Description

Technical Field

[0001] This invention relates to the field of steel structure construction technology, and in particular to a steel structure hoisting structure and method for reheat boilers. Background Technology

[0002] Essentially, a reheater is a steam superheater that reheats low-pressure steam that has already done work to a certain temperature. The reheater further improves the thermal efficiency of the power plant cycle and keeps the steam temperature of the turbine's last-stage blades within an acceptable range. The reheater is the heater in the boiler that heats the steam coming out of the turbine into superheated steam. The reheater has two functions: first, it reduces the humidity of the steam, which helps protect the turbine blades; second, it can improve the turbine's relative and absolute internal efficiency. When installing the steel structure of the reheat boiler, a hoisting device is needed to lift the boiler's steel structure to the required location for installation.

[0003] Existing hoisting equipment typically requires steel structure lifting devices to secure the steel structure during hoisting to prevent it from falling off. However, reheat boiler steel structures vary in size and weight. During hoisting, some overweight steel structures are prone to falling off due to instability, which can damage the steel structure and cause safety accidents. Summary of the Invention

[0004] The purpose of this invention is to address the shortcomings of existing technologies, such as the tendency for some overweight steel structures to fall off during hoisting due to instability of the center of gravity, which not only damages the steel structure but also causes safety accidents. Therefore, this invention proposes a hoisting structure and method for reheat boiler steel structures.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] Design a steel structure hoisting structure for a reheat boiler, including a connecting plate connected to a hoisting rope of a hoisting device, the connecting plate having through holes that cooperate with the hoisting rope, and two buckle assemblies on the connecting plate, the buckle assemblies being connected to the hoisting rope for hoisting the steel structure;

[0007] The buckle assembly includes a first mounting part and a lifting ring for connecting the lifting rope. The lifting ring is connected to the first mounting part. The buckle assembly is slidably connected to the connecting plate, and a limit mechanism is provided between the buckle assembly and the connecting plate.

[0008] Furthermore, the connecting plate is provided with a guide groove that cooperates with the buckle assembly, and the buckle assembly also includes a guide block that cooperates with the guide groove.

[0009] Furthermore, the guide block is fixedly connected to the first mounting part, and a second mounting part is provided at the other end of the guide block, which is detachably connected to the guide block.

[0010] Furthermore, the guide block has a slot, and the second mounting part is fixedly provided with two plugs that cooperate with the slot. An elastic element is provided between the two plugs, and the slot is provided with a groove that cooperates with the elastic element.

[0011] Furthermore, the elastic element includes two elastic arms, which are fixedly connected to form a V-shaped structure and the upper end of the V-shaped structure is fixedly connected to the second mounting part. Each elastic arm is fixedly provided with a buckle part that cooperates with the slot.

[0012] Furthermore, two abutting parts are slidably disposed within the second mounting part, and a button is also slidably disposed within the second mounting part. The button is fixedly connected to the two abutting parts, and the other end of the button passes through the second mounting part and extends to its outside.

[0013] Furthermore, the limiting mechanism includes multiple mounting holes formed on the connecting plate, and a pin corresponding to the mounting hole is movably inserted into the first mounting part.

[0014] Furthermore, a spring is provided between the pin and the first mounting part, and a dustproof plate that cooperates with the first mounting part is fixedly provided on the pin. The other end of the dustproof plate is connected to an auxiliary component that is convenient for workers to hold.

[0015] Furthermore, limit grooves are provided on both sides of the connecting plate, and limit blocks that cooperate with the limit grooves are fixedly provided on both the first mounting part and the second mounting part.

[0016] A method for hoisting a reheat boiler steel structure, including the aforementioned reheat boiler steel structure hoisting structure, further includes the following steps.

[0017] S1. Connect the through hole of the hoisting structure connecting plate to the hoisting rope of the hoisting device;

[0018] S2. By moving the external auxiliary component, the pin is separated from the mounting hole, the buckle assembly is moved, and the positions of the two buckle assemblies are adjusted.

[0019] S3. Connect the hoisting ropes using the buckle assembly, and then use the hoisting ropes to secure the steel structure for hoisting.

[0020] S4. When the steel structure is large in volume and heavy in weight, adjust the position of the two buckle components to reduce the distance, so that the two lifting ropes are tied to the same steel structure, thus avoiding individual steel structures being overweight and affecting the hoisting.

[0021] The present invention provides a steel structure hoisting structure and method for reheat boilers, which has the following advantages:

[0022] In this invention, when lifting a lighter steel structure, the two buckle components can be used to lift the steel structure simultaneously, thereby improving the lifting efficiency. When lifting an overweight steel structure, the lifting ropes on the two buckle components can be tied to the overweight steel structure to share the weight and prevent damage caused by excessive force on a single buckle component.

[0023] Secondly, in this invention, the positions of the two buckle components can be adjusted according to the center position of the steel structure, thereby ensuring that the center of the steel structure is between the lifting ropes of the two buckle components, and ensuring that the steel structure will not fall off during hoisting.

[0030] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0031] Reference Figure 1-5 A reheat boiler steel structure hoisting structure includes a connecting plate 1 connected to the hoisting rope of the hoisting device, a through hole 2 on the connecting plate 1 that cooperates with the hoisting rope, and two buckle assemblies 3 on the connecting plate 1. The buckle assemblies 3 are connected to the hoisting rope for hoisting the steel structure.

[0032] The buckle assembly 3 includes a first mounting part 31 and a lifting ring 32 for connecting the lifting rope. The lifting ring 32 is connected to the first mounting part 31. The buckle assembly 3 is slidably connected to the connecting plate 1, and a limit mechanism 4 is provided between the buckle assembly 3 and the connecting plate 1.

[0033] In this invention, when lifting lighter steel structures using two locking components 3, the steel structures can be lifted simultaneously by the two locking components 3. During lifting, the lifting ropes simultaneously suspend two steel beams, and they are tied and lifted according to the principle of lower positioning elevation (i.e., the steel beam with the highest elevation is lifted to the top layer of the same hoist, and so on, with the lowest elevation lifted to the bottom layer). At the same time, the principle of lifting longer steel beams to the bottom and shorter steel beams to the top is taken into account, which is beneficial for the positioning of steel beams, reduces the labor intensity of construction workers, improves work efficiency, shortens the construction period, and thus achieves the effect of reducing costs. When lifting heavy steel structures, the lifting ropes on the two locking components 3 are tied to the heavy steel structure to distribute the weight and prevent damage caused by excessive force on a single locking component.

[0034] Furthermore, in this embodiment, the connecting plate 1 is provided with a guide groove 5 that cooperates with the buckle assembly 3. The buckle assembly 3 also includes a guide block 33 that cooperates with the guide groove 5. By setting the guide block 33 to cooperate with the guide groove 5, the force received by the buckle assembly 3 is transmitted to the connecting plate 1, and then to the hoisting device.

[0035] In this embodiment, the guide block 33 is fixedly connected to the first mounting part 31, and the other end of the guide block 33 is provided with a second mounting part 34. The second mounting part 34 is detachably connected to the guide block 33. The position of the guide block 33 is restricted by the cooperation of the first mounting part 31 and the second mounting part 34 to prevent it from separating from the guide groove 5.

[0036] Furthermore, in this embodiment, a slot is provided on the guide block 33, and two inserts 35 that cooperate with the slot are fixedly provided on the second mounting part 34. An elastic member 36 is provided between the two inserts 35, and a slot that cooperates with the elastic member 36 is provided in the slot. By providing the elastic member 36 to cooperate with the slot, the second mounting part 34 is prevented from separating from the guide block 33. Under normal conditions, one or both of the first mounting part 31 and the second mounting part 34 are in contact with the outer wall of the connecting plate 1.

[0037] In this embodiment, the elastic element 36 includes two elastic arms 361, which are fixedly connected to form a V-shaped structure. The upper end of the V-shaped structure is fixedly connected to the second mounting part 34. Each elastic arm 361 is fixedly provided with a latching part 362 that cooperates with the slot. When the two elastic arms 361 are subjected to force, the included angle of the V-shaped structure becomes smaller, and the two latching parts 362 gradually separate from the slot, so that the second mounting part 34, the guide block 33 and the first mounting part 31 can be removed and replaced.

[0038] It should be noted that, in this embodiment, two abutting parts 37 are slidably disposed inside the second mounting part 34, and a button 38 is also slidably disposed inside the second mounting part 34. The button 38 is fixedly connected to the two abutting parts 37, and the other end of the button 38 passes through the second mounting part 34 and extends to its outside. By pressing the button 38, the two abutting parts 37 are moved, and the two abutting parts 37 apply force to the two elastic arms 361 respectively. The included angle of the V-shaped structure becomes smaller, and the two latching parts 362 gradually separate from the slots. The second mounting part 34, the guide block 33, and the first mounting part 31 can be removed and replaced. In some embodiments, the button 38 and the second mounting part 34 are provided with springs to facilitate the reset of the button 38.

[0039] In this embodiment, the limiting mechanism 4 includes a plurality of mounting holes 41 formed on the connecting plate 1. The first mounting part 31 is movably inserted with a pin 42 corresponding to the mounting hole 41. After adjusting the position of the buckle assembly 3, the pin 42 is inserted into the mounting hole 41 to fix the position of the buckle assembly 3 and prevent the position of the buckle assembly 3 from changing after being subjected to force.

[0040] Furthermore, in this embodiment, a spring 43 is provided between the pin 42 and the first mounting part 31, and a dustproof plate 44 that cooperates with the first mounting part 31 is fixedly provided on the pin 42. The other end of the dustproof plate 44 is connected to an auxiliary component 45 that is convenient for workers to hold. The spring 43 applies force to the pin 42 to prevent the pin 42 from separating from the mounting hole 41. The auxiliary component 45 is provided to facilitate the operator to separate the pin 42 from the mounting hole 41, thereby adjusting the position of the buckle assembly 3.

[0041] In this embodiment, limit grooves 11 are provided on both sides of the connecting plate 1. Limiting blocks 12 that cooperate with the limit grooves are fixedly provided on the first mounting part 31 and the second mounting part 34. By cooperating with the limit grooves 11 and the limit blocks 12, the force on the buckling assembly 3 is shared and the force is distributed to the connecting plate 1, so as to avoid the guide block 33 being subjected to excessive force and thus accelerating wear.

[0042] This invention also proposes a method for hoisting a reheat boiler steel structure, including the aforementioned reheat boiler steel structure hoisting structure, and further including the following steps.

[0043] S1. Connect the through hole 2 of the hoisting structure connecting plate 1 to the hoisting rope of the hoisting device;

[0044] S2. The external auxiliary component 45 drives the pin 42 to separate from the mounting hole 41, moves the buckle assembly 3, and adjusts the position of the two buckle assemblies 3.

[0045] S3. Connect the hoisting rope through the buckle assembly 3, and then use the hoisting rope to tie the steel structure to the steel structure for hoisting.

[0046] S4. When the steel structure is large in volume and heavy in weight, adjust the position of the two buckle components 3 to reduce the distance between them, so that the two lifting ropes can be tied to the same steel structure to avoid individual steel structures being overweight and affecting the hoisting.

[0047] The above description is only a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
