Description

Technical Field

[0001] The invention relates to the technical field of steel structure construction, and in particular to a reheat boiler steel structure hoisting structure and a method thereof. Background Art

[0002] In essence, it is a steam superheater that reheats the low-pressure steam that has done work to a certain temperature. The function of the reheater further improves the thermal efficiency of the power plant cycle and controls the steam temperature of the last-stage blades of the turbine within the allowable range. The reheater is a heater in the boiler that heats the water vapor coming out of the turbine into superheated steam. The reheater has two functions: one is to reduce the humidity of the water vapor, which is beneficial to protecting the turbine blades; the other is to improve the relative internal efficiency and absolute internal efficiency of the turbine. When installing the steel structure of the reheat boiler, a lifting device is required to lift the steel structure of the boiler to the required position for installation.

[0003] Existing lifting devices usually need to use steel structure lifting devices to fix the steel structure when lifting it to prevent the steel structure from falling off during lifting. However, the steel structures of reheat boilers are not only of different sizes, but also of different weights. During lifting, some overweight steel structures are prone to falling off due to unstable center of gravity, which will not only damage the steel structure but also cause safety accidents. Summary of the invention

[0004] The purpose of the present invention is to solve the problem in the prior art that some overweight steel structures are prone to fall off due to unstable center of gravity during lifting, which not only causes damage to the steel structure but also leads to safety accidents. A reheat boiler steel structure lifting structure and method are proposed.

[0005] In order to achieve the above object, the present invention adopts the following technical solutions:

[0006] A reheat boiler steel structure hoisting structure is designed, comprising a connecting plate connected to a hoisting rope of a hoisting device, a through hole matching the hoisting rope is opened on the connecting plate, two buckle assemblies are arranged on the connecting plate, and the buckle assemblies are connected to the hoisting rope for hoisting the steel structure;

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

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

[0010] Furthermore, a slot is provided on the guide block, two plug blocks matching the slot are fixedly provided on the second mounting portion, an elastic member is provided between the two plug blocks, and a card slot matching the elastic member is provided in the slot.

[0011] Furthermore, the elastic member includes two elastic arms, the two elastic arms 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 portion, and the elastic arms are fixedly provided with a buckle portion that cooperates with the slot.

[0012] Furthermore, two abutment parts are slidably provided in the second mounting part, and a button is also slidably provided in the second mounting part. The button is fixedly connected to the two abutment parts, and the other end of the button passes through the second mounting part and extends to the outside thereof.

[0013] Furthermore, the limiting mechanism includes a plurality of mounting holes formed on the connecting plate, and the first mounting portion is movably connected with pins corresponding to the mounting holes.

[0019] S3, connect the lifting ropes through the buckle assembly, and use the lifting ropes to bundle the steel structures for lifting;

[0020] S4. When the steel structure is large in size and heavy in weight, adjust the position of the two clip assemblies to reduce the distance between them, so that the two lifting ropes can be tied to the same steel structure to avoid affecting the lifting due to overweight of individual steel structures.

[0021] The invention provides a reheat boiler steel structure hoisting structure and method thereof, which has the following beneficial effects:

DETAILED DESCRIPTION

[0030] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0031] Reference Figure 1-5 A reheat boiler steel structure hoisting structure, comprising a connecting plate 1 connected to a hoisting device hoisting rope, a through hole 2 cooperating with the hoisting rope is opened on the connecting plate 1, two buckle assemblies 3 are arranged on the connecting plate 1, and the buckle assemblies 3 are connected to the hoisting rope for hoisting the steel structure;

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

[0033] In the present invention, when lifting a lighter steel structure through two buckle assemblies 3, the steel structure can be lifted simultaneously through the two buckle assemblies 3. During lifting, the lifting ropes string two steel beams together at the same time, and are bundled and lifted according to the principle of high to low elevation (that is, the steel beam with the highest elevation is lifted on the top layer of the same lifting, and so on, the lowest elevation is lifted on the bottom layer). At the same time, the principle of long steel beams at the bottom and short steel beams at the top is taken into account during lifting, which is conducive to the positioning of steel beams and reducing the labor intensity of construction personnel, improving work efficiency and shortening construction period, thereby achieving the effect of reducing costs. When lifting an overweight steel structure, the lifting ropes on the two buckle assemblies 3 are tied to the overweight steel structure, which can share the weight and prevent a single buckle assembly from being damaged by excessive force.

[0034] Furthermore, in this embodiment, a guide groove 5 cooperating with the snap assembly 3 is provided on the connecting plate 1, and the snap assembly 3 also includes a guide block 33 cooperating with the guide groove 5. By setting the guide block 33 and cooperating with the guide groove 5, the force applied to the snap assembly 3 is transmitted to the connecting plate 1, and then transmitted to the lifting device.

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

[0036] Furthermore, in the present embodiment, a slot is provided on the guide block 33, two plug blocks 35 matching the slot are fixedly provided on the second mounting portion 34, an elastic member 36 is provided between the two plug blocks 35, and a card slot matching the elastic member 36 is provided in the slot. The elastic member 36 is provided to cooperate with the card slot to prevent the second mounting portion 34 from separating and falling off from the guide block 33. Under normal conditions, one or both of the first mounting portion 31 and the second mounting portion 34 are in contact with the outer wall of the connecting plate 1.

[0037] In this embodiment, the elastic member 36 includes two elastic arms 361, and the two elastic arms 361 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 portion 34. The elastic arms 361 are fixedly provided with a snap portion 362 that cooperates with the slot. When the two elastic arms 361 are subjected to force, the angle of the V-shaped structure becomes smaller, and the two snap portions 362 are gradually separated from the slot, so that the second mounting portion 34, the guide block 33 and the first mounting portion 31 can be removed for replacement.

[0038] It should be noted that, in the present embodiment, two abutment portions 37 are slidably provided in the second mounting portion 34, and a button 38 is also slidably provided in the second mounting portion 34. The button 38 is fixedly connected to the two abutment portions 37, and the other end of the button 38 passes through the second mounting portion 34 and extends to the outside thereof. By pressing the button 38, the two abutment portions 37 are driven to move, and the two abutment portions 37 apply force to the two elastic arms 361 respectively, and the angle of the V-shaped structure becomes smaller. The two buckle portions 362 are gradually separated from the card slot, and the second mounting portion 34, the guide block 33 and the first mounting portion 31 can be removed for replacement. In some embodiments, a spring is provided in the button 38 and the second mounting portion 34 to facilitate resetting the button 38.

[0039] In this embodiment, the limiting mechanism 4 includes a plurality of mounting holes 41 opened on the connecting plate 1, and a pin 42 corresponding to the mounting hole 41 is movably plugged into the first mounting portion 31. After the position of the buckle assembly 3 is adjusted, the position of the buckle assembly 3 can be fixed by plugging the pin 42 into the mounting hole 41 to prevent the position of the buckle assembly 3 from changing after being subjected to force.

[0040] In addition, in the present embodiment, a spring 43 is provided between the latch 42 and the first mounting portion 31, a dustproof plate 44 matching the first mounting portion 31 is fixedly provided on the latch 42, and the other end of the dustproof plate 44 is connected to an auxiliary component 45 for the convenience of workers to hold. The spring 43 applies force to the latch 42 to prevent the latch 42 from being separated from the mounting hole 41. The auxiliary component 45 is provided to facilitate the operator to separate the latch 42 from the mounting hole 41, thereby adjusting the position of the buckle assembly 3.

[0041] In this embodiment, limiting grooves 11 are provided on both sides of the connecting plate 1, and limiting blocks 12 that cooperate with the limiting grooves are fixedly arranged on the first mounting portion 31 and the second mounting portion 34. The limiting grooves 11 cooperate with the limiting blocks 12 to share the force exerted on the buckle assembly 3 and disperse the force to the connecting plate 1, thereby preventing the guide block 33 from being subjected to excessive force and causing accelerated wear.

[0042] The present invention also provides a method for hoisting a reheat boiler steel structure, comprising the above-mentioned hoisting structure for the reheat boiler steel structure, and further comprising the following steps:

[0043] S1, connecting the through hole 2 of the lifting structure connecting plate 1 with the lifting rope of the lifting device;
