Abstract
The invention discloses a welding ball suitable for suspension bridge main cable wrapping wires according to welding conditions of the suspension bridge main cable wrapping wires at present. According to the technical scheme, the welding ball is characterized in that according to the outer diameters of the main cable wrapping wires, the welding depth and the welding area are calculated in cooperation with stressed conditions of the main cable wrapping wires at the 20 MPa pressure, the welding dosage is determined, the welding ball is accordingly made, and every two adjacent wrapping wires are welded. The welding ball for the suspension bridge main cable wrapping wires comprises, by mass, 1 part of iron powder, 1.5 parts of aluminum powder, 3 parts of iron oxide and 2 parts of copper oxide, and in order to enable the materials to generate a chemical reaction, more than 5% of igniting agents are further needed to be added. In order to bring convenience to field operation, the welding ball for the suspension bridge main cable wrapping wires is overall packaged in a ceramic type container, the igniting agents are arranged on the upper portion, the welding agents are arranged on the lower portion, and a metallic gasket is arranged at the bottom. Compared with the prior, the welding ball has the advantages of being high in welding speed and welding quality, free of a power source, high in wind resistance and suitable for complex and aerial working.
Description
Technical field
The present invention relates generally to bridge field, is mainly the welding that main rope of suspension bridge is wound around silk, relates in particular to the parallel welding between the adjacent winding steel wire of main push-towing rope.
Background technology
Suspension bridge is large as span, and moulding is exquisite, and application is at home more and more extensive, but main push-towing rope twines welding between silk as a difficult problem, perplexs for a long time the bridge construction person of China.Owing to twining a pulling force that is subject to 20MPa, current welding manner all can not meet its performance requirement, or twines silk fracture, or weld strength is inadequate, twines silk loosening, cannot meet design requirement.
Summary of the invention
The present invention is directed to current suspension bridge main rope winding welding situation, develop a kind of welding ball of applicable suspension bridge main rope winding.
Technology path of the present invention is: according to main push-towing rope, twine the external diameter of silk, in conjunction with the force-bearing situation of its 20MPa, calculate the depth of weld, bonding area, determine welding dosage, make thus welding ball, two adjacent twining between silk, weld.
The welding compound chemical formulation of welding ball main body of the present invention is: the ratio of iron powder, aluminium powder, iron oxide, cupric oxide is 1:1.5:3:2(quality), for making above-mentioned material generation chemical reaction, also need to add more than 5% detonator.
The dosage of welding ball of the present invention is calculate and draw according to the diameter of winding steel wire and force-bearing situation.
For ease of execute-in-place, welding ball of the present invention is encapsulated in the container of ceramic shape, detonator up, welding compound below, bottom is equipped with metallic gasket.
Compared with prior art, it is fast that main push-towing rope twines a speed of welding, and plumb joint quality is high, and without power supply, wind-proof performance is strong, is applicable to complicated, work high above the ground.
Accompanying drawing explanation: Fig. 1 is welding ball product schematic diagram.
The specific embodiment:
Main push-towing rope twines wire bond and connects ball and be comprised of content and overwrap, 1 capping for suspension bridge main rope winding welding ball, 2 ceramic cylinders for welding ball, 3 be pad, 4 for detonator, 5 is welding compound, 6 for welding runner mouth.In specific operation process, open capping, with the burning things which may cause a fire disaster powder 4 that will ignite, ignite, the rear heat producing of powder 4 burning that ignites will make welding compound 5 that a series of chemical reaction occurs, produce copper-iron-aluminium alloy solution, first alloy solution melts pad 3, then by 6 pairs of adjacent winding steel wire of runner, welds, thereby completes whole welding process.
