Description

Technical Field

[0002] The bollard is an indispensable equipment in the ship's mooring system. It is mainly used to fix the cable to ensure the stability and safety of the ship when docking or anchoring. In actual mooring work, the cable needs to be wrapped around the bollard and fixed by friction. The safety of the bollard is directly related to the stability of the ship's anchoring. The current anti-entrapment bollards for ship docking are not convenient to prevent pinching when wrapping the cable. The fixed bollards are not safe. Once the hand is clamped by the cable, it is difficult to pull it out. It is also not convenient to automatically control the switching of the cable position corresponding to the cable lead hole. The long-term local friction and squeezing of the cable by the cable lead hole will affect the overall service life. It is not convenient to prompt the switching position every time the cable is fixed, which reduces safety.

At the same time, the structure uses the winding control part 3 to ensure that the structure can be limited and pulled back, so as to ensure that it can be stably fixed after the cable is wound and maintain the stability of mooring. When the cable is wound on the movable plate 201, the cable will squeeze the detection strip 301, driving the switch 302 to be pressed. At this time, the limit electromagnet 203 can be demagnetized, and under the compression of the spring above the limit pin 204, the limit pin 204 can be inserted into the plug-in column 103 for limiting by utilizing the chamfered structure of the front side of the plug-in column 103. At this time, the movable plate 201 can be pulled back, driving the limit pin 602 to be inserted into the socket on the fixed mounting plate 101. For large ships, the pull-back wire rod 102 can be replaced with a hydraulic cylinder.

[0034] Among them, the anti-collapse component 4 includes: an anti-collapse connecting frame 401 and a connecting tension spring 402, two anti-collapse connecting frames 401 are fixedly installed on the movable plate 201 by bolts; the inner sides of the two anti-collapse connecting frames 401 are respectively fixedly installed with connecting tension springs 402; the anti-collapse connecting frame 401 is located in front of the two winding columns 202; the anti-collapse component 4 also includes: an installation sleeve 403, an electrical spring 4031, a protective rubber tube 404 and a cable guide hole pad 4041, the installation sleeve 403 is fixedly installed at the ends of the two connecting tension springs 402; a protective rubber tube 404 is fixedly installed on the installation sleeve 403; the diameter of the protective rubber tube 404 is larger than the cable; the inner side of the installation sleeve 403 is fixed A circle of power-connecting spring clips 4031 is installed, and the circle of power-connecting spring clips 4031 are elastic steel sheet structures; a cable-drawing hole pad 4041 is fixedly installed on the protective rubber tube 404; the cable-drawing hole pad 4041 is used to fit the cable-drawing hole, and the anti-collapse part 4 can be used for collapse protection. The protective rubber tube 404 can be used for protection on the outside of the cable. Once the cable inside the protective rubber tube 404 breaks, the protective rubber tube 404 can play a role in buffering and reducing speed. At the same time, the structure is simple and flexibility can be guaranteed. This structure uses the protective rubber tube 404 to protect the outside of the cable, which can reduce wear and tear, and increase the service life of the cable, and does not affect the normal retraction and release of the cable.

[0035] The cable detection part 5 comprises: an installation ring 501, an electric connection fixing strip 502 and a cable bonding piece 503, wherein the installation ring 501 is fixedly installed at the end of the protective rubber tube 404; a circle of electric connection fixing strip 502 is fixedly installed on the installation ring 501; a circle of cable bonding piece 503 is fixedly installed on the installation ring 501, and each circle of cable bonding piece 503 is an elastic structure; the cable bonding piece 503 is elastically bonded to the electric connection fixing strip 502; the electric connection fixing strip 502 and the cable bonding piece 503 are connected in series with the indicator light and the power supply outside. The cable detection part 5 can be used to detect the surface diameter of the cable. Once impurities are attached to the surface of the cable or local When the cable is bulging, it can be tested in time to avoid affecting the subsequent winding work, and real-time cable surface testing can be achieved. The detection of this structure is not affected by the position of the cable, and the detection is direct and efficient, which can reduce the missed detection rate of manual detection. At the same time, it can avoid auxiliary materials on the surface of the cable, such as shells, being wound together, causing the cable to be excessively squeezed or cut due to the mutual squeezing of the cables, thereby ensuring the service life of the cable of this structure. After the cable passes through the protective rubber tube 404, as the cable is retracted and released, the cable will squeeze the cable fitting piece 503. At this time, if the local diameter of the cable increases, the indicator lights connected to the power fixing strip 502 and the cable fitting piece 503 will light up to prompt.

[0036] Embodiment 2, on the basis of embodiment 1, the insurance positioning member 6 comprises: an insurance electromagnet 601 and a limit pin 602, the insurance electromagnet 601 is fixedly installed inside the movable plate 201; the limit pin 602 is slidably inserted into the bottom of the movable plate 201, and the bottom of the limit pin 602 is chamfered; the limit pin 602 is inserted into the socket on the fixed mounting plate 101; the insurance electromagnet 601 is aligned with the limit pin 602; a spring is connected between the insurance electromagnet 601 and the limit pin 602; the insurance control member 7 comprises: a movable cylinder 701 and a positioning bolt 702, the movable cylinder 701 is used to be sleeved on the cable; the positioning bolt 702 is threadedly connected to the movable cylinder 701; the end of the positioning bolt 702 is pressed and fits the cable; a spring is arranged on the positioning bolt 702 There is a hand wheel; the moving cylinder 701 is located inside a circle of power-connected spring pieces 4031; the insurance control member 7 also includes: a conducting cylinder 703, and the moving cylinder 701 is fixedly sleeved with the conducting cylinder 703; a circle of power-connected spring pieces 4031 elastically fit the conducting cylinder 703; the power-connected spring pieces 4031, the conducting cylinder 703 and the insurance electromagnet 601 are connected in series with the power supply. The insurance control member 7 can be used for insurance control, which can be used to control the cable when actually retracting and releasing the cable, so as to avoid that the cable is attached to the cable lead hole at a single local position every time it is moored. If things go on like this, the pressure at the local position of the cable will increase, which will reduce its overall service life, thereby causing safety hazards such as collapse and breakage. This structure can replace the moving disk 201 when the cable is released and the moving disk 201 needs to be positioned. The position of the movable drum 701, otherwise the positioning work cannot be achieved, the structure is more reasonable, and manual forgetting to operate to replace the position of the movable drum 701 is avoided. The structure is simple to operate, and can improve the uniformity of cable use, thereby improving the protection effect of the structure on the cable. The safety positioning member 6 can ensure the stability of the structure after actual positioning, and avoid falling off. The structure is more reasonable, ensuring stable mooring. After the cable is released, as the cable is fixed, the movable drum 701 needs to stagger the power-connecting spring piece 4031. At this time, the power-connecting spring piece 4031 is no longer powered, and the safety electromagnet 601 will not magnetically attract the limit pin 602. The limit pin 602 can be normally inserted into the socket on the fixed mounting plate 101 under the pressure of the upper spring to limit the position, and the next cable winding is carried out. In order to ensure that the movable plate 201 can slide and displace normally to prevent pinching, the length of the cable needs to be aligned with the position of the conductive tube 703 and the power-connecting spring piece 4031, so that the safety electromagnet 601 can be electromagnetically attracted to the magnetic limit pin 602 to release the limit work. In this way, after the cable is wound, when the magnetic limit pin 602 is reinserted into the fixed mounting plate 101, the position of the movable tube 701 needs to be moved to stagger the power-connecting spring piece 4031, and then the positioning bolt 702 is tightened to position the cable, thereby indirectly controlling the length of the cable released, that is, the position where the cable touches the cable lead hole, to avoid long-term force at a single position, and to facilitate marking by the staff, combined with the plug-in limit function of the magnetic limit pin 602 for control.

[0037] The working principle of this embodiment is as follows: first, the cable is manually wound around the two winding posts 202, and then the movable disk 201 can be moved on the fixed mounting plate 101 to prevent the cable from pulling and clamping the staff. As the cable is wound around the movable disk 201, the cable will squeeze the detection strip 301, driving the switch 302 to be pressed. At this time, the limit electromagnet 203 can be demagnetized, and the limit pin 204 can be extended under the pressure of the spring above the limit pin 204. At this time, the pull rod 102 can be manually rotated to drive the plug-in post 103 to be inserted into the movable disk 201. At this time, the chamfered structure of the front side of the plug-in post 103 is used. , the limit pin 204 can be inserted into the plug-in column 103 to limit the position. At this time, the movable plate 201 can be pulled back to drive the limit pin 602 to be inserted into the socket on the fixed mounting plate 101. For large ships, the pull-back wire rod 102 can be replaced with a hydraulic cylinder. After the cable passes through the protective rubber tube 404, once the cable inside the protective rubber tube 404 breaks, the protective rubber tube 404 can be used to buffer and reduce speed. As the cable is retracted and released, the cable will squeeze the cable fitting piece 503. At this time, if the local diameter of the cable increases, it will squeeze the cable fitting piece 503, and the cable fitting piece 503 will be staggered with the power connection fixing strip 502. , at this time, the indicator lights connected to the power fixing strip 502 and the cable fitting piece 503 will light up to prompt that after the cable is released, as the cable is fixed, the movable cylinder 701 needs to stagger the power connection spring piece 4031. At this time, the power connection spring piece 4031 is no longer powered, and the insurance electromagnet 601 will not magnetically attract the limit pin 602. The limit pin 602 can be normally inserted into the socket on the fixed mounting plate 101 under the pressure of the upper spring. When it is necessary to release the mooring later, the next cable winding is carried out. In order to ensure that the movable plate 201 can slide and displace normally to prevent pinching, the cable discharge length needs to meet the position of the conductive cylinder 703 to align with the power connection spring. The piece 4031 can release the limit work of the magnetic limit pin 602 set by the electromagnetic attraction of the safety electromagnet 601. In this way, after the cable is wound, when you want to reinsert the magnetic limit pin 602 into the fixed mounting plate 101, you need to move the position of the movable cylinder 701 to stagger the power-connecting spring piece 4031, and then tighten the positioning bolt 702 to position the cable. This position is the position where the current cable is in contact with the cable lead hole. At this time, when the next mooring is carried out, the position where the conductive cylinder 703 is in contact with the power-connecting spring piece 4031 will move on the cable, thereby indirectly controlling the length of the staggered cable release and avoiding local long-term stress.
