Description
Technical field
The present invention relates to the manned device field, be specially a kind of soft start stepless speed regulating loop chain carrying traction overhead manned equipment.
Technical background
Overhead manned equipment (being commonly called as cableway) is a kind of less demanding to surface condition, can't implement at other transportation device under the situation of the personnel that transport or material, is to transport personnel or the indispensable transportation device of material.The characteristics of this transportation device are: it is little to take ground space, can realize the circuitous transportation continuously of aerial carrying traction, easily realize aerial, the dissimilar transportation device stereo staggered transport systems in ground, cost of investment is low, because of its exclusive feature, in the underworkings of mine, be used widely.Still there are many deficiencies but have the mine overhead manned equipment now, still adopt stall directly startup or stifled so shutdown as running startup and shutdown, cause whole drive system to impact greatly, accelerated to drive wearing and tearing and the driving system early failure of lining pad.Adopt hydrostatic drive can realize operating mechanism's soft start, infinite speed variation soft stop, but its driving efficiency is low, the fault rate height easily leaks, and contaminated environment is not the type of drive in user's ideal.Therefore the mine overhead manned equipment soft start stepless speed regulating technology solution that still requires study.
Steel rope is the main traction load member of existing overhead manned equipment, its type of drive is to rely on steel rope around the tensofriction transmission of drive wheel and tail tension wheel, because being subjected to the restriction of friction factor, its driving efficiency is low, load-carrying capacity is limited, especially level its complex structure that turns round, adaptive capacity is poor, and the overhead manned equipment regulation uses concurrent twist not have oily steel rope, and the Lang lay rope rigidity is big, the torque of bounce-back stress is big, the difficulty of pegging graft, poor reliability since bounce-back stress at short notice difficulty eliminate, therefore cause rope, the accident of translation frame happens occasionally, and brings hidden danger to safety in production.
The overhead manned equipment steel rope is to rely on friction to transmit to realize the carrying traction, for increasing friction factor, can only use no oily steel rope.Owing to be subjected to the restriction of usage condition, can't implement anti-oxidation measure.Especially the mine subsurface environment is more abominable, does not have that oily steel rope is easier to be damaged by corrosion, so service life is short, and maintain and replace steel rope work capacity is big, and influence is produced, and causes the use cost height.Rope clamping device is the carrying attaching parts of overhead manned equipment, for adapting to the needs of various varying environment operating modes, its drg of top (being on the reducer input shaft) that the safety arrestment of existing overhead manned equipment is arranged on driving system is the fluid power pusher brake, can only realize that stall impacts braking, in case the gear failure in the driving system, cause transmission terminal driving out of control, will jeopardize the person and device security.The holder rope sheave of existing overhead manned equipment because being subjected to the restriction of rope clamping device structure, can only use single semiaxis holder rope sheave structure, and owing to the tersional stress variation of steel rope and the discrepancy in elevation operation generation vibration that rope clamping device is connected with steel rope, the phenomenon of falling rope still exists.The kind form of rope clamping device is various, the movable rope clamping device in down-hole, mine is widely adopted, it is to adopt deadweight to hang to press connection mode that movable rope clamping device is connected with steel rope, utilize deadweight friction resistance moment to be driven running by steel rope, limited but transport the square gradient, sliding phenomenon happens occasionally, poor reliability, take uncomfortablely, safe operation is had a greatly reduced quality.
Summary of the invention
Big in order to overcome the system shock that has the overhead manned equipment existence now, deficiencies such as the wearing and tearing quickening of driving lining pad and driving system early failure, the present invention aims to provide a kind of soft start stepless speed regulating loop chain carrying traction overhead manned equipment, utilize planetary differential to have two-freedom, i.e. member input, the characteristic principles of two members output have realized the empty load of motor startup, have reduced when the motor load stall starts the attack time to electrical network.
