Technical Field

[0001] The present invention relates to the technical field of two-phase flow meters, and particularly to a welding device for a two-phase flow meter. Background Art

[0002] A two-phase flow meter is an instrument used to measure the flow rates of each phase and the total flow rate of a mixture of two different fluids (such as gas-liquid, liquid-solid, etc.), and is widely used in the fields of oil and gas, chemical industry, and nuclear energy. Among them, before the flow meter is put into use, it is necessary to weld the main body with fixed fittings such as flange plates, so a welding device is required.

[0003] Compared with the existing welding devices, the following defects still exist: Conventional welding devices use spot welding. After contacting according to the welding position, welding is carried out point by point. This method will cause the welding area to be rough and uneven, which not only affects the appearance but also causes phenomena such as rusting of the welding points, reducing the welding efficiency. At the same time, after the two-phase flow meter is welded, due to the high temperature at the welding area, it is necessary to cool it down. At this time, conventional equipment mostly uses natural air cooling for cooling, resulting in a reduction in the cooling efficiency. Summary of the Invention

[0021] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without making creative efforts belong to the scope of protection of the present invention.

[0022] Please refer to Figure 1-8 As shown, the present invention is a welding device for a two-phase flowmeter.

[0023] Embodiment 1 Please refer to Figures 1-3 , Figure 5 and Figure 6 In, the present invention provides a technical solution: a positioning cross plate 4 is arranged inside the fixed installation table board 1, a limit clamping block 407 for positioning and clamping the two-phase flowmeter is arranged inside the positioning cross plate 4, and a rubber buffer pad 408 is arranged inside the upper end of the limit clamping block 407; Furthermore, the gear vertical plate 401 and the adjusting roller shaft 4011 are connected in a meshing manner, and the gear vertical plate 401 and the positioning cross plate 4 are vertically and fixedly connected, so that the positioning cross plate 4 can move up and down reciprocally. After the first servo motor 4012 is turned on, the gear vertical plate 401 meshingly connected with the adjusting roller shaft 4011 can be driven to move up and down.

[0024] Furthermore, convex structures are provided at both ends of the positioning transverse plate 4, and the positioning transverse plate 4 forms a snap-fitting sliding structure in the first limiting groove 2 and the second limiting groove 303 through the convex structures in turn, so that the positioning transverse plate 4 can be stably raised and lowered through the first limiting groove 2 and the second limiting groove 303 to avoid shaking or displacement.

[0025] Furthermore, the first conical disk 404 and the second conical disk 405 are connected in an meshing manner, and the reciprocating screw rod 406 vertically fixedly connected to the outer end of the second conical disk 405 is connected to the limiting clamp block 407 in a threaded manner, so that when the second servo motor 403 is turned on to rotate the first conical disk 404, the second conical disk 405 meshingly connected to the first conical disk 404 can be driven to rotate synchronously, and the diameter of the first conical disk 404 is larger than the diameter of the second conical disk 405, so that the first conical disk 404 can drive the four second conical disks 405 to rotate synchronously.

[0026] Furthermore, an extension plate is provided in the middle of the limit clamp 407 and is located above the inner side of the positioning cross plate 4, which is used to shield impurities generated during welding. The limit clamp 407 and the rubber buffer pad 408 are connected by bonding. The inner sides of the limit clamp 407 and the rubber buffer pad 408 are both arc-shaped, which can increase the clamping effect of the two-phase flow meter components under the action of the rubber buffer pad 408.

[0027] Specifically, firstly, the fixed installation plate 1 is placed at the designated position, and then the two-phase flow meter components to be welded are butted up and down, and then placed at the center of the upper surface of the positioning horizontal plate 4, and the first conical disk 404 and the second conical disk 405 are connected in a meshing manner, and the second conical disk 405 is divided into four equal parts about the center point of the first conical disk 404. When the second servo motor 403 is turned on to rotate the first conical disk 404, the first conical disk 404 can drive the meshing second conical disk 405 to rotate synchronously. The first conical disc 404 is symmetrically arranged with respect to the center line, but the meshing rotation is opposite, which drives the reciprocating screw 406 fixedly connected to the outer end of the second conical disc 405 to rotate in the opposite direction, so that the limit clamp 407 threadedly connected to the reciprocating screw 406 moves in the positioning cross plate 4 through the clearance groove 402. Similarly, when the limit clamp 407 moves inward, the other three parts divided into four parts are driven to move inward at the same time, so that the rubber buffer pad 408 bonded to the inner end of the limit clamp 407 can be used to position and clamp the bottom of the parts of the two-phase flow meter. It is also provided that the middle part of the limit clamp 407 is extended toward both ends. When the limit clamp 407 is displaced, the extended part is located at the inner upper side of the positioning horizontal plate 4 and moves in close contact, so as to block and block the clearance groove 402, and prevent impurities generated during welding from entering the positioning horizontal plate 4 and causing damage to the first conical disk 404, the second conical disk 405 and the reciprocating screw 406. The gear vertical plate 401 is connected with the adjusting roller shaft 4011 in a meshing manner, and the gear vertical plate 401 is symmetrically arranged with respect to the center line of the positioning horizontal plate 4 and is vertically fixedly connected with the positioning horizontal plate 4. When the first servo motor 4012 is turned on to rotate the adjusting roller shaft 4011, the gear vertical plate 401 meshing with the adjusting roller shaft 4011 can be driven to move up and down.

[0028] Embodiment 2 See also Figure 1 , Figure 2 , Figure 7 and Figure 8 The present invention provides a technical solution: a protective outer frame 5 is installed on the upper end of the fixed installation plate 1, an adjusting disk 502 is arranged on the inner side of the upper end of the protective outer frame 5, a movable inner gear sleeve 503 connected to the protective outer frame 5 is arranged on the outer side of the adjusting disk 502, and a welding head 508 connected by a telescopic rod 506 is arranged below the movable inner gear sleeve 503; Furthermore, teeth are provided on the inner side of the upper end of the movable inner gear sleeve 503, and the movable inner gear sleeve 503 and the adjusting disk 502 are connected by a snap-fitting engagement. The receiving base plate 504 fixedly connected to the lower end of the movable inner gear sleeve 503 forms a fitting circular motion within the protective outer frame 5, which can enable the movable inner gear sleeve 503 to perform stable rotational motion within the protective outer frame 5 and avoid being separated from the connection state with the protective outer frame 5.

[0029] Furthermore, reserved holes 505 are evenly opened on the lower surface of the receiving base plate 504 for threaded connection with the telescopic rod 506 through the second adjusting bolt 507, so that the angle and orientation can be adjusted according to the actual diameter size of the two-phase flow meter component.

[0030] Specifically, in combination with the first embodiment, after the limiting clamp block 407 positions and clamps the components of the two-phase flowmeter, the docking diameter size of the components of the two-phase flowmeter is manually measured. The lower surface of the receiving bottom plate 504 is uniformly provided with reserved hole grooves 505, and the telescopic rod 506 is connected to the receiving bottom plate 504 by a threaded manner through the second adjusting bolt 507. It can adjust and install the welding head 508 according to the docking diameter size of the components, so as to adapt to the annular welding requirements of the two-phase flowmeter. After that, when the telescopic rod 506 is opened to extend the welding head 508, the welding operation can be carried out on the connection part of the two-phase flowmeter. Among them, the model of the welding head 508 is: water-cooled welding gun head, MIG: Binzel MB36KW(350A); In addition, the movable internal gear sleeve 503 is vertically and fixedly connected to the receiving bottom plate 504, and the movable internal gear sleeve 503 is connected to the adjusting disk 502 in a snap-fit meshing manner. When the third servo motor 501 is opened to rotate the adjusting disk 502, it can drive the movable internal gear sleeve 503 that is snap-fit meshed with the adjusting disk 502 to generate a circumferential rotational movement. At this time, an integrated structure is formed between the adjusting disk 502 and the movable internal gear sleeve 503, and its snap-fit meshing connection is a relatively fixed connection, and the receiving bottom plate 504 fixedly connected to the lower end of the movable internal gear sleeve 503 performs a fitting rotational movement inside the upper end of the protective outer frame 5, so that the receiving bottom plate 504 drives the welding head 508 to perform a circular movement around the center point of the connection part of the two-phase flowmeter, so as to facilitate uniform welding, reduce the generation of welding spots, and improve the welding effect. Through the snap-fit meshing connection between the adjusting disk 502 and the movable internal gear sleeve 503, during use, the movable internal gear sleeve 503 will rotate synchronously and in the same direction under the snap-fit connection state of the adjusting disk 502. And during later disassembly, the movable internal gear sleeve 503 can be directly separated from the adjusting disk 502 and separated from the third servo motor 501 to avoid damage caused by disassembly of electrical equipment. Among them, the structure between the movable internal gear sleeve 503 and the convex structure provided on the upper side of its outer end is a detachable structure.

[0031] Embodiment 3 Please refer to Figure 1 、 Figure 2 、 Figure 3 and Figure 4 In, the present invention provides a technical solution: a fixed installation base plate 1 is provided, and a first limiting groove 2 for cooling and cooling the welded two-phase flowmeter is provided below the fixed installation base plate 1. Atomizing nozzles 308 are provided on the inner sides of the front and rear ends of the first limiting groove 2; Furthermore, second limit grooves 303 are provided on the inner sides of both left and right ends of the cooling box body 3, and the second limit grooves 303 are arranged to correspond to the first limit grooves 2 provided on the left and right sides of the fixed mounting plate 1, so that the first limit grooves 2 and the second limit grooves 303 can be adjacent to each other, which is convenient for the positioning cross plate 4 to slide without difference when moving up and down.

[0032] Furthermore, water tanks 304 are fixedly installed at both the front and rear ends of the cooling box body 3. The lower end of the water tank 304 is connected to the booster box 306 arranged outside the atomizing nozzle 308 through a connecting hose 307, which can facilitate water circulation when the booster box 306 moves horizontally forward and backward.

[0033] Furthermore, the left and right ends of the boost box 306 are fitted to the inner walls of the left and right ends of the cooling box 3, and the boost box 306 is moved back and forth in the cooling box 3 through the telescopic cylinder 305. After the telescopic cylinder 305 is opened to displace the boost box 306, the inner surface of the atomizing nozzle 308 can be more closely fitted to the outer surface of the two-phase flow meter component.

[0034] Specifically, in combination with the first and second embodiments, the extension plate arranged in the middle of the limiting clamp block 407 has front and rear dimensions and left and right dimensions that are larger than the interface dimensions of the giving way groove 402, so that better shielding and blocking can be performed when the limiting clamp block 407 moves left and right, and impurities can be prevented from entering. At the same time, when the welding is completed, the first servo motor 4012 is turned on to rotate the adjusting roller shaft 4011, so as to drive the gear vertical plate 401 meshing with the adjusting roller shaft 4011 to perform lifting and lowering movements as a whole. At this time, the positioning horizontal plate 4 will continue to descend through the first limiting groove 2 and the second limiting groove 303 under the convex structures fixedly installed at the left and right ends, and the upper end of the gear vertical plate 401 is set to protrude outward. When the positioning horizontal plate 4 is lowered to the specified position, the adjusting roller shaft 4011 can be fitted at the protruding position of the upper end of the gear vertical plate 401 to achieve the role of limiting, so as to prevent the positioning horizontal plate 4 from continuously descending and make the gear vertical plate 401 disengaged from the meshing state with the adjusting roller shaft 4011. In addition, water storage tanks 304 are fixedly installed on the upper sides of the front and rear ends of the cooling box 3, and the water storage tank 304 forms a communication structure with the booster box 306 through the connecting hose 307. When the positioning cross plate 4 is lowered into the cooling box 3 with the welded two-phase flow meter component, the connecting hose 307 is opened to drive the booster box 306 to move inward as a whole, and finally the atomizing nozzle 308 is opened to perform atomization cooling and cooling on the welded two-phase flow meter component. Among them, since the lower side of the interior of the cooling box 3 is inclined inward, it is convenient to statistically discharge the accumulated sewage later after finally opening the water stopper 301, and it is also possible to disassemble the first adjusting bolt 302 later and disassemble the cooling box 3 as a whole to rinse the interior of the cooling box 3 to avoid dirt residue; Among them, the model of the booster set in the booster tank 306 is: Cat Pumps 3611; the model of the atomizing nozzle 308 is: Lechler 6004 fan-shaped atomizing nozzle.

[0035] The above has described an embodiment of the present invention in detail, but the content is only the preferred embodiment of the present invention and cannot be considered as limiting the scope of implementation of the present invention. All equivalent changes and improvements made according to the scope of the present invention application shall still fall within the scope covered by the patent of the present invention.
