Abstract
The utility model provides a nuclear power plant personnel gate jacking dolly bearing change instrument platform, includes dull and stereotyped, supporting leg, rotatable supporting leg, wherein dull and stereotyped connection supporting leg, rotatable supporting leg of bottom installation of supporting leg. The number of the supporting legs is four. The height is adjusted by rotating the rotatable support legs.
Description
Technical Field
The invention belongs to the field of special maintenance tools, and particularly relates to a bearing replacing tool table for a jacking trolley of a personnel gate of a nuclear power plant.
Background
This personnel gate jacking dolly bearing change instrument platform is applicable to shell leakage monitoring system (EPP) personnel gate, emergent gate jacking dolly bearing change work, in personnel gate switch work during Fuqing nuclear power 2# unit overhaul, the cracked condition of dolly bearing (the unable operation of gate, the unable nuclear island of business turn over of personnel, restrict overhaul mainline work), when carrying out the bearing change, need wholly shift out the jacking dolly, because dolly automobile body weight is big, and can't hoist and mount during the change, can only lift the dolly from the door body by the manpower, very easily the landing leads to the staff injured when shifting out, therefore bearing change work can't in time be accomplished. Through on-site investigation and research, a bearing dismounting tool table is manufactured, and finally, the bearing fault of the gate jacking trolley is processed.
Through designing a gate jacking dolly bearing change instrument platform, the perfect jacking bearing trouble that appears during the unit up-and-down during overhaul has been solved, greatly improves work efficiency, and in time the recovery gate is available, reduces the restriction thread influence, guarantees personnel business turn over nuclear island.
Disclosure of Invention
The invention aims to: the utility model provides a nuclear power plant personnel gate jacking dolly bearing change instrument platform can guarantee equipment safety, improves work efficiency at maintenance work interval quick replacement jacking dolly bearing.
The technical scheme of the invention is as follows: the utility model provides a nuclear power plant personnel gate jacking dolly bearing change instrument platform, includes dull and stereotyped, supporting leg, rotatable supporting leg, wherein dull and stereotyped connection supporting leg, rotatable supporting leg of bottom installation of supporting leg.
The number of the supporting legs is four.
The height is adjusted by rotating the rotatable support legs.
The invention has the following remarkable effects: easy operation, portable, with low costs, practicality are high, and stability is good can not rock, can carry out jacking dolly bearing and change, can protect driving for overhaul gate switch.
(1) This jacking dolly bearing instrument platform operation is simple and easy: need not external power supply, directly can carry out jacking dolly bearing and change, do not have complicated control button and drive mechanism.
(2) This jacking dolly bearing tool table removes adjustably: the height of the tool table can be adjusted by rotating the supporting legs, and the tool table can be used on site.
(3) This jacking dolly bearing instrument platform can be convenient for solve jacking dolly bearing and damage the trouble, shortens the unit overhaul during the down stroke personnel gate unavailable time, accomplishes the bearing and changes rapidly, improves work efficiency, and guarantee personnel's safety business turn over nuclear island.
Drawings
FIG. 1 is a schematic view of the utility model of a tool table for replacing the bearing of the jacking trolley of the personnel gate of the nuclear power plant
FIG. 2 is the utility model discloses the personnel's gate jacking dolly bearing of nuclear power plant changes instrument platform and watches the picture
In the figure: 1 flat plate, 2 supporting legs and 3 rotatable supporting legs.
Detailed Description
The utility model provides a nuclear power plant personnel gate jacking dolly bearing change instrument platform, includes dull and stereotyped 1, supporting leg 2, rotatable supporting leg 3, wherein dull and stereotyped 1 connects supporting leg 2, and supporting leg 2 is total four, and rotatable supporting leg 3 is installed to the bottom of supporting leg 2, and through 3 height-adjusting of rotatable supporting leg of rotation.
When the bearing of the jacking trolley is replaced, the platform is used for replacing, and the specific operation method is
1. The height is adjusted to fit the site by rotating the rotatable support legs 3 to the rotatable support, at which time the tool table is ready for use.
2. The jacking trolley bearing of the personnel gate is transferred to the platform, and the replacement work can be carried out quickly.
3. According to the method, the jacking trolley bearing can be smoothly replaced, so that the purposes of ensuring the equipment safety, improving the working efficiency and reducing the operation cost of the power station are achieved.
This personnel gate jacking dolly bearing change instrument platform is applicable to shell leakage monitoring system (EPP) personnel gate, emergent gate jacking dolly bearing change work, in personnel gate switch work during Fuqing nuclear power 2# unit overhaul, the cracked condition of dolly bearing (the unable operation of gate, the unable nuclear island of business turn over of personnel, restrict overhaul mainline work), when carrying out the bearing change, need wholly shift out the jacking dolly, because dolly automobile body weight is big, and can't hoist and mount during the change, can only lift the dolly from the door body by the manpower, very easily the landing leads to the staff injured when shifting out, therefore bearing change work can't in time be accomplished.
