Description

Lifting device for supplementary artifical polishing of nuclear power return bend internal surface

Technical Field

The utility model belongs to nuclear power return bend field of making, concretely relates to supplementary artifical elevating gear who polishes of nuclear power return bend internal surface.

Background

After a nuclear power pipeline bent pipe is bent and formed, the inner surface and the outer surface of the bent pipe need to be polished, and the position of the bent pipe needs to be continuously adjusted in the polishing process. The outer surface is easier to grind, but the inner surface is more limited in position, so that the operation is more difficult within 180 degrees of the inner surface, and the grinding is troublesome and labor-consuming.

The general operation is to set up a platform for a grinding worker in advance and let the worker stand on the platform to operate. Or a forklift is used for lifting the worker to a proper height, and the worker stands on the fork of the forklift to operate. The first method is troublesome and labor-consuming, the platform needs to be built in advance each time, and the height of the platform is not fixed due to the fact that the height of the bent pipe is not fixed. The second solution requires a long time to occupy the forklift and is unsafe to operate while standing on the forklift. Therefore, the conventional method cannot realize labor-saving and convenient inner surface polishing of the nuclear power bent pipe.

Disclosure of Invention

The utility model aims at providing an artifical elevating gear who polishes of supplementary nuclear power return bend internal surface has realized the internal surface of not co-altitude nuclear power return bend and has polished, also convenient and swift more.

The purpose of the utility model is realized through the following technical scheme:

the utility model provides an artifical elevating gear who polishes of supplementary nuclear power return bend internal surface, includes lift platform 5 and cuboid frame 3, is located and installs lift loop wheel machine 4 on two relative horizontal poles on 3 tops of frame, 5 fixed connection of lift platform on lift loop wheel machine 4's wire rope one end lifting hook, the pole of the side on frame 1 on install cat ladder 6, the lower part of frame 4 install four auxiliary supporting legs 4.

As a more excellent technical scheme of the utility model, lift platform 5 on be fixed with security fence 12.

As a more preferable technical solution of the present invention, the frame 1 is fixedly connected with a reinforcing beam 11.

As a more excellent technical proposal of the utility model, the lifting crane 4 is a pulley elevator.

As a more excellent technical scheme of the utility model, the frame 1 bottom stabilizer blade on be connected with fixed plate 13.

As a more preferable technical solution of the present invention, the top end of the frame 1 is fixedly connected with a hanging ring 1 for placing a hanging hook.

The beneficial effects are as follows:

the utility model discloses a not polishing of nuclear power return bend of co-altitude is realized to lift platform's position. The lifting platform is suspended on a cross beam at the top of the platform frame through a steel wire rope, and a lifter is arranged in the middle of the steel wire rope. The lifting platform is basket-shaped, the height of the platform can be adjusted through the lifter, and the lifting platform is suitable for polishing the inner surfaces of nuclear power bent pipes with different heights.

FIG. 2 is a schematic view of the working state of the lifting device for assisting manual polishing of the inner surface of the nuclear power elbow pipe;

wherein: 1-lifting point, 2-platform suspension point, 3-platform frame, 4-lifter, 5-lifting platform, 6-ladder stand, 7 auxiliary supporting legs, 8-nuclear power bent pipe, 9-hanging strip, 10-crown block lifting hook, 11-reinforcing beam, 12-safety fence and 13-fixing plate.

Detailed Description

The present invention will be further explained with reference to the accompanying drawings.

As shown in fig. 1 and 2, the utility model provides an artifical elevating gear who polishes of supplementary nuclear power return bend internal surface, including lift platform 5 and cuboid frame 3, be located and install lift loop wheel machine 4 on two relative horizontal poles on frame 3 top, lift platform 5 fixed connection on lift loop wheel machine 4's wire rope one end lifting hook, frame 1 on the pole of side on install cat ladder 6, frame 4's lower part install four auxiliary support legs 4.

The working process of the utility model is as follows:

firstly, a straight pipe section of the nuclear power elbow 8, the inner surface of which needs to be polished, is lifted to be horizontal, and the other end of the nuclear power elbow is well cushioned by a batten on the ground, so that the port is prevented from being damaged. Then standing the platform frame 3 on the edge of a pipe orifice of the nuclear power bent pipe 8, and opening the auxiliary supporting legs 7 to stabilize the frame; the operator climbs up the lifting platform 5 from the ladder stand 6, adjusts the height of the platform through the manual adjustment lifter, so that the platform is suitable for polishing operation, and the operator can climb down to the ground from the ladder stand 6 when polishing is interrupted. The platform suspension point 2 of the lifter connected with the frame is positioned in the middle of two opposite cross rods at the top end of the frame 3. The utility model discloses can adjust the internal surface that lift platform height was applicable to the return bend of co-altitude not through the s riser and polish.
