An arc surface B is provided on 204, and the center of the arc surface A of the lower retaining ring 202 and the center of the arc surface B of the upper retaining ring 204 are on the same straight line. The lower retaining ring 202 and the upper retaining ring 204 are also made of aluminum alloy, which meets the requirements of lightweight and high strength. Circular level steam drums are set in the lower retaining ring 202 and the upper retaining ring 204 respectively. The purpose of setting circular level steam drums in this position is to facilitate the auxiliary installation of water supply and drainage risers using only the lower retaining ring 202 and the upper retaining ring 204 in a narrow operating space. A readable circular level steam drum device 205 is sleeved on the lower upright 101. The readable circular level steam drum device 205 has a graduated circular level bubble installed on its inner side.

[0031] This utility model, through the setting of the correction component 2, when in use, pulls the upper upright 103 out from the lower upright 101. The specific extension length (height) depends on the installation height of the water supply and drainage riser in the use state. Then, the arc surface A of the lower retaining ring 202 and the arc surface B of the upper retaining ring 204 are evenly and tightly attached to the surface of the water supply and drainage riser. It should be remembered that the lower retaining ring 202 and the upper retaining ring 204 are simultaneously and tightly attached to the water supply and drainage riser. Then, according to the circular level bubble with numerical scale set on the lower upright 101 of the device, the deviation value of the water supply and drainage riser is taken.

[0032] As a preferred embodiment, it further includes a fastening assembly 3; the fastening assembly 3 is arranged on the verticality device body 1; wherein, the fastening assembly 3 includes an external threaded cylinder 301, an internal threaded cylinder 302, an elastic element 303, a pressing block 304, and a pressing groove 305; the external threaded cylinder 301 is fixedly connected to the end of the lower upright 101 away from the lower threaded block 201; the internal threaded cylinder 302 is slidably sleeved on the upper upright 103; wherein, the internal threaded cylinder 302 is threadedly connected to the external threaded cylinder 301; a plurality of elastic elements 303 are fixedly arranged in a ring array on the external threaded cylinder 301.

[0033] This utility model comprises an external threaded cylinder 301, an internal threaded cylinder 302, an elastic element 303, an extrusion block 304, and an extrusion groove 305. By rotating the internal threaded cylinder 302, the inner wall of the extrusion groove 305 extrudes the inclined surface of the extrusion block 304, causing the elastic element 303 to deform and tilt, allowing the extrusion block 304 to contact the surface of the upper retaining ring 204, thus facilitating the fixation of the upper retaining ring 204 in the adjustment groove 102.

[0034] Working principle of this utility model:

[0035] Before use, this device for correcting the verticality of drainage risers needs to be assembled. The assembly sequence is as follows: First, pull the upper upright 103 out from the lower upright 101. The specific extension length (height) depends on the installation height of the water supply and drainage riser in use. Ideally, the lower retaining ring 202 and the upper retaining ring 204 should be located at the upper and lower ends of the water supply and drainage riser to be assisted, respectively. This will ensure the verticality of the installed water supply and drainage riser as much as possible. Second, thread the lower retaining ring 202 to the lower threaded block 201 and the upper retaining ring 204 to the upper threaded block 203. During the assembly process, ensure that the lower retaining ring 202 and the upper retaining ring 204 are vertically aligned to ensure that they can fit tightly against the outer surface of the water supply and drainage riser during use, thus achieving the correction function.

[0036] The disassembly sequence of this utility model is as follows:

[0037] First, remove the lower retaining ring 202 and the upper retaining ring 204 by twisting the lower retaining ring 202 or the upper retaining ring 204 until they are completely removed from the lower upright 101 or the upper upright 103. Second, loosen the fastening component 3 at the connection between the lower upright 101 and the upper upright 103 so that it is in a semi-open state. In this state, retract the upper upright 103 into the lower adjusting groove 102.

[0038] After the above two steps, the disassembled parts of the device are stored in a packaging bag. The assembly and disassembly of the entire device can be completed by the above operation steps.

[0039] Before use, the device should be assembled according to the above assembly method. Before use, a preliminary device calibration should be performed. The calibration method is to use the three circular air level bulbs in the device to mutually calibrate and check each other. If the three circular air level bulbs can be centered at the same time, it means that the instrument used to measure the water supply and drainage riser in the device is in a valid state. Otherwise, the circular air level bulb in the device is in a malfunctioning state and needs to be calibrated.

[0040] The assembled and calibrated device is then tightly attached to the outer surface of the water supply and drainage riser to be installed. This operation requires two people working together: one to install the riser and the other to use the device to measure the verticality of the riser. The first person installs the riser and initially corrects its verticality. After the initial verticality correction, a temporary support is provided for the riser. Once the support is in place, the lower retaining ring 202 arc surface A and the upper retaining ring 204 arc surface B are evenly and tightly attached to the surface of the riser. It is important to remember... The lower retaining ring 202 and the upper retaining ring 204 are simultaneously pressed tightly against the water supply and drainage riser. Then, according to the circular spirit level with numerical scale set on the lower upright 101 of the device, the deviation value of the water supply and drainage riser is taken. If the actual deviation value is within the allowable error value, no secondary correction of the water supply and drainage riser is required. If the actual deviation value is outside the allowable error value, the water supply and drainage riser needs to be corrected. The method and steps of the secondary correction are the same as the above operation steps, until the verticality of the water supply and drainage riser meets the corresponding specification value requirements.
