Problems solved by technology

[0007] But, there is following problem in above-mentioned hoisting device: as Figure 8 As shown, when the pair of engaging chains 211, 211 are engaged with each other and rise, the horizontal component force F of the load is generated, which makes the pair of engaging chains 211, 211 tilt, thus causing the vertical pair of engaging chains 211, 211 to independently move along the vertical direction. It becomes very difficult to transport the driven body 220 to a higher position within a certain chain length range, and a gap is generated between the meshing chain plates 213, which reduces the meshing accuracy, and at the same time, the load acting on the chain plates 213 is not affected. uniform, making it difficult to increase the buckling strength of the pair of meshing chains 211, 211
[0008] In addition, once a load is continuously applied to the inclined pair of meshing chains 211, 211 from above to below in the vertical direction, and the horizontal component force F of the load is increased, the pair of meshing chains 211 will be further enlarged. , 211, the buckling strength is further reduced. Therefore, when assembling a device provided with a reinforcing member that reinforces a pair of meshing chains 211, 211, while increasing the workload, the number of parts of the device is increased, and in order to ensure the specified buckling strength, it is necessary to increase the size of the meshing chain 211, that is, the cross-sectional area of ​​a pair of meshing chains 211, 211 that are meshed together

Abstract

There is provided a lifting engagement chain unit that autonomously erects a pair of engagement chains, ensures engagement accuracy between link plates and improves buckling strength. A plurality of buckling restricting attachment plates is arrayed along an outer surface of the engagement chains in a chain longitudinal direction.

Description

technical field [0001] The present invention relates to a driving device that is used in manufacturing equipment in various manufacturing fields, transfer equipment in the transportation field, nursing equipment in the medical and welfare field, stage equipment in the art field, etc., to raise and lower the driven object relative to the installation surface The lifting drive uses an intermeshing chain unit. Background technique [0002] Conventionally, there is an elevating device that rotates a drive sprocket engaged with an intermeshing chain to elevate a pair of intermeshing chains (for example, refer to Patent Document 1). [0003] like Figure 8 As shown, in a state where the flat plate end surfaces 213S facing the opposite sides of the plate engaging surfaces of the chain plates 213 contact each other obliquely with respect to the lifting direction, the engaging chains used in the above-mentioned lifting device are driven up and down, thereby driving up and down. The ...
