Abstract
The utility model relates to the technical field of bucket elevators, and discloses a tensioning device of a bucket elevator. The tensioning device comprises fall wheels, fall wheel guide rails, bearing seats, tension adjusting springs, adjusting bolts, sealing boxes and spring shields. The tension adjusting springs and the adjusting springs are arranged on the outer side of a barrel, tension force is applied to the bearing seats through the tension adjusting springs, and accordingly size of the tension force of the bucket elevator is changed along with increase of bearing capacity, and overload quantity of the bucket elevator is increased. The shields are arranged on the outer sides of the tension adjusting springs, so that the springs are prevented from flying out in the operation process, and potential safety hazards are eliminated; the sealing boxes are added at the position of a connecting shaft of the fall wheels, so that elevated materials are prevented from leaking out, and abrasion of the tensioning device is reduced. Use efficiency of the bucket elevator is improved, the tension force of the bucket elevator is adjusted automatically according to the size of the bearing capacity, and difficulty in repair and maintenance of the fall wheels of the bucket elevator is lowered.
Description
Technical field
The utility model relates to bucket elevator technical field, specifically a kind of swelling device of bucket elevator.
Background technology
Bucket elevator is by motion parts (hopper and conduction chain), form with the top section of driving chain wheel, compresses lower section with take-up pulley, intermediate casing, actuating device, check brake equipment etc., its hopper is that discontinuous is arranged, utilize " taking method " to load, " centrifugal " discharging.The swelling device of bucket elevator is generally divided into: the built-in balance weight iron swelling device of bearing shell and external lever swelling device.
All there is certain drawback in these two kinds of tensioner modes in actual use.Wherein: the problem that the built-in balance weight iron swelling device of bearing shell exists is as follows:
1) adopt bearing shell to connect expansion tightening wheel and clump weight, easy to wear and maintenance in operational process, maintenance difficulty;
2) overload capacity is poor, easily causes chain derailing during overload;
3) expanding force is constant force, has increased the wearing and tearing of chain, wastes energy simultaneously.
The problem that external bearings lever swelling device exists is as follows:
1) overload capacity is poor, easily causes lever to damage during overload;
2) expanding force is constant force, has increased the wearing and tearing of chain, bearing shell, wastes energy;
3) take up room large, safety factor is low, easily causes the event of hurting sb.'s feelings.
Utility model content
The purpose of this utility model is to provide a kind of swelling device of bucket elevator, to solve the swelling device of existing bucket elevator, exist swelling device easy to wear in operational process, overload capacity is poor, and expanding force is the wearing and tearing that constant force has increased device, the problem wasting energy.
For solving the problems of the technologies described above, technical solution adopted in the utility model is as follows:
A kind of swelling device of bucket elevator, it comprises pendant wheel, pendant wheel guide rail, bearing seat, tensioner regulating spring, adjusting bolt, between described pendant wheel adapter shaft and the baffle plate in bucket lifting machine drum body outside, be provided with sealed letter, the described bearing seat top at described pendant wheel adapter shaft two ends is respectively equipped with described tensioner regulating spring, the top of described tensioner regulating spring is provided with described adjusting bolt, and the outside of described tensioner regulating spring is provided with protective cover.
As further improvement of the utility model, in described sealed letter, be filled with sealer.
The beneficial effects of the utility model are: tensioner regulating spring, adjusting bolt are set on the outside of cylindrical shell, by tensioning regulating spring, to bearing seat, apply with expanding force, realize bucket elevator and changed expanding force size with the increase of bearing capacity, improved the overload quantity of bucket elevator; At tensioner regulating spring arranged outside protective cover, prevent that operation process medi-spring from flying out, and eliminated potential safety hazard; At pendant wheel, adapter shaft place sets up sealed letter, prevents from being raised material and leaks, and has reduced the wearing and tearing of the tightening device that rises.The novel service efficiency that improves bucket elevator of this use, has realized gig and according to the size of bearing capacity, expanding force has been regulated automatically, the difficulty of reduced the maintenance of bucket elevator pendant wheel, maintaining.
