Description
Technical field
Fender guard when the utility model relates to a kind of conveyer generation ruptured belt, especially a kind of belt break protection device for belt conveyor.
Background technology
Belt conveyer has become the main load transfer device of bulk material and lump material.Along with conveyer is towards growing fed distance, carrying greatly the future development at inclination angle, due to the long-term work of load-transfer device, high loaded process, the load-transfer device series of factors such as error of tensioning and artificial maintenance too, belt fracture accident odds greatly increased more in the past.
For this type of accident, main solution is that belt break protection device is installed, as " broken belt catcher for electro-hydraulic control type belt conveyor ", " belt conveyor lower broken belt protection device ", " fault-belt catching device of belt conveyer " etc.But there is following defect in these existing fender guards or technology:
1, rely on the belt judgement belt fracture that drives in the wrong direction, and the belt conveyer band material of going up a hill is when start, and exists belt to drive in the wrong direction, and there will be and arrests by mistake;
2, arresting agency movable parts is more, and dust and material can block movable part motion, reduce the life-span of device and arrest reliability;
While 3, arresting belt, brake area is little, and braking force is concentrated, and causes belt tearing;
4, coal area is little excessively, affects the conveying of bulk materials, can cause fender guard to damage, even conveyer accident when serious.
?
Summary of the invention
The purpose of this utility model is the deficiency that overcomes prior art, and a kind of belt break protection device for belt conveyor is provided.This device is used belt tension judgement belt fracture, arrests levels belt when ruptured belt simultaneously, and arresting agency is reliable, simple in structure, and movable parts is few, guarantees larger coal area excessively, and belt fracture signal can be provided.
The technical scheme that the utility model taked is for achieving the above object: a kind of belt break protection device for belt conveyor comprises side plate, lower arresting agency, upper arresting agency, stop gear and position transduser, it is characterized in that: side plate is arranged on the both sides of belt holder, lower arresting agency comprises lower swing arm and the lower bridle being arranged between side plate; Lower swing arm front end pressure head is housed below lower arresting agency, and lower swing arm two ends spindle nose is arranged in the reserved axis hole of side plate, and lower swing arm can swing up and down between side plate; Lower bridle is arranged on the below of lower belt, and is connected with side plate by bolt group; Front end at lower swing arm is provided with snub pulley; Lower swing arm contacts with the upper surface of lower belt by snub pulley; Described upper arresting agency comprises top link and the upper bridle being arranged between side plate, and top link front end pressure head is housed above upper arresting agency, and top link two ends spindle nose is arranged in the reserved axis hole of side plate, and top link can swing up and down between side plate; Upper bridle is arranged on the top of belt, and is connected with side plate by bolt group; Front end at top link is provided with upper supporting roller; Top link contacts with the lower surface of upper belt by upper supporting roller; In top link rear end, weight arm is housed, counterweight is installed on weight arm, counterweight gravity makes top link drive upper belt upwards to swing; A side at side plate is equipped with stop gear and position transduser.
