Abstract
The utility model relates to a rapid assembly device for a pulley block. At present, some fixed pulley devices of a hoisting machine are comparatively difficult to dismantle, as a result, work efficiency is low, the reinstallation and positioning of the dismantled fixed pulley devices are also troublesome, and labor and time are consumed. For this reason, the rapid assembly device for the pulley block comprises N fixed pulley devices spaced through spacer bushes, a pulley shaft and a pulley support device. The N fixed pulley devices are fixed on the pulley support device through the pulley shaft. The pulley support device comprises two upper supporting frame devices and a lower supporting frame device. The two upper supporting frame devices are connected with the lower supporting frame device through four bolts. The pulley shaft is mounted on the lower supporting frame device. The N fixed pulley devices are mounted on the pulley shaft. Locating round nuts with an anti-falling function are arranged on the two sides of the pulley shaft respectively. The rapid assembly device for the pulley block is simple in structure, scientific in design, convenient to use, and capable of realizing rapid installation, dismantling and fixation of the pulley block on the precondition that the pulley shaft is not dismantled or installed again, thereby greatly improving work efficiency.
Description
Technical field
The utility model belongs to the elevator machinery field, particularly a kind of assembly pulley quick-fitting device.
Background technology
At present, in elevator machinery, the 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 problems to be solved in the utility model is the above-mentioned defect that how to overcome prior art, and a kind of assembly pulley quick-fitting device is provided, and this assembly pulley quick-fitting device can realize that the quick peace of fixed pulley tears open fixingly, 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 the pulley bracket device by sheave shaft, the 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 the bracing frame lower device; On the bracing frame lower device, sheave shaft is installed, N fixed pulley is installed on sheave shaft; The 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 being fastenedly connected by bolt, the pulley support frame is combined by two parts, both can when sheave shaft is installed, avoid wearing the 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 be 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.
The utility model assembly pulley quick-fitting device, simple in structure, design science, easy to use, can be again under the precondition of dismounting sheave shaft, and the quick peace that realizes the fixed pulley group is torn open fixing, has greatly improved work efficiency.Have actual application value and promotional value preferably.
