Description

Technical Field

[0001] The utility model relates to the technical field of ship shore power winches, in particular to a two-way wire-releasing device for a ship shore power winch. Background Art

[0002] Ship shore power winch, also known as ship shore power cable winch, is a ship deck equipment, mainly used to connect the ship with the shore power supply to provide power to the ship. Specifically, it is an interconnection device for the ship to receive high-voltage power supply, optical fiber cable and control cable from the shore. The ship shore power winch is usually driven by a motor, fixed on the ship, and can be used for a variety of purposes, such as anchoring, mooring, towing and lifting cargo. When the ship arrives at the port or dock, the ship shore power winch can help with anchoring and mooring, ensuring that the ship stops and stays safely in place without moving or drifting.

[0003] However, when the prior art is actually used, during the process of using a ship shore power winch to pay out the cable in both directions, the usual ship shore power winch uses a fixed barrier rod to block and limit the bidirectionally paid-out cable so as to maintain the stable bidirectional retraction and extension of the cable. However, when the bidirectionally paid-out cable is blocked and limited by the fixed barrier rod, the barrier rod is not convenient to adjust according to the degree of cable retraction and extension and the distance between the cables, thereby affecting the stability of the cable during bidirectional retraction and extension. Utility Model Content

[0004] The utility model aims to provide a two-way pay-out device for a ship shore power winch, so as to solve the problem proposed in the above background technology that in the process of using a ship shore power winch to pay out the cable in both directions, the conventional ship shore power winch blocks and limits the two-way pay-out cable by a fixed baffle bar so as to maintain the stable two-way retraction and release of the cable. However, when the two-way pay-out cable is blocked and limited by the fixed baffle bar, the baffle bar is not convenient to be adjusted according to the degree of cable retraction and release and the distance between the cables, thereby affecting the stability of the cable during two-way retraction and release.

[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: comprising a mounting base plate, a motor is fixedly mounted on the side end of the upper surface of the mounting base plate, a first pulley is fixedly mounted on the transmission shaft at the front end of the motor, the outer end of the first pulley is connected to the second pulley through a transmission belt, the middle part of the second pulley is connected to the retractable shaft through a reducer, a retractable wheel is fixedly mounted on the outer curved surface of the middle part of the retractable shaft, and a ship shore power cable is wound around the middle part of the retractable wheel;

[0006] A front support frame is fixedly installed on the front side of the upper end of the mounting base plate, and limited straight sliding grooves are provided on both sides of the inner end of the front support frame. A first limited sliding rod is fixedly installed on the inner wall of the limited straight sliding groove, and the outer curved surface in the middle of the first limited sliding rod is movably connected to the limited sliding block. A supporting spring is fixedly installed on the outer end of the limited sliding block, and a second limited sliding rod is fixedly installed on the side end of the limited sliding block, and the outer curved surfaces on both sides of the middle of the second limited sliding rod are movably connected to guide wheels;

[0007] A rear support frame is fixedly installed on the rear side of the upper end of the mounting base plate, an extension frame is fixedly installed on the rear side of the upper end of the rear support frame, the lower end of the extension frame is rotatably connected to a swing arm via a pin shaft, the upper end of the extension frame is rotatably connected to an electric telescopic rod via a pin shaft, and a limit stop rod for blocking the ship shore power cable is fixedly installed on the front end of the swing arm.

[0008] Preferably, fixing holes are formed through the four corners of the installation base plate, and there are four fixing holes, which are symmetrically distributed at the four corners of the installation base plate.

[0009] Preferably, the retractable shaft is rotatably connected to the upper end of the mounting base plate through a bearing seat support, and there are two retractable wheels, which are symmetrically distributed on the outer curved surface in the middle of the retractable shaft.

[0010] Preferably, there are two limiting straight sliding grooves, which are symmetrically distributed on both sides of the inner end of the front support frame, and the limiting sliding blocks are symmetrically distributed up and down on the outer curved surface in the middle part of the first limiting sliding rod.

[0011] Preferably, the support spring is fixedly installed on the inner wall of the limiting straight sliding groove at one end away from the limiting sliding block, and the guide wheel is located at the front end of the retracting and releasing wheel.

[0012] Preferably, the telescopic portion at the lower end of the electric telescopic rod is rotatably connected to the rear end of the swing arm via a pin.

[0013] Compared with the prior art, the beneficial effects of the utility model are:

[0014] 1. When the guide wheel guides the retraction and release of the ship shore power cable, the ship shore power cable will push the guide wheel up and down according to the retraction and release angle. When the ship shore power cable pushes the guide wheel up and down, the guide wheel will drive the second limit slide bar to move up and down. When the second limit slide bar moves up and down, it will drive the limit slide bar to move up and down along the outer curved surface of the first limit slide bar. When the limit slide bar moves up and down along the outer curved surface of the first limit slide bar, it will push the compression or extension support spring. When the support spring is pushed to be compressed or stretched, the elastic potential energy generated by the deformation of the support spring itself will push the limit slide bar in the opposite direction, so that the limit slide bar will drive the guide wheel to always fit with the ship shore power cable, thereby realizing the two-way line release guidance of the ship shore power cable, and at the same time, the ship shore power cable can be buffered and fitted to the guide, so as to avoid the situation where the retraction and release angle of the ship shore power cable is too large, resulting in an increase in the friction between the guide wheel and the ship shore power cable, which affects the line release;

[0015] 2. The utility model also controls the opening of the electric telescopic rod when the ship shore power cable is being retracted and released. When the electric telescopic rod is turned on, it will push the rear end of the swing arm to swing up and down. When the rear end of the swing arm swings up and down, it will drive the limit stopper to swing up and down. When the limit stopper swings up and down, the distance between the limit stopper and the ship shore power cable can be adjusted, so that during the retraction and release of the ship shore power cable, the limit stopper always maintains the same blocking distance as the ship shore power cable, thereby ensuring the stable retraction and release of the ship shore power cable.

[0022] A front support frame 20 is fixedly installed on the front side of the upper end of the installation base plate 1, and limited straight sliding grooves 9 are provided on both sides of the inner end of the front support frame 20, and there are two limited straight sliding grooves 9, which are symmetrically distributed on both sides of the inner end of the front support frame 20, and a first limited sliding rod 10 is fixedly installed on the inner wall of the limited straight sliding groove 9, and the outer curved surface of the middle part of the first limited sliding rod 10 is movably connected to the limited sliding block 11, and the limited sliding block 11 is symmetrically distributed up and down with the outer curved surface of the middle part of the first limited sliding rod 10, and the outer end of the limited sliding block 11 is fixedly installed with a supporting spring 12, and the supporting spring 12 is fixedly installed on the inner wall of the limited straight sliding groove 9 away from one side end of the limited sliding block 11, so that the supporting spring 12 cooperates with the first limited sliding rod 10 to elastically support the limited sliding block 11, and a second limited sliding rod 13 is fixedly installed on the side end of the limited sliding block 11, and the outer curved surfaces on both sides of the middle part of the second limited sliding rod 13 are movably connected with guide wheels 14, and the guide wheels 14 are located at the front end of the retracting and releasing wheel 7;

[0023] A rear support frame 15 is fixedly installed on the rear side of the upper end of the installation base plate 1, an extension frame 16 is fixedly installed on the rear side of the upper end of the rear support frame 15, the lower end of the extension frame 16 is rotatably connected to a swing arm 17 through a pin shaft, the upper end of the extension frame 16 is rotatably connected to an electric telescopic rod 18 through a pin shaft, the telescopic part of the lower bottom end of the electric telescopic rod 18 is rotatably connected to the rear end of the swing arm 17 through a pin shaft, and a limit stopper rod 19 for blocking the ship shore power cable 8 is fixedly installed at the front end of the swing arm 17.

[0024] Working principle: When in use, the utility model passes the shore power cable 8 through the inner side of the guide wheel 14. When the shore power cable 8 passes through the inner side of the guide wheel 14, the motor 3 is turned on by control. When the motor 3 is turned on, the first pulley 4 is driven to rotate. When the first pulley 4 rotates, the second pulley 5 is driven to rotate through the transmission belt. When the second pulley 5 rotates, the retracting shaft 6 is driven to rotate through the speed reducer. When the retracting shaft 6 rotates, the retracting wheel 7 is driven to rotate. When the retracting wheel 7 rotates, the shore power cable 8 is driven to rotate and retract. When the shore power cable 8 rotates and retracts, the shore power cable 8 is guided to be retracted and released through the guide wheel 14. When the guide wheel 14 guides the shore power cable 8 to be retracted and released, the shore power cable 8 pushes the guide wheel 14 up and down according to the retracting angle. When the ship shore power cable 8 pushes the guide wheel 14 up and down, the guide wheel 14 will drive the second limit slide bar 13 to move up and down. When the second limit slide bar 13 moves up and down, it will drive the limit slide bar 11 to move up and down along the outer curved surface of the first limit slide bar 10. When the limit slide bar 11 moves up and down along the outer curved surface of the first limit slide bar 10, it will push the compression or extension support spring 12. When the support spring 12 is pushed to be compressed or stretched, the elastic potential energy generated by the deformation of the support spring 12 itself will push the limit slide bar 11 in the opposite direction, so that the limit slide bar 11 will drive the guide wheel 14 to always fit with the ship shore power cable 8, thereby realizing the two-way line-release guiding of the ship shore power cable 8, and at the same time, the guide buffer fitting of the ship shore power cable 8 can be achieved, so as to avoid the situation where the retraction and release angle of the ship shore power cable 8 is too large, resulting in the increase of friction between the guide wheel 14 and the ship shore power cable 8, which affects the line release;

[0025] At the same time, when the ship shore power cable 8 is retracted and released, the electric telescopic rod 18 is turned on by control. When the electric telescopic rod 18 is turned on, it will push the rear end 17 of the swing arm to swing up and down. When the rear end of the swing arm 17 swings up and down, it will drive the limit stop rod 19 to swing up and down. When the limit stop rod 19 swings up and down, the distance between the limit stop rod 19 and the ship shore power cable 8 can be adjusted, so that during the retraction and release of the ship shore power cable 8, the limit stop rod 19 always maintains the same blocking distance as the ship shore power cable 8, thereby ensuring the stable retraction and release of the ship shore power cable 8.
