[0024] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0025] Example 1

[0026] Please refer to Figure 1-6As shown in the figure, a lifting protection tooling for a magnetic shielding plate includes a falling prevention guard plate 1; two of the falling prevention guard plates 1 form a group; a strap fixing hole 2 is opened at the top of the falling prevention guard plate 1; a tight strap 3 is connected between the strap fixing holes 2 of a group of the falling prevention guard plates 1; a bottom fixing component is provided at the bottom of the strap fixing hole 2; the falling prevention guard plate 1 is designed in a trapezoid shape; during work, when it is necessary to lift the magnetic shielding plate, the falling prevention guard plate 1 can be placed at the four corners of the bottom of the shielding plate, and then the strap fixing hole 2 can be fixed by the tight strap 3. At the same time, the bottom of the strap fixing hole 2 can be fixed by the bottom fixing component, so that the shielding plate can be fixed inside the falling prevention guard plate 1, and then the tight strap 3 can be hoisted, so that the shielding plate can be more stable during the hoisting process, effectively solving the problem that the shielding plate has a risk of falling during the hoisting process.

[0027] The bottom fixing component includes a wire reel 4, a fixing cable 5, a pulling block 8, and a first spring 10; the wire reel 4 is rotatably connected to the bottom position of one of the falling prevention guard plates 1; the fixing cable 5 is wound around the wire reel 4; a torsion spring is installed at the rotating shaft position of the wire reel 4; a wire groove 6 is opened at the bottom position of the falling prevention guard plate 1; a first sliding cavity 7 is opened at the bottom position of the other falling prevention guard plate 1; the pulling block 8 is slidably connected inside the first sliding cavity 7; a first spring 10 is fixedly connected between the pulling block 8 and the wire groove 6; a cable fixing hole 9 is opened on the pulling block 8; during work, when it is necessary to lift the shielding plate, the fixing cable 5 can be pulled out, and then the opposite cable fixing hole 9 can be pulled out. After hanging the fixing cable 5 inside the opposite cable fixing hole 9, the fixing cable 5 can be fixed inside the cable fixing hole 9 by the pulling force of the first spring 10, and the bottom of the shielding plate can be fixed by the fixing cable 5, so that the shielding plate is fixed more firmly and is more stable during the hoisting process.

[0028] A plurality of rubber cushion layers 11 are fixedly connected to the surface of the falling prevention guard plate 1; an adsorption groove 12 is opened on the side wall of the rubber cushion layer 11; the rubber cushion layer 11 is arranged at the inner position of the corresponding falling prevention guard plate 1; during work, when the shielding plate is fixed by the falling prevention guard plate 1, the rubber cushion layer 11 can increase the contact area between the falling prevention guard plate 1 and the shielding plate, so that the friction force between the shielding plate and the falling prevention guard plate 1 is increased, making the falling prevention guard plate 1 more stable when fixing the shielding plate. At the same time, when the shielding plate presses on the rubber cushion layer 11 at the bottom, the air inside the adsorption groove 12 can be squeezed out. By the principle of negative pressure, the rubber cushion layer 11 can be adsorbed on the surface of the shielding plate, so that the shielding plate is more firmly inside the falling prevention guard plate 1.

[0029] A second sliding cavity 13 is formed inside the anti-falling guard plate 1; an air extraction through-hole 14 is formed inside the rubber cushion layer 11; the second sliding cavity 13 is in communication with the air extraction through-hole 14; an air extraction plate 15 is slidably connected inside the second sliding cavity 13; a second spring 18 is fixedly connected between the air extraction plate 15 and the second sliding cavity 13; a connecting rod 16 is fixedly connected to the side wall of the air extraction plate 15; a contact block 17 is fixedly connected to the end of the connecting rod 16; during operation, when the shielding plate is fixed by the anti-falling guard plate 1, the contact block 17 can be pushed, so that the air extraction plate 15 pushes the second spring 18, expanding the space of the adsorption groove 12, thereby increasing the negative pressure inside the adsorption groove 12 and making the adsorption fixing ability stronger.

[0030] A plurality of positioning blocks 19 are fixedly connected to the side wall of the cable pulling block 8; a positioning groove 20 is formed inside the anti-falling guard plate 1; the positioning blocks 19 and the positioning groove 20 are arranged in correspondence; during operation, during the sliding process of the cable pulling block 8, through the mutual engagement of the positioning blocks 19 and the positioning groove 20, the cable pulling block 8 can be made more stable during the sliding process.

[0031] A plurality of anti-slip protrusions 21 are fixedly connected inside the cable fixing hole 9 and are arranged in a circumferential array pattern; during operation, when the fixed cable 5 is fixed inside the cable fixing hole 9, the anti-slip protrusions 21 can increase the contact area between the fixed cable 5 and the cable fixing hole 9, thereby increasing the friction between the fixed cable 5 and the cable fixing hole 9, so that the anti-slip protrusions 21 are more stable inside the cable fixing hole 9.

[0032] A pulling handle 22 is fixedly connected to the side wall of the cable pulling block 8; the pulling handle 22 is arranged at the position corresponding to the fixed cable 5; during operation, when it is necessary to hang the fixed cable 5, the pulling handle 22 can be pulled to pull out the cable pulling block 8. By setting the pulling handle 22, the pulling out of the cable pulling block 8 can be made more convenient.

[0033] An anti-friction ball 23 is snap-connected inside the positioning block 19; the side wall of the anti-friction ball 23 is in contact with the side wall of the positioning groove 20; during operation, when the cable pulling block 8 slides and the positioning block 19 comes into contact with the positioning groove 20, the anti-friction ball 23 can change the sliding friction between the positioning block 19 and the positioning groove 20 into rolling friction, reducing the friction between the positioning block 19 and the positioning groove 20, thereby reducing the wear between the positioning block 19 and the positioning groove 20.

[0034] Embodiment 2

[0035] Compared with Embodiment 1, as another implementation manner of the present invention, an anti-slip cushion layer is fixedly connected to the pulling handle 22; during operation, the anti-slip cushion layer can reduce the possibility of slipping when pulling the pulling handle 22, and at the same time reduce the feeling of pinching of the pulling handle 22.

[0036] Working principle: When it is necessary to lift the magnetic shielding plate during operation, the anti-drop guard plate 1 can be placed at the four corners of the bottom of the shielding plate. Then, the strap fixing holes 2 are fixed through the tightening straps 3. At the same time, the bottom of the strap fixing holes 2 can be fixed through the bottom fixing component, so that the shielding plate can be fixed inside the anti-drop guard plate 1. Then, the tightening straps 3 are hoisted, so that the shielding plate is more stable during the hoisting process, effectively solving the problem that the shielding plate has a risk of falling during the hoisting process.

[0037] When it is necessary to lift the shielding plate, the fixing cable 5 can be pulled out, and then the opposite cable fixing hole 9 is pulled out. After hanging the fixing cable 5 inside the opposite cable fixing hole 9, the fixing cable 5 can be fixed inside the cable fixing hole 9 by the pulling force of the first spring 10. The bottom of the shielding plate is fixed through the fixing cable 5, so that the shielding plate is fixed more firmly and more stable during the hoisting process.

[0038] When the shielding plate is fixed by the anti-drop guard plate 1, the rubber cushion layer 11 can increase the contact area between the anti-drop guard plate 1 and the shielding plate, thereby increasing the friction force between the shielding plate and the anti-drop guard plate 1, making the anti-drop guard plate 1 more stable when fixing the shielding plate. At the same time, when the shielding plate presses on the rubber cushion layer 11 at the bottom, the air inside the adsorption groove 12 can be squeezed out. Through the principle of negative pressure, etc., the rubber cushion layer 11 can be adsorbed on the surface of the shielding plate, so that the shielding plate is more firmly inside the anti-drop guard plate 1.

[0039] When the shielding plate is fixed by the anti-drop guard plate 1, the contact block 17 can be pushed, so that the air extraction plate 15 pushes the second spring 18, expanding the space of the adsorption groove 12, thereby increasing the negative pressure inside the adsorption groove 12 and making the adsorption and fixing ability stronger.

[0040] During the sliding process of the cable pulling block 8, through the mutual clamping of the positioning block 19 and the positioning groove 20, the cable pulling block 8 can be more stable during the sliding process.

[0041] When the fixing cable 5 is fixed inside the cable fixing hole 9, the anti-slip protrusions 21 can increase the contact area between the fixing cable 5 and the cable fixing hole 9, thereby increasing the friction force between the fixing cable 5 and the cable fixing hole 9, so that the anti-slip protrusions 21 are more stable inside the cable fixing hole 9.

[0042] When it is necessary to hang the fixing cable 5, the cable pulling block 8 can be pulled out by pulling the pulling handle 22. By setting the pulling handle 22, the pulling out of the cable pulling block 8 is made more convenient.

[0043] When the wire-pulling block 8 slides and the positioning block 19 contacts the positioning groove 20, the anti-wear ball 23 can change the sliding friction between the positioning block 19 and the positioning groove 20 into rolling friction, reducing the frictional force between the positioning block 19 and the positioning groove 20, thereby reducing the wear between the positioning block 19 and the positioning groove 20.
