Description

Technical Field

[0001] This application relates to the field of wind-powered self-locking technology, and in particular to a wind-powered self-locking anti-climb device. Background Technology

[0002] Large rail-mounted port machinery, such as container cranes and gantry cranes, are often affected by extreme weather such as typhoons, hurricanes, and tornadoes when operating outdoors. Although these machines are designed to withstand severe wind loads, they can still be blown over by strong winds. The main reason is that the anti-overturning stability of the equipment is calculated based on the equipment's static state. If the equipment's anti-slip ability is insufficient under extreme wind loads, it will accelerate along the track after being propelled by strong winds, colliding with nearby equipment or the limit baffles set at the end of the track. At this time, the overturning moment generated by the inertial force is much greater than the anti-overturning moment generated by the equipment's own weight, causing the equipment to overturn. Therefore, it is necessary to install windproof and anti-slip devices.

[0003] Rail clamps are common wind-resistant and anti-slip devices. Although rail clamps have a certain wind-resistant and anti-slip capability, their design is usually based on the geometry of the track under ideal conditions. However, in actual operation, uneven tracks caused by port and dock settlement or skewed trolley wheels are common. Therefore, once the track deforms or the height changes beyond a certain range, the effective clamping area of ​​the rail clamp decreases, reducing the clamping force and thus leading to a decline in wind-resistant and anti-slip performance. This increases the risk of equipment displacement or even overturning under strong wind conditions. To solve the above problems, a wind-powered self-locking anti-climb device is proposed.

[0004] The information disclosed in this background section is only intended to enhance the understanding of the background technology of this application, and therefore may include prior art that is not known to those skilled in the art. Utility Model Content

[0005] To address the aforementioned issues, this application provides a wind-powered self-locking anti-climb device.

[0006] The wind-powered self-locking anti-climb device provided in this application adopts the following technical solution:

[0007] A wind-powered self-locking anti-climb device includes a movable frame that slides on a track. A pulley is rotatably mounted inside the movable frame, and the pulley is in contact with the track surface. A support frame is located at the top of the movable frame. A swing arm and a swing assembly for driving the swing arm to swing are located within the support frame. Hydraulic cylinders are hinged to both ends of the swing arm. A connecting frame is located at the telescopic end of each hydraulic cylinder. A locking wheel rotatably mounts within the connecting frame. An adjustment assembly for driving the locking wheel to rotate is located at the top of the hydraulic cylinder. The locking wheel remains in contact with the track surface at all times.

[0008] Preferably, the swing assembly includes a first gear, a second gear, a mounting frame, and a first motor. The support frame is hollow. Both the first gear and the second gear rotate on the inner wall of the support frame. The first gear is fixed to the middle section of the swing rod. The mounting frame is fixed to one side of the inner wall of the support frame. The first motor is fixed to one side of the mounting frame. The rotor end of the first motor is fixed to the second gear. The first gear and the second gear mesh.

[0009] Preferably, the adjustment assembly includes a hinge cylinder, gear three, gear four, and motor two. The hinge cylinder is hinged to both ends of the rocker arm. The hydraulic cylinder rotates inside the hinge cylinder. Gear three is fixed to the top of the hydraulic cylinder. Gear four rotates on the top of the hinge cylinder. Gear three and gear four mesh. Motor two is fixed on the hinge cylinder. The rotor end of motor two is fixed to gear four.

[0010] Preferably, guide grooves are provided on both sides of the inner wall of the support frame, and a slider is provided on the side of the hinge cylinder near the guide groove, and the slider slides in the guide groove.

[0011] Preferably, there is a gap between the connecting frame and the movable frame on the side that is close to each other.

[0012] Preferably, the support frame has a fixing frame on top, and the fixing frame has multiple mounting holes.

[0013] Preferably, the top of the hinged cylinder has a mounting slot for the second power supply motor.

[0014] In summary, this application includes the following beneficial technical effects:

[0015] By installing a swing arm within the support frame, with hydraulic cylinders hinged at both ends, and cooperating with the locking wheel at the telescopic end of the hydraulic cylinder and the adjusting component that drives the locking wheel to rotate, the combined action of the swing component and the adjusting component ensures that the locking wheel always remains in close contact with the track. Compared with related technologies, the cooperation between the locking wheel and the adjusting and swing components allows for flexible adjustment of the contact state with the track, ensuring effective clamping area and clamping force under different track geometries. Even when the track deforms or the height changes beyond a certain range, it can still maintain efficient windproof and anti-slip performance, effectively reducing the risk of equipment displacement or even overturning under strong wind conditions. At the same time, when the equipment is initially displaced by the wind, it can quickly respond and increase friction, thereby curbing further movement of the equipment and avoiding collisions with nearby equipment or the limit baffle at the end of the track. This further reduces the overturning moment caused by inertial forces and enhances the overall anti-overturning stability of the equipment. Attached Figure Description

Detailed Implementation

[0021] The following is in conjunction with the appendix Figure 1-4 This application will be described in further detail.

[0022] This application discloses a wind-powered self-locking anti-climb device. (Refer to...) Figure 1-4 A wind-powered self-locking anti-climb device includes a movable frame 1 that slides on a track 101. A pulley 2 is rotatably mounted inside the movable frame 1, and the pulley 2 is in contact with the surface of the track 101. A support frame 3 is mounted on the top of the movable frame 1, and a fixed frame 17 is mounted on the top of the support frame 3. Multiple mounting holes are provided on the fixed frame 17 to fix the self-locking anti-climb device to the equipment. A swing rod 4 and a swing assembly for driving the swing rod 4 to swing are provided inside the support frame 3. The swing assembly includes a first gear 5, a second gear 6, a mounting frame 7, and a first motor 8. The support frame 3 is hollow. Both the first gear 5 and the second gear 6 rotate on the inner wall of the support frame 3. The first gear 5 is fixed to the middle section of the swing rod 4. The mounting frame 7 is fixed to one side of the inner wall of the support frame 3, and the first motor 8 is fixed to one side of the mounting frame 7. The rotor end of motor 8 is fixed to gear 6. Gear 5 meshes with gear 6. When the height of track 101 is uneven due to the settlement of the dock, motor 8 is started to rotate forward or reverse, causing gear 6 to rotate and drive gear 5 and its swing arm 4 to swing. Hydraulic cylinders 9 are hinged at both ends of the swing arm 4. The extension end of the hydraulic cylinder 9 is provided with a connecting frame 12. A locking wheel 13 rotates inside the connecting frame 12. As the swing arm 4 swings, one hydraulic cylinder 9 drives its locking wheel 13 to fit with the lower part of track 101. The other hydraulic cylinder 9 is started to push its other locking wheel 13 to keep it in contact with track 101, so that the locking wheel 13 is always in contact with the surface of track 101, maintaining the balance and stability of the equipment.

[0023] It should be noted that when the equipment is in normal use, the locking wheel 13 can play the same role as the pulley 2, assisting the equipment to move smoothly on the track 101. When encountering strong winds, when the equipment is pushed by the wind and causes initial displacement, the hydraulic cylinder 9 is activated to push the locking wheel 13 against the track 101, quickly responding to lock and stopping the equipment from moving further, thus avoiding collisions with nearby equipment or the limit baffle at the end of the track.

[0024] Reference Figure 2 , 3 The top of the hydraulic cylinder 9 is equipped with an adjustment assembly for driving the locking wheel 13 to rotate. The adjustment assembly includes a hinge cylinder 14, gear three 15, gear four 16, and motor two 18. The hinge cylinder 14 is hinged to both ends of the rocker arm 4. The hydraulic cylinder 9 rotates inside the hinge cylinder 14. Gear three 15 is fixed to the top of the hydraulic cylinder 9, and gear four 16 rotates on the top of the hinge cylinder 14. Gear three 15 and gear four 16 mesh. Motor two 18 is fixed to the hinge cylinder 14, and the rotor end of motor two 18 is fixed to gear four 16. A motor two 18 is installed on the top of the hinge cylinder 14. The mounting slot 19 ensures the stable installation of motor 18. When the track bends or deforms, motor 18 is started to rotate gear 16, which in turn drives gear 15 and its hydraulic cylinder 9 to rotate. This allows for adjustment of the angle of the locking wheel 13 at its telescopic end, thus flexibly adjusting the contact state between the locking wheel 13 and the track 101. This ensures that effective clamping area and clamping force are maintained under different track 101 geometries. Even if the track deforms or the height changes beyond a certain range, it can still maintain efficient windproof and anti-slip performance.

[0025] Reference Figure 1 The inner walls of the support frame 3 are provided with guide grooves 11 on both sides. The hinge cylinder 14 is provided with a slider 10 on the side near the guide groove 11. The slider 10 slides in the guide groove 11. The sliding cooperation between the guide groove 11 and the slider 10 provides guidance for the swing of the rocker arm 4, ensuring the vertical lifting of the hydraulic cylinder 9, and thus ensuring the effective locking of the locking wheel 13.

[0026] Reference Figure 4 There is a gap between the connecting frame 12 and the moving frame 1 on the side that are close to each other, so that the locking wheel 13 can be adjusted smoothly without being interfered with by the moving frame 1.
