[0030] Please refer to Figures 1-3The embodiment of the present application provides a sea valve frame positioning tool 100, which is applied to a ship body 1. The ship body 1 comprises an inner plate 10, an outer plate 20 and a cup-shaped pipe joint 30. The inner plate 10 is located above the outer plate 20. The cup-shaped pipe joint 30 is arranged on the inner plate 10. The outer plate 20 is provided with a mounting area for mounting a sea valve frame 40. The cup-shaped pipe joint 30 is arranged in correspondence with the mounting area. The sea valve frame positioning tool 100 provided by the embodiment of the present application can position the sea valve frame 40, so that the mounting position of the sea valve frame 40 is accurate, and thus a connecting rod mechanism can be arranged in the cup-shaped pipe joint 30 to connect a hydraulic machine and the sea valve, so as to ensure that an operator can normally control the opening and closing of the sea valve.

[0031] In the embodiment of the present application, the sea valve frame positioning tool 100 comprises a main body 110 and a positioning piece 120. The main body 110 is mounted on a pipe opening of the cup-shaped pipe joint 30. The positioning piece 120 is mounted on the main body 110, and a central axis of the positioning piece 120 coincides with a central axis of the cup-shaped pipe joint 30. The positioning piece 120 has a positioning reference point in the mounting area, which coincides with the central axis of the cup-shaped pipe joint 30, so as to position the sea valve frame 40.

[0032] It should be noted that four sea valves are arranged on the sea valve frame 40. The positions of the sea valves on the sea valve frame 40 are fixed (determined according to design drawings), so that as long as the position of the sea valve frame 40 is accurate, the positions of the sea valves are accurate, and thus the connecting rod structure can pass through the cup-shaped pipe joint 30 to connect the hydraulic machine and the sea valve, so as to control the opening and closing of the sea valve.

[0033] Since the ultimate purpose of positioning the sea valve frame 40 is to make the positions of the sea valves accurate, so that the connecting rod structure passing through the cup-shaped pipe joint 30 can be connected to the sea valve, the central axis of the cup-shaped pipe joint 30 is used as a positioning reference to position the sea valve frame 40. Specifically, a reference point can be arranged on the sea valve frame 40 according to the design drawings. When the reference point coincides with the central axis of the cup-shaped pipe joint 30, the mounting position of the sea valve frame 40 is accurate.

[0034] Next, the mounting method of the sea valve frame 40 by the positioning tool 100 provided by the embodiment of the present application will be described.

[0035] 1. The sea valve frame 40 is hoisted to a mounting height by a hoist. The sea valve frame 40 enters the mounting area of the outer plate 20 from below by the hoist, that is, the initial position of the sea valve frame 40 is below the outer plate 20.

[0036] 2. The positioning tool 100 is mounted on the pipe opening of the cup-shaped pipe joint 30.

[0037] 3. Slowly move the sea valve frame 40 according to the positioning reference point in the installation area, adjust the installation height and the front and back and left and right positions, so that the reference point on the sea valve frame 40 coincides with the positioning reference point, and the outer edge of the sea valve frame 40 is flush with the outer plate 20;

[0038] 4. After the sea valve frame 40 is adjusted to the position, spot weld the sea valve frame 40 to the outer plate 20, and at any time observe whether the position of the reference point and the positioning reference point changes, if there is a change, repeat the above step 4 until the spot welding is firm.

[0039] Since the positioning reference point coincides with the center axis of the cup-shaped pipe joint 30, the reference point of the sea valve frame 40 coincides with the positioning reference point, and the reference point of the sea valve frame 40 coincides with the center axis of the cup-shaped pipe joint 30, so that the position of the sea valve frame 40 is accurate.

[0040] It needs to be explained that before the sea valve frame 40 is hoisted to the installation area of the outer plate 20, the positioning reference point of the positioning member 120 is located in the installation area, and when the sea valve frame 40 enters the installation area, the positioning reference point can be located on the sea valve frame 40, so that the position of the sea valve frame 40 can be adjusted according to the positioning reference point, so that the positioning reference point coincides with the reference point.

[0041] The sea valve frame positioning tool 100 provided in the application, since the positioning member 120 has a positioning reference point coinciding with the center axis of the cup-shaped pipe joint 30 in the installation area, when the sea valve frame 40 is installed, it can be installed on the positioning tool 100 on the pipe opening of the cup-shaped pipe joint 30, and the sea valve frame 40 is positioned according to the positioning reference point, so that the installation position of the sea valve frame 40 is accurate, so that the connecting rod mechanism can be arranged in the cup-shaped pipe joint 30 to connect the hydraulic machine and the sea valve, and the operator can normally control the opening and closing of the sea valve as much as possible.

[0042] In some embodiments, the positioning member 120 is a laser emitter, and the focal point of the positioning member 120 in the installation area is the positioning reference point.

[0043] The laser emitter can emit laser, so as to form a focal point in the installation area, and the focal point is configured as the positioning reference point. When the sea valve frame 40 enters the installation area, the focal point will be formed on the sea valve frame 40, so that the position of the sea valve frame 40 can be adjusted according to the positioning reference point, so that the positioning reference point coincides with the reference point, and the focal length of the laser can be adjusted at any time as needed.

[0044] Specifically, the laser emitter is rechargeable, the beam is emitted vertically from the center position of the head, and the tail has a switch and a focusing knob for controlling and adjusting the laser light source.

[0045] In some embodiments, the positioning member 120 is a positioning shaft, which extends into the installation area, and the end of the positioning member 120 located in the installation area is the positioning reference point.

[0046] The positioning member 120 can also be a positioning shaft, which extends downward from the main body 110 into the installation area, and can be regarded as extending the central axis of the cup-shaped pipe joint 30 into the installation area. Therefore, the end of the positioning member 120 located in the installation area can be configured as the positioning reference point, so that the positioning tool 100 can be conveniently positioned relative to the sea valve frame 40.

[0047] When the sea valve frame 40 enters the installation area, the end of the positioning shaft can contact the sea valve frame 40, so that the position of the sea valve frame 40 can be adjusted according to the positioning shaft. When the reference point coincides with the end of the positioning shaft, the reference point coincides with the central axis of the cup-shaped pipe joint 30, and the position of the sea valve frame 40 is accurate.

[0048] In some embodiments, the main body 110 is provided with an installation opening 111, the central axis of the installation opening 111 coincides with the central axis of the cup-shaped pipe joint 30, and the positioning member 120 is installed in the installation opening 111.

[0049] Since the central axis of the installation opening 111 coincides with the central axis of the cup-shaped pipe joint 30, and the positioning member 120 is installed in the installation opening 111, the central axis of the positioning member 120 also coincides with the central axis of the cup-shaped pipe joint 30. Specifically, the installation opening 111 is located at the center of the main body 110.

[0050] When the positioning member 120 is a laser emitter, in order to stably install the laser emitter in the installation opening 111, an external thread can be provided on the laser emitter, and an internal thread is provided on the inner wall of the installation opening 111. The laser emitter is screwed with the installation opening 111 to facilitate the installation and removal of the laser emitter. When the positioning member 120 is a positioning shaft, the positioning shaft is directly inserted into the installation opening 111.

[0051] Specifically, the inner wall of the installation opening 111 is provided with a chamfer 111a to facilitate the installation of the positioning member 120 into the installation opening 111.

[0052] In some embodiments, the main body 110 is arranged on the side of the cup-shaped pipe joint 30 away from the outer plate 20.

[0053] Since the inner plate 10 is located above the outer plate 20, the main body 110 is arranged on the side of the cup-shaped pipe joint 30 away from the outer plate 20, i.e. the main body 110 is arranged on the upper end of the cup-shaped pipe joint 30, so that the worker can conveniently install the positioning tool 100 into the pipe joint of the cup-shaped pipe joint 30. Specifically, the main body 110 can be connected with the cup-shaped joint by a flange 113.

[0054] Of course, in other embodiments, the main body 110 can also be arranged at the lower end of the cup-shaped pipe joint 30, and no limitation is made in this regard.

[0055] In some embodiments, the main body 110 is provided with a positioning protrusion, and the cup-shaped pipe joint 30 is provided with a positioning groove 31, and the positioning protrusion is clamped in the positioning groove 31.

[0056] In order to ensure that the installation position of the main body 110 on the cup-shaped pipe joint 30 is accurate, so that the central axis of the installation port 111 coincides with the central axis of the cup-shaped pipe joint 30, the main body 110 also needs to be positioned when the main body 110 is installed. Since the main body 110 is provided with a positioning protrusion, and the cup-shaped pipe joint 30 is provided with a positioning groove 31, and the positioning protrusion is clamped in the positioning groove 31, that is, when the main body 110 is installed, the positioning protrusion is clamped in the positioning groove 31, so that the installation position of the main body 110 is accurate.

[0057] Specifically, the positioning protrusion and the positioning groove 31 can be annular to increase the clamping area between the positioning protrusion and the positioning groove 31, thereby improving the positioning accuracy. And the positioning protrusion is arranged around the installation port 111, so that the clamping cooperation between the positioning protrusion and the positioning groove 31 does not interfere with the installation of the positioning member 120 between the installation ports 111.

Therefore, the appended claims are intended to be interpreted as including all changes and modifications falling within the scope of the present application.

[0059] Obviously, those skilled in the art can make various modifications and variations to the present application without departing from the spirit and scope of the present application. Thus, if these modifications and variations of the present application fall within the scope of the claims of the present application and their equivalents, the present application also intends to include these modifications and variations.
