Background technique

In mechanical equipment, there are many parts installed on the shaft, such as centrifugal fan impeller and circulating fan impeller. Some of these parts are located in the box and pipes, and are limited by the operating space. After the pipes need to be removed, ordinary pullers can be used to remove such parts that need maintenance, repair, and replacement, which is time-consuming and labor-intensive. There are also some components with large structural size and quality, which may cause potential safety hazards of the fan impeller slipping during disassembly. Moreover, when installing the above components, due to the small operating space, only the traditional knocking method can be used, which often causes impact damage to the end face of the impeller shaft disk, and at the same time, knocking has a negative impact on the transmission bearing, which is not conducive to the guarantee of installation and fit accuracy.

The upper and lower ends of the connection between the screw rod and the fixed hoop and the fixed block are fixed with bolts, and the ejector rod is screwed to the fixed block. The installation pressing block is detachably connected with the screw rod.

As a preference, both the fixed block and the fixed hoop are provided with more than two waist-shaped holes, the screw goes through the waist-shaped holes, the head of the ejector rod is a hexagonal square head, and the ejector rod It runs through the middle of the fixed block and is on the coaxial line with the center of the fixed hoop.

Preferably, it includes an arc-shaped support plate and a support block, the arc-shaped support plate is located under the fan impeller, the support block is located under the arc-shaped support plate, and is fixed with bolts between the arc-shaped support plate.

Preferably, the mounting pressure block is screwed to the screw rod, and the mounting pressure block is provided with a threaded hole, and the length of the threaded hole is 2/3 of the thickness of the mounting pressure block.

It adopts double-screw guide and adjustable fixed hoop device, which has the characteristics of balanced force and large adapting range, and can extend the disassembly operation to the outside of the box and pipeline inspection door, so that the disassembly operation of parts is time-saving and convenient. Save effort.

The beneficial effects of the utility model are as follows: 1. The original 4 people who use tooling to disassemble and install the fan impeller are reduced to 2 people, and the 2 people cooperate, the operation is simple, the manpower input is reduced, and the maintenance operation time is reduced from the original 4 hours It takes about 1 hour to improve work efficiency; 2. When disassembling and installing the fan impeller, due to the protective effect of the arc-shaped support plate, it can avoid the impeller slipping and cause personal injury or damage to the impeller, and improve the operation safety; 3. Use tooling to disassemble the fan The impeller avoids damage to the impeller by ordinary pullers and the difficulty of drawing the inner ring of the bearing; 4. Use tooling to install the fan impeller to avoid damage to the impeller, bearing and fan impeller shaft caused by hitting the impeller with a copper rod.
