Abstract
Description
Technical Field
[0001] This utility model relates to the field of metal sheet transfer technology, and in particular to a metal sheet transfer device. Background Technology
[0002] Metal sheets are sheets made from metal materials, such as aluminum and aluminum alloys, steel plates, stainless steel, and copper, through different processes.
[0003] Metal sheets require multiple processes during processing, and transfer devices are often used between different processes, such as automated conveyor belt transfer and transfer by handcart. These two transfer methods are very common in workshops.
[0004] When using a handcart to transport finished metal sheets, the finished metal sheets are often placed directly on the cart and then manually pushed to the designated location. However, most existing handcarts do not have a limiting device to restrict the movement of the sheets. As a result, if the sheets are not placed neatly during actual transport, the handcart will brake suddenly in case of an unexpected situation (such as when it is about to encounter other obstacles in the workshop). This may cause the metal sheets to slide or fall from the front of the cart, resulting in collisions between the metal sheets and the ground, causing damage to the sheets. Utility Model Content
[0005] The purpose of this utility model is to provide a metal sheet transfer device, which is equipped with a limiting device to limit the front and rear positions of the metal sheet, thereby effectively improving the protection of the metal sheet and preventing the sheet from falling from the front of the trolley.
[0006] The objective of this utility model is achieved through the following technical solution:

[0008] Preferably, each of the telescopic tubes consists of at least two interlocking movable tubes; adjacent movable tubes are slidably connected.
[0009] Preferably, on the two sides of adjacent moving tubes that are close to each other, one side is provided with a first slider, and the other side is provided with a vertical sliding groove that slides in cooperation with the first slider.
[0010] Preferably, the driving device driving the first connecting plate away from the direction of the push handle to move back and forth towards the direction of the push handle is further included.
[0011] Preferably, the driving device includes a plurality of second sliding blocks arranged at the bottom end of the first connecting plate, a plurality of horizontal sliding grooves arranged at the top end of the placing plate and slidingly matched with the second sliding blocks, a mounting plate arranged at the side of the placing plate away from the push handle, and a second hydraulic rod arranged at the top end of the mounting plate; the telescopic end of the second hydraulic rod is connected with the first connecting plate away from the push handle.
[0012] Preferably, the side of the placing plate and the mounting plate away from the push handle is provided with a first buffer layer.

Detailed Implementation
[0027] Example 1
[0028] A metal sheet transfer device, such as Figures 1-3 As shown, the device includes a placement plate 1, wheels (existing technology, not shown in the figure) at the bottom of the placement plate 1, and a push handle 2 on one side of the placement plate 1 (the push handle 2 is located at the rear of the transfer device in the direction of travel). The push handle 2 can be any existing technology capable of pushing. Two limiting devices are provided at the top of the placement plate 1, such as... Figure 2 As shown, the limiting devices are disposed at the front and rear edges of the placement plate 1. Each limiting device includes a first connecting plate 3 disposed at the top of the placement plate 1, a second connecting plate 4 disposed at the top of the first connecting plate 3, a row of telescopic tubes 5 disposed between the first connecting plate 3 and the second connecting plate 4, and at least one first hydraulic rod 6; as shown Figure 2 As shown, the first hydraulic rod 6 is disposed outside the two rows of telescopic tubes 5, as... Figure 3 As shown, each row of telescopic tubes 5 includes multiple telescopic tubes 5. Further, as... Figure 4 As shown, each of the telescopic tubes 5 consists of at least two interlocking movable tubes; adjacent movable tubes are slidably connected. Further, as... Figure 4 As shown, on the two sides of the adjacent moving tubes that are close to each other, one side is provided with a first slider 9, and the other side is provided with a vertical sliding groove 10 that slides and engages with the first slider 9.
[0029] Working principle: the metal plate to be transported is vertically stacked between the two first connecting plates 3, after the stacking is completed, the first hydraulic rod 6 is started to push the second connecting plate 4 to move upwards, and then the multiple telescopic pipes 5 are elongated to limit the front and rear positions of the metal plate between the two rows of telescopic pipes 5, effectively avoiding the technical defect that the metal plate falls from the front of the transport device when the emergency brake occurs, and causes the collision between the metal plate and the ground.
[0030] When the telescopic pipe 5 is elongated, the first sliding block 9 slides upwards in the vertical sliding groove 10, and then the multiple movable pipes achieve the purpose of relative sliding. The first sliding block 9 and the vertical sliding groove 10 can improve the telescopic smoothness of the telescopic pipe 5.
[0031] Embodiment 2
[0032] Because the position between the first connecting plate 3 and the second connecting plate 4 in embodiment 1 is difficult to adjust, it is difficult for the two rows of telescopic pipes 5 to be close to the front and rear sides of the metal plate, so in actual implementation, the two limiting devices can only prevent the metal plate from falling from the front side of the transport device, when the size of the metal plate is small, there may be a large distance between the metal plate and the two limiting devices, so when the emergency brake occurs, the metal plate may slide relatively between the two rows of telescopic pipes 5, and once the relative sliding occurs, it will also cause the wear between the metal plates.
[0033] Based on embodiment 1, as shown in Figures 5-7 , the transport device further includes a driving device for moving the first connecting plate 3 away from the direction of the push handle 2 (i.e. the front side of the metal plate) to and fro towards the direction of the push handle 2. Further, as shown in Figures 5-7 , the driving device includes multiple second sliding blocks 7 arranged at the bottom end of the first connecting plate 3, multiple horizontal sliding grooves 8 arranged at the top end of the placement plate 1 and slidingly matched with the second sliding blocks 7, a mounting plate 11 arranged on the side of the placement plate 1 away from the push handle 2, and a second hydraulic rod 12 arranged at the top end of the mounting plate 11; the telescopic end of the second hydraulic rod 12 is connected with the first connecting plate 3 away from the push handle 2. Further, the side of the placement plate 1 and the mounting plate 11 away from the push handle 2 is provided with a first buffer layer (prior art, not shown in the figure, such as a rubber layer, a silica gel layer) to reduce the impact when the transport device collides with the obstacle in front, and to avoid the wear of the side walls of the placement plate 1 and the mounting plate 11. Preferably, the top end of the placement plate 1 is provided with a second buffer layer (prior art, not shown in the figure, such as a rubber layer, a silica gel layer) to reduce the friction between the lowermost metal plate and the placement plate 1.
[0034] Working principle: when the metal plates are stacked, the metal plates are stacked as close as possible to the first connecting plate 3 behind the running direction, and when the stacking is completed, all the first hydraulic rods 6 are started, and then the second hydraulic rod 12 is started, so that the first connecting plate 3 connected with the second hydraulic rod 12 moves to the metal plate direction until the first connecting plate 3 contacts the metal plate. In this way, the distance between the metal plate and the limiting device can be greatly reduced, and the limiting ability of the limiting device to the metal plate can be improved.
[0035] Example 3
[0036] Based on example 2, as shown in Figure 5 and Figure 8 , the top end of the placing plate 1 is provided with a first binding belt 13 (selecting rubber belt, with slight elasticity) and a second binding belt 14 (selecting belt without elasticity), wherein, Figures 1-8 only Figure 5 and Figure 8 two binding belts are drawn, and the rest of the drawings are not drawn, as shown in Figure 5 and Figure 8 , a plurality of limiting holes 15 are arranged along the length direction of the first binding belt 13, and the free end of the second binding belt 14 is provided with a hook 16 matched with the limiting hole 15. The first binding belt 13 and the second binding belt 14 are both flat belts.
[0037] Working principle: when the metal plates are placed, first place the first binding belt 13 and the second binding belt 14 according to the placement position shown in Figure 3 , then place the metal plates, and then start the two limiting devices in the manner of example 2, then pass the first binding belt 13 over the top end of the metal plate, then stand at the position of the second binding belt 14 and pull the free end of the first binding belt 13, so that the hook 16 on the second binding belt 14 can be hung in the limiting hole 15 matched with it. At this time, the first binding belt 13 and the second binding belt 14 are in a straight state. By arranging two binding belts, the metal plates can be further limited, and under the action of the two binding belts and the two limiting devices, the four sides of the metal plates can be limited to prevent the metal plates from falling from any side, and the safety of the metal plates can be further improved.
