Description
Technical field
The present invention relates to a kind of processing of dust or technical field of coal mine, and in particular to a kind of pumping dirt hose and walking mechanism are same
Walk draw off gear.
Background technique
Negative-pressure ward dust is generally used in explosive dust processing technology field, then by pipeline transportation, into removing
Dirt device, this kind of pipeline can deposit a large amount of dust in tube wall after using the time longer, and be attached on tube wall, what these were deposited
Dust is easy to secondary fly-up, increases explosion probability, is very big security risk.
There is special pipeline dust cleaning machine people at present, generally included dust catcher and ash bucket cause entire mechanism body
Product is very big and power demand is high, if be used in explosion environment, there is very big security risk.If walking mechanism can set suction
Standby pumping dirt hose brings pipeline into aspirate the explosive dust of tube wall attachment, and dust catcher is located at outside pipeline, can substantially reduce
The volume of walking mechanism, and safety is improved, but be mostly wired hose due to taking out dirt hose, heavier and longer, vehicle with walking machine
Dirt hose is taken out when structure is walked in pipeline to cause resistance with pipe friction, cause deashing robot additionally to increase very big dynamic
Power, and walk slowly, in addition when robot retracts, hose is easy to knot or fall off even to be wound or folds in the duct hose
Robot is caused not retract normally, hose itself can also be damaged, and entire automatic ash removing mechanism is caused to be paralysed.
Summary of the invention
It is an object of the invention to take out dirt pipeline dust cleaning machine people for current explosive dust to carry dust suction
Device and dust accumulation bucket security risk are big, volume is big or dragging pumping dirt hose enters the hose that pipeline deashing occurs and is easy to fall off, damages
The problem that bad even winding walking mechanism causes robot that can not retract provides a kind of pumping dirt hose folding and unfolding synchronous with walking mechanism
Device.
In order to achieve the above-mentioned object of the invention, the present invention provides following technical schemes:
Take out dirt hose and walking mechanism synchronous reeling and releasing device, including traction rope, first gear and second gear, the first gear
Cooperate with the second gear, first pulley, the traction rope and the first pulley are coaxially fixed in the first gear
Cooperate, is coaxially fixed with second pulley in the second gear, the wheel face of the second pulley there are the imploded arcs isometrical with hose
Face, Rc1/Rc2=Rh1/Rh2, wherein Rc1 is the working radius of first gear, and Rc2 is the working radius of second gear, and Rh1 is
The working radius of first pulley, Rh2 are the working radiuses of second pulley.
Preferably, the pumping dirt hose and walking mechanism synchronous reeling and releasing device further include third pulley, the third is sliding
Wheel and second pulley cooperation, which are used to press, takes out dirt hose, Rh3=Rh2, Rh3It is the working radius of third pulley.More there is choosing,
The second pulley and third pulley cooperation radian are equal with wired hose circumference arc, increase the frictional force of pressing simultaneously
And power prolongs the dispersion of hose whole circumference, guarantees that hose will not skid.
Preferably, Rc1=Rc2, Rh1=Rh2, thus structure is simple.
Preferably, the indent wheel face of the third pulley and the indent wheel face of the second pulley cooperate to accommodate pumping dirt
Hose, the third pulley and second pulley distance are suitable, which makes the third pulley and described second
After pulley cooperation is for pressing pumping dirt hose, the third pulley and the second pulley are not contacted, and thereby, it is possible to reduce to skid
A possibility that, guarantee to move synchronously.
Compared with prior art, beneficial effects of the present invention: traction rope is connected with walking mechanism, the movement of traction rope
Speed is identical as the movement velocity of walking mechanism, and since first gear and second gear engage, first pulley and second gear are same
Axis is fixed, and second gear and second pulley are coaxially fixed, and Rc1/Rc2=Rh1/Rh2, as a result, in second pulley and third pulley
After taking out the pressing cooperation of dirt hose, first pulley is driven by gear makes pumping dirt soft with the pressing frictional force of the second third pulley
Pipe movement to realize that pumping dirt hose is identical as the speed of walking mechanism (connecting everywhere non-slip), and can guarantee that pumping dirt is soft
Pipe moves synchronously under the action of frictional force with walking mechanism, avoids because the power of pullling of walking mechanism makes pumping dirt hose fall off
Or damage the problem of, hose also frictional force effect under synchronized callback, will not knot, wind walking mechanism, will not be to walking
Mechanism causes walking resistance, and compared to other sweeping robots, the application is suitable for the cleaning of dust of exploding, and safety is higher.

Specific embodiment
Below with reference to test example and specific embodiment, the present invention is described in further detail.But this should not be understood
It is all that this is belonged to based on the technology that the content of present invention is realized for the scope of the above subject matter of the present invention is limited to the following embodiments
The range of invention.
Referring to Fig. 1-5, takes out dirt hose and walking mechanism synchronous reeling and releasing device includes traction rope 140, first gear 111 and the
Two gears 121, first gear 111 and second gear 121 cooperate, and are coaxially fixed with first pulley 112 in first gear 111, lead
Messenger 140 and first pulley 112 cooperate, and are coaxially fixed with second pulley 122, the wheel face of second pulley 122 in second gear 121
There is the arc concave shape isometrical with hose, Rc1/Rc2=Rh1/Rh2, wherein Rc1 is the working radius of first gear 111, and Rc2 is
The working radius of two gears 121, Rh1 are the working radiuses of first pulley 112, and Rh2 is the working radius of second pulley 122.It takes out
Dirt hose and walking mechanism synchronous reeling and releasing device further include third pulley 123, and third pulley 123 and second pulley 122, which are matched, to be shared
Take out dirt hose 130 in pressing, particularly, second and third pulley 123 have an inner concave arc surface isometrical with hose, Rh3=Rh2,
Rh3 is the working radius of third pulley 123, Rc1=Rc2, Rh1=Rh2, in this way, the application synchronous reeling and releasing device is at work, due to
First gear 111 and second gear 121 engage, and first pulley 112 and second gear 121 are coaxially fixed, second gear 121 and the
Two pulleys 122 are coaxially fixed, and Rc1/Rc2=Rh1/Rh2, as a result, in second pulley 122 and after taking out the pressing cooperation of dirt hose 130, the
Two gears 121 make to take out the movement of dirt hose 130 by frictional force, so that it is identical as the speed of walking mechanism 200 to take out dirt hose 130
Connect everywhere it is non-slip, so as to guarantee take out dirt hose 130 moved synchronously under the action of frictional force with walking mechanism 200,
It avoids because the power of pullling of walking mechanism 200 makes pumping dirt hose 130 fall off, damages and even expend asking for the very big power of mechanism
