Description

Technical Field

[0001] This invention relates to the field of ship casting equipment technology, specifically to a casting device structure. Background Technology

[0002] Anchor cables are ropes used on ships to support the weight of anchor stones. They reduce stress on the anchor chain when not in operation, extend service life, and are easier to replace, thus reducing overall operating costs. Traditional cable fixing methods involve using a rotatable pole. When the pole is rotated to the upright position, the end of the cable is fitted onto it, thus securing the cable. During cable deployment, a hydraulic cylinder drives the pole to rotate, causing the cable end to automatically detach from the pole, completing the deployment. However, this method of fixing cables has the following drawbacks: 1. Since the end of the steel cable is directly sleeved on the pole, the end of the steel cable sleeved on the pole may swing on the pole due to the influence of wind and waves, which may cause the end of the steel cable to slip off from the top of the pole, resulting in poor fixation stability. Second, during the cable-laying process, the weight of the anchor stone on the steel cable causes the cable end to detach from the pole at the moment of separation. Under tension, the cable bounces around in all directions, which can easily injure people on board and poses a safety hazard.

[0003] Therefore, this application proposes a cable thrower structure. Summary of the Invention

[0004] The purpose of this invention is to provide a cable thrower structure to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a cable thrower structure, comprising a first box housing a base plate mounted on a ship's deck, a base fixedly connected to the first box housing, a hook block hinged to the base, a movable buckle rotatably connected to the end of the hook block away from the base, a hook groove for hooking the end of a steel cable being formed between the hook block and the movable buckle, a locking pin being provided at the end of the movable buckle away from the hook block, and a hydraulic cylinder fixedly connected to the side wall of the first box housing, a sliding rod fixedly connected to the output shaft of the hydraulic cylinder, and a locking groove for engaging the locking pin being opened at the end of the sliding rod.

[0006] Preferably, a pull block is fixedly connected to the lower side of the hook block, and a guide rod is fixedly connected to the lower end of the pull block. An arc-shaped groove is opened on the side wall of the first housing, and the guide rod is slidably connected inside the arc-shaped groove. A slide rail is fixedly connected to the side wall of the first housing, and a slider is slidably connected to the slide rail. A guide groove is opened on the side wall of the slider, and the guide rod is slidably connected inside the guide groove. The slider is connected to the output shaft of the hydraulic cylinder.

[0007] Preferably, a bracket is fixedly connected to the side wall of the base plate, and a hub for guiding the sliding of the anchor chain is provided on the bracket. A cover plate for covering the upper side of the hub is provided above the bracket. A second housing is fixedly connected to the lower side of the base plate. The second housing is slidably connected to a sliding frame. The upper end of the sliding frame extends to the top of the cover plate and is fixedly connected to a locking block. The locking block penetrates the side wall of the cover plate and movably presses against the anchor chain on the hub. A screw is rotatably connected inside the second housing. The screw is engaged with the lower middle part of the sliding frame. A rotating rod is rotatably connected inside the first housing. One end of the rotating rod extends into the interior of the second housing and is engaged with the screw through a vertical gear set. A rack is fixedly connected to the output shaft of the hydraulic cylinder. The rack and the rotating rod are engaged through tooth meshing, thereby realizing drive.

[0008] Preferably, the sidewall of the substrate is provided with a sleeve for preventing the steel cable from being ejected.

[0009] Preferably, the upper side of the sleeve is provided with an opening groove to facilitate the insertion of the steel cable into the sleeve, and a rubber block is fixedly connected to the side wall of the steel cable.

[0010] Preferably, the sleeve is slidably connected to the side wall of the substrate, a third housing is fixedly connected to the side wall of the substrate, a connecting rod is fixedly connected to the side wall of the rack, the connecting rod extends to the side wall of the third housing and is fixedly connected to a first magnet, a second magnet is fixedly connected to the lower side of the sleeve, and the first magnet and the second magnet attract each other.

[0011] Preferably, a vertical plate is fixedly connected to the side wall of the first housing, and a reinforcing rod is fixedly connected to the side wall of the vertical plate, with the end of the reinforcing rod slidably connected inside the sliding rod.

[0012] Preferably, the first housing has an oil tank for holding hydraulic fluid fixedly connected inside, an oil pump for supplying oil to the inside of the cylinder is fixedly connected to the side wall of the oil tank, and a control module is fixedly connected inside the first housing for controlling the oil pump to perform related operations.

[0013] Compared with the prior art, the beneficial effects of the present invention are: 1. The present invention uses a snap-fit ​​to engage inside the slot, so that the movable buckle is fixed in the state of being attached to the hook block. In this way, the steel cable will be hooked inside the hook slot. Since the hook slot is in a closed state at this time, the end of the steel cable is not easy to come out of the hook slot, thereby increasing the stability of the steel cable end fixation and avoiding the slippage of the steel cable end due to the influence of wind, waves and other factors. 2. When the output shaft of the hydraulic cylinder pulls the sliding rod to move away from the locking pin, the end of the steel cable is disengaged from the locking pin. The sleeve restricts the movement of the steel cable, preventing it from bouncing around at the moment of release, thus effectively avoiding accidental injury to personnel from the ejected steel cable.

[0016] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0017] Please see Figure 1-16 This invention provides a technical solution: a cable throwing device structure. When the anchor stone is not thrown and is suspended on the hull, in order to reduce the weight of the anchor stone on the anchor chain and thus protect the anchor chain, a steel cable is used to suspend the anchor stone, thereby bearing its weight. The structure of this application is for this scenario and includes a base plate 1 installed on the hull deck, on which a first housing 2 is fixedly installed. Figure 1 As shown, a cover plate is fixedly connected to the top of the first housing 2. The cover plate can effectively protect the equipment inside the first housing 2 (such as preventing collisions and falls by personnel when not in operation). A base 3 is fixedly connected to the first housing 2. A hook block 4 is hinged to the base 3. A movable buckle 5 is rotatably connected to the end of the hook block 4 away from the base 3. A hook groove 6 is formed between the hook block 4 and the movable buckle 5 for hooking the end of the steel cable (here, a loop-type steel cable). Figure 7 and 10 The shape of the joint between the hook block 4 and the movable buckle 5 is slightly raised, so as to form a hook groove 6 space to block and catch the steel cable.

[0018] The movable buckle 5 is provided with a locking pin 7 at one end away from the hook block 4, and a hydraulic cylinder 8 is fixedly connected to the side wall of the first box 2. A sliding rod 9 is fixedly connected to the output shaft of the hydraulic cylinder 8, and a slot 901 for engaging the locking pin 7 is opened at the end of the sliding rod 9. like Figure 9 As shown, at this time, the locking pin 7 is disengaged from the slot 901, and the movable buckle 5 is in the open state on the hook block 4. At this time, the end of the steel cable is sleeved on the movable buckle 5, and the movable buckle 5 is rotated so that the movable buckle 5 is attached to the hook block 4. In this way, the steel cable will be hooked inside the hook groove 6. At this time, the output shaft of the hydraulic cylinder 8 drives the sliding rod 9 to move, so that the end of the sliding rod 9 moves towards the locking pin 7, so that the locking pin 7 is engaged inside the slot 901. At this time, the movable buckle 5 is fixed at the position attached to the hook block 4. like Figure 8 The arrows shown indicate the direction of the force exerted on the steel cable by the anchor stone. The hook block 4 is positioned in an arc shape when it connects to the hook groove 6 (e.g., Figure 9 As shown), when the movable buckle 5 is in the open state, the steel cable will slide off the hook groove 6 along the arc-shaped wall, thus enabling the steel cable to automatically detach from the inside of the hook groove 6. When anchoring is required, the output shaft of the hydraulic cylinder 8 drives the sliding rod 9 to move away from the locking pin 7, causing the locking pin 7 to move out of the inside of the locking groove 901. At this time, the movable buckle 5 is in the open state. Thus, under the force of the anchor, the steel cable slides along the arc-shaped wall of the hook block 4, causing the steel cable to flip and fold the movable buckle 5. Figure 9 As shown in the diagram, the end of the steel cable can be disengaged from the inside of the hook groove 6, thus completing the operation of throwing the anchor stone.

[0019] like Figure 5-10 As shown, during the anchor throwing operation, in order to further ensure that the end of the steel cable can be disengaged from the inside of the hook groove 6, specifically, a pull block 10 is fixedly connected to the lower side of the hook block 4, and a guide rod 11 is fixedly connected to the lower end of the pull block 10. An arc groove 12 is opened on the side wall of the first housing 2, and the guide rod 11 is slidably connected inside the arc groove 12. The center of the arc groove 12 coincides with the center of the hook block 4 rotating on the base 3. When the guide rod 11 slides inside the arc groove 12, the guide rod 11 drives the hook block 4 to rotate on the base 3 through the pull block 10. A slide rail 13 is fixedly connected to the side wall of the first housing 2, and a slider 14 is slidably connected to the slide rail 13. A guide groove 1401 is opened on the side wall of the slider 14, and the guide rod 11 is slidably connected inside the guide groove 1401. The slider 14 is connected to the output shaft of the hydraulic cylinder 8. When the hydraulic cylinder 8 drives the sliding rod 9 to move away from the locking pin 7, the output shaft of the hydraulic cylinder 8 will slide the slider 14 on the slide rail 13. When the slider 14 slides, the guide rod 11 will slide inside the guide groove 1401. At this time, the guide rod 11 will pull the end of the hook block 4 away from the base 3 downward through the pull block 10. This will allow the hook block 4 to rotate to an inclined state (as shown in the figure with the left end facing downward). This will further facilitate the automatic release of the end of the steel cable from the hook groove 6. This structure can help to hook the cable in the initial state and prevent jamming when throwing the cable.

[0020] In practical applications, due to the downward rotation of the hook block 4, interference may easily occur at the slot 901. To eliminate the above situation, the following two implementation methods can be adopted.

[0021] The first type, such as Figure 15 As shown, the shape of the slot 901 is changed from the original U-shape to an L-shape. Since the movable buckle 5 and the hook block 4 are hinged, the locking pin 7 can only be disengaged from the slot 901 by rotating upwards. Therefore, this type of structure of the slot 901 will not affect the stability. Furthermore, when the left end of the hook block 4 rotates downwards, there is no obstruction below the slot 901, so there will be no obstruction, which can improve the stability of operation.

[0022] The second type, such as Figure 16 As shown, the guide groove 1401 is changed from an inclined groove to a bent groove. In the initial stage of the hydraulic cylinder 8, the guide groove 1401 only drives the guide rod 11 to move horizontally. At this time, the hook block 4 will not rotate. When the slot 901 disengages from the pin 7, the guide rod 11 moves to the inclined part of the guide groove 1401. Only when the movement continues will the hook block 4 rotate to the inclined state, which is conducive to the automatic release of the steel cable end from the hook groove 6.

[0023] like Figure 1 , 5As shown in Figure 11, to further suspend the anchor stone on the hull and prevent it from falling, specifically, a bracket 15 is fixedly connected to the side wall of the base plate 1. A hub 16 for guiding the anchor chain is provided on the bracket 15. A winding wheel for winding the anchor chain is provided on the hull. The end of the anchor chain passes through the hub 16 and is fixedly connected to it, causing the hub 16 to guide the anchor chain. A shield 17 for covering the upper side of the hub 16 is provided above the bracket 15. A second housing 18 is fixedly connected to the lower side of the base plate 1. The second housing 18 is slidably connected to the sliding frame 19 (i.e., the lower part of the sliding frame 19 is slidably connected to the side wall of the second housing 18, and...). (It is limited to vertical up and down movement). The upper end of the sliding frame 19 extends to the top of the cover 17 and is fixedly connected to the locking block 23. The locking block 23 penetrates the side wall of the cover 17 and presses movably on the anchor chain on the hub 16. The second box 18 is rotatably connected to the inside of the screw 20. The screw 20 is meshed with the middle of the lower end of the sliding frame 19. The first box 2 is rotatably connected to the inside of the rotating rod 21. One end of the rotating rod 21 extends into the inside of the second box 18 and is meshed with the screw 20 through a vertical gear set. The output shaft of the oil cylinder 8 is fixedly connected to the rack 22. The rack 22 and the rotating rod 21 are connected by tooth meshing. When the output shaft of the hydraulic cylinder 8 moves with the sliding rod 9, the locking pin 7 engages inside the locking groove 901. At the same time, the output shaft of the hydraulic cylinder 8 also moves with the rack 22, which in turn causes the rack 22 to rotate with the rotating rod 21. This causes the rotating rod 21 to rotate with the screw 20 through the vertical gear set. At this time, the screw 20 will drive the sliding frame 19 to slide downward, so that the locking block 23 will press on the anchor chain of the hub 16, thereby fixing and locking the anchor chain on the hub 16 and preventing the anchor stone from falling off.

[0024] The structure of this part is optional in practical applications, and is not necessarily required.

[0025] like Figure 12 As shown, after the end of the steel cable detaches from the inside of the hook groove 6, the steel cable may bounce in any direction. To prevent accidental injury when the steel cable bounces, a sleeve 27 is provided on the side wall of the base plate 1 to prevent the steel cable from bouncing. In practical applications, the sleeve 27 needs to be of a certain length to prevent the steel cable from bouncing, but if it is too long, it will be difficult to pass through. Therefore, the upper side of the sleeve 27 is provided with an opening groove 29 to facilitate the insertion of the steel cable into the sleeve 27. The width of the opening groove 29 is larger than the diameter of the steel cable, so that the steel cable can be directly inserted into the inside of the sleeve 27 through the opening groove 29. However, the opening groove 29 may also cause the cable to detach from here and injure people. To solve this problem, the following two methods can be provided: In the first case, a rubber block 30 is fixedly connected to the side wall of the steel cable, such as... Figure 12As shown, when the steel cable is placed inside the sleeve 27, the rubber block 30 is positioned between the sleeve 27 and the hook groove 6. This prevents the steel cable from coming out of the opening groove 29 and also ensures that the steel cable is partially inside the sleeve 27 during installation.

[0026] The second type is that the shape of the opening groove 29 can be set to be non-linear, such as a broken line or a curve. When the steel cable is put into the sleeve 27, the steel cable can be bent and then passed through the opening groove 29. When it is released, the steel cable is taut due to the force and is not easy to leave from the non-linear opening groove 29.

[0027] Moreover, the second method can be fully integrated into the first method, thereby further improving stability.

[0028] In addition, regarding the rubber block 30, the end of the rubber block 30 near the sleeve 27 can be conical. The conical shape is conducive to the insertion of the rubber block 30 into the sleeve 27. Furthermore, the rubber block 30 and the sleeve are interference-fitted, which causes the rubber block 30 to slide into the sleeve 27 and then be tightly connected to the inner wall of the sleeve 27. This generates a certain amount of resistance, which can reduce the pull-out speed, prevent ejection and injury, and further improve safety. like Figure 12-14 As shown, the sleeve 27 is slidably connected to the side wall of the base plate 1. A third housing 24 is fixedly connected to the side wall of the base plate 1. A connecting rod 25 is fixedly connected to the side wall of the rack 22. The connecting rod 25 extends to the side wall of the third housing 24 and is fixedly connected to a first magnet 26. A second magnet 28 is fixedly connected to the lower side of the sleeve 27. The first magnet 26 and the second magnet 28 attract each other. Figure 14 As shown, when the end of the steel cable is engaged inside the hook groove 6, and the locking pin 7 is engaged inside the locking groove 901 by the hydraulic cylinder 8, the sleeve 27 is in the position as shown. Figure 14 As shown, when it is necessary to throw the anchor stone, when the output shaft of the hydraulic cylinder 8 pulls the sliding rod 9 to move away from the locking pin 7, the end of the steel cable is released from the locking pin. The sleeve 27 restricts the steel cable from jumping around at the moment of release, effectively preventing the steel cable from accidentally injuring personnel. To address the issue of setting up a rubber block 30, and to reduce operational difficulty and streamline processes while minimizing the risk of misoperation, the output shaft of the hydraulic cylinder 8 moves the connecting rod 25 via the rack 22. The first magnet 26 attracts the second magnet 28, causing the sleeve 27 to move towards the side of the rubber block 30, thus inserting the rubber block 30 into the sleeve 27. The rubber block 30 prevents the steel cable from ejecting from the opening slot 29. Furthermore, due to the interference fit between the rubber block 30 and the sleeve 27, the second magnet 28 moves with the sleeve 27, causing the first magnet 26 and the second magnet 28 to separate. This allows the rubber block 30 to slide and reset the sleeve 27, preventing the steel cable from rapidly ejecting from the end of the sleeve 27. This effectively prevents accidental injury from ejected steel cables. This method reduces the need for manual insertion of the rubber block 30 during reset, streamlining the process and avoiding the risk of forgetting this operation. When the anchor stone is lifted again by the steel cable instead of the anchor chain, that is, after the end of the steel cable is once again engaged in the inside of the hook groove 6, the output shaft of the hydraulic cylinder 8 causes the connecting rod 25 to move the first magnet 26 toward the second magnet 28, and then the first magnet 26 and the second magnet 28 are attracted to each other again. Then, through the mutual attraction between the first magnet 26 and the second magnet 28, the sleeve 27 can be driven to move toward the rubber block 30 along with the connecting rod 25 again. The operational scenario of this application's structure is as follows: First, the slot 901 has a certain depth. When the locking pin 7 is just inserted into the slot 901, it can fix the movable buckle 5. At this time, the locking block 23 has not yet locked the anchor chain, allowing the anchor chain to move on the hub 16 (the movement of the anchor chain is achieved by winding it up using a corresponding anchor chain winding device, which is not described in detail in the existing technology). Then, when the steel cable is hooked into the hook groove 6, the operation of the hydraulic cylinder 8 keeps the locking pin 7 in the state of just being inserted into the slot 901. At this time, the winding wheel of the anchor chain winds up an additional length of the anchor chain, causing the steel cable to be hooked into the hook groove 6 when the end of the steel cable is hooked into the hook groove 6. When the cable is in a slack state (so that pulling and moving operations can be performed), after the end of the steel cable is hooked inside the hook groove 6, a certain length of anchor chain can be released, so that the anchor chain is in a slack state. At this time, the steel cable replaces the anchor chain to suspend the anchor stone, which plays a role in protecting the anchor chain. When the steel cable replaces the anchor chain to suspend the anchor stone, the hydraulic cylinder 8 causes the locking pin 7 to slide into the innermost end of the locking groove 901. In this way, the locking block 23 also locks the anchor chain on the hub 16, which not only fixes the movable buckle 5, but also fixes the anchor chain (at this time, the anchor chain from the anchor stone to the hub 16 is in a slack state, that is, the force is transferred to the steel cable to improve the service life).

[0029] like Figure 4As shown, in order to increase the stability of the sliding rod 9, specifically, a vertical plate 31 is fixedly connected to the side wall of the first housing 2, and a reinforcing rod 32 is fixedly connected to the side wall of the vertical plate 31. The end of the reinforcing rod 32 is slidably connected to the inside of the sliding rod 9. When the sliding rod 9 slides, the sliding rod 9 is slidably connected to the reinforcing rod 32. At this time, the reinforcing rod 32 plays a stabilizing role for the sliding rod 9 and prevents the sliding rod 9 from tilting.

[0030] like Figure 5 As shown, in order to increase the stability of the sliding rod 9, specifically, an oil tank 33 for holding hydraulic fluid is fixedly connected inside the first housing 2. An oil pump 34 for supplying oil to the inside of the cylinder 8 is fixedly connected to the side wall of the oil tank 33. A control module 35 is fixedly connected inside the first housing 2. The oil pump 34 is electrically connected to the control module 35. The oil pump 34 and the control module 35 are connected to an external power source through a cable. The user can remotely send commands to the control module 35 to control the start and stop of the oil pump 34, causing the oil pump 34 to regularly flow the oil in the oil tank 33 and the cylinder 8, thereby controlling the output shaft of the cylinder 8 to extend and retract. The method by which the control module 35 controls the drive oil pump 34 to output the oil in the oil tank 33 to the cylinder 8 is existing technology and is now widely used, so it will not be described in detail in this invention.

When the hydraulic cylinder (8) drives the sliding rod (9) to move away from the locking pin (7), the output shaft of the hydraulic cylinder (8) will carry the slider (14) to slide on the slide rail (13). When the slider (14) slides, the guide rod (11) will slide inside the guide groove (1401). At this time, the guide rod (11) will pull the end of the hook block (4) away from the base (3) downward through the pull block (10), so that the hook block (4) rotates to the tilted state.

2. The cable thrower structure according to claim 1, characterized in that: The first housing (2) has an oil tank (33) for holding hydraulic fluid fixedly connected inside, and an oil pump (34) for supplying oil to the inside of the oil cylinder (8) is fixedly connected to the side wall of the oil tank (33).
