Description

Technical Field

[0001] The utility model relates to the field of measuring reels, in particular to a portable RTK auxiliary measuring reel for channel measurement. Background Art

[0002] RTK technology has developed rapidly in recent years. It is widely used in various control measurements, topographic mapping, engineering route selection and engineering layout. Compared with conventional instruments, it has significantly improved work efficiency and accuracy. Traditional line survey work is very hard and tedious, and there are many problems such as long survey cycle and low work efficiency.

[0003] However, in daily surveying and mapping work, we often encounter locations that workers cannot reach, but other technical means cannot achieve and meet the surveying and mapping requirements. Manual measurement is very dangerous and cannot effectively guarantee the safety of workers and instruments. In areas that workers cannot reach, effective measurements cannot be carried out and estimates are often made, resulting in large data differences.

[0004] Therefore, for areas that the above-mentioned staff cannot reach, estimated values ​​are often used, resulting in large data differences. In this case, a portable RTK auxiliary measuring wheel for channel measurement can be designed. Through rotation adjustment and suction cup structure, the position of the measuring instrument in the channel can be flexibly adjusted while firmly fixing the measuring instrument. In this way, the areas that are difficult for staff to reach can be accurately measured, thereby enhancing the accuracy and reliability of the data. Utility Model Content

[0005] In order to overcome areas that staff cannot reach, estimated values ​​are often used, resulting in large data discrepancies.

[0006] The technical solution of the utility model is: a portable RTK auxiliary measuring reel for channel measurement, comprising a channel, a gantry, a measuring winding wheel, a measuring line, a fixing buckle, a fixing bolt, a fixing nut and a measuring line fixing ring; a gantry is installed at the upper end of the channel, a groove is provided at the front end of the gantry, measuring winding wheels are installed on the left and right sides of the groove, a measuring line is wound in the measuring winding wheel, there are two fixing buckles and a semicircular structure, front and rear ends of the two fixing buckles are integrally fixedly connected with fixing bolts, the two fixing buckles are connected together by fixing nuts, the left and right ends of the fixing buckles are fixedly connected with measuring line fixing rings, and the measuring line is connected to the measuring line fixing rings.

[0007] Preferably, the gantry serves as a supporting structure for the measuring line wheel and other measuring components, and the groove opened at the front end of the gantry is used to install the measuring winding wheel, which is used to wind and release the measuring line. By rotating the measuring winding wheel, the length of the measuring line can be controlled. The fixing buckles are connected together by fixing bolts and fixing nuts to form a complete circular structure, which firmly clamps the fixed rod in the middle. The measuring line fixing ring is used to connect the measuring line with the fixing buckle to ensure that the measuring line can smoothly drive the fixed rod to move during the measurement process.

[0008] Preferably, a fixing rod is provided in the fixing buckle, and a conical fixing head is fixedly connected to the lower end of the fixing rod. The fixing rod provides a stable support structure, and the fixing head at the lower end of the fixing rod helps the fixing rod to be better inserted into the silt in the channel, thereby firmly fixing the fixing rod in the channel.

[0009] Preferably, the upper end of the fixing rod is fixedly connected to the limit frame, and a threaded hole is provided through the outer wall of the limit frame. The outer thread of the adjusting screw is adapted to the threaded hole and the adjusting screw is threadedly connected to the threaded hole. A measuring instrument can be installed in the limit frame to measure the channel. At the same time, the limit frame also provides a stable support platform for the adjusting screw. The adjusting screw cooperates with the threaded hole in the limit frame, so that the staff can adjust the position of the splint by rotating the adjusting screw.

[0010] Preferably, the end of the adjusting screw located on the outside of the limit frame is integrally fixedly connected to a knob, and the end of the adjusting screw located on the inside of the limit frame is fixedly connected to a splint, and a suction cup is provided on the surface of the splint. The knob facilitates the staff to operate the adjusting screw, thereby adjusting the splint. The splint is used to clamp the measuring instrument, and the suction cup can increase the friction between the splint and the measuring instrument, thereby improving the stability of the clamping and ensuring that the measuring instrument can be firmly fixed in the limit frame.

[0011] Preferably, two rotating support seats are symmetrically installed on the inner wall of the rear end of the groove, and a connecting shaft is rotatably connected in each of the two rotating support seats. The rotating support seats are used to support and allow the connecting shaft to rotate. There is a bearing mechanism in the rotating support seat to reduce friction and provide smooth rotation. The connecting shaft can rotate freely in the support seat, thereby driving the measuring wheel to rotate.

[0012] Preferably, the front ends of the two connecting shafts are fixedly connected to discs, and the front ends of the discs are fixedly connected to handles. The discs rotate as the connecting shafts rotate. The staff can drive the discs to rotate by turning the handles, and the rotation of the discs in turn drives the connecting shafts to rotate.

[0013] Preferably, the portal frame consists of two columns and a crossbeam, and the front and rear ends of each column are fixedly connected to support plates by fastening bolts. The columns are the main vertical supporting components of the portal frame. They support the crossbeam and provide stability for the entire portal frame. The support plates at the front and rear ends of each column are used to provide additional support area, thereby ensuring the stability of the portal frame on the channel.

[0014] Beneficial effects of the utility model:

[0015] 1. By rotating the handle, the extension length of the measuring line can be flexibly adjusted, thereby achieving precise adjustment of the measuring instrument's position within the channel. This mechanism enables the measuring instrument to accurately measure areas that are difficult for workers to directly reach, thereby not only enhancing the accuracy and reliability of the data, but also greatly ensuring the safety of workers and effectively improving work efficiency;

[0016] 2. The suction cup uses its adsorption force to adsorb the splint and the measuring instrument together, so that the measuring instrument is fixed in the limit frame to prevent the fixing rod from shaking when it is lowered. BRIEF DESCRIPTION OF THE DRAWINGS

The gantry 2 serves as a supporting structure for the measuring line wheel and other measuring components. The groove opened at the front end of the gantry 2 is used to install the measuring winding wheel 3, and the measuring winding wheel 3 is used to wind and release the measuring line 4. By rotating the measuring winding wheel 3, the length of the measuring line 4 can be controlled. The fixing buckle 5 is connected together by the fixing bolt 6 and the fixing nut 7 to form a complete circular structure, which firmly clamps the fixing rod 9 in the middle. The measuring line 4 fixing ring is used to connect the measuring line 4 with the fixing buckle 5 to ensure that the measuring line 4 can smoothly drive the fixing rod 9 to move during the measurement process.

[0026] See also Figure 4-Figure 5In this embodiment, two rotating support seats 15 are symmetrically installed on the inner wall of the rear end of the groove. A connecting shaft 16 is rotatably connected in the two rotating support seats 15. The front ends of the two connecting shafts 16 are fixedly connected to a disc 17. The front end of the disc 17 is fixedly connected to a handle 18. The door frame 2 is composed of two columns and a crossbeam. The front and rear ends of each column are fixedly connected to a support plate 19 by fastening bolts. The rotating support seat 15 is used to support and allow the connecting shaft 16 to rotate. There is a bearing mechanism in the rotating support seat 15 to reduce friction. The connecting shaft 16 can rotate freely in the support seat, thereby driving the measuring wheel 3 to rotate, and the disc 17 rotates with the rotation of the connecting shaft 16. The staff can drive the disc 17 to rotate by turning the handle 18, and the rotation of the disc 17 in turn drives the connecting shaft 16 to rotate. The columns are the main vertical support components of the gantry 2. They support the beams and provide stability for the entire gantry 2. The support plates 19 at the front and rear ends of each column are used to provide additional support area, thereby ensuring the stability of the gantry 2 on the channel 1.

[0027] See also Figure 6 In this embodiment, a fixing rod 9 is provided in the fixing buckle 5, and the lower end of the fixing rod 9 is fixedly connected to a conical fixing head, and the upper end of the fixing rod 9 is fixedly connected to a limit frame 10. A threaded hole is opened through the outer wall of the limit frame 10, and the external thread of the adjusting screw 11 is adapted to the threaded hole and the adjusting screw 11 is threadedly connected to the threaded hole. The end of the adjusting screw 11 located on the outside of the limit frame 10 is integrally fixedly connected with a knob 12, and the end of the adjusting screw 11 located on the inside of the limit frame 10 is fixedly connected with a splint 13, and a suction cup 14 is provided on the surface of the splint 13. The fixing rod 9 provides a stable Support structure, the fixed head at the lower end of the fixing rod 9 helps the fixing rod 9 to be better inserted into the silt in the channel 1, so that the fixing rod 9 is firmly fixed in the channel 1, and the disc 17 rotates with the rotation of the connecting shaft 16. The staff can drive the disc 17 to rotate by turning the handle 18, and the rotation of the disc 17 in turn drives the connecting shaft 16 to rotate. The columns are the main vertical support components of the gantry 2. They support the beams and provide stability for the entire gantry 2. The support plates 19 at the front and rear ends of each column are used to provide additional support area, thereby ensuring the stability of the gantry 2 on the channel 1.

[0028] During the operation, the staff first securely places the gantry 2 on the upper edge of the channel 1. Then, they connect the measuring line 4 on the measuring wheel 3 with the measuring fixing ring on the fixing buckle 5. They then use the fixing bolt 6 and the fixing nut 7 to tightly fit the two fixing buckles 5 to form a stable circular structure, while ensuring that the fixing rod 9 is firmly clamped in it.

[0029] Next, the measuring instrument is safely placed in the limit frame 10, and by rotating the knob 12, the adjusting screw 11 is slowly moved with the help of the precise fit between the threads. This action will drive the clamping plate 13 and the suction cup 14 to slowly approach the measuring instrument, ultimately achieving a stable and precise fixation.

[0030] Once the measuring instrument is fixed, turning the handle 18 will drive the disc 17 to rotate, which in turn drives the connecting shaft 16 to rotate together, and finally causes the measuring wheel 3 to start rotating and release the measuring line 4. By releasing the length of the measuring line 4, the staff can flexibly adjust the position of the measuring instrument in the channel 1 to accurately measure areas that are difficult to reach with traditional methods.

[0031] Through the above steps, by rotating the handle 18, the extension length of the measuring line 4 can be flexibly adjusted, thereby achieving precise adjustment of the position of the measuring instrument inside the channel 1. This mechanism enables the measuring instrument to accurately measure areas that are difficult for workers to directly reach, thereby not only enhancing the accuracy and reliability of the data, but also greatly ensuring the safety of the workers, effectively improving work efficiency, and solving the problem that workers often have to make estimated values ​​in areas that they cannot reach, resulting in large data differences.

[0032] The embodiments of the present invention are described in detail above with reference to the accompanying drawings. However, the present invention is not limited to the above embodiments. Various changes can be made within the scope of knowledge possessed by those skilled in the art without departing from the purpose of the present invention.
