Description

Technical Field

[0001] The utility model relates to the technical field of mechanical detection equipment, in particular to a container corner positioning detection device. Background Art

[0002] During the process of loading and transporting containers, they are usually loaded on the main deck or hatch cover, and are stacked up on the corners. As the automation of container loading continues to increase, when stacking, the positioning marks of the corners of the containers are usually obtained through image acquisition devices such as cameras, and then the positions to be stacked are confirmed through the positioning marks.

[0003] Due to the influence of the humid environment, the positioning marks on the corners of the container will corrode and disappear, making it impossible to confirm the position of the stacking. At the same time, due to corrosion, there will be rust residue on the corners of the container, making it difficult for the strong magnet to firmly adsorb the steel tape measure on the corners of the container, so that the steel tape measure cannot be used to achieve positioning. Therefore, when the corners of the container are corroded and the positioning marks cannot be accurately identified, the corners of the container need to be cut and replaced.

[0004] At present, when replacing the box corner, it is usually necessary to manually find and re-carve the actual center positioning line of the inner edge hole of the box corner. In this way, at least two people are required to use a ruler to measure the positioning size of the box corner. This method is not only labor-intensive and difficult to implement, but also its measurement accuracy is greatly affected by the experience of personnel, and the accuracy of the measurement cannot be guaranteed.

For example, a process, method, system, product or device that includes a series of steps or units is not necessarily limited to those steps or units clearly listed, but may include other steps or units that are not clearly listed or inherent to these processes, methods, products or devices.

[0028] The utility model provides a container corner positioning inspection device, such as Figure 1 As shown, it includes a base 200 and an inspection module 300; the base 200 is used to be installed in conjunction with the container corner 100; the inspection module 300 includes a measurer 310 and a receiver 320; the measurer 310 and the receiver 320 are respectively used to be connected to the base 200; the measurer 310 emits a test light, the receiver 320 receives the test light, and the receiver 320 obtains inspection data according to the received test light; or, the measurer 310 emits and receives the test light, the receiver 320 reflects the test light, and the measurer 310 obtains inspection data according to the received reflected test light.

[0029] The container corner positioning inspection device provided in this embodiment can obtain inspection data between the four corners of the container in pairs by using a measuring device 310 and a receiver 320 in combination, and then can accurately obtain the inner edge center position of the corner according to the measured inspection data, so that one person can easily operate to obtain the actual center positioning line of the inner edge hole of the corner, thereby solving the problems of large workload, high difficulty and unreliable accuracy of the existing corner measurement and positioning methods.

[0030] Specifically, in practical applications, such as Figure 2 As shown, the top of the container corner 100 has an inner edge hole 110. The shape of the inner edge hole 110 is not necessarily a regular circle or square, but is usually as follows Figure 2The rectangle with rounded edges shown is very difficult to find the center of the inner edge hole 110 by manual positioning.

[0031] To this end, the base 200 provided in this embodiment is as follows: Figure 3 As shown, it includes a base plate 210 and a base foot 220 located at the bottom of the base plate 210; the base foot 220 is used to be clamped on the side wall of the inner edge hole 110 of the corner of the container to fix the base plate 210.

[0032] In the specific implementation process, the shape of the base 200 and the position of the base foot 220 relative to the base plate 210 can be designed according to the shape and size of the inner edge hole 110 of the container corner, so that when the base 200 is placed in the inner edge hole 110, the base 200 will not shake, and the plane where the base plate 210 is located is parallel to the plane where the top of the corner 100 is located. Specifically, the stainless steel plate can be cut and processed by laser cutting and laser welding to form the base plate 210 and the base foot 220 respectively, and then welded to form the base 200.

[0033] Preferably, in this embodiment, in order to improve the stability of the base 200, the number of the base legs 220 is multiple, for example, 4. At the same time, the multiple base legs 220 need to be symmetrically distributed around the center of the base plate 210.

[0034] More preferably, in order to facilitate the subsequent confirmation of the position of the corner positioning point, in this embodiment, the center of the base plate 210 and the center of the inner edge hole 110 of the container corner are located on the same axis.

[0035] In addition, in order to facilitate the subsequent installation of the measuring device or the receiver and the base 200, the base 200 may also be provided with slots or positioning columns, etc., so as to facilitate the installation of the measuring device and the receiver. Figure 3 As shown, the center position of the base plate 210 is provided with a mounting hole symmetrically arranged along the central axis for matching and mounting with a measuring device or a receiver. In this way, the mounting efficiency of the base 200 and the measuring device or the receiver can be effectively improved, and the mounting complexity can be reduced.

[0036] Furthermore, in this embodiment, if Figure 4 As shown, the measuring device 310 includes a first fixed frame 311, a first rotating mechanism 312 and a rangefinder 313; the bottom of the first fixed frame 311 is fixedly connected to the base 200; the rangefinder 313 is rotatably arranged on the upper part of the first fixed frame 311 through the first rotating mechanism 312, and the rangefinder 313 is used to emit test light.

[0037] Specifically, in this embodiment, if Figure 5 As shown, the first fixing member 311 includes a base plate and two base feet located at the bottom of the base plate. The base feet used in this embodiment match the mounting holes on the base plate 210, so that the base feet can be embedded in the mounting holes of the base plate 210, thereby fixing the measuring device 310. The first rotating mechanism 312 includes a cap nut and a rotating shaft, through which the rangefinder 313 can be rotated relative to the first fixing member 311, and the cap nut is used to press the rangefinder 313 to the first fixing member 311 to ensure that it will not loosen in the vertical direction. In addition, in order to facilitate the rotatable installation of the micro laser rangefinder on the first fixing member 311, in this embodiment, the rangefinder 313 includes a micro laser rangefinder, and a rangefinder fixing frame and a rangefinder base plate seat for fixing the micro laser rangefinder.

[0038] In order to obtain the distance between the centers of the inner edge holes of the container corners and reduce the amount of calculation for the location of the positioning points in the later stage, in this embodiment, when the measuring device 310 is located on the base 200, the emission point and / or the receiving point of the test light are located on the central axis of the inner edge hole 110 of the container corner. Figure 5 It can be seen that the emission point (receiving point) of the micro laser rangefinder for emitting the test light, the hole on the rangefinder base plate that matches the shaft, the shaft, the center of the base plate, and the center of the two feet of the base all coincide. In this way, when the measuring device 310 is installed on the base 200, and the base 200 is installed in the inner edge hole 110, the emission point (receiving point) of the micro laser rangefinder for emitting the test light will be located on the central axis of the inner edge hole 110 of the container corner.

[0039] Furthermore, in this embodiment, when the receiver 320 is used to receive the test light, the receiver 320 includes a second fixed frame 321, a second rotating mechanism 322 and a light receiving instrument 323; the bottom of the second fixed frame 321 is fixedly connected to the base 200; the light receiving instrument 323 is rotatably arranged on the upper part of the second fixed frame 321 through the second rotating mechanism 322, and the light receiving instrument 323 is used to receive the test light.

[0040] Similar to the setting principle of the measuring device 310, when the receiver 320 is located on the base 200, the light receiving point of the light receiving instrument 323 is located on the central axis of the inner edge hole 110 of the corner of the container.

[0041] Alternatively, in this embodiment, when the receiver 320 is used to reflect the test light, the receiver 320 includes a third fixed frame 321, a third rotating mechanism 322 and a reflective target 323; the bottom of the third fixed frame 321 is fixedly connected to the base 200; the reflective target 323 is rotatably arranged on the upper part of the third fixed frame 321 through the third rotating mechanism 322, and the reflective target 323 is used to reflect the test light.

[0042] Likewise, when the receiver 320 is located on the base 200 , the reflective point of the reflective target 323 is located on the central axis of the inner edge hole 110 of the corner of the container.

[0043] In this embodiment, the structure of the light receiver 320 is specifically described by taking the light receiver 320 used for reflecting the test light as an example, that is, it includes a reflection target. Figure 6 As shown, the receiver 320 includes a third fixed frame 321, a third rotating mechanism 322 and a reflective target 323; the bottom of the third fixed frame 321 is fixedly connected to the base 200; the reflective target 323 is rotatably arranged on the upper part of the third fixed frame 321 through the third rotating mechanism 322, and the reflective target 323 is used to reflect the test light.

[0044] Specifically, in this embodiment, if Figure 7 As shown, the third fixing frame 321 includes a receiver base plate and two base feet located at the bottom of the receiver base plate. The two base feet used in this embodiment match the mounting holes on the base plate 210, so that the two base feet can be embedded in the mounting holes of the base plate 210, thereby fixing the receiver 320. The third rotating mechanism 322 also includes a cap nut and a rotating shaft, through which the reflecting plate 323 can be rotated relative to the third fixing frame 321. At the same time, the reflecting plate 323 is pressed against the third fixing frame 321 by the cap nut to ensure that it will not loosen in the vertical direction. The reflecting surface of the reflecting target 323 is located at the center of the rotating shaft, so that when the receiver 320 is located on the base 200, the point of the test light reflected by the reflecting target 323 is located on the central axis of the inner edge hole 110 of the corner of the container. From Figure 7 It can be seen that the reflective surface of the reflective target 323, the rotating shaft, the center of the base plate and the center of the two feet of the base all coincide. In this way, when the receiver 320 is installed on the base 200 and the base 200 is installed in the inner edge hole 110, the point of the test light reflected by the reflective target 323 will be located on the central axis of the inner edge hole 110 of the container corner. In this way, it is easy to obtain the distance between the centers of the inner edge holes of the container corner, so as to reduce the amount of calculation for calculating the location point position in the later stage.

[0045] When the container corner positioning inspection device provided by the present embodiment is used for positioning inspection, first, a matching base 200 and related fixing accessories are manufactured according to the size rule of the inner edge hole 110 of the corner; then, the base 200 is installed on all the corners to be measured on site, and a measuring device 310 is installed on one of the bases 200, and a receiver 320 is installed on the other bases 200; then, the measuring device 310 is rotated so that the test light emitted by the micro laser rangefinder 313 is aligned with the reflective target 323 on the receiver 320 in turn, so that the micro laser rangefinder 313 receives the reflected test light, thereby obtaining the distance between the two, which represents the distance between the center of the inner edge hole 110 where the measuring device 310 is installed and the center of the inner edge hole 110 where the receiver 320 is installed; the above steps are repeated until the data of all the corners are measured.

[0046] By using the container corner positioning inspection device provided in this embodiment to perform positioning inspection, only one operator is required to easily complete the measurement, and the test results are accurate and reliable.

By using the measurer and the receiver in combination, it is possible to obtain inspection data between the four corners of the container, and then the inner edge center position of the corner can be accurately obtained based on the measured inspection data, so that one person can easily operate to obtain the actual center positioning line of the inner edge hole of the corner, solving the problem of large workload, high difficulty, and unreliable accuracy in the existing corner measurement and positioning methods.
