Description

Technical Field

[0001] The utility model relates to the field of angle steel inspection equipment, in particular to an angle steel inspection device. Background Art

[0002] Angle steel is a key component in the manufacture of steel towers. Holes must be drilled to facilitate subsequent splicing. Therefore, prior to tower assembly, the hole locations, specifications, and quality of the holes must be inspected. Because specialized inspection tools are currently unavailable, inspections currently rely on manual visual inspection with handheld rulers. This method is not only inefficient but also results in significant errors. Utility Model Content

[0003] In response to the above problems, the utility model proposes an angle steel inspection device, which uses a calibration ruler and a detection camera in combination to detect the angle steel and the calibration ruler using the detection camera, thereby increasing the detection efficiency and reducing the detection error.

[0004] The technical solutions adopted by this utility model are as follows:

[0005] An angle steel inspection device includes a base, a guide rail, a sliding seat, a suspension arm, a calibration ruler and a detection camera. The guide rail is arranged on the base, the calibration ruler is arranged on the base, the calibration ruler and the guide rail are in a parallel state, the sliding seat and the guide rail are slidably fitted together, the suspension arm is arranged on the sliding seat, and the detection camera is directly or indirectly arranged on the suspension arm.

[0006] The working process of this inspection device is as follows: first, with the help of other mechanisms (including but not limited to robotic arms), the angle steel is lifted to one side of the base, so that the angle steel is in a state parallel to the guide rail, and the sliding seat moves along the guide rail. During the movement of the sliding seat along the guide rail, the angle steel is photographed by the detection camera. The angle steel image captured by the detection camera is analyzed by the software of the host computer (the image information captured by the detection camera is transmitted to the host computer, and the software in the host computer analyzes it) to determine whether the parameters of the hole of the angle steel (including but not limited to the hole diameter, end distance and standard distance) and other printed marks are qualified. At the same time, since a calibration ruler is also set on the base, the calibration ruler can record the position of the sliding seat (and the suspension arm) on the base. Therefore, when taking pictures, the camera can calculate the position of each hole on the ruler by recording the position of the sliding seat on the base, and finally calculate whether the spacing between two adjacent holes is qualified and whether the length of the angle steel meets the standard.

[0007] In summary, this inspection device uses a calibration ruler and a detection camera in combination, and uses the detection camera to detect the angle steel and the calibration ruler, which has higher detection efficiency and smaller detection error.

[0008] Optionally, a movable motor is further included, wherein the movable motor is arranged on the sliding seat, the base is provided with a rack, and the shaft of the movable motor is matched with the rack through a gear.

[0009] The specific function of the moving motor is to drive the sliding seat to move along the guide rail on the base. The existence of the moving motor can ensure that the sliding seat can move stably along the guide rail on the base.

[0010] Specifically, in this angle steel inspection device, there are two guide rails on the base, the two guide rails are in a parallel state, and the rack is located between the two parallel guide rails. The rack is located between the two guide rails, so that the gear on the moving motor is also located between the two guide rails.

[0011] Optionally, a mounting cover is further included, the detection camera is arranged on the mounting cover, and the mounting cover is provided with a fill light.

[0012] The function of the mounting cover is to protect the inspection camera and the fill light. To ensure that the inspection camera and the fill light have good working efficiency during the photo shooting operation, a mounting rod is set in the mounting cover. The inspection camera is a cylindrical inspection camera, and the fill light is a ring-shaped fill light. The light emitted by the fill light is distributed around the inspection camera. The position of the inspection camera and the fill light on the mounting rod can be adjusted as needed.

[0013] Optionally, the suspension arm is perpendicular to the guide rail.

[0014] Optionally, there are multiple detection cameras, and each detection camera is respectively arranged at a different position of the suspension arm.

[0015] The purpose of setting up multiple inspection cameras is to take pictures of different objects. Some inspection cameras are used to take pictures of angle steels. The cameras that take pictures of angle steels are used to obtain the image information of angle steels, while some cameras are used to take pictures of calibration rulers. Assuming that the inspection camera used to take pictures of angle steels is A, and the inspection camera used to take pictures of calibration rulers is B, when A takes pictures of the angle steels (at this time the sliding seat is in a stationary state relative to the base), B takes pictures of the calibration rulers, thereby recording the position of the sliding seat on the calibration ruler, thereby indirectly calculating the position of the holes on the calibration ruler, and finally calculating the spacing of the holes by recording the position of each hole on the calibration ruler. At the same time, the above method is used to calculate the length of the angle steel, and the rest is obtained through the angle cutting of the angle steels, the parameters of the holes, and whether the marks are qualified through the image information taken by A and analyzed by the software of the upper computer.

[0016] Specifically in this device, in order to ensure that each detection camera can operate stably, each detection camera is used with a mounting cover and a fill light.

[0017] Specifically in this inspection device, in order to distinguish the detection cameras with different functions,

[0018] Optionally, it further includes a screw module, which is arranged on the suspension arm, and the detection camera is arranged on the slider of the screw module.

[0019] Specifically in this inspection device, there are two screw modules, both of which are installed on the suspension arm. A connecting plate is installed on the slider of each screw module, and each connecting plate is provided with a mounting cover. A detection camera is provided in each mounting cover. In order to ensure that both sides of the angle steel can be completely photographed by the detection camera, the directions of the detection cameras on the two screw modules are distributed at a 90-degree angle.

[0020] Specifically, in this inspection device, the inspection camera for taking pictures of the calibration ruler is set on the suspension arm, and the inspection camera for taking pictures of the angle steel is set on the connecting plate.

[0021] Optionally, a drag chain groove is further included, which is arranged on one side of the base and is parallel to the guide rail.

[0022] Specific drag chain troughs can be used to place drag chains.

[0023] Optionally, the sliding seat is provided with a sliding limit block, the sliding limit block is slidably matched with the guide rail, the guide rail is provided with a recess, the sliding limit block is provided with a protrusion, and the protrusion is matched with the recess.

[0024] The beneficial effects of the present invention are as follows: by using the calibration ruler and the detection camera in combination, the angle steel and the calibration ruler are detected by the detection camera, so the detection efficiency is higher and the detection error is small.
