Description

Technical Field

[0001] The present invention relates to a construction site surveying device and a using method, belonging to the technical field of surveying. Background Art

[0002] The construction site indeed refers to the area demarcated for the specific construction activities of the engineering project. Within this area, advanced surveying and mapping equipment such as total stations is usually used for precise measurement and positioning. A total station is a high-end measuring instrument integrating optical, electronic technology, and modern computer technology, and is commonly used in various occasions such as building construction, topographic surveying, and deformation monitoring to ensure the accuracy and reliability of various data during the construction process.

[0003] In practical applications, in order to ensure the working accuracy of the total station, it is first necessary to place it on a stable support frame and place the frame at a suitable observation position within the construction site. However, due to possible deviations during the placement process, the support frame is prone to tilting, which will directly affect the horizontal state of the total station. In order to ensure that the total station can perform normal surveying operations, generally, leveling operations need to be carried out on the total station. Currently, there are mainly two leveling operation methods:

[0004] 1. Manual leveling: Relying on the experience and skills of the operator, by observing and adjusting the bubble level or electronic level on the total station to reach the horizontal state. Novice operators may, due to lack of experience or unskilled operation, easily overlook the leveling step or cause leveling errors, which may affect the accuracy of the final measurement data.

[0005] 2. Electric control automatic leveling: Some advanced total stations are equipped with an automatic leveling system that uses built-in sensors to detect the relative relationship between the instrument and the ground and adjusts the instrument's attitude to horizontal in real time through complex algorithms. Although this method theoretically improves the leveling efficiency and accuracy, in the actual construction environment, the sensors may be affected by small stones and impurities on the ground, resulting in distorted distance information collected, thereby affecting the effect of electric control leveling and may also have an adverse impact on the surveying accuracy of the total station. Summary of the Invention

[0006] In view of the problems in the prior art, the present invention provides a construction site surveying device and a using method.

[0007] The technical solution adopted by the present invention to solve its technical problems is: A construction site surveying device includes a total station main body.

The three support brackets are arranged in a tapered structure with a narrow upper part and a wide lower part.

[0011] Further, the driving member includes a rectangular cylinder. The rectangular cylinder is installed in the middle of the lower end of the pallet and is located directly above the bottom cylinder. A movable plate is slidably connected inside the rectangular cylinder. A connecting rod arranged vertically is installed in the middle of the lower end of the movable plate. The lower end of the connecting rod extends out of the lower side of the rectangular cylinder and is movably connected to the bottom cylinder;

[0012] A second magnetic plate is installed at the upper end of the movable plate. A first magnetic plate is arranged directly above the second magnetic plate, and the first magnetic plate and the second magnetic plate are arranged to repel each other. The first magnetic plate is located inside the rectangular cylinder. An auxiliary component is installed at the outer end of the first magnetic plate, and the auxiliary component is movably arranged inside the rectangular cylinder.

[0013] Further, the auxiliary component includes a rectangular frame. The first magnetic plate is installed inside the rectangular frame, and the rectangular frame is located inside the rectangular cylinder. A rotating shaft is arranged in the middle of the rear end of the rectangular frame. The rotating shaft is rotatably connected to the inner rear wall of the rectangular cylinder;

[0014] A connecting cylinder is installed in the middle of the front end of the rectangular frame. The connecting cylinder extends to the front end of the rectangular cylinder and is rotatably connected to the rectangular cylinder. A second elastic member is installed on the inner rear wall of the connecting cylinder.

An operation plate is installed at the front end of the round rod, and the operation plate is located inside the second straight cylinder and fits against the front end of the rectangular cylinder;

[0015] A plurality of clamping bars are equidistantly installed on the inner wall of the connecting cylinder, and the clamping bars are arranged along the length direction of the connecting cylinder.

[0018] A using method of a construction site surveying device includes the following steps:

[0019] First step: First, carry and place the surveying device at a suitable position on the construction site, and then use the operation plate to rotate the first magnetic plate, so that the first magnetic plate and the second magnetic plate are arranged in a mutually repulsive manner;

[0020] Second step: Under the action of the repulsive force generated between the first magnetic plate and the second magnetic plate, the second magnetic plate, the movable plate and the connecting rod move downward, so that the bottom cylinder moves downward, and a plurality of inverted U-shaped rods move downward synchronously, so that the second piston moves downward, and the gas in the second straight cylinder is conveyed to the first straight cylinder through the U-shaped pipe, so that the first piston moves upward, so that the ejector rod moves upward and contacts the lower end of the total station main body.

[0021] Third step: Start the total station main body, and perform centering, rough leveling and fine leveling operations on the total station main body, so as to complete the surveying operation.

[0022] The beneficial effects of the present invention:

[0023] 1. By utilizing the first magnetic plate and the second magnetic plate, the connecting rod, the bottom cylinder, the inverted U-shaped rod, and the second piston move downward, causing the first piston and the ejector rod to move upward. When the support plate is in an inclined state, the first pistons and the ejector rods in different first straight cylinders will move upward by different distances. With the assistance of the first universal joint, the total station body and the support plate will be in a parallel state, realizing the automatic mechanical leveling operation of the total station body, effectively reducing the probability of errors caused by unskilled, improper, or forgotten operations, effectively ensuring the survey quality of the total station body, and with the assistance of the chamfer of the bottom cylinder, the granular impurities will move outward along the chamfer surface, thereby enabling effective contact between the bottom cylinder and the construction base surface, effectively ensuring the leveling operation of the total station body, and further ensuring the survey quality of the total station body.

[0024] 2. The concave hole can be separated from the fixed rod, and the operating plate and the round rod can rotate. With the cooperation of the clamping strip and the clamping groove, the connecting cylinder, the rectangular frame, and the first magnetic plate can rotate 180°, which is used to complete the mechanical storage or unfolding of components such as the bottom cylinder. Under the elastic force of the second elastic member, the fixed rod will be inserted back into the concave hole, and then the operating plate and the rectangular cylinder will be reinstalled in a restricted manner, realizing the convenient conversion operation of the magnetic pole of the first magnetic plate, effectively ensuring the stability of the first magnetic plate after conversion, enabling an effective force to be formed between the first magnetic plate and the second magnetic plate, and enabling effective storage or unfolding movement of components such as the bottom cylinder.

[0025] 3. During the up and down movement of the bottom cylinder, with the assistance of the L-shaped frame and the support arm, the support bracket moves outward or inward, achieving the linkage between the up and down movement of the bottom cylinder and the unfolding and folding movement of the support bracket, effectively reducing the operation procedures.

Specific embodiments

[0040] In order to make the technical means, creative features, achieved purposes and effects of the present invention easy to understand, the present invention will be further described below in conjunction with specific embodiments.

[0041] Embodiment 1:

[0042] Such as Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 6 and Figure 7As shown in the figure, a construction site surveying device is provided, including a total station main body 1. The first universal joint 11 arranged in the middle of the upper end of the support plate 2 is installed on the middle of the lower end of the total station main body 1. Through the first universal joint 11, the total station main body 1 is movably connected to the support plate 2;

[0043] Three support brackets 7 arranged in a tapered structure with a narrow upper part and a wide lower part and located outside the bottom cylinder 5 and whose lower end faces coincide with the lower end face of the bottom cylinder 5 are equidistantly and movably arranged on the lower end of the support plate 2. The three support brackets 7 are used in cooperation to lift the support plate 2;

[0044] A plurality of first elastic members 21 located outside the first universal joint 11 and outside the top rod 22 are equidistantly installed between the support plate 2 and the total station main body 1. The plurality of first elastic members 21 are used in cooperation to lift the total station main body 1. The first elastic member 21 can be a spring.

[0045] During use, first, components such as the total station main body 1 are carried to a suitable position on the construction site. Then, the three support brackets 7 are unfolded and the unfolded three support brackets 7 are placed on the construction base surface. At this time, the first elastic member 21 and the first universal joint 11 will lift and install the total station main body 1 on the upper end of the support plate 2, thus completing the erection of the total station main body 1. Then, the total station main body 1 is used to survey the construction site.

[0046] Embodiment 2:

[0047] As shown in Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 、 Figure 5 、 Figure 6 、 Figure 7 、 Figure 8 、 Figure 9 、 Figure 10 and Figure 12 shown, the rectangular cylinder 3 located directly above the bottom cylinder 5 is installed on the middle of the lower end of the support plate 2. Through the rectangular cylinder 3, an installation space is provided for components such as the movable plate 41, and the movable plate 41 is slidably connected in the rectangular cylinder 3. Through the movable plate 41, an installation carrier is provided for components such as the connecting rod 4, and then the vertically arranged connecting rod 4 is installed on the middle of the lower end of the movable plate 41;

[0048] The bottom cylinder 5 is movably connected to the lower end of the connecting rod 4 extending out of the lower side of the rectangular cylinder 3 through the second universal joint. Through the connecting rod 4, the bottom cylinder 5 is connected to the movable plate 41. Chamfers 52 are provided on the outer edge and the inner edge of the lower end of the bottom cylinder 5. By using the chamfers 52, obstacles such as stones can be pushed;

[0049] The second magnetic plate 42 is installed on the upper end of the movable plate 41, and the first magnetic plate 32, which is arranged to be mutually repulsive with the second magnetic plate 42 and is located within the rectangular cylinder 3, is disposed directly above the second magnetic plate 42. The first magnetic plate 32 and the second magnetic plate 42 are used in cooperation to enable the movable plate 41 to move downward. The first magnetic plate 32 is installed inside the rectangular frame 33 located within the rectangular cylinder 3, and the rotating shaft 34 rotatably connected to the rear wall inside the rectangular cylinder 3 is arranged at the middle of the rear end of the rectangular frame 33. Through the rotating shaft 34, the rectangular frame 33 is rotatably connected to the rectangular cylinder 3;

[0050] A plurality of first straight cylinders 8 arranged vertically and located above the bottom cylinder 5 are equidistantly installed on the lower end of the support plate 2. Through the first straight cylinders 8, on the one hand, an installation carrier is provided for the second straight cylinder 82, and on the other hand, an installation space is provided for components such as the first piston 23. The second straight cylinder 82, which is located below the support plate 2, outside the rectangular cylinder 3, and arranged vertically, is disposed at the rear end of the first straight cylinder 8. Through the second straight cylinder 82, an installation space is provided for the second piston 61;

[0051] The second piston 61 is slidably connected inside the second straight cylinder 82. By using the second piston 61, a sealed space is formed inside the second straight cylinder 82. One vertical portion of a plurality of inverted U-shaped rods 6 is movably arranged equidistantly on the upper end of the bottom cylinder 5 through a third universal joint. Then, the lower end of the other vertical portion of the inverted U-shaped rod 6 extends into the second straight cylinder 82 and is connected to the second piston 61. Through the inverted U-shaped rod 6, the bottom cylinder 5 is connected to the second piston 61;

[0052] The U-shaped pipe 81, whose other end is communicatively arranged at the lower end of the second straight cylinder 82, is communicatively installed at the lower end of the first straight cylinder 8. Through the U-shaped pipe 81, the first straight cylinder 8 and the second straight cylinder 82 are communicatively arranged. The first piston 23 is slidably connected inside the first straight cylinder 8. By using the first piston 23, a sealed space is formed inside the first straight cylinder 8. Then, the top rod 22, whose upper end penetrates through the support plate 2, fits with the total station main body 1, is slidably connected to the support plate 2, and is arranged vertically, is installed at the middle of the upper end of the first piston 23. Through the top rod 22, the total station main body 1 can be lifted.

[0053] When the total station main body 1 is erected, the rectangular frame 33 and the first magnetic plate 32 are flipped by 180°, so that the first magnetic plate 32 and the second magnetic plate 42 are arranged to be mutually repulsive. As a result, a repulsive force is generated between the first magnetic plate 32 and the second magnetic plate 42. Under the action of the repulsive force, the second magnetic plate 42 moves downward, and then the movable plate 41 moves downward along the rectangular cylinder 3, thereby causing the connecting rod 4 to move downward;

[0054] Furthermore, the bottom cylinder 5 moves downward, causing multiple inverted U-shaped rods 6 to move downward synchronously. As a result, the second piston 61 moves downward along the second straight cylinder 82, enabling the gas in the second straight cylinder 82 to be transported to the first straight cylinder 8 through the U-shaped tube 81. Consequently, the air pressure in the first straight cylinder 8 increases, causing the first piston 23 to move upward along the first straight cylinder 8 under the action of the air pressure. Subsequently, the top rod 22 moves upward and contacts the lower end of the total station body 1, thereby using multiple top rods 22 to lift the total station body 1;

[0055] When the support plate 2 is in an inclined state, after the bottom cylinder 5 fully contacts the construction base surface, an included angle state exists between the bottom cylinder 5 and the support plate 2. Thus, under the action of the inverted U-shaped rod 6, the second pistons 61 in different second straight cylinders 82 are in different positions. As a result, the air pressures in different first straight cylinders 8 are different, causing the first pistons 23 and top rods 22 in different first straight cylinders 8 to move upward by different distances. Subsequently, with the assistance of the first universal joint 11, the total station body 1 and the support plate 2 will be in an included angle state and a parallel state, realizing automatic mechanical leveling operation of the total station body 1, effectively reducing the probability of errors caused by unskilled, improper, or forgotten operations, and effectively ensuring the survey quality of the total station body 1;

[0056] During the contact process between the bottom cylinder 5 and the construction base surface, if there are granular impurities such as small stones at the contact position of the construction base surface, the granular impurities will first contact the chamfer 52 surface of the bottom cylinder 5. Under the thrust of the downward movement of the bottom cylinder 5, the granular impurities will move outward along the chamfer 52 surface, enabling effective contact between the bottom cylinder 5 and the construction base surface, effectively ensuring the leveling operation of the total station body 1, and further ensuring the survey quality of the total station body 1;

[0057] After the survey is completed, the rectangular frame 33 and the first magnetic plate 32 can be flipped 180° with the assistance of the rotating shaft 34. As a result, the first magnetic plate 32 and the second magnetic plate 42 are arranged in mutual adsorption, generating an adsorption force between the first magnetic plate 32 and the second magnetic plate 42. Under the action of the adsorption force, the second magnetic plate 42, the movable plate 41, the connecting rod 4, and the bottom cylinder 5 return upward to their original positions, realizing mechanical storage of components such as the bottom cylinder 5, and effectively ensuring normal handling operations in the future.

[0058] Embodiment 3:

[0059] To facilitate the flipping operation, a handle structure is generally used to flip the first magnetic plate 32 conveniently. However, the first magnetic plate 32 is prone to phenomena such as self-rotation after flipping, resulting in poor stability of the first magnetic plate 32, which affects the force formed between the first magnetic plate 32 and the second magnetic plate 42, and thus affects the storage or deployment movement of components such as the bottom cylinder 5.

[0060] To solve the above problems, asFigure 2 , Figure 4 , Figure 5 , Figure 10 , Figure 11 and Figure 12 As shown in Figure 10 , Figure 11 , and Figure 12 , a connecting cylinder 36 extending to the front end of the rectangular cylinder 3 and rotatably connected to the rectangular cylinder 3 is installed at the middle of the front end of the rectangular frame 33. Through the connecting cylinder 36, on the one hand, the rectangular frame 33 is rotatably connected to the rectangular cylinder 3, and on the other hand, an installation space is provided for components such as the second elastic member 35. The second elastic member 35 is installed on the inner rear wall of the connecting cylinder 36, and the front end face of the round rod 37 provided at the front end of the second elastic member 35 coincides with the front end face of the connecting cylinder 36. By using the second elastic member 35, the round rod 37 is movably connected to the connecting cylinder 36. The second elastic member 35 can be a spring;

[0061] An operation plate 31 located inside the second straight cylinder 82 and attached to the front end of the rectangular cylinder 3 is installed at the front end of the round rod 37. Through the operation plate 31, the round rod 37 can be rotated. A plurality of strip-shaped protrusions 361 arranged along the length direction of the connecting cylinder 36 and located outside the second elastic member 35 are equidistantly installed on the inner wall of the connecting cylinder 36. A plurality of card slots 371 extending to the rear end of the round rod 37 and slidably connected to the outer ends of the strip-shaped protrusions 361 are formed by inward depressions on the outer end face of the round rod 37. The card slots 371 and the strip-shaped protrusions 361 are used in cooperation to make the round rod 37 and the connecting cylinder 36 engage with each other;

[0062] Two concave holes 311 penetrating the operation plate 31 are formed by backward depressions on the front end face of the operation plate 31. Two fixing rods 38 located on the left and right sides of the connecting cylinder 36 and placed in the concave holes 311 are symmetrically arranged on the front end of the rectangular cylinder 3. The concave holes 311 and the fixing rods 38 are used in cooperation to restrict the installation of the operation plate 31 and the rectangular cylinder 3.

[0063] When in use, first hold the operation plate 31 and pull it forward, so that the round rod 37 moves forward along the connecting cylinder 36, and the second elastic member 35 is stretched to generate an elastic force. At the same time, the concave holes 311 and the fixing rods 38 are separated. Then rotate the operation plate 31 by 180°, so that the round rod 37 rotates. Under the cooperation of the strip-shaped protrusions 361 and the card slots 371, the connecting cylinder 36 rotates, and thus, with the assistance of the rotating shaft 34, the rectangular frame 33 and the first magnetic plate 32 rotate by 180° to complete the mechanical storage or deployment of components such as the bottom cylinder 5;

[0064] Then release the operation board 31, and under the elastic force of the second elastic member 35, the round rod 37 will move backward along the connecting cylinder 36, further causing the operation board 31 to move backward and reattach to the rectangular cylinder 3, so that the fixing rod 38 is inserted back into the concave hole 311, and then the operation board 31 and the rectangular cylinder 3 are reinstalled with restricted movement, realizing a convenient conversion operation of the magnetic pole of the first magnetic plate 32, effectively ensuring the stability of the first magnetic plate 32 after conversion, enabling an effective force to be formed between the first magnetic plate 32 and the second magnetic plate 42, and enabling effective storage or deployment movement of components such as the bottom cylinder 5.

[0065] Embodiment 4:

[0066] During the use of the device, first perform the deployment operation on the support bracket 7 to complete the erection of the total station main body 1, then perform the leveling operation on the total station main body 1, and then use the total station main body 1 for surveying operations. After the survey is completed, first store the leveling structure, then store the support bracket 7, and then carry the device, which makes the operation process of the device more complex.

[0067] To solve the above problems, as Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 and Figure 7 shown, the transverse portions of three L-shaped frames 51 on the inner side of the support bracket 7 are equidistantly installed on the outer end of the bottom cylinder 5, and the support arm 71 is movably installed on the upper side of the outer end of the vertical portion of the L-shaped frame 51, while the other end of the support arm 71 is movably arranged on the lower side of the inner end of the support bracket 7. Through the support arm 71, the L-shaped frame 51 and the support bracket 7 are movably connected, and the three support arms 71 are arranged in a tapered structure with a narrower upper part and a wider lower part.

[0068] During the downward movement of the bottom cylinder 5, the three L-shaped frames 51 will move downward synchronously, further causing the inner part of the support arm 71 to move downward, thereby causing the outer part of the support arm 71 to move outward, and then causing the support bracket 7 to move outward and expand. During the upward movement of the bottom cylinder 5, the three L-shaped frames 51 will move upward synchronously, and with the assistance of the support arm 71, the support bracket 7 will move inward and be stored, achieving a linkage between the up and down movement of the bottom cylinder 5 and the expansion and storage movement of the support bracket 7, effectively reducing the operation process.

[0069] A method for using a construction site survey device includes the following steps:

[0070] First step, first carry and place the survey device at a suitable position on the construction site, and then use the operation board 31 to rotate the first magnetic plate 32, so that the first magnetic plate 32 and the second magnetic plate 42 are arranged in mutual repulsion;

[0071] Step 2: Under the repulsive force generated between the first magnetic plate 32 and the second magnetic plate 42, the second magnetic plate 42, the movable plate 41, and the connecting rod 4 move downward, thereby causing the bottom cylinder 5 to move downward, and causing the plurality of inverted U-shaped rods 6 to move downward synchronously. Furthermore, the second piston 61 moves downward, and the gas in the second straight cylinder 82 is transported to the first straight cylinder 8 through the U-shaped pipe 81, so that the first piston 23 moves upward. Furthermore, the ejector rod 22 moves upward and contacts the lower end of the total station main body 1. When the lower end of the bottom cylinder 5 contacts the construction base surface under the repulsive force, the plurality of ejector rods 22 will lift the total station main body 1 at multiple points, and make the total station main body 1 parallel to the construction base surface;

[0072] Step 3: Start the total station main body 1, and perform centering, rough leveling, and fine leveling operations on the total station main body 1, thereby completing the survey operation.

[0073] Although this specification is described according to the implementation manners, not each implementation manner only contains an independent technical solution. This narrative manner of the specification is only for clarity. Those skilled in the art should regard the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other implementation manners that can be understood by those skilled in the art.
