Anti-chain dropping type bucket elevator
The utility model belongs to mine material vertical transport equipment technical field, relates in particular to a kind of anti-chain dropping type bucket elevator.
Bargh's bucket elevator commonly used is to utilize a series of hoppers that evenly are fixed on the driving component for no reason, the continuous conveyor equipment of vertical lifting material.Be divided into three kinds of loop chain, plate chain and belts.The transportation work principle of bucket elevator is: hopper is ladled out material from following storage, along with conveyer chain rises to the top, walks around the upset downwards of wheel back, top, in material impouring dump tank.The chain-drive bucket elevator mainly comprises actuating device, and the drive sprocket that is connected with actuating device with drive sprocket and revolution sprocket engagement bonded assembly ring chain, is interrupted the hopper that is arranged on the ring chain, chain stretching device and complete machine outer cover etc. simultaneously.But find to exist following shortcoming through long-term use: 1, because hoisting depth reaches the difference that material distributes in both sides more greatly, chain swinging is bigger, causes the revolution sprocket wheel of ring chain and bottom often to break away from.2, after the long-time running, chain link, chain are elongated, and the ring chain and the pitch error of revolution sprocket wheel are strengthened, and influence meshing quality, cause and take off the chain phenomenon.3, the race of revolution sprocket wheel is more shallow, makes chain be prone to scurry out from race, causes and takes off chain.Be easy to be extruded distortion and the consequence of taking off chain is a hopper, can't normally move.
Summary of the invention
The purpose of the utility model is to provide a kind of ring chain of avoiding to take off the anti-chain dropping type bucket elevator that chain takes place, reduces maintenance capacity
The purpose of the utility model realizes through following technical proposals:
The anti-chain dropping type bucket elevator of the utility model; Comprise actuating device, the dual drive wheel that is connected of actuating device therewith, the Crossed Circle chain that is connected with a joggle of dual drive wheel therewith respectively; Two gyrostats of being connected with a joggle of Crossed Circle chain therewith respectively; The base assembly and the one group of hopper that is connected with said Crossed Circle chain of this pair gyrostat are installed, are it is characterized in that described base assembly by sole plate, symmetry is fixed on the stand on this sole plate; The two ends difference is the horizontal rotating shaft of stand sliding block joint therewith; The axial limiting ring that is located at these horizontal rotating shaft both sides is respectively formed, and described pair of gyrostat is connected with the middle part of described horizontal rotating shaft, described stand by two vertical pillars of captiveing joint with described sole plate with respectively therewith two vertical pillars entablatrance and cross sill of captiveing joint form; Form the vertical chute with described horizontal rotating shaft sliding block joint between said two vertical pillars, described horizontal rotating shaft is between described entablatrance and cross sill.
Be equipped with the cannelure that is connected with a joggle with described Crossed Circle chain on described dual drive wheel and the two gyrostats, the degree of depth of this cannelure is 60 ㎜.
The advantage of the utility model:
The utility model adopts the connection mode that reaches axial limiting up and down to the horizontal rotating shaft of bottom, and horizontal rotating shaft can only be slided up and down in the actv. vertical space, avoids gyrostat swing rotation; Through strengthening the cannelure degree of depth of drive wheel and gyrostat and endless chain engagement usefulness, reduce the possibility that endless chain is jumped out groove, thereby stop to take off the generation of chain phenomenon, reduce equipment breakdown, reduce maintenance cost; The operating rate of raising equipment is stopped environmental pollution that causes because of the cleaning material and the generation that influences the healthy incident of worker.

The specific embodiment
The specific embodiment below in conjunction with description of drawings the utility model.
Like Fig. 1, shown in 2: the anti-chain dropping type bucket elevator of the utility model; Comprise actuating device 3; The dual drive wheel 2 that is connected of actuating device 3 therewith; The Crossed Circle chain 1 that is connected with a joggle of dual drive wheel therewith respectively, two gyrostats 9 of being connected with a joggle of Crossed Circle chain are therewith respectively installed the base assembly and the one group of hopper 10 that is connected with said Crossed Circle chain 1 of this pair gyrostat 9; It is characterized in that described base assembly is by sole plate 7; Symmetry is fixed on the stand on this sole plate 7, and the two ends difference is the horizontal rotating shaft 5 of stand sliding block joint therewith, is located at 8 compositions of axial limiting ring of these horizontal rotating shaft 5 both sides respectively; Described pair of gyrostat is connected with the middle part of described horizontal rotating shaft; Described stand by two vertical pillars 6 of captiveing joint with described sole plate 7 with respectively therewith two vertical pillars 6 entablatrance 4 and 11 of cross sills of captiveing joint form, form the vertical chute with described horizontal rotating shaft 5 sliding block joints between said two vertical pillars 6, described horizontal rotating shaft 5 is between described entablatrance 4 and cross sill 11.
Be equipped with the cannelure that is connected with a joggle with described Crossed Circle chain 1 on described dual drive wheel 2 and the two gyrostats 9, the depth H of this cannelure is 60 ㎜.
