, so that the clamping plate 3 has the advantages of high mechanical strength, high temperature resistance, chemical resistance, flame retardancy, good thermal stability, and excellent electrical properties.
