High precision is required for pipe laying, and the pipes must maintain a certain verticality. Therefore, during construction, the verticality of the pipes must be verified to meet design requirements. Currently, this measurement is typically performed with a spirit level, where the centering of the bubble is observed to provide feedback on the verticality of the gas nozzle installation. This method fails to provide intuitive data on gas nozzle verticality deviations, and cannot provide an effective basis for later determination of whether verticality meets design requirements.

[0011] In a possible implementation, a lap portion for lap-jointing the bottom end of the nozzle is fixedly mounted on one end of the semicircular measuring piece, and the outer diameter of the lap portion is greater than the outer diameter of the arc portion.

[0012] In a possible implementation, a holding rod is fixedly mounted on the semicircular measuring piece, and the axis of the holding rod is arranged parallel to the axis of the arc-shaped portion of the semicircular measuring piece.

[0022] In order to make the technical problems, technical solutions and beneficial effects to be solved by the present invention more clearly understood, the present invention is further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0023] Please also refer to Figures 1 to 4 , the gas down-spout installation verticality calibration tool provided by the present invention is now described. The gas down-spout installation verticality calibration tool comprises a pipe cap 1, a lifting rope 2, a plumb line 3 and a semicircular measuring piece 4. A positioning column 11 coaxially arranged with the inner hole of the nozzle is fixedly mounted on one end of the pipe cap 1; one end of the lifting rope 2 is mounted on the pipe cap 1, the lifting rope 2 passes through the positioning column 11, and the lifting rope 2 is coaxially arranged with the positioning column 11; the plumb line 3 is fixedly mounted on the other end of the lifting rope 2, and is used to pull the lifting rope 2 to extend downward in the vertical direction; the semicircular measuring piece 4 comprises an arc-shaped portion that slides with the inner hole of the nozzle and a measuring portion for connecting to both ends of the arc-shaped portion, and a recessed hole for avoiding the lifting rope 2 is provided on the measuring portion, and the recessed hole is coaxially arranged with the arc-shaped portion.

[0024] Compared with the prior art, the verticality calibration tool for the gas nozzle installation provided in this embodiment is provided with a pipe cap 1, and a positioning column 11 is provided at one end of the pipe cap 1. The pipe cap 1 and the positioning column 11 are an integral structure and are integrally processed and formed using a lathe. The outer diameter of the pipe cap 1 is larger than the outer diameter of the positioning column 11, and the pipe cap 1 and the positioning column 11 are coaxially arranged. A lifting rope 2 is also connected to the pipe cap 1, and the connection between the lifting rope 2 and the pipe cap 1 is located at the axial position of the positioning column 11. A plumb line 3 is installed at the other end of the lifting rope 2. When the present application is in use, the pipe cap 1 is overlapped on the top of the nozzle, and the positioning column 11 is located inside the nozzle. The plumb line 3 extends downward through the interior of the nozzle under its own gravity, and the plumb line 3 is located below the nozzle. After waiting for the plumb line 3 to be still, use the semicircular measuring piece 4 to fit the inner wall of the bottom of the nozzle, and rotate the semicircular measuring piece 4 around the axis of the nozzle. When the distance between the axis of the lifting rope 2 and the semicircular measuring piece 4 is the largest, use a measuring ruler to measure the distance between the center of the lifting rope 2 and the axis of the give way hole on the semicircular measuring piece 4, so as to obtain the distance of the nozzle bottom tilted in the vertical direction, which can provide an effective basis for the subsequent nozzle verticality detection and ensure the construction quality on site.

[0025] In some embodiments, the cap 1 may be Figure 2 The structure shown. Figure 2 , a conical hole coaxially arranged with the positioning column 11 is provided on the top of the pipe cap 1, a limiting ball 21 is movably installed inside the conical hole, and the end of the lifting rope 2 is installed on the limiting ball 21. When the pipe cap 1 is installed on the nozzle, the outer diameter of the pipe cap 1 gradually decreases from top to bottom. A limiting ball 21 is also freely placed inside the pipe cap 1, and one end of the lifting rope 2 is installed on the limiting ball 21, so that the connection of the lifting rope 2 is always located at the bottom of the limiting ball 21. Through the design of the limiting ball 21 and the conical hole, the lifting rope 2 can extend downward along the axis direction of the positioning column 11. It is ensured that the connection point of the lifting rope 2 on the positioning column 11 is located at the axis of the positioning column 11, thereby ensuring the accuracy of the detection value below the nozzle.

[0026] In some embodiments, the above-mentioned limiting ball 21 can be used as follows Figure 2 The structure shown. Figure 2 The lifting rope 2 is provided through the limiting ball 21, and a connecting plate 22 is fixedly installed at the end of the lifting rope 2 for connecting to the surface of the limiting ball 21. The lifting rope 2 is provided through the limiting ball 21, and a connecting plate 22 is fixedly installed at the end of the lifting rope 2 to prevent the limiting rope from escaping from the limiting ball 21. The structure is simple and convenient for connecting the lifting rope 2 to the pipe cap 1.

[0027] Preferably, in this embodiment, a sleeve for installing the lifting rope 2 is provided on the side of the lap plate 22 away from the limiting ball 21. The lifting rope 2 is located inside the sleeve and is fixed inside the sleeve by squeezing the sleeve.

[0028] In some embodiments, the above-mentioned lap plate 22 can be made of Figure 2 The structure shown. Figure 2 The side of the lap plate 22 closest to the limiting ball 21 is a curved surface that matches the outer surface of the limiting ball 21. When the lap plate 22 is attached to the limiting ball 21, the inner side of the lap plate 22 is a curved surface. This not only helps to locate the lap plate 22 relative to the limiting ball 21, but also helps to locate the position of the lifting rope 2. When the lap plate 22 abuts the limiting ball 21, the length of the lifting rope 2 is aligned with the axis of the positioning ball. This ensures that the lifting rope 2 is always located at the center of the positioning column 11, ensuring the accuracy of subsequent measurements.

[0029] In some embodiments, the semicircular measuring member 4 may be used as follows: Figure 3 The structure shown. Figure 3One end of the semicircular measuring piece 4 is also fixedly installed with a lap joint 41 for lap-jointing to the bottom end of the nozzle, and the outer diameter of the lap joint 41 is larger than the outer diameter of the arc-shaped portion. The lap joint 41 is coaxially arranged with the semicircular measuring piece 4 and is an integrally formed structure with the semicircular measuring piece 4. When using the semicircular measuring piece 4 for measurement, the semicircular measuring piece is placed on the inner wall of the bottom end of the nozzle. The semicircular measuring piece 4 is rotated with the axis of the nozzle as the center. When the axial distance between the lifting rope 2 and the clearance hole on the semicircular measuring piece 4 becomes the maximum, the distance between the axis of the lifting rope 2 and the axis of the clearance hole is measured by using a measuring ruler. The setting of the lap joint 41 allows the lap joint 41 to overlap the bottom end of the nozzle when the semicircular measuring body is placed. Ensure the stability of the position of the semicircular measuring body placed inside the nozzle.

[0030] Specifically, in this embodiment, the size of the clearance hole on the semicircular measuring body is larger than the outer diameter of the lifting rope 2, thereby preventing the semicircular measuring body from colliding with the lifting rope 2 during measurement and causing the lifting rope 2 to shake.

[0031] Preferably, in this embodiment, the measuring portion on the semicircular measuring body includes two side surfaces set at an angle, the connection between the two side surfaces is located at the axis of the arc portion, and the angle between the two side surfaces away from the arc portion is an acute angle, thereby further ensuring the stability of the position of the semicircular measuring body when it is installed at the bottom of the nozzle.

[0032] Specifically, in this embodiment, both ends of the nozzle are flat and are arranged perpendicular to the axis of the nozzle.

[0033] In some embodiments, the semicircular measuring member 4 may be used as follows: Figure 3 The structure shown. Figure 3 A holding rod 42 is also fixedly mounted on the semicircular measuring member 4. The axis of the holding rod 42 is spaced parallel to the axis of the arc-shaped portion of the semicircular measuring member 4. When installing the semicircular measuring member 4 at the bottom of the nozzle, the operator holds the holding rod 42 on the semicircular measuring member 4, which facilitates operation. One end of the holding rod 42 extends through the semicircular measuring member 4 and is threadedly connected to the semicircular measuring member 4. A fastener is also threadedly connected to the semicircular measuring member 4, which is used to abut against the end of the semicircular measuring member 4 to secure the holding rod 42 to the semicircular measuring member 4.

[0034] In some embodiments, the handle bar 42 may be Figure 3 The structure shown. Figure 3One side of the handle 42 is provided with a side edge for a measuring ruler to abut against the handle 42 , and the width of the side edge is set along the radial direction of the arc-shaped portion. The side edge set along the radial direction of the arc-shaped portion on the handle 42 allows the measuring ruler to be abutted against the side edge when measuring dimensions with the measuring ruler. This not only facilitates the placement of the measuring ruler, but also facilitates the alignment of the measuring ruler along the radial direction of the arc-shaped portion when the measuring ruler is placed against the side edge, thereby facilitating the measurement of the distance between the lifting rope 2 and the axis of the clearance hole on the semicircular measuring piece 4.

[0035] Preferably, in this embodiment, a groove is formed in the middle of the handle bar 42, the side plate is located inside the groove, and the bottom of the groove and the side plate are perpendicular to each other, so that the measuring ruler can be placed between the side and the bottom of the groove.

[0036] In some embodiments, the above-mentioned plumb bob 3 can be used as follows Figure 4 The structure shown. Figure 4 Two partitions 31 are arranged on the plumb line 3 at intervals along the axial direction of the plumb line 3. The two partitions 31 form a winding groove for accommodating the lifting rope 2, and one of the partitions 31 is provided with a slot for clamping the lifting rope 2. The end of the plumb line 3 away from the lifting rope 2 is a conical structure, and the end of the plumb line 3 close to the lifting rope 2 is a cylindrical structure. Two partitions 31 are fixedly installed on the end of the plumb line 3 close to the lifting rope 2. The two partitions 31 are arranged in parallel at intervals to form a winding groove for placing the lifting rope 2. After the verification tool is used, the lifting rope 2 can be wound into the winding groove for storage to prevent the lifting rope 2 from getting knotted or tangled. At the same time, a slot is provided on one of the partitions 31. The width of the slot is slightly smaller than the outer diameter of the lifting rope 2 in the natural state, and a mounting hole for accommodating the lifting rope 2 is provided at the end of the slot close to the axis of the plumb line 3. The size of the mounting hole is larger than the width of the slot, so that the lifting rope 2 can be lowered in a free state and limited inside the mounting hole.

[0037] Preferably, in this embodiment, the partition 31 is provided with multiple slots, the length directions of which are all arranged radially along the bobbin 3. The slots are evenly spaced along the circumference of the bobbin 3. The hoisting rope 2 can be moved into the winding groove through the slots and wound therein, and then secured to the partition 31 through the remaining slots, preventing the hoisting rope 2 from escaping from the partition 31.

[0038] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent replacements and improvements made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
