Description

Technical Field

[0001] This utility model relates to the field of crane technology, and more specifically to a vertical windproof cable device for a rail-mounted crane. Background Technology

[0002] Rail-mounted cranes are essential lifting equipment in ports and docks, widely used for loading, unloading, and handling cargo. With the increasing number of port cranes at docks, higher demands are placed on equipment management and safe operation. Rail-mounted cranes are frequently exposed to strong winds, especially in coastal areas where strong sea breezes or typhoons can cause them to move along the tracks or even overturn, potentially colliding with other equipment and causing damage or accidents. Therefore, windproof devices for cranes and other similar equipment are indispensable.

[0003] Currently, the windproof cable devices for port rail cranes mainly come in the following two forms:

[0004] Manual screw rotation method: This method involves manually rotating the screw to adjust the length of the windproof cable, thereby fixing or releasing the crane. However, the manual screw rotation method has a complex structure and large size, increasing the overall weight of the equipment, making installation and maintenance inconvenient, and the operation is cumbersome, labor-intensive, and has a low degree of automation.

[0005] Electric cable type: Some cranes use electric cable type wind protection devices. Although they can achieve automated operation, the structure of electric cable devices is relatively complex, which increases the failure rate of the equipment.

[0006] Therefore, developing a simple and easy-to-operate vertical windproof cable device for rail-mounted cranes is a problem that urgently needs to be solved by those skilled in the art. Utility Model Content

[0007] In view of this, the present invention provides a simple and easy-to-operate vertical windproof cable device for rail-mounted cranes. To achieve the above objectives, the present invention adopts the following technical solution: A vertical windproof cable device for a rail-mounted crane, comprising: An anchoring assembly, which is fixed to the ground, includes: a base and a connecting plate, the middle part of which is rotatably connected to the base, one end of which has a connecting hole and the other end has a hinge shaft; The bottom of the cable rod is connected to the side of the connecting plate that has a connection hole; A lifting push rod, which is connected to the cable rod body; A pressure rod, the top of which is connected to the telescopic end of the lifting push rod; the lifting push rod drives the pressure rod to move downward and connect with the hinge shaft; A pin-driven electric push rod is connected to the bottom of the cable rod body. The pin-driven electric push rod pushes the pin out, connecting the connecting plate and the cable rod body.

[0008] The beneficial effects of adopting the above technical solution are that, through the combination of anchoring components, cable rods, lifting push rods, pressure rods and pin shaft electric push rods, the fixing and releasing operations of windproof cables can be automatically completed under normal circumstances, which improves the automation level and ease of operation of the windproof cable device, while also simplifying the structure of the device and reducing the overall weight and failure rate of the equipment.

[0009] Preferably, a fixing plate is hinged to the top of the cable rod, and the fixing plate is fixedly connected to the fixing equipment. The design of the fixing plate hinged to the top of the cable rod enables a stable and reliable connection between the cable rod and the fixing equipment, enhancing the fixing effect and stability of the windproof cable device in actual use, ensuring that the crane can be firmly fixed in strong wind environments, and preventing it from moving or overturning along the track.

[0010] Preferably, the cable rod includes an upper screw, an adjusting sleeve, and a lower screw; the upper screw and the lower screw are respectively threaded to the upper and lower ends of the adjusting sleeve. This structure facilitates the adjustment of the length of the cable rod, allowing for flexible adjustment of the length according to the actual usage scenario and specific equipment requirements. This improves the applicability and versatility of the windproof cable device, enabling it to better adapt to the fixing needs of cranes at different heights and positions.

[0011] Preferably, the top of the upper screw and the bottom of the lower screw are both provided with fork-shaped grooves, and the fixing plate and connecting plate are respectively inserted into the fork-shaped grooves of the upper screw and the lower screw, and are hinged by the screws. This design further optimizes the connection method between the cable rod and the fixing plate and connecting plate, making the connection more stable and reliable, while also facilitating installation and disassembly, and improving the assembly and maintenance efficiency of the device.

[0012] Preferably, the bottom of the lifting push rod is connected to a lifting guide plate, and a guide block is provided on the pressure rod. A guide groove is formed on the surface of the lifting guide plate, and the guide block is slidably connected within the guide groove. This structure provides excellent guidance for the up-and-down movement of the pressure rod, ensuring accurate contact between the pressure rod and the hinge shaft, and driving the connecting plate to rotate. This improves the device's operational accuracy and reliability, and avoids connection failures or equipment damage caused by inaccurate pressure rod movement.

[0013] Preferably, the surface of the pressure rod is further provided with an auxiliary guide block, and the surface of the lifting guide plate is provided with an auxiliary guide groove, and the auxiliary guide block is slidably connected in the auxiliary guide groove.

[0014] Preferably, the bottom plate of the lower screw is equipped with a limit sensor for detecting the position of the connecting plate. The limit sensor detects the position of the connecting hole, enabling timely and accurate detection of the connecting plate's rotation into place, and sends a signal to the controller to stop the lifting push rod. This achieves precise control of the device's movement, improves the device's automation level, and ensures that the device can safely and reliably complete the fixing and releasing operations of the windproof cable.

[0015] Preferably, the drive end of the lifting push rod is connected to a lifting adjustment handle. The operator can manually control the movement of the lifting push rod using the lifting adjustment handle, improving the flexibility and reliability of the device and ensuring effective windproof securing of the crane under any circumstances.

[0016] Preferably, the drive end of the electric push rod is connected to a push adjustment handle. When the electric push rod malfunctions or requires manual intervention, the operator can manually control the movement of the pin-shaft electric push rod by pushing the adjustment handle, further enhancing the reliability and safety of the device and avoiding safety hazards caused by the inability to timely windproof fixation of the crane due to equipment failure.

[0017] Preferably, the base is connected to an angle limiting block, and the connecting plate rests on top of the angle limiting block after it is lowered. This limits the rotation angle of the connecting plate, preventing excessive rotation that could damage the device structure or cause it to malfunction, thus improving the stability and safety of the device.

[0018] As can be seen from the above technical solution, compared with the prior art, this utility model discloses a vertical windproof cable device for a rail-mounted crane, the beneficial effects of which are: (1) Its structure is simple, easy to operate, highly automated, and has manual operation function. Under normal circumstances, it can automatically complete the fixing and release of the windproof cable. When the automatic device fails, the operator can intervene through the manual device to ensure that the crane can be firmly fixed in the strong wind environment, preventing it from moving or overturning along the track, thereby effectively avoiding equipment damage or safety accidents caused by the movement or overturning of the crane, and improving the safety and reliability of the use of rail cranes in ports, docks and other places. (2) The device also has high applicability and versatility. It can flexibly adjust the length of the cable rod according to actual needs to adapt to the fixing needs of cranes at different heights and positions. Moreover, its structural design is reasonable, making it easy to install, maintain and disassemble, thus reducing the maintenance cost and operation difficulty of the equipment.

Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] This utility model embodiment discloses a vertical windproof cable device for a rail-mounted crane, comprising: Anchoring component 1 is fixed to the ground. Anchoring component 1 includes: base 11 and connecting plate 12. The middle part of the connecting plate 12 is rotatably connected to the base 11. One end of the connecting plate 12 is provided with a connecting hole 13, and the other end is provided with a hinge shaft 14.

The electric push rod 5 is connected to the bottom of the cable rod 2. The electric push rod 5 pushes the pin out of the connecting plate 12 and the cable rod 2. The lifting push rod 3 drives the pressure rod 4 downwards. The pressure rod 4 moves and contacts the hinge pin 14, causing the connecting plate 12 to rotate. When the connecting hole 13 of the connecting plate 12 is placed in the fork-shaped groove 24 of the lower screw 23, and the connecting hole 13 is aligned with the hinge hole 25 of the lower screw 23, the electric push rod 5 drives the pin to move, connecting the lower screw 23 to the connecting plate 12. The windproof cable device is also equipped with a controller, which is connected to the vehicle sealing indicator light and the release indicator light, and controls the power supply to both.

[0024] To further optimize the above technical solution, a fixing plate 6 is hinged to the top of the cable rod 2, and the fixing plate 6 is fixedly connected to the fixing equipment.

[0025] To further optimize the above technical solution, the cable rod 2 includes an upper screw 21, an adjusting sleeve 22, and a lower screw 23; the upper screw 21 and the lower screw 23 are respectively threaded to the upper and lower ends of the adjusting sleeve 22. The threaded connection between the adjusting sleeve 22 and the upper screw 21 and the lower screw 23 facilitates the adjustment of the length of the cable rod 2.

[0026] To further optimize the above technical solution, fork-shaped grooves 24 are provided at the top of the upper screw 21 and the bottom of the lower screw 23. The fixing plate 6 and the connecting plate 12 are respectively inserted into the fork-shaped grooves 24 of the upper screw 21 and the lower screw 23, and are hinged by the screws.

[0027] To further optimize the above technical solution, a lifting guide plate 7 is connected to the bottom of the lifting push rod 3, and a guide block 41 is provided on the pressure rod 4. A guide groove 71 is opened on the surface of the lifting guide plate 7, and the guide block 41 is slidably connected in the guide groove 71. The guide groove 71 and the auxiliary guide groove 72 can guide the up and down movement of the pressure rod 4, so that the pressure rod 4 can accurately contact the hinge shaft 14 and drive the connecting plate 12 to rotate.

[0028] To further optimize the above technical solution, an auxiliary guide block 42 is also provided on the surface of the pressure rod 4, and an auxiliary guide groove 72 is provided on the surface of the lifting guide plate 7. The auxiliary guide block 42 is slidably connected in the auxiliary guide groove 72.

[0029] To further optimize the above technical solution, the bottom plate of the lower screw 23 is equipped with a limit sensor 8 for detecting the position of the connecting plate 12. The limit sensor 8 can be an inductive proximity sensor or a photoelectric proximity sensor. The limit sensor 8 can detect the distance between itself and the connecting plate 12. When the limit sensor 8 detects that the connecting plate 12 has moved to the set position, the connecting hole 13 is exactly aligned with the hinge hole 25. The lifting push rod 3 stops moving, and the pin shaft electric push rod 5 drives the pin shaft to move into the connecting hole 13 and the hinge hole 25.

[0030] To further optimize the above technical solution, a lifting adjustment handle 31 is connected to the drive end of the lifting push rod 3. The motor drive end of the lifting push rod 3 and the lifting adjustment handle 31 are connected to a single drive end, thus enabling both electric and manual drive. Various drive structures can be implemented; one example is given below. Figure 5 As shown, the drive end of the lifting motor 32 and the drive end of the lifting adjustment handle 31 are both connected to the same lifting gear 33. The lifting push rod 3 is connected to the lifting screw 34, and the lifting screw 34 is connected to the lifting gear 33.

The drive screw 54 rotates with the drive gear 53, and the rotation of the drive screw 54 can realize the forward and backward movement of the pin-shaft electric push rod 5.

[0032] To further optimize the above technical solution, the base 11 is connected to an angle limiting block 15, and the connecting plate 12 is positioned on top of the angle limiting block 15 after it falls. When the connecting plate 12 separates from the lower screw 23, the connecting plate 12 will automatically fall under the action of gravity, and the angle limiting block 15 limits the position of the connecting plate 12 after it falls.

[0033] Working principle: Move the crane to the anchor pit and press the sealing button. The lifting push rod 3 is energized, which drives the pressure rod 4 to move downward along the guide groove 71 of the lifting guide plate 7. After the pressure rod 4 contacts and engages with the hinge pin 14 of the connecting plate 12, it continues to move downward and drives the connecting plate 12 to rotate. When the connecting hole end of the connecting plate 12 rotates to be concentric with the hinge hole 25 in the fork groove 24 of the lower screw 23, the limit sensor 8 detects that the connecting plate 12 has rotated to the correct position and sends a signal to the controller. The controller controls the lifting push rod 3 to stop moving and controls the pin shaft electric push rod 5 to be energized to drive the pin shaft to move. The pin shaft passes into the connecting hole 13 and the hinge hole 25 of the lower screw 23, connecting the connecting plate 12 and the lower screw 23. The windproof cable device is still equipped with a sealing indicator light and a release indicator light. When the connecting plate 12 and the lower screw 23 are connected, the sealing indicator light lights up, and the sealing is completed.

[0034] When it is necessary to unseal the vehicle, the electric push rod 5 is energized and the pin retracts. The connecting hole end of the connecting plate 12 returns to its original position under its own weight. The lifting push rod 3 drives the pressure rod 4 to move backward. At this time, the unsealing indicator light illuminates, and the vehicle seal is released.
