Description

TECHNICAL FIELD

[0001] The utility model relates to hoisting equipment field for tire production, in detail is a kind of four-jaw balancing device for auxiliary hoisting of carbon black / white carbon black ton bag in tire production process. BACKGROUND

[0002] It is known that in tire manufacturing industry, carbon black / white carbon black is an important auxiliary agent in rubber production, and the dosage is relatively large. Most of the carbon black from the manufacturer is in the form of ton bag, and the tire production enterprise needs to use artificial unpacking to pour the finished carbon black into the carbon black conveying device, and then complete the process of adding carbon black to natural rubber.

[0003] The usual operation mode of artificial carbon black unpacking is to use hoisting tools to lift the carbon black / white carbon black ton bag above the unpacking device, open the discharge port below the ton bag manually, and then the carbon black / white carbon black enters the unpacking station through the discharge port below the ton bag by its own weight, and then the whole process of conveying carbon black / white carbon black to tire production equipment is completed. Because carbon black / white carbon black has the characteristics of small particle size and light weight, each ton bag has a large volume. If the ton bag is directly hoisted by the hook of the hoisting tool, there are problems of inclination, unstable ton bag gravity center and unbalanced ton bag hoisting, which has serious safety hazards. SUMMARY

[0004] In order to overcome the shortcomings of the prior art, the utility model provides a four-jaw balancing device for auxiliary hoisting, which solves the problems of unstable ton bag gravity center after lifting and unbalanced ton bag hoisting during the current carbon black / white carbon black ton bag hoisting process.

[0005] The technical scheme adopted by the utility model to solve its technical problems is: a four-jaw balancing device for auxiliary hoisting, provided with a balance support plate, characterized in that two balance support plates are connected in a cross shape, the connection point is located at the center of the balance support plate, the end of the balance support plate is processed with a hook claw, the hook claw extends upward, the adjacent balance support plates are connected with reinforcing ribs, and a lifting ring is installed at the middle position of the balance support plate.

[0006] The utility model has the beneficial effects that the ton bag runs smoothly in the air without abnormal shaking and imbalance. BRIEF DESCRIPTION OF DRAWINGS

[0007] The utility model will be further described below in combination with the drawings and examples.

[0008] Figure 1 The utility model is a structural schematic diagram.

[0009] In the figure, 1 is a lifting ring, 2 is a hook claw, 3 is a balance support plate, and 4 is a reinforcing rib. DETAILED DESCRIPTION

[0010] In the figure, the utility model is equipped with balance support plate 3, two balance support plates 3 adopt cross form connection, and the connecting point is located in the center of balance support plate 3, two balance support plates 3 are fixed perpendicularly intersecting each other, the distance from the intersection fixed point to the end of balance support plate 3 is equal, the end of balance support plate 3 is processed with lifting hook claw 2, lifting hook claw 2 extends upwards, ensures that carbon black / white carbon black ton bag four corners lifting ring cannot fall off from lifting hook claw 2, reinforcing rib 4 is connected between adjacent balance support plate 3, four reinforcing ribs 4 are welded and fixed at the intersection point of every two balance support plates 3, increase the strength of the whole balance device, and there is lifting ring 1 above the intersection fixed point in the middle of two balance support plates 2, the lifting ring 1 is located at the center point of four-jaw balance device, the hook of auxiliary hoisting device is connected with lifting ring 1, in the process of hoisting and lifting and unpacking carbon black / white carbon black ton bag, lifting ring 1 can ensure that the hoisting point and the center of gravity of ton bag coincide.

[0011] The utility model four-jaw balance device is used for hoisting carbon black / white carbon black ton bag, and four lifting hook claws on balance support plate firmly fix the lifting ring on the top of ton bag, the lifting hook claws extend upwards, can avoid that the lifting ring falls off from the lifting claw. Utilize the lifting ring above the middle of balance device, hoist through the hook of hoisting device and be connected, and the four corners of ton bag are evenly stressed in the hoisting process, and the lifting point of hoisting device and the center of gravity of ton bag are in the same center line, ensure that ton bag runs stably in the air, and there is no abnormal swing, imbalance and the like, eliminate the security risk existing in the unpacking process.

Claims

1.
