Passive double freedom deviation correcting device
Technical field
The present invention relates to a kind of load-transfer device deviation correcting device for belt conveyer, say more specifically a kind of passive double freedom deviation correcting device for belt conveyer.
Background technology
Belt conveyer is a kind of friction-driven machinery of transported material in a continuous manner, mainly formed by frame, load-transfer device, carrying roller, cylinder, tightening device, driving device etc., it can be with material on certain travel line, put from feed and form a kind of conveying flow process the emptying point, it both can carry out the conveying of broken loose material, also can carry out the conveying of work piece, except carrying out pure mass transport, can also match with the technological process in each industrial enterprise's production procedure, form rhythmical Detroit automation lane of traffic.
At present, belt conveyer is in operation process, load-transfer device " sideslip " phenomenon usually occurs, it is the sidewise phenomenon of line of centers race that load-transfer device breaks away from conveying belt machine, sideslip not only can cause spreading, and the load-transfer device that easily weares and teares, and shortens its service life, and can cause serious accident when serious, affect normal production operation.
Therefore, belt deflection is subject to people's attention always, has worked out a series of technical schemes that prevent belt deflection, and the correcting device of prior art generally has: deviation regulating idler group, Hydraulic Deviation-correcting Device, the electrical control deviation correcting device of pressing TD75, DTII standard.The deviation regulating idler group of TD75, DTII standard designs and produces by existing industry standard, can reach the purpose of correction through on-site verification, but in use have the defectives such as carrying roller comes off, rotating shaft fracture, connecting rod exercise not harmony; The Hydraulic Deviation-correcting Device flexible movements are controlled, but it is loaded down with trivial details that hydraulic tubing is arranged, and the hydraulic pipe Louis stops up and cause deviation correcting device not move as required, and the defective that the electrical control deviation correcting device exists is that the control line wiring is inconvenient, there are the problems such as signal interference, usually affect normal work production.
Summary of the invention
