Description

Technical Field

[0001] This utility model relates to the field of container manufacturing technology, and in particular to a container welding and turning device. Background Technology

[0002] Containers are assembled into rectangular box-like components by welding door panels. Welding, repair, and grinding are required on both sides. Currently, welding, repair, and grinding are carried out in batches, side by side, using a platform, which is time-consuming and labor-intensive. Furthermore, there is a large backlog of work-in-process inventory on-site, which is detrimental to on-site management and lean production requirements. The assembly and welding process for container door frames mainly includes: door panel assembly, door panel corrugated welding, and welding of the door panel frame to the long straight seam of the corrugated board.

[0003] Patent CN218695647U discloses a container door frame welding and turning machine, including a base plate, a support frame on the upper part of the base plate, a turntable on the upper part of the support frame, and a conveying section inside the turntable. The conveying section includes two parallel conveying frames, and several conveying rollers are arranged on the inner side of the conveying frames, with each conveying roller corresponding to the other. Turning rollers are arranged inside the support frame, and the outer edge of the turntable contacts the turning rollers. There are two support frames and two turntables, located at both ends of the conveying section and fixedly connected to both ends of the conveying section. Door panels from the upper station are manually assisted in being conveyed to the turning station. The turning machine is equipped with non-powered rollers and can rotate 180° left and right, allowing manual repositioning for welding the door panel column welds.

[0004] The aforementioned patents still have the following technical defects: the door frame needs to be lifted to a designated height for flipping, which is difficult to handle manually and takes up a lot of space, thus limiting its use. Utility Model Content

[0005] The purpose of this invention is to address the problems existing in the background technology by proposing a container welding and turning device.

[0006] The technical solution of this utility model is a container welding and turning device, comprising:

[0007] Two movable supports, each with multiple rollers mounted at its bottom, and a linear drive mechanism connecting their upper ends;

[0008] Two sets of clamping assemblies are symmetrically arranged. Each clamping assembly includes a rotating plate, a support base, an upper clamping block, and a second electric push rod. The support base is connected to the bottom end of the rotating plate and has a wedge-shaped structure. The upper clamping block is slidably mounted on the rotating plate. The second electric push rod is mounted on the rotating plate and its output shaft is connected to the upper clamping block by a connecting frame.

[0009] Two lifting plates are respectively located at the positions of the movable brackets on both sides. Each movable bracket on both sides is equipped with a first electric push rod for driving the corresponding side lifting plate to move. A mounting shaft is installed on the rotating plate, and the rotating plate is rotatably mounted on the corresponding side lifting plate through the mounting shaft. A rotary drive assembly for driving the mounting shaft to rotate is installed on the lifting plate.

[0010] Preferably, the upper end of the rotating plate is connected to an upper support pad, which has a wedge-shaped structure.

[0011] Preferably, limit side plates are connected to the same side of both rotating plates.

[0012] Preferably, the rotary drive assembly includes a third electric push rod, a rack, and a gear ring, wherein the third electric push rod is mounted on the lifting plate, the rack is connected to the output shaft of the third electric push rod, and the gear ring is mounted on the outer periphery of the mounting shaft and meshes with the rack.

[0013] Preferably, the linear drive mechanism is either a scissor lift or an electric push rod.

[0014] Preferably, the height of the movable bracket is greater than the length of any side of the rotating plate.

[0015] Compared with the prior art, the present invention has the following beneficial technical effects: the present invention can realize the flipping, lifting and moving of the frame, which is more convenient to operate. There is no need to manually carry it during the whole process, which reduces the difficulty and cumbersomeness of operation. In addition, the whole structure can be folded and retracted, which occupies less space. Attached Figure Description

Detailed Implementation

[0019] Example 1

[0020] like Figures 1-3 As shown in the figure, the container welding and turning device proposed in this embodiment includes two movable supports 1, two lifting plates 11 and two sets of clamping components.

[0021] Multiple rollers 16 are installed at the bottom of both movable supports 1, and a linear drive mechanism 2 is connected between the upper ends of the two movable supports 1. The linear drive mechanism 2 is either a scissor lift or an electric push rod.

[0022] Two sets of clamping components are symmetrically arranged. The clamping components include a rotating plate 3, a support base 4, an upper clamping block 5, and a second electric push rod 8. The support base 4 is connected to the bottom end of the rotating plate 3 and has a wedge-shaped structure. The upper clamping block 5 is slidably mounted on the rotating plate 3. The second electric push rod 8 is mounted on the rotating plate 3 and its output shaft is connected to the upper clamping block 5 by a connecting frame 9.

[0023] Two lifting plates 11 are respectively located at the positions of the two movable supports 1 on both sides. Each movable support 1 on both sides is equipped with a first electric push rod 6 for driving the corresponding side lifting plate 11 to move. A mounting shaft 15 is mounted on the rotating plate 3, and the rotating plate 3 is rotatably mounted on the corresponding side lifting plate 11 through the mounting shaft 15. A rotary drive assembly for driving the mounting shaft 15 to rotate is mounted on the lifting plate 11. The rotary drive assembly includes a third electric push rod 12, a rack 13, and a gear ring 14. The third electric push rod 12 is mounted on the lifting plate 11, the rack 13 is connected to the output shaft of the third electric push rod 12, and the gear ring 14 is mounted on the outer periphery of the mounting shaft 15 and meshes with the rack 13. The third electric push rod 12 works to drive the rack 13 to move. The movement of the rack 13 drives the gear ring 14 to rotate, thereby driving the rotating plate 3 to rotate.

[0024] Both rotating plates 3 are connected to limit side plates 10 on the same side, driving the rotating plates 3 to rotate towards the side adjacent to the limit side plate 10. The limit side plate 10 can limit the frame and prevent the frame from slipping. The height of the movable bracket 1 is greater than the length of any side of the rotating plate 3. This setting allows the rotating plates 3 to rotate smoothly.

[0025] Specifically, when flipping the frame that makes up the container, the equipment is moved to the position of the frame, so that the two sets of clamping components are located on both sides of the frame. Then, the linear drive mechanism 2 drives the two moving brackets 1 to move closer to each other, which in turn drives the two support bases 4 to move closer to each other. The pointed ends of the support bases 4 are inserted into the bottom of the frame. As the support bases 4 move, they gradually lift the frame. Then, the second electric push rod 8 is activated to drive the upper clamping block 5 to move downward, thus clamping the upper end of the frame. Next, the first electric push rod 6 drives the clamping components to move upward, which in turn moves the frame upward. Then, the rotation drive component drives the clamping components to rotate 180 degrees, thus flipping the frame. Then, the operator can perform welding work on the other side of the frame. After the frame is flipped, the first electric push rod 6 drives the frame to move downward to the limited position. Finally, the limit on the frame is released, and the frame falls to the ground. This equipment has the functions of flipping, lifting, and moving, and the operation is relatively convenient. The frame does not need to be manually moved throughout the process.

[0026] Example 2

[0027] like Figure 3 As shown, in this embodiment, a container welding and turning device is proposed. Compared with the first embodiment, in this embodiment, the upper end of the rotating plate 3 is connected to an upper support pad 7, which is a wedge-shaped structure. After the frame is rotated 180 degrees, the first electric push rod 6 drives the frame to move downward to the set position. Then, the second electric push rod 8 is activated to drive the upper clamping block 5 to move to release the frame. Finally, the linear drive mechanism 2 drives the two moving supports 1 to move away from each other. At this time, the frame falls downward onto the upper support pad 7, which can play a buffering role. As the upper support pads 7 on both sides continue to move, the frame gradually and slowly falls to the ground.

[0028] The embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited thereto. Various changes can be made within the scope of knowledge possessed by those skilled in the art without departing from the spirit of the present invention.
