Description

Technical Field

[0001] The utility model relates to the technical field of measurement and mapping, in particular to a benchmark for building measurement and mapping. Background Art

[0002] Before large-scale construction projects are constructed, surveying and mapping engineers must measure and draw topographic maps and provide other information before making decisions, planning and designing. During the construction process, various surveying and measurements are often required to ensure that the construction is carried out strictly according to the plan. After the project is completed, the project needs to be measured to ensure the quality of the project. Therefore, engineering surveying and mapping runs through the entire construction process and plays a very important role.

[0003] In the process of engineering surveying and mapping, a kind of engineering surveying and mapping benchmark is needed. However, in the prior art, most engineering surveying and mapping benchmarks are fixed by inserting the cone at the bottom of the benchmark into the soil. Therefore, the stability of the benchmark during surveying and mapping cannot be guaranteed, and it is impossible to directly know whether the benchmark is in a vertical state, and the length of the benchmark cannot be adjusted. Measurement errors may occur during the measurement process, thereby reducing the work efficiency of construction surveying and mapping. Therefore, we propose a new benchmark for building surveying and mapping. Utility Model Content

The rotating grooves are set in three, and the three rotating grooves are evenly arranged in a circle at the bottom of the mounting seat, and the cross-section of the rotating groove is spherical.

[0008] As a further description of the above technical solution, the support assembly includes a support leg, a rotating ball, a support rod, and a slider.

[0013] Compared with the prior art, the utility model has the following beneficial effects:

[0014] 1. By setting up benchmark one, benchmark two, hanging hammer, electric telescopic rod, cone head, etc., when starting the measurement and mapping work, first place the device to the position to be measured. The hanging hammer can intuitively know whether benchmark one and benchmark two are in a vertical state. Then, by extending the electric telescopic rod, the cone head is driven to move downward and fit with the ground. The cone head can be used to locate the position of the surveying point. At the same time, by extending and shortening benchmark two in the inner cavity of benchmark one and fixing it, the overall height can be adjusted to facilitate measurement work, reduce the floor space of the device, and the overall length, and facilitate carrying.

[0015] 2. By setting a rotating component, a supporting component, a fixing component, etc., when performing surveying and mapping work, first move the device to the surveying site through the universal wheel, rotate the threaded rod, so that the internal threaded ring moves downward along the threaded rod, and at this time, the internal threaded ring pushes the sliding block slidably connected in its inner cavity to rotate through the sliding groove, thereby pushing the supporting rod to squeeze the supporting leg, driving the rotating ball to rotate in the rotating groove, so that the supporting frame moves outward along the rotating ball at its end to open, so that the mounting seat can be fixed and supported at the required position, and then the drilling nails are rotated again to continuously rotate the drilling nails downward and penetrate into the ground. When the three drilling nails are buried under the ground, the reliability of the support of the device is greatly improved. At the same time, the length of the three drilling nails entering the ground can be adjusted according to the specific conditions of the ground on site, so that the benchmark one and the benchmark two remain in a vertical state, making the support more stable and facilitating surveying and mapping work.

[0024] See also Figure 1-4 The utility model provides a technical solution: a benchmark for building measurement and mapping, including a mounting base 1, a rotating component 2 is provided at the bottom of the mounting base 1, an electric telescopic rod 4 is fixedly connected to the bottom of the rotating component 2, and a cone head 5 is fixedly connected to the bottom of the electric telescopic rod 4. When the measurement and mapping work starts, the cone head 5 is driven to move downward and fit the ground by extending the electric telescopic rod 4, so that the cone head 5 can be used to locate the position of the surveying point. A supporting component 3 is provided around the bottom of the mounting base 1, and a fixing component 9 is provided on the supporting component 3. A benchmark rod 1 6 is fixedly connected to the top of the mounting base 1, and a benchmark rod 2 7 is slidably connected to the inner cavity of the benchmark rod 1 6.

The adjusting hole 14 and the adjusting hole 2 15 are fixedly connected through an adjusting knob 13. When the device is not in use, the benchmark rod 2 7 is slid into the inner cavity of the benchmark rod 1 6, so that the volume of the device becomes smaller, and at the same time, the benchmark rod 2 7 can be protected to a certain extent, so that the device is easy to carry. When starting the surveying and mapping work, the second benchmark 7 is pulled out from the inner cavity of the first benchmark 6, and the first benchmark 6 and the second benchmark 7 can be fixed by screwing the adjusting knob 13 into the second adjusting hole 15 and the corresponding adjusting hole 14. A hanging hammer 10 is fixedly connected to one side of the bottom of the mounting base 1. When starting the surveying and mapping work, the device is first placed at the position to be measured, and the hanging hammer 10 can be used to intuitively know whether the first benchmark 6 and the second benchmark 7 are in a vertical state.

[0025] Specifically, Figure 1As shown, a warning light 8 is fixedly connected to the top of the benchmark 2 7. Several warning stickers 12 are evenly fixedly connected to the side walls of the mounting base 1. When measuring and mapping work is performed in a location with poor light, after the device is fixed, the warning light 8 can be turned on to prevent other personnel from accidentally touching the device, resulting in inaccurate measurement data. At the same time, the warning stickers 12 can also play a good warning role. Tool boxes 11 are symmetrically fixedly connected to both sides of the top of the mounting base 1, and the staff can place the tools in the tool box 11.

[0026] Specifically, Figure 2 , Figure 3 As shown, the rotating assembly 2 includes a threaded rod 2.1 and an internal threaded ring 2.2. The threaded rod 2.1 is rotatably connected to the bottom of the mounting seat 1 through a bearing. The internal threaded ring 2.2 is slidably sleeved on the threaded rod 2.1, and the internal threaded ring 2.2 is meshed with the threaded rod 2.1 through a threaded groove, and the bottom of the threaded rod 2.1 is fixedly connected to the top of the electric telescopic rod 4. When the mounting seat 1 needs to be supported, the threaded rod 2.1 is rotated to make the internal threaded ring 2.2 move downward along the threaded rod 2.1.

[0027] A sliding groove 2.3 is formed around the surface of the internal thread ring 2.2, and the cross section of the sliding groove 2.3 is semicircular. A rotating groove 16 is formed at the bottom of the mounting seat 1. There are three rotating grooves 16, and the three rotating grooves 16 are evenly arranged at the bottom of the mounting seat 1 in a circular shape. The cross section of the rotating groove 16 is spherical.

[0028] The supporting assembly 3 comprises a supporting leg 3.1, a rotating ball 3.2, a supporting rod 3.3 and a sliding block 3.4. The rotating ball 3.2 is rotatably connected to the inner cavity of the rotating groove 16, one side of the rotating ball 3.2 is fixedly connected to the supporting leg 3.1, one side of the supporting leg 3.1 is fixedly connected to the supporting rod 3.3, one end of the supporting rod 3.3 is fixedly connected to the sliding block 3.4, the sliding block 3.4 is set to be spherical, and the sliding block 3.4 is slidably connected to the inner cavity of the sliding groove 2.3, and the bottom of the supporting leg 3.1 is fixedly connected to the universal wheel 3.5, which facilitates moving the device to the place where measurement and mapping are required. When in use, the device is first moved to the place where measurement and mapping is required by means of the universal wheel 3.5, and the threaded rod 2.1 is rotated to make the internal threaded ring 2.2 move downward along the threaded rod 2.1. At this time, the internal threaded ring 2.2 pushes the slider 3.4 slidably connected in its inner cavity to rotate through the slide groove 2.3, thereby pushing the support rod 3.3 to squeeze the support leg 3.1, driving the rotating ball 3.2 to rotate in the rotating groove 16, so that the support leg 3.1 moves outward along the rotating ball 3.2 at its end to open, and the mounting base 1 can be fixedly supported at the required position.

[0029] Specifically, Figure 4As shown, the fixing assembly 9 includes a mounting plate 9.1, a fixing hole 9.2, and a ground-drilling nail 9.3. The mounting plate 9.1 is fixedly sleeved on the lower part of the leg 3.1 and is located above the universal wheel 3.5. The mounting plate 9.1 is provided with a through fixing hole 9.2. The ground-drilling nail 9.3 penetrates the fixing hole 9.2 and is engaged with the fixing hole 9.2 through a threaded groove. After the mounting seat 1 is fixedly supported at the desired position, the ground-drilling nail 9.3 is rotated to rotate the ground-drilling nail 9.3 downward continuously and penetrate into the ground. When the three ground-drilling nails 9.3 are buried into the ground, the reliability of the support of the device is greatly improved. At the same time, the length of the three ground-drilling nails 9.3 entering the ground can be adjusted according to the specific conditions of the ground on site, so that the benchmark 1 6 and the benchmark 2 7 remain in a vertical state, making the support more stable and convenient for measurement and mapping work.

[0030] It should be noted that the utility model is a benchmark for building measurement and mapping. When in use, the device is first moved to the place where measurement and mapping is required through the universal wheel 3.5, and then the electric telescopic rod 4 is extended to drive the cone head 5 to move downward and fit with the ground. The cone head 5 can be used to locate the position of the surveying point, and the threaded rod 2.1 is rotated to make the internal threaded ring 2.2 move downward along the threaded rod 2.1. At this time, the internal threaded ring 2.2 pushes the slider 3.4 slidably connected in its inner cavity to rotate through the slide groove 2.3, thereby pushing the support rod 3.3 to squeeze the support leg 3.1, driving the rotating ball 3.2 to rotate in the rotating groove 16, so that the support leg 3.1 moves outward along the rotating ball 3.2 at its end to open, and the mounting seat 1 can be fixedly supported at the required position. At this time, turn the ground drill nail 9.3 again, rotate the ground drill nail 9.3 downward continuously, and go deep into the ground. When the three ground drill nails 9.3 are buried in the ground, the reliability of the support of the device is greatly improved. At the same time, the length of the three ground drill nails 9.3 entering the ground can be adjusted according to the specific conditions of the ground on site. Then, through the hanging hammer 10, it can be intuitively known whether the benchmark 1 6 and the benchmark 2 7 are in a vertical state, so that the benchmark 1 6 and the benchmark 2 7 are kept in a vertical state, making the support more stable and convenient for measurement and mapping. When starting the measurement and mapping work, pull the benchmark 2 7 out of the inner cavity of the benchmark 1 6, and screw the adjustment knob 13 into the adjustment hole 2 15 and the corresponding adjustment hole 1 14 to fix the benchmark 1 6 and the benchmark 2 7 for measurement and mapping. At the end of the work, slide the benchmark 2 7 into the inner cavity of the benchmark 1 6, so that the volume of the device becomes smaller, and the benchmark 2 7 can also be protected to a certain extent, so that the device is easy to carry.
