Abstract
The invention provides an auxiliary installation mechanism for a large nut. The auxiliary installation mechanism for the large nut is characterized by comprising a supporting block, a supporting hydraulic cylinder rod, a supporting hydraulic cylinder piston, a supporting hydraulic cylinder body, a threaded lead screw, a large nut lifting hook, a lead screw lifting hook and a thrusting nut. The supporting hydraulic cylinder body is sleeved on the threaded lead screw. One end of the supporting hydraulic cylinder rod extends into the supporting hydraulic cylinder body to form a movable hydraulic cylinder structure together with the supporting hydraulic cylinder body. One end, extending out of the supporting hydraulic cylinder body, of the supporting hydraulic cylinder rod is provided with the supporting block. The end, extending into the supporting hydraulic cylinder body, of the supporting hydraulic cylinder rod is connected with the supporting hydraulic cylinder piston inside the supporting hydraulic cylinder body. The thrusting nut is installed at the non-screwing end of the threaded lead screw and tightly abuts against the supporting hydraulic cylinder body. According to the auxiliary installation mechanism for the large nut, due to the fact that a small threaded hole or a taper hole is formed in the shaft which the nut is installed on, the large nut can center more easily when being installed. By means of the threaded lead screw, the nut can be screwed in more easily when being installed. Being supported by a hydraulic cylinder, the auxiliary installation mechanism for the large nut is simple and convenient to operate.

Advantage and effect:
The invention provides the auxiliary installing mechanism of a kind of large-scale nut, comprising: back-up block, supporting cylinder bar, supporting cylinder piston, support hydraulic pressure cylinder body, threaded screw rod, spanner, suspending hook and pushnut.
The invention has the beneficial effects as follows:
(1) the present invention is owing to having minor thread hole or bellmouth on the axle of mounting nuts, easier centering when big nut is installed;
(2) the present invention adopts threaded screw rod, easier precession in the installation process of nut;
(3) the present invention adopts hydraulic cylinder to support, and is simple to operation.
Description of drawings:
Fig. 1 is the radial section schematic diagram of the auxiliary installing mechanism of large-scale nut of the present invention;
Fig. 2 is the lateral cross schematic diagram of the auxiliary installing mechanism of large-scale nut;
Fig. 3 is the structural representation of the pushnut of the auxiliary installing mechanism of large-scale nut.
The specific embodiment:The present invention will be further described below in conjunction with accompanying drawing:
as shown in Figure 1, the invention provides the auxiliary installing mechanism of a kind of big nut, this mechanism comprises back-up block 1, supporting cylinder bar 2, supporting cylinder piston 3, support hydraulic pressure cylinder body 4, threaded screw rod 5, the axle 8 of mounting nuts, big nut suspension hook 9, leading screw suspension hook 10 and pushnut 11, support hydraulic pressure cylinder body 4 is enclosed within on threaded screw rod 5, one end of supporting cylinder bar 2 puts in support hydraulic pressure cylinder body 4 and the hydraulic cylinder structure of support hydraulic pressure cylinder body 4 formation activities, the end that supporting cylinder bar 2 stretches out support hydraulic pressure cylinder body 4 arranges back-up block 1, the interior supporting cylinder piston 3 of an end and support hydraulic pressure cylinder body 4 that supporting cylinder bar 2 puts in support hydraulic pressure cylinder body 4 is connected, pushnut 11 is arranged on the non-screw terminal of threaded screw rod 5, and near support hydraulic pressure cylinder body 4.Being interpreted as of the non-screw terminal of so-called threaded screw rod 5: threaded screw rod 5 has an end to need in the axle 8 of precession mounting nuts when using, and this section becomes screw terminal, becomes non-screw terminal and the other end is corresponding with it.
The contact site matcoveredn of the outer end of back-up block 1 and big nut 6 prevents the screw thread injury of 1 pair of big nut 6 of back-up block.
