Description

Double assembling and dismantling install standby
Technical field
The present invention relates to underground coal mine dismounts and mounts apparatus field, specially a kind of pair assembling and dismantling install standby, comprehensive for underground coal mine Adopt the decomposition and assembling of equipment.
Background technology
Coal mine fully-mechanized mining hydraulic support is most important equipment in coal mine fully-mechanized mining complete set of equipments, and hydraulic support is placed in fully mechanized mining work To form coal mining space in face of work, hydraulic support by highly pressurised liquid for active force complete the roof timbering of work surface, support reach, The work such as moving conveyor and Mined-out Area control.Hydraulic support has base, is connected with back timber, the front end hinge of back timber with column on base Forestope is connected to, rear end is hinged with caving shield.As hydraulic support volume is big, weight is big, and lane space is little, in installation process In, hydraulic support transports to down-hole after often first splitting into several parts, then part is transported to assembly chamber with flat car, portion Part constitutes integrated hydraulic support, the integrated hydraulic transporting bracket after assembling to installation site.
The hydraulic support of underground mine use plays a part of to support coal mine roof plate mostly at 10~30 tons or so.In its lower section It is the unit mined, general mine is smaller, hoisting power is limited, therefore the hydraulic support mined will decomposes after well again Assembling, will carry out schematic diagram illustrating before gug.At present, the method for the assembling that domestic each colliery carries out hydraulic support in down-hole generally makes With light instrument (pulling calabash well-pulley), there is following point:
1st, people must be operated under the heavy mail for being lifted by crane, and safety is compromised;
2nd, to big by the adjustment of hoist article, decomposition, assembly working difficulty;
3rd, labor efficiency is low, and labor strength is big, and input labour is more.
Mine hydraulic detachment installs the special equipment of the standby decomposition and assembling for being mine hydraulic support, and hydraulic support is mine work Make the support apparatus in face, hydraulic support enter well before be to decompose, assembled in cavern after entering well, after assembling, be transported to work Face, is also performed to decompose in down-hole cavern during gug.
Chinese utility model patent (the patent No.:91217179.0) a kind of underwell assembling platform of hydraulic support is disclosed, and this is special Profit adopts crown-block type structure, and tool larger space need to be accounted for during hoist article;In addition, single hook or double hook, lifting during hoist article Rope, reductor slideway etc. also occupy certain altitude (accumulative height is more than 1 meter);And, lifting rope corner individually can not rise or Drop, due to the restriction of down-hole height, need to be dug to down-hole assembling cavern deeply using the equipment, be difficult to realize in down-hole.
Chinese invention patent application (application number:201210233371.5) a kind of convenient boom hoisting of hydraulic support is disclosed, Including two I-shaped goosenecks, fixed tray is provided with the top at every I-shaped gooseneck two ends, in the bottom of I-shaped gooseneck It is provided with two symmetrical hangers;Advancing jack is additionally provided with, the telescopic section of advancing jack is downwards, very heavy elapsing The telescopic section termination on top is provided with gib head pin-and-hole, and suspension hook head is connected with gib head pin-and-hole;It is provided with the top of advancing jack Fixed seat, is provided with pin-and-hole in fixed seat, and that plays hanger wears pin through pin-and-hole, between the fixed ear of advancing jack and fixed seat Connected by steady brace.Using the structure for connecting advancing jack on I-shaped gooseneck, advancing jack is made as lifting Instrument, as different workpieces Heave Here profile is different, hangs and takes inconvenience.
In addition, currently for the larger fully-mechanized mining equipment of volume, weight, also suitably not dismounting and mounting equipment.
The content of the invention
It is an object of the invention to provide a kind of pair of assembling and dismantling install standby, the larger fully-mechanized mining equipment of existing volume, weight is solved The difficult problem such as it is difficult to dismount and mount.
The technical scheme is that:
A kind of pair of assembling and dismantling install standby, and double assembling and dismantling install that standby to be provided with moving cart, main lifting hydraulic cylinder, big footing, fixation little Car, lifting overcoat, lifting inner sleeve, crossbeam, concrete structure are as follows:
Four big footing are symmetrical arranged two-by-two, arrange elevating mechanism at the top of each big footing;Supporting big footing and lifting One group two-by-two of mechanism, is connected by crossbeam between the lifting inner sleeve of every group of elevating mechanism, is respectively provided with two movements little on crossbeam Car and two fixed dollies, moving cart setting corresponding with fixed dolly, moving cart and fixed dolly are respectively mounted sprocket wheel; Be respectively provided with two main lifting hydraulic cylinders in each elevating mechanism, one end of chain is connected with main lifting hydraulic cylinder, chain it is another One end passes through sprocket wheel and main lifting hook connects, forms double assembling and dismantling and installs standby;
Elevating mechanism includes lifting overcoat and lifting inner sleeve, and lifting inner sleeve is plugged in lifting overcoat, lifting inner sleeve and lifting Overcoat is slidably matched;Lifting overcoat setting location hole corresponding with lifting inner sleeve.
Described double assembling and dismantling install standby, and adjustment lifting inner sleeve rises or falls as needed, by lifting overcoat and liter Alignment pin is installed at the corresponding location hole of drop inner sleeve, makes lifting outer and relative localization in lifting.
Described double assembling and dismantling install standby, and auxiliary hook, auxiliary hook hydraulic cylinder are arranged between the main hook of each elevating mechanism By chain and auxiliary hook connects.
Described double assembling and dismantling install standby, and big footing side surface upper part is oppositely arranged walking ladder.
Advantages of the present invention and beneficial effect are:
1st, the mining pair of assembling and dismantling of the present invention install it is standby be suitable to the larger fully-mechanized mining equipment of volume, weight and dismount and mount, can be quick, safety The fully-mechanized mining equipment of down-hole is decomposed and assembled, operating system is adopted hydraulic control, instead of in the past artificial with chain block The conventional operation mode of operation, makes operating process mechanization, semi-brake, reduces labor strength, improves safety, realizes Quick, safe, reliable, efficient colliery management philosophy is the installation of fully-mechanized mining equipment and is removed there is provided extremely superior sheet Matter safe devices condition.
2nd, mining pair of assembling and dismantling of the present invention are installed for four main hooks are provided with, and realize and independent lifting operation at 4 points, are suitable for In decomposition and assembling of the underground coal mine to hydraulic support, other fully-mechanized mining equipments such as coal-winning machine, transporter, elevating conveyor are also applied for The loading-unloading vehicle of decomposition, assembling and loose mail.
3rd, the standby decomposition and assembling for meeting hydraulic support is installed in mining pair of assembling and dismantling of the present invention, realizes lifting force and lifting stroke Requirement, the lifting for completing hydraulic support decomposes and the decomposition of assembly working and other fully-mechanized mining equipments, assembling, loading-unloading vehicle work.
