Technical Field

[0001] The utility model relates to a steel bar diameter detection device for engineering detection, belonging to the field of steel bar detection. Background Art

[0002] During the construction process, the quality of the steel bars needs to be supervised, which requires the use of measuring devices to measure the diameter of the steel bars. The common measurement procedure is to first use a vernier caliper to measure the steel bars at multiple points, and then take the average of the measurement results, which can ensure that the measurement results of the steel bars are more accurate, thereby improving the accuracy of quality assessment.

[0003] In the prior art, since it is necessary to use a vernier caliper to perform multiple measurements when measuring multiple points of steel bars, and it is also necessary to use a steel ruler to measure the distance between two measuring points, the measuring steps are relatively cumbersome. Therefore, in order to improve the efficiency of measurement, some detection devices will be provided with a track marked with scales and a number of vernier calipers will be slidably connected to the surface of the track. The vernier calipers are moved to slide on the track to control the spacing between the vernier calipers, and then the vernier calipers are fixed to the surface of the slide rail by tightening the bolts. Finally, the vernier caliper cursor can be adjusted to quickly read the diameter of the steel bars at each point and the distance between two adjacent measuring points. Although the above device simplifies the measuring steps, due to the long slide rail, the device is large in size and inconvenient to carry, and the length of the slide rail is limited, resulting in a limited range of measurement points. Utility Model Content

[0007] Furthermore, the limiting assembly includes a plurality of guide rods slidably connected to the support frame, one end of the guide rod close to the steel bar is fixedly connected to a limiting plate, the other end of the guide rod is fixedly connected to a pull plate, a limiting spring is sleeved on the surface of the guide rod, and the limiting spring and the support frame, as well as the limiting spring and the limiting plate are fixedly connected.

[0008] Furthermore, the inner wall of the bottom end of the support frame is higher than the inner wall of the bottom end of the vernier caliper, and the bottom end of the first base, the bottom end of the second base and the bottom end of the vernier caliper are located on the same horizontal line.

[0009] Furthermore, a non-slip cover is provided on the surface of the locking member, and a handle is rotatably connected to one end of the first base away from the tape measure.

[0010] Furthermore, an inner wall of the support frame and a side of the limiting plate close to the steel bar are both movably connected with an anti-skid pad, and the anti-skid pad and the support frame, and the anti-skid pad and the limiting plate are fixed by bolts.

[0011] The beneficial effects of the utility model are as follows: the pull plate, the guide rod and the limit spring in the limit assembly can leave enough space between the limit plate and the inner wall of the support frame to accommodate the steel bar, thereby avoiding displacement of the steel bar when measuring the steel bar, which is beneficial to improving the measurement efficiency and the accuracy of the measurement result;

[0012] By adjusting the winding rod, winding drum and spring spring in the assembly, one end of the measuring tape can be driven in and out of the first base, so that the length of the measuring tape can be adjusted according to actual conditions and then rotated. The length of the measuring tape can be limited by cooperating with the locking frame and the locking piece. The moving seat can be pulled to drive the vernier caliper to slide along the surface of the measuring tape. The moving seat can be fixed on the corresponding position of the measuring tape by cooperating with the locking frame and the locking piece, so that the spacing between each vernier caliper can be quickly adjusted, which is convenient for simultaneous measurement of multiple points of the steel bar. The diameter of the steel bar at each point can be read by adjusting the vernier on the surface of the vernier caliper. The average value can be calculated according to the above measurement results to complete the measurement of the steel bar diameter.

DETAILED DESCRIPTION

[0018] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further described below in conjunction with specific implementation methods.

[0019] See also Figure 1 , Figure 2 and Figure 3The utility model provides a technical solution: a steel bar diameter detection device for engineering inspection, comprising a first base 1, an adjusting component 2 is fixedly connected to the inner wall of the first base 1, a second base 3 is arranged on one side of the adjusting component 2, a support frame 4 is fixedly connected to the top of the first base 1 and the second base 3, a limiting component 5 is arranged on the inner wall of the support frame 4, a steel bar is movably connected in the limiting component 5, and a vernier caliper 6 is arranged on the top of the adjusting component 2.

[0020] The pull plate 53, the guide rod 51 and the limit spring 54 in the limit assembly 5 can leave enough space between the limit plate 52 and the inner wall of the support frame 4 to accommodate the steel bars, thereby avoiding displacement of the steel bars when measuring the steel bars, which is beneficial to improving the measurement efficiency and the accuracy of the measurement results;

[0021] By adjusting the winding rod 21, winding drum 22 and spring spring 23 in the assembly 2, one end of the measuring tape 24 can be driven to move in and out of the first base 1, so that the length of the measuring tape 24 can be adjusted according to the actual situation and then rotated. By cooperating with the locking frame 26 and the locking member 27, the length of the measuring tape 24 can be limited. By pulling the movable seat 25, the vernier caliper 6 can be driven to slide along the surface of the measuring tape 24. By cooperating with the locking frame 26 and the locking member 27, the movable seat 25 can be fixed at the corresponding position of the measuring tape 24, so that the spacing between each vernier caliper 6 can be quickly adjusted, which is convenient for adjusting the steel bars. Simultaneous measurement of multiple points can be performed, and the diameter of the steel bar at each point can be read by adjusting the vernier on the surface of the vernier caliper 6. The average value can be calculated based on the above measurement results to complete the measurement of the steel bar diameter. After the measurement is completed, the device can be stored according to the above steps, which not only greatly reduces the space occupied by the device and is convenient for carrying the device, but also because the tape measure 24 is long, the selection range of the measurement point can be expanded, and the accuracy of the measurement result can be further improved. Since the tape measure 24 is fixed to the second base 3 by bolts, it is convenient to replace and increase or decrease the vernier caliper 6.

[0022] See also Figure 1 , Figure 2 and Figure 3The adjusting assembly 2 includes a winding rod 21 fixedly connected to the inner wall of the first base 1, a winding drum 22 is rotatably connected to the surface of the winding rod 21, a spring spring 23 is fixedly connected to the inner wall of the winding rod 21, the other end of the spring spring 23 extends out of the winding drum 22 and is fixedly connected to a measuring tape 24, a plurality of moving seats 25 are slidably connected to the surface of the measuring tape 24, a locking frame 26 is fixedly connected to one side of the first base 1 and one side of the moving seat 25, a locking member 27 is internally threadedly connected to the locking frame 26, and an end of the measuring tape 24 away from the spring spring 23 is fixed to the second base 3 by bolts. According to the actual situation, the second base 3 is pulled in the direction away from the first base 1. The movement of the second base 3 will drive the winding drum 22 mounted on the surface of the winding rod 21 to rotate and cause the spring spring 23 to deform, thereby driving one end of the measuring tape 24 to move in the direction away from the first base 1. After the measuring tape 24 is unfolded to a suitable length, the locking piece 27 is rotated to make it move along the locking frame 26 toward the measuring tape 24 until the locking piece 27 and the locking frame 26 are tightly against both sides of the measuring tape 24, thereby limiting the length of the measuring tape 24. Then, the moving seat 25 is pulled to make it drive the vernier caliper 6 to slide along the surface of the measuring tape 24. After the moving seat 25 moves to a suitable position, the locking piece 27 is rotated to make it tightly against both sides of the measuring tape 24, so that the moving seat 25 can be fixed at the corresponding position of the measuring tape 24, thereby enabling the spacing between each vernier caliper 6 to be quickly adjusted, which is convenient for simultaneous measurement of multiple points of the steel bars. Finally, the vernier calipers 6 are adjusted. The vernier on the surface of the caliper 6 can read the diameter of the steel bar at each point, and the average value can be calculated based on the above measurement results to complete the measurement of the steel bar diameter. After the measurement is completed, the locking piece 27 is rotated in the direction away from the measuring tape 24. At this time, the clockwork spring 23 will be restored and drive the measuring tape 24 to move toward the inside of the first base 1 and be wound onto the surface of the winding drum 22, thereby driving the moving seat 25 and the second base 3 to move toward the first base 1. After the measuring tape 24 is wound, the locking piece 27 is rotated so that it is tightly against the two sides of the end of the measuring tape 24 exposed from the first base 1, and the storage of the device can be completed. Not only the space occupied by the device is greatly reduced, and the device is convenient to carry, but also because the measuring tape 24 is long, the selection range of the measuring point can be expanded, and the accuracy of the measurement result is further improved. Since the measuring tape 24 and the second base 3 are fixed by bolts, it is convenient to replace and increase or decrease the vernier caliper 6.

[0023] The limiting assembly 5 includes a plurality of guide rods 51 slidably connected to the support frame 4. One end of the guide rod 51 close to the steel bar is fixedly connected to the limiting plate 52. The other end of the guide rod 51 is fixedly connected to the pull plate 53. The surface of the guide rod 51 is sleeved with a limiting spring 54. The limiting spring 54 and the support frame 4, and the limiting spring 54 and the limiting plate 52 are all fixedly connected. First, the pull plate 53 is pulled away from the support frame 4 so that the guide rod 51 slides along the support frame 4 and drives the limiting plate 52 to squeeze the limiting spring 54 to shrink it to leave enough space to accommodate the steel bar. Then, the steel bar is placed on the top of the first base 1 and the second base 3. After the steel bar is placed, the pull plate 53 is released. The limiting spring 54 will reset and push the limiting plate 52 to move toward the steel bar until both sides of the steel bar are close to the limiting plate 52 and the inner wall of the support frame 4. Through the above steps, the steel bar can be fixed in the device, thereby avoiding displacement of the steel bar when measuring the steel bar, which is conducive to improving the measurement efficiency and the accuracy of the measurement results.

[0024] The inner wall of the bottom end of the support frame 4 is higher than the inner wall of the bottom end of the vernier caliper 6, and the bottom ends of the first base 1, the second base 3 and the vernier caliper 6 are located on the same horizontal line. The inner wall of the bottom end of the support frame 4 is higher than the inner wall of the bottom end of the vernier caliper 6 to ensure that the steel bar can always remain horizontal on the device, and the bottom ends of the first base 1, the second base 3 and the vernier caliper 6 are located on the same horizontal line to prevent the tape measure 24 from bending due to the vernier caliper 6 being suspended in the air, which not only ensures the accuracy of the measurement result, but also helps to extend the service life of the tape measure 24.

[0025] The surface of the locking member 27 is covered with an anti-skid cover 8, and the end of the first base 1 away from the tape measure 24 is rotatably connected with a handle 9. The anti-skid cover 8 can increase the friction between the locking member 27 and the tape measure 24, thereby further improving the effect of the locking member 27 fixing the tape measure 24. The device can be lifted by providing the handle 9, so that it is easy to carry the device. Since the anti-skid cover 8 is covered on the surface of the locking member 27, the anti-skid cover 8 can be replaced, thereby preventing the anti-skid cover 8 from being worn due to long-term use, further ensuring the fixing effect of the locking member 27. Since the handle 9 and the first base 1 are rotatably connected, the space occupied by the device can be reduced.

[0026] The inner wall of the support frame 4 and the side of the limiting plate 52 close to the steel bar are both movably connected with the anti-skid pad 7, and the anti-skid pad 7 is fixed to the support frame 4 and the limiting plate 52 by bolts. The anti-skid pad 7 can increase the friction between the support frame 4 and the steel bar, and between the limiting plate 52 and the steel bar, thereby further improving the effect of the support frame 4 and the limiting plate 52 on the steel bar. Since the anti-skid pad 7 is fixed to the support frame 4 and the limiting plate 52 by bolts, the anti-skid pad 7 can be replaced, thereby preventing the anti-skid pad 7 from being worn out due to long-term use, and further ensuring the effect of the support frame 4 and the limiting plate 52 on the steel bar.

[0027] Specific implementation method: first, pull the pull plate 53 in the direction away from the support frame 4 so that the guide rod 51 slides along the support frame 4 and drives the limit plate 52 to squeeze the limit spring 54 to shrink it to leave enough space to accommodate the steel bar, and then place the steel bar to the top of the first base 1 and the second base 3. After the steel bar is placed, release the pull plate 53, the limit spring 54 will reset and push the limit plate 52 to move towards the steel bar until both sides of the steel bar are close to the limit plate 52 and the inner wall of the support frame 4. Through the above steps, the steel bar can be fixed in the device, thereby avoiding the displacement of the steel bar when measuring the steel bar, which is beneficial to improving the measurement efficiency and the accuracy of the measurement results;

[0028] According to the actual situation, the second base 3 is pulled in the direction away from the first base 1. The movement of the second base 3 will drive the winding drum 22 mounted on the surface of the winding rod 21 to rotate and cause the spring spring 23 to deform, thereby driving one end of the measuring tape 24 to move in the direction away from the first base 1. After the measuring tape 24 is unfolded to a suitable length, the locking piece 27 is rotated to make it move along the locking frame 26 toward the measuring tape 24 until the locking piece 27 and the locking frame 26 are tightly against both sides of the measuring tape 24, thereby limiting the length of the measuring tape 24. Then, the moving seat 25 is pulled to make it drive the vernier caliper 6 to slide along the surface of the measuring tape 24. After the moving seat 25 moves to a suitable position, the locking piece 27 is rotated to make it tightly against both sides of the measuring tape 24, so that the moving seat 25 can be fixed at the corresponding position of the measuring tape 24, thereby enabling the spacing between each vernier caliper 6 to be quickly adjusted, which is convenient for simultaneous measurement of multiple points of the steel bars. Finally, the vernier calipers 6 are adjusted. The vernier on the surface of the caliper 6 can read the diameter of the steel bar at each point, and the average value can be calculated based on the above measurement results to complete the measurement of the steel bar diameter. After the measurement is completed, the locking piece 27 is rotated in the direction away from the measuring tape 24. At this time, the clockwork spring 23 will be restored and drive the measuring tape 24 to move toward the inside of the first base 1 and be wound onto the surface of the winding drum 22, thereby driving the moving seat 25 and the second base 3 to move toward the first base 1. After the measuring tape 24 is wound, the locking piece 27 is rotated so that it is tightly against the two sides of the end of the measuring tape 24 exposed from the first base 1, and the storage of the device can be completed. Not only the space occupied by the device is greatly reduced, and the device is convenient to carry, but also because the measuring tape 24 is long, the selection range of the measuring point can be expanded, and the accuracy of the measurement result is further improved. Since the measuring tape 24 and the second base 3 are fixed by bolts, it is convenient to replace and increase or decrease the vernier caliper 6.

[0029] In addition, it should be understood that although the present specification is described according to implementation modes, not every implementation mode contains only one independent technical solution. This description of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment may also be appropriately combined to form other implementation modes that can be understood by those skilled in the art.
