Specific embodiment
The embodiments of the present invention is described further with reference to the accompanying drawing.
Fig. 1~5 are please referred to, large-scale hydroelectric generator rotor lifting plate workbench, it includes platform board 13, institute's platform The surface in bar region 2 and ring region 3 of converging is arranged in plate 13, and the platform board 13 is fixed in japanese character frame 12, institute It states japanese character frame 12 to be welded and fixed by platform column 9 and platform brace 11, the platform column 9 and platform brace 11 It being weldingly fixed on H-type frame 6, the side opposite with platform column 9 is welded with ladder column 4 on the H-type frame 6, It is welded on the ladder column 4 and steps on rank 401 and ladder rails 402;All pacify on the ladder column 4 and platform column 9 Supporting mechanism is adjusted equipped with screw rod.Platform can be prevented in the movement of generator radial direction, work by using above-mentioned workbench Make platform prevents platform mobile in generator circumferencial direction using the positioning key on upper spider and out frame bindiny mechanism, work Puller bolt on platform can hold out against in opposite directions the stud in upper spider and out frame bindiny mechanism on same straight line, prevent Workbench is swung, while being also capable of fixing the effect of entire workbench.
Further, the platform board 13 is less than the diameter in bar region 2 along the inside spread length of rotor radial after fixation To length.
Further, seat belt hanger 8 is welded in the top sidewall of the platform column 9.Pass through the safety belt Hook 8 can easily hook safety belt.It ensure that the safety in operation process.
Further, column is welded between the platform column 9 step on rank 10.10 energy of rank is stepped on by the column It is enough conveniently to enter on platform board 13.
Further, the H-type frame 6 is placed in upper spider when small-sized workbench is installed and connect machine with out frame On structure 15.
Further, the top of the H-type frame 6 is provided with arc-shaped handrail 7, and the arc-shaped handrail 7 is fixed on flat On platform column 9 and ladder rails 402.
Further, it includes the spiral shell being fixed on 4 side wall of platform column 9 and ladder column that the screw rod, which adjusts supporting mechanism, Mother 14 is fitted on the nut 14 by screw-driven and holds out against screw rod 5, and described one end for holding out against screw rod 5 is equipped with handle Hand 501, the other end are equipped with arc cap 502, the arc cap 502 and the 16 end face phase of stud for being fixed on 1 top of out frame Cooperation.It holds out against screw rod 5 to be mainly used for supporting small-sized workbench, prevents small-sized workbench from swinging, while can also play fixation The effect of entire small-sized workbench.
Further, the arc cap 502 uses nylon material, and front end is arc.Reduce the friction of contact surface, to prevent Hold out against the paint that screw rod destroys on upper spider and the stud 16 of out frame bindiny mechanism 15.
Further, the H-type frame 6 is justified by upper spider with the positioning key 17 in out frame bindiny mechanism 15 Circumferential direction limit.Workbench, which is inserted in upper spider and the mounting means of out frame bindiny mechanism 15, can prevent platform from generating electricity Machine radial direction is mobile.
The course of work and working principle of the utility model:
Structural principle: small-sized workbench is inserted in upper spider and out frame bindiny mechanism, this structure energy of platform Prevent platform mobile in generator radial direction.Small-sized workbench utilizes the positioning on upper spider and out frame bindiny mechanism Key prevents platform mobile in generator circumferencial direction.Puller bolt on small-sized workbench can push up in opposite directions on same straight line Stud on tight upper spider and out frame bindiny mechanism, prevents small-sized workbench from swinging, while being also capable of fixing entire small-sized The effect of workbench.
Mounting means: small-sized workbench is sling using hanging device and is inserted in upper spider and out frame bindiny mechanism On, puller bolt is operated, contacts two opposite puller bolts with upper spider with the stud of out frame bindiny mechanism respectively In place.Small-sized workbench is installed on each upper spider and out frame bindiny mechanism.
Usage mode: plate working personnel are from out frame through ladder, upper spider and out frame bindiny mechanism Top, column step on rank and reach platform board, and plate work can be carried out after fastening seat belts and fixing.In upper and lower ladder Temporarily safety belt, which can be hung over, ensures safety on handrail.
Above-described embodiment is used to illustrate the utility model, rather than limits the utility model, practical at this In novel spirit and scope of protection of the claims, to any modifications and changes that the utility model is made, this reality is both fallen within With novel protection scope.
