In addition, the tensioning device of the bucket elevator return pulley further has the advantages of being low in manufacturing cost, few in consumed materials, and compact in structure, saving energy and the like. The tensioning device of the bucket elevator return pulley can be applied to small and medium bucket elevators and large bucket elevators, and is suitable for wide application.
Description
Technical field
The utility model relates to a kind of conveying machinery equipment technical field, particularly a kind of tightening device of bucket elevator return pulley.
Background technology
When the traction piece of bucket elevator belongs to plate chain haulage spare or loop chain traction piece, when the specification of these two kinds of parts arrives certain limit greatly, during the tooth phase interlock of plate chain and loop chain nodal axisn and great wheel and tail wheel, the straight-line motion of work traction piece becomes circular movement, can produce velocity contrast, and the impulse oscillation of generation velocity contrast, vibration passes to return pulley and great wheel through traction piece, cause the vibration of return pulley and great wheel, tightening device such as the disclosed a kind of chain bucket hoist afterbody automatic takeup of CN200920171902.6 of existing return pulley, the tailing axle that comprises afterbody casing below, two tail sprockets are installed on the tailing axle, are it is characterized in that: on the tailing axle in described two tail sprockets outside, a weighting distribution wheel is installed respectively.Its weak point is: can not eliminate vibration, can not effectively reduce the impulse oscillation of traction piece, vibration usually destroys the Transmission of return pulley tightening device and great wheel, causes fault, makes to produce and interrupts.
The utility model content
In order to solve the above-mentioned problems in the prior art, the utility model provides a kind of return pulley tightening device that can realize, the tensioning serviceability that not only has return pulley, make return pulley and traction piece not loosening, can also reduce the impulse oscillation of traction piece, exempt the fault that vibration causes, and at the bottom of the low consumptive material of cost, compact conformation, advantage such as energy-conservation.
In order to realize the foregoing invention purpose, the technical solution of the utility model is: a kind of tightening device of bucket elevator return pulley, comprise afterbody housing, slide plate and tailing axle bearing, on the described afterbody housing upper bracket is set, described upper bracket middle part is provided with through hole, is provided with screw rod in this through hole, and described screw rod is provided with nut, spring pressuring plate, spring and lower bracket, described lower bracket is connected with described slide plate, and described slide plate is connected with described tailing axle bearing.
Described afterbody housing is provided with scale mark.
Described nut adopts black nut.
The two ends of described screw rod arrange pin-and-hole, are provided with pin in this pin-and-hole.
Make the compressed generation elastic force of spring by adjusting screw rod, the elastic force of spring is delivered to tailing axle by slide plate, driving component is produced tension force, after the running when return pulley produces vibration, vibration is by spring absorptive amplitude and vibratory force, because the compressed traction piece to bucket elevator of spring has produced constant tension force, vibration is eliminated.Bucket elevator is normal operation under constant tension force in a long time.
The utility model screw take-up is easy to adjust, quick, the tensioning serviceability that not only has return pulley, make return pulley and traction piece not loosening, can also reduce the impulse oscillation of traction piece, exempt the fault that vibration causes, and at the bottom of the low consumptive material of cost, compact conformation, advantage such as energy-conservation, this device can either use at middle-size and small-size bucket elevator, can use at large-scale bucket elevator again, be fit to extensively use.
Description of drawings
Below in conjunction with accompanying drawing the utility model is further described:
Fig. 1 is main TV structure scheme drawing of the present utility model;
Fig. 2 is left TV structure scheme drawing of the present utility model.
The specific embodiment
