Description

Technical Field

[0001] This utility model relates to the field of measuring benchmark technology, and in particular to an auxiliary benchmark for engineering measurement. Background Technology

[0002] In engineering surveying, levels and benchmarks are often used together. Most existing benchmarks are simple, cone-shaped structures inserted into the ground, which are relatively inexpensive. However, they are often difficult to place stably and require support and fixation by surveyors. Furthermore, the benchmarks need to be kept vertical during measurement, and workers need to support and stabilize them for extended periods, making their use inconvenient. Therefore, an auxiliary benchmark for engineering surveying is needed to solve these problems. Summary of the Invention

[0003] The technical problem to be solved by this utility model is that existing benchmarks require workers to provide auxiliary support during use to ensure their stability.

[0004] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is: an auxiliary marker for engineering measurement, including a tripod support mechanism, a first spherical seat fixed on the top of the support mechanism, and a first ball head rotatably arranged in the first spherical seat. A marker assembly is fixedly connected to the first ball head, and the marker assembly passes through the center of the first ball head. A counterweight ball and a positioning cone are fixedly connected to the bottom end of the marker assembly. A clamping structure is provided between the first spherical seat and the first ball head.

[0005] Preferably, the benchmark assembly includes connected rod sections, the counterweight ball is connected to the bottommost rod section, the positioning cone is connected to the bottom of the counterweight ball, and the centers of the counterweight ball, the positioning cone and the rod section are located on the same axis.

[0006] Preferably, the bottom ends of the rod section and the counterweight ball are coaxially fixed with threaded heads, and the top ends of the rod section, the counterweight ball and the positioning cone are all provided with threaded holes that are adapted to the threaded heads.

[0007] Preferably, a mounting plate is provided at the middle of the first ball head, and the mounting plate has a mounting hole for the threaded head to pass through. The two rod sections are respectively connected to the top and bottom of the mounting plate.

[0008] Preferably, the inner top and inner bottom of the first ball head are both coaxially fixed with annular reinforcing ribs.

[0009] Preferably, the clamping structure includes a first threaded seat disposed on the outer wall of the first spherical seat and a locking bolt threadedly connected to the first threaded seat, wherein the first threaded seats are evenly distributed around the axis of the first spherical seat.

[0010] Preferably, the screw end of the first lug is fixedly connected with a rubber anti-slip block.

[0011] Preferably, the support mechanism includes an annular support plate fixedly connected to the bottom of the first spherical seat, legs inclinedly connected to the bottom of the support plate, and pads connected to the bottom of the legs. The legs are evenly distributed around the center of the support plate, and at least three legs are connected to the bottom of the support plate.

[0012] Preferably, a second threaded seat is fixedly provided at the bottom of the support plate, a threaded head is fixedly provided coaxially at the top of the support leg, a threaded hole adapted to the threaded head is provided at the bottom of the second threaded seat, and a connecting threaded head and a threaded hole are provided between the support leg and the pad.

[0013] Preferably, a second spherical seat is fixedly connected to the pad, and a second ball head is rotatably connected inside the second spherical seat. The second ball head is connected to the threaded hole at the bottom end of the support leg through the threaded head.

[0014] This utility model provides an auxiliary benchmark for engineering surveying, which has the following beneficial effects.

[0015] 1. The outriggers are installed on the second threaded seat via threaded heads, thereby supporting the support plate. In turn, the first spherical seat is supported by the support mechanism. The marker assembly is directly assembled on the mounting plate. By lowering the counterweight spherical seat, it achieves an automatic vertical effect under gravity, without the need for manual support, thus facilitating the use of auxiliary markers for engineering surveying.

[0016] 2. The first ball head can be firmly fixed by using locking bolts and rubber anti-slip blocks, so that after the first ball head is naturally vertical under the action of gravity, it can be further fixed to avoid unnecessary shaking during the surveying process.

[0017] 3. A foot is movably connected to the bottom of the outrigger via a second ball head and a second spherical seat to increase the support area. The foot can easily fit into the ground and, together with the anti-slip mat, form an anti-slip effect, effectively improving the stability of the outrigger support.

[0018] 4. The marker assembly itself is assembled using threaded head and threaded hole, and is mounted on the mounting plate. The legs and the second threaded seat are also assembled, as are the second ball head and the legs. This makes the overall auxiliary marker for engineering measurement a modular design, which allows for easy disassembly when not in use to reduce space occupation and facilitates portability.

[0024] Example 1: Please see Figures 1-4 In this embodiment of the present invention, an auxiliary marker for engineering surveying includes a support mechanism 1. The support mechanism 1 includes a support plate 2. A first spherical seat 3 is fixedly connected to the top surface of the support plate 2. A first ball head 5 adapted to the first spherical seat 3 is movably connected to the inner side of the first spherical seat 3. The first ball head 5 is hollow and its top and bottom are both open. A mounting plate 6 is fixedly connected to the inner side of the first ball head 5. The mounting plate 6 has a mounting hole 7, which is centrally located. A marker assembly 8 is assembled and installed inside the first ball head 5. The marker assembly 8 includes multiple rod sections 9, a counterweight ball 10, and a positioning cone 11. The top of the rod section 9, the top of the counterweight ball 10, and the top of the positioning cone 11 are all provided with threaded holes 12. The bottom of the rod section 9 and the bottom of the counterweight ball 10 are all fixedly connected with threaded heads 13. The threaded heads 13 correspond to and fit the threaded holes 12. Two adjacent rod sections 9 are assembled and installed by the threaded heads 13 and the threaded holes 12. The two bottom rod sections 9 are clamped on the mounting plate 6 and the corresponding threaded heads 13 pass through the mounting holes 7. The counterweight ball 10 is assembled and installed at the bottom of the bottom rod section 9 by the threaded heads 13 and the threaded holes 12. The positioning cone 11 is assembled and installed at the bottom of the counterweight ball 10 by the threaded heads 13 and the threaded holes 12.

[0025] The support leg 19 is installed on the second threaded seat 18 through the threaded head 13, thereby supporting the support plate 2. The first spherical seat 3 can be supported by the support mechanism 1. The marker assembly 8 is directly assembled on the mounting plate 6. By lowering the counterweight ball seat 10, it forms an automatic vertical effect under gravity, without the need for manual support, thus facilitating the use of auxiliary markers for engineering measurement.

[0026] The first ball head 5 has a reinforcing rib 14 for internal fixation.

[0027] By adding reinforcing ribs 14, the structural strength of the first ball head 5 can be increased.

[0028] The first spherical seat 3 is circumferentially fixedly connected to a first threaded seat 15, which is located on the central plane of the first spherical seat 3. The first threaded seat 15 is internally threaded with a matching locking bolt 16.

[0029] The locking bolt 16 is inserted into the first spherical seat 3 and abuts against the outer wall of the first ball head 5. The bolt head of the locking bolt 16 is fixedly connected with a rubber anti-slip block 17. The first spherical seat 3 is provided with a clearance hole for the locking bolt 16 to pass through. The threaded end of the locking bolt 16 can be set as a concave spherical surface that is compatible with the first spherical seat 3.

[0030] The first ball head 5 can be firmly fixed by the locking bolt 16 and the rubber anti-slip block 17, so that the first ball head 5 can be further fixed after it naturally becomes vertical under the action of gravity, thus avoiding unnecessary shaking during the surveying process.

[0031] The support mechanism 1 also includes a second threaded seat 18 and a support leg 19. Three second threaded seats 18 are arranged circumferentially at an angle and are all fixedly connected to the bottom surface of the support plate 2. The support leg 19 corresponds to the second threaded seat 18. The second threaded seat 18 is adapted to the threaded head 13. A second ball head 20 is assembled and installed at the bottom end of the support leg 19. A second spherical seat 21 adapted to the second ball head 20 is movably sleeved on the outside of the second ball head 20. A pad 22 is fixedly connected to the bottom of the second spherical seat 21. An anti-slip pad 4 is fixedly connected to the bottom surface of the pad 22.

[0032] A foot 22 is movably connected to the bottom of the support leg 19 via a second ball head 20 and a second spherical seat 21 to increase the support area. The foot 22 can easily fit into the ground and, together with the anti-slip mat 4, form an anti-slip effect, effectively improving the stability of the support leg 19.

[0033] A threaded head 13 is fixedly connected to the top of the support leg 19 and the second ball head 20. A threaded hole 12 is also provided at the bottom of the support leg 19. The support leg 19 is threadedly connected to the second threaded seat 18 through the threaded head 13, and the second ball head 20 is threadedly connected to the threaded hole 12 at the bottom of the support leg 19 through the threaded head 13.

[0034] The marker assembly 8 itself is assembled by the threaded head 13 and the threaded hole 12 and is assembled on the mounting plate 6. At the same time, the support leg 19 and the second threaded seat 18 are also assembled, and the second ball head 20 and the support leg 19 are also assembled. Thus, the overall auxiliary marker for engineering measurement is designed as an assembly, which makes it easy to disassemble when not in use to reduce space occupation and make it easy to carry.

[0035] Example 2: In this embodiment of the utility model, an auxiliary marker for engineering surveying is provided, wherein the support leg 19 and the pole section 9 are identical, thus making the accessories interchangeable and facilitating the processing of the auxiliary marker for engineering surveying.

[0036] Example 3: In this embodiment of the utility model, an auxiliary marker for engineering measurement has a support leg 19 that can be extended by itself or by the rod section 9, thereby controlling the support height of the support mechanism 1.

[0037] Example 4: In this embodiment of the invention, an auxiliary marker for engineering measurement has pole sections 9 that can be freely combined to adjust the total length and height of the marker assembly 8.

[0038] The working principle of this utility model is as follows: In use, take the support plate 2, and assemble the support leg 19 on the bottom surface of the support plate 2 through the cooperation of the second threaded seat 18 and the threaded head 13. At the bottom end of the support leg 19, the second ball head 20 is connected through the cooperation of the threaded hole 12 and the threaded head 13. At this time, the support plate 2 is supported by the support leg 19. The second ball seat 21 and the second ball head 20 are connected by the pad 22 to the ground. The pad 22 is connected to the ground by the anti-slip pad 4. At this time, the support mechanism 1 stands on the ground. Further, the marker assembly 8 is assembled on the first ball head 5. First, assemble the two bottom rod sections 9 on the mounting plate 6. Then, assemble the weighted ball 10 and the positioning cone 11. At this time, under the action of gravity, the first ball head 5 rotates in the first ball seat 3, so that the rod section 9 is in a vertical position. At this time, rotate the locking bolt 16. Under the action of the first threaded seat 15, the rubber anti-slip block 17 is pressed against the outer wall of the first ball head 5 to form a fixed effect. Further assemble the pole section 9 upwards, so that the pole assembly 8 extends and completes the vertical placement of the pole assembly 8. At this time, the level instrument can be used in conjunction with the pole to carry out the corresponding surveying and measurement.
