Description
Technical field
Mining machinery technical field is the utility model is related to, more particularly to a kind of four-degree-of-freedom for bearing multi-direction power is simultaneously
Join hydraulic support.
Background technology
Comprehensive mechanized coal mining equipment is by hydraulic support, coal-winning machine and transport establishment into hydraulic support is as comprehensive mechanical coal mining
Work capital equipment, and one-time investment accounts for more than the 70% of fully mechanized mining equipment total fund, is that fully-mechanized mining working realizes safe efficient life
The key of production.The top of hydraulic support, bottom plate must adapt to working face in the pit coal seam environment, and the operation of safety is provided for operating personnel
Space, also effective power source is provided to adopt, transporting equipment, determine the normal fltting speed of Harvesting equipment.Therefore, hydraulic support
It is the key equipment that can fully-mechanized mining working realize high-yield and high-efficiency success or failure.
During fully mechanized mining operation, hydraulic support is distributed across on whole coal-face, is realized support, is cut top, moves and push away certainly
The process such as slip, its comprehensive mechanization with high-power coal cutter, the flexible flightconveyor composition stope of large conveying quantity
Equipment.During fully mechanized mining operation, the key factor of hydraulic support or high seam Longwall top coal caving technology success or failure.Now widely used liquid
Pressure support grows up on the basis of all in the sixties in last century, people from former Soviet Union is related to double leval jib hydraulic support.But due to coal seam
The reason for inclination angle and geological structure, top plate certainly exist cross component force to the pressure of hydraulic support.And existing double leval jib type branch
Frame does not bear the ability of side force, and side force then passes to linkage by caving shield, and this is to cause down frame and support
The basic reason of mechanism damage, thus principle defect be present in existing link type hydraulic support.Because lanar four rod mechanism
Only there is 1 free degree, the free degree of 2 parallel lanar four rod mechanisms is -1, belongs to indeterminate mechanism, causes hydraulic pressure branch
Frame stability is poor, and bearing height also receives limitation.And China Mine Geological is complicated, in actual applications due to top plate not
The change of planarization and seam inclination, larger additional load can be produced, cause caving shield damage, the great peace such as frame and downslide of falling
Full accident.
Since double leval jib type hydraulic support utility model over more than 50 years, each producing coal country of the world is all in use
To having carried out substantial amounts of research and improvement based on double leval jib type hydraulic support.But to the branch based on double leval jib hydraulic support
Support stability, to the problem of adaptability of top plate and the Controllability of support are not structure designs, but be based on double leval jib liquid
Caused by principle defect being present in pressure bracket institution.And parallel institution has that the rigidity of structure is big, bearing capacity is strong, inertia is small, fixed
The features such as position and kinematic accuracy are high, parallel institution turn into the optimum supporting mechanism of mine hydraulic bracket, its high stability and right
The most complete adaptability of movement of roof, and mechanical property optimal in self structure determine parallel hydraulic support bearing height
Greatly, high stability, it is in light weight, elapse fast superiority.In view of existing be based on principle defect existing for double leval jib hydraulic support,
The sub- penetrating judgment of bandit of Institutes Of Technology Of Taiyuan is awarded and its Master degree candidate defend into etc. propose by parallel institution be applied to hydraulic support in, i.e.,
Design it is a kind of based on the new type hydraulic bearer of parallel institution with solve double leval jib type hydraulic support principle imperfect tape come a system
Row problem, early stage are all based on the six-freedom parallel liquid of 6-SPS parallel institutions on the design and research of parallel hydraulic support
Press support, and underground coal mine working face actual use hydraulic support and do not need six-freedom degree.The excessive free degree is not only
So that the complicated of hydraulic support, difficulty of processing improve, machining accuracy is difficult to improve, and also add being manufactured into for hydraulic support
This, and bring difficult and inconvenience to control, operation and maintenance.
And the parallel institution of four-degree-of-freedom is used to realize that hydraulic support is relative as the theme supporting mechanism of hydraulic support
Roof and floor realizes effectively carrying, in addition to the pressure at right angle applied except being primarily subjected to top plate and bottom plate to hydraulic support also subject to from
The cross component force in other directions, the support performance of hydraulic support can be effectively improved, improve the reliability of supporting, security and stably
Property, avoid caving shield damage, fall the generation of the security incident such as frame and downslide, the shortcomings that overcoming existing hydraulic support, weight will be produced
Big social benefit and huge economic benefit.
