The technical problem to be solved by the invention is to provide the sling capable of monitoring and maintaining the whole service life aiming at the prior art, and the sling is correspondingly subjected to dry air maintenance, so that the energy is saved, the environment is protected, the sling diseases are cured, and the safety of the sling in the bridge operation period is ensured.
The invention solves the problems by adopting the following technical scheme: the utility model provides a maintainable life hoist cable, includes cable body, hoist cable sheath, connecting cylinder and lower extreme anchor cup, the connecting cylinder sets up in lower extreme anchor cup upper end, and the cable body passes the connecting cylinder downwards and the tip anchor is in lower extreme anchor cup, hoist cable sheath cover is established on the cable body of connecting cylinder top, by the local shell of cable body of hoist cable sheath parcel exposes the wire bundle, and clearance between the hoist cable wire bundle is as dry air circulation clearance D1, the wire bundle of cable body lower extreme is the toper and spreads out and anchor and form the toper cast body in lower extreme anchor cup, the clearance between toper cast body and the lower extreme anchor cup inner wall is as dry air circulation clearance D2, dry air circulation clearance D1 communicates with dry air circulation clearance D2 from top to bottom.
A sight opening is formed in the sling sheath, a monitoring window frame is fixed on the sight opening, and a transparent window is inlaid in the monitoring window frame and is used for monitoring the corrosion degree of the surface of the steel wire; the sling sheath is also provided with a dry air inlet and a detection port for detecting the humidity in the sling body, the dry air inlet is directly communicated with the dry air circulation gap D1, the outer wall of the lower anchor cup is provided with a dry air outlet, and the dry air outlet is communicated with the dry air circulation gap D2.
The interval distance between the position of the viewing port and the connecting cylinder is 0-100 dm.
The view port is annular or annular discontinuous.
And the dry air inlet is provided with a flow valve for controlling the dry air to be introduced into the rope body.
Compared with the prior art, the invention has the advantages that: a sling capable of monitoring maintenance life span is provided, and the corrosion condition of the surface of a steel wire is observed through a transparent window; the reserved detection pipeline detects the humidity in the rope body, corresponding dry air maintenance is made in a targeted manner, diseases of the sling are cured, the normal state of the sling is recovered, and the novel intelligent rope sling has the characteristics of high efficiency, energy conservation, environmental protection and the like. The technology ensures the safety of the sling in the operation period of the bridge, and truly realizes the concept of the same service life of the sling and the bridge.

FIG. 2 is a partially rotated enlarged view of a maintainable full life sling according to an embodiment of the present invention;
FIG. 3 is a partial cross-sectional view of a maintainable full life sling according to an embodiment of the present invention;
in the figure, a dry air inlet, a valve 2, a transparent window 3, a sling sheath 4, a monitoring window frame 5, a dry air outlet 6, a lower anchor cup 7, a conical casting body 8, a connecting cylinder 9 and a cable body 10 are arranged.
Detailed Description
The invention is described in further detail below with reference to the embodiments of the drawings.
As shown in fig. 1, 2 and 3, the maintainable life-span sling in this embodiment includes a cable body 10, a sling sheath 4, a connecting tube 9 and a lower anchor cup 7, wherein the connecting tube 10 is fixed at the upper end of the lower anchor cup 7, the cable body 10 passes through the connecting tube 9 downwards and is anchored in the lower anchor cup 7, the sling sheath 4 is arranged at the periphery of the cable body above the connecting tube 9, the sling sheath 7 is spaced from the connecting tube 9 by 30-40dm, the cable body 10 wrapped in the sling sheath 4 is partially stripped of polyethylene sheath to expose bare steel wire bundles, and the gap formed between the steel wire bundles in the cable body is used as a dry air circulation gap D1.
Specifically, the steel wire bundle at the lower end of the rope body 10 is scattered in a conical shape after the polyethylene sheath is stripped off and is anchored in the lower anchor cup 7 to form a conical cast body 8, after the anchoring, a shrinkage gap formed between the conical cast body 8 and the inner wall of the lower anchor cup is used as a dry air circulation gap D2, and obviously, the dry air circulation gap D1 and the dry air circulation gap D2 are communicated up and down.
A ring-shaped view port or a ring-direction discontinuous view port is formed in the sling sheath 4, a matched monitoring window frame 5 is arranged on the opened view port, a transparent window 3 is inlaid on the monitoring window frame 5, and the rust degree of the surface of the steel wire is observed through the transparent window 3; the transparent window is also provided with a dry air inlet 1 and a detection port for detecting the humidity in the cable body, the dry air inlet 1 is communicated with a dry air circulation gap D1, and a valve is arranged on a pipeline of the dry air inlet 1 and used for controlling the flow of the dry air into the cable body. The lower anchor cup 7 is provided with a dry air outlet which is communicated with the dry air circulation gap D2, and dry air enters the dry air circulation gap D1 through the dry air inlet and flows into the dry air circulation gap D2, and the wire bundle is subjected to dry air maintenance and flows out through the dry air outlet.
The area with serious corrosion at the lower end of the sling is monitored and maintained, and the corrosion condition of the surface of the steel wire is observed through the transparent window 3. Detecting the humidity in the cable body through a reserved detection pipeline, and when the humidity meets the requirement, the valve 2 is in a normally closed state; when the humidity exceeds 60%, the dry air is dehumidified, the valve 2 is opened, the dry air is introduced into the cable body through the dry air inlet 1, the sling is dehumidified, and then the dry air flows out through the dry air outlet pipeline 6.
