Description

Technical Field

[0001] The utility model relates to the field of tripod supports, and more specifically, it relates to a tripod support for surveying and mapping engineering. Background Technique

[0002] During the process of building construction surveying and mapping, various data acquisitions are often involved. During the data measurement process, various measuring instruments are generally used. The measuring instruments are generally used in conjunction with tripod supports to keep the measuring instruments level, so as to facilitate the measurement of data. Existing measuring instruments are generally installed on the tripod support through bolts. There is a lack of a protection structure on the tripod support. When the surveying personnel are using the tripod support and the measuring instrument, they may temporarily leave the measuring instrument due to some other things, so that the measuring instrument lacks protection. When the tripod support and the measuring instrument are affected by the external environment, they are prone to tipping over, so that the measuring instrument will be knocked and damaged, affecting the normal use of the measuring instrument and the smooth progress of the surveying and mapping project. At the same time, existing tripod supports often adjust the height of the measuring instrument by adjusting the distance between the three legs of the tripod support. It is inconvenient to quantify the adjustment of the distance between the three legs, so it is inconvenient to adjust the height of the equipment, thus affecting the quick adjustment of the measuring instrument.

The second threaded rod 9 is rotationally connected with the moving frame 5 through a bearing. The second threaded rod 9 passes through the installation block 6, and the second threaded rod 9 is threadedly connected with the installation block 6. A fixing hole 20 is formed in the installation block 6;

[0035] Specifically, when installing the measuring instrument, according to the opening positions on the measuring instrument itself, rotate the first threaded rod 7. Through the two threads with opposite helix directions arranged on the first threaded rod 7 and the threaded connection with the moving frame 5, drive the two moving frames 5 to approach or move away from each other, so that the installation blocks 6 approach or move away from each other horizontally. Rotate the second threaded rod 9 arranged on the moving frame 5. Through the two threads with opposite helix directions arranged on the second threaded rod 9 and the threaded connection with the installation block 6, rotate the second threaded rod 9 to drive the two installation blocks 6 to approach or move away from each other longitudinally, so as to align the fixing hole 20 formed in the installation block 6 with the opening of the instrument itself. Insert bolts into the fixing hole 20 and the opening of the instrument itself to complete the installation and connection of the instrument and the entire triangular bracket. When changing the height of the instrument as needed, push the connecting pipe 15 to move along the platform plate 1 to make the instrument reach the required position. Insert bolts into the positioning holes 17 to fix the position of the connecting pipe 15 and complete the adjustment of the height of the instrument. When using the instrument, rotate the installation frame 4 through the rotational cooperation of the first rotation column 19 and the first rotation hole 18, so as to change the orientation of the instrument.

[0036] Please refer to Figures 1-5, as an implementation method for protecting the measuring instrument: Second rotating columns 21 are provided at both ends of the connecting block 11, second rotating holes 22 are formed in the extension piece 10, the second rotating columns 21 and the second rotating holes 22 cooperate with each other, the protection plate 13 and the airbag 14 are both arranged on the middle plate 12, limiting holes 23 are formed in both the extension piece 10 and the connecting block 11, threads are provided in the limiting holes 23, the second rotating columns 21 and the second rotating holes 22 are rotatably connected, a fixing column 24 is fixedly arranged at the lower end of the middle plate 12, the fixing column 24 passes through the connecting block 11, and the fixing column 24 and the connecting block 11 are rotatably connected, a spring 25 is arranged between the protection plate 13 and the middle plate 12, an installation column 26 is fixedly arranged on the middle plate 12, the protection plate 13 is sleeved and installed on the installation column 26, the spring 25 is sleeved and installed on the installation column 26, threads are provided at the tops of both the installation column 26 and the fixing column 24, and a clamping block 27 is rotatably arranged on the connecting block 11;

[0037] Specifically, when the surveyor needs to temporarily leave the measurement position, through the rotational connection between the second rotating column 21 and the second rotating hole 22, the middle plate 12 is kept perpendicular to the platform plate 1. Insert the bolt into the limiting holes 23 formed in the connecting block 11 and the extension piece 10. After inserting the bolt into the limiting hole 23, rotate the clamping block 27 to block the rotation of the middle plate 12, thereby fixing the middle plate 12. When the external environment impacts the measuring instrument, the protection plate 13 is pushed to move by the external impact, the protection plate 13 compresses the spring 25, and the external impact is resisted by the elastic force of the spring 25 itself. At the same time, when the entire bracket topples, the damage to the measuring instrument is reduced through the contact between the airbag 14 arranged on the middle plate 12 and the measuring instrument.

[0038] In summary, when the whole is in use:

[0039] When installing the instrument, according to the opening positions on the measuring instrument itself, rotate the first threaded rod 7. Through the two threads with opposite helix directions provided on the first threaded rod 7 and the threaded connection with the moving frame 5, drive the two moving frames 5 to approach or move away from each other, so that the mounting blocks 6 approach or move away from each other horizontally. Rotate the second threaded rod 9 provided on the moving frame 5. Through the two threads with opposite helix directions provided on the second threaded rod 9 and the threaded connection with the mounting blocks 6, rotate the second threaded rod 9 to drive the two mounting blocks 6 to approach or move away from each other longitudinally, so as to align the fixing holes 20 formed on the mounting blocks 6 with the openings on the instrument itself. Insert the bolt into the fixing holes 20 and the openings on the instrument itself to complete the installation and connection of the instrument and the entire triangular bracket. When changing the height of the instrument as needed, push the connecting pipe 15 to move along the platform plate 1 to make the instrument reach the required position. Insert the bolt into the positioning hole 17 to fix the position of the connecting pipe 15 and complete the adjustment of the instrument height.

[0040] When using the instrument, rotate the mounting frame 4 through the rotational fit between the first rotating column 19 and the first rotating hole 18, thereby changing the orientation of the instrument. Remove the bolt in the limiting hole 23, rotate the connecting block 11 through the cooperation between the second rotating hole 22 and the second rotating column 21, and lay down the protection structure. Rotate the clamping block 27 so that the clamping block 27 no longer restricts the protection plate 13 and the intermediate plate 12. Rotate the intermediate plate 12 through the fixed column 24 and the connecting block 11, turn one side of the protection plate 13 upwards, and make the protection plate 13 and the intermediate plate 12 level with the platform plate 1. Reinsert the bolt into the limiting hole 23 to fix the position of the intermediate plate 12, thereby facilitating the use of the protection plate 13 and the intermediate plate 12 as a platform, and recording the data generated by the measurement by placing a pen and paper on the protection plate 13.

[0041] When the surveyor needs to temporarily leave the measurement position, keep the intermediate plate 12 perpendicular to the platform plate 1 through the rotational connection between the second rotating column 21 and the second rotating hole 22. Insert the bolt into the limiting hole 23 opened on the connecting block 11 and the extension piece 10. Insert the bolt into the limiting hole 23 and rotate the clamping block 27 to block the rotation of the intermediate plate 12, thereby fixing the intermediate plate 12. When the external environment impacts the measuring instrument, the protection plate 13 is pushed to move by the external impact, and the protection plate 13 compresses the spring 25. The elastic force of the spring 25 itself resists the external impact. At the same time, when the entire bracket topples, the contact between the airbag 14 provided on the intermediate plate 12 and the measuring instrument reduces the damage of the measuring instrument.

[0042] In all the above-mentioned solutions, for the connection between two components, welding, the cooperation connection of bolts and nuts, bolt or screw connection, or other well-known connection methods can be selected according to the actual situation, which will not be elaborated one by one here. For those mentioned as fixed connections above, welding is preferably considered. Although the embodiments of the present invention have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principle and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
