Description

Technical Field

[0001] This utility model belongs to the field of ship curved sheet construction, specifically relating to an adjustable pull code. Background Technology

[0002] The construction of ship sections involves welding together numerous plates and components. During welding, the plates can deform significantly, causing horizontal deviations and reducing the overall precision of the section. Deformation at the joints, in particular, prevents accurate alignment with adjacent sections. Correcting this deformation later increases the difficulty for on-site workers, wastes time, and impacts the efficiency of subsequent ship construction. Current methods to prevent plate deformation involve burning tie rods and supports along the lower edge of the plate on the section. After section construction, these tie rods and supports need to be cut off, leaving weld residue on the plate. On-site workers must then grind away the excess weld residue, increasing workload and reducing efficiency. Utility Model Content

[0003] To solve the above-mentioned technical problems, this utility model provides an adjustable pull bracket to solve the problem of severe deformation of the plate frame when welding ship section components on the plate frame.

[0004] The objective of this invention is achieved through the following technical solution: an adjustable pull code, comprising:

[0005] The top support assembly is detachably fixed at one end to the edge of the part to be welded on the jig plate, and the other end is detachably connected to the upper end of the adjustment assembly.

[0006] The adjustment component is a long, straight, telescopic structure that can extend and retract when subjected to force.

[0007] The bottom fixing component is detachably connected to the bottom of the top adjustment component, and the other end is detachably fixed to the ground.

[0008] Preferably, the top support assembly includes at least one of a magnet and a clamping mechanism.

[0009] Preferably, the connection points between the top support component, the adjustment component, and the bottom fixing component are connected by fixing screws.

[0010] Preferably, the adjustment assembly includes a telescopic rod and a telescopic sleeve, wherein the telescopic rod is screwed into the telescopic sleeve by a thread, and the adjustment assembly is connected to the top support assembly and the bottom fixing assembly through the telescopic rod.

[0011] Preferably, the outer surface of the telescopic sleeve is provided with a circular through hole, and the telescopic sleeve is rotated by inserting a rocker arm into the circular through hole.

[0012] Preferably, the telescopic sleeve is divided into an upper telescopic sleeve and a lower telescopic sleeve, with the circular through hole as the boundary.

[0013] Preferably, the bottom fixing component is a fixing ear plate.

[0014] Compared with the prior art, the present invention has the following advantages:

[0015] This utility model provides an adjustable pull bracket that can prevent severe deformation of the plate frame edges when welding ship section components onto the plate frame. It can be reused repeatedly, can be disassembled immediately after use, requires no other tooling, and does not need to be welded to the plate frame. It also eliminates the need for workers to grind weld residue, thus saving manpower and resources and shortening the construction period.

[0016] The adjustable pull bracket provided by this utility model eliminates the need for additional pull rods and supports on the jig plate to prevent deformation, and eliminates the need to grind weld residue left by welding. It is simple to operate and easy to use, reducing the workload of on-site workers, lowering the construction difficulty for workers, and improving construction efficiency.
