Abstract
The utility model discloses an infrared chain falling protective device of a pipeline chain scraper conveyor. The infrared chain falling protective device of the pipeline chain scraper conveyor is characterized by comprising an infrared transmitting tube, an infrared receiving tube and a programmable logic controller (PLC), wherein the infrared transmitting tube and the infrared receiving tube are symmetrically arranged at two sides below motion track of various chain scraper arranged in a drive box body, the infrared receiving tube is connected with the PLC, and the PLC is used for control a power supply of the pipeline chain scraper conveyor. The infrared chain falling protective device of the pipeline chain scraper conveyor is good in sensitivity. The process of stop of the conveyor is very short from chain falling to power off. After a breakdown of chain falling happens, returning to normal is easy.
Description
Technical field
The utility model relates to a kind of pipeline apron conveyer infrared ray and takes off the chain fender guard.
Background technology
The pipeline apron conveyer is the equipment that carries out material transportation in airtight pipeline, is the advanced load transfer device of saving energy consumption, stable performance in the delivery system, is widely used in chemical industry, chemical fibre, and the agricultural chemicals ore, food industry, building materials is waited until industry.Can be conveying powdered, the bulk material such as fine granularity and fritter shape.Can level, inclination and vertical cartel carry.The carrier bar of pipeline apron conveyer connects by chain, by sprocket wheel through chain-driving carrier bar transported material, but chain landing from the sprocket wheel can appear when non-normal use pipeline apron conveyer, damage the problem of scraper plate, affect the use of conveyer.
Summary of the invention
In order to address the above problem, the utility model provides a kind of pipeline apron conveyer infrared ray to take off the chain fender guard.
The technical solution of the utility model realizes in such a way:
A kind of pipeline apron conveyer infrared ray takes off the chain fender guard; it is characterized in that comprising infrared emission tube, infrared receiver tube and PLC; infrared emission tube and infrared receiver tube are symmetricly set on the on the lower side both sides of side of interior each the carrier bar running orbit of drive case; infrared receiver tube is connected with PLC, and PLC is used for control pipeline apron conveyer power supply.
The infrared ray that described infrared emission tube sends is not blocked by the carrier bar in the orbit.
Principle of work: the pipeline apron conveyer is in normal course of operation, infrared receiver tube is received the infrared signal that infrared emission tube sends, infrared signal is converted to electric signal, and PLC receives the electric signal that infrared receiver tube passes out, and connects the apron conveyer power supply.When carrier bar landing from the sprocket wheel, carrier bar downward bias from orbit, block the infrared ray that infrared emission tube sends, infrared receiver tube does not receive infrared ray, PLC does not receive the electric signal that infrared receiver tube passes out, cut off immediately the conveyer working power, conveyer quits work.
Beneficial effect: the utility model device sensitivity is high, and from taking off chain to cutting off the electricity supply, the out-of-work process of conveyer is extremely short, recovers normally also to be easy to after taking off the chain fault.
Description of drawings
Fig. 1 is that pipeline apron conveyer infrared ray takes off chain fender guard structure front elevation.
Among Fig. 1,1-carrier bar, 2-infrared emission tube, 3-infrared receiver tube, 4-drive case, 5-PLC.
Fig. 2 is that pipeline apron conveyer infrared ray takes off chain fender guard structure side view.
Among Fig. 2,1-carrier bar, 2-infrared emission tube, 4-drive case.
The specific embodiment
Following the utility model is further described embodiment in connection with accompanying drawing:
As illustrated in fig. 1 and 2; a kind of pipeline apron conveyer infrared ray takes off the chain fender guard; it is characterized in that comprising infrared emission tube 2, infrared receiver tube 3 and PLC 5; infrared emission tube 2 and infrared receiver tube 3 are symmetricly set on the on the lower side both sides of side of drive case 4 interior each carrier bar 1 running orbit; infrared receiver tube 3 is connected connection with PLC, PLC 5 is used for control pipeline apron conveyer power supply.
The infrared ray that described infrared emission tube 2 sends is not blocked by the carrier bar 1 in the orbit.
The pipeline apron conveyer is in normal course of operation, infrared receiver tube 3 is received the infrared signal that infrared emission tube 2 sends, infrared signal is converted to electric signal, and PLC 5 receives the electric signal that infrared receiver tube 3 passes out, and connects the apron conveyer power supply.When carrier bar 1 landing from the sprocket wheel, carrier bar 1 downward bias from orbit, block the infrared ray that infrared emission tube 2 sends, infrared receiver tube 3 does not receive infrared ray, PLC 5 does not receive the electric signal that infrared receiver tube 3 passes out, cut off immediately the conveyer working power, conveyer quits work.
The utility model device sensitivity is high, and from taking off chain to cutting off the electricity supply, the out-of-work process of conveyer is extremely short, recovers normally also to be easy to after taking off the chain fault.
