Description

Technical Field

[0001] The invention relates to the technical field of heating systems, in particular to a hoisting structure for disassembling pipeline accessories. Background Art

[0002] The boiler room and heat exchange station of a heating system are the heart of the system. Due to environmental, site, and equipment limitations, the piping within the station is crisscrossed, with the main pipeline often located on the roof, 3 to 6 meters above the ground. Furthermore, various functional accessories such as valves and flow meters (hereinafter referred to as "pipeline accessories") are also installed on the roof due to their inherent installation process requirements. When these piping accessories need to be inspected or replaced on the ground, disassembly and installation becomes a complex issue.

[0003] The current practice is to first build a scaffold or mobile scaffolding, then construct a walkway from the scaffolding, with operators performing disassembly and installation on the walkway. This method has the disadvantage that the flanges on the pipelines hold the pipe accessories very tightly when the system is in operation, typically withstanding a pressure of 0.1 to 1.5 MPa. During disassembly, a 1 to 2 mm gap must be maintained between each pair of connecting flanges at both ends of the pipe accessory. Only when this adjustment is met can the pipe accessory be removed. When installing the pipe accessory, it must be lifted into place before the connecting bolts are inserted. This requires the pipe accessory to remain secure for a long time, but the weight of the replaced pipe accessory can range from tens of kilograms to 100 to 200 kilograms, making it very difficult to maintain the stability of the pipe accessory for a long time.

Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0031] Reference Figures 1-4As shown, a lifting structure for disassembling pipe accessories includes a main pipe 100, a first clamp 200, a support seat 400 and a force frame 700. The two ends of the main pipe 100 are fixedly connected to the pipe accessories 101 through flanges. There are two first clamps 200 and they are respectively arranged on the surfaces of the two pipe accessories 101. The bottom end of the first clamp 200 is provided with a second clamp 201. The first clamp 200 and the second clamp 201 form a circular ring shape. Both ends of the first clamp 200 and the second clamp 201 are fixedly connected with fastening ears and are fixedly connected by fastening bolts 202. The support seat 400 is fixedly connected to the top of the first clamp 200. The top of the support seat 400 is fixed It is fixedly connected with a support rod 401, and the top end of the support rod 401 is fixedly connected with a socket block 402, and a connecting rod 500 is slidably inserted inside the socket block 402. There are two connecting rods 500, and the two connecting rods 500 are fixedly connected through an adjusting rod 501. The surface of the adjusting rod 501 is socketed with a hanging ear 502, and the bottom end of the hanging ear 502 is fixedly connected with a lifting head 600. A rope 601 is provided inside the lifting head 600, and the end of the rope 601 is fixedly connected with a hook 602. The surface of the main pipe 100 is socketed with a lifting rope 603, and the lifting rope 603 is socketed on the surface of the hook 602. There are two force frames 700, and the divided surfaces are located on both sides of the main pipe 100. The pipe accessory 101 fixedly connected at both ends of the main pipe 100 cooperates with the first clamp 200 and the second clamp 201 to achieve stable clamping of the pipe accessory 101; the support seat 400, the support rod 401 and the socket block 402 constitute an adjustable lifting support frame, and the sliding plug-in design of the connecting rod 500 and the adjusting rod 501 facilitates adjustment of the lifting position; the lifting head 600 cooperates with the rope 601, the hook 602 and the lifting rope 603 to realize the lifting of the main pipe 100; the force frame 700 provides an external force interface to facilitate the disassembly of the flange connection of the pipe accessory 101. The overall structure takes into account both clamping stability and lifting flexibility, effectively improving the efficiency and safety of the disassembly operation of the pipe accessory 101.

[0032] Further preferably, a threaded bolt 403 is threadedly connected to the side of the socket block 402, and the end of the threaded bolt 403 passes through the side wall of the socket block 402 and abuts the surface of the connecting rod 500. The end of the threaded bolt 403 passes through the side wall of the socket block 402 and abuts the surface of the connecting rod 500. After adjusting the insertion depth of the connecting rod 500, its position can be locked, preventing the connecting rod 500 from accidentally sliding during the hoisting process, and ensuring the stability of the hoisting height and position.

[0033] Further preferably, the hoisting head 600 has a diamond-shaped structure, comprising two diamond-shaped plates, a connecting shaft, and a pulley. The connecting shaft is disposed between the two diamond-shaped plates, and the pulley runs through the connecting shaft and is disposed between the two diamond-shaped plates. The rope 601 is wound around the surface of the pulley. The diamond-shaped hoisting head 600 utilizes the mechanical properties of the diamond-shaped plates to disperse the hoisting force, thereby improving the structure's resistance to deformation. The pulley can change the direction of force applied to the rope 601, reducing friction loss between the rope 601 and the hoisting head 600 during the hoisting process, extending the service life of the rope 601, and facilitating adjustment of the hoisting angle of the hook 602.

[0034] Further preferably, hinge blocks 203 are fixedly connected to both sides of the bottom end of the second clamp 201. A support tube 300 is rotatably connected to the hinge block 203. A threaded support tube 301 is threadedly inserted into the bottom end of the support tube 300. The bottom end of the threaded support tube 301 is rotatably connected to a swivel 302. The bottom end of the swivel 302 is rotatably connected to a ground support 303. The surface of the ground support 303 is plugged with a ground stake 304. The rotatable connection between the hinge block 203 and the support tube 300 allows the support structure to adapt to different ground inclination angles. The threaded fit between the threaded support tube 301 and the swivel 302 facilitates adjustment of the overall height of the support tube 300. The plug-in fixation of the ground support 303 and the ground stake 304 firmly supports the entire hoisting structure on the ground, effectively preventing the structure from tipping over due to a shift in the center of gravity during hoisting, and improving operational safety.

[0035] Further preferably, both ends of the force-applying frame 700 are fixedly connected to sleeve blocks 701, a force-applying rod 702 is slidably inserted into the sleeve blocks 701, and a connector 703 is fixedly connected to the end of the force-applying rod 702. The connector 703 is located between the fastening ear at one end of the first clamp 200 and the fastening ear at one end of the second clamp 201. The surface of the connector 703 is provided with a slot for the fastening bolt 1 202 to pass through. The sliding plug-in design of the sleeve block 701 and the force-applying rod 702 allows the force-applying position to be adjusted along the axial direction of the main pipe 100. After the connector 703 is inserted into the slot between the fastening ears, the force-applying rod 702 can be pushed by external force to loosen the fastening bolt 1 202, thereby facilitating the removal of the connection between the pipe accessory 101 and the first clamp 200. This is convenient and does not damage the original clamping structure.

[0036] Further preferably, a second fastening bolt 704 is threadedly connected to the side of the sleeve block 701, and the end of the second fastening bolt 704 is tightly fitted with the surface of the force-applying rod 702. The second fastening bolt 704 can lock the force-applying rod 702 after it is adjusted to the target position, preventing the force-applying rod 702 from accidentally retracting or sliding during the force application process, thereby ensuring a stable and controllable force application process during the disassembly operation.

[0037] Further preferably, two movable blocks 800 are provided on one side of the force application frame 700. The top of the movable block 800 is slidably coupled to the top frame of the force application frame 700, and the bottom of the movable block 800 is slidably coupled to the bottom frame of the force application frame 700. The top and bottom ends of the movable block 800 are fixedly connected to a fixed block 801. An insert rod 803 is slidably coupled to the interior of the fixed block 801, and one end of the insert rod 803 is fixedly connected to a limit guide bar 804. The sliding movement of the movable block 800 along the top and bottom frames of the force application frame 700 can adjust the horizontal position of the limit guide bar 804 so that it is in contact with the outer wall of the main pipe 100. The sliding movement of the insert rod 803 within the fixed block 801 can fine-tune the vertical pressure of the limit guide bar 804, thereby firmly attaching the force application frame 700 to the surface of the main pipe 100 and preventing the force application frame 700 from shifting during installation or removal.

[0038] Further preferably, a third fastening bolt 802 is threadedly inserted into the side of the fixing block 801. The end of the third fastening bolt 802 abuts the surface of the insertion rod 803, and the limiting guide strip 804 is tangent to the main pipe 100. The third fastening bolt 802 can lock the sliding position of the insertion rod 803, so that the limiting guide strip 804 and the main pipe 100 maintain a stable fit. The design of the limiting guide strip 804 being tangent to the main pipe 100 can increase contact friction, further improving the stability of the connection between the force application frame 700 and the main pipe 100, and preventing structural deviation during operation.

[0039] Working principle: First, the two first clamps 200 are respectively placed on the surface of the pipe accessories 101 at both ends of the main pipe 100, and then the second clamp 201 is fixedly connected to the first clamp 200 through the fastening ear and the fastening bolt 202, so that the first clamp 200 and the second clamp 201 form a circular clamping structure, which fits the pipe accessory 101 tightly from both sides to complete the preliminary fixation of the pipe accessory 101 and prevent it from accidentally falling off during the disassembly process. The support seat 400 is fixed to the top of the first clamp 200 and connected to the socket block 402 through the support rod 401; the two connecting rods 500 are slidably inserted into the socket block 402 and connected through the adjustment rod 501. The insertion depth of the connecting rod 500 can be adjusted according to the height of the main pipeline 100 or the lifting requirements, and then the position of the connecting rod 500 is locked by the threaded bolt 403 to ensure the vertical support stability of the lifting structure. The lifting head 600 adopts a diamond structure, and the pulley inside it cooperates with the rope 601 to transfer the weight of the main pipeline 100 to the rope 601 through the hook 602, and then the rope 603 is dispersed to the surface of the main pipeline 100. The mechanical properties of the diamond structure are used to disperse the force. At the same time, the pulley reduces the friction loss between the rope 601 and the lifting head 600 to ensure the stability of the lifting process. The hinge block 203 at the bottom of the second hoop 201 rotates with the support tube 300 The connection can adjust the direction of the support tube 300 according to the inclination angle of the ground; the threaded support tube 301 and the rotating head 302 are threaded together to adjust the support height, and finally the entire structure is firmly fixed to the ground through the ground pile 304 on the surface of the ground support 303 to prevent the structure from tipping over due to the center of gravity shift during the lifting process. The force frame 700 is slidably connected to the force rod 702 through the sleeve block 701, and the force position is adjusted along the axial direction of the main pipe 100; the connector 703 at the end of the force rod 702 is inserted into the slot position between the fastening ears of the first clamp 200 and the second clamp 201, and the force rod 702 is pushed by external force to loosen the fastening bolt 202; after the adjustment is completed, it is tightened by tightening The second bolt 704 locks the force rod 702 to ensure the stable application of the disassembly force, and finally completes the flange connection and disassembly of the pipe accessory 101 and the first clamp 200. The movable block 800 on one side of the force frame 700 can slide along the top frame and the bottom frame, driving the limiting guide bar 804 to fit the outer wall of the main pipe 100; the insertion rod 803 slides in the fixed block 801 to fine-tune the guide bar pressure, and the position of the insertion rod 803 is locked by tightening the third bolt 802, so that the force frame 700 is tightly fitted with the main pipe 100, and the tangential contact between the limiting guide bar 804 and the main pipe 100 is used to increase the friction force, prevent the force frame 700 from shifting during the operation, and ensure the safety of the disassembly operation.
