Embodiment
1-3 further illustrates to ribbon conveyer coal piling protecting device of the present invention below in conjunction with the accompanying drawings.
As shown in figure 1, ribbon conveyer coal piling protecting device include frame 1, roller rack 2, middle idler roller 3, a pair with
Side roller 4, the belt 10 that the left and right sides of carrying roller 3 is symmetrically connected, side roller 4 are suspended on roller rack 2 by suspension arrangement, hang
Hang device includes hook 5 and elastic device 6, links up with 5 both ends and is connected respectively with roller rack 2 and elastic device 6, elastic device
6 other end is connected with side roller 4, and the elastic device 6 can be spring, or elastic threads；The ribbon conveyer coal piling
Protection device also includes pressure monitoring device 7 and the controller 9 being electrically connected by wire 8, pressure monitoring device 7 are arranged on
On the lower methods, rack 1 of the middle idler roller 3.
In other words, by middle idler roller 3 and the idler machining formed with the side roller 4 that the both sides of middle idler roller 3 are symmetrically connected, its both ends by
Elastic device 6 and hook 5 are suspended on roller rack 2, and the lower section of middle idler roller 3 is equipped with pressure monitoring device 7, and controller 9 is by leading
Line 8 is connected with pressure monitoring device 7.Elastic device 6 bear middle idler roller 3, side roller 4, on belt 10 and belt 10 coal weight
Power, this gravity increase as coal increases, and the length that elastic device 6 is stretched increases therewith, the height of middle idler roller 3 then with
Reduction.
When the ribbon conveyer normal operation of lower section, i.e., non-coal piling when, the coal amount of the top of belt 10 is smaller.Now, bullet
The power that property device 6 is born is smaller, and its curtailment being stretched is so that the height of middle idler roller 3 drops to pressure monitoring device 7
On.I.e. pressure monitoring device 7 is not readily accessible to middle idler roller 3, can not also measure coal gravity.Now judged by controller 9
Ribbon conveyer is in the state of normal operation.
As shown in figure 3, when lower section ribbon conveyer breaks down out of service, and top ribbon conveyer 11 is normally transported
During row, top ribbon conveyer 11 constantly throws coal to the belt 10 of lower section ribbon conveyer, due to lower section belt conveying
Machine in time can not transport coal, and coal piling phenomenon just occurs.At coal piling process initial stage, with the top of belt 10 constantly accumulation coal
Charcoal, gravity suffered by dump 12 constantly increase, and elastic device 6 is stretched, and the height of middle idler roller 3 constantly declines and is finally down to pressure
In monitoring device 7, pressure monitoring device 7 supports middle idler roller 3, and pressure signal is transmitted to controller 9 by wire 8,
Coal piling alarm signal is sent by controller 9.Its is stable and reliable in work, and when the top coal amount of belt 10 continues to increase, pressure monitoring
The pressure of device 7 constantly increases, thus can be judged by pressure size the top of belt 10 accumulation coal amount number, and send out in time
Go out alarm signal.The technical scheme is safe and reliable when running, and suitable for underground bad working environments condition, and can monitor the more of coal piling amount
It is few.
According to Fig. 2, as the further improvement of this programme, pressure monitoring device 7 includes briquetting 71, pressure sensor
72 and base 73, base 73 be fixedly installed in frame 1, briquetting 71 is fixed on base 73, and pressure sensor 72 is located at briquetting

When middle idler roller 3 is dropped on briquetting 71, its contact surface is larger for other schemes, when briquetting 71 supports middle idler roller 3,
Prevent because support force is excessive, and contact surface is small and stress concentration, cause carrying roller to be destroyed by briquetting 71.
In such scheme, it is preferable that briquetting 71 is elastic press, can be made up of resin, rubber etc..When middle idler roller 3
When falling on elastic press, it is possible to certain buffer protection function is played to middle idler roller 3.
Other preferred schemes can certainly be used, briquetting 71 can be with certain rigid metal derby, its upper surface
Apply one layer of elastomeric material, such as resin, rubber etc..Like this, the existing certain intensity of briquetting 71, middle idler roller 3 can be risen
To good supporting role, and itself is unlikely to deform, and is not easy to be subject to crushing, and and can plays a protective role to middle idler roller 3.
As a further improvement on the present invention, as Fig. 1, controller 9 are fixedly installed in the outside of frame 1, naturally it is also possible to Gu
