Description

Technical Field

[0001] This utility model belongs to the technical field of circulating fluidized bed boilers, specifically a protective device for hanging pipes that is easy to assemble and combine. Background Technology

[0002] Suspension tubes, also known as hanging tubes, are important components in boiler equipment. Their function is to suspend the tubes of convective heating surfaces such as low-temperature reheaters and economizers in the flue at the tail end of the boiler, providing support and suspension to ensure that these heating surface components can be stably installed inside the boiler. They need to suspend the entire tube panel and are load-bearing components that operate in a high-temperature and high-pressure environment.

[0003] Traditional structures used for pipe suspension protection often employ integral metal shells, plates, or segmented welded structures. The former has a large overall size, making it difficult to move and adjust, while the latter requires frequent welding operations, affecting the efficiency of installation and protection, and is inconvenient for subsequent disassembly. Utility Model Content

[0004] To overcome the above-mentioned defects, this utility model provides a protective device for hanging pipes that is easy to assemble and combine. It solves the problems of using an integral metal shell or plate or a segmented welded structure to protect the hanging pipe. The former has a large overall size and is difficult to move and adjust, while the latter requires frequent welding operations, which affects the installation and protection efficiency and is not convenient for subsequent disassembly.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a protective device for hanging pipes that is easy to assemble and splice, comprising a protective shell, a connecting block connected to one side of the protective shell, a connecting groove opened on the other side of the protective shell, an insert plate connected to the protective shell, a slot opened at the end of the protective shell away from the insert plate, a hook plate connected to one side of the upper part of the protective shell, and a fixing rod connected to the other side of the upper part of the protective shell. A return spring is sleeved on the fixed rod, and a sliding sleeve is slidably connected through the fixed rod. A screw is connected to the sliding sleeve, and a threaded cap is threaded to one end of the screw. Slide grooves are opened in the groove walls on both sides of the slot, and connecting springs are connected in the slide grooves. A locking block is connected to one end of the connecting spring.

[0006] As a further embodiment of this utility model: both the insert plate and the slot are arc-shaped, and the insert plate and the slot are interlocked; the connecting block is T-shaped and slides with the connecting groove.

[0007] As a further embodiment of this utility model: one end of the return spring is connected to the protective shell wall, the other end of the return spring is connected to the sliding sleeve, and the screw is attached to the hook groove of the hook plate.

[0008] As a further embodiment of this utility model: the card block slides in the groove and contacts the groove wall, the end of the card block away from the connecting spring is designed with a hemispherical arc surface, and the insert plate has card slots on both sides, and the card block is fitted into the card slots.

[0009] As a further embodiment of this utility model: the protective shell is U-shaped, and an anti-slip pad is connected to the inner side of the protective shell, the anti-slip pad being made of rubber.

[0010] As a further embodiment of this utility model: a groove is provided on one side of the hook plate, the threaded cap is embedded in the groove, and the threaded cap is provided with anti-slip texture.

[0011] Compared with the prior art, the beneficial effects of this utility model are as follows: 1. This easy-to-assemble protective device for hanging pipes, through the setting of connecting blocks, connecting grooves, insert plates, slots, connecting springs, and locking blocks and slots, allows workers to insert the insert plate into the slot. During this process, the insert plate pushes the arc surface of the locking block, causing the locking block to slide into the groove and compress the connecting spring. Then, the rebound of the connecting spring pushes the locking block, causing the locking block to lock into the slot, thereby combining and fixing multiple protective shells. This allows multiple protective blocks to provide comprehensive and stable protection for the hanging pipes, effectively preventing dust and impurities in the high-temperature flue gas in the boiler tail flue from directly adhering to the surface of the hanging pipes. Furthermore, by pushing the connecting block into the connecting groove, the flat sides of the two sides of the U-shaped protective shell are pressed tightly against each other, ensuring that multiple hanging pipes are arranged at equal intervals to form a pipe screen and to form a continuous and sealed protective bonding surface, reducing gaps. The modular design makes it easy for workers to handle and install, and the operation is simple, requiring no welding fixation, thus improving efficiency. 2. This easy-to-assemble protective device for hanging pipes consists of a sliding sleeve, a return spring, a screw, a hook plate, a threaded cap, and a groove. By rotating the screw downwards and pushing it, the sliding sleeve slides on the fixed rod and compresses the return spring. Then, the return spring's rebound allows one end of the screw to engage in the hook groove of the hook plate. During this process, the downward-rotating screw presses down on the hanging pipe, causing it to squeeze the anti-slip pad. This increases friction between the anti-slip pad and the hanging pipe, preventing slippage. The hook plate's obstruction keeps the return spring compressed. Finally, the threaded cap is screwed in, causing it to embed into the groove and press against the groove wall, thus completing the fixation. Attached Figure Description

[0013] The technical solution of this patent will be further described in detail below with reference to specific embodiments.

[0014] like Figure 1-4 As shown, this utility model provides a technical solution: a protective device for hanging pipes that is easy to assemble and combine, including a protective shell 1, a connecting block 2 connected to one side of the protective shell 1, a connecting groove 3 opened on the other side of the protective shell 1, an insert plate 4 connected to the protective shell 1, and a slot 5 opened at the end of the protective shell 1 away from the insert plate 4. Both the insert plate 4 and the slot 5 are arc-shaped and are interlocked with each other. The connecting block 2 is T-shaped and slides with the connecting groove 3. By pushing the connecting block 2 into the connecting groove 3, multiple protective shells 1 can be combined laterally. The T-shaped structure of the connecting block 2 can limit the movement and prevent multiple protective shells 1 from accidentally sliding off.

[0015] A hook plate 6 is connected to one side of the upper part of the protective shell 1. A groove 17 is opened on one side of the hook plate 6. The threaded cap 11 is embedded in the groove 17 and the threaded cap 11 is provided with anti-slip texture. The anti-slip texture makes it easy for the staff to turn the threaded cap 11, which facilitates fixing and loosening. The engagement of the threaded cap 11 with the groove 17 can prevent the threaded cap 11 from sliding accidentally.

[0016] A fixing rod 7 is connected to the other side of the upper part of the protective shell 1. The protective shell 1 has an overall U-shaped design, and an anti-slip pad 16 is connected to the inner side of the protective shell 1. The anti-slip pad 16 is made of rubber. By squeezing the hanging tube with the lower screw 10, the anti-slip pad 16 is tightly attached to the surface of the hanging tube, thereby preventing the protective shell 1 from sliding along the axial direction of the hanging tube.

[0017] A return spring 8 is sleeved on the fixed rod 7, and a sliding sleeve 9 is slidably connected through the fixed rod 7. A screw 10 is connected to the sliding sleeve 9. One end of the return spring 8 is connected to the wall of the protective shell 1, and the other end of the return spring 8 is connected to the sliding sleeve 9. The screw 10 overlaps with the hook groove of the hook plate 6. Through the elastic force of the return spring 8, the sliding sleeve 9 can be pushed to drive the screw 10 to always apply pressure in the direction of the hook plate 6, ensuring that the screw 10 and the hook groove overlap tightly.

[0018] One end of the screw 10 is threaded with a threaded cap 11. The slot 5 has a sliding groove 12 on both sides of the groove wall. A connecting spring 13 is connected in the sliding groove 12. One end of the connecting spring 13 is connected with a locking block 14. The locking block 14 slides in the sliding groove 12 and contacts the groove wall of the sliding groove 12. The end of the locking block 14 away from the connecting spring 13 has a hemispherical arc surface design. The insert plate 4 has a slot 15 on both sides. The locking block 14 fits into the slot 15. The spherical arc surface of the locking block 14 makes it easy to push the insert plate 4, which makes it easy for the staff to insert and pull out the insert plate 4, complete the installation and disassembly, and improve efficiency.

[0019] The working principle of this utility model is as follows: Multiple protective shells 1 are pushed onto the hanging pipe, causing the insert plate 4 to be inserted into the slot 5. During this process, the insert plate 4 pushes the locking block 14, causing the locking block 14 to slide into the slide groove 12 and compress the connecting spring 13. Then, the rebound of the connecting spring 13 pushes the locking block 14, causing the locking block 14 to lock into the slot 15, thereby combining and fixing the multiple protective shells 1 together. This allows the multiple protective blocks to provide comprehensive and stable protection for the hanging pipe. Afterwards, by rotating downwards and pushing the screw 10, the sliding sleeve 9 slides on the fixed rod 7 and compresses the return spring 8. Then, the return spring... The rebound of screw 10 allows one end of screw 10 to be engaged in the hook groove of hook plate 6. During the process, the downward rotation of screw 10 will press down on the hanging tube, causing the hanging tube to squeeze the anti-slip pad 16, so that the anti-slip pad 16 and the hanging tube are in close contact to increase friction, thereby preventing slippage. Then, screw on the threaded cap 11 to make the threaded cap 11 embed into the groove 17 and press against the groove wall to complete the fixation. Finally, push the connecting block 2 into the connecting groove 3 to make the two flat sides of the U-shaped protective shell 1 stick to each other, ensuring that multiple hanging tubes are arranged at equal intervals to form a tube screen and form a continuous and sealed protective bonding surface.
