Referring to fig. 3, the operation principle of the rope guiding device 100 provided in this embodiment is as follows:

the platform 4 can be arranged behind or in front of the base 1 in the cable entry direction X, in the present embodiment, it is explained that the platform 4 is arranged behind the base 1 in the cable entry direction X:

the cable 10 comprises a guide rope part 101 and a cable part 102 connected with the guide rope part 101, the diameter of the guide rope part 101 is smaller, the gravity is lighter, the guide rope part 101 is firstly pulled to the cable guide device 100, then the cable part 102 is gradually pulled to the cable guide device 100, and the resistance generated by the sagging of the cable 10 when the cable 10 is guided by the onshore sailor in the early stage is reduced;

a sailor on the bank puts a guide rope thrown by a shipman on a ship in a bracket 50 of a riding wheel 21, then connects a pressing wheel 31 with the riding wheel 21, a pressing groove 40 of the pressing wheel 31 presses on a guide rope part 101, at the moment, the guide rope part 101 penetrates through a first space formed by the bracket 50 and the pressing groove 40 and is limited by the groove wall of the bracket 50 and the groove wall of the pressing groove 40 to move up and down, and simultaneously, as the riding wheel 21 is rotationally arranged on a riding wheel shaft 2, the pressing wheel 31 is also rotationally arranged on a pressing wheel shaft 3, so that the guide rope part 101 can only move along a cable inlet direction X or a cable outlet direction Y relative to the first space;

after the guide rope portion 101 passes through the first space, the guide rope portion 101 is placed between the first clamping wheel 41 and the second clamping wheel 42, that is, the guide rope portion 101 is limited by the first clamping wheel 41 and the second clamping wheel 42 and can only move along the cable feeding direction X relative to the second space;

the ashore sailor starts to pull the guide rope part 101 towards the ashore direction, namely the guide rope part 101 moves along the direction X of the cable entry, until the head of the cable 10 between the guide rope part 101 and the cable part 102 moves to the front of the first space, because the diameters of the head of the cable 10 and the cable part 102 are larger, the pinch roller 31 is opened at the moment, the pinch roller 31 is not connected with the riding wheel 21 any more, the head of the cable 10 and the cable part 102 can sequentially pass through the first space and the second space, the pinch roller 31 is connected with the riding wheel 21 again, and the pinch roller is pressed on the cable part 102;

the onshore sailor pulls the cable part 102 again, the pulling length is as long as the position of the cable part 102 which can be sleeved into the onshore bollard, and the first clamping wheel 41 and the second clamping wheel 42 are used for clamping and fixing the cable part 102, so that when the cable part 102 moves along the cable withdrawing direction Y, the first clamping wheel 41 and the second clamping wheel 42 are driven to move, the distance between the first clamping wheel 41 and the second clamping wheel 42 is narrowed, the cable part 102 is clamped, the cable part 102 can only move along the cable inlet direction X and can not move along the cable withdrawing direction Y, at the moment, the onshore sailor can not withdraw the cable towards the ship even if the cable part 102 is released, namely, the cable part 102 is not stressed, and the onshore sailor can be sleeved into the bollard very conveniently and easily;

the mooring rope part 102 is withdrawn from the first space and the second space after the mooring rope is finished, and the mooring work is finished; specifically, cable portion 102 exits from between first pinch wheel 41 and second pinch wheel 42, at the same time pinch wheel 31 is opened, such that cable portion 102 exits from between idler 21 and pinch wheel 31, and cable portion 102 moves out of cable guide 100.

By adopting the technical scheme:

firstly, when the cable 10 is guided, the cable 10 moves between the pressing wheel 31 and the supporting wheel 21 along the cable feeding direction X, and the pressing wheel 31 and the supporting wheel 21 are both rotationally arranged, so that the rotating friction is generated when the cable 10 is fed, and the resistance generated in the cable feeding process of the cable 10 is reduced;

secondly, a second space for the cable 10 to pass through is formed between the first clamping wheel 41 and the second clamping wheel 42, and the second space can be narrowed when the cable 10 moves in the cable withdrawing direction Y, so that the cable 10 is clamped, the cable 10 can only move in the cable feeding direction X and cannot be withdrawn, a shore water hand can conveniently sleeve the cable 10 with a proper length after pulling out the cable 10, and meanwhile, the cable 10 is withdrawn due to uneven force applied by a plurality of shore water hands, the cable 10 is prevented from being dragged down or dragged to the sea due to the counter force of the cable 10, so that safety accidents are caused, and potential safety hazards are caused;

finally, the pressure roller 31 can be opened relative to the idler 21, so that different sizes of the guide rope portion 101 and the rope portion 102 of the rope 10 can enter the first space between the pressure roller 31 and the idler 21 at different time periods of the rope feeding, and the applicability of the rope guiding device 100 is improved.

In one embodiment, the bracket 50 of idler 21 and the indent 40 of pressure wheel 31 are both "U" shaped slots, and the width of indent 40 is less than the width of bracket 50.

Specifically, the bracket 50 interfaces with the crush slots 40 to form a space around the cable 10.

By adopting the technical scheme, the shapes of the bracket 50 and the pressing groove 40 are adapted to the shape of the cable 10, so that the space formed by the bracket 50 and the pressing groove can ensure that the cable 10 is relatively fixed in position.
