Description

[0001] HAND-HELD TYPE APPARATUS FOR STUFFING PIPE [0002]

The present invention relates to a portable pipe fitting device for transportably supporting a pipe so as to fit the pipe in accordance with the direction and position of the pipe fitting hole of a block of a ship.

In general, ships are much larger than general buildings, are complicated in terms of process, and are manufactured through a drying process in which a large number of members and equipment are airtightly installed and assembled to secure structural stiffness and safety as float.

For example, ship construction work is carried out in parallel with hull construction, and pipe and iron products are manufactured according to the pre-designed process. Thereafter, block preliminary design work is carried out to construct block fronts to precisely install the fittings and pipes in the inside of the block of the hull.

Particularly, when the ship is dried, it is manufactured by joining the blocks, which are the parts of the ship, in the dock. When manufacturing each block, necessary pipes are combined inside or outside the block.

In this way, a large number of pipes are connected or installed inside the hull. When a pipe is inserted into a block by using a ceiling or a movable tower crane, safety of the operator is not ensured due to careless operation of the crane, There is a problem in that the operating rate of the apparatus is significantly reduced.

In addition, the pipe installed in the block of the hull has a pipe having a length of 10 meters or more. When such a pipe is installed, an operator may cause a musculoskeletal disease to the pipe operator when the pipe is handled in an unsafe position in a narrow area .

Further, in the process of inserting the pipe into the pipe hole or the like of the block, an apparatus for guiding and transporting the pipe in accordance with the position and direction of the pipe hole may be used.

The conventional pipe inserting apparatus disclosed in the patent document can not be used in a narrow space such as a pipe hole of a block or in an environment where it is difficult to move to the wheel of the main body.

Particularly, a pipe which is one kind of equipment of a ship is a heavy object which is caught by a roller of a seat base and is difficult to be transported because a protrusion such as a flange protrudes at a connecting portion of the pipe.

In this case, in the prior art, since the seat cushion is constructed so as to be movable up and down by the cylinder, only the seat cushion near the flange can be lowered among the plurality of seat cushions.

In this case, a spacing space may be formed between the pipe and the roller of the seat so that interference of the flange can be avoided. However, in a state where there is no supporting force due to the spacing space at a portion of the pipe above the spacing space, As the bending force acts downward at the site, a situation can be created in which the pipe can be lifted by the weight of the pipe.

Therefore, the operator quickly moves the pipe so as to allow the flange to pass without interfering with the roller when the pipe is moved by using the spacing space above the roller of the seat in the lowered state, and then to return the roller of the seat to the original state again , The seat must be raised.

However, from the viewpoint of the operator, there is no way to grasp the bending load or the roller permissible load of the pipe to be put back on the roller of the seat in the lowered state.

That is, since the operator lifts the seat and the roller in a moderately or simply manner corresponding to the height (position) of the pipe depending on experience, in this case, the load to be weighted on the roller of the raised seat, It is very difficult to apply a uniform supporting force to the pipe at the rollers of all the seatbelts.

In other words, in the prior art, the cylinder is operated to raise the seat back to the proper position to maintain the same height as the other seat, but the load applied to the roller of the raised seat is equal to the allowable load of the seat It is not known whether it is weak or strong.

If the supporting force between the rollers and the pipe of the elevated seat is relatively weak, it may be deflected downward with respect to the pipe conveying direction. On the other hand, if the supporting force is relatively strong, It is possible to exert an excessive supporting force capable of bending the pipe upwardly with respect to the pipe. As a result, the pipe transporting direction is deteriorated and the pipe can not be smoothly conveyed.

Also, the prior art pipe fitting apparatuses are used in plural and are disposed along the longitudinal direction of the pipe. By relying on the experience of the operator in arranging or arranging these pipe fitting apparatuses, precise alignment of the pipe fitting apparatus is performed .

In addition, since the conventional pipe inserting device has only a simple type of roller that can rotate in correspondence with the longitudinal direction of the pipe, when the pipe is rotated in the circumferential direction of the pipe to perform the pipe fitting, It can not be supported and transported.

In addition, since the conventional pipe fitting apparatus uses a hydraulic apparatus such as a cylinder, it is very difficult to carry, store and store in a portable manner, and due to its huge size, a pipe fitting operator can be attached or used in accordance with the site environment, It is necessary to provide means capable of being installed and moved, and capable of being installed and used even in a small space.

The height H of the moving bracket 540 can be adjusted so that the second lift plate 400 mounted on the moving bracket 540, the load gage 300, The lifting plate 200 and the wheel part 100 can be raised or lowered.

Since the moving bracket 540 is coupled to the first lifting plate 200 and the wheel unit 100 is coupled to the first lifting plate 200, (Displacement) is the displacement of the wheel part 100 or the displacement of the first lift plate 200.

Here, when the handle 510 is rotated (R), the displacement adjusting unit 500 can adjust the height H of the moving bracket 540, but even if the moving bracket 540 receives a downward load, 510 may have the structure of a lifting jacking device that is not reversed.

The base plate 600 is formed of a rectangular plate member having the same width, length and thickness as the first lifting plate 200 or the second lifting plate 400 and is coupled to the bottom of the displacement regulating unit 500 Can be. The base plate 600 may be further formed with a fastening bolt hole for fastening the fastening part 700 to the fixing bracket 550 and the fixing part 700 of the displacement adjusting part 500. For reference, when the bolt connection is not used, at least the upper surface intermediate position of the base plate 600 may be fixed by welding by the fixing bracket 550 of the displacement adjusting part 500.

In order to allow the fixing portion 700 to be replaced with a clamp member (not shown) corresponding to the shape of the hull for the hull block, the fixing portion 700 is bolted to both sides of the bottom of the base plate 600, May be connected to the upper portion of the casing.

On the other hand, the present embodiment can be used in a number of ways such as a plurality of portable pipe fitting apparatuses arranged in the longitudinal direction of the pipe.

In this case, the portable pipe fitting apparatus is used along the lengthwise direction of the pipe, i.e., in a line spaced apart. To facilitate such a spacing arrangement, the present embodiment includes a laser sighting device 800 ), Or a laser sighting device 800 'added to the second lifting plate 400. Using one of these laser sighting devices 800 and 800', the alignment between a plurality of portable pipe fitting devices It can be easily performed.

For example, the laser aiming device 800 is coupled to the base plate 600 in the direction of a short side (e.g., width direction) of the base plate 600 at an upper end of the base plate 600, And may be responsible for irradiating the laser beam.

Alternatively, the other laser sighting device 800 'may be coupled to the second lift plate 400 in the widthwise direction of the second lift plate 400 from the upper center of the second lift plate 400.

Here, the laser light may be formed in a line shape having a predetermined width. In addition, the installation position of the laser aiming device 800, 800 'may be provided at other positions of the components of the portable pipe fitting apparatus except for the above-mentioned position, as long as the pipe can be aligned.

FIG. 2 is an exploded perspective view of the load gauge unit shown in FIG. 1, and FIG. 3 is a perspective view illustrating a part of the load gauge unit shown in FIG.

2 and 3, the load gauge unit 300 includes a flange portion 311 having a plurality of bolt holes to be engaged with the bottom surface of the first lifting plate, And an outer housing 310 provided on the inner circumferential surface of the sliding hole 313. Here, the outer housing 310 may be a vertically-opened hollow structure.

The load gauge unit 300 has a step 321 corresponding to the stopper 312 formed at the upper edge of the seat hole 322 and a graduation point 324 indicated by the lower end surface 314 of the outer housing 310 323 may be formed on the outer circumferential surface and may include an inner housing 320 having a bolt hole 324 for engaging with the upper surface of the second lifting plate and inserted into the sliding hole 313. Here, the inner housing 320 is opened only at an upper portion of the inner housing 320, and the lower portion of the inner housing 320 may be a closed hollow structure.

The scale 323 is marked by the allowable load of the wheel corresponding to the elastic modulus of the elastic body 330 to be described later. The scale 323 is grasped in advance by experiment, and then the inner diameter of the inner housing 320 on the outer circumferential surface.

The load gauge unit 300 may include an elastic body 330 inserted in the seat hole 322 and having an elastic modulus corresponding to a wheel allowable load for supporting the pipe to be conveyed.

Here, the elastic body 330 may be constituted by a coil spring, a compression spring, or the like, but may be applied as a means capable of exerting an elastic force such as a hydraulic pressure method or a gas filling method.

When the load gage 300 is installed between the first lift plate 200 and the second lift plate 400 as shown in FIG. 1, the upper end of the elastic body 330 is connected to the first lift plate 200 And the lower end of the elastic body 330 can be brought into contact with the bottom surface of the seating hole 322. [

In this state, the elastic repulsive force generated when a load is applied and the elastic body 330 is compressed acts on the bottom surface of the first lifting plate 200 in a direction opposite to the direction in which the inner housing 320 is lifted Or vice versa, in the direction opposite to the direction in which the first plate 200 descends based on the bottom surface of the seating hole 322. [

1, 2, and 3, a method of operating the load gauge unit 300 will be described.

As described above, the operator can rotate the handle 510 of the displacement adjusting part 500 in a direction to raise the wheel 100, etc.

The height H of the moving bracket 540 can be adjusted by the displacement adjusting part 500 so that the wheel part 100 can be brought into contact with the bottom of the pipe. When the wheel 100 is in contact with or contacts the bottom of the pipe 100, the elastic member 300 may be provided with the wheel 100, the first lifting plate 200, the outer housing 310 of the load gage 300, Only the self-load of the device component can be applied to the elastic body 300. [

When the operator further rotates the handle 510 of the displacement adjusting part 500 in a direction to raise the wheel 100, the moving bracket 540 is moved to the second lift plate 400 and the inner housing 320, A load pushing upward is generated.

The upwardly pushed load can compress the elastic body 330 within a range that maintains an equilibrium with a load load (e.g., the load of the device component itself plus the load applied to the pipe) .

Due to this compression, the lower end surface 314 of the outer housing 310 indicates a scale 323 corresponding to the load load.

Here, the present embodiment is based on the assumption that a plurality of experiments for predicting the load load are premised. That is, through various load tests, various types of elastic bodies 330 are replaced on the basis of the same experimental use (experimental pipe) as the pipes used in the field, and the elastic modulus similar to the wheel allowable load of the wheel 100 It is possible to find the elastic body 300 having the above-mentioned elasticity. Accordingly, the magnitude of the load load capable of safely supporting the pipe can be grasped in advance. Further, the numerical value of the magnitude of the previously obtained load load can be informed to the operator at the piping work site through training.

Therefore, the worker at the piping work site confirms visually that the lower end surface 314 of the outer housing 310 indicates the scale 323, and visually confirms the numerical value of the load load for safely supporting the pipe in advance The scale 323 of the load load value known to the operator himself or herself is adjusted to the lower end of the outer housing 310 by adjusting the angle of rotation R of the handle 510 of the displacement adjusting part 500 appropriately, The surface 314 can be controlled to be pointed.

In this case, the load may be the same or very similar to the bearing force before the adjustment of the height H for the passage of the flange. As a result, once the wheel unit 100 is lowered and then raised again, It is possible to properly support the pipe and to prevent the directionality of the pipe transfer direction from being deteriorated beforehand, so that the pipe can be smoothly conveyed.

This will be further described with reference to FIG. 4 to FIG.

Figs. 4 to 7 are use state diagrams of the portable pipe fitting apparatus. Fig.

Referring to FIG. 4, a plurality of portable pipe fitting devices may be aligned in line with the bottom B (e.g., a steel plate of a block of a hull) of a pipe admission work site using a laser sighting device 800. The method of aligning using the laser sighting device 800 has been described above with reference to FIG. 1, and therefore can be omitted here. Of course, the portable pipe fitting devices may be aligned to a baseline (not shown) drawn by the tape measure.

Thereafter, the operator can rotate the switch lever 720 of each fixing portion 700 within a finite angle range, so that the casing 710 can be fixed to the floor B by the magnetic force.

The operator can also screw the pillar 910 of the outrigger 900 so that the bottom of the pillar 910 is brought into close contact with the bottom B so that the portable pipe fitting device can be prevented from being rolled over.

Further, the pipe P can be transported by using a pulling force of a plurality of worker's forces or a booster device or a crane around the pipe P, a chain hoist, or the like.

First, in the pipe feeding state, the height of all the wheel parts 100 is adjusted to the height corresponding to the fitting position of the pipe P as shown in FIG. The flange F of the pipe P may be caught by the wheel 100 and may be a catching jaw in view of the conveyance of the pipe P. In this case, since the wheel 100 is in contact with the outer peripheral surface of the pipe P, State.

In order to remove such anchoring jaw, the operator can lower the wheel part 100 of the portable pipe fitting device on the side of the upcoming flange (F).

The state of the wheel unit 100 thus lowered can be confirmed from FIG.

Referring to FIG. 5, for example, if three portable pipe fitting devices are spaced along the longitudinal direction of the bottom B, the height H1 of the displacement control part 500 of the second portable pipe fitting device The flange F of the pipe P does not interfere with the wheel portion 100 of the second portable pipe fitting device and the second flange F of the pipe P passes through the second portable pipe fitting device .

At this time, the rim wheel 112 of each wheel 100 can support the pipe F while being driven to rotate along the direction of transport of the pipe F, and if the pipe F is connected to the pipe F for fitting, The omni wheel 110 itself of the wheel assembly 100 rotates together with the pipe F so that the transfer and fitting operation of the pipe F can be easily performed.

Referring to Fig. 6, the flange F of the pipe P may pass through the spaced space above the wheel portion 100 of the second portable pipe fitting device.

In this case, the operator uses the displacement adjusting unit 500 to raise the wheel 100 so as to bring the wheel 100 into contact with the outer peripheral surface of the pipe P, (P) through the pipe (100).

7, the worker operates the handle (not shown) of the displacement regulating unit 500 until the lower end face 314 of the outer housing 310 indicates a scale 323 having a numerical value corresponding to a load load which is known in advance 510) and then stops the rotation of the handle 510.

In this case, as the proper supporting force corresponding to the load load is applied to the pipe P, the transport direction of the pipe P is not changed due to the height adjustment for avoiding the flange F, The conveying efficiency of the pipe P can be maintained and the bending deformation of the pipe P can be prevented in advance during the conveyance of the pipe P.

The wheel 100a according to the present application may include a conveying wheel 130 that is rotatable in the pipe conveying direction and spaced apart from each other and arranged obliquely to each other, A shaft 140 and a triangular support block 150 to which the support shaft 140 is coupled to support the support shaft 140 in a V-shape.

The support shafts 140 are coupled to one side slope and the other side slope of the triangular support block 150 so as to form a V shape so that the feed wheels 130 can stably support the bottom of the pipe in a V- .

Particularly, since the circumferential surface width W of the conveying wheel 130 is formed to be relatively larger than the diameter D of the conveying wheel 130, it is possible to stably support the heavy pipe, It is possible to prevent a phenomenon in which the conveying wheel 130 is released to the outside of the conveying wheel 130 in advance.

FIG. 9 is a perspective view of a portable pipe fitting apparatus according to another embodiment of the present invention, and FIG. 10 is a perspective view illustrating the portable pipe fitting apparatus and pipe shown in FIG.

Referring to FIG. 9, the portable pipe fitting apparatus according to another application example has a structure in which the fixing portion 700a is rotated at an angle of 90 degrees, as compared with the above embodiment (for example, FIG. 1) To the bottom of the base plate (600). In this case, since the switch lever 720 may protrude in the lateral direction of the portable pipe fitting device, interference with the structure at the site of use may be avoided.

In addition, the portable pipe insertion apparatus according to another application may further include a load gauge unit 300a between two load gauge units 300 between the first lift plate 200a and the second lift plate 400a And it is possible to stably support a pipe having a relatively large weight in comparison with the pipe described above.

In addition, the portable pipe fitting apparatus according to another application example may have a structure in which the triangular support block 150a may be coupled to the first lifting plate 200a in a state rotated at an angle of 90 degrees, as compared with the above application example (for example, have. At this time, the first lifting plate 200a according to another application example may be provided at both sides of the middle position of the first lifting plate 200a so as to provide the triangular supporting block 150a with the largest possible supporting area, And may further include an enlarged portion 290 protruding integrally.

The arrangement position of the pair of conveying wheels 130 of the wheel portion 100b is changed to be rotated by an angle of 90 degrees with respect to the direction of engagement of the triangular support block 150, So that the pipe P can be supported.

That is, the portable pipe fitting apparatus according to another application is disposed at the bottom B of the pipe filling operation site such that the longitudinal direction of the first lift plate 200a and the components positioned below the first lift plate 200a coincides with the extending direction of the pipe P Thereby avoiding interference with other protruding structures that may be present at the bottom B of the piping work site.

That is, the portable pipe fitting apparatus itself according to another application example is arranged coinciding with the extending direction of the pipe P, and only the feed wheel 130 of the wheel unit 100b rotates at an angle of 90 degrees with respect to the extending direction of the pipe So that it can be installed and used while avoiding the projections on the bottom of the pipe filling work site.
