Downside curvature is small；314 end face of slide plate is provided with and the protrusion 321 that matches on the downside of shrinkage pool 320.When 314 end face of slide plate
When being detached from 21 inner wall of reel, protrusion 321 can slide into and skid off shrinkage pool 320, since 320 upside curvature of shrinkage pool is smaller than downside curvature,
Therefore the disengaging shrinkage pool 320 that 321 meeting of protrusion is more smooth, 314 end face of slide plate is detached from 21 inner wall of reel can more quickly；When slide plate 314
When pulling to sliding slot 312 by the restoring force of No. four springs 313, due to 320 upside curvature of shrinkage pool than downside curvature it is small, protrusion 321 into
It will receive the biggish frictional force of shrinkage pool 320 when shrinkage pool 320 out, keep the braking of reel 21 rapider.
As one such embodiment, air flue 322 is equipped in the slide plate 314；Described 322 one end of air flue and sliding slot
312 connections, 322 other end of air flue are connected to protrusion 321.When slide plate 314 is driven by centrifugal force to which 314 end face of slide plate is detached from
When 21 inner wall of reel, the seal chamber that slide plate 314 is formed with sliding slot 312 will become larger, so that negative pressure is generated in seal chamber, protrusion
321 can be compressed by air flue 322 by negative pressure, and protrusion 321 shrinks to keep disengaging 21 inner wall of reel of slide plate 314 more smooth；When
When slide plate 314 can pull to sliding slot 312 by the restoring force of No. four springs 313, the seal chamber that slide plate 314 and sliding slot 312 are formed will
Become smaller, to generate positive pressure in seal chamber, protrusion 321 can be by air flue 322 by positive compression swelling, and 321 expansion of protrusion is to make to slide
The frictional force of 314 brake drum of plate, 21 inner wall is bigger, and the torsion that the frictional force of generation is generated with motor shaft is cancelled out each other, and can drop
Low motor shaft torque improves motor shaft service life, and slide plate 314 stops the volume after rear projection 321 is located in shrinkage pool 320 will
Reach maximum, ensure that slide plate 314 to the self-locking of reel 21.
The application primarily to reduce motor brake load and reduce motor shaft torque, it is interior when making motor braking
Portion generates reverse friction power, on the one hand can reduce motor braking load, on the other hand can reduce motor shaft torque, raising makes
With the service life, motor speed is faster, and braking motor axis torque is bigger, seriously affects motor service life.
Motor shaft is acted on by an output torque, while his radial force and tangential force are also given by three planetary gears,
Since three planetary gears are uniformly distributed, therefore tangential force suffered by motor shaft and radial force offset, and are only acted on by torque.
It is calculated by torsion strength condition, calculation formula are as follows:
T=TIt turns round-u(N/mm)
In formula: τT--- shearing stress in torsion power (MPa)；
T --- torque suffered by axis reality (Nmm),
TIt turns round--- normal suffered torque (Nmm) of axis under the influence of zerofriction force,
U --- frictional force (N/mm) caused by braking；
WT--- the Torsion Section coefficient (mm of axis3),
The application improves electric block model CD1 type electric block, the Torsion Section coefficient of axis
[τT] --- the allowable shear stress of axis is tabled look-up according to selected materials, [τT]=35~55MPa
Can be seen that by the motor shaft allowable shear stress line chart under different rotating speeds, improved CD1 type electric block with not
For improved CD1 type electric block under same rotational speed, motor shaft allowable shear stress is smaller, and the service life of motor shaft is higher.
As one such embodiment, cynapse 323 is provided on the downside of the slide plate 314；21 inner wall of reel is solid
It is connected with sounding tube 324；324 surface of sounding tube is provided with the hole 325 to match with cynapse 323.When reel 21 stops
After rotation, the cynapse 323 of 314 downside of slide plate can contact the hole 325 of sounding tube 324, if the weight of lifting surprisingly falls,
Cynapse 323 can gradually pass in and out hole 325 when reel 21 rotates, to make a sound, personnel can judge that reel 21 is according to sounding
No unintentional rotation, to avoid personnel from not noticing that the unexpected of weight falls, to cause accidental wound to personnel or workpiece
Evil.
When work, when electric block needs to transport object, start operating mechanism speed reducer 7,7 band of operating mechanism speed reducer
Motor car wheel 6 is run on the rail 5, and wheel 6 drives rack 4 mobile；When electric block reaches above object, machine out of service
Structure speed reducer 7, at this point, starting lifting mechanism motor 3, the air-gap field of lifting mechanism motor 3 generates axial magnetic pull pressure
Contracting and No. three springs 34 for stretching 36 two sides of rotor, drive moving axis 310 to move in aperture 311 so that rotor 36 moves right,
The aperture 311 of motor shaft 32 is spliced by about 32 two halves of motor shaft, and moving axis 310 drives support ring 38 to move right, thus
Disengage the brake hoop 39 on fan braked wheel 37 and motor cabinet 33, motor shaft 32 can be freely rotated；It is axial when power-off
Magnetic pull disappears, and rotor 36 generates axial movement under the thrust of No. three springs 34 and pulling force, and it is dynamic that rotor 36 is moved to the left drive
Axis 310 moves in aperture 311, and moving axis 310 drives support ring 38 to be moved to the left, so that fan braked wheel 37 be made to compress braking
Ring 39 generates frictional force, lifting mechanism motor 3 is forced to stall and pinion rotor 36 rapidly, under the weight to prevent lifting
It falls, ensures safety；And when motor shaft 32 rotates, motor shaft 32 drives rubbercushioned sleeve bearing coupling 31 to rotate, slide plate 314
Can be by centrifugal force whipping outward, so that 314 end face of slide plate will be disengaged from 21 inner wall of reel, slide plate 314 rubs to 21 inner wall of reel
Wiping power will disappear, and after motor shaft 32 stops operating, slide plate 314 can pull to sliding slot 312 by the restoring force of No. four springs 313, thus
314 end face of slide plate will contact 21 inner wall of reel, and slide plate 314 can generate frictional force to 21 inner wall of reel, further prevent lifting
Weight-drop ensures safety；No.1 input shaft 110 is driven to rotate when rubbercushioned sleeve bearing coupling 31 rotates, No.1 input shaft
110 rotation drive box couplings 19 rotate, fixed board 113 drive movable plate 115 rotate, movable plate 115 can by centrifugal force to output method
Blue 17 whippings, the confined space that fixed board 113, movable plate 115 and No.1 chamber 112 are formed, which can become larger, generates negative pressure, and No.1 chamber 112 is logical
Piping 119 drives the nog plate 117 in No. two chambers 116 to be detached from box coupling 19, and box coupling 19 can be freely rotated, when
After box coupling 19 stops operating, nog plate 117 can generate frictional force to box coupling 19, further prevent lifting
Weight-drop ensures safety；Fan braked wheel 37 and motor cabinet can be made using moving axis 310, aperture 311 and support ring 38
When brake hoop 39 on 33 disengages, motor shaft 32 is not moved, and guarantee motor shaft 32 is matched with rubbercushioned sleeve bearing coupling 31
It closes, enhances the transmission intensity and rigidity of Hoist Mechanism 1 Yu lifting mechanism motor 3, enhance the peace of electric block
Quan Xing；When rubbercushioned sleeve bearing coupling 31 is driven to rotate by motor shaft 32, slide plate 314 can be by centrifugal force whipping, thus sliding
314 end face of plate is detached from 21 inner wall of reel, and after rubbercushioned sleeve bearing coupling 31 stops operating, 314 end face of slide plate can be in reel 21
Wall generates frictional force, slide plate 314 ensure that motor shaft 32 to the self-locking of reel 21, reel 21 and lifting mechanism motor 3 it
Between increase one and ensure again, after avoiding Hoist Mechanism 1 from damaging, the weight of lifting surprisingly falls；Fixed board 113, movable plate
115 and nog plate 117 increase lifting mechanism motor 3 to the self-locking of Hoist Mechanism 1, prevent the weight of lifting unexpected
When whereabouts, torsion of the Hoist Mechanism 1 to lifting mechanism motor 3 protects lifting mechanism motor 3.
