[0002] The wall thickness of steel pipes needs to be measured during the production process. The existing steel pipe size measurement is mainly done manually by inserting a simple caliper into the end of the steel pipe, contacting the two claws of the caliper with the inner and outer walls of the steel pipe respectively, then pulling the caliper backwards, aligning the caliper with the ruler for data comparison, and determining the measurement data based on the comparison results.
[0003] However, the above measurement method has the following shortcomings:
[0004] 1. During the measurement process, the measuring personnel come into close contact with the high-temperature steel pipe of about 800℃, which may easily cause burns to their arms;

DETAILED DESCRIPTION
[0029] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0030] Example: Reference Figure 1-3 The high temperature steel pipe size measuring device shown in the figure comprises a caliper 4 and a ruler 5. The holding end of the caliper 4 is integrally provided with an extension section 401. The tail end of the extension section 401 is rotatably mounted with the ruler 5. Figure 1The caliper 4 in the prior art, the caliper 4 in the present scheme can be held by the staff at a long distance through the provided extension section 401. In addition, the extension section 401 is preferably made of heat-insulating material to reduce the probability of scalding time, and the ruler 5 is rotatably installed at the tail end of the extension section 401. The ruler 5 can maintain a vertical state under the action of its own gravity, and the measurement can be completed while the caliper 4 is clamped. It should be further explained that the above-mentioned measurement process is based on the principle of lever, so that the ratio of the measuring end and the reading end is enlarged to achieve improved measurement accuracy, and the specific thickness of the steel pipe is converted according to the existing conversion formula.
[0031] The clamping end of the caliper 4 is integrally provided with an extension block 402 , and the extension block 402 can maintain linear contact with the surface of the steel pipe when clamping the steel pipe to measure the thickness, thereby realizing automatic calibration and making the measurement more accurate.
[0032] In addition, it also includes a fixed frame 1, a lifting seat 2 and a lifting adjustment mechanism. The lifting seat 2 is located on the upper side of the fixed frame 1 and is connected to the fixed frame 1 through the lifting adjustment mechanism. The caliper 4 is rotatably installed on the upper side of the lifting seat 2. The lifting adjustment mechanism includes a transmission assembly 6 and a support frame 8. An extension seat 7 is integrally provided on one side of the fixed frame 1 close to the holding end of the caliper 4. The support frame 8 is installed on the upper end of the extension seat 7. The transmission assembly 6 is installed between the support frame 8, the fixed frame 1 and the lifting seat 2.
[0033] More specifically, the transmission assembly 6 includes an internal threaded sleeve 61, a threaded rod 62, a transmission sprocket 63, a transmission chain 64 and an operating shaft 65. The internal threaded sleeve 61 is vertically fixed to the bottom end of the lifting seat 2 and slides through the fixed frame 1. The threaded rod 62 is threadedly sleeved on the inner side of the internal threaded sleeve 61, and the threaded rod 62 is rotatably installed on the inner bottom end of the fixed frame 1. The operating shaft 65 is vertically rotatably installed on the support frame 8. Two transmission sprockets 63 are provided, and the two transmission sprockets 63 are coaxially fixed to the bottom ends of the threaded rod 62 and the operating shaft 65 respectively. The transmission chain 64 is transmission-connected between the two transmission sprockets 63. A guide rod 9 that slides through the fixed frame 1 is vertically installed at the bottom end of the lifting seat 2.
[0034] Based on the coordinated arrangement of the above structure, the fixed frame 1 can support the caliper 4 and reduce the burden of manual holding. In addition, the fixed frame 1 is preferably equipped with moving wheels at the bottom to facilitate flexible movement. When the height of the caliper 4 needs to be adjusted, the staff can manually rotate the operating shaft 65. The operating shaft 65 rotates with the threaded rod 62 through the transmission sprocket 63 and the transmission chain 64, thereby driving the internal threaded sleeve 61 to lift the lifting seat 2, thereby lifting the caliper 4.
[0035] Among them, an adaptive connector 3 is installed at the upper end of the lifting seat 2, and a mounting seat 11 is installed at the top of the adaptive connector 3. The caliper 4 is rotatably installed on the mounting seat 11. Specifically, the adaptive connector 3 includes a limit column 31, a spring 32 and a limit sleeve 33. The limit column 31 is fixed to the upper end of the lifting seat 2, and the limit sleeve 33 is slidably sleeved on the outer side of the limit column 31. The limit sleeve 33 is fixed between the limit column 31 and the spring 32, and the mounting seat 11 is fixed to the upper end of the spring 32.
[0036] After using the lifting and adjusting mechanism to roughly adjust the height of the caliper 4, during the clamping process, the limit column 31, spring 32 and limit sleeve 33 can be used to cooperate to automatically level the caliper 4, that is, the rotating connection between the caliper 4 and the mounting seat 11 is flush with the middle position of the steel pipe measuring part, ensuring that the extended clamp block 402 maintains linear contact with the surface of the steel pipe when clamping the steel pipe to measure the thickness, and the measurement is more accurate.
[0037] Among them, two laser emitters 10 are installed at the clamping end of the mounting seat 11 close to the caliper 4. The two laser emitters 10 are symmetrically arranged up and down about the rotating connection between the caliper 4 and the mounting seat 11. When the staff roughly adjusts the height of the caliper 4, they can make a rough adjustment by observing the position of the laser line emitted by the laser emitter 10, that is, the laser lines emitted by the two laser emitters 10 are respectively located on the outside and inside of the steel pipe.
[0038] Working principle of the utility model: the staff pushes the device to the measuring position and manually rotates the operating shaft 65. The operating shaft 65 rotates with the threaded rod 62 through the transmission sprocket 63 and the transmission chain 64, thereby driving the internal threaded sleeve 61 to lift the lifting seat 2, thereby lifting the caliper 4. Specifically, the position of the laser line emitted by the laser emitter 10 can be roughly adjusted, that is, the laser lines emitted by the two laser emitters 10 are respectively located on the outside and inside of the steel pipe. At this time, the extension section 401 can be held so that the extension block 402 maintains linear contact with the surface of the steel pipe when clamping the steel pipe to measure the thickness. During the clamping process, the limit column 31, the spring 32 and the limit sleeve 33 can be used to cooperate with each other to play an automatic leveling role on the caliper 4, so that the measurement is more accurate. The ruler 5 can maintain a vertical state under the action of its own gravity, and the measurement is completed while the caliper 4 is clamped.
[0039] Finally, it should be noted that the above is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the aforementioned embodiments, it is still possible for those skilled in the art to modify the technical solutions described in the aforementioned embodiments, or to make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present utility model shall be included in the protection scope of the present utility model.
