Description

Welding system of pipe fittings and pipes

The present invention relates to a welding system and a method for welding seams and pipes, and more particularly, it is possible to conveniently weld the seams for both ends of the pipes to be compatible with the inherent shape of the seams, as well as to automate welding. By pursuing a semi-automated process, the present invention relates to a welding system that can ensure convenient mass production and operation efficiency.

In general, the groundwater pumping device extends the core pipe bundle which extends a plurality of pipes such as a pumping pipe, a water level measuring pipe, and a plurality of cables such as a water level measuring wire and an underwater motor cable to a depth of the core. The bottom of the core pipe bundle is equipped with a submersible motor pump for the core and consists of a configuration for pumping the ground water by the operation of the upper and lower level switches mounted at a predetermined position.

According to the existing method, in order to install the installation members fixedly extended by several meters from the core, the pumping pipe and other members are integrally formed by using a rope or tape, but in this case, the binding force is not good and the construction efficiency is very high. In addition to the deterioration result, damages were caused by friction between means such as flanges or sockets installed at the connection part between the pumps and the external level of the water level measurement cable / submersible motor cable to extend the length of the pump. .

According to the prior art developed to solve this problem, as a flange structure for the development of wells, a part of the side of the flange is removed to form a space through which the cable and pipe can pass, or in advance according to the number and shape of the cable and pipe to be inserted. Techniques for incorporating various flange structures into pipes, such as forming through holes, have been attempted.

In addition, since the flange must be larger than the outer diameter of the pipe, almost all of them are temporarily connected to the end of the pipe, except that the pipe is manufactured by casting. The joint is welded to form a flange integrally with the end of the pipe.

Korean Automatic Patent No. 10-2015-0144513, “Automatic welding device for pipe butt welding and flange welding” not only enables pipe butt welding and flange welding, but also enables four-axis control to weld all the way down. According to the present invention, the cost reduction and the welding quality are improved.

According to the above technique, both pipes and flanges can be welded, but accordingly, a flange-specific welding process is provided, or, in particular, compared to a flange-specific welding device, such as a flange position correction and an automatic conveying process of the flange, the convenience is high. The problem with poor precision is pointed out.

On the other hand, in order to more firmly connect the pump, it may be more preferable to use a socket having a large area that can cover the connection area, in the case of the socket as described above it is very difficult and inefficient to cut the side portion, etc. There was a problem.

According to the related art developed to solve such a problem, a technique of grafting a structure of a functional socket for pipe development to a pipe has been attempted.

In the case of “pipe connecting socket”, Korean Patent No. 10-1557809, it is possible to fundamentally prevent the problem of the socket dropping out of the pipe and to connect it in a short time while preventing the leakage, and improve the coupling force between the pipe and the socket and to prevent the separation It relates to a pipe connecting socket having a coupling structure, which is formed by separating the first cover and the second cover opposite to each other, the grooves and protrusions are formed on the surface where the first and second covers abut each other, the adhesive is applied to each surface Although it is firmly adhesively bonded, it is difficult to guarantee that there is no possibility of leakage due to the fact that adhesion through grooves, protrusions and adhesives is hardly achieved, and it is possible to fix and support the installation member when used for an official well. There is no configuration at all, there is a problem that can not solve the above problems.

Therefore, it is more preferable to apply a welding technique for more firmly connecting the flange or the socket and the pipe. As described above, Korean Patent Publication No. 10-2014-0028466, "Pipe Pipe and Flange Welding Apparatus", is simple in construction. Although the technology of turning rollers is improved to improve welding quality at low cost, it does not pursue the automatic / semi-automatic process from the loading and discharging of pipes, but also controls the simple sensing of the turning rollers. Alternatively, unlike the socket, there is a problem in that it does not provide a separate welding function specialized in the peculiar structure of the pipe or the flange for the pipe.

As described above, the flange or socket applied to the pipe for pipe wells is more preferably provided with a functional space structure for accommodating the cable.

In addition, the conical protrusion 610 is inserted into and coupled to the pipe inserts 5a and 5a 'of the flange 2 or the socket 2' in the welding process in which the pipe 5 is rotated by the roller 330. It is possible to maintain the state to prevent the flange (2) or the socket (2 ') from being released from the pipe (5), in this way the coupling of the pipe (5) and the flange (2) or socket (2') during welding In the configuration to ensure the relationship, in the present invention, there is such a joint seam mounting device 600 and a well supporting device for a well to be described later.

Referring to FIG. 14, the welding robot 700 moves the welding arm 710 from the initial position to the welding area and rotates the pipe 5 according to the rotation of the roller 330 described above. 2 ') and the joining portion of the pipe 5 are welded over the circumference of the pipe 5.

The welding robot 700 includes a welding arm 710, a torch 720 mounted at an end of the welding arm 710, and a reel 730 for providing solder to the torch 720, and the welding robot 700. It is composed of a welding control unit for controlling the driving of the reel / welding arm / torch according to the detection of the sensor unit (S) mounted on one side, because it is similar to the function of the known welding robot 700, Detailed description of the function is omitted.

15 is a perspective view showing the structure of the flange support device for supporting the flange of the joints of the present invention, Figure 16 is a perspective view showing the structure of the socket support device for supporting the socket of the joints of the present invention to be.

When the welding is performed by the torch 720, the flange 2 or the pipe 5 rotates while the flange 2 or the socket 2 ', which is a fitting for the pipe, is mounted at the end of the pipe 5; The flange 2 or the socket 2 'may be oriented downward or biased due to the load of the socket 2', so that the flange 2 or the socket 2 'with the rotation of the pipe 5 More preferably, welding can be carried out with the flange 2 or the socket 2 'supported in a more stable manner by means of supporting the flange 2 or the socket 2' to prevent downward deflection when rotated. Do.

For this purpose, a seam support device is provided as a support means for supporting the flange 2 or the socket 2 ', which is a seam for the well, and such a seam support device supports the flange 2 so as to support the flange 2. And a socket support device 800'to support the device 800 and the socket 2 '.

First, referring to the flange support device 800 with reference to FIG. 15, the flange support device 800 is a flange transfer robot 520 mounts the flange (2) to the end of the pipe (5) and then the seam mounting device for a well ( Supporting the flange (2) from the time when the flange (2) is coupled to the end of the pipe (5) by the 600, the support groove 811 is based on the base consisting of the support piece 810, In addition to the correction unit 820, the pressure sensing sensor 870 mounted on one surface of the support piece 810 and the lifting control unit may be further included.

The support piece 810 is supported from the floor spaced apart from the front side in the welding area of the base 1 by two support tips 812 between the support grooves 811 and the left and right sides as described above. In this case, the support groove 811 may have a V groove structure or may have a structure similar to a U groove concave rounded to correspond to the outer circumferential surface shape of the flange 2.

That is, the support piece 810 supports the flange 2 in the shape of the flange 2 in order to prevent the flange 2 from lowering, or if the flange ( When 2) is downwardly in contact with the support piece 810 plays a basic role of allowing the flange 2 to rise back to its original position.

In this case, the buffer pad 830 made of an elastic material may be laminated on the surface of the support piece 810 to reduce the repulsive force due to contact with the flange 2.

Furthermore, the shock absorbing pad 830 is formed of a plurality of fine projections (not shown) in a state made of an elastic material to increase the surface area to properly absorb the impact generated when the contact with the flange.

In addition, the pressure sensor 870 may be additionally mounted on the surface of the support piece 810 (or the surface of the buffer pad).

The pressure sensor 870 measures the pressure by the flange 2 applied to the surface of the support piece 810 to generate a numerical pressure sensing signal.

The elevating correction unit 820 includes an elevating rod 821 that moves up and down while being connected to a lower surface of the support piece 810, and a rod driving means 822 that provides power for driving the elevating rod 821. Thereby slightly supporting or lowering the support piece 810.

That is, the lifting correction unit 820 may provide a base for raising / lowering the flange 2 to a fixed position, which is a welding position.

The elevating control unit includes a pressure determining unit and a differential driving control unit. The pressure determining unit receives the pressure sensing signal detected by the pressure detecting sensor 870 and compares the reference pressure information with the preset reference pressure information. The lifting correction unit 820 differentially raises or lowers the control according to the height of the numerical difference of the signals.

In other words, the flange is more precisely determined by controlling the upward and downward movement of the elevating rod 821 of the elevating correction unit 820 by determining the upward or downward inclination of the flange 2 according to the elevation of the pressure sensing signal. The characteristic which can correct | amend the mounting position of (2) can be provided.

At this time, the flange 2 of the present invention is because the two grooves of the fixing groove (7a) and the water level measuring tube holder (8a) can be formed inward from the outer peripheral surface in the pressure sensor 870 If the flange 2 is pulled downward when the error of the pressure sensing signal is detected or when these two grooves are not in contact with the support piece 810, it is impossible to properly support the pulley 2. It can be pointed out.

In order to prevent such a problem, first, the upper surface of the support piece 810 on the basis that the width of the fixing groove 7a of the fixing groove 7a of the flange 2 and the level pipe holder 8a is formed longer. The entire length (or the total length of the contactable surface based on the moment when the flange is in contact with the support piece) has the same length as the circumference of the flange 2, but the left side of the support piece 810 with respect to the support groove 811. Curvature radius smaller than the curvature radius of the outer surface (circumference) of the flange with a width smaller than or slightly smaller than the width of the water pipe holder 8a, which is shorter than the fixing groove 7a, on one side of the site ), The pressing projection 840 of the push switch structure (that is, the structure which compresses in a pressed state and then extends and restores to a normal state) protrudes upwardly as a reference to the support groove 811 of the support piece 810. Mounted on the left and right side protruding portion or the support piece 810 The side portion itself may be made of such a pressing protrusion 840.

In addition, it is possible that the pressure sensor 870 is mounted on each of the surfaces of the two pressing protrusions 840. According to the pressing protrusion 840, the outer surface of the flange 2 maintains its pressing state when it comes in contact with the pressing protrusion 840, and the fixing groove 7a, the level gauge tube holder 8a, and the pressing protrusion 840 respectively contact each other. As soon as it protrudes upward, the pressure change and period in this process are grasped to provide a basis for more precisely determining whether the pressing protrusion 840 coincides with the pressing pressure at a normal position in the pressing state. can do.

Furthermore, by chamfering the corner angles of both side portions of the pressing protrusion 840, the feeling of repulsion due to contact with the flange 2 can be minimized during pressing and restoring, and the pressing and restoring time and period are checked separately. By doing so, the rotational speed (welding speed) of the pipe 5 can also be provided with a basis for identifying and correcting.

In addition, the termination structure of the pressing protrusion 840 may include a first curvature portion 841 which protrudes downward into a first curvature and convex downward from a portion where the projection starts, and a first curvature at the end of the first curvature portion 841. Right and left symmetrical structure including a second curvature having a smaller curvature radius (which is a more rapid curvature) and a second curvature 842 protrudingly protruding upward, and a tip 843 that is an end of the second curvature 842. And the tip portion 843 may be equipped with a pressure sensor 870. At this time, the first curvature of the first curvature 841 is smaller than the radius of curvature of the outer circumference of the flange 2 to increase contact with the flange.

According to this structure, the pressing protrusion 840 is naturally inserted into the fixing groove 7a and the level gauge tube mounting portion 8a while contacting the outer surface of the flange 2 without any foreign matter or mounting distance caused by the rotation of the flange 2. The change in pressure value delivered to the pressure sensing sensor 870 can also provide a basis for more accurate measurements.

Also in a separate embodiment, the outer side of the grip bar 7b of the flange 2 protrudes outwardly or is further provided with a convex protrusion (not shown) on the outer side of the grip bar 7b. The convex outer surface of the convex protrusion to the grip bar 7b preferentially grasps the pressure transmitted by being in contact with the support piece 810, thereby providing a foundation for smoothly detecting pressure without error.

Flange position for the problem that the flange 2 is tilted downward or removed during the rotation and welding of the pipe 5 fitted to the pipe insertion portion 5a of the flange 2 by such a flange support device 800. As well as the correction, the curvature of the outer circumferential surface of the flange 2 provides a function to more effectively prevent the problem that the pressure sensing is not properly made when contact or non-contact with the support piece 810 is repeated.

Next, the socket support device 800 'will be described with reference to FIG. 16. As shown in FIG. 16, the socket 2' of the present invention has a protruding configuration due to the water level pipe holder 3 'and the cable fixing part 4'. Since the welding robot 700 incorrectly detects this and may cause a malfunction during welding, the position of the socket 2 ′ in which the welding robot 700 is coupled to the pipe 5, as well as the level measuring tube holder 3 ')' And the socket (2 ') are combined to match the position of the level pipe holder (3') and the cable fixing part (4 ') in order to accurately determine the initial position before the start of welding of the cable fixing part (4'). There is a need to partially rotate correct the pipe 5 by the roller 330.

The socket support device 800 ', which is a socket position correction means and a socket support means provided for this, is a socket transport robot 520' which mounts the socket 2 'at the end of the pipe 5, By firmly coupling the socket 2 'to the end of the pipe 5 by means of 600, it is primarily operated to correct the position of the socket 2' and secondarily supports the socket 2 'during the welding process. It means a configuration that works.

The socket support device 800 ′ may be installed at one side of the outer periphery of the base 1 to face the pipe position correcting device 400 described above.

Specifically, the socket support device 800 'includes a socket support 810' and a horizontal correction driver 820 '.

The socket support 810 'properly supports the three-dimensional outer circumferential surface projected by the water level tube holder 3' and the cable fixing part 4 'of the socket 2', and is used for welding without malfunction. In order to provide a function of providing the reference position of (2), it is composed of a plurality of bar types, and specifically includes an extension bar 812 ', a support bar 813', and a support piece 811 '. .

The extension bar 812 'is bent from the support plate 821' toward the base 1 and extends to reach the outer circumferential surface of the socket 2 'coupled to the pipe 5, and the support bar 813' The extension bar 812 'is bent in the direction of the socket and extends close to the socket 2', and the support piece 811 'is formed at the end of the support bar 813' to the outer circumferential surface of the socket 2 '. It is a configuration to be contacted.

Additionally, the support piece 811 'extends outwardly from the end of the support bar 813' with respect to the termination structure so as to appropriately correspond to the shape of the three-dimensional and curved outer circumferential surface of the socket 2 '. 811a 'and the horizontal extension portion 811b' extending horizontally outward from the concave bend extension portion 811a 'and the horizontal extension portion 811b' outward from the ends of the horizontal extension portion 811b '. It may be provided with an upward extension portion 811c 'extending rounded in the upper direction shorter than the extension length of.

In addition, the socket support part 810 'includes one of the above-described photo sensor and a proximity sensor, and includes a sensor part S for detecting whether the socket 2' is in contact, a proximity position, and the like.

The concave bend extension 811a 'is formed to be concave so as to correspond to the shape of the three-dimensional outer circumferential surface of the socket 2' to accommodate a three-dimensional structure such as the water level tube holder 3 'to the cable fixing part 4'. The horizontal extension 811b 'serves to substantially support or contact the outer circumferential surface of the socket 2', and the upward extension 811c 'serves as a socket (2). By extending in an upward direction corresponding to the curvature of the outer circumferential surface of '), it serves to increase the possibility of contact with the outer circumferential surface of the socket 2'.

The horizontal correction driving unit 820 'horizontally moves the support piece 811', and extends in the horizontal direction so as to be horizontally movable from the support plate 821 'and the support plate 821' which contact the support piece 811 '. A horizontal extension rod 822 'and a horizontal extension driver 823' for horizontal driving control of the horizontal extension rod 822 '.

In addition, the lifting correction driving unit 830 'lifts and moves the support piece 811'. The lifting correction driving unit 830 'is mounted on the lower surface of the horizontal correction driving unit 820' to lift and lower the horizontal correction driving unit 820 '. 811 'can be moved up and down.

The lifting correction driving unit 830 'is coupled to the lower surface of the horizontal correction driving unit 820' and the lifting correction rod 831 'for lifting and lowering, and the lifting correction function providing the lifting control function of the lifting correction rod 831'. It consists of a rod drive part 832 '.

Referring to the function and operation of the socket support device 800 'according to this configuration is as follows.

After the socket 2 'is more firmly coupled to the pipe 5 by the seam mounting device 600 for the well, the horizontal extension rod 822' of the horizontal correction drive unit 820 'is pulled out horizontally to support the support piece ( 811 ') contacts the outer circumferential surface of the socket 2'.

At this time, the support piece 811 'is to be brought into contact with the level measuring tube holder 3' and the cable fixing part 4 'in principle. When it is recognized through the detection of the sensor unit S (recognition of the shape of the water level measuring tube holder and the distance therefrom) that the 811 'is touched, the roller 330 after the horizontal extension rod 822' is horizontally retracted. ) Part of the socket 2 'to correct the position according to the rotation of the level measuring tube holder 3' to the cable fixing part 4 '.

When the support piece 811 'is brought into contact between the level measuring tube holder 3' and the cable fixing part 4 ', the roller 330 is partially rotated to end the level measuring tube holder 3'. Abuts against the support piece 811 '. In this process, the support piece 811 'acts as a barrier against the level measuring tube holder 3', so that the support piece 811 'and the level measuring tube holder 3' are in contact with each other. The part S may detect this and stop the rotation of the roller 330.

As a result, the correction can be performed to a position where the socket 2 'can be welded.

In addition, when rotating the pipe 5 to which the socket 2 'is coupled by rotating the roller 330 while performing welding, the three-dimensional shape of the level pipe holder 3' and the cable fixing part 4 'is fixed. Accordingly, by detecting the distance or contact with the support piece 811 'by the sensor unit S, the horizontal correction driving unit 820' and the elevation correction driving unit 830 'of the socket support device 800' are operated in real time. While continuously changing the position of the support piece 811 ', the support piece 811' can be appropriately positioned under the socket 2 '.

That is, due to the three-dimensional shape of the level pipe holder 3 'and the cable fixing part 4', the socket 2 'is rotated and caught by the support piece 811', or the outer peripheral surface of the socket 2 '. And the support piece 811 'is unnecessarily widened to provide a property that can prevent the problem of not properly supporting the socket 2' in real time.

At this time, according to the above-described shape and structure of the support piece 811 ', not only can the contact sensing of the sensor S be reinforced, but the support piece 811' is caught on the outer circumferential surface of the socket 2 '. It can also provide a property that can prevent at the same time.

In addition, a buffer pad (not shown) made of an elastic material may be stacked on the surface of the support piece 811 'to reduce the repulsive force due to contact with the socket 2'.

Furthermore, the shock absorbing pad is formed of an elastic material so that a plurality of fine protrusions are formed to increase the surface area so as to appropriately absorb the shock generated when contacting the socket 2 '.

In addition, it is possible to further mount the pressure sensor 870 'on the surface of the support piece 811' (or the surface of the buffer pad).

The pressure sensor 870 ′ measures the pressure by the socket 2 ′ applied to the surface of the support piece 811 ′ to generate a digitized pressure sensing signal. Furthermore, the pressure sensor 870 ′ is disposed at the boundary between the concave bend extension 811 a ′ and the horizontal extension 811 b ′ of the support piece 811 ′ and on one side of the upward extension 811 c ′. It is more desirable to be equipped with each so as to perform more detailed pressure sensing.

In this case, the horizontal correction driver 820 ′ and the lift correction rod driver 832 ′ may further include a pressure determiner and a differential drive controller, respectively, by the pressure sensor 870 ′ in the pressure determiner. By receiving the sensed pressure sensing signal and comparing it with the preset reference pressure information, the horizontal extension rod 822 'and the elevating correction rod 831' are respectively differentiated according to the height of the numerical difference between the reference pressure information and the pressure sensing signal. It performs the function of controlling up / down or left / right movement.

In other words, by determining the degree of upward or downward tilting of the socket 2 'according to the height of the pressure sensing signal as a numerical value, it is possible to control the movement width of each of the rods 822' and 831 'that move up and down horizontally. It is possible to provide a characteristic capable of correcting the mounting position of the socket (2 ').

As described so far, the configuration and operation of the automatic welding system of the flange or the socket and the pipe, which is a seam for pipe according to the present invention, have been expressed in the above description and the drawings, but this is merely an example and the idea of the present invention is described above. And not limited to the drawings, of course, various changes and modifications are possible within the scope without departing from the spirit of the present invention.
