Description
Technical Field
[0001] This utility model belongs to the technical field of safety facilities for lifting equipment, and specifically relates to a vehicle visual monitoring module. 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 an overhead 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 an overhead crane, also commonly known as a "bridge crane" or "traveling crane." The hoisting device is used to lift and lower heavy objects and is the most important and fundamental mechanism of an overhead crane. Except for a few beam cranes that use electric hoists, the hoisting device of an overhead crane generally uses a trolley. The trolley consists of a frame, a traveling mechanism, a 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 along the width of 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 associated with overhead crane lifting operations, including: I. Risk of falling objects, such as... Rope slippage accident: The heavy object falls from the lifting rope, commonly due to improper binding methods or misalignment of the lifting center. Unhooking accident: The hook or lifting gear unexpectedly comes off, possibly due to a malfunction of the hook guard or improper operation; Rope breakage accident: A steel wire rope breaks due to overloading, wear, or insufficient maintenance, causing the heavy object to fall. II. Equipment malfunction, such as... Equipment aging: Overhead cranes that have been used without maintenance for a long time may experience problems such as wire rope wear and aging electrical components. Control system malfunctions, such as a failed hook safety device or a malfunctioning limit switch, can lead to an uncontrolled fall. Third, human error, such as... Violations of operating procedures: such as improperly securing materials, failing to promptly avoid suspended loads, and not wearing safety equipment; Insufficient safety awareness: Operators are unfamiliar with safe operating procedures, or on-site management is inadequate; IV. Deficiencies in on-site management, such as: Insufficient warning signs: The lack of clearly marked warning areas or safety barriers leads to people mistakenly entering dangerous areas. The working environment is chaotic: the site is narrow or the materials are not stacked properly, which obstructs the hoisting passage.
[0004] Therefore, it is necessary to strengthen the management of safety in overhead crane operations. While some newer equipment has upgraded with vision-based safety modules, their complex structures make them unsuitable for upgrading existing equipment. Utility Model Content

[0026] 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 an overhead 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.

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.

[0027] There are safety risks associated with overhead crane lifting operations, including: I. Risk of falling objects, such as...

Deficiencies in on-site management, such as: Insufficient warning signs: The lack of clearly marked warning areas or safety barriers leads to people mistakenly entering dangerous areas. The working environment is chaotic: the site is narrow or the materials are not stacked properly, which obstructs the hoisting passage.
[0028] Therefore, it is necessary to strengthen the management of safety in overhead crane operations. While some newer equipment has upgraded with vision-based safety modules, their complex structures make them unsuitable for upgrading existing equipment.
[0029] This utility model provides a vehicle visual monitoring module, which facilitates the upgrading and transformation of existing equipment and solves the shortcomings of traditional structures.
[0030] Reference Figures 1 to 6 This embodiment of a vehicle vision monitoring module includes a housing 100, a mounting mechanism, a projection component, and a vision component. The mounting mechanism is located on one side of the housing 100 in the circumferential direction. The mounting mechanism defines a clamping space suitable for mounting the frame of the crane trolley, thereby connecting the housing 100 to the crane trolley frame and fixing the housing 100 to the crane trolley frame. Both the projection component and the vision component are located inside the housing 100. The projection component projects a circular pattern downwards, and the vision component detects the presence of an object in a target area downwards. Since the ground lies beneath the crane trolley, the projection component projects a circular pattern onto the ground.
[0031] 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.
[0032] The vehicle vision monitoring module in this embodiment can be installed on the frame of the crane trolley by setting a projection component and a vision component inside the housing 100 and then setting an installation mechanism. This allows it to be installed on new equipment or upgraded on existing equipment.
[0033] Furthermore, the vehicle vision monitoring module in this embodiment integrates projection and vision to achieve online monitoring of safe operations, and the addition mechanism enables rapid assembly, which facilitates both upgrading and modifying existing equipment and assembling and upgrading new equipment, effectively solving the shortcomings of traditional structures.
[0034] Reference Figures 1 to 5 In some embodiments of this utility model, the mounting mechanism includes a mounting frame 101 and a limiting component. Specifically, 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 horizontal U-shaped frame. The upper limiting plate 1011 has a connecting groove 1015 on the side away from the mounting plate 1012. The limiting component includes a screw 1013 and a locking nut 1014 sleeved on the screw 1013. The lower end of the screw 1013 is hinged to the lower limiting plate 1011. The screw 1013 can swing so that its upper end enters the connecting groove 1015 and is locked by the locking nut 1014, thereby forming a clamping space with the mounting frame 101.
[0035] During installation, simply slide the mounting bracket 101 horizontally onto the frame from one side, and then install the screw 1013 from the other side to clamp and secure the frame.
[0036] It is understood that the distance between the limiting plates 1011 in this embodiment matches the frame to ensure complete fixation. Simultaneously, the lateral distance between the screw 1013 and the mounting plate 1012 also matches the frame to achieve horizontal clamping and limiting. Furthermore, due to the tightening of the locking nut 1014, the mounting bracket 101 is completely fixed to the frame and will not wobble along the length of the frame.
[0037] The structure adopted in this embodiment is simple, easy to assemble and disassemble, and highly stable, ensuring the stability of the housing 100 during installation.
[0038] Reference Figure 4 In some embodiments of this utility model, the connecting groove 1015 has an L-shaped structure. Specifically, the connecting groove 1015 has a first groove segment perpendicular to the side of the limiting plate 1011 and a second groove segment perpendicularly connected to the first groove segment. During installation, the upper end of the screw 1013 enters the first groove segment from the outside, then enters the second groove segment, and is then locked. This effectively prevents the screw 1013 from coming out of the connecting groove 1015.
[0039] Understandably, one or more screws 1013 can be provided as needed.
[0040] In some embodiments of this utility model, a transverse guide rail 102 is provided on the side of the mounting bracket 101 opposite to the screw 1013, and a positioning hole 1026 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 1026 to limit the sliding of the housing 100 relative to the transverse guide rail 102.
[0041] With the structural configuration of this embodiment, the housing 100 and the mounting frame 101 are separable. The mounting frame 101 can be installed on the frame of the crane trolley first, and then the housing 100 can be installed on the mounting frame 101, which helps to reduce the difficulty of disassembly and assembly and improve the efficiency of disassembly and assembly.
[0042] Specifically, the housing 100 is equipped with a slider 1021, which is slidably sleeved on the transverse guide rail 102. The positioning component includes a positioning part 1022 and an elastic part. The positioning part 1022 is vertically slidably mounted on the slider 1021 and matches the positioning hole 1026 so that it can be inserted into the positioning hole 1026 when aligned. The elastic part is disposed between the slider 1021 and the positioning part 1022 to apply a downward force to the positioning part 1022. It can be understood that when the housing 100 in this embodiment is installed on the mounting bracket 101, the slider 1021 is sleeved on the transverse guide rail 102 and slides along the length of the transverse guide rail 102. When it slides into place, the positioning part 1022 inserts into the positioning hole 1026 on the transverse guide rail 102, thus fixing the housing 100. To disassemble, simply pull the positioning part 1022 out of the positioning hole 1026.
[0043] In some embodiments of this utility model, the housing 100 is provided with multiple sliders 1021, each slider 1021 being equipped with a positioning component to improve the installation stability of the housing 100. The positioning component also includes a linkage unit, which connects all the positioning parts 1022 to simultaneously pull all the positioning parts 1022 out of the positioning holes 1026. This embodiment improves the installation stability of the housing 100 by providing multiple sliders 1021, and simultaneously controls all the positioning parts 1022 to exit the positioning holes 1026 using the linkage unit, facilitating disassembly and improving assembly / disassembly efficiency.
[0044] Reference Figures 1 to 5 Specifically, the mounting bracket 101 has two transverse guide rails 102 on the side opposite to the screw 1013. The two transverse guide rails 102 are spaced apart vertically and parallel to each other. Four sliders 1021 are fixed to the side wall of the housing 100 by welding or other means. The four sliders 1021 are arranged in pairs, with the upper two sliders 1021 slidingly fitted onto the upper transverse guide rails 102, and the lower two sliders 1021 slidingly fitted onto the lower transverse guide rails 102. Each slider 1021 has a vertically positioned positioning part 1022 at its upper end. A spring 1025 connects the positioning part 1022 to the slider 1021, limiting the upward movement of the positioning part 1022. The positioning part 1022 has a pin structure, and its lower end is inserted into a positioning hole 1026. The linkage includes two first links 1023 and one second link 1024. The two ends of the two first links 1023 are respectively connected to two positioning parts 1022 in the same row, and the second link 1024 is vertically connected between the two first links 1023. By simply pulling the second link 1024 or the upper first link 1023 upward, the four positioning parts 1022 can be driven out of their respective matching positioning holes 1026, allowing the slider 1021 to slide relative to the transverse guide rail 102, so that the housing 100 can be removed.
[0045] Reference Figure 1 In some embodiments of this utility model, a projection lamp 200 is disposed at the center of the housing 100 in the projection assembly. A vision sensor 300 is disposed at the front, rear, left, and right of the projection lamp 200 in the vision assembly, with the axis of the vision sensor 300 forming an acute angle with the axis of the projection lamp 200. By employing the structural configuration of this embodiment and setting four vision sensors 300, the detection range can be effectively expanded. When the crane trolley moves forward, backward, left, and right, the direction of travel can be detected in a timely manner to determine whether there are obstacles or personnel in the travel area, thereby improving safety.
[0046] Meanwhile, the acute angle between the axis of the vision sensor 300 and the axis of the projection lamp 200 helps to reduce the impact of the light from the projection lamp 200 on the detection of the vision sensor 300. The four vision sensors 300 can work together to assist in determining the projection range of the projection lamp 200, thereby improving detection accuracy and reliability.
[0047] It should be noted that the projection range of the projector lamp 200 needs to cover the suspended object. Therefore, although the axis of the vision sensor 300 forms an acute angle with the axis of the projector lamp 200, the detection range of the vision sensor 300 can still cover the projection area of the projector lamp 200 to ensure that the area where the suspended object is located is detected.
[0048] In some embodiments of this utility model, the visual sensor 300 is oscillating to increase the axial angle with the projection lamp 200, and the two opposing visual sensors 300 are oscillating synchronously.
[0049] The structural configuration of this embodiment allows for the outward swinging of two opposing vision sensors 300, thereby increasing the detection range. In practical applications, when the crane trolley moves forward, the two vision sensors 300 on the front and rear sides swing forward and backward respectively, performing a rapid scan in the forward and backward directions to determine whether there are obstacles or personnel on the path. Meanwhile, the two vision sensors 300 on the left and right sides remain stationary, ensuring real-time monitoring of the area where the load is located and preventing the loss of image data that could lead to potential hazards. Conversely, when the crane trolley moves left and right, the two left and right vision sensors 300 swing rapidly to the left and right respectively for detection, while the two front and rear vision sensors 300 remain stationary, providing real-time monitoring of the area where the load is located.
[0050] Combination Figure 1 Specifically, a base is located at the center of the housing 100, and a projection lamp 200 is vertically mounted in the middle of the base to project a circular pattern downwards. Four vision sensors 300 are respectively mounted on the base and located at the front, rear, left, and right sides of the projection lamp 200. The vision sensors 300 are rotatably connected to the base at their midpoints in the height direction. A set of transmission components is connected between the upper ends of two vision sensors 300 that are opposite each other front-to-back or left-to-right. The transmission components include a hinge seat and two transmission rods 501. The near ends of the two transmission rods 501 are hinged to the hinge seat, and the far ends of the transmission rods 501 extend to the upper end of the vision sensors 300 and are hinged to the vision sensors 300. A lifting drive 500 for the hinge seat is provided on the base. The lifting drive 500 pulls the vision sensors 300 to swing by controlling the lifting of the hinge seat. The lifting drive 500 can adopt a cylinder or motor telescopic structure. Figure 1 A spring 1025 structure can be installed at the end of the transmission rod 501 near the vision sensor 300 for connection, thereby avoiding interference.
[0051] It is understandable that the front and rear vision sensors 300 and the left and right vision sensors 300 are each controlled by a lifting drive 500.
[0052] Furthermore, the base adopts a heat-conducting structure, while maintaining a gap between the base and the corresponding structure to form an air gap.
[0053] Combination Figure 1 In some embodiments of this utility model, the housing 100 is provided with a heat dissipation assembly 400 for heat dissipation. Specifically, the heat dissipation assembly 400 includes a fan disposed on one side of the housing 100 and an air outlet grille disposed on the other side of the housing 100. Air outlet gaps are also provided at the top and bottom of the housing 100. During operation, the fan blows air into the housing 100, and air is also discharged from the opposite side and the top and bottom sides of the housing 100, achieving efficient heat dissipation. Furthermore, the bottom air outlet of the housing 100 helps reduce dust accumulation on the projection lamp 200 and the vision sensor 300.
[0054] In some embodiments of this utility model, the vehicle vision monitoring module further includes an audible and visual alarm component, which is disposed on the outside of the housing 100. This audible and visual alarm component is used to issue a warning when the vision sensor 300 detects an obstacle or person in the target area, thereby alerting the operator and facilitating timely shutdown. It also prompts personnel in the target area to avoid the obstacle.
[0055] Furthermore, the crane vision monitoring module also includes a controller, housed inside the housing 100, which connects to the projection component, vision component, and audible and visual alarm component for operational control. This controller allows for manual setting of operating modes and can connect to the crane system for coordinated operations. For example, when the crane controls the movement of the hoisting trolley, the vision component can be controlled for rapid detection. The vision sensor 300 in this application can be a CCD or other optical product with the required magnification, depending on the needs.
[0056] In summary, the crane vision monitoring module of this embodiment can be quickly installed on the crane trolley for modification and upgrade. After installation, the module only requires wiring connections, such as power and communication cables, to be put into use. In stand-alone operation, only the power cable needs to be connected. The crane vision monitoring module projects a pattern around the suspended load using the projector 200, providing a clear view of the work area. It detects obstacles, such as personnel, within the projection area using vision components, and issues an alarm when an obstacle is detected. In online operation, the module can be connected to the crane's control system via the communication cable. The application is flexible and versatile, and the structure is simple and reliable.
[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. Within the scope of knowledge possessed by those skilled in the art, various changes can be made 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.
