Description

Technical Field

[0001] This utility model relates to the field of engineering supervision technology, and in particular to a remote sensing measurement device for steel bar dimensions. Background Technology

[0004] Existing technologies mainly use rollers to convey and guide steel bars. Since the steel bars move in a straight line, and the probe can only detect the side of the steel bar facing the probe, the side facing downwards is difficult to measure. This limits the accuracy of the measurement and leaves room for optimization.

[0005] Therefore, we propose a remote sensing measurement device for steel bar dimensions. Utility Model Content

[0008] The base has a conveying groove on its top, and a roller for supporting the reinforcing bar is rotatably connected in the conveying groove. A crossbeam is fixedly installed on the top of the base, and an electric actuator is fixedly installed on the top of the crossbeam. A remote sensing probe for measurement is fixedly installed on the output shaft of the electric actuator.

[0009] A lateral limiting component is installed at the top of the base to limit the movement of the reinforcing bar laterally;

[0010] A top limiting component is disposed above the base to limit the movement of the reinforcing bar. The top limiting component includes a first pressure roller, a second pressure roller, an extrusion groove, and a drive motor. The first and second pressure rollers are elastically connected to the base through connectors. The second pressure roller has an extrusion groove. The output shaft of the drive motor is fixedly connected to the extrusion groove to drive the second pressure roller to rotate. Several first and second pressure rollers are alternately arranged on the top of the base. The extrusion groove can push the reinforcing bar to rotate.

[0013] In a preferred embodiment of this utility model, the vertical plate is a rectangular plate, the ear plate is a trapezoidal block, the ear plate is fixedly disposed on one side of the vertical plate, and the joint formed by the vertical plate and the ear plate is adapted to the first limiting groove.

[0014] In a preferred embodiment of this utility model, the first pressure roller and the second pressure roller have the same shape. The two ends of the first pressure roller are circular plates, and the middle part of the first pressure roller is a cylinder with a diameter smaller than that of the circular plates.

[0018] Beneficial effects

[0019] This utility model provides a remote sensing measurement device for steel bar dimensions. It has the following beneficial effects:

[0020] 1. The remote sensing measurement device for steel bar dimensions drives a second pressure roller to rotate via a drive motor. Since the circumferential surface of the second pressure roller has a spiral extrusion groove, the second pressure roller will exert a force on the circumferential direction of the steel bar when it rotates, which can realize the rotation of the steel bar, facilitate the adjustment of the measured position of the steel bar, and improve the measurement accuracy.

[0021] 2. This remote sensing measurement device for rebar dimensions uses a tension spring to pull down the ear plate, causing the vertical plate and ear plate to move downward within the corresponding first limiting groove. This allows the first and second pressure rollers to approach the bottom of the support roller, thereby limiting the rebar and suppressing vertical jumping of the rebar during transportation, ensuring stable transport and imaging. At the same time, the adjustable positions of the first and second pressure rollers can adapt to rebars of different diameters within a certain range, providing better flexibility and adaptability.

[0022] 3. This remote sensing measurement device for steel bar dimensions uses two symmetrically arranged side guide rollers to approach and push the steel bar, and a spring pushes a slider to slide in the second limiting groove so that the side guide rollers approach the other side guide roller, thereby suppressing the steel bar from shifting and swaying on the horizontal plane and further improving the stability of transportation.

[0023] 4. This remote sensing measurement device for steel bar dimensions, by setting lateral limiting components and top limiting components, and cooperating with rollers to lift the steel bar at the bottom, can form limiting around the steel bar, which can not only ensure the stability of steel bar transportation, but also allow the steel bar to rotate and adjust the measured position during transportation, thus expanding its functionality.

Detailed Implementation

[0031] A remote sensing measurement device for steel bar dimensions, such as Figure 1 and Figure 2 As shown, it includes:

[0032] The base 10 has a conveying groove 11 on its top. A roller 12 for supporting the reinforcing bars is rotatably connected inside the conveying groove 11. A crossbeam 13 is fixedly installed on the top of the base 10. An electric actuator 14 is fixedly installed on the top of the crossbeam 13. A remote sensing probe 15 for measurement is fixedly installed on the output shaft of the electric actuator 14. The remote sensing probe 15 needs to be connected to an external computer. The computer software analyzes the image of the reinforcing bars captured by the remote sensing probe 15 to measure the parameters of the reinforcing bars. This is suitable for the rapid measurement of reinforcing bar parameters by engineering supervisors. This is a well-known existing technology and will not be described in detail here.

[0033] like Figure 1 , Figure 4 and Figure 6 As shown, a top limiting assembly is set above the base 10 to limit the movement of the reinforcing bar. The top limiting assembly includes a first pressure roller 20, a second pressure roller 22, an extrusion groove 23, and a drive motor 24. The first pressure roller 20 and the second pressure roller 22 are elastically connected to the base 10 through connectors. The second pressure roller 22 has an extrusion groove 23. The output shaft of the drive motor 24 is fixedly connected to the extrusion groove 23 to drive the second pressure roller 22 to rotate. Several first pressure rollers 20 and second pressure rollers 22 are alternately arranged on the top of the base 10. The extrusion groove 23 can push the reinforcing bar to rotate. The first pressure roller 20 and the second pressure roller 22 have the same shape. The two ends of the first pressure roller 20 are circular plates, and the middle part of the first pressure roller 20 is a cylinder with a diameter smaller than that of the circular plates. The extrusion groove 23 is opened in the middle part of the second pressure roller 22 and is spiral in shape.

[0034] In this scheme, the reinforcing bar is supported by the roller 12 at the bottom of the conveying trough 11. A motor is fixedly installed on one side of the base 10, and the roller 12 is fixedly connected to the output shaft of the motor. The roller 12 rotates to push and support the reinforcing bar. However, the reinforcing bar moves in a straight line when it is pushed, so the remote sensing probe 15 can only capture the upper half of the reinforcing bar. The side of the reinforcing bar facing the bottom of the base 10 is difficult to capture, which will affect the measurement of the reinforcing bar. The second pressure roller 22 is driven to rotate by the drive motor 24. Since the second pressure roller 22 has a spiral extrusion groove 23 on its circumferential surface, the second pressure roller 22 will exert a force on the circumferential direction of the reinforcing bar when it rotates, which can realize the rotation of the reinforcing bar, making it easier to adjust the measured position of the reinforcing bar and improve the measurement accuracy.

[0035] like Figure 3 and Figure 4 As shown, the connector includes a vertical plate 30, an ear plate 31, and a tension spring 32. The vertical plate 30 is slidably connected to the base 10, the ear plate 31 is fixedly connected to the vertical plate 30, and the tension spring 32 is fixedly installed at the bottom of the ear plate 31 and fixedly connected to the base 10. The top of the base 10 is provided with a plurality of first limiting grooves 16. The vertical plate 30 and the ear plate 31 are slidably disposed in the first limiting grooves 16. The vertical plate 30 is a rectangular plate, and the ear plate 31 is a trapezoidal block. The ear plate 31 is fixedly disposed on one side of the vertical plate 30. The joint formed by the vertical plate 30 and the ear plate 31 is adapted to the first limiting grooves 16.

[0036] To enable the installation of the first pressure roller 20 and the second pressure roller 22, the first pressure roller 20 and the second pressure roller 22 are rotatably connected to two vertical plates 30 respectively. The ear plate 31 is pulled down by the tension spring 32, causing the vertical plate 30 and the ear plate 31 to move down in the corresponding first limiting groove 16. As a result, the first pressure roller 20 and the second pressure roller 22 can approach the bottom of the support roller 12 to limit the movement of the steel bar, suppress the vertical jumping of the steel bar during the conveying process, and ensure the stability of the transport and shooting. At the same time, the adjustable position of the first pressure roller 20 and the second pressure roller 22 can adapt to steel bars of different diameters within a certain range, and has better flexibility and adaptability in use.

[0037] like Figure 1 , Figure 3 and Figure 5 As shown, a lateral limiting component is disposed on the top of the base 10 for limiting the steel bar laterally;

[0038] The lateral limiting assembly includes a side guide roller 21, a slider 40, and a spring 41. The slider 40 is fixedly connected to the side guide roller 21, and the slider 40 is elastically connected to the base 10 through the spring 41. A second limiting groove 17 is provided on the inner bottom surface of the base 10. The slider 40 is slidably disposed in the second limiting groove 17. One end of the spring 41 is fixedly connected to the slider 40, and the other end of the spring 41 is fixedly connected to the base 10. Several side guide rollers 21 are provided on the inner walls of both sides of the roller 12. Two side guide rollers 21 in symmetrical positions clamp the limiting steel bar together.

[0039] In order to create a limit on both sides of the steel bar, two symmetrically arranged side guide rollers 21 are brought close to and squeezed the steel bar. The spring 41 pushes the slider 40 to slide in the second limit groove 17, so that the side guide roller 21 moves close to the other side guide roller 21, suppressing the steel bar from shifting and swaying on the horizontal plane, and further improving the stability of transportation.

[0040] By setting lateral limiting components and top limiting components, and with the idler roller 12 supporting the bottom of the steel bar, the steel bar can be limited on all four sides. This not only ensures the stability of steel bar transportation, but also allows the steel bar to rotate and adjust the measured position during transportation, thus expanding its functionality.

[0041] The working principle of this utility model is as follows: The tension spring 32 pulls down the ear plate 31, causing the vertical plate 30 and the ear plate 31 to move down in the corresponding first limiting groove 16. As a result, the first pressure roller 20 and the second pressure roller 22 can approach the bottom of the support roller 12 to limit the movement of the steel bar and suppress the vertical jumping of the steel bar during the conveying process. The support roller 12 at the bottom of the conveying groove 11 lifts the steel bar. A motor is fixedly installed on one side of the base 10. The support roller 12 is fixedly connected to the output shaft of the motor. The support roller 12 rotates to push and lift the steel bar. When the steel bar is pushed, it moves in a straight line. As a result, the remote sensing probe 15 can only capture the image of the upper half of the steel bar. The second pressure roller 22 is driven to rotate by the drive motor 24. Since the second pressure roller 22 has a spiral extrusion groove 23 on its circumferential surface, the second pressure roller 22 will exert a force on the circumferential direction of the steel bar when it rotates, which can realize the rotation of the steel bar and adjust the measured position of the steel bar.

Those skilled in the art should understand that this utility model is not limited to the above embodiments.
