Description
Technical field
The present invention relates to a kind of auxiliary device of band conveyor, specifically a kind of downward belt conveyor auxiliary braking friction damping device.
Background technology
At present the brake mode of China's downward belt conveyor has three kinds of electric power, hydraulic pressure and fluid power, and fluid power is more widely used.Conveyer is realized two-stage braking by hydraulic brake and mechanical hatching gate.Produce sliding force because the gravity of downward belt conveyor convey materials makes top set's load-transfer device, the in the situation that especially large at oblique angle, haul distance being long, sliding force will substantially exceed the running resistance of load-transfer device, and drive motor is moved under generating state.In the time shutting down braking, unnecessary sliding force will all act on drg, and brake wheel temperature is raise, and the accident of brake failure and driving even occurs.
Summary of the invention
The present invention, in order to solve downward belt conveyor unnecessary sliding force problem in lower fortune process, provides a kind of downward belt conveyor auxiliary braking friction damping device.
The present invention is achieved through the following technical solutions: downward belt conveyor auxiliary braking friction damping device, formed by damping frame, V-type carrier roller frame and two spring-dampers,
Described V-type carrier roller frame comprises two the side carrying rollers and the middle carrying roller that are supported on carrier roller frame base, and two side carrying rollers and middle carrying roller enclose and form a V-type groove;
Described damping frame comprises two channel-section steels that are set in parallel in stay bearing plate below, some damper bars, described some damper bars are supported in stay bearing plate top by some support bars, the length direction of damper bar and Belt Conveying direction are in the same way, and some damper bars form damper bar portion in the middle of two side damper bar portions and, in the middle of two side damper bar portions and one, damper bar portion encloses groove and the V-type angle of the v-groove, measure-alike of formation; The two ends, channel-section steel below of one side are fixed with respectively two connecting panels, all have two damping frame connecting bores that match with the former carrier roller frame mounting hole of frame on each connecting panel;
Described spring-damper comprises spring pedestal, is vertically fixed on lower cylinder, the downward opening retracting cylinder being sheathed in lower cylinder at spring pedestal middle part, between described lower cylinder and retracting cylinder, be connected by coil tension spring, retracting cylinder top is provided with screw rod, and spring pedestal two ends respectively have a base installing hole matching with damping frame connecting bore;
V-type carrier roller frame is supported and is fixed on two spring-damper tops by screw rod.
When concrete use, the former carrier roller frame in frame is removed at interval, connecting panel on the channel-section steel of one side is installed on by damping frame connecting bore on the mounting hole of the former carrier roller frame of frame, adjustment is positioned on same oblique line the V-type groove of V-type carrier roller frame and former carrier roller frame, and the groove of damping frame is a little less than the V-type groove of V-type carrier roller frame.
The material of carrying when downward belt conveyor is when less, and the sliding force that branch's load-transfer device produces is less than the running resistance of load-transfer device, and V-type carrier roller frame of the present invention only plays the effect of support; The material of carrying when downward belt conveyor is when more, especially the in the situation that large at oblique angle, haul distance being long, the sliding force that branch's load-transfer device produces is greater than the running resistance of load-transfer device, but because the gravity of material is greater than the elastic force of coil tension spring on spring-damper, V-type carrier roller frame is pressed down, damper bar generation damping friction force on belt and damping frame, overcomes downward belt conveyor unnecessary sliding force in lower fortune process.
Downward belt conveyor auxiliary braking friction damping device of the present invention, can effectively overcome downward belt conveyor unnecessary sliding force in lower fortune process, avoid motor to move under generating state, prevent the more and more faster phenomenon of belt in load overload situation, avoid runaway accident, played the effect of auxiliary braking, reducing speed.
