Description

Technical Field

[0001] The present invention relates to a measuring rod, in particular to a verticality measuring rod for engineering quality inspection applied to the technical field of measuring devices. Background Art

[0002] A verticality measuring rod is a measuring tool that ensures the rod remains vertical through structural design or auxiliary devices. It is mainly used in fields such as engineering surveying and mapping, and water conservancy surveying. Engineering quality inspection is an important task to ensure the safety of existing, under-construction, and to-be-built construction projects. During the entire construction process, tests are carried out on the foundation, building materials, construction technology, and building structure related to the building.

[0003] The specification of Chinese Patent CN202410133731.7 discloses "A verticality detection device for construction projects". When the rangefinder moves upward, the rotating plate contacts the roof above. The rotating plate will rotate on the side of the rangefinder. Under the pressure of the rotating plate and the top plate, the rotating plate will rotate below the rangefinder. The rangefinder is located above, and the highest point can be detected. When moving downward, the rotating plate below will rotate upward to the upper part. The cleaning plate can clean the wall before the rangefinder detects. The wall can be cleaned as a whole before detection to ensure the detection accuracy. The specification of Chinese Patent CN202411238027.4 discloses "A movable verticality detection device for engineering quality inspection". A high-speed rotating turntable is used to resist external disturbances and provide a stable reference direction. Using laser reflection lenses and prisms, a laser beam is projected onto the surface of the object to be measured. The verticality is judged by comparing the deviation of the light band. The device uses conductive coils to transmit power and signals. The laser angle detection component corrects errors in real time. The permanent magnet adsorption method is convenient for installation. The controller realizes automatic operation and data processing, improving the detection efficiency and accuracy.

[0004] During the measurement process of traditional verticality measuring rods, the measuring rod needs to be transferred to various positions of the building. However, each transfer of the measuring rod requires a new round of vertical state calibration. The traditional calibration method requires waiting for the rod to adapt to verticality by gravity, and the calibration time is relatively long. Moreover, the calibrated rod lacks a fixing structure, and the vertical rod is prone to skew during subsequent measurement processes. The skewed rod then needs to wait for it to return to the vertical state, thus affecting the verticality measurement efficiency of engineering buildings. Summary of the Invention

[0005] Aiming at the above-mentioned prior art, the technical problem to be solved by the present invention is that a rod vertically by gravity is prone to skew during subsequent measurement processes, and the skewed rod needs to wait for it to return to the vertical state, thus affecting the verticality measurement efficiency of engineering buildings.

[0006] To solve the above problems, the present invention provides a verticality measuring rod for engineering quality inspection, which includes a spherical chamber base. A calibration sphere is movably connected inside the spherical chamber base. A support column is fixedly connected to the bottom of the spherical chamber base. A support groove is formed at the bottom of the calibration sphere. The support column is inserted and corresponding to the support groove, and the top end of the support column is spherical. The support groove is conical, and the top end of the support groove is spherical corresponding to the top end of the support column. A benchmark column is inserted into the top of the calibration sphere, and the benchmark column penetrates and extends out of the top end of the spherical chamber base;

[0007] A counterweight ring is fixedly embedded inside the lower opening of the support groove. An expansion hole is annularly formed inside the counterweight ring. An extension foot is inserted into the expansion hole. The bottom end of the extension foot contacts and corresponds to the inner wall of the spherical chamber base. An electromagnetic module is fixedly embedded at the bottom of the spherical chamber base. The electromagnetic module adsorbs and corresponds to the extension foot.

[0008] In the above verticality measuring rod for engineering quality inspection, the gravity self-adaptive vertical ability of the calibration sphere is enhanced through the counterweight ring, so as to realize the vertical calibration of the benchmark column. Subsequently, the inner wall of the spherical chamber base is supported by the extension foot, and the electromagnetic module is used to adsorb the extension foot and the calibration sphere, effectively improving the stability of the calibrated benchmark column and facilitating the subsequent verticality measurement operation of engineering buildings.

[0009] As a further improvement of the present application, the bottom end face of the extension foot is arc-shaped corresponding to the inner wall of the spherical chamber base, and both the extension foot and the counterweight ring are made of stainless steel material, effectively improving the quality of the extension foot and the counterweight ring, thereby lowering the center of the calibration sphere, facilitating the calibration sphere to quickly and stably benchmark the column, and facilitating the stable contact between the bottom end face of the extension foot and the inner wall of the spherical chamber base, effectively improving the placement stability of the calibration sphere.

[0010] As a further improvement of the present application, an electrostrictive tendon is fixedly connected between the outer top of the support groove and the top end of the extension foot. The electrostrictive tendon is made of electrostrictive material. The electrocontrolled expansion and contraction of the extension foot is realized by using the electrostrictive tendon, effectively reducing the influence of the expansion and contraction of the extension foot on the stability of the calibration sphere.

[0011] As a further improvement of the present application, an insulating pad is fixedly connected to the connection part between the electrostrictive tendon and the extension foot. The insulating pad is made of rubber material. The insulating effect between the electrostrictive tendon and the extension foot is effectively improved by using the insulating pad, and the impact force between the extension foot and the spherical chamber base is buffered.

[0012] As another improvement of the present application, a reference column body is threadedly connected to one end of the outside of the spherical chamber base. Group connection holes are formed at the top ends of the benchmark column and the reference column body. A group connection benchmark is inserted into the top of the group connection hole. By adding the group connection benchmark, the lengths of the benchmark column and the reference column body are extended, facilitating adaptation to buildings of different heights.

[0013] As another supplementary improvement of the present application, laser emitters are fixedly sleeved on the roots of the reference column and the comparison column body, and both the reference column and the comparison column body are made of transparent organic glass, transparent polycarbonate or transparent epoxy resin materials. The lasers emitted into the reference column and the comparison column body by the laser emitters are used to effectively improve the measurement ability of the reference column and the comparison column body in a dark environment.

[0014] As another supplementary improvement of the present application, lens modules are fixedly connected in sequence from top to bottom inside the reference column and the comparison column body. The output end of the laser emitter is vertically corresponding to the inner end of the lens module. The inner ends of multiple lens modules are sequentially and progressively extended into the reference column and the comparison column body from bottom to top. The lens modules are installed in an inclined manner, and the inclination degree of the lens modules increases sequentially from bottom to top. The lasers emitted into the reference column and the comparison column body are refracted by the lens modules to realize the lasers shooting into and out of the reference column and the comparison column body, so as to realize the laser projecting onto the surface of the building to be measured, and further effectively improve the surveying and mapping ability of the reference column and the comparison column body.

[0015] As another supplementary improvement of the present application, the comparison column body is composed of multiple column cylinders sleeved in sequence. The lens module is fixedly installed one-to-one with the column cylinder. By rotating and lifting the column cylinder, the laser emitted from the comparison column body is calibrated to intersect with the laser emitted from the reference column, which is convenient for collecting angle data through the state of the laser beam.

[0016] In summary, after the ball bin base is correctly and stably placed, the gravity adaptive vertical ability of the calibration sphere is enhanced through the counterweight ring, so that the calibration sphere covers the top of the support column through the support groove cover, that is, the calibration sphere always maintains a vertical state, thereby realizing the automatic vertical calibration of the reference column. The vertical calibration is fast and convenient. Subsequently, the extension feet in the telescopic hole extend outwards. The calibration sphere uses the extension feet to support the inner wall of the ball bin base, and then uses the electromagnetic module to adsorb the extension feet and the calibration sphere to fix the vertical state of the calibration sphere, effectively improving the stability of the calibrated reference column and facilitating the subsequent measurement operation of the verticality of the engineering building.

Insulating pad. Specific implementation manners

[0030] The following will make a detailed description of the two implementation manners of the present application with reference to the accompanying drawings.

[0031] The first implementation manner:

[0032] Figures 1 to 5Shown is a verticality measuring rod for engineering quality inspection, which includes a spherical chamber base 1. Inside the spherical chamber base 1, a calibration sphere 101 is movably connected. At the bottom of the spherical chamber base 1, a support column 102 is fixedly connected. At the bottom of the calibration sphere 101, a support groove 103 is opened. The support column 102 is inserted corresponding to the support groove 103, and the top end of the support column 102 is spherical. The support groove 103 is conical, and the top end of the support groove 103 is spherical corresponding to the top end of the support column 102. The contact point between the support column 102 and the support groove 103 is at the center of the spherical chamber base 1, so as to facilitate the calibration sphere 101 to move inside the spherical chamber base 1. A rod column 2 is inserted into the top of the calibration sphere 101, and the rod column 2 penetrates and extends out of the top end of the spherical chamber base 1;

[0033] When erecting the measuring rod, first place the spherical chamber base 1 correctly and stably in front of the building to be measured. Insert the rod column 2 into the top of the calibration sphere 101, and then gently shake the spherical chamber base 1 so that the calibration sphere 101 can slightly sway through the support groove 103 on the support column 102. Wait for the calibration sphere 101 to stop. At this time, the rod column 2 is in a vertical state under the influence of the gravity of the calibration sphere 101. By observing the building and the rod column 2, the verticality measurement work is realized.

[0034] Figures 4 to 7 Shown is that inside the lower opening of the support groove 103, a counterweight ring 3 is fixedly inlaid. Inside the counterweight ring 3, a telescopic hole 301 is annularly opened. The counterweight ring 3 is used to enhance the downward force of the calibration sphere 101. Inside the telescopic hole 301, an extension support leg 302 is inserted. The bottom end of the extension support leg 302 contacts the inner wall of the spherical chamber base 1 correspondingly. At the bottom of the spherical chamber base 1, an electromagnetic module 303 is fixedly inlaid. The electromagnetic module 303 adsorbs corresponding to the extension support leg 302. The bottom end surface of the extension support leg 302 is arc-shaped corresponding to the inner wall of the spherical chamber base 1. Both the extension support leg 302 and the counterweight ring 3 are made of stainless steel material, effectively improving the quality of the extension support leg 302 and the counterweight ring 3, thereby lowering the center of the calibration sphere 101, facilitating the calibration sphere 101 to quickly and stably support the rod column 2, and facilitating the bottom end surface of the extension support leg 302 to stably contact the inner wall of the spherical chamber base 1, effectively improving the placement stability of the calibration sphere 101;

[0035] After the calibration sphere 101 comes to rest, the extension leg 302 inside the telescopic hole 301 extends outwards at this time. The bottom end face of the extended extension leg 302 stably contacts the inner wall of the ball bin base 1, that is, the calibration sphere 101 is stably placed in the ball bin base 1. Subsequently, the electromagnetic module 303 generates a magnetic force to adsorb the extension leg 302, effectively improving the contact effect between the extension leg 302 and the inner wall of the bin base 1. At the same time, the extension leg 302 is magnetized, indirectly realizing the adsorption and fixation of the extension leg 302 and the counterweight ring 3, further improving the state stability of the calibration sphere 101. Compared with the previous state where the calibration sphere 101 was in a falling state, it is more stable, effectively improving the anti-interference ability of the benchmark column 2.

[0036] Figures 5 to 8 As shown, an electrostrictive tendon 304 is fixedly connected between the outer top end of the support groove 103 and the top end of the extension leg 302. The electrostrictive tendon 304 is made of electrostrictive material. The electrostrictive tendon 304 is used to realize the electro-controlled expansion and contraction of the extension leg 302, effectively reducing the influence of the expansion and contraction of the extension leg 302 on the stability of the calibration sphere 101. An insulating pad 305 is fixedly connected to the connecting part of the electrostrictive tendon 304 and the extension leg 302. The insulating pad 305 is made of rubber material. The insulating pad 305 is used to effectively improve the insulation effect between the electrostrictive tendon 304 and the extension leg 302, and buffer the impact force between the extension leg 302 and the ball bin base 1;

[0037] The electrostrictive tendon 304 made of electrostrictive material realizes the automatic expansion and contraction of the extension leg 302 in the telescopic hole 301, and is convenient for the synchronous extension and control of the extension length of the extension leg 302, effectively avoiding the uneven extension of the extension leg 302 from damaging the falling state of the calibration sphere 101. The insulating pad 305 made of rubber material effectively improves the insulation effect between the electrostrictive tendon 304 and the extension leg 302, and the insulating pad 305 made of rubber material has excellent buffering ability, which is convenient for buffering the impact force between the extension leg 302 and the ball bin base 1.

[0038] The second implementation method:

[0039] Compared with the first implementation method, a reference column 201 and a laser emitter 204 are mainly added. The specific added structure is as follows, and the rest of the structure is the same as that of the first implementation method.

[0040] Figure 1 and Figure 9It is shown that a reference cylinder 201 is threadedly connected to the outer end of the ball bin base 1. Group connection holes 202 are provided at the tops of the reference pole 2 and the reference cylinder 201. A group connection pole 203 is inserted into the top of the group connection hole 202. By adding the group connection pole 203, the lengths of the reference pole 2 and the reference cylinder 201 are extended, facilitating adaptation to buildings of different heights. Laser emitters 204 are fixedly sleeved at the roots of the reference pole 2 and the reference cylinder 201. Both the reference pole 2 and the reference cylinder 201 are made of transparent organic glass, transparent polycarbonate or transparent epoxy resin materials. The laser emitted into the reference pole 2 and the reference cylinder 201 by the laser emitter 204 is utilized to effectively improve the measurement ability of the reference pole 2 and the reference cylinder 201 in a dark environment;

[0041] By simultaneously erecting the reference pole 2 and the reference cylinder 201, the reference pole 2 corresponds to the vertical state of gravity, and the reference cylinder 201 corresponds to the vertical state placed on the ground. In the case of insufficient light, the laser emitter 204 emits laser into the reference pole 2 and the reference cylinder 201, thereby effectively improving the visibility of the reference pole 2 and the reference cylinder 201. By comparing the deviation between the reference pole 2 and the reference cylinder 201, it is convenient to intuitively and quickly predict the perpendicularity deviation, thereby effectively improving the accuracy of the measurement result.

[0042] Figures 9 to 11 It is shown that lens modules 205 are fixedly connected in sequence from top to bottom inside the reference pole 2 and the reference cylinder 201. The output end of the laser emitter 204 is vertically corresponding to the inner end of the lens module 205. The inner ends of multiple lens modules 205 sequentially extend into the reference pole 2 and the reference cylinder 201 from bottom to top. The lens module 205 is installed in an inclined manner, and the inclination of the lens module 205 increases sequentially from bottom to top. The laser emitted into the reference pole 2 and the reference cylinder 201 is refracted by the lens module 205, realizing the laser to be emitted and then enter the reference pole 2 and the reference cylinder 201, thereby realizing the laser to be projected onto the surface of the building to be measured, further effectively improving the surveying and mapping ability of the reference pole 2 and the reference cylinder 201. The reference cylinder 201 is composed of multiple column cylinders 206 sleeved in sequence. The lens module 205 is fixedly installed one-to-one with the column cylinder 35. By rotating and lifting the column cylinder 206, the laser emitted from the reference cylinder 201 is calibrated to the state of intersecting with the laser emitted from the reference pole 2, facilitating the acquisition of angle data through the state of the laser beam;

[0043] The laser beams that enter the reference column 2 and the reference column body 201 are refracted outward through the lens module 205, and the lens module 205 has the ability to shape and transform the light beam, that is, to disperse the originally beam-shaped laser into a planar state, so as to form a laser line on the building to be measured from the reference column 2 and the reference column body 201. The lens module 205 with an inclined angle setting enables the emitted laser line to break through the height limit of the reference column 2 and the reference column body 201, facilitating the mapping of the laser line on the overall performance of the building. Subsequently, by adjusting the telescopic rotation of the column barrel 35 that constitutes the reference column body 201, the laser line emitted from the reference column body 201 is adjusted to intersect with the laser line emitted from the reference column 2, thus facilitating the acquisition of angle data through the intersecting laser lines.

[0044] Combined with the current actual requirements, the above-described implementation manner adopted in this application, the scope of protection is not limited thereto. Within the scope of knowledge possessed by those skilled in the art, various changes made without departing from the concept of this application still fall within the protection scope of the present invention.
