Description
Technical field
The present invention relates to a kind of insulation suspension hook assembly pulley device, be particularly useful for electrolytic cell and concentrate overhaul to carry the special insulation suspension hook assembly pulley device of overhead traveling crane.
Background technology
The repair method of electrolytic cell is generally after electrolytic cell has a power failure cooling, carries out tearing a series of service works such as groove, pot shell repairing, brickwork and superstructure installation open in original place, completes an electrolytic cell maintenance process and about needs about 50 days; Expansion is improved constantly along with electrolytic aluminium factory production scale and electrolysis grooved, the repairing work load of electrolytic cell is also increasing, this in-situ trouble method not only the repairing time long, affect electrolytic aluminium output, and cause environmental pollution, the working condition of workman is poor, and potential safety hazard is many, and electrolytic cell repairing quality cannot ensure; It is visual plant in movement system that electrolytic cell concentrates overhaul to carry overhead traveling crane, because of its need in potroom handling electrolytic bath shell, require that its suspension hook group has insulating properties.A kind of in existing suspension hook group technique is adopted by securing member felt pad and insulation sleeve to be surrounded the object making it to reach insulation, also has a kind of nylon pulley that adopts to realize insulation.Front kind of technology insulating point is too much, and make installation and overhaul more complicated, add the labour intensity of workman, rear kind of technology manufacturing cost is too high; Again because carrying overhead traveling crane will carry out long-distance transportation with electrolytic bath shell, walk to stop easily to cause in process and hang thing and rock, so require that suspension hook has certain anti-shake function.
Summary of the invention
For solving the problems of the technologies described above, the invention provides the assembly pulley device of a kind of electrolytic cell carrying overhead traveling crane special isolation suspension hook.Concrete scheme is as follows:
A kind of insulation suspension hook assembly pulley device, comprise suspension hook, lifting beam with hook, suspension hook frame plate, hook nut, pulley, described suspension hook frame plate arranges lifting beam with hook, described suspension hook is fixed on described lifting beam with hook by described hook nut; Described lifting beam with hook is fixed on suspension hook frame plate by an insulation assembly; The pulley spindle of described pulley is fixed on suspension hook frame plate by No. two insulation assemblies; The two ends of lifting beam with hook gudgeon are provided with rubber block, rubber block coordinates with the positioning runner arranged bottom main carriage, when lifting hook pulley group rises to highest point, rubber block slips in the positioning runner bottom main carriage, described lifting beam with hook is fixedly installed reinforcing ring, described reinforcing ring is arranged on insulation sleeve cylindrical, between the outside that described reinforcing ring is arranged on suspension hook frame plate and rubber block.
A described insulation assembly comprises insulation sleeve and felt pad, and described insulation sleeve is arranged between gudgeon and suspension hook frame plate; Described felt pad is arranged between lifting beam with hook and suspension hook frame plate.
Described No. two insulation assemblies comprise insulation sleeve and felt pad, and described insulation sleeve is arranged between pulley spindle and suspension hook frame plate, and described felt pad is arranged between pulley and suspension hook frame plate.
Described pulley is 4, and every two is one group.
Advantageous effect of the present invention: by an insulation assembly and No. two insulation assemblies and rubber block, not only make between suspension hook and pulley, to define twice insulation, ensure that the security of workman when potroom hoisting heavy, and make the positioning runner acting in conjunction bottom lifting hook pulley group and main carriage realize hanging the stability of thing in handling process; Owing to arranging reinforcing ring 15, lifting surface area strengthens, and reduces pressure, is not only conducive to protecting insulation sleeve 11, and adds service life and the security of lifting hook pulley group.

Detailed description of the invention
Below embodiments of the invention are described in detail by reference to the accompanying drawings, but protection scope of the present invention not limit by embodiment.
As shown in Figures 1 to 4, suspension hook assembly pulley device is insulated by a suspension hook 1, two suspension hook frame plates 2, a lifting beam with hook 3, hook nut 4 and four pulleys, 5, two pulley spindles 8, the compositions such as lifting beam with hook end block 7, insulation assembly 6 and No. two insulation assemblies 9.
Suspension hook 1 is installed on lifting beam with hook 3 by hook nut 4, and the gudgeon 301 of lifting beam with hook 3 is arranged on suspension hook frame plate 2 by an insulation assembly 6, realizes the insulation of suspension hook 1 and suspension hook frame plate 2; Pulley 5 is respectively installed on two pulley spindles 8, and pulley spindle 8 is arranged on suspension hook frame plate 2 by No. two insulation assemblies 9, realizes the insulation of pulley 5 and suspension hook frame plate 2, thus realizes insulating from suspension hook 1 to the twice of pulley 5; The two ends of lifting beam with hook 3 gudgeon are provided with rubber block 7, and its effect is when lifting hook pulley group rises to highest point, and rubber block 7 slips in the positioning runner 12 bottom main carriage 13, thus realize hanging the stable of thing in handling process.
A described insulation assembly 6 comprises insulation sleeve 11 and felt pad 10, and described insulation sleeve 11 is arranged between gudgeon 301 and suspension hook frame plate 2; Described felt pad 10 is arranged between lifting beam with hook 3 and suspension hook frame plate 2;
Described No. two insulation assemblies 9 comprise insulation sleeve 11 and felt pad 10, and described insulation sleeve 11 is arranged between pulley spindle 8 and suspension hook frame plate 2, and described felt pad 10 is arranged between pulley 5 and suspension hook frame plate 2; Described insulation sleeve 11 is for realizing radial insulation, and described felt pad is used for realizing axial dielectric;
For solving because stress concentrates brought insulation sleeve to damage in hoisting process, described lifting beam with hook 3 is fixedly installed reinforcing ring 15, and described reinforcing ring 15 is arranged on insulation sleeve 11 cylindrical.
Principle of the present invention is as follows:
By an insulation assembly 6 and No. two insulation assemblies 9, suspension hook 1 is made to be arranged between two suspension hook frame plates 2, form insulation between suspension hook frame plate 2 and pulley 5, thus make whole lifting hook pulley group have twice insulation, ensure that the security of workman when potroom hoisting heavy.The rubber block 7 being fixed on lifting beam with hook 3 two ends can realize hanging the stability of thing in handling process with the positioning runner bottom main carriage jointly, and realizes the secondary insulating of suspension hook 1 and dolly 13.Owing to arranging reinforcing ring 15, lifting surface area strengthens, and reduces pressure, is not only conducive to protecting insulation sleeve 11, and adds service life and the security of lifting hook pulley group.
