DETAILED DESCRIPTION

[0054] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0055] like Figures 1-9 As shown, the present invention provides a construction engineering measurement device, comprising a connecting base 1, a supporting leg 2 being provided at the bottom of the connecting base 1, a clamping mechanism 5 being installed on the top of the clamping mechanism 5, and a measuring instrument 3 being assembled on the top of the clamping mechanism 5, the connecting base 1 comprising a fixed base 101 and an adjustable base 102;

[0056] The clamping mechanism 5 is installed on the top of the adjustment base 102, the support leg 2 is rotatably connected to the bottom periphery of the fixed base 101, and the adjustment base 102 is spherically sleeved on the outer side of the fixed base 101;

[0057] The fixed base 101 is provided with an adjustment ball 701 which is concentric with the adjustment base 102 and contains water. The outer side of the adjustment ball 701 extends from the bottom center of the fixed base 101 and is installed with a receiving rod 705. The receiving rod 705 is provided with a plurality of detachable counterweights 6.

[0058] The outer side of the adjusting ball 701 extends from the top center of the fixed base 101 and is connected to the center of the bottom inner side of the adjusting base 102;

[0059] An inner connecting rod 702 is installed on the inner wall of the regulating ball 701 , and a floating block 703 half-submerged under the water surface is installed at the bottom end of the inner connecting rod 702 .

[0060] 701 is in a horizontal position, and the adjusting ball 701 is in a horizontal position.

[0061] At the same time, when the supporting tripod 2 and the fixed base 101 are in a tilted state, the horizontal plane in the adjusting ball 701 is always in a horizontal state. When the adjusting ball 701 is in the automatic adjustment process just started, the offset of the adjusting ball 701 causes the relative position of the floating block 703 and the horizontal plane to change, so that the part of the floating block 703 immersed under the water surface is changed. At this time, since the buoyancy of each part of the floating block 703 is different, under the action of the buoyancy, the floating block 703 tends to the stable state of the initial state. Due to the spherical design of the adjusting ball 701, the floating block 703 returns to the initial state to drive the measuring instrument 3 to a horizontal state. Therefore, through this dual automatic level adjustment method, the measuring instrument 3 can automatically adjust the level, effectively increasing the strength and accuracy of the level adaptive adjustment.

[0062] Based on the above, the detachable counterweight block 6 can freely change the gravity pulling down the receiving rod 705, so as to adaptably adjust according to the model and gravity of the measuring instrument 3, thereby avoiding the inconvenience of carrying caused by the excessive weight of the counterweight block 6.

[0063] like Figures 1-9 As shown, compared with the previous embodiment, the difference is that the inner wall of the regulating ball 701 is installed with multiple distance detectors 10 for monitoring the distance from the water surface;

[0064] The top of the fixed base 101 and the inner bottom of the adjusting base 102 have a cavity, and a plurality of adjusting telescopic assemblies 9 are arranged in the cavity for adjusting the adjusting base 102;

[0065] The top end and the bottom end of the adjusting telescopic assembly 9 are connected to the adjusting base 102 and the fixed base 101 in a spherical manner.

[0066] It should be noted that in the adjusting process, the horizontal plane is always horizontal and is not affected by the friction between the adjusting ball 701 and the outside. When the measuring instrument 3 is in a horizontal state, the distance between the distance detector 10 and the horizontal plane is the same, so that the distance between the distance detector 10 and the horizontal plane can be determined to obtain the judgment result of whether the measuring instrument 3 is in a horizontal state. Through the comparison and calculation of the distances between the plurality of distance detectors 10 and the horizontal plane, the inclination angle and the inclination direction of the measuring instrument 3 can be obtained. Then, through the adjustment of the plurality of adjusting telescopic assemblies 9, the adjusting base 102 can be deflected in the opposite direction, so that the adjusting base 102 can be deflected to make the measuring instrument 3 in a horizontal state.

[0067] Based on the above, the adjusting telescopic assembly 9 is connected to the adjusting base 102 and the fixed base 101 in a spherical manner, so that the adjusting telescopic assembly 9 can adaptively rotate, and thus does not hinder the adaptive adjustment of the adjusting ball 701. The adaptive adjustment of the adjusting ball 701 ensures that there is 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 assembly 9 comprises 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 pipe 906, and a first rotating ball 907.

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

[0070] The bottom end of the first fixed seat 901 is sleeved with the first rotating ball 907, and the top end of the second fixed seat 904 is sleeved with the 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 with the telescopic sleeve 902, and the outer side of the second rotating ball 905 extends from the top of the second fixed seat 904 and is connected with the telescopic plug rod 903. The telescopic sleeve 902 is slidably sleeved on the outer side of the telescopic plug rod 903.

[0072] The telescopic sleeve 902 is externally provided with an air pipe 906 in communication with the inside of the telescopic sleeve 902, and the air pipe 906 is externally provided with an air pump.

[0073] It should be noted that in the embodiment, it is noted that the first rotating ball 907 and the second rotating ball 905 can be in spherical movement in the first fixed seat 901 and the second fixed seat 904, and 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 be rotated at multiple angles to adapt to horizontal adjustment at different angles.

[0074] Based on the telescopic sleeve 902 sleeved on the outside of the telescopic plug rod 903 and capable of forming a closed space in the telescopic sleeve 902, the air pump can charge and discharge air to the closed space in the telescopic sleeve 902 through the air pipe 906, so that the telescopic sleeve 902 and the telescopic plug rod 903 can move relatively, and here, the air supply is used to control the movement distance between the telescopic sleeve 902 and the telescopic plug rod 903, so that the movement distance between the telescopic plug rod 903 and the telescopic sleeve 902 is more accurately controlled.

[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 knob 603, and a spring 604.

[0076] The bottom end of the receiving rod 705 is provided with a tray;

[0077] The counterweight body 601 is provided with a straight groove, the receiving rod 705 is in the straight groove, the limiting semicircular ring 602 is rotationally connected in the counterweight body 601 and can be rotated into the straight groove to contact the receiving rod 705, and the control knob 603 is rotationally connected to the outside of the counterweight body 601 and connected to the end of the limiting semicircular ring 602.

[0078] The control knob 603 is connected with the spring 604 which drives the limiting semicircular ring 602 to be in the straight groove.

[0079] It should be noted that in the embodiment, the tray at the bottom of the receiving rod 705 can support the counterweight 6;

[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 limiting semicircular ring 602 is rotated into the straight groove, an annular structure surrounding the outside of the receiving rod 705 is formed, which can clamp the receiving rod 705, so that the counterweight body 601 can be stably installed on the receiving rod 705.

[0081] Based on the above, by rotating the control knob 603 relative to the counterweight body 601, then driving the limiting semicircle ring 602 to rotate, then making the limiting semicircle ring 602 rotate to completely open or close the straight slot, and under the action of the spring 604, the control knob 603 can drive the limiting semicircle ring 602 to always be in the state of closing the straight slot, 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 comprises a clamping connecting plate 501, a clamping drive ring 502, a clamping block 503, a positioning arc block 506, and a fixed ring 507.

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

[0084] The positioning arc block 506 is circumferentially arranged and installed on the outer periphery of the top of the clamping connecting plate 501, the fixed ring 507 is installed on the top of the positioning arc block 506 by bolts, and the clamping drive ring 502 is between the clamping connecting plate 501 and the fixed ring 507, and is sleeved on the outside of the positioning arc block 506;

[0085] The clamping block 503 is vertically slidingly connected to the bolt 508, and the outside of the clamping block 503 is threadedly connected to the inside of the clamping drive ring 502;

[0086] The clamping block 503 is L-shaped, and the top end of the clamping block 503 protrudes from the fixed ring 507 and presses down the measuring instrument 3.

[0087] It should be noted that in this embodiment, by screwing the clamping drive ring 502, the clamping drive ring 502 is rotated at a fixed position between the clamping connecting plate 501 and the fixed ring 507, and under the driving of the rotation of the clamping drive ring 502, the clamping block 503 can move up and down, and during the downward movement of the clamping block 503, the part of the clamping block 503 protruding from the fixed ring 507 can press down 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 down 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 the clamping mechanism 5, the difference is that the clamping mechanism 5 further comprises a suction cup 504 and an inner transmission plate 505.

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

[0091] The middle of the fixing ring 507 is provided with a circular hole, and the top of the fixing ring 507 is provided with a suction cup 504 which can be in contact with and sealed with the bottom of the measuring instrument 3.

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

[0093] It should be noted that in this embodiment, a sealed space is formed between the suction cup 504 and the bottom of the measuring instrument 3, and a negative pressure adsorption effect can be generated through the negative pressure between the spaces, so that the measuring instrument 3 can be adsorbed on the top of the fixing ring 507, and the installation of the measuring instrument 3 is more stable and firm.

[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 to move downward, and since the bottom of the suction cup 504 is pressed by the measuring instrument 3, the space between the middle of the suction cup 504 and the measuring instrument 3 becomes larger to form a negative pressure for adsorbing the measuring instrument 3.

[0095] As shown in Figures 1-9 Compared with the previous embodiment of the clamping mechanism 5, the difference is that the clamping mechanism 5 further comprises a latch 508.

[0096] The latch 508 is installed on the bottom surface of the clamping block 503 extending from the end of the fixing ring 507.

[0097] The bottom of the measuring instrument 3 is provided with a mounting plate 301, the outer side of the mounting plate 301 is provided with an ear groove, the size of the ear groove is larger than that of the clamping block 503, the ear groove can be in contact with the top of the fixing ring 507 through the clamping block 503, and the outer side of the mounting plate 301 can be in contact with the inner side of the clamping block 503.

[0098] The latch 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 in contact with the fixing ring 507 through the clamping block 503 when the mounting plate 301 is in contact with the fixing ring 507, and then the mounting plate 301 is rotated to displace the ear groove, so that the clamping block 503 can be in contact with the top of the mounting plate 301 to achieve the clamping effect. After the clamping block 503 clamps the mounting plate 301, the latch 508 can be inserted into the mounting plate 301 to lock the position of the mounting plate 301, so as to avoid the position deviation of the mounting plate 301, thereby making the installation of the measuring instrument 3 more stable.

[0100] Further, the outer side of the adjusting ball 701 is provided with a vertical rod, 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 to the center of the top of the clamping connecting plate 501.

[0101] It should be noted that in this embodiment, the locking of the positioning bolt 704 enables the adjusting ball 701 to be adjusted synchronously with the adjusting base 102 through the vertical rod.

[0102] As shown in the drawings, compared with the previous embodiment, the difference lies in that the support foot 2 comprises a connecting piece 201, a sliding rod 202, a sliding block 203, a locking bolt 204, an extension rod 205, and a support block 206. Figures 1-9

[0103] The connecting piece 201 is hinged to the outer side of the fixed base 101, the end of the connecting piece 201 is provided with opposite sliding rods 202, the sliding rods 202 are slidably connected with a sliding block 203, the end of the sliding block 203 is provided with an extension rod 205 which is in abutment with the sliding rod 202, and the end of the extension rod 205 is provided with an inner-arc-shaped support block 206.

[0104] The outer side of the sliding block 203 is threadedly connected with a locking bolt 204 which is in abutment with the sliding rod 202.

[0105] It should be noted that in this embodiment, the sliding limitation of the sliding block 203 enables the extension rod 205 to slide relative to the sliding rod 202, so as to adjust the length of the support foot 2 and adapt to different observation heights, and the position of the extension rod 205 and the sliding rod 202 after adjustment can be locked through the screwing of the locking bolt 204.

[0106] Further, the side of the measuring instrument 3 is provided with a PLC controller 4 which is electrically connected with the air pump and the distance detector 10.

[0107] It should be noted that in this embodiment, the PLC controller 4 receives the distance information transmitted by the distance detector 10 and forms a control instruction for controlling the air pump, so as to control the adjusting telescopic assembly 9 to adjust the adjusting base 102, so that the measuring instrument 3 remains horizontal.

[0108] In summary, when the building engineering technical measuring device is used, the support foot 2 is rotated to be opened for support, the extension rod 205 and the sliding rod 202 can be relatively extended through the relative sliding of the sliding block 203, the length adjustment effect of the support foot 2 is realized, and the sliding rod 202 and the extension rod 205 after adjustment can be locked through the locking bolt 204.​

[0109] When the tilt condition occurs, the adjusting ball 701 rotates relative to the fixed base 101 under the action of the gravity of the counterweight 6, so that the receiving rod 705 is always in the vertical state, and the water surface in the adjusting ball 701 is always kept horizontal in the tilt state. At this time, the position of the float 703 relative to the horizontal surface changes, and under the action of the buoyancy, the float 703 returns to the initial semi-submerged state, so that the receiving rod 705 can be in the vertical state. Through the transmission of the adjusting base 102, the measuring instrument 3 can always be in the horizontal state;

[0110] The distance between the distance detector 10 and the horizontal surface in the adjusting ball 701 is detected to determine whether the measuring instrument 3 is in the horizontal state. When the distances between all the distance detectors 10 and the horizontal surface are the same, the measuring instrument 3 is in the horizontal state. The inclination of the measuring instrument 3 is determined by the distance between the distance detector 10 and the horizontal surface;

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

[0112] Although the embodiments of the present application have been shown and described, it can be understood by those skilled in the art that various changes, modifications, replacements and variations can be made to the embodiments without departing from the principles and spirits of the present application, and the scope of the present application is defined by the appended claims and their equivalents.
