Description

Technical Field

[0002] Urban and rural planning refers to the process of rationally arranging and planning urban and rural areas, aiming to achieve sustainable development in urban and rural areas, improve the quality of life of residents and protect the environment. It involves land use, architectural design, transportation planning, environmental protection, infrastructure planning and other aspects to ensure that the development of urban and rural areas is coordinated with environmental, economic and social needs. In the process of urban and rural planning, the main thing is to plan the land, and special measurement equipment is needed to measure the project planning during the planning process.

[0003] At present, the existing measuring equipment includes a measuring instrument, a tripod, a base, a circular level and three foot screws. The base is arranged on the top of the tripod, the circular level is connected to the base through three foot screws, and the measuring instrument is arranged on the upper part of the circular level. After the tripod is opened, coarse leveling is performed by extending and retracting the tripod, and then fine leveling is performed by rotating the three foot screws. During the fine leveling process, the three foot screws need to be repeatedly rotated to complete the leveling.

[0004] However, since the process of fine leveling is rather cumbersome, workers need to continuously change different positions for measurement during the measurement process. If they need to repeatedly turn the three foot screws multiple times after each change of position to complete the leveling, it not only increases the time required for measurement, but also increases the physical burden on the workers, causing physical fatigue and increasing the risk of operational errors, affecting the subsequent measurement accuracy.

[0058] The adjusting block 21 is rotated counterclockwise to move the adjusting block 21 from one end of the through slot 20 to the second position mark 39. During the movement of the adjusting block 21, the fixing of the balancing ball 6 is released, so that the balancing ball 6 drives the adjusting disk 4 to swing, and the pressure inside the plurality of guide cylinders 8 is balanced by the fluid in the annular storage chamber 16, so that the adjusting disk 4 returns to the horizontal state.

[0059] The adjusting block 21 is rotated counterclockwise so that the adjusting block 21 moves from the second position mark 39 to the other end of the through slot 20, disconnecting the connection between the guide cylinders 8 and fixing the position of the adjusting disk 4;

[0060] The adjusting block 21 is rotated clockwise to return the adjusting block 21 from the other end of the through slot 20 to the first position mark 38, thereby fixing the balancing ball 6 and completing the fine leveling operation.

[0061] Working principle: When in use, first open the tripod 1, adjust the length of each telescopic rod to achieve rough leveling, then rotate the adjusting block 21 clockwise to move the adjusting block 21 from the first position mark 38 to one end of the through slot 20, the adjusting block 21 drives the inner gear ring 19 to rotate clockwise, the inner gear ring 19 drives the multiple first gears 23 to rotate clockwise, each first gear 23 drives the corresponding rotating cylinder 11 to rotate clockwise through the second slider 33, each rotating cylinder 11 drives the corresponding partition 12 and the second through hole 15 to rotate clockwise, each second through hole 15 coincides with the corresponding first through hole 14, so that the multiple guide cylinders 8 are connected, at the same time, the multiple first gears 23 drive the second gears 24 to rotate counterclockwise when rotating clockwise, the second gear 24 drives the multiple first arc grooves 28 and the corresponding second arc grooves 30 to rotate counterclockwise, so that each first slider 30 slides in the second arc groove 30.

[0062] The adjusting block 21 is rotated counterclockwise to move the adjusting block 21 from one end of the through groove 20 to the second position mark 39. During the movement of the adjusting block 21, the multiple first gears 23 drive the second gear 24 to rotate clockwise when rotating counterclockwise, and the second gear 24 drives the multiple first arc grooves 28 and the corresponding second arc grooves 30 to rotate clockwise, so that each first slider 30 enters the first arc groove 28 from the second arc groove 30 and slides in the first arc groove 28, driving the corresponding clamping bar 26 to move in the direction away from the connecting rod 7, slowly releasing the connecting rod 7, thereby slowly releasing the fixation of the balancing ball 6, so that the balancing ball 6 drives the adjusting disk 4 to swing slowly, and the pressure inside the multiple guide cylinders 8 is balanced by the fluid in the annular storage chamber 16, and the adjusting disk 4 returns to the horizontal state. At the same time, when each first gear 23 rotates counterclockwise, it drives the slide groove 32 to rotate counterclockwise, so that the second slider 33 slides to the front end of the slide groove 32 rotating clockwise.

[0063] The adjusting block 21 is rotated counterclockwise so that the adjusting block 21 moves from the second position mark 39 to the other end of the through groove 20, and the multiple first gears 23 are driven to rotate counterclockwise through the inner gear ring 19. Each first gear 23 drives the rotating cylinder 11 to rotate counterclockwise through the second slider 33, so that each second through hole 15 is disconnected from the corresponding first through hole 14, thereby disconnecting the connection between the guide cylinders 8 and fixing the position of the adjusting disk 4. At the same time, each first slider 30 continues to slide in the second arc groove 30.

[0064] The adjusting block 21 is rotated clockwise to return from the other end of the through slot 20 to the first position mark 38, driving the plurality of clamping bars 26 to move toward the connecting rod 7, clamping and fixing the connecting rod 7, thereby fixing the balancing ball 6 and completing the fine leveling operation.
