[0060] In order to enable those skilled in the art to better understand the present invention, thereby making a clearer definition of the scope of protection of the present invention, the present invention is described in detail below with respect to certain specific embodiments of the present invention. It should be noted that the following are only certain specific embodiments of the present invention, which are only part of the embodiments of the present invention, wherein the specific and direct description of the relevant structures is only for the convenience of understanding the present invention, and each specific feature does not naturally and directly limit the scope of implementation of the present invention. Conventional selections and replacements made by those skilled in the art under the guidance of the present invention should all be deemed to be within the scope of protection of the present invention.

[0061] like Figure 1-Figure 5 、 Figure 7 As shown, the present invention discloses a shore power winch with a self-protection function, comprising:

[0062] Rack 1;

[0063] The winding drum 2 is rotatably mounted on the frame 1, and the axial direction of the winding drum 2 is along the front-to-back direction. The winding drum 2 includes a first winding drum portion 21, a second winding drum portion 22 located at the front end of the first winding drum portion 21, and a first partition plate 24 located between the first winding drum portion 21 and the second winding drum portion 22. The first partition plate 24 is provided with a first notch 241 extending through the first winding drum portion 21 and the second winding drum portion 22.

[0064] A driving device 3, which is used to drive the winding drum 2 to rotate;

[0065] The elastic protection assembly 4 is disposed on the second winding drum portion 22 and includes a rotating frame 41 and a reset member 42. The rotating frame 41 is rotatably disposed on the second winding drum portion 22 and is provided with a steering portion 419. The reset member 42 is used to connect the rotating frame 41 and the winding drum 2 and to drive the rotating frame 41 to rotate so that the rotating frame 41 is away from the first notch 241.

[0066] The cable 5 includes a first line segment 51 and a second line segment 52. The first line segment 51 is wound around the outer circumference of the first winding drum portion 21. A plug portion 511 is provided at one end of the first line segment 51. The second line segment 52 is provided around the outer circumference of the second winding drum portion 22. The second line segment 52 includes an elastic segment 521, a first turning segment 522 and an adaptor segment 523 connected in sequence, wherein the other end of the first line segment 51 and the end of the elastic segment 521 facing away from the first turning segment 522 are connected through a first notch 241, and the elastic segment 521 extends from one end of the first notch 241 in a clockwise arc and connects to the first turning segment 522 at the turning portion 419. Under the action of the turning portion 419, the first turning segment 522 extends outward along the radial direction of the winding reel 2 and is connected to one end of the adaptor segment 523. The adaptor segment 523 extends from one end of the turning portion 419 in a counterclockwise arc and approaches the first notch 241.

[0067] Therefore, the driving device 3 works to rotate the winding drum 2, and the cable 5 is unwound so that the first wire segment 51 wound on the outer periphery of the first winding drum portion 21 is extended to a certain length, so that the plug portion 511 can be extended to the power supply pile for power connection. In addition, when the ship shakes or the like and the first wire segment 51 is pulled, the first wire segment 51 will pull the elastic segment 521, so that the elastic segment 521 is pulled from the outer periphery of the second winding drum portion 22 into the outer periphery of the first winding drum portion 21 through the first notch 241, so as to increase the length through the combination of the first wire segment 51 and the elastic segment 521 pulled into the first winding drum portion 21, thereby preventing the cable 5 from being damaged. Excessive traction force causes damage to the connection between the plug part 511 and the power supply pile, as well as the connection between the cable 5 and the winding reel 2. In addition, since the elastic segment 521 is pulled, the length of the elastic segment 521 in the second winding drum part 22 is reduced, so that the rotating frame 41 is driven to rotate and the steering part 419 is close to the first notch 241 to allow the reset member 42 to accumulate elastic potential energy. When the first line segment 51 is loosened during the subsequent shaking of the ship, the reset member 42 will drive the rotating frame 41 to rotate and recover at least part of the elastic segment 521 to ensure that the second line segment 52 on the outer periphery of the second winding drum part 22 is the longest and safer to deal with the situation where the first line segment 51 is pulled.

[0068] Specifically, the rotating frame 41 is provided with an arc-shaped first reset cavity 411, and a first abutting portion 4111 is provided at one end of the arc of the first reset cavity 411. The winding reel 2 is located in the first reset cavity 411 and is provided with a first positioning member 412. The reset member 42 includes a compression spring 421 provided in the first reset cavity 411, one end of the compression spring 421 abuts against the first abutting portion 4111, and the other end abuts against the first positioning member 412. The other end of the arc of the first reset cavity 411 is provided with a first positioning portion 4112. When the first positioning member 412 abuts against the first positioning portion 4112, the distance between the steering portion 419 and the first notch 241 reaches the minimum. The rotating frame 41 is provided with an arc-shaped second reset chamber 413, and a second hook portion 4131 is provided at one end of the arc of the second reset chamber 413. The winding reel 2 is located in the second reset chamber 413 and is provided with a second positioning member 414. The reset member 42 includes a tension spring 422 provided in the second reset chamber 413, one end of the tension spring 422 is hooked to the second hook portion 4131, and the other end is hooked to the second positioning member 414. The other end of the arc of the second reset chamber 413 is provided with a second positioning portion 4132. When the second positioning member 414 abuts against the second positioning portion 4132, the distance between the turning portion 419 and the second notch 251 is minimized. Among them, the first abutting portion 4111, the first positioning member 412, the first positioning portion 4112, the second positioning portion 4132, the second positioning member 414, and the second hook portion 4131 are arranged in sequence along the circumference of the winding reel 2.

[0069] Therefore, under the restoring force of the compression spring 421 and the tension spring 422, the first positioning member 412 is driven toward the first positioning portion 4112 to complete the positioning. At this time, the distance between the turning portion 419 and the first notch 241 reaches the maximum, that is, the second line segment 52 has the maximum length for elastic compensation. When the first line segment 51 is pulled so that the second line segment 52 extends from the first notch 241, the rotating frame 41 rotates to make the first positioning member 412 and the first positioning portion 4112 move away from each other, and the second positioning member 41 4 and the second positioning portion 4132 approach each other and are positioned when the second positioning member 414 and the second positioning portion 4132 abut against each other. At this time, the distance between the turning portion 419 and the first notch 241 is minimized, and the elastic potential energy of the compression spring 421 and the tension spring 422 is maximized. When the traction force on the first wire segment 51 decreases, the compression spring 421 and the tension spring 422 can be elastically reset to drive the rotating frame 41 to reset, thereby increasing the length of the second wire segment 52 on the second winding drum portion 22 to ensure safety.

[0070] In addition, combined Figure 6 、 Figure 8 As shown, the winding reel 2 further includes a third winding drum portion 23 located at the front end of the second winding drum portion 22 and a second partition plate 25 located between the second winding drum portion 22 and the third winding drum portion 23, wherein a second notch 251 is provided through the second partition plate 25 in the front-to-back direction;

[0071] The cable 5 also includes a third line segment 53, which is arranged on the outer periphery of the third winding drum portion 23, and one end of the third line segment 53 is fixed to the winding reel 2, and is connected to electricity through this end, and stable conduction of the circuit is ensured by means of a slip ring, and the other end of the third line segment 53 and the end of the adapter segment 523 facing away from the first turning segment 522 are connected through a second notch 251, and the third line segment 53 includes at least two growth segments 531 and at least one second turning segment 532. This embodiment specifically adopts 4 growth segments 531 and 3 second turning segments 532, each growth segment 531 is arranged radially outward along the third winding drum portion 23, and each growth segment 531 is in the shape of an arc extending circumferentially along the third winding drum portion 23, and the second turning segment 532 connects two adjacent growth segments 531 toward the same end, so that the third line segment 53 is arranged in a reciprocating folding manner as a whole;

[0072] The device further includes at least one elastic positioning member 6. In this embodiment, three elastic positioning members 6 are used. Each elastic positioning member 6 is disposed between two adjacent growth sections 531 and is close to or abuts against the second turning section 532. The elastic positioning member 6 is used to restrict the movement of the second turning section 532.

[0073] When the adapting section 523 is pulled away from the second notch 251 , the extending section 531 is pulled from the outer periphery of the third bobbin portion 23 into the outer periphery of the second bobbin portion 22 through the second notch 251 , causing the second turning section 532 to pass over the elastic positioning member 6 .

[0074] Therefore, when the first line segment 51 is pulled due to the shaking of the ship, when the required compensation length of the pulling is short, it can be compensated only by the movement of the elastic protection component 4. When the compensation of the elastic protection component 4 is still insufficient, a large pulling force is generated in the first line segment 51. This pulling force causes the second turning segment 532 to forcibly pass over the elastic positioning member 6 and release the movement restriction of the second turning segment 532, so that the two extension segments 531 connected by the second turning segment 532 can pass through the second notch 251 from the third winding line. The outer periphery of the barrel portion 23 is pulled into the outer periphery of the second winding barrel portion 22. With the compensation of the growth segment 531, the second line segment 52 can be completely pulled from the outer periphery of the second winding barrel portion 22 into the outer periphery of the first winding barrel portion 21 through the first notch 241 to increase the length through the combination of the first line segment 51 and the second line segment 52, and the growth segment 531 can also be pulled from the outer periphery of the second winding barrel portion 22 into the outer periphery of the first winding barrel portion 21 through the first notch 241 to increase the length through the combination of the first line segment 51, the second line segment 52 and the growth segment 531.

[0075] Specifically, the elastic positioning member 6 includes an elastic seat 61 and a positioning insert 62. The elastic seat 61 includes a connecting portion 611, a deformation portion 612 arranged at both ends of the connecting portion 611, and an assembly portion 613 arranged at one end of each deformation portion 612 away from the connecting portion 611. The deformation portion 612 is wavy from one end of the connecting portion 611 to one end of the assembly portion 613. The assembly portion 613 is fixed to the winding reel 2 by welding or bolting. The positioning insert 62 is welded to the connecting portion 611, and the positioning insert 62 is extended backward and inserted between the two adjacent growth sections 531.

[0076] Among them, when the traction force applied to the first line segment 51 is greater than a certain size, under the action of force transmission, the force applied by the second turning segment 532 on the positioning plug 62 can drive the positioning plug 62 to move. The positioning plug 62 slides forward under the action of the force and finally, when the movement trajectories of the positioning plug 62 and the second turning segment 532 are misaligned, the movement restriction of the second turning segment 532 is completely released, and the second turning segment 532 can pass over the positioning plug 62. Thereafter, the traction force will drive the two growth segments 531 corresponding to the second turning segment 532 with the movement restriction released to extend from the second notch 251. In addition, during the process of the positioning plug 62 being pushed forward, the deformation portion 612 will adapt to the deformation to accumulate elastic potential energy, and after the second turning section 532 completely passes over the positioning plug 62, the deformation portion 612 will reset to allow the positioning plug 62 to return to the movement trajectory of the second turning section 532. When the third line segment 53 is subsequently rearranged, the second turning section 532 needs to reversely pass over the positioning plug 62 and be restricted in movement again.

[0077] Specifically, the winding drum 2 is provided with a mounting plate 26 at the front end of the third winding drum portion 23. An elastic seat 61 is provided in front of the mounting plate 26. The mounting plate 26 is provided with guide slots 261 extending from front to back for the positioning inserts 62 to pass through. The second partition plate 25 and the mounting plate 26 can clamp and position the third wire segment 53, ensuring that the extended segment 531 is stably arranged along the radial direction of the winding drum 2.

[0078] Preferably, guide bevels 621 are respectively provided on both sides of the rear end of the positioning insert 62 so that the second turning section 532 acts on the guide bevels 621 in a positive or negative direction to push the positioning insert 62 forward.

[0079] Preferably, one end of one of the growth segments 531 is connected to the winding reel 2, and one end of one of the growth segments 531 is connected to the adaptation segment 523. The growth segment 531 connected to the winding reel 2 is located on the radial inner side of each growth segment 531 along the winding reel 2, and the growth segment 531 connected to the adaptation segment 523 is located on the radial outer side of each growth segment 531 along the winding reel 2.

[0080] Therefore, under the action of the traction force, the growth segments 531 are sequentially pulled in the radially inward direction, so that the subsequent rearrangement of the third line segments 53 from the inside to the outside is smoother.

[0081] In addition, combined Figure 9 、 Figure 10As shown, the inner circumference of the winding reel 2 in this embodiment is provided with a built-in cavity 27; the driving device 3 includes a rotating motor 31 and a reduction mechanism 32, the rotating motor 31 is fixed to the frame 1 by means of bolts or the like, and is located at the rear end of the winding reel 2, and the reduction mechanism 32 is arranged in the built-in cavity 27; the rotating motor 31 is used to drive the reduction mechanism 32 to work so that the winding reel 2 is rotated through the reduction mechanism 32.

[0082] Therefore, the deceleration mechanism 32 is provided by providing the built-in cavity 27 on the inner periphery of the winding drum 2, so that the overall structure is more compact.

[0083] Specifically, the reduction mechanism 32 includes a reduction housing 321, an input shaft 322, a first-stage planetary carrier 323, and an output shaft 324.

[0084] Therefore, the speed reduction mechanism 32 is driven to rotate through the input portion 3221 to drive the input shaft 322 to rotate, and with the cooperation of the primary planetary structure and the secondary planetary structure, the output shaft 324 is reduced in speed, thereby driving the winding reel 2 to rotate.

[0085] Among them, a first bearing 71 is provided at the outer periphery of the input part 3221, and a second bearing 72 is provided at the middle of the length of the input shaft 322.

[0087] The driving device 3 includes a worm gear reduction box disposed between the rotating motor 31 and the reduction mechanism 32, or the rotating motor 31 is a worm gear reduction motor. This allows the rotating motor 31 to drive the winding drum 2 to rotate when the rotating motor 31 is in operation, while the winding drum 2 cannot rotate automatically when the rotating motor 31 is not in operation, thereby improving safety.

[0088] The rotating motor 31 is a servo motor for precise rotation control.

[0089] In addition, combined Figure 11 、 Figure 12As shown, a first inner ring tooth portion 81 is integrally formed on the inner circumferential wall of the assembly cavity 3211, and a first outer ring tooth portion 82 is integrally formed on the outer circumferential wall of the input shaft 322.

The first plates 91 and the second plates 92 are arranged at intervals. Each of the first plates 91 and the second plates 92 is annular and is arranged between the first inner ring tooth portion 81 and the first outer ring tooth portion 82. The outer circumference of each first plate 91 is integrally formed with a second outer ring tooth portion 911 that is clamped to the first inner ring tooth portion 81, and the inner circumference of each second plate 92 is integrally formed with a second inner ring tooth portion 921 that is clamped to the first outer ring tooth portion 82. The piston 102 is located behind the brake pad group 9. The piston 102 is slidably arranged in the assembly cavity 3211 along the front and rear directions by cooperating with the inner peripheral wall of the assembly cavity 3211. The brake spring 101 is compressed and arranged between the piston 102 and the reduction housing 321 to push the piston 102 forward, so that the piston 102 is pressed on the brake pad group 9 and limits the rotation of the input shaft 322. In addition, a boosting area 103 is provided between the piston 102 and the reduction housing 321, and a pressure inlet channel 104 is provided on the outer peripheral wall of the reduction housing 321, which passes through and connects to the boosting area 103, so that the boosting area 103 can be pressurized by connecting a pressure cylinder or an air pressure source or a hydraulic source before the rotating motor 31 works to release the pressure of the piston 102 on the brake pad group 9, so that the input shaft 322 rotates more smoothly.

[0090] Specifically, the brake pad group 9, the brake spring 101 and the piston member 102 are all arranged between the first bearing 71 and the second bearing 72, wherein the number of first plates 91 is one more than the number of second plates 92, the rearmost first plate 91 and the piston member 102 are offset against each other, and the frontmost first plate 91 and the reduction housing 321 are offset against each other.

[0091] A certain distance is maintained between the inner periphery of the first plate 91 and the first outer ring tooth portion 82, and a certain distance is maintained between the outer periphery of the second plate 92 and the first inner ring tooth portion 81. Furthermore, a plurality of first oil grooves 912 and a plurality of second oil grooves 913 are respectively provided on the front and rear surfaces of each first plate 91. Each first oil groove 912 is an annular groove and is arranged radially along the first plate 91. Each second oil groove 913 is arranged at intervals along the circumference of the first plate 91 and extends radially through the first plate 91.

[0092] Therefore, the lubricating oil entering from the oil injection channel 3214 flows through the second bearing 72 under the action of injection pressure and continues to flow backward to the brake pad group 9, and lubrication of each first plate 91 and second plate 92 is achieved under the conduction of the second oil groove 913, the distance between the inner periphery of the first plate 91 and the first outer ring tooth portion 82, and the distance between the outer periphery of the second plate 92 and the first inner ring tooth portion 81, ensuring the smooth sliding of the first plate 91 relative to the first inner ring tooth portion 81 and the smooth sliding of the second plate 92 relative to the first outer ring tooth portion 82, and then the lubricating oil continues to flow backward to lubricate the first bearing 71, wherein the setting of the first oil groove 912 makes it possible to evenly guide the lubricating oil to each second oil groove 913, so that each second oil groove 913 can distribute the lubricating oil more evenly circumferentially on the first inner ring tooth portion 81.
