Description

A building engineering technical measurement device Technical Field

[0001] This invention relates to the field of building engineering measurement technology, specifically to a building engineering measurement device. Background Technology

[0002] In construction engineering, it is often necessary to use construction engineering surveying instruments to measure the site conditions. Engineering surveying instruments are a type of measuring instrument used in the planning, design, construction, and operation management stages of engineering construction. They include various instruments for orientation, distance measurement, angle measurement, height measurement, mapping, and photogrammetry. They mainly include theodolites, levels, plane tables, distance measuring instruments, gyro theodolites, laser measuring instruments, cameras, measuring instruments, plotters, projectors, and other instruments.

[0003] In architectural design and engineering planning, on-site surveys are required. When using the instruments on-site, tripods are needed to support them. To ensure the accuracy of the test data, the instruments need to be leveled. However, the unevenness of the ground means that leveling is required every time the location is changed. This results in frequent and extensive leveling work, which is inefficient and can easily distract the staff. To address these issues, we propose a technical measurement device and method for architectural engineering. Summary of the Invention

[0054] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0055] As shown in Figures 1-9, the present invention provides a building engineering technology measuring device, including a connecting seat 1, a support bracket 2 at the bottom of the connecting seat 1, a clamping mechanism 5 at the top of the connecting seat 1, and a measuring instrument 3 at the top of the clamping mechanism 5. The connecting seat 1 includes a fixed base 101 and an adjusting base 102.

[0056] The clamping mechanism 5 is installed on the top of the adjusting base 102, the support bracket 2 is rotatably connected to the bottom outer periphery of the fixed base 101, and the adjusting base 102 is spherically sleeved on the outside of the fixed base 101.

[0057] The fixed base 101 is provided with an adjusting ball 701 that is concentric with the adjusting base 102 and contains moisture. The adjusting ball 701 extends out from the bottom center of the fixed base 101 and is equipped with a support rod 705. The support rod 705 is provided with multiple detachable counterweights 6.

[0058] The adjusting ball 701 extends outward from the top center of the fixed base 101 and connects to the center of the bottom of the adjusting base 102;

[0059] The inner wall of the regulating ball 701 is equipped with an inner connecting rod 702, and the bottom end of the inner connecting rod 702 is equipped with a float 703 that is partially submerged in water.

[0060] It should be noted that in this embodiment, when the top of the adjusting base 102 is in a horizontal state, the inner connecting rod 702 and the supporting rod 705 are both in a vertical state. At this time, the float 703 floats on the water surface and is in a semi-submerged state. The buoyancy of the float 703 is the same at all points, keeping it stably floating on the water surface. When the supporting leg 2 and the fixed base 101 are in an inclined state, the counterweight 6 pulls down the adjusting ball 701. At this time, the supporting rod 705 rotates around the adjusting ball 701. The adjusting ball 701 adopts a spherical movement mode, which can form free adjustment at multiple angles, making the adjustment of the measuring instrument 3 more convenient and quick, and more adaptable. The adjusting ball 701 is always in a horizontal state. At this time, the adjusting ball 701 deflects under the pull of the supporting rod 705, thus driving the adjusting base 102 to deflect, so that the measuring instrument 3 on the top of the adjusting base 102 can automatically adjust to a horizontal state.

[0061] Meanwhile, when the support bracket 2 and the fixed base 101 are tilted, the horizontal plane inside the adjusting ball 701 remains horizontal. However, during the automatic adjustment process of the adjusting ball 701, the offset of the adjusting ball 701 causes the float 703 to change relative to the horizontal plane, thus changing the part of the float 703 submerged below the water surface. At this time, because the buoyancy of each part of the float 703 is different, the float 703 tends to the initial stable state under the action of buoyancy. Due to the spherical design of the adjusting ball 701, the float 703 returns to the initial state to drive the measuring instrument 3 to be horizontal. Therefore, through this dual automatic horizontal adjustment method, the measuring instrument 3 can automatically adjust the level, effectively increasing the strength and accuracy of the adaptive horizontal adjustment.

[0062] Based on the above, the detachable counterweight 6 allows for free adjustment of the force exerted on the support rod 705, adapting to the model of the measuring instrument 3 and the gravity, thus avoiding inconvenience caused by excessive weight of the counterweight 6.

[0063] As shown in Figures 1-9, the difference from the previous embodiment is that the inner wall of the regulating ball 701 is equipped with a plurality of distance detectors 10 for monitoring the distance to the water surface;

[0064] There is a cavity between the top of the fixed base 101 and the inner bottom of the adjusting base 102, and a plurality of adjusting telescopic components 9 for adjusting the adjusting base 102 are provided in the cavity.

[0065] The top and bottom ends of the adjustable telescopic component 9 are connected to the adjusting base 102 and the fixed base 101 by a spherical movable connection.

[0066] It should be noted that in this embodiment, during the adjustment process, since the horizontal plane is always horizontal, it will not be affected by the friction between the adjusting ball 701 and the external force. When the measuring instrument 3 is in a horizontal state, the distance between the distance detector 10 and the horizontal plane is the same. Therefore, the distance between the distance detector 10 and the horizontal plane can be used to determine whether the measuring instrument 3 is in a horizontal state. By comparing the distances detected by multiple distance detectors 10 and the horizontal plane and calculating the results, the tilt angle and tilt direction of the measuring instrument 3 can be obtained. Then, by adjusting multiple adjusting telescopic components 9, the adjusting base 102 can be pushed in the opposite direction to deflect, so that the adjusting base 102 can deflect and make the measuring instrument 3 in a horizontal state.

[0067] Based on the above, the adjusting telescopic component 9 is connected to the adjusting base 102 and the fixed base 101 by a spherical movable connection, which allows the adjusting telescopic component 9 to rotate adaptively, thus not hindering the adaptive adjustment of the adjusting ball 701. This ensures that the adjusting ball 701 can be adaptively adjusted while providing space for subsequent horizontal precision adjustment.

[0068] As shown in Figures 1-9, compared with the previous embodiment, the difference is that the adjusting telescopic component 9 includes a first fixed seat 901, a telescopic sleeve 902, a telescopic plug rod 903, a second fixed seat 904, a second rotating ball 905, an air tube 906, and a first rotating ball 907.

[0069] The first fixing seat 901 is mounted on the adjusting base 102, and the second fixing seat 904 is mounted on the fixing base 101;

[0070] The bottom end of the first fixed base 901 is fitted with a first rotating ball 907, and the top end of the second fixed base 904 is fitted with a second rotating ball 905.

[0071] The outer side of the first rotating ball 907 extends from the bottom of the first fixed seat 901 and is connected to a telescopic sleeve 902. The outer side of the second rotating ball 905 extends from the top of the second fixed seat 904 and is connected to a telescopic plug rod 903. The telescopic sleeve 902 is slidably sleeved on the outer side of the telescopic plug rod 903.

[0072] An air pipe 906 is installed on the outside of the telescopic sleeve 902 and is connected to the inside of the telescopic sleeve 902. An air pump is connected to the outside of the air pipe 906.

[0073] It should be noted that in this embodiment, the first rotating ball 907 and the second rotating ball 905 can move spherically inside the first fixed seat 901 and the second fixed seat 904. Through the movement of the first rotating ball 907 and the second rotating ball 905, the telescopic sleeve 902 and the telescopic plug rod 903 can rotate at multiple angles to adapt to different angles of horizontal adjustment.

[0074] Based on the fact that the telescopic sleeve 902 is sleeved on the outside of the telescopic plug rod 903 and can form a sealed space inside the telescopic sleeve 902, the air pump can charge and discharge air into the sealed space inside the telescopic sleeve 902 through the air pipe 906, so that the telescopic sleeve 902 and the telescopic plug rod 903 can move relative to each other. Here, the movement distance between the telescopic sleeve 902 and the telescopic plug rod 903 is controlled by air supply, so that the movement distance between the telescopic plug rod 903 and the telescopic sleeve 902 can be controlled more precisely.

[0075] As shown in Figures 1-9, this is a preferred embodiment of the counterweight 6, which includes a counterweight body 601, a limiting semicircular ring 602, a control element 603, and a spring 604.

[0076] A tray is installed at the bottom end of the receiving rod 705;

[0077] The counterweight body 601 has a through-hole straight groove, the receiving rod 705 is located in the straight groove, the limiting semicircular ring 602 is rotatably connected to the counterweight body 601 and can rotate into the straight groove to contact the receiving rod 705, and the control member 603 is rotatably connected to the outside of the counterweight body 601 and connected to the end of the limiting semicircular ring 602.

[0078] The control element 603 is connected to the inner wall of the counterweight body 601 by a spring 604 that drives the limiting semicircular ring 602 to be in the straight groove.

[0079] It should be noted that in this embodiment, the counterweight 6 can be supported by the tray at the bottom of the receiving rod 705.

[0080] The straight groove points from the outside of the counterweight body 601 to the center of the counterweight body 601, and the end of the straight groove is at the center of the counterweight body 601. When the semicircular ring 602 rotates into the straight groove, it can form a ring structure around the outside of the receiving rod 705, which has a clamping effect on the receiving rod 705, thereby enabling the counterweight body 601 to be stably installed on the receiving rod 705.

[0081] Based on the above, the control member 603 rotates relative to the counterweight body 601, thereby driving the limiting semicircular ring 602 to rotate. This allows the limiting semicircular ring 602 to rotate and fully open or close the straight groove. Under the action of the spring 604, the control member 603 can drive the limiting semicircular ring 602 to always be in the closed straight groove state, so as to ensure that the counterweight body 601 is stably installed on the receiving rod 705.

[0082] As shown in Figures 1-9, this is a preferred embodiment of the clamping mechanism 5, which includes a clamping connecting plate 501, a clamping driving ring 502, a clamping block 503, a positioning arc block 506, and a fixing ring 507.

[0083] The clamping connecting plate 501 is mounted on the top of the adjusting base 102 by bolts;

[0084] The positioning arc-shaped blocks 506 are arranged in a circumferentially spaced manner and installed on the outer periphery of the top of the clamping connecting plate 501. The fixing ring 507 is installed on the top of the positioning arc-shaped blocks 506 by bolts. The clamping drive ring 502 is located between the clamping connecting plate 501 and the fixing ring 507 and is sleeved on the outside of the positioning arc-shaped blocks 506.

[0085] The clamping block 503 is vertically slidably connected to the pin 508, and the outer side of the clamping block 503 is threadedly connected to the inner side of the clamping drive ring 502.

[0086] The clamping block 503 is L-shaped, and the top of the clamping block 503 extends out of the fixing ring 507 and presses down to lock the measuring instrument 3.

[0087] It should be noted that in this embodiment, by twisting the clamping drive ring 502, the clamping drive ring 502 is rotated in a fixed position between the clamping connecting plate 501 and the fixed ring 507. Driven by the rotation of the clamping drive ring 502, the clamping block 503 can move up and down. During the downward movement of the clamping block 503, the part of the clamping block 503 extending out of the fixed ring 507 can press down on the measuring instrument 3, thereby locking the installation of the measuring instrument 3.

[0088] Based on the above, the circumferentially arranged clamping blocks 503 enable the measuring instrument 3 to be circumferentially pressed and locked, thereby making the installation of the measuring instrument 3 more stable.

[0089] As shown in Figures 1-9, compared with the previous embodiment of clamping mechanism 5, the clamping mechanism 5 further includes a suction cup 504 and an inner transmission plate 505.

[0090] The outer side of the inner transmission plate 505 is connected to the inner side of the clamping block 503;

[0091] The fixing ring 507 has a through hole in the middle, and a suction cup 504 is installed on the top of the fixing ring 507 that can contact and seal with the bottom of the measuring instrument 3.

[0092] The bottom center of the suction cup 504 is connected to the top of the inner transmission plate 505 through a circular hole.

[0093] It should be noted that in this embodiment, a sealed space is created between the suction cup 504 and the bottom of the measuring instrument 3. The negative pressure between the spaces can produce a negative pressure adsorption effect, thereby allowing the measuring instrument 3 to be adsorbed on the top of the fixing ring 507, making the installation of the measuring instrument 3 more stable and secure.

[0094] Based on the above, during the downward movement of the clamping block 503, the inner transmission plate 505 moves downward together and pulls the middle of the suction cup 504 downward. Since the suction cup 504 is easily pressed by the bottom of the measuring instrument 3, the space between the middle of the suction cup 504 and the measuring instrument 3 gradually increases, so as to form a negative pressure to adsorb the measuring instrument 3.

[0095] As shown in Figures 1-9, compared with the previous embodiment of clamping mechanism 5, the difference is that the clamping mechanism 5 further includes a pin 508;

[0096] The pin 508 is installed on the bottom surface of the end of the clamping block 503 that extends out of the fixing ring 507;

[0097] The measuring instrument 3 has a mounting plate 301 at its bottom. The mounting plate 301 has an ear groove on its outer side. The ear groove has a diameter larger than the clamping block 503. The ear groove can contact the top of the fixing ring 507 through the clamping block 503, and the outer side of the mounting plate 301 can contact the inner side of the clamping block 503.

[0098] The pin 508 can be inserted into the mounting plate 301 from the top of the mounting plate 301.

[0099] It should be noted that, in this embodiment, the ear groove on the mounting plate 301 can be clamped by the clamping block 503. When the mounting plate 301 contacts the fixing ring 507, the mounting plate 301 is rotated, causing the ear groove to shift. This allows the clamping block 503 to move downward and contact the top of the mounting plate 301, thus achieving a clamping effect. After the clamping block 503 clamps the mounting plate 301, the pin 508 can be inserted into the mounting plate 301 to lock the position of the mounting plate 301, preventing the position of the mounting plate 301 from shifting, thereby making the installation of the measuring instrument 3 more stable.

[0100] Furthermore, a vertical rod is installed on the outer side of the adjusting ball 701, the top of the vertical rod is inserted into the center of the bottom of the clamping connecting plate 501, and a positioning bolt 704 is threadedly connected thereto, the positioning bolt 704 abutting against the center of the top of the clamping connecting plate 501.

[0101] It should be noted that, in this embodiment, the adjusting ball 701 can be adjusted synchronously with the adjusting base 102 by locking the positioning bolt 704.

[0102] As shown in Figures 1-9, compared with the previous embodiment, the difference is that the support frame 2 includes a connector 201, a sliding rod 202, a sliding block 203, a locking bolt 204, an extension rod 205, and a support block 206.

[0103] The connector 201 is hinged to the outside of the fixed base 101. The end of the connector 201 is equipped with opposing sliding rods 202. A sliding block 203 is slidably connected between the sliding rods 202. An extension rod 205 that fits against the sliding rod 202 is installed at the end of the sliding block 203. An inner arc-shaped support block 206 is installed at the end of the extension rod 205.

[0104] The outer side of the sliding block 203 is threaded with a locking bolt 204 that can abut against the sliding rod 202.

[0105] It should be noted that, in this embodiment, the sliding block 203 limits the sliding of the extension rod 205 to allow relative sliding between it and the sliding rod 202, thereby adjusting the length of its support leg 2 to accommodate observations at different heights. The locking bolt 204 can be tightened to lock the adjusted positions of the extension rod 205 and the sliding rod 202.

[0106] Furthermore, a PLC controller 4 is mounted on the side of the measuring instrument 3, and the PLC controller 4 is electrically connected to the air pump and the distance detector 10.

[0107] It should be noted that in this embodiment, the distance information transmitted by the distance detector 10 is received through the overall control of the PLC controller 4, and a control command for controlling the air pump is generated to control the adjusting telescopic component 9 to adjust the adjusting base 102 so that the measuring instrument 3 remains horizontal.

[0108] In summary, when using this construction engineering technical measurement device, rotating the support leg 2 allows the support leg 2 to open for support. Through the relative sliding block 203, the extension rod 205 and the sliding rod 202 can be extended relative to each other, thereby achieving the effect of adjusting the length of the support leg 2. The locking bolt 204 can lock the adjusted sliding rod 202 and the extension rod 205.

[0109] When tilting occurs, the counterweight 6 causes the adjusting ball 701 to rotate relative to the fixed base 101, keeping the receiving rod 705 vertical. Even when tilted, the water level inside the adjusting ball 701 remains horizontal. At this time, the float 703 changes position relative to the horizontal plane. Under the action of buoyancy, the float 703 is driven back to the initial semi-submerged state, thus keeping the receiving rod 705 vertical. Through the transmission of the adjusting base 102, the measuring instrument 3 can always remain horizontal.

[0110] The distance between the distance detector 10 and the horizontal plane inside the adjustment ball 701 is detected to determine whether the measuring instrument 3 is in a horizontal state. When all the distance detectors 10 are at the same distance from the horizontal plane, the measuring instrument 3 is in a horizontal state. The tilt of the measuring instrument 3 is determined by the distance between the distance detector 10 and the horizontal plane.

[0111] The air pump controls the air pressure inside the telescopic sleeve 902 through the air pipe 906, and then controls the extension distance between the telescopic sleeve 902 and the telescopic stopper 903. Through the cooperation between multiple telescopic sleeves 902 and telescopic stopper 903, the adjusting base 102 is adjusted, so that the measuring instrument 3 can be in a horizontal state.
