Description

TECHNICAL FIELD

[0001] The utility model belongs to carbon black production lifting technical field, concretely is chain type elevator for carbon black production. BACKGROUND

[0002] Carbon black is also called carbon black, which is an amorphous carbon, mainly obtained by incomplete combustion or thermal decomposition of hydrocarbon compounds under insufficient air conditions. Carbon black exists in the form of aggregates and is usually used as a reinforcing agent and filler for rubber. The consumption of carbon black is about half of the consumption of rubber. The finished carbon black product needs to be transported to the packaging or storage area. At this time, the chain elevator is usually used to transport the carbon black product.

[0003] The utility model patent with patent application publication number 202323127380.9 discloses a chain type elevator structure, which includes a stand, a lifting mechanism, and a fork. The fork moves vertically along the stand and is lifted under the drive of the lifting mechanism. When the fork needs to be lifted, the drive mechanism is reversed. Because the driving force is greater than the weight of the slider, the fork, and the load on it, the fork is lifted with the counterclockwise movement of the chain. When the fork needs to be lowered, the drive mechanism is turned clockwise, and the fork is lowered with the clockwise movement of the chain. At the same time, under the action of the weight of the slider, the fork, and the load on it, the chain remains straight, thereby realizing the lifting function of the chain type elevator structure, facilitating the processing and installation of the equipment, and having strong applicability. The chain has high strength and can meet the lifting needs of heavy loads. At the same time, the chain can be easily spliced, lengthened, or disassembled and shortened, which is convenient for expanding equipment of various heights, especially for super-high equipment, which is convenient to expand and has great advantages.

[0004] However, the above-mentioned device still has disadvantages in actual use. The most obvious one is that when the chain load is too large and causes rupture, the lifting seat and the supporting frame lose support and fall. Because the buffering capacity of the supporting frame is weak, the supporting frame directly receives the impact force, causing damage to the materials and equipment, and reducing the use safety of the elevator. Therefore, we propose a chain type elevator for carbon black production. Utility model content

[0020] In the scheme of this application:

[0021] 1. When the chain is overloaded and breaks, the lifting seat and the support frame lose support and fall. At this time, the support frame drives the buffer plate to move downward, so that the buffer plate contacts the ground first. At this time, the buffer plate is buffered by the connecting piece, and drives the movable block and the second U-shaped block to move longitudinally. The second U-shaped block drives the transmission rod to rotate in the first U-shaped block through the rotating shaft. Due to the reduction in the distance between the support frame and the buffer plate, the transmission rod can push the two groups of movable blocks to slide relative to each other on the sliding rod, and apply reverse force to the two groups of movable blocks through the second spring, thereby buffering the movement of the buffer plate, reducing the impact force on the support frame, reducing the damage to materials and equipment, and improving the safety of the hoist.

[0022] 2. A motor is set to drive the worm to rotate, and the worm drives the worm wheel and the rotating shaft to rotate, and the rotating shaft drives the sprocket to rotate. The chain is stored by the rotation of the sprocket, and the chain drives the lifting seat to rise and fall. When the motor is suddenly powered off, the worm can drive the worm wheel to rotate, but the worm wheel cannot drive the worm to rotate. This prevents the lifting seat from pulling the sprocket in the opposite direction through the chain, thereby improving the use efficiency of the lifting seat. BRIEF DESCRIPTION OF THE DRAWINGS
