Abstract
The invention relates to a quick assembly device of a pulley set. At preset, several fixed pulley devices in lifting machines are more difficult to be disassembled, so that the working efficiency is lower, the reinstallation in place is also troublesome after the disassembly, and the labor and time are wasted. Therefore, the quick assembly device of the pulley set comprises N fixed pulley devices divided by spacer bushes, a pulley shaft and a pulley bracket device, wherein the N fixed pulley devices are fixed on the pulley bracket device through the pulley shaft; the pulley bracket device consists of two support frame upper devices and a support frame lower device; the two support frame upper devices and the support frame lower device are connected through four bolts; the pulley shaft is mounted on the support frame lower device; the N fixed pulley devices are mounted on the pulley shaft; and positioning round nuts with an anti-dropping effect are arranged at the two sides of the pulley shaft. The quick assembly device of the pulley set has the advantages of simple structure, scientific design and convenience for use; and under the precondition of not disassembling the pulley shaft again, the quick disassembly, assembly and fixation of the pulley set are realized, and the working efficiency is largely improved.
Description
Technical field
The invention belongs to elevator machinery field, particularly a kind of assembly pulley quick-fitting device.
Background technology
At present, in elevator machinery, fixed pulley majority can not freely be dismantled; In addition, some fixed pulley removes more difficult, and labourer's intensity is larger, and work efficiency is lower, and after these fixed pulley dismountings, reinstalls in place also pretty troublesome, time-consuming.
Summary of the invention
The technical problem to be solved in the present invention is the above-mentioned defect that how to overcome prior art, and a kind of assembly pulley quick-fitting device is provided, and the quick peace that this assembly pulley quick-fitting device can be realized fixed pulley is torn open fixing, has greatly improved work efficiency.
For solving the problems of the technologies described above, this assembly pulley quick-fitting device, comprise N the fixed pulley, sheave shaft and the pulley bracket device that by spacer, separate, N fixed pulley is fixed on pulley bracket device by sheave shaft, pulley bracket device comprises two bracing frame upper units and bracing frame lower device, and two bracing frame upper units are connected by four bolts with bracing frame lower device; On bracing frame lower device, sheave shaft is installed, N fixed pulley is installed on sheave shaft; Sheave shaft both sides are equipped with the setting circle nut of tool anticreep effect.
So design, bracing frame upper unit and bracing frame lower device are realized and being fastenedly connected by bolt, pulley support frame is combined by two parts, both can when sheave shaft is installed, avoid wearing axle difficulty because of what Mismachining tolerance caused, reinstalls trouble in place after can also solving dismounting simultaneously.
As optimization, pulley bracket device inside is provided with N-2 the fixed pulley being arranged on sheave shaft, and pulley bracket device both sides are provided with 2 fixed pulleys that are arranged on sheave shaft.So design.
As optimization, fixed pulley is 5.
Assembly pulley quick-fitting device of the present invention, simple in structure, design science, easy to use, can be again under the precondition of dismounting sheave shaft, and the quick peace that realizes fixed pulley group is torn open fixing, has greatly improved work efficiency.There is good actual application value and promotional value.
