Description

Technical Field

[0001] The invention relates to the technical field of shipbuilding tooling equipment, in particular to a steel wire pulling frame. Background Art

[0002] With the continuous development of the shipbuilding industry, various new technologies and equipment are constantly being introduced into the shipbuilding process, making the speed of shipbuilding faster and faster. How to improve work efficiency and ensure accuracy is becoming more and more important. When repairing the centerline of a ship's stern tube, it is sometimes necessary to pull a wire to check and measure the coaxiality of the centers of each hole. The conventional method is to cut a hole in the middle of an L50 angle steel, weld an M16 nut, screw an M16 screw with a pre-drilled φ2mm center hole into the nut, and then pass a 0.75mm piano wire into the φ2mm center hole. The screw is tightened to tighten the wire, and the wire is adjusted using the centers of the fore and aft holes as reference points. During adjustment, the angle steel is tapped to achieve up, down, left, and right adjustments. After the wire is positioned, the center deviation of each bearing hole is measured. This tapping adjustment method is not accurate enough and is inconvenient to adjust.

[0003] To address these issues, application number CN201510595378.5 discloses a fixture for cable-pulling axles and rudders in shipbuilding. The fixture comprises a main frame, a support for the cable-pulling axles and rudders, and transverse and longitudinal adjustment mechanisms. The fixture attaches the axis or rudder line to a pulley assembly. By adjusting the pulley and bolts, the axis or rudder line can be precisely adjusted vertically and horizontally, ultimately achieving the ultimate goal of positioning the cable-pulling axles and rudders. This wire pulling tool solves the problem of wire adjustment to a certain extent, but its defects are: it adopts the structure of a pulley assembly to make the wire pass around the pulley. Although the pulley is conducive to the winding and steering of the wire, since the pulley has a certain width, the wire has a large range of movement in its axial direction, resulting in inaccurate lateral adjustment when pulling the wire; secondly, its cross brace and horizontal seat frame are locked and fixed with locking bolts and adjusting bolts, so it does not have temporary adjustment capabilities, and when pulling the wire of the stern tube, it is necessary to hang a counterweight at the end of the wire. When fine-tuning is required, it is useless when hanging a heavier counterweight. It is impossible to remove the bolts safely, so when facing the situation of adjusting the position of the wire, the counterweight must be removed first, and then all the bolts can be loosened before adjustment. At this time, the adjustment has lost its reference, which will undoubtedly increase the difficulty of adjustment and cause the adjustment to be less precise. In addition, since a heavy object is hung at the end of the wire when pulling the wire, and the stern shaft pulling the wire takes a long time, the wire remains straight for a long time and is repeatedly used, which makes it easy for the wire to be broken. In addition, the stern shaft hole will be subjected to operations such as fire, grinding, and cutting, which can easily cause misoperation and breakage of the wire, and then the counterweight at the end of the wire will fall, which can easily cause a safety accident. In view of the above, it is necessary to propose a wire pulling rack to solve the above problems. Summary of the Invention

[0004] The purpose of the present invention is to provide a wire drawing frame in order to solve the above technical problems.

[0006] The longitudinal translation frame is provided with a steel wire threading portion, which includes an upper pressure plate. The upper pressure plate is provided with a through hole for the steel wire to pass through. The upper pressure plate is detachably connected to the longitudinal translation frame. The through hole is provided with a trumpet-shaped expansion hole near one end of the longitudinal translation frame. The lower end of the expansion hole is connected with a hanging hole.

[0008] Furthermore, the transverse translation frame includes a transverse fixed beam and a longitudinal guide rod. Two transverse fixed beams are provided in parallel. Longitudinal guide rods are fixed at both ends of the two transverse fixed beams. The transverse fixed beams and the longitudinal guide rods form a rectangular frame. The spacing between the transverse fixed beams on both sides is the same as the spacing between the transverse guide rods, and the width of the transverse fixed beam is smaller than the length of the longitudinal guide rod.

[0012] Furthermore, the safety lock structure is arranged in the upper pressure plate, including a screw-shaped card block, a torsion spring, and an insert plate.

[0030] The technical solutions in the embodiments of the present invention will be clearly and completely described 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.

[0031] Example 1:

[0032] A wire drawing frame, comprising a fixed frame 1, such as Figure 1 As shown, in actual use, fixing frames 29 are welded on the hulls on both sides of the stern tube, and the fixing frame 1 of the wire pulling fixture is fixed on the fixing frames 29. Specifically, welding or bolts can be used for fixing connection, and then the two ends of the steel wire are set on the wire pulling frame between the two fixing frames 29 to ensure that the adjustment range of the steel wire is within the use range. The specified counterweight 30 is hung on one end of the steel wire, and the steel wire is adjusted through the fixture to pass through the reference center to determine the concentricity of each center hole of the stern shaft.

[0033] Specifically, such as Figure 2The three views of the tool are shown. The fixed frame 1 is provided with a transverse translation frame and a longitudinal translation frame 5. The longitudinal translation frame 5 is provided with a wire threading part 2. The wire threading part 2 includes an upper pressing plate 3. Figure 2 As shown, both sides of the upper pressing plate 3 are fixed to the longitudinal translation frame 5 by screws, that is, when the longitudinal translation frame 5 moves, the wire threading part 2 can be controlled to move synchronously, thereby adjusting the wire laterally or longitudinally, and the wire threading part 2 is a screw-type detachable design, which can be easily disassembled when replacing the wire, and after replacing the wire, since the position of the longitudinal translation frame 5 does not move, the original reference point does not move, and the adjustment can be continued on the original basis after replacing the wire, as shown in FIG. Figure 6 As shown, the upper pressing plate 3 is provided with a through hole 4 for the steel wire to pass through, and the upper pressing plate 3 is detachably connected to the longitudinal translation frame 5 by a screw, and the through hole 4 is provided with a trumpet-shaped expansion hole 6 at one end close to the longitudinal translation frame 5, and the lower end of the expansion hole 6 is connected with a hanging hole 7; in actual use, after the upper pressing plate 3 is removed, the steel wire is passed through the outer end of the through hole 4, passes through the expansion hole 6 and then turns downward to pass out, and the upper pressing plate 3 is fixed to the longitudinal translation frame 5 using a screw, and a counterweight 30 is tied to the lower end of the steel wire. The designed expansion hole 6 has a trumpet-shaped smooth transition surface, so the steel wire will not wear the surface when pulled, which is beneficial to protecting the steel wire.

[0034] The lateral translation frame is slidably connected to the fixed frame 1. The fixed frame 1 is provided with a first fine-tuning portion that drives the lateral translation frame to translate horizontally. The lateral translation frame can slide horizontally in the fixed frame 1 under the control of the first fine-tuning portion. Specifically, Figure 2 、 Figure 3 、 Figure 4 、 Figure 5 、 Figure 6 As shown, the fixed frame 1 includes a longitudinal fixed beam 8 and a transverse guide rod 9; two longitudinal fixed beams 8 are provided in parallel, and a transverse guide rod 9 is fixed on the upper and lower sides between the two longitudinal fixed beams 8, so that the side fixed frame 29 and the transverse guide rod 9 form a rectangular fixed frame 1, and the transverse guide rod 9 serves as the sliding connection basis of the transverse translation frame, so that the transverse translation frame can move freely laterally in the fixed frame 1.

[0035] The transverse translation frame includes two parallel transverse fixed beams 10 and longitudinal guide rods 11. The longitudinal guide rods 11 are fixed to both ends of the two transverse fixed beams 10, forming a rectangular frame. The spacing between the transverse fixed beams 10 on both sides is the same as the spacing between the transverse guide rods 9, and the width of the transverse fixed beams 10 is less than the length of the longitudinal guide rods 11. A second sliding sleeve 13 is fixed to the transverse fixed beam 10 and slidably sleeved on the transverse guide rod 9. The provision of the two second sliding sleeves 13 allows the upper and lower ends of the transverse translation frame to be slidably connected to the fixed frame 1. The first fine-tuning portion includes a transverse screw 16, and the longitudinal fixed beam 8 is penetrated by a long strip hole 17. The two ends of the transverse screw 16 pass through the long strip holes 17 on both sides, and a limiting cap 18 larger than the width of the long strip hole 17 is provided at both ends. The setting of the limiting cap 18 can make the transverse screw 16 rotate in the long strip hole. When rotating, the limiting cap 18 can limit the axial movement of the transverse screw 16, so that the transverse screw 16 can rotate freely; and the transverse screw 16 is not restricted when moving in the vertical direction in the long strip hole 17. In order to utilize the rotation torque of the transverse screw 16 to drive the transverse plane The moving frame and the longitudinal translation frame 5 move laterally. A transverse screw hole 15 is provided on the longitudinal translation frame 5, so that the transverse screw 16 is threadedly connected to the transverse screw hole 15. Therefore, when the transverse screw 16 is rotated, the longitudinal translation frame 5 can be pushed to move laterally. The longitudinal translation frame 5 is installed on the transverse translation frame, and the transverse translation frame and the longitudinal translation frame 5 can be driven together to adjust the transverse movement. Since the thread adjustment of the screw is used in this adjustment, bidirectional fine adjustment can be achieved, and based on the unidirectionality of the thread transmission, the longitudinal translation frame 5 will not reversely drive the transverse screw 16 to rotate, and has the self-locking ability of transverse movement.

[0036] Furthermore, the longitudinal translation frame 5 is slidably connected to the transverse translation frame. The longitudinal translation frame 5 can only be raised and lowered longitudinally on the transverse translation frame. The longitudinal translation frame 5 is provided with a second fine-tuning portion that drives the longitudinal translation frame 5 in longitudinal translation. The second fine-tuning portion includes a longitudinal screw 19, which is rotatably connected and disposed between the two transverse fixed beams 10. The longitudinal screw 19 is threadedly engaged with longitudinal screw holes 14. Both ends of the longitudinal screw 19 extend through the transverse fixed beams 10 and are provided with drive caps 20 on the outside. The longitudinal translation frame 5 is provided with longitudinal screw holes 14. The drive method used is similar to that achieved by the transverse screw 16 and the transverse screw hole 15. The rotational torque of the longitudinal screw 19 is converted through the longitudinal screw 19 into the driving force that drives the longitudinal translation frame 5 up and down.

[0037] Example 2:

[0038] During the production or maintenance of a ship, the ship is fixed in the dock and the stern tube is at a certain height from the ground. When the counterweight 30 is suspended by a steel wire, the counterweight 30 may fall due to repeated use of the steel wire or if the steel wire is broken during the construction of the stern tube, thereby causing a safety accident. To solve this problem, the present steel wire pulling tool is provided with a safety lock structure for locking the steel wire in the steel wire threading portion 2. Specifically, Figure 7 As shown, the safety lock structure is arranged in the upper pressure plate 3, including a screw block 21, a torsion spring, and a plug plate 22. The same as the first embodiment is that the upper pressure plate 3 is also connected to the longitudinal translation frame 5 by a detachable connection. The difference is that, as shown in FIG. Figure 8 As shown, a mounting cavity 23 is provided in the upper pressure plate 3, and the spiral block 21 is rotatably connected and arranged in the mounting cavity 23. The spiral block 21 has a locking side wall 27 with a gradually increasing radius. The spiral curve of the spiral block 21 can adopt a shape similar to a Fibonacci spiral. The side of the mounting cavity 23 close to the through hole 4 is connected to the through hole 4. It can be understood that when the spiral block 21 rotates in the mounting cavity 23, it can lock the steel wire in the through hole 4, and this effect is used to prevent danger after the steel wire breaks.

[0039] The vertical screw block 21 is fixed with a rotating shaft 24. The screw block 21 is rotatably connected to the upper pressure plate 3 via the rotating shaft 24. One end of the rotating shaft 24 extends outward from the upper pressure plate 3. When in use, the rotating position of the screw block 21 can be controlled from the outside by rotating the end of the rotating shaft 24 extending outward, so as to reset the screw block 21. Furthermore, the inserting plate 22 is inserted into the mounting cavity 23 from the side of the upper pressure plate 3. Figure 10 As shown, the screw-shaped block 21 is further provided with a slot 25, and when the inserting plate 22 is inserted into the installation cavity 23, it can be inserted into the slot 25. Figure 8 The figure shows the state of the plug plate 22 inserted into the slot 25. At this time, the plug plate 22 can limit the screw block 21 and restrict its rotation. As shown in the figure, the larger radius part of the screw block 21 does not enter the through hole 4, that is, the locking side wall 27 is located outside the through hole 4, and this state is set to the first preset position. At this time, when it is used to thread the steel wire or the steel wire needs to be repeatedly pulled and moved during installation, the movement of the steel wire is not restricted because the locking side wall 27 does not contact and squeeze the steel wire; further, when the steel wire is installed and enters the fine-tuning stage, in order to prevent the counterweight 30 from breaking in the middle of the steel wire and falling off, the steel wire needs to be locked at this time. Specifically, in this embodiment, a notch 32 is provided on the side of the plug plate 22 close to the screw block 21, the width of the notch 32 is not less than the thickness of the screw block 21, and the side of the notch 32 is a locking portion 26 that cooperates with the slot 25; Figure 9As shown, when the insert plate 22 is pulled outward to align the notch 32 with the screw block 21, the screw block 21 is unlocked. Under the action of the torsion spring, the screw block 21 rotates clockwise. At this time, the locking side wall 27 rotates into the through hole 4, thereby squeezing the steel wire to fix it. When the notch 32 is aligned with the screw block 21, the screw block 21 is unlocked, the torsion spring drives the screw block 21 to rotate, and the locking side wall 27 is stuck in the through hole 4 to the second preset position. Under the action of the torsion spring, the spiral block 21 is rotated from the first preset position to the second preset position to fix the steel wire. It can be understood that one end of the counterweight 30 is set to the end of the expansion hole 6. If the middle of the steel wire breaks, the steel wire will be pulled to the left, and the spiral block 21 will be driven to rotate further counterclockwise. Since the radius of the spiral block 21 is gradually increased, its extrusion and locking force on the steel wire increases accordingly, thereby ensuring the locking of the steel wire. When the steel wire is pulled to the right, the spiral block 21 is pulled to rotate, and the radius gradually decreases when rotating counterclockwise, and the steel wire will not be locked. The advantage of this structure is that it prevents the counterweight 30 from falling when the steel wire moves to the left without hindering the adjustment of the steel wire to the right. In actual use, after the steel wire is erected, the plug plate 22 can be pulled outward in the fine-tuning stage to lock the steel wire as described above, thereby preventing the counterweight 30 from falling.

[0040] On the contrary, when it is necessary to remove the steel wire, the rotating shaft 24 can be rotated counterclockwise, and the insert plate 22 can be inserted to lock the screw card again. At this time, the through hole 4 is unobstructed, which is convenient for operations such as replacing the steel wire. Figure 10 As shown, the locking side wall 27 is configured as a serrated tooth surface 28 , which has a better anti-slip effect on the steel wire.

[0041] The above description is only a preferred specific embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any technician familiar with the technical field, within the technical scope disclosed by the present invention, who makes equivalent replacements or changes based on the technical solution and inventive concept of the present invention, should be covered by the scope of protection of the present invention.
