Description
Technical field
This utility model relates to coal mine machinery field, a kind of step type pick being applicable to hard-rock tunnel driving
Enter suspension device, mainly complete quickly propelling of tunnelling operation by big gun pick mode.
Background technology
Currently for the excavation operation of hard-rock tunnel, mainly making in two ways, one is to use hard rock mole to complete, two
It is to use big gun pick operation to complete.It is when using hard rock mole to hard rock cut, very big to cutterhead and equipment damage, it is often necessary to
Change pick and other assemblies.It addition, boom-type roadheader is after cut goes out one section of unsupported back span, top board cannot obtain timely and effective
Supporting, it usually needs recalled by development machine, uses the support apparatus such as special jumbolter that top board is carried out permanent support, thus
Affect drivage efficiency.When carrying out big gun pick operation, the most often hole under conditions of top board does not has good supporting, install fried
, there is great potential safety hazard in the operations such as medicine.
Existing comprehensive tunneler, as the patent of invention that Authorization Notice No. is CN102022122B discloses " a kind of supporting
Formula comprehensive tunneler ", by without crawler type development machine,
Development machine chassis, left and right hydraulic support, rig and drag conveyor composition, development machine is arranged on development machine chassis
On, development machine chassis is provided with two advancing jacks, the other end of advancing jack is respectively with left and right hydraulic support even
Connecing, be respectively provided with side push oil cylinder in the both sides on development machine chassis, the forestope of left and right hydraulic support is respectively provided with one group of wire netting
Memorizer, support main canopy afterbody is hung with rig, and the tail of the first drag conveyor is arranged in the shovel board of development machine, head
With the second scraper conveyor tail overlap joint, the second handpiece of scraper conveyer overlaps with belt transfer tail, at two hydraulic supports
Rear be provided with sled.Although this technical scheme has the advantage of perforating supporting and development machine coal cutting parallel operations, in certain journey
Reduce labor intensity on degree, improve coal mining efficiency.But, it still suffers from following defect: when reach operation, is a point left side half
Support group and right half support group, when support group in a left side half moves forward, left one side of something of back is in non-support state, for
, easily there is top board unstability situation, there is potential safety hazard in soft-rock tunnel.Hard-rock tunnel is generally dug mode based on big gun, uses
Cutting units carries out tunnel and repaiies type, and therefore it cannot be applicable to hard-rock tunnel.Anchor chain is used to drive complete machine to retreat, it is impossible to provide enough
Pulling force, there is limitation in back operation.The reliability and the controllability that use steel wire rope pulling process are the most poor.
Existing comprehensive tunneler, the application for a patent for invention if application publication number is CN104500086A discloses " tunnel
Unmanned digging and anchoring integrated machine ", it mainly includes driving system, induction system, temporary support system, anchor system, driving all-in-one
Water system, sensor-based system, electric control system.Wherein the dialling of the joining place of the shovel board portion in driving system and induction system front end
Material roller bearing can prevent to get stuck in shovel board and drag conveyor front end.Although this technical scheme can be suitable for multiple drift section,
And to a certain extent meet differently pressure under the conditions of carry out tunnel supporting operation.But, it still suffers from following defect: owing to adopting
By some gripper shoes as tunnel supporting mechanism, easily there is top board unstability situation, still can there is potential safety hazard.Use tracked machine
Although the running part of structure can realize back operation to a certain extent, meeting as relatively low in hard rock frictional ground force causes pedrail mechanism row
Enter or retreat extremely difficult.In pedrail mechanism traveling process, may be different due to left and right crawler belt running resistance, cause cut
Position deviation.

Step 3) support cylinder II 11 rises, and drives longeron II 13 and back timber II 14 to rise, and back timber II 14 departs from main
Support group longeron (longeron I 23), arrives by supporting roof until supporting pressure to reach requirement, and host groups pair support group 1 completes one
Secondary advance process of taking a step.
Step 4) support cylinder I 11 declines, and drives longeron I 23 and back timber I 24 to decline, and after back timber I 24 declines, departs from
By supporting roof, it is overlapped on longeron II 13.Collateral backplate I 29 shrinks, and stops the support to tunnel lateral wall.
Step 5) passage oil cylinder I7 stretches out, and drives two pieces of connecting plate I 22, connecting plate I 22 to drive support cylinder I 21, longeron I
23, a step pitch (about 500mm) of the advance such as back timber I 24, support platform 26 and collateral backplate I 29 stops afterwards.
Step 6) support cylinder I 21 rises, and drives longeron I 23 and back timber I 24 to rise, and back timber I 24 departs from secondary support
Group longeron (longeron II 13), arrives by supporting roof until supporting pressure to reach requirement, and collateral backplate I 29 stretchs out, and it is right to complete
The support of tunnel lateral wall.Host groups main support group 2 completes advance process of once taking a step.
, tail unit course of a step:
Step 1) support cylinder IV 311 declines, and drives longeron IV 313 and back timber IV 314 to decline, back timber IV 314 times
After fall, depart from by supporting roof, be overlapped on longeron III 323.
Step 2) connect oil cylinder 6 and passage oil cylinder II 325 retracts, passage oil cylinder III 315 is stretched out by two, drives two pieces
Connecting plate IV 312, connecting plate IV 312 drive a step pitch of the advances such as support cylinder I 311, longeron IV 313 and back timber IV 314
(about 500mm) stops afterwards.
Step 3) support cylinder I 311 rises, and drives longeron IV 313 and back timber IV 314 to rise, and back timber IV 314 departs from
Main support group longeron (longeron III 323), arrives by supporting roof until supporting pressure to reach requirement, tail unit pair support group 31
Complete advance process of once taking a step.
Step 4) support cylinder III 321 declines, and drives longeron III 323 and back timber III 324 to decline, back timber III
After 324 decline, departing from by supporting roof, be overlapped on longeron IV 313, collateral backplate II 33 shrinks, and stops tunnel lateral wall
Support.
Step 5) connects oil cylinder 6 and passage oil cylinder II 325 stretches out, and passage oil cylinder III 315 is retracted by two, drives two pieces
Connecting plate III 322, connecting plate III 322 drive support cylinder III 321, longeron III 323, back timber III 324 and collateral protect
One step pitch (about 500mm) of advance such as plate II 33 stops afterwards.
