Abstract
The utility model discloses an advancing special tunnel support for stope face, comprising a top beam 1. Both ends of the top beam 1 are hinged with supporting oil cylinders 2, and the end heads of the top beam 1 are hinged with face guards 3. The oil cylinders 4 of the face guard oil are respectively hinged with the top beam and the face guards 3. A floating connecting ring 5 is fixed on the top beam 1. A guide way 6 is fastened and arranged on the floating connecting ring. A transporting carrier 7 is fastened on the guide way. The transporting carrier 7 is drawn by a winch via a steel rope 9. The utility model has the advantages of good mechanical property, good carrying capacity, and high mechanization degree. The advancing special tunnel support for stope face is convenient to be assembled and disassembled, the supporting guard is convenient, and the expense of the supporting guard is low. The stability of the tunnel at the end of the stope and in the region which is influenced by the supporting pressure can be kept, and the production and the safety are guaranteed.
Description
The utility model relates to a kind of excavation support, a kind of leading extraordinary excavation support that is applicable to the stope end support of more specifically saying so.
The mechanization degree of China's coal-mine stope has had large increase at present, but also there are many problems in the advance support of stope and end support.Most of mines still adopt i iron rigid support supporting tunnel, ore deposit, but because the pressure of top board changes greatly, this rigid support is difficult to adapt to ahead work face pressure, has caused support badly damaged.Some ore deposit adopt hydraulic prop coordination hinge bar timbering, but mechanization degree is not high in leading pressure influence scope, and complex procedures.
The ubiquitous problem of above support pattern is: the rack bearing ability is low, and mechanization degree is not high, complex technical process, and the support multiplexing number is few, and supporting expense height is difficult to guarantee to produce and safe requirement.
The purpose of this utility model is to have designed in order to overcome above-mentioned the deficiencies in the prior art that a kind of mechanical property is good, supporting capacity is high.Install and tear open and move the leading extraordinary excavation support of stope easily.
The purpose of this utility model can realize in the following manner: the leading extraordinary excavation support of a kind of stope, include back timber, its two ends are hinged with support cylinder, the two ends of back timber is hinged with face guard, the downside of described face guard is hinged with an end of wall supporting oil cylinder, and the other end of wall supporting oil cylinder is hinged on the back timber.
The utility model compared with prior art has the following advantages: it is good that it has mechanical property, the supporting capacity height, and the mechanization degree height, the good stability of support, labour intensity is low, installs and tears open and move conveniently, and the roof supporting number of times is few repeatedly, and the supporting expense is low.This support can keep tunnel stable of stope termination and bearing pressure influence area, make produce and safety secure, have higher popularization and practical value.
Description of drawings:
Accompanying drawing 1 is a structural representation of the present utility model.
Accompanying drawing 2 is the vertical arrangement diagrams of the utility model.
The utility model is described in further detail with reference to the accompanying drawings:
Shown in accompanying drawing 1: the leading extraordinary excavation support of a kind of stope has back timber 1, and described back timber 1 usefulness shaped steel is made, and it can be made into straight or arch, is used for satisfying the needs in cross section, tunnel.The hinged support cylinder 2 in the left and right sides of back timber 1, described support cylinder 2 is selected light-duty two-way cylinder for use, can be identical according to the length of the left and right sides, the cross section support cylinder 2 in tunnel, also can be different, can form the supporting of positive rectangle or the tiltedly supporting of rectangle.At the articulated face guard 3 in the left and right both ends of back timber 1, an end of wall supporting oil cylinder 4 is hinged on the back timber 1, and the other end is hinged on the downside of face guard 3, during use, relies on wall supporting oil cylinder 4 supporting face guard 3, avoids the tunnel sidewall to help partially.Be fixed with the connecting ring 5 that floats at back timber 1 middle part, there is " Jiong " type groove the lower end of the connecting ring 5 that floats, and guide rail 6 is stuck in the groove, and described guide rail 6 is used i iron, and travelling bogie 7 is installed on the guide rail 6." Qian " type bearing support is arranged on the described travelling bogie 7, and its side plate inboard is fixed with wheel, and the bearing support downside has girder, and chain is arranged on it, is used for fixing and is moved support.
Vertical arrangement diagram of having showed support with reference to accompanying drawing 2: Fig. 2.Support whenever is spaced a distance and arranges a support, guide rail 6 is fixed on the back timber 1 of support by the connecting ring 5 that floats, travelling bogie 7 is installed on the guide rail 6, the two ends of guide rail 6 are fixed with pulley 8, pass pulley 8 with wire rope 9, and the middle part of wire rope 9 is fixed on the travelling bogie 7, makes wire rope 9 can affect travelling bogie 7 to slide along guide rail 6.
The back moves on to the foremost to second from the bottom, and circulation is carried out successively, moves frame and adopts whole transportation.Its process is that wall supporting oil cylinder and support cylinder shrink, back timber whereabouts and face guard are inwardly shunk, wait back timber to fall certain altitude, tangle back timber with the chain on the travelling bogie, then, support cylinder continues to shrink, and makes support cylinder liftoff, then allows support integral body rotate an angle, then by winch traction travelling bogie, from after support is pulled to front end, rise support again, move frame at every turn and repeat said process.According to the cross section in tunnel, can select the length of the shape of back timber and support cylinder to satisfy the needs of drift section.
