Five, through changing the jack of different tonnages, the realization of safety is to the replacing of the rope of different Suo Li.
Description of drawings
Fig. 1 is a more changing device composition of a kind of sling of suspension bridge of the utility model;
Fig. 2 is the A-A sectional view of Fig. 1;
Wherein, 1, main push-towing rope; 2, location saddle; 3, straddle-type cable wire; 4, first ground tackle; 5, vertically-displacable sensor; 6, feed-through hydraulic jack; 7, underpin bucket; 8, nut; 9, computer data acquiring control system; 10, backing plate; 11, threaded rod; 12, pin; 13, steel case beam; 14, hoist cable to be replaced; 40, second ground tackle.
The specific embodiment:
Be elaborated below in conjunction with the technical scheme of accompanying drawing to the utility model:
As depicted in figs. 1 and 2, a kind of sling of suspension bridge more changing device by location saddle 2, straddle-type cable wire 3, first ground tackle 4, vertically-displacable load sensor 5, feed-through hydraulic jack 6, underpin part 7, nut 8, computer data acquisition system 9, backing plate 10, threaded rod 11, pin 12, second ground tackle 40 and form.
Concrete arrangement form is fixed on the main push-towing rope 1 for location saddle 2; Adjacent on hoist cable to be changed 14 next doors; Straddle-type cable wire 3 rides on the saddle 2 of location, and sagging two ends are fixed on the backing plate 10 by first ground tackle 4, and steel plate one face down bonding of corresponding anchoring below hoist cable 14 to be changed connects the perforate steel plate of a same thickness; Threaded rod 11 passes backing plate 10 and is positioned on the perforate steel plate that extends away by pin 12; What above backing plate 10, lay is to underpin part 7, and a nut 8 is arranged on the threaded rod 11 in underpining part 7, is vertically-displacable jack 6, vertically-displacable load sensor 5, second ground tackle 40 successively underpining above the part 7;
Computer data acquiring control system 9 is connecting vertically-displacable load sensor 5.
The sagging two ends of said straddle-type cable wire 3 and threaded rod 11 are all vertical passes said backing plate 10, the second ground tackles 40, vertically-displacable load sensor 5, feed-through hydraulic jack 6, the center that underpins bucket 7 and threaded rod 11 axle center on same straight line.
During the work of the utility model device, comprise the steps:
The first step is provided with more changing device of sling of suspension bridge between main push-towing rope 1 and steel case beam 13, corresponding anchor plate one face down bonding connects the perforate steel plate of a same thickness below hoist cable to be changed, is used for fixing to connect said support drawing device;
Second step; Through the feed-through hydraulic jack is applied active force; Power on the hoist cable 14 to be replaced is transferred to more changing device bear, the Load Transfer approach that the active force of feed-through hydraulic jack 6 makes progress is: feed-through hydraulic jack 6 → vertically-displacable load sensor 5 → the second ground tackles 40 → threaded rod 11 → pin 12 → steel case beam 13; The downward Load Transfer approach of the active force of feed-through hydraulic jack 6 is: feed-through hydraulic jack 6 → underpin bucket 7 → backing plate 10 → the first ground tackles 4 → straddle-type cable wire 3 → location saddle 2 → main push-towing rope 1;
The 3rd step: remove old rope; Change new rope---when load transfer that hoist cable 14 to be replaced is born itself after bear by the feed-through hydraulic jack 6 on the changing device more; Underspin nut 8 to backing plate 10 upper surfaces, the ground tackle of removal hoist cable 14 to be replaced takes out hoist cable 14 to be replaced then; Change new hoist cable, new ground tackle is installed;
The 4th step: realize the transfer of changing device more → new hoist cable power---the active force of removal feed-through hydraulic jack 6 progressively; On revolve nut 8 to underpining bucket 7 tops, 6 oil returns of feed-through hydraulic jack, removal load gradually, the power pipeline makes the hoist cable of new replacing stressed still according to first step transmission, accomplishes and changes.
Above-mentioned feed-through hydraulic jack 6 upwards acts on jacking and unloading downwards, all through the stress of the thin bar 11 of computer data acquiring control system 9 monitoring screw threads, measures the Suo Li of hoist cable 14 to be replaced simultaneously and changes the later cable force that hangs.
