Brush 25 is shown in Figure 20 and 22 to guarantee having stable sealing effect.When industrial bar brush 25 has excessive abrasion, when sealing bad, answer and
When parking replace four boxes that industrial bar brush 25 makes.
Scheme two: as shown in figure 21, industrial bar brush frame to being pushed forward, pastes hairbrush by the thrust generated by four telescopic rods
Tightly on welding steel, make it that can prevent the dust in sandblasting sealing chamber 10 from leaking out and entering with fresh air outside
(under Wen's dust-removal cloth-bag dedusting, negative pressure will be generated in sandblasting sealing chamber 10).
Due to the walking of walking in a horizontal state trolley 1, hairbrush front end will generate friction with welding steel, and hairbrush will constantly be ground
Damage shortens, these abrasions shorten the thrust generated by four telescopic rods 28 and compensated automatically, with guarantee hairbrush front end with
Welding steel remains suitable pressure.
There are four the telescopic rods 28 of buffering, range 30mm, and working thrust (constant pressure) is 5-10N.
As shown in figs. 23 and 24, the sand leakage interface of remaining sand recyclable device 11 is located at the lower end surface of sandblasting sealing chamber, when high speed
After quartz sand hits weld seam and steel plate, a part of quartz sand has been hit into powder, and another part then also maintains a certain size.This
A little remaining sand particles have constant weight, will not be taken away by positive pressure siphon air-flow, under the effect of gravity, remaining sand particle will be along remaining sand
Recyclable device 11 is fallen into collection bag, and can be utilized again.
Wen's bag-type dust 8 is mainly made of air inlet mouth of pipe, siphon pipe and 208 terylene circle dust-removal cloth-bags.When nozzle is logical
After entering compressed air, under the action of high-speed flow, negative pressure will be generated at siphon pipe 81, by dust from sandblasting sealing chamber interior suction
Out, and through pipeline it is blown into dust-removal cloth-bag, the discharge of air permeable cloth bag, dust is fallen into bag after being intercepted by cloth bag, it is therefore prevented that dust
Pollution to environment.
As illustrated in figs. 25-27, the sandblasting sealing chamber 10 is equipped with device for recovering powder, preferably Wen's dust-extraction unit.
The device for recovering powder includes trunnion 105 and siphon pipe 81；One end of the trunnion 105 is compressed air inlet, the other end
For dust outlet；The trunnion 105 is connected to by siphon pipe 81 with the sandblasting sealing chamber 10, siphon pipe 81 and sandblasting sealing chamber

Another piece of battery backup, rotation work use.
Motor driven checking computations
It is as shown in figure 28 to calculate figure.
Walking in a horizontal state motor calculation:
See Figure 28
Equipment calculated weight be 35kg, remaining sand and dust weight 10kg,
∴ equipment weight G '=35+10=45kg
Consider the factors such as the impact of equipment operation, out-of-flatness, other resistances of track, takes dynamic load factor k=1.5.
∴ always calculates load G=kG '=1.5G '=1.5X45=67.5kg
G=70kg is taken to calculate
It is steel and steel rolling friction that principal and subordinate, which moves walking in a horizontal state wheel and walking in a horizontal state guide rail 4, and coefficient of friction is
μ1=0.15
It is the dynamic friction of rubber and rail between walking in a horizontal state support roller 12 and steel plate, coefficient of friction is
μ2=0.4-0.6, takes 0.6
Calculate the moment of friction F1, F2 (moment of resistance) of A, B two o'clock:
Normal pressure NA=NB=G/2
Walking in a horizontal state wheel total frictional force square MAB=μ1GX0.02=0.15X70kgX0.02m=2.1N-m.
Calculate the moment of friction F3, F4 (moment of resistance) of C, D two o'clock:
Normal pressure Σ M(ab)=0
GX (110-64)-Nx (480-20)=0
Nx=7kg
Walking in a horizontal state support 12 takes turns total frictional force square
MCD=μ2NxX0.035=0.6X7kgX0.035=1.47N-m
∴ total level walking resistance square is M '=MAB+MCD=2.1+1.47=3.57N-m
Walking in a horizontal state motor driving moment calculates
∵ M=9550P/n (N-m)
And P=0.06kw
N=4rpm
∴M60=9550X 0.06/4=143N-m
M60It is far longer than M '=3.57N-m.
It uses instead: square chest gear reduction unit 70GK500,30WZYT permanent magnet DC motor.
P=0.03kw
N=4rpm
It is considered as electric machine speed regulation, efficiency can be reduced, be calculated:
∴M30=(9550X 0.03X/4) X η=50.13N-m (taking efficiency eta=0.7)
M30Also it is much larger than M '=3.57N-m.
It uses instead again: square chest gear reduction unit 60GK500,20WZYT permanent magnet DC motor
P=0.02kw
N=4rpm
∴M20=(9550X 0.02X/4) X η=33.42N-m > M '=3.57N-m
∴ selects square chest gear reduction unit 60GK500,20WZYT permanent magnet DC motor that can fully meet horizontal drive requirement.
Vertical movable motor calculates, and sees calculating Figure 29.
Model specification identical with walking in a horizontal state motor is also used for convenience of manufacture installation and maintenance, vertical movable motor.
Its driving torque of ∴ is also
M20=(9550X 0.02X/4) X η=33.42N-m
The vertical movable motor of ∵ is the elevator rope roll by driving its front end, is promoted vertical walking dolly 7 with wirerope
Come up.
For ∴ under motor driven, the pulling force that wirerope can produce is P.
Mx=PX0.018
∴ P '=Mx/0.018=M20/ 0.018=33.42/0.018=1857N=185.7kg
Consider the factors such as the friction of vertically-guided part, the deflection of wirerope, multiplied by reduction coefficient 0.8, i.e.,
P=185.7X0.8=148.56kg
The pulling force that ∴ wirerope can produce is P=148kg；
The calculated weight of vertical walking dolly 7 is 14kg, remaining sand and dust weight 10kg, considers the other factors such as impact,
Taking dynamic load factor is 2.
Then load Gc=(14+10) X 2=48kg.
∵ P=148kg > Gc=48kg
∴ square chest gear reduction unit 60GK500,20WZYT permanent magnet DC motor fully meets vertical walking requirement.
