Description

Technical Field

[0001] This utility model relates to the technical field of three-phase separator devices, specifically to a double centering bracket for surveying equipment. Background Technology

[0002] The double centering bracket mainly consists of a support frame and a plug located below the support frame. The support frame is the main structure of the bracket, and its design is robust and stable to ensure the accuracy and safety of the surveying equipment. An upper centering bracket and a lower centering bracket are located on the central axis of the support frame, and different surveying tools can be mounted on the upper and lower centering brackets respectively.

[0003] A search revealed a utility model patent with publication number CN209762676U, which discloses a double-alignment bracket for surveying equipment. The bracket includes a support frame and a plug positioned below the support frame. The support frame has an upper alignment head and a lower alignment head along its central axis. The upper alignment head is vertically positioned at the top of the support frame for mounting a satellite receiver, and the lower alignment head is vertically positioned at the bottom of the support frame for mounting a ranging prism. The double-alignment bracket has two alignment heads, one for mounting the satellite receiver and the other for mounting the ranging prism. This allows for obtaining positioning coordinates by receiving satellite signals and for observing distance and direction by using a total station in conjunction with the ranging prism for backsight target aiming. In control surveying on operating railway lines, where observation time is limited to a 2-3 hour observation window, the double-alignment bracket allows for simultaneous execution of two levels of control surveying, improving observation efficiency and saving observation time.

[0004] Although the aforementioned patent uses a double centering bracket to perform two levels of control measurements simultaneously, improving observation efficiency and saving observation time, the existing double centering bracket requires separate tightening connections when installing and fixing multiple surveying tools. This results in low installation efficiency of the surveying tools on the double centering bracket. Furthermore, the double centering bracket cannot drive the installed and fixed surveying tools to adjust their angles during use. The support column connected to the bottom of the double centering bracket needs to be rotated together to complete the angle adjustment, and the horizontal level between the support column and the ground needs to be readjusted. Otherwise, the accuracy of the test data of the surveying tools will be affected.

[0005] Therefore, it is necessary to propose a double centering bracket for surveying equipment to solve the above problems. Utility Model Content

[0006] The purpose of this invention is to provide a double-centering bracket for surveying equipment. Through the cooperation of internal parts of the connecting mechanism, multiple surveying tools can be simultaneously installed and fixed on the main body of the double-centering bracket. By adjusting the cooperation of these internal parts, the main body of the double-centering bracket can drive the surveying tools to adjust their horizontal angle during use, without needing to simultaneously adjust the support rod. This improves the accuracy of the surveying tool test data. This addresses the problems in existing double-centering brackets where multiple surveying tools need to be individually tightened, resulting in low installation efficiency. Furthermore, the double-centering bracket cannot drive the fixed surveying tools to adjust their angle during use; the support column connected to the bottom of the double-centering bracket needs to be rotated to complete the angle adjustment, and the horizontal alignment between the support column and the ground needs to be readjusted, otherwise the accuracy of the surveying tool test data will be affected.

[0007] To achieve the above objectives, this utility model provides the following technical solution: a double centering bracket for surveying equipment, comprising a double centering bracket body, a support rod rotatably connected to the bottom end of the double centering bracket body, a connecting mechanism rotatably connected to both sides of the outer wall of the double centering bracket body, extending through to the top end of the double centering bracket body and through to the docking columns at the bottom of multiple surveying equipment, and an adjusting mechanism slidably connected to the bottom end of the double centering bracket body, extending through the double centering bracket body to the outer wall of the support rod and sleeved with the outer wall of the support rod;

[0008] The connecting mechanism includes multiple connecting columns, which are located on both sides of the outer and inner walls of the double centering bracket body and extend into the interior of the double centering bracket body. A connecting rod is machined between the multiple connecting columns and slidably connected to the interior of the double centering bracket body. A return spring is sleeved on the outer wall of the connecting rod and connected between the inner walls of the double centering bracket body. Protrusions are machined at both ends of the connecting columns located on the inner walls of the double centering bracket body and extend into the inner walls of the double centering bracket body.

[0009] The adjustment mechanism includes a rotating ring, which is rotatably sleeved on the outer wall of the support rod and extends into the interior of the double centering bracket body. The rotating ring is machined at the bottom end of the double centering bracket body. A support column is slidably connected to the top end of the rotating ring and extends into the interior of the double centering bracket body. A limit ring is machined at the bottom end of the rotating ring and slidably connected to the interior of the rotating ring. Multiple limit posts are machined at the top end of the limit ring and distributed around the outer wall of the support column.

[0010] Preferably, the connecting mechanism further includes a pull ring, which is machined on the side of the connecting column away from the main body of the double centering bracket. The main body of the double centering bracket is internally slidably connected to a fixed column, which is located at the top and bottom of the connecting column and the connecting rod, respectively, and is located on one side of the protrusion. A telescopic spring is fixedly connected between the fixed column and the main body of the double centering bracket.

[0011] Preferably, the adjustment mechanism further includes a support spring, which is connected and fixed between the bottom end of the limiting ring and the rotating ring. The outer wall of the rotating ring is machined with multiple limiting blocks around its perimeter and fits against the inner wall of the support rod.

[0012] Preferably, the top of the double centering bracket body is provided with multiple docking grooves that match the docking posts at the bottom of the surveying tool, and a buffer pad is provided at the docking point. The inner wall of the double centering bracket body is provided with grooves that match the protrusions, and the inner wall of the support rod is provided with multiple limiting grooves that match the limiting posts.

[0013] Preferably, the inner wall of the double centering bracket body is provided with a sliding groove that matches the fixed column, and the two sides of the docking column at the bottom of the surveying tool are provided with a fixing groove that matches the fixed column. The inner wall of the double centering bracket body is provided with a reset groove that matches the support spring.

[0014] Preferably, the double-centering bracket body and the inside of the rotating ring are provided with telescopic grooves that match the support column, the outer wall of the support rod is provided with multiple slots that match the limiting blocks, and the rotating ring is rotatably connected to the outer wall of the support rod through ball bearings. The outer wall of the rotating ring is machined with small protrusions.

[0015] The technical effects and advantages provided by this utility model in the above technical solution are as follows:

[0016] 1. By connecting and installing multiple surveying tools onto the double centering bracket body, the pull ring pushes the connecting column to compress the return spring, causing the connecting column to slide out of the inner wall of the double centering bracket body via the connecting rod. This causes the connecting column to move the protrusion out of the inner wall of the double centering bracket body, releasing the compression on the fixed column. This releases the compression on the telescopic spring, and the telescopic spring returns to its original position, pushing the fixed column to move. The fixed column then passes through the double centering bracket body to the docking column at the bottom of the surveying tool, thus completing the connection and fixation between the surveying tool and the double centering bracket body. Then, rotating the pull ring 90 degrees causes the connecting column and connecting rod to rotate, causing the protrusion on the other side of the connecting column to rotate 90 degrees and separate from the groove on the inner wall of the double centering bracket body, thus completing the connection and fixation between the surveying tool and the double centering bracket body.

[0017] 2. The surveying tool is installed inside the double centering bracket body by docking. The docking column presses against the support column. The support column is forced to push the limiting ring, which in turn compresses the support spring and moves it. This causes the limiting ring to move the limiting column out of the inner wall of the support rod, releasing the rotation limit between the rotating ring and the support rod. Then, the rotating ring is rotated. The rotation of the rotating ring, through the mutual cooperation between the limiting block and the inner wall of the support rod, ensures that the angle between each rotation of the rotating ring is consistent. At the same time, the rotation of the rotating ring drives the double centering bracket body to rotate, thus completing the angle adjustment operation of the surveying tool on the double centering bracket body.

Detailed Implementation

[0026] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.

[0027] This utility model provides, for example Figure 1-5The double centering bracket for surveying equipment shown includes a double centering bracket body 1, a support rod 101 rotatably connected to the bottom end of the double centering bracket body 1, a connecting mechanism 2 rotatably connected to both sides of the outer wall of the double centering bracket body 1, extending through to the top end of the double centering bracket body 1 and through to the docking columns at the bottom of multiple surveying equipment, and an adjusting mechanism 3 slidably connected to the bottom end of the double centering bracket body 1, extending through the double centering bracket body 1 to the outer wall of the support rod 101 and sleeved with the outer wall of the support rod 101;

[0028] The connecting mechanism 2 includes multiple connecting columns 201. The multiple connecting columns 201 are located on both sides of the outer wall and inner wall of the double centering bracket body 1 and penetrate into the interior of the double centering bracket body 1. Connecting rods 203 are machined between the multiple connecting columns 201 and are slidably connected to the interior of the double centering bracket body 1. A return spring 205 is sleeved on the outer wall of the connecting rod 203 and connected between the inner walls of the double centering bracket body 1. Protrusions 204 are machined at both ends of the connecting columns 201 located on the inner wall of the double centering bracket body 1 and penetrate into the inner wall of the double centering bracket body 1.

[0029] The adjustment mechanism 3 includes a rotating ring 301, which is rotatably sleeved with the outer wall of the support rod 101 and extends into the interior of the double centering bracket body 1. It is machined at the bottom end of the double centering bracket body 1. The top end of the rotating ring 301 is slidably connected to a support column 302, which extends through the rotating ring 301 into the interior of the double centering bracket body 1. The bottom end of the rotating ring 301 is machined with a limiting ring 303, which is slidably connected to the interior of the rotating ring 301. The top end of the limiting ring 303 is machined with multiple limiting posts 304, which are distributed around the outer wall of the support column 302.

[0030] By cooperating with each other among the internal parts of the connecting mechanism 2, multiple surveying tools can be simultaneously installed and fixed on the double centering bracket body 1. By cooperating with each other among the internal parts of the adjusting mechanism 3, the double centering bracket body 1 can drive the surveying tools to adjust their horizontal angles during use without having to drive the support rod 101 to adjust simultaneously, thereby improving the accuracy of the surveying tool test data.

[0031] Refer to the instruction manual appendix Figure 1-5 The connecting mechanism 2 also includes a pull ring 202, which is machined on the side of the connecting column 201 away from the double centering bracket body 1. The double centering bracket body 1 is internally slidably connected to a fixed column 206, which is located at the top and bottom of the connecting column 201 and the connecting rod 203, respectively, and is located on one side of the protrusion 204. A telescopic spring 207 is connected and fixed between the fixed column 206 and the double centering bracket body 1. Through the mutual cooperation between the internal parts of the connecting mechanism 2, the installation and fixation between the bottom docking column of the surveying tool and the double centering bracket body 1 can be completed.

[0032] Refer to the instruction manual appendix Figure 1-5 The adjustment mechanism 3 also includes a support spring 305, which is connected and fixed between the bottom end of the limiting ring 303 and the rotating ring 301. Multiple limiting blocks 306 are machined around the outer wall of the rotating ring 301 and fit against the inner wall of the support rod 101. Through the mutual cooperation between the internal parts of the adjustment mechanism 3, the angle between each rotation of the rotating ring 301 on the support rod 101 can be consistent when the rotating ring 301 rotates on the support rod 101 through the limiting blocks 306.

[0033] Refer to the instruction manual appendix Figure 1-5 The top of the double centering bracket body 1 is provided with multiple docking grooves that match the docking posts at the bottom of the surveying tools, and a buffer pad is provided at the docking point. The inner wall of the double centering bracket body 1 is provided with a groove that matches the protrusion 204, and the inner wall of the support rod 101 is provided with multiple limiting grooves that match the limiting post 304. The top of the double centering bracket body 1 is provided with multiple docking grooves that match the docking posts at the bottom of the surveying tools, and a buffer pad is provided at the docking point, which facilitates the docking and connection of multiple surveying tools with the double centering bracket body 1.

[0034] Refer to the instruction manual appendix Figure 1-5 The inner wall of the double centering bracket body 1 is provided with a sliding groove that matches the fixed post 206, and the two sides of the docking post at the bottom of the surveying tool are provided with fixing grooves that match the fixed post 206. The inner wall of the double centering bracket body 1 is provided with a reset groove that matches the support spring 305. The sliding groove on the inner wall of the double centering bracket body 1 that matches the fixed post 206, and the fixing grooves on the two sides of the docking post at the bottom of the surveying tool that match the fixed post 206, facilitate the fixed post 206 to pass through the inner wall of the double centering bracket body 1 to the docking post at the bottom of the surveying tool, thereby completing the connection and fixation between the surveying tool and the double centering bracket body 1.

[0035] Refer to the instruction manual appendix Figure 1-5 The double-centering bracket body 1 and the rotating ring 301 have telescopic grooves inside that match the support column 302. The outer wall of the support rod 101 has multiple slots that match the limiting blocks 306. The rotating ring 301 is rotatably connected to the outer wall of the support rod 101 via ball bearings. The outer wall of the rotating ring 301 is machined with small protrusions. The rotating ring 301 is rotatably connected to the outer wall of the support rod 101 via ball bearings, which facilitates the limiting and fixing between the rotating ring 301 and the support rod 101.

[0036] The working principle of this practical application is as follows:

[0037] Refer to the instruction manual appendix Figure 1-5By connecting and installing multiple surveying tools onto the double-centering bracket body 1, the pull ring 202 pushes the connecting column 201 to compress the return spring 205, causing the connecting column 201 to slide out of the inner wall of the double-centering bracket body 1 via the connecting rod 203. This causes the connecting column 201 to move the protrusion 204 out of the inner wall of the double-centering bracket body 1, releasing the compression on the fixing column 206. This releases the compression on the telescopic spring 207, allowing the telescopic spring 207 to return to its original position and push the fixing column 206 out of the inner wall of the double-centering bracket body 1. The fixed column 206 is moved so that it passes through the body of the double centering bracket 1 to the docking column at the bottom of the surveying tool, thus completing the connection and fixation between the surveying tool and the body of the double centering bracket 1. Then, the pull ring 202 is rotated 90 degrees. The rotation of the pull ring 202 drives the connecting column 201 and the connecting rod 203 to rotate, so that the protrusion 204 on the connecting column 201 on the other side rotates 90 degrees and separates from the groove on the inner wall of the double centering bracket 1, thus completing the connection and fixation between the surveying tool and the body of the double centering bracket 1.

[0038] Refer to the instruction manual appendix Figure 1-5 The surveying tool is installed inside the double centering bracket body 1 by docking. The docking column presses against the support column 302. The support column 302 is forced to push the limiting ring 303, which in turn presses against the support spring 305, causing it to contract and move. This causes the limiting ring 303 to move the limiting column 304 out of the inner wall of the support rod 101, releasing the rotation limit between the rotating ring 301 and the support rod 101. Then, the rotating ring 301 is rotated. The rotation of the rotating ring 301, through the cooperation of the limiting block 306 and the inner wall of the support rod 101, ensures that the angle between each rotation of the rotating ring 301 is consistent. At the same time, the rotation of the rotating ring 301 drives the double centering bracket body 1 to rotate, thus completing the angle adjustment operation of the surveying tool on the double centering bracket body 1.

[0039] The foregoing description only illustrates certain exemplary embodiments of the present invention. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
