As shown in fig. 1 to 9, the application provides a chain length measuring device, which comprises a base 1 and measuring holes 2 arranged on the base 1, wherein guide rolling mechanisms 3 for guiding an anchor chain to pass through the measuring holes 2 in the vertical direction are arranged on two sides of the base 1, a transverse correcting mechanism 4 is arranged on each guide rolling mechanism 3, a measuring seat 5 is arranged in each measuring hole 2, two measuring through grooves 6 which are communicated with each other vertically are formed in each measuring seat 5, and an elastic measuring mechanism 7 for rolling contact with the anchor chain is arranged on the inner side wall of each measuring through groove 6.
The transverse correction mechanism 4 is located between the measuring hole 2 and the guiding rolling mechanism 3, and is used for sweeping the chain links on the anchor chain to the adjacent chain links in the horizontal direction, the two adjacent chain links on the anchor chain vertically pass through the two measuring through grooves 6 in the mutually vertical postures, the elastic measuring mechanism 7 is elastically compressed and counted in the horizontal direction when being in contact with the chain links, and the deformation is recovered when the chain links are separated.

When the anchor chain is released or rolled up by the windlass, the guide rolling mechanism 3 restricts the movement of the anchor chain in the vertical direction while in rolling contact with the anchor chain, so as to enter the lateral correction mechanism 4 along a predetermined path.
When the anchor chain passes through the transverse correction mechanism 4, the transverse correction mechanism 4 sweeps chain rings on the anchor chain along the horizontal direction, so that two adjacent chain rings on the anchor chain are mutually perpendicular, and can normally enter two measuring through grooves 6 in the measuring hole 2 and then contact with the elastic measuring mechanism 7.
When the elastic measuring mechanism 7 contacts the chain ring of the anchor chain, two adjacent chain rings on the anchor chain enter the two measuring through grooves 6 respectively, namely, the elastic measuring mechanism 7 can intermittently contact the chain ring of one chain ring at intervals on the anchor chain, so that after the elastic measuring mechanism 7 contacts the chain ring of the anchor chain, the elastic measuring mechanism 7 moves to the tail end along the head end of the chain ring, then the elastic measuring mechanism 7 is separated from the chain ring and contacts the chain ring in the same direction after a period of time is separated, the elastic measuring mechanism 7 is elastically deformed when contacting the chain ring, and is deformed when being separated from the chain ring, the releasing or rolling length of the anchor chain can be obtained by recording the deformation times of the elastic measuring mechanism 7 and combining the length of the chain ring, the control of the anchor chain is more accurate, and the problem that in the prior art, when the rotation number of the chain ring on the anchor jack is recorded, errors are larger due to thicker anchor chain and inconsistent length of each ring is avoided.
