Description

Technical Field

[0001] The present invention relates to the technical field of ship feeding facilities, in particular to a ship side cable conveying device. Background Art

[0002] High-voltage shore power facilities have gradually become standard equipment at mainstream ship ports and terminals, and are also commonly installed on major cargo vessels such as refrigerated container ships. While docked, high-voltage shore power flexible cables are laid from the ship's shore power winch to the shore power supply box at the terminal using a cable conveyor. However, due to the varying locations of the power receiving point on the ship's side relative to the terminal, the cable conveyor cannot be quickly adjusted to suit different ship types, limiting its applicability.

[0003] In order to solve the above problems, the existing technology has designed a cable conveying device, which includes a base plate, a vertical plate, a telescopic assembly, a guide frame and a guide wheel. By arranging a telescopic assembly between the vertical plates on both sides, which is driven by a telescopic drive to change the pitch angle, the telescopic assembly can be accurately extended to the cable output point, thereby improving the applicability of the cable conveying device.

[0004] However, because the telescopic actuator is mounted on the fixed end of the telescopic assembly, when the telescopic assembly is extended outward to a certain length, the distance between the extended end of the telescopic assembly and the hydraulic cylinder is relatively large. At this time, due to the lack of external support, the extended end of the telescopic assembly is prone to swaying and becoming unstable. Furthermore, because the telescopic actuator is connected to the lower portion of the telescopic assembly and is mounted on the vertical plates on both sides, the telescopic assembly cannot be retracted to its vertical position by the hydraulic cylinder after operation. At this time, the extended end of the telescopic assembly is close to the ship's deck and forms a certain angle with it, causing the entire cable conveying device to occupy a large amount of space on the ship when not in operation. Therefore, there is an urgent need for a shipboard cable conveying device with high stability and minimal deck space. Summary of the Invention

[0005] The object of the present invention is to provide a ship side cable conveying device to solve the technical problems in the prior art of the instability of the telescopic platform of the ship side cable conveying device and the large space occupied by the ship side cable conveying device.

[0006] As conceived above, the technical solution adopted by the present invention is:

[0007] A shipboard cable conveying device, comprising:

[0008] A column, wherein the column is fixedly arranged on the hull;

[0009] a telescopic assembly comprising a fixing member, a sleeve, a telescopic driver, and a telescopic platform, wherein the fixing member is disposed on the hull; the sleeve is rotatably connected to the fixing member, the telescopic driver is disposed on the sleeve, the telescopic platform is slidably connected to the sleeve, and the telescopic platform can slide relative to the sleeve under the drive of the telescopic driver;

[0010] A pulley assembly, the pulley assembly comprising a supporting pulley group and a guide pulley group, the supporting pulley group being arranged on the telescopic platform, and the guide pulley group being arranged on the column;

[0011] A driving mechanism, the driving mechanism includes a winding drive and a rope arranged at the output end of the winding drive. In the direction away from the winding drive, the rope is sequentially wound around the guide pulley group and the support pulley group and then connected to the telescopic platform. The winding drive can drive the telescopic assembly to switch between the retracted position and the use position by retracting and releasing the rope. When the telescopic assembly is in the use position, the vertical height of the support pulley group is lower than the vertical height of the guide pulley group.

[0012] Furthermore, the supporting pulley group includes a first supporting pulley and a second supporting pulley; the guide pulley group includes a first guide pulley and a second guide pulley; two strands of the rope are provided at the output end of the winding drive, and along the direction away from the winding drive, one strand of the rope is sequentially wound around the first guide pulley and the first supporting pulley and then connected to the telescopic platform, and the other strand of the rope is sequentially wound around the second guide pulley and the second support pulley and then connected to the telescopic platform.

[0013] Furthermore, a locking piece is provided on the column, and the locking piece can lock the rope.

[0014] Furthermore, the ship's side cable conveying device also includes a support member, which is fixed on the hull. When the telescopic assembly is in the use position, the support member supports the sleeve.

[0015] Furthermore, a rubber pad is provided on the top of the support member.

[0016] Furthermore, a first limiting member is provided on the column, and when the telescopic assembly is in the retracted position, the first limiting member abuts against one side of the sleeve.

[0017] Furthermore, a second limiting member is provided on the sleeve, and the second limiting member is used to limit the extension length of the telescopic platform relative to the sleeve.

[0018] Furthermore, the shipboard cable conveying device also includes a guide assembly, which is connected to the telescopic platform and is configured to guide the cable.

[0019] Furthermore, the guide assembly includes:

[0020] a guide frame connected to the telescopic platform;

[0021] A guide wheel is rotatably arranged on the guide frame.

[0022] Furthermore, the guide assembly also includes a pressure sensor. A support shaft is provided on the guide frame. The guide wheel is rotatably provided on the support shaft. The pressure sensor is configured to detect the pressure of the guide wheel on the support shaft.

[0023] Beneficial effects of the present invention:

[0024] The present invention provides a shipboard cable conveying device, which comprises a support pulley assembly provided on a telescopic platform, a guide pulley assembly provided on a column, and a drive mechanism provided thereon. The drive mechanism is provided with a rope, which sequentially connects the drive mechanism, the column, and the telescopic platform. The drive mechanism retracts and releases the rope to achieve the retraction and extension of the telescopic assembly. During use, the drive mechanism releases the rope, and the telescopic assembly is extended to a horizontal position. The telescopic drive drives the telescopic platform to slide outward relative to the sleeve until the telescopic platform accurately extends to the cable output point and stops. At this time, due to the support pulley assembly provided on the telescopic platform, the rope exerts tension on the telescopic platform through the support pulley assembly. The telescopic platform is more stable and less prone to shaking due to the combined force of the sleeve support and the rope tension. During retraction, the drive mechanism retracts the rope, and the telescopic assembly rotates from a horizontal position to a vertical position around a fixed member under the traction of the rope. At this time, the entire shipboard cable conveying device occupies less space on the ship's deck. Therefore, the shipboard cable conveying device provided by the present invention achieves high stability and small space occupation on the ship's deck. BRIEF DESCRIPTION OF THE DRAWINGS

[0044] The technical solution of the present invention will be further described below with reference to the accompanying drawings and through specific implementation methods.

[0045] like Figure 1-Figure 4 As shown, the present invention provides a shipboard cable conveying device, which includes a column 1, a telescopic component 2, a pulley component 3 and a driving mechanism 4.

[0046] like Figure 1 As shown, the column 1 is fixedly arranged on the hull 100; the telescopic assembly 2 includes a fixing member 20, a sleeve 21, a telescopic drive 22 and a telescopic platform 23, the fixing member 20 is arranged on the hull 100; the sleeve 21 is rotatably connected to the fixing member 20, the telescopic drive 22 is arranged on the sleeve 21, and the telescopic platform 23 is slidably connected to the sleeve 21. The telescopic platform 23 can slide relative to the sleeve 21 under the drive of the telescopic drive 22; the pulley assembly 3 includes a supporting pulley group 31 and a guide pulley group 32, the supporting pulley group 31 is arranged on the telescopic platform 23, and the guide pulley group 32 is arranged on the column 1; the driving mechanism 4 includes a winding drive and a rope 41 provided at the output end of the winding drive. In a direction away from the winding drive, the rope 41 is sequentially wound around the guide pulley block 32 and the support pulley block 31 and then connected to the telescopic platform 23. The winding drive can drive the telescopic assembly 2 to switch between the retracted position and the use position by retracting and releasing the rope 41. When the telescopic assembly 2 is in the use position, the vertical height of the support pulley block 31 is lower than the vertical height of the guide pulley block 32. The sleeve 21 and the telescopic platform 23 both extend in the horizontal direction. Driven by the telescopic drive 22, the telescopic platform 23 can slide horizontally relative to the sleeve 21.

[0047] By setting a supporting pulley group 31 on the telescopic platform 23, setting a guide pulley group 32 on the column 1, and then setting a driving mechanism 4, a rope 41 is provided on the driving mechanism 4. The driving mechanism 4 is connected to the column 1 and the telescopic platform 23 in sequence through the rope 41. The telescopic component 2 can be folded and unfolded by using the driving mechanism 4 to retract and release the rope 41. When in use, the driving mechanism 4 releases the rope 41, the telescopic component 2 is unfolded to the horizontal state, and the telescopic driver 22 drives the telescopic platform 23 to slide outward relative to the sleeve 21 until the telescopic platform 23 is accurately extended to the cable output point and stops. At this time, since the supporting pulley group 31 is provided on the telescopic platform 23, the rope 41 can apply tension to the telescopic platform 23 through the supporting pulley group 31. The telescopic platform 23 is more stable and not easy to shake under the combined action of the supporting force of the sleeve 21 and the tension of the rope 41; when retracting, the driving mechanism 4 retracts the rope 41, and the telescopic component 2 rotates from the horizontal state to the vertical state with the fixed 20 as the axis under the traction of the rope 41. At this time, the entire ship's side cable conveying device occupies less space on the ship's deck. Therefore, the ship's side cable conveying device proposed by the present invention can achieve the effect of high stability and small space occupation on the ship's deck.

[0048] In this embodiment, the telescopic actuator 22 is a hydraulic cylinder. In other embodiments, the telescopic actuator 22 can also be an electric cylinder.

[0049] Specifically, the support pulley assembly 31 includes a first support pulley 311 and a second support pulley 312; the guide pulley assembly 32 includes a first guide pulley 321 and a second guide pulley 322; and two ropes 41 are provided at the output end of the winding drive. Moving away from the winding drive, one rope 41 is sequentially wound around the first guide pulley 321 and the first support pulley 311 before being connected to the telescopic platform 23. The other rope 41 is sequentially wound around the second guide pulley 322 and the second support pulley 312 before being connected to the telescopic platform 23. Because the two ropes 41 exert tension on the telescopic platform 23, the telescopic platform 23 remains more stable when in its operational position.

[0050] More specifically, the winding drive includes a motor and a roller arranged at the output end of the motor, and the rope 41 is wound around the roller.

[0051] like Figure 1As shown, in this embodiment, two rollers are provided on the winding drive. At the same time, in this embodiment, the pulley assembly 3 also includes a positioning guide pulley 30 for changing the winding direction of the rope 41. Two pulleys are provided on the positioning guide pulley 30, and two pulleys are also provided on the first support pulley 311. A rope 41 extends from a roller on the winding drive, and is successively wound around a pulley in the positioning guide pulley 30, the first guide pulley 321, a pulley in the first support pulley 311, the second support pulley 312, another pulley in the first support pulley 311, the second guide pulley 322 and another pulley in the positioning guide pulley 30, and finally returns to the other roller of the winding drive. Finally, one rope 41 forms two ropes 41 extending from the winding drive. One of the two ropes 41 is successively wound around one of the positioning guide pulleys 30, the first guide pulley 321, and one of the first support pulleys 311, and then connected to the telescopic platform 23. The other rope 41 is successively wound around the other pulley of the positioning guide pulley 30, the second guide pulley 322, the other pulley of the first support pulley 311, and the second support pulley 312, and then connected to the telescopic platform 23. The arrangement of the positioning guide pulley 30 and the first support pulley 311 ensures that the two ropes 41 do not interfere with each other during the process of connecting to the telescopic platform 23. During operation, the drive mechanism drives the two rollers to rotate simultaneously and in the same direction, driving the two ropes 41 to retract and extend simultaneously, thereby achieving the retraction and deployment of the telescopic assembly 2. The two ropes 41 can also apply two pulling forces to the telescopic platform 23, making the telescopic platform 23 more stable during the process of retracting and deploying.

[0052] In another embodiment, the arrangement of the rope 41 is not limited to one rope wound into two strands. The rope 41 can also be directly arranged into two strands, with the two ropes 41 extending from the winding drive respectively and finally connected and fixed to the telescopic platform 23.

[0053] In another embodiment, multiple ropes 41 may be provided, and the number of pulleys on the guide positioning pulley 30, the guide pulley assembly 32, and the support pulley assembly 31 may also be adapted accordingly. For example, when the telescopic platform 23 is long, three ropes 41 may be provided, the positioning guide pulley 30 may be provided with three pulleys, the guide pulley assembly 32 may include three guide pulleys, each of which may be provided with a pulley, and the support pulley assembly 31 may include three support pulleys, each of which may be provided with a pulley. Three ropes 41 are provided. The first rope 41 is wound around the first pulley in the positioning guide pulley 30, the first guide pulley in the guide pulley block 32, and the first support pulley in the support pulley block, and then connected to the telescopic platform 23. The second rope 41 is wound around the second pulley in the positioning guide pulley 30, the second guide pulley in the guide pulley block 32, and the second support pulley in the support pulley block, and then connected to the telescopic platform 23. The third rope 41 is wound around the third pulley in the positioning guide pulley 30, the third guide pulley in the guide pulley block 32, and the third support pulley in the support pulley block, and then connected to the telescopic platform 23. When the telescopic platform 23 is long, the drive mechanism can simultaneously drive the three ropes 41 to apply three pulling forces to the telescopic platform 23, thereby ensuring that the telescopic platform 23 remains stable during deployment and retraction.

[0054] More specifically, a locking member 5 is provided on the column 1, which can lock the rope 41. When the telescopic assembly 2 is unfolded and the telescopic platform 23 reaches the output point of the cable 200, the release of the rope 41 is stopped, and the locking member 5 is used to lock the rope 41 to prevent the rope 41 from shaking or moving, thereby ensuring the stability of the telescopic assembly 2.

[0055] In this embodiment, the locking member 5 is located between the winding drive and the guide pulley group 32 in the vertical direction, and can lock two ropes 41 at the same time. It is a conventional clamping mechanism in this field. The two clamping jaws are rotatably connected and driven by a spring to clamp and lock the rope 41.

[0056] Specifically, the shipboard cable conveying device further includes a support member 6, which is fixed to the hull 100. When the telescopic assembly 2 is in the use position, the support member 6 supports the sleeve 21. The support member 6 not only limits the position of the telescopic assembly 2, but also supports the telescopic assembly 2, making the telescopic assembly 2 more stable.

[0057] More specifically, a rubber pad is provided on the top of the support member 6. The rubber pad can firstly play a buffering role to prevent the telescopic component 2 from rotating and falling too fast to cause squeezing damage to the support member 6, and secondly can also protect the sleeve 21 from being worn.

[0058] Specifically, a first position-limiting member 7 is provided on the column 1 . When the telescopic assembly 2 is in the retracted position, the first position-limiting member 7 abuts against one side of the sleeve 21 to ensure that the telescopic assembly 2 is retracted into place.

[0059] More specifically, a second limiter 8 is provided on the sleeve 21, and the second limiter 8 is used to limit the extension length of the telescopic platform 23 relative to the sleeve 21 to ensure that the telescopic platform 23 can accurately reach the output point of the cable 200 without moving, thereby improving the transmission quality of the cable 200.

[0060] like Figure 3-Figure 4 As shown, the shipboard cable conveying device also includes a guide assembly 9, which is connected to the telescopic platform 23 and is configured to guide the cable 200 to prevent the cable 200 from deviating during the conveying process or even sliding off the telescopic platform 23.

[0061] Specifically, the guide assembly 9 includes a guide frame 91 and a guide wheel 92. The guide frame 91 is connected to the telescopic platform 23. The guide wheel 92 is rotatably set on the guide frame 91. The guide frame 91 is used to limit the output direction of the cable 200. The guide wheel 92 is used to prevent the cable 200 from being worn during transportation.

[0062] More specifically, the guide assembly 9 also includes a pressure sensor 93. A support shaft is provided on the guide frame 91. The guide wheel 92 is rotatably provided on the support shaft. The pressure sensor 93 is configured to detect the pressure of the guide wheel 92 on the support shaft. When the pressure detected by the pressure sensor 93 exceeds the alarm value, a signal is sent to the controller. The controller controls the retraction and release operations of the cable 200 to reduce the pressure on the guide assembly 9 and prevent damage to the cable 200 due to external factors such as ship drift. The controller can also use an alarm device to sound and light alarms to remind the operator to intervene.

[0063] like Figure 2 As shown, in this embodiment, two guide plates 231 are provided on the telescopic platform 23, and two first guide wheels 232 are provided between the two guide plates 231. The arrangement of the two guide plates 231 can prevent the cable 200 from slipping off the telescopic platform 23 and smoothly transport the cable 200 to the guide device 9. At the same time, the two first guide wheels 232 can reduce the transport resistance of the cable 200 and protect the cable 200 from wear.

[0064] In other embodiments, three, four, or more first guide wheels 232 may be provided.

[0065] like Figure 2 As shown, in this embodiment, a second guide wheel 233 is further provided on the telescopic platform 23 to prevent the cable 200 from contacting and causing wear on the corners of the telescopic platform 23 when it moves from the telescopic platform 23 to the guide device 9.

[0066] In this embodiment, the rope 41 is a steel wire rope with high strength, good toughness and wear resistance.

[0067] In other embodiments, the rope 41 may also be a nylon rope, a white-brown rope, etc.

[0068] In this embodiment, the working process of the shipboard cable guide device is as follows:

[0069] Initially, the telescopic assembly 2 is in the retracted position, and the locking member 5 is adjusted to release the rope 41 so that the telescopic assembly 2 is in a rotatable state.

[0070] Then, the driving mechanism 4 continuously releases the rope 41 through the winding drive, and the telescopic assembly 2 is rotated and lowered to the use position around the fixing member 20 as the central axis under the traction of the rope 41. At this time, the support member 6 abuts against one side of the sleeve 21.

[0071] Next, the telescopic driver 22 is turned on, and the telescopic driver 22 drives the telescopic platform 23 to extend outward to the output point of the cable 200 and stop. The telescopic platform 23 is then limited by the second limiting member 8, and the rope 41 is locked by the locking member 5.

[0072] Next, the cable 200 is transported from the ship to the shore. The cable 200 extends through the sleeve 21 to the telescopic platform 23 and passes through the first guide wheel 232 and the second guide wheel 233 under the limiting guidance of the guide plate 231.

[0073] Finally, the cable 200 reaches the guide device 9, and under the limiting guidance of the guide frame 91, passes through the guide wheel 92 and is finally transported to the shore.

[0074] Obviously, the above embodiments of the present invention are merely examples for the purpose of clearly illustrating the present invention and are not intended to limit the embodiments of the present invention. A person skilled in the art would be able to make various obvious changes, readjustments, and substitutions without departing from the scope of protection of the present invention. It is not necessary and impossible to enumerate all embodiments here. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention shall be included within the scope of protection of the claims of the present invention.
