Problems solved by technology

[0002] The four-row chain tensioner is generally used to lift heavy objects, but the traditional four-row chain tensioner has a groove on the wire barrel, which allows the chain rope to be wound in the groove when it is recovered, but this greatly The length of the wire barrel is increased, thereby increasing the utilization of space, and when the chain rope is too long, it will be wrapped around one end of the wire barrel, and when it is wound too much, it may cause the chain rope to loosen

Abstract

The invention discloses an easy-to-use four-row chain tensioner. The easy-to-use four-row chain tensioner comprises two first partitions and a second partition arranged between the two first partitions. A fixed plate, a rope winding device arranged on the two first partitions, a refueling device arranged on the two first partitions, a door opening device arranged on the refueling device, a The lock case device can evenly roll back on the sleeve when the chain rope is retracted by the rope winding device, thereby avoiding that the chain rope is all wrapped around one end of the sleeve and cannot make effective use of the upper area of ​​the sleeve.

Description

technical field [0001] The invention belongs to the technical field of machinery, and in particular relates to a four-row chain tensioner which is convenient to use. Background technique [0002] The four-row chain tensioner is generally used to lift heavy objects, but the traditional four-row chain tensioner has a groove on the wire barrel, which allows the chain rope to be wound in the groove when it is recovered, but this greatly The length of the wire barrel is increased, thereby increasing the utilization of space, and when the chain rope is too long, it will be wrapped around one end of the wire barrel, and when it is too much, the chain rope may become loose. Contents of the invention [0003] In order to overcome the deficiencies of the prior art, the present invention provides a four-row ring chain tensioner that can reduce space utilization and avoid excessive winding at one end of the wire barrel. [0004] In order to achieve the above object, the present inven...
