A scraping plate is sleeved outside the plug rod, and a spring is connected between the scraping plate and the supporting plate.

[0004] The above device can scrape off the soil adhered to the plug rod. However, when the device is in use, the main measuring instrument is fixed on the mounting base. After determining the measuring point, it is difficult to perform corresponding height adjustment to obtain a better measuring height. And when the measuring work is not carried out, the measuring instrument has no protection measures and is easily affected by external factors, resulting in a decrease in the measurement accuracy. Content of the Utility Model

[0005] The main purpose of the utility model is to provide a mine topographic surveying device which is convenient to erect, which can effectively solve the technical problem that it is difficult to perform corresponding height adjustment after determining the measuring point in the background technique.

[0006] To achieve the above purpose, the technical solution adopted by the utility model is as follows:

[0007] A mine topographic surveying device which is convenient to erect includes a placing plate. A supporting plate is fixedly installed on the top of the placing plate. Two connecting blocks are fixedly installed on the top of the supporting plate. A connecting rod is rotatably connected to the outer walls of the two connecting blocks. A fastening bolt is threadedly connected to the outer walls of the two connecting blocks. A fixing plate is fixedly installed on the top of the supporting plate. A sliding column is arranged on the top of the supporting plate and the outer wall of the sliding column penetrates through the outer wall of the fixing plate and a measuring instrument is fixedly installed. Two first rotating blocks are fixedly installed on the outer wall of the sliding column, and one end of the connecting rod is rotatably connected to the outer wall of the first rotating block.

[0008] As a further solution of the utility model, protective cases are rotatably connected to the outer walls on both the left and right sides of the fixed plate. A second rotating block is fixedly installed on the outer wall of the protective case, and the other end of the connecting rod is threadedly connected to the outer wall of the second rotating block.

[0009] As a further solution of the utility model, a limiting rod is fixedly installed at the bottom of the placing disc. A threaded hole is formed in the outer wall of the limiting rod. A limiting bolt is arranged on the outer wall of the limiting rod, and the limiting bolt is threadedly connected to the threaded hole. A limiting ring is arranged at the bottom of the limiting rod.

[0010] As a further solution of the utility model, three third rotating blocks are fixedly installed at the bottom of the placing disc. The outer walls of the three third rotating blocks are rotatably connected to a support rod. The inner side outer wall of the support rod is rotatably connected to a connecting strip, and one end of the connecting strip is rotatably connected to the outer wall of the limiting ring.

[0013] Compared with the prior art, the beneficial effects of the utility model are as follows:

[0014] 1) For the mine terrain measuring device that is convenient to erect, the protective case can rotate under the restriction of the fixed plate. By rotating the protective cases on both the left and right sides, the protective cases perform an arc-shaped movement. After the connecting rod is stressed, due to the restriction of the connecting block, one end of the connecting rod will push the sliding column upward, so that the measuring instrument is lifted upward from the wrapped state. While being able to adjust the height, it is more convenient to take out the measuring instrument. And when the measuring device is not in use, the measuring instrument will be wrapped by the protective case and is not affected by the external environment.

[0015] 2) For the mine terrain measuring device that is convenient to erect, before opening the support rod of the measuring device, the opening angle of the support foot can be selected according to the actual environment, that is, the height of different limiting bolts is adjusted.

When the connecting rod 4 rotates, it can drive the sliding column 7 to rise, lifting the measuring instrument 8 at the top of the sliding column 7. Through the fastening bolt 5, the connection between the connecting block 3 and the connecting rod 4 can be fixed, and thus the sliding column 7 that has risen to a certain position can be fixed, ensuring that the measuring instrument 8 will not fall due to its own weight.

[0026] Embodiment 2

[0027] Refer to Figure 3 and Figure 4 On the basis of Embodiment 1, it is further obtained that a limiting rod 12 is fixedly installed at the bottom of the placement plate 1. A threaded hole 13 is provided on the outer wall of the limiting rod 12. A limiting bolt 14 is provided on the outer wall of the limiting rod 12, and the limiting bolt 14 is threadedly connected to the threaded hole 13. A limiting ring 15 is provided at the bottom of the limiting rod 12. Three third rotating blocks 16 are fixedly installed at the bottom of the placement plate 1. The outer walls of the three third rotating blocks 16 are rotatably connected to a support rod 17. The inner side outer wall of the support rod 17 is rotatably connected to a connecting strip 18, and one end of the connecting strip 18 is rotatably connected to the outer wall of the limiting ring 15. Two fixed cylinders 19 are fixedly installed on the outer side outer wall of the support rod 17. A threaded rod 20 is rotatably connected to the inner wall of the left fixed cylinder 19.

After the connecting rod 4 is stressed, due to the restriction of the connecting block 3, one end of the connecting rod 4 pushes the sliding column 7 upward, thereby lifting the measuring instrument 8 from the wrapped state upward. After lifting to a certain height, tighten the fastening bolt 5 to fix the connection between the connecting block 3 and the connecting rod 4, and then the position of the sliding column 7 that has risen to a certain position can be fixed, ensuring that the measuring instrument 8 will not fall due to its own weight and affect the measurement. Before opening the support rod 17 of the measuring device, the opening angle of the support feet 22 can be selected according to the actual environment, that is, adjust the height of different limit bolts 14. After determining the height of the limit bolts 14, during the process of opening the support rod 17, the connecting strip 18 will drive the limit ring 15 to move upward and stop moving at the bottom of the limit bolt 14. And by rotating the threaded rod 20, the fixing block 23 can be moved downward along the direction of the support rod 17, and the distance between the support feet 22 and the support rod 17 can be adjusted flexibly.
