Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of wharf cable towing, and more particularly to a cable guiding device. BACKGROUND

[0002] When a thousand-ton class ship such as a cargo ship needs to be berthed at a sea port, in order to avoid the impact of the cargo ship on the wharf wall, a thinner guide rope is thrown from the ship to the shore by the crew on the ship when the cargo ship is at a distance of 2-30 m from the shore. The guide rope is connected to the cable head, and 3-10 sailors on the shore pull the cable from the water surface to the wharf, and then the cable sleeve is sleeved on the bollard to complete the pre-berthing towing work. Then the cargo ship is stably berthed in place through the retraction and extension of the front and rear cables. According to the size of the cargo ship, there are usually 4 groups of cables, including 1-2 cables, with a diameter of about 60-120 mm, at the bow and stern.

[0003] Since the cable is soaked in seawater, it is very heavy, and it is a whole "U" structure from the shore to the water surface, and then to the cargo ship. The cable needs to overcome the weight of the cable and the coordination of multiple people. Since the distance from the water surface to the ground height of the wharf is affected by the tide, the range is 2-15 m, and the sailors pull the cable to the top of the wharf wall. The frictional resistance between the cable and the wharf wall is large, and it is very difficult to pull the cable. If the force is uneven or the number of people is insufficient among the several sailors, it is easy to be pulled down by the counterforce of the cable or dragged into the sea, causing safety accidents and a great safety hazard. Therefore, there are technical problems of large resistance and easy injury of the operator in the process of guiding the cable when the ship is berthed. SUMMARY

[0004] The purpose of the present application is to provide a cable guiding device to solve the technical problems of large resistance and easy injury of the operator in the process of guiding the cable when the ship is berthed in the prior art.

[0005] To achieve the above-mentioned purpose, the technical solution adopted by the present application is a cable guiding device, comprising:

[0006] A base is used to be fixed on the wharf, and the base is provided with opposite first and second supports;

[0007] A roller shaft is arranged between the first and second supports, and a roller is rotatably arranged on the roller shaft;

[0008] A pressure roller shaft is arranged between the first and second supports, and a pressure roller is rotatably arranged on the pressure roller shaft. The pressure roller can be connected to the roller, so that the pressure groove on the outer periphery of the pressure roller and the roller groove on the outer periphery of the roller form a first space for the cable to pass through;

[0009] a platform arranged adjacent to the base in the cable-in direction of the cable, the platform oppositely provided with a first clamping wheel and a second clamping wheel, a second space formed between the first clamping wheel and the second clamping wheel for the cable to pass through, the second space capable of being narrowed when the cable moves in the cable-out direction.

[0010] By adopting the technical scheme described above,

[0011] Firstly, when guiding the cable, the cable moves in the cable-in direction X between the compression wheel and the supporting wheel, and both the compression wheel and the supporting wheel are rotationally arranged, so that rotational friction occurs when the cable is fed in, thereby reducing the resistance generated in the process of feeding in the cable;

[0012] Secondly, a second space is formed between the first clamping wheel and the second clamping wheel for the cable to pass through, and the second space can be narrowed when the cable moves in the cable-out direction Y, thereby clamping the cable, so that the cable can only move in the cable-in direction X and cannot move out, which facilitates the sailors on the shore to set the appropriate length of the cable on the mooring post after pulling, and also avoids uneven force of multiple sailors on the shore, which causes the cable to move out, and the counterforce of the cable drags the personnel to the sea, causing safety accidents and safety hazards;

[0013] Finally, the compression wheel can be opened relative to the supporting wheel, so that the different sizes of the guide rope part and the cable part of the cable can enter the first space between the compression wheel and the supporting wheel at different time periods of feeding in, thereby improving the applicability of the cable guiding device.

[0014] In an embodiment, the platform is provided with a first sliding plate and a second sliding plate, the first sliding plate is provided with a first guide groove, the second sliding plate is provided with a second guide groove, the distance between the first guide groove and the second guide groove gradually decreases along the cable-out direction of the cable, the first clamping wheel can slide along the length direction of the first guide groove, and the second clamping wheel can slide along the length direction of the second guide groove.

[0015] By adopting the technical scheme described above, the cable drives the first clamping wheel and the second clamping wheel to move in the cable-in direction X or the cable-out direction Y, so as to adjust the size of the second space, thereby making the cable unable to move out and only move in the cable-in direction X in one direction, saving the pulling strength required by the sailors on the shore, facilitating the mooring operation of the sailors on the shore, and improving the safety of feeding in the cable.

[0016] In an embodiment, the first guide groove is provided with a first elastic member for driving the first clamping wheel to move in the cable-out direction, and the second guide groove is provided with a second elastic member for driving the second clamping wheel to move in the cable-out direction.

[0017] By adopting the technical scheme, the first elastic member and the second elastic member enable the first clamping wheel and the second clamping wheel to always maintain a state of clamping the cable, thereby preventing the cable from falling off the first clamping wheel and the second clamping wheel, and further improving the safety performance.

[0018] In one embodiment, the first sliding plate is rotationally connected with the first clamping wheel, and a first one-way structure is arranged between the first sliding plate and the first clamping wheel to enable the first clamping wheel to rotate in one direction; the second sliding plate is rotationally connected with the second clamping wheel, and a second one-way structure is arranged between the second sliding plate and the second clamping wheel to enable the second clamping wheel to rotate in one direction.

[0019] By adopting the technical scheme, the first one-way structure and the second one-way structure respectively control the first clamping wheel and the second clamping wheel to rotate in one direction, so that when the cable moves between the first clamping wheel and the second clamping wheel, the cable can only move in the cable-in direction X, and when the cable moves in the cable-out direction Y, the first clamping wheel and the second clamping wheel stop rotating, so that the cable drives the first clamping wheel and the second clamping wheel to move, thereby narrowing the distance between the two, and further fixing the cable to prevent the cable from being taken out.

[0020] In one embodiment, the platform further comprises a sliding block guide rail, the first sliding plate is provided with a first sliding block that is slidingly connected with the sliding block guide rail, the second sliding plate is provided with a second sliding block that is slidingly connected with the sliding block guide rail, and the first sliding block and the second sliding block can move along the length direction of the sliding block guide rail to adjust the width of the second space.

[0021] By adopting the technical scheme, the size of the second space between the first clamping wheel and the second clamping wheel is adjustable, which can be adjusted according to the diameter of the cable to be guided, and the adjustment flexibility is high.

[0022] In one embodiment, the pressure wheel shaft is located above the supporting wheel shaft, one end of the pressure wheel shaft is rotationally connected with the second support, and the other end of the pressure wheel shaft can be lockingly connected with the first support.

[0023] By adopting the technical scheme, it is convenient for the sailor on the shore to open and close the pressure wheel shaft, and the cable can be conveniently guided into the space between the pressure wheel and the supporting wheel.

[0024] In one embodiment, the other end of the pressure wheel shaft is provided with a hook plate and a hook plate elastic member that connects the hook plate and the pressure wheel shaft, the first support is provided with a hook table corresponding to the hook plate, and the hook plate elastic member drives the hook plate to rotate to maintain a state of being lockingly connected with the hook table.

[0025] By adopting the technical scheme, the stability when the pressure wheel and the supporting wheel are connected is improved.

[0026] In one embodiment, the supporting wheel and the pressing wheel are arranged in a first direction, the first clamping wheel and the second clamping wheel are arranged in a second direction, the first direction is perpendicular to the second direction, and the first direction and the second direction are both perpendicular to the cable entering direction.

[0027] By adopting the above technical solution, the movement of the cable is controlled in two perpendicular directions, the movement of the cable in the first direction and the second direction is limited, and the cable can only move along the cable entering direction X, so that the stability of the cable movement is further improved.

[0028] In one embodiment, the bottom of the base extends downwardly with a plurality of clamping claws, and the plurality of clamping claws enclose a clamping opening for clamping the wheel protection trench of the wharf.

[0029] By adopting the above technical solution, the base can be clamped on the wheel protection trench, and the convenience of installation of the cable guiding device is improved.

[0050] As shown in Figure 1 and Figure 2 , the cable guide device 100 provided by the embodiment of the present application is used to guide the cable 10 of the ship.

[0051] The cable guide device 100 of the embodiment includes a base 1, a carrier wheel shaft 2, a pressure wheel shaft 3 and a platform 4; the base 1 is used to be fixed on the wharf 20, the fixing mode of the base 1 includes but is not limited to clamping or fastening connection, the base 1 is located at the edge of the wharf 20 close to the sea surface, the base 1 is provided with opposite first and second supports 11 and 12; the carrier wheel shaft 2 is arranged between the first and second supports 11 and 12, and the carrier wheel 21 is rotatably arranged on the carrier wheel shaft 2; the pressure wheel shaft 3 is arranged between the first and second supports 11 and 12, and the pressure wheel 31 is rotatably arranged on the pressure wheel shaft 3, the pressure wheel 31 can be butted with the carrier wheel 21, so that the pressure groove 40 on the outer periphery of the pressure wheel 31 and the carrier groove 50 on the outer periphery of the carrier wheel 21 form a first space for the cable 10 to pass through, the pressure groove 40 and the carrier groove 50 are both "U" grooves, the groove openings of the pressure groove 40 and the carrier groove 50 are oppositely arranged, and the first space is formed by the two oppositely or enclosing, the cable 10 passes through the first space, the pressure groove 40 and the carrier groove 50 limit the cable 10 in the first space, and since the pressure wheel 31 and the carrier wheel 21 can both rotate, the cable 10 can move in the in-cable direction or the out-cable direction relative to the first space; the platform 4 is arranged adjacent to the base 1 in the in-cable direction X of the cable 10, and the first and second clamping wheels 41 and 42 are oppositely arranged on the platform 4, and the second space for the cable 10 to pass through is formed between the first and second clamping wheels 41 and 42, and the second space can be narrowed when the cable 10 moves in the out-cable direction Y.

[0052] Please see Figure 3 , the action principle of the cable guide device 100 provided by the embodiment is as follows:

[0053] The platform 4 can be arranged after or before the base 1 in the cable entering direction X, and in this embodiment, the arrangement of the platform 4 after the base 1 in the cable entering direction X is described:

[0054] The cable 10 includes a guide rope portion 101 and a cable portion 102 connected with the guide rope portion 101, the diameter of the guide rope portion 101 is smaller and the gravity is lighter, the guide rope portion 101 is first pulled to the cable guiding device 100, and then the cable portion 102 is gradually pulled to the cable guiding device 100, so as to reduce the resistance generated by the sag of the cable 10 when the sailor on the shore guides the cable 10 in the early stage;

[0055] The sailor on the shore places the guide rope thrown by the crew on the ship in the supporting groove 50 of the supporting wheel 21, and then the pressing wheel 31 is connected with the supporting wheel 21, the pressing groove 40 of the pressing wheel 31 is pressed on the guide rope portion 101, at this time, the guide rope portion 101 passes through the first space formed by the supporting groove 50 and the pressing groove 40, and is simultaneously limited to move up and down by the groove walls of the supporting groove 50 and the pressing groove 40, and at the same time, the supporting wheel 21 is arranged to rotate on the supporting shaft 2, and the pressing wheel 31 is arranged to rotate on the pressing shaft 3, so that the guide rope portion 101 can only move along the cable entering direction X or the cable withdrawing direction Y relative to the first space;

[0056] 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 entering direction X relative to the second space;

[0057] The sailor on the shore starts to pull the guide rope portion 101 towards the shore direction, that is, the guide rope portion 101 moves along the cable entering direction X, until the head of the cable 10 between the guide rope portion 101 and the cable portion 102 moves to the front of the first space, because the diameter of the head of the cable 10 and the cable portion 102 is larger, at this time, the pressing wheel 31 is opened, so that the pressing wheel 31 is no longer connected with the supporting wheel 21, so that the head of the cable 10 and the cable portion 102 can pass through the first space and the second space in turn, and the pressing wheel 31 is connected with the supporting wheel 21 again and pressed on the cable portion 102;

[0058] The sailor on the shore pulls the cable portion 102 again, and the length of the pulling is stopped according to the position of the mooring bitt on the shore, because the first clamping wheel 41 and the second clamping wheel 42 have the function of clamping and fixing the cable portion 102, so that when the cable portion 102 moves along the cable withdrawing direction Y, the first clamping wheel 41 and the second clamping wheel 42 are driven to move, so that the distance between the two is narrowed to clamp the cable portion 102, so that the cable portion 102 can only move along the cable entering direction X and cannot move along the cable withdrawing direction Y, at this time, even if the sailor on the shore releases the cable portion 102, the cable portion 102 will not move towards the ship, that is, the cable portion 102 is not under stress, and can be very conveniently and easily inserted into the mooring bitt;

[0059] The cable part 102 after the mooring is completed exits from the first space and the second space, and the mooring work is completed; specifically, the cable part 102 exits from between the first clamping wheel 41 and the second clamping wheel 42, and the compression wheel 31 is opened at the same time, so that the cable part 102 exits from between the supporting wheel 21 and the compression wheel 31, and the cable part 102 moves out of the cable guiding device 100.

[0060] By adopting the technical scheme described above:

[0061] Firstly, when guiding the cable 10, the cable 10 moves in the cable-in direction X between the compression wheel 31 and the supporting wheel 21, and the compression wheel 31 and the supporting wheel 21 are both rotationally arranged, so that the cable 10 generates rotational friction when the cable 10 is in, which reduces the resistance generated by the cable 10 in the process of in.

[0062] Secondly, the first clamping wheel 41 and the second clamping wheel 42 form a second space for the cable 10 to pass through, and the second space can be narrowed when the cable 10 moves in the cable-out direction Y, thereby clamping the cable 10, so that the cable 10 can only move in the cable-in direction X and cannot be out, which facilitates the sailors on the shore to set the appropriate length of the cable 10 on the mooring post, and also avoids the uneven force of multiple sailors on the shore causing the cable 10 to be out, and the reaction force of the cable 10 dragging the cable personnel down or to the sea, causing safety accidents and safety hazards;

[0063] Finally, the compression wheel 31 can be opened relative to the supporting wheel 21, so that the different sizes of the guiding rope part 101 and the cable part 102 of the cable 10 can enter the first space between the compression wheel 31 and the supporting wheel 21 at different time periods of in, thereby improving the applicability of the cable guiding device 100.

[0064] In an embodiment, the supporting groove 50 of the supporting wheel 21 and the compression groove 40 of the compression wheel 31 are both "U"-shaped grooves, and the width of the compression groove 40 is smaller than the width of the supporting groove 50.

[0065] Specifically, the supporting groove 50 and the compression groove 40 are connected to form a space surrounding the cable 10.

[0066] By adopting the technical scheme described above, the shapes of the supporting groove 50 and the compression groove 40 are adapted to the shape of the cable 10, so that the space surrounded by the two can relatively fix the position of the cable 10.

[0067] As Figure 4 and Figure 5As shown, in one embodiment, the platform 4 is provided with a first sliding plate 43 and a second sliding plate 44, the first sliding plate 43 is provided with a first guide groove 431, the second sliding plate 44 is provided with a second guide groove 441, the distance between the first guide groove 431 and the second guide groove 441 gradually decreases along the cable-off direction Y of the cable 10, the first clamping wheel 41 can slide along the length direction of the first guide groove 431, and the second clamping wheel 42 can slide along the length direction of the second guide groove 441.

[0068] Specifically, the first sliding plate 43 and the second sliding plate 44 are oppositely arranged on the platform 4, the first sliding plate 43 is provided with the first guide groove 431, the second sliding plate 44 is provided with the second guide groove 441, the first guide groove 431 and the second guide groove 441 are both straight grooves, the first guide groove 431 gradually deviates to one side, the second guide groove 441 gradually deviates to the other side, and the first guide groove 431 and the second guide groove 441 form a dovetail-shaped guide groove; the bottom of the first clamping wheel 41 is provided with a first clamping wheel guide rail 411 matched with the first guide groove 431, the bottom of the second clamping wheel 42 is provided with a second clamping wheel guide rail 421 matched with the second guide groove 441, and the two guide rails form an "eight-character shape".

[0069] When the onshore sailor pulls the cable 10 to move along the cable-in direction X, the cable 10 passes through the second space between the first clamping wheel 41 and the second clamping wheel 42, which can drive the first clamping wheel 41 and the second clamping wheel 42 to move along the cable-in direction X, i.e. the first clamping wheel 41 and the second clamping wheel 42 move towards the direction in which the distance between the first guide groove 431 and the second guide groove 441 increases, so that the second space between the first clamping wheel 41 and the second clamping wheel 42 increases, which is beneficial to the onshore sailor to pull the cable 10.

[0070] When the onshore sailor releases the cable 10, the cable 10 moves along the cable-off direction Y under the action of its own gravity, and the cable 10 drives the first clamping wheel 41 and the second clamping wheel 42 to move along the cable-off direction Y, i.e. the first clamping wheel 41 and the second clamping wheel 42 move towards the direction in which the distance between the first guide groove 431 and the second guide groove 441 decreases, so that the second space between the first clamping wheel 41 and the second clamping wheel 42 decreases, so that the cable 10 is clamped between the first clamping wheel 41 and the second clamping wheel 42, preventing the cable 10 from being cable-off.

[0071] By adopting the above technical scheme, the cable 10 drives the first clamping wheel 41 and the second clamping wheel 42 to move along the cable-in direction X or the cable-off direction Y to adjust the size of the second space, so that the cable 10 cannot be cable-off and can only move unidirectionally along the cable-in direction X, which saves the strength required by the onshore sailor to pull, is beneficial to the onshore sailor to perform mooring operation, and improves the safety of the cable-in.

[0072] As Figure 6As shown, in one embodiment, the first guide slot 431 is provided with the first elastic member 432 for driving the first clamping wheel 41 to move towards the cable releasing direction Y, and the second guide slot 441 is provided with the second elastic member 442 for driving the second clamping wheel 42 to move towards the cable releasing direction Y.

[0073] Specifically, the first elastic member 432 and the second elastic member 442 include but are not limited to compression springs.

[0074] When the shore hand pulls the cable 10 to move along the cable entering direction X, the cable 10 passes through the second space between the first clamping wheel 41 and the second clamping wheel 42, which can drive the first clamping wheel 41 and the second clamping wheel 42 to move along the cable entering direction X against the elastic force of the first elastic member 432 and the second elastic member 442 respectively, so that the second space between the first clamping wheel 41 and the second clamping wheel 42 becomes larger, and at the same time, the first clamping wheel 41 and the second clamping wheel 42 always maintain the state of clamping the cable 10 under the action of the elastic force, thereby limiting the movement direction of the cable 10.

[0075] When the shore hand releases the cable 10, the cable 10 moves along the cable releasing direction Y under the action of its own gravity, and the first clamping wheel 41 and the second clamping wheel 42 move along the cable releasing direction Y under the action of the first elastic member 432 and the second elastic member 442 respectively, that is, the first clamping wheel 41 and the second clamping wheel 42 move towards the direction in which the distance between the first guide slot 431 and the second guide slot 441 becomes smaller, so that the second space between the first clamping wheel 41 and the second clamping wheel 42 becomes smaller, so that the cable 10 is clamped between the first clamping wheel 41 and the second clamping wheel 42, preventing the cable 10 from being released.

[0076] By adopting the above technical scheme, the first elastic member 432 and the second elastic member 442 make the first clamping wheel 41 and the second clamping wheel 42 always maintain the state of clamping the cable 10, preventing the cable 10 from falling off the first clamping wheel 41 and the second clamping wheel 42, and further improving the safety performance.

[0077] In addition, the first elastic member 432 and the second elastic member 442 can always push the first clamping wheel 41 and the second clamping wheel 42 to move along the cable releasing direction Y, so that the second space always maintains the trend of becoming smaller in width, ensuring the reliability of preventing the cable 10 from being released.

[0078] In one embodiment, the first sliding plate 43 is rotationally connected with the first clamping wheel 41, and a first one-way structure 45 is arranged between the first sliding plate 43 and the first clamping wheel 41 for allowing the first clamping wheel 41 to rotate in one direction; the second sliding plate 44 is rotationally connected with the second clamping wheel 42, and a second one-way structure 46 is arranged between the second sliding plate 44 and the second clamping wheel 42 for allowing the second clamping wheel 42 to rotate in one direction.

[0079] Optionally, the first clamping wheel 41 is rotatably connected with the first sliding plate 43 through a bearing, the first one-way structure 45 comprises a ratchet slot and a ratchet, one of the ratchet slot and the ratchet is arranged on the first clamping wheel 41, and the other of the ratchet slot and the ratchet is arranged on the first sliding plate 43, the ratchet is used for clamping in the ratchet slot to stop rotation of the first clamping wheel 41, and the ratchet can control one-way rotation of the first clamping wheel 41; when the first clamping wheel 41 reversely rotates, the ratchet is clamped in the ratchet slot, so that the first clamping wheel 41 stops rotating; similarly, the second clamping wheel 42 is rotatably connected with the second sliding plate 44 through a bearing, the second one-way structure 46 comprises a ratchet slot and a ratchet, one of the ratchet slot and the ratchet is arranged on the second clamping wheel 42, and the other of the ratchet slot and the ratchet is arranged on the second sliding plate 44, the ratchet can control one-way rotation of the second clamping wheel 42; when the second clamping wheel 42 reversely rotates, the ratchet is clamped in the ratchet slot, so that the second clamping wheel 42 stops rotating.

[0080] By adopting the above technical scheme, the first one-way structure 45 and the second one-way structure 46 respectively control one-way rotation of the first clamping wheel 41 and the second clamping wheel 42, so that when the cable 10 moves between the first clamping wheel 41 and the second clamping wheel 42, the cable 10 can only move along the cable-in direction X, and when the cable 10 moves along the cable-out direction Y, the first clamping wheel 41 and the second clamping wheel 42 stop rotating, so that the cable 10 drives the first clamping wheel 41 and the second clamping wheel 42 to move, so that the distance between the first clamping wheel 41 and the second clamping wheel 42 becomes narrow, and then the cable 10 is fixed, and the cable-out of the cable 10 is prevented.

[0081] In one embodiment, the platform 4 is further provided with a sliding block guide rail 47, the first sliding plate 43 is provided with a first sliding block 433 which is slidably connected with the sliding block guide rail 47, the second sliding plate 44 is provided with a second sliding block 443 which is slidably connected with the sliding block guide rail 47, and the first sliding block 433 and the second sliding block 443 can move along the length direction of the sliding block guide rail 47 to adjust the size of the second space.

[0082] Please refer to Figure 5Specifically, the slide rail 47 includes but is not limited to a double-rotation screw rod, which includes a screw rod 471, a screw rod base 472, and a rocker 473. The screw rod base 472 is fixedly arranged on the platform 4, the screw rod 471 is rotatably arranged on the screw rod base 472, and the rocker 473 is connected with one end of the screw rod 471. The first slide block 433 and the second slide block 443 are arranged on the screw rod 471 and threadedly cooperate with the screw rod 471. The shorehand swings the rocker 473 to rotate the screw rod 471, and the rotation of the screw rod 471 drives the first slide block 433 and the second slide block 443 to move along the length direction of the screw rod 471. The screw rod 471 is a double-rotation screw rod, in which one of the first slide block 433 and the second slide block 443 is a left-handed thread, and the other is a right-handed thread. The moving directions of the first slide block 433 and the second slide block 443 are opposite, so that the design can be used to adjust the width between the first slide block 433 and the second slide block 443, and further adjust the distance between the first slide plate 43 and the second slide plate 44, thereby adjusting the distance between the first clamping wheel 41 and the second clamping wheel 42.

[0083] By adopting the above technical scheme, the size of the second space between the first clamping wheel 41 and the second clamping wheel 42 is adjustable, which can be adjusted according to the diameter of the cable 10 to be guided, and the flexibility of the adjustment is high.

[0084] In one embodiment, the pressure wheel shaft 3 is located above the carrier wheel shaft 2, one end of the pressure wheel shaft 3 is rotatably connected with the second support 12, and the other end of the pressure wheel shaft 3 can be lockingly connected with the first support 11.

[0085] Specifically, the pressure wheel shaft 3 and the carrier wheel shaft 2 are arranged in an up-down manner, and the pressure wheel shaft 3 is located above the carrier wheel shaft 2, that is, when the pressure wheel 31 is in contact with the carrier wheel 21, the pressure wheel 31 is located above the carrier wheel 21.

[0086] When the cable 10 is fed, the shorehand releases the lock connection between the pressure wheel shaft 3 and the first support 11, then drives the pressure wheel shaft 3 to open the pressure wheel 31, places the cable 10 on the carrier wheel 21, and finally closes the pressure wheel shaft 3 and lockingly connects it with the first support 11, so that the pressure wheel 31 and the carrier wheel 21 jointly clamp the cable 10.

[0087] By adopting the above technical scheme, the shorehand can conveniently open and close the pressure wheel shaft 3, and the cable 10 can be conveniently fed into the pressure wheel 31 and the carrier wheel 21.

[0088] Please refer again to Figure 2 In one embodiment, the other end of the pressure wheel shaft 3 is provided with a hook plate 32 and a hook plate elastic member 33 connecting the hook plate 32 and the pressure wheel shaft 3, the first support 11 is provided with a hook table 13 corresponding to the hook plate 32, and the hook plate elastic member 33 drives the hook plate 32 to rotate to maintain the lockingly connected state with the hook table 13.

[0089] Specifically, the hook plate 32 is rotationally connected with the pressure roller shaft 3 by a pin shaft, and the hook plate elastic member 33 connects the upper part of the hook plate 32 with the end of the pressure roller shaft 3. The hook plate elastic member 33 includes but is not limited to a tension spring, and the tension of the hook plate elastic member 33 ensures that the hook plate 32 is in a vertical position with the pressure roller shaft 3 (a positioning block is arranged between the hook plate 32 and the pressure roller shaft 3 to maintain the vertical position of the hook plate 32), that is, the hook plate elastic member 33 pulls the hook plate 32 so that the hook plate 32 hooks the hooking table 13.

[0090] In detail, the first support 11 and the hooking table 13 are an integral molded part, the upper part of the hooking table 13 is an inclined surface, and the lower part is a flat surface. When the inclined surface of the hook plate 32 slides over the inclined surface of the hooking table 13, the hook plate 32 hooks the flat surface of the lower part of the hooking table 13 under the action of the tension spring, thereby ensuring the stability of the pressure roller 31 in contact with the carrier roller 21.

[0091] By adopting the above technical solution, the stability of the pressure roller 31 in contact with the carrier roller 21 is improved.

[0092] In an embodiment, the carrier roller 21 and the pressure roller 31 are arranged up and down along a first direction, and the first clamping roller 41 and the second clamping roller 42 are arranged left and right along a second direction, the first direction being perpendicular to the second direction, and the first direction and the second direction being both perpendicular to the cable-in direction X of the cable 10.

[0093] Specifically, the carrier roller 21 and the pressure roller 31 are used to control the relative fixation of the cable 10 in the first direction, that is, the cable 10 does not move up and down in the first direction; and the first clamping roller 41 and the second clamping roller 42 are used to control the relative fixation of the cable 10 in the second direction, that is, the cable 10 does not move left and right in the second direction.

[0094] By adopting the above technical solution, the movement of the cable 10 is controlled in two mutually perpendicular directions, and the movement of the cable 10 in the first direction and the second direction is limited, so that the cable 10 can only move along the cable-in direction X, further improving the stability of the movement of the cable 10.

[0095] Please refer again to Figure 1 In an embodiment, the bottom of the base 1 extends downwardly with a plurality of clamping claws 14, and the plurality of clamping claws 14 enclose a clamping opening for clamping the guard roller sill 30 of the wharf 20.

[0096] Specifically, the plurality of clamping claws 14 form a lower "U"-shaped structural member, the inner width of the clamping opening of the structural member is greater than the thickness of the guard roller sill 30, preferably greater than 50 mm, and the height of the structural member is slightly lower than the height of the guard roller sill 30.

[0097] By adopting the above technical solution, the base 1 can be clamped on the guard roller sill 30, and the convenience of installation of the cable guiding device 100 is improved.

[0098] In one embodiment, the bottom of the base 1 is provided with a transverse plate 5 connected with two adjacent clamping claws 14, and the transverse plate 5 is provided with a locking member 51 for abutting against the fender 30.

[0099] Specifically, the transverse plate 5 is located on the side of the fender 30 away from the sea surface, so that the shore hand can operate the locking member 51 on the shore. In this embodiment, the locking member 51 includes but is not limited to a locking screw rod.

[0100] In detail, the transverse plate 5 is arranged between the two clamping claws 14 on the front of the base 1, and a fixed nut is arranged in the middle of the transverse plate 5. The locking screw rod matched with the nut can be forced to fix the base 1 and the fender 30 of the pier 20.

[0101] By using the above technical scheme, the connection between the cable guide device 100 and the fender 30 is more stable.

[0102] The above only describes the preferred embodiments of the present application and is not intended to limit the present application. Any modifications, equivalent replacements and improvements made within the spirit and principle of the present application shall be included in the protection scope of the present application.
