Description

Technical Field

[0001] The invention relates to the field of centering installation of ship shaft systems, and in particular to a centering device for installing a stern shaft frame of an electric propulsion shaft. Background Art

[0002] The ship shaft system refers to the general term for the power transmission components from the output end of the main engine or transmission device to the propeller. The components of the shaft system include the propeller, intermediate shaft, thrust shaft, intermediate bearing, thrust bearing, stern shaft frame, etc. The shaft system is located between the main engine and the propeller. The main function of the shaft system is to transmit the power generated by the ship's main engine to the propeller.

[0003] The rear stern shaft bracket is mainly used to hold up and fix the propeller shaft at the stern of the ship. Its overall shape resembles an inverted herringbone, commonly known as the "herringbone". With the continuous development of ship technology, the overall size, tonnage, wall thickness and structural complexity of the rear stern shaft bracket are also increasing. Since the rear stern shaft bracket must be welded to the hull and assembled with the propeller shaft during the later installation, the shape and size requirements of the rear stern shaft bracket are particularly high (the deviation of the welding part shall not exceed 5mm). In order to ensure the stability of the shaft system, it is necessary to make the center line of the stern shaft coincide with the center line of the shaft system as much as possible when installing the stern shaft bracket, so it is difficult to control the size when installing the stern shaft bracket.

[0004] In the prior art, announcement number CN110549109B discloses a stern shaft frame positioning device and positioning method, including a support frame, a left-right moving mechanism, a lifting mechanism, a front-back moving mechanism and a fastening mechanism; the left-right moving mechanism includes a roller arranged at the bottom of the support frame and a first driving member driving the roller to move; the lifting mechanism includes a lifting driving member arranged at the upper part of the support frame, the fixed end of the lifting driving member is fixedly connected to the support frame, and the extended end is connected to the first support plate; the front-back moving mechanism includes a slide rail fixedly arranged on the first support plate and extending in the front-back direction, a second support plate is slidably arranged on the slide rail, and a second driving member driving the second support plate to slide is also arranged between the first support plate and the second support plate; the fastening mechanism is arranged on the second support plate, and the fastening structure is used to fix the stern shaft frame. The positioning device of the present invention can realize the rapid installation of the stern shaft frame.

[0005] The above patent controls the entire upper part to move horizontally on the rails through a left-right moving mechanism. The overall movement is controlled by the motor of the first drive member during the horizontal movement. The stern frame itself has a large weight, which can reach more than ten tons. In addition to the weight of the positioning device, the driving force of the motor in the first drive member is extremely large. The stern frame requires high precision during installation and centering. It can be imagined that the overall horizontal movement directly driven by the first drive member will inevitably lead to poor movement accuracy of the stern frame, which is difficult to meet actual installation requirements. Secondly, the angle adjustment of the stern frame is only adjusted in one direction through three third cylinders, and it is not easy to adjust in other directions, which is inconvenient in actual use.

DETAILED DESCRIPTION

[0035] 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.

[0036] Embodiment 1:

[0037] A device for aligning the stern shaft bracket of an electric propulsion shaft, such as Figure 1As shown, it includes a mobile base 1, a jacking mechanism 2, a micro-pitch adjustment mechanism 3, an inclination adjustment mechanism 4, and a fastening mechanism 5; when in use, the stern shaft frame that needs to be installed in the calibration is hoisted by a crane into the fastening mechanism 5 of the calibration device, and the stern shaft frame is fixed by the fastening mechanism 5, and the fastening mechanism 5 includes support vertical plates fixedly arranged on both sides of the second inclination adjustment plate 23, and the upper end surface of the second inclination adjustment plate 23 is also provided with a support pad, and a clamping plate for clamping and fixing the stern shaft frame is provided between the support vertical plates on both sides; a rail 32 is provided at the bottom of the mobile base 1, and the rail 32 is pre-laid on the stern of the ship in actual use. The mobile base 1 moves on the rail 32 through the rollers arranged at the bottom, and a driving motor for driving the rollers to move is arranged inside the mobile base 1, so that the entire device can be moved or stopped along the rail 32, which is convenient for moving the stern shaft The frame is moved from outside the dock to the stern shaft frame installation position inside the dock; a jacking mechanism 2 is connected to the upper side of the mobile base 1, and the upper structure of the device can be adjusted in height position through the jacking mechanism 2, thereby adjusting the overall height of the stern shaft frame fixed on the top, so that the axis centerline height of the stern shaft frame is close to the centerline of the propulsion shaft system determined by the wire drawing method or the lighting method; specifically, the jacking mechanism 2 includes a plurality of jacking cylinders 31, and the bottom of the jacking cylinders 31 is fixedly arranged on the mobile base 1. As shown in the figure, four jacking cylinders 31 can be arranged at the four corners of the mobile base 1, and the free end of the jacking top is connected to the bottom of the macro adjustment mechanism 3, and the four jacking cylinders 31 need to be driven simultaneously to perform synchronous jacking operations. The use of the jacking cylinders 31 can effectively and accurately adjust the jacking height.

[0038] Embodiment 2:

[0039] Compared with the method of controlling the left and right movement by moving the base 1 in the background art, which has a large error and is not convenient for precise control, the present invention improves and sets a macro adjustment mechanism 3, which is arranged on the upper side of the lifting mechanism 2, such as Figure 2 , Figure 3 As shown, the macro adjustment mechanism 3 has an outer box body, and a partition layer 6 is transversely arranged inside the outer box body, and the partition layer 6 divides the inside of the macro adjustment mechanism 3 into an adjustment chamber 7 and a drive chamber 8; an adjustment disk 9 is arranged through the partition layer 6, and the adjustment disk 9 is rotatably connected to the partition layer 6, and the axis of the bottom of the adjustment disk 9 extends into the drive chamber 8 and is provided with a drive shaft 10, and a fine-tuning disk 15 driven by the adjustment disk 9 is also arranged on the upper side of the outer box body, and a shaft rod 14 is arranged at the bottom of the fine-tuning disk 15, and the shaft rod 14 passes through the reserved hole at the top of the outer box body and is placed in the adjustment slider 13 for rotational connection;

[0040] In actual use, the adjustment disk is only rotated and adjusted in the outer box body, and a power mechanism 11 for driving the adjustment disk 9 to rotate is provided in the driving compartment 8; Figure 6As shown, the power mechanism 11 includes a reduction motor 33, a worm 34, and a worm wheel 35. The worm wheel 35 is fixedly sleeved on the drive shaft 10, and the reduction motor 33 is fixedly arranged in the drive compartment 8. A worm 34 is provided at the output end of the reduction motor 33, and the worm 34 is meshingly connected with the worm wheel 35. When in use, in order to obtain a larger torque and a lower rotation speed of the adjustment disk 9, a worm wheel 35 with a larger diameter can be used, and the reduction motor 33 is used to drive the worm wheel 35 to rotate through the worm 34, that is, the adjustment disk 9 is driven to rotate at a controllable angle.

[0041] like Figure 3 , Figure 5 As shown, the adjusting disk 9 is in the shape of a disk, and an adjusting rail 12 is provided on the adjusting disk 9. The adjusting rail 12 is set in a direction passing through the center of the adjusting disk 9. An adjusting slider 13 is slidably connected in the adjusting rail 12, and a driving mechanism for adjusting the position of the adjusting slider 13 is also provided on the adjusting disk 9; the fine-tuning principle of the present invention is realized by the eccentric setting of the adjusting slider 13. The farther the adjusting slider 13 is from the center of the adjusting disk 9, the greater the moving distance of the driving fine-tuning disk 15 will be; the closer the adjusting slider 13 is to the center of the adjusting disk 9, the smaller the driving moving distance of the driving fine-tuning disk 15 will be, so that the adjustment distance can be controlled; the movement of the adjusting slider 13 is realized by the driving mechanism set in the adjusting rail 12, such as Figure 5 As shown, the driving mechanism includes a driving cylinder 36, one end of the adjusting rail 12 forms a blind end surface in the adjusting disk 9, one end of the driving cylinder 36 is fixedly arranged on the blind end surface, and the other free end is fixedly connected to the adjusting slider 13. When the driving cylinder 36 is extended, the adjusting slider 13 is pushed to move away from the center of the adjusting disk 9, and the fine-tuning moving distance of the fine-tuning disk 15 can be increased.

[0042] If the fine-tuning disk 15 is supported by only one shaft 14, the stability is relatively poor, and the fine-tuning disk 15 may also rotate with the adjustment disk 9, thereby causing the stern shaft frame on the top to rotate, and the effect of fine-tuning the stern shaft frame cannot be achieved. Therefore, a plurality of cross supports 16 are provided between the bottom surface of the fine-tuning disk 15 and the upper end surface of the outer box body. The cross supports 16 are used to form a stable support around the bottom of the fine-tuning disk 15; and secondly, to guide the movement of the fine-tuning disk 15, so that the movement of the fine-tuning disk 15 is translational rather than rotational.

[0043] Specifically, Figure 3 , Figure 4As shown, a plurality of cross supports 16 are arranged around the driving shaft 10 with the driving shaft 10 as the center. The cross support member 16 includes a support plate 17, a horizontal slider 18, and a vertical slider 19. The support plate 17 is horizontally arranged between the gap between the fine-tuning disk 15 and the outer box body. A rolling support structure similar to a universal ball can be arranged on the upper and lower surfaces of the support plate 17 to change the sliding contact between the surfaces into rolling contact to reduce the resistance to movement. The horizontal slider 18 is arranged at the bottom of the support plate 17, and the vertical slider 19 is arranged at the top of the support plate 17. The horizontal slider 18 and the vertical slider 19 are arranged perpendicular to each other in a cross shape. The upper end surface of the outer box body is provided with a rolling support structure similar to the horizontal slider 1 8, the fine-tuning disk 15 is provided with a longitudinal track 21 on the ground that cooperates with the longitudinal slider 19. During actual installation, the transverse slider 18 is inserted into the transverse track 20 on the top surface of the outer box body, and the surface contact can also be preferably changed to rolling contact to reduce friction resistance. Similarly, the longitudinal slider 19 is inserted into the longitudinal track 21 on the bottom surface of the fine-tuning disk 15, so that the fine-tuning disk 15 can be supported and guided by the cross support 16 to perform smooth translation. This structure has a large load-bearing capacity and an adjustable moving distance range, which is convenient for precise adjustment, so that the stern shaft frame is easier to control when it is aligned with the center line of the drive shaft 10.

[0044] Embodiment three:

[0045] Compared with the background technology which can only adjust the angle in one direction, it has great limitations in actual use. The inclination adjustment mechanism 4 of the present device is arranged on the fine-tuning disk 15, including a first inclination adjustment plate 22 and a second inclination adjustment plate 23. As shown in the figure, the adjustment rotation axes of the first inclination adjustment plate 22 and the second inclination adjustment plate 23 are arranged perpendicular to each other, so that the stern shaft frame fixed thereon can realize angle adjustment in both the X-axis and Y-axis directions, so that when the stern shaft frame is installed and centered, its axis can be completely aligned with the center line of the drive shaft 10 system, so as to achieve precise installation and centering.

[0046] Specifically, a first driving member 24 is provided between the first inclination adjustment plate 22 and the fine-tuning disk 15, and a second driving member 25 is provided between the second inclination adjustment plate 23 and the first inclination adjustment plate 22. The first driving member 24 and the second driving member 25 can be controlled by hydraulic cylinders. The first driving member 24 is used to adjust the angle between the first inclination adjustment plate 22 and the fine-tuning disk 15, and the second driving member 25 is used to adjust the angle between the second inclination adjustment plate 23 and the first inclination adjustment plate 22, that is, the angles in two directions are controllable and adjustable; the lower end of the first driving member 24 is hinged to the fine-tuning disk 15, and the upper end is hinged to the first inclination adjustment plate 22; the lower end of the second driving member 25 is hinged to the first inclination adjustment plate 22, and the upper end is hinged to the second inclination adjustment plate 23.

[0047] A first shaft seat 26 is respectively provided at both ends of the middle part of the upper end surface of the fine-tuning disk 15, and first support seats 27 are provided on both sides of the bottom of the first inclination adjustment plate 22. A support shaft 28 is provided on the outer side of the lower end of the first support seat 27, and the support shaft 28 is rotatably connected to the first shaft seat 26. Since the first support seat 27 is arranged at the middle position of the bottom of the first inclination adjustment plate 22, the weight shared on both sides can be relatively balanced, and the first inclination adjustment plate 22 can be driven to flip and rotate with a smaller driving force; similarly, second shaft seats 29 are respectively provided at both ends of the middle part of the upper end surface of the first inclination adjustment disk 9, and second support seats are provided on both sides of the bottom of the second inclination adjustment disk 9. A support shaft 2 30 is provided on the outer side of the second support seat, and the support shaft 2 30 is rotatably connected to the second shaft seat 29; it can be understood that the line connecting the two first support seats 27 and the line connecting the two second support seats should be perpendicular to each other, so as to achieve adjustable angles in two directions.

[0048] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical scheme and inventive concept of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
