Description

Technical Field

[0001] The present 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] A container ship is a vessel designed to carry international standard containers. Its cargo capacity is usually expressed in terms of the number of 20-foot equivalent units (TEUs). Container ships, also known as "container ships," are mainly divided into two types: Full container ships: These ships have all their cabins and decks dedicated to carrying containers and are typically used for long-distance transport; Semi-container ships: These ships have only a portion of their cabins dedicated to carrying containers and are suitable for short- to medium-distance transport.

[0003] Container ships need to weld partitions in their carrying 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.

[0004] Reference is made to a welding positioning device for ship deck welding disclosed in patent application publication number CN107520564B. The welding positioning device can assist in positioning the vertical plates during welding, replacing the stacking plates, thereby avoiding welding deformation and making the operation simpler.

[0005] At present, for the welding of guide rails on container ships, a bracket is mostly set up and a clamp is used to complete the positioning and fixation of the guide rails, so as to perform the welding work. For example, the above-mentioned welding positioning device also uses a fixed frame to complete the welding process. However, the use of the bracket for the guide rail results in 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.

[0074] Embodiment 1: The present invention provides a technical solution: Figure 1 、 Figure 2 and Figure 3 As shown, a positioning welding device based on a container ship steel structure includes a partition 1, which is specifically made of metal and can be adsorbed by a permanent magnetic wheel 303. A plurality of guide rails 2 are spaced apart on both sides of the partition 1, and further includes:

[0075] The moving seat is arranged on the top of the partition 1 to complete the movement and walking. Two electric hoists for controlling the lifting are symmetrically arranged on both sides of the moving seat;

[0076] Two welding frames are symmetrically arranged on both sides of the partition 1 for positioning the guide rail 2. The two welding frames are respectively connected to two electric hoists to complete the lifting control. The two welding frames are composed of two positioning frames 3 and two guide rods 4. The two guide rods 4 are symmetrically arranged between the two positioning frames 3 to complete the fixation. The positioning and fixation of the guide rail 2 are completed by the two positioning frames 3. Each positioning frame 3 is provided with a driving member to control the movement;

[0077] like Figure 5 、 Figure 6 and Figure 7 As shown, two processing units are set on two welding frames to complete the welding process. Each processing unit includes a moving part and two welding parts. When the moving part moves forward, the friction force controls the two welding parts to move to the predetermined welding position to complete the follow-up welding. When the moving part is reset, the driving part controls the welding frame to complete the coordinated walking welding.

[0078] like Figure 8 As shown, in the embodiment of the present invention, each positioning frame 3 includes:

[0079] The concave frame 301 is arranged on the partition 1, and wheel seats 302 are provided on both sides of the bottom of the concave frame 301. A permanent magnet wheel 303 is rotatably provided in the wheel seat 302. A number one bevel gear 304 is sleeved on one end of the permanent magnet wheel 303. A sliding area is provided on the top of the wheel seat 302, and the bottom of the concave frame 301 is correspondingly slidably engaged with the sliding area. An electric push rod 305 is provided on the sliding area of ​​one of the wheel seats 302. The output end of the electric push rod 305 is transmission-connected to the concave frame 301.

The two connecting ears are respectively connected to the pull rope of the electric hoist, and a fine-tuning area for the connecting ear to move left and right is provided on the concave frame 301;

[0080] The pressing wheel 306 is rotatably disposed at the top of the concave frame 301;

[0081] Two side pressure wheels 307 are symmetrically rotated on both sides of the concave frame 301 through a bracket, and adjusting screws 308 are screwed through both sides of the concave frame 301. The front ends of the two adjusting screws 308 are rotatably connected to the two side pressure wheels 307 respectively. A limit rod is installed on the back side of each side pressure wheel 307, and the limit rod slides through the concave frame 301 accordingly. A hand wheel No. 1 is installed at the tail end of each adjusting screw 308. A laser receiver 5 is provided on the side of the concave frame 301 facing the movable seat, and a laser transmitter 6 is provided on the side of the movable seat facing 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;

[0082] It is worth noting that: when the welding frame is controlled: the two positioning frames 3 are transferred to the partition 1 by providing a 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 adjusting screw 308 is controlled to adjust the two side pressure wheels 307 to contact the side of the guide rail 2, thereby completing 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 plates 1 are in contact and fixed by adsorption. A welding area is formed by two positioning frames 3. The guide rail 2 at the welding area can be accurately positioned, which is beneficial for subsequent welding construction. In order to ensure the stability of each transfer welding, a laser transmitter 6 is provided on the moving seat, and a laser receiver 5 is provided on the concave frame 301, thereby ensuring 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.

[0083] like Figure 4 As shown, in an embodiment of the present invention, the mobile seat includes:

[0084] The card base 40 is correspondingly slidably engaged with the top of the partition 1. 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. A travel motor connected to the power wheel 41 is installed on one side of the card base 40. A handle is installed on the top of the card base 40, and a lifting ear is reserved at the top of the card base 40 to facilitate transfer;

[0085] Four clamping wheels 42 are slidably engaged with the four corners of the clamping seat 40 and are in rotational contact with the side wall of the partition 1;

[0086] Four movable screws 43 are threadedly engaged with each other and are provided at the four corners of the clamping base 40. The four movable screws 43 are rotatably connected to the side walls of the four clamping wheels 42 respectively.

[0087] It should be noted that: when controlling the moving seat: by providing a moving seat, first place the clamping seat 40 on the top of the partition 1, the supporting wheel contacts the top of the partition 1, and then control the moving screw 43 to make the four clamping wheels 42 contact the side wall of the partition 1 to complete the clamping posture, so that the moving seat can be stably restricted on partitions 1 of different sizes. Subsequently, it is only necessary to control the walking motor to rotate the power wheel 41 to control the movement of the moving seat, and the guide rails 2 at different positions can be continuously welded, and the lifting and resetting of the two welding frames can be controlled by the cooperation of the electric hoist.

[0088] Among them, electrical components such as the walking motor, drive motor, and electric push rod 305 are all connected to switches through wires, and the switches are electrically connected to the controller. The specific structure of the controller is not limited. Absolute encoders are installed on the walking motor and drive motor for accurate positioning of the walking motor and drive motor.

[0089] Embodiment 2: Based on the driving member provided in embodiment 1, this embodiment provides a further technical solution for the driving member.

[0090] like Figure 9 and Figure 10 As shown, each drive member includes:

[0091] The first transmission shaft 7 is rotatably mounted on the wheel seat 302 via a bracket. The first transmission shaft 7 is provided with a second bevel gear 8 at both ends thereof, and the second bevel gear 8 at the bottom of the first transmission shaft 7 is meshed with the first bevel gear 304.

[0092] The short shaft 9 is rotatably mounted on the wheel seat 302 via a bracket. A third bevel gear 10 is provided at the tail of each short shaft 9. The third bevel gear 10 is engaged with the first bevel gear 304 at the top of the first transmission shaft 7. An avoidance area 11 is provided inside each short shaft 9.

[0093] The connecting shaft 12 is rotatably mounted on the top of the concave frame 301 through a bracket, and the front end of the connecting shaft 12 is correspondingly inserted into the avoidance area 11 to complete the power connection;

[0094] The power shaft 13 is rotatably mounted on the top of the concave frame 301. A one-way bearing 14 is provided between the power shaft 13 and the connecting shaft 12. A fourth bevel gear 15 is provided at the tail of the power shaft 13.

[0095] It is worth noting that: when the movement of the welding frame is controlled: by providing a driving part, in the reset path of the screw nut 19, the rotational force of the screw 18 is transmitted to multiple No. 4 bevel gears 15 through the No. 5 bevel gear 20, and the power is transmitted to the power shaft 13 through the one-way bearing 14, and the power is transmitted to the No. 1 bevel gear 304 through the No. 3 bevel gear 10 and the No. 2 bevel gear 8, and the permanent magnet wheel 303 is controlled to rotate, so that the welding frame obtains the movement amount, and can complete the active transfer in the reset path of the welding unit 30, thereby completing continuous welding processing, reducing the construction difficulty, and improving the welding efficiency of ship steel structures.

[0096] Embodiment 3: Based on the moving part provided in embodiment 1, this embodiment provides a further technical solution for the moving part.

[0097] like Figure 12 and Figure 13 As shown, each moving part includes:

[0098] The adjustment seat 16 is arranged between the two concave frames 301. Friction plates 17 are provided on both sides of the adjustment seat 16. A screw rod 18 is rotatably provided in the adjustment seat 16, and the two ends of the screw rod 18 are correspondingly extended out of the adjustment seat 16. A screw nut 19 is slidably engaged in the adjustment seat 16, and the screw nut 19 is provided on the outside of the screw rod 18 corresponding to the transmission sleeve;

[0099] Two number five bevel gears 20 are fixedly sleeved on the ends of the screw rod 18 and meshed with the number four bevel gears 15 respectively. A driving motor connected to the screw rod 18 is installed on one of the concave frames 301.

[0100] The control area is provided at the bottom of the screw nut 19, and 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 is provided in the control area to locate the extreme position of the slider 21;

[0101] Two inclined platforms 22 are symmetrically arranged at the bottom of both sides of the screw nut 19;

[0102] Each moving piece also includes:

[0103] The welding arm 23 is provided at the bottom of the slider 21;

[0104] 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. Each friction wheel 24 is provided with a ratchet and pawl mechanism. Specifically, the ratchet is provided on the shaft end of the friction wheel 24, and the pawl is rotatably arranged on the bracket of the friction wheel 24 via a torsion spring. The pawl and the ratchet cooperate to control the unidirectional rotation of the friction wheel 24.

[0105] 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 completed to move 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 there are inclined platforms 22 on both sides of the screw nut 19, the welding arm 23 controls the guide wheel 26 thereon to contact the inclined platform 22 when it moves. Under the squeezing of the side trajectory of the inclined platform 22, the guide wheel 26 can be squeezed and moved, so that the No. 1 rack 25 Following the movement, 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 drive 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. At the same time, the fixed arm 29 and the welding unit 30 are reset to move away from the welding area to complete the avoidance, thereby improving safety and avoiding the problem of accidental collision.

[0106] like Figure 14 and Figure 15 As shown, in the embodiment of the present invention, each welding part includes:

[0107] The first rack 25 is slidably mounted on the welding arm 23 of the moving part. A guide wheel 26 is mounted at the front end of the first rack 25. The guide wheel 26 contacts the inclined platform 22 of the moving part to complete the control.

[0108] The second rack 27 is slidably mounted on the welding arm 23 of the movable member via a bracket. Specifically, a guide bracket is provided on the welding arm 23, and a guide area is provided on the side wall of the second rack 27. The guide bracket is correspondingly slidably engaged into the guide area.

[0109] The connecting gear 28 is rotatably mounted on the welding arm 23 of the moving part via a bracket, and the connecting gear 28 is meshed with the first rack 25 and the second rack 27 respectively;

[0110] The fixed arm 29 is provided at the bottom of the second rack 27. A welding unit 30 is provided at the bottom of the fixed arm 29. The welding unit 30 is specifically a welding head.

[0111] Each weldment includes:

[0112] The control screw 31 is screwed onto the fixed arm 29;

[0113] The contact wheel 32 is rotatably mounted on one side of the fixed arm 29 via a bracket, and the back of the contact wheel 32 is rotatably connected to the control screw 31. A fixing rod connected to the back of the contact wheel 32 is slidably penetrated on the fixed arm 29.

[0114] The second spring 33 is provided between the welding arm 23 of the moving part and the fixed arm 29 to complete the reset control;

[0115] like Figure 11 As shown, in the embodiment of the present invention, it also includes:

[0116] Two No. 1 control chambers 34 are provided on either side of the welding arm 23 of the movable part. A fixed medium is injected into the No. 1 control chamber 34. The medium is specifically one of a liquid and a gas. Each No. 1 control chamber 34 is provided with a No. 1 extrusion piece 35 connected to the fixed arm 29 of the welding part in a sliding and sealing manner.

[0117] Two No. 2 control chambers 36 are provided on one side of the bottom of the two wheel seats 302 of the positioning frame 3. The position of the No. 2 control chamber 36 can be freely assembled on any positioning frame 3, which is convenient for free change according to construction requirements. A No. 2 extrusion piece 37 is slidably and sealedly installed in each No. 2 control chamber 36, and the No. 2 control chamber 36 is connected to the No. 1 control chamber 34 through a pipe;

[0118] Two guide seats are symmetrically arranged on the positioning frame 3. A lifting rod 38 is slidably inserted into each guide seat.

Under normal circumstances, the electromagnet 39 is separated from the partition 1 and connected to the No. 2 extrusion piece 37.

[0119] It is worth noting that: when the welding frame is reinforced: when the welding unit 30 moves forward for welding, due to the relative movement between the fixed arm 29 and the welding arm 23, the fixed arm 29 will push the No. 1 extrusion piece 35 when it moves, and push the medium in the No. 1 control chamber 34 into the No. 2 control chamber 36, so that the No. 2 extrusion piece 37 extends, and the control electromagnet 39 moves down to contact the surface of the partition 1. After that, the electromagnet 39 is energized to complete the fixed position, avoiding the problem of instability of the welding frame during welding, optimizing the construction environment, and being able to complete the welding construction stably. Subsequently, the fixed arm 29 is reset, and the electromagnet 39 is reset under the guidance of the lifting rod 38 through the No. 3 spring control, thereby completing the avoidance and avoiding the problem of damage caused by friction contact between the electromagnet 39 and the partition 1.

By providing two welding frames, the positioning operation of the guide rail 2 can be completed by means of the adsorption and fixation of the two welding frames and the partition 1, without the need to set up a fixed bracket. By providing a processing unit, the movable part can be used to control the movement of the two welding parts to complete the welding action. At the same time, when the movable part is moving for welding, it can control the two welding parts to automatically reset to the welding position, thereby ensuring the stability of the welding. With this design, when the movable part is subsequently reset, the two welding parts can be coordinated to complete the welding operation. The welding parts complete avoidance to avoid the problem of accidental collision. At the same time, a driving part is provided, which can complete intermittent power connection with the moving part.
