Description

Technical Field

[0001] The utility model relates to the technical field of shipbuilding, in particular to an adjustable pull rod. Background Art

[0002] In the shipbuilding industry, steel plates or profiles of varying heights need to be fixed during positioning and assembly operations involving flat and curved surfaces. The traditional method involves first moving the profile to the required position, then welding the profile to secure it, and finally completing the work.

[0003] The main problems with this construction method are: weld scars; difficulty in grinding and repairing welding; and easy damage to profiles. Summary of the Invention

[0004] In order to overcome the shortcomings of the prior art and avoid welding, a profile positioning tool with high work efficiency, no damage to profiles, time-saving and labor-saving, and simple operation is provided. The utility model provides an adjustable pull rod, which is characterized in that it includes a length adjustment component and an angle adjustment component. The length adjustment component and the angle adjustment component are connected through a spiral screw, the right end of the spiral screw is spirally sleeved inside the left end of the length adjustment component, and the left end of the spiral screw is sleeved inside the right end of the angle adjustment component. The right end of the length adjustment component is connected to a right calliper, and the left end of the angle adjustment component is connected to a left calliper. The left calliper and the right calliper are used to connect profiles.

[0005] The length adjustment assembly includes a trapezoidal nut spirally connected to the right end of the spiral screw and a telescopic sleeve welded to the right end of the trapezoidal nut. Rotating the trapezoidal nut can drive the telescopic sleeve to rotate, thereby causing the spiral screw to telescope in and out of the telescopic sleeve. That is, by rotating the telescopic sleeve in the opposite direction to unscrew the spiral screw from the telescopic sleeve, the length of the pull rod can be extended. By rotating the telescopic sleeve in the forward direction to retract the spiral screw into the telescopic sleeve, the length of the pull rod can be shortened, thereby tightening the two ends of the pull rod.

[0006] An adjustable telescopic rod is nested and assembled on the right side of the interior of the telescopic sleeve. The adjustable telescopic rod can be fixed in the telescopic sleeve and can also be pulled out or pushed in from the telescopic sleeve to further adjust the length of the pull rod.

[0007] The angle adjustment assembly includes a rotating base sleeved with the left end of the spiral screw and a hollow sleeve welded to the left end of the rotating base. Rotating the rotating base can drive the hollow sleeve to rotate, thereby adjusting the angle between the pull rod and the profile.

[0008] The rotating base is connected to the screw rod via built-in steel balls, and the rotating base can rotate 360 ​​degrees around the axis of the screw rod.

[0009] The adjustable telescopic rod is evenly distributed with positioning holes that are perpendicular to its axis and pass through the adjustable telescopic rod. Correspondingly, the right end of the telescopic sleeve is provided with a locking hole that is perpendicular to its axis and passes through the telescopic sleeve. After aligning the positioning hole with the locking hole, a bolt can be passed through the positioning hole and the locking hole, and nuts are used to tighten the two ends of the bolt to fix the adjustable telescopic rod in the telescopic sleeve.

[0010] The number of the positioning holes is 6. By adjusting the positions of the positioning holes on the adjustable telescopic rod that are aligned with the locking holes, the length of the pull rod can be adjusted.

[0011] A telescopic rod joint is welded to the right end portion of the adjustable telescopic rod, and the right end of the telescopic rod joint is connected to a rotating lifting ring by a bolt. The right end of the rotating lifting ring is fixedly connected to the right clamp, and the right clamp is used to clamp the profile on the right side. The rotating lifting ring can rotate, thereby driving the right clamp to rotate, and is used to adjust the angle between the right clamp and the profile.

[0012] A sleeve joint is welded to the left end portion of the hollow sleeve, and the left end of the sleeve joint is connected to the left hook by a bolt. The left hook is used to clamp the profile on the left side. When the hollow sleeve rotates, it can drive the sleeve joint to rotate, and then drive the left hook to rotate, which is used to adjust the angle between the left hook and the profile.

[0013] The rotating lifting ring includes a bearing seat fixedly connected to the telescopic rod joint, and a pull ring inserted into the center of the bearing seat through a bearing, and the pull ring can rotate 360 ​​degrees on the bearing seat.

[0014] The left end of the screw rod is also fixed with a fixing component, and the fixing component is tightly fitted on the left end of the screw rod. After the screw rod passes through the fixing component, it extends into the rotating base. When the fixing component is fixed with a tool, the screw rod is fixed and cannot rotate. At this time, the trapezoidal nut can be rotated to make it rotate on the screw rod.

[0015] The fixing component is provided with a pin hole, and the pin hole is used to insert a wrench to fix it.

[0016] The utility model has the following advantages:

[0017] 1. The length of the pull rod is adjustable, and the adjustment of the pull rod length is convenient and quick, which is suitable for working occasions with unstable height. It has a simple and compact structure, energy saving and environmental protection, high work efficiency, low production cost, no damage to profiles, time-saving and labor-saving, and simple operation.

[0018] 2. The hollow sleeve on the left side of the rotating sleeve can rotate, which can drive the left side of the calliper to rotate, making it easier to adjust the angle during fixed operation. Similarly, the right side ring can also rotate to facilitate the installation of the calliper on the profile. BRIEF DESCRIPTION OF THE DRAWINGS
