Abstract
Description
Technical Field
[0001] This invention relates to the field of economizer serpentine tube welding technology, specifically to a deformation-resistant economizer serpentine tube welding support fixture. Background Technology
[0002] The economizer utilizes the waste heat of the flue gas at the boiler tail end to heat the feedwater, thereby improving boiler efficiency, reducing flue gas temperature, and decreasing heat loss and fuel consumption. The serpentine tube design ensures that the flue gas fully contacts the pipe surface, effectively absorbing the dissipated heat and thus improving heat exchange efficiency. The economizer serpentine tube welding process employs manual TIG welding, mechanical TIG and MIG welding, or mechanical hot wire TIG welding to ensure the quality of the weld joint and prevent leakage.
[0003] Currently, the stability of the welding support fixture itself is limited. Due to its high weight, the long-term placement of the economizer serpentine tube can easily cause the support fixture to shake or even tip over, reducing safety and stability.
[0004] Therefore, a novel anti-deformation economizer serpentine tube welding support fixture is proposed to solve the above problems. Summary of the Invention
[0005] The purpose of this invention is to provide a welding support fixture for economizer serpentine tubes that prevents deformation, in order to solve the problem that the welding support fixtures mentioned in the background art have limited stability and that the economizer serpentine tubes, due to their high weight, are prone to shaking or even tipping over after long-term placement, thus reducing safety and stability.
[0006] To achieve the above objectives, the present invention provides the following technical solution: a deformation-resistant economizer serpentine tube welding support fixture, comprising a base, wherein limit side plates are vertically arranged on both sides of the top of the base, and a deformation-resistant reinforcing component is provided at the outer end of the base; The reinforcement component includes a buffer and shock-absorbing pad, and two sets of the buffer and shock-absorbing pad are provided and fixedly connected to the front end and rear end of the base respectively. Two sets of fixing brackets are fixedly connected to the front end and rear end of the base. The two sets of fixing brackets are located on both sides of the buffer and shock-absorbing pad and are sleeved and fixed to the outside of both sides of the buffer and shock-absorbing pad. Connecting brackets are fixedly connected to both sides of the buffer and shock-absorbing pad, and the two sets of connecting brackets are sleeved and fixed to the outer end of the bottom of the base. As a further technical solution of the present invention, an outer plate is fixedly connected to the rear of both sides of the base. A fixing plate is fixedly connected vertically to the top of the outer plate of the base. A connecting block is fixedly connected to the top of the inner side of the fixing plate. An auxiliary plate is horizontally arranged above the base. A sliding outer plate is horizontally fixedly connected to the rear end of the limiting side plate. Two sets of fastening bolts are arranged through the inside of the auxiliary plate. A handwheel is fixedly connected to the rear end of the fastening bolts.
[0007] As a further technical solution of the present invention, the two sides of the auxiliary plate are respectively fixedly connected to the side walls of two sets of connecting blocks, and the two sides of the front end of the auxiliary plate are laterally fixedly connected to slide rails. The rear end of the sliding outer plate is provided with a groove, and the sliding outer plate is sleeved on the outside of the slide rail, and the inner wall of the groove and the outside of the slide rail form a sliding connection.
[0008] As a further technical solution of the present invention, a protective inner pad is fitted to the inner side of the limiting side plate, two sets of first mounting seats are fixedly connected to the top of the limiting side plate, and second mounting seats are fixedly connected to the bottom of the front end and the rear end of the limiting side plate.
[0009] As a further technical solution of the present invention, the top, front, and bottom of the rear end of the protective inner pad are all fixedly connected with right-angle brackets, and the right-angle brackets correspond one-to-one with the first mounting base and the second mounting base, and the right-angle brackets are inserted into the interior of the first mounting base and the second mounting base.
[0010] Compared with the prior art, the beneficial effects of the present invention are: the anti-deformation economizer serpentine tube welding support tooling not only realizes the anti-deformation support function and the limiting and fixing function, but also realizes the strong protection function. (1) By setting up buffer damping pads, fixed frames, connecting frames, stable platforms and support plates, the addition of two sets of buffer damping pads can effectively absorb and disperse the impact force, reduce the vibration and damage of the base. The two sets of connecting frames are connected and fixed to the outer end of the base to strengthen the firmness between the buffer damping pads and the base, effectively preventing the buffer damping pads from loosening or even falling off. The fixed frames limit and fix the buffer damping pads, strengthening the connection between the buffer damping pads and the base. The stable platform and support plates work together to provide strong support to the bottom of the base, effectively preventing the base from deforming due to the excessive weight of the economizer serpentine tube. (2) By setting a fixed plate, an auxiliary plate, a slide rail, a sliding outer plate, a groove, fastening bolts and a handwheel, the two sets of limiting side plates can play a role in limiting and fixing the two sides of the economizer serpentine tube. The sliding outer plate is sleeved and installed outside the slide rail. The sliding connection method ensures that the slide rail moves stably in the groove, which not only improves the stability of the limiting side plate during movement, but also strengthens the connection between the limiting side plate and the auxiliary plate, effectively preventing the limiting side plate from shifting. (3) By providing a protective inner pad, a first mounting base, a second mounting base and a right angle bracket, the protective inner pad is placed close to the inner wall of the limiting side plate, which provides strong protection for the surface of the limiting side plate, avoids wear on the surface of the limiting side plate caused by long-term clamping, and effectively extends the service life of the limiting side plate. At the same time, the right angle bracket is fixed inside the first mounting base and the second mounting base by means of plug-in connection, which improves the flexibility of the protective inner pad and makes it easy to disassemble and replace it.

A stabilizing platform 13 is fixedly connected to both sides of the bottom end of the base 4, and a support plate 2 is fixedly connected to the bottom end of the stabilizing platform 13. Specifically, such as Figure 1 and Figure 2As shown, by adding two sets of buffer and shock-absorbing pads 1 during use, the impact force can be effectively absorbed and dispersed, reducing the vibration and damage of the base 4. Two sets of connecting brackets 3 are sleeved and fixed to the outer end of the base 4 to strengthen the firmness between the buffer and shock-absorbing pads 1 and the base 4, effectively preventing the buffer and shock-absorbing pads 1 from loosening or even falling off. The buffer and shock-absorbing pads 1 are limited and fixed by the fixing bracket 14 to strengthen the connection between the buffer and shock-absorbing pads 1 and the base 4. The stabilizing platform 13 and the support plate 2 work together to provide strong support for the bottom of the base 4, effectively preventing the base 4 from deforming due to the excessive weight of the economizer serpentine tube.
[0015] Both sides of the base 4 are fixedly connected to the rear of the outer plate 18. The top of the base 4 and the outer plate 18 are fixedly connected to the fixing plate 5 vertically. The top of the inner side of the fixing plate 5 is fixedly connected to the connecting block 6. The base 4 is horizontally provided with the auxiliary plate 7 above it.

[0017] Working principle: In use, the protective inner pad 9 is placed against the inner wall of the limiting side plate 8. The right-angle bracket 15 is fixed inside the first mounting base 11 and the second mounting base 17 by a plug-in connection. The sliding outer plate 12 is slidably installed outside the slide rail 10 through the groove 16. The two sets of limiting side plates 8 are pushed inward stably until the two sides of the economizer serpentine tube are limited and fixed. After rotating the handwheel 19 in sequence, the internal parts of the auxiliary plate 7 and the limiting side plate 8 are moved by the fastening bolt 20, and the limiting side plate 8 is fixed in the current position. By adding two sets of buffers... The shock-absorbing pad 1 can effectively absorb and disperse the impact force, reducing the vibration and damage of the base 4. It is fixed to the outer end of the base 4 by two sets of connecting brackets 3, which strengthens the firmness between the shock-absorbing pad 1 and the base 4, effectively preventing the shock-absorbing pad 1 from loosening or even falling off. The shock-absorbing pad 1 is limited and fixed by the fixing bracket 14, which strengthens the connection between the shock-absorbing pad 1 and the base 4.
