Specific implementation mode
To make the objectives, technical solutions and advantages of the present invention clearer, below by accompanying drawings and embodiments,
The present invention will be further described in detail.However, it should be understood that specific embodiment described herein is only used to solve
The utility model is released, the range being not intended to limit the utility model.
Unless otherwise defined, all technical terms and scientific terms used herein and the skill for belonging to the utility model
The normally understood meaning of technical staff in art field is identical, and terminology used in the description of the utility model herein is only
It is to describe the purpose of specific embodiment, it is not intended that in limitation the utility model.
As shown in Figure 1, a kind of drag conveyor skews protective device, including a kind of drag conveyor skews protective device,
Including power supply 1, control cabinet 2, control button 4,12, two flight chains 11 of drag conveyor babinet, several circuit lines and
Several scraper plates 13, the flight chain 11 are mutually parallel with place plane；The power supply 1 passes through circuit with control cabinet 2
Line connects；The control button 4 is connect with control cabinet 2 by circuit line；The scraper plate 13 and flight chain 11 is positioned over
Inside drag conveyor babinet 12；Further include the alarm 5 being connect with control cabinet 2, be fixedly connected with drag conveyor babinet 12
Holder 8, driving rocker 7 and microprocessor 3；The holder 8 is solid above the one end in 12 outside of drag conveyor babinet
Dingan County is equipped with a sensor stand 10 vertically upward；The holder 8 is on one end of 12 inside of drag conveyor babinet
Side is installed with bearing block；Bearing 9 is installed inside the bearing block；
From above-mentioned structure design, we can solve the fracture of scraper plate 13 and flight chain by efficient alarm system
The problem of 11 chain rupture；It is simple and effective.
10 upper end of sensor stand is equipped with one and the motor message of driving rocker 7 is transmitted to control by circuit line
The sensor 6 of 2 internal microprocessor 3 of case processed, driving rocker 7 are monitored with realizing with sensor 6 to transmit the movement of scraper plate 13
Match, whether 3 monitors sensors in real time of microprocessor, 6 signal synchronizes and time-out, and compared with setting value, when scrapper conveyor is run
When, driving rocker 7 does fan-shaped swing under the drive of scraper plate 13, while sensor 6 sends out pulse signal and is transmitted to control cabinet
2.When scraper oblique-pulling degree is more than when normal permissible value or chain rupture occur and alarm or shutdown.
The driving rocker 7 is connect with bearing 9, the upper end extension of driving rocker 7 it is horizontal with babinet and with biography
One end of sensor 6 is relatively close, and the intermediate extension of driving rocker 7 is connect with the bearing in bearing block, the lower end of driving rocker 7
It extend into 12 inside of drag conveyor babinet and the side for leaning on close in scraper plate 13 is set.
The holder 8 is in horizontal positioned；Holder 8 is connected by screw bolts with drag conveyor babinet 12, facilitates fixing lock
Tightly.
