[0028] The following will specifically describe the preferred embodiments of the present invention in conjunction with the accompanying drawings. The accompanying drawings form a part of this application and are used together with the embodiments of the present invention to explain the principles of the present invention, and are not used to limit the scope of the present invention.

[0029] Embodiment 1:

[0030] Please refer to Figures 1 to 3 , the present invention provides an automatic windproof cable device for large port equipment, including: a mounting base 1, an anchoring block 2, a telescopic assembly 3 and a swing assembly 4.

[0031] As Figure 1 shown, the mounting base 1 is fixedly connected to the large port equipment body. The mounting base 1 is provided with a force sensor for detecting the pre-tightening force of the rigid windproof cable and feeding back the force of the windproof cable in real time.

[0032] Furthermore, the anchoring block 2 is fixed to the foundation and the anchoring block 2 is provided with a card slot 22. The telescopic assembly 3 includes a driving assembly 31 and a clamping portion 32. The fixed end of the driving assembly 31 is rotatably connected to the mounting base 1. The clamping portion 32 is connected to the output end of the driving assembly 31 and is clamped in the card slot 22. The card slot 22 plays a guiding role and is clamped with the clamping portion 32, so that the large port equipment can transfer the wind force received to the anchoring block 2 to play a windproof role.

[0033] As Figure 3 shown, the anchoring block 2 includes two spaced-apart blocks 21. The cross-section of the block 21 is in an inverted L shape. One right-angled side of the block 21 is connected to the foundation, and the other right-angled side of the block 21 is arranged opposite to the other block 21.

[0034] Further, fixing grooves are provided at the bottoms of the other right-angled sides of the two blocks 21, and the cavity formed between the two blocks 21 is the clamping groove 22.

[0035] As Figure 2 shown, the driving assembly 31 is telescopic and has a fixed end and a telescopic end. The fixed end is rotatably connected to the mounting seat 1, and the clamping portion 32 is connected to the telescopic end and is arranged opposite to the fixing grooves of the two blocks 21.

[0036] Further, the automatic windproof cable device for large port equipment further includes a swinging assembly 4. The swinging assembly 4 is respectively connected to the large port equipment body and the driving assembly 31, and is used to drive the driving assembly 31 and the clamping portion 32 to swing integrally around a specified direction and a specified angle, and to make the clamping portion 32 be clamped in the clamping groove 22.

[0037] As Figure 7 、 Figure 8 shown, the swinging assembly 4 includes a vertical rod 41, a connecting rod 42 and a second linear driving member 43. One end of the vertical rod 41 is rotatably connected to the mounting seat 1, and the other end of the vertical rod 41 is connected to the driving assembly 31. One end of the connecting rod 42 is hinged to the large port equipment body, and the other end of the connecting rod 42 is connected to the vertical rod 41.

[0038] Further, a fixing hole 421 is provided at the other end of the connecting rod 42, and the connecting rod 42 is sleeved on the vertical rod 41 through the fixing hole 421. The fixed end of the second linear driving member 43 is hinged to the large port equipment body, and the output end is hinged to the other end of the connecting rod 42.

[0039] As Figure 7 、 Figure 8 shown, the swinging assembly 4 further includes a stop block 44. The stop block 44 is fixedly connected to the large port equipment body and is arranged between the connecting rod 42 and the second linear driving member 43. The second linear driving member 43 is a hydraulic cylinder, and the moving end of the hydraulic cylinder can move along its extension or contraction.

[0040] Further, when the moving end of the second linear driving member 43 is in the contracted state, the stop block 44 abuts against one side of the fixing hole 421, so as to prevent the contraction of the second linear driving member 43 from driving the fixing hole 421 to continue to move closer to the large port equipment body and cause irreversible movement.

[0041] As Figure 4 、 Figure 6As shown in the figure, the driving component 31 includes a support base 311, a rotating block 3131, a screw 313, a first driving member 312, a pull rod 314 and a guide sleeve 315. The support base 311 is rotatably connected to the mounting base 1. A stepped hole is formed at the bottom of the support base 311. The large-diameter section of the stepped hole is closer to the mounting base 1 than the small-diameter section. The rotating block 3131 is rotatably disposed inside the large-diameter section of the stepped hole. One end of the screw 313 rotatably passes through the small-diameter section of the stepped hole and is connected to the rotating block 3131.

[0042] Further, the first driving member 312 is fixed to the support base 311 and its output shaft is connected to the screw 313 for driving the screw 313 to rotate along its own axis. The pull rod 314 is provided with a first threaded hole relative to the screw 313. One end of the pull rod 314 is threadedly connected to the other end of the screw 313. The other end of the pull rod 314 is connected to the clamping block. The cross section of the pull rod 314 is polygonal. The guide sleeve 315 is fitted over the pull rod 314 and connected to the large port equipment body.

[0043] As Figure 5 shown in the figure, at least one second threaded hole is formed in the outer wall of the pull rod 314 in the radial direction. The second threaded hole is disposed opposite to the inner wall of the guide sleeve 315. The telescopic assembly 3 further includes at least one filling member, and the filling members are provided in one-to-one correspondence with the second threaded holes.

[0044] Further, the filling member includes a filling block 3151 and a screw. The filling block 3151 is disposed between the guide sleeve 315 and the pull rod 314, and its two ends respectively abut against the inner wall of the guide sleeve 315 and the outer wall of the pull rod 314. The filling block 3151 is provided with a countersunk hole relative to the second threaded hole. The threaded end of the screw rotatably passes through the countersunk hole and is threadedly connected to the second threaded hole. The head of the screw is disposed inside the large-diameter end of the countersunk hole. The guide sleeve 315 is used to prevent the rigid windproof cable from rotating and plays a guiding role.

[0045] As Figure 4 shown in the figure, the first driving member 312 includes a reducer 3121 and a motor 3122. The output shaft of the motor 3122 is connected to the input shaft of the reducer 3121. The output shaft of the reducer 3121 is fixedly connected to the screw 313.

[0046] Further, the driving component 31 can also be other forms of linear driving members, such as a linear push rod motor 3121, which elongates or contracts along the telescopic assembly 3 for causing the clamping portion 32 to slide into or away from the card slot 22. No further elaboration is made here.

[0047] As Figure 2As shown in the figure, the automatic anti-wind cable device for large port equipment further includes a limit component 5. The limit component 5 includes a first travel switch 51, a second travel switch 52 and a lever 33. Both the first travel switch and the second travel switch 52 are connected to the large port equipment body, and the second travel switch 52 is arranged directly below the first travel switch 51. One end of the lever 33 is connected to the pull rod 314.

[0048] Further, when one end of the lever 33 touches the second travel switch 52, the pull rod 314 stops sliding downwards. When the other end of the lever 33 touches the first travel switch 51, the pull rod 314 stops sliding upwards. The limit component 5 is used to monitor the telescopic stroke of the telescopic component 3 and send commands for the loosening and pre-tightening states of the anti-wind cable device to the large port equipment electric control system.

[0049] The specific working process of the present invention is as follows: The mounting seat 1 is fixedly connected to the large port equipment body and is used to bear the force of the anti-wind cable. The mounting seat 1 is provided with a force sensor for detecting the pre-tightening force of the rigid anti-wind cable and real-time feedback of the force on the anti-wind cable. The anchoring block 2 is fixed to the foundation, and the anchoring block 2 is provided with a card slot 22. The anchoring block 2 is used for the large port equipment to transfer the wind force received through the clamping part 32 to the anchoring block 22, playing a role in preventing wind.

[0050] Further, the telescopic component 3 includes a driving component 31 and a clamping part 32. The driving component 31 is telescopic and has a fixed end and a telescopic end. The fixed end is rotatably connected to the mounting seat 1. The clamping part 32 is connected to the telescopic end and is arranged opposite to the fixed slots of the two blocks 21. The clamping part 32 is connected to the output end of the driving component 31 and is clamped in the card slot 22, which is used to prevent the rotation of the rigid anti-wind cable and play a guiding role. The cable hook is used in cooperation with the anchoring block 2. When the large port equipment needs to enter the typhoon prevention state, the cable hook hooks the anchoring block 2, transfers the wind force borne by the large port equipment to the anchoring block 2, and then to the foundation.

[0051] The swing component 4 is connected to the driving component 31 part of the large port equipment body and the telescopic component 3, and is used to drive the driving component 31 and the clamping part 32 part of the telescopic component 3 to swing integrally around a specified direction and a specified angle. The limit component 5 is connected to one side of the large port equipment body and is used to monitor the telescopic stroke of the telescopic component 3 and send commands for the loosening and pre-tightening states of the anti-wind cable device to the large port equipment electric control system.

[0052] When entering the windproof state, the user drives the swing assembly 4, and the second linear drive 43 extends to a specified length. Supported by the connecting rod 42, the swing assembly 4 rotates along the hinge end of the connecting rod 42. At this time, the swing assembly 4 drives the telescopic assembly 3 to swing a specified angle relative to the large port equipment body and intersects and coincides with the extension line of the anchoring block 2. When the windproof cable moves to the vicinity of the anchoring block 2 along with the large port equipment body, the drive assembly 31 drives the screw 313 to rotate. The pull rod 314 is threadedly connected to the screw 313 and drives the pull rod 314 to rotate. Since there is also a filling block 3151 between the pull rod 314 and the guide sleeve 315, the pull rod 314 is restricted to slide only away from or close to the anchoring block 2.

[0053] Further, at this time, the telescopic assembly 3 is in the extended state and when it extends to the specified length, the toggle lever 33 abuts against the second travel switch 52. At the same time, the clamping portion 32 slides along the card slot 22 and abuts against the edge of the fixed slot of the anchoring block 2, and the drive member stops extending. The user drives the drive member to move in the direction close to the swing assembly 4. The clamping portion 32 slides along the fixed slot and is completely inserted into the fixed slot and generates a pre-tightening force. At the same time, the sensor arranged on the mounting seat 1 feeds back a pressure signal. When the specified pre-tightening force is reached, the drive member stops working.

[0054] When the windproof task is completed, the user drives the first drive member 312 to drive the telescopic assembly 3 to first move in the direction away from the swing assembly 4 until the toggle lever 33 abuts against the second travel switch 52, so that the clamping portion 32 is separated from the fixed slot. Then, the large port equipment is driven away from the anchoring block 2. Finally, the telescopic assembly 3 is driven to move in the direction close to the swing assembly 4 and the second linear drive 43 is contracted to the shortest until the toggle lever 33 abuts against the first travel switch 51. At this time, the cable device is completely retracted and in the initial state.

[0055] Embodiment 2:

[0056] As Figure 9 shown, the same parts between Embodiment 2 and Embodiment 1 will not be elaborated. The differences between Embodiment 2 and the embodiment are that according to different windproof requirements, the cable device may also include: a mounting seat 1, an anchoring block 2 and a telescopic assembly 3.

[0057] The cable device includes a vertical rod. One end of the vertical rod is connected to the mounting seat 1 and the other end is fixedly connected to the telescopic assembly 3.

[0058] As shown in the figure, the telescopic assembly 3 and the anchoring block 2 are arranged below the mounting seat 1 and are arranged in the vertical direction projection relative to the large port equipment body. The mounting seat 1 is fixedly connected to the large port equipment body. One end of the vertical rod is hinged to the mounting seat 1. The support seat of the telescopic assembly 3 is fixedly connected to the other end of the vertical rod. The anchoring block 2 is vertically arranged along the extension line direction of the telescopic assembly 3 and is fixedly connected to the foundation.

[0059] As shown Figure 9 in the figure, the extension lines of the mounting base 1, the vertical rod, and the telescopic assembly 3 are always in a straight line and move along with the large port equipment body in the direction of approaching or departing from the slot of the anchoring block 2. When the clamping portion 32 of the telescopic assembly 3 abuts against the anchoring block 2, the mounting base 1, the vertical rod, the telescopic assembly 3, and the anchoring block 2 are in the same straight line.

[0060] For the specific working process of the present invention, when entering the windproof state, the user operates the cable device to slide along the guide rail together with the large port equipment. When receiving the signal to approach the anchoring block 2, the user drives the first driving member 313. At the same time, the screw 313 rotates to drive the pull rod 314 and the clamping portion 32 to move closer to the anchoring block 2. When the centers of the pull rod 314 and the anchoring block 2 are in a straight line, the user stops the movement of the large port equipment. At this time, the lever 33 abuts against the second travel switch 52, and reversely drives the pull rod 314 and the clamping portion 32 to contract and move in the direction close to the large port equipment until the clamping portion 32 abuts against and is placed in the fixing groove of the anchoring block 2. At this time, the pre-tightening force of the telescopic assembly is recorded by the sensor, and the large port equipment enters the windproof state.

[0061] When the windproof task is completed, the user first drives the first driving member 312 to drive the telescopic assembly 3 to move in the direction away from the large port equipment body until the lever 33 abuts against the second travel switch 52, so that the clamping block 32 is separated from the fixing groove. Then, the large port equipment is driven away from the anchoring block 2. Finally, when it moves to the lever 33 abutting against the first travel switch 51, the driving of the telescopic assembly 3 is stopped finally, and the cable device returns to the initial state, thus completing the windproof task.

[0062] The above is only the preferred specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any changes or substitutions that can be easily thought of by those skilled in the art within the technical scope disclosed by the present invention should be covered within the protection scope of the present invention.
