Abstract
The utility model discloses a belt conveyor with an alarm device, which comprises a belt conveyor (5) a coal discharge hopper (1) and a coal stoppage alarm. The coal stoppage alarm comprises an alarm circuit with an alarm (6) and a trigger, a proximity switch (3) is arranged on the alarm circuit, the trigger comprises a mounting board (2) and a trigger board (4) hinged with the same, the height of the trigger board (4) is larger than the distance between the upper surface of a cola layer on the belt conveyor (5) and the mounting board (2), and smaller than the distance between the upper surface of a belt of the belt conveyor (5) and the mounting board (2), so that when coal stoppage occurs, the trigger board (4) rotates under gravity to touch the proximity switch so as to start the alarm circuit and the alarm (6) starts warning. Application of the belt conveyor enables timely warning, and thereby safety is greatly improved.
Description
Technical field
The utility model relates to belt feeder, especially a kind of coal cutting off alarm device of belt feeder.
Background technology
Belt feeder is a kind of universal machine, and the material that is widely used in factory transports.Belt feeder also is commonly used to transport coal, and coal drops on the belt feeder from following coal bunker, and belt feeder is transported to preposition again.Owing to produce the existence of going up various factors, make the coal that drops on the belt feeder belt from following coal bunker the situation of fracture often occur,, will bring influence to production if can not in time take measures, existing fortune coal belt feeder does not have warning device, therefore has the not high problem of safety.
The utility model content
The purpose of this utility model solves when the fracture situation appears in fortune coal belt feeder exactly can not in time report to the police the problem that safety is not high.
The technical solution adopted in the utility model is: the belt feeder of band warning device, it comprises belt feeder, be positioned at the following coal bunker of belt feeder top, it is characterized in that it also comprises the coal cutting off alarm device, described coal cutting off alarm device comprises warning circuit that is provided with annunciator and the binary pair that starts warning circuit, described warning circuit is provided with near switch, be fixed on down on the inboard outer wall of coal bunker near switch, binary pair comprises adapter plate and trigger board, adapter plate is fixed on down the top of coal bunker outer wall near switch, trigger board and adapter plate are hinged, the trigger board height is greater than the distance between belt feeder coal seam upper surface and the adapter plate, less than the distance between belt feeder belt upper surface and the adapter plate, make that trigger board is touched near switch activated warning circuit because of gravity rotates when breaking coal, make alarm equipment alarm.
Adopt technique scheme, when belt feeder normally moves, the coal seam of dropping on the belt takes up trigger board down, make trigger board be in heeling condition all the time, do not contact warning device near switch, when occurring disconnected coal situation on the belt feeder, trigger board will fall after rise naturally because of gravity, to contact, thereby start warning device, and remind the operating personal belt feeder fracture situation to occur near switch.
The utility model beneficial effect is: because the utility model adopts the coal cutting off alarm device is set on belt feeder, makes disconnected coal situation in time feed back to operating personal and deal with problems, guarantee to produce normal operation, so the utility model has strengthened the safety of belt feeder.
Description of drawings
Fig. 1 is the utility model structural representation.
Fig. 2 is warning circuit figure.
The specific embodiment
The belt feeder of band warning device, as shown in Figure 1, it comprises belt feeder 5, be positioned at the following coal bunker 1 of belt feeder 5 tops, it also comprises the coal cutting off alarm device, the coal cutting off alarm device comprises warning circuit that is provided with annunciator 6 and the binary pair that starts warning circuit, warning circuit as shown in Figure 2, warning circuit is provided with near switch 3, be fixed on down on the coal bunker 1 inboard outer wall near switch 3, binary pair comprises adapter plate 2 and trigger board 4, adapter plate 2 is fixed on down the top of coal bunker 1 outer wall near switch 3, trigger board 4 is hinged with adapter plate 2, and trigger board 4 height are greater than the distance between belt feeder 5 coal seam upper surfaces and the adapter plate 2, less than the distance between belt feeder 5 belt upper surfaces and the adapter plate 2, make that trigger board 4 is touched near switch activated warning circuit because of gravity rotates when breaking coal, annunciator 6 is reported to the police.
Claims (1)
