Technical Field

[0001] The utility model relates to the technical field of circular cross-section measurement, in particular to circular cross-section measurement equipment for cement poles. Background Art

[0002] Cement poles are poles made of concrete and steel bars or steel wires. During the production process of cement poles, it is necessary to measure the cross-sectional area of ​​cement poles. These measurements are crucial for evaluating the structural strength, reinforcement design and subsequent mechanical properties testing of the poles.

[0003] When measuring the circular cross-sectional area of ​​existing cement poles, the diameter of the cement pole is usually measured directly by a caliper. However, the process of measuring the diameter by a caliper is relatively rough. When in use, the caliper is placed in an inclined position, resulting in errors in the measured diameter data, which in turn affects the accurate measurement of the circular cross-section of the cement pole. For this reason, technical personnel in this field have proposed a circular cross-section measuring device for cement poles to solve the problems raised in the above background.

[0009] The linkage component is arranged in the annular frame and located between two adjacent transmission components, and is used to drive multiple transmission components to transmit synchronously.

[0010] As a further solution of the utility model: a rotating shaft is rotatably provided at one end of the sliding frame close to the center of the annular frame, and a pressure roller is installed on the rotating shaft.

[0013] As a further solution of the utility model: the linkage component includes an inner cavity opened in the annular frame and located on both sides of the transmission cavity, a linkage shaft is rotatably arranged in the inner cavity, first bevel gears are installed at both ends of the linkage shaft, and a second bevel gear meshing with the first bevel gear is installed at one end of the transmission shaft that penetrates the inner cavity.

[0021] The technical solution of the present application is further described in detail below in conjunction with specific implementation methods.

[0022] See also Figure 1-Figure 5 , a circular cross-section measuring device for cement poles, comprising an annular frame 1; a plurality of slide grooves 2 are arranged at annular intervals on the annular frame 1, a slide frame 3 is slidably arranged in the slide groove 2, a first connecting block 6 is installed on the top of the end of the slide frame 3 away from the center of the annular frame 1, a second connecting block 7 is installed on the top of the slide groove 2 on the annular frame 1, scales 11 are arranged on both sides of the slide frame 3, and pointers 10 are arranged on both sides of the slide groove 2 on the annular frame 1. It should be noted that the setting data of the scales 11 on both sides of the slide frame 3 can be different, wherein the data on the scale 11 on one side can be set to the diameter, and the data on the scale 11 on the other side can be set to the radius, and also includes:

[0023] An elastic component, which is arranged between the first connecting block 6 and the second connecting block 7 and is used to provide elastic tension;

[0024] A transmission component, which is arranged in the annular frame 1, and there are multiple transmission components, which are distributed in an annular manner and are used to drive the sliding frame 3 to move;

[0025] The linkage component is arranged in the annular frame 1 and is located between two adjacent transmission components, and is used to drive multiple transmission components to transmit synchronously.

[0026] When in use, first pull one of the first connecting blocks 6 to make the sliding frame 3 move toward the end away from the center of the annular frame 1, and under the action of the transmission parts and the linkage parts, the remaining sliding frames 3 will also slide synchronously to the outside of the annular frame 1. At this time, the annular frame 1 can be put on the outer end of the cement pole, and the annular frame 1 is moved to the position to be measured of the cement pole, and the first connecting block 6 is released. Under the action of the elastic component, multiple sliding frames 3 will synchronously move toward the cement pole in the middle of the annular frame 1 until the ends of multiple sliding frames 3 are all against the outer wall of the cement pole. Due to the joint pulling action of the evenly distributed elastic components, the annular frame 1 and the cement pole tend to be coaxial, thereby improving the measurement accuracy. At this time, the diameter of the cement pole can be directly obtained by reading the data on the scale 11 pointed to by the pointer 10, and then accurate diameter data can be obtained, which is convenient for calculating the circular cross-sectional area of ​​the cement pole, and the use process of the entire equipment is also relatively simple.

[0027] In one case of this embodiment, a rotating shaft 4 is rotatably provided at one end of the sliding frame 3 close to the center of the annular frame 1 , and a pressure roller is installed on the rotating shaft 4 .

[0028] Under the action of the elastic component, multiple sliding frames 3 will synchronously move toward the cement pole in the middle of the annular frame 1 until the pressure rollers at the ends of the multiple sliding frames 3 are against the outer wall of the cement pole, so that the annular frame 1 is coaxial with the cement pole. At this time, the diameter of the cement pole can be directly obtained by reading the data on the scale 11 pointed by the pointer 10, and then the circular cross-sectional area of ​​the cement pole can be calculated.

[0029] In one case of this embodiment, the elastic component includes two telescopic rods 8 arranged between the first connecting block 6 and the second connecting block 7, the two telescopic rods 8 are symmetrically arranged, and a spring 9 is arranged between the first connecting block 6 and the second connecting block 7.

[0030] Under the action of the spring 9, the first connecting block 6 is subjected to elastic tension, so that under normal conditions the sliding frame 3 will slide into the interior of the annular frame 1. When measuring, in order to facilitate the annular frame 1 to be put on the outside of the cement pole, one of the first connecting blocks 6 is pulled first to move the sliding frame 3 to the end away from the center of the annular frame 1, and under the action of the transmission parts and the linkage parts, the remaining sliding frames 3 will also slide synchronously to the outside of the annular frame 1. At this time, the annular frame 1 can be put on the outer end of the cement pole and moved to the position to be measured on the cement pole.

[0031] In one case of this embodiment, the transmission component includes a plurality of transmission cavities 13 arranged in annular intervals in the annular frame 1, the transmission cavity 13 corresponds to the slide slot 2, a transmission shaft 14 is rotatably arranged in the transmission cavity 13, a transmission gear 15 is mounted on the transmission shaft 14, and a rack 12 meshing with the transmission gear 15 is mounted at the bottom of the sliding frame 3. The linkage component includes an inner cavity 16 arranged in the annular frame 1 and located on both sides of the transmission cavity 13, a linkage shaft 17 is rotatably arranged in the inner cavity 16, first bevel gears 18 are mounted at both ends of the linkage shaft 17, and a second bevel gear 19 meshing with the first bevel gear 18 is mounted at one end of the transmission shaft 14 that penetrates into the inner cavity 16.

[0032] When one of the connecting blocks is pulled, the sliding frame 3 will slide along the sliding groove 2, thereby driving the transmission gear 15 to rotate through the rack 12, so that the transmission shaft 14 rotates, and at the same time, the meshing first bevel gear 18 and the second bevel gear 19 and the linkage shaft 17 drive the remaining transmission shafts 14 to rotate, and the transmission gears 15 on the remaining transmission shafts 14 and the racks 12 on the remaining sliding frames 3 drive the sliding frames 3 to move synchronously, so that the synchronous movement of multiple sliding frames 3 can be achieved, and the elastic components can make the pressure rollers at the ends of multiple sliding frames 3 can simultaneously press against the outer wall of the cement pole, so that the annular frame 1 is coaxial with the cement pole, which is convenient for measuring the diameter data of the cement pole and avoids the influence of inaccurate measurement data on the final calculation result of the circular cross-sectional area.
