Description

Technical Field

[0001] This utility model relates to the field of shipbuilding technology, and in particular to a positioning fixture for an infrared suppressor. Background Technology

[0002] During shipbuilding, each vessel is equipped with at least two gas turbine infrared suppressors to suppress infrared radiation signals from the gas turbines. In existing technology, the installation of the infrared suppressors onto the base requires alignment. This alignment is achieved by using a long iron bar to pry the suppressor, moving it to the required position. This method is unprofessional, time-consuming, and labor-intensive, and it's difficult to guarantee the accuracy of the movement. Furthermore, the prying process can damage the suppressor itself. Additionally, workers standing on a 20-meter-high open deck while prying the suppressors face a risk of falling.

[0003] Therefore, a positioning fixture is needed to assist in the alignment process between the infrared suppressor and the base. Utility Model Content

[0004] In view of the shortcomings of the prior art described above, the present invention provides a positioning fixture for an infrared suppressor. The positioning fixture includes a base, on the upper surface of the base a square block is placed, and four support bolts are arranged evenly along the circumference on the outer edge of the base. The four support bolts are all horizontally arranged and respectively abut against the four side walls of the square block, thereby adjusting the front-back and left-right positions of the square block through the support bolts.

[0005] An L-shaped locking plate is fixedly connected to the outer side wall of the base. The locking plate includes a first horizontal part and a first vertical part. The first horizontal part is located on the same plane as the base, and the upper end of the first vertical part is perpendicularly connected to the end of the first horizontal part away from the base. A reinforcing plate is fixed to the lower surface of the base, and an accommodating gap is formed between the reinforcing plate and the first vertical part. The base is placed on a base, which includes an annular plate and an arc-shaped vertical plate fixed to the inner edge of the annular plate. The reinforcing plate contacts the annular plate, and the accommodating gap clamps the arc-shaped vertical plate to fix the base.

[0006] The positioning fixture also includes a bracket, the bottom of which is connected to a square block, and the upper part of which is connected to the outer wall of an infrared suppressor. The base surrounds the cylindrical infrared suppressor, and the relative position of the infrared suppressor and the base is adjusted by moving the position of the square block to achieve centering.

[0007] Optionally, the base is square, and positioning blocks are fixed to all four outer edges of the base. Four support bolts pass through the four positioning blocks and are connected by a spiral surface.

[0008] Optionally, the cross-section of the reinforcing plate is H-shaped. The reinforcing plate includes two parallel first vertical plates and a second vertical plate connecting the two first vertical plates. The first vertical plates are perpendicular to the first vertical part of the locking plate, and the second vertical plate is parallel to the first vertical part of the locking plate. An accommodating gap is formed between the ends of the two first vertical plates facing the first vertical part and the first vertical part.

[0009] Optionally, a locking bolt passes through the vertical part of the locking plate, and the locking bolt abuts against the inner surface of the arc-shaped vertical plate away from the annular flat plate to achieve fixation.

[0010] Optionally, the bracket includes an L-shaped connecting plate, which includes a second vertical part and a second horizontal part. The lower end of the second horizontal part is vertically connected to the lower end of the second vertical part. A vertical sleeve is fixed to the end of the second horizontal part away from the second vertical part. A lead screw passes vertically through the vertical sleeve, and the lower end of the lead screw is located in a groove on the upper surface of the square block. The lead screw is threadedly connected to the vertical sleeve to adjust the relative height between the connecting plate and the square block.

[0011] Optionally, a self-locking nut is fitted on the lower section of the lead screw located below the vertical sleeve, so that the lead screw can be locked in place after the height is adjusted.

[0012] Optionally, a through hole is provided at the upper end of the second vertical part, and a vertical support plate arranged in a radial direction is fixed on the outer wall of the infrared suppressor. The through hole and the vertical support plate are connected by a first fixing bolt, which is arranged parallel to the second horizontal part.

[0013] Optionally, a U-shaped clamping member is fixed in the middle of the second vertical part. The opening of the clamping member faces the infrared suppressor and clamps the outer edge of the vertical support plate away from the infrared suppressor. The clamping member is equipped with a second fixing bolt, which abuts against the surface of the vertical support plate to achieve auxiliary fixation.

[0014] As described above, this utility model provides a positioning fixture for an infrared suppressor, including a base and a bracket. A square block is placed on the upper surface of the base, and four support bolts are tightened against the four side walls of the square block, thereby adjusting the front-back, left-right, and right-side positions of the square block through the support bolts. An L-shaped locking plate is fixedly connected to the outer side wall of the base, fixing the base to the arc-shaped vertical plate of the base. The bottom of the bracket is connected to the square block, and the upper part of the bracket is connected to the outer side wall of the infrared suppressor. By moving the position of the square block, the relative position of the infrared suppressor and the base is adjusted to achieve centering, and the amount of movement can be precisely controlled. This positioning fixture, through the combination of the base and the bracket, uses bolts to fix the fixture to the infrared suppressor, achieving auxiliary positioning for infrared suppression. The application of this positioning method effectively eliminates damage to equipment caused by rough construction such as prying, pushing, and smashing, while also improving installation quality and personnel safety.

[0015] Furthermore, this positioning fixture is inexpensive and easy to manufacture, which not only improves the installation quality of infrared suppressors but also increases work efficiency. Since it is reusable and does not suffer wear and tear during use, it significantly reduces expenses, achieves energy conservation and emission reduction, and shortens the construction cycle.

[0028] Example 1

[0029] like Figures 1 to 5 As shown, this embodiment provides a positioning fixture for an infrared suppressor, the positioning fixture including:

[0030] A base 11 has a square block 5 placed on its upper surface. Four support bolts 6 are evenly arranged circumferentially along the outer edge of the base 11. These four support bolts 6 are horizontally positioned and abut against the four side walls of the square block 5, allowing adjustment of the block's position in all directions. The base 11 is square, and positioning blocks are fixed to its four outer edges. The four support bolts 6 pass through the four positioning blocks and are connected by a helical surface.

[0031] An L-shaped locking plate 8 is fixedly connected to the outer side wall of the base 11. The locking plate 8 includes a first horizontal part 81 and a first vertical part 82. The first horizontal part 81 is located on the same plane as the base 11, and the upper end of the first vertical part 82 is perpendicularly connected to the end of the first horizontal part 81 away from the base 11.

[0032] The lower surface of the base 11 is fixed with a reinforcing plate 10 with an H-shaped cross-section. The reinforcing plate 10 includes two parallel first vertical plates 101 and a second vertical plate 102 connecting the two first vertical plates 101. The first vertical plates 101 are perpendicular to the first vertical portion 82 of the locking plate 8, and the second vertical plate 102 is parallel to the first vertical portion 82 of the locking plate 8. An accommodating gap is formed between the ends of the two first vertical plates 101 facing the first vertical portion 82 and the first vertical portion 82.

[0033] The base 11 is placed on the base 20. The base 20 includes an annular plate 21 and an arc-shaped vertical plate 22 fixed to the inner edge of the annular plate 21. The reinforcing plate 10 contacts the annular plate 21, and the accommodating gap clamps the arc-shaped vertical plate 22 to fix the base 11. The vertical part of the locking plate 8 is penetrated by a locking bolt 7, and the locking bolt 7 abuts against the inner surface of the arc-shaped vertical plate 22 away from the annular plate 21 to fix it.

[0034] Furthermore, the positioning fixture also includes a bracket 12, the bottom of which is connected to the square block 5, and the upper part of which is connected to the outer wall of the infrared suppressor 30. The base 20 surrounds the cylindrical infrared suppressor 30, and the relative position of the infrared suppressor 30 and the base 20 is adjusted by moving the position of the square block 5 to achieve centering.

[0035] Furthermore, the bracket 12 includes an L-shaped connecting plate, which includes a second vertical portion and a second horizontal portion. The lower end of the second horizontal portion is vertically connected to the lower end of the second vertical portion. A vertical sleeve 4 is fixed to the end of the second horizontal portion away from the second vertical portion. A lead screw 3 vertically passes through the vertical sleeve 4, and the lower end of the lead screw 3 is located in a groove on the upper surface of the square block 5. The lead screw 3 is threadedly connected to the vertical sleeve 4 to adjust the relative height between the connecting plate and the square block 5. A self-locking nut 9 is fitted on the lower segment of the lead screw 3 below the vertical sleeve 4. After the height is adjusted to the correct position, the lead screw 3 is locked by the self-locking nut 9, thereby fixing the relative height between the infrared suppressor 30 and the base 20 and preventing the center from shifting away.

[0036] The upper end of the second vertical part is provided with a through hole, and the outer wall of the infrared suppressor 30 is fixed with a vertical support plate 31 arranged in the radial direction. The through hole and the vertical support plate are connected by a first fixing bolt 1, which is arranged parallel to the second horizontal part.

[0037] A U-shaped clamping member is fixed in the middle of the second vertical part. The opening of the clamping member faces the infrared suppressor 30 and clamps the outer edge of the vertical support plate 31 away from the infrared suppressor. The clamping member is equipped with a second fixing bolt 2, which abuts against the surface of the vertical support plate to achieve auxiliary fixation.

[0038] The specific steps for using the above positioning fixture are as follows:

[0039] The bracket 12 is mounted on the infrared suppressor by the first fixing bolt 1, and the second fixing bolt 2 is tightened to further strengthen the bracket 12.

[0040] Tighten the lead screw 3 downwards to the appropriate height and then install the base 11. Place the base 11 directly below the lead screw 3 and adjust its position so that the lowest point of the lead screw 3 can fall onto the square block 5 on the base 11. At the same time, adjust the locking bolts 7 on the locking plate 8 to firmly fix the base 11 to the base 20 of the deck. Then, adjust the position of the square block 5 by using the four support bolts 6 at the front, back, left and rear to change the relative position of the infrared suppressor and the base. This allows for precise control of the amount of movement. During the process, the relative height of the infrared suppressor and the base is adjusted by the lead screw 3, ultimately achieving the centering effect of the infrared suppressor of this invention.

[0041] In summary, this utility model provides a positioning fixture for an infrared suppressor, including a base and a support. A square block is placed on the upper surface of the base, and four support bolts are tightened against the four side walls of the square block, thereby adjusting the front-back, left-right, and right-side positions of the square block through the support bolts. An L-shaped locking plate is fixedly connected to the outer side wall of the base, fixing the base to the arc-shaped vertical plate of the base. The bottom of the support is connected to the square block, and the upper part of the support is connected to the outer side wall of the infrared suppressor. By moving the position of the square block, the relative position of the infrared suppressor and the base is adjusted to achieve centering, and the amount of movement can be precisely controlled. This positioning fixture, through the combination of the base and the support, uses bolts to fix the fixture to the infrared suppressor, achieving auxiliary positioning for infrared suppression. The application of this positioning method effectively eliminates damage to equipment caused by rough construction such as prying, pushing, and smashing, while also improving installation quality and personnel safety.

[0042] The above embodiments are merely illustrative of the principles and effects of this utility model and are not intended to limit the scope of this utility model. Any person skilled in the art can modify or alter the above embodiments without departing from the spirit and scope of this utility model. Therefore, all equivalent modifications or alterations made by those skilled in the art without departing from the spirit and technical concept disclosed in this utility model should still be covered by the claims of this utility model.
