Embodiment
As in Fig. 1, a kind of heavy in section length comprises apart from high drop cable machinery unfolding system the electric power conveyer 1, straight line coaster 3, ring-like coaster 4, the corner tackle pulley 5 that are located between cable hank 2 and cable drawing machine 6, and corner tackle pulley 5 is located at turning;
Be provided with at each ring-like coaster 4 and cable 7 contact-making surface and pressure inductor 8 is all set, as in Fig. 5, it is No. 1 that pressure inductor 8 is compiled successively, No. 2 ... to No. N, preferably, data acquisition unit 9 is connected with pressure inductor 8, and collect the pressure value of the pressure inductor 8 of each ring-like coaster 4, ring-like coaster 4 often rotates a circle, pressure inductor 8 at least can gather a cable 7 and ring-like coaster 4 pressure value, if there is cable drawing machine 6 cannot trailing cable 7 time, namely when cable 7 cannot move, first few minutes pressure value change curve can be checked, on adjacent two ring-like coasters 4, occur that a pressure value declines, the situation that another pressure value rises, namely can prove, the stuck picture occurred between these two ring-like coasters 4 is existing.
Preferably, cable hank 2 is the cable hank of braking device.
as in Fig. 2, arrange one respectively at the discrepancy in elevation two endcable drawing machine 6, is provided with straight line coaster 3 on the slope, and slope two end arranges a ring-like coaster 4 respectively.
As in Fig. 3, set up a cable drawing machine 6 separately on limit, turning two, between the cable drawing machine 6 of two, turning, be provided with corner tackle pulley 5.
In Fig. 4, in cable gallery mouth, establish a cable drawing machine 6, at cable gallery mouth peripheral hardware cable hank 2, in cable gallery mouth place and road junction, at least respectively establish an annular coaster 4.
In Fig. 5, preferred snakelike fixing, comprise support 10 that at least three groups are parallel to each other, support 10 be located at fixture 11, cable 7 under coaster 12 guides successively through fixture 11.
implementation step:
1, the preparation of construction equipment, equipment
By required facility, material before construction, detect, the instrument and meter of test on deck, and the equipment come into operation to all, facility, instrument and meter carefully all should check, clean, clean and check.
2, channel cleanup
Cleaning clean thus on cable trace must to clean out all stones or other may damage the object of cable.Check that bending radius when cable trace must guarantee that cable is installed meets the demands.Arrange construction power supply and lighting along cable run, the security protection of the scaffold used when checking that cable rack is installed, guarantees to use safely.
3, coaster and telpher are installed
Corner tackle pulley, annular coaster are arranged in all turnings, and the layout of corner tackle pulley should guarantee the bending radius > 15D of cable, and radius of turn should be large as far as possible; Corner tackle pulley adopts angle steel, expansion bolt etc. and structures fixation around.Arrange telpher according to stressing conditions, typical facility are arranged and are seen Fig. 1 ~ Fig. 5.Facility should arrange each control cabinet while arranging, and control cables, and facility deploy, and carry out wiring to control loop, and charged debugging, finally need to carry out Coupled motion debugging.
4, cable hank is in place
Laying starting point layout cable hank.Make cable draw from the top of cable hank when should notice that cable hank is in place, avoid in laid processes, when stopping traction, the cable that dish relaxes and earth surface and be scratched or make Cable Bending Radius too small.After cable hank is in place on cable rack, starts brake apparatus is installed, install and debug, guarantee that braking effect is good.For guaranteeing the stable of cable hank, adopting earth anchor and bracing wire attached cable frame, preventing from toppling.
5, cable laying
In all gallerys, along cable trace, 1 controllers is set every 30 meters, is responsible for control cables and normally advances on all coasters, control coaster and normally work (keeping correct direction), and control cables does not produce with body of wall or metallic support and rubs.
6, cable is fixed
(1) at tunnel horizontal cable interlayer internal fixtion cable
According to construction plan installing cables, form snakelike layout (vertical snakelike sagging: to be about D, the D=outside diameter of cable), fix with fixture.In addition, the cable needs that also a minimum range 100mm should be had to expand to meet cable with metope or support.Cable is installed into slight sine curve when moving towards, and cable, under longitudinal thermal expansion influence, can make it move freely by increasing or reduce wave amplitude.
(2) cable is in the shaft fixed
From bottom cable end, fasten fixture upwards extend to top cable end one by one, gradually slight from top releases cable to form the sag of an about 150mm between two continuous print fixtures.Where necessary, winch and conveyer can be used gently to draw forward cable snakelike to become.
