[0034] The following describes embodiments of the present invention in detail. Examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended only to explain the present invention and are not to be construed as limiting the present invention.

[0035] like Figures 1 to 5 As shown, this embodiment provides a T-shaped steel correction device for correcting a T-shaped steel 900 welded to a hull plate 800. The T-shaped steel 900 includes a transverse plate 910 and a vertical plate 920 vertically fixed to the lower plate surface of the transverse plate 910. The end of the vertical plate 920 away from the transverse plate 910 is welded to the upper plate surface of the hull plate 800. The T-shaped steel correction device includes two C-shaped plates 100, two sliding rings 200, a plurality of correction bolts 400 and a plurality of pressure bolts 500. The C-shaped plate 100 has an upper plate and a lower plate parallel to each other, and the upper plate and the lower plate are connected by a web. The upper plate, the lower plate and the web form a Side grooves, the two side grooves on the two C-shaped plates 100 are arranged opposite to each other; the two ends of the C-shaped plate 100 are movably installed on the two slip rings 200 respectively, and the two C-shaped plates 100 can move toward or away from each other along the length direction of the slip ring 200, and the C-shaped plate 100 is selectively locked and connected to the slip ring 200; the correction bolt 400 is threaded through the upper plate, and the cross plate 910 can be clamped between the correction bolt 400 and the lower plate; the pressure bolt 500 is threaded through the C-shaped plate 100, and the axis of the pressure bolt 500 is perpendicular to the upper plate, and the end of the pressure bolt 500 is used to press the hull plate 800.

[0036] The T-shaped steel correction device, with the help of the side grooves on the C-shaped plate 100, is able to provide space for the two side parts of the horizontal plate 910, thereby achieving the purpose of limiting the horizontal plate 910 in the width direction, so that the subsequent correction bolts 400 can achieve a stable locking of the horizontal plate 910. The setting of the slip ring 200 enables the relative position of the two C-shaped plates 100 to be determined after adjustment, thereby enabling the T-shaped steel correction device to adaptively adjust the width of the horizontal plate 910, expanding the application scenarios of the T-shaped steel correction device. The use of the correction bolts 400 can achieve the relative position determination of the C-shaped plates 100 and the C-shaped plates 100, ensuring the stable connection of the T-shaped steel correction device on the T-shaped steel 900, ensuring the stable progress of the correction operation, improving the success rate of the correction operation, and ensuring the efficiency of the correction operation. The design of the pressing bolt 500 pressing against the hull plate 800 can cooperate with the content of the cross plate 910 clamped between the correction bolt 400 and the lower plate, so that the T-steel correction device can apply force to the hull plate 800 and the T-steel 900 through the pressing bolt 500, the C-shaped plate 100 and the correction bolt 400. By adjusting the pressing bolt 500 to a predetermined position, the cross plate 910 can produce corresponding deformation under the action of external force, so as to push the cross plate 910 and the vertical plate 920 to produce corresponding position offsets, thereby achieving the correction operation of the T-steel 900. The above structure is easy to use and occupies little space, which simplifies the correction process of the T-steel 900, reduces the labor intensity of the correction operation, and reduces the construction cost of the correction operation. At the same time, the T-steel correction device has a simple and reliable structure, low production cost and is easy to manufacture, and has the advantage of low maintenance difficulty.

[0037] Specifically, the C-shaped plate 100 is made of steel.

[0038] In this embodiment, the upper plate is provided with several mounting holes, each of which is threaded with an adapter nut. The outer wall of the adapter nut is welded to the upper plate, and the adapter nut is threadedly engaged with the correction bolt 400. This design simplifies the difficulty of threading the upper plate and the correction bolt 400, significantly reduces the risk of the correction bolt 400 accidentally slipping relative to the upper plate, effectively reduces the probability of the correction bolt 400 loosening, and ensures the stability of the connection between the C-shaped plate 100 and the T-shaped steel 900.

[0039] In this embodiment, a locking screw is mounted on the upper plate, the axis of which is perpendicular to the upper plate, and the locking screw is inserted through the slip ring 200. The T-shaped steel correction device also includes a locking nut 310, which is threaded onto the locking screw, and the slip ring 200 can be clamped between the locking nut 310 and the upper plate. By providing the locking screw and the locking nut 310, a smooth locking connection between the slip ring 200 and the C-shaped plate 100 is ensured. The locking screw and the locking nut 310 are threadedly connected, resulting in a stable connection and easy assembly and disassembly, reducing the difficulty of locking and unlocking the slip ring 200 and the C-shaped plate 100 and improving the efficiency of the correction operation.

[0040] Specifically, a washer 320 is sleeved on the locking screw, and the slip ring 200 is sandwiched between the locking nut 310 and the slip ring 200. The provision of the washer 320 reduces the rigid collision between the locking nut 310 and the slip ring 200, reduces the risk of damage to the locking nut 310 and the slip ring 200, and ensures the locking effect of the C-shaped plate 100 on the slip ring 200.

[0041] Furthermore, the slip ring 200 has an elongated hole extending therethrough, allowing the locking screw to move relative to the slip ring 200 along the length of the elongated hole, which is perpendicular to the length of the C-shaped plate 100. The provision of the elongated hole helps to define the movement trajectory of the locking screw, preventing the relative position of the C-shaped plate 100 and the slip ring 200 from deviating from the design expectations. This limitation not only ensures the accuracy of the relative position adjustment between the two C-shaped plates 100, but also improves the efficiency of the position adjustment, helping to simplify the correction process.

[0042] In one implementation of this embodiment, the T-shaped steel correction device also includes a locking bolt 330, the axis of the locking bolt 330 is perpendicular to the upper plate, the screw head of the locking bolt 330 is pressed against the lower plate surface of the upper plate, and the screw rod of the locking bolt 330 passes through the upper plate, and the locking screw is the screw rod of the locking bolt 330.

[0043] The design of the locking screw as the screw of the locking bolt 330 allows the locking screw and the C-shaped plate 100 to be set separately. The above limitations reduce the difficulty of setting the locking screw and improve the flexibility of the locking screw arrangement, so that the T-shaped steel correction device can be used in a variety of different work scenarios, expanding the scope of application.

[0044] In another embodiment of this invention, a locking screw is fixed to the upper surface of the upper plate, with the length of the locking screw being perpendicular to the upper plate. This design of fixing the locking screw to the upper surface of the upper plate prevents the locking screw from shifting, ensuring the accuracy of the position adjustment between the C-shaped plate 100 and the slip ring 200, ensuring the proper position adjustment of the C-shaped plate 100, and ensuring that the correction bolt 400 can be pressed at the predetermined position, allowing the T-shaped steel 900 to deform as expected.

[0045] In this embodiment, the C-shaped plate 100 has a relative slotted surface and a welding surface, the side slots are provided on the slotted surface, and a plurality of fixing nuts 110 are welded to the welding surface. The axis of the fixing nut 110 is perpendicular to the upper plate, and each pressure bolt 500 is screwed to at least one fixing nut 110. The above design optimizes the layout of the C-shaped plate 100, avoids position conflicts between the components, simplifies the structure of the C-shaped plate 100, and reduces the space occupied by the T-shaped steel correction device. The provision of the fixing nut 110 enables the smooth screw connection between the pressure bolt 500 and the C-shaped plate 100, limits the moving trajectory of the pressure bolt 500, avoids the pressure bolt 500 from being accidentally displaced, and ensures that the pressure bolt 500 presses the hull plate 800 in place.

[0046] Furthermore, the T-shaped steel correction device also includes a pressing nut 600, the number of which is the same as the pressing bolt 500, and each pressing nut 600 is screwed onto a pressing bolt 500, the pressing nut 600 can be pressed onto the fixing nut 110, and the thread direction of the pressing nut 600 is opposite to that of the fixing nut 110.

[0047] By setting a pressing nut 600 with a thread direction opposite to that of the fixing nut 110, it is possible to prevent the pressing bolt 500 from accidentally moving or even loosening, ensuring that the pressing bolt 500 is always pressed in place throughout the entire correction operation, thereby achieving the expected effect of applying force to the hull plate 800 and improving the success rate of the correction operation.

[0048] For example, each C-shaped plate 100 is screwed with two pressure bolts 500, and there are four fixing nuts 110. The four fixing nuts 110 are respectively arranged at the four corners of the web, and each pressure bolt 500 is screwed with two fixing nuts 110. The above design limits the number of pressure bolts 500 and fixing nuts 110, and also plans the setting positions of the pressure bolts 500 and fixing nuts 110, thereby optimizing the force on the C-shaped plate 100, reducing the risk of irreversible deformation of the C-shaped plate 100, and extending the service life of the C-shaped plate 100. At the same time, the above setting also helps to limit the position where the pressure bolts 500 apply force on the hull plate 800, standardizes the adjustment position of the pressure bolts 500, helps to reduce the frequency of position adjustment of the pressure bolts 500, and thus improves the efficiency of the correction operation.

[0049] In this embodiment, the axis of the correction bolt 400 is perpendicular to the upper plate, and the cross plate 910 can be clamped between the end of the correction bolt 400 and the upper plate surface of the lower plate. Specifically, two correction bolts 400 are screwed onto each upper plate, and the two correction bolts 400 are respectively located at both ends of the upper plate. The above design limits the direction in which the correction bolt 400 applies force to the T-shaped steel 900, and also helps to determine the position in which the correction bolt 400 applies force to the cross plate 910. The above design facilitates standardization of the adjustment position of the correction bolt 400, reduces the frequency of position adjustment of the correction bolt 400, and thus further improves the efficiency of the correction operation.

[0050] Specifically, all the above-mentioned nuts are hexagonal nuts, and all the above-mentioned bolts are hexagonal bolts.

[0051] When the T-shaped steel straightening device is used in a scenario where two T-shaped steels 900 are butted together, the device can ensure that the two T-shaped steels 900 are in the same matching standard. When the two butted T-shaped steels 900 are welded, the device can also serve as a fixing tool for the T-shaped steels 900.

[0052] This embodiment also provides a T-shaped steel correction process, which is applied to the above-mentioned T-shaped steel correction device and includes the following steps:

[0053] Step 1: Place two C-shaped plates 100 on both sides of the horizontal plate 910 so that both sides of the horizontal plate 910 extend into the two side grooves respectively.

[0054] Step 2: Lock and connect the C-shaped plate 100 to the slip ring 200.

[0055] Step 3: Tighten all the correction bolts 400 so that the horizontal plate 910 is sandwiched between the correction bolts 400 and the lower plate.

[0056] Step 4: Tighten all the pressing bolts 500 until each pressing bolt 500 presses against the hull plate 800 .

[0057] Step 5: After the correction is completed, loosen all the pressure bolts 500 and all the correction bolts 400 in sequence, then unlock the C-shaped plate 100 and the slip ring 200, and remove the T-shaped steel correction device from the T-shaped steel 900.

[0058] This T-shaped steel straightening process is simple to operate, simplifies the process of straightening T-shaped steel 900, reduces the difficulty of straightening T-shaped steel 900, and reduces the space required for the straightening operation. Furthermore, the process reduces the workload of the operator, reduces the risk of operator error, and improves the efficiency and success rate of the straightening operation.

[0059] Obviously, the above embodiments of the present invention are merely examples for the purpose of clearly illustrating the present invention, and are not intended to limit the embodiments of the present invention. Those skilled in the art will appreciate that other variations or modifications can be made based on the above description. It is not necessary and impossible to enumerate all embodiments here. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention shall be included within the scope of protection of the claims of the present invention.
