Description

Technical Field

[0001] This utility model relates to the field of door panel transportation and storage technology, specifically, to a door panel transportation and storage device. Background Technology

[0002] After the control cabinet door panels are painted, they are often vertically stacked (e.g., 10 or 20 panels) on wooden pallets to save storage space. This method easily leads to scratches on the paint coating and even deformation of the door panels. In severe cases, reshaping and repainting are required, directly affecting product quality and delivery cycle. To prevent stacking damage while also ensuring space efficiency and convenient and labor-saving retrieval operations, existing technologies typically employ multi-layer placement platforms. This platform consists of multiple downward-sloping support bars fixedly installed within the vehicle frame. Each layer can hold one or more door panels, effectively avoiding direct crushing damage between door panels, and the vehicle body is movable for easy transportation.

[0003] However, door panels come in various sizes. When the spacing between adjacent support strips is less than the width of the door panel, the door panel may fall and be damaged due to the insufficient spacing, making it difficult to place it stably. If a large number of support strips are installed to reduce the spacing in order to accommodate small door panels, it will significantly increase the weight of the vehicle frame and hinder the flexible transport of the door panels. Therefore, the ideal solution is to dynamically adjust the number of support strips according to the width of the door panel (i.e., the spacing is adjustable). However, since there are many platform layers, reducing the spacing requires adding additional support strips to each layer. In the existing technology, these support strips can only be fastened to the vehicle frame one by one with bolts. The installation process requires layer-by-layer operation, which is labor-intensive and inefficient. Utility Model Content

[0004] The purpose of this utility model is to provide a door panel transportation and storage device to solve the problems mentioned in the background art above:

[0005] In existing technologies, support bars can only be fastened to the vehicle frame one by one with bolts. The installation process requires layer-by-layer operation, which is labor-intensive and inefficient.

[0006] To address the above problems, this utility model aims to provide a door panel transportation and storage device, comprising a frame. A plurality of horizontally arranged positioning rods are vertically arrayed and fixedly installed on one side of the frame. A plurality of inclined fixed support bars are fixedly installed on opposite sides of the frame at positions corresponding to each positioning rod. The lower ends of the fixed support bars are fixedly connected to the upper sidewall of the corresponding positioning rod. A plurality of support components are horizontally arrayed inside the frame. Each support component includes a vertically arranged longitudinal beam. A movable support bar is inclinedly hinged to one side of the longitudinal beam at a position corresponding to each positioning rod. A stop assembly is provided on the upper side of the lower ends of both the movable and fixed support bars. A flipping mechanism is provided on the longitudinal beam for synchronously driving all movable support bars to rotate around their respective hinge points. A locking assembly is also provided on the longitudinal beam. When the flipping mechanism drives the movable support bar to rotate its end away from the longitudinal beam to a position contacting the upper sidewall of the corresponding positioning rod, the upper sidewalls of the fixed and movable support bars at the same height are on the same inclined plane. At this time, the locking assembly restricts the position of the longitudinal beam on the frame.

[0007] As a further improvement to this technical solution, the material blocking assembly includes a baffle hinged to a fixed support bar and a movable support bar. A torsion spring is sleeved on the hinge shaft of the baffle, and the two ends of the torsion spring abut against the baffle and the fixed support bar or the movable support bar, respectively.

[0008] As a further improvement to this technical solution, the flipping mechanism includes a movable frame that is vertically slidably disposed on the side of the longitudinal beam near the movable support bar. Inside the movable frame, a partition is fixedly disposed at a position corresponding to each movable support bar, and the partition contacts the lower side wall of the corresponding movable support bar.

[0009] As a further improvement to this technical solution, the longitudinal beam is provided with a movable groove, and the flipping mechanism further includes a slider that is slidably disposed inside the movable groove, with one end of the slider fixedly disposed on one of the partitions.

[0010] As a further improvement to this technical solution, the flipping mechanism also includes an assembly frame fixedly disposed on the side of the longitudinal beam away from the movable support bar, and a threaded rod is vertically rotatably disposed inside the assembly frame, with the slider slidably disposed on the threaded rod.

[0011] As a further improvement to this technical solution, the frame includes two horizontally arranged crossbeams. Several insertion stations are arranged in a horizontal array on the side of the two crossbeams that are close to each other. Each insertion station includes two limiting plates fixedly arranged on the crossbeams. An insertion gap is formed between the two limiting plates. The two ends of the longitudinal beam are respectively in contact with the side of the two crossbeams that are close to each other, and the two ends of the longitudinal beam are respectively located in two corresponding insertion gaps.

[0012] As a further improvement to this technical solution, the snap-fit ​​assembly includes two blocks that are respectively fixedly disposed at both ends of the longitudinal beam on the side away from the movable support bar, and the blocks are in contact with the outer wall of the crossbeam.

[0013] As a further improvement to this technical solution, when the assembly frame moves vertically downward, causing the end of the movable support bar away from the longitudinal beam to contact the upper side wall of the corresponding positioning rod, the movable frame contacts the side of the crossbeam away from the stop block.

[0014] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0015] 1. The door panel transport and storage device inserts both ends of the longitudinal beam into the corresponding insertion gaps, ensuring that the stop block and the side of the crossbeam away from the positioning rod are in contact. Then, the threaded rod is rotated to drive the slider to move the movable frame downward, causing the movable support bar to rotate downward around the hinge axis under the action of gravity until its lower side wall contacts the corresponding positioning rod, forming an inclined placement plane together with the upper side wall of the fixed support bar. At the same time, the lower end of the movable frame moves to below the longitudinal beam, cooperating with the stop block to fix the longitudinal beam to the frame. This realizes the rapid installation of the support component as a prefabricated integrated structure. By installing the support component, the spacing between adjacent movable support bars on all placement planes can be reduced simultaneously, allowing operators to stably place door panels with smaller widths on the inclined placement plane formed by the movable support bars and the fixed support bars. This makes the device suitable for door panels of various sizes. Attached Figure Description

[0030] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0031] Example 1

[0032] Please see Figure 1 As shown, the purpose of this embodiment is to provide a door panel transportation and storage device, including a frame 1. The frame 1 is a cuboid structure composed of multiple straight rods, including two horizontally arranged crossbeams 13. Rollers are fixedly installed on the lower side wall of the frame 1 near the four corners, two of which are directional wheels and the other two are omnidirectional wheels, which facilitates the operator to push the device to the required work position. The omnidirectional wheels are equipped with brakes to fix the device at the work position. Lifting rings are fixedly installed on the upper side wall of the frame 1 near the four corners. If the device needs to be transported over a long distance, hoisting equipment can be used in conjunction with the lifting rings to lift the device onto a vehicle for transportation.

[0033] Reference Figure 2On the side of frame 1 away from the crossbeam 13, several horizontally arranged positioning rods 11 are fixedly arranged in a vertical array. On both sides of frame 1, several inclined fixed support bars 3 are fixedly arranged at positions corresponding to each positioning rod 11. The distance between two adjacent fixed support bars 3 is greater than the thickness of the door panel. Several fixed support bars 3 located on the same side of frame 1 form a group. Several support components 2 are arranged in a horizontal array inside frame 1. Two groups of fixed support bars 3 are located on both sides of the crossbeam 13. The lower end of the fixed support bar 3 is fixedly connected to the upper side wall of the corresponding positioning rod 11. At the same time, several support components 2 are arranged in a horizontal array inside frame 1. The support components 2 are located between the two groups of fixed support bars 3. The support components 2 are used to cooperate with the fixed support bars 3 to place the door panel.

[0034] Reference Figure 5 The support assembly 2 includes a vertically arranged longitudinal beam 21. Both ends of the longitudinal beam 21 are in contact with the sides of two crossbeams 13 that are close to each other. On one side of the longitudinal beam 21, at the position corresponding to each positioning rod 11, a movable support bar 23 is inclinedly hinged. The distance between two adjacent movable support bars 23 is greater than the thickness of the door panel, and the end of the movable support bar 23 near the longitudinal beam 21 is at the same height as the upper end of the fixed support bar 3. The longitudinal beam 21 is provided with a flipping mechanism 22 for synchronously driving all movable support bars 23 to rotate around their respective hinge points. When the flipping mechanism 22 drives the movable support bar 23 to rotate the end away from the longitudinal beam 21 to the position that contacts the upper side wall of the corresponding positioning rod 11, the upper side walls of the fixed support bar 3 and the movable support bar 23 at the same height are on the same inclined plane. A baffle assembly is provided on the upper side of the lower end of both the movable support bar 23 and the fixed support bar 3.

[0035] After the operator places the door panel on the upper surface of the fixed support bar 3 and the movable support bar 23, the baffle assembly prevents the door panel from sliding down the inclined plane, thus stabilizing the door panel. This method of placing the door panel at an incline makes it easy for the operator to put it in and take it out, and also prevents the door panel from accidentally sliding down.

[0036] The structure of the baffle assembly is detailed below, referring to... Figure 3 The baffle assembly includes a baffle 4 hinged to a fixed support bar 3 and a movable support bar 23. In the initial state, the baffle 4 is perpendicular to the upper sidewalls of the movable support bar 23 and the fixed support bar 3, and the height of the baffle 4 is less than the gap between two adjacent fixed support bars 3. A torsion spring 5 is sleeved on the hinge shaft of the baffle 4. The torsion spring 5 is located on the side of the baffle 4 near the crossbeam 13, and the two ends of the torsion spring 5 abut against the baffle 4 and the fixed support bar 3 or the movable support bar 23, respectively.

[0037] As the operator places the door panel onto the upper sidewalls of the movable support bar 23 and the fixed support bar 3 from bottom to top, the door panel will contact and push the baffle 4 to rotate downwards, causing the torsion spring 5 to undergo elastic deformation (energy storage). This action allows the door panel to move smoothly to the upper sidewalls of the movable support bar 23 and the fixed support bar 3. When the door panel is fully in place (i.e., placed at the predetermined position on the upper sidewalls of the movable support bar 23 and the fixed support bar 3), its lower end passes the initial blocking position of the baffle 4. The baffle 4 returns to its initial state under the action of the torsion spring 5. After returning to its initial state, the lower sidewall of the baffle 4 contacts the upper sidewall of the fixed support bar 3 or the movable support bar 23, thereby restricting the baffle 4 from rotating away from the torsion spring 5. Therefore, when the door panel attempts to slide down along the upper sidewalls of the movable support bar 23 and the fixed support bar 3 and comes into contact with the baffle 4, the baffle 4 will form a blockage, preventing the door panel from continuing to slide down and ensuring that the door panel is stably placed on the upper sidewalls of the movable support bar 23 and the fixed support bar 3.

[0038] The structure of the flipping mechanism 22 is described in detail below, with reference to... Figures 5-8 The flipping mechanism 22 includes a movable frame 221 vertically slidably disposed on the side of the longitudinal beam 21 near the movable support bar 23. Inside the movable frame 221, a partition 222 is fixedly disposed at a position corresponding to each movable support bar 23. The partition 222 contacts the lower sidewall of the corresponding movable support bar 23. The distance between two adjacent partitions 222 is greater than the thickness of the movable support bar 23, allowing the movable support bar 23 to rotate freely within the distance between adjacent partitions 222. A movable groove 212 is provided on the longitudinal beam 21. The flipping mechanism 22 also includes a sliding... A slider 225 is set inside the movable slot 212. One end of the slider 225 is fixedly set on one of the partitions 222. The flipping mechanism 22 also includes an assembly frame 223 fixedly set on the side of the longitudinal beam 21 away from the movable support bar 23. A threaded rod 224 is vertically rotatably set inside the assembly frame 223. The slider 225 is slidably set on the threaded rod 224. The upper end of the threaded rod 224 rotatably passes through the upper side wall of the assembly frame 223 and is coaxially fixedly set with a bolt head, which makes it convenient for operators to use tools such as electric screwdrivers to rotate the threaded rod 224.

[0039] When the operator rotates the threaded rod 224, the threaded engagement between the threaded rod 224 and the slider 225 drives the slider 225 to move along the axis of the threaded rod 224. The slider 225 drives the movable frame 221 and all the partitions 222 to move synchronously. When the movable frame 221 moves vertically upward, the partition 222 pushes the corresponding movable support bar 23 to rotate upward around its hinge axis. When the movable frame 221 moves vertically downward, the partition 222 moves downward synchronously, and the movable support bar 23 rotates downward around its hinge axis under the action of gravity. During this process, the movable support bar 23 always maintains contact with the corresponding partition 222, thereby achieving the purpose of synchronously driving all the movable support bars 23 to rotate.

[0040] To fix the position of the longitudinal beam 21 on the frame 1 and ensure the stability of the movable support bar 23 during operation, a snap-fit ​​assembly is provided on the longitudinal beam 21. The snap-fit ​​assembly is used to restrict the position of the longitudinal beam 21 on the frame 1. The structure of the snap-fit ​​assembly is detailed below. The snap-fit ​​assembly includes two blocks 211 that are respectively fixedly installed on the side away from the movable support bar 23 at both ends of the longitudinal beam 21. The blocks 211 are in contact with the outer wall of the crossbeam 13. When the assembly frame 223 moves vertically downward, so that the end of the movable support bar 23 away from the longitudinal beam 21 contacts the upper side wall of the corresponding positioning rod 11, the movable frame 221 contacts the side of the crossbeam 13 away from the blocks 211. At this time, the movable frame 221 and the blocks 211 cooperate to restrict one degree of freedom of the longitudinal beam 21 in the horizontal direction.

[0041] Reference Figure 4 Several insertion stations are arranged in a horizontal array on the side where the two crossbeams 13 are close to each other. Each insertion station includes two limiting plates 12 fixedly set on the crossbeams 13. An insertion gap is formed between the two limiting plates 12, and the two ends of the longitudinal beam 21 are respectively located in two corresponding insertion gaps. The limiting plates 12 on both sides of the insertion gap restrict another degree of freedom of the longitudinal beam 21 in the horizontal direction. Since the two ends of the longitudinal beam 21 are in contact with the side where the two crossbeams 13 are close to each other, the two crossbeams 13 together restrict the degree of freedom of the longitudinal beam 21 in the vertical direction. By restricting the three degrees of freedom, the longitudinal beam 21 can be firmly fixed on the frame 1, thereby ensuring the stability of the movable support bar 23 when supporting the door panel.

[0042] It is worth noting that the support component 2 is a prefabricated integrated structure. In the initial state, the movable support bar 23 is in a horizontal position, and the movable frame 221 is completely located on one side of the longitudinal beam 21. This design makes it easy for the operator to insert the movable support bar 23 into the gap between the adjacent positioning rods 11 and insert the longitudinal beam 21 into the frame 1 as a whole.

[0043] When this device is in use, some insertion stations are usually idle. When it is necessary to load door panels of special length (such as those with a width smaller than the distance between two adjacent movable support bars 23 of the same height) into the frame 1, the support assembly 2 can be added to the idle insertion stations. The addition process is as follows: First, insert both ends of the longitudinal beam 21 into the corresponding insertion gaps, ensuring that the stop block 211 contacts the side of the crossbeam 13 away from the positioning rod 11. At this time, all movable support bars 23 are located between adjacent positioning rods 11. Then, rotate the threaded rod 224 to drive the slider 225 to move the movable frame 221 downward. During this process, several partitions 222 fixed on the movable frame 221 move downward simultaneously, causing the movable support bars 23 to move downward. Under the action of gravity, it rotates downward around the hinge axis until its lower side wall contacts the corresponding positioning rod 11. At this time, the upper side wall of the movable support bar 23 and the fixed support bar 3 together form an inclined placement plane. At the same time, the lower end of the movable frame 221 moves to the bottom of the longitudinal beam 21 and cooperates with the stop block 211 to restrict the movement of the longitudinal beam 21 in a certain direction in the horizontal plane, thereby reliably fixing the longitudinal beam 21 to the frame 1. This process realizes the rapid installation of the support component 2. By installing the support component 2, the distance between adjacent movable support bars 23 of the same height can be reduced, so that the operator can stably place the door panel with a smaller width on the inclined placement plane formed by the movable support bar 23 and the fixed support bar 3.
