Description

Technical Field

[0001] This invention relates to measuring devices, and more particularly to a measuring device for indicating the end position of a steel plate. Background Technology

[0002] Currently, steel products include various types such as horizontal coils, vertical coils, and thick plates. Each type of product has different dimensions, and the hoisting conditions are complex and varied, which places high demands on the hoisting capacity of bridge-type ship loaders.

[0003] In the busy operations of port logistics, the hoisting of extra-long and thick plates is an extremely challenging task. This is because the length of the extra-long and thick plates is close to the distance between the two outriggers of the bridge ship loader, and abnormal situations such as the thick plates rubbing against the outriggers are very likely to occur during the hoisting process.

[0004] Generally, plates exceeding 25 meters in length are considered extra-long and thick plates. The distance between the two outriggers of a bridge-type ship loader is 27 meters. To avoid major accidents such as plates colliding with the outriggers during hoisting, extra-long and thick plates require manual measurement before hoisting. Taking a 26.8-meter-long extra-long and thick plate as an example, with an 18-meter-long lifting beam placed on the plate, the distance from each end of the plate to the end of the lifting beam is 4.4 meters, and the distance from the end of the plate to the outrigger is 0.1 meters. During measurement, due to external environmental factors and human error, even a slight error can lead to a collision between the plate and the outrigger during hoisting, resulting in a major safety accident, and in severe cases, the collapse of the bridge-type ship loader.

[0005] It is evident that the hoisting of extra-long, wide, and thick plates is not only related to the efficient flow of goods, but also directly to the safety of workers and the integrity of equipment and facilities.

[0006] Currently, when hoisting extra-long, thick plates, multiple manual measurements are required to confirm that the lifting beam is positioned in the middle of the plate before lifting it. Personnel are stationed at the outriggers on both sides of the bridge-type ship loader to dynamically inspect the situation. If the extra-long, thick plate is about to collide with the outriggers, work is immediately stopped, the plate is placed back on the frame, and measurements and adjustments are made before further hoisting. These multiple measurements and adjustments severely limit the operational efficiency of the dockside bridge-type ship loader equipment. Summary of the Invention

[0007] The purpose of this invention is to provide an adjustable width indicator device for hoisting ultra-long and thick plates. This device can accurately mark the end position of the ultra-long and thick plates, thereby guiding the trolley of the bridge ship loader to move to a suitable hoisting position. This effectively ensures the safe and efficient hoisting of ultra-long and thick plates, thus significantly improving hoisting efficiency, ensuring the safety of hoisting operations, and greatly reducing the workload of operators.

[0008] To achieve the above objectives, the present invention proposes an adjustable width indication device for hoisting ultra-long, wide, and thick plates. This device is mounted on a hoisting device and includes at least two width indication components corresponding to both ends of the length of the ultra-long, wide, and thick plate. Each width indication component includes:

[0009] The track extends along the length of the extra-long, wide, and thick plate;

[0010] A mobile cart, which is configured to move along a track;

[0011] A drive unit, which is connected to the traveling trolley, to drive the traveling trolley to move along the track;

[0012] A laser emitter is fixedly mounted on a traveling trolley and emits a laser beam toward an extra-long, wide, and thick plate to mark the length end face of the plate.

[0013] The rangefinder is fixedly mounted on the traveling trolley;

[0014] Among them, the two distance measuring instruments of the two width measuring components detect the distance between the two traveling trolleys as they move along the track.

[0015] The invention applies laser positioning technology to bridge-type ship loader operations. Adjustable width-indicating devices, as described in this invention, are installed at both ends of the bridge-type ship loader's crossbeam. These devices use laser emitters to project powerful laser beams onto extra-long, wide, and thick plates, marking their length end faces. A rangefinder moves relative to or away from the trolley along the track. During relative movement, the distance between the two laser emitters decreases; during separation, the distance increases. This adjustable width-indicating device accurately displays the position of the extra-long, wide, and thick plate under the bridge-type ship loader, ensuring alignment between the plate and the loader and enabling safe and efficient lifting operations.

[0016] During operation, once the extra-long, wide, and thick plate is transported to the designated position under the bridge-type ship loader, the traveling trolleys are positioned along the track according to the plate's length. The relative distance between the traveling trolleys is adjusted so that the distance detected by the rangefinder matches the plate's length. At this point, the operator moves the bridge-type ship loader's main trolley. The powerful laser beams emitted by the two laser emitters strike both ends of the extra-long, wide, and thick plate, indicating that the plate is positioned between the two outriggers of the bridge-type ship loader, and the lifting beam is centered on the plate—that is, the lifting beam and the plate are aligned. The operator then lowers the lifting beam, installs the plate hooks, and completes the safe lifting operation of the extra-long, wide, and thick plate. Since the plate's length matches the distance between the two outriggers, it can pass smoothly through the outriggers without collision, thus achieving safe lifting.

[0017] Furthermore, the adjustable width indicator device of the present invention also includes a control device, which is data connected to each of the rangefinders and each drive device respectively, so as to send control signals to them and receive data from the rangefinders.

[0018] Furthermore, in the adjustable width display device of the present invention, each width display component also includes a wireless communication device, which is connected to the corresponding driving device and control device, and is also connected to the corresponding rangefinder and control device.

[0019] Furthermore, in the adjustable width indicator device of the present invention, the control device further includes a display module that displays the distance between the two traveling trolleys.

[0020] Furthermore, in the adjustable width display device of the present invention, each driving device includes a motor and a transmission assembly, wherein the rotating shaft of the motor is connected to the transmission assembly, and the transmission assembly is connected to the traveling trolley.

[0021] Furthermore, in the adjustable width indicator device of the present invention, the transmission component includes a lead screw structure.

[0022] Furthermore, in the adjustable width measuring device of the present invention, the rangefinder includes a laser rangefinder.

[0023] Furthermore, in the adjustable width indicator device of the present invention, a laser ranging positioning plate is fixedly provided at the end of the track. The laser rangefinder can measure the position of the laser rangefinder and the traveling trolley on which it is installed by emitting a laser to the laser ranging positioning plate.

[0024] Furthermore, in the adjustable width indicator device of the present invention, the end of the track is provided with a limiting structure to prevent the trolley from detaching from the track.

[0025] The adjustable width indicator device for hoisting ultra-long and thick plates described in this invention can accurately mark the end position of ultra-long and thick plates, thereby guiding the trolley of the bridge ship loader to move to a suitable hoisting position, effectively ensuring the safe and efficient hoisting of ultra-long and thick plates. This not only significantly improves hoisting efficiency but also ensures the safety of hoisting operations and greatly reduces the workload of operators.

[0026] The adjustable width indicator device for hoisting ultra-long and thick plates described in this invention effectively avoids the problem of falling due to swaying, displacement, and collision caused by inaccurate manual measurement of the hoisting plate position deviation, thus ensuring the safety and stability of the entire hoisting process of ultra-long and thick plates.

[0027] The adjustable width indicator device for hoisting ultra-long, wide, and thick plates described in this invention improves operational efficiency through automated control and is less susceptible to interference from environmental factors.

[0028] The adjustable width indicator device for hoisting ultra-long and thick plates described in this invention has high measurement accuracy and is not affected by the operator's experience, concentration, or fatigue.

[0029] The adjustable width indicator device for hoisting ultra-long, wide, and thick plates described in this invention has strong adaptability and can be used for hoisting ultra-long, wide, and thick plates of different sizes and weights, greatly realizing the flexibility and versatility of hoisting operations.

[0031] Figure 2 The diagram shows a schematic representation of a width indicator component in one embodiment of the adjustable width indicator device for hoisting ultra-long, wide, and thick plates according to the present invention. Detailed Implementation

[0032] The adjustable width indicator device for hoisting ultra-long and thick plates described in this invention will be further explained and described below with reference to the accompanying drawings and specific embodiments. However, this explanation and description do not constitute an improper limitation on the technical solution of this invention.

[0033] In some embodiments, the present invention provides an adjustable width indicator for hoisting ultra-long, wide, and thick plates, which is mounted on a hoisting device.

[0034] Figure 1 The image shows the installation state of the adjustable width indicator device for hoisting ultra-long and thick plates according to one embodiment of the present invention on the hoisting device.

[0035] like Figure 1 As shown, an adjustable width indicator device for hoisting ultra-long, wide, and thick plates is installed on the crossbeam P at the bottom of the bridge-type ship loader. The adjustable width indicator device includes at least two width indicator components 1 corresponding to both ends of the length of the ultra-long, wide, and thick plate Q.

[0036] Figure 2 The diagram shows a schematic representation of one embodiment of the adjustable width indicator device for hoisting ultra-long, wide, and thick plates according to the present invention.

[0037] like Figure 2 As shown, in some embodiments, each width-adjusting component 1 includes:

[0038] Track 11 extends along the length of the extra-long, wide, and thick plate. It should be noted that the direction of track extension is parallel to the direction of movement of the bridge-type ship loader trolley.

[0039] The trolley 12 is mounted on the track 11 via rollers 121;

[0040] A drive unit 13 is connected to a traveling trolley 12 to drive the traveling trolley to move along the track 11;

[0041] The laser emitter 14 is fixedly mounted on the traveling trolley 12 and emits a powerful laser beam towards the ultra-long and thick plate to mark the length end face of the ultra-long and thick plate, so that the length end face of the ultra-long and thick plate can be clearly marked both day and night.

[0042] The rangefinder 15 is fixedly mounted on the traveling trolley 12;

[0043] Among them, the two rangefinders 15 of the two width-indicating components 1 detect the distance between the two traveling carts 12 as they move along the track 11.

[0044] When using, such as Figure 1 As shown, after the extra-long and thick plate Q is transported to the designated position under the bridge-type ship loader, the traveling trolley 12 is made to travel along the track 11 according to the specific length of the extra-long and thick plate, for example, 26.8m, so as to adjust the relative distance between the two traveling trolleys 12, so that the distance between the two traveling trolleys detected by the rangefinder 15 is the same as the specific length of the extra-long and thick plate, for example, to adjust the distance between the two traveling trolleys to 26.8m.

[0045] At this point, the operator moves the trolley of the bridge ship loader along the length of the crossbeam Q until the powerful laser beams emitted by the two laser emitters 14 hit the two long end faces of the extra-long and thick plate Q. This indicates that the extra-long and thick plate is now between the two outriggers L of the bridge ship loader, and the position of the bridge ship loader's lifting beam is exactly in the center of the extra-long and thick plate Q, that is, the bridge ship loader's lifting beam is aligned with the extra-long and thick plate.

[0046] At this point, the operator lowers the lifting beam and installs the plate hook to complete the safe hoisting operation of the extra-long and thick plate. The length of the extra-long and thick plate is consistent with the distance between the two ends of the bridge ship loader's outriggers, allowing it to pass smoothly through the two outriggers of the bridge ship loader without collision, thus achieving safe hoisting.

[0047] In some more specific implementations, such as Figure 2 As shown, the adjustable width indicator device of the present invention also includes a control device 16, which is data connected to each rangefinder 15 and each drive device 13 respectively, so as to send control signals to the rangefinder 15 and the drive device 13, and to receive measurement data from the rangefinder.

[0048] In some more specific implementations, such as Figure 2 As shown, each measuring component may also include a wireless communication device 17, and the control device 16 may connect to the corresponding drive device 13 and rangefinder 15 via the wireless communication device 17, such as a WIFI module or Bluetooth module.

[0049] In some more specific implementations, the control device may be configured as a control chip, PLC, or MCU with a wireless communication module.

[0050] In some more specific implementations, such as Figure 2 As shown, the control device may also include a display module that visually displays the distance between the two traveling trolleys to the operator.

[0051] In some more specific embodiments, each drive unit may include a motor and a transmission assembly, with the motor shaft connected to the transmission assembly and the transmission assembly connected to the traveling trolley.

[0052] In some more specific embodiments, the transmission assembly may include a lead screw structure.

[0053] In some more specific embodiments, the rangefinder 15 may include a laser rangefinder.

[0054] In some more specific implementations, such as Figure 2 As shown, a laser rangefinder positioning plate 18 can be fixedly installed at the end of the track 11. The laser rangefinder can measure the position of the laser rangefinder and the traveling trolley on which it is installed by emitting a laser to the laser rangefinder positioning plate 18.

[0055] In some more specific implementations, such as Figure 2 As shown, the end of the track 11 may also be provided with a limiting structure 19, such as a limiting block, to prevent the trolley from detaching from the track.

[0056] In other, more specific embodiments, the limiting structure may also include electronic limiting elements, hydraulic limiting elements, or other limiting structures known to those skilled in the art.

[0057] Therefore, the adjustable width indicator device described in this invention can significantly improve the positioning accuracy and stability of ultra-long and thick plates during hoisting. Through the precise projection of a powerful laser beam, it can clearly mark the edges and dimensions of ultra-long and thick plates in complex environments (rainy, snowy, and foggy days), effectively reducing the problem of inaccurate positioning caused by limited visibility or human judgment errors, and significantly reducing the safety risks caused by position deviations.

[0058] Furthermore, the adjustable width indicator device described in this invention significantly reduces the preparation time for hoisting ultra-long and thick plates. Traditional methods require multiple measurements and adjustments to determine the hoisting point position, while the laser beam width indicator positioning technology of this invention can quickly complete the task by accurately positioning at both ends, greatly shortening the preparation time and improving work efficiency.

[0059] Furthermore, the adjustable width indicator device described in this invention significantly reduces the labor intensity of operators. In traditional hoisting operations, workers need to maintain high concentration and precise operation for extended periods, while the laser beam width indicator positioning device alleviates this burden through automation and intelligence. Personnel only need to operate the control device to achieve high-precision positioning, effectively reducing human error and safety hazards, and improving the safety and reliability of operations.

[0060] From an economic cost perspective, the adjustable width indicator device described in this invention indirectly reduces overall operating costs by improving positioning efficiency. Laser positioning technology completely avoids safety accidents caused by collisions involving ultra-long, thick plates, ensuring the safe operation of the bridge-type ship loader equipment on site.

All technical features described in this case can be freely combined or combined in any way, unless they contradict each other.

[0062] Furthermore, it should be noted that the above examples are merely specific embodiments of the present invention, and the present invention is obviously not limited to the above embodiments, with many similar variations. All modifications that can be directly derived or conceived by those skilled in the art from the disclosure of this invention should fall within the protection scope of this invention.
