Description

TECHNICAL FIELD

[0002] In the manufacturing and installation process of ship products, the installation and positioning of intermediate bearings of a sea valve is a key and complex assembly process. This process requires accurate spatial positioning of the intermediate bearings and their adjusting pads to ensure the normal operation of the subsequent sea valve transmission system. The traditional installation method requires the overall assembly of multiple components such as the T-shaped transmission head, lever, intermediate bearings, adjusting pads, lever, and pull rod of the sea valve, and then the collective positioning. During operation, the preset size of the lever slider needs to be manually adjusted, and the distance between the two intermediate bearings needs to be accurately controlled; then, the adjusting pads of the intermediate bearings are temporarily spot-welded by a welder; after the temporary fixing is completed, the sea valve needs to be tested for opening flexibility, and the opening stroke needs to be measured to verify whether the assembly meets the design requirements.

[0003] Due to the above installation process involving the coordinated positioning, size pre-adjustment, welding, and function testing of multiple heavy components, any error or improper operation at any step may cause the sea valve to be inflexible or the stroke to be insufficient, thereby requiring repeated disassembly, adjustment, and re-spot welding for rework. Such repeated debugging not only has high labor intensity and takes a long time, but also seriously depends on the experience and technology of the operator, often leading to prolonged installation period, waste of human resources, and obstruction to the smooth progress of subsequent processes, affecting the overall production progress and assembly quality.

DETAILED DESCRIPTION

[0021] In order to make the purposes, technical solutions and advantages of the present application clearer, the present application is further described in detail below in combination with the drawings and examples. It should be understood that the specific examples described herein are only used to explain the present application and do not limit the present application.

[0022] Example 1: With reference to Figure 1 and Figure 2 , the present application discloses a positioning tool for intermediate bearings in a sea valve, which is used for pre-adjusting the relative positions of two intermediate bearings 1 to be installed. The top of each of the two intermediate bearings 1 is fixedly connected to a pad plate 4 by a bolt. After the relative position adjustment of the intermediate bearings 1 is completed, the pad plate 4 can be directly connected to the corresponding structure of a ship, thereby realizing the stable and fixed connection of the intermediate bearings 1 and ensuring that the intermediate bearings 1 maintain an accurate relative position with the ship. The positioning tool comprises a base body 2 and an integrated adjustment mechanism 3. Among them: The base body 2 provides a stable mounting platform for the intermediate bearing 1 as the basic structure of the entire tooling, ensuring stability during the adjustment process of the intermediate bearing 1, and preventing shaking or displacement that affects the adjustment accuracy. The base body 2 includes two parallel base plates 22 connected by a connecting piece to form an integral structure. The integrated adjustment mechanism 3 is a key component for realizing the relative position pre-adjustment of the intermediate bearing 1, which can accurately control the distance and horizontal installation angle between the two intermediate bearings 1, thereby meeting the strict requirements of different ship sea valves on the position of the intermediate bearing 1. In actual application, the operator can adjust the two intermediate bearings 1 according to the specific needs of the ship, and through distance and angle adjustment, ensure that the intermediate bearing 1 can perfectly match the sea valve system after being installed on the ship, reducing system failures and operation problems caused by inaccurate installation position. The use of this positioning tool not only improves the installation efficiency of the intermediate bearing 1, but also effectively reduces the error in the installation process, providing a strong guarantee for the long-term stable operation of the ship sea valve system. To adjust the height position of the intermediate bearing 1, the base body 2 is connected to an external lifting mechanism to drive the two intermediate bearings 1 to rise and fall. Specifically, the base body 2 is fixedly connected with a T-shaped transmission connector 5, which is connected with a hydraulic machine to control and adjust the main body of the base plate 22, so that the intermediate bearing 1 moves to the appropriate height.

[0023] Specifically, the base body 2 is provided with two left and right symmetrical bearing mounting portions, and the two intermediate bearings 1 are movably mounted in the corresponding bearing mounting portions. The intermediate bearing 1 can slide and rotate at the bearing mounting portion, thereby facilitating flexible adjustment of the position and angle.

[0024] More specifically, the bearing mounting portion is provided with a horizontally arranged waist-shaped adjustment hole 21 on both sides, and the two waist-shaped adjustment holes 21 are respectively located on the two base plates 22. The rotating shafts of the intermediate bearings 1 are respectively detachably mounted in the two waist-shaped adjustment holes 21, and the rotating shafts of the intermediate bearings 1 can slide horizontally within a certain range, thereby realizing the distance adjustment between the intermediate bearings 1. In this embodiment, the rotating shafts of the intermediate bearings 1 are detachably connected with the waist-shaped adjustment holes 21 through pins or bolts, which not only facilitates the installation and disassembly of the intermediate bearings 1, but also ensures the stability of the intermediate bearings 1 during adjustment.

[0025] Further, the integrated adjusting mechanism 3 is installed on the base body 2 for adjusting the position and spacing of the two intermediate bearings 1, which includes a horizontal spacing adjusting assembly 31 and an angle deflection adjusting assembly 32. The horizontal spacing adjusting assembly 31 drives the two intermediate bearings 1 to slide left and right, thereby adjusting the spacing between the two intermediate bearings 1 to the required appropriate distance; after completing the spacing adjustment, the assembly can also firmly lock the intermediate bearings 1 in the set position to ensure that they do not shift in position during subsequent operations. The angle deflection adjusting assembly 32 drives the two intermediate bearings 1 to rotate to adjust the horizontal installation angle of the intermediate bearings 1 so that they can be adjusted to the appropriate orientation according to actual needs; similarly, after completing the angle adjustment, the assembly also has a locking function to fix the intermediate bearings 1 at the adjusted angle position to ensure their stability. When the intermediate bearings 1 are completed spacing and angle adjustment and locked on the base body 2, the intermediate bearings 1 are detached from the base body 2 by welding the backing plate 4 to the hull, and then the intermediate bearings 1 are installed in the pre-set installation position.

[0026] Further, the horizontal spacing adjusting assembly 31 and the angle deflection adjusting assembly 32 are both provided with two sets, and each bearing mounting portion on the base body 2 is correspondingly provided with a set of horizontal spacing adjusting assembly 31 and angle deflection adjusting assembly 32, which makes each intermediate bearing 1 able to be independently adjusted. The two horizontal spacing adjusting assemblies 31 are respectively used to drive the corresponding intermediate bearings 1 to slide, which not only can accurately adjust the spacing between the two intermediate bearings 1, but also can individually adjust the horizontal position of each intermediate bearing 1 according to actual needs, thereby realizing more flexible and accurate spacing control. The two sets of angle deflection adjusting assemblies 32 also correspond to the two intermediate bearings 1, which can independently drive each intermediate bearing 1 to rotate to adjust its horizontal installation angle, providing greater flexibility for the installation and adjustment of the intermediate bearings 1, so that they can better adapt to different installation environments and work requirements.

[0027] In this embodiment, the horizontal spacing adjusting assembly 31 includes two sets of horizontal driving members 311, which are respectively arranged on both sides of the intermediate bearing 1 to form a bidirectional adjusting capability for the intermediate bearing 1. The horizontal driving member 311 includes a first fixed plate 3111 and a first screw 3112, the first fixed plate 3111 is fixedly connected to the base body 2, specifically, the first fixed plate 3111 can be welded between the two base plates 22, arranged vertically and perpendicular to the two base plates 22, which can serve as a connecting member connecting the two base plates 22, the first screw 3112 is arranged through the first fixed plate 3111 in the horizontal direction, and the first screw 3112 is threadedly connected with the first fixed plate 3111, by rotating the first screw 3112 it can abut against the intermediate bearing 1, and the first screw 3112 can accurately move forward and backward in the horizontal direction when rotating.

[0028] The operator rotates the first screw 3112 to move it in the horizontal direction forward or backward, when the first screw 3112 moves forward, its end gradually abuts against the side of the intermediate bearing 1, by controlling the movement of the first screw 3112, the intermediate bearing 1 can be driven to slide in the horizontal direction, since each side of the intermediate bearing 1 is provided with a set of horizontal driving members 311, after the position of the intermediate bearing 1 is determined, the first screw 3112 on the other side is rotated to make its end abut against the intermediate bearing 1, so as to fix the position of the intermediate bearing 1.

[0029] The angle deflection adjusting assembly 32 comprises a second fixed plate 321 and two second screws 322, the second fixed plate 321 is fixedly connected to one side of the base body 2, the two second screws 322 are vertically arranged in the second fixed plate 321 and are located on the two sides of the intermediate bearing 1, the second screw 322 is threadedly connected with the second fixed plate 321, and the second screw 322 can move up and down in the vertical direction when being rotated, and the top of the second screw 322 can abut against the intermediate bearing 1 by rotating the second screw 322.

[0030] Similarly, the operator rotates the second screw 322 to move it in the vertical direction upward or downward, when the second screw 322 moves upward, its end gradually abuts against the intermediate bearing 1, by controlling the movement of the second screw 322, the intermediate bearing 1 is driven to rotate around its axis, since each side of the intermediate bearing 1 is provided with a set of second screws 322, after the angle of the intermediate bearing 1 is determined, the second screw 322 on the other side is rotated to make its end abut against the intermediate bearing 1, so as to fix the angle of the intermediate bearing 1.

[0031] Embodiment 2: With reference to Figure 3 The difference between the present embodiment and embodiment 1 is that in the present embodiment, the horizontal distance adjusting assembly 31 is only provided in one set, and the horizontal distance adjusting assembly 31 can simultaneously drive the two intermediate bearings 1 to move close to each other or away from each other.

[0032] Specifically, the horizontal distance adjusting assembly 31 comprises a guide limiting piece 312, a bidirectional driving screw 313 and two sliding blocks 314, wherein the guide limiting piece 312 is fixedly connected to the base body 2, the extending direction of the guide limiting piece 312 is parallel to the direction of the line connecting the two intermediate bearings 1, the bidirectional driving screw 313 is rotationally connected to the base body 2 and is parallel to the guide limiting piece 312, the two sliding blocks 314 are threadedly connected with the screw threads of the bidirectional driving screw 313 in opposite directions, and the two sliding blocks 314 are in sliding fit with the guide limiting piece 312, so that the sliding blocks 314 can only move along the extending direction of the guide limiting piece 312; the two sliding blocks 314 are connected with the two intermediate bearings 1 respectively, and a U-shaped sleeve 315 is fixedly connected to each sliding block 314 and is sleeved on the outside of the corresponding intermediate bearing 1, so that when the bidirectional driving screw 313 is rotated, the two sliding blocks 314 and the intermediate bearings 1 can be driven to move closer to or farther away from each other.

[0033] When it is necessary to adjust the distance between the two intermediate bearings 1, the operator rotates the bidirectional driving screw 313 to move the two sliding blocks 314 in opposite directions, and the sliding blocks 314 are connected with the intermediate bearings 1 through the U-shaped sleeves 315, so that the two intermediate bearings 1 can be synchronously moved closer to or farther away from each other, thereby achieving the adjustment of the distance.

[0034] In order to further improve the adjustment efficiency and optimize the structure of the angle deflection adjusting assembly 32, for the angle deflection adjusting assembly 32, a synchronous adjusting structure can be adopted in the embodiment, which comprises a second fixed plate 321, a screw and a push rod. The second fixed plate 321 is fixedly connected to one side of the base body 2, the screw is vertically arranged through the second fixed plate 321 and is threadedly connected with the second fixed plate 321, and is used for locking and fixing one side of the intermediate bearing 1, and the push rod is vertically arranged through the second fixed plate 321, the two push rods are arranged on the side of the two intermediate bearings 1 close to each other, and the two push rods are connected into a whole through a connecting plate, so as to ensure that the two push rods are synchronous during movement. A threaded rod is rotationally connected to the base body 2 in the vertical direction, the threaded rod passes through the connecting plate and is threadedly connected, and the connecting plate and the push rod can be driven to lift by rotating the threaded rod.

[0035] When it is necessary to adjust the angle of the intermediate bearing 1, the connecting plate and the push rod are first driven to lift by rotating the threaded rod, and the top of the push rod abuts against the side surface of the intermediate bearing 1 after lifting, and since the two push rods are connected into a whole through the connecting plate, they can act on the two intermediate bearings 1 at the same time, thereby achieving the synchronous angle adjustment of the two intermediate bearings 1, and then the screw is rotated to abut against the intermediate bearing 1, so as to fix the angle of the intermediate bearing 1.
