Embodiment 1

[0036] An embodiment of the invention provides a heating device for a super-large pulley assembly. see figure 1 and Figure 4 , the heating device comprises a first heating belt 7 and a second heating belt 10, the areas of the first heating belt 7 and the second heating belt 10 are larger than the super large pulley assembly pulley 66 (see Figure 4 ), the first heating belt 7 and the second heating belt 10 are placed relatively parallel with a certain gap 100 . The hub inner hole is suitable for being placed in the gap 100 between the first heating belt 7 and the second heating belt 10, and the heating device also includes controlling the heating of the first heating belt 7 and the second heating belt 10, so as to The first heating belt 7 and the second heating belt 10 are both electrically connected to the control unit 5 for making the expansion of the inner hole of the hub reach the standard expansion.

[0037] It can be seen from the above technical solution that a para...

Embodiment 2

[0056] An embodiment of the invention provides a method for assembling a pulley assembly. see Figure 5 , the method includes the following steps:

[0057] Step S101, providing a first heating belt and a second heating belt, wherein the areas of the first heating belt and the second heating belt are larger than the area of ​​the hub inner hole of the pulley of the super-large pulley assembly;

[0058] Step S102, placing the hub inner hole of the pulley of the super-large pulley assembly in the parallel gap between the first heating belt and the second heating belt;

[0059] Step S103, using the first heating belt and the second heating belt to heat the inner hole of the hub, so that the inner hole of the hub reaches a standard expansion;

[0060] Step S104, inserting the pulley shaft assembly of the super-large pulley assembly into the inner hole of the hub, so as to assemble the pulley shaft assembly and the pulley together.

[0061] It can be seen from the above technical...

Abstract

The invention discloses a heating device and an assembling method for a super-sized pulley component, and belongs to the technical field of super-sized pulley components. The heating device comprises a first heating tape and a second heating tape, wherein the area of each of the first and second heating tapes is larger than that of a hub inner hole of a pulley of the super-sized pulley component; the first and second heating tapes are arranged in parallel with a certain gap; the hub inner hole is applicably formed in the gap between the first and second heating tapes. The heating device also comprises a control unit for controlling the heating of the first and second heating tapes to enable the expansion of the hub inner hole to reach standard expansion, wherein the first and second heating tapes are electrically connected with the control unit. According to the heating device and the assembling method, the hub inner hole of the pulley of the super-sized pulley component is independently heated, and a main body part of the pulley is out of a heating range, so that influence on the quality of the main body part of the pulley is slight, and a few energy sources are consumed by heating.

Description

technical field [0001] The invention relates to the technical field of super-large pulley assemblies, in particular to a heating device and an assembly method for super-large pulley assemblies. Background technique [0002] The Three Gorges Project is one of the largest water conservancy projects in my country and even in the world at present, and the pulley assembly is an important part in the transmission device of the Three Gorges ship lift. Because the transmission device of the Three Gorges ship lift is very large, correspondingly, the size of the pulley assembly is huge, specifically: the outer diameter of the pulley is more than 5 meters, and the inner hole of the pulley hub is more than 600 mm. Such a pulley assembly is an oversized pulley assembly. [0003] At present, when assembling super-large pulley assemblies with the above-mentioned dimensions, the overall heating method is generally adopted. This integral heating method requires a super-large heating furnace...
