Technical Field

[0001] The present invention relates to the technical field of measuring devices, and particularly relates to a geodetic instrument. Background Art

[0002] Geodetic instruments are devices used to measure points on the earth's surface and are widely used in fields such as land surveying and mapping, construction engineering, and geological exploration. Traditional geodetic instruments are usually supported by a bracket, and the free end of the support rod of the bracket is usually designed to be pointed so as to be easily inserted into the ground to fix the instrument.

[0003] However, this design has the following problems in actual use: 1. Since the free end of the support rod is pointed, it is easy to cause accidental injury during transfer or handling, especially in an environment with a dense population or limited operating space, increasing the safety risk for operators; 2. Geodetic instruments usually need to be frequently moved between different measurement points. Due to the large weight of the instrument itself, frequent handling not only increases the workload of the operator but also may cause damage to the instrument or a decrease in its accuracy.

One end of each of the plurality of support feet 28 is circumferentially and equidistantly hinged to the mounting table 1. During use, the angles of the plurality of support feet 28 can be adjusted to stably support the device by the plurality of support feet 28. The number of support feet 28 is three. The fixed end of the telescopic member 3 is connected to the bottom of the mounting table 1, and the telescopic end of the telescopic member 3 is connected to the traveling mechanism 11. Among them, the telescopic member 3 is an electric telescopic rod or a hydraulic telescopic rod. When it is necessary to transfer the device, after adjusting the traveling mechanism 11, the length of the telescopic member 3 is adjusted so that the traveling mechanism 11 contacts the ground, changing from the support feet 28 touching the ground to the traveling mechanism 11 touching the ground, which is convenient for the movement and transfer of the device, eliminating the need for surveyors to carry it and reducing the work intensity of surveyors. The adjusting mechanism 4 is connected to the bottom of the mounting table 1, is arranged outside the telescopic member 3, and is respectively hinged to the plurality of support feet 28. The adjusting mechanism 4 is used to adjust the angles at which the plurality of support feet 28 are deployed. By means of the adjusting mechanism 4, the deployment angles of the plurality of support feet 28 can be adjusted. When the device is stably supported, it can also adapt to the height of surveyors, facilitating the use of the measuring instrument 2 by surveyors to measure the earth's topography.

[0029] See Figures 1 to 4 , the adjusting mechanism 4 includes an adjusting sleeve 5, a fixed tube 6, a connecting ring 7, and a plurality of adjusting rods 8. One end of the fixed tube 6 is fixed to the bottom of the mounting table 1, the fixed tube 6 is sleeved outside the telescopic member 3, the adjusting sleeve 5 is threadedly connected to the fixed tube 6, the connecting ring 7 is rotatably connected to the adjusting sleeve 5, one end of each of the plurality of adjusting rods 8 is hinged to the adjusting sleeve 5, and the free ends of the plurality of adjusting rods 8 are hinged to the corresponding support feet 28.

[0030] A convex ring 9 is provided on the outer side of the adjusting sleeve 5, and a ring groove 10 is provided on the inner side of the connecting ring 7.

The connecting seat 12 is connected to the telescopic end of the telescopic member 3. One ends of the plurality of protective connecting frames 19 are respectively hinged to the connecting seat 12, enabling the protective connecting frames 19 to rotate. When not in use, they can be rotated and retracted to reduce the occupied space. The ends of the plurality of protective connecting frames 19 are connected to the corresponding shock absorption components 24, and the shock absorption components 24 are connected to the corresponding traveling wheels.

The positioning member 13 is used to position the plurality of protective connecting frames 19. When the protective connecting frame 19 rotates to the horizontal position, rotate the positioning member 13 to position the protective connecting frame 19 and keep the protective connecting frame 19 in a horizontal state, so that the traveling wheels can contact the ground, facilitating the transfer of this device.

[0034] The protective connecting frame 19 includes a protective seat 20, a first connecting rod 22 and a second connecting rod 23. The free end of the first connecting rod 22 is hinged to the connecting seat 12, the free end of the first connecting rod 22 is connected to the protective seat 20, and both ends of the second connecting rod 23 are respectively connected to the protective seat 20 and the shock absorption component 24. A protective groove 21 is provided in the protective seat 20, and the protective groove 21 is matched with the free end of the corresponding support foot 28. After rotating and unfolding the protective connecting frame 19, adjust the unfolding angle of the support foot 28 so that the end of the support foot 28 is received in the protective groove 21 to play a protective role and facilitate the transfer of this device.

When the ground where the equipment is placed is uneven, the length of each support foot 28 can be adjusted by sliding the lower support feet 30 according to the actual situation. A bolt (not marked) for limiting the sliding of the lower support feet 30 is provided on the upper support feet 29.

[0039] During use, rotate the adjusting sleeve 5. The adjusting sleeve 5 rotates along the fixed tube 6. The fixed tube 6 is threadedly connected to the adjusting sleeve 5. The two ends of the adjusting rod 8 are respectively hinged to the connecting ring 7 and the support feet 28. The rotation angles of the corresponding support feet 28 are adjusted through a plurality of adjusting rods 8, so that the plurality of support feet 28 rotate and unfold, which can stably support the equipment. When it is necessary to transfer to the next place for surveying and mapping, rotate the protective connection frame 19 until the protective connection frame 19 rotates to the horizontal. The connection frame drives the boat wheels 18 to rotate together. The handle 17 drives the positioning tube 16 and the positioning plate 14 to rotate to position the protective connection frame 19, so that the protective connection frame 19 maintains a horizontal state. Control the telescopic member 3 to extend, driving the traveling mechanism 11 to move down and contact the ground. Until the plurality of support feet 28 leave the ground and rise to a proper position, adjust the angles of the plurality of support feet 28 through the adjusting mechanism 4, and slightly retract the plurality of support feet 28 toward the side close to the fixed tube 6. While the plurality of support feet 28 rotate inward, the bottom tips of the plurality of support feet 28 are received in the protective grooves 21 of the protective seat 20, playing a protective role and facilitating the transfer of the equipment.
