Description

A kind of coal mine inclined shaft assembled is laid a railway track construction method
Technical field
The invention belongs to roadway construction technical fields, specifically, being a kind of construction party laid a railway track applied to coal mine inclined shaft Method.
Background technology
Underground coal mine transport is divided into rail travel and flexible transport, flexible transport using rubber tire and crawler type as driving mechanism, Rail travel then mainly uses stringing electric power, anti-explosion diesel engine, accumulator and steel wire rope for traction power.It is domestic except the north at present For a small number of large-scale mines using outside flexible transport, remaining mine mostly uses rail travel.
The traditional method of laying a railway track of well lane engineering is first to transport the materials such as rail, sleeper by haulage inclined shaft hoisting system with wooden handcart To infield, using the construction method manually laid a railway track by root installation.
Tradition is laid a railway track and is disadvantageous in that present in construction method:
1) gradient carries out heavy rail installation in 15 ° or more of inclined shaft engineering, and material handling is difficult, work efficiency is low, speed is slow, input It is of high cost.
2) slope construction security threat is big, and mechanical casualty accident easily occurs and slope machine transports accident.
3) labour's input is especially more, and per tour at least needs to put into 14 people, on the one hand increases labour cost and on the other hand increases Security risk.
4) construction time is long, is often laid with the track of 12.5m standards length, the time that need to be spent about 17-18h.
Invention content
In view of the above-mentioned deficiency of the prior art, technical problem to be solved by the present invention lies in provide a kind of coal mine inclined shaft Assembled is laid a railway track construction method.
Technical scheme is as follows:A kind of coal mine inclined shaft assembled is laid a railway track construction method, it is characterised in that including with Lower step:
1) segmented tracks are assembled in ground-mounted field, which has two or so parallel rail, in rail The more sleepers being mutually parallel are arranged in lower section from front to back, and sleeper is mutually fixed by railway spike or fastener with two one steel rails, and sleeper Damping rubber pad is equipped between rail;
2) use ground handling trolley that segmented tracks are transported to the well head of coal mine inclined shaft;
3) it uses down-hole transportation that first segmented tracks is transported to underground to lay a railway track a little, by preceding hoisting gantry frame with after Hoisting gantry frame slings first segmented tracks, the then extraction below first segmented tracks by down-hole transportation, then will First segmented tracks is placed on the ground of underground;
4) down-hole transportation is returned into well head, while moves backward preceding hoisting gantry frame and rear hoisting gantry frame to next Station is installed;
5) next segmented tracks underground is transported to by down-hole transportation to lay a railway track a little, it will using preceding hoisting gantry frame The tail portion of dress segmented tracks is sling, and is realized the front end of the segmented tracks to be installed on down-hole transportation and has been filled the tail end of segmented tracks The consistent roads Hou Yong clamping plate is docked in docking, fish (-)bolt locks two segmented tracks connections;
6) segmented tracks on down-hole transportation are lifted by crane vacantly using rear hoisting gantry frame, makes the segmented tracks to connecting It detaches with down-hole transportation, then extracts down-hole transportation below segmented tracks out, then pass through preceding hoisting gantry frame and rear It hangs portal frame corresponding segmented tracks are placed on the ground of underground;
7) step step 4) is repeated to step 6), until the last one segmented tracks is completed to place;
8) positioning adjustment is carried out to the track placed according to stringcourse in tunnel, floor is hardened, all work of laying a railway track of completion.
Rail, sleeper, damping rubber pad, railway spike or fastener are first assembled by the present invention in ground-mounted field by design requirement Segmented tracks then use ground handling trolley and down-hole transportation to transport segmented tracks to underground and lay a railway track position, recycle The docking that portal frame carries out two sections of tracks is hung, has used mechanical work to the maximum extent in this way, reduces labour's input, mitigates Labor intensity, effectively increases efficiency of laying a railway track.
The ground handling trolley is made of truck chassis and bracket, and the bracket includes column, joist and crossbeam, two supports Beam or so is parallel and is arranged symmetrically, which is higher than the headstock of truck chassis, and the front end of joist exceeds the front end of truck chassis Face, the rear end of joist exceed the rear end face of truck chassis, the more cross being mutually parallel are provided with from front to back between two joists Beam forms frame structure, which fixes support by four columns by the rectangular distribution, and the bottom end of the column is welded on On truck chassis.Since segmented tracks are up to more than ten meters, ground handling trolley using the above structure can realize segmented tracks It transports;Carrier structure is simple, and intensity is reliable, can ensure during transport firm to segmented tracks support.
Preferably, the column, joist and crossbeam are made of I-beam for mine, it is provided between column and truck chassis Raker beam.
The down-hole transportation is made of preceding unwheeling, rear unwheeling and steel cable, and the preceding unwheeling and rear unwheeling all have band rolling The flatcar of the flatcar of wheel, preceding unwheeling is connect by steel cable with the flatcar of rear unwheeling, the fixing support rack on flatcar, the supporting rack Top is equipped with trustship, and the trustship can be rotated along its axial line.It is flexibly connected using steel cable between preceding unwheeling and rear unwheeling, and It supports the trustship of segmented tracks rotatable, has the function of during underground transportation in this way " adaptive ", can adapt to ground Slope change, so that it is guaranteed that by segmented tracks it is safely unobstructed transport to underground and lay a railway track place.Preceding unwheeling is less than rear unwheeling, waits for Fill track in rear unwheeling with filled with regard to -5 ° of top rakes of self-assembling formation between track, and track front end to be installed and ground are just Form 440cm height.When having filled track follower head and lifting to 440cm height, just docked unanimously with track front end to be installed (data above is according to experiment gained).Front and back unwheeling height, the foundation of front and back frame vehicle headway are controlled using this data as design.
Advantageous effect:Rail, sleeper, damping rubber pad, railway spike or fastener are first pressed design by the present invention in ground-mounted field It is required that be assembled into segmented tracks, then use ground handling trolley and down-hole transportation to transport segmented tracks to underground and lay a railway track position It sets, recycles hoisting gantry frame to carry out the docking of two sections of tracks, used mechanical work to the maximum extent in this way, reduced labour Power is put into, and alleviates labor intensity.Per tour only needs 4 people to carry out operation, reduces than conventional construction method a greater part of.Ground group Dress is that batch production standard is assembled, and quality is easily controllable, and quality of laying a railway track significantly is promoted.The present invention carries out construction work of laying a railway track Industry environment makes moderate progress with respect to conventional construction method, and the insecurity of environment and people reduce many, the danger of major hazard source Degree is reduced.
