Description

Technical Field

[0001] This utility model relates to the field of high-pressure heater processing technology, and in particular to a flipping structure. Background Technology

[0002] The statements herein provide only background information related to this invention and do not necessarily constitute prior art.

[0003] A high-pressure heater is a surface heat exchange device that uses steam extracted from a steam turbine to heat feedwater. Heat transfer is achieved through a piping system consisting of a steam condensation section and a condensate cooling section within the casing. It is primarily used in the regenerative systems of large thermal power units to increase feedwater temperature, thereby enhancing the unit's thermal efficiency and economy. During assembly, the high-pressure heater requires the casing to be flipped into a vertical position before inserting U-shaped or serpentine tubes from top to bottom. Currently, large hoisting equipment is typically used for this assisted flipping, which is cumbersome in terms of operation and site setup, making it impractical. Therefore, a new flipping structure is proposed to address these issues. Utility Model Content

[0004] The purpose of this invention is to address the aforementioned shortcomings by providing a flipping structure that allows for convenient and easy flipping of the shell of a high-pressure heater.

[0005] To solve the above-mentioned technical problems, the present invention adopts the following technical solution: a flipping structure, comprising:

[0006] The base includes a linear module having two moving ends, each of which is provided with a traveling platform, which can drive the two traveling platforms to move closer to or further apart from each other.

[0007] A support assembly is rotatably mounted on two traveling platforms. The support assembly includes a support component and a rotatable and telescopic support platform mounted on its moving end. The two traveling platforms can travel between the horizontally arranged heater housings, and after traveling, the support platform is located outside one end of the heater housing.

[0008] The flipping component, which is mounted on the base, is capable of driving the heater housing to rotate to an upright position after being connected to the heater housing.

[0009] Furthermore, the supporting component includes an assembly platform disposed on the traveling platform, a telescopic rod is disposed laterally on the assembly platform, the moving end of the telescopic rod is connected to the supporting platform, a first motor is disposed on the assembly platform to drive the telescopic rod to rotate, and a clamping component is disposed on the side wall of the supporting platform, the clamping component being able to clamp the heater housing when one end is located inside the supporting platform.

[0010] Furthermore, the support platform includes a hollow platform body with one side open, and the clamping component includes first push rods disposed on both sides of the platform body, with a clamping frame disposed at the moving end of each first push rod.

[0011] Furthermore, a support assembly is provided on the side wall of the platform. The support assembly includes a second push rod provided on the side wall of the heater housing and a support plate provided at the moving end of the second push rod. When the heater housing rotates, it can drive the platform to rotate synchronously. When the heater housing rotates to a vertical position, the second push rod and the support plate are located between the platform and the ground, and at this time, the second push rod can drive the support plate to support the ground.

[0012] Furthermore, the flipping assembly includes a lifting assembly mounted on the base. The moving end of the lifting assembly is provided with a rotating shaft and a second motor. The second motor is capable of driving the rotating shaft to rotate. A pull rope with a hook is wound around the rotating shaft.

[0013] Furthermore, it also includes a support frame, which includes a first frame and a second frame hinged to the base. The second frame is inclined and hinged to the first frame, and is triangularly supported on the ground with the base.

[0014] The beneficial effects of this utility model are reflected in:

[0015] This invention uses a linear module to widen the distance between two traveling platforms, which then propels the device to the heater housing placed on the ground until the support platform is located outside one end of the heater housing. At this point, the two traveling platforms are outside the heater housing. Then, the operator connects the flipping component to the heater housing and drives it to work. The flipping component can drive the heater housing to rotate around the rotational connection between the support component and the support platform until it reaches a vertical position. This device can easily flip the heater housing, thus facilitating subsequent processing. Attached Figure Description

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only a part of the embodiments of the present utility model, and not all of them. Unless otherwise specified, the embodiments and features in the embodiments of this application can be combined with each other. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present utility model.

[0023] Please see Figure 1-4 This utility model discloses a flipping structure, including a base 1 and a heater housing 10. The base 1 includes a linear module 11 and a mounting frame 12. The linear module 11 is mounted on the mounting frame 12, and the bottom of the mounting frame 12 has pulleys that contact the ground. The linear module 11 has two moving ends, and each moving end is equipped with a traveling platform 2. The linear module 11 can drive the two traveling platforms 2 to move closer to each other or further away from each other. The bottom of the traveling platform 2 is also equipped with pulleys, which enable it to move on the ground.

[0024] In one embodiment, the device further includes a support assembly, which is rotatably mounted on two traveling platforms 2. The support assembly includes a support component 3 and a rotatable and retractable support platform 4 mounted at its moving end. The two traveling platforms 2 can travel between the horizontally arranged heater housings 10, and after traveling, the support platform 4 is located outside one end of the heater housing 10. A flipping assembly is provided on the base 1, which can drive the heater housing 10 to rotate to a vertical position after being connected to the heater housing 10.

[0025] In practice, the linear module 11 drives the distance between the two traveling platforms 2 to increase, and then drives the device to the heater housing 10 placed on the ground until the support platform 4 is located outside one end of the heater housing 10. At this time, the two traveling platforms 2 are located outside the heater housing 10. Then, the operator connects the flipping component to the heater housing 10 and drives it to work. The flipping component can drive the heater housing 10 to rotate around the rotational connection between the support component 3 and the support platform 4 until it rotates to a vertical position. This device can easily flip the heater housing 10, which facilitates subsequent processing.

[0026] In addition, since the spacing between the travel platforms 2 can be adjusted, it can accommodate heater housings 10 of different sizes and perform flipping operations, thereby improving its applicability.

[0027] In one embodiment, the supporting component 3 includes an assembly platform 31 mounted on the traveling platform 2. A telescopic rod (not shown) is mounted laterally on the assembly platform 31. The moving end of the telescopic rod is connected to the supporting platform 4. A clamping component is provided on the side wall of the supporting platform 4. The clamping component can clamp the heater housing 10 when one end is inside the supporting platform 4.

[0028] In practice, when the distance between the two traveling platforms 2 is adjusted, the telescopic rod will also extend and retract synchronously, thereby preventing the connection between the bearing component 3 and the bearing platform 4 from being jammed. In addition, the setting of the clamping component makes the heater housing 10 more stable and safe when it is flipped.

[0029] In another embodiment, a first motor 32 that drives the telescopic rod to rotate is installed on the assembly table 31, and the telescopic rod can be a rectangular telescopic rod or a polygonal telescopic rod.

[0030] With this design, the first motor 32 drives the telescopic rod to rotate, and the support platform 4 will rotate together and drive the heater housing 10 to actively flip. At this time, after the flipping component is connected to the end of the heater housing 10 away from the support platform 4, it can save the pressure on the heater housing 10 when flipping, and make the flipping of the heater housing 10 safer and more stable.

[0031] In one embodiment, the support platform 4 includes a hollow platform body 41 with one side open, and the clamping component includes first push rods 42 installed on both sides of the platform body 41. The first push rods 42 may be hydraulic push rods, and each first push rod 42 has a clamping frame 43 installed at its moving end.

[0032] This design allows the corresponding clamping frames 43 to move closer to each other and contact the heater housing 10 by each first push rod 42, thereby enabling very stable clamping and fixing of the heater housing 10.

[0033] In one embodiment, a support assembly is provided on the side wall of the platform 41. The support assembly includes a second push rod 44 mounted on the side wall of the heater housing 10 and a support plate 45 mounted on the moving end of the second push rod 44. The second push rod 44 can be described as a hydraulic push rod.

[0034] In practice, when the heater housing 10 rotates, it can drive the platform 41 to rotate synchronously. When the heater housing 10 rotates to a vertical position, the second push rod 44 and the support plate 45 are located between the platform 41 and the ground. At this time, the second push rod 44 can drive the support plate 45 to support the ground, thereby keeping the heater housing 10, which has been flipped to a vertical position, stable. After the operator separates the flipping component from the heater housing 10, the pipe can be installed inside it.

[0035] In one embodiment, the flipping assembly includes a lifting assembly 5 mounted on the mounting frame 12. The lifting assembly 5 may be a linear drive module. The moving end of the lifting assembly 5 is equipped with a rotating shaft 6 and a second motor 7. The second motor 7 can drive the rotating shaft 6 to rotate. A pull rope 8 with a hook is wound on the rotating shaft 6.

[0036] In practice, the lifting component 5 can drive the rotating shaft 6 to rise and fall until the distance between the rotating shaft 6 and the platform 41 is greater than the length of the heater housing 10. The heater housing 10 has through holes for mounting bolts. By hooking the hook to the through hole and then starting the second motor 7, the pull rope 8 is gradually tightened, thereby driving the heater housing 10 to rotate.

[0037] In one embodiment, the device further includes a support frame 9, which includes a first frame 91 and a second frame 92 hinged to the base 1. The second frame 92 is inclined and hinged to the first frame 91, and is triangularly supported on the ground with the base 1, so that the device has good structural stability when the heater housing 10 is flipped.

[0038] It should be noted that if the embodiments of this utility model involve directional indicators (such as up, down, left, right, front, back, etc.), the directional indicators are only used to explain the relative positional relationship and movement of the components in a certain specific posture (as shown in the figure). If the specific posture changes, the directional indicators will also change accordingly.

[0039] Furthermore, if the embodiments of this utility model involve descriptions such as "first" or "second," these descriptions are for descriptive purposes only and should not be construed as indicating or implying their relative importance or implicitly specifying the number of indicated technical features. Therefore, features defined with "first" or "second" may explicitly or implicitly include at least one of those features.
