Description

Technical Field

[0001] This invention relates to the field of geotechnical surveying equipment technology, and more particularly to a surveying equipment for geotechnical construction. Background Technology

[0002] In recent years, with the development of remote sensing technology, surveying devices based on remote sensing mapping technology have been widely used in the field of geotechnical construction. These devices acquire high-resolution ground images and data by carrying various remote sensing sensors and camera equipment. For example, patent CN 218272736 U discloses a geotechnical detection device for road engineering surveying. It has a surveying detector mounted on the upper side of a mounting base and rollers mounted on the lower side of the base. The rollers move the mounting base, which in turn moves the surveying detector to survey the geotechnical soil. However, this device can only move via the rollers, making its movement inflexible. Furthermore, it cannot sample the geotechnical soil, resulting in a relatively limited functionality. Summary of the Invention

[0003] In view of this, it is necessary to provide a surveying device for geotechnical construction to solve the technical problems of existing surveying devices that can only move by rollers, which is not flexible enough, and cannot sample soil and rock, and have relatively limited functions.

[0004] This invention provides a surveying device for geotechnical construction, the surveying device for geotechnical construction comprising:

The two ends of the connecting arm are a rotating end and a working end, respectively. The rotating end is rotatably connected to the surveying and mapping body, so that the connecting arm has a flight position and a driving position located on the rotation stroke.

[0006] The mobile device includes a flight mechanism and a driving mechanism disposed at the working end. The flight mechanism, when the connecting arm is in the flight position, enables the mapping subject to fly; the driving mechanism, when the connecting arm is in the driving position, enables the mapping subject to drive.

[0016] Optionally, the surveying body is provided with a slot corresponding to the mounting base, and one end of the adjusting arm connected to the stepper screw motor is connected to a limiting rod. When the stepper screw motor moves, the limiting rod can extend into and out of the slot, and when it extends into the slot, it can restrict the rotation of the drive sleeve.

[0017] Optionally, the sampling mechanism further includes a chassis, a drive gear, a clamping motor, and multiple grippers. The chassis is mounted on the mounting base and spaced apart at the bottom of the telescopic rod, and has multiple guide grooves. The drive gear has multiple drive arc-shaped grooves in the middle corresponding to the multiple guide grooves, and is rotatably mounted on the upper side of the chassis. The multiple grippers correspond one-to-one with the multiple guide grooves, and one end of each gripper extends from the guide groove into the drive arc-shaped groove. The clamping motor is mounted on the chassis, and its output shaft has an output gear.

[0018] Optionally, the support base is provided with a sliding groove corresponding to each of the two digging spoons, and each digging spoon is provided with a slider corresponding to the sliding groove, the slider being slidably disposed in the sliding groove;

[0019] The digging drive unit includes a digging motor and two connecting rods. The digging motor is located between the two digging scoops.

[0021] Compared with existing technologies, the surveying device for geotechnical construction provided by this invention integrates both the flight mechanism and the travel mechanism into the connecting arm. When the connecting arm rotates to the flight position, the flight mechanism propels the surveying main body into flight, facilitating aerial acquisition of ground images and data. Conversely, when the connecting arm rotates to the travel position, the travel mechanism moves the surveying main body across the ground, enabling close-range ground exploration. This more flexible movement method is suitable for more complex environments. Furthermore, integrating the flight and travel mechanisms into the connecting arm saves space, allowing for the installation of more surveying equipment on the surveying main body and improving surveying accuracy. Simultaneously, the inclusion of a sampling and storage mechanism on the surveying main body facilitates multiple ground samplings and storage, saving manpower and enabling analysis of soil and rock conditions through sample collection, thus enhancing the practicality of the surveying device.

[0042] Preferred embodiments of the present invention will now be described in detail with reference to the accompanying drawings, which form part of this application and are used together with the embodiments of the present invention to illustrate the principles of the present invention, but are not intended to limit the scope of the present invention.

[0043] Please see Figures 1 to 16 The surveying device 100 for geotechnical construction includes surveying equipment, mobile equipment, and sampling equipment. The surveying equipment includes a surveying body 1 and a connecting arm 2. The surveying body 1 is used to collect ground information. The two ends of the connecting arm 2 are a rotating end 21 and a working end 22, respectively. The rotating end 21 is rotatably connected to the surveying body 1, so that the connecting arm 2 has a flight position and a travel position located in the rotation stroke. The mobile equipment includes a flight mechanism 3 and a travel mechanism 4 located at the working end 22. The flight mechanism 3 can drive the surveying body 1 to fly when the connecting arm 2 is in the flight position, and the travel mechanism 4 can drive the surveying body 1 to travel when the connecting arm 2 is in the travel position. The sampling equipment includes a sampling mechanism 5 and a storage mechanism 6 located at the surveying body 1. The sampling mechanism 5 is used to obtain geotechnical samples and can be stored in the storage mechanism 6.

[0044] In the surveying device 100 for geotechnical construction provided by this invention, both the flight mechanism 3 and the travel mechanism 4 are located on the connecting arm 2. When the connecting arm 2 rotates to the flight position, the flight mechanism 3 can drive the surveying body 1 to fly, allowing the surveying body 1 to collect ground images and data in the air. When the connecting arm 2 rotates to the travel position, the travel mechanism 4 can drive the surveying body 1 to move on the ground surface, allowing the surveying body 1 to conduct close-range ground exploration. The movement method is more flexible and can be applied to more complex environments. In addition, integrating the flight mechanism 3 and the travel mechanism 4 into the connecting arm 2 saves space, allowing more surveying equipment to be installed on the surveying body 1 and improving surveying accuracy. At the same time, a sampling mechanism 5 and a storage mechanism 6 are provided on the surveying body 1, facilitating multiple samplings on the ground through the sampling mechanism 5 and storage in the storage mechanism 6, saving manpower and facilitating the analysis of geotechnical conditions through geotechnical samples, thereby improving the practicality of the surveying device.

[0045] It should be noted that in this embodiment, the mapping body 1 includes a housing 11 and a mapping mechanism 12. Multiple support arms are connected to the bottom of the housing 11, spaced apart to support the housing 11. A rotating end 21 is rotatably connected to the housing 11, and the length of the support arm is less than the length of the connecting arm 2. The mapping mechanism 12 is used to detect ground information. Thus, when the connecting arm 2 is in flight position, it can support the housing 11 via the support arms, facilitating the take-off and landing of the mapping body 1 and improving convenience. Specifically, the mapping mechanism 12 includes a camera and a detection radar. A mounting shell is also provided between the camera and the housing 11, mounted on the housing 11. The camera and the mounting shell are connected by a shaft. The camera has two orientations and can illuminate all areas in front of the housing 11. The camera has optical imaging capabilities. In addition, a detection radar and sensors are installed to quickly acquire large-area ground images and data during the flight of the mapping body 1.

[0046] Furthermore, the surveying equipment also includes a rotating shaft 7, a guide block, and a rotation drive unit. The rotating shaft 7 has an extension arm 72 arranged radially. The rotation drive unit is located on the surveying body 1 and is drivenly connected to the extension arm 72 to drive the extension arm 72 to rotate. The guide block corresponds to the rotating shaft 7, is rotatably located on the surveying body 1, and has a guide gap 71a. The rotating end 21 is sleeved on the outer periphery of the rotating shaft 7, and the connecting arm 2 is slidably disposed within the guide gap 71a, so that when the extension arm 72 rotates, it can drive the connecting arm 2 to switch between the flight position and the driving position. In this solution, when the rotation drive unit drives the extension arm 72 to rotate, it can drive the rotating shaft 7 to rotate eccentrically. The rotating end 21 of the connecting arm 2 is sleeved on the outer periphery of the rotating shaft 7, that is, the rotating end 21 can rotate relative to the rotating shaft 7, so that when the rotating shaft 7 rotates eccentrically, it can drive the connecting arm 2 to slide in the guide gap 71a of the guide block, so as to facilitate the stable switching of the connecting arm 2 between the flight position and the driving position. It should be noted that in this embodiment, the flight position is the position when the connecting arm 2 is in a horizontal state, while the travel position is the position when the connecting arm 2 is in a vertical state.

[0047] Furthermore, the flight mechanism 3 includes a flight propeller 31 located at the working end 22, and the travel mechanism 4 includes a roller 41 located at the working end 22. The roller 41 has a clearance space in its center to accommodate the flight propeller 31. In this design, the flight propeller 31 is placed within the clearance space of the roller 41 to improve space utilization. It should be noted that in this embodiment, the inner circumference of the roller 41 is provided with transmission teeth, and the mapping body 1 has a travel motor 42 corresponding to the transmission teeth. When the connecting arm 2 rotates to a vertical position, the output gear on the output shaft of the travel motor 42 meshes with the transmission teeth, thereby driving the roller 41 to rotate; when the connecting arm 2 rotates to a horizontal position, the output gear on the output shaft of the travel motor 42 disengages from the transmission teeth. In addition, in this design, four connecting arms 2, four flight propellers 31, and four rollers 41 are provided, with other structures correspondingly arranged.

[0048] Furthermore, the sampling mechanism 5 includes a mounting base 51, a telescopic structure 52, a digging drive unit 53, and two digging scoops 54. The mounting base 51 is mounted on the surveying body 1. The telescopic structure 52 is located on the mounting base 51 and is provided with a support base 521. The support base 521 can move closer to and further away from the mounting base 51. The digging drive unit 53 is located on the support base 521 and is driven to connect with the two digging scoops 54 respectively, so as to drive the two digging scoops 54 to move closer and further away from each other. In this solution, the telescopic structure 52 can drive the digging scoops 54 to extend forward and retract backward, while the digging drive unit 53 can drive the two digging scoops 54 to move closer to each other, so as to achieve the digging of soil and rock.

[0049] Furthermore, the telescopic structure 52 includes a telescopic rod 522, an adjusting screw 523, an adjusting arm 524, and a stepper screw motor 525. One end of the telescopic rod 522 is rotatably connected to the mounting base 51, and the other end is rotatably connected to the support base 521. The adjusting screw 523 corresponds to the telescopic rod 522, and one end is rotatably connected to the mounting base 51. The middle part of the adjusting arm 524 is rotatably connected to the mounting base 51, and one end is connected to the support base 521, while the other end is driven by the stepper screw motor 525. The stepper screw motor 525 is mounted on the adjusting screw 523 to drive the support base 521 to telescopically move during operation. In this way, the telescopic rod 522 can be driven to complete the telescopic movement by the movement of the stepper screw motor 525, thereby driving the scoop 54 to move forward. The structure is simple and reliable.

[0050] Specifically, in this design, the support base 521 is provided with a groove 521a corresponding to each of the two digging scoops 54, and each digging scoop 54 is provided with a slider corresponding to the groove 521a, with the slider slidingly disposed in the groove 521a; the digging drive unit 53 includes a digging motor 531 and two connecting rods 532, the digging motor 531 being disposed between the two digging scoops 54, one end of each connecting rod being rotatably connected to the corresponding digging scoop 54, and the other end being drivenly connected to the digging motor 531, so that when the digging motor 531 moves, it drives the two digging scoops 54 to move closer or further apart. In this embodiment, the digging motor 531 drives the two connecting rods 532 to rotate, thereby driving the two digging scoops 54 to move closer or further apart along the extension direction of the groove 521a, so as to realize the rock and soil digging and storage operation.

[0051] Furthermore, the mounting base 51 is provided with a drive sleeve 511, which has a drive screw hole and a guide rod 512 extending radially. The surveying body 1 is provided with a limiting groove 1b corresponding to the guide rod 512, and a guide ring 8 is provided at intervals at its bottom. The guide ring 8 has an annular groove 8a, which has a notch to connect with the limiting groove 1b. The surveying equipment also includes a drive motor and a rotating lead screw 9. The rotating lead screw 9 extends into the drive screw hole. The drive motor is located on the surveying body 1 and is driven and connected to the rotating lead screw 9 to drive the rotating lead screw 9 to rotate, so that the guide rod 512 can switch between the limiting groove 1b and the annular groove 8a. In this solution, when the drive motor drives the rotating lead screw 9 to rotate initially, a section of the guide rod 512 away from the drive sleeve 511 is slidably inserted into the limiting groove 1b. In this embodiment, the limiting groove 1b extends vertically, so that the mounting base 51 can rise and fall vertically when the rotating lead screw 9 rotates. When the lead screw 9 rotates, causing the guide rod 512 to slide from the limiting groove 1b into the annular groove 8a of the guide ring 8, the mounting base 51 rotates under the drive of the lead screw 9. At this time, it is convenient for the excavator 54 to transport the soil and rock to the storage mechanism 6 on the side, ensuring the rationality of the position setting of each mechanism. It should be noted that the guide ring 8 is fixed to the housing 11.

[0052] Furthermore, the surveying body 1 is provided with a slot 1a corresponding to the mounting base 51. One end of the adjusting arm 524 connected to the stepper screw motor 525 is connected to a limiting rod 526. When the stepper screw motor 525 moves, the limiting rod 526 can extend into and disengage from the slot 1a, and when it extends into the slot 1a, it can restrict the rotation of the drive sleeve 511. Thus, when it is necessary to raise the mounting base 51, the stepper screw motor 525 can be moved to drive the limiting rod 526 into the slot 1a, thereby facilitating the guide rod 512 to enter the limiting groove 1b from the notch in the annular groove 8a, thereby raising the mounting base 51.

[0053] Furthermore, the sampling mechanism 5 also includes a chassis 55, a drive gear 56, a clamping motor 57, and multiple grippers 58. The chassis 55 is mounted on the mounting base 51 and spaced at the bottom of the telescopic rod 522, and has multiple guide grooves 55a. The drive gear 56 has multiple drive arc-shaped grooves 56a corresponding to the multiple guide grooves 55a in its middle part, and is rotatably mounted on the upper side of the chassis 55. The multiple grippers 58 correspond one-to-one with the multiple guide grooves 55a, and one end of each gripper 58 extends from the guide groove 55a into the drive arc-shaped groove 56a. The clamping motor 57 is mounted on the chassis 55, and its output shaft has an output gear. The output gear meshes with the drive gear 56 to drive the drive gear 56 to rotate, so that the multiple grippers 58 can move closer or further apart. In this embodiment, the clamping motor 57 can drive the drive gear 56 to rotate, thereby driving the multiple grippers 58 to move closer or further apart, so as to realize the clamping and releasing actions.

[0054] Specifically, in this design, the bottom of the gripper 58 is provided with a push tube 59, which extends radially along the gripper 58, and the push tubes 59 are arranged close to each other. In addition, the push tubes 59 are connected to the corresponding grippers 58 by an elastic element, so that the push tubes 59 can elastically extend and retract relative to the grippers 58 to facilitate the gripping of irregularly shaped objects.

[0055] Furthermore, the storage mechanism 6 includes a first rack 61, a motor support 62, a lifting motor 63, an adjusting motor 64, a tray 65, a slide rail 66, and a storage box 67. The first rack 61 is located on the surveying body 1 and extends vertically. The motor support 62 corresponds to the first rack 61. The lifting motor 63 is located on the motor support 62, and its output shaft is provided with a first gear. The first gear meshes with the first rack 61 to drive the motor support 62 to rise and fall when rotating. The slide rail 66 is slidably located on the motor support 62 in the horizontal direction and connected to the tray 65. It is also provided with a second rack 68. The adjusting motor 64 is located on the motor support 62 and corresponds to the second rack 68. Its output shaft is provided with a second gear. The second gear meshes with the second rack 68 to drive the slide rail 66 to move when rotating. The storage box 67 is located on the tray 65. In this embodiment, the storage box 67 can be raised and lowered by the cooperation of the lifting motor 63 and the first rack 61. At the same time, the storage box 67 can be moved horizontally by adjusting the cooperation of the motor 64 and the slide rail 66, making the position adjustment between the storage box 67 and the sampling mechanism 5 more flexible.

[0056] Furthermore, in this embodiment, the storage box 67 and the tray 65 can be magnetically connected via a magnetic component to improve the stability of the storage box 67. Additionally, a baffle 69 is provided on the housing 11 corresponding to the storage box 67, so that when the slide rail 66 slides, the baffle 69 can drive the storage box 67 to slide off the tray 65, facilitating sample unloading.

[0057] The above description is only a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any changes or substitutions that can be easily conceived by those skilled in the art within the scope of the technology disclosed in the present invention should be included within the scope of protection of the present invention.
