Description

Technical Field

[0001] This utility model belongs to the field of marine oil engineering technology, and in particular relates to an auxiliary device for flipping I-beams. Background Technology

[0002] A large number of I-beams are needed in the on-site construction of offshore oil projects. I-beams are structural steel, formed by a web and flanges at opposite ends of the web. On the construction site, I-beams are stacked together, but processing I-beams requires processing them individually. Since the distance between the machinery used to process I-beams and the stacked I-beams is relatively short, and it is inconvenient to transport them by mechanical equipment, workers often manually flip and move the I-beams over short distances.

[0003] On construction sites, it is usually necessary to manually flip the I-beams. Manual flipping is difficult and requires the cooperation of multiple people. It is time-consuming and labor-intensive, and crushing accidents can easily occur during flipping, which can easily cause injury to construction workers and pose a significant safety hazard.

[0004] Therefore, there is an urgent need to design an auxiliary device for flipping I-beams to solve the problems mentioned above. Utility Model Content

[0005] To address the technical problems mentioned in the background art, such as the difficulty of manually flipping I-beams, the need for multiple people to cooperate, the time and labor costs, and the risk of crushing accidents that could injure construction workers during the flipping process, an auxiliary device for flipping I-beams is provided to solve these problems.

[0006] To achieve the above objectives, the specific technical solution of the auxiliary device for flipping I-beams of this utility model is as follows:

[0007] An auxiliary device for flipping an I-beam includes a handle and a pressure plate. The pressure plate is hinged to one end of the handle. A first bolt is connected to the handle and abuts against the pressure plate. A connecting plate is hinged to the pressure plate, and a second bolt is provided on the connecting plate. Both the second bolt and the pressure plate abut against one side of the flange of the I-beam. The side of the I-beam flange away from the pressure plate and the second bolt abuts against the connecting plate to flip the I-beam. Rotating the first bolt disengages it from the pressure plate, and the second bolt and the connecting plate engage with the flange of the I-beam. The pressure plate presses onto the steel plate to fix the steel plate onto the I-beam, completing the welding process.

[0008] Furthermore, a base plate is connected to one end of the handle, and first side plates are spaced apart on the base plate, with a pressure plate hinged between the two first side plates.

[0009] Furthermore, a first nut is connected to the base plate, and a first bolt is screwed onto the first nut. One end of the first bolt passes through the first nut and abuts against the pressure plate to limit the position of the pressure plate.

[0010] Furthermore, the pressure plate is provided with a pressing groove, and the first bolt is abutted in the pressing groove.

[0011] Furthermore, the connecting plate is provided with second side plates at intervals, and the end of the pressure plate away from the first side plate is hinged between the two second side plates.

[0012] Furthermore, the connecting plate has a second side plate and a fixing plate spaced apart on one side. The fixing plate is hinged with a second bolt at the end away from the connecting plate.

[0013] Furthermore, the fixing plates are symmetrically welded onto the connecting plates, and the fixing plates are arranged in an L-shape.

[0014] Furthermore, the pressure plate is rotatably positioned between two fixed plates, and the pressure plate is provided with anti-slip grooves that abut against the flange plate of the I-beam.

[0015] Furthermore, a first screw and a second screw are spaced apart on the pressure plate, with the first screw hinged between the first side plates and the second screw hinged between the second side plates.

[0016] Furthermore, the adjacent sides of the first and second side plates are both designed as arcs so that the pressure plate can rotate without the first and second side plates coming into contact.

[0017] The auxiliary device for flipping I-beams of this invention has the following advantages:

[0018] By rotating the handle, a pressure plate connected to the handle presses against the flange of the I-beam. The first bolt limits the pressure plate. The pressure plate, the second bolt, and the connecting plate clamp the flange of the I-beam. As the handle rotates, the I-beam flips. When the second bolt and the connecting plate engage with the flange, the first bolt disengages from the pressure plate, allowing the pressure plate to press against the steel plate on the I-beam, thus welding the steel plate to the I-beam. This invention allows a single person to complete the flipping of the I-beam, saving time and effort. Flipping the I-beam will not crush the worker's hands, ensuring worker safety.

[0026] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0027] Those skilled in the art will understand that although some embodiments herein include certain features included in other embodiments but not others, combinations of features from different embodiments are intended to be within the scope of this invention and form different embodiments. For example, in the claims, any of the claimed embodiments can be used in any combination.

[0028] The following is a reference to the appendix. Figure 1 To be continued Figure 5 This invention describes an auxiliary device for flipping I-beams.

[0029] like Figure 1 As shown, the auxiliary device for flipping the I-beam in this utility model includes a handle 1 and a pressure plate 2. The pressure plate 2 is hinged to one end of the handle 1. A first bolt 3 is connected to the handle 1 and abuts against the pressure plate 2. A connecting plate 5 is hinged to the pressure plate 2 and a second bolt 4 is provided on the connecting plate 5. The second bolt 4 and the pressure plate 2 abut against one side of the flange of the I-beam. The side of the flange of the I-beam away from the pressure plate 2 and the second bolt 4 abuts against the connecting plate 5 to flip the I-beam. When the first bolt 3 is rotated, the first bolt 3 disengages from the pressure plate 2, and the second bolt 4 and the connecting plate 5 are engaged on the flange of the I-beam. The pressure plate 2 presses onto the steel plate to fix the steel plate on the I-beam, thus completing the welding.

[0030] By rotating the handle 1, the pressure plate 2 connected to the handle 1 presses against the flange plate of the I-beam, and the first bolt 3 limits the pressure plate. The pressure plate 2, the second bolt 4, and the connecting plate 5 clamp the flange plate of the I-beam. As the handle 1 rotates, the I-beam is flipped. When the second bolt 4 and the connecting plate 5 are engaged with the flange plate, the first bolt 3 disengages from the pressure plate 2, allowing the pressure plate 2 to press the steel plate on the I-beam, thus welding the steel plate onto the I-beam. This application allows a single person to complete the I-beam flipping operation, saving time and effort. Flipping the I-beam will not crush the worker's hands, ensuring the worker's safety.

[0031] Furthermore, such as Figure 1 and Figure 2 As shown, one end of the handle 1 is connected to a base plate 6, and the base plate 6 is provided with first side plates 7 at intervals. A pressure plate 2 is hinged between the two first side plates 7. A first nut 9 is connected to the base plate 6, and a first bolt 3 is screwed onto the first nut 9. One end of the first bolt 3 passes through the first nut 9 and abuts against the pressure plate 2 to limit the pressure plate 2. The pressure plate 2 is provided with a pressing groove 11, and the first bolt 3 abuts against the pressing groove 11.

[0032] In this embodiment, preferably, one end of the handle 1 is the part held by the construction worker, and the other end of the handle 1 is vertically welded to the base plate 6. The base plate 6 is vertically welded to the side away from the handle 1 with a first side plate 7. The two first side plates 7 are spaced apart, so that the pressure plate 2 is hinged between the two first side plates 7.

[0033] A first nut 9 is welded to one side of the base plate 6, and a first bolt 3 is screwed onto the first nut 9. One end of the first bolt 3, which is screwed into the first nut 9, abuts against the pressure plate 2. By adjusting the screwing position of the first bolt 3, the fixed position of the pressure plate 2 can be changed. Preferably, the pressure plate 2 is provided with a pressure groove 11. When it is necessary to flip the I-beam, the first bolt 3 abuts against the pressure groove 11 to achieve the limiting effect on the pressure plate 2.

[0034] In a preferred embodiment, when it is necessary to weld a steel plate onto the I-beam, the size of the first bolt 3 screwed into the first nut 9 is reduced, that is, the first bolt 3 is moved away from the pressure groove 11 of the pressure plate 2, the connecting plate 5 and the second bolt 4 are engaged on the flange plate of the I-beam, and the handle 1 is rotated so that the pressure plate 2 presses onto the steel plate, thereby fixing the steel plate and completing the construction operation of welding the steel plate onto the I-beam.

[0035] Furthermore, such as Figures 2 to 4 As shown, the connecting plate 5 is provided with second side plates 8 at intervals, and the end of the pressure plate 2 away from the first side plate 7 is hinged between the two second side plates 8; the connecting plate 5 is provided with a fixing plate 12 at intervals on the side where the second side plates 8 are provided, and the end of the fixing plate 12 away from the connecting plate 5 is hinged with a second bolt 4; the fixing plate 12 is symmetrically welded to the connecting plate 5, and the fixing plate 12 is arranged in an L-shape.

[0036] In this embodiment, the connecting plate 5 is welded with second side plates 8 at intervals, and the end of the pressure plate 2 away from the first side plate 7 is hinged between the two second side plates 8, so that the pressure plate 2 is rotatably mounted on the connecting plate 5.

[0037] Fixing plates 12 are welded at intervals on the connecting plate 5. The two fixing plates 12 are located on both sides of the two second side plates 8. Preferably, the fixing plates 12 are L-shaped steel plates. The ends of the fixing plates 12 away from the connecting plate 5 are respectively welded with second nuts 10. The second bolts 4 are screwed onto the fixing plates 12 through the second nuts 10. By adjusting the screwing position of the second bolts 4, various thicknesses of I-beams can be used.

[0038] When flipping the I-beam, the gap between the two second bolts 4 and the connecting plate 5 is engaged with the flange of the I-beam. As the handle 1 is rotated, the pressure plate 2 presses the flange of the I-beam. Continue to rotate the handle 1 to achieve the flipping of the I-beam.

[0039] Furthermore, such as Figure 5 As shown, the pressure plate 2 is rotatably disposed between two fixed plates 12. The pressure plate 2 is provided with an anti-slip groove 13, which abuts against the flange of the I-beam. The pressure plate 2 is provided with a first screw 14 and a second screw 15 at intervals. The first screw 14 is hinged between the first side plates 7, and the second screw 15 is hinged between the second side plates 8. The adjacent sides of the first side plate 7 and the second side plate 8 are both set with arc shape so that the pressure plate 2 can rotate without the first side plate 7 and the second side plate 8 contacting each other.

[0040] In this embodiment, preferably, the pressure plate 2 is located between the two fixed plates 12, that is, the contact position between the pressure plate 2 and the flange of the I-beam is located between the two second bolts 4; the side of the pressure plate 2 that contacts the flange of the I-beam is provided with an anti-slip groove 13, which increases the friction between the pressure plate 2 and the I-beam and helps to flip the I-beam.

[0041] The pressure plate 2 is connected to a first screw 14 and a second screw 15. The pressure plate 2 is hinged to the first side plate 7 by the first screw 14, so that the pressure plate 2 can rotate relative to the handle 1. The pressure plate 2 is hinged between the second side plates 8 by the second screw 15. When the first bolt 3 is fixed to the pressure plate 2, the connecting plate 5 can rotate relative to the pressure plate 2.

[0042] Preferably, the first side plate 7 and the second side plate 8 are both set to an arc shape on adjacent sides, so that when the pressure plate 2 rotates relative to the connecting plate 5, or when the connecting plate 5 rotates relative to the pressure plate 2, the first side plate 7 and the second side plate 8 do not contact each other.

[0043] The working principle of the auxiliary device for flipping the I-beam in this utility model is as follows:

[0044] When flipping the I-beam:

[0045] First, adjust the screw position of the first bolt 3 so that the first bolt 3 abuts against the pressure groove 11 of the pressure plate 2 to fix the pressure plate 2.

[0046] Then, adjust the appropriate gap between the connecting plate 5 and the second bolt 4, and insert the flange plate of the I-beam;

[0047] Finally, rotate handle 1 to make pressure plate 2 abut against the flange of the I-beam, and continue rotating handle 1 to complete the flipping of the I-beam.

[0048] When welding steel plates onto I-beams:

[0049] First, adjust the screw position of the first bolt 3 so that the screw end of the first bolt 3 is far away from the pressure groove 11 of the pressure plate 2;

[0050] Then, adjust the appropriate gap between the connecting plate 5 and the second bolt 4, and insert the flange plate of the I-beam;

[0051] Finally, rotate handle 1 to press the pressure plate 2 onto the steel plate, completing the welding of the steel plate.

[0052] Based on the auxiliary device for flipping I-beams, this utility model, by rotating the handle 1, causes the pressure plate 2 connected to the handle 1 to press against the flange plate of the I-beam, and the first bolt 3 acts as a limit for the pressure plate 2. The pressure plate 2, the second bolt 4, and the connecting plate 5 clamp the flange plate of the I-beam. As the handle 1 rotates, the I-beam is flipped. When the second bolt 4 and the connecting plate 5 are engaged on the flange plate, the first bolt 3 disengages from the pressure plate 2, allowing the pressure plate 2 to press against the steel plate on the I-beam, thus achieving the welding of the steel plate onto the I-beam. This application allows a single person to complete the I-beam flipping work, saving time and effort. Flipping the I-beam will not crush the hands of the construction worker, ensuring the safety of the construction worker.

[0053] Obviously, the above embodiments of this utility model are merely examples for clearly illustrating the present utility model, and are not intended to limit the implementation of the present utility model. Those skilled in the art can make other variations or modifications based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this utility model should be included within the protection scope of the claims of this utility model.
