Description
Technical Field
The utility model relates to a hoist technical field specifically is a special lifting device for interim carrier cable.
Background
The temporary bearing cables are special auxiliary cableway systems for installing and dismantling the bearing cables of the cable crane, four temporary bearing cables used for dismantling the low-platform cable crane of the white beach hydropower station are all steel wire ropes with the diameter of 50mm, and the installation span of the temporary bearing cables exceeds 1100m.
In the dismantling construction of the cable machine of the white beach, the sag of the temporary bearing cable is 76m, and the temporary bearing cable is interfered with the downstream wave wall of the dam 4 dam section (the high cable is 2 dam sections). Therefore, the support frame is placed at the interference position, and when the temporary bearing horse passes through the support frame, the temporary bearing horse can pass through the support frame smoothly only by using a truck crane for auxiliary lifting. When using the wire rope hoist as the lifting appliance, the interval of four interim carrier cables can change to when interim carrier cable is installed on interim carrier cable, can change the interval of interim carrier cable when lifting by crane, cause interim carrier cable to jump the groove from interim carrier cable walking wheel, cause the construction risk, also will damage interim carrier cable simultaneously.
We therefore propose a special spreader for temporary load lines in order to solve the problems set out above.
SUMMERY OF THE UTILITY MODEL
An object of the utility model is to provide a special lifting device for interim carrier cable to solve the problem that proposes among the above-mentioned background art.
In order to achieve the above object, the utility model provides a following technical scheme: a special spreader for temporary load lines, comprising: the lifting lugs are symmetrically fixedly mounted on the left and right sides of the surface of the cross beam, through holes penetrate through the lifting lugs, and the through holes penetrate through the front face and the rear face of the lifting lugs;
the upper surface of the beam is fixedly provided with a rope groove, the rope groove is designed to be concave in the upper surface, the upper surface of the rope groove supports a steel wire rope, and the upper surface of the rope groove is provided with a rubber sheet.
Preferably, the cross beam is made of I-shaped steel, and the lifting lugs are welded with the cross beam.
Preferably, the front surface and the rear surface of the bottom of the lifting lug are welded with a right-angle edge of a right-angle plate, and the other right-angle edge of the right-angle plate is welded with the cross beam.
Preferably, two pairs of rope grooves are fixedly mounted on the upper surface of the cross beam, and two rope grooves are arranged in each pair and are symmetrically located on the left side and the right side of the lifting lug respectively.
