Description
Technical Field
The utility model relates to a conveying equipment field especially relates to a compound overspeed device tensioner of bucket elevator afterbody.
Background
The bucket elevator is used for vertically lifting continuous conveying equipment for powdery or small granular materials, and is widely applied to the building material industry, the chemical industry and the coal industry. The upper chain wheel drives the conveying chain to do up-and-down circular motion, the conveying chain is provided with a hopper for bearing materials, the materials are added into the hopper which moves continuously from the tail part, and the materials are lifted to the head part, so that the purpose that the materials are lifted to a specific height for discharging after being loaded at the tail part is achieved. It can be seen from the principle that the normal operation of the elevator bucket elevator conveyor chain must have a tension with proper tension, in the prior art, the tension is provided by the heavy hammer box, because the lifting height of the bucket elevator is different along with the requirements of users, the bucket elevator with one specification uses the same heavy hammer box obviously and not scientifically, the gravity calculated theoretically is not ideal in actual use, the ideal tension is vital to the service life of the conveyor chain and the chain wheel of the bucket elevator, and if only the spring is used, the tension of the spring of the bucket elevator with high lifting height and large specification can not meet the required tension.
SUMMERY OF THE UTILITY MODEL
The utility model aims at providing a not enough to prior art, the utility model aims at providing a compound overspeed device tensioner of bucket elevator afterbody, the reliable tensile force that the tensioning is fit for that provides to improve the life of carrying chain and sprocket, solved ordinary bucket and carried quick-witted spring tensioning and can not satisfy its required tensile problem.
The utility model provides a compound overspeed device tensioner of bucket elevator afterbody, including the lifting machine, be provided with the lift track in the lifting machine, be provided with the lift bucket on the lift track, be provided with afterbody sprocket group on the lift track, drive through afterbody sprocket group and promote the orbital motion, afterbody sprocket group top is provided with the weight case, the weight incasement is provided with the weight, the weight passes the shell connection afterbody sprocket group of lifting machine through the lead screw, be provided with the pressure spring on the lead screw.
The further improvement lies in that: and a spring seat is arranged at the contact position of the elevator and the screw rod, and the upper end of the pressure spring is fixed on the spring seat.
The further improvement lies in that: the lead screw is connected with the tail chain wheel set through a nut, displacement sensors are arranged on two sides of the tail chain wheel set, and whether the tail chain wheel set displaces or not is detected through the displacement sensors.
The further improvement lies in that: and a contact sensor is arranged in the heavy hammer box, and the position condition of the heavy hammer is detected through the contact sensor.
When the tail chain wheel set is upwards floated to be larger during idle running of the bucket elevator, the nut is rotated upwards to enable the pressure spring to compress and then apply downward pressure to the screw rod, so that the tail chain wheel set is forced to move downwards to tension the conveying chain. When the tail chain wheel set has only slight buoyancy in the operation process, the conveying chain of the bucket elevator is in an optimal state suitable for tensioning. When the tail chain wheel set does not float a little and is fixed in the original position to rotate, the nut must be rotated downwards to reduce the pressure of the pressure spring, so that the pressure spring slightly floats to ensure the stable operation of the equipment.
The utility model has the advantages that: the weight box and the screw rod reliably provide a tensioning force suitable for tensioning, so that the service life of the conveying chain and the chain wheel is prolonged, the whole machine operates more stably, the idle work output and faults of equipment are reduced, and the weight box and the screw rod are compact in structure, simple and easy to manufacture.
