Description
Technical field
The present invention relates to a kind of coal deep-well lifting system, especially a kind of more steel wire rope coals of split type floating head sheave group
Deep-well lifting system belongs to underground coal mine transportation art.
Background technology
Hoisting container is the critical equipment of underground coal mine conveying coal and personnel, it is responsible for coal, personnel, equipment and object
The promotion task of material.There are many influence factor of lifting system, and in km deep-well, hoisting container is up to 16m/s, load-carrying with speed
For amount up to loading and unloading material under 45 tons of operating mode, more steel wire ropes connect with hoisting container produce bullet under varying load again by force herein
Property variable elongation differ problem, tension difference is larger between causing each steel wire rope, needs more frequent tune rope operation, once adjust rope inclined
Difference is excessive, then easily causes hoisting container oblique attitude, and then lead to card tank, rope service-life is caused to decline to a great extent.Therefore, big ton
More steel wire rope tensions of position high speed hoisting container are coordinated the technical barriers such as performance and have been highlighted.
Head sheave group is its key equipment, for adjusting tension difference between more steel wire ropes.The operation principle ratio of integral type head sheave group
It is relatively simple, exactly one end of more steel wire ropes is fixed and is wrapped on the roller of elevator, the head sheave at the top of other end pile warp
Group connection hoisting container.The use scope of integral type head sheave group elevator is restricted under the conditions of km deep-well, this is because
In the big terminal load of deep-well, in order to undertake the weight of terminal load and steel cable itself, steel cable needs often to adjust tension.
Invention content
In order to overcome the above-mentioned deficiency of the prior art, the present invention to provide a kind of split type more steel wire rope coals of floating head sheave group
Deep-well lifting system, can under operating mode out of control more steel wire rope tension active tolerant controls, rigid cord tension is monitored in real time, is assisted
Regulation and control system reduces and adjusts rope operations number, improves rope service-life.
The present invention solve its technical problem the technical solution adopted is that：It is described including hoisting container and floating head sheave group
Floating head sheave group includes that upper split type floating head sheave group split type floating head sheave group, the two under actively adjust liquid with each respectively
Cylinder pressure connects；Hoisting container is two, including upper hoisting container and lower hoisting container, and passive adjust is equipped with above hoisting container
Suspension hydraulic cylinder, steel wire rope both ends are connect by passively adjusting suspension hydraulic cylinder with hoisting container, pass through one among steel wire rope
Main shaft device, main shaft device are located at the side-lower of floating head sheave group, and upper split type floating head sheave group is set to main shaft device under
Between hoisting container, under split type floating head sheave group be arranged between main shaft device and upper hoisting container；Upper hoisting container is under
It is connected by tail rope between the lower end of hoisting container；It further include a set of control system.
Compared with prior art, a kind of split type more steel wire rope coal deep-well lifting systems of floating head sheave group of the invention are
By traditional more steel wire rope coal deep-well lifting systems of integral type head sheave group transform as can free floating split type head sheave group it is more
Steel wire rope coal deep-well lifting system, is passively adjusted using hanging oil cylinder and hydraulic cylinder actively adjusts floating head sheave, is actively adjusted
The upper split type floating head sheave group of hydraulic cylinder control, under split type floating head sheave group moved accordingly, adjusting steel wire rope tension,
Can be with independently working to the head sheave of each head sheave group, when elevator works, the every steel wire rope that subject pulling force can be independent
It adjusts, realizes more steel wire rope tension active tolerant controls under operating mode out of control, solve large-tonnage hoisting container high-speed cruising
Problem out of control, the steel wire rope tension for realizing coal mine deep well hoisting container monitor, coordinate control in real time, ensure that steel wire rope is certain
Bearing capacity and service life.
Description of the drawings
Present invention will be further explained below with reference to the attached drawings and examples.
Fig. 1 is the structure drawing of device of the embodiment of the present invention.
In figure, 1, it is passive adjust suspension hydraulic cylinder, 2, actively adjust hydraulic cylinder, 3, upper split type floating head sheave group, 4, under
Split type floating head sheave group, 5, steel wire rope, 6, main shaft device, 7-1, upper hoisting container, 7-2, lower hoisting container, 8, tail rope.
Specific implementation mode
In order to make the object, technical scheme and advantages of the embodiment of the invention clearer, below in conjunction with the embodiment of the present invention
In attached drawing, technical scheme in the embodiment of the invention is clearly and completely described, it is clear that described embodiment is
A part of the embodiment of the present invention, instead of all the embodiments.Based on the embodiments of the present invention, ordinary skill people
The every other embodiment that member is obtained without making creative work, belongs to protection scope of the present invention.
In the embodiment shown in fig. 1, the more steel wire rope coal deep-well lifting systems of a kind of split type floating head sheave group, including eight
A passive adjusting suspension hydraulic cylinder 1, eight actively adjust hydraulic cylinder 2, a upper split type floating head sheave group 3, seperated under one
Formula floating head sheave group 4, four steel wire ropes 5, a main shaft device 6, two hoisting containers 7, two tail ropes 8 and a set of control system
System.The hoisting container is using four rope pulling modes, for conveying coal, personnel, equipment and material.Described is upper split type
Floating head sheave group 3 is made of four independent floating head sheaves.There are four independent floatings for split type floating head sheave group 4 under described
Head sheave forms.The passive adjusting suspension hydraulic cylinder 1, actively adjusting hydraulic cylinder 2, to be used for adjusting lineoutofservice signal pull poor, with adjustment
Hoisting container posture.For the passive suspension hydraulic cylinder 1 that adjusts above hoisting container 7, upper split type floating head sheave group 3 is split type under
Floating head sheave group 4 actively adjusts hydraulic cylinder 2 with 4 respectively and connect, and when promoting machine operation, actively adjusts and divides in the control of hydraulic cylinder 2
Body formula floating head sheave group 3, under split type floating head sheave group 4 moved accordingly, adjust 5 tension of steel wire rope, 5 both ends of steel wire rope
It is connect with hoisting container 7 by passively adjusting suspension hydraulic cylinder 1.5 both ends of steel wire rope are respectively by passively adjusting suspension hydraulic cylinder 1
It is connect with hoisting container 7, control hoisting container vertical movement, main shaft device 6 in 5 intermediate pile warp of steel wire rope, 6 conduct of main shaft device
Power plant drives 5 operation of steel wire rope, and split type floating head sheave group 3 is connect with lower hoisting container 7-2 in overlap pile warp, under go out
Restrict pile warp under split type floating head sheave group 4 be that upper hoisting container 7-1 is connect, upper split type floating head sheave group 3 is split type under
Prevailing tensions regulation device of the floating head sheave group 4 as whole system, it is poor for dynamic regulation steel wire rope tension.It is upper split type floating
Dynamic head sheave group 3 and under split type floating head sheave group 4 respectively with actively adjust hydraulic cylinder 2 and connect.The both ends of tail rope 8 respectively with promotion
The lower part of container 7 mounts.
