Description

Hydraulic jockey Die for Preventing falling}

The present invention relates to a hydraulic jockey die for prevention of fall, and more particularly, to prevent the connection between the support and the piston part of the hydraulic jockey through the pipe guide to accommodate the piston part of the hydraulic jockey and the lower part of the support. And an anti-falling hydraulic jockey die configured to prevent falling accidents.

In general, during the construction of a ship, a hull structure such as a hull, a block, a deck, or a heavy structure (hereinafter referred to as a 'block') has a considerable weight and volume and is formed in various shapes. For this block work, several pin jigs are distributed under the block to distribute the load and work stably.

Such pin jigs are generally made uniform in height, and in the case of a curved block having an outer surface, a block level adjustment operation is performed using a separate hydraulic jockey.

1 is a schematic diagram showing a block level adjustment operation using a hydraulic jockey of the prior art. Referring to FIG. 1, a plurality of pin jigs 20 are distributed and disposed under a plane portion of the hull block 10.

In addition, the hydraulic jockey 40 is installed on the floor of the workshop for the level adjustment of the curved portion of the hull block 10, and the support 30 is installed between the hydraulic jockey 40 and the hull block 10.

As shown in FIG. 2, the hydraulic jockey 40 includes a cylinder cylinder part 41 and a piston part 43 whose length is protruded by the hydraulic pressure provided to the cylinder part 41. The lower end of the support 30 is mounted on the upper portion of the piston unit 43 is elevated together with the piston unit 43, thereby adjusting the level of the block.

However, the above-described prior art has a problem in that the head provided at the upper end of the support 30 is easily slipped from the inclined surface or curved surface of the block, so that the fall accident occurs frequently.

For example, when the center of gravity is disturbed due to the sliding during the lifting operation by the hydraulic jockey 40 as shown in FIG. 3, the piston part 43 is separated from the upper end of the support 30 while bending.

At this time, the support 30 and the hydraulic jockey 40 are bounced off by the load of the hull block 10 while hitting the surrounding structure or the worker, or a problem occurs, or the hull block 10 is seriously conducted. Can be.

In order to solve the problems of the prior art by providing an anti-falling hydraulic jockey die including a piston guide and a guide portion to accommodate the piston portion of the hydraulic jockey of the present invention, the piston part of the support and the hydraulic jockey which is a weak part. It is to prevent the break between and to prevent the occurrence of departure and fall accident.

According to one aspect of the invention, the first guide plate is seated cylinder portion of the hydraulic jockey; A second guide plate disposed above the cylinder portion spaced apart from the first guide plate; A connecting bar connecting the first guide plate and the second guide plate circumference; And a pipe guide part formed at the center of the second guide plate to accommodate a piston part of the hydraulic jockey and a portion of the lower end of the support. The hydraulic jockey die for preventing a fall can be provided.

In addition, a fixing clip part for fixing the cylinder part of the hydraulic jockey may be formed on the first guide plate.

In addition, the first guide plate and the second guide plate may be manufactured in a circular shape.

In addition, the second guide plate may be installed to slide through the support.

The present invention provides a fall prevention hydraulic jockey die including a pipe guide portion to accommodate the piston portion of the hydraulic jockey and a lower part of the support, thereby preventing the break between the support portion and the hydraulic jockey piston, which is a fragile portion, to prevent breakage and fall accident. It has the effect of preventing the occurrence.

Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings.

Figure 4 is a perspective view of the hydraulic jockey die for preventing falling in accordance with the present invention, Figure 5 is a front view of the hydraulic jockey die for preventing falling in accordance with the present invention.

4 and 5, the hydraulic jockey die for preventing falling according to the present invention includes a first guide plate 210, a second guide plate 220, a pipe guide part 230, and a connection bar 240. .

First, the first guide plate 210 in which the cylinder portion 141 of the hydraulic jockey 140 is seated is disclosed.

The first guide plate 210 is a base structure installed on the floor of the workplace, it is preferable to ensure a stable support by ensuring a wide contact with the bottom surface as wide as possible.

The structure for this may be provided in a disk shape or a square plate shape, such as the disk shape is shown in FIG.

In addition, a second guide plate 220 is installed above the cylinder part 141 spaced apart from the first guide plate 210.

The second guide plate 220 may have a structure opposite to the first guide plate 210, and may have a disc-like structure as shown in FIG. 4.

The first guide plate 210 and the second guide plate 220 are connected using a plurality of connection bars 240.

At this time, the connecting bar 240 is provided in a plurality of intervals along the outer circumference of the first guide plate 210 and the second guide plate 220, the second guide plate 220 is connected to the connection bar 240 Penetration) can be made to adjust the height.

In addition, a pipe guide 230 is installed at the center of the second guide plate 220. The pipe guide portion 230 serves to prevent the connecting portion of the hydraulic portion of the hydraulic portion 140 to be accommodated so that the lower portion of the piston portion 143 and the support 130 is bent.

At this time, as the piston part 143 of the hydraulic jockey 140 moves up and down, the second guide plate 220 and the pipe guide part 230 are lifted together, thereby connecting the piston part 143 to the support 130. Can always be located in the tube guide 230.

In addition, a fixing clip 250 for fixing the cylinder portion 141 of the hydraulic jockey 140 may be formed on the first guide plate 210.

In this case, the fixing clip 250 is connected to the cylinder portion 141 of the hydraulic jockey 140 to fix the hydraulic jack 145 for supplying the hydraulic pressure on the first guide plate 210.

Referring to the operation of the present invention having the above configuration is as follows.

First, the hydraulic jockey 140 is seated on the first guide plate 210. Then, the second guide plate 220 is coupled to the hydraulic jockey 140 above.

At this time, the second guide plate 220 is coupled to be elevated through the plurality of connecting bars 240, so that the piston portion 143 of the hydraulic jockey 140 in the pipe guide 230.

Then, the support 130 is installed so that the lower end of the support 130 is inserted into the pipe guide 230. Then, the hydraulic pressure is supplied to the cylinder portion 141 so that the piston portion 143 and the support 130 are lifted so that the block level adjustment work is performed.

As described above, the present invention provides a fall prevention hydraulic jockey die including a pipe guide portion to accommodate a piston part of the hydraulic jockey and a lower part of the support, thereby preventing bending between the support part and the piston part of the hydraulic jockey. This prevents departure and fall accidents.
