Abstract

Chain detachment and chain entry are avoided, and a process for setting the length of a meshing chain is avoided, while the chain feed length can also be freely changed. A meshing chain stopper (190L) comprises a meshing chain stopper attachment part (191) and a contact-stop protrusion (192). The contact-stop protrusion (192) is contact-stopped at a contact-stop point (173A) provided on the periphery of a chain locus (L) when a pair of meshing chains (150, 150) are being driven.

Description

technical field [0001] The invention relates to an interlocking chain stopper for limiting the driving of an interlocking chain. Background technique [0002] In the prior art, there is known a type of actuator in which a driving sprocket coupled with an interlocking chain rotates, thereby driving a pair of interlocking chains to move forward and backward (for example, refer to Patent Document 1). [0003] exist Figure 13 In the above-described interlocking chain lifting device shown, a slipping out of the chain may occur, wherein the interlocking chain 250 slips out of the chain guide 272 after the end of the interlocking chain 250 passes the sprocket teeth of the drive sprocket 240 . Therefore, a control device is provided that outputs position information from a position sensor for detecting the position of the interlocking chain 250 to electrically or mechanically control the rotation speed of the chain driving motor. [0004] prior art literature [0005] patent doc...
