Description

Technical Field

[0001] This utility model relates to the field of marine pipeline welding technology, and more specifically, to a marine pipeline welding positioning device. Background Technology

[0002] Marine pipeline welding is a key process in shipbuilding and maintenance, directly affecting the safety, reliability, and service life of ship systems. Ship pipeline systems encompass various media such as fuel oil, lubricating oil, cooling water, seawater, compressed air, steam, and fire fighting. The welding quality must meet the stringent standards of the shipbuilding industry. Publication number CN219837398U relates to the field of pipeline positioning, specifically a pipeline positioning device for welding pipelines. This device includes positioning brackets and a base plate. Two positioning brackets are horizontally arranged and mounted on the base plate. The two positioning brackets are located on the same horizontal plane and face each other. The top end face of the positioning brackets is set as a V-shaped surface, and the projections of the V-shaped surfaces along the horizontal direction coincide. Two pipelines to be welded are horizontally mounted on the V-shaped surfaces of the two positioning brackets. This application achieves alignment between the welding surfaces of the two pipelines by horizontally mounting them on V-shaped surfaces of equal height, avoiding misalignment of the docking ends of the two pipelines.

[0003] However, existing technologies have some problems: existing pipe welding positioning devices require the pipe to be placed on the positioning device for welding. However, when welding pipes on ships, some pipes are located in narrow spaces, and existing positioning devices cannot be placed there. Therefore, we propose a new positioning device for welding pipes on ships. Utility Model Content

[0004] One objective of this invention is to provide a new technical solution for a ship pipeline welding positioning device.

[0005] According to a first aspect of the present invention, a positioning device for welding pipelines on ships is provided, comprising a base, a fixed seat fixedly connected to the base, a first clamp fixedly connected to the fixed seat, a fixed frame rotatably connected to the fixed seat, a fixing component provided on the fixed frame, a second clamp movably connected to the fixed frame, a slide rail provided on the base, a positioning seat slidably connected within the slide rail, a positioning frame rotatably connected to the positioning seat, a locking component provided on the positioning frame, and a positioning component provided on the positioning frame.

[0006] Optionally, the fixing component includes a fixing block, the fixing frame has a groove, the fixing block is slidably connected in the groove, the fixing seat has a slot, and the fixing block is engaged in the slot.

[0007] Optionally, the fixing component further includes a first spring, one end of which is fixedly connected to the inner wall of the groove of the fixing frame, and the other end of which is fixedly connected to the fixing block, on which a pull rod is fixedly connected.

[0008] Optionally, the inner wall of the fixing frame is provided with a sliding groove, and a connecting rod is slidably connected in the sliding groove, and the second clamp is fixedly connected to the connecting rod.

[0009] Optionally, the fixing frame has a threaded hole, and a threaded rod is threadedly connected to the threaded hole. The threaded rod is rotatably connected to the connecting rod, and a throttle handle is fixedly connected to one end of the threaded rod.

[0010] Optionally, the locking component includes a locking block, the positioning frame has a locking groove, the locking block is slidably connected in the locking groove, the positioning seat has a fixing groove, and the locking block is engaged in the locking groove.

[0011] Optionally, the locking assembly further includes a second spring, which is fixedly connected to the inner wall of the locking groove of the positioning seat, and the other end of the second spring is fixedly connected to the locking block, on which a pull ring is fixedly connected.

[0012] Optionally, the positioning component includes two sets of positioning blocks, which are respectively fixedly connected to both sides of the positioning seat, and positioning rods are threadedly connected to the positioning blocks.

[0013] Optionally, the positioning frame is provided with an adjustment groove, an adjustment rod is slidably connected in the adjustment groove, a lead screw is threadedly connected to the positioning frame, the lead screw is rotatably connected to the adjustment rod, a knob is fixedly connected to the lead screw, and a positioning head is fixedly connected to the adjustment rod.

[0014] According to one embodiment of this disclosure, a fixing component is provided, which allows the device to be mounted on the pipe without the need for a support structure, thereby enabling the device to be used in confined environments. After welding is completed, pulling the pull rod causes the fixing block to compress the first spring and move into the groove of the fixing frame, thereby causing the fixing block to disengage from the slot of the fixing seat, and thus allowing the fixing frame and the fixing seat to be separated, thereby quickly removing the device from the welded ship pipe.

[0015] This invention allows the threaded rod to rotate by turning the handle, thereby moving the threaded rod relative to the fixed frame. This causes the threaded rod to slide within the groove of the fixed frame, thus changing the distance between the first clamp and the second clamp, and allowing the device to be fixed on pipes of different sizes.

[0016] This utility model is equipped with a positioning component. First, the positioning seat and positioning frame are moved to a set of ship pipes. Then, by rotating the two sets of positioning rods, the positioning rods are brought into contact with the outer wall of the pipe. Next, the knob is rotated to drive the lead screw to rotate, causing the adjusting rod to move, and thus the positioning head also comes into contact with the outer wall of the ship pipe. At this time, the ship pipe will be subjected to forces in three directions. When the pipe is subjected to three support points, these support points can restrict the six degrees of freedom of the pipe (three translational degrees of freedom and three rotational degrees of freedom), thereby determining the position of the pipe in space. Then, the pipe to be welded is initially aligned with the original pipe. Then, the knob is rotated so that the positioning head is no longer in contact with the pipe. At this time, the positioning seat and positioning frame are moved to move the positioning component to the pipe to be welded. Then, the knob is rotated again so that the positioning head and the two sets of positioning rods position and fix the pipe, avoiding welding deviation.

[0025] Various exemplary embodiments of the present invention will now be described in detail with reference to the accompanying drawings. It should be noted that, unless otherwise specifically stated, the relative arrangement, numerical expressions, and values ​​of the components and steps set forth in these embodiments do not limit the scope of the present invention.

[0026] The following description of at least one exemplary embodiment is merely illustrative and is in no way intended to limit the invention or its application or use.

[0027] Techniques, methods, and equipment known to those skilled in the art may not be discussed in detail, but where appropriate, such techniques, methods, and equipment should be considered part of the specification.

[0028] In all the examples shown and discussed herein, any specific values ​​should be interpreted as merely exemplary and not as limitations. Therefore, other examples of exemplary embodiments may have different values.

[0029] like Figure 1-5 As shown, a ship pipe welding positioning device includes a base 1, which is made of stainless steel and serves to connect and support various components.

[0030] Furthermore, a fixed seat 2 is fixedly connected to the base 1, a first clamp 3 is fixedly connected to the fixed seat 2, a fixed frame 4 is rotatably connected to the fixed seat 2, and a fixed component 5 is provided on the fixed frame 4.

[0031] Specifically, the fixing component 5 includes a fixing block 51, the fixing frame 4 has a groove, the fixing block 51 is slidably connected in the groove, the fixing seat 2 has a slot, and the fixing block 51 is snapped into the slot.

[0032] Furthermore, the fixing component 5 also includes a first spring 52, one end of which is fixedly connected to the inner wall of the groove of the fixing frame 4, and the other end of which is fixedly connected to the fixing block 51, on which a pull rod 53 is fixedly connected.

[0033] Specifically, when welding ship pipelines, the positioning device needs to be fixed on the pipeline first. By rotating the fixing frame 4, the fixing frame 4 drives the fixing block 51 to move. When the fixing block 51 contacts the fixing seat 2, it will be subjected to the force of the fixing seat 2, thereby compressing the first spring 52 and moving into the groove of the fixing frame 4. When the fixing frame 4 and the fixing seat 2 are closed, the fixing block 51 moves to the slot of the fixing seat 2. At this time, the fixing block 51 will be locked in the slot due to the rebound force of the first spring 52, thereby fixing the fixing frame 4 and the fixing seat 2, so that the device can be fitted on the ship pipeline. Then, the device is fixed on the pipeline by the first clamp 3 and the second clamp 6.

[0034] Furthermore, after welding is completed, by pulling the lever 53, the fixing block 51 is driven to compress the first spring 52 and move into the groove of the fixing frame 4, thereby causing the fixing block 51 to disengage from the slot of the fixing seat 2, and thus the fixing frame 4 and the fixing seat 2 can be separated, thereby quickly removing the device from the welded ship pipe.

[0035] Furthermore, a second clamp 6 is movably connected to the fixed frame 4. Both the first clamp 3 and the second clamp 6 are set in a V-shape. When the V-groove contacts the workpiece, the two inclined surfaces are subjected to force at the same time, and the clamping force is symmetrically distributed, which can avoid damage to the pipeline. A sliding groove is opened on the inner wall of the fixed frame 4, and a connecting rod 11 is slidably connected in the sliding groove. The second clamp 6 is fixedly connected to the connecting rod 11.

[0036] Furthermore, the fixing frame 4 has a threaded hole, and a threaded rod 12 is threadedly connected to the threaded hole. The threaded rod 12 is rotatably connected to the connecting rod 11, and a throttle 13 is fixedly connected to one end of the threaded rod 12.

[0037] Specifically, by rotating the throttle 13, the threaded rod 12 is rotated, which in turn causes the threaded rod 12 to move relative to the fixed frame 4. This causes the threaded rod 12 to drive the connecting rod 11 to slide in the groove of the fixed frame 4, thereby changing the distance between the first clamp 3 and the second clamp 6, so that the device can be fixed on pipes of different sizes.

[0038] Furthermore, a slide is provided on the base 1, a positioning seat 7 is slidably connected in the slide, a positioning frame 10 is rotatably connected on the positioning seat 7, and a locking component 8 is provided on the positioning frame 10.

[0039] Specifically, the locking component 8 includes a locking block 81, the positioning frame 10 has a locking groove, the locking block 81 is slidably connected in the locking groove, the positioning seat 7 has a fixing groove, and the locking block 81 is engaged in the locking groove.

[0040] Furthermore, the locking assembly 8 also includes a second spring 82, which is fixedly connected to the inner wall of the locking groove of the positioning seat 7. The other end of the second spring 82 is fixedly connected to the locking block 81, and a pull ring 83 is fixedly connected to the locking block 81.

[0041] Specifically, when positioning the ship's pipeline, the positioning frame 10 is rotated, causing the locking block 81 to move. When the locking block 81 contacts the positioning seat 7, it is subjected to the force of the positioning seat 7, thereby compressing the second spring 82 and moving it into the locking groove of the positioning frame 10. When the positioning frame 10 and the positioning seat 7 are closed, the locking block 81 moves to the fixing groove of the positioning seat 7. At this time, the locking block 81 will be locked in the fixing groove due to the rebound force of the second spring 82, thereby fixing the positioning frame 10 and the positioning seat 7, so that the device can be fitted onto the ship's pipeline. Then, the positioning component 9 is used to position the pipeline.

[0042] Furthermore, after welding is completed, by pulling the pull ring 83, the locking block 81 is driven to compress the second spring 82 and move into the locking groove of the positioning frame 10, so that the locking block 81 is no longer stuck in the fixing groove of the positioning seat 7. At this time, the positioning frame 10 and the positioning seat 7 can be separated, so that the device can be quickly removed from the ship's pipeline.

[0043] Furthermore, a positioning component 9 is provided on the positioning frame 10. The positioning component 9 includes two sets of positioning blocks 91, which are fixedly connected to both sides of the positioning seat 7. A positioning rod 92 is threadedly connected to the positioning block 91.

[0044] Furthermore, the positioning frame 10 is provided with an adjustment groove, and an adjustment rod 93 is slidably connected in the adjustment groove. A lead screw 94 is threadedly connected to the positioning frame 10, and the lead screw 94 is rotatably connected to the adjustment rod 93. A knob 95 is fixedly connected to the lead screw 94, and a positioning head 96 is fixedly connected to the adjustment rod 93.

[0045] Specifically, the positioning seat 7 and positioning frame 10 are first moved to a set of ship pipes. Then, the two sets of positioning rods 92 are rotated to make the positioning rods 92 contact the outer wall of the pipe. Then, the knob 95 is rotated to drive the lead screw 94 to rotate, causing the adjusting rod 93 to move, and thus the positioning head 96 also contacts the outer wall of the ship pipe. At this time, the ship pipe will be subjected to forces in three directions. When the pipe is subjected to three support points, these support points can restrict the six degrees of freedom of the pipe (three translational degrees of freedom and three rotational degrees of freedom), thereby determining the position of the pipe in space. Then, the pipe to be welded is initially aligned with the original pipe. Then, the knob 95 is rotated so that the positioning head 96 no longer contacts the pipe. At this time, the positioning seat 7 and positioning frame 10 are moved to make the positioning component 9 move to the pipe to be welded. Then, the knob 95 is rotated again to make the positioning head 96 and the two sets of positioning rods 92 position and fix the pipe to avoid welding deviation.

[0046] The aforementioned ship pipeline welding positioning device is equipped with a fixing component 5. The fixing component 5 can be used to place the device on the pipeline without the need for a support structure, thus allowing the device to be used in confined environments. After welding is completed, pulling the pull rod 53 causes the fixing block 51 to compress the first spring 52 and move into the groove of the fixing frame 4, thereby causing the fixing block 51 to disengage from the slot of the fixing seat 2, and thus allowing the fixing frame 4 to be separated from the fixing seat 2, thereby quickly removing the device from the welded ship pipeline.

[0047] This invention can rotate the threaded rod 12 by rotating the handle 13, thereby moving the threaded rod 12 relative to the fixed frame 4. This causes the threaded rod 12 to drive the connecting rod 11 to slide in the groove of the fixed frame 4, thereby changing the distance between the first clamp 3 and the second clamp 6, and thus allowing the device to be fixed on pipes of different sizes.

[0048] This utility model is equipped with a positioning component 9. First, the positioning seat 7 and the positioning frame 10 are moved to a set of ship pipes. Then, by rotating the two sets of positioning rods 92, the positioning rods 92 are brought into contact with the outer wall of the pipe. Then, the knob 95 is rotated to drive the lead screw 94 to rotate, causing the adjusting rod 93 to move, and thus the positioning head 96 also comes into contact with the outer wall of the ship pipe. At this time, the ship pipe will be subjected to forces in three directions. When the pipe is subjected to three support points, these support points can restrict the six degrees of freedom of the pipe (three translational degrees of freedom and three rotational degrees of freedom), thereby determining the position of the pipe in space. Then, the pipe to be welded is initially aligned with the original pipe. Then, the knob 95 is rotated so that the positioning head 96 is no longer in contact with the pipe. At this time, the positioning seat 7 and the positioning frame 10 are moved to move the positioning component 9 to the pipe to be welded. Then, the knob 95 is rotated again so that the positioning head 96 and the two sets of positioning rods 92 position and fix the pipe to avoid welding deviation.

Those skilled in the art should understand that modifications can be made to the above embodiments without departing from the scope and spirit of the present invention.
