[0026] It should be noted that unless otherwise specified, the technical terms or scientific terms used in this application should have the ordinary meaning understood by those skilled in the art to which the present invention belongs.

[0027] See Figures 2 to 6 , a steel plate stacking material 1 lifting and protecting device for a steel plate transverse cutting and shearing line in this application includes a main body frame 5. The main body frame 5 is a rectangular frame structure. Connecting members 52 for connecting with the lifting rod 2 are respectively provided on the left and right sides thereof. A front limiting portion 53 and a rear limiting portion 54 extending upward are respectively provided on the front and rear sides thereof. A top limiting portion 55 is connected between the upper ends of the front limiting portion 53 and the rear limiting portion 54. Below the top limiting portion 55, a receiving space for receiving the stacking material 1 is formed by enclosing the front limiting portion 53, the top limiting portion 55, and the rear limiting portion 54.

[0028] During use, place the main body frame 5 of the protecting device in this application on the stacking material 1, such that the left and right sides of the main body frame 5 are located above the two ends of the lifting rod 2, and the stacking material 1 is located within the receiving space of the main body frame 5. Then, connect and fix the connecting members 52 on the left and right sides of the main body frame 5 with the lower lifting rod 2. During lifting, hang the sling 3 fixed on the lifting rod 2 on a crane, and lift the stacking material 1, the lifting rod 2, and the protecting device in this application to a pallet together by the crane.

[0029] In this application, a front limiting part 53 and a rear limiting part 54 extending upward are respectively arranged on the front and rear sides of the main body frame 5. The upper ends of the front limiting part 53 and the rear limiting part 54 are connected by a top limiting part 55. When the stacked material 1 is lifted, the left and right sides of the stacked material 1 are respectively limited by the sling 3, the front and rear sides are respectively limited by the corresponding front limiting part 53 and rear limiting part 54, and the top is limited by the top limiting part 55, realizing the protection of the stacked material 1 in five directions, effectively preventing the sliding accident of the stacked material 1, and ensuring the safety of relevant operators and the continuous operation of production.

[0030] Specifically, the main body frame 5 is formed by connecting square steels of 60×40×4mm, with a length of 2600mm, a width of 2040mm, and a height of 400mm; the front limiting part 53 and the top limiting part 55 are a single square steel, and the rear limiting part 54 is two square steels. The upper end of the rear limiting part 54 is bent towards the front limiting part 53 to form a bent part. One end of the top limiting part 55 is connected to the end of the bent part, and the other end is connected to the upper end of the front limiting part 53.

[0031] A plurality of connection holes 51 are arranged at intervals on both the left and right sides of the main body frame 5, and the connecting piece 52 is inserted into the connection holes 51.

[0032] In this embodiment, 12 pin holes are respectively arranged at intervals on the left and right sides of the main body frame 5, and the diameter of each pin hole is 38mm, which is used to fix the load-bearing hanging rod 2 when lifting stacked materials 1 of different specifications; the connecting piece 52 is a pin, which is composed of a pin rod with a diameter of 36mm and a top cap with a diameter of 50mm. The top cap is fixed on the pin rod, and the total height of the pin is 120mm.

[0033] In order to adapt to stacked materials 1 of different specifications, a baffle assembly 6 is further included. The baffle assembly 6 is installed on the front limiting part 53 and can move towards or away from the rear limiting part 54. When in use, by adjusting the baffle assembly 6, the front and rear sides of the stacked material 1 are clamped between the baffle assembly 6 and the rear limiting part 54.

[0034] Specifically, the baffle assembly 6 includes a steel plate baffle 61, an adjusting screw rod 62, and an adjusting handwheel 63. The adjusting screw rod 62 is threadedly connected to the front limiting part 53. One end facing the rear limiting part 54 is fixedly connected to one side of the steel plate baffle 61, and the end far from the rear limiting part 54 is connected to the adjusting handwheel 63. By rotating the adjusting handwheel 63, the adjusting screw rod 62 is driven to rotate, and thus the steel plate baffle 61 is driven to move under the action of the thread pair, realizing the clamping of the stacked material 1.

[0035] The length of the adjusting screw rod 62 is 400 mm and the diameter is 20 mm. A screw nut sleeve is sleeved on the adjusting screw rod 62. The screw nut sleeve passes through the front limiting part 53 and is fixedly connected with the front limiting part 53, so as to realize the threaded connection between the adjusting screw rod 62 and the front limiting part 53. The steel plate baffle 61 is a rectangular plate structure with dimensions of 300×50×4 mm. One side of the steel plate baffle 61 is fixed to the adjusting screw rod 62, and the other side is attached to the front side of the stacked material 1 during use. The outer diameter of the adjusting handwheel 63 is 120 mm, and a handle is eccentrically installed thereon. By rotating the handle on the adjusting handwheel 63, the adjusting screw rod 62 is driven to rotate, thereby driving the steel plate baffle 61 to move.

[0036] In order to facilitate the hoisting of the main body frame 5, a lifting lug 4 is further included, and the lifting lug 4 is installed at the four corners of the main body frame 5.

[0037] Specifically, there are four lifting lugs 4, which are respectively installed at both ends of the left and right sides of the main body frame 5. The lifting lugs 4 are made of steel and are of a rectangular frame structure with one side open, facilitating the entry of the lifting rope. The openings of the four lifting lugs 4 are arranged in pairs back to back. Its bottom is fixed to the main body frame 5, and the end of the top extends towards the bottom direction to form a bent limiting stop part; the overall length is 100 mm, the width is 12 mm, the height is 60 mm, and the thickness of the steel is 5 mm.

[0038] During hoisting, after the 0.7*1420*2425 mm steel plate stack is collected, the stacked material 1 needs to be hoisted from the receiving table to the tray for bundling. The stacked material 1 is 2425 mm long, 1420 mm wide, and 280 mm high (400 sheets per pack). Four load-bearing lifting rods 2 are evenly placed below the stacked material 1 (as Figure 1 shown). The four lifting lugs 4 at the four corners of the device of the present application are hung on the four-way lifting tool of the crane through the sling 3. The crane hoists the device of the present application to the stacked material 1, so that the stacked material 1 is located in the accommodating space, and the left and right sides of the main body frame 5 are located above the lifting rods 2. The lifting rods 2 are connected to the two ends of the lifting rods 2 through the pins arranged on the left and right sides of the main body frame 5. The slings 3 at the two ends of the lifting rods 2 are hung on the crane, and the crane slightly lifts the lifting rods 2. At this time, the protection device of the present application is lifted together with the lifting rods 2. Then, manually rotate the handwheel 63 to make the steel plate baffle 61 abut against the front side of the stacked material 1, and cooperate with the rear limiting part 54 to play the role of front and rear stops. After adjustment, the whole is hoisted to the tray by the crane; by using the protection device of the present application, during the whole hoisting process, the stacked material 1 and the lifting rods 2 are both very stable.
