Description

A verticality detection tool

Technical Field

The utility model relates to the technical field of detection equipment, in particular to a verticality detection tool.

Background Art

In the fields of building, pipeline, bridge construction, etc., the verticality between the construction object and the horizontal ground is an important indicator to measure the construction quality. At present, the total station (or theodolite) and plumb line detection are generally used for the verticality detection of engineering structures. The defects of the above technology are: the total station (or theodolite) requires a stable and reliable platform to set up the instrument, which is affected by the line of sight conditions and is expensive; the plumb line method detection needs to be detected at the corner of the structure or on the side in the direction of the vertex inclination. The side opposite to the vertex inclination direction cannot be detected, and it needs to be measured with a ruler, which has a large error. Although the precise verticality measuring instruments on the market have high accuracy, they are technically difficult, are almost not produced in China, and are sold at a high price, so they are not popular. In order to solve the above problems, our company proposes a new verticality detection tool.

Utility Model Content

The utility model provides a verticality detection tool to solve the problem that the existing verticality detection tool cannot detect the side opposite to the inclination direction of the vertex when measuring the side of the structure.

In order to solve the above problems, the technical solution adopted by the utility model is as follows: a verticality detection tool, including a first frame, a second frame, and a measuring rod line, the first frame is parallel to the second frame, the measuring rod line is vertically connected between the opposite surfaces of the first frame and the second frame, a weight line is connected to the end of the first frame connected to the measuring rod line, and a plumb bob is connected to the lower end of the weight line; the first frame and the second frame are respectively provided with a transverse section and a vertical section, each frame has at least three transverse sections, and the transverse sections on each frame are perpendicular to the vertical sections, the transverse sections are arranged at intervals along the length of the vertical sections, and each transverse section is slidably connected with a retractable rod, and the top surface of each transverse section is respectively provided with a scale line, and each rod is provided with a pointer that can point to the scale line, and the transverse section is provided with a locking member that can lock the sliding distance of the rod, and the first frame and the second frame are respectively provided with a level.

The basic principle of this scheme is: when measuring, first center the bubble of the level on the first frame to keep the first frame horizontal, and adjust the rods (auxiliary rods) in the left and right transverse sections to make their readings consistent to ensure perpendicularity to the vertical plane, lock the left and right auxiliary rods, and record the reading of the middle rod (measuring rod) of the first frame. Let the measuring rod line droop naturally, and similarly, center the bubble of the level on the second frame, push the second frame horizontally toward the measuring surface, make the measuring rod line coincide with the weight line, and at the same time adjust the rods (auxiliary rods) in the left and right transverse sections on the second frame to make their readings consistent, lock the left and right auxiliary rods, and record the reading of the middle rod (measuring rod) of the second frame. The difference between the readings of the upper and lower measuring rods is the building inclination value.

The beneficial effect of this solution is that when the existing verticality detection tool measures the side of the structure, the side opposite to the inclination direction of the vertex cannot be detected. This solution sets up two upper and lower parallel first frames and second frames, uses the measuring rod line between the frames as an auxiliary line, and uses the plumb line as a reference line to achieve rapid measurement of the angle of the inclined surface. The retractable rods on the two frames can adapt to the inclined surfaces on both sides of the inclined building, so that both acute angles and obtuse angles can be measured. It has a simple structure, is easy to use, and can measure verticality quickly and efficiently.

Furthermore, the level includes a tube level and a circular level. The tube level is respectively arranged on the top surface of the vertical section of the first frame and the second frame, and the circular level is respectively arranged on the top surface of the middle horizontal section of the first frame and the second frame. The tube level is used to preliminarily adjust the level of the vertical section, and the circular level is used to adjust the level of the entire frame.

Furthermore, a spring is connected between one end of the rod located in the transverse section and the vertical section, so that the extension and retraction of the rod can be realized by the spring.

Furthermore, the ends of each rod away from the transverse section are processed into hemispherical surfaces, so as to facilitate the rod to contact the inclined surface to be measured.

Further, the locking member includes locking bolts, which are respectively threadedly connected and penetrate the bottom wall of the transverse section, and the end of the locking nut can conflict with the side wall of the rod in the transverse section. The auxiliary rod after leveling can be locked to facilitate reading of the measuring rod.

DETAILED DESCRIPTION

The following is further described in detail through specific implementation methods:

The figure marks in the drawings of the specification include: first frame 1, second frame 2, horizontal section 3, vertical section 4, tube level 5, circular level 6, spring 7, measuring rod 8, auxiliary rod 9, measuring rod line 10, weight line 11, plumb bob 12, scale line 13, pointer 14, locking bolt 15.

The embodiments are basically as shown in Figures 1 to 2:

A verticality detection tool includes a first frame 1 and a second frame 2. The structures of the first frame 1 and the second frame 2 are shown in FIG2. The first frame 1 and the second frame 2 are both in the shape of a Chinese character "山". Taking the first frame 1 as an example, the first frame 1 includes a transverse section 3 and a vertical section 4. The transverse section 3 and the vertical section 4 are perpendicular to each other. There are three transverse sections 3, and the three transverse sections 3 are arranged at intervals along the length of the vertical section 4. A tube level 5 arranged along the length of the vertical section 4 is arranged on the middle top wall of the vertical end. The parallelism between the vertical section 4 and the ground can be observed through the tube level 5, so that the vertical section 4 can be ensured to be parallel to the ground through manual debugging.

The transverse section 3 is a hollow cylindrical structure, and scale lines 13 are set on the top wall of the transverse section 3. A rod is slidably connected in each transverse section 3. A spring 7 is built between one end of the rod located in the transverse section 3 and the frame. The spring 7 can automatically reset the rod after sliding in the transverse section 3.

The rods in the two farthest transverse sections 3 are auxiliary rods 9, and the rod in the middle transverse section 3 is a measuring rod 8. A circular level 6 is provided on the transverse section 3 of the measuring rod 8, through which the parallelism between the transverse section 3 and the ground can be observed, so that the frame can be adjusted to be parallel to the ground with reference to the circular level 6.

The first frame 1 is arranged parallelly above the second frame 2, and a measuring rod line 10 is arranged between the measuring rod 8 of the first frame 1 and the measuring rod 8 of the second frame 2. The measuring rod line 10 is perpendicular to the two measuring rods 8 respectively. A weight line 11 is connected to the top of the measuring rod line 10 connected to the measuring rod 8 of the first frame 1, and a plumb bob 12 is connected to the lower end of the weight line 11 to ensure that the weight line 11 is always perpendicular to the ground.

In this embodiment, the ends of the rods away from the outside of the transverse section 3 are processed into hemispherical surfaces, and transverse grooves are respectively opened on the top walls of the transverse sections 3. The transverse grooves penetrate the top walls of the transverse sections 3. A pointer 14 is fixed on the upper surface of each rod. The pointer 14 can follow the sliding of the rod, thereby cooperating with the scale on the transverse section 3 to indicate and read. In this embodiment, the 0 scale line 13 is located in the middle of the transverse section 3. When the spring 7 is in a natural state, the pointer 14 points to the 0 scale line 13.

In this embodiment, a locking bolt 15 is provided at the bottom end away from the opening of the transverse section 3. The locking bolt 15 is threadedly connected and vertically penetrates the bottom wall of the transverse section 3. After vertically extending upward into the transverse section 3, its end portion abuts against the bottom wall of the rod, so that the rod can be locked in the transverse section 3 by turning the locking bolt 15.

The specific implementation process is as follows:

Taking the measuring surface shown in Figure 1 as an example, when conducting measurement, the staff will hold the first frame 1 parallel to the ground, place the measuring rod 8 and the auxiliary rod 9 of the first frame 1 against the surface to be measured, and adjust the first frame 1 to keep it level by centering the bubble of the tube level 5 and the circular level 6 on the first frame 1.

Keep the readings of the two auxiliary rods 9 on the first frame 1 the same, and tighten the locking bolt 15 to lock the auxiliary rod 9. By making the scales of the auxiliary rod 91 and the auxiliary rod 92 consistent, the measuring rod 8 can be kept horizontal and perpendicular to the vertical plane to ensure measurement accuracy. Record the reading of the pointer 14 of the measuring rod 8 in the first frame 1 at this time.

The measuring rod line 10 droops naturally to lift the second frame 2 off the ground. Referring to the debugging method of the first frame 1, the bubbles of the tube level 5 and the circular level 6 are used to center the second frame 2. The auxiliary rod 9 of the second frame 2 is then pressed against the measuring surface. After ensuring that the pointers 14 of the two auxiliary rods 9 have the same readings, the second frame 2 is pushed horizontally toward the measuring surface. The measuring rod 8 and the auxiliary rod 9 are both contracted into the transverse section 3, so that the measuring rod line 10 coincides with the weight line 11. When the readings of the left and right auxiliary rods 9 are inconsistent, the frame is adjusted. After the readings of the left and right auxiliary rods 9 are consistent, the auxiliary rod 9 is locked, and the pointer 14 reading on the measuring rod 8 of the second frame 2 is read. The difference between the readings on the upper and lower measuring rods 8 is the inclination value of the building.

The above is only an embodiment of the utility model, and the common knowledge such as the known specific structure and characteristics in the scheme is not described in detail here. It should be pointed out that for those skilled in the art, several deformations and improvements can be made without departing from the structure of the utility model, which should also be regarded as the protection scope of the utility model, and these will not affect the effect of the implementation of the utility model and the practicality of the patent. The scope of protection required by this application shall be based on the content of its claims, and the specific implementation methods and other records in the specification can be used to interpret the content of the claims.
