Description

A standardized device for pipeline prefabrication operation

Technical Field

The invention relates to the field of pipe prefabrication processing, in particular to a standardization device for pipe prefabrication operation.

Background

In the process of prefabricating and processing industrial pipelines, particularly pipelines in the petroleum and petrochemical pipeline industry, the variety of pipe fittings is various, such as flanges, elbows, reducer heads, tee joints and the like. These pipes are different in shape, and for example, circular, curved, conical, and T-shaped; the pipes are also different in diameter, for example DN50, 80, 100, 150, 200, 250, 300, etc., and the pipe wall thickness is also varied, for example SCH20, SCH30, SCH40, SCH60, SCH80, SCH100, etc. The difference of the shapes and the sizes of the pipe fittings leads to the fact that the ratio of manual operation is extremely large and the degree of mechanization, automation and intellectualization is very low in the operation processes of hoisting, transporting, polishing, storing, assembling, welding and the like of the pipe fittings.

With the improvement of labor cost, the number of skilled workers is reduced, and the automation and intellectualization requirements of pipeline prefabrication are stronger and stronger.

In the prior art, in order to improve the working efficiency and ensure the working quality as much as possible, various tools are adopted to adapt to one or two pipe fittings. However, none of the tools can be applied to all pipes, and even if the tools are applied to a certain pipe, the tools are only used for manual operation (such as manual pairing) or semi-automatic operation (such as semi-automatic welding) of a subsequent process, and cannot be applied to the requirements of automatic and intelligent operation of the subsequent process.

In order to adapt to the automatic and intelligent pipeline prefabricating operation such as hoisting, transporting, polishing, storing, assembling, welding and the like, the method adopted in the prior art is as follows: the machine for automatically and intelligently completing the working procedures of hoisting, transporting, polishing, storing, assembling, welding and the like is designed to be directly suitable for various pipe fittings. However, this technical approach has proven to be infeasible. So far, no machine which can completely realize automatic and intelligent operation and can be directly applied to various pipe fittings exists in the market. Even if such a machine can be designed, the structure thereof is extremely complicated, and there are disadvantages that the manufacturing cost is high, the application range is limited, and the like.

Therefore, those skilled in the art have endeavored to develop a standardized apparatus for pipe prefabrication, which is constructed by previously installing various pipe elements into the standardized apparatus to form one or more unified pipe element modules, and then designing automated and intelligent machines for hoisting, transporting, polishing, storing, assembling, welding, etc. to be applicable only to the unified pipe element modules, thereby simplifying the structure of the machines and reducing the manufacturing cost of the machines.

Detailed Description

The embodiments of the present invention are described below with reference to specific embodiments, and other advantages and effects of the present invention will be easily understood by those skilled in the art from the disclosure of the present specification. The invention is capable of other and different embodiments and of being practiced or of being carried out in various ways, and its several details are capable of modification in various respects, all without departing from the spirit and scope of the present invention. It is to be noted that the features in the following embodiments and examples may be combined with each other without conflict.

It should be noted that the drawings provided in the following embodiments are only for illustrating the basic idea of the present invention, and the drawings only show the components related to the present invention rather than the number, shape and size of the components in actual implementation, and the type, quantity and proportion of the components in actual implementation may be changed freely, and the layout of the components may be more complicated.

Some exemplary embodiments of the invention have been described for illustrative purposes, and it is to be understood that the invention may be practiced otherwise than as specifically described.

The invention provides a standardized device 100 for prefabricating a pipeline, which is used for installing a pipe fitting 200 to be processed, wherein the pipe fitting 200 to be processed comprises but is not limited to a flange, an elbow, a reducer and a tee joint. When in use, the pipe fitting 200 to be processed is installed in the standardized device 100 to form a pipe fitting module with uniform specification, and then the pipe fitting module is subjected to corresponding prefabrication processing procedures by utilizing an automatic and intelligent machine for hoisting, transporting, grinding, storing, assembling, welding and other procedures, so that the machine only needs to be considered and suitable for the uniform pipe fitting module during design, and various pipe fittings with different shapes, sizes and wall thicknesses do not need to be considered, therefore, the machine is easier to realize automation and intelligence, the structure of the machine can be simplified, and the manufacturing cost of the machine can be reduced.

As shown in fig. 1, 3, 7 and 8, the standardized apparatus 100 for pipe work according to the present invention includes a frame 10, a pipe fixing part and a pipe positioning part. The faces of the frame 10 enclose a receiving space 101 for receiving a pipe 200 to be processed. The pipe fixing member is disposed in the accommodating space 101 and detachably coupled to the frame 10 by an L-shaped positioning part. The pipe fixing member is used to fix the pipe 200 to be processed in the accommodating space 101. The pipe positioning component is detachably connected with the pipe fixing component or the frame 10, and can be positioned in a proper position in or on the frame 10 according to the size of the pipe 200 to be processed, so as to adjust the position of the pipe 200 to be processed, such as adjusting the height of the pipe 200 to be processed or the relative position of the pipe 200 to be processed and the frame 10, so that when different pipe 200 to be processed are loaded into different standardizing devices 100, the pipe 200 to be processed has a relatively uniform or matched posture, and the subsequent processes of grinding, assembling, welding and the like can be favorably carried out without considering the positioning of the pipe 200 to be processed in the processes as long as the standardizing device 100 is in a preset posture.

As shown in fig. 9 and 10, the frame 10 has six faces forming a square or rectangular parallelepiped.

The frame 10 has a first face 102 for pipe access. In some embodiments, as shown in fig. 5 and 6, the first face 102 is entirely hollow, i.e., is open throughout, facilitating installation of the tubular member 200 to be processed. In some embodiments, the pipe loading device can be used to fix the pipe to be processed in a standard posture, then the first surface 102 of the frame 10 is aligned with the pipe 200 to be processed, and the frame 10 is moved to be sleeved outside the pipe 200 to be processed, so that the pipe 200 to be processed is located in a proper position in the frame 10. The pipe to be processed 200 is then fixed at a preset position using the pipe fixing part and the pipe positioning part. In some embodiments, at least a portion of the first face 102 may be hollow, i.e., an opening may be provided in the first face 102, the opening having an area smaller than the area of the first face 102, through which the pipe 200 to be processed enters and exits the standardized device 100.

The frame 10 has a second surface 103 as a vertical positioning and conveyance reference surface. The second face 103 may be disposed to perpendicularly intersect the first face 102. When the standardisation device 100 containing the tubular element 200 to be worked is in transit, the second face 103 is in contact with the machine for transit, acting as a reference face for transit. Meanwhile, in order to facilitate the pipe fitting 200 to be processed to have a uniform center height and facilitate subsequent processes such as polishing, assembling, welding and the like, the second surface 103 serves as a reference surface for positioning up and down, so that different pipe fitting modules have a uniform reference, namely, a uniform height. The second surface 103 may be partially hollow or may be solid.

The frame 10 has a third face 104 perpendicular to the first face 102. As shown in fig. 5 and 6, the third face 104 is hollow as a whole, i.e. the third face 104 is open, so that the third face 104 and the first face 102 together form a passage for the pipe 200 to be processed to enter and exit the standardized device 100, further facilitating the pipe 200 to be processed to enter and exit the standardized device 100. The third surface 104 may also be partially hollow to serve as a supporting member for improving the rigidity of the entire frame 10, and at the same time, the third surface is hollow to reduce the weight. When the third face 104 is provided as an entirely hollow space, at least two detachable crosspieces may be provided on the third face 104, as shown in fig. 1. One of the crosspiece rods (i.e., the first crosspiece rod 108) is arranged at the joint of the first surface 102 and the third surface 104, and before the pipe fitting 200 to be processed is clamped, the first crosspiece rod 108 can be detached if necessary, so that the pipe fitting 200 to be processed can enter conveniently; after the pipe 200 to be processed is entered, the first crosspiece 108 is connected to ensure the rigidity of the frame 10. At least one of the crosspieces (i.e., the second crosspiece 109) is used to position the tube fixing member, ensuring the strength of the tube fixing member, i.e., after the tube fixing member is installed in a proper position in the frame 10 according to the size of the tube 200 to be processed, the second crosspiece 109 can be fixed near and next to the tube fixing member, thereby ensuring the strength of the tube fixing member and improving the rigidity of the frame. It should be understood that the number of the second crosspiece 109 may be set to one or more according to actual requirements.

For the frame 10, the fourth surface 105, the fifth surface 106 and the sixth surface 107 are used for supporting and improving the rigidity of the whole frame 10. In addition, a plurality of through holes are formed in part or all of the fourth surface 105, the fifth surface 106 and the sixth surface 107 of the frame 10, as shown in fig. 1, the through holes may include a lifting hole 110, and may further include a positioning hole 111 and a mounting hole 112, wherein the lifting hole 110 facilitates the lifting operation of the standardized apparatus 100 by the truss manipulator, and the weight of the frame 10 can be reduced by forming the lifting hole 110; the positioning hole 111 is used for positioning in the processes of assembly, welding and the like, and can be a tapered hole; the mounting holes 112 may be used to mount the rail or the circular plate 72 of the hold-down mechanism, for example, by providing a plurality of mounting holes 112 at different locations on the frame 10 adjacent the third face 104, and then, after the rail is set in place, bolts are screwed into the rail through these mounting holes 112 to secure the rail. The through holes enable each standardization device 100 to have hoisting holes 110 and positioning holes 111 with uniform specifications and positions, and automation and intellectualization are facilitated. In some embodiments, the parts of the fourth, fifth and

sixth faces

105, 106 and 107 other than the through hole 110 are provided to be solid. In some embodiments, the fourth surface 105, the fifth surface 106, and the sixth surface 107 are hollowed out, which can reduce the weight of the frame 10 and save the material for manufacturing the frame. It should be understood that the fourth surface 105, the fifth surface 106, and the sixth surface 107 may be hollow-out portions of the three surfaces, and solid-core portions; the three surfaces can be all hollowed or solid; the specific setting mode can be selected according to actual requirements.

The sixth surface 107 of the frame 10 can also be used as a front and rear positioning surface to realize accurate matching with machines in the processes of transportation, grinding, storage, assembly, welding and the like.

The pipe fixing member is detachably coupled to the frame 10 and can be positioned at a proper position within the frame 10 according to the size of the pipe 200 to be processed.

The pipe fixing part and the pipe positioning part are combined together to realize the positioning and fixing of the pipe 200 to be processed. The pipe fixing component and the pipe positioning component can be arranged at proper positions in the frame 10 according to the size of the pipe 200 to be processed, so that the standardization device 100 is suitable for the pipe 200 to be processed with different sizes and shapes on the one hand, and the automation and intelligent processing of different pipe 200 to be processed on the other hand are facilitated. For example, when a series of pipes with the same specification are processed, the shapes of the tee joint and the elbow are different, when a traditional machine is used for hoisting, transporting, polishing, storing, assembling, welding and other operations, if automation and intellectualization are to be realized, the designed machine can be suitable for both the tee joint and the elbow, the complexity of the machine per se is undoubtedly increased, and the manufacturing cost of the machine is increased. The standardized device 100 of the present invention can be adopted as the standardized device 100 of the same specification, and since the frame 10 is of the same specification, different pipes 200 to be processed are installed in a plurality of pipe modules formed in each standardized device 100, and have uniform hoisting holes 110 and positioning holes 111, and the pipe 200 to be processed in each pipe module has a uniform central height (relative to the second surface 103 of the frame 10, i.e. the reference surface) at the end part extending out of the frame 10 and a relatively fixed length through the pipe fixing part and the pipe positioning part, therefore, when designing an automatic and intelligent machine for the processes of hoisting, transporting, polishing, storing, pairing, welding, etc., only the specification of the standardized device 100 needs to be considered, and the standardized device can be suitable for different pipes 200 to be processed, which is very beneficial to realizing automation and intelligence, the machine structure is simplified, and the machine manufacturing cost is reduced.

In some embodiments, as shown in fig. 1, the pipe fixing component is a fixing baffle 20, and the fixing baffle 20 is connected to the frame 10 through an L-shaped positioning part 21, specifically, the L-shaped positioning part 21 includes a first portion and a second portion, the first portion is connected to a surface of the frame 10, and the second portion is connected to the fixing baffle 20. When the fixed barrier 20 is configured to be coupled to the third surface 104 of the frame 10, if the third surface 104 is hollow, the fixed barrier 20 is coupled to the crossbar on the third surface 104 by the L-shaped positioning member 21. After the installation position of the pipe fitting in the standardizing device 100 is determined according to the type and size of the pipe fitting, the fixing baffle 20 is installed at the position through the L-shaped positioning part 21, and then the pipe fitting 200 to be processed is fixed on the fixing baffle 20 through the pipe fitting positioning part.

In some embodiments, as shown in fig. 1 and 3, the number of the fixed baffles 20 is two, two fixed baffles 20 are oppositely disposed and parallel to each other, and the two fixed baffles 20 are respectively perpendicular to the first face 102 of the frame 10. The pipe fitting positioning component is a first positioning clamping plate 30 respectively arranged on the two fixed baffle plates 20, and the two first positioning clamping plates 30 are connected with the fixed baffle plates 20 through guide columns. Specifically, a plurality of holes for passing through the guide posts are formed in the fixing baffle 20, the guide posts are connected with the first positioning clamp plate 30 after passing through the holes, two rows of fastening screws are arranged on the fixing baffle 20, and the distance between the first positioning clamp plate 30 and the fixing baffle 20 can be adjusted by rotating the fastening screws. This structure is suitable for the pipe fitting 200 to be processed of the elbow, tee, or the like type. In use, the two first positioning clamping plates 30 are screwed on the pipe fitting 200 to be processed through the set screws, so that the two first positioning clamping plates 30 clamp the pipe fitting 200 to be processed. In some embodiments, the pipe positioning component may further include other positioning parts, as shown in fig. 2 and 4, such as a positioning V-plate 50 and a positioning bolt 60, to support the pipe 200 to be processed and to press the pipe 200 to be processed. The positioning V-plate 50 may be provided on the second face 103 of the frame 10, and the positioning screw 60 may be provided on the crosspiece bars 108 and 109 of the third face 104. The positioning V-shaped plate 50 and the positioning screw 60 can be arranged on other surfaces as well, and are selected according to actual requirements. In this embodiment, due to the influence of the self-weight of the pipe 200 to be processed, the friction force between the first positioning clamp plate 30 and the pipe 200 to be processed is not enough, and the pipe 200 to be processed may be displaced downward by gravity, and at this time, it may be supported and clamped by the positioning V-shaped plate 50 and the positioning screw 60. Under the action of the positioning clamping plate 30, the positioning V-shaped plate 50 and the positioning bolt 60, the pipe fitting 200 to be processed can be subjected to posture shaping, and it is ensured that the end of the pipe fitting 200 to be processed, which extends out of the standardizing device 100, has a uniform height relative to a reference plane, and the extending length is relatively fixed. In some embodiments, the first positioning clamp plate 30 may be covered with a layer of polyurethane, after the first positioning clamp plate 30 clamps the pipe fitting 200 to be processed, due to the elasticity of the polyurethane, the polyurethane contacting with the pipe fitting 200 to be processed is deformed, the deformation matches with the shape of the pipe fitting 200 to be processed, especially for pipe fittings such as a tee joint and an elbow, the shape is an arc surface, and the deformation of the polyurethane matches with the arc surface, so that the first positioning clamp plate 30 forms a deformation similar to an arc shape, and wraps the tee joint and the elbow. When the tee and the elbow are not heavy, the tee and the elbow can be supported by the first positioning clamp plate 30 without positioning the V-shaped plate 50 and the positioning screw 60. It should be noted that the elbow and the tee have different contour, as shown in fig. 1, the surface of the tee contacting with the first positioning clamp plate 30 is the outer surface of a section of pipeline in a straight line shape, in this case, the first positioning clamp plate 30 can be set as a straight line plate, and the tee can be well positioned and clamped by clamping on the outer surface of the section of pipeline in a straight line shape; as shown in fig. 3, the elbow is curved in an arc shape, so that when the elbow is positioned, the first positioning clamp plate 30 can be set to be an arc plate matched with the elbow, so that the contact area between the first positioning clamp plate 30 and the elbow is large, and the elbow can be better clamped. In some embodiments, to accommodate different sized elbows for the same retainer plate 20 while reducing hole interference, multiple sets of guide post holes and bolt holes are provided at different locations on the retainer plate 20 for connection and nailing with the first retainer plate 30.

In some embodiments, as shown in fig. 7 and 8, the number of the fixed baffles 20 is one, and the fixed baffles 20 are parallel to the first face 102 of the frame 10. The pipe positioning member is a positioning chuck 40 provided on the fixing stop 20. This structure is suitable for the pipe 200 to be processed of flange, large and small head type. In use, the installation position of the pipe 200 to be processed in the standardizing device 100 is determined according to the type and size of the pipe 200 to be processed, and then the fixing baffle 20 is fixed at the position, and then the pipe 200 to be processed is fixed in the positioning chuck 40. The positioning chuck 40 may be a three-jaw chuck. By properly positioning the positioning chuck 40, it is ensured that the relative positions of the different pipes 200 to be processed with respect to the frame 10 are uniform or matched when installed in the standardized apparatus 100, for example, the heights of the different pipes 200 to be processed with respect to the reference plane are uniform. The arrangement is convenient for realizing automation and intellectualization of working procedures such as polishing, assembly, welding and the like. In some embodiments, the pipe positioning component may further include a positioning V-plate 50 and a positioning screw 60 to support the pipe 200 to be processed and to press the pipe 200 to be processed. The positioning V-plate 50 may be provided on the second face 103 (i.e., the reference face) of the frame 10, and the positioning screw 60 may be provided on the third face 104. The LED lamp can also be arranged on other surfaces and selected according to actual requirements.

In some embodiments, as shown in fig. 5 and 6, the tube securing component may be two opposing tightening mechanisms 70 disposed within the frame 10. The tightening mechanism 70 includes an internally threaded annular plate 71 and an externally threaded circular plate 72, the annular plate 71 being threaded onto the outer circumference of the circular plate 72 such that the annular plate 71 can rotate about the circular plate 72, the annular plate 71 being movable in the axial direction of the circular plate 72 by the action of the threads. A lever 73 is provided on the outer circumference of the annular plate 71, and by pulling the lever 73, the annular plate 71 can be easily rotated. The circular plate 72 is fixed to the frame 10 by bolts, for example, a plurality of circular holes 113 are formed in the fourth surface 105 of the frame 10, and the circular plate 72 is fixed by screwing the bolts into the circular plate 72 through the circular holes 113. The number of circular holes 113 can be set according to actual requirements, and is set to six here, and six circular holes 113 are arranged to be 3 rows, two in each row. Pipe fitting locating component includes two second location splint 74 that set up relatively, and two second location splint 74 contact with two tight mechanisms 70 in top respectively, and when pulling annular plate 71 and rotate, annular plate 71 is along the axial of circular plate 72 and inwards moves, and it is tight toward waiting to process pipe fitting 200 direction top with two second location splint 74 respectively, and at this moment, annular plate 71 rotates the back, produces the tight power in top, transmits power for second location splint 74 to will wait to process the pipe fitting location on predetermineeing the posture. The area of second location splint 74 can be approximately equal to the area of the fourth face 105 of frame 10, and sets up polyurethane on the second location splint 74, and under the effect of top tension, polyurethane takes place to warp for there is great area of contact between the both sides of waiting to process pipe fitting 200 and the second location splint 74, thereby two second location splints 74 can live the both sides parcel of waiting to process pipe fitting 200, provide great frictional force and holding power. At this time, even if the positioning V-shaped plate and the positioning screw are not provided, the pipe to be processed can be supported well only by the two second positioning clamps 74. The four corners of the second positioning clamp plate 74 may be provided in an L shape, so that the second positioning clamp plate 74 is engaged with the crosspiece of the frame 10 through the corners of the L shape, and the second positioning clamp plate 74 itself has a certain thickness, so that there is no need to provide a coupling member between the second positioning clamp plate 74 and the tightening mechanism 70, and the second positioning clamp plate 74 is directly placed in the frame 10, and the second positioning clamp plate 74 is not inclined. In some embodiments, as shown in fig. 5, a force transfer square plate 75 and a force transfer block 76 may also be provided between the second retaining strap 74 and the tightening mechanism 70. In order to enable the construction to accommodate a larger range of sizes of pipe, due to the limited distance the annular plate 71 travels along the circular plate 72, a force transfer square plate 75 and a force transfer block 76 are provided. For example, as shown in fig. 5, when the pipe size is small, even if the annular plate 71 is moved to the maximum distance, the second positioning jaw 74 cannot be made to clamp the pipe, and at this time, the force transmission square plate 75 and the force transmission block 76 are provided between the second positioning jaw 74 and the tightening mechanism 70, and the distance between the second positioning jaw 74 and the tightening mechanism 70 is increased, so that the second positioning jaw 74 can clamp the pipe well. The force transmission square plate 75 is in contact with the annular plate 71, and the force transmission square plate 75 is square, so that when the annular plate 71 rotates, the force transmission square plate 75 cannot rotate along with the annular plate 71, and the stability of the device is guaranteed. The force transfer block 76 is located between the force transfer square plate 75 and the second clamp plate 74, and may be formed of an aluminum alloy having a low specific gravity, and a plurality of parallel force transfer blocks 76 may be provided according to the size of the pipe. As shown in fig. 6, when the pipe is large in size, the force-transmitting square plate 75 and the force-transmitting square 76 may not be used, but the tightening mechanism 70 may directly apply the tightening force to the second clamp 74.

Adopt tight structure 76 in top, can be applicable to pipe fittings such as elbow and tee bend, at this moment, because the area of second location splint 74 is very big, need not to consider the elbow and the tee bend shape and set up the location splint of different shapes, only need use the second location splint 74 as shown in the figure, need not to change the location splint and just can be applicable to the elbow and the tee bend of different sizes and shapes, the commonality is better.

The frame 10 of the standardizing apparatus 100 according to the present invention may be manufactured by cutting and welding a steel plate and/or a square pipe, or may be manufactured by casting and machining the entire frame. Then, the six faces of the frame 10, the inner side joints of the frame 10, the through holes 110, and the like are machined accordingly to ensure positioning accuracy. The manufacturing process of the frame 10 is simple, and mass production can be realized, thereby effectively reducing the manufacturing cost of the entire standardized apparatus 100.

The use of the standardisation means 100 according to the invention is as follows:

the pipe fitting 200 to be processed is shaped in a standard posture by using a pipe fitting loader, then the standardized device 100 is sleeved outside the pipe fitting 200 to be processed, and the pipe fitting 200 to be processed is fixed in the standardized device 100 through the combination of a pipe fitting fixing part and a pipe fitting positioning part and/or a combined positioning part. At this time, the pipe modules formed by different pipes 200 to be processed have uniform or matched relative positions of the pipes to be processed and the frame, for example, the pipes 200 to be processed have uniform center heights and relatively fixed lengths extending from the frame 10.

The lifting holes 110 on the standardized device 100 are utilized to lift the pipe fitting, and different pipe fitting modules are provided with the same lifting holes 110, so that the truss manipulator is designed to be only suitable for the lifting holes of the standardized device 100 without considering different shapes and sizes of the pipe fittings.

The use of reference surfaces (e.g., second surface 103 and sixth surface 107) on the standardized apparatus 100, which have a uniform, regular shape and flatness, facilitates the transport of the individual pipe modules by the transport system and their placement in a stereoscopic warehouse for storage. These conveyors and warehouses also need to be designed with only the specifications of the standardized apparatus 100 taken into account, and not with the shape and size of the particular pipe.

By means of the unified overall dimension of the standardization device 100 and the positioning holes formed in the standardization device 100, the pipe fitting can be accurately positioned, reliably clamped and rotated around the center in the processes of polishing, assembling, welding and the like, and intelligent polishing, intelligent assembling and intelligent welding of the pipe fitting and the pipe are facilitated.
