[0032] See also Figure 1 and Figure 2 The present application specifically provides a scissor-type positioning and correction device for a ship longitudinal bone, including a gantry 1 and a pushing mechanism 2.

[0033] The door frame 1 includes two legs 101 and a cross brace 102 connected between the two legs 101, and the cross brace 102 is arranged transversely at the upper part of the door frame 1.

The pushing mechanism 2 is used to extend the pushing portion 230 downward to squeeze, correct and position the longitudinal bone, and retract it upward after welding. The setting of the pushing mechanism 2 assists the welding of the longitudinal bone and ensures the welding accuracy of the longitudinal bone.

[0034] It should be noted that the legs 101 and the cross braces 102 in the door frame 1 are both made of carbon fiber square tubes to reduce the weight of the device and facilitate movement.

[0035] In an practicable manner, the pushing mechanism 2 is a quadrilateral scissor-type structure, and the pushing mechanism 2 includes a first fixing member 201 disposed at the top, a second fixing member 202 disposed at the bottom, and a third fixing member 203 and a fourth fixing member 204 disposed at both sides. The pushing mechanism 2 also includes four connecting members, and the ends of the four connecting members are hinged in sequence.

[0036] Specifically, Figure 2 As shown, the pushing mechanism 2 includes a first connecting member 211, a second connecting member 212, a third connecting member 213, and a fourth connecting member 214. One end of the first connecting member 211 and the second connecting member 212 are both hinged to the first fixing member 201, the third connecting member 213 and the first connecting member 211 are both hinged to the third fixing member 203, the second connecting member 212 and the fourth connecting member 214 are both hinged to the fourth fixing member 204, and the third connecting member 213 and the fourth connecting member 214 are both hinged to the second fixing member 202.

[0038] The third fixed block is connected to the fourth fixed block by a threaded rod 220, and the threaded rod 220 is arranged horizontally. A rotation bearing is provided at one end of the threaded rod 220, and the threaded rod 220 is rotationally connected to the fourth fixed block through the rotation bearing, and the other end of the threaded rod 220 is threadedly connected to the threaded through hole of the third fixed block. By controlling the rotation of the threaded rod 220, the distance between the third fixed block and the fourth fixed block is increased or decreased, so that the distance between the first fixed block and the second fixed block is reduced or increased, thereby reducing or increasing the extension distance of the push portion 230.

[0039] By setting the quadrilateral scissor-type structure, the pushing part 230 can extrude, correct and position the longitudinal bone, which is convenient for subsequent welding.

[0040] It should be noted that the pushing portion 230 includes a pushing rod and a pushing disc, the diameter of the pushing disc is larger than the diameter of the pushing rod, and the setting of the pushing disc increases the contact area with the longitudinal bone, preventing damage to the surface of the longitudinal bone during the process of pushing the longitudinal bone downward.

[0041] A group of connecting ear plates are arranged at the connection of two adjacent connecting members, the two adjacent connecting members are hinged through the two groups of connecting ear plates, and the fixing block is arranged between the connecting ear plates.

[0042] A group of first fixing lugs is provided on the first fixing block, and the first fixing lugs are respectively hinged to the connecting lugs of the first connecting member 211 and the connecting lugs of the second connecting member 212. A group of second fixing lugs is provided on the second fixing block, and the second fixing lugs are respectively hinged to the connecting lugs of the third connecting member 213 and the connecting lugs of the fourth connecting member 214.

[0043] In one practicable manner, a motor 240 is provided on the fourth fixed block, and the output shaft of the motor 240 is transmission-connected to the threaded rod 220. By controlling the rotation speed and rotation direction of the motor 240, the length of the threaded rod 220 inserted into the third fixed block is controlled, thereby controlling the distance between the third fixed block and the fourth fixed block.

[0044] It should be noted that the motor 240 is a 150W DC motor 240, and the motor 240 and the threaded rod 220 are connected via a reduction gear transmission. The reduction gear is set to transmit the rotation displacement output by the motor 240 to the threaded rod 220, thereby controlling the rotation of the threaded rod 220. The reduction gear and the quadrilateral scissor structure are labor-saving components, and the motor 240 can control the push mechanism 2 to generate a downward pressure of 20,000N, thereby ensuring the fixing effect of the longitudinal bone and improving the subsequent welding quality.

[0045] Compared with the traditional cylinder push rod structure, the quadrilateral scissors-type structure in the present application converts the circular motion of the motor 240 into linear motion, which can increase the pushing range of the pushing part 230. At the same time, through the threaded screw connection, the device also has a self-locking function during the pressing process, and has the characteristics of long pressing stroke and large thrust.

[0046] It should be noted that the maximum thrust generated by the quadrilateral scissor-type structure in this embodiment is 20000N, the rated voltage is 12V, and the pushing stroke is 300mm+120mm.

[0047] In one feasible manner, a pull rod 3 is provided at the top of the door frame 1, and the pull rod 3 is connected between the two legs 101 and is provided at the top of the legs 101. By pulling the pull rod 3, the device is moved along the length direction of the longitudinal bone, so as to move the device to the deformed part of the longitudinal bone and perform push-down correction and positioning.

[0048] In one practicable manner, a sliding mechanism is provided at the bottom of the door frame 1, and the sliding mechanism is used to assist the device in sliding on the steel plate when the pull rod 3 is pulled, so that the device can be quickly and accurately positioned at a predetermined correction position of the longitudinal bone.

[0050] It should be noted that when it is necessary to pull the device for a longer displacement, pull the pull rod 3 to make the two front pulleys or the two rear pulleys in the sliding mechanism contact the steel plate, and make the device slide forward or backward on the steel plate. By setting the sliding mechanism, effort can be saved and pulling time can be saved.

[0051] In an practicable manner, an electromagnet 5 is provided at the bottom of the leg 101, and the electromagnet 5 is used to connect with the steel plate through magnetic force after being energized. Therefore, the electromagnet 5 is energized or deenergized to control the connection or disconnection of the electromagnet 5 with the steel plate.

[0052] It should be noted that the maximum suction force of the electromagnet 5 is 8000N, the rated voltage of the electromagnet 5 is 12V, and the power is 35W.

[0053] In one feasible manner, a side push mechanism 7 is provided at the bottom of the support leg 101, and the side push mechanism 7 pushes the side of the longitudinal bone to adjust the position of the longitudinal bone in the horizontal direction, thereby ensuring the accurate position of the longitudinal bone and the accuracy of subsequent welding.

[0054] In one practicable manner, the side thrust mechanism 7 is a cylinder, and the position of the longitudinal bone is adjusted by controlling the extension length of the cylinder rod of the cylinder.

[0055] In another practicable manner, the side thrust mechanism 7 is an electric push rod, and the position of the longitudinal bone is adjusted by controlling the extension length of the electric push rod.

[0056] It should be noted that the stroke of the electric push rod is 100m, the speed is 5mm / s, the thrust of the electric push rod is 2000N, the rated voltage of the electric push rod is 12V, and the power is 35W.

[0057] In an practicable manner, a battery pack 6 is provided on the leg 101, the specification of the battery pack 6 is 18650 three-series twelve-parallel batteries, the rated voltage of the battery pack 6 is 12V, and the capacity of the battery pack 6 is 36Ah. The battery pack 6 is used as the power source of the device to supply power, making the device more portable.

[0058] In an practicable manner, the connecting plate is connected to the bottom of the leg 101 through a folding plate. In order to prevent the pulley block 4 from affecting the operation of the electromagnet 5 or the side push mechanism 7 at the bottom of the leg 101, each folding plate is folded to the left and right sides of the scissor-type positioning and correction device, so that the two pulley blocks 4 are arranged on the left and right sides of the bottom of the door frame 1 through the folding plates.

[0059] In an practicable manner, an electromagnet switch 81, an electric push rod forward switch 82, and an electric push rod backward switch 83 are respectively arranged on the support leg 101. The electromagnet switch 81 is used to control the power on or off of the electromagnet 5. The electric push rod forward switch 82 and the electric push rod backward switch 83 are both electrically connected to the electric push rod to control the electric push rod to move forward or backward respectively. The above switches are arranged on the support leg 101 for easy operation.

[0060] A push mechanism downward switch 84 and a push mechanism upward switch 85 are provided on the cross brace 102. Both the push mechanism downward switch 84 and the push mechanism upward switch 85 are electrically connected to the motor 240 to control the forward or reverse rotation of the motor.

[0061] When the present application is used, the device is moved to a predetermined position of the longitudinal bone by a sliding mechanism, and the electromagnet 5 is turned on to fix the device and the steel plate. After adjusting the position of the longitudinal bone in the horizontal direction by the side push mechanism 7, the longitudinal bone is pressed down and corrected by the top push mechanism 2, and welding is performed when there is no gap between the longitudinal bone and the steel plate. After welding is completed, the top push mechanism 2 is retracted and the electromagnet 5 is powered off. When other positions of the longitudinal bone need to be corrected, the device is moved to the next position, and the above steps are repeated to correct the positioning of the longitudinal bone.

[0062] The present application assists the welding of the longitudinal bones by setting up the pushing mechanism 2, thereby ensuring the welding quality of the longitudinal bones and the steel plates.

[0063] Compared with the traditional cylinder push rod structure, the present application converts the circular motion of the motor 240 into linear motion through the setting of a quadrilateral scissor-type structure, which can increase the pushing range of the pushing part 230. At the same time, through the threaded screw connection, the device also has a self-locking function during the pressing process, and has the characteristics of long pressing stroke and large thrust.

[0064] The present application can adjust the position of the longitudinal bone in the horizontal direction by setting the side thrust mechanism 7, thereby ensuring the accurate position of the longitudinal bone and the welding quality of the longitudinal bone.

[0065] The present application adopts the setting of the sliding mechanism, which makes the present application more labor-saving during the moving process, saves pulling time and improves work efficiency.

[0066] The present application adopts the arrangement of the electromagnet 5, which is connected to the steel plate through magnetic force after being energized, thereby ensuring the stability of the longitudinal bone during welding and preventing the longitudinal bone from shifting during welding.

[0067] In summary, the present application can position and correct the longitudinal bones during the welding process of the longitudinal bones to assist in the welding alignment of the longitudinal bones. The present application effectively improves the welding efficiency and welding quality of the longitudinal bones, saves a lot of manpower and material resources, is conducive to improving the construction efficiency and construction quality of ships, and is conducive to promotion and use.
