Specific embodiment
Core of the present utility model is to provide a kind of coal flow detection device, is capable of detecting when whether device fails,
Avoid being still provided in failure the situation of detection.
In order that those skilled in the art more fully understands the technical solution of the utility model, below in conjunction with accompanying drawing and
Specific embodiment, the coal flow detection device to the application is described in detail explanation.
As shown in Fig. 2 to Fig. 4, represent respectively the axonometric drawing of coal flow detection device, front view that the utility model provides and
Side view.The device includes the structures such as support frame 2, coal stream contactor 1, tablet 3, coal flow sensor 4 and failure sensor 5.
Wherein support frame 2 is connected with other structures, and main fixed supporting role is played to whole device；Other are installed on support frame 2
All parts, rotate connection coal stream contactor 1 on support frame 2, the top of coal stream contactor 1 sets tablet 3, bottom to
Lower extension, can touch the coal stream on conveyer belt.It is mutually permanently connected between coal stream contactor 1 and tablet 3, is may be configured as
Integral structure, rubs so as to drive tablet 3 to rotate certain angle, in coal stream when having coal to pass through with coal stream contactor 1
The rotational angle of tablet 3 keeps relative stability in the case of stability of flow.Coal stream contactor 1 is slim-lined construction, not by outer
Under conditions of power, can keep sagging in the Action of Gravity Field of itself.The letter that coal flow sensor 4 and failure sensor 5 will be detected
Number it is sent out, the working condition for determining coal mining device.
The coal flow sensor 4 and failure sensor 5 for detecting the state of tablet 3 are also set up on support frame 2, coal spreads sense
Device 4 and failure sensor 5 are respectively arranged at the two ends of the rotation direction of tablet 3.Described two ends are not necessarily referring to tablet 3 herein
The both sides of plate face, and refer on its vibration-direction from the point of view of two ends, namely sense can be spread by coal when tablet 3 is rotated
Device 4 and failure sensor 5 are detected.
In use, when passing through without coal, coal stream contactor 1 keeps sagging vertically under gravity, now feels
Plate 3 is answered not rotate；When lower section, to have coal to flow through out-of-date, drives coal stream contactor 1 to rotate, and then rotate tablet 3.Coal
, respectively positioned at the two ends of the rotation direction of tablet 3, in synchronization, tablet 3 can be located for flow sensor 4 and failure sensor 5
Within one or two investigative range among both coal flow sensor 4 and failure sensor 5, detected according to both
Whether corresponding relation, judge the rotational angle of coal stream contactor in rational state.If the long-time of coal stream contactor 1 is using being subject to
Larger abrasion, rotational angle can be gradually reduced, when being reduced to certain degree more than coal flow sensor 4 and failure sensor
5 both detected scope when be issued by alarm, in time remind operator changed, it is to avoid there is economic loss.
Specifically, the utility model provides a kind of coal flow sensor 4 and both the setting sides of failure sensor 5 herein
Formula, as shown in figure 5, when coal stream contactor 1 is in vertical state, coal flow sensor 4 is directed at the plate face of tablet 3, failure sensor 5
Outside alignment tablet 3.Coal flow sensor 4 can detect the presence of tablet 3 when without coaly state, and the nothing of failure sensor 5
Method detects tablet 3；Namely it is 1 that coal flow sensor 4 measures signal, while the signal of failure sensor 5 is 0, it is believed that without coal stream
By.According to the direction that coal stream passes through, failure sensor 5 and coal flow sensor 4 are set gradually, both can be using proximity switch etc.
The induction installation of tablet 3 can be detected.
As shown in fig. 6, when there is coal to pass through, coal stream drives coal stream contactor 1 to swing to the right, makes coal stream contactor 1 to the right
Deflection, and then drive tablet 3 to deflect to the left, when coal stream contactor 1 is normal, tablet 3 can deflect into the institute of coal flow sensor 4
Outside the scope of detection, tablet 3 can be entered within the detection range of failure sensor 5, namely when coal flow sensor 4 is measured
Signal is 0, failure sensor 5 measure signal for 1 when, it is believed that have coal stream pass through, now detect state it is normal.
When coal stream contactor 1 is worn for a long time, even if there is the coal cannot also to rotate enough angles, now failure sensor
5 and coal flow sensor 4 cannot detect tablet 3, namely failure sensor 5 and coal flow sensor 4 measure signal and are 0,
Now think failure of apparatus, the measuring state according to failure sensor 5 and coal flow sensor 4 sends signal to operator, remind
Maintenance in time is changed.
Further, the tablet 3 in the utility model certainly, may be alternatively provided as the other shapes such as triangle in sector.
Angle between the line of coal flow sensor 4 and the line of the rotating shaft of tablet 3, failure sensor 5 and the rotating shaft of tablet 3 is more than sense
Answer 1~15 degree of the angle of plate 3, including two endpoint values.For example, if exceeding coal flow sensor after tablet 3 rotates 5 degree
4 detection range, tablet 3 rotates the detection range into failure sensor 5 after 15 degree, under normal circumstances tablet 3
Corner is more than or equal to 15 degree, and with the increase of wear extent, corner is gradually reduced, until less than 15 degree, but now still greater than 5
Degree, is issued by Failure Alarm, reminds operator to change and works as coal stream contactor 1.
In any of the above-described technical scheme and its in the case of be combineding with each other, coal stream contactor 1 includes the folder being detachably connected
Tight device 11 and induction pieces 12, the top connection tablet 3 of clamping device 11, induction pieces 12 extend downwardly from clamping device 11, directly
Connect and contacted with coal stream.Only need to change induction pieces 12 itself after induction pieces 12 wear and tear, without changing miscellaneous part, with preferable
Economic benefit.
Specifically, induction pieces 12 are the clubs such as iron staff or reinforcing bar, and clamping device 11 is that can clamp induction pieces 12
Tubular structure, induction pieces 12 have opening vertically, and, by bolt tightening, the degree that regulating bolt is tightened can for the both sides of opening
To be adapted to the iron staff of different-diameter, therefore with stronger versatility.
The arc-shaped slot opened up on support frame 2, coal flow sensor 4 and failure sensor 5 are installed in the circle on support frame 2
In deep-slotted chip breaker, coal flow sensor 4 and failure sensor 5 can be slided in arc-shaped slot, so that relative angle is adjusted, to adapt to
The tablet 3 of different shape or size.
The foregoing description of the disclosed embodiments, enables professional and technical personnel in the field to realize or new using this practicality
Type.Various modifications to these embodiments will be apparent for those skilled in the art, determine herein
The General Principle of justice, can in other embodiments realize in the case where spirit or scope of the present utility model are not departed from.Cause
This, the utility model is not intended to be limited to the embodiments shown herein, and is to fit to and principles disclosed herein
The most wide scope consistent with features of novelty.
