Description

Technical Field

[0001] The invention belongs to the technical field of marine equipment, and in particular relates to a marine anchor windlass auxiliary device which is convenient to fix. Background Art

[0002] In the field of shipbuilding, marine anchor windlasses are key equipment that are mainly responsible for the important task of retracting and releasing anchors and anchor chains. They are generally installed at the bow of a ship. The operating mechanism of this equipment is usually driven by mechanical transmission, or by electric, hydraulic or other power sources, so as to achieve the operation of reeling in or releasing the anchor chain, thereby achieving the goal of mooring and positioning the ship.

[0003] In actual application, marine anchor windlasses are often mounted on a support base, which can provide auxiliary support for the anchor windlass. The support base is generally provided with mounting holes, which are designed to dock with the docking holes on the deck and fixed with bolts. However, during the installation process, in order to accurately align the mounting holes with the docking holes on the deck, it is often necessary to manually lift and adjust the position of the support base. The whole process consumes a lot of manpower, which makes the installation operation extremely inconvenient.

[0004] In addition, the conventional support base has the defect that the height of the anchor machine cannot be flexibly adjusted according to specific needs in the process of assisting the anchor machine. Moreover, when the anchor machine is in use and the ship encounters turbulence, the conventional support base is difficult to implement effective shock absorption treatment for the anchor machine.

[0005] Therefore, we propose a conveniently fixed marine anchor windlass auxiliary device to solve the above problems. Summary of the invention

[0006] The object of the present invention is to provide a conveniently fixed marine anchor windlass auxiliary device in view of the above problems.

[0007] To achieve the above-mentioned purpose, the present invention adopts the following technical solutions: a conveniently fixed marine anchor machine auxiliary device, comprising a base, three nut seats are rotatably arranged in the base, and the three nut seats are all threadedly connected with support screws, the upper ends of the three support screws are commonly fixedly connected with a support plate, and a driving control mechanism matched with the three nut seats is arranged in the base, the support plate is fixedly connected with a fixed seat through multiple magnetic shock absorbing mechanisms, a vibration feedback mechanism is arranged on the fixed seat, a current control mechanism matched with the vibration feedback mechanism is arranged on the support plate, and the current control mechanism is electrically connected with the magnetic shock absorbing mechanism;

[0008] A plurality of mounting blocks are fixedly arranged on the lower side wall of the base, and mounting holes are opened on the mounting blocks. A plurality of hydraulic cylinders are fixedly arranged in the base, and openings corresponding to the hydraulic cylinders are opened on the lower side of the base. The output ends of the hydraulic cylinders pass through the corresponding openings and are fixedly connected with self-locking universal wheels.

[0009] In the above-mentioned conveniently fixed marine anchor windlass auxiliary device, the drive control mechanism is composed of a servo motor, a driving gear, a driven gear and a pulley assembly. The servo motor is fixedly arranged in the base, and the output end of the servo motor is fixedly sleeved with the driving gear. The driven gear is fixedly sleeved on one of the nut seats, and the driven gear is meshed with the driving gear. The three nut seats are connected by a pulley assembly.

[0010] In the above-mentioned conveniently fixed marine anchor windlass auxiliary device, the gear ratio between the driving gear and the driven gear is 1:2, and the three nut seats are distributed in a triangular shape.

[0011] In the above-mentioned conveniently fixed marine anchor machine auxiliary device, the magnetic shock absorbing mechanism includes a shock absorbing seat and a shock absorbing column, the shock absorbing seat is fixedly arranged on the support plate, the shock absorbing column is slidably connected to the shock absorbing seat through a first permanent magnetic slider, and a shock absorbing spring is fixedly arranged between the first permanent magnetic slider and the shock absorbing seat, and electromagnetic sheets in contact with the first permanent magnetic slider are embedded in the inner walls on both sides of the shock absorbing seat.

[0012] In the above-mentioned conveniently fixed marine anchor windlass auxiliary device, the vibration feedback mechanism is composed of multiple vibration sensing blocks and multiple ceramic piezoelectric sheets, each of the vibration sensing blocks is rotatably arranged on the lower side of the fixed seat, and the ceramic piezoelectric sheet is embedded in the corresponding vibration sensing block.

[0013] In the above-mentioned conveniently fixed marine anchor windlass auxiliary device, a protective shell for protecting the ceramic piezoelectric sheet is fixedly arranged on the fixing seat, and the protective shell cover is arranged on the corresponding vibration sensing block.

[0014] In the above-mentioned conveniently fixed marine anchor machine auxiliary device, the current control mechanism includes a control shell, an electromagnetic block, a second permanent magnetic slider and a sliding rheostat. The control shell is fixedly arranged on the lower side of the support plate, and the electromagnetic block and the sliding rheostat are both fixedly arranged in the control shell. The electromagnetic block is connected in parallel with each ceramic piezoelectric sheet.

The second permanent magnetic slider is fixedly connected to the sliding end of the sliding rheostat through an insulating rod, and the sliding rheostat is connected in series with each electromagnetic sheet.

[0015] In the above-mentioned conveniently fixed marine anchor windlass auxiliary device, a fixing block corresponding to the mounting block is fixedly arranged on the side wall of the base, and a laser positioning pen corresponding to the mounting hole is threadedly connected to the fixing block.

[0016] Compared with the existing technology, the advantages of a conveniently fixed marine anchor windlass auxiliary device are:

[0017] 1. In the installation and fixing process, the self-locking universal wheels carefully equipped on the device give the entire device excellent mobility, allowing the staff to easily move it to the designated installation position. The ingenious setting of the laser positioning pen further improves the convenience of device installation. The precise positioning light it emits provides an intuitive and accurate reference for the staff during the process of moving the device, which can assist the installation hole and the docking hole on the deck to align quickly and accurately. In addition, with the cooperation of the hydraulic cylinder, the self-locking universal wheel can be extended and retracted, and then during installation, the self-locking universal wheel can be retracted to ensure that the installation block is flush with the deck. The above innovative design significantly reduces the huge consumption of manpower in the traditional installation method, greatly shortens the time and energy required for installation, and not only that, the accuracy and efficiency of the installation have also been greatly improved, effectively avoiding repeated adjustments and delays caused by misalignment of the installation hole and the docking hole.

[0018] 2. In terms of height adjustment function, this device demonstrates high precision and flexibility. Through the exquisite coordination between the servo motor, driving gear, driven gear and pulley assembly, the three support screws can achieve synchronous and precise rotation control. This synchronization and precision make the height adjustment process of the anchor windlass smooth and reliable, which can meet the needs of various complex and diverse usage scenarios. The triangular distribution design of the three nut seats enables the three support screws to achieve triangular support, thereby improving the stability of the support.

[0019] 3. In terms of shock absorption performance, the magnetic shock absorption mechanism of the device is closely coordinated with the vibration feedback mechanism and the current control mechanism to build a set of efficient and adaptive shock absorption system. The shock absorption spring can respond quickly when the anchor machine vibrates, effectively absorb and buffer the vibration force, thereby reducing the impact of the vibration on the anchor machine and the entire device. At the same time, the magnetic attraction resistance between the electromagnetic sheet and the first permanent magnetic slider cleverly suppresses the excessive movement of the shock absorption spring during the energy release and rebound process, avoiding secondary vibration and potential damage that may be caused by excessive rebound.

[0020] 4. The ceramic piezoelectric sheet in the vibration feedback mechanism shows extremely high sensitivity, and can generate corresponding current changes in real time according to the amplitude changes of the vibration force of the anchor winch. The current control mechanism automatically and quickly adjusts the magnetic resistance of the electromagnetic sheet based on this change. When the vibration of the anchor winch is large, the magnetic resistance can be enhanced in time to further improve the shock absorption effect; when the vibration is small, the magnetic resistance is adjusted accordingly to ensure that the response of the shock absorption system is neither excessive nor insufficient. This adaptive shock absorption processing capability enables the device to always maintain excellent shock absorption performance when the anchor winch faces different degrees of vibration, greatly enhancing the stability and reliability of the device.

DETAILED DESCRIPTION

[0026] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0027] like Figure 1-Figure 4As shown, a conveniently fixed marine anchor machine auxiliary device comprises a base 1, in which three nut seats 2 are rotatably arranged, and the three nut seats 2 are all threadedly connected with support screws 3, the upper ends of the three support screws 3 are commonly fixedly connected with a support plate 4, and the base 1 is provided with a driving control mechanism 5 matched with the three nut seats 2.

[0028] The drive control mechanism 5 is composed of a servo motor 51, a driving gear 52, a driven gear 53 and a pulley assembly 54. The servo motor 51 is fixedly arranged in the base 1, and the output end of the servo motor 51 is fixedly sleeved with the driving gear 52, the driven gear 53 is fixedly sleeved on one of the nut seats 2, and the driven gear 53 is meshed with the driving gear 52. The three nut seats 2 are connected by the pulley assembly 54. Through the transmission cooperation of the driving gear 52, the driven gear 53 and the pulley assembly 54, the servo motor 51 can control the three nut seats 2 to rotate synchronously, thereby avoiding the cost of adding additional driving equipment.

[0029] The gear ratio of the driving gear 52 and the driven gear 53 is 1:2, and the three nut seats 2 are distributed in a triangle. The tooth number design of the driven gear 53 can slow down the rotation speed of the nut seat 2, so that the support screw 3 can control the anchor machine on the fixed seat 7 to slowly rise and fall, which is convenient for controlling the lifting height. The position distribution of the three nut seats 2 can make the three support screws 3 support in a triangular shape, improve the stability of the support, and enable the pulley and belt on the pulley assembly 54 to have better contact transmission.

[0030] The support plate 4 is fixedly connected to the fixed seat 7 through multiple magnetic shock-absorbing mechanisms 6. The magnetic shock-absorbing mechanisms 6 include a shock-absorbing seat 61 and a shock-absorbing column 62. The shock-absorbing seat 61 is fixedly arranged on the support plate 4. The shock-absorbing column 62 is slidably connected to the shock-absorbing seat 61 through the first permanent magnetic slider 15, and a shock-absorbing spring 16 is fixedly arranged between the first permanent magnetic slider 15 and the shock-absorbing seat 61. Electromagnetic plates 17 in contact with the first permanent magnetic slider 15 are embedded on the inner walls of both sides of the shock-absorbing seat 61. Through the provided shock-absorbing spring 16, the deformation of the shock-absorbing spring 16 can be used to buffer the vibration force of the anchor machine, and the magnetic attraction resistance between the electromagnetic plate 17 and the first permanent magnetic slider 15 can effectively offset the rebound energy release of the shock-absorbing spring 16, thereby ensuring the overall shock absorption of the device.

[0031] A vibration feedback mechanism 8 is arranged on the fixed seat 7, and the vibration feedback mechanism 8 is composed of a plurality of vibration sensing blocks 81 and a plurality of ceramic piezoelectric sheets 82. Each vibration sensing block 81 is rotatably arranged on the lower side of the fixed seat 7, and the ceramic piezoelectric sheet 82 is embedded in the corresponding vibration sensing block 81. The ceramic piezoelectric sheet 82 can generate corresponding current changes according to the amplitude of the vibration force applied to the vibration sensing block 81.

[0032] A protective shell 18 for protecting the ceramic piezoelectric piece 82 is fixedly arranged on the fixing seat 7. The protective shell 18 is arranged on the corresponding vibration sensing block 81. The setting of the protective shell 18 can protect the ceramic piezoelectric piece 82 from being corroded by seawater vapor.

[0033] The support plate 4 is provided with a current regulating mechanism 9 matched with the vibration feedback mechanism 8, and the current regulating mechanism 9 is electrically connected to the magnetic shock absorbing mechanism 6. The current regulating mechanism 9 includes a regulating shell 91, an electromagnetic block 92, a second permanent magnetic slider 93 and a sliding rheostat 94. The regulating shell 91 is fixedly arranged on the lower side of the support plate 4, and the electromagnetic block 92 and the sliding rheostat 94 are both fixedly arranged in the regulating shell 91. The electromagnetic block 92 is connected in parallel with each ceramic piezoelectric sheet 82. The electromagnetic block 92 is fixedly connected to the second permanent magnetic slider 93 through a reset spring 19, and the second permanent magnetic slider 93 is slidably connected to the regulating shell 91. The second permanent magnetic slider 93 is connected to the sliding rheostat 94 through an insulating rod 20. The sliding end is fixedly connected, and the sliding rheostat 94 is connected in series with each electromagnetic sheet 17. Through the set electromagnetic block 92, the magnetism of the electromagnetic block 92 can be automatically changed based on the current change generated by the vibration feedback mechanism 8 under different vibration conditions, thereby changing the suction force between the electromagnetic block 92 and the second permanent magnetic slider 93, so that the second permanent magnetic slider 93 can automatically adjust the resistance value of the sliding rheostat 94 connected to each electromagnetic sheet 17 circuit, and then based on the vibration feedback of the anchor machine, the magnetic attraction resistance between the electromagnetic sheet 17 and the first permanent magnetic slider 15 can be automatically adjusted, so that the magnetic shock absorption mechanism 6 can feedback a suitable shock absorption effect based on different vibration conditions of the anchor machine.

[0034] A plurality of mounting blocks 10 are fixedly provided on the lower side wall of the base 1, and mounting holes 11 are provided on the mounting blocks 10, a plurality of hydraulic cylinders 12 are fixedly provided in the base 1, and an opening 13 corresponding to the hydraulic cylinder 12 is provided on the lower side of the base 1, the output end of the hydraulic cylinder 12 passes through the corresponding opening 13 and is fixedly connected with a self-locking universal wheel 14, a fixing block 21 corresponding to the mounting block 10 is fixedly provided on the side wall of the base 1, and a laser positioning pen 22 corresponding to the mounting hole 11 is threadedly connected on the fixing block 21, the setting of the laser positioning pen 22 can utilize the emitted positioning light so that when the staff moves the position of the mounting hole 11 through the self-locking universal wheel 14, the auxiliary mounting hole 11 is aligned with the docking hole on the deck, which greatly improves the convenience of installation.

[0035] The operating principle of the present invention is now described as follows:

[0036] When using the device, the anchor windlass is fixedly mounted on the fixing seat 7 by welding to ensure the stability of the connection between the two. Then, the staff can conveniently move the entire device to the installation position through the self-locking universal wheels 14. When moving to the installation position, the laser positioning pens 22 are activated to align the positioning light emitted by the laser positioning pens 22 with the corresponding docking holes on the deck. After alignment, the self-locking universal wheels 14 are retracted onto the base 1 by the hydraulic cylinder 12, so that the mounting block 10 is flush with the deck. Then, the staff can use bolts to match the mounting holes 11 and the docking holes on the deck to fix the entire auxiliary device on the deck.

[0037] When the height of the anchor windlass needs to be adjusted, the servo motor 51 controls the driving gear 52 to rotate forward or reverse, and under the transmission cooperation of the driven gear 53 and the pulley assembly 54, the three nut seats 2 will rotate forward or reverse synchronously, so that the three supporting screws 3 can control the anchor windlass on the fixed seat 7 to rise and fall, thereby achieving height adjustment;

[0038] When the anchor windlass on the fixed seat 7 vibrates, the shock-absorbing spring 16 will be deformed to offset the vibration force. When the shock-absorbing spring 16 releases energy and rebounds, the magnetic attraction resistance between the electromagnetic sheet 17 and the first permanent magnetic slider 15 can be used to consume the rebound energy of the shock-absorbing spring 16 to avoid excessive rebound, so as to ensure the overall shock-absorbing effect of the device. When the anchor windlass vibrates too much, the vibration amplitude of each vibration sensing block 81 will increase, so that the vibration force on the ceramic piezoelectric sheet 82 on the vibration sensing block 81 will increase, and then the current generated by the ceramic piezoelectric sheet 82 will increase, thereby increasing the electrical connection with it. The current passed through the connected electromagnetic block 92 increases, so that the magnetism of the electromagnetic block 92 is enhanced, and then the electromagnetic block 92 will attract the second permanent magnetic slider 93 to move back a certain distance, so that the second permanent magnetic slider 93 pulls the sliding end of the sliding rheostat 94 to move a certain distance through the insulating rod 20, so that the resistance value of the sliding rheostat 94 connected to each electromagnetic sheet 17 circuit is reduced, so that the current passed through each electromagnetic sheet 17 is increased, and then the magnetic attraction resistance between the electromagnetic sheet 17 and the first permanent magnetic slider 15 is automatically increased, so as to ensure that the auxiliary device can automatically adjust the shock absorption treatment effect based on the vibration condition of the anchor machine.

[0039] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
