Description
Technical field
The present invention relates to a kind of dragline anchorage front end water-tight devices, are particularly suitable for dragline anchorage sealing drum and free rope
The waterproof sealing cover of body transition connection portion position.
Background technique
Existing drag-line oversheath all uses HDPE to be protected, dragline anchorage sealing drum and free cable body transition connection portion
Position generallys use thermal shrinkable sleeve or pyrocondensation belt carries out waterproof sealing (referring to Figure 10), and cable body is avoided to enter rain by transition junction
Water, and thermal shrinkable sleeve or pyrocondensation belt pyrocondensation at this position be it is fixed, do not adapt to the technical requirements that drag-line PE expands with heat and contract with cold, mesh
The drag-line of some preceding bridges is since the needs of structure are to be connected to box beam anchor point by pull rod, and thermal shrinkable sleeve is with regard to exposed in bridge
On bridge floor；Due to weather, the PE of drag-line is stretched at sealing drum by the active force to expand with heat and contract with cold to be slid, herein
Thermal shrinkable sleeve or pyrocondensation belt are easy under the telescopic action power of PE, are wrecked, and are caused cable body seal failure, are led to dragline anchorage
Water inlet accelerates the corrosion of anchorage, and material contracting with heat generally only has the thickness of 2mm, and the outer of other factors is vulnerable on bridge floor
Power is destroyed, moreover, long-term exposed be exposed to the sun of material contracting with heat hardens, and service life also greatly reduces (referring to Figure 10).
Authorization Notice No. is that a kind of utility model patent " suspension cable beam-ends tarpaulin " of CN203782569U discloses one
Kind suspension cable beam-ends water-tight device, although can partially solve the above problems, but has the following disadvantages:
1, the device and cable body connecting pin, which exist, has the gap, and carries out extrusion deformation sealing, lower end filling sealing by filling sealing strip
Item extruding is mounted on built-in pipe, prevents cable body to expand with heat and contract with cold free to slide, there are internal stress inside PE, cause when serious
PE accelerated ageing, cracking, causes cable body to be intake, shortens the service life of drag-line；
2, the big end needs of the device waterproof cover, which are located, is mounted on built-in pipe, and when cable body PE expands with heat and contract with cold, the mobile of PE will make
The small end seal failure of waterproof cover, cannot drive the movement of waterproof cover, so as to cause cable body water inlet；
3, the device waterproof cover is fixed on cable body and beam-ends built-in pipe exit by the extrusion deformation of three seals item, cable body
When PE expands with heat and contract with cold PE it is mobile it is possible drive waterproof cover mobile, so as to cause waterproof cover is moved out built-in pipe and leak, it is rotten
Lose anchorage.
Summary of the invention
It is an object of the invention to: a kind of suitable for there is PE to expand with heat and contract with cold requirement, exposed skyborne guy anchor is provided
Have front end water-tight device --- it is a kind of suitable for PE sheath expands with heat and contract with cold outside drag-line water-tight device；The water-tight device being capable of basis
The sliding requirement that drag-line PE expands with heat and contract with cold, it is flexible to slide, the waterproof action to anchorage front end PE transition exit can be played, and
It is simple with installation, durable, the features such as extending the cable body service life, the deficiency of existing thermal shrinkable sleeve is compensated for, and filled up drag-line
PE, which expands with heat and contract with cold, slides the guard technology vacancy of caused waterproof problem.
The technical solution to solve the above problems is: a kind of suitable for the water-tight device that PE sheath expands with heat and contract with cold outside drag-line, packet
Include waterproof umbrella, matched screw or bolt pair, it is characterised in that: the waterproof that the outer PE sheath of drag-line expands with heat and contract with cold should be suitable for
Device further includes a sliding inner lining body；
The waterproof umbrella is left and right two halves formula, and seam crossing is straight line or is tooth form or is broken line, the two halves formula waterproof rain
After umbrella is fastened by mounting hole I, mounting hole II using screw or bolt, connection forms the waterproof object of a umbrella shape
Body；Waterproof umbrella upper end is fastened outside drag-line on PE sheath by mounting hole I using screw or bolt pair, waterproof umbrella
Lower part is provided with sliding inner lining body installation groove III, slides using made of the material small with sealing drum contact slide coefficient of friction
Inner lining body is mounted in the installation groove III of waterproof umbrella lower part, fastens peace by mounting hole II using screw or bolt pair
Dress, covers on sealing drum, the sliding liner physical efficiency is free to slide on drag-line sealing drum with expanding with heat and contract with cold for PE sheath, thus band
The waterproof umbrella of dynamic water-tight device can be with the upper and lower sliding of expanding with heat and contract with cold of PE.
Its further technical solution is: should be suitable for the water-tight device that the outer PE sheath of drag-line expands with heat and contract with cold further includes a cunning
Dynamic inner liner support cylinder, the sliding inner liner support cylinder is fixed on sealing drum using two halves formula, using welding manner or packing
Envelope binder mode is linked to be an entirety, and the sliding liner physical efficiency is sliding on sliding inner liner support cylinder with expanding with heat and contract with cold for PE sheath
It is dynamic, to drive the waterproof umbrella of water-tight device can be with the upper and lower sliding of expanding with heat and contract with cold of PE.
Its further technical solution is: the sliding inner lining body is strip, including plane formula slides inner lining body I or convex
