Description

Technical Field

[0001] This application relates to the field of surveying tripod technology, and more particularly to a device for topographic surveying. Background Technology

[0002] Topographic surveying is the work of determining the projection position and elevation of features and topography on the Earth's surface onto a horizontal plane, which is then used for engineering construction, planning and design, and administrative management, and has a wide range of applications in economic and national defense construction. Existing topographic surveying instruments are mainly used for data acquisition, processing, and output. Traditional surveying instrument supports typically use three support rods to support the instrument at the ideal height and horizontal position to complete data acquisition. However, when using existing support structures, since surveying sites are mostly in the field with complex terrain and ground environments, adjusting the balance requires constantly adjusting the relative lengths and positional relationships between the three support rods. This operation is cumbersome and difficult, often requiring a lot of time to adjust the support structure, resulting in low surveying efficiency and poor accuracy in topographic data mapping.

[0003] Therefore, there is an urgent need for a support structure for topographic surveying to solve the defects of the existing topographic surveying equipment in actual use. Summary of the Invention

[0004] This application proposes a topographic surveying device that can automatically adjust the state of the support structure according to the flatness of the ground, so that the topographic surveying equipment on it is in a horizontal state. It is simple to operate and easy to use. At the same time, it has the advantages of high accuracy in topographic surveying. This solves the problem that when using existing support structures, the surveying sites are mostly in the field with complex terrain and ground environment. When adjusting the balance, it is necessary to constantly adjust the relative length and position relationship between the three support rods. The operation is cumbersome and difficult, and often a lot of time is spent on adjusting the support structure. The surveying efficiency is relatively low, and the accuracy of topographic data is poor.

[0005] To achieve the above objectives, this application adopts the following technical solution: a topographic surveying device, comprising a connecting frame, an ear seat provided on the outer surface of the connecting frame, and an electromagnetic support leg pinned to the outer surface of the connecting frame through the ear seat; a threaded sleeve rod threadedly connected to the bottom of the connecting frame, and the threaded sleeve rod and the electromagnetic support leg being connected by a connecting rod transmission; an adjusting component fixedly installed at the top of the connecting frame, the adjusting component comprising a fixed plate whose bottom end is fixedly connected to the top of the connecting frame, and a swing member provided in the inner cavity of the fixed plate; the inner cavity of the swing member being connected by an elastic element to a fixed shaft fixedly installed at the top of the connecting frame; and a platform fixedly installed at the top of the fixed plate.

[0006] Furthermore, an annular groove is formed on the inner wall of the fixed plate, and three sets of sensing components arranged in an annular array are respectively provided on the upper and lower sides of the inner wall of the annular groove. The pendulum includes a connecting ring whose inner wall is connected to the fixed shaft through an elastic element. A counterweight block whose outer surface is in contact with the inner wall of the annular groove is fixedly installed on one side of the outer surface of the connecting ring. A baffle plate symmetrically arranged with the counterweight block for blocking the signal of the sensing components is fixedly installed on the other side of the outer surface of the connecting ring.

[0007] Furthermore, the three sets of sensing components are arranged in a segmented structure, and their effective coverage area is smaller than the blocking area of ​​the fan-shaped baffle. At the same time, the sensing components form a feedback electrical connection with the electromagnetic legs at symmetrical positions. When the sensing component at the corresponding position is blocked, the electromagnetic leg at the symmetrical position is triggered and extends, and its extension amount is directly proportional to the amount of blocking of the sensing component at the symmetrical position.

[0008] Furthermore, a carbon ring is provided on the inner wall of the annular groove, and a carbon brush is provided on the outer surface of the counterweight, which makes a conductive connection when it contacts the carbon ring. A second conductive block is provided on one side of the outer surface of the ear seat, and a first conductive block is provided on one side of the inner wall of the top of the electromagnetic leg, which can make conductive contact with it. The carbon ring, carbon brush, first conductive block and second conductive block form a conductive series circuit to the electromagnetic leg.

[0009] Furthermore, a gap exists between the connecting ring and the fixed shaft, and an elastic element is provided in the gap, so that a transmission connection is formed between the connecting ring and the fixed shaft. When the fixed plate tilts, the connecting ring tilts under the influence of the weight of the counterweight and compresses the elastic element, thereby conducting the series circuit to the electromagnetic support leg. When the fixed plate is adjusted to a horizontal state, the elastic force of the elastic element causes the connecting ring to return to its initial state, so that the carbon ring and the carbon brush on the counterweight are in a non-contact state, thereby cutting off the conductive connection to the electromagnetic support leg.

[0010] Furthermore, under the action of the elastic element, the end of the connecting ring is in a non-contact state with the end face of the fixed plate, thereby effectively reducing the frictional resistance when the swinging part swings and deflects in the tilted state of the fixed plate.

[0011] The topographic surveying device provided in this application allows for the adjustment of components and their structures. By adjusting the tilt of the fixed plate, the device can deflect the pendulum while simultaneously using the upper baffle to block the sensing components at the corresponding positions, thereby generating a feedback signal to regulate the extension of the electromagnetic legs at symmetrical positions until the fixed plate and the topographic surveying device on it are in a horizontal state. The device is simple to operate and easy to use, and it also provides high accuracy in topographic surveying. Attached Figure Description

[0015] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this invention.

[0016] like Figure 1 As shown, a topographic surveying device includes a connecting frame 1. Three sets of lugs 2 arranged in a circular array are provided on the outer surface of the connecting frame 1. Electromagnetic legs 3 are pinned to the outer surface of the connecting frame 1 via the lugs 2. A threaded sleeve 4 is threadedly connected to the bottom of the connecting frame 1. The threaded sleeve 4 and the electromagnetic legs 3 are connected via a connecting rod. Thus, during the up-and-down movement of the rotating threaded sleeve 4, the degree of separation between the three sets of electromagnetic legs 3 is adjusted via the connecting rod, thereby adjusting the relative height of the connecting frame 1. An adjusting component 5 is fixedly installed at the top of the connecting frame 1. Figure 2As shown, the adjusting component 5 includes a fixed plate 10 whose bottom end is fixedly connected to the top end of the connecting frame 1. A swing member 8 is provided in the inner cavity of the fixed plate 10. The inner cavity of the swing member 8 is connected to the fixed shaft 7 fixedly installed on the top end of the connecting frame 1 through an elastic member 9. When the fixed plate 10 tilts, the swing member 8 can swing and deflect to the tilted side, and feed back the swing and deflection signal to the electromagnetic support leg 3 at the corresponding position, thereby adjusting the extension of the electromagnetic support leg 3 at the corresponding position, so that the fixed plate 10 is in a horizontal state during the continuous adjustment process. A platform 6 for supporting the topographic surveying equipment is fixedly installed on the top end of the fixed plate 10.

[0017] like Figure 2 , Figure 3 As shown, in this technical solution, an annular groove 11 is provided on the inner wall of the fixed disk 10, and three sets of sensing components 13 arranged in an annular array are respectively provided on the upper and lower sides of the inner wall of the annular groove 11. The swing member 8 includes a connecting ring 14 whose inner wall is connected to the fixed shaft 7 through an elastic member 9. A counterweight 16 is fixedly installed on one side of the outer surface of the connecting ring 14, and the outer surface of the counterweight 16 is in contact with the inner wall of the annular groove 11. A baffle 15, which is symmetrically arranged with the counterweight 16 and used to block the signal of the sensing component 13, is fixedly installed on the other side of the outer surface of the connecting ring 14. When the fixed disk 10 tilts, the counterweight 16 deflects under the influence of gravity. The baffle 15 at the symmetrical position blocks the signal of the sensing component 13 at the corresponding position, thereby determining the tilt direction of the fixed disk 10 and adjusting the extension of the electromagnetic support leg 3 at the corresponding position until the fixed disk 10 is in a horizontal state.

[0018] like Figure 2 As shown, in this technical solution, the three sets of sensing components 13 are arranged in a segmented structure, and their effective coverage area is smaller than the blocking area of ​​the fan-shaped baffle 15. At the same time, the sensing components 13 form a feedback electrical connection with the electromagnetic legs 3 at symmetrical positions. When the sensing component 13 at the corresponding position is blocked, the electromagnetic legs 3 at the symmetrical position are triggered and extended, and the extension amount is directly proportional to the amount of blocking of the sensing component 13 at the symmetrical position. The sensing component 13 can be configured as a grating sensing device or an electromagnetic sensing device according to the actual use, and the tilt direction of the fixed disk 10 is fed back and transmitted by blocking the signal through the baffle 15.

[0019] like Figure 3 , Figure 5 as well as Figure 6As shown, in this technical solution, a carbon ring 12 is provided on the inner wall of the annular groove 11. At the same time, a carbon brush is provided on the outer surface of the counterweight 16, and a conductive connection is formed when it contacts the carbon ring 12. A second conductive block 18 is provided on one side of the outer surface of the ear seat 2, and a first conductive block 17 is provided on one side of the inner wall of the top of the electromagnetic support leg 3, which can form a conductive contact with it. A conductive series circuit for the electromagnetic support leg 3 is formed between the carbon ring 12, the carbon brush, the first conductive block 17 and the second conductive block 18, thereby controlling the conduction state of the electromagnetic support leg 3. The arrangement of the first conductive block 17 and the second conductive block 18 ensures that the electromagnetic support leg 3 on the device is always de-energized when the device is in the retracted state.

[0020] like Figure 4 As shown, in this technical solution, a gap exists between the connecting ring 14 and the fixed shaft 7, and an elastic element 9 is provided in the gap, so that a transmission connection is formed between the connecting ring 14 and the fixed shaft 7. When the fixed disk 10 tilts, the connecting ring 14 tilts under the influence of the gravity of the counterweight 16 and compresses the elastic element 9, thereby conducting the series circuit to the electromagnetic support leg 3. When the fixed disk 10 is adjusted to a horizontal state, the elastic force of the elastic element 9 causes the connecting ring 14 to return to its initial state, so that the carbon ring 12 and the carbon brush on the counterweight 16 are in a non-contact state, thereby cutting off the conductive connection to the electromagnetic support leg 3, so as to keep the fixed disk 10 in a relatively balanced state for a long time.

[0021] In this technical solution, under the action of the elastic element 9, the end of the connecting ring 14 is in a non-contact state with the end face of the fixed plate 10, thereby effectively reducing the frictional resistance of the swinging part 8 when it swings and deflects in the tilted state of the fixed plate 10, and improving the flexibility of the adjusting part 5 and the mapping accuracy of the topographic surveying equipment on it for topographic data.
