Description

Technical Field

[0001] This utility model belongs to the field of tire crane technology, specifically a tire crane obstacle detection device for container terminals. Background Technology

[0002] A tire-mounted crane, also known as a tire crane, is a type of rotating crane that uses a tire chassis to move. It is a full-rotation crane with the lifting mechanism mounted on a specially designed chassis consisting of heavy-duty tires and axles. Its superstructure is basically the same as that of a crawler crane. To ensure the stability of the crane body during installation operations, it is equipped with four retractable outriggers.

[0003] A search of Chinese Patent Publication No. CN212845941U reveals a device for detecting the distance to an obstacle. The technical solution includes: an infrared light source, a first lens positioned in front of the infrared light source, a light receiver, a second lens positioned in front of the light receiver, and a reflector positioned between the second lens and the light receiver; the reflector is positioned on the side of the second lens furthest from the first lens and connected to the light-emitting surface of the second lens. This invention, by connecting a reflector to the light-emitting surface of the second lens, ensures that all infrared light passing through the second lens and incident on the reflector can reach the light receiver, enabling the sensor to accurately determine the distance to the obstacle. However, in the above scheme, the tire crane has a large range of movement and uses light reflection to detect obstacles. However, the working environment of the tire crane is not convenient for using this technology. It is not easy to provide a platform for installing the reflector, which results in a limited detection range in the plane. It cannot fully detect obstacles in the direction of movement. In addition, the tire crane is relatively high, so this technology is not convenient for detecting obstacles at high altitudes. Utility Model Content

[0004] To address the problem that existing detection devices have limited detection range in a plane and are unsuitable for use at higher locations due to the lack of a reflector in the installation environment, this invention provides a device for detecting obstacles on a plane that can expand the detection range without relying on a reflector and can be used at higher locations, such as container terminal rubber-tired gantry cranes.

[0005] This utility model is achieved through the following technical solution: A container terminal rubber-tired gantry crane obstacle detection device includes a movable component, a steering component connected to the movable component that can move vertically along the movable component, and an obstacle detection component connected to the steering component that can rotate horizontally around the steering component. The steering assembly includes a steering rod, a connecting rod, an arc-shaped plate, and a connecting block. The moving assembly is connected to the arc-shaped plate and a fixed plate. The steering rod is rotatably mounted on the fixed plate. The steering rod is also connected to the connecting rod. The connecting rod is hinged to the connecting block, which can contact the outer wall of the arc-shaped plate. The connecting block is provided with an angle adjustment component that contacts the arc-shaped plate. The connecting block is connected to the obstacle detection assembly.

[0006] The moving component allows for vertical adjustment of the steering component. The steering component, via a pivot, enables the connecting block of the obstacle detection component to rotate horizontally. Simultaneously, in conjunction with the angle adjustment component and the curved surface of the arc plate, the angle increases when moving to the side of the arc plate. When in the centered state, it forms a return-to-center structure, which helps to achieve a larger range of rotation without relying on reflectors, thereby obtaining a larger detection range and enhancing the safety of the tire crane in complex environments.

[0007] A further improvement of this invention is that the aforementioned angle adjusting components are symmetrically arranged on both sides of the connecting rod, and the angle adjusting components are spring plunger structures. The spring plunger structure allows for compression and rebound changes, and because the angle adjusting components are symmetrical on both sides of the connecting rod, when the connecting block rotates to one side of the arc plate, the spring plunger closer to the edge of the arc plate experiences a larger compression space. Therefore, under the action of compression and elastic reset, the spring plunger forces the connecting block to form a larger rotation angle towards the side. When in the middle position of the arc plate, the spring plungers on both sides form a symmetrical balance, achieving a centered and aligned state for the connecting block.

[0008] A further improvement of this invention is that the connecting block has a steering groove on the side near the steering rod, and the radius of curvature of the steering groove is greater than that of the outer side of the arc plate. This structural design helps to ensure that the spring plungers on both sides are always in contact with the arc plate, so as to avoid the connecting block from rotating too much and getting stuck, which would prevent it from rotating flexibly around the connecting rod.

[0009] A further improvement of this invention is that a guide groove is provided on the outer surface of the aforementioned arc-shaped plate, and the angle adjusting member extends into the guide groove. The guide groove provides a limiting path for the movement of the spring plunger, which helps to improve the stability of the rotation trajectory.

[0010] A further improvement of this invention is that an arc-shaped groove runs through the arc-shaped plate, and a connecting rod runs through the arc-shaped groove. In this case, the arc-shaped plate not only helps increase the turning angle range of the connecting block, but also provides support for the connecting rod through the arc-shaped groove.

[0011] A further improvement of this invention is that the connecting rod is provided with an arc-shaped block, which abuts against the inner arc surface of the arc plate. The arc-shaped block increases the contact area with the arc plate, thereby improving support stability.

[0012] A further improvement of this invention is that a fixing nut is threaded onto the connecting rod to bring the arc-shaped block into contact with the arc-shaped plate. Adjusting the fixing nut on the connecting rod limits the maximum distance the arc-shaped block can retract on the connecting rod, ensuring the effective support between the arc-shaped block and the arc-shaped plate.

[0013] A further improvement of this utility model is that the aforementioned movable component includes a mounting plate, a lead screw, a threaded block, and a support plate. The mounting plate is provided with a movable groove and a sliding groove. The movable groove is vertically arranged in the middle of the mounting plate, and the sliding grooves are symmetrically arranged on both sides of the movable groove. The lead screw is rotatably disposed within the movable groove, and the lead screw is connected to the support block through the threaded block. The support plate moves along the sliding groove via a slider. The support plate, through the cooperation of the lead screw, threaded block, slider, movable groove, and sliding groove, forms a ball screw pair mechanism, thereby completing the height adjustment of the support plate.

[0014] A further improvement of this utility model is that the aforementioned fixing plate and arc-shaped plate are connected to the support plate.

[0015] As can be seen from the above technical solutions, the beneficial effects of this utility model are: the moving component can realize the adjustment of the steering component in the vertical direction, and the steering component realizes the horizontal rotation of the connecting block of the obstacle detection component through the rotating shaft. At the same time, in cooperation with the angle adjustment component and the curved surface of the arc plate, the angle increases when moving to the side of the arc plate. When in the center state, it can form a return-to-center change structure, which helps to achieve a larger range of rotation without relying on the reflector, so as to obtain a larger detection range and enhance the safety of the tire crane in complex environments.

[0023] To make the objectives, features, and advantages of this utility model more apparent and understandable, the technical solutions of this utility model will be clearly and completely described below with reference to the accompanying drawings of the specific embodiments. Obviously, the embodiments described below are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this patent, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this patent.

[0024] like Figures 1-5 As shown, this utility model discloses a container terminal tire crane obstacle detection device, including a moving component 40, a steering component 20 that can move vertically along the moving component 40, and an obstacle detection component 10 that can rotate horizontally around the steering component 20.

[0025] The movable component 40 includes a mounting plate 43, a lead screw 47, a threaded block 42, and a support plate 34. The mounting plate 43 has a movable groove 45 and a sliding groove 44. The movable groove 45 is vertically arranged in the middle of the mounting plate 43, and the sliding grooves 44 are symmetrically arranged on both sides of the movable groove 45. The lead screw 47 is rotatably disposed in the movable groove 45 and is connected to the support block through the threaded block 42. The support plate 34 moves along the sliding groove 44 through a slider 41. The support plate 34 forms a ball screw pair mechanism through the cooperation of the lead screw 47, the threaded block 42, the slider 41, the movable groove 45, and the sliding groove 44, thereby completing the height adjustment of the support plate 34.

[0026] The mounting plate 43 is equipped with a movable motor 46 capable of rotating in both directions. The output shaft of the movable motor 46 is coaxially connected to the lead screw 47. By driving the lead screw 47 to rotate through the movable motor 46, the lead screw 47 pushes the threaded block 42 to move reciprocally along the slide groove 44 via the slider 41, thereby realizing the height adjustment of the steering assembly 20.

[0027] The steering assembly 20 includes a steering rod 30, a connecting rod 25, an arc plate 23, and a connecting block 21. The moving assembly 40 is connected to the arc plate 23 and a fixed plate 29. The steering rod 30 is rotatably mounted on the fixed plate 29. The connecting rod 25 is also connected to the steering rod 30. The connecting rod 25 is hinged to the connecting block 21, which can contact the outer wall of the arc plate 23. The connecting block 21 is provided with an angle adjustment component 28 that contacts the arc plate 23. The connecting block 21 is connected to the obstacle detection assembly 10. The movable component 40 can adjust the steering component 20 in the vertical direction. The steering component 20 rotates the connecting block 21 of the obstacle detection component 10 in the horizontal direction through the rotating shaft. At the same time, it cooperates with the curved surface of the angle adjustment component 28 and the arc plate 23 to increase the angle when moving to the side of the arc plate 23. When in the center state, it can form a return-to-center structure, which helps to achieve a larger range of rotation without relying on the reflector, so as to obtain a larger detection range and enhance the safety of the tire crane in complex environments.

[0028] The fixed plate 29 and the arc plate 23 are connected to the support plate 34. There are two fixed plates 29, which are installed at the higher end and the lower end of the support plate 34, respectively. The arc plate 23 is disposed between the two fixed plates 29. Preferably, two arc plates can be disposed along the axial direction of the steering rod 30.

[0029] The steering rod 30 passes through two fixed plates 29. A reversible steering motor 33 is mounted on the top fixed plate 29. The output shaft of the steering motor 33 is coaxially connected to the steering rod 30 to drive the steering rod 30 to swing circumferentially. A thrust ring 32 is provided below the bottom fixed plate 29. The thrust ring 32 passes through the steering rod 30 and cooperates with the steering motor 33 to prevent the steering rod 30 from moving axially on the fixed plate 29.

[0030] The angle adjustment element 28 is symmetrically arranged on both sides of the connecting rod 25, and the angle adjustment element 28 is a spring plunger structure. The angle adjustment element 28 of the spring plunger structure can realize the change of compression and rebound. Since the angle adjustment element 28 is symmetrical on both sides of the connecting rod 25, when the connecting block 21 rotates to one side of the arc plate 23, the spring plunger closer to the side of the arc plate 23 will be subjected to a larger compression space. Therefore, under the action of compression and elastic reset, the spring plunger forces the connecting block 21 to form a larger rotation angle to the side. When it is in the middle position of the arc plate 23, the spring plungers on both sides form a symmetrical balance, achieving the centered and upright state of the connecting block 21.

[0031] In order to ensure that the spring plunger can form a good moving guide with the arc plate 23 and avoid jamming, the axis of the spring plunger is pointing to the axis of the steering rod 30 in the horizontal plane, so that the spring plunger can form a relatively stable included angle with the outer side of the arc plate 23 during the movement.

[0032] The outer surface of the arc-shaped plate 23 is provided with a guide groove 281, and the angle adjusting member 28 extends into the guide groove 281. The guide groove 281 provides a limiting for the movement trajectory of the spring plunger, which helps to improve the stability of the rotation trajectory.

[0033] The connecting block 21 has a steering groove 22 on the side near the steering rod 30, and the radius of the steering groove 22 is greater than the radius of the outer side of the arc plate 23. This structural design helps to ensure that the spring plungers on both sides are always in contact with the arc plate 23, so as to avoid the connecting block 21 from getting stuck due to excessive rotation angle, which would prevent it from rotating flexibly around the connecting rod 25.

[0034] An arc-shaped groove 24 extends through the arc-shaped plate 23, and a connecting rod 25 passes through the arc-shaped groove 24. At this time, the arc-shaped plate 23 not only helps to increase the turning angle range of the connecting block 21, but also supports the connecting rod 25 with the help of the arc-shaped groove 24.

[0035] The upper and lower sides of the arc-shaped groove 24 are provided with guide grooves 281, which can form an arc-shaped plate 23 corresponding to a connecting rod 25. The outer periphery of the connecting rod 25 corresponds to the structure of four spring plungers, and the four spring plungers are distributed in a square on the outer periphery of the connecting rod 25, which helps to improve the adaptability of steering flexibility.

[0036] The connecting rod 25 is equipped with an arc-shaped block 27, which abuts against the inner arc surface of the arc-shaped plate 23. The arc-shaped block 27 increases the contact area with the arc-shaped plate 23, improving support stability. A fixing nut 26 is threaded onto the connecting rod 25 to bring the arc-shaped block 27 into contact with the arc-shaped plate 23. Adjusting the fixing nut 26 on the connecting rod 25 limits the maximum distance the arc-shaped block 27 can retract on the connecting rod 25, ensuring the effective support between the arc-shaped block 27 and the arc-shaped plate 23. The arc-shaped block 27 only partially abuts against the arc-shaped plate 23; the purpose of this contact structure is to increase the effective contact area of ​​the stabilizing connecting rod 25.

[0037] The obstacle detection component 10 includes a mounting shell 11, an ultrasonic module 12, a sound wave transmitter 13, a sound wave receiver 14, a circuit board 15, an oscillator 16, a controller 17, an image processor 18, and an image acquisition device 19. The mounting shell 11 is connected to the side of the connecting block 21 facing away from the moving component 40. The circuit board 15 is installed inside the mounting shell 11, and the ultrasonic module 12, the sound wave transmitter 13, the sound wave receiver 14, the oscillator 16, the controller 17, the image processor 18, and the image acquisition device 19 are installed on the circuit board 15. The controller 17 is electrically connected to the ultrasonic module 12 and the image processor 18. The controller 17 processes and controls the ultrasonic module 12 and the image processor 18. The controller 17 is electrically connected to the tire crane and sends the processing results to the tire crane. The ultrasonic module 12 includes an oscillator 16 that generates ultrasonic waves. The oscillator 16 is electrically connected to a sound wave transmitter 13, which emits the ultrasonic waves. The sound wave transmitter 13 is electrically connected to a sound wave receiver 14. When the sound waves encounter an obstacle, they are reflected. The sound wave receiver 14 receives the reflected sound waves and sends them to the controller 17 for judgment. The image processor 18 is electrically connected to an image acquisition unit 19. The image acquisition unit 19 sends the acquired images to the image processor 18, which analyzes the images and sends them to the controller 17 for judgment.

[0038] During use, the oscillator 16 oscillates, emitting ultrasonic waves of a specific frequency. The ultrasonic wave transmitter 13 of the ultrasonic module 12 emits the ultrasonic waves. When the sound waves collide with an object, they bounce back and are received by the sound wave receiver 14. The reflection information is sent to the controller 17, which analyzes the sound waves. The image acquisition unit 19 sends the acquired images to the image processor 18, which analyzes the images to determine the material and position of the object. The controller 17 combines the sound wave reflection information and the image processing information. If it determines that there is an obstacle, it sends a signal to the tire crane operator. It can process obstacle information, accurately judge the situation of the obstacle, and determine whether it is possible to pass. It is highly practical.

[0039] The electronic components and electrical connection methods within the obstacle detection component 10 are all mature and known technologies in the prior art. This case simply applies the obstacle detection component 10 with detection function to the steering component 20, which can expand the rotation angle in the horizontal plane. At the same time, in order to ensure the convenience of use in the outdoor environment, a transparent protective plate can be encapsulated on the mounting shell 11 to protect the electronic components inside the mounting shell 11 without affecting the sound wave transmission and reception and image acquisition.

[0040] The obstacle detection device for a container terminal rubber-tired gantry crane described in this utility model has a movable component that allows for vertical adjustment of the steering component. The steering component, via a rotating shaft, enables the connecting block of the obstacle detection component to rotate horizontally. Simultaneously, by cooperating with the angle adjustment component and the curved surface of the arc plate, the angle increases when moving to the side of the arc plate. When in the centered state, it can form a return-to-center structure, which helps to achieve a larger range of rotation without relying on a reflector, thereby obtaining a larger detection range and enhancing the safety of the rubber-tired gantry crane in complex environments.
