Description

Technical Field

[0001] This utility model belongs to the technical field of ceramic-lined composite steel pipe, specifically relating to a ceramic-lined composite steel pipe with a flange. Background Technology

[0002] Ceramic-lined composite steel pipe is a type of steel pipe with a ceramic lining on its inner wall. This composite steel pipe combines the strength of steel pipe with the wear resistance and corrosion resistance of ceramics, and is widely used in industries such as mining, metallurgy, power, and coal to transport highly abrasive and corrosive materials or fluids.

[0003] Patent CN223511711U describes a ceramic-lined composite steel pipe with a flange. The flange can be used for connecting and installing the composite steel pipe. Through the rotatable connection between the flange and the ceramic-lined composite steel pipe body, the flange can rotate. During the flange docking installation process, there is no need to rotate the ceramic-lined composite steel pipe body, making docking installation more convenient. Furthermore, through the insertion of balls and grooves, the relative position of the flange and the ceramic-lined composite steel pipe body can be fixed, which can prevent the flange from rotating arbitrarily to a certain extent and improve the stability during docking. However, its structure needs to be installed inside the flange, which increases the manufacturing difficulty. Utility Model Content

[0004] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a ceramic-lined composite steel pipe with a flange, which has the advantage of easy positioning.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a ceramic-lined composite steel pipe with a flange, comprising a pipe body, wherein positioning components are provided on both outer walls of the pipe body, the positioning components comprising a connecting rod, a hook, an insert rod, a pull rod and a base, the insert rod and the connecting rod being connected by a hook, the pull rod being threadedly connected to the base, the pull rod being rotatably connected to the insert rod and supported at the bottom of the insert rod, and the insert rod bridging two hooks.

[0006] The above technical solution can facilitate positioning. After the positioning component is installed between the pipe bodies of the two flanges, the positioning holes of the two flanges will be aligned. By rotating the pull rod, the two pipe bodies can be temporarily fixed, which makes it convenient for a user to bolt the flanges, thus facilitating fixation. At the same time, the positioning component can be removed, so as not to add extra components to the pipe body, and the positioning component can also be reused.

[0007] Preferably, the hook includes a hook body, a first connector is fixedly connected to the outer wall of the hook body, and a second connector is fixedly connected to the outer wall of the hook body.

[0008] The above technical solution facilitates assembly. The hook body can bridge the connecting rod and the insertion rod through the second connector, while the first connector can be used to install accessories.

[0009] Preferably, the pull rod includes a rod body, the bottom of the rod body is provided with a threaded head, a clamping plate is fixedly connected to the outer wall of the rod body, and a rotating wheel is fixedly connected to the top outer wall of the rod body.

[0010] The above technical solution can achieve a control effect. By rotating the wheel, the rod can be raised and lowered on the base, so that the clamping plate can apply pressure to the rod, thereby controlling the two hooks to move closer or further apart.

[0011] Preferably, the base includes a sleeve, and a fork plate is fixedly connected to the bottom outer wall of the sleeve, and the bottom of the fork plate is treated with anti-slip treatment.

[0012] The above technical solution can provide support. The sleeve can be used to connect with the first thread of the rod. When the friction at the bottom of the fork plate is insufficient, it can be limited by the connecting rods on both sides to prevent it from rotating.

[0013] Preferably, an accessory can be added between the two hooks. The accessory includes a middle block with a screw hole on its inner wall and side rods rotatably connected to the outer walls on both sides of the middle block.

[0014] The above technical solution facilitates connection. With the addition of accessories, the positioning components can be integrated into a whole, allowing the structure to be connected after unloading, thus facilitating relocation.

[0015] Preferably, the thread on the inner wall of the screw hole is opposite in direction to the thread on the bottom of the rod, and the corresponding thread is provided on the outer wall of the pull rod.

[0016] The above technical solution facilitates fixation. The rod and screw holes prevent the positioning component from shaking after disassembly, thus making it easy to move the positioning component.

[0017] Preferably, the outer wall of the tube is provided with a connecting lug for connecting the connecting rod, and the position of the connecting lug avoids the connecting hole of the flange.

[0018] The above technical solution facilitates installation, and the connecting rod avoids the flange hole, thus preventing interference with the mounting bolts.

[0019] Compared with the prior art, the beneficial effects of this utility model are: 1. After the positioning assembly is installed between the pipe bodies of the two flanges, the positioning holes of the two flanges will be aligned. By rotating the tie rod, the two pipe bodies can be temporarily fixed. This makes it convenient for one user to bolt the flanges, thus facilitating fixation. At the same time, the positioning assembly can be removed, so as not to add extra components to the pipe body, and also to facilitate the repeated use of the positioning assembly.

[0020] 2. The hook body can bridge the hook connecting rod and the insert rod through the second connector. The first connector can be used to install accessories. By rotating the wheel, the rod body can be raised and lowered on the base. In this way, the clamping plate can apply pressure to the insert rod, thereby controlling the two hook bodies to move closer or further apart. The sleeve can be used to match the first thread of the rod body. When the friction of the fork plate at the bottom is insufficient, it can be limited by the connecting rods on both sides to prevent it from rotating. Attached Figure Description

[0025] In this embodiment, after the positioning assembly is installed between the pipe bodies 1 of the two flanges, the positioning holes of the two flanges will be aligned. By rotating the tie rod 5, the two pipe bodies 1 can be temporarily fixed, which makes it convenient for a user to bolt the flanges, thus facilitating fixation. At the same time, the positioning assembly can be removed, so as not to add extra components to the pipe body 1, and also to facilitate the repeated use of the positioning assembly.

[0026] Example 2: Please see Figures 3-4 Based on Embodiment 1, this utility model provides a technical solution: the hook 3 includes a hook body 300, a first connector 301 is fixedly connected to the outer wall of the hook body 300, a second connector 302 is fixedly connected to the outer wall of the hook body 300, the pull rod 5 includes a rod body 500, a threaded head is provided at the bottom of the rod body 500, a locking plate 501 is fixedly connected to the outer wall of the rod body 500, a rotating wheel 502 is fixedly connected to the top outer wall of the rod body 500, and the base 6 includes a sleeve 600, a fork plate 601 is fixedly connected to the bottom outer wall of the sleeve 600, and the bottom of the fork plate 601 is treated with anti-slip treatment.

[0027] In this embodiment, the hook 300 can bridge the connecting rod 2 and the insertion rod 4 via the second connector 302. The first connector 301 can serve as the mounting accessory 7. By rotating the rotating wheel 502, the rod 500 can be raised and lowered on the base 6. In this way, the clamping plate 501 can apply pressure to the insertion rod 4, thereby controlling the two hooks 300 to move closer or further apart. The sleeve 600 can cooperate with the first thread of the rod 500. When the friction of the fork plate 601 at the bottom is insufficient, it can be limited by the connecting rods 2 on both sides, thereby preventing it from rotating.

[0028] Example 3: Please see Figure 5Based on Embodiment 1 and Embodiment 2, this utility model provides a technical solution: an accessory 7 can be added between the two hooks 3.

[0029] In this embodiment, the addition of accessory 7 allows the positioning components to be integrated into a whole, so that the structure can be connected after unloading, making it easy to move. The rod 500 and screw hole 701 prevent the positioning components from shaking after disassembly, making it easy to move the positioning components. The connecting rod 2 avoids the flange hole, which can avoid interfering with the installation bolts.

[0030] The working principle and usage process of this utility model are as follows: After the positioning component is installed between the pipe bodies 1 of the two flanges, the positioning holes of the two flanges will be aligned. By rotating the pull rod 5, the two pipe bodies 1 can be temporarily fixed, which makes it convenient for one user to bolt the flanges, thus facilitating fixation. At the same time, the positioning component can be removed, so as not to add extra components to the pipe body 1, and also to facilitate the repeated use of the positioning component. The hook body 300 can bridge the connecting rod 2 and the insertion rod 4 through the second connector 302. The first connector 301 can serve as the installation part 7. By rotating the rotating wheel 502, the rod body 500 can be positioned at the bottom. The seat 6 is raised and lowered, so that the clamping plate 501 can apply pressure to the insertion rod 4, thereby controlling the two hooks 300 to move closer or further apart. The sleeve 600 can cooperate with the first thread of the rod 500. When the friction of the fork plate 601 at the bottom is insufficient, it can be limited by the connecting rods 2 on both sides to prevent it from rotating. After the addition of accessory 7, the positioning components can be integrated into a whole, so that the structure can be connected after unloading, making it easy to move. The rod 500 and the screw hole 701 can prevent the positioning components from shaking after disassembly, thus facilitating the movement of the positioning components. The connecting rod 2 avoids the flange hole to avoid interfering with the installation bolts.
