[0051] The utility model discloses a structure schematic diagram when being in the retracted state
[0052] In the description of the utility model, it is understood that the terms "upper", "lower", "left", "right", "front", "back", "top", "bottom" and the like indicate the orientation or positional relationship shown in the drawings, and are only for the convenience of describing the utility model and simplifying the description, and do not indicate or imply that the devices or elements referred to must have a particular orientation, be constructed and operated in a particular orientation, and therefore cannot be understood as limiting the utility model. It should be understood that the utility model uses the terms "first", "second" and the like to describe various information, but these information should not be limited to these terms, and these terms are only used to distinguish the same type of information from each other. For example, without departing from the scope of the utility model, the "first" information can also be referred to as "second" information, and similarly, the "second" information can also be referred to as "first" information.
[0053] As shown in Figures 1-13 , in the first aspect, the utility model discloses a gangway telescopic boom for adjusting the outward swing angle of gangway 4 relative to deck 9, as shown in Figure 1 , the transition plate 41 is horizontally rotatably installed on the deck 9, one end of the gangway 4 is vertically rotatably installed on the transition plate 41 (so that the gangway 4 can swing up and down along the vertical direction relative to the transition plate 41), and the other end of the gangway 4 is provided with a boarding plate 42; the gangway telescopic boom comprises a first boom 1, the first boom 1 is horizontally arranged along the width direction of the ship body, one end of the first boom 1 is installed on the deck 9; a second boom 2 is slidably connected to the first boom 1 along the length direction of the first boom 1; a first guide wheel set cooperating with the steel wire rope 5 is arranged on the second boom 2, and a second guide wheel set cooperating with the steel wire rope 5 is arranged on the gangway 4; the steel wire rope 5 passes through the first guide wheel set and the second guide wheel set, and both ends of the steel wire rope 5 are connected to the deck 9, so that the gangway 4 is suspended below the second boom 2; releasing the steel wire rope 5 makes the gangway 4 swing downward relative to the transition plate 41, so that the end of the gangway 4 far from the transition plate 41 (the boarding plate 42) abuts against the wharf ground, so that personnel can get on and off the ship; retracting the steel wire rope 5 makes the gangway 4 swing upward and reset relative to the transition plate 41; and a driving member 3 is connected between the first boom 1 and the second boom 2, for driving the second boom 2 to move relative to the first boom 1.
[0054] The embodiment in the specific implementation process is as follows: as shown in Figure 1 , in the initial state, the gangway 4 is in the parallel state with the ship body (at this time, the telescopic boom is in the retracted state), when the ship needs to be berthed and personnel get on and off the ship, the driving member 3 is controlled to work and drive the second boom 2 to move relative to the first boom 1, so that the second boom 2 moves away from the ship body, and with the movement of the second boom 2, the gangway 4 suspended below the second boom 2 is also moved synchronously, since the transition plate 41 is rotatably installed on the deck 9, the other end of the gangway 4 will also move alongFigure 1 The gangway 4 is swung in the direction of the arrow to a set angle, and then the control driving member 3 stops working. It should be noted that during the process of the telescopic boom driving the gangway 4 to swing outward, a certain length of the steel wire rope 5 needs to be released synchronously to ensure that the gangway 4 can move relative to the second boom 2 (for the purpose of cooperating with the telescopic boom to extend to drive the gangway 4 to swing outward by a certain angle). When the gangway 4 is swung to a set angle, the staff further releases the steel wire rope 5, and the gangway 4 swings downward relative to the transition plate 41 under the action of its own gravity, so that the other end (boarding plate 42) of the gangway 4 abuts against the ground of the wharf (since the gangway 4 has swung outward by a certain angle relative to the ship body, the boarding plate 42 is far away from the edge position of the wharf at this time, which is convenient for personnel to get on and off the ship). At this time, the ground personnel can get on the gangway 4 and get on the ship (the personnel on the ship get on the gangway 4 through the transition plate 41 and get off the ship). When the personnel get on and off the ship are completed, the gangway 4 needs to be retracted, and the retraction process is the reverse process of the above process, which will not be described in detail here.
[0055] In some embodiments of the present application, a rotating member 95 for winding the steel wire rope 5 is arranged on the deck 9. The rotating member 95 rotates to release the steel wire rope 5 and rotates in the opposite direction to retract the steel wire rope 5. The rotating member 95 rotates to release the steel wire rope 5, so that the steel wire rope 5 is fixedly connected to the deck 9 after passing through the first guide wheel set and the second guide wheel set.
[0056] In some embodiments of the present application, as shown in Figure 3 、 Figure 4 、 Figure 5 、 Figure 6 The first guide wheel set includes a fourth pulley 22, a fifth pulley 23 and a sixth pulley 24 rotatably installed on one side of the second boom 2 along the width direction, and the fourth pulley 22, the fifth pulley 23 and the sixth pulley 24 are arranged at intervals along the length direction of the second boom 2. The first guide wheel set further includes two second pulleys 62 rotatably installed on the other side of the second boom 2 along the width direction. The second guide wheel set includes two first pulleys 6 rotatably installed on the side wall of the gangway 4 along the width direction. The axial directions of the fourth pulley 22, the fifth pulley 23, the sixth pulley 24 and the second pulleys 62 are perpendicular to the axial direction of the first pulleys 6.
[0057] The steel wire rope 5 is released so that the steel wire rope 5 passes through the fourth pulley 22, the first pulley 6, the two second pulleys 62, the first pulley 6, the sixth pulley 24 and the fifth pulley 23 in sequence and is fixedly connected to the deck 9, so that the gangway 4 swings downward relative to the transition plate 41 under the action of its own gravity, so that the boarding plate 42 abuts against the ground of the wharf.
[0058] After the steel wire rope 5 is released from the deck 9, it firstly passes through the fourth pulley 22, then is guided by the first pulley 6 far away from the deck 9, then passes through the two second pulleys 62, and finally is fixedly connected to the deck 9 after passing through the first pulley 6 close to the deck 9, the sixth pulley 24 and the fifth pulley 23; since the axial directions of the two first pulleys 6 are perpendicular to the axial directions of the second pulleys 62 and the sixth pulley 24, in order to better guide the steel wire rope 5 (so as to prevent the steel wire rope 5 from being separated from the pulleys), two seventh pulleys 25 are rotatably installed on the lower end surfaces of the two sides of the second boom 2 in the width direction in this embodiment (i.e., four seventh pulleys 25 are provided in total, and the axial directions of the seventh pulleys 25 are arranged perpendicular to the length direction of the deck 9), as shown in Figure 5 , the two seventh pulleys 25 far away from the deck 9 are arranged between the fourth pulley 22 and the first pulley 6 and between the second pulley 62 and the first pulley 6, as shown in Figure 4 , the two seventh pulleys 25 close to the deck 9 are arranged between the second pulley 62 and the first pulley 6 and between the sixth pulley 24 and the first pulley 6, and the provision of the seventh pulleys 25 enables the steel wire rope 5 to better transition between the fourth pulley 22 and the first pulley 6, the first pulley 6 and the second pulley 62, and the sixth pulley 24 and the first pulley 6, so as to prevent the steel wire rope 5 from being separated from the pulleys. In the initial state, under the pulling action of the steel wire rope 5, the upper end surface of the gangway 4 abuts against the bottom wall of the second boom 2 (as shown in Figure 3 ), and when the steel wire rope 5 is released, the gangway 4 swings downward relative to the transition plate 41 under the action of its own gravity (so that the boarding plate 42 abuts against the wharf ground).
[0059] In some embodiments of the present application, as shown in Figure 9 , a first walking assembly 7 is arranged at the end of the first boom 1 far away from the deck 9 and is movably connected to the second boom 2 in the length direction of the second boom 2, and a second walking assembly 8 is arranged at the end of the second boom 2 close to the deck 9 and is movably connected to the first boom 1 in the length direction of the first boom 1; the cooperation of the first walking assembly 7 and the second walking assembly 8 enables the second boom 2 to be suspended on the first boom 1 and to move relative to the first boom 1; when the driving member 3 works, it can drive the second boom 2 to move relative to the first boom 1 towards the direction far away from the deck 9 or towards the direction close to the deck 9, so as to swing the gangway 4 outward by a certain angle or to retract the gangway 4 to a state parallel to the length direction of the ship body.
[0060] In some embodiments of the present application, as shown in Figure 10As shown, the first walking assembly 7 comprises two first mounting frames 71, which are correspondingly mounted on the two sides of the first boom 1 along the width direction; the first mounting frame 71 is rotatably mounted with the first walking wheels 72 arranged in an up-down interval; the upper end of the second boom 2 has the first clamping plate 21 extending along the length direction of the second boom 2, and the outer periphery of the two first walking wheels 72 on the same side is correspondingly pressed against the upper and lower ends of the first clamping plate 21; as shown Figure 13 As shown, the second walking assembly 8 comprises two second mounting frames 81, which are correspondingly mounted on the two sides of the second boom 2 along the width direction; the second mounting frame 81 is rotatably mounted with the second walking wheels 82 arranged in an up-down interval; the lower end of the first boom 1 has the second clamping plate 11 extending along the length direction of the first boom 1, and the outer periphery of the two second walking wheels 82 on the same side is correspondingly pressed against the upper and lower ends of the second clamping plate 11.
[0061] As shown Figure 9 As shown Figure 8 As shown, when the driving member 3 works and drives the second boom 2 to move relative to the first boom 1, the matched first walking wheels 72 walk along the first clamping plate 21, and the matched second walking wheels 82 walk along the second clamping plate 11; under the cooperation of the two matched first walking wheels 72 and the first clamping plate 21, and under the cooperation of the two matched second walking wheels 82 and the second clamping plate 11, the second boom 2 can move along the length direction of the first boom 1 and be connected to the first boom 1.
[0062] As shown Figure 11 , Figure 12 As shown, the first walking assembly 7 further comprises the first auxiliary frame 73 mounted on the first mounting frame 71, the first auxiliary frame 73 is arranged between the two first walking wheels 72 on the same side along the length direction of the first boom 1, and the two ends of the first auxiliary frame 73 are rotatably mounted with the first auxiliary wheels 74, as shown Figure 10 As shown, the outer periphery of the first auxiliary wheel 74 is pressed against the side wall of the first clamping plate 21 along the width direction; as shown Figure 13 As shown, the second walking assembly 8 further comprises the second auxiliary frame 83 mounted on the second mounting frame 81, the second auxiliary frame 83 is arranged between the two second walking wheels 82 on the same side along the length direction of the second boom 2, and the two ends of the second auxiliary frame 83 are rotatably mounted with the second auxiliary wheels 84, and the outer periphery of the second auxiliary wheel 84 is pressed against the side wall of the second clamping plate 11 along the width direction; as shown Figure 8 , Figure 9 , Figure 10 , Figure 13As shown, when the second boom 2 moves relative to the first boom 1, the movement of the second boom 2 relative to the first boom 1 is made more stable by the cooperation of the first auxiliary wheel 74 and the first clamping plate 21 located on both sides, and by the cooperation of the second auxiliary wheel 84 and the second clamping plate 11 located on both sides. The cooperation between the traveling wheel and the upper and lower ends of the clamping plate is used to realize the movable connection of the second boom 2 to the first boom 1. The cooperation between the auxiliary wheel and the side wall of the clamping plate is used to limit and constrain the movement trajectory of the second boom 2 relative to the first boom 1, so that the second boom 2 will not produce displacement in the direction perpendicular to the length of the first boom 1 during the movement of the second boom relative to the first boom 1.
[0063] In some embodiments of this application, the driving component 3 is a hydraulic cylinder. The hydraulic cylinder has a fixed end and a telescopic end. The fixed end is installed on the first boom 1, and the telescopic end is connected to the second boom 2. The hydraulic cylinder is connected to a controller, which controls the extension and retraction of the hydraulic cylinder, thereby driving the second boom 2 to move along the length extension direction of the first boom 1.
[0064] Secondly, embodiments of this application provide a gangway retraction mechanism, such as... Figure 2 As shown, the system includes a frame 92 mounted on a deck 9, and a rotating component 95 mounted on the frame 92. The rotating component 95 releases or retracts the wire rope 5 by rotating. The rotating component 95 is a winding roller rotatably mounted on the frame 92. The wire rope 5 is wound around the winding roller, which is connected to a motor. Controlling the rotation angle and direction of the motor controls the length of the wire rope 5 released or retracted by the winding roller. Figure 2 As shown, the frame 92 is provided with a fixing part for fixing the steel wire rope 5, and the fixing part is a fixed pulley 97 fixedly installed on the frame 92; and the gangway telescopic boom in the above embodiment; as Figure 2 As shown, an eighth pulley 96 is rotatably mounted on the frame 92; after the wire rope 5 is released from the winding roller, it is guided in sequence by the eighth pulley 96, the fourth pulley 22, the first pulley 6 on the side away from the deck 9, the two seventh pulleys 25, the two second pulleys 62, the two seventh pulleys 25, the first pulley 6 on the side close to the deck 9, the sixth pulley 24, and the fifth pulley 23 before being fixedly connected to the fixed pulley 97. The downward swing angle of the gangway 4 is controlled by controlling the release amount of the wire rope 5.
[0065] In some embodiments of this application, the first boom 1 is rotatably mounted on the deck 9, so that the gangway telescopic boom has a horizontally positioned working position and a vertically positioned retracted position; the rotating component 95 releases or retracts the wire rope 5 to drive the gangway telescopic boom to switch between the working position and the retracted position; the deck 9 is provided with vertically extending support columns 91 to support the gangway telescopic boom when it is in the working position (so that the telescopic boom can be stably positioned in a horizontal working position); such as Figure 1As shown, the platform 93 is rotatably mounted along the length direction perpendicular to the deck 9, and the rotation shaft of the platform 93 is coaxially arranged with the rotation shaft of the first boom 1; the transition plate 41 is horizontally rotatably mounted on the platform 93. When the gangway 4 is used, the operator controls the rotating member 95 to retract the steel wire rope 5, drives the boarding plate 42 arranged on the gangway 4 to gradually move upwards, so that the gangway 4 moves upwards to the horizontal state and the upper end surface of the gangway 4 abuts against the bottom wall of the second boom 2, at this time, the steel wire rope 5 is continuously retracted, and the cooperation of the steel wire rope 5 and the gangway 4 starts to drive the telescopic boom to rotate relative to the deck 9 (at this time, the platform 93 also synchronously rotates relative to the deck 9 to cooperate with the rotation of the telescopic boom), so that the telescopic boom changes from the horizontal working position to the vertical storage position, so that the telescopic boom rotates 90°, and the rotating member 95 stops rotating at this time, and the switching of the telescopic boom from the working position to the storage position is completed; when the gangway 4 needs to be used, the operation process is the reverse process of the above process, which will not be described in detail here.
[0066] In some embodiments of the present application, as shown in Figure 1 As shown, the transmission rod 94 is arranged between the first boom 1 and the platform 93, and the two ends of the transmission rod 94 are connected to the rotation shaft of the first boom 1 and the rotation shaft of the platform 93, respectively, when the rotating member 95 releases the steel wire rope 5, the telescopic boom gradually rotates from the vertical state to the horizontal state, and the transmission rod 94 synchronously drives the platform 93 to rotate, so that the telescopic boom is more stable when switching between the storage position and the working position, and the stress of each part is more balanced.
[0067] In some embodiments of the present application, as shown in Figure 2 As shown, the gangway folding and unfolding mechanism further comprises an abutting rod 921 movably connected to the frame 92 along the length direction perpendicular to the frame 92, and the frame 92 is provided with an elastic member 922 which can be compressed along the length direction perpendicular to the frame 92; when the gangway telescopic boom is in the storage position, the abutting rod 921 is pressed against the first boom 1 under the action of the elastic member 922; so that the abutting rod 921 applies a thrust to the gangway telescopic boom under the action of the elastic member 922, when the gangway 4 needs to be used, the rotating member 95 releases the steel wire rope 5, and when the steel wire rope 5 starts to be released, the telescopic boom gradually switches from the vertical state to the horizontal state under the action of the abutting rod 921, and the cooperation of the abutting rod 921 and the elastic member 922 provides a thrust for the initial movement of the telescopic boom, so that the telescopic boom automatically rotates under the action of the thrust when the steel wire rope 5 is released, to change from the vertical state to the horizontal state.
