Foundation technique:
In the technique of adjusting the air gap on the large main drive continuous motor, it is often essential to use a jack that will repeatedly move the stator position. Because the motor foundation pit and the main motor bottom plate have same height, the jack includes no position support. Therefore, the jack erection problem should be solved and improved urgently. At present, the following two methods usually are used. One is to create a jack stopper and fix the stopper around the foundation pit with expansion bolts. The stator may be adjusted by supporting the jack for the stopper, but the installation and removal belonging to the baffle takes a lot of time. Affect the construction agenda and efficiency. The second would be to support the jack within the side of the base pit by obliquely pressing against the stator to complete the movement with the stator. However, due into the oblique pressure, the moving effect just isn't good. The jack usually slips off, which will damage the inspiration pit and the jack. The actual result is high cost along with low efficiency.
Technical recognition elements:
The bracket contains: a support plate, a stop plate and also a positioning plate; wherein the support plate lies on the top surface belonging to the foundation pit for supporting the jack; the stop plate and also the positioning plate are respectively put on the support plate The abutment plate along with the positioning plate are fixed at an angle with the support plate; the abutment plate as well as positioning plate are separated by the first preset distance; the support plate A adjusting member is provided on the jack for adjusting the axial direction from the jack; the adjusting new member, the positioning plate plus the abutting plate are separated by just a first preset distance plus a second preset distance, respectively.
