Embodiment
According to the requirement of coal conduit use condition and realization retractable, the shape and rapidoprint of coal conduit there has been
Particular/special requirement, to be made of three different cylindrical tubes of diameter, coal conduit diameter from the bottom to top is respectively concrete structure
700mm, 650mm, 600mm, each barrel lenght are 4m；On rapidoprint, coal conduit must have preferable wearability
Can, cylinder selects the 16Mn steel plates processing of δ 4mm thickness, to improve its service life.
According to the operation principle of coal conduit, the steel wire rope of driving device traction is only connect with 700mm cylinders, is driven
700mm cylinders move up and down, and the movement of other two cylinder must be suitable according to design installation by the power source of 700mm cylinders
Sequence, the cylinder of 600mm are mounted on topmost, and from top to bottom barrel diameter is sequentially increased, as a result, according between three cylinders
Mutual installation site relationship and motion principle need to be enclosed inside or outside each cylinder along cylinder circumference soldering one and be limited respectively
Position ring realizes the locking and linkage between three cylinders by spacing ring, and spacing ring is using the round steel of 16mm on cylinder
Mouthful or lower mouth 100mm at position welded, specific requirement is：The mouth outer circle welded limiting ring under the cylinder of 600mm；By
Between the cylinder of 650mm is mounted on other two cylinder, for connecting two cylinders up and down, on it mouth inside and outside circle, lower mouth
Spacing ring is respectively welded in outer circle；Spacing ring is respectively welded, in cylinder lower part symmetric position difference in 700mm cylinders inner circle suitable for reading
Weld a steel wire rope connection ring.
Driving device must satisfy coal conduit realization stretch, the movement of contracting both direction, meanwhile, to ensure that coal conduit stretches work(
Can it is safe and reliable, the stretching speed of control is unsuitable too fast, according to this requirement, selects the drawing hoist that speed is 0.12m/s
As power source, power switch uses QBZ-80N vacuum electromagnetic starters；Meanwhile during to ensure that rope traction cylinder is flexible,
Cylinder uniform force need to be transformed drawing hoist, and partition board is enclosed in the center line circumference soldering one of drawing hoist roller width, and
Card cord hole is processed on partition board, roller one is made to become two, is i.e. a roller draws two steel wire ropes and is symmetrically connected to 700mm simultaneously
In the steel wire rope connection ring of body, ensure cylinder uniform force, Telescopic is stablized.
To prevent operating personnel during operation, since artificial origin occurs stopping not in time, coal conduit being caused to be promoted
, there is breaking steel wire rope in volume, and coal conduit falls situation, and design is mounted with limiting and protecting device, and concrete scheme is：In topmost
One limitation travel switch is installed, while it is true that limitation travel switch is sealed in QBZ-80N at 600mm cylinders downward 300mm suitable for reading
In the control loop that empty electromagnetic starter switch control coal conduit above carries, limiting row is touched when coal conduit is promoted to certain altitude
During Cheng Kaiguan, control power supply automatically powers off, and coal conduit stopping action effectively solving and promotes pulleying phenomenon.
Due to 12 meters of coal conduit overall length, for prevent its influenced to occur to wave by coal stream movement and strong wind weather, shaking amplitude
Excessive phenomenon, design are mounted with the anti-beat protective device of frame-type, and concrete scheme is：Using 120 channel steels weld one 900 ×
The square frame of 900mm fixes one end of a 11# steel I-beam, work on the cement beam of the oblique corridor building vertical column of belt
The other end of word girder steel welds together with square frame, when coal breakage barrel stroke all stretches out, the anti-beat protection of frame-type
Device ensures 700mm cylinders under any circumstance, beat amount be no more than 200mm, it is ensured that coal conduit it is safe to use.
Since the installation site of coal conduit is apart from about more than 20 rice of ground, need to combine field condition and use when mounted
It is required that considering many factors, the fixation of wherein topmost 600mm cylinders is particularly important, only solves this well and asks
Topic, could fundamentally ensure the safe handling of coal conduit.With reference to my company's field condition, the fixation of topmost 600mm cylinders
By the use of two 8 meters long of 11# steel I-beams as fixed supporting beam, by the crossbeam on the cement post of the oblique corridor building of belt
By steel I-beam fixation, and add reinforcement support of the diagonal brace as two 11# steel I-beams in lower part, outside 600mm cylinders
A supporting plate is welded every 90 ° on round week, supporting plate seat is on steel I-beam and integrally welded with steel I-beam.
