Description

Technical Field

[0001] This invention relates to the field of surveying tools technology, and to a fixed auxiliary device, particularly a fixed auxiliary device for remote sensing by a surveying and mapping engineering drone. Background Technology

[0002] In the process of collecting and mapping some spatial information, drones are needed. They are unmanned aircraft controlled by radio remote control equipment and self-contained program control devices, or operated autonomously by on-board computers, either completely or intermittently. Among them, the remote sensor is one of the main components, and its main function is to detect electromagnetic waves radiated or reflected by ground objects and the environment from a distance.

[0003] Currently, most remote sensors on drones are installed at the bottom. When installing these sensors, multiple bolts are needed for fixation, requiring workers to hold the sensor with one hand and use the other to secure it with installation tools. This makes it inconvenient for workers to adjust the installation angle of the drone during assembly, hindering the sensor fixation process. Furthermore, the bolts used to secure the sensors are often quite small, making it difficult for workers to locate fallen bolts on the assembly table, thus reducing the efficiency of sensor fixation. Summary of the Invention

[0004] The purpose of this invention is to address the aforementioned problems in existing technologies by proposing a fixing auxiliary device for remote sensing of surveying and mapping engineering UAVs. This fixing auxiliary device for remote sensing of surveying and mapping engineering UAVs has an auxiliary fixing function, allowing operators to adjust the fixing angle of the UAV according to the assembly situation, assisting operators in quickly completing the fixing operation of the remote sensor. Moreover, the device can also collect accidentally dropped parts during the fixing process, making it convenient for operators to quickly find the corresponding parts for subsequent assembly work.

[0005] The objective of this invention can be achieved through the following technical solutions:

[0006] A fixed auxiliary device for remote sensing of a UAV in surveying engineering includes a mounting platform, a base below the mounting platform, a rotating structure internally connected to the base, base plates fixed to the bottom of both sides of the base, an adjustment structure fixed above the base plates, a groove on the surface of the mounting platform, adjustment plates on both sides of the mounting platform with one side extending into the groove and slidingly connected to the inner wall of the groove, mounting boxes fixed to the top of the mounting platform with a linkage structure inside the mounting boxes, first threaded rods penetrating the front and rear sides of the top of the mounting boxes and rotatably connected to the mounting boxes, a lifting sleeve sleeved on the surface above the first threaded rods and threadedly connected to the inner wall of the lifting sleeve, a placement frame fixed to the top of the lifting sleeve and the UAV placed on the placement frame, a fixing frame fixed to the middle of the top of the mounting platform with a lifting structure internally connected to the fixing frame, a receiving platform above the fixing frame and an electromagnet embedded in the surface of the receiving platform.

[0007] The working principle of this invention is as follows: When the operator needs to install the remote sensor of a drone below the drone, the drone is first placed on the mounting rack, and the height of the drone is adjusted according to its size. After adjustment, the height of the receiving platform is moved so that it is close to the bottom of the drone. Then, the operator can continue the fixing operation of the remote sensor. During the fixing process, the first motor can be turned on to rotate and adjust the assembly angle. The electric push rods on both sides can also be turned on to tilt the mounting platform, further adjusting the fixing angle of the drone for the operator to fix. During the fixing process, the receiving platform below can attract any fallen bolts for easy retrieval. After the remote sensor is assembled, the operator can pull the drone upwards to remove it, thus completing the fixing operation of the drone remote sensor.

[0008] The rotating structure includes a rotating rod, a first motor, a first bevel gear, and a second bevel gear. The rotating rod is rotatably connected to the bottom of the inner wall of the base, and the top end of the rotating rod extends through to the bottom of the mounting platform and is hinged to the bottom of the mounting platform via a universal joint. The first motor is fixed to the right side of the inner wall of the base, the first bevel gear is fixed to the left end of the output shaft of the first motor, and the second bevel gear is fixed to the bottom of the surface of the rotating rod, and the first bevel gear and the second bevel gear mesh with each other.

[0009] The above structure allows the mounting platform to rotate, thus adjusting the fixed angle.

[0010] The adjustment structure includes an electric push rod, a fixed groove, and a rotating shaft. The electric push rod is fixed to one side of the top of the base plate. The fixed groove is opened on the surface of the adjustment plate, and the top end of the output shaft of the electric push rod passes through the fixed groove. The rotating shaft is set on the front and rear sides of the inner wall of the fixed groove, and one end of the rotating shaft is fixedly connected to the output shaft of the electric push rod.

[0011] The above structure allows the mounting platform to tilt to one side for easy fixing.

[0012] Positioning grooves are provided on both the front and rear sides of the inner wall of the fixed groove. A positioning block is slidably connected to one side of the inner wall of the positioning groove, and one end of the rotating shaft is rotatably connected to the positioning block.

[0013] With the above structure, when the output shaft of the electric actuator moves, it is convenient to drive the adjustment plate to move and adjust the tilt angle of the mounting platform.

[0014] Limiting grooves are provided on both the upper and lower sides of the inner wall of the groove. Limiting blocks are fixed on one side of the upper and lower sides of the adjusting plate, and one side of the limiting block extends into the interior of the limiting groove and slides in connection with the inner wall of the limiting groove.

[0015] The above structure is used to limit the adjustment plate and prevent it from moving out of the groove.

[0016] The linkage structure includes a housing, a second motor, a double-groove pulley, and a single-groove pulley. The housing is fixed to the center of the top of the mounting box. The second motor is fixed inside the housing, and its output shaft extends through the interior of the mounting box. The double-groove pulley is rotatably connected to the center of the interior of the mounting box, and the bottom end of the second motor's output shaft is fixedly connected to the double-groove pulley. The single-groove pulley is rotatably connected to the front and rear sides of the interior of the mounting box, and it is connected to the double-groove pulley via a belt. The bottom end of the first threaded rod is fixedly connected to the top of the single-groove pulley.

[0017] The above structure allows the first threaded rods on both the front and rear sides to rotate synchronously, thereby lifting the drone.

[0018] A limiting rod is fixed to the surface of the top of the box, and a limiting plate is provided above the box. The front and rear sides of the limiting plate are fixedly connected to the lifting sleeve. The limiting rod passes through the limiting plate and is slidably connected to the limiting plate.

[0019] The above structure limits the movement of the lifting sleeve, allowing it to move only up and down.

[0020] The lifting structure includes a third threaded rod, a threaded sleeve, a knob, and a support rod. The third threaded rod is rotatably connected inside the fixed frame, and the front and rear threads on the surface of the third threaded rod are arranged in opposite directions. There are two threaded sleeves, which are threadedly connected to the front and rear sides of the surface of the third threaded rod. The knob is rotatably connected to the front side of the fixed frame, and the rear end of the knob passes through the fixed frame and is fixedly connected to the front end of the third threaded rod. The support rod is hinged above the threaded sleeve, and the top end of the support rod is hinged to the bottom of the receiving platform. The support rod is inclined as a whole.

[0021] The above structure allows for adjustment of the vertical height of the receiving platform to catch any fallen bolts.

[0022] The bottom of the inner wall of the fixed frame is provided with a guide groove, the bottom of the threaded sleeve is fixed with a guide rod, and the bottom end of the guide rod extends into the interior of the guide groove and is bolted with a guide block. The guide block is slidably connected to the inner wall of the guide groove.

[0023] The above structure can guide the threaded sleeve, allowing it to move only back and forth.

[0024] The placement rack is U-shaped, and anti-slip pads are glued to both sides of the inner wall of the placement rack. The anti-slip pads are made of rubber.

[0025] The above structure enhances the stability of the drone by increasing the mounting bracket, making it easier for staff to fix the remote sensor.

[0026] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0027] 1. This invention has an auxiliary fixing function. During the fixing process of the drone remote sensor, the operator can adjust the fixing angle of the drone according to the assembly situation, which helps the operator to quickly complete the fixing operation of the remote sensor. Moreover, the device can also collect accidentally dropped parts during the fixing process, so that the operator can quickly find the corresponding parts for subsequent assembly work, which improves the fixing efficiency. The device can also adjust the fixing height according to the size of the drone being fixed, which increases the practicality of the device.

[0028] 2. By using electric push rods, fixing slots, and rotating shafts, this invention allows workers to open the electric push rods on both sides during the assembly of the drone's remote sensor. This causes the output shaft of one electric push rod to move upward and the output shaft of the other electric push rod to move downward, thereby tilting the entire mounting platform and adjusting the assembly angle. This facilitates the installation of the drone's remote sensor by the workers.

[0029] 3. This invention, through the arrangement of the housing, the second motor, the double-groove pulley, and the single-groove pulley, allows the second motor on both sides to be turned on after the operator places the drone to be installed on the mounting frame. This causes the output shaft of the second motor to drive the double-groove pulley below to rotate, and the belt causes the single-groove pulleys on both sides to rotate synchronously. The first threaded rods on both sides rotate, causing the lifting sleeve to push the mounting frame upward, thereby adjusting the installation height of the drone and facilitating the subsequent drone remote sensor assembly operation.

During the fixing of the drone remote sensor, the operator can adjust the fixing angle of the drone according to the assembly situation, which helps the operator to quickly complete the fixing operation of the remote sensor. Moreover, the device can also collect accidentally dropped parts during the fixing process, making it convenient for the operator to quickly find the corresponding parts for subsequent assembly work, thus improving the fixing efficiency. The device can also adjust the fixing height according to the size of the drone being fixed, increasing the practicality of the device.

[0040] The rotating structure 3 includes a rotating rod 31, a first motor 32, a first bevel gear 33, and a second bevel gear 34. The rotating rod 31 is rotatably connected to the bottom of the inner wall of the base 2, and the top of the rotating rod 31 extends through to the bottom of the mounting platform 1 and is hinged to the bottom of the mounting platform 1 via a universal joint. The first motor 32 is fixed to the right side of the inner wall of the base 2, the first bevel gear 33 is fixed to the left end of the output shaft of the first motor 32, and the second bevel gear 34 is fixed to the bottom of the surface of the rotating rod 31, and the first bevel gear 33 and the second bevel gear 34 mesh with each other. With the arrangement of the rotating rod 31, the first motor 32, the first bevel gear 33, and the second bevel gear 34, when assembling the remote sensor of the UAV, the operator can open the first motor 32 below, so that the output shaft of the first motor 32 drives the first bevel gear 33 to rotate. Since the first bevel gear 33 and the second bevel gear 34 mesh, the rotating rod 31 drives the mounting platform 1 above to rotate, thereby adjusting the mounting angle for the operator to assemble.

[0041] The adjustment structure 5 includes an electric push rod 51, a fixing groove 52, and a rotating shaft 53. The electric push rod 51 is fixed to one side of the top of the base plate 4. The fixing groove 52 is opened on the surface of the adjustment plate 6, and the top end of the output shaft of the electric push rod 51 passes through the fixing groove 52. The rotating shaft 53 is set on the front and rear sides of the inner wall of the fixing groove 52, and one end of the rotating shaft 53 is fixedly connected to the output shaft of the electric push rod 51. With the arrangement of the electric push rod 51, the fixing groove 52, and the rotating shaft 53, when assembling the remote sensor of the UAV, the staff can open the electric push rods 51 on both sides, so that the output shaft of one side of the electric push rod 51 moves up and the output shaft of the other side of the electric push rod 51 moves down, thereby causing the entire mounting platform 1 to tilt, adjusting the assembly angle, and facilitating the staff to install the remote sensor of the UAV.

[0042] Positioning grooves 19 are provided on both the front and rear sides of the inner wall of the fixing groove 52. A positioning block 20 is slidably connected to one side of the inner wall of the positioning groove 19. One end of the rotating shaft 53 is rotatably connected to the positioning block 20. Through the setting of the positioning groove 19 and the positioning block 20, the positioning blocks 20 on both sides can position the electric push rod 51, so that the electric push rod 51 can adjust the entire mounting platform 1 when it moves up and down. In addition, during the adjustment of the tilt of the mounting platform 1, the positioning block 20 will also slide inside the positioning groove 19.

[0043] Limiting grooves 17 are provided on both the upper and lower sides of the inner wall of the groove 7. Limiting blocks 18 are fixed on one side of the upper and lower sides of the adjusting plate 6. One side of the limiting block 18 extends into the interior of the limiting groove 17 and slides in connection with the inner wall of the limiting groove 17. By setting the limiting groove 17 and the limiting block 18, the connection between the adjusting plate 6 and the mounting platform 1 is increased when the mounting platform 1 is rotated and adjusted, so as to prevent the mounting platform 1 and the adjusting plate 6 from separating during the adjustment process.

[0044] The linkage structure 9 includes a housing 91, a second motor 92, a double-groove pulley 93, and a single-groove pulley 94. The housing 91 is fixed to the middle of the top of the mounting box 8. The second motor 92 is fixed inside the housing 91, and the output shaft of the second motor 92 extends through the interior of the mounting box 8. The double-groove pulley 93 is rotatably connected to the middle of the interior of the mounting box 8, and the bottom end of the output shaft of the second motor 92 is fixedly connected to the double-groove pulley 93. The single-groove pulley 94 is rotatably connected to the front and rear sides of the interior of the mounting box 8, and the single-groove pulley 94 is connected to the double-groove pulley 93 via a belt. The bottom end of the first threaded rod 10 is connected to the single-groove pulley 94. The top of the pulley 94 is fixedly connected. Through the arrangement of the box 91, the second motor 92, the double-groove pulley 93 and the single-groove pulley 94, when the staff places the drone to be installed on the placement rack 12, the second motors 92 on both sides can be turned on, so that the output shaft of the second motor 92 drives the double-groove pulley 93 below to rotate. Through the belt, the single-groove pulleys 94 on the front and rear sides rotate synchronously, and the first threaded rods 10 on both sides rotate, so that the lifting sleeve 11 pushes the placement rack 12 to rise, thereby adjusting the installation height of the drone and facilitating the staff to carry out subsequent drone remote sensor assembly operations.

[0045] A limiting rod 22 is fixed to the top surface of the box 91. A limiting plate 21 is provided above the box 91, and the front and rear sides of the limiting plate 21 are fixedly connected to the lifting sleeve 11. The limiting rod 22 passes through the limiting plate 21 and is slidably connected to the limiting plate 21. With the setting of the limiting plate 21 and the limiting rod 22, when the first threaded rod 10 rotates, the limiting plate 21 can limit the lifting sleeve 11, so that the lifting sleeve 11 will not rotate with the rotation of the first threaded rod 10. The lifting sleeve 11 can support the placement frame 12 to move up and down to adjust the height of the drone.

[0046] The lifting structure 14 includes a third threaded rod 141, a threaded sleeve 142, a knob 143, and a support rod 144. The third threaded rod 141 is rotatably connected inside the fixed frame 13, and the front and rear threads on the surface of the third threaded rod 141 are arranged in opposite directions. There are two threaded sleeves 142, which are threadedly connected to the front and rear sides of the surface of the third threaded rod 141. The knob 143 is rotatably connected to the front side of the fixed frame 13, and the rear end of the knob 143 passes through the fixed frame 13 and is fixedly connected to the front end of the third threaded rod 141. The support rod 144 is hinged above the threaded sleeve 142, and the support rod... The top of the support rod 144 is hinged to the bottom of the receiving platform 15. The support rod 144 is inclined. With the setting of the third threaded rod 141, threaded sleeve 142, knob 143 and support rod 144, after the staff adjusts the height of the drone, they can turn the knob 143, which will cause the third threaded rod 141 to rotate. The threaded sleeves 142 on both sides will move towards each other, and the support rod 144 will move, pushing the receiving platform 15 to rise. Then, according to the assembly height of the drone, the height of the receiving platform 15 can be adjusted to catch parts that fall during the assembly of the remote sensor.

[0047] A guide groove 24 is provided at the bottom of the inner wall of the fixed frame 13. A guide rod 25 is fixed at the bottom of the threaded sleeve 142, and the bottom end of the guide rod 25 extends into the interior of the guide groove 24 and is bolted with a guide block 26. The guide block 26 is slidably connected to the inner wall of the guide groove 24. Through the setting of the guide groove 24, the guide rod 25 and the guide block 26, the threaded sleeve 142 above is guided during the rotation of the third threaded rod 141. Initially, the threaded sleeve 142 can only move horizontally in the back and forth direction, thereby adjusting the height of the receiving platform 15.

[0048] The placement rack 12 is U-shaped, and anti-slip pads 23 are glued to both sides of the inner wall of the placement rack 12. The anti-slip pads 23 are made of rubber. With the anti-slip pads 23, when the staff places the drone on the placement rack 12, the anti-slip pads 23 on both sides can fit against the surface of the drone, thereby simply fixing the drone in place for subsequent assembly of the remote sensor.

[0049] The working principle of this invention is as follows: When a worker needs to install the remote sensor of a drone below the drone, the worker first places the drone to be installed on the placement rack 12 and fixes the drone with the four placement racks 12. After fixing, the worker can turn on the second motors 92 on both sides, causing the lifting sleeve 11 to push the placement rack 12 up and down. According to the size of the drone, the assembly height of the drone is adjusted. After adjustment, the worker turns the knob 143, which causes the support rod 144 to push the receiving platform 15 up, so that the receiving platform 15 is close to the drone. After adjusting the height of the receiving platform 15, the worker can take out the remote sensor and use tools to assemble the remote sensor. During the assembly process, the worker... The operator can open the first motor 32 below, causing the entire mounting platform 1 to rotate, thereby adjusting the assembly angle. They can also open the electric push rods 51 on both sides, causing the entire mounting platform 1 to tilt to one side, further adjusting the assembly angle to assist the operator in installing the remote sensor. During the assembly process, if the assembly bolts fall off, the receiving platform 15 below will catch the bolts. The bolts are attracted by the electromagnet 16, so that they can be easily fixed inside the receiving platform 15, making it convenient for the operator to continue to retrieve and use them. After the remote sensor is fixed under the drone, the operator can pull the drone upwards to remove it, thus completing the fixing operation of the drone remote sensor.
