Chain cycle load device

Abstract

The invention discloses a chain circulation bearing device which comprises two columns of circulation chains which are parallel and run in the same direction. The two columns of circulation chains are arranged on a chain wheel group. A plurality of freight houses are hung between the two columns of circulation chains at equal intervals. The chain circulation bearing device is characterized in that the bearing device also comprises two closed rod chain rings in one-to-one correspondence use with the two columns of circulation chains. Each rod chain ring comprises a plurality of connection rods; one end of each connection rod is a chain hinge end, and the other end is a mutual hinge end; the chain hinge ends of the adjacent two connection rods are hinged to the corresponding circulation chain through a chain hinge shaft; the mutual hinge ends of the adjacent two connection rods are hinged through a mutual hinge shaft; and the freight houses are hung on the rod chain rings at equal intervals. According to the chain circulation bearing device, cases of extension of the circulation chains are reduced under the condition of ensuring smooth operation, thereby improving reliability of the circulation chains and prolonging the service life of the chain.

Description

technical field [0001] The invention relates to a cargo handling and storage technology, in particular to a chain circulation loading device. Background technique [0002] Almost all kinds of circulating load devices used in many industrial processes use chains to transmit motion and power, of which sleeve roller chains are the most commonly used. The use of a small pitch chain can make the motion stable, but the dynamic load is insufficient, while the use of a large pitch chain can ensure the dynamic load, but the motion stability is poor. Cyclic loading devices often have to operate under unfavorable working conditions such as heavy cargo eccentric load, fast circulation, frequent start and stop, forward and reverse rotation, and open oil-free. Chains, unstable motion and insufficient dynamic load will lead to chain link wear and elongation, as well as chain plate fatigue, chain hinge gluing, etc., which may eventually lead to chain failure, and elongation is the main for...

Problems solved by technology

The use of small pitch chains can make the movement stable, but the dynamic load is insufficient, while the use of large pitch chains can ensure the dynamic load, but the movement stability is poor

Cyclic loading devices often have to operate under unfavorable working conditions such as heavy cargo eccentric load, fast circulation, frequent start and stop, forward and reverse rotation, and open oil-free. Chains, unstable movement and insufficient dynamic load will lead to chain link wear and elongation, and also include chain plate fatigue, chain hinge gluing, etc., which may eventually lead to chain failure, and elongation is the main form of chain failure

For various cyclic loading devices, if the failed chain is not replaced, the entire device must be discarded, and if it is replaced, it means that the device must be completely dismantled, and the manpower, material resources, financial resources and time consumed can be imagined

Not only that, the chain may break suddenly during operation and cause serious accidents

Various efforts have been made in many existing technologies, including strengthening the chain plate, anti-wear and anti-friction of the chain hinge, and enhanced lubrication, etc., but it is difficult to balance the dilemma of stable movement and guaranteed load bearing
