Description

Technical Field

[0001] This utility model belongs to the technical field of welding equipment, specifically relating to an auxiliary device for assembling large non-standard furnace body panels. Background Technology

[0002] The installation of large non-standard furnace bodies mainly consists of several parts, including the top-blown shell, thermocouple installation, and brickwork. The shell is divided into a bottom plate and surrounding plates. The surrounding plates are further divided into upper and lower plates. The steel plates of the upper and lower surrounding plates are rolled and then welded together. The side welds must be flat, and the upper and lower surrounding plates must be internally aligned and flat. However, current technology often relies on manual alignment by operators during welding, which requires a large amount of manpower. Furthermore, manual alignment demands a high level of experience from the operators. If the excess height is too high, it will create sharp geometric abrupt changes, which can easily lead to fatigue cracks under alternating loads, such as thermal expansion and contraction of the furnace body. Excessive flatness of the surrounding plates will affect the furnace's sealing performance, causing high-temperature gas leakage. Utility Model Content

[0003] This utility model proposes an auxiliary device for assembling large non-standard furnace body panels, which aims to solve the deviations that occur during the welding of large non-standard furnace body shell panels and reduce manpower output.

[0004] A large non-standard furnace body enclosure assembly auxiliary device is characterized by comprising an arc-shaped clamping plate, a connecting plate, bolts, a sleeve, and a double-threaded nut. The connecting plate is trapezoidal, with its long base being arc-shaped, and its curvature matching the outer curvature of the large non-standard furnace body enclosure. The short base of the connecting plate is fixed to the top of the outer side of the sleeve, and the inner side of the sleeve is fixed to the bolts. The inner side of the double-threaded nut is symmetrically provided with threads in opposite directions, and two bolts are symmetrically threaded into the double-threaded nut. The bottom edge of the arc-shaped clamping plate is arc-shaped, and its curvature matches the inner curvature of the large non-standard furnace body enclosure. A semi-circular hole is provided at the center of the bottom of the arc-shaped clamping plate.

[0005] Furthermore, a circular hole is formed on the outer wall of the double-grooved nut, and a torque rod is inserted into the circular hole to push the torque rod to rotate the double-grooved nut.

[0006] The beneficial effects of this utility model are as follows: When welding the enclosure panels together, an arc-shaped clamping plate is welded to the inner side of the two enclosure panels, while connecting plates are welded to the outer side of the enclosure panels. By rotating the double-threaded nut, the two bolts are brought closer together, causing the connecting plate to gradually tighten the two enclosure panels and form a stable state. Through the design of the arc-shaped clamping plate matching the curvature of the inner side of the enclosure panel, combined with the adjustment structure of the outer connecting plate and the double-threaded nut, bidirectional positioning and clamping of the inner and outer sides of the enclosure panels are achieved. The double-threaded nut drives the bolts to move synchronously, which can precisely adjust the spacing and flatness between the enclosure panels, effectively avoiding the flatness deviation problem of traditional manual alignment, ensuring that the joints of the enclosure panels are flat after welding, improving the furnace body's sealing performance, and preventing high-temperature gas leakage. The device automatically aligns through a mechanical structure, replacing manual adjustment that relies on experience, reducing the need for highly skilled operators. Using a torque rod to rotate the double-threaded nut makes operation simple and labor-saving, significantly reducing labor intensity, shortening welding preparation time, and improving overall efficiency. Precise alignment avoids geometrical abrupt changes in weld reinforcement, reducing the risk of fatigue cracks in the furnace body under alternating thermal expansion and contraction loads. Enhanced welding quality stability further guarantees the structural strength and service life of large, non-standard furnace bodies. The arc-shaped clamping plate and connecting plate's curvature match the inner and outer contours of the enclosure, ensuring a good fit with enclosures of different sizes and expanding its applicability. The overall structure is simple and compact, facilitating installation and reuse, and possesses high engineering practical value. Attached Figure Description

[0009] Example 1: An auxiliary device for assembling a large non-standard furnace body enclosure includes an arc-shaped clamping plate 1, a connecting plate 2, bolts 3, a sleeve 4, and a double-threaded nut 5. The connecting plate 2 is trapezoidal, with its long base being arc-shaped, and its curvature matching the outer curvature of the large non-standard furnace body enclosure 6. The short base of the connecting plate 2 is fixed to the top of the outer side of the sleeve 4. The inner side of the sleeve 4 is fixed to the bolts 3. The inner side of the double-threaded nut 5 is symmetrically provided with threads in opposite directions, and two bolts 3 are symmetrically threaded into the double-threaded nut 5. The bottom edge of the arc-shaped clamping plate 1 is arc-shaped, and its curvature matches the inner curvature of the large non-standard furnace body enclosure 5. A semi-circular hole 11 is provided at the center of the bottom of the arc-shaped clamping plate 1.

[0010] A circular hole 51 is opened on the outer wall of the double-grooved nut 5, and a torque rod 52 is inserted into the circular hole 51. Pushing the torque rod 52 causes the double-grooved nut 5 to rotate.

[0011] In use, the bottom surface of the arc-shaped clamping plate is welded to the inner side of the two rolled-up surrounding plates 6, while the connecting plates 2 are welded to the outer side of the surrounding plates 5 respectively. By rotating the double-threaded nut 5, the two bolts 3 are brought closer together, which drives the connecting plates 2 to gradually tighten the two surrounding plates 6 and form a stable state. During the process of the surrounding plates 6 approaching, the arc-shaped clamping plate 1 will deform, and the semi-circular hole 11 can ensure that it can deform. After the surrounding plates 6 are welded together, the device can be cut off from the surrounding plates 6 or left on the surrounding plates 6 to strengthen its connection and tightness.
