Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of coil steel, in particular to a coil steel sling applicable to a forklift. Background Art
[0002] A steel coil, also known as coil steel, is formed by hot pressing or cold pressing steel into a coil shape. For the convenience of storage, transportation and various processing, the formed coils are mainly hot-rolled coils and cold-rolled coils. A hot-rolled coil is a processed product before the recrystallization of a steel billet, and a cold-rolled coil is a subsequent processing of a hot-rolled coil.
[0003] The existing methods for loading and unloading coil steel are mainly divided into two types. One is to use large lifting equipment such as overhead cranes, truck cranes or gantry cranes for hoisting operations. The disadvantage of this method is that the equipment has poor flexibility, has high requirements for the operation site, and requires manual assistance in threading ropes beside, with high risks. The other method is to use a forklift for loading and unloading operations. The forklift uses fork blades to pass through the holes in the center of the steel coil, so as to realize the loading and unloading of the coil steel at a fixed position. The disadvantage of this method is that the sizes of the steel coils are different, and the holes in the middle of some steel coils are not large enough for the two fork blades of the forklift to pass through simultaneously. Lifting the steel coil only by a single fork blade will bring the risk of the steel coil falling due to insufficient support. When using this method to load the steel coil onto a vehicle, the hole of the steel coil is parallel to the cab of the transfer vehicle, and there is a catastrophic risk that the steel coil gets out of control and squeezes the cab due to sudden braking. Therefore, we propose a coil steel sling applicable to a forklift to solve the problems raised above. Content of the Utility Model
[0004] The purpose of the utility model is to solve the problems in the prior art that the sizes of the steel coils are different, the holes in the middle of some steel coils are not large enough for the two fork blades of the forklift to pass through simultaneously, lifting the steel coil only by a single fork blade will bring the risk of the steel coil falling due to insufficient support, and the hole of the steel coil is parallel to the cab of the transfer vehicle, and there is a catastrophic risk that the steel coil gets out of control and squeezes the cab due to sudden braking, and to propose a coil steel sling applicable to a forklift.
[0005] To achieve the above purpose, the utility model adopts the following technical scheme: A coil steel sling applicable to a forklift includes a sling body. A first fixing bolt through-hole is provided at the top position of the outer surface of the sling body, a second fixing bolt through-hole is provided at the bottom position of the outer surface of the sling body, a first snap ring through-hole is provided on the outer surface of the sling body, and a fork blade through-hole is provided on the inner surface of the sling body.
[0006] Preferably, a second snap ring through-hole is provided on the inner surface of the sling body.
[0007] Preferably, the depths of the first fixing bolt through-hole and the second fixing bolt through-hole are greater than the sling body.
[0008] Preferably, the first fixing bolt through-hole and the second fixing bolt through-hole are arranged in an equidistant manner, and there is more than one of the first fixing bolt through-hole and the second fixing bolt through-hole.
[0009] Preferably, the first clamp ring through-hole and the second clamp ring through-hole are connected in series with the other two clamp rings.

However, the present invention may also be implemented in other ways than those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.
[0023] Example 1, as Figures 1-7 As shown, a coil steel sling suitable for a forklift includes a sling body 6, a first fixing bolt through-hole 1 is provided at the top position of the outer surface of the sling body 6, a second fixing bolt through-hole 2 is provided at the bottom position of the outer surface of the sling body 6, a first retaining ring through-hole 3 is provided on the outer surface of the sling body 6, and a fork knife through-hole 4 is provided on the inner surface of the sling body 6.
[0024] The effect achieved by the entire embodiment 1 is that, in the subsequent actual use process, the sling body 6 is regarded as the supporting part of the steel coil, and the whole set is divided into two parts. On the two fork knives of the forklift, each fork knife is equipped with a pair. The main structure includes Figure 1 and Figure 3 part, Figure 1 and Figure 3 Partially relies on 3 clamps connected in series, Figure 1 Part is mainly connected and fixed with the fork and knife, Figure 3 Part is the main support structure of the coil, and Figure 1 As shown, Figure 1 The middle 4 parts are for fork and knife to pass through, and there are two fixing holes on each side. Figure 1 As shown in parts 1 and 2, there are threads in the fixing holes, which allow the fixing screws to pass through and press against the side of the fork knife, preventing the entire coil hanger from shifting on the fork knife and eliminating safety hazards caused by the hanger falling off.
[0025] Example 2, as Figures 1-7 As shown, a second snap ring through hole 5 is provided on the inner surface of the sling body 6, a second snap ring through hole 5 is provided on the inner surface of the sling body 6, the depth of the first fixing bolt through hole 1 and the second fixing bolt through hole 2 is greater than the sling body 6, the first fixing bolt through hole 1 and the second fixing bolt through hole 2 are arranged in an equidistant manner, there is more than one first fixing bolt through hole 1 and second fixing bolt through hole 2, the first snap ring through hole 3 and the second snap ring through hole 5 are connected in series with the other two snap rings.
[0026] The effect achieved by the entire embodiment 2 is as follows:Figure 1 As shown, its Figure 1 The middle 3 part is the first clasp hole 3, through which the clasp passes. Figure 1 The middle 3 parts are connected in series with the other two clasps, and the end clasp passes through Figure 3 Part 5 connects the two parts of the coil spreader into a whole. Figure 3 The middle 6 part passes through the central hole of the steel coil and provides the main support force for the lifting of the steel coil.
[0027] Working principle: During the whole process of use, when loading and unloading the steel coil, the two forks of the forklift are equipped with a pair of slings as shown in the figure. Figure 3 After the middle 6 parts penetrate the central hole of the steel coil, the forklift controls the fork knife to retract inwards and clamp the steel coil to prevent the sling from falling off after leaving the ground, causing a safety accident. After the fork knife is clamped, the forklift controls the fork knife to lift the steel coil off the ground, and then the forklift moves to the appropriate position and lowers the fork knife so that the steel coil is supported by the horizontal plane. After the fork knife disperses to both sides and leaves the steel coil, the fork knife is lifted and the forklift moves backward to complete the steel coil transfer operation. The cooperation of multiple people can provide a new operation mode for the lifting operation of steel coil, reducing the traditional use of overhead crane or tire The requirements for site and equipment during lifting operations have been reduced, and the cross-operation of manual assistance in securing slings during overhead crane and tire crane operations has been reduced. This has expanded the use of forklift equipment, reduced the company's equipment investment costs, and improved the inherent safety of the company's steel coil operations. In addition, the docking method of the steel coil has changed from parallel to the direction of the cab to perpendicular to the cab. Compared with sudden turns and brake activation, the brake activation operation is more frequent during vehicle reverse operation, which transfers the risk of steel coil rolling away from the cab and ensures the safety of the reverse vehicle driver. Therefore, the proposal of this utility model patent has greatly improved the convenience of steel coil loading and unloading operations and improved the safety of steel coil reverse operation.
