Description
Technical Field
[0001] The present application relates to the field of container door panel processing technology, and in particular to a container door panel conveying device. Background Art
[0002] A container is a group of vehicles that can transport packaged or unpackaged goods and facilitate loading, unloading, and handling with mechanical equipment. Container door panels are an essential component of a container. Their design ensures the safety and sealing of cargo while facilitating loading, unloading, and transportation.
[0003] In the related art, during the container processing process, the container door panels and the container door frame need to be welded and assembled. The container door panels are usually transported by a transport truck. During the transport of the container door panels, workers need to carry and stack the container door panels on the transport truck, and then push the transport truck to transport the container door panels.
[0004] Regarding the above-mentioned related technologies, the inventor believes that when the production line of container door panels and the production line of container door frames are located on different floors, transporting container door panels requires workers to transport the container door panels to the freight elevator using a transport truck, take the freight elevator to the floor where the container door frame is located, and then push the transport truck to transport the container door panels to the vicinity of the container door frame, and finally move the container door panels to the container door frame. The transfer efficiency is low and there is still room for improvement. Utility Model Content
[0005] In order to improve the problem of low transfer efficiency of container door panels when the production line of container door panels and the production line of container door frames are located on different floors, the present application provides a container door panel conveying device.
[0006] The container door panel conveying device provided in this application adopts the following technical solution:
[0007] A container door panel conveying device includes a lifting module for transporting container door panels and a welding platform for placing container door frames, the lifting module includes a lifting shaft, a lifting frame for placing container door panels and a driving source for controlling the lifting of the lifting frame, the lifting shaft is provided with a lifting cavity, the upper side of the lifting shaft is provided with an entrance for container door panels to enter the lifting cavity to the lifting frame, the lower side of the lifting shaft is provided with an exit for container door panels to leave the lifting cavity from the lifting frame, the lifting frame is arranged in the lifting cavity and slides up and down, the driving source is arranged above the lifting shaft, and the welding platform is arranged on a side of the lifting shaft with the exit to carry the container door panels leaving the lifting frame from the exit.
[0008] By adopting the above technical solution, workers push the container door panels from the entrance on the elevator shaft into the lifting frame in the lifting cavity, so that the container door panels move to the floor where the container door frames are located as the lifting frame slides up and down. The workers responsible for welding the container door panels and the container door frames then directly transfer the container door panels from the lifting frame to the welding table at the exit of the elevator shaft. Compared with workers loading the container door panels on a transport truck and taking the freight elevator for transfer, the setting of the elevator shaft and the lifting frame improves the transfer efficiency of transporting the container door panels to different floors.
[0009] Optionally, a plurality of rollers are rotatably connected to the lifting frame to abut against the lower side of the container door panel, and the plurality of rollers are horizontally arranged and parallel to the side wall of the lifting shaft on which the entrance is provided. The plurality of rollers cooperate to form a first contact surface that abuts against the lower side of the container door panel, and the first contact surface is inclined downward from the side close to the entrance to the side away from the entrance. A first limit block for abutting against the side of the container door panel away from the entrance is fixedly connected to the side of the lifting frame away from the entrance.
[0010] By adopting the above technical solution, compared with contacting the container door panel with the upper side of the lifting frame near the entrance and then using the push of the workers to make the container door panel slide onto the lifting frame, the roller contacts the lower side of the container door panel and transports the container door panel to the lifting frame by rolling, thereby reducing the friction force on the container door panel; on the other hand, due to the inclined setting of the first contact surface, the container door panel moves toward the side with a lower height of the first contact surface under the action of gravity, thereby reducing the force applied by the workers to push the container door panel onto the lifting frame, and further improving the convenience of the workers in pushing the container door panel to the top of the lifting frame; on the other hand, when the container door panel moves from the side away from the entrance to the side of the lifting frame away from the entrance, the container door panel contacts the side of the first limit block near the entrance, and the container door panel is restricted by the first limit block and cannot continue to move toward the side away from the entrance, thereby preventing the container door panel from falling off the lifting frame along the rolling direction of the roller, thereby improving the safety of the container door panel moving along the rolling direction of the roller.
[0011] Optionally, at least two first mounting brackets are fixedly connected to the bottom of the elevator shaft, and the first mounting brackets are perpendicular to the side wall of the elevator shaft where an exit is provided. A plurality of first rollers are rotatably connected to the first mounting brackets, and the plurality of first rollers are distributed along the length direction of the first mounting brackets. The plurality of first rollers cooperate to form a second contact surface that abuts against the lower side of the container door panel, and the second contact surface is inclined upward from the side close to the welding table to the side away from the welding table. A gap is provided on the elevator frame for avoiding the first mounting brackets. When the elevator frame moves to the bottom of the elevator shaft, the height of the roller is lower than the height of the first roller.
[0012] By adopting the above technical solution, when the lifting frame slides downward to the bottom of the lifting shaft, several first rollers are inserted into the gaps on the lifting frame. Since the height of the rollers is lower than the height of the first rollers, that is, the height of the first contact surface is lower than the height of the second contact surface, the container door panel is transferred from the rollers to the first rollers. Compared with the workers pulling the container door panel to slide along the length direction of the rollers to the welding table, the container door panel is transported by the rolling of the first rollers, which reduces the friction force of the container door panel when it is transferred to the welding table; and the inclined setting of the second contact surface makes the container door panel move to the side with lower height of the second contact surface under the action of gravity, that is, the container door panel moves to the side close to the welding table under the influence of gravity, which improves the convenience of transferring the container door panel from the lifting frame to the welding table.
[0013] Optionally, the first mounting frame extends from the exit to the outside of the elevator shaft, and the first mounting frame is provided with an escape opening for the elevator frame to avoid.
[0014] By adopting the above technical solution, when the lifting frame slides downward to the lower side of the lifting shaft, the side of the lifting frame close to the exit passes through the avoidance opening, so that there is no interference between the lifting frame and the first mounting portion; on the other hand, the distance between the side of the first mounting frame away from the lifting frame and the welding table is closer, so that the container door panel moves along the first roller to a position closer to the welding table and then disengages from the first roller, thereby improving the stability of the container door panel when being transferred to the welding table.
[0015] Optionally, a side of the lifting frame close to the exit is fixedly connected to a plurality of second limit blocks that abut against a side of the container door panel close to the exit, and the second limit block is rotatably connected to a number of second rollers equal to the number of the first mounting frame, and the plurality of second rollers cooperate to form a third contact surface that abuts against the lower side of the container door panel. When the lifting frame moves to the bottom of the lifting shaft, the second limit block provided with the second roller is located in the avoidance opening, and the third contact surface and the second contact surface are in the same plane.
[0016] By adopting the above technical solution, when the lifting frame moves to the bottom of the lifting shaft, the third contact surface and the second contact surface coincide with each other, the second roller is located above the avoidance opening, and the second roller cooperates with the first roller to form a complete conveyor chain, thereby improving the smoothness of the movement of the container door panel on the first roller.
[0017] Optionally, the first mounting bracket is fixedly connected to a first cylinder on one side extending outside the outlet, the piston rod of the first cylinder is set upward, and the side of the piston rod of the first cylinder away from the main body of the first cylinder is fixedly connected to a third limit block for abutting against the side of the container door panel close to the outlet.
[0018] By adopting the above technical solution, after the container door panel is transferred from the lifting frame to the first roller, the side of the container door panel close to the exit abuts against the side of the third limit block close to the lifting frame. The container door panel is restricted by the third limit block and cannot continue to move to the welding table, thereby avoiding the container door panel from moving to the welding table along the rolling direction of the first roller when the preparation work at the welding table is not completed, thereby interfering with the workers' welding work, and improving the stability of the workers in welding the container door panel and the container door frame; on the other hand, the setting of the first cylinder enables the workers to control the lifting and lowering of the third limit block by simply operating the switch of the first cylinder, thereby controlling the time for the container door panel to move from the first roller to the welding table, and improving the convenience of the workers in controlling the third limit block.
[0019] Optionally, a second mounting bracket is fixedly connected to the welding table, and there are two second mounting brackets parallel to each other. The opposite sides of the two second mounting brackets are rotatably connected to a plurality of third rollers that abut against the lower side of the container door frame. The plurality of third rollers are distributed along the length direction of the second mounting bracket to drive the container door frame to slide along the length direction of the second mounting bracket.
[0020] By adopting the above technical solution, compared with transporting the container door panel to the welding table, the workers place the container door frame on the second mounting rack and push the container door frame to slide on the second mounting rack, thereby reducing the work required by the workers to transport the container door panel to the welding table; on the other hand, the container door frame is placed on the upper side of the third roller, and the container door frame is transported by the rolling of the third roller, thereby reducing the friction force of the container door frame when sliding along the second mounting rack, and further improving the convenience of workers in moving the container door frame.
[0021] Optionally, opposite sides of the two second mounting frames are fixedly connected to second cylinders whose piston rods abut against the lower side of the container door frame, and the piston rods of the second cylinders face upward to lift or lower the container door frame.
[0022] By adopting the above technical solution, when the container door frame slides to the position for welding with the container door frame, the worker operates the second cylinder to extend the piston rod of the second cylinder upward, thereby lifting the container door frame. As a result, when the container door frame is subjected to external force, it is not easy to be displaced due to the friction between the container door frame and the piston rod of the second cylinder, thereby improving the stability of the container door frame placed on the second mounting frame.
[0023] Optionally, the welding table is hinged with at least two support frames for placing container door panels, and the welding table is also hinged with a third cylinder corresponding to the number of the support frames, and the piston rods of the third cylinders are hinged to the support frames one by one to drive the support frames to rotate to abut against the lower side of the container door panel.
[0024] By adopting the above technical solution, when the container door frame approaches or moves away from the welding table along the second mounting frame, the support frame is in a retracted state, thereby avoiding collision between the container door frame and the support frame and improving the safety of container door frame transportation; on the other hand, when the third cylinder drives the support frame to rotate to a raised state, the support rod provides supporting force for the container door panel, so that the container door panel and the container door frame are at the same height, which is convenient for workers to weld, thereby improving the convenience of workers in welding the container door panel and the container door frame.
[0025] Optionally, at least one fourth cylinder is fixedly connected to the support frame, the piston rod of the fourth cylinder is toward the side of the support frame away from the hinge of the welding table, and a support rod is fixedly connected to the piston rod of the fourth cylinder to abut against the lower side of the container door panel to lift or lower the container door panel.
[0026] By adopting the above technical solution, before operating the second cylinder to lower the third limit block, the fourth cylinder is operated to lift the support rod to reduce the height difference between the height of the first roller and the height of the support rod, thereby reducing the impact force received by the container door panel when it moves from the first roller to the support frame, and improving the safety of the container door panel when it moves from the first roller to the support frame.
[0027] In summary, this application includes at least one of the following beneficial technical effects:
[0028] 1. The installation of the lifting frame allows the container door panels to move to the floor where the container door frame is located as the lifting frame slides up and down, improving the efficiency of transporting container door panels to different floors;
[0029] 2. The setting of the roller enables the container door panel to move onto the lifting frame along the rolling direction of the roller, which improves the convenience for workers to push the container door panel onto the lifting frame;
[0030] 3. The provision of the first limit block prevents the container door panel from falling off the lifting frame along the rolling direction of the roller, thereby improving the safety of the container door panel moving along the rolling direction of the roller.

[0036] The following is combined with Figure 1-4 This application is described in further detail.
[0037] The embodiment of the present application discloses a container door panel conveying device.
[0038] Reference Figure 1 The container door panel conveying device includes a lifting module 1 and a welding table 2. The lifting module 1 is used to transport container door panels. The welding table 2 is used to place the container door frame and door panels for welding. The welding table 2 is located on one side of the lifting module 1, making it easy for workers to transfer the container door panels to the welding table 2 after the lifting module 1 transports them to the floor where the container door frame is located.
[0039] Reference Figure 1The lifting module 1 includes a lifting shaft 11, a lifting frame 12 and a driving source 13. The lifting shaft 11 has a lifting cavity 111 for the installation of the lifting frame 12. The upper side of the lifting shaft 11 has an entrance 112 for the container door panel to enter the lifting cavity 111; the lower side of the lifting shaft 11 has an exit 113 for the container door panel to leave the lifting cavity 111. In the embodiment of the present application, the driving source 13 is driven by a traction machine. In addition, the driving source 13 can also be other driving forms such as hydraulic drive and linear motor drive. The driving source 13 is fixedly connected to the top of the lifting shaft 11. The driving source 13 includes a driving motor 131, an output shaft 132 and a traction wheel 133. The driving motor 131 drives the output shaft 132 to rotate, and the traction wheel 133 is fixedly connected to the output shaft 132. The traction wheel 133 rotates with the rotation of the output shaft 132. The lifting frame 12 is slidably connected to the lifting shaft 11 to carry the container door panel to move synchronously. A steel cable 134 is wound around the traction sheave 133. One end of the cable 134 is fixedly connected to the lifting frame 12. The rotation of the traction sheave 133 controls the length of the cable 134 hanging near the lifting frame 12, thereby driving the lifting frame 12 to move upward or downward. To balance the weight of the lifting frame 12 borne by the traction sheave 133, the other end of the cable 134 is fixedly connected to the counterweight 14. This ensures that the tension on both sides of the traction sheave 133 is of similar magnitude, thereby reducing the burden on the drive motor 131.
[0040] Reference Figure 1 and Figure 2 The lifting frame 12 is rotatably connected to a plurality of rollers 121. These rollers 121 are arranged horizontally and parallel to the sidewall of the elevator shaft 11, which has an entrance 112. This reduces frictional forces experienced by the container door panel as it slides onto the lifting frame 12. The rollers 121 cooperate to form a first contact surface 1211 that abuts the underside of the container door panel. The height of the first contact surface 1211 gradually decreases from the side closest to the entrance 112 to the side further away from the entrance 112, causing the container door panel to slide toward the side further away from the entrance 112 due to gravity. To prevent the container door panel from falling from the side of the lifting frame 12 further away from the entrance 112, a first stopper 122 is fixedly connected to the side of the lifting frame 12 further away from the entrance 112.
[0041] Reference Figure 1 and Figure 3To facilitate the transfer of container door panels from exit 113 to the welding station 2, at least two first mounting brackets 15 are fixedly connected to the bottom of the elevator shaft 11. In this embodiment, two first mounting brackets 15 are used as an example. Both first mounting brackets 15 are parallel to the side wall of the elevator shaft 11 with the entrance 112. A plurality of first rollers 151 are rotatably connected to each first mounting bracket 15 to reduce friction as the container door panel slides along the first mounting brackets 15 onto the welding station 2. The first rollers 151 cooperate to form a second contact surface 1511 that abuts the underside of the container door panel. The height of the second contact surface 1511 gradually decreases from the side away from exit 113 to the side closer to exit 113, allowing the container door panel to slide toward the side closer to exit 113 and out of the elevator shaft 11 due to gravity. The side of the first mounting bracket 15 near exit 113 extends outside the elevator shaft 11, reducing the distance between the first mounting bracket 15 and the welding station 2. To prevent interference between the first mounting frame 15 and the lifting frame 12, both first mounting frames 15 are provided with an escape opening 152. A second stopper 123 is fixedly connected to the side of the lifting frame 12 near the exit 113. A second roller 1231 is rotatably connected to the side of the second stopper 123 away from the lifting frame 12. The second roller 1231 has a third contact surface 12311 formed to abut the underside of the container door panel. When the lifting frame 12 descends to the bottom of the elevator shaft 11, the second stopper 123 is positioned within the escape opening 152, the second roller 1231 abuts the underside of the container door panel, and the third contact surface 12311 and the second contact surface 1511 coincide, allowing the container door panel to slide out of the lifting frame 12 without being restricted by the second stopper 123. A first cylinder 153 is fixedly connected to the first mounting frame 15, with its piston rod facing upward. In order to control the time for the container door panel to slide onto the welding table 2 , a third limit block 1531 is fixedly connected to the piston rod of the first cylinder 153 , so that the lifting and lowering of the third limit block 1531 can be controlled by operating the first cylinder 153 .
[0042] Reference Figure 4To facilitate transport of the container door frame, the welding table 2 is fixedly connected to two second mounting frames 21. Several third rollers 211 are rotatably connected to the two second mounting frames 21, allowing the container door panel to be placed and slide on these third rollers 211. A second cylinder 212 is fixedly connected to the second mounting frames 21. The piston rod of the second cylinder 212 faces upward, raising or lowering the container door frame and thereby positioning the container door frame on the welding table 2. The welding table 2 is hingedly connected to at least two support frames 22 and a corresponding number of third cylinders 23. In this embodiment, there are two support frames 22 and four third cylinders 23. The piston rods of the third cylinders 23 are hingedly connected to each of the two support frames 22, driving the support frames 22 to rotate and support the container door panel. At least one fourth cylinder 221 is fixedly connected to each support frame 22. In this embodiment, there are two fourth cylinders 221 fixedly connected to each support frame 22. The piston rod of the fourth cylinder 221 faces upward, and a support rod 2211 is fixedly connected to the piston rod of the fourth cylinder 221 for contacting the lower side of the container door panel. By manipulating the fourth cylinder 221 to control the raising and lowering of the support rod 2211, the height of the container door panel on the welding table 2 is further controlled.
[0043] The door panel of the container is pushed into the lifting cavity 111 from the entrance 112 of the lifting shaft 11, and the lower side of the door panel of the container abuts on the roller 121. The door panel of the container slides along the rolling direction of the roller 121 under the action of gravity to the side of the lifting frame 12 away from the entrance 112. At this time, the side of the door panel of the container away from the entrance 112 abuts on the first limit block 122; the driving source 13 is operated to drive the lifting frame 12 to move the container door panel downward. When the lifting frame 12 moves to the lower side of the lifting shaft 11, the side of the lifting frame 12 near the exit 113 passes through the avoidance opening 152 of the first mounting frame 15. The part of the first mounting frame 15 located in the lifting shaft 11 passes through the gap on the lifting frame 12. At this time, the oblique side of the container door panel abuts on the first roller 151, and the door panel of the container slides along the first roller 151 in the direction close to the exit 113 under the action of gravity. The side of the container door panel close to the exit 113 abuts On the second limit block 123; when the lifting frame 12 continues to move downward until the third contact surface 12311 and the second contact surface 1511 coincide with each other, the container door panel is no longer restricted by the second limit block 123 and the third roller 211 and slides toward the side close to the welding table 2. At this time, the container door panel abuts against the third limit block 1531; after the container door frame slides to a suitable position along the third roller 211, the second cylinder 212 is operated to lift the container door frame to prevent the container door frame from continuing to slide; The third cylinder 23 drives the support frame 22 to rotate and rise, and then operates the fourth cylinder 221 to drive the support rod 2211 to rise, and then operates the first cylinder 153 to drive the third limit block 1531 to descend, so that the container door panel slides from the first roller 151 to the support rod 2211, and then operates the fourth cylinder 221 to drive the support rod 2211 to drive the container door panel to descend, so that the upper side of the container door panel and the upper side of the container door frame are aligned, and finally the container door panel and the container door frame are welded.
[0044] The above are all preferred embodiments of the present application, and are not intended to limit the scope of protection of the present application. Therefore, any equivalent changes made based on the structure, shape, and principle of the present application should be included in the scope of protection of the present application.
