Abstract
The utility model provides a coal pipe coal blockage signal detector, which comprises a protective cover formed at the side wall of the coal pipe and a detector arranged on the protective cover. The protective cover hogs out towards the outside of the coal pipe. The utility model prevents a switch from being smashed by coal lumps often, greatly saves the charge of spare parts and the maintenance cost and charge of maintainer, greatly relieves the patrol labor intensity of operators, reduces the unfavorable factors of a coal conveying system in safety aspect and improves the safety and stability of the coal conveying system.
Description
Technical field
The utility model relates to the colliery transmission apparatus, relates in particular to a kind of coal spout chute blockage signal supervisory instrument.
Background technology
The frequent flase alarm of coal spout chute blockage signal detector of coal handling system, the serious distortion of chute blockage signal, and the chute blockage signal switch is often smashed by coal cinder.Original design and mounting means can not adapt to the needs of production scene.
The chute blockage switch of prior art is the baffle-type travel switch that is positioned at the coal spout bottom, on the one hand, the baffle-type travel switch is for a long time in the environment of defeated coal gallery humidity, because defeated coal gallery coal spout place humidity, oxidation are serious, environment is quite big to the detector infringement, can cause deflection of spring or corrosion, cause the frequent bite of travel switch.When a large amount of long-pending coals got lodged in the coal spout place, the baffle-type travel switch of distortion bite may miss operation, therefore caused the alert signal of not transmitting messages behind the chute blockage, even can cause misoperation or tripping.
On the other hand, when gathering coal or big the coal amount is instantaneous when flowing through the chute blockage controller, vibration increases, cause the flase alarm of coal spout chute blockage signal detector easily, and can cause serious mechanical wear to controller itself, seriously, travel switch is often smashed by coal cinder.Therefore, travel switch needs often to change, thereby causes the waste of spare part expense, and has strengthened the work capacity of service personnel.
And, the initial investment expense height of baffle-type travel switch, and need the special messenger to safeguard, so maintenance cost is also very high.
The utility model content
At the defective of prior art, the purpose of this utility model provide a kind of can arduous service and long service life, coal spout chute blockage signal supervisory instrument easy to maintenance.
The coal spout chute blockage signal supervisory instrument that the utility model provides comprises: at the protective cover that the coal spout sidewall forms, described protective cover arches upward to the outside of coal spout; Be installed in the detector on the described protective cover.
Preferably, the height that arches upward of described protective cover is the 200-500 millimeter.
Preferably, the height that arches upward of described protective cover is 350 millimeters.
Preferably, described detector is installed in the arch upward top of portion of described protective cover.
Preferably, described detector comprise detection-sensitive motor and with described detection-sensitive motor bonded assembly shift fork.
Preferably, described protective cover in the size of the opening of coal spout sidewall more than or equal to 610mm * 260mm.
Preferably, the thickness of described protective cover is more than or equal to 10 millimeters.
Preferably, described protective cover and coal spout sidewall are integrally formed.
With respect to prior art, utilize coal spout chute blockage signal supervisory instrument of the present utility model, can avoid switch often to be smashed by coal cinder, save the spare part expense greatly; Adopt coal spout chute blockage signal supervisory instrument of the present utility model, the chute blockage switch can avoid safeguarding in 1-2, saves maintenance specific responsibility people's maintenance cost and maintenance cost; Also alleviated simultaneously operations staff's tour labour intensity greatly; Reduced the unfavorable factor of coal handling system, improved the security and stability of coal handling system at secure context.
Description of drawings
Fig. 1 is the scheme drawing of the coal spout chute blockage signal supervisory instrument in a kind of embodiment of the utility model;
Fig. 2 is that the coal spout chute blockage signal supervisory instrument of using in a kind of embodiment of the utility model carries out the scheme drawing that chute blockage detects.
The specific embodiment
As shown in Figure 1, coal spout chute blockage signal supervisory instrument of the present utility model comprises protective cover 1 and detector 2.
Wherein, protective cover 1 forms at coal spout 3 sidewalls, and described protective cover 1 arches upward to the outside of coal spout 3, the palm that type has seemingly been curled up.Described protective cover 1 can be by making with coal spout 3 sidewall identical materials, for example cast iron etc.Protective cover 1 can be integrally formed with coal spout 3, also can be used as independent parts and be connected on the sidewall of coal spout 3 by connection modes such as welding, bolted connection or riveted joints.
Preferably, the height that described protective cover arches upward is the 200-500 millimeter, so that can hold a certain amount of coal cinder.In preferred implementation of the present utility model, the height that protective cover arches upward is 350 millimeters, is of a size of 610mm * 260mm at the opening of coal spout sidewall.Protective cover can enlarge or dwindle as required in the size of the opening of coal spout sidewall.In order to make protective cover have certain intensity, the thickness of described protective cover is preferably more than or equals 10 millimeters.
And preferably, as shown in Figure 1, detector 2 is installed in the described protective cover top of portion of arching upward, so that will the impact of detector 2 be minimized.
As shown in Figure 2, in the process that coal breakage detects:
Coal stream flows down along coal spout; When coal stream ran into obstruction, coal cinder can be piled up; The coal cinder of piling up can pour in the internal cavity of protective cover 1, sends corresponding chute blockage transducing signal thereby cause detector 2 to controller; According to described chute blockage transducing signal, corresponding controller can be carried out control operation according to the expectant control logic.
Although the utility model is to be described by above-mentioned preferred implementation, its way of realization is not limited to above-mentioned embodiment.Should be realized that under the situation that does not break away from the utility model purport those skilled in the art can make different variations and modification to the utility model.
