Description
Technical field
The utility model belongs to coal mine down-hole tunnel temporary lining technical field, relating to a kind of overall movement fast of energy in the soft inbreak situation of coal of enclosing at coal mine down-hole tunnel top, entirely enclose the safety support device that the tiny fragments of stone, coal, etc. is not leaked in shielding, being specifically related to a kind of for tunneling the shield structure support with back production.
Background technology
At present at stope, particularly caving coal mining work plane, two lane advance supports are emphasis and the difficult point of roadway support.Reason is, work plane is in exploitation process, and the advanced 20 meters of inside ceiling panel pressure in two lanes are obviously greater than tunnel other parts, and advanced section is along with the propelling of work plane is also in continuous change.Existing supporting generally adopts hydraulic prop to add π section steel beam mode, this mode globality is poor, need manually more, translational speed is slow and dangerous; Other is as advance timberings such as combination beam type excavation support, double leval jib step type excavation supports, most of complex structure, and action is loaded down with trivial details, and mainly with being main to roof timbering, does not have supporting to roadway's sides, is difficult to adapt to the soft coal seam that easily emits or country rock.
Publication number is that the Chinese patent of CN203531931U discloses underground coal mine temporary support for drivage face equipment, comprise support, cylinder, hook and forestope, it is characterized in that, support has uniform vertically upward 4, frame upper is equipped with 2 groups of symmetrical slide mechanisms, slide mechanism comprises hook, gripper shoe, forestope and cylinder, hook is contained on support, the gripper shoe that transverse horizontal is arranged is equipped with in hook bottom, the forestope having horizontal arrangement in the sliding channel perpendicular to gripper shoe is formed between gripper shoe and support, cylinder is contained in forestope through linkage is parallel, there is stay hook the piston rod end of cylinder, described linkage comprises the first fixed head, the second fixed head, screw bolt and nut, and cylinder is contained on the first fixed head, and the first fixed head is connected with the second fixed head being contained in the inner both sides of forestope through bolt, and bolt two ends have for fixing nut.The pressing plate of described hook through top is fixed on support; Described support is circular arc.This underground coal mine temporary lining equipment is only provided with support, and this support belongs to horizontal support, to the unrestrained then non-support ability of the coal tiny fragments of stone, coal, etc. from coal mine roadway inner top longitudinal direction.
Publication number is that the Chinese patent of CN203308478U discloses temporary lining frame, comprise left support plate, right support plate, and some top boards, it is characterized in that, also comprise left hydraulic cylinder, right hydraulic cylinder, and some upper hydraulic cylinders, the two ends of described upper hydraulic cylinder connect two pieces of top boards respectively, one end and the left support plate of described left hydraulic cylinder are hinged, and the other end is hinged with the top board being connected left support plate; One end and the right support plate of right hydraulic cylinder are hinged, and the other end is hinged with the top board being connected right support plate; Described upper hydraulic cylinder is asymmetric to be hinged on two pieces of top boards.Described left support plate, between each top board and right support plate by being hinged and connected, and by hydraulic system, operating angle to be regulated and controled.This temporary lining frame must rely on external force to arrive assigned address, when concrete operations, wastes time and energy, efficiency is low.
Publication number is that the Chinese patent of CN201802428U discloses temporary support device for coal mine heading, comprises pressure pin, connector and cylinder; One end of pressure pin is provided with fastening devices, and the other end is connected with cylinder by connector; Cylinder has air inlet, and the opening part of air inlet is provided with control valve; Bottom the piston rod of cylinder, non-slip feet is installed.This temporary support is operationally: that one end of pressure pin being equipped with fastening devices is placed on the work plane of firm explosion, the other end is connected with cylinder by connector, top power is made to be attributed to top board to 50-55 degree cylinder angular adjustment, control valve is connected with external pressure pipe, thus cylinder must be pressed, piston rod stretches out and makes that holder is dry withstands top board.This temporary support device for coal mine heading only can realize the supporting of local, for from non-mask then non-support ability, and poor practicability.
In addition, existing support pattern, ubiquity support process is complicated, and the slow-footed problem of integer support, can not adapt to the requirement of face mechanization high-efficiency mining.In addition, in tunnelling process, no matter big gun pick or machine are dug and are all related to advanced temporary lining problem, and the original backwardness of current Measures compare, greatly have impact on driving speed and safety.For this reason, a kind of globality is strong, mobile rapidly, supporting is safely and efficiently imperative.
