Description

Technical Field

[0001] This utility model belongs to the field of hoisting equipment technology, and in particular relates to a plate lifting tool. Background Technology

[0002] The materials used to make electrical control cabinet bodies are mostly thinner plates. During processing, the rolled plates are first cut into sections, and then hoisted onto a laser cutting machine. The laser cutting machine cuts the plates according to the drawings.

[0003] Because the sheet material is thin, special lifting equipment is required for hoisting. For example, a flat plate is set up, with the top surface of the plate connected to the output end of the hoisting equipment. Multiple electromagnetic chucks are set on the bottom surface of the plate to attract and transfer the sheet material. However, this method is susceptible to voltage abnormalities or external interference, which may lead to the risk of the sheet material falling.

[0004] To address the issue of material falling, Chinese Utility Model Patent Application No. 202420372308.8, entitled "Sheet Material Lifting Tool," has made improvements. Specifically, this lifting tool discloses a hook and a rod rotatably connected to the hook. The outer end of the hook has a hook portion, forming a holding space between the hook portion and the rod. This holding space gradually increases from the outside in. The inner end of the hook has a pivot. The upper end of the rod has a connecting portion located above the hook. The lower end of the rod has a connecting hole that rotatably engages with the pivot and extends downward into the holding space to form a supporting portion. This supporting portion is located relative to the top surface of the hook portion near the hook portion. Utilizing the gradually increasing holding space, during unloading, the rod rotates outward, cooperating with the supporting portion to rotate inward to separate from the sheet material, and the hook moves outward, thus separating the sheet material from the hook. This not only prevents the sheet material from falling during lifting but also allows the hook to be easily removed during unloading, preventing the sheet material from getting stuck, ensuring smooth unloading, and improving work efficiency.

[0005] However, because the sheet material is relatively thin, when the lifting equipment is used to lift it, the curved surface at the lower end of the support part forms a line contact with the top surface of the sheet material, which can easily damage the sheet material, resulting in more waste and thus higher costs. Utility Model Content

[0006] To address the shortcomings of the existing technology, this utility model provides a sheet metal lifting device that not only prevents the sheet metal from falling during lifting and rotating, but also prevents the sheet metal from being crushed, thereby improving the utilization rate of the sheet metal and reducing costs.

[0007] In order to achieve the purpose of this utility model, the following solution is proposed: A sheet metal lifting device includes a lifting device connector, which includes a lifting base. The bottom of the lifting base is provided with a suction cup, and lifting members are provided on both sides of the lifting base for telescopic movement. Each lifting member includes a side frame, and L-shaped support plates are arranged in a row at the bottom of the support plate. The inner right angle of the support plate faces the lifting base, and rollers are provided on the top surface of the horizontal part of the support plate.

[0008] Furthermore, the hanging base has an inverted U-shaped structure, with a lifting ring at the top and a base plate at the bottom. A set of telescopic rods are vertically arranged at intervals at both ends along the long axis of the base plate, and suction cups are located at the lower ends of the telescopic rods.

[0009] Furthermore, a bidirectional cylinder is arranged along the short axis of the base plate, and the hanger straddles the bidirectional cylinder. The output end of the bidirectional cylinder is arranged horizontally along the long axis of the base plate, and the output end of the bidirectional cylinder is connected to the middle of the side frame respectively.

[0010] Furthermore, the outer end of the horizontal part of the pallet is provided with an inclined surface, and the top surface of the horizontal part of the pallet is provided with a groove. One end of the groove is connected to the inclined surface, and the roller is located in the groove, with the roller protruding from the horizontal part of the pallet at a certain height.

[0011] Furthermore, the vertical part of the pallet has a cylindrical structure, and its outer wall is fitted with a shock-absorbing sleeve.

[0012] The beneficial effects of this utility model are as follows: During the lifting and rotating of the sheet metal, not only can the sheet metal be prevented from falling, but the clamping force acting on the sheet metal can also be prevented from being concentrated in a certain place on the sheet metal, which would cause damage to the clamping position of the sheet metal, thereby improving the utilization rate of the sheet metal and saving costs.

[0020] To make the objectives, technical solutions and advantages of the present utility model clearer, the implementation methods of the present utility model will be described in detail below with reference to the accompanying drawings. However, the embodiments described in the present utility model are only some embodiments of the present utility model, and not all embodiments.

[0021] like Figures 1-5 As shown, this embodiment provides a sheet metal lifting tool, a lifting tool connector 10, and lifting members 20 symmetrically arranged on both sides of the lifting tool connector 10.

[0022] Specifically, such as Figure 1 , Figure 4 As shown, the lifting device connector 10 includes a lifting base 11, a suction cup 12, and a two-way cylinder 13. The lifting base 11 has an inverted U-shaped structure, with a lifting ring at the upper end for connecting to the output end of the lifting equipment, and a base plate 111 at the lower end. The base plate 111 has a rectangular plate structure, with a telescopic rod 112 extending vertically downward from the output end at its bottom. A set of the telescopic rod 112 is provided at both ends along the long axis of the base plate 111. The suction cup 12 is correspondingly located at the lower end of the telescopic rod 112 and is used to adsorb the plate 1 when gripping it.

[0023] The bidirectional cylinder 13 is located on the top surface of the base plate 111. The cylinder body of the bidirectional cylinder 13 is positioned relative to the short axis of the base plate 111, and the axis of the output end of the bidirectional cylinder 13 is perpendicular to the axis of the long axis of the base plate 111. The output ends of the bidirectional cylinder 13 are connected to the lifting member 20 respectively.

[0024] like Figures 1-2 As shown, the lifting component 20 includes a side frame 21 and a support plate 22. The side frame 21 is located outside the base plate 111, and the length direction of the side frame 21 is parallel to the long axis direction of the base plate 111. The middle part of the side frame 21 facing the base plate 111 is connected to the output end corresponding to the bidirectional cylinder 13. The support plate 22 has an L-shaped structure, and the support plates 22 are arranged in an array along the length direction of the side frame 21. The upper end of the vertical part of the support plate 22 is connected to the lower end of the side frame 21. The inner right angle of the support plate 22 faces the base plate 111. When the plate 1 is lifted by the suction cup 12, the horizontal part of the support plate 22 is used to support both sides of the plate 1.

[0025] To avoid wear between the top surface of plate 1 and support plate 22, such as Figure 3 As shown, a groove 222 is recessed on the top surface of the horizontal part of the pallet 22, and a roller 221 is arranged in the groove 222. The axis of the roller 221 is perpendicular to the length direction of the horizontal part of the pallet 22.

[0026] To facilitate material unloading, the plate 1 is separated from the horizontal part of the pallet 22. An inclined surface is provided on the top surface of the horizontal part of the pallet 22 at the end away from the vertical part of the pallet 22. One end of the groove 222 extends downward along the inclined direction of the inclined surface, and rollers 221 are arranged in a section of the groove 222 corresponding to the inclined surface, with the outermost roller 221 protruding from the end of the horizontal part of the pallet 22 away from the vertical part of the pallet 22.

[0027] Meanwhile, to prevent the vertical part of the pallet 22 from colliding with the sides of the plate 1 when the pallet 22 moves closer to the sides of the plate 1, thus damaging the sides of the plate 1, the vertical part of the pallet 22 is set into a cylindrical structure and a protective sleeve is fitted on its outside. The protective sleeve can be made of sponge, soft rubber or cloth strips, etc.

[0028] Specific operating procedures: Connect the hook to the output end of the lifting equipment, start the gantry crane, and move the lifting equipment to directly above the stacked plates 1. Lower the steel cable. When the suction cup 12 reaches a certain height, activate the telescopic rod 112, making it vertically downwards until the suction cup 12 picks up the plates 1 and stops. After the suction cup 12 picks up the plates 1, the telescopic rod 112 retracts vertically upwards. At this point, when the bottom surface of the plates 1 is higher than the top surface of the horizontal section of the support plate 22, activate the double-acting cylinder 13, causing it to move the side frames 21 on both sides closer to the sides of the plates 1. Figure 5 As shown, the rollers 221 on the horizontal part of the pallet 22 lift the bottom surfaces of both sides of the plate 1, preventing the plate 1 from falling during the lifting process, and also preventing the horizontal part of the pallet 22 from rubbing against the bottom surface of the plate 1 and scratching it.

[0029] After the sheet material 1 is hoisted to the cutting area of ​​the laser cutting machine, the hoisting equipment lowers the lifting device vertically downwards to a certain height in the cutting area. Then, the bidirectional cylinder 13 is activated, which pushes the side frame 21 to move away from the base plate 111, so that the horizontal part of the support plate 22 moves out of the bottom surfaces on both sides of the sheet material 1. When the horizontal part of the support plate 22 moves out to the sides and transitions to the position where the horizontal part of the support plate 22 is inclined, the telescopic rod 112 is activated vertically downwards. The two sides of the sheet material 1 move downwards along the inclined surface. As the telescopic rod 112 pushes the suction cup 12 downwards, the inclined surface of the horizontal part of the support plate 22 gradually separates from the two sides of the sheet material 1, so that the sheet material 1 can be placed stably in the cutting area, avoiding damage to the sheet material 1, improving the utilization rate of the sheet material, and thus saving costs.

[0030] The above description is merely a preferred embodiment of this utility model and does not imply its uniqueness or limitation. Those skilled in the art should understand that various changes or equivalent substitutions made to this utility model without departing from its scope are all within the protection scope of this utility model.
