Description
Technical field
The present invention relates to a kind of coal mining equipments, in particular to a kind of hydraulic support lateral thruster.
Background technology
Hydraulic support is the key equipment of comprehensive mechanical coal mining equipment, and function is effectively to support and control working face
Top plate ensures the safety work space of worker and equipment, is improved to Safety of Coal Mine Production, working face layout, improves working face labor
Fatigue resistance and improving labor efficiency is of great significance.
Hydraulic support is made of load assembly, hydraulic cylinder, hydraulic control system and other auxiliary devices.Load assembly
Include mainly the welding structural elements such as top beam, caving shield, pedestal, front and rear connecting rods, top beam directly and top plate contact, transmits support force
And play action retaining the top；Pedestal directly transmits support force with contacts baseplate and is used for the other components of rest；Caving shield connects top beam, bottom
Seat and connecting rod bear support level power and are caving balkstone pressure, prevent erecting dense individual props spoil from entering internal stent.
Bilateral activity lateral thruster is set at hydraulic support top beam, caving shield or tail boom, according to working face side when use
To requiring, side is fixed, side activity, so that holder is stretched within the scope of one fixed width and has the sealing of gear cash, guiding of trying to stop people from fighting each other, tune
Whole holder posture, prevents down the effect of frame.
Traditional lateral thruster generally pushes away jack and spring by beam body, side guard plate, side, guide rod and attachment forms, when use
It is required according to working face direction, side is fixed, side activity.When installation, side guard plate is installed after being connect with guide rod from both sides, and side pushes away
Jack is packed by the hole in beam body inside beam body, and cylinder bottom is connect with fixed side guard plate direction arm, piston rod and affixed side
The connection of backplate direction guide rod, guide rod and beam body are fixed finally by axis pin, and when use removes active side axis pin
The release to movable side protection plate can be realized, retract control.
Since beam body and side push away jack structure limitation, when the change of working face direction, need accordingly to convert movable side protection plate
Support direction, side pushed away into jack first and is retracted to least limit length, install active side guide rod axis pin, remove cylinder bottom and
The connection axis pin of piston rod；Then side is pushed away into jack and splits out beam body and turns 180 ° and put in back in beam body, realize transformation active side
The support direction of backplate.
When traditional lateral thruster transformation movable side protection plate support direction, there are labor intensity greatly, low production efficiency, there is peace
The shortcomings of full hidden danger.

Structure reduces side ejection cylinder body and enters the height dimension in top beam and caving shield to greatest extent.Secondly, side is pushed away into jack cylinder bottom
Position feed liquor nozzle is led to by fluid-through tube near cylinder mouth feed liquor nozzle so that when cylinder bottom enters beam body conduit as mobile position, with side
The high-pressure rubber pipe for pushing away jack connection is not in contact with beam body, and Pipe Cutting phenomenon is avoided to occur.
Hydraulic support lateral thruster of the present invention carries out innovative design to hydraulic support beam body, and respective side pushes away very heavy top plate type
Gap is arranged in fluid-through tube position, it is ensured that and side pushes away jack cylinder body and can free in and out in top beam and caving shield and not interfere,
Ensure beam body intensity to greatest extent simultaneously.
Hydraulic support lateral thruster of the present invention breaks conventional hydraulic holder maintenance mode, and top beam, caving shield side guard plate is made to fall
Face direction work living becomes to be simple and efficient, by the installation site for converting guide rod axis pin, you can realization does not dismantle side and pushes away jack
Hydraulic support is examined to solve the problems, such as that traditional lateral thruster structure exists to convert movable side protection plate support direction
It repaiies during operating personnel falls face direction work living from heavy side guard plate and frees；Down-hole combined mining working can also be according to need
It wants, very easily the work of falling side guard plate face direction, adopting face hydraulic support failure for processing has larger help, with conventional hydraulic holder
Side guard plate compare by face direction living, and decades of times can be improved in efficiency, and economic benefit is very huge, has very strong promotional value.
When Novel free dismounts lateral thruster transformation movable side protection plate support direction, it is only necessary to side be pushed away jack and be retracted to minimum
Then limiting length, installation activity side guide rod axis pin remove affixed side guide rod axis pin, the side of innovative design pushes away jack and passes through beam
Gap on body enters inside beam body, by side push away jack by piston rod move form be converted into cylinder move form, you can realize become
Change movable side protection plate support direction.
