The assembly of component 6,2 inner sleeve cartridge modules, I 4,2 inner sleeve cartridge modules II 5 composition gets on the right track in rail assembly 3, and face is opposite to be moved
It is dynamic.
I.e., it can be achieved that following 3 kinds of working conditions under the collective effect of lifting cylinder 8 and oil cylinder 7 of taking a step: 1. taking a step for 2
8 collective effect of oil cylinder 7 and 4 lifting cylinder, the position for realizing that step-by-step movement travelling platform 2 is adopted relative to difference between hole are transferred；②1
A movement of oil cylinder 7 of taking a step, another 1 oil cylinder 7 of taking a step is stationary, realizes 360 ° of the original place steering work of step-by-step movement travelling platform；
3. when 48 disagglutinating actions of lifting cylinder in the 2 walking assemblies 1, it can be achieved that forward and backward end of step-by-step movement travelling platform relative to
The height adjustment on ground works, and the fluctuating on stope ground is preferably adapted to convenient for step-by-step movement travelling platform, enhances being applicable in for equipment
Property.
Herein, it is noted that 4 inner sleeve cartridge modules II 5 of inner sleeve cartridge module I 4,2 of housing cartridge module 6,2 are completed
After first assembly, housing cartridge module 6 and 2 inner sleeve cartridge module I 4 and 2 inner sleeve cartridge modules can be adjusted in real time by adjusting pad 22
Faying face gap between II 5.In later period use process, when equipment maintenance, encounters after briquetting 23 becomes larger because of wearing clearance,
Adjusting pad 22 can be crossed and adjust inner and outer sleeves faying face gap.
In addition, the present embodiment additionally provides the walking workflow of 2 assembly of walking assembly 1 and interlude travelling platform assembly
For journey as shown in fig. 6, can be divided into 5 operating attitudes, each walking operations process of running gear is exactly the circulation adjustment of this 5 postures
Process.Each posture workflow is done as described below:
One, posture 1: initial attitude figure, lifting cylinder 8 are withdrawn completely, and oil cylinder 7 of taking a step is withdrawn completely, and interlude travelling platform is total
It is kept in contact at 2 forward and backward head bottom parts and ground, the bottom and ground of rail assembly 3 are kept at a distance.
Two, posture 2: lifting cylinder 8 is fully extended, and oil cylinder 7 of taking a step is withdrawn completely, and interlude travelling platform assembly 2 is forward and backward
Head bottom part and ground are kept at a distance, and the bottom and ground of rail assembly 3 are kept in contact.When this posture, only 2 rail assemblies
There is contact in 3 bottom and ground, interlude travelling platform assembly 2 leaves ground under the castering action of lifting cylinder 8.
Three, posture 3: lifting cylinder 8 is fully extended, and oil cylinder 7 of taking a step is fully extended, and interlude travelling platform assembly 2 is forward and backward
Head bottom part and ground are kept at a distance, and the bottom and ground of rail assembly 3 are kept in contact.When this posture, only 2 rail assemblies
There is contact in 3 bottom and ground, interlude travelling platform assembly 2 starts under the traction for oil cylinder 7 of taking a step along orbital plane
Movement.
Four, posture 4: lifting cylinder 8 is withdrawn completely, and oil cylinder 7 of taking a step is fully extended, and interlude travelling platform assembly 2 is forward and backward
Head bottom part and ground are kept in contact, and the bottom and ground of rail assembly 3 are kept at a distance.When this posture, interlude travelling platform
Assembly 2 starts to reduce vertical height with withdrawing for lifting cylinder 8, until the forward and backward head bottom part of interlude travelling platform assembly 2
It is kept in contact with ground.
Five, posture 5: lifting cylinder 8 is withdrawn completely, and oil cylinder 7 of taking a step is withdrawn completely, and interlude travelling platform assembly 2 is forward and backward
Head bottom part and ground are kept in contact, and the bottom and ground of rail assembly 3 are kept at a distance.When this posture, rail assembly 3 is with advanced in years
Step oil cylinder 7 withdraws the lower horizontal movement of effect, and until taking a step, oil cylinder 7 reaches range.
By the adjustment of above-mentioned continuous 5 postures, 2 horizontal direction of interlude travelling platform assembly realizes oil cylinder 7 of taking a step
The relative displacement of range, in real work 7 amount of movement of passage oil cylinder number need to be in conjunction with needed for entire exploitation process depending on,
The cycle operation of 5 postures realizes the forward or backward of similar creeper undercarriage, and 1 movement of oil cylinder 7 of taking a step, another 1 steps
Walk oil cylinder 7 it is stationary, it can be achieved that step-by-step movement travelling platform 2 the steering work of 360 ° of original place.
It can be seen that the present embodiment running gear not only realizes step-by-step movement travelling platform relative to the different positions adopted between hole
Set 360 ° of the original place steering work of transfer and entire travelling platform；It can also be achieved the forward and backward head bottom part phase of step-by-step movement travelling platform
Height adjustment work for ground, the fluctuating on stope ground is preferably adapted to convenient for step-by-step movement travelling platform, enhances equipment
Applicability.The running gear is combined into a whole set of Mining Equipment production practice and work flow, can effectively realize highwall pressure coal work
Unmanned, the mechanization production in face.
Above-described embodiment is only one of the preferred embodiment of the present invention, should not be taken to limit protection model of the invention
It encloses, as long as that in body design thought of the invention and mentally makes has no the change of essential meaning or polishing, is solved
