Description

Technical Field

[0001] The utility model relates to the technical field of engineering detection, in particular to a verticality detection tool for engineering supervision. Background Art

[0002] Verticality detection is a key link in engineering supervision, and its importance is self-evident. However, the currently widely used verticality detection devices such as plumb lines have some obvious shortcomings during use. First, these devices need to wait for the plumb line to be completely still during the detection process, which takes a long time and undoubtedly reduces the detection efficiency. Second, these devices are often difficult to accurately measure the specific deviation results of verticality, which undoubtedly affects the accuracy and reliability of engineering supervision. In order to overcome these defects, it is necessary to improve and optimize the existing verticality detection devices.

[0003] A Chinese patent (CN215832735U) discloses a verticality detection device for engineering supervision. Specifically, the device is stably placed on a base plate to ensure a stable detection process. Then, the device is adjusted to a horizontal state through the horizontal and vertical level adjustment components. This is mainly achieved through the interaction between the adjustment wheel and the threaded rod, which pushes the connecting seat to move until the level bubble shows the level. Then, the detection component is used for detection. The detection support plate can adjust the angle, and the telescopic support plate can adjust the position according to the size of the object. Both together ensure a close fit with the object to be measured. Finally, the semicircular protractor fixed on the detection support plate is used to read the verticality deviation angle displayed by the scale line. The entire device is easy to operate and realizes fast and accurate verticality detection, providing strong support for engineering supervision.

[0004] The adjustment process of the device in the comparative document is relatively complicated. Although the horizontal adjustment of the device can be achieved through the horizontal and vertical adjustment components, the adjustment wheel needs to be operated multiple times during the adjustment process, making the entire adjustment process relatively cumbersome, which will affect the detection efficiency, especially at the construction site where time is tight; the protractor of the device is fixed on the detection support plate, which is not convenient for the staff to measure directly. Utility Model Content

[0005] In response to the above problems, a verticality detection tool for engineering supervision is provided, which includes a base plate placed on the ground, a measuring platform for placing a measuring device, a level bubble on the platform for confirming the horizontal plane, a level adjustment device for adjustment between the base plate and the measuring platform, and a fixing mechanism for fixing the measuring platform after adjustment. The measuring platform is provided with a first connecting plate; a parallel synchronous measuring frame is connected to the first connecting plate, and the synchronous measuring frame consists of a contact plate abutting against the wall, a hollow protractor for measuring angles, an angle indicator plate for auxiliary readings, and a second connecting plate and a third connecting plate for allowing the contact plate and the angle indicator plate to move synchronously.

[0006] Preferably, the horizontal adjustment device includes a bottom groove on the bottom plate and a bottom rolling ball located in the bottom groove. A measuring platform is fixedly connected to the bottom rolling ball. The horizontal adjustment device adjusts the measuring platform by placing the bottom rolling ball in the bottom groove.

[0007] Preferably, the fixing mechanism includes a fixing base provided on the bottom plate, a fixing rod passing through a through hole on the fixing base, a notch on the bottom groove for inserting the fixing rod, and a tension switching button for controlling whether the fixing rod abuts against the bottom rolling ball.

[0008] Preferably, the contact plate has a first protrusion and a fourth protrusion, the second connecting plate is provided with a first adapting groove and a second protrusion adapted to the first protrusion, the angle indicating plate is provided with a second adapting groove and a third protrusion adapted to the second protrusion, and in addition, the third connecting plate is provided with a third adapting groove adapted to the third protrusion and a fourth adapting groove adapted to the fourth protrusion.

[0009] Preferably, the third convex block is provided with a pointer, and the direction of the pointer is consistent with the long side direction of the rod body.

[0010] Preferably, there is a space in the middle of the hollow protractor for the pointer to pass through, a third adapting groove and a fifth protrusion are provided on the hollow protractor, and a fifth adapting groove adapted to the fifth protrusion is provided on the third connecting plate.

[0011] Compared with the prior art, the present invention has the following beneficial effects:

[0012] 1. The utility model achieves reading at a position away from the wall by moving the protractor away from the wall and adding an angle indicator plate, thereby avoiding the deviation caused by the eyes not looking directly at the protractor and ensuring the accuracy of the reading. Space is opened up for the pointer in the middle of the hollow protractor, and scales are set on both sides. The reading surface is transparent, so that when the scales on the two end surfaces coincide, the human eye can look directly at and read the most accurate reading, thereby improving the convenience and accuracy of reading.

[0013] 2. The design of the parallel synchronous measuring frame of the utility model enables the contact plate and the angle indicator plate to move synchronously, which is flexible and stable in operation and improves the measurement efficiency. The horizontal adjustment device uses the bottom rolling ball to roll in the bottom groove to adjust the measuring platform, so that the measuring platform can be quickly and accurately adjusted to a horizontal position.

[0014] 3. The utility model adopts a unique fixing mechanism, which controls the extension and retraction of the fixing rod to achieve the limit and release of the bottom rolling ball. It is similar to the mechanism of controlling the extension and retraction of the pen core by pressing the button on the top of the pen. It is easy and reliable to operate. The design of the fixing mechanism not only ensures the stability of the measuring platform in the horizontal position, but also facilitates the quick arrangement and storage of the tools after the measurement is completed.

DETAILED DESCRIPTION

[0024] In order to further understand the features, technical means, specific objectives and functions achieved by the present invention, the present invention is described in further detail below in conjunction with the accompanying drawings and specific implementation methods.

[0025] Reference Figures 1-8 : A verticality detection tool for engineering supervision, including a base plate 1 placed on the ground, a measuring platform 4 for placing a measuring device, a level bubble 5 on the platform for confirming the horizontal plane, a level adjustment device 2 for adjustment between the base plate 1 and the measuring platform 4, and a fixing mechanism 3 for fixing the measuring platform 4 after adjustment. The measuring platform 4 is provided with a first connecting plate 41; the first connecting plate 41 is connected to a parallel synchronous measuring frame 42, and the synchronous measuring frame consists of a contact plate 421 abutting against the wall, a hollow protractor 43 for measuring angles, an angle indicating plate 423 for auxiliary readings, and a second connecting plate 422 and a third connecting plate 424 for allowing the contact plate 421 and the angle indicating plate 423 to move synchronously.

[0026] If the protractor is provided on a contact plate 421 abutting the wall, the reading may cause deviation due to the eyes not looking directly at the protractor. To solve this problem, the present invention adopts a method of moving the protractor away from the wall and adding an angle indicator plate 423. The angle indicator plate 423 moves synchronously with the contact plate 421 abutting the wall through the second connecting plate 422 and the third connecting plate 424, so that the reading can be taken at a position away from the wall, ensuring the accuracy of the reading. The detection device is placed on the ground next to the wall to be measured. The measuring platform 4 is adjusted to a horizontal position by the level adjustment device 2 between the base plate 1 and the measuring platform 4 and the marking of the level bubble 5. At this time, the measuring platform 4 is fixed by the fixing device so that the measuring platform 4 is always in a horizontal position. Further, the contact plate 421 is operated to abut the wall to be measured, driving the angle indicator plate 423 that moves synchronously with it to mark the degree on the hollow protractor 43. At this time, the reading on the hollow protractor 43 is the required data, thereby completing the entire detection process.

[0027] Reference Figure 1-Figure 5 : The horizontal adjustment device 2 includes a bottom groove 21 on the base plate 1, a bottom rolling ball 22 located in the bottom groove 21, and a measuring platform 4 is fixedly connected to the bottom rolling ball 22. The horizontal adjustment device 2 adjusts the measuring platform 4 by placing the bottom rolling ball 22 in the bottom groove 21.

[0028] Place the detection tool on the ground through the base plate 1, then use the level bubble 5 on the measuring platform 4 to determine whether the measuring platform 4 is in a horizontal position. If the measuring platform 4 is not in a horizontal position, adjust the measuring platform 4 to a horizontal position through the level adjustment device 2 set between the base plate 1 and the measuring platform 4. The bottom rolling ball 22 is fixedly connected to the measuring platform 4 through a connecting rod. The bottom rolling ball can roll in the bottom groove 21, thereby driving the measuring platform 4 to rotate through the bottom rolling ball 22 until the measuring platform 4 is adjusted to a horizontal position.

[0029] Reference Figure 1-Figure 5 The fixing mechanism 3 includes a fixing base 31 provided on the bottom plate 1, a fixing rod 32 passing through a through hole on the fixing base 31, a notch 211 on the bottom groove 21 for inserting the fixing rod 32, and a tension switching button 33 for controlling whether the fixing rod 32 abuts against the bottom rolling ball 22.

[0030] When the measuring platform 4 is already in a horizontal position, press the tension switching button 33, and the fixing rod 32 will extend inwardly toward the position of the notch 211 on the bottom groove 21 until it abuts against the bottom rolling ball 22 to achieve a limiting effect. Then, further, when the measurement is completed, press the tension switching button 33 again and pull it outward from the notch 211 on the bottom groove 21 to release the limit on the bottom rolling ball 22. The tension switching button 33 controls the extension and retraction of the fixing rod 32 to achieve the limiting and releasing of the bottom rolling ball 22. This technical effect is similar to the mechanism of controlling the extension and retraction of the internal pen core by pressing the button on the top of the pen.

[0031] Reference Figure 6-Figure 8 : The contact plate 421 is provided with a first protrusion 4211 and a fourth protrusion 4212, the second connecting plate 422 is provided with a first adapting groove 4222 and a second protrusion 4221 adapted to the first protrusion 4211, the angle indicating plate 423 is provided with a second adapting groove 4231 and a third protrusion 4232 adapted to the second protrusion 4221, and in addition, the third connecting plate 424 is provided with a third adapting groove 4241 adapted to the third protrusion 4232 and a fourth adapting groove 4242 adapted to the fourth protrusion 4212.

[0032] By the cooperation of the first protrusion 4211 and the first adapting groove 4222, the first protrusion 4211 is connected to the second connecting plate 422; by the second protrusion 4221 and the second adapting groove 4231, the second connecting plate 422 is connected to the angle indicating plate 423; by the third protrusion 4232 and the third adapting groove 4241, the angle indicating plate 423 is connected to the third connecting plate 424; through the cooperation of the above-mentioned components, a parallel synchronous measuring frame 42 can be formed. In this structure, the second connecting plate 422 and the third connecting plate 424 are both kept parallel to the measuring platform 4, and the contact plate 421 and the angle indicating plate 423 are also kept parallel. In this way, when measuring the horizontal position, the third connecting plate 424 is also always in the horizontal position. After the contact plate 421 is in contact with the wall to be measured, the angle formed by the angle indicating plate 423 and the third connecting plate 424 is the required angle.

[0033] Reference Figure 6-Figure 8 : A pointer 4233 is provided on the third protrusion 4232, and the direction of the pointer 4233 is consistent with the long side direction of the rod body.

[0034] The angle can be read more directly through the pointer 4233, which speeds up the efficiency of reading the angle.

[0035] Reference Figure 6-Figure 8 : There is a space in the middle of the hollow protractor 43 for the pointer 4233 to pass through. The hollow protractor 43 is provided with a third adapting groove 4241 and a fifth protrusion 431, and the third connecting plate 424 is provided with a fifth adapting groove 4243 adapted to the fifth protrusion 431.

[0036] Through the third adapter slot 4241 on the hollow protractor 43, the center origin of the hollow protractor 43 coincides with the axis of the third protrusion 4232, and the pointer 4233 on the third protrusion 4232 can rotate within the hollow protractor 43. The space reserved for the pointer 4233 in the hollow protractor 43 has scales on both sides, and the reading side is transparent. When reading, when the scales on the two end surfaces coincide, it means that the human eye is looking straight ahead at this time. The result read at this time is the most accurate reading under the current conditions.

[0037] The above embodiments merely represent one or several implementations of the present invention. While the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the present invention. It should be noted that a person skilled in the art would be able to make various modifications and improvements without departing from the spirit of the present invention, and these modifications and improvements fall within the scope of protection of the present invention. Therefore, the scope of protection of the present invention shall be determined by the appended claims.
