Abstract
The utility model provides a belt slipping alarm device of a coal feeder. The belt slipping alarm device of the coal feeder comprises a channel steel (101). A connection rod (107) is fixed on the channel steel (101), a pair of driving wheels (104) is fixed on the rod head portion of the connection rod (107), the driving wheel (104) is connected with a driven wheel (102) through a belt (103), the driven wheel (102) extends out of the outer portion of the coal feeder device, a cam (105) is installed on the driven wheel (102), and a rotating speed measurement device (106) is installed at the stroke position of the cam (105) and connected with a programmable logic controller (PLC) (107). The belt slipping alarm device of the coal feeder can more accurately collect a signal of belt slipping so that a user is reminded of the belt abnormal information in time.
Description
Technical field
The utility model relates to feeder device technique field, particularly a kind of feeder slipping of the belt warning device.
Background technology
The device of existing detection feeder coal supply is, install one on feeder belt top and detect the baffle plate switch that belt has coal, when on the belt coal being arranged, baffle plate turning is pushed down travel switch, then the travel switch output signal is delivered among the DCS (Distributed Control System), does logic and judge in DCS.This logic be generally have on the belt coal signal and feeder run signal mutually with judge whether coal is arranged on the feeder belt.But the defective of design is like this: have the switch of coal to be driven by the iron plate that is installed in belt top on the belt, when on the belt coal being arranged, just can send signal, so when skidding occurring in the feeder belt operational process, there are coal signal and feeder run signal all to exist simultaneously on the belt, cause logic to judge that feeder still at coal supply, so just is unfavorable for that the operation personnel find that in time the feeder belt is unusual.
The utility model content
The utility model provides a kind of feeder slipping of the belt warning device, to gather more exactly the slipping of the belt signal.
To achieve these goals, the utility model provides following technical scheme:
A kind of feeder slipping of the belt warning device, it comprises: channel-section steel, fix a pipe link on the described channel-section steel, the club head of described pipe link is fixed a pair of driving wheel, driving wheel is connected by belt with flower wheel, and flower wheel stretches out the outside of feeder device, on the described flower wheel cam is installed, rotation-speed measuring device is installed at stroke place at cam, and described rotation-speed measuring device is connected with PLC (Programmable Logic Controller).
By implementing above technical scheme, have following technique effect: the feeder slipping of the belt warning device that the utility model provides gathers the slipping of the belt signal, more exactly with timely prompting belt abnormal information.
Description of drawings
The structural representation of the feeder slipping of the belt warning device that Fig. 1 provides for the utility model.
The specific embodiment
In order better to understand the technical solution of the utility model, describe the embodiment that the utility model provides in detail below in conjunction with accompanying drawing.
The utility model embodiment provides a kind of feeder slipping of the belt warning device, as shown in Figure 1, comprise: channel-section steel 101, fix a pipe link 107 on the described channel-section steel 101, the club head of described pipe link 107 is fixed a pair of driving wheel 104, driving wheel 104 is connected by belt 103 with flower wheel 102, flower wheel 102 stretches out the outside of feeder device, on the described flower wheel 102 cam 105 is installed, rotation-speed measuring device 106 is installed at stroke place at cam 105, and described rotation-speed measuring device 106 is connected with PLC107.
Utilize the interior existing PLC of coder and feeder to programme.In order to guarantee reliability, measurement signal is sent into feeder PLC, in PLC, programme, the pulse of input is judged slipping of the belt when being lower than the fixed pulse definite value, output slipping of the belt signal by pulse monitoring logical block, this signal enters logic to be judged, with the prompting related personnel.
Above a kind of feeder slipping of the belt warning device that the utility model embodiment is provided is described in detail, for one of ordinary skill in the art, thought according to the utility model embodiment, all will change in specific embodiments and applications, in sum, this description should not be construed as restriction of the present utility model.
