Description

Technical Field

[0001] This invention relates to the field of steam pipeline installation technology, and in particular to a heat recovery steam pipeline hoisting frame. Background Technology

[0002] Steam pipes are very common in steam turbine units. Pipe supports and hangers used to install and fix steam pipes are used wherever pipes are laid. As a supporting structure for pipes, the function of pipe supports and hangers is to fix the pipes and bear the weight of the pipes themselves and the fluid inside.

[0003] Because the steam flowing inside the steam pipes is at a high temperature, the clamps of the steam pipe hoisting frame may undergo plastic deformation due to the high temperature. In severe cases, this can cause the pipe at the location of the clamps on the hoisting frame to sink, potentially leading to breakage at the connection between the hoisting frame and the steam pipe. Damage to the pipe structure can seriously compromise the safe operation of the unit. Therefore, it is crucial to reinforce the steam pipe hoisting frame and ensure proper heat dissipation at the clamps. Summary of the Invention

Therefore, the invention is not limited to the specific embodiments disclosed below.

[0028] Secondly, the term "one embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in different places in this specification does not necessarily refer to the same embodiment, nor is it a single or selective embodiment that is mutually exclusive with other embodiments.

[0029] Secondly, the present invention is described in detail with reference to the schematic diagrams. When detailing the embodiments of the present invention, for ease of explanation, the cross-sectional views illustrating the device structure may be partially enlarged, not according to the usual scale. Furthermore, the schematic diagrams are merely examples and should not limit the scope of protection of the present invention. In addition, actual fabrication should include three-dimensional spatial dimensions of length, width, and depth.

[0030] Example 1, referring to Figure 1 The first embodiment of the present invention provides a heat recovery steam pipeline hoisting frame. This device includes a hoisting frame unit 100, a clamping plate connecting unit 200, and a heat transfer unit 300.

[0031] The hoisting frame unit 100 includes a pipe hoisting frame 101, a clamping plate 102 mounted on the pipe hoisting frame 101, and a clamping plate fixing member 103 mounted on the clamping plate 102. The hoisting frame unit 100 is used for installing steam pipes on a steam turbine unit. The clamping plate connecting unit 200 includes a clamping plate connecting cover 201 mounted on the clamping plate 102, a connecting cover mounting plate 203 mounted on the clamping plate connecting cover 201, and a mounting plate fixing member 202 mounted on the connecting cover mounting plate 203. The clamping plate connecting unit 200 is used to connect the heat transfer unit 300 to the hoisting frame unit 100, and simultaneously connect the clamping plate 102 to the heat recovery pipe 302, improving the stability of the clamping plate 102. The heat transfer unit 300 includes a heat recovery pipe 302 disposed on the clamping plate connecting unit 200, and a heat transfer component 301 disposed on the heat recovery pipe 302, one end of which is connected to the clamping plate 102 and the other end of which is located inside the heat recovery pipe 302. The heat transfer unit 300 concentrates and recovers heat from the clamping plate 102 into the heat recovery pipe 302, thereby recovering residual heat from the clamping plate 102 and simultaneously dissipating heat from the clamping plate 102. This reduces the probability that plastic deformation of the clamping plate 102 due to high temperature will affect the safe operation of the steam pipeline.

[0032] During use, the pipe hoisting frame 101 is placed on the surface of the steam pipe to be fixed, and the clamps 102 on the pipe hoisting frame 101 are connected to each other using the clamp fixing parts 103. A heat recovery pipe 302 is placed on one side of the steam pipe. The heat recovery pipe 302 concentrates and recovers the residual heat of the steam pipe to the area requiring high-temperature heating, thereby achieving the reuse of heat energy. By setting up the heat transfer unit 300, the heat transfer part 301 achieves concentrated recovery of heat from the clamps 102 on the hoisting unit 100, where heat is most easily concentrated. The heat on the clamps 102 is concentrated and recovered into the heat recovery pipe 302, realizing the recovery of residual heat on the clamps 102 and simultaneously serving a heat dissipation function for the clamps 102, thereby reducing the probability that the clamps 102 will undergo plastic deformation due to high temperature, affecting the safe operation of the steam pipe.

[0033] Furthermore, the pipe hoisting frame 101 includes an upper hoisting frame 101a disposed above the steam pipe and a lower hoisting frame 101b disposed below the steam pipe; the clamping plate 102 includes an upper clamping plate 102a disposed on the upper hoisting frame 101a and a lower clamping plate 102b disposed on the lower hoisting frame 101b.

[0034] Furthermore, the clamping plate connecting cover 201 includes a heat transfer tube mounting bracket 201a and a heat transfer tube mounting bracket 201c disposed on the pipe hoisting frame 101, and a connecting frame 201b disposed between the heat transfer tube mounting bracket 201a and the heat transfer tube mounting bracket 201c; the heat transfer tube mounting bracket 201a and the heat transfer tube mounting bracket 201c are provided with heat transfer tube mounting grooves 201c-1; the connecting cover mounting plate 203 includes an upper mounting plate 203a and a lower mounting plate 203b disposed on the connecting frame 201b.

[0035] During use, the upper lifting frame 101a and the lower lifting frame 101b are respectively set on the upper and lower sides of the steam pipe to be fixed. Then, the upper clamping plate 102a and the lower clamping plate 102b are fixedly connected using the clamping plate fixing member 103, thereby setting the pipe lifting frame 101 on the steam pipe. A clamping plate connecting cover 201 is set to connect the clamping plate connecting unit 200 and the lifting frame unit 100. An upper mounting plate 203a and a lower mounting plate 203b are set on the connecting frame 201b to facilitate the installation and connection of the clamping plate connecting cover 201 with the clamping plate 102 of the lifting frame for steam pipes of different sizes, thereby providing heat dissipation and reinforcement for the clamping plate 102 of different sizes.

[0036] Example 2, refer to Figure 1-4 This is the second embodiment of the present invention. The difference between this embodiment and the first embodiment is that the heat transfer component 301 includes a heat transfer part 301a disposed on the heat recovery pipe 302, one end of which is connected to the clamping plate 102 and the other end of which is located in the heat recovery pipe 302, and a heat conduction plate 301b disposed on the heat transfer part 301a.

[0037] During use, the pipe hoisting frame 101 is placed on the surface of the steam pipe to be fixed, and the clamps 102 on the pipe hoisting frame 101 are connected to each other using the clamp fixing parts 103. A heat recovery pipe 302 is placed on one side of the steam pipe. The heat recovery pipe 302 concentrates and recovers the residual heat of the steam pipe to the area requiring high-temperature heating, thereby achieving the reuse of heat energy. By setting up a heat transfer unit 300, the heat transfer part 301 achieves concentrated recovery of heat from the clamps 102 on the hoisting unit 100, where heat is most easily concentrated. The heat on the clamps 102 reaches the heat-conducting plate 301b, which slides on the heat transfer part 301a, thereby concentrating and recovering the heat on the clamps 102 into the heat recovery pipe 302. This achieves the recovery of residual heat on the clamps 102 and also dissipates heat from the clamps 102, thereby reducing the probability that the clamps 102 will undergo plastic deformation due to high temperature, affecting the safe operation of the steam pipe.

[0038] Compared to Embodiment 1, the heat transfer assembly 301 further includes a sliding portion 301d with a heat-conducting plate 301b; the sliding portion 301d includes a guide rod 301d-2 disposed on the heat transfer portion 301a, a sliding seat 301d-1 slidably disposed on the guide rod 301d-2 and connected to the heat-conducting plate 301b, and a spring 301d-3 sleeved on the guide rod 301d-2.

[0039] During use, by setting the guide rod 301d-2, the heat-conducting plate 301b connected to the sliding seat 301d-1 is guided to slide on the heat transfer section 301a. This allows the heat-conducting plate 301b to reciprocate on the heat transfer section 301a with the airflow between the clamping plate 102 and the heat recovery pipe 302, thereby accelerating the gas flow on the heat transfer component 301 and improving the heat dissipation efficiency on the clamping plate 102. This is beneficial to increasing the total amount of heat collected in the heat recovery pipe 302.

[0040] Preferably, the heat transfer assembly 301 further includes blades 301c disposed on one end of the heat-conducting plate 301b near the clamping plate 102. By disposing of the blades 301c, the airflow can drive the blades 301c to rotate on the side of the heat-conducting plate 301b near the clamping plate 102, thereby improving the sliding driving effect of the heat-conducting plate 301b on the heat transfer section 301a, and further improving the heat dissipation and transfer rate at the clamping plate 102.

[0041] Furthermore, the heat transfer unit 300 also includes a rotating assembly 303. The rotating assembly 303 includes a first rotating seat 303a and a second rotating seat 303c rotatably mounted on the clamping plate connecting cover 201, and a heat transfer component rotating frame 303b disposed between the first rotating seat 303a and the second rotating seat 303c, on which the heat transfer component 301 is mounted. By setting the rotating assembly 303, the first rotating seat 303a and the second rotating seat 303c drive the heat transfer rotating frame 303b and the heat transfer component 301 thereon to reciprocate within the space between the clamping plate 102 and the heat recovery pipe 302, thereby further improving the gas flow inside the clamping plate 102 and the heat recovery pipe 302, which is beneficial to improving the heat recovery and heat dissipation on the clamping plate 102.

[0042] The remaining structure is the same as that in Example 1.

[0043] Example 3, referring to Figure 1-6 This is the third embodiment of the present invention. The difference between this embodiment and the second embodiment is that the heat transfer component 301 further includes a fan blade heat conduction part 301e. The fan blade heat conduction part 301e includes a heat conduction groove 301e-1 disposed on the heat conduction plate 301b, and a heat conduction fan blade 301e-3 rotatably disposed on the heat conduction groove 301e-1.

[0044] During use, the pipe hoisting frame 101 is placed on the surface of the steam pipe to be fixed, and the clamps 102 on the pipe hoisting frame 101 are connected to each other using the clamp fixing parts 103. A heat recovery pipe 302 is placed on one side of the steam pipe, concentrating and recovering the residual heat from the steam pipe to the area requiring high-temperature heating, thus achieving the reuse of heat energy. By setting up a heat transfer unit 300, the heat transfer part 301 achieves concentrated recovery of heat from the clamps 102 on the hoisting unit 100, where heat is most easily concentrated. The heat on the clamps 102 reaches the heat-conducting plate 301b, which slides on the heat transfer part 301a, thereby concentrating and recovering the heat on the clamps 102 into the heat recovery pipe 302, achieving the recovery of residual heat on the clamps 102. By setting up a fan blade heat-conducting part 301e, the heat-conducting fan blades 301e-3 further improve the heat conduction efficiency of the heat transfer assembly 301. At the same time, it also serves to dissipate heat from the clamping plate 102, thereby reducing the probability that the clamping plate 102 will undergo plastic deformation due to high temperature, which may affect the safe operation of the steam pipeline.

[0045] Compared to Embodiment 2, the heat-conducting part 301e of the fan blade further includes a guide block 301e-4 disposed on the heat recovery pipe 302. The side of the guide block 301e-4 near the fluid inlet end of the heat recovery pipe 302 is configured as a front guide slope 301e-41, and the side of the guide block 301e-4 near the fluid outlet end of the heat recovery pipe 302 is configured as a rear guide slope 301e-42. By setting the guide block 301e-4, when the heat recovery pipe 302 is connected to a pipe containing the fluid to be heated, the fluid first reaches the fluid inlet end of the heat recovery pipe 302, and enters one side of the drive shaft of the heat-conducting fan blade 301e-3 under the guidance of the front guide slope 301e-41, thereby causing the heat-conducting fan blade 301e-3 to rotate on the heat-conducting groove 301e-1, thereby realizing the transfer and dissipation of heat on the clamping plate 102. It is important to note that when performing heat recovery, the sealing of the heat recovery pipe 302 must be ensured to be consistent with the operation of the fluid flowing inside the heat recovery pipe 302, so as to prevent leakage from the heat recovery pipe 302.

[0046] Preferably, the fan blade heat-conducting part 301e further includes a heat-conducting strip 301e-2 disposed on the heat-conducting groove 301e-1.

[0047] During use, the heat-conducting strip 301e-2 is made of a material that can collect heat in a concentrated manner, thereby absorbing the heat generated by the clamping plate 102 onto the heat-conducting groove 301e-1, and then allowing the heat to enter the heat recovery pipe 302 along the heat-conducting groove 301e-1 and the heat-conducting fan blade 301e-3 on the heat-conducting groove 301e-1, thus realizing the heat recovery at the clamping plate 102.

[0048] The remaining structure is the same as that in Example 2.
