Description

Technical Field

[0001] This utility model belongs to the field of straight and bent pipe structure assembly technology, specifically relating to a multifunctional straight and bent pipe assembly fixture. Background Technology

[0002] In blast furnace ironmaking, the straight and curved blast furnace blast pipes are crucial high-temperature and high-pressure pipeline components connecting the hot blast main pipe to the blast furnace tuyeres. Their installation quality directly affects the efficiency of the blast system and the stability of blast furnace operation. To ensure a reliable airtight connection with the upstream and downstream pipeline systems and correct spatial positioning, after the straight and curved pipes are manufactured, a precise docking and assembly process between the straight and curved pipes is usually required in the manufacturing workshop or a specific site.

[0003] However, because straight and curved air supply pipes are typically made of heavy cast steel or welded components, with large structural dimensions, offset centers of gravity, and irregular shapes, they are highly susceptible to lateral displacement or overturning due to gravity or even slight external forces during critical horizontal flange-to-flange connections. This instability during the connection process can easily lead to poor operational stability during the assembly phase after production, affecting work efficiency and safety. Utility Model Content

[0029] An embodiment of this utility model provides a multifunctional straight and bent pipe assembly fixture, including: a support frame 1, which extends horizontally; a sliding component 2, which is slidably mounted on the support frame 1 and configured to reciprocate horizontally; and a connecting plate 3, which is located on one side of the support frame 1 and connected to the sliding component 2. The connecting plate 3 has at least one pair, and any pair of connecting plates 3 are brought closer or further apart by the sliding component 2 and are configured to cooperate with each other and be detachably connected to the side pipe connecting seat 41 of the bent pipe 4 so that the main pipe 42 of the bent pipe 4 remains vertically extended.

[0030] Specifically, the sliding component 2 can be a rolling structure such as a wheel or a sliding structure such as a slider.

[0031] In this embodiment, as Figure 1 As shown, a multi-functional straight-bend pipe assembly fixture is constructed from a support frame 1, a sliding assembly 2, and a connecting plate 3. The support frame 1 extends horizontally and can be stably placed on the ground, ensuring stability. The sliding assembly 2 is slidably mounted on the support frame 1 and can slide back and forth horizontally. The connecting plate 3 is placed on one side of the support frame 1 and connected to the sliding assembly 2, allowing the sliding assembly 2 to move back and forth on the support frame 1, flexibly adjusting its position. With this configuration, the connecting plate 3 can be detachably connected to the side pipe connecting seat 41 of the bend 4, keeping the side pipe connecting seat 41 perpendicular to the ground. The vertical direction of the side pipe connecting seat 41 is parallel to the axis of the main pipe 42 of the bend 4, which is also perpendicular to the ground. This ensures that the main pipe 42 of the bend 4 extends vertically. Maintaining the stability of the main pipe 42 prevents tipping or displacement, facilitating the lifting of straight pipes above the main pipe 42 for assembly, and effectively improving the stability of straight and bent pipe assembly. Furthermore, at least one pair of connecting plates 3 are provided. Any pair of connecting plates 3 can move closer or further apart via the sliding assembly 2, allowing two connecting plates 3 to connect to a side pipe connecting seat 41, further ensuring the stability of the bent pipe 4. Simultaneously, the position between the two connecting plates 3 can be flexibly adjusted, facilitating connection with side pipe connecting seats 41 of different sizes, thus expanding the applicability. In addition, at least one pair of connecting plates 3 can connect to at least one side pipe connecting seat 41, thereby connecting at least one bent pipe 4 to the support frame 1, facilitating the movement of at least one bent pipe 4 via the lifting support frame 1, and improving lifting efficiency.

[0032] Optionally, the connecting plate 3 has a strip hole 31 on its surface facing the side tube connecting seat 41. The strip hole 31 penetrates the connecting plate 3 and extends vertically. The surface of the connecting plate 3 is fitted to the bottom surface of the side tube connecting seat 41 and is detachably connected to the side tube connecting seat 41 through the connecting structure 32 that penetrates the strip hole 31.

[0033] In this optional embodiment, in order to improve the connection stability between the side tube connector 41 and the connecting plate 3, such as Figure 1 and Figure 2 As shown, the connecting plate 3 has a strip hole 31 on its surface facing the side tube connecting seat 41. The strip hole 31 penetrates the connecting plate 3 and extends vertically. The surface of the connecting plate 3 is fitted to the bottom surface of the side tube connecting seat 41. The connecting structure 32, which penetrates the strip hole 31, is detachably connected to the side tube connecting seat 41. By adjusting the position of the connecting structure 32 in the strip hole 31, the connecting structure 32 can be connected to a suitable position on the side tube connecting seat 41, or to side tube connecting seats 41 of different sizes, thereby effectively improving the connection stability between the side tube connecting seat 41 and the connecting plate 3.

[0034] Optionally, the connecting structure 32 includes a bolt 321, a washer 322, and a nut 323. The washer 322 is attached to the side wall of the side tube connecting seat 41 away from the connecting plate 3. One end of the bolt 321 passes through the washer 322, the side tube connecting seat 41, and the strip hole 31 in sequence. The nut 323 is fitted on one end of the bolt 321 and cooperates with the side tube connecting seat 41 to clamp the connecting plate 3. The nut on the other end of the bolt 321 cooperates with the side tube connecting seat 41 to clamp the washer 322.

[0035] In this optional embodiment, such as Figure 2 and Figure 3 As shown, a connecting structure 32 is formed by bolt 321, washer 322, and nut 323. The washer 322 is attached to the side wall of the side tube connecting seat 41 away from the connecting plate 3. One end of the bolt 321 passes through the washer 322, the side tube connecting seat 41, and the slot 31 in sequence. The nut 323 is fitted on one end of the bolt 321 and cooperates with the side tube connecting seat 41 to clamp the connecting plate 3. The nut on the other end of the bolt 321 cooperates with the side tube connecting seat 41 to clamp the washer 322. At this time, the setting of the washer 322 can ensure the contact area between the nut and the side plate connecting seat 41, avoiding excessive pressure that could damage the side plate connecting seat 41. The connection between the bolt 321 and the nut 323 can ensure the clamping and fixing force of the connecting component 32 on the side plate connecting seat 41 and the connecting plate 3, thereby ensuring the connection stability between the side plate connecting seat 41 and the connecting plate 3.

[0036] Optionally, the support frame 1 includes a support plate 11 and a support column 12. The support plate 11 extends horizontally and there are two support plates 11. The two support plates 11 are parallel to each other and are spaced apart in the vertical direction. The two ends of the support column 12 are respectively connected to the two support plates 11. The sliding assembly 2 is slidably installed on the support plate 11.

[0037] In this optional embodiment, such as Figure 1 and Figure 2As shown, a support frame 1 is formed by a support plate 11 and a support column 12. The support plate 11 extends horizontally, and the sliding component 2 is slidably installed on the support plate 11 to ensure the sliding stability and installation stability of the sliding component 2. On this basis, two support plates 11 are set, which are parallel to each other and distributed vertically at intervals. The two ends of the support column 12 are connected to the two support plates 11 respectively, so that the support plate 11 and the support column 12 form a frame structure to ensure the structural stability of the support frame 1, and thus ensure the lateral support of the bend 4.

[0038] Optionally, the support frame 1 further includes a reinforcing member 13, which is located at the connection between the support plate 11 and the support column 12 and is connected to the support plate 11 and the support column 12 respectively.

[0039] In this optional embodiment, in order to further ensure the structural stability of the support frame 1, such as Figure 1 and Figure 2 As shown, the support frame 1 is also provided with a reinforcing member 13. The reinforcing member 13 can be provided at the connection between the support plate 11 and the support column 12, thereby enhancing the structural strength of the connection and improving the structural stability. At the same time, the reinforcing member 13 is connected to the support plate 11 and the support column 12 respectively, thereby effectively improving the connection stability between the support plate 11 and the support column 12, and further ensuring the structural stability of the support frame 1.

[0040] Optionally, the edge of the support plate 11 extends upward to form a retaining edge 111. The retaining edge 111 extends horizontally. The sliding assembly 2 includes a moving wheel 21 and a guide wheel 22. The moving wheel 21 is rolled on the top wall of the retaining edge 111. There are two guide wheels 22, and the wheel diameter is larger than that of the moving wheel 21. The two guide wheels 22 are respectively arranged on both sides of the moving wheel 21 and are coaxially arranged with the guide wheel 22. The guide wheel 22 is connected to the connecting plate 3.

[0041] In this optional embodiment, such as Figure 1 and Figure 2As shown, to ensure the stability of the moving component 2, the edge of the support plate 11 extends upward to form a retaining edge 111. The retaining edge 111 extends horizontally and is equipped with a moving wheel 21 and a guide wheel 22 to form the sliding component 2. The moving wheel 21 is rolled on the top wall of the retaining edge 111. There are two guide wheels 22, and their diameters are larger than those of the moving wheel 21. The two guide wheels 22 are respectively arranged on both sides of the moving wheel 21 and are coaxial with the guide wheels 22. With this arrangement, the moving wheel 21 can roll on the retaining edge 111 to achieve the sliding of the moving component 2. While the moving wheel 21 is rolling, the two guide wheels 22 cooperate with the retaining edge 111 to ensure that the rolling path of the moving wheel 21 does not deviate, thereby ensuring the stability of the moving component 2. On this basis, the guide wheels 22 are connected to the connecting plate 3, so that while the moving wheel 21 is rolling, the connecting plate 3 can be moved by the guide wheels 22, thereby achieving flexible adjustment of the position of the connecting plate 3.

[0042] Optionally, the upper end of the connecting plate 3 is connected to the guide wheel 22 on one side of the movable wheel 21 on the sidewall of the support plate 11 above, away from the sidewall of the side tube connecting seat 41. The upper end of the connecting plate 3 bends and extends in the direction away from the side tube connecting seat 41, extends to cover the top of the sliding assembly 2, then bends and extends downward, extends to the inner side of the sidewall 111 after covering the guide wheel 22 on the other side of the movable wheel 21, and is connected to the guide wheel 22 on the other side of the movable wheel 21.

[0043] In this optional embodiment, such as Figure 1 and Figure 2 As shown, to ensure the stability of the connecting plate 3's movement, the upper end of the connecting plate 3, away from the side wall of the side tube connecting seat 41, is connected to the guide wheel 22 on one side of the moving wheel 21 on the sidewall 111 of the support plate 11 above. At the same time, the upper end of the connecting plate 3 bends and extends in the direction away from the side tube connecting seat 41, extending to cover the top of the sliding component 2 and then bending downwards, extending to the inner side of the sidewall 111 after covering the guide wheel 22 on the other side of the moving wheel 21, and connecting with the guide wheel 22 on the other side of the moving wheel 21. With this configuration, the upper end of the connecting plate 3 forms a downward-opening n-shaped structure. The two sides of the upper end are connected to the two guide wheels 22 respectively, ensuring that the connecting plate 3 moves with the sliding component 2. At the same time, the two sides of the upper end of the connecting plate 3 interfere with the inner and outer sides of the sidewall 111 respectively, preventing the connecting plate 3 from deviating from the moving track during movement and ensuring the stability of the connecting plate 3's movement.

[0044] Optionally, the lower end of the connecting plate 3 is connected to the guide wheel 22 on the side of the movable wheel 21 on the sidewall of the side tube connecting seat 41 away from the side wall of the support plate 11 located below, and extends downward to the outside of the sidewall 111.

[0045] In this optional embodiment, such as Figure 1 and Figure 2 As shown, in order to further ensure the connection stability and movement stability of the connecting plate 3, the lower end of the connecting plate 3, away from the side wall of the side tube connecting seat 41, is connected to the guide wheel 22 on the side of the moving wheel 21 on the edge 111 of the support plate 11 below, and extends downward to the outside of the edge 111. Thus, the connecting plate 3 is connected by the sliding components 2 on the upper and lower support plates 11, ensuring the connection stability of the connecting plate 3, thereby improving the placement stability of the bend 4. At the same time, the upper and lower sliding components 2 move synchronously, which can effectively improve the movement flexibility and stability of the connecting plate 3.

[0046] Optionally, a protective plate 33 is connected to the lower end of the connecting plate 3 away from the side wall of the side tube connecting seat 41. The protective plate 33 covers the top of the sliding assembly 2 and bends downward, extending to the inner side of the stop 111 after covering the guide wheel 22 on the other side of the moving wheel 21, and is connected to the guide wheel 22 on the other side of the moving wheel 21.

[0047] In this optional embodiment, such as Figure 1 and Figure 2 As shown, in order to further improve the moving stability of the connecting plate 3, a protective plate 33 is connected to the lower end of the connecting plate 3 away from the side wall of the side tube connecting seat 41. The protective plate 33 covers the top of the sliding component 2 and bends downward, extending to the inner side of the baffle 111 after covering the guide wheel 22 on the other side of the moving wheel 21, and is connected to the guide wheel 22 on the other side of the moving wheel 21. With this configuration, the lower end of the connecting plate 3 can form an h-shaped structure. The two sides of the lower end of the connecting plate 3 are respectively connected to two guide wheels 22 and extend to the two sides of the baffle 111. In this way, through the mutual cooperation of the guide wheels 22 and the cooperation of the two sides of the lower end of the connecting plate 3 with the baffle 111, the moving stability of the connecting plate 3 can be guaranteed, and the movement of the connecting plate 3 can be prevented from deviating from the track.

[0048] Optionally, the connecting plate 3 has two sets, each set of connecting plates 3 has at least one pair, and the two sets of connecting plates 3 are located on opposite sides of the support frame 1.

[0049] In this optional embodiment, in order to improve the assembly efficiency of the bend 4 and the straight pipe, such as Figure 1 and Figure 2 As shown, there are two sets of connecting plates 3, each set of connecting plates 3 having at least one pair. The two sets of connecting plates 3 are located on opposite sides of the support frame 1. With this arrangement, multiple bends 4 can be connected to the two sides of the support frame 1 through the paired connecting plates 3, which can simultaneously realize the assembly of multiple bends 4 and straight pipes, effectively improving work efficiency. Moreover, the multiple bends 4 are distributed in pairs on both sides of the support frame 1, which can effectively improve the placement stability of the support frame 1 and the bends 4 through symmetrical effect.
