The outer cylinder has a channel with an opening at its lower end, and the upper end of the outer cylinder is used for mounting a surveying instrument. The inner cylinder is vertically movably installed within the channel. The drill bit is rotatably installed at the lower end of the inner cylinder along its vertical axis. The drive assembly is located in the inner cylinder and connected to the drill bit, driving the drill bit to rotate. The linkage assembly connects the drill bit and the inner cylinder, converting the rotation of the drill bit into vertical movement of the inner cylinder, so that when the drive assembly drives the drill bit to rotate, the linkage assembly drives the inner cylinder to move vertically.

Description

Technical Field

[0001] This invention relates to the field of surveying equipment technology, and in particular to a surveying and positioning device for slope engineering. Background Technology

[0002] Slope engineering refers to the modification of natural and artificial slopes to meet engineering needs. It is an outdoor construction project. Slope engineering can be categorized into different types based on various influencing factors. For example, based on the time difference of the slope's impact on the project, it can be divided into permanent slopes and temporary slopes. Based on the relationship between the slope and the project, it can be divided into foundation slopes, adjacent slopes, and extended slopes with minimal impact on the building. When constructing and modifying slope engineering projects, surveying and positioning are necessary to facilitate the design and construction of the slope engineering scheme.

[0003] Patent CN115585350A describes a leveling bracket for a land surveying instrument. When fixing the bracket on the ground, a second telescopic component extends and retracts the spike cone to drive it into the ground. The angle at which the spike cone drives into the ground is adjusted according to the pointer of the pointer angle meter. The four first screws connected to the bottom and the fixing block are rotated to move the fixing block downwards, so that the anti-slip block contacts the ground and the bracket is stably fixed on the ground.

[0004] The aforementioned prior art uses a second telescopic component to extend and retract the spike cone to drive it into the ground. However, when facing hard ground, the elasticity of the second telescopic component alone is insufficient to drive the spike cone into the ground, making it difficult to drive it in. Summary of the Invention

[0005] In view of this, it is necessary to provide a surveying and positioning device for slope engineering to solve the technical problem that in the prior art, the spike cone is driven into the ground by extending and retracting the second telescopic component.

Detailed Implementation

[0039] 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.

[0040] Please see Figures 1 to 9The surveying and positioning device used in this slope engineering project includes an outer cylinder 1, an inner cylinder 2, a drill bit 3, a drive assembly 4, and a linkage assembly 5. The outer cylinder 1 has a channel 11 with an opening at the lower end, and the upper end of the outer cylinder 1 is used for mounting a surveying instrument. The inner cylinder 2 is movably installed in the channel 11 along the vertical direction. The drill bit 3 is rotatably installed at the lower end of the inner cylinder 2 along the vertical axis. The drive assembly 4 is located in the inner cylinder 2 and connected to the drill bit 3, and the drive assembly 4 drives the drill bit 3 to rotate. The linkage assembly 5 connects the drill bit 3 and the inner cylinder 2. The linkage assembly 5 is used to convert the rotation of the drill bit 3 into the vertical movement of the inner cylinder 2, so that when the drive assembly 4 drives the drill bit 3 to rotate, the linkage assembly 5 drives the inner cylinder 2 to move in the vertical direction.

[0041] The present invention provides a surveying and positioning device for slope engineering. The outer cylinder 1 has a channel 11 with an opening at the lower end. The inner cylinder 2 is movably installed in the channel 11 in the vertical direction. The drill bit 3 is rotatably installed at the lower end of the inner cylinder 2 along the vertical axis. The linkage component 5 connects the drill bit 3 and the inner cylinder 2. The linkage component 5 is used to convert the rotation of the drill bit 3 into the vertical movement of the inner cylinder 2. By connecting the drill bit 3 and the inner cylinder 2 through the linkage component 5, the driving component 4 can drive the drill bit 3 and the inner cylinder 2 simultaneously. Since the drill bit 3 is set on the inner cylinder 2, the drill bit 3 can move in the vertical direction under the drive of the inner cylinder 2 and can also rotate in the direction of its own axis. In this way, the drill bit 3 penetrates the ground with a rotating and downward movement trend, with strong drilling performance, and can successfully penetrate the ground when facing hard ground.

[0042] Furthermore, in this embodiment, the drive assembly 4 includes a connecting shaft 41 and a motor 42. The motor 42 is disposed in the internal space of the inner cylinder 2 and located at the top of the internal space of the inner cylinder 2. The main shaft of the motor 42 extends downward. The upper end of the connecting shaft 41 is connected to the main shaft of the motor 42, and the lower end of the connecting shaft 41 is connected to the upper end of the drill bit 3, so that the connecting shaft 41 is driven by the motor 42 to drive the drill bit 3 to rotate. The linkage assembly 5 is connected to the connecting shaft 41.

[0043] Further, in this embodiment, the linkage component 5 includes a driving bevel gear 51, a driven bevel gear 52, a rack 53, and a first gear 54. The driving bevel gear 51 is fixedly installed on the outer periphery of the drill bit 3. The driven bevel gear 52 is rotatably installed on the inner cylinder 2 along a horizontal axis. The driving bevel gear 51 meshes with the driven bevel gear 52. The first gear 54 is rotatably installed on the inner cylinder 2 along a horizontal axis, and the driven bevel gear 52 is connected to the first gear 54 through an intermediate gear set. The rack 53 is fixedly installed on the side wall of the channel 11, and the first gear 54 meshes with the rack 53. Specifically, the intermediate gear set includes a second gear 55 and a third gear 56, and the linkage assembly 5 further includes a first rotating shaft 57 and a second rotating shaft 58. The driving bevel gear 51 is fixedly installed on the outer periphery of the connecting shaft 41. The first rotating shaft 57 and the second rotating shaft 58 are both rotatably installed on the cylinder wall of the inner cylinder 2 along a horizontal axis. The first rotating shaft 57 is located inside the inner cylinder 2, and the two ends of the second rotating shaft 58 are located on the inner and outer sides of the inner cylinder 2, respectively. The driven bevel gear 52 and the second gear 55 are both fixedly installed on the first rotating shaft 57 and along the circumference of the first rotating shaft 57. The gears are arranged at intervals in the direction. The third gear 56 is fixedly installed on one end of the inner side of the second rotating shaft 58, and the first gear 54 is fixedly installed on one end of the outer side of the second rotating shaft 58. The second gear 55 and the third gear 56 mesh. In specific use, the rotation of the connecting shaft 41 drives the driving bevel gear 51 to rotate. The driving bevel gear 51 meshes with the driven bevel gear 52, which drives the second gear 55 to mesh with the third gear 56. The third gear 56 drives the first gear 54 to mesh with the rack 53, thereby converting the rotation of the connecting shaft 41 into the vertical movement of the inner cylinder 2.

[0044] Furthermore, in this embodiment, the slope engineering surveying and positioning device also includes multiple support leg assemblies 6. These supports are spaced apart circumferentially along the outer cylinder 1, and each support leg assembly 6 is movably positioned vertically. Each support leg assembly 6 is provided with a connecting portion 611. The outer periphery of the inner cylinder 2 is also provided with multiple mating portions 22, each corresponding one-to-one with a connecting portion 611. When the inner cylinder 2 moves vertically downwards, the mating portions 22 connect with the connecting portions 611 to drive the support leg assembly 6 to move vertically downwards. This arrangement allows the multiple support leg assemblies 6 to provide auxiliary support for the outer cylinder 1, improving the stability of the entire device. Furthermore, the movement of the support leg assemblies 6 under the drive of the inner cylinder 2 reduces the number of actuators and lowers costs.

[0045] Further, in this embodiment, the support assembly 6 includes a mounting rod 61, a telescopic rod 62, a ball joint support 64, and a second elastic element 65. The mounting rod 61 is slidably mounted on the outer periphery of the outer cylinder 1 in a vertical direction. The connecting part 611 is provided on the mounting rod 61. The telescopic rod 62 is elastically telescopically mounted on the lower end of the mounting rod 61 in a vertical direction via a first elastic element 63. The ball joint support 64 is mounted on the lower end of the telescopic rod 62. The two ends of the second elastic element 65 are respectively connected to the mounting rod 61 and the outer cylinder 1. The second elastic element 65 is used to drive the mounting rod 61 to move vertically upward. The first elastic element 63 is used to reset the telescopic rod 62, and the second elastic element 65 is used to reset the mounting rod 61. By setting the telescopic rod 62 and the ball joint support 64, the multiple support assemblies 6 can adapt to the sloping terrain, achieving a better effect of fixing the entire device.

[0046] It should be noted that the ball joint support 64 is existing technology and will not be described in detail here.

[0047] Furthermore, in this embodiment, the outer cylinder 1 is provided with a plurality of sliding grooves 12 communicating with the channel 11, and the plurality of sliding grooves 12 correspond one-to-one with the plurality of mating parts 22, the mating parts 22 extending into the corresponding sliding grooves 12; the upper end of the mounting rod 61 is provided with a connecting part 611, the connecting part 611 extending into the corresponding sliding groove 12, the mating parts 22 and the connecting parts 611 are arranged from top to bottom, so that when the inner cylinder 2 moves downward, the mating parts 22 abut against the connecting parts 611 to drive the mounting rod 61 to move vertically downward. The mating part 22 and the connecting part 611 are located in the same groove 12. Therefore, when the inner cylinder 2 drives the mating part 22 to move vertically downward, the mating part 22 abuts against the connecting part 611 and pushes the connecting part 611 to move vertically downward, thereby achieving the effect of driving the entire support leg assembly 6 to move downward. When the inner cylinder 2 moves vertically upward, the mating part 22 and the connecting part 611 disengage, and the mounting rod 61 returns to its initial position upward under the elastic force of the second elastic member 65.

[0048] Furthermore, since it is installed on a slope, to avoid affecting the surveying instrument, in this embodiment, the slope engineering surveying and positioning device further includes an installation component 7. The installation component 7 includes a first mounting base 71, a first driving mechanism 72, a second mounting base 73, and a second driving mechanism 74. The first mounting base 71 is rotatably mounted on the upper end of the outer cylinder 1 along a vertical axis. The first driving mechanism 72 is located on the outer cylinder 1 and connected to the first mounting base 71 to drive the first mounting base 71 to rotate. The middle part of the second mounting base 73 is rotatably mounted on the upper side of the first mounting base 71 along a horizontal axis. The second mounting base 73 is used for mounting the surveying instrument. The second driving mechanism 74 is located on the first mounting base 71 and connected to the second mounting base 73 to drive the second mounting base 73 to rotate. This configuration allows the surveying instrument to rotate in both the vertical and horizontal directions, enabling real-time adjustment of the surveying instrument's angle and direction without requiring multiple position changes, thus improving surveying efficiency.

[0049] Furthermore, the first drive mechanism 72 includes a drive gear 721, a driven gear 722, and a first drive motor 723. The first drive motor 723 is disposed on the connecting plate 754. The drive gear 721 is fixedly connected to the main shaft of the first drive motor 723. The driven gear 722 is fixedly connected to the first connecting seat. The drive gear 721 meshes with the driven gear 722.

[0050] Furthermore, the second drive mechanism 74 includes a cylinder, the cylinder body of which is rotatably mounted on the first mounting base 71, and the cylinder push rod of which is rotatably mounted on the second mounting base 73, so as to drive the second mounting base 73 to rotate through the cylinder.

[0051] Furthermore, in order to fix the surveying instrument, in this embodiment, a mounting position is provided in the middle of the upper side of the second mounting base 73, which is used for installing the surveying instrument; the slope engineering surveying and positioning device also includes a fixing component 8, which includes a plurality of clamping plates 81 and a third driving mechanism 82. The plurality of clamping plates 81 are arranged at intervals along the circumference of the mounting position. Each clamping plate 81 is movably disposed on the second mounting base 73 in the direction of approaching and moving away from the mounting position, so that when the clamping plate 81 is close to the mounting position, the plurality of clamping plates 81 are used to clamp the surveying instrument. The third driving mechanism 82 is connected to the plurality of clamping plates 81 and is used to drive the plurality of clamping plates 81 to move synchronously.

[0052] Further, the third driving mechanism 82 includes a driving disk 821, multiple connecting members 822, and a third driving motor 823. The driving disk 821 is movably mounted on the second mounting base 73 in a vertical direction. Each of the multiple connecting members 822 corresponds one-to-one with a multiple clamping plates 81. The two ends of each connecting member 822 are rotatably connected to the driving disk 821 and the clamping plate 81 along a vertical axis, respectively. The third driving motor 823 is connected to the driving disk 821 to drive its rotation. Specifically, the connecting member 822 is connected to the edge of the driving disk 821, while the main shaft of the third driving motor 823 is connected to the center of the driving disk 821. Thus, when the driving disk 821 is rotated, the clamping plates 81 can be moved via the connecting members 822.

[0053] Furthermore, the upper end of the inner cylinder 2 is provided with a locking hole 21, and the lower side of the first mounting base 71 is provided with a locking member 711. The first mounting base 71 is movably arranged in the vertical direction so as to have a locked state in which it moves downward to the locking member 711 extending into the locking hole 21 and an unlocked state in which it moves upward to the locking member 711 exiting the locking hole 21. The mounting assembly 7 also includes a fourth driving mechanism 75, which is connected to the first mounting base 71 and is used to drive the first mounting base 71 to switch between the locked state and the unlocked state.

[0054] Furthermore, the fourth driving mechanism 75 includes a rotating plate 751, a pull rod 752, and a third elastic element 753. The middle part of the rotating plate 751 is rotatably mounted above the outer cylinder 1 along the horizontal axis and is located below the first mounting seat 71. The upper end of the pull rod 752 is rotatably connected to one end of the rotating plate 751, and the lower end of the pull rod 752 is connected to the inner cylinder 2 through the fourth elastic element so as to drive the pull rod 752 to move when the inner cylinder 2 moves vertically downward. The two ends of the third elastic element 753 are respectively connected to the first mounting seat 71 and the outer cylinder 1, and are used to drive the first mounting seat 71 to move vertically downward. Specifically, the third elastic element 753 is used to reset the first mounting seat 71. The fourth driving mechanism 75 also includes a connecting plate 754, which is located above the outer cylinder 1. The first mounting seat 71 is rotatably mounted on the connecting plate 754. The connecting plate 754 is elastically and telescopically mounted on the upper end of the outer cylinder 1 through the third elastic element 753, and the first mounting seat 71 is driven to move vertically through the connecting plate 754.

[0055] The specific working principle of this application is as follows: First, the motor 42 drives the drill bit 3 to rotate through the connecting shaft 41. While the connecting shaft 41 rotates, the inner cylinder 2 moves vertically downward through the linkage component 5. At this time, the drill bit 3 rotates on its own and moves downward with the inner cylinder 2, so that the drill bit 3 can drill into the ground and fix the entire device. While the inner cylinder 2 moves downward, the mating part 22 abuts against the connecting part 611 and pushes the mounting rod 61 to move vertically downward. Since the entire device is on a slope, some of the support leg components 6 will contact the ground first. At this time, the telescopic rod 62 in the support leg component 6 that contacts the ground first retracts into the mounting rod 61, and the ball joint support 64 adapts to rotate and fits against the slope. The support leg components 6 that do not contact the ground continue to move downward until they contact the ground. At this time, all the support leg components 6 are in contact with the ground. Through the cooperation of the drill bit 3 and multiple support leg components 6, the purpose of fixing the entire device is achieved.

[0056] Furthermore, while the inner cylinder 2 moves downward, the fourth elastic element pulls the pull rod 752 downward. The pull rod 752 drives the rotating plate 751 to rotate, thereby tilting the connecting plate 754 through the rotating plate 751, causing the first mounting seat 71 to move upward, thereby pulling the locking member 711 out of the locking hole 21 and canceling the limitation on the first mounting seat 71.

[0057] The surveying instrument is then placed on the second mounting base 73. The third drive mechanism 82 drives the clamping plate 81 to clamp the surveying instrument, thereby fixing the surveying instrument on the second mounting base 73 for surveying. During the surveying process, the first drive mechanism 72 drives the first mounting base 71 and the second drive mechanism 74 drives the second mounting base 73 to adjust the direction and angle of the surveying instrument, thereby adjusting the surveying angle of the surveying instrument and completing surveying in multiple directions and at multiple angles.

[0058] 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.
