Problems solved by technology

[0003] The tripod is one of the devices often used in the measurement process. The tripod is used to stabilize the measuring instrument to ensure the measurement effect. During the measurement process, it is often necessary to adjust the height of the tripod. The height adjustment of the ordinary tripod needs to change the length of the bracket. It is cumbersome to adjust three times. After the adjustment, it needs to be re-fixed and adjusted horizontally, resulting in low overall measurement efficiency; if you need to measure multiple sets of data with different heights, you need to adjust the bracket multiple times and fix it for debugging, which is very inconvenient

Embodiment 1

[0030] see Figure 1~4 , a lifting measuring instrument support tripod, including a support 4, three telescopic frames 3 are hinged at the bottom of the support 4, and the three telescopic frames 3 are distributed in an equilateral triangle, and the telescopic frames 3 can be extended or shortened, thereby adjusting the whole of the tripod Height; the bottom end of the telescopic frame 3 is fixedly connected with the ground rod 1, which is suitable for the use of tripods in different environments. It is convenient to insert and fix in the soil when used on the soil and keep stable. The outer end of the outer end is fixedly connected with pedal 2, which is convenient for foot to step on and bear force;

[0031] The top of the support 4 is fixedly provided with a fixed seat 5, and the center position of the top of the fixed seat 5 is provided with a circular groove, and a rotating cylinder 7 is connected in the circular groove through the first bearing 6, and a fixed cylinder is...

Embodiment 2

[0034] see Figure 5-6 , on the basis of Example 1, the instrument placement seat 14 is disc-shaped, the outer wall of the instrument placement seat 14 is fixedly socketed with an angle ring 16, and the angle ring 16 is printed with an angle, and the top side wall of the screw rod 10 is also fixedly connected There is a pointer 17 that cooperates with the angle ring 16; the screw 10 does not rotate when it is raised and lowered, and the relative angle of the pointer 17 remains unchanged. When the angle of the instrument placement seat 14 changes, it is convenient to calibrate the angle by setting the angle ring 16, and it is also convenient for subsequent different orientations Measurement, angle adjustment accuracy is higher.

Embodiment 3

[0036] The angle between the three telescopic frames 3 of the existing tripod is generally kept relatively fixed by an angle-limiting structure. This type of tripod has good stability, but in order to ensure the level of the measuring instrument, only the length of the telescopic frame 3 can be adjusted. When operating a tripod, the adjustment of the telescopic frame 3 and the observation of the spirit level 15 often cannot be carried out at the same time, and it often takes repeated attempts to ensure the level, which is very troublesome to adjust and the accuracy is not high; It is limited and can be adjusted arbitrarily, but it will move as soon as the force is applied after adjustment, and the stability is not good; in order to improve the above-mentioned shortcomings of the existing tripod,

[0037] see Figure 7-8 , on the basis of Embodiment 1, one of the telescopic frames 3 and the other two telescopic frames 3 are respectively connected with mutually hinged connecting...

Abstract

The invention relates to the technical field of measurement, and discloses a lifting type measuring apparatus supporting tripod which comprises a support. Three expansion brackets are hinged to the bottom of the support. A fixed base is fixedly arranged on the top of the support. A round groove is formed in the center of the top of the fixed base. A drum is rotationally connected into the round groove through a first bearing. A fixed cylinder is arranged in the drum. The bottom end of the fixed cylinder is fixedly connected with the fixed base. A screw matched with the fixed cylinder is arranged in the fixed cylinder. A slider is fixedly connected with the bottom of the side wall of the screw. A guide notch matched with the slider is formed in the side wall of the fixed cylinder. A nut isfixedly connected with the inner top of the drum. The screw penetrates through the nut and is in threaded connection with the nut. The top end of the screw is connected with an apparatus placing rack.The height of the measuring apparatus can be adjusted by rotating the drum to move the screw up and down, different heights can be conveniently measured, the height can be easily and conveniently adjusted, there is no need to adjust the length of the expansion brackets, and the measuring efficiency can be easily improved.

Description

technical field [0001] The invention relates to the technical field of measurement, in particular to a lifting measuring instrument support tripod. Background technique [0002] Surveying is the science of studying the shape and size of the earth and determining the points on the ground (including the air, underground and seabed). The science and technology of collecting, processing, managing, updating and utilizing relevant information. In modern engineering construction, measurement is essential. [0003] The tripod is one of the devices often used in the measurement process. The tripod is used to stabilize the measuring instrument to ensure the measurement effect. During the measurement process, it is often necessary to adjust the height of the tripod. The height adjustment of the ordinary tripod needs to change the length of the bracket. It is cumbersome to adjust three times. After the adjustment, it needs to be re-fixed and adjusted horizontally, resulting in low ove...
