Description

Technical Field

[0001] The invention relates to the technical field of pipeline processing, and in particular to an on-site processing device for a drainage pipeline. Background Art

[0002] During the processing, the pipeline will be cut and then welded to form the required pipeline. Plasma cutting is used in pipeline cutting. Compared with laser cutting, plasma cutting equipment has lower cost and maintenance cost.

[0003] Existing plasma cutting equipment is often installed on a robotic arm or on a rotating ring mounted on the surface of a round pipe. The former is suitable for large-scale factory processing, while the latter is more portable and suitable for large pipe fittings. The combination of a rotating ring and a plasma cutting head is achieved by fixing the rotating ring on the surface of the round pipe, rotating the rotating ring relative to the pipe, and causing the cutting head on the surface of the rotating ring to perform ring cutting on the pipe, such as a CNC machining device for spiral seam submerged arc welded steel pipes disclosed in Chinese patent CN202323207685.0. For thick pipes, the cutting edge needs to be subjected to secondary machining to form a groove, so that there is sufficient space when welding two pipes to ensure good fusion between the weld and the parent material.

[0004] The above patents and prior art have the following problems: In pipeline bevel cutting, the plasma cutting head will perform circular cutting along the pipe. As the cutting progresses, circular cutting waste will gradually be generated. As the waste ring gradually separates from the pipeline bevel, its weight distribution will change, causing the cutting gap to be gradually pulled and affected. As a result, the gradually increasing weight of the waste ring will pull the cutting gap to shrink, thereby affecting the discharge path of chips and slag, which can easily lead to deviations in the bevel angle or flatness of subsequent cutting. As the circular cutting progresses, slag will also be generated at the bottom of the cutting, resulting in low surface quality of the pipeline. Summary of the invention

[0015] As a preferred solution of the drainage pipeline on-site processing device of the present invention, wherein: The clamping unit also includes a clamping driving source, which is fixedly installed on the side of the base, and the output shaft of the clamping driving source moves through the base and is connected to the top frame; The opposite surfaces of the base and the top frame are fixedly connected with a bearing seat, and the surface of the bearing seat is equipped with a clamping contact that is in elastic contact with the pipe fitting.

[0016] Beneficial effects of the present invention: The plasma cutting member is started, so that the plasma gas ejected by the plasma cutting member is inclined to contact the pipe fitting, and then the rotary driving source is started, so that the rotary driving source drives the active member to rotate, and when the active member rotates, it drives the driven ring meshed at its bottom to rotate, and when the driven ring rotates, it drives the plasma cutting member installed on its surface to perform inclined ring cutting on the surface of the pipe fitting, so that an inclined welding groove is finally formed on the surface of the pipe fitting. When the driven ring drives the plasma cutting member to cut the groove on the surface of the pipe fitting, the stabilizing member is always pulled by the elastic member to contact and support the uncut position of the pipe fitting. Of course, in order to improve the anti-slip property of the support, a high-temperature resistant rubber layer can be wrapped at the front end of the stabilizing member to cooperate with the positioning plate. When the plasma cutting member does not cut the pipe fitting, the left and right sides of the processing unit are supported, thereby improving the stability of the plasma cutting member rotating with the driven ring; When the trigger arc segment does not contact the triggered member at that position, the triggered member is no longer driven, thereby releasing the tensile constraint of the elastic member, causing the elastic member to pull the limiting plate and the stabilizing member to reset, so that the stabilizing member passes through the slit of the preset corresponding relationship under the pulling of the elastic member, and its front end passes through the slit and enters the inside of the corresponding docking groove, so that the stabilizing member plays a supporting role in the slit, preventing the waste ring generated by the plasma cutting member from directly contacting the groove surface under the action of its own weight as the plasma cutting member cuts the groove of the pipe fitting, causing the subsequent slit to be pulled and changed, and then under the support of the stabilizing member, the waste ring is supported, thereby reducing the pulling of the waste ring on the slit, and the multiple stabilizing members arranged on the surface of the pipe fitting and arranged in a ring shrink when the plasma cutting member cuts, avoiding interference with the rotating ring cutting of the plasma cutting member, and the stabilizing member independently extends out for support after cutting, reducing the support waiting time, that is, reducing the time of the waste ring being pulled by its own weight, so that the waste ring generated by the cutting on the surface of the pipe fitting is supported by the multiple stabilizing members after being inserted into the slit, thereby further improving the relative stability of the weld.

[0017] When the plasma cutting piece is cutting, the reciprocating driving source is started, so that its output shaft drives the ring plate 1 to move forward and backward, and the forward and backward movement of the ring plate 1 drives the shovel ring block and the retaining ring plate to move forward and backward through the clamping ring groove 2. When the retaining ring plate moves forward and backward, its docking groove does not contact the stabilizing piece, so that the retaining ring plate moves forward and backward stably, so that when the shovel ring block moves forward and backward, it will intermittently scrape the connection between the opening and the inner wall of the pipe fitting, that is, the connection between the groove and the inner wall, so that the slag formed by the slag flowing down from this position is pushed and scraped away, thereby reducing the slag problem generated during the pipe cutting process, so that the generated slag is scraped and falls into the storage chamber for storage, and under the obstruction of the storage chamber, the slag cut by the plasma cutting piece will only fall on the surface of the storage chamber, and will not splash onto the inner wall of the pipe fitting, thereby reducing the difficulty of subsequent cleaning of the inner wall of the pipe fitting; The front end of the stabilizing member is located inside the docking groove after passing through the slit. When the stabilizing member rotates with the driven ring, the reciprocating driving source pulls back the baffle plate in advance, so that the baffle plate fits the side of the pipe. At this time, the limiting driving source releases the relative rotation restriction between the bottom ring plate and the shovel ring block, so that when the stabilizing member rotates with the driven ring, it will drive the baffle plate to rotate, so that the baffle plate relative to the grinding layer set on the pipe fitting performs rotational rough grinding on the side of the pipe fitting, thereby reducing residual adhesion scum after the side of the pipe fitting is cut. Therefore, the stabilizing member rotates to grind the groove surface in combination with the rotational grinding of the groove side, i.e., the side of the pipe fitting by the baffle plate linked to the stabilizing member, and then cooperates with the front and rear shoveling of the shovel ring block, thereby reducing the residual scum on the surface of the pipe fitting after cutting, and improving the surface quality of the pipe fitting after the groove is cut. After the cutting is completed, the stabilizing member supports the slit, and follows the grinding ring plate and the driven ring for follow-up grinding after the support, thereby performing grinding positioning on the basis of cutting support, reducing the secondary positioning process and improving the processing efficiency.

[0031] like Figure 12-15As shown, the output shaft of the reciprocating driving source 3086 and a plurality of telescopic rods 3087 are fixedly connected to the side of the bottom ring plate 3085 opposite to the baffle plate 308, and the side of the reciprocating driving source 3086 and the telescopic rods 3087 opposite to the bottom ring plate 3085 are fixedly connected to the surface of the fixing seat 303, and the surface of the fixing seat 303 installed on the inner wall of the pipe fitting 1 is the same as the structure installed on the fixing seat 303 on the outer surface of the pipe fitting 1, both of which are fixed driving source 3031 and positioning plate 3032 structures, and in order to ensure the effect of the fixed driving source 3031 pushing the positioning plate 3032 to support the processing unit 3, the positioning plate 3032 can be preferably an electromagnet, so that the positioning plate 3032 contacts the metal pipe, and the positioning plate 3032, which is preferably an electromagnet, obtains current and is adsorbed on the surface of the pipe fitting 1; The surface of the bottom ring plate 3085 is fixedly connected with a column 3091, and the bottom ring plate 3085 is fixedly connected to the limiting push source 2 309 through the column 3091. The output shaft of the limiting push source 2 309 passes through the bottom ring plate 3085 and is fixedly connected with a rubber head. The bottom of the open ring groove 30841 is provided with a limiting groove 30843 that is clamped with the rubber head. The limiting groove 30843 is preferably annular. The limiting push source 2 309 pushes the rubber head to be inserted into the interior of the limiting groove 30843 to achieve clamping. The reciprocating push source 3086 and the limiting push source 2 309 are preferably cylinders or electric telescopic cylinders controlled by PLC and encoder.

[0032] The surfaces of the shovel ring block 3084 and the bottom ring plate 3085 of the upper and lower parts and the baffle ring plate 308 are symmetrically fixed with the docking plate 3082, and the docking plates 3082 of the upper and lower parts are closed and fixed by bolts.

[0033] Operation process: Preparation before processing: The pipe 1 is placed between the base 201 and the top frame 202 by hoisting or lifting equipment, so that the clamping push source 204 controls the top frame 202 to move downward, so that the pipe 1 is clamped between the base 201 and the top frame 202, thereby avoiding accidental movement of the pipe 1 during the subsequent groove cutting process.

[0034] Then close the semi-ring part 1 301 and the semi-ring part 2 302 of the processing unit 3 to the surface of the pipe fitting 1, so that the upper and lower parts of the grinding ring plate 304 and the driven ring 305 and the ring plate 1 3034 are relatively closed through the docking plate 1 3041 fixed on their surfaces, and then fixed by bolts after closing, so that the grinding ring plate 304 and the driven ring 305 are fixed to the outer surface of the pipe fitting 1, and the shovel ring block 3084 and the bottom ring plate 3085 arranged on the upper and lower sides of the inner side of the pipe fitting 1 are closed through the docking plate 2 3082 on the surface, and then fixed with bolts, and the baffle ring plate 308 fixed on the side of the upper and lower shovel ring block 3084 is also closed through the docking plate 2 3082 on the surface, and then fixed by bolts, When the docking plate 1 3041 and the docking plate 2 3082 are closed, the grinding ring plate 304 and the driven ring 305 are manually or mechanically lifted to be coaxial with the pipe fitting 1, and the shovel ring block 3084 and the retaining ring plate 308 are coaxial with the pipe fitting 1, and the fixed driving source 3031 is started, so that the positioning plate 3032 is pushed by the fixed driving source 3031 and contacts the surface of the pipe fitting 1, so that the grinding ring plate 304 and the driven ring 305 are fixed to the outer surface of the pipe fitting 1, and the squeezing stabilizing member 3072 of the pipe fitting 1 is lifted. At this time, the elastic member 30722 is stretched, and the shovel ring block 3084 is fixed to the inner surface of the pipe fitting 1, so that the retaining ring plate 308 is fixed to the side of the pipe fitting 1, thereby completing the equipment assembly and fixation; Then, by loosening the nut on the surface of the pointer 30641 on the side of the plasma cutting member 3063, the angle of the rotating sleeve 3062 relative to the pipe 1 is adjusted, and the rotating shaft on the side of the rotating sleeve 3062 passes through the cutting bracket 3061 and the dial 3064, and drives the pointer 30641 on its surface to rotate, so that the angle of rotation of the pointer 30641 on the surface of the dial 3064 is the adjusted rotation angle of the rotating sleeve 3062, and after the plasma cutting member 3063 on the surface of the rotating sleeve 3062 is adjusted to the preset cutting groove angle relative to the pipe 1, the nut on the surface of the pointer 30641 on the side of the rotating sleeve 3062 is tightened to complete the fixation, thereby obtaining the rotation angle of the pointer 30641 relative to the dial 3064; Then, according to the rotation angle of the pointer 30641 on the side of the rotating sleeve 1 3062, the angle of the rotating sleeve 2 3071 relative to the pipe 1 is adjusted in sequence, so that the tilted extension line of the stabilizing member 3072 inside the rotating sleeve 2 3071 relative to the pipe 1 after adjustment is located in the middle of the groove cut of the pipe 1 by the plasma cutting member 3063, that is, after the adjustment of the rotating sleeve 1 3062 and the rotating sleeve 2 3071 is completed, the center line of the rotating sleeve 2 3071 is located on the extension line of the center line of the rotating sleeve 1 3062 after tilting, and the extension direction of the extension line is located on the high side of the tilt of the rotating sleeve 1 3062, so that when the rotating sleeve 1 3062 and the rotating sleeve 2 3071 are adjusted, the center line of the rotating sleeve 2 3071 is located on the extension line of the center line of the rotating sleeve 1 3062 after tilting, and the extension direction of the extension line is located on the high side of the tilt of the rotating sleeve 1 3062, so that when the rotating sleeve 1 3062 is ... When the second rotating sleeve 3071 moves to the front end, the central extension line of the shrunk stabilizing member 3072 is located at the center of the plasma cutting member 3063. During this process, the elastic member 3072 pulls the stabilizing member 3072 to contact the surface of the pipe 1. At this time, the elastic member 30722 is still in a stretched state, and the width of the stabilizing member 3072 is smaller than the width of the slit of the plasma cutting member 3063. Therefore, after the plasma cutting member 3063 and the stabilizing member 3072 are adjusted, the preparation before cutting the groove is completed, and then the positive electrode metal clamp is brought into contact with the surface of the pipe 1, so that the pipe 1 has a positive electrode, which is convenient for subsequent plasma cutting. Formal processing: The plasma cutting member 3063 is started, so that the plasma gas ejected by the plasma cutting member 3063 is inclined to contact the pipe 1, and then the rotary driving source 3036 is started, so that the rotary driving source 3036 drives the active member 3037 to rotate, and when the active member 3037 rotates, it drives the driven ring 305 engaged at the bottom to rotate, and when the driven ring 305 rotates, it drives the plasma cutting member 3063 installed on the surface thereof to perform inclined ring cutting on the surface of the pipe 1, so that an inclined welding groove is finally formed on the surface of the pipe 1; When the driven ring 305 drives the plasma cutting member 3063 to cut the groove on the surface of the pipe 1, the stabilizing member 3072 is always in contact with the uncut position of the pipe 1 under the pull of the elastic member 30722. Of course, in order to improve the anti-slip property of the support, a high-temperature resistant rubber layer can be wrapped at the front end of the stabilizing member 3072 to cooperate with the positioning plate 3032. When the plasma cutting member 3063 does not cut the pipe 1, the left and right sides of the processing unit 3 are supported, thereby improving the stability of the plasma cutting member 3063 rotating with the driven ring 305. Of course, the plasma cutting member 3063 can also be replaced with a laser cutting head or a flame cutting head, thereby improving the adaptability of the equipment. When the driven ring 305 drives the plasma cutting member 3063 to move, the trigger arc segment 3052 fixedly mounted on the surface of the trigger ring plate 3051 will first contact the triggered member 30761 distributed on the surface of the grinding ring plate 304 along the forward side of the rotation of the driven ring 305, so that the trigger arc segment 3052 drives the triggered member 30761 to rotate, and the rotation of the triggered member 30761 drives the winding drum 30762 to rotate, so that the winding drum 30762 rotates to retract the pulling member 3075, The pulling member 3075 pulls the stabilizing member 3072 away from the pipe 1 along the second rotating sleeve 3071 and the installation sleeve 30711. Finally, before the plasma cutting member 3063 approaches the stabilizing member 3072, the stabilizing member 3072 is pulled and lifted by the pulling member 3075, so that there is space between the stabilizing member 3072 and the pipe 1 for the plasma cutting member 3063 to move, so that when the plasma cutting member 3063 passes through, the plasma cutting member 3063 can cut the pipe 1 corresponding to the bottom of the stabilizing member 3072. After the cutting is completed, the part of the trigger arc segment 3052 and the plasma cutting member 3063 that is opposite to the forward side of the driven ring 305 will continue to drive the triggered member 30761 to rotate, so that the stabilizing member 3072 continues to rise for a while, and when the trigger arc segment 3052 is no longer in contact with the triggered member 30761 at this position, the triggered member 30761 is no longer driven, so that the stretching constraint of the elastic member 30722 is released, so that the elastic member 30722 pulls the limiting plate 30721 and the stabilizing member 3072 to reset, so that the stabilizing member 3072 passes through the slit of the preset corresponding relationship under the pull of the elastic member 30722, and its front end passes through the slit and enters the corresponding docking groove 3081, so that the stabilizing member 3072 plays a supporting role in the slit. To prevent the waste ring generated by the plasma cutting member 3063 from directly contacting the groove surface due to its own weight when cutting the groove of the pipe 1, causing the subsequent cut seam to be pulled and changed, the waste ring is supported by the stabilizing member 3072, thereby reducing the pulling of the waste ring on the cut seam. The multiple stabilizing members 3072 arranged on the surface of the pipe 1 and arranged in a ring shrink when the plasma cutting member 3063 cuts, so as to avoid interfering with the rotating ring cutting of the plasma cutting member 3063. After cutting, the stabilizing member 3072 extends out independently for support, which reduces the support waiting time, that is, reduces the time of the waste ring being pulled by its own weight, so that the waste ring generated by the cutting of the pipe 1 surface is supported by the multiple stabilizing members 3072 after being inserted into the cut seam, thereby further improving the relative stability of the weld.

[0035] While the plasma cutting member 3063 is cutting, the reciprocating driving source 3086 is started, so that its output shaft drives the ring plate 1 3034 to move forward and backward, and the forward and backward movement of the ring plate 1 3034 drives the shovel ring block 3084 and the retaining ring plate 308 to move forward and backward through the retaining ring groove 2 30842. When the retaining ring plate 308 moves forward and backward, its docking groove 3081 does not contact the stabilizing member 3072, so that the retaining ring plate 308 moves forward and backward stably, so that when the shovel ring block 3084 moves forward and backward, there will be an intermittent The connection between the opening and the inner wall of the pipe 1, i.e., the connection between the groove and the inner wall, is scraped to push and remove the slag formed by the slag flowing down from this position, thereby reducing the slag problem generated during the cutting process of the pipe 1, so that the generated slag is scraped and falls into the storage chamber 3083 for storage, and under the blocking of the storage chamber 3083, the slag cut by the plasma cutting element 3063 will only fall on the surface of the storage chamber 3083, and will not splash onto the inner wall of the pipe 1, thereby reducing the difficulty of subsequent cleaning of the inner wall of the pipe 1; When the plasma cutting member 3063 completes the ring cutting, the plasma cutting member 3063 returns to the original position and stops, so that the output shaft of the limiting driving source 1 3038 corresponds to the synchronous hole 3053, and the limiting driving source 2 309 is started to make its output shaft withdrawn from the inside of the limiting groove 30843, so that the shovel ring block 3084 can rotate relative to the bottom ring plate 3085, and then the limiting driving source 1 3038 is started to make the output shaft of the limiting driving source 1 3038 inserted into the inside of the synchronous hole 3053, so as to complete the connection between the grinding ring plate 304 and the driven ring 305, so that the grinding ring plate 304 can rotate with the driven ring 305, and then the rotation driving source 3036 drives the driven ring 305 to rotate through the active member 3037, so that The rotation of the driven ring 305 will be linked by the plug-in connection of the limiting driving source 3038, so that the driven ring 305 and the grinding ring plate 304 rotate synchronously, and the stabilizing member 3072 located on the surface of the groove cutting seam rotates with the grinding ring plate 304, so that the grinding layer on the surface of the stabilizing member 3072 rotates with the rotation of the grinding ring plate 304, so that the stabilizing member 3072 performs rough grinding on the groove, thereby reducing the accumulation of adhesion residual scum on the surface of the groove and improving the cleanliness of the groove surface. Of course, the front end of the output shaft of the limiting driving source 3038 can also be wrapped with a rubber layer to reduce the setting of the synchronization hole 3053, so that the output shaft of the limiting driving source 3038 extends out and directly presses against the surface of the driven ring 305, thereby reducing the rotation of the driven ring 305.

[0036] Of course, in order to prevent the grinding ring plate 304 from producing an unexpected rotational deviation when it rotates with the driven ring 305 when the grinding ring plate 304 does not rotate synchronously with the driven ring 305, an additional limiting push source 3038 can be fixedly installed on the surface of any fixed rod 3033, so that the output shaft of the limiting push source 3038 can be in contact with the side of the grinding ring plate 304 through the anti-slip rubber on its surface, thereby reducing the unexpected rotational deviation of the grinding ring plate 304 when the driven ring 305 rotates alone. When the grinding ring plate 304 is required to rotate with the driven ring 305, the output shaft of the limiting push source 3038 on the surface of the grinding ring plate 304 is inserted into the synchronization hole 3053, so that the driven ring 305 drives the grinding ring plate 304 to rotate. At this time, the front end of the output shaft of the limiting push source 3038 on the surface of the fixed rod 3033 does not contact the grinding ring plate 304, so that the grinding ring plate 304 rotates with the driven ring 305.

[0037] The front end of the stabilizing member 3072 is located inside the docking groove 3081 after passing through the slit. When the stabilizing member 3072 rotates with the driven ring 305, the reciprocating driving source 3086 pulls back the baffle plate 308 in advance, so that the baffle plate 308 fits the side of the pipe. At this time, the limiting driving source 309 releases the relative rotation restriction between the bottom ring plate 3085 and the shovel ring block 3084, so that when the stabilizing member 3072 rotates with the driven ring 305, the baffle plate 308 is driven to rotate, so that the baffle plate 308 is relative to the grinding layer set on the pipe fitting 1, and the side of the pipe fitting 1 is rotated and roughly polished, thereby reducing the residual on the side of the pipe fitting 1 after cutting. Adhering scum, therefore, the stabilizing member 3072 performs rotational grinding on the groove surface and the stabilizing member 3072-linked baffle plate 308 performs rotational grinding on the groove side, i.e., the side of the pipe 1, and then cooperates with the front and rear shoveling of the shovel ring block 3084, thereby reducing the residual scum on the surface of the pipe 1 after cutting, and improving the surface quality of the pipe 1 after the groove is cut. After the cutting is completed, the stabilizing member 3072 supports the cut seam, and after the support, the follow-up grinding ring plate 304 and the driven ring 305 are performed with the follow-up grinding, so that grinding positioning is performed on the basis of cutting support, reducing the secondary positioning process and improving the processing efficiency.
