Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of building surveying and mapping, in particular to a line-laying device for surveying and mapping. Background Art
[0002] Layout work is the process of accurately transferring the geometric positions on the design drawings to the actual site in a construction or engineering project. Theodolite is a commonly used device for layout work. It is an instrument used to measure horizontal and vertical angles and can accurately place and measure the axis of the building. Theodolite is often set up on a tripod during use. During installation, the theodolite needs to be adjusted to a horizontal level and laser alignment is used to ensure that the theodolite is set up directly above the reference point.
[0003] The tripod brackets used in general projects do not have a fine-tuning function, and the bracket length needs to be repeatedly changed to adjust the theodolite to a horizontal level. Moreover, if the level is not aligned with the reference point after adjustment, manual translation is required, which can easily destroy the previously adjusted level and require a secondary operation.

[0024] See also Figures 1 to 4The utility model provides a technical solution: a line-laying device for surveying and mapping, comprising a flat plate 1, a mounting plate 11 and a leveling housing 16, characterized in that: an X-axis crossbar 2 is fixedly connected to one side of the flat plate 1, one end of the X-axis crossbar 2 is fixedly connected to an X-axis smooth rod 3, the other end of the X-axis crossbar 2 is movably connected to an X-axis screw 4, the outer surface of the X-axis screw 4 is threadedly connected to an X-axis ball nut 22, the top of the X-axis ball nut 22 is fixedly connected to a Y-axis crossbar 7, one end of the Y-axis crossbar 7 is fixedly connected to a Y-axis smooth rod 8, the other end of the Y-axis crossbar 7 is movably connected to a Y-axis screw 9, the outer surface of the Y-axis screw 9 is threadedly connected to a Y-axis ball nut 23, the top of the Y-axis ball nut 23 is fixedly connected to a mounting plate 11, and a mounting hole 13 is provided in the middle of the upper surface of the mounting plate 11. By setting the X-axis screw 4 and the Y-axis screw 9, the support leg 18 can be moved without moving. The horizontal position of the mounting plate 11 can be directly adjusted in the case of a lack of adjustment, which will not affect the leveling of the theodolite and does not require adjustment by moving the support legs 18. The operation process is optimized. One end of the X-axis screw 4 passes through the X-axis cross bar 2 and is fixedly connected to the X-axis screw head 5. One end of the Y-axis screw 9 passes through the Y-axis cross bar 7 and is fixedly connected to the Y-axis screw head 21. The X-axis screw head 5 and the Y-axis screw head 21 are arranged to facilitate the rotation of the X-axis screw 4 and the Y-axis screw 9 to adjust the position of the mounting plate 11. The outer surface of the X-axis optical rod 3 is movably connected to the X-axis slider 6. The top of the X-axis slider 6 is fixedly connected to the Y-axis cross bar 7. The outer surface of the Y-axis optical rod 8 is movably connected to the Y-axis slider 10. The top of the Y-axis slider 10 is fixedly connected to the mounting plate 11. The number of the X-axis slider 6, the X-axis ball nut 22, the Y-axis slider 10 and the Y-axis ball nut 23 are all two, and the number of sliders and ball nuts is set to two. , to ensure the stability of the structure, the lower surface of the evaluation plate 1 is fixedly connected with a hinge frame 14, and the lower side of the hinge frame 14 is hinged with a leveling shell 16 through a hinge pin 15, and the internal movability of the leveling shell 16 is connected with a leveling screw 19, and one end of the leveling screw 19 passes through the leveling shell 16 and is fixedly connected with a leveling screw head 17, and the outer surface of the leveling screw 19 is meshed with a support foot 18 through a straight tooth 20, and the length of the support foot 18 is adjusted by a worm gear structure, and the worm gear has a certain self-locking ability, which is sufficient to support the weight of the theodolite and prevent safety problems or damage to the instrument due to height sliding. The number of the leveling shell 16 and the support foot 18 is three, which are distributed in a ring below the plate 1 and are at an angle of 120° to each other. Through the principle of triangular stability, three support feet 18 are provided to provide uniform support, which further enhances the stability of the device and its adaptability to various terrains.
[0025] During installation, first open the three legs 18 to a suitable angle. While ensuring the height of the theodolite, open the legs as much as possible and place them above the preset point. After ensuring the stability of the device, directly install the theodolite on the mounting plate 11 and fix it through the mounting hole 13. Observe whether the theodolite is level by observing the circular leveler on the theodolite. Adjust the length of the three legs 18 in turn by rotating the leveling screw head 17 according to the tilt. Raise the leg 18 that is leaning towards the bubble in the circular level or lower the leg 18 that is away from it. After the circular level shows level, turn on the laser calibrator to adjust the horizontal position of the theodolite. The X-axis screw head 5 and the Y-axis screw head 21 can adjust the horizontal position of the mounting plate 11, and then adjust the horizontal position of the theodolite. After adjusting to the laser alignment mark, the subsequent marking and laying-out work can be carried out. Such adjustment can move the horizontal position of the theodolite without changing the positions of the three legs 18, and there is no need to readjust the legs 18, which greatly increases work efficiency. Through the surveying and mapping laying-out device, the theodolite can be installed conveniently and quickly, and the accuracy of the installation of the theodolite can be ensured. The design takes into account the convenience of operation, the stability of the structure, and the safety and reliability during use. It is very suitable for precise position adjustment in surveying and mapping operations.
