Description

Technical Field

[0001] The present invention relates to the technical field of quality inspection equipment, and in particular to a fully automatic high-precision intelligent size inspection equipment and a inspection method for concrete pipes. Background Art

[0002] Reinforced concrete pipe is a drainage pipe made of reinforced concrete in a factory through a prefabricated process. It is mainly used to build municipal rainwater and sewage drainage systems. This type of pipe plays an important role in urban infrastructure construction because of its durability and strong adaptability. In order to ensure the smooth docking of the pipe during installation and the stable performance in long-term use, the dimensional accuracy of the pipe is particularly important. The accuracy of the pipe size directly affects the quality and efficiency of the construction, as well as the safety of subsequent use.

[0003] However, in the actual production process, the traditional method of detecting pipe dimensions mainly relies on manual measurement using tools such as rulers. Although this approach is intuitive and simple, it requires a lot of manpower, which is not only inefficient, but also easily affected by the individual skill differences of operators during the measurement process, resulting in inaccurate measurement results. In addition, manual inspection may also miss inspections of certain parts due to negligence, thus affecting overall quality control. Therefore, how to improve detection efficiency and accuracy has become one of the key issues that need to be solved in this field. Summary of the invention

[0004] The technical problem to be solved by the present invention is to provide a fully automatic high-precision intelligent size detection device and a detection method for concrete pipes.

[0005] In order to solve the above technical problems, the technical solution of the present invention is:

[0006] A fully automatic high-precision intelligent size detection device and detection method for concrete pipes, comprising a gantry, a laser rangefinder, a controller, an alarm, a translation track, and an electric translation vehicle installed on the translation track in a rolling manner; the two sides of the gantry are fixedly connected to the two sides of the translation track; the laser rangefinder is in two sets, which are respectively arranged on the two sides of the gantry, and the measuring end of the laser rangefinder points to the middle of the concrete pipe to be measured; the controller is electrically connected to the laser rangefinder and the alarm respectively; the upper end of the electric translation vehicle is equipped with a support frame for carrying the concrete pipe.

[0007] Preferably, it also includes two sets of thickness gauges electrically connected to the controller, the thickness gauges are respectively arranged on both sides of the gantry, the measuring ends of the thickness gauges are at the same height as the measuring ends of the laser rangefinder and point to the middle of the concrete pipe to be measured.

[0008] Preferably, the alarm is fixedly connected to the upper end of the door frame.

[0009] Preferably, the door frame is fixedly connected to the translation track via a connecting plate; and a rib plate is provided at the connection between the connecting plate and the translation track.

[0010] Preferably, the support frame includes a bracket fixedly connected to the electric translation vehicle, and a support plate fixedly connected to the upper end of the bracket and having an upper surface in a concave arc shape.

[0011] A detection method of the fully automatic high-precision intelligent size detection device for concrete pipes as described above, characterized in that the detection steps are as follows:

[0012] S1. Place the concrete pipe horizontally on the electric translation vehicle using a lifting device;

[0013] S2. The electric translation vehicle approaches the gantry at a constant speed along the translation track;

[0014] S3. The laser rangefinder and thickness gauge installed on both sides of the gantry measure the concrete pipe passing through the gantry at a uniform speed. The controller receives the measurement data of the laser rangefinder and thickness gauge, and determines the diameter and thickness of the concrete pipe based on the measurement data. At the same time, the measurement results are immediately displayed on the display screen of the controller. If the measurement results exceed the allowable deviation value, the controller controls the alarm to sound an immediate alarm;

[0015] S4. The electric translation vehicle passes through the gantry along the track and the measurement is completed.

[0016] Preferably, the controller determines in the following manner:

[0017] The distance from the starting point to the center of the concrete pipe measured by the laser rangefinder is L1. The standard inner diameter value of the concrete pipe is d, the standard outer diameter value is D and the standard thickness value is H. The laser rangefinder measures the distance from it to the outer wall of the concrete pipe is L2, and the thickness gauge measures H1. Assume that the outer diameter deviation value, inner diameter deviation value and thickness deviation value of the concrete pipe are ±D0, ±d0 and ±H0 respectively. The following judgments are performed in sequence:

[0018] Judgment 1: When the absolute value of L1-L2-D is less than or equal to D0, the outer diameter is qualified and judgment 2 is continued; otherwise, the outer diameter is unqualified, the judgment is ended and an alarm is issued;

[0019] Judgment 2: When the absolute value of L1-L2-H1-d is less than or equal to d0, the inner diameter is qualified and judgment 3 is continued; otherwise, the inner diameter is unqualified, the judgment is terminated and an alarm is issued; L2 and H1 in judgment 2 are the point values ​​of the same point on the concrete pipe;

[0020] Judgment three: When the absolute value of H1-H is less than or equal to H0, the wall thickness is qualified and it is judged as a qualified product; otherwise, the wall thickness is unqualified, the judgment is ended and an alarm is issued.

[0021] Preferably, the point values ​​of L2 and D at the same point on the concrete pipe are calculated as follows:

[0022] Obtain the center distance S between the measuring end of the laser rangefinder and the measuring end of the thickness gauge, and obtain the moving speed V of the electric translation vehicle. T=S / V is the time required for the same point on the concrete pipe to move from the center of the measuring end of the laser rangefinder to the center of the measuring end of the thickness gauge, or the time required for the same point on the concrete pipe to move from the center of the measuring end of the thickness gauge to the center of the measuring end of the laser rangefinder. At this time, according to the value of T and the arrangement relationship between the laser rangefinder and the thickness gauge, the obtained values ​​of L2 and D can be matched.

[0023] The above technical solution has the following advantages:

[0024] The present invention provides a detector that can realize automatic and continuous detection of the diameter and wall thickness of reinforced concrete pipes. By adopting continuous automated detection means, the detection task can be completed efficiently, and the detection efficiency is significantly improved. Compared with the traditional manual detection method, this automated detection method not only reduces the demand for manpower and reduces labor costs, but also greatly improves the consistency and accuracy of the detection. Since the detection process no longer relies on manual operation, it can effectively avoid errors caused by human factors, such as missed detection, and thus ensure that each section of concrete pipe can meet the design standards and meet high-quality construction requirements. In addition, the automated detection system can also reduce the potential risks caused by inaccurate or incomplete detection, thereby providing strong technical support for the construction and maintenance of municipal rainwater and sewage discharge systems.

[0041] Example 2

[0042] A detection method of the fully automatic high-precision intelligent size detection device for concrete pipes as described in Example 1, wherein the detection steps are as follows:

[0043] S1. Use a lifting device to place the concrete pipe 20 horizontally on the electric translation vehicle 6;

[0044] S2. The electric translation vehicle 6 approaches the gantry 1 at a constant speed along the translation track 5;

[0045] S3. The laser rangefinder 2 and the thickness gauge 7 arranged on both sides of the gantry 1 measure the concrete pipe 20 passing through the gantry 1 at a uniform speed. The controller 3 receives the measurement data of the laser rangefinder 2 and the thickness gauge 7, and determines the diameter and thickness of the concrete pipe 20 according to the measurement data. At the same time, the measurement result is immediately displayed on the display screen of the controller 3. If the measurement result exceeds the allowable deviation value, the controller 3 controls the alarm 4 to immediately alarm;

[0046] S4. The electric translation vehicle 6 passes through the gantry 1 along the track, and the measurement is completed.

[0047] In this embodiment, the determination method of the controller 3 is as follows:

[0048] The distance from the starting point of the laser rangefinder 2 to the center of the concrete pipe 20 is L1, the standard inner diameter value (design value, the same as the rest) of the concrete pipe 20 is d, the standard outer diameter value is D and the standard thickness value is H, the laser rangefinder 2 measures the distance L2 from the outer wall of the concrete pipe 20, and the thickness gauge 7 measures H1. Assuming that the outer diameter deviation value of the concrete pipe 20 is allowed to be ±D0, the inner diameter deviation value is ±d0, and the thickness deviation value is ±H0; the following judgments are performed in sequence:

[0049] Judgment 1: When the absolute value of L1-L2-D is less than or equal to D0, the outer diameter is qualified and judgment 2 is continued; otherwise, the outer diameter is unqualified, the judgment is ended and an alarm is issued;

[0050] Judgment 2: When the absolute value of L1-L2-H1-d is less than or equal to d0, the inner diameter is qualified and judgment 3 is continued; otherwise, the inner diameter is unqualified, the judgment is terminated and an alarm is issued; L2 and H1 in judgment 2 are point values ​​of the same point on the concrete pipe (20);

[0051] Judgment three: When the absolute value of H1-H is less than or equal to H0, the wall thickness is qualified and it is judged as a qualified product; otherwise, the wall thickness is unqualified, the judgment is ended and an alarm is issued.

[0052] In this embodiment, L2 and D are the point values ​​of the same point on the concrete pipe 20, and the calculation method is as follows:

[0053] Obtain the center distance S between the measuring end of the laser rangefinder 2 and the measuring end of the thickness gauge 7, and obtain the moving speed V of the electric translation vehicle 6. T=S / V is the time required for the same point on the concrete pipe 20 to move from the center of the measuring end of the laser rangefinder 2 to the center of the measuring end of the thickness gauge 7, or the time required for the same point on the concrete pipe 20 to move from the center of the measuring end of the thickness gauge 7 to the center of the measuring end of the laser rangefinder 2. At this time, according to the value of T and the arrangement relationship between the laser rangefinder 2 and the thickness gauge 7, the obtained values ​​of L2 and D can be matched.

[0054] by Figure 6 Taking the detection of the electric translation vehicle 6 moving to the left as an example, the laser rangefinder 2 is on the left side of the thickness gauge 7. The laser rangefinder 2 first obtains the value L2(X) of a certain point X. After a time T, the point X moves to the measuring point of the thickness gauge 7. At this time, the thickness gauge 7 obtains the value D(X) of the point X. There is a time difference T between the two. L2(X) and D(X) with the time difference are the point values ​​of the same point X on the concrete pipe 20.

[0055] The present invention continuously detects the concrete pipe 20 through the laser rangefinder 2 and the thickness gauge 7, can efficiently complete the detection task, and significantly improves the detection efficiency.

For those skilled in the art, various changes, modifications, substitutions and variations of these embodiments are made without departing from the principles and spirit of the present invention, and still fall within the scope of protection of the present invention.
