Description
Technical field
The present invention relates to coal mine machinery field, specifically a kind of step type driving branch tunneled suitable for hard-rock tunnel
Protection unit, mainly completes quickly propelling for tunnelling operation by way of big gun pick.
Background technology
Currently for the excavation operation of hard-rock tunnel, mainly using two ways, one is completed using hard rock mole, two
It is to be completed using big gun pick operation.It is very big to cutterhead and equipment damage during using hard rock mole to hard rock cut, it is often necessary to
Change pick and other assemblies.In addition, boom-type roadheader is after cut goes out one section of unsupported back span, top plate can not obtain timely and effective
Supporting, it usually needs recall development machine, permanent support is carried out to top plate using support apparatus such as special jumbolters, thus
Influence drivage efficiency.When carrying out big gun pick operation, often do not have in top plate manually to be drilled under conditions of good supporting, install and fry
, there is great potential safety hazard in the operations such as medicine.
Existing comprehensive tunneler, such as Authorization Notice No. disclose a kind of " supporting for CN102022122B patent of invention
Formula comprehensive tunneler ", by without crawler type development machine,
Development machine chassis, left and right hydraulic support, rig and drag conveyor composition, development machine are arranged on development machine chassis
On, two advancing jacks are installed, the other end of advancing jack connects with left and right hydraulic support respectively on development machine chassis
Connect, side push oil cylinder is respectively installed 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
Memory, 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
Overlapped with the second scraper conveyor tail, the second handpiece of scraper conveyer is overlapped with belt transfer tail, in two hydraulic supports
Rear be provided with sled.Although the technical scheme has the advantages that perforating supporting and development machine coal cutting parallel operations, in certain journey
Labor intensity is reduced on degree, coal mining efficiency is improved.But, it still suffers from following defect：It is a point left side half when moving forward operation
Support group and right half support group, when left half support group is moved forward, left one side of something of back is in non-support state, for
Soft-rock tunnel, easily occurs top plate unstability situation, there is potential safety hazard.To hard-rock tunnel generally based on big gun pick mode, use
Cutting units carries out tunnel repairing type, therefore it can not be applied to hard-rock tunnel.Complete machine is driven to retreat using anchor chain, it is impossible to provide enough
Pulling force, there is limitation in back operation.The reliability and controllability for pulling process using steel wire rope are poor.
Existing comprehensive tunneler, such as application publication number disclose " tunnel for CN104500086A application for a patent for invention
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.Shovel board portion and group of the joining place of induction system front end wherein in driving system
Material roller bearing can prevent to get stuck in shovel board and drag conveyor front end.Although the technical scheme can be adapted to a variety of drift sections,
And progress driving supporting operation under the conditions of differently pressure is met to a certain extent.But, it still suffers from following defect：Due to adopting
With some supporting plates as tunnel supporting mechanism, easily occur top plate unstability situation, can still there is potential safety hazard.Using tracked machine
Although the running part of structure can realize back operation to a certain extent, such as hard rock frictional ground force is relatively low to cause pedrail mechanism row
Enter or retreat extremely difficult., may be different due to left and right crawler belt running resistance in pedrail mechanism traveling process, cause cut
Position deviation.
The content of the invention
Suspension device is tunneled it is an object of the invention to provide a kind of step type suitable for hard-rock tunnel driving, fundamentally
