[0002] As a basic device for lifting heavy objects, slings are often used in multi-cargo warehouses and yards to improve work efficiency. In order to meet the daily maintenance and lifting needs of large machinery, some sling companies have also designed some special slings. However, the slings currently designed for the replacement of the winding side guides still have many safety hazards. When the winding operator replaces the side guide, he needs to stand on the roller table. The roller table is a spray-welded roller with a smooth surface. The operator cannot stand steadily when working on the roller table, which is prone to safety accidents and damage to equipment. During lifting, due to the special shape of the sling, there will be problems such as shaking and instability. In order to solve this kind of situation, a winding side guide replacement sling with safety and efficiency should be designed. Utility Model Content

[0023] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0024] The utility model provides Figure 1-5 The shown lifting device for replacing a winding side guide plate comprises a base 1 and a device lifting ear 2. The middle part of the base 1 is a convex structure. The two ends of the top of the convex structure of the base 1 are fixedly installed with the bottom of the device lifting ear 2. A plurality of window positions 3 for the side guide plate lifting ear structure to leak out are provided in the middle of the top of the convex structure of the base 1. Guarding mechanisms are fixedly connected on both sides of the base 1. Both sides of the top of the base 1 and between the opposite sides of the guarding mechanism are used for bearing and standing. A safety mechanism 5 is provided on the top of the guarding mechanism.

[0025] It should be noted that the material of the base 1 designed in this solution is steel plate to ensure strength and to support the installation work of the operator.

[0026] Specifically, the lock buckle 501 is sleeved on the top of the barrier mechanism;

[0027] A rope 502, one end of which is fixedly connected to the ring arm of the lock buckle 501;

[0028] A waist belt 503 , the outer surface of which is fixedly connected to an end of the rope 502 away from the buckle 501 .

[0029] It should be noted that the designed safety mechanism 5 refers to the safety belt structure of model AD8906, reduces the friction of the rope 502 connection, is thickened and wear-resistant and not easy to rust, and when the operator performs the installation operation, the lock buckle 501 is fastened to the nearest railing and the belt 503 is worn. If the organizer accidentally falls during the operation, the rope 502 of this design is connected to the belt 503 to hang the operator up. The rope 502 is made of all polyester, which has good strength and toughness and strong load-bearing effect, prevents falling, and allows the operator to replace the side guide more safely.

[0030] Specifically, the fixed protection device includes:

[0031] Fixed corners 101, multiple fixed corners 101 are fixedly installed horizontally and symmetrically on both sides of the top of the convex structure of the base 1;

[0032] The fixing ribs 102 are symmetrically fixed on both sides of the bottom of the convex structure of the base 1 along the horizontal transverse direction. The middle part of the enclosure plate 4 is provided with a plurality of gripping windows 401 arranged along the horizontal longitudinal direction. The top of the device lifting ear 2 is provided with a lifting hole for lifting.

[0033] It should be noted that the function of the side guide plate for coiling in the hot-rolled coil plant is as follows: the equipment is located on the entrance roller of the coiler and is used to guide and center the strip entering the pinch rollers, and guide the strip to enter the pinch rollers smoothly. When coiling, the side guide plates on both sides maintain appropriate side pressure to ensure that the strip does not deviate during coiling without damaging the strip, and to prevent the steel coil from forming a tower shape. During production, each piece of strip needs to be guided and aligned. The side guide plates rub against the strip for a long time and are severely worn. The side guide plates need to be replaced regularly. During operation, you need to stand on the roller surface and around the side guide plates.

[0034] Lift the device and transport it to the side guide plate position, let the side guide plate lifting ear leak out from the device window position 3, the operator stands in the guardrail mechanism, wears the safety mechanism 5, and uses the wire rope to hang the exposed lifting ear tightly. The lifting ear adopts a trapezoidal structure with good load-bearing capacity and stability, is not easy to deform, and has strong corrosion resistance. When using the lifting ear, first check the load mark of the lifting ear. It must be used according to the safe load and overloading is not allowed. Use the wire rope to lift the side guide plate lifting ear and the device lifting ear 2 at the same time; when installing, place the device on the side guide plate spare part, let the side guide plate lifting ear leak out, use the wire rope to hang it tightly and firmly, and lift the device and the side guide plate to the installation position at the same time. After it is in place, the operator stands on the platform to make adjustments. After the adjustment is completed, take out the wire rope at the side guide plate lifting ear and lift the device out. Replacing the side guide plate according to this device can effectively and safely replace the side guide plate, and at the same time it can also improve the working efficiency and ensure the equipment is in good condition.
