Description

Technical Field

[0001] The present invention relates to the field of plate transfer racks, and in particular to an anti-dumping plate transfer rack. Background Art

[0002] Crystalline silicon panels are high-performance panels made from silicon through a special process. They are fireproof, moisture-proof, environmentally friendly, and durable, making them widely used in architectural decoration, home customization, and industrial applications. Crystalline silicon panels are thin sheets made of silicon and are fragile. They require special care during handling and use to avoid breakage. At present, crystalline silicon panels are generally transported by A-shaped transport racks when being transported. For example, the Chinese utility model patent (application number: CN202223061651.0) discloses a "transport rack for transporting tempered glass", which includes a base, and the four corners of the bottom of the base are respectively provided with universal wheels for easy pushing. A tripod is provided in the middle position of the upper end of the base for the glass to lean on. The tripod is provided with multiple supporting beams. The bottom two sides of the tripod are respectively provided with a tray frame for supporting the glass. The tray frame is provided with multiple supporting vertical beams. The tripod and the tray frame are set at a 90° angle to facilitate the neat arrangement of the glass. The two sides of the tripod are extended by pulling and extending. The tray frame staggers the laminated glass by changing the angle between the tray frame and the tripod. The above-mentioned device can be adjusted according to the actual length of the loaded glass to increase the protection of the glass. At the same time, the device can stagger multiple pieces of glass to facilitate the transporter to take a single piece or a small amount. However, since its tripod is fixed on the base, when transporting a small amount of plates, in order to maintain the center of gravity of the transportation, the plates still need to be evenly placed on both sides of the tripod, which is time-consuming and labor-intensive, reduces the efficiency of plate transportation, and has low practicality.

DETAILED DESCRIPTION

[0019] In order to enable those skilled in the art to better understand the solutions of the present invention, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts should fall within the scope of protection of the present invention.

[0020] The present invention will be further described below with reference to the embodiments.

[0021] Example: Refer to Figures 1 to 7 , an anti-dumping plate transfer rack for transferring crystalline silicon plates, comprising a base frame 100, an A-shaped frame 200 movably provided on the base frame 100, the A-shaped frame 200 being used to place the crystalline silicon plates, the base frame 100 being used to cooperate with a transfer vehicle or a forklift, the specific operation of which will not be described in detail here; In order to solve the problem that the plate transfer rack in the prior art has a fixed bracket position, when transporting a small amount of plates, in order to maintain the center of gravity of the transportation, the plates still need to be evenly placed on both sides of the bracket, which is time-consuming and labor-intensive, reduces the efficiency of plate transportation, and has low practicality, in the present application, the A-frame 200 for placing the crystalline silicon plates is movably set on the base frame 100. The purpose of such a setting is to be able to change the center of gravity of the plate on the base frame when it is placed on one side of the A-frame 200. Specifically, a linear drive mechanism 300 is provided, which is installed on the base frame 100 and is used to drive the A-frame 200 to perform reciprocating linear motion along the width direction of the base frame 100. Then, when transporting a small amount of crystalline silicon plates, the position of the A-frame 200 supporting the crystalline silicon plates on the base frame 100 can be driven, and then all the A-frames 200 can be placed on one side of the A-frame 200, and the center of the whole can be located in the middle position of the base frame 100, thereby improving its stability during transportation; Specifically, the linear drive mechanism 300 includes a first threaded rod 301 installed on the base frame 100. Preferably, the first threaded rod 301 is installed in the middle position of the base frame 100. Side plates 101 are provided on both sides of the base frame 100 for installing the first threaded rod 301. The upper part of the side plates 101 protrudes from the base frame 100 to facilitate the installation of the first threaded rod 301. The bottom of the A-shaped frame 200 has a bottom plate 201. A threaded seat 302 adapted to the first threaded rod 301 is installed at the bottom end of the bottom plate 201. One end of the first threaded rod 301 passes through the side plate 101 and has a driving seat 303. The driving seat 303 has a card slot 304 for self-rotation. Both sides of the base frame 100 have a slide groove 102. Slide seats 305 adapted to the slide groove 102 are respectively installed on both sides of the bottom end of the bottom plate 201. The slide groove 102 cooperates with the slide seat 305 to guide the linear movement of the threaded seat 302. During specific use, the first threaded rod 301 is driven to rotate by an external operating rod (the operating rod is adapted to the card slot 304), and the threaded seat 302 is guided by the sliding grooves 102 on both sides and the sliding seat 305, so that the threaded seat 302 is made to move linearly along the first threaded rod 301, thereby driving the bottom plate 201 and the A-shaped frame 200 to move linearly, thereby achieving the purpose of adjusting the position of the A-shaped frame 200 on the base frame 100.

[0022] Furthermore, it also includes a pair of side base frames 400, which are symmetrically arranged at the bottom of both sides of the A-shaped frame 200, wherein one side base frame 400 is fixedly connected to the bottom of the A-shaped frame 200, and the other side base frame 400 is rotatably connected to the bottom of the A-shaped frame 200, and the side base frames 400 are vertically connected to the bottom of the A-shaped frame 200, corresponding to the side edges of the crystalline silicon plate, so that it can be better placed on the A-shaped frame 200 and the side base frames 400. Through the connection between the side base frames 400 and the A-shaped frame 200, and because the side faces of the A-shaped frame 200 are inclined surfaces, the plates placed on the side base frames 400 will be inclined on the A-shaped frame 200, making the transportation of the plates more stable.

[0023] Considering that when the A-frame 200 is moved to change its center of gravity, the side chassis 400 on one side of the A-frame 200 will protrude from the base frame 100, thereby expanding the horizontal space occupied by the base frame 100, which is not conducive to transporting plates in places with narrow aisles. Therefore, the driven mechanism 500 provided in the present application operates synchronously with the linear drive mechanism 300 to drive the side chassis 400 rotatably connected to the bottom of the A-frame 200 to rotate toward the top of the A-frame 200, so that the side chassis 400 does not protrude from the base frame 100, thereby preventing it from protruding from the base frame 100 due to the displacement of the A-frame 200, thereby expanding the overall horizontal space and facilitating the transportation process of the plates; Specifically, the driven mechanism 500 includes a second threaded rod 501 installed on both sides of the base 100, the second threaded rod 501 is fixed between the two side plates 101, a threaded sleeve 502 adapted to the second threaded rod 501 is installed on the bottom plate 201, a first bevel gear 503 is installed at the end of the threaded sleeve 502, a connecting shaft 505 is installed at the bottom of the bottom plate 201, a second bevel gear 504 adapted to mesh with the first bevel gear 503 is installed at the outer end of the connecting shaft 505, and the inner end of the connecting shaft 505 is fixed to the end of the side chassis 400. When in use, through the first When the threaded rod 301 rotates to drive the base plate 201 to move with the A-frame 200, the threaded sleeve 502 moves synchronously with the base plate 201. Since the second threaded rod 501 is fixed and the threaded sleeve 502 is arranged to rotate on the base plate 201, the threaded sleeve 502 will rotate with the first bevel gear 503 under the drive of the second threaded rod 501. Correspondingly, the second bevel gear 504 will engage with the first bevel gear 503 to drive the connecting shaft 505 and the side base frame 400 that moves synchronously with the A-frame 200 to rotate upward, thereby achieving the purpose of retracting the side base frame 400.

[0024] Furthermore, the threaded sleeve 502 is installed on the slide 305 and rotates thereon. The side of the slide 305 has an extension seat 306, and the connecting shaft 505 is installed on the extension seat 306 to facilitate the meshing installation of the first bevel gear 503 and the second bevel gear 504. The end of the side chassis 400 has a connecting seat 402 for fixed connection of the connecting shaft 505. The connecting shaft 505 is fixed to the connecting seat 402 by fasteners, and the side chassis 400 rotates around the connecting shaft 505 as the axis.

[0025] Furthermore, the side of the bottom plate 201 is provided with an avoidance groove 403 for the side base frame 400 to rotate upward, thereby preventing the bottom plate 201 from blocking the side base frame 400. At the same time, the side base frame 400 can be tightly attached to the bottom of the A-shaped frame 200, which is conducive to the placement of the crystalline silicon plate.

[0026] Preferably, a group of pulleys 401 are installed at the bottom of the side chassis 400, and the pulleys 401 are arranged in a linear array in the middle position of the side chassis 400, so that the side chassis 400 fixedly connected to the A-frame 200 can move synchronously with the bottom plate 201 and the A-frame 200, and the side chassis 400 rotatably connected to the A-frame 200 rotates, that is, the pulleys 401 can support the side chassis 400.

[0027] Preferably, the outer end of the side chassis 400 and the side plate 101 are located on the same horizontal plane, so that more crystalline silicon plates can be placed on the side chassis 400 without protruding from the side plate 101 .

[0028] Preferably, the connection between the inner end of the side chassis 400 and the bottom of the A-shaped frame 200 is higher than the top of the side plate 101 , which facilitates the work of lifting the crystalline silicon plate onto the side chassis 400 .

[0029] Furthermore, in order to improve the practicality of the plate transfer rack, a fixing mechanism 600 for fixing the plates is also provided in the present application. After the crystalline silicon plates are loaded and stacked on the side chassis 400, the fixing mechanism 600 can be used to quickly fix the crystalline silicon plates for subsequent transfer. Specifically, refer to Figures 1 to 2The fixing mechanism 600 includes a U-shaped locking frame 601 rotatably mounted on the top of the A-shaped frame 200. Preferably, the two ends of the opening of the U-shaped locking frame 601 are rotatably mounted on both sides of the top of the A-shaped frame 200, and are close to its top position. The outer end of the U-shaped locking frame 601 is provided with a buffer sleeve 602 for contacting the crystalline silicon panel. The buffer sleeve 602 is preferably made of rubber material, which can reduce the pressure damage to the crystalline silicon panel when fixing the crystalline silicon panel and maintain a close contact with the crystalline silicon panel. The inner end of the U-shaped locking frame 601 is provided with a locking component for limiting the rotation of the U-shaped locking frame 601, which is used to fix the U-shaped locking frame 601 after fixing the crystalline silicon panel to prevent the U-shaped locking frame 601 from loosening during the transportation of the crystalline silicon panel, causing the crystalline silicon panel to shake or tip over. By rotatably setting a U-shaped locking frame 601 on the top of the A-shaped frame 200, the buffer sleeve 602 on the U-shaped locking frame 601 can quickly fix the position of the crystalline silicon panels loaded on the side base frame 400, thereby improving the practicality of the device. In addition, the U-shaped locking frame 601 is connected to the A-shaped frame 200 in a rotatable relationship, that is, the U-shaped locking frame 601 can be rotated to any angle. Correspondingly, the distance between the buffer sleeve 602 on the U-shaped locking frame 601 and the side of the A-shaped frame 200 can be adjusted, that is, it can adapt to different batches of crystalline silicon panels and expand the range of use of the transfer rack. Furthermore, the locking assembly includes a mounting base 603 fixed to the top of the A-shaped frame 200 and a rotating shaft 604 passing through the mounting base 603. The mounting base 603 and the A-shaped frame 200 can be fixed by welding. The rotating shaft 604 passes through the A-shaped frame 200 and the mounting base 603. The open end of the U-shaped locking frame 601 is fixed to the end corresponding to the rotating shaft 604, that is, the U-shaped locking frame 601 can rotate around the rotating shaft 604 to adjust the distance between its buffer sleeve 602 and the side of the A-shaped frame 200. The top of the mounting base 603 is provided with a pair of limiting plates 605, which are arranged horizontally and have a plurality of limiting plates 605 on them. A locking rod 606 is inserted and provided, and the locking rod 606 moves up and down in the vertical direction. A positioning block 607 is provided on the locking rod 606 between the two limit plates 605. A return spring 608 is provided between the positioning block 607 and the top limit plate 605. Preferably, a pull block is fixed to the top of the locking rod 606 to facilitate pulling the locking rod 606 to move upward, and after releasing the pull block, the locking rod 606 automatically returns to its original position under the action of the return spring 608. A locking gear 609 is installed on the outer end of the rotating shaft 604, and a locking tooth row 610 is provided at the bottom end of the locking rod 606 to engage with the locking gear 609. When in use, by lifting the locking rod 606, the locking tooth row 610 moves up with the locking rod 606 and separates from the locking gear 609, that is, the restricted state of the U-shaped locking frame 601 is released. At this time, the two U-shaped locking frames 601 can be rotated upward synchronously to overlap together or rotated one after another. After the locking rod 606 is reset, the locking tooth row 610 and the locking tooth row 610 are engaged again to restrict the state of the U-shaped locking frame 601 again. After the U-shaped locking frame 601 is rotated, space is left above the side chassis 400 for stacking the crystalline silicon panels. After the crystalline silicon panels are loaded, the locking rod 606 is lifted again to rotate the U-shaped locking frame 601 downward and make the buffer sleeve 602 on it contact the outermost crystalline silicon panel (such as Figure 3 As shown in FIG), after the locking rod 606 is reset, the U-shaped locking frame 601 is fixed, thereby completing the purpose of fixing the crystalline silicon panels stacked on the side chassis 400, and the operation is quick and convenient.
