Bounce occurs for cord, so as to usually cause steel wire rope to take off groove at amplitude variation trolley.As do not found in time, steel wire may result in
Restrict improper inordinate wear, rope-broken accident even occurs, caused a hidden trouble to safety in production and bring unnecessary economic loss.
The catch pin type groove separation preventing device that derrick crane assembly pulley is generally installed at present.The shortcomings that this device is present：1、
Catch pin type groove separation preventing device can only take off caused by anti-steel wire rope vertical jitter groove and impact for a long time it is yielding, 2, steel wire can not be prevented
Rope acutely rocks the job-hopping of caused side force.It is therefore desirable to this case is improved.Need a kind of new scheme
Solves above-mentioned technical problem.
Utility model content
The purpose of this utility model is to provide a kind of car rope groove-jumping-preventing device, to solve catch pin type groove separation preventing device
Yielding technical problem is impacted for a long time；And solving prior art can not prevent steel wire rope from acutely rocking caused side force and jumping
The technical problem of groove.
To achieve the above object, the utility model adopts the following technical scheme that：
A kind of car rope groove-jumping-preventing device, including pulley pack support and pulley, it is characterised in that：The assembly pulley branch
Frame includes two cross-braces be arrangeding in parallel and two vertical supportings be arrangeding in parallel, and two vertical supportings are fixed on two
Between root cross-brace, a short support of transverse direction is additionally provided between two vertical supportings, by two vertical supportings it
Between space be divided into two compartments；The pulley includes two groups of assembly pulleys, and two groups of assembly pulleys are separately fixed in two compartments,
Between the assembly pulley is fixed on two vertical supportings by pulley spindle, the pulley spindle is vertical with the vertical supporting of both sides solid
It is fixed, be provided with vertical supporting plate on the both sides of the assembly pulley, vertical supporting, between the vertical supporting plate, assembly pulley it is upper
Side is provided with lever, and the lever is provided with nylon wheel, and the nylon wheel is several, between pulley and lever and pulley and cunning
Between wheel.
It is further preferred that the assembly pulley includes two pulleys being arranged side by side.
Further, the cross-brace is made up of channel-section steel, two channel-section steel back cord two cross-braces of relative composition.
Further, the vertical supporting is made up of channel-section steel, two channel-section steel back cord two vertical supportings of relative composition.
In addition, the pulley spindle is fixed after passing through the preformed hole on the vertical supporting of both sides with bolt with vertical supporting.
It is further preferred that the number of the nylon wheel and the pulley number of assembly pulley are adapted.
The utility model has the characteristics that and beneficial effect compared with prior art：
The utility model overall construction design is ingenious, easy to operate, securely and reliably, convenient disassembly；The utility model can have
Effect prevents from taking off groove accident caused by steel wire rope vertical jitter, more effectively solves steel wire rope and asked by yielding technology is impacted for a long time
Topic；Pulley in the utility model is easily changed with nylon wheel, and manufacturing cost is low, adds the security of integral device, is reduced
Maintenance cost.
The utility model has the characteristics that safety, is applicable, and has popularization and practical value well, after extensive popularization and application
Good economic benefit can be produced.
