Description

TECHNICAL FIELD

[0001] The utility model belongs to the technical field of steel bar diameter detector, especially to a steel bar diameter detection device. BACKGROUND

[0002] Steel bar is the main force component in building structure, and its diameter directly affects the bearing capacity and stability of the structure. Therefore, in the process of building construction, the diameter of steel bar needs to be detected. Through the detection of steel bar diameter, it can ensure that the steel bar meets the design requirements and relevant standards, thereby ensuring the safety of the building. At the same time, it can find possible problems, such as excessive size deviation of steel bar, so as to take corresponding measures to prevent safety hazards in the use process of the structure.

[0003] When measuring the diameter of round steel bar and ribbed steel bar, the current existing method is to use a vernier caliper to repeatedly measure the diameter of the steel bar at the same position in different directions for at least three times, and the arithmetic mean of the three measurement results is taken as the steel bar diameter detection value at the measurement point. Therefore, when measuring the diameter of the steel bar in different directions, the steel bar needs to be rotated. When rotating, the steel bar needs to be manually turned over. When manually turning over the steel bar, the turning range cannot be accurately controlled, so the steel bar cannot be uniformly rotated, and the same direction may be repeatedly measured, thereby it is difficult to ensure the accuracy of the diameter measurement.

DETAILED DESCRIPTION

[0019] The present invention will be further described below with reference to the accompanying drawings and specific embodiments, but this is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.

[0020] Example

[0021] The steel bar diameter detection device described in this embodiment, such as Figure 1 As shown, it includes a horizontally set base plate 1, and four suction cups 16 arranged in a rectangular pattern are fixed to the bottom of the base plate 1; the design of the suction cups 16 ensures the stability of the base plate 1 during use.

[0022] like Figure 1 and Figure 2 As shown, a support plate 14 is provided on the top of the base plate 1, and a limit tube 15 is vertically provided on the top of the support plate 14. The lower end of the limit tube 15 is rotatably connected to the support plate 14. Specifically, when implementing the rotatable connection, a first blind hole can be opened on the top of the support plate 14, and a first bearing can be installed in the first blind hole. The outer ring of the first bearing is fixed in the first blind hole, and the lower end of the limit tube 15 is rotatably connected to the inner ring of the first bearing. Therefore, the limit tube 15 can rotate freely on the support plate 14, thereby realizing the rotatable connection.

[0023] like Figure 2 As shown, a pointer 17 is fixed on the outer wall of the limiting tube 15. Since the limiting tube 15 can rotate freely and the pointer 17 is fixed on it, the limiting tube 15 can drive the pointer 17 to rotate along its circumference.

[0024] like Figure 1 and Figure 2As shown, the limiting tube 15 is provided with a first clamping plate 12 and a second clamping plate 13, both of which are located in the limiting tube 15. Threaded holes are formed in the limiting tube 15 and communicate with the outside. A screw rod 11 is threaded into the threaded holes. One end of the screw rod 11 is rotatably connected to the first clamping plate 12, and the second clamping plate 13 is fixed in the limiting tube 15. The first clamping plate 12 and the second clamping plate 13 are arranged side by side, with the second clamping plate 13 located to the left of the first clamping plate 12. The threaded holes are formed on the right side of the limiting tube 15. When the one end of the screw rod 11 is rotatably connected to the first clamping plate 12, a second blind hole can be formed in the right side wall of the first clamping plate 12. A second bearing is installed in the second blind hole. The outer ring of the second bearing is fixed in the second blind hole, and the one end of the screw rod 11 is fixed to the inner ring of the second bearing. Therefore, when the screw rod 11 rotates, the first clamping plate 12 will not rotate, thereby achieving a rotary connection. When the screw rod 11 moves left and right in the threaded hole, it can drive the first clamping plate 12 to move left and right. In use, the steel bar 2 to be detected is first cut into small sections using a cutting machine. The cut steel bar 2 is then placed vertically between the first clamping plate 12 and the second clamping plate 13. The first clamping plate 12 is then moved by turning the screw rod 11, which can clamp the steel bar 2 between the first clamping plate 12 and the second clamping plate 13, achieving the purpose of fixing the steel bar 2. Because the steel bar 2 is fixed in the limiting tube 15, and the limiting tube 15 can rotate on the supporting plate 14, the limiting tube 15 can rotate when the steel bar 2 rotates.

[0025] In implementation, the first clamping plate 12 and the second clamping plate 13 in the clamping assembly are preferably arc-shaped, which can increase the contact area between the first clamping plate 12, the second clamping plate 13 and the steel bar 2, thereby clamping the steel bar 2 more stably between the first clamping plate 12 and the second clamping plate 13.

[0026] As Figure 1 and Figure 3As shown, the upper portion of the bottom plate 1 is provided with a measuring scale 6, the top of the bottom plate 1 is fixed with two support rods 3 arranged left and right, the measuring scale 6 is fixed between the two support rods 3 through the limiting block 4; the measuring scale 6 is sleeved with a sliding block 8 which is in sliding cooperation with the measuring scale 6; the front side of the measuring scale 6 is provided with a first clamping block 5 and a second clamping block 7, the first clamping block 5 is fixed on the measuring scale 6, and the second clamping block 7 is fixed on the sliding block 8; the whole scheme constitutes a measuring assembly for measuring the diameter of the reinforcing steel bar 2; the measuring scale 6 is horizontally arranged; the bottom of the support rod 3 is fixed on the top of the bottom plate 1; when the measuring scale 6 is connected with the support rod 3 through the limiting block 4, the top of the support rod 3 is fixed with the limiting block 4, the right side wall of the limiting block 4 on the top of the left side support rod 3 is provided with a groove for clamping the left end of the measuring scale 6, and the left side wall of the limiting block 4 on the top of the right side support rod 3 is provided with a groove for clamping the right end of the measuring scale 6; the grooves are communicated with the front side wall of the limiting block 4, so that the measuring scale 6 is convenient to clamp into the groove from the front side of the limiting block 4; after the left end of the measuring scale 6 is clamped into the groove on the left side limiting block 4 and the right end of the measuring scale 6 is clamped into the groove on the right side limiting block 4, the measuring scale 6 can be limited between the two limiting blocks 4; the top of the limiting block 4 is provided with a threaded hole which is communicated with the inside of the groove, and a fastening screw which is in threaded cooperation with the threaded hole is screwed in the threaded hole, so that the fastening screw can abut against the measuring scale 6 during the screwing process, and the measuring scale 6 can be clamped more stably in the groove of the limiting block 4; the first clamping block 5 is located on the left side of the second clamping block 7, the rear side wall of the first clamping block 5 is fixed on the front side wall of the measuring scale 6, and the rear side wall of the second clamping block 7 is fixed on the front side wall of the sliding block 8; the top of the measuring scale 6 is provided with a scale line, and the starting position of the scale line on the measuring scale 6 corresponds to the right side wall of the first clamping block 5; because the sliding block 8 can slide on the measuring scale 6, the sliding of the sliding block 8 can drive the sliding of the second clamping block 7, preferably, an inwardly communicated threaded hole is also provided on the sliding block 8, and a fastening screw which is in threaded cooperation with the threaded hole is also screwed in the threaded hole, so that when the sliding block 8 slides to a specified position, the position of the sliding block 8 can be fixed by screwing the fastening screw, thereby fixing the position of the second clamping block 7; in use, the lower half of the reinforcing steel bar 2 is fixed in the limiting tube 15, and the upper half of the reinforcing steel bar 2 is not limited, at this time, the upper half of the reinforcing steel bar 2 is placed between the first clamping block 5 and the second clamping block 7, then the reinforcing steel bar 2 is clamped between the first clamping block 5 and the second clamping block 7 by sliding the sliding block 8 to drive the second clamping block 7 to slide, and then the diameter of the reinforcing steel bar 2 can be detected by observing the scale value on the measuring scale 6; in order to detect the diameters of the reinforcing steel bar 2 in different directions at the same position, because the lower half of the reinforcing steel bar 2 is fixed on the limiting tube 15, and the limiting tube 15 can rotate on the support plate 14, the reinforcing steel bar 2 can be rotated, and the diameter of the reinforcing steel bar 2 after rotation can be measured again, so that the diameters in different directions at the same position can be measured.At the same time, because the pointer 17 is fixed on the outer side wall of the limiting tube 15, when the limiting tube 15 is rotated, the rotation range of the reinforcing steel bar 2 can be determined according to the position of the observed pointer 17, so that the reinforcing steel bar 2 can be rotated to different orientations as evenly as possible, and the accuracy of diameter measurement is improved as much as possible;

[0027] In implementation, the measuring assembly can also be directly replaced by a vernier caliper;

[0028] As shown in Figure 1 , the top of the bottom plate 1 is provided with a sliding groove for supporting the left and right sliding of the supporting plate 14, and the supporting plate 14 is in left and right sliding cooperation with the sliding groove; therefore, the supporting plate 14 can slide left and right, and the supporting plate 14 can drive the limiting tube 15 to slide left and right during the left and right sliding process, and the limiting tube 15 can drive the reinforcing steel bar 2 to move, so that the reinforcing steel bar 2 can be moved to the position of the right side wall of the first clamping block 5, thereby facilitating the movement of the reinforcing steel bar 2 to the position of the measuring start point of the measuring ruler 6;

[0029] As shown in Figure 1 , the right side wall of the supporting plate 14 is fixed with a pull rod 10 for facilitating the left and right movement of the supporting plate 14 in the sliding groove; the pull rod 10 is horizontally arranged, and the left end of the pull rod 10 is fixed on the supporting plate 14; in use, the left and right movement of the supporting plate 14 is facilitated by pulling the pull rod 10 to move;

[0030] As shown in Figure 1 , the pull rod 10 is fixed with a handle 9, and the handle 9 is fixed at the right end of the pull rod 10; through the design of the pull rod 10, the pull rod 10 can be operated more conveniently;

[0031] As shown in Figure 1 and Figure 2 , the top of the supporting plate 14 is provided with a pointer mark 18 for identifying the rotation position of the pointer 17; according to Figure 2 , it can be seen that the pointer mark 18 is designed to have a circular ring on the supporting plate 14 outside the limiting tube 15, and a plurality of indication strips are designed at equal intervals along the circumferential direction of the inner side of the circular ring; therefore, during the rotation of the pointer 17, the pointer 17 can be rotated to different indication strip positions, and because the indication strips are arranged at equal intervals, the rotation of the pointer 17 along the indication strip positions can make the limiting tube 15 rotate at equal intervals during the rotation, thereby driving the reinforcing steel bar 2 to rotate at equal intervals to different orientations, and when the diameter of the reinforcing steel bar 2 at the same position in different orientations is measured, the reinforcing steel bar 2 can be rotated as evenly as possible, thereby improving the stability during detection;

[0032] In the specific use process: first, the steel bar 2 is cut off the sample placed in the limiting tube 15, and is located between the second clamp plate 13 and the first clamp plate 12, and then the screw rod 11 is twisted to move the first clamp plate 12 to clamp the lower half of the steel bar 2 in the limiting tube 15; at the same time, the upper half of the steel bar 2 is located between the first clamp block 5 and the second clamp block 7, and then the support plate 14 is moved to drive the limiting tube 15 to move, the limiting tube 15 drives the steel bar 2 to move, and then the steel bar 2 moves to the right side of the first clamp block 5 and is attached thereto, and then the slider 8 is moved to drive the second clamp block 7 to move, so that the upper half of the steel bar 2 is clamped between the first clamp block 5 and the second clamp block 7, and the purpose of diameter measurement is achieved; then, when measuring different directions at the same position, the limiting tube 15 is rotated, the limiting tube 15 drives the pointer 17 to rotate, the pointer 17 is rotated to different positions on the pointer mark 18, the steel bar 2 at the rotated position is repeatedly measured, and the purpose of measuring different directions at the same position is achieved, and then the measured results are calculated to obtain the average value, which is the diameter detection value of the steel bar 2; in this use process, the limiting tube 15 can uniformly rotate the steel bar 2, which can improve the accuracy of the diameter measurement of the steel bar 2 during multiple measurements; and the problem that the steel bar 2 needs to be manually rotated during diameter measurement in the prior art, which leads to uneven rotation and may cause inaccurate measurement, is avoided.
