Description
Technical field
The invention belongs to coal mine roadway driving technology fields, and in particular to a kind of roadway head protects top and anchor temporarily
The construction integrated device of bar.
Background technology
It is one of current principal element for influencing the production of China's mine high-yield and high-efficiency that coal mine digging is unbalance.Coal mining machinery
The change level of informatization is higher and higher, and drawing speed is getting faster, but tunnelling speed does not significantly improve really.Coal mine crossheading is dug
Into speed generally in the 200-400m/ months, and drawing speed is in the 300-400m/ months, and a stope crossheading length is general
It it is 3 times or so of working face strike length, along with working face equipment installs time, general work face crossheading is required for carrying
First 2 years or so drivings, lead to that more heading end, Gong Renduo, efficiency are low, maintenance cost is high.For special circumstances, such as dug using along sky
Lane, gob side entry need to tunnel after erecting dense individual props are compacted, and at least lag last more than working face 400m, then digging anxiety is closed
System is then more prominent.
There are three types of tunneling methods at present, and most commonly used is the tunneling method of development machine+monomer jumbolter, that is, after digging i.e.
Anchor, such mode are that one knife of driving makes a call to row's anchor pole, and speed of application is slower；The second way is in the preferable situation of roof condition
Under, it is primary to tunnel 2-6 knives, suspension roof support is then carried out, anchor after this i.e. so-called preceding pick can improve driving speed and efficiency,
But such situation needs roof condition preferable, and application conditions are limited at present, while runs counter to job specfication；The third mode is then
The most fast mode of driving speed at present, front driving, rear is parallel to carry out supporting operation, and pick branch needs top plate at a distance of more than 10m
Condition is more stablized, meanwhile, high equipment cost, size is big, and removal of home stopping surface difficulty is big.
In order to improve driving speed, " the more anchors of pick " are effective modes, but need to provide gib, and the present invention is to carry
A wide range of gib is capable of providing for one kind and development machine is independent of each other, top plate whole process has supporting, " pick is more for technique satisfaction
The device of anchor " technological requirement.
Invention content
Be capable of providing a wide range of gib the object of the present invention is to provide one kind, be independent of each other with development machine, top plate it is complete
Journey has supporting, technique to meet " the more anchors of pick " technological requirement, equipment lightweight, lane small to roof destruction degree, stability is high
Road driving face protects top and anchor bolt construction integrated apparatus temporarily.
The present invention adopts the following technical scheme that realize：
Roadway head protects top and anchor bolt construction integrated apparatus temporarily, including single group stent, two telescopic arms, shield
Push up panel, two suspension columns and rotating hanging roof bolter mechanism；Wherein,
Single group stent includes two pedestals being arranged in parallel and the top beam being arranged on above corresponding pedestal, two top beams it
Between linked together by several transversal stretching beams being arranged in parallel, by lifting supporting mechanism between top beam and corresponding pedestal
It links together；
The lateral central axes of shield top panel are provided with jackshaft, and jackshaft fixes the telescopic oil cylinder in both ends for middle part；
Two telescopic arms are symmetrically arranged in front of single group stent, the head end of each telescopic arm on a corresponding pedestal forepart
The ear mount connection of setting, telescopic arm end are connect with the intermediate shaft end in the panel of shield top, pass through branch in the middle part of each telescopic arm
Arm oil cylinder is connected with a corresponding pedestal；
Suspension column is telescopic oil cylinder, and the top of two suspension columns is connect respectively with the both ends of jackshaft；
Rotating hanging roof bolter mechanism includes two rotating hanging oil cylinders, 1 solid anchor case, several jumbolters and two rotation oil
Cylinder, each rotating hanging oil cylinder one end are connect with intermediate shaft end head, and the other end is connect with solid anchor case, and several jumbolters are fixed on
Anchor upper box part, each rotating hanging oil cylinder middle part passes through rotational fuel tank and the front end of corresponding telescopic arm connects.
Further improve of the invention is that lifting supporting mechanism includes being connected to hanging down between top beam and corresponding pedestal
Straight guide rod and two columns for being arranged on vertical guide stem both sides.
Further improve of the invention is that vertical guide stem is sleeved on the guiding in guide sleeve including guide sleeve and one end
Bar, the bottom of guide sleeve are set on the base, and the other end of guide rod is connected on corresponding top beam.
Further improve of the invention is that lifting supporting mechanism includes be connected between top beam and corresponding pedestal four
Link mechanism and two columns for being arranged on four-bar mechanism both sides.
Further improve of the invention is that telescopic arm includes a joint arm, two joint arms and top telescopic oil cylinder, a joint arm one
Connect base front end is held, two joint arm one end, two joint arm other ends connection jackshaft are socketed on outside the other end, top telescopic oil cylinder is put
The top outside telescopic arm, and top telescopic oil cylinder one end connects a joint arm, the other end connects two joint arms.
Further improve of the invention is that the face profile shape of shield top panel is rectangle, laterally there is bar shaped hollow out,
Uniform intervals are provided with several cushion blocks above the panel of shield top.
Further improve of the invention is that the quantity of jumbolter is 2-4 platforms.
Further improve of the invention is that each pedestal horizontal direction is equipped with several vertically arranged lateral with pedestal
Oil cylinder, for adjusting the gap of the device and roadway's sides.
The present invention has following beneficial technique effect：
Roadway head provided by the invention protects top and anchor bolt construction integrated apparatus temporarily, and device structure simply may be used
It leans on；It is light-weight；The frictional force that the generation of oil cylinder branch side is stretched out by both sides pulls single group stent, reduces and shield top panel is disturbed
It is dynamic；It is rigidly connected, changed by the way of lateral connection, structural integrity using transversal stretching beam between two rows of unit racks
Height, stability greatly improve；" one anchor of pick " is optimized for " the more anchors of pick ", realizes the flat of top anchor pole, anchor cable and side anchor pole
