Description
Technical field
The utility model relates to a kind of coal mining equipments, in particular to a kind of hydraulic support lateral thruster.
Background technique
Hydraulic support is the key equipment of comprehensive mechanical coal mining equipment, and function is effectively to support and control working face
Top plate guarantees the safety work space of worker and equipment, improves 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
It mainly include 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 bracket is stretched within the scope of one fixed width and has gear cash sealing, guiding of trying to stop people from fighting each other, tune
Whole bracket posture, prevents down the effect of frame.
Traditional lateral thruster generally pushes away jack by beam body, side guard plate, side and spring, guide rod and attachment form, when use
It is required according to working face direction, side is fixed, side activity.When installation, side guard plate is installed after connecting with guide rod from two sides, and side pushes away
Jack is packed into inside beam body by the hole in 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 pin shaft, and when use removes active side pin shaft
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 pin shaft, remove cylinder bottom and
The connection pin shaft 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 large labor intensity, production efficiency is low, there is peace
The disadvantages of full hidden danger.
