Description

Technical Field

[0001] This utility model belongs to the field of engineering surveying and mapping technology, and in particular relates to a bracket for engineering surveying and mapping equipment. Background Technology

[0002] Engineering surveying technology refers to the application of modern engineering surveying techniques to acquire various geographic and spatial data required for engineering projects, and to process and analyze this data to ultimately generate graphic and digital information reflecting the actual conditions of the engineering site. This information is of significant reference value for the design, planning, construction, management, and subsequent maintenance of the project. Engineering surveying equipment is an important tool for acquiring the geographic and spatial data required for engineering projects. The main types of equipment include instruments such as rangefinders, levels, theodolites, total stations, and GPS measuring instruments. Supports for engineering surveying equipment play a crucial role in engineering surveying and mapping, providing stable and accurate support for the surveying equipment. Tripods are the most common type of support in engineering surveying, consisting of three legs and a pan-tilt head. They are typically used to support surveying equipment such as levels, theodolites, and total stations. Tripods have advantages such as good stability and easy adjustment, and are suitable for various terrain and climatic conditions.

[0003] The problem with existing technology is that if the support and surveying equipment are not securely fixed, the surveying equipment may shake or shift during use, resulting in inaccurate measurement results. This error may accumulate and eventually lead to a decrease in the accuracy of the entire surveying project. Utility Model Content

[0004] To address the problems existing in the prior art, this utility model provides a bracket for engineering surveying equipment, which has the advantage of stably fixing the surveying equipment. It solves the problem that if the bracket and the surveying equipment are not firmly fixed, the surveying equipment may shake or shift during use, resulting in inaccurate measurement results. Such errors may accumulate and eventually lead to a decrease in the accuracy of the entire surveying project.

[0005] This utility model is implemented as follows: a support for engineering surveying equipment includes a base, a support, and a disc. The support is rotatably connected to the bottom of the base via a rotating shaft at equal intervals. The disc is fixedly connected to the top of the base. Three mounting blocks are fixedly connected at equal intervals on the outer surface of the disc. Each mounting block has a cavity inside. The cavity is equipped with a snap-fit ​​mechanism and a pushing mechanism. A surveying instrument is mounted on the top of the disc. The bottom of the surveying instrument has a groove on one side corresponding to the mounting block. Insertion holes are provided on both the left and right sides of the inner wall of the groove.

[0006] As a preferred embodiment of this utility model, the locking mechanism includes a compression spring, two connecting blocks, two insert blocks, and two connecting posts. The two connecting blocks are respectively fixedly connected to both ends of the compression spring. The two insert blocks are respectively fixedly connected to the opposite sides of the two connecting blocks, and the other side of the insert blocks penetrates and extends into the insertion hole inside the groove at the bottom of the surveying instrument. The two connecting posts are respectively fixedly connected to the top of the two connecting blocks. The connecting posts are used in conjunction with the pushing mechanism. By setting the locking mechanism, the bottom of the surveying instrument can be fixed by the mounting blocks, thereby stably fixing the surveying instrument to the top of the disc.

[0007] In a preferred embodiment of this invention, the pushing mechanism includes two cylinders, two swing rods, a crossbar, two squeezing columns, and an electric cylinder. The two cylinders are fixedly connected to both sides inside the cavity. The two swing rods are rotatably connected to the surfaces of the two cylinders. The crossbar is located at the bottom of the two swing rods. The two squeezing columns are fixedly connected to the top of the crossbar and located on the side of the two swing rods that are far apart from each other. The outer surface of the squeezing column is in contact with the surface of the swing rod. The electric cylinder is fixedly connected to the inner wall of the cavity, and the output end of the electric cylinder is fixedly connected to the surface of the crossbar. The side of the swing rod closest to the connecting column is sleeved on the surface of the connecting column. By setting up the pushing mechanism, the three mounting blocks are simultaneously moved by the locking mechanisms inside, and then the surveying instrument can be fixed.

[0008] As a preferred embodiment of this utility model, the surface of the swing rod is provided with a connecting hole, and the inner wall of the connecting hole is in contact with the surface of the connecting column. By providing the connecting hole, the swing rod and the connecting column can be connected, and then the movement of the swing rod can drive the connecting column to move.

[0009] As a preferred embodiment of this utility model, the inner wall of the cavity is fixedly connected to two limiting rods, and the two limiting rods are respectively located at the two ends of the two connecting blocks. The connecting blocks are slidably connected to the surface of the limiting rods. By setting the limiting rods, the movement of the connecting blocks can be restricted, thereby preventing the connecting blocks from shifting when moving.

[0010] As a preferred embodiment of this invention, magnetic blocks are fixedly connected to the sides of the two connecting blocks that are close to each other, and the magnetic poles of the two magnetic blocks are opposite. By setting the magnetic blocks, the two connecting blocks can be attracted to each other after they are close to each other, thereby fixing the two connecting blocks.

[0011] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0012] 1. This utility model solves the problem that if the support and the surveying equipment are not firmly fixed, the surveying equipment may shake or shift during use, resulting in inaccurate measurement results.

[0019] To further understand the invention content, features and effects of this utility model, the following embodiments are provided, and detailed descriptions are given in conjunction with the accompanying drawings.

[0020] The structure of this utility model will now be described in detail with reference to the accompanying drawings.

[0021] like Figures 1 to 4As shown in the figure, an engineering surveying equipment bracket provided by this utility model includes a base 1, a bracket 2 and a disc 3. The bracket 2 is rotatably connected to the bottom of the base 1 via a rotating shaft. The disc 3 is fixedly connected to the top of the base 1. Three mounting blocks 4 are fixedly connected at equal intervals on the outer surface of the disc 3. A cavity 5 is opened inside the mounting block 4. A snap-fit ​​mechanism 6 and a pushing mechanism 7 are provided inside the cavity 5. A surveying instrument 8 is provided on the top of the disc 3. A groove 9 is opened on the bottom of the surveying instrument 8 corresponding to one side of the mounting block 4. Insertion holes 10 are opened on both the left and right sides of the inner wall of the groove 9.

[0022] refer to Figure 2 and Figure 4 The snap-fit ​​mechanism 6 includes a compression spring 601, two connecting blocks 602, two insert blocks 603, and two connecting posts 604. The two connecting blocks 602 are fixedly connected to both ends of the compression spring 601, and the two insert blocks 603 are fixedly connected to the opposite sides of the two connecting blocks 602. The other side of the insert block 603 extends through and into the insertion hole 10 inside the groove 9 at the bottom of the surveying instrument 8. The two connecting posts 604 are fixedly connected to the top of the two connecting blocks 602. The connecting posts 604 are used in conjunction with the pushing mechanism 7.

[0023] Using the above solution: by setting the snap-fit ​​mechanism 6, the bottom of the surveying instrument 8 can be fixed by the mounting block 4, thereby stably fixing the surveying instrument 8 to the top of the disc 3.

[0024] refer to Figure 4 The pushing mechanism 7 includes two cylinders 701, two swing rods 702, a crossbar 703, two squeezing columns 704, and an electric cylinder 705. The two cylinders 701 are fixedly connected to both sides inside the cavity 5. The two swing rods 702 are rotatably connected to the surfaces of the two cylinders 701. The crossbar 703 is located at the bottom of the two swing rods 702. The two squeezing columns 704 are fixedly connected to the top of the crossbar 703 and located on the side of the two swing rods 702 that are far apart from each other. The outer surface of the squeezing column 704 is in contact with the surface of the swing rod 702. The electric cylinder 705 is fixedly connected to the inner wall of the cavity 5, and the output end of the electric cylinder 705 is fixedly connected to the surface of the crossbar 703. The side of the swing rod 702 near the connecting column 604 is sleeved on the surface of the connecting column 604.

[0025] The above solution is adopted: by setting up a pushing mechanism 7, the three mounting blocks 4 are simultaneously driven to move the snap-fit ​​mechanism 6 inside, and then the surveying instrument 8 can be fixed.

[0026] refer to Figure 4 The surface of the swing rod 702 is provided with a connecting hole 11, and the inner wall of the connecting hole 11 is in contact with the surface of the connecting post 604.

[0027] By adopting the above solution: by setting the connection hole 11, the swing rod 702 can be connected to the connecting column 604, and then the movement of the swing rod 702 can drive the connecting column 604 to move.

[0028] refer to Figure 4 Two limiting rods 12 are fixedly connected to the inner wall of the cavity 5, and the two limiting rods 12 are located at the two ends of the two connecting blocks 602 respectively. The connecting blocks 602 are slidably connected to the surface of the limiting rods 12.

[0029] By adopting the above solution, the movement of the connecting block 602 can be restricted by setting the limiting rod 12, thereby preventing the connecting block 602 from deviating when moving.

[0030] refer to Figure 4 Two connecting blocks 602 are fixedly connected to magnetic blocks 13 on their sides that are close to each other, and the magnetic poles of the two magnetic blocks 13 are opposite.

[0031] The above solution is adopted: by setting up magnetic blocks 13, the two connecting blocks 602 can be attracted to each other after they come close together, thereby fixing the two connecting blocks 602.

[0032] The working principle of this utility model:

[0033] In use, the electric cylinder 705 is activated, which drives the crossbar 703 and the two extruding columns 704 to move. As the two extruding columns 704 move, they press against the surfaces of the two swing rods 702, causing the two swing rods 702 to swing around the two cylinders 701. After the swing rods 702 move, they can press against the surface of the connecting column 604 through the inner wall of the connecting hole 11 on their surface, thereby causing the two connecting columns 604 to move towards each other. After the connecting columns 604 move... The two connecting blocks 602 can be moved, and the movement of the connecting blocks 602 drives the two insert blocks 603 into the cavity 5. At this time, the connecting blocks 602 squeeze the compression spring 601 when they move, and are attracted by the two magnetic blocks 13. The surveying instrument 8 can then be installed with the disc 3 by aligning the groove 9 at its bottom with the mounting block 4. Then the electric cylinder 705 retracts, and the insert blocks 603 are inserted into the insertion holes 10 on the surface of the groove 9 to fix the surveying instrument 8.

[0034] In summary, the support for the surveying equipment in this project, through the coordinated use of a base 1, support 2, disc 3, mounting block 4, cavity 5, snap-fit ​​mechanism 6, pushing mechanism 7, surveying instrument 8, groove 9, insertion hole 10, connecting hole 11, limiting rod 12, and magnetic block 13, solves the problem that if the support and surveying equipment are not securely fixed, the surveying equipment may shake or shift during use, leading to inaccurate measurement results. This error may accumulate and ultimately reduce the accuracy of the entire surveying project.
