Description
Technical field
The present invention relates to the auxiliary device of a kind of belt conveyor, specifically a kind of downward belt conveyor auxiliary braking friction damping device.
Background technology
The mode of braking of China's downward belt conveyor has electric power, hydraulic pressure and fluid power three kinds at present, and fluid power is more widely used.Conveyer is realized two staged braking by hydraulic brake and mechanical hatching gate.Owing to the gravity of downward belt conveyor conveying material makes top set conveyer belt produce sliding force, in the case of especially big at oblique angle, haul distance length, sliding force will substantially exceed the running resistance of conveyer belt, make driving motor run under generating state.When parking brake, unnecessary sliding force will all act on the brake, make brake wheel temperature raise, and brake failure and the accident of driving even occur.
Summary of the invention
The present invention is to solve the sliding force problem that downward belt conveyor is unnecessary during lower fortune, it is provided that a kind of downward belt conveyor auxiliary braking friction damping device.
The present invention is to be achieved through the following technical solutions: downward belt conveyor auxiliary braking friction damping device, is made up of damping frame, V-type carrier roller frame and two spring-dampers,
Described V-type carrier roller frame includes that two the side carrying rollers being supported on carrier roller frame base and a middle carrying roller, two side carrying rollers and middle carrying roller enclose and set one V-groove of formation；
Described damping frame includes two channel-section steels being set in parallel in below gripper shoe, some amortisseur bars, described some amortisseur bars are supported in above gripper shoe by some support bars, the length direction of amortisseur bar is with Belt Conveying direction in the same direction, and some amortisseur bars forms amortisseur bar portion in the middle of amortisseur bar portions, two sides and, in the middle of amortisseur bar portion, two sides and one, amortisseur bar portion encloses the groove setting formation and V-groove angle, equivalently-sized；It is respectively fixed at two ends with a connecting plate below the channel-section steel of side, each connecting plate all has the damping frame connecting hole that two carrier roller frame installing holes former with frame match；
Described spring-damper includes spring pedestal, is perpendicularly fixed at the lower cylinder in the middle part of spring pedestal, the downward opening retracting cylinder being sheathed in lower cylinder, it is connected by coil tension spring between described lower cylinder and retracting cylinder, retracting cylinder top is provided with screw rod, and spring pedestal two ends respectively have a base installing hole matched with damping frame connecting hole；
V-type carrier roller frame is fixed on above two spring-dampers by screw support.
Time specifically used, the former carrier roller frame in frame is removed at interval, connecting plate on the channel-section steel of side is installed on the installing hole of the former carrier roller frame of frame by damping frame connecting hole, adjust and the V-groove of V-type carrier roller frame and former carrier roller frame are positioned on same oblique line, and the groove of damping frame is slightly below the V-groove of V-type carrier roller frame.
When the material of downward belt conveyor conveying is less, the sliding force that branch's conveyer belt produces is less than the running resistance of conveyer belt, and V-type carrier roller frame of the present invention only plays the effect of support；When the material of downward belt conveyor conveying is more, in the case of especially big at oblique angle, haul distance length, the sliding force that branch's conveyer belt produces is more than the running resistance of conveyer belt, but owing to the gravity of material is more than the elastic force of coil tension spring on spring-damper, to press under V-type carrier roller frame, belt and the amortisseur bar generation damping friction power on damping frame, overcome the sliding force that downward belt conveyor is unnecessary during lower fortune.
Downward belt conveyor auxiliary braking friction damping device of the present invention, can be efficiently against the sliding force unnecessary during lower fortune of downward belt conveyor, motor is avoided to run under generating state, prevent the phenomenon that belt in the case of overload is the fastest, avoid runaway accident, play the effect of auxiliary braking, reducing speed.
