Description
Technical Field
[0001] This invention belongs to the field of overhead crane technology, specifically relating to an overhead crane safety control system and control method. Background Technology
[0002] Overhead crane hoisting is a cargo lifting technology based on bridge cranes. Bridge cranes are mechanical devices used to lift heavy objects within a fixed span, widely used in workshops, warehouses, or open-air areas. The main beam of a bridge crane spans across a dedicated track at a certain height within the span, allowing it to move longitudinally along the track. A hoisting device is arranged on the main beam, most often a trolley, which can move laterally along the main beam within the span. Resembling a metal bridge, it is called a bridge crane, also commonly known as a "head crane" or "traveling crane." The hoisting device is used to lift and lower heavy objects and is the most important and fundamental mechanism of a bridge crane. Except for a few beam cranes that use electric hoists, bridge cranes generally use a trolley for their hoisting devices. The trolley consists of a frame, traveling mechanism, hoisting and winding mechanism, and electrical equipment. The frame is supported by four wheels, and the traveling mechanism on the frame drives the wheels to move along the trolley track to achieve lifting at different positions across the span. During operation, the main beam can run along the entire longitudinal direction of the factory building, and the trolley can run laterally on the main beam bridge, forming a rectangular working area within the workshop. Goods are lifted and transported within this rectangular working area by the lifting and winding mechanism.
[0003] There are safety risks during overhead crane operations, including the risk of the hoisted object falling and the risk of interference with the hoisting path. In the relevant existing technologies, although visual monitoring of hoisting has been considered, the monitoring effect is limited and the equipment stability is poor. Summary of the Invention

The elastic element is configured to undergo elastic deformation during the swinging process.
[0010] According to some embodiments of the present invention, the projection assembly is provided with a projection lamp, and the projection lamp is provided with an image rotation mechanism for controlling the rotation of the annular pattern.

Meanwhile, the two left and right vision sensors remain stationary, so as to monitor the hoisting area in real time and avoid the loss of images. This method can effectively monitor the crane hoisting and ensure the safety of the hoisting process.

[0025] Overhead crane hoisting is a cargo lifting technology based on bridge cranes. Bridge cranes are mechanical devices used to lift heavy objects within a fixed span, widely used in workshops, warehouses, or open-air areas. The main beam of a bridge crane spans across a dedicated track at a certain height within the span, allowing it to move longitudinally along the track. A hoisting device is arranged on the main beam, most often a trolley, which can move laterally along the main beam within the span. Resembling a metal bridge, it is called a bridge crane, also commonly known as a "head crane" or "traveling crane." The hoisting device is used to lift and lower heavy objects and is the most important and fundamental mechanism of a bridge crane. Except for a few beam cranes that use electric hoists, bridge cranes generally use a trolley for their hoisting devices. The trolley consists of a frame, traveling mechanism, hoisting and winding mechanism, and electrical equipment. The frame is supported by four wheels, and the traveling mechanism on the frame drives the wheels to move along the trolley track to achieve lifting at different positions across the span. During operation, the main beam can run along the entire longitudinal direction of the factory building, and the trolley can run laterally on the main beam bridge, forming a rectangular working area within the workshop. Goods are lifted and transported within this rectangular working area by the lifting and winding mechanism.
[0026] There are safety risks during overhead crane operations, including the risk of the hoisted object falling and the risk of interference with the hoisting path. In the relevant existing technologies, although visual monitoring of hoisting has been considered, the monitoring effect is limited and the equipment stability is poor.
[0027] In response, this invention provides a crane safety control system that can effectively monitor crane lifting operations and ensure the safety of the lifting process.
[0028] Reference Figures 1 to 7 This embodiment proposes a crane safety control system, including a crane hoisting device, a vision monitoring module, and a control center. The crane hoisting device is equipped with a lifting trolley for lifting goods. The crane hoisting device in this embodiment can adopt existing structural forms as needed. The vision monitoring module is mounted on the lifting trolley. The vision monitoring module includes a projection component and a vision component. The projection component projects a circular pattern downwards, surrounding the lifting area of the lifting trolley. The vision component has vision sensors 300 rotatably mounted on the front, rear, left, and right sides of the projection component. The vision sensors 300 can swing in a direction away from the projection component to detect the presence of an object in the target area. The control center is connected to the lifting trolley and the vision monitoring module. When the lifting trolley moves in the front-rear direction, it controls the vision sensors 300 located on the front and rear sides of the projection component to swing away from the projection component to detect the front-rear path of the lifting area. It also controls the vision sensors 300 located on the left and right sides of the projection component to swing away from the projection component when the lifting trolley moves in the left-right direction to detect the left-right path of the lifting area.
[0029] In application, a circular pattern is projected onto the ground via a projection component. This pattern surrounds the suspended object, clearly marking the safety zone and allowing on-site personnel to clearly identify the avoidance area and avoid the area where the suspended object is located, thus mitigating risks. Simultaneously, the vision component monitors downwards for the presence of any objects in the target area. The target area can be the region corresponding to the projected circular pattern, a larger area, or an area to one side of the circular pattern. The objects to be identified can be moving objects, such as pedestrians or vehicles, or simply the presence of any objects in the target area. Detection helps prevent collisions.
[0030] The crane safety control system of this embodiment, by setting up a projection component and a vision component, can project a clear ring pattern on the ground to delineate the working area during hoisting. Operators can intuitively see the boundary of the hoisting area, thereby judging whether a collision or other potential hazards will occur. The vision component has vision sensors 300 set up in front, behind, to the left, and to the right of the projection component. During hoisting in the forward and backward direction, the front and rear vision sensors 300 can be controlled to swing further away, thereby detecting the hoisting path in advance and judging whether there are any potential hazards. The left and right vision sensors 300 remain stationary, allowing for real-time monitoring of the hoisting area and preventing the loss of image coverage. Therefore, the crane safety control system of this embodiment can effectively monitor crane hoisting and ensure the safety of the hoisting process.
[0031] Combination Figure 2 In some embodiments of the present invention, the visual monitoring module is provided with two linkage components. These two linkage components are respectively connected to the front and rear visual sensors 300 and the left and right visual sensors 300, and are configured to control the synchronous swing adjustment of the front and rear visual sensors 300 and the left and right visual sensors 300, respectively. This embodiment uses two linkage components to control the swing of the front and rear visual sensors 300 and the left and right visual sensors 300, respectively, which simplifies the swing control of the four visual sensors 300 and reduces control costs.
[0032] Reference Figure 2In some embodiments of the present invention, the linkage assembly includes an elastic element (not shown in the figure), a connecting rod 501, and a lifting drive 500, wherein two elastic elements and two connecting rods 501 are provided. Two elastic elements are respectively connected to the upper end of a vision sensor 300, and one end of each connecting rod 501 is fixedly connected to an elastic element, while the other ends extend close to each other and are fixedly connected. The lifting drive 500 is connected to the close ends of the two connecting rods 501. The linkage assembly controls the connecting rods 501 to descend via the lifting drive 500, thereby pulling the vision sensor 300 to swing away from the projection assembly via the elastic element. Simultaneously, the lifting drive 500 controls the connecting rods 501 to rise, thereby pulling the vision sensor 300 to swing closer to the projection assembly via the elastic element. In this embodiment, the elastic element is configured to undergo elastic deformation during the swinging process.
[0033] Understandably, as the visual sensor 300 swings, its upper end will move closer to or further away from the projection component. Since the linkage 501, controlled by the lifting drive 500, can only move up and down, a direct connection between the linkage 501 and the visual sensor 300 would cause a conflict. This embodiment uses an elastic element to connect the visual sensor 300, allowing for effective transmission between the linkage 501 and the visual sensor 300, thus avoiding conflict.
[0034] Specifically, the elastic element can be a spring with a certain strength or a structure like a rubber rod. When the linkage rod 501 rises and falls, the elastic element can effectively transmit the lifting force, causing the vision sensor 300 to swing. At the same time, based on the structural performance of the spring or rubber rod, the two ends of the elastic element can generate relative displacement, thereby avoiding motion conflict between the linkage rod 501 and the vision sensor 300.
[0035] Furthermore, the use of an elastic element to connect the vision sensor 300 can provide shock absorption when the vision sensor 300 swings into position.
[0036] In some embodiments, the lifting drive 500 is configured as a cylinder.
[0037] In some embodiments, the lifting drive 500 is configured as an electrode lead screw mechanism, which uses the rotation of the lead screw to drive the connecting rod 501 to move up and down.
[0038] It is understandable that two lifting drives 500 are set up for each of the two linkage components. In actual settings, the structural settings of the two linkage components can be compatible through reasonable spatial layout, such as distributing the two linkage components vertically in a staggered manner to avoid interference.
[0039] In some embodiments of the present invention, the projection assembly is provided with a projection lamp 200, and the projection lamp 200 has an image rotation mechanism inside for controlling the rotation of the circular pattern. In this embodiment, the control center is also connected to the projection lamp 200 and is used to control the image rotation mechanism to stop rotating when a recognition object appears in the target area.
[0040] During operation, when the hoisting is in normal condition, the projector 200 projects a circular pattern onto the ground and controls the rotation of the circular pattern. When a pedestrian or other obstacle is detected in the target area, it indicates a safety hazard. At this time, the control center sends a signal to stop the image rotation mechanism. Since the operator's line of sight follows the movement of the hoisted object, the problem can be detected in a timely and intuitive manner.
[0041] The projection lamp 200 and the image rotation mechanism in this embodiment can be configured with reference to relevant existing technologies, and are not specifically limited here.
[0042] In some embodiments of the present invention, the visual monitoring module is provided with a housing 100, which serves as a mounting carrier. The housing 100 is detachably connected to the crane trolley via an additional mounting mechanism. Using the structural configuration of this embodiment, the visual monitoring module is detachably mounted on the crane trolley as a single unit via the housing 100, facilitating maintenance and installation, and allowing for upgrades to existing crane structures.
[0043] Reference Figure 3 , Figure 4 In some embodiments of the present invention, the mounting mechanism includes a mounting frame 101 and a limiting assembly. The mounting frame 101 includes a vertically arranged mounting plate 1012 and two horizontally arranged limiting plates 1011. The two limiting plates 1011 are respectively connected to the upper and lower ends of the mounting plate 1012, thereby forming a transverse U-shaped structure, which facilitates transverse clamping onto the crossbeam of the crane trolley frame. Furthermore, the dimensions of the mounting frame 101 are designed according to the dimensions of the crane trolley to which it is to be installed. The limiting assembly includes a screw 1013 and a locking nut 1014 sleeved on the screw 1013. One of the two limiting plates 1011 has a connecting groove 1015 on the side away from the mounting plate 1012. One end of the screw 1013 is hinged to the other. The screw 1013 can swing so that its other end passes through the connecting groove 1015. After being locked by the locking nut 1014, it forms a clamping space with the mounting frame 101 to clamp the frame of the crane trolley.
[0044] In this embodiment, the mounting mechanism uses a mounting bracket 101 to laterally engage the crane trolley, and then uses a limiting assembly to connect two limiting plates 1011 to fix the mounting bracket 101 in place. This structural design is simple to install and compatible with various types of crane installations.
[0045] Reference Figure 5 Furthermore, in some embodiments, the connecting groove 1015 has an L-shaped structure, specifically including a first groove segment perpendicular to the side of the limiting plate 1011 and a second groove segment perpendicular to the first groove segment. The lower end of the screw 1013 is hinged to the lower limiting plate 1011, and the upper end passes through the first groove segment into the end of the second groove segment and is locked, which can effectively improve the stability of the structure.
[0046] Reference Figure 6 , Figure 7 In some embodiments of the present invention, a transverse guide rail 102 is provided on the side of the mounting bracket 101 opposite to the screw 1013, and a positioning hole 1024 is provided at the upper end of the transverse guide rail 102. The housing 100 is slidably sleeved on the transverse guide rail 102 and can slide out from one or both sides of the transverse guide rail 102. The housing 100 is provided with a positioning component, which is configured to engage with the positioning hole 1024 to limit the sliding of the housing 100 relative to the transverse guide rail 102.
[0047] It should be noted that, since the lifting trolley is installed on top of the overhead crane, the height space is limited. In this embodiment, by setting a transverse guide rail 102, the housing 100 can be slidably installed onto the transverse guide rail 102 in the horizontal direction, which improves the convenience of disassembly and assembly and facilitates the upgrading and transformation of existing equipment. At the same time, it can also ensure the installation stability of the overall structure.
[0048] Combination Figure 7 Furthermore, in some embodiments, a plurality of sliders 1021 are provided on the side of the housing 100 near the mounting plate 1012. The sliders 1021 are matched with the transverse guide rail 102 and can be slidably fitted onto the transverse guide rail 102. The positioning assembly includes a positioning pin 1022 and a return spring 1023. The positioning pin 1022 is vertically inserted into the slider 1021, and the return spring 1023 applies a downward force to the positioning pin 1022. The upper end of the positioning pin 1022 extends to the upper end of the slider 1021. During disassembly, the positioning pin 1022 can be pulled upwards from its top to exit the positioning hole 1024, and then the housing 100 can be pushed laterally until the slider 1021 separates from the transverse guide rail 102. During installation, the slider 1021 is simply fitted onto the transverse guide rail 102 and pushed into place, allowing the positioning pin 1022 to automatically insert into the positioning hole 1024 for positioning.
[0049] Using the structural arrangement of this embodiment, the mounting bracket 101 can be installed onto the crane trolley first, and then the housing 100 can be installed onto the mounting bracket 101, improving the convenience of assembly and disassembly. The vision sensor 300 in this application can be a CCD or other optical products with the required magnification as needed.
[0050] In some embodiments of the present invention, the control center is housed within the enclosure 100 and installed as a single unit with the enclosure 100. Only the corresponding wiring harnesses need to be connected.
[0051] In some embodiments of the present invention, the visual monitoring module further includes an audible and visual alarm component, and the control center is connected to the audible and visual alarm component to control the audible and visual alarm component to perform an audible and visual alarm when an object to be identified is present in the target area.
[0052] Reference Figure 2 In some embodiments of the present invention, the visual monitoring module further includes a heat dissipation component 400, and a control center is connected to the heat dissipation component 400 for adjusting the heat dissipation power of the heat dissipation component 400. Specifically, the heat dissipation component 400 may be equipped with multiple cooling fans, and the control center adjusts the heat dissipation power of the heat dissipation component 400 by activating the number of cooling fans. Alternatively, it may be equipped with cooling fans having multiple speed levels, and the heat dissipation power can be adjusted by adjusting the speed levels.
[0053] It is understandable that this embodiment integrates a projection lamp 200 and four vision sensors 300 within the housing 100, resulting in relatively concentrated heat generation. By setting up a heat dissipation component 400, heat dissipation can be effectively achieved, ensuring the stable operation of the visual monitoring mechanism.
[0054] Reference Figure 1 The present invention also proposes a driving safety control method, applied to the above-mentioned driving safety control system, comprising: firstly acquiring the hoisting direction of the crane trolley; if the crane trolley hoists along the front-to-back direction, keeping the left and right vision sensors 300 in their original positions to monitor the hoisting area of the crane trolley in real time, and controlling the front and rear vision sensors 300 to swing in the front-to-back direction respectively to detect the front-to-back direction of the hoisting area to determine whether the hoisting path is safe; if the crane trolley hoists along the left-to-right direction, keeping the front and rear vision sensors 300 in their original positions to monitor the hoisting area of the crane trolley in real time, and controlling the left and right vision sensors 300 to swing in the left-to-right direction respectively to detect the left-to-right direction of the hoisting area to determine whether the hoisting path is safe.
[0055] It is understood that the crane safety control method of this embodiment can control the two front and rear vision sensors 300 to swing to a distance when hoisting in the front and rear direction, so as to detect the hoisting path in advance and determine whether there are any hidden dangers. Meanwhile, the two left and right vision sensors 300 remain stationary and can monitor the hoisting area in real time to avoid the loss of images. This can effectively monitor the crane hoisting and ensure the safety of the hoisting process.
[0056] Furthermore, the driving safety control method also includes periodically controlling the swing of the vision sensor 300 corresponding to the hoisting direction during the hoisting process to detect any potential hazards on the hoisting path.
[0057] The embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited to the above embodiments, and various changes can be made within the scope of knowledge possessed by those skilled in the art without departing from the spirit of the present invention. Furthermore, the embodiments of the present invention and the features thereof can be combined with each other unless otherwise specified.
