Abstract
Description
Technical Field
[0001] This utility model relates to the field of mining surveying technology, and in particular to a multifunctional measuring rod assembly and structure for mining surveying. Background Technology
[0002] In mine surveying, RTK centering rods, used in conjunction with RTK equipment, perform high-precision positioning measurements, enabling the creation of mine topographic maps. In mine roadway surveying, they can determine parameters such as the location and direction of roadways. In mine settlement monitoring, they can monitor settlement changes by measuring the coordinates of the same point at different times. Their applications are diverse. Furthermore, some centering rods integrate devices such as leveling bubbles to assist in leveling the rod and ensure measurement accuracy. This is a type of measuring rod assembly structure used in mine surveying. However, in existing technologies using RTK centering rods to assist RTK measurements, strong winds can cause the rods to sway, potentially leading to tipping over and damaging the RTK equipment, as well as fatigue damage. Therefore, this paper proposes a multifunctional measuring rod assembly and structure for mine surveying to address these issues. Utility Model Content
[0003] The technical problem to be solved by this utility model overcomes the existing defects and can effectively solve the problems in the background art.
[0004] To achieve the above objectives, the technical solution adopted by this utility model is as follows:
[0005] A multifunctional measuring rod assembly and structure for mine surveying includes an RTK centering rod. A fixed base is located at the bottom outer end of the RTK centering rod. A controller and a battery, arranged vertically, are fixedly connected to the right end of the fixed base. A gear is fixedly connected to the bottom end of the RTK centering rod. A fixed shaft, rotatably connected to the fixed base, is fixedly connected to the inner side of the gear. A rack is meshed with the outer side of the gear. A slider, slidably connected to the fixed base, is fixedly connected to the outer side of the rack. A first electric push rod, fixedly connected to the fixed base, is fixedly connected to the inner side of the slider.
[0006] As a further improvement of this utility model, a wind speed sensor is provided on the right side of the top of the fixed base, and the wind speed sensor is fixedly connected to the fixed base.
[0007] As a further improvement of this utility model, cams are fixedly connected to both the front and rear ends of the outer side of the fixed shaft. The bottom of the cam contacts a piston plate that is slidably connected to the fixed seat. A spring is fixedly connected to the bottom end of the piston plate, and the other end of the spring is fixedly connected to the fixed seat. An air pipe is connected to the bottom end of the outer side of the fixed seat. The other end of the air pipe is connected to a fixed sleeve that is fixedly connected to the RTK centering rod. A rubber pad is fixedly connected to the left end of the fixed sleeve.
[0008] As a further improvement of this utility model, a positioning pin is fixedly connected to the bottom end of the fixed base, the bottom end of the positioning pin is provided with a pin head, a second electric push rod is fixedly connected to the top inner side of the positioning pin, a fixed rod that contacts the positioning pin is fixedly connected to the bottom end of the second electric push rod, a rotating rod is rotatably connected to the outside of the fixed rod through a rotating shaft, and the other end of the rotating rod is rotatably connected to a barb that penetrates the positioning pin through a rotating shaft, and the barb contacts the positioning pin.
[0009] As a further improvement of this utility model, the bottom outer side of the positioning pin is provided with an external thread, the top inner side of the pin head is provided with an internal thread, and the pin head is spirally connected to the positioning pin.
[0010] Compared with the prior art, the present invention has the following beneficial effects:
[0011] 1. A multifunctional measuring rod assembly and structure for mine surveying, comprising a wind speed sensor, gears, racks, sliders, and a first electric push rod. During mine surveying operations, when encountering strong winds, the wind speed sensor detects the external wind speed. When the detected external wind speed is high, the first electric push rod retracts, controlling the slider to engage the rack with the gears. This further causes the gears to rotate the RTK centering rod 90 degrees, automatically controlling the RTK centering rod to tilt and maintain relative stability. This prevents the RTK centering rod from tilting and damaging the RTK equipment after prolonged shaking, and also minimizes fatigue damage caused by its own shaking.
[0012] 2. A multifunctional measuring rod assembly and structure for mine surveying, comprising gears, a fixed shaft, a cam, a piston plate, an air pipe, a fixed cover, and a rubber pad, wherein during the tilting of the RTK centering rod in strong winds, the gears drive the RTK centering rod to rotate, which in turn drives the cam to rotate via the fixed shaft. At this time, the rotation of the cam pushes the piston plate to compress the spring, further forcing the gas at both ends of the inner side of the fixed seat into the fixed cover through the air pipe. This causes the rubber pad to continuously deform and expand. When the RTK centering rod rotates to the specified angle, the expanded rubber pad contacts the ground first, which can buffer the rotated device and avoid collision damage after the device rotates.
[0013] 3. A multifunctional measuring rod assembly and structure for mine surveying, comprising a positioning pin, a pin head, a second electric push rod, a fixed rod, a rotating rod, and barbs. When the device is in use, the positioning pin drives the pin head to insert into the ground, and then the second electric push rod extends to push the fixed rod. Furthermore, the rotating rod rotates to push the barbs out of the positioning pin and insert them into the ground, thus improving the stability of the device when it is positioned on the ground.

In order to better illustrate the specific embodiments of the present invention, some parts in the drawings may be omitted, enlarged or reduced, and do not represent the actual product size.

Based on the specific embodiments of the present invention, all other specific embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.
[0022] Example 1
[0023] like Figure 1-5As shown, a multifunctional measuring rod assembly and structure for mine surveying includes an RTK centering rod 1. A fixed base 2 is provided at the bottom outer side of the RTK centering rod 1. A controller 3 and a battery 4 are fixedly connected to the right end of the fixed base 2 in an up-down arrangement. A gear 6 is fixedly connected to the bottom end of the RTK centering rod 1. A fixed shaft 7, which is rotatably connected to the fixed base 2, is fixedly connected to the inner side of the gear 6. A rack 8 is meshed with the outer side of the gear 6. A slider 9, which is slidably connected to the fixed base 2, is fixedly connected to the outer side of the rack 8. A first electric push rod 10, which is fixedly connected to the fixed base 2, is fixedly connected to the inner side of the slider 9.
[0024] Example 2
[0025] like Figure 1-3 As shown, in order to solve the problem of not being able to automatically control the retraction and extension of the first electric push rod 10 according to the wind speed so that the RTK centering rod 1 can automatically tilt and return to its original position, a wind speed sensor 5 is provided on the right side of the top of the fixed base 2, and the wind speed sensor 5 is fixedly connected to the fixed base 2. By setting the wind speed sensor 5 to detect the external wind speed, the controller 3 can control the first electric push rod 10 to retract when the wind speed is high, and control the first electric push rod 10 to extend and return to its original position when the wind speed is low. This facilitates the automatic control of the retraction and extension of the first electric push rod 10 so that the RTK centering rod 1 can automatically tilt and return to its original position.
[0026] Example 3
[0027] like Figure 1-4 As shown, to address the issue of inconvenience in cushioning the device after rotation and tilting, cams 12 are fixedly connected to both the front and rear ends of the outer side of the fixed shaft 7. The bottom of the cams 12 contacts a piston plate 13 that is slidably connected to the fixed seat 2. A spring 14 is fixedly connected to the bottom end of the piston plate 13, and the other end of the spring 14 is fixedly connected to the fixed seat 2. An air pipe 15 is connected to the bottom outer side of the fixed seat 2, and the other end of the air pipe 15 is connected to a fixed sleeve 16 that is fixedly connected to the RTK centering rod 1. A rubber sleeve 16 is fixedly connected to the left end of the fixed sleeve 16. During the tilting process of the RTK centering rod 1, the gear 6 drives the RTK centering rod 1 to rotate, which in turn drives the cam 12 to rotate through the fixed shaft 7. At this time, the rotation of the cam 12 pushes the piston plate 13 to compress the spring 14, further forcing the gas at both ends of the inner side of the fixed seat 2 into the fixed cover 16 through the air pipe 15. At this time, the rubber pad 17 will continuously deform and expand, so that when the RTK centering rod 1 rotates to the specified angle, the expanded rubber pad 17 will first contact the ground, which facilitates the buffering of the device after rotation and tilting.
[0028] Example 4
[0029] like Figure 1 , Figure 2 , Figure 3 and Figure 5 As shown, to solve the problem of inconvenient stable positioning of the device, a positioning pin 11 is fixedly connected to the bottom of the fixed base 2. The bottom of the positioning pin 11 is provided with a pin head 18. A second electric push rod 19 is fixedly connected to the top of the inner side of the positioning pin 11. The bottom of the second electric push rod 19 is fixedly connected to a fixed rod 20 that contacts the positioning pin 11. A rotating rod 21 is rotatably connected to the outer side of the fixed rod 20 through a rotating shaft. The other end of the rotating rod 21 is rotatably connected to a barb 22 that penetrates the positioning pin 11 and contacts the positioning pin 11. By controlling the positioning pin 11 to drive the pin head 18 to insert into the ground, and then controlling the second electric push rod 19 to extend and push the fixed rod 20, the rotating rod 21 pushes the barb 22 out of the positioning pin 11 and inserts it into the ground during the rotation process, which facilitates stable positioning of the device.
[0030] Example 5
[0031] like Figure 5 As shown, in order to solve the problem of inconvenience in replacing the nail head 18 when it is severely worn, the bottom outer side of the positioning nail 11 is provided with an external thread, and the top inner side of the nail head 18 is provided with an internal thread. The nail head 18 and the positioning nail 11 are spirally connected. By rotating the nail head 18, the spiral connection with the positioning nail 11 is disengaged, which facilitates the replacement of the nail head 18 when it is severely worn.
[0032] In this embodiment, when using the device for mine surveying operations, the positioning pin 11 is first controlled to drive the pin head 18 into the ground. Then, the controller 3 controls the second electric push rod 19 to extend and push the fixed rod 20. At this time, the rotating rod 21 will push the barb 22 out of the positioning pin 11 and into the ground during the rotation, which can improve the stability of the device when it is positioned on the ground. After the controller 3 sets the detection range of the wind speed sensor 5, the device can be used. During the use of the device, when encountering strong winds, the wind speed sensor 5 will detect the outside wind speed. When the detected outside wind speed is large, the controller 3 will automatically control the first electric push rod 10 to retract. During this process, the slider 9 will drive the rack 8 to mesh with the gear 6. Supported by the fixed shaft 7, gear 6 drives the RTK centering rod 1 to rotate 90 degrees, thereby achieving automatic control of the RTK centering rod 1 to tilt and maintain relative stability. During the tilting process of the RTK centering rod 1 in strong winds, as gear 6 drives the RTK centering rod 1 to rotate, it also drives the cam 12 to rotate through the fixed shaft 7. At this time, the rotation of the cam 12 pushes the piston plate 13 to compress the spring 14, further forcing the gas at both ends of the inner side of the fixed seat 2 into the fixed cover 16 through the air pipe 15. At this time, the rubber pad 17 will continuously deform and expand. Thus, when the RTK centering rod 1 rotates to the specified angle, the expanded rubber pad 17 will first contact the ground, which can buffer the rotated device and avoid collision damage after the device rotates.
