Description

Technical Field

[0001] The invention relates to the technical field of ship welding, and in particular to a positioning welding device and method based on a container ship steel structure. Background Art

[0002] Container ships are ships used to load international standard containers. Their cargo capacity is usually expressed in terms of the number of 20-foot standard containers. Container ships, also known as "container ships", are mainly divided into two types: ‌Full container ships‌: All cabins and decks of this type of ship are dedicated to loading containers, usually used for long-distance transportation; ‌Semi-container ships‌: Part of the cabins of this type of ship are used to load containers, suitable for medium and short-distance transportation; Container ships need to weld partitions in their transport areas and weld guide rails on the partitions according to the size of the containers, thereby separating the container placement area, facilitating the lifting of containers and ensuring the safety and stability of container transportation. Therefore, welding equipment is required to assist in processing.

[0003] A welding positioning device for ship deck welding disclosed in a patent application with reference publication number CN107520564B can assist in positioning the vertical plate during vertical plate welding, replacing the yard plate, avoiding welding deformation, and making the operation simpler.

[0004] At present, the welding of guide rails on container ships mostly adopts the method of setting up brackets and cooperating with clamps to complete the positioning and fixing of the guide rails, so as to perform the welding work. For example, the above-mentioned welding positioning device also adopts the method of setting up a fixing frame to complete the welding process. However, the method of setting up brackets for the guide rails causes a large workload for welding positioning, which is time-consuming and labor-intensive. The installation and disassembly both require a long period of time, which affects the welding efficiency of the ship guide rails. It is impossible to freely assemble on the ship to complete the continuous moving positioning welding process, which is not conducive to the welding construction of the ship guide rails.

Each positioning frame 3 is provided with a driving member for controlling the movement; like Figure 5 , Figure 6 and Figure 7 As shown, two processing units are arranged on two welding frames to complete welding processing. Each processing unit includes a moving part and two welding parts. When the moving part moves forward, the two welding parts are controlled by friction to move to a predetermined welding position to complete follow-up welding. When the moving part is reset, the welding frame is controlled by the driving part to complete coordinated walking welding. like Figure 8 As shown, in the embodiment of the present invention, each positioning frame 3 includes: A concave frame 301 is arranged on the partition 1, and wheel seats 302 are arranged on both sides of the bottom of the concave frame 301.

The positioning of the welding frame is completed by the cooperation of the laser receiver 5 and the laser transmitter 6; It is worth noting that when the welding frame is controlled: the two positioning frames 3 are transferred to the partition 1 by providing the welding frame, and the guide rail 2 is confined between the two positioning frames 3, and the guide rail 2 is confined therein by the concave frame 301, and then the top pressure wheel 306 contacts the top of the guide rail 2, and at the same time, the adjustment screw 308 is controlled to adjust the two side pressure wheels 307 to contact the side of the guide rail 2, so as to complete the multi-directional clamping positioning of the guide rail 2, and then the wheel seat 302 of the concave frame 301 is controlled to be close to the partition 1, so that the permanent magnet wheel 303 is in contact with the partition The plate 1 contacts and completes the adsorption fixation, and a welding area is formed by two positioning frames 3 together, which can accurately position the guide rail 2 at the welding area position, which is beneficial to the subsequent welding construction. In order to ensure the stability of each transfer welding, a laser transmitter 6 is arranged on the moving seat, and a laser receiver 5 is arranged on the concave frame 301, so as to ensure the relative position stability of the welding frame. When the position of the welding frame fluctuates, the electric push rod 305 is started to fine-tune the position of the concave frame 301, further improving the overall welding accuracy; like Figure 4 As shown, in the embodiment of the present invention, the mobile seat includes: The card base 40 is correspondingly slidably engaged with the top of the partition 1, and two supporting wheels in contact with the partition 1 are symmetrically rotated in the card base 40, and a power wheel 41 is installed in the middle position of the card base 40, and a walking motor connected to the power wheel 41 is installed on one side of the card base 40.

[0024] Among them, electrical components such as the walking motor, driving motor, and electric push rod 305 are all connected to switches through wires, and the switches are electrically connected to the controller.

[0027] Embodiment 3: Based on the moving part provided in Embodiment 1, this embodiment provides a further technical solution for the moving part.

[0028] like Fig.12 and Fig.13 As shown, each moving part includes: The adjusting seat 16 is arranged between the two concave frames 301, and friction plates 17 are arranged on both sides of the adjusting seat 16. A screw rod 18 is rotatably arranged in the adjusting seat 16, and the two ends of the screw rod 18 are arranged to rotate and extend out of the adjusting seat 16, and a screw rod nut 19 is slidably engaged in the adjusting seat 16, and the screw rod nut 19 is arranged on the outside of the screw rod 18 corresponding to the transmission sleeve; Two No. 5 bevel gears 20 are fixedly sleeved on the ends of the screw rod 18 and meshed with the plurality of No. 4 bevel gears 15 respectively, and a driving motor connected to the screw rod 18 is installed on one of the concave frames 301; The control area is provided at the bottom of the screw nut 19, a slider 21 is slidably engaged in the control area, a spring No. 1 is provided between the slider 21 and the control area, and a stopper for positioning the slider 21 at the extreme position is provided in the control area; Two inclined platforms 22 are symmetrically arranged at the bottom of both sides of the screw nut 19; Each mobile also includes: The welding arm 23 is arranged at the bottom of the slider 21; Two friction wheels 24 are symmetrically rotatably arranged on both sides of the welding arm 23 through a bracket, each friction wheel 24 is in friction contact with the friction plate 17, and each friction wheel 24 is provided with a ratchet pawl mechanism. Specifically, the ratchet is arranged on the shaft end of the friction wheel 24, and the pawl is rotatably arranged on the bracket of the friction wheel 24 through a torsion spring, and the friction wheel 24 is controlled to rotate in one direction through the cooperation of the pawl and the ratchet; It is worth mentioning that when welding the guide rail 2: by providing a processing unit, after positioning the guide rail 2, the drive motor is controlled to rotate forward, driving the screw 18 to rotate, so that the screw nut 19 is moved forward under the restriction of the adjustment seat 16. At this time, the one-way bearing 14 of the driving member is disconnected and no power is transmitted. At this time, the ratchet pawl mechanism on the friction wheel 24 is in a locked state. Therefore, when the screw nut 19 moves forward, the friction wheel 24 and the friction plate 17 are in friction contact to generate resistance, so that the welding arm 23 and the slider 21 produce a lagging movement, so that the welding arm 23 and the slider 21 squeeze the No. 1 spring to move in the control area. Since the inclined platforms 22 are provided on both sides of the screw nut 19, the welding arm 23 controls the guide wheel 26 thereon to contact with the inclined platform 22 when moving. Under the squeezing of the side track line of the inclined platform 22, the guide wheel 26 can be squeezed and moved, so that the No. 1 rack 25 Following the movement, the power conversion is performed through the connecting gear 28, so that the second rack 27 drives the fixed arm 29 to move toward the side of the guide rail 2, so that the welding unit 30 moves to the predetermined welding position for welding construction. At the same time, a contact wheel 32 is provided. The contact between the contact wheel 32 and the guide rail 2 can further position the guide rail 2, and at the same time, the position of the welding unit 30 can be limited, thereby ensuring the consistency of welding and improving the welding quality. When the welding unit 30 moves to the extreme welding position, the driving motor is controlled to reverse and drive the screw 18 to rotate. At this time, the friction wheel 24 is unlocked, and the one-way bearing 14 is locked for power connection. Since the friction resistance between the friction wheel 24 and the friction plate 17 is released, the welding arm 23 and the slider 21 are reset, and at the same time, the fixed arm 29 and the welding unit 30 are reset away from the welding area to complete the avoidance, thereby improving safety and avoiding the problem of accidental collision. like Fig.14 and Fig.15 As shown, in the embodiment of the present invention, each welding part includes: A rack 25 is slidably disposed on the welding arm 23 of the moving part, and a guide wheel 26 is installed at the front end of the rack 25, and the guide wheel 26 contacts the inclined platform 22 of the moving part to complete the control; The second rack 27 is slidably arranged on the welding arm 23 of the moving part through a bracket.
