Abstract
The utility model belongs to a safe detecting device for detecting the running speed of a belt conveyer, in particular to a belt conveyer speed detecting device, which comprises a belt conveyer, a passive rotary drum and an approach switch. A metal block is fixedly connected to the end side of the passive rotary drum; the approach switch is installed on a fixed support positioned on the lateral surface of the passive rotary drum; the position of the approach switch corresponds to that of the metal block runs to a detection position; and the approach switch is connected with a data acquisition controller through conducting wires. The belt conveyer speed detecting device has the advantages of simple structure, reliable performance, various functions, high detection accuracy, long service life and low failure rate, and can be applied to speed detection and protection for belt conveyers in industries such as metallurgy, coal, mine, cement, electric power, grains and the like.
Description
Technical field
The utility model belongs to the safety detection device, particularly band conveyor speed detector that detects the band conveyor running velocity.
Background technology
Present domestic belt feeder speed detector can be divided into contact and contactless by mounting means: the contact device is installed in the up belt of belt feeder bottom, friction drives roller when mainly walking by belt, speed signal is handled back access relevant device handle.Major defect: (1) complex structure; (2) change not high, the poor stability of survey precision that is caused by friction, slipping of the belt and roller radius.Contactless device: form by the impulse singla sensing head-magnetosensitive probe that is installed in a kind of signal source-magnetic source on the belt and be installed on the sensor fixed support. when belt moves, signal source maintains a certain distance through the impulse singla sensing head and with sensing head, transducing signal enters micro controller system through amplifying by interface.Major defect: (1) software function underaction; (2) the weak shortcoming of magnetic source and magnetosensitive low, micro controller system antijamming capability in probe service life.
The utility model content
The purpose of this utility model is to provide a kind of band conveyor speed detector, and it is simple in structure, dependable performance, and function is more, the accuracy of detection height, long service life, fault rate is low.
The purpose of this utility model is achieved in that a kind of band conveyor speed detector, comprise band conveyor, passive cylinder and near switch, distolateral affixed derby at passive cylinder, be positioned on the fixed support of passive cylinder side and be installed with near switch, position near switch is corresponding with the derby that moves to the detection position, is connecting the data acquisition control instrument near switch by lead.
When band conveyor moves; signal near the switch collection enters the data acquisition control instrument, and the real-world operation speed of band conveyor is calculated in the controller software programming, makes corresponding warning when band conveyor speed is slack-off; when speed is very low or stall when skidding, output action is shut down.
Leading indicator:
1, the running velocity at belt feeder is lower than 90% of normal speed, sends alerting signal, is lower than 60% of normal speed, and the output trip command is shut down.
2, slipping of the belt or fracture, the output trip command is shut down.
The utility model can when causing band conveyor speed mal, in time the notifying operation personnel inspection be handled, and avoids fault to enlarge to cause stopping production in that band conveyor material transportation is improper; In stall phenomenons such as band conveyor skid, can realize stoppage protection equipment.The utility model is installed and used with easy to maintenance.The utility model is simple in structure, dependable performance, and function is more, the accuracy of detection height, long service life, fault rate is low.
The utility model is used for the detection of belt conveyor running velocity, and when the running velocity of detected travelling belt was lower than preset value, it can send and report to the police or shutdown signal, can avoid the generation and the expansion of accident effectively.The running velocity that can be applicable to industry band conveyors such as metallurgy, coal, mine, cement, electric power, grain detects and protection.
Description of drawings
The utility model is described in further detail below in conjunction with accompanying drawing.
Accompanying drawing is a structural representation of the present utility model.
The specific embodiment
A kind of band conveyor speed detector, as shown in drawings, comprise band conveyor, passive cylinder 1 and near switch 3, distolateral affixed derby 2 at passive cylinder 1, be positioned on the fixed support of passive cylinder 1 side and be installed with near switch 3, position near switch 3 is corresponding with the derby 2 that moves to the detection position, is connecting data acquisition control instrument 4 near switch 3 by lead.Data acquisition control instrument 4 is made of LOGO/PLC/DCS.Move to the derby 2 of detection position and be advisable can collect signal safely near switch 3 near the gap between the switch 3.
Claims (3)
1. band conveyor speed detector, comprise band conveyor, passive cylinder (1) and near switch (3), it is characterized in that: at distolateral affixed the derby (2) of passive cylinder (1), be positioned on the fixed support of passive cylinder (1) side and be installed with near switch (3), position near switch (3) is corresponding with the derby that moves to the detection position (2), is connecting data acquisition control instrument (4) near switch (3) by lead.
2. band conveyor speed detector according to claim 1 is characterized in that: data acquisition control instrument (4) is made of LOGO/PLC/DCS.
