Technical Field
The utility model relates to a chain protection detecting system of bucket elevator. Belongs to the technical field of transmission equipment detection.
Background
The bucket elevator is a continuous conveying machine which utilizes a series of hoppers fixed on the traction piece yarn sample to convey powdery, granular and blocky materials in the vertical direction or under a large inclination angle condition, and is called as a bucket elevator or an elevator for short. The device mainly comprises a machine shell, a traction piece (belt or chain), a hopper, a driving wheel, a direction-changing wheel, a tensioning device, a driving device and other components. The bucket elevator is widely applied to various bulk material conveying industries and is commonly used for vertical lifting of bulk materials. The main advantages are simple structure, convenient maintenance, low energy consumption, small volume, small occupied area, closed transportation, flexible arrangement, wide range of practical materials and the like.
At present, no hopper chain breakage alarm device is equipped on the domestic bucket elevator, the breakage of the hopper chain is completely observed and found by visual observation of field operators or inspection personnel, artificial observation errors and working errors are inevitable, and therefore the mischief after the breakage of the bucket elevator chain cannot be avoided.

Detailed Description
The present invention will be described in further detail with reference to the following embodiments.
As shown in fig. 1, 2, the utility model relates to a bucket elevator chain protection detecting system, including installing 220V power circuit breaker 1 in the bucket elevator control box, proximity switch 2, first auxiliary relay 3, second auxiliary relay 4 and time relay 5, proximity switch 2 installs in bucket elevator driven gear department to weld a metal dog and cooperate with it on the gear, calculate the bucket elevator and rotate round required time T1 from the driven gear when normal operating, power circuit breaker 1 receives on the power of bucket elevator, with the new protection detecting system that increases of control.
First auxiliary relay 3, the mutual parallelly connected setting of second auxiliary relay 4 and time relay 5's coil, wherein first auxiliary relay 3's coil and proximity switch 2 are established ties, and first auxiliary relay 3's contact and time relay 5's coil are established ties, and time relay 5's contact and second auxiliary relay 4's coil are established ties, and second auxiliary relay 4's contact links to each other with an audible-visual annunciator 6, simultaneously among the contact cluster of second auxiliary relay 4 enters auger motor control circuit, stops the auger motor when the switch-on.
When the system is put into operation by power transmission, the detection device starts to detect: the first intermediate relay is electrified, the normally open contact is closed, and the time relay starts to time; when the detection switch receives the stop block signal, the normally-closed point of the detection switch is disconnected, the first intermediate relay is powered off, the normally-open contact is disconnected, and the time relay coil is reset when powered off. When the detection switch is within the set time T2 of the time relay, and no stop signal is detected, the time relay is closed in a delayed mode, the coil of the second intermediate relay is electrified, the normally open point is closed, and the audible and visual alarm gives out audible and visual alarm; and (5) disconnecting the normally closed point and stopping the packing auger at the upstream.
In addition to the above embodiments, the present invention also includes other embodiments, and all technical solutions formed by equivalent transformation or equivalent replacement should fall within the protection scope of the claims of the present invention.
