Description

Technical Field

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

[0002] The construction site does refer to the area designated for the specific construction activities of the project. In this area, advanced surveying and mapping equipment such as total stations are usually used for precise measurement and positioning. Total stations are high-end measuring instruments that integrate optics, electronic technology and modern computer technology. They are often used in various occasions such as construction, topographic measurement, deformation monitoring, etc. to ensure that all data during the construction process are accurate and reliable.

[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 in a suitable position for observation in the construction site. However, due to possible deviations during the placement process, the support frame is prone to tilt, which will directly affect the horizontal state of the total station. In order to ensure that the total station can perform normal survey operations, the total station is generally required to be leveled. There are currently two main leveling operation methods: 1. Manual leveling: It depends on the operator's experience and skills. The operator observes and adjusts the bubble level or electronic level on the total station to reach a horizontal state. Novice operators may easily ignore the leveling steps or cause leveling errors due to lack of experience or unskilled operation, which may affect the accuracy of the final measurement data.

[0004] 2. Electronically controlled 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 posture to horizontal in real time through complex algorithms. Although this method theoretically improves the efficiency and accuracy of leveling, in actual construction environments, the sensor may be affected by small stones and impurities on the ground, resulting in distortion of the collected distance information, which in turn affects the effect of electronically controlled leveling and may also have an adverse effect on the survey accuracy of the total station.

The bottom cylinder 5 is connected to the movable plate 41 through the connecting rod 4. Chamfers 52 are provided on the outer edge and the inner edge of the lower end of the bottom cylinder 5. The chamfers 52 can be used to push obstacles such as stones. 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 repel each other with the second magnetic plate 42 and is located in the rectangular tube 3 is arranged directly above the second magnetic plate 42. The first magnetic plate 32 and the second magnetic plate 42 are used in conjunction with each other to move the movable plate 41 downward, and the first magnetic plate 32 is installed inside the rectangular frame 33 located in the rectangular tube 3, and the rotating shaft 34 which is rotatably connected to the inner rear wall of the rectangular tube 3 is set in the middle of the rear end of the rectangular frame 33, and the rectangular frame 33 is rotatably connected to the rectangular tube 3 through the rotating shaft 34; 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 cylinder 8, a mounting carrier is provided for the second straight cylinder 82 on the one hand, and a mounting space is provided for the first piston 23 and other components on the other hand. A second straight cylinder 82 located at the lower side of the support plate 2 and outside the rectangular cylinder 3 and arranged vertically is arranged on the rear end of the first straight cylinder 8. Through the second straight cylinder 82, a mounting space is provided for the second piston 61; The second piston 61 is slidably connected to the inside of the second straight cylinder 82, and a sealed space is formed inside the second straight cylinder 82 by using the second piston 61. A vertical portion of a plurality of inverted U-shaped rods 6 is equidistantly movably arranged on the upper end of the bottom cylinder 5 through a third universal joint, and then the lower end of another vertical portion of the inverted U-shaped rod 6 is extended into the second straight cylinder 82 and connected to the second piston 61. The bottom cylinder 5 is connected to the second piston 61 through the inverted U-shaped rod 6; The U-shaped tube 81 whose other end is connected to the lower end of the second straight cylinder 82 is connected and installed on the lower end of the first straight cylinder 8. The first straight cylinder 8 and the second straight cylinder 82 are connected through the U-shaped tube 81, and the first piston 23 is slidably connected in the first straight cylinder 8. A sealed space is formed in the first straight cylinder 8 through the first piston 23. Then, the push rod 22, whose upper end passes through the support plate 2 and fits with the total station body 1 and is slidably connected to the support plate 2 and is vertically arranged, is installed on the middle part of the upper end of the first piston 23. The total station body 1 can be lifted by the push rod 22.

[0024] When the total station body 1 is erected, the rectangular frame 33 and the first magnetic plate 32 are flipped 180 degrees, so that the first magnetic plate 32 and the second magnetic plate 42 are arranged to repel each other, thereby generating a repulsive force between the first magnetic plate 32 and the second magnetic plate 42, and under the action of the repulsive force, the second magnetic plate 42 moves downward, thereby causing the movable plate 41 to move downward along the rectangular tube 3, thereby causing the connecting rod 4 to move downward; Then the bottom cylinder 5 moves downward, so that the multiple inverted U-shaped rods 6 move downward synchronously, and then the second piston 61 moves downward along the second straight cylinder 82, so that the gas in the second straight cylinder 82 is transported to the first straight cylinder 8 through the U-shaped tube 81, and then the air pressure in the first straight cylinder 8 is increased, so that the first piston 23 moves upward along the first straight cylinder 8 under the action of the air pressure, and then the push rod 22 moves upward and contacts with the lower end of the total station body 1, so that the total station body 1 is lifted by the multiple push rods 22; When the support plate 2 is in an inclined state, after the bottom cylinder 5 is fully in contact with the construction base surface, an angle is formed between the bottom cylinder 5 and the support plate 2, so that under the action of the inverted U-shaped rod 6, the second pistons 61 in different second straight cylinders 82 are in different positions, and the air pressures in different first straight cylinders 8 are different, so that the first pistons 23 and the push rods 22 in different first straight cylinders 8 move upward by different distances, and then, with the assistance of the first universal joint 11, an angle is formed between the total station body 1 and the support plate 2, and the total station body 1 and the support plate 2 are parallel, so that the total station body 1 is automatically mechanically leveled, 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; 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 chamfered corner 52 of the bottom cylinder 5, and under the thrust of the bottom cylinder 5 moving downward, the granular impurities will move outward along the chamfered corner 52, thereby effectively contacting the bottom cylinder 5 with 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; When 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, so that the first magnetic plate 32 and the second magnetic plate 42 are arranged to be adsorbed to each other, and an adsorption force is generated 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 tube 5 return to their original positions upward, thereby realizing mechanical storage of the bottom tube 5 and other components, and effectively ensuring subsequent normal handling operations.

[0025] Embodiment three:

[0026] In order to facilitate the flipping operation, a handle structure is generally used to easily flip the first magnetic plate 32. However, the first magnetic plate 32 is prone to 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, causing the storage or unfolding movement of components such as the bottom tube 5 to be affected.

[0027] In order to solve the above problems, Figure 2 , Figure 4 , Figure 5 , Fig.10 , Fig.11 and Fig.12 As shown, the connecting tube 36 extending to the front end of the rectangular tube 3 and rotatably connected to the rectangular tube 3 is installed on the middle part of the front end of the rectangular frame 33. Through the connecting tube 36, on the one hand, the rectangular frame 33 is rotatably connected to the rectangular tube 3, and on the other hand, an installation space is provided for the second elastic member 35 and other components. The second elastic member 35 is installed on the inner rear wall of the connecting tube 36, and the front end surface of the round rod 37 arranged at the front end of the second elastic member 35 is overlapped with the front end surface of the connecting tube 36. The second elastic member 35 is used to make the round rod 37 and the connecting tube 36 movably connected. The second elastic member 35 can be a spring. An operating plate 31 located inside the second straight tube 82 and attached to the front end of the rectangular tube 3 is installed on the front end of the round rod 37. The round rod 37 can be rotated by the operating plate 31. A plurality of clamping strips 361 arranged along the length direction of the connecting tube 36 and located outside the second elastic member 35 are equidistantly installed on the inner wall of the connecting tube 36. A plurality of clamping grooves 371 extending to the rear end of the round rod 37 and slidably connected to the outer ends of the clamping strips 361 are formed on the outer end surface of the round rod 37. The clamping grooves 371 are used in conjunction with the clamping strips 361 to clamp the round rod 37 and the connecting tube 36. The front end surface of the operating plate 31 is recessed backward to form two recessed holes 311 penetrating the operating plate 31. Two fixing rods 38 located on the left and right sides of the connecting tube 36 and in the recessed holes 311 are symmetrically arranged on the front end of the rectangular tube 3. The recessed holes 311 and the fixing rods 38 are used in conjunction with each other to restrict the installation between the operating plate 31 and the rectangular tube 3.

[0028] When in use, the operating panel 31 is first held and pulled forward, so that the round rod 37 moves toward the front end along the connecting tube 36, and the second elastic member 35 is stretched to generate elastic force, and the concave hole 311 and the fixing rod 38 are separated. Then, the operating panel 31 is rotated 180°, so that the round rod 37 is rotated, and the connecting tube 36 is rotated under the cooperation of the clamping strip 361 and the clamping groove 371, so that the rectangular frame 33 and the first magnetic plate 32 are rotated 180° with the assistance of the rotating shaft 34, so as to complete the mechanical storage or unfolding of the bottom tube 5 and other components. Then the operating plate 31 is released, and under the elastic force of the second elastic member 35, the round rod 37 will move backward along the connecting tube 36, so that the operating plate 31 will move backward and fit with the rectangular tube 3 again, so that the fixing rod 38 will be reinserted into the recessed hole 311, and the operating plate 31 and the rectangular tube 3 will be re-restricted and installed, so as to realize the convenient conversion operation of the magnetic pole of the first magnetic plate 32, and effectively ensure the stability of the first magnetic plate 32 after the conversion, so that an effective force is formed between the first magnetic plate 32 and the second magnetic plate 42, so that the bottom tube 5 and other components can be effectively stored or unfolded.

[0029] Embodiment 4:

[0030] During the use of the device, the support bracket 7 is first unfolded to complete the installation of the total station body 1, and then the total station body 1 is leveled, and then the total station body 1 is used for surveying. When the survey is completed, the leveling structure is first stored, and then the support bracket 7 is stored, and then the device is carried, which results in more operating procedures for the device.

[0031] In order to solve the above problems, Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 7 As shown, the transverse parts of the three L-shaped frames 51 located on the inner side of the support bracket 7 are equidistantly installed on the outer end of the bottom tube 5, and the support arm 71 is movably installed on the upper side of the vertical part of the L-shaped frame 51 facing the outer end, and the other end of the support arm 71 is movably arranged on the lower side of the inner end of the support bracket 7. The L-shaped frame 51 and the support bracket 7 are movably connected through the support arm 71, and the three support arms 71 are arranged in a conical structure that is narrow at the top and wide at the bottom.

[0032] During the downward movement of the bottom tube 5, the three L-shaped frames 51 will move downward synchronously, thereby causing the support arm 71 to move downward inward, thereby causing the support arm 71 to move outward, thereby causing the support bracket 7 to expand outward. During the upward movement of the bottom tube 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 to be retracted, thereby achieving linkage between the up and down movement of the bottom tube 5 and the retraction and expansion movement of the support bracket 7, effectively reducing the operating procedures.

[0033] A method for using a construction site survey device comprises the following steps: The first step is to carry and place the survey device to a suitable position on the construction site, and then use the operating panel 31 to rotate the first magnetic plate 32, so that the first magnetic plate 32 and the second magnetic plate 42 are arranged to repel each other; 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 moving the bottom cylinder 5 downward, and simultaneously moving the multiple inverted U-shaped rods 6 downward, thereby moving the second piston 61 downward, and transporting the gas in the second straight cylinder 82 to the first straight cylinder 8 through the U-shaped tube 81, thereby moving the first piston 23 upward, thereby moving the ejector rod 22 upward and contacting the lower end of the total station body 1. When the lower end of the bottom cylinder 5 contacts the construction base surface under the repulsive force, the multiple ejector rods 22 will lift the total station body 1 at multiple points, and make the total station body 1 parallel to the construction base surface; The third step is to start the total station body 1, and perform centering, rough leveling and fine leveling operations on the total station body 1 to complete the surveying operation.

[0034] Although this specification is described according to implementation modes, not every implementation mode includes only one independent technical solution. This description of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment may also be appropriately combined to form other implementation modes that can be understood by those skilled in the art.
