Abstract
The utility model relates to a coal-returning protection device of a belt conveyor. The coal-returning protection device of the belt conveyor comprises a coal blocking plate, a coal returning protection handle and a movement detecting switch, wherein the coal blocking plate is fixed on a position, at the front end of a tail end rotary drum of the belt conveyor, of a machine tail frame. The bottom end of the blocking plate is at a certain height away from the top of a belt. The coal returning protection handle is arranged on a position, between the tail end rotary drum and the coal blocking plate, of the machine tail frame. One side of the coal returning protection handle is close to the coal blocking plate and is electrically connected with the movement detecting switch. After the coal-returning protection device of the belt conveyor is installed, the phenomenon that the belt is scratched by returning coal or other hard objects is avoided, time affected by electromechanical accidents is shortened, and electromechanical safety is also improved.
Description
Technical field
The utility model relates to the coal mine equipment field, the concrete belt protection device that relates to a kind of belt feeder.
Background technology
At present, the coal master transports belt feeder along the line lap-joint and occurs belt phenomenon of the unrestrained end of coal sometimes, and belt feeder is taken back coal and then stopped up aircraft tail cylinder, causes the belt feeder heavy duty to shut down or What is more scratches belt and cause great dynamo-electric accident.Existing belt feeder has only been installed " four protection stream oriented devices " traditionally, can not play and take back the coal protection.
Summary of the invention
The purpose of this utility model provides belt feeder and returns the coal fender guard; described time the coal fender guard comprises spillplate, returns coal protection handle, detects step switch; described spillplate is fixed on the aircraft tail shelf of belt feeder aircraft tail cylinder front end; the bottom is apart from end belt top certain altitude; return coal protection handle and be arranged on the aircraft tail shelf between aircraft tail cylinder and the spillplate, the nearly spillplate of a side joint that returns coal protection handle is electrically connected with the detection step switch.
Preferably, described spillplate is apart from aircraft tail cylinder front end 5m, and apart from end belt top 30mm, the width of spillplate is 1.2-1.6 m.
After having installed of the present utility model time coal fender guard, avoided stopping up aircraft tail cylinder and causing the long-pending coal difficulty of cleaning, also improved mechanical and electrical safety, shortened the dynamo-electric accident impact time, guaranteed main working well because of taking back the coal phenomenon; Taking back coal also can cause hard thing to scratch belt and cause great dynamo-electric accident sometimes; after installing back the coal protection; avoid back coal or other hard things to scratch the belt phenomenon; both shorten the dynamo-electric accident impact time and also improved mechanical and electrical safety; in actual applications; after returning coal protection installation, obtained good result.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
The specific embodiment
As shown in Figure 1; belt feeder returns the coal fender guard; described time the coal fender guard comprises spillplate 3, returns coal protection handle 4, detects step switch 5; described spillplate 3 is fixed on the aircraft tail shelf of belt feeder aircraft tail cylinder 1 front end; the bottom is apart from end belt 2 top 30mm; returning coal protection handle 4 is arranged on the aircraft tail shelf at 5m place between aircraft tail cylinder 1 and the spillplate 3; the nearly spillplate 3 of a side joint that returns coal protection handle 4 is electrically connected with detecting step switch 5, detects step switch 5 and is electrically connected with the belt feeder switch by control cable 6.
During concrete enforcement; belt feeder returns the coal fender guard and is installed on the aircraft tail shelf at belt feeder aircraft tail cylinder 1 front end 5m place; when end belt 2 was taken back coal, coal touched spillplate 3, and spillplate 3 touches back coal protection handle 4; make back coal protection handle 4 opened with certain angle; detect control belt feeder switch SELF CL after the action that step switch 6 detects back coal protection handle 4, the belt feeder shutdown is during coal on the belt of the intact end for clearance; open belt, avoid causing dynamo-electric accident.
