[0030] The principles and features of this utility model are described below with reference to the accompanying drawings. The examples given are only for explaining this utility model and are not intended to limit the scope of this utility model.

[0031] Example 1

[0032] like Figure 1 As shown, an installation tool for a steam soot blower barrel includes a crossarm 1, a lifting lug 2, a fixing plate 4, and a support plate 5. A fixing plate 4 is provided at the top of each end of the crossarm 1, and a lifting lug 2 is provided at the top of each of the two fixing plates 4. A support plate 5 is fixedly provided at the middle of the upper part of the crossarm 1. The support plate 5 has a semi-arc structure.

[0033] Specifically, place this tool under the barrel, and then place the barrel on the support plate 5, ensuring the barrel's curvature matches the semi-circular structure of the support plate 5 to secure it. Then, use other mechanical tools to lift this tool, allowing it to raise and support the barrel. The entire barrel installation can then be completed by two to three people.

[0034] like Figure 1 As shown, the thickness of the support plate 5 is greater than 5mm, and the height of the fixing point between the support plate 5 and the crossarm 1 is greater than 5mm.

[0035] Specifically, the height of the fixing point between the support plate 5 and the crossarm 1 is 5mm higher, so that the support plate 5 is more stably fixed on the crossarm 1 and the fixing connection is less likely to be damaged.

[0036] like Figure 1 As shown, a reinforcing rib 3 is provided at the bottom of the crossarm 1. The reinforcing rib 3 is triangular in shape and is provided at the bottom of the crossarm 1.

[0037] Specifically, the crossarm 1, as the main load-bearing structure, bears the weight of the gun barrel and is made of channel steel. In order to enhance the load-bearing capacity of the structure, a reinforcing rib 3 is used at the bottom of the crossarm 1 for reinforcement, so that the stress on the crossarm 1 can be reduced when the tool is working, and the deformation or damage caused by excessive stress on the crossarm 1 can be reduced.

[0038] In this embodiment, the crossarm 1 is selected as No. 8 C-shaped channel steel with a length of 0.8 meters, the barrel weight is 200 kg, and the reinforcing rib 3 is used as reinforcement and is not included in the strength calculation.

[0039] Strength calculation:

[0040] According to the table, the waist thickness t1 of the No. 8 C-shaped channel steel is 0.045 m, and the moment of inertia I X = 101 * 10 -8 m 4 , the cross-sectional modulus W X = 25.3 * 10 -6 m 3 , and the static moment Q X = 14.5 * 10 -6 m 3

[0041] The allowable bending stress of Q235B material is taken as σ = 160 MPa, and the allowable shear stress is taken as t = 100 MPa

[0042] Bending stress:

[0043] σ max = M / V x = 2000 N * 0.4 m / 25.3 * 10 -6 m 3 = 31.6 * 10 6 N / m 2 <160 MPa

[0044] Shear stress:

[0045] t max = (V * Q X ) / (I X *t1) = (2000 N * 14.5 * 10 -6 m 3 ) / (101 * 10 -8 m4* 0.045 m) = 0.638 * 10 6 N / m 2 <100 MPa

[0046] Therefore, the No. 8 C-shaped channel steel is selected as the cross arm 1 to bear the weight of the gun barrel, and the strength meets the requirements.

[0047] As shown in the figure, the two lifting lugs 2 are provided with through holes, and the lifting lug 2 and the fixing plate 4 are made of steel structure material, and the lifting lug 2 is fixedly welded on the top of the fixing plate 4. Figure 1 Specifically, the through holes are provided on the two lifting lugs 2, so that other mechanical tools can be connected with the lifting lugs 2, thereby replacing the gun barrel by using the tool. The fixing plate 4 with a certain height is welded on both sides of the cross arm 1, and the lifting lug 2 is fixedly welded on the top of the fixing plate 4. By arranging the reinforcing ribs 3 and the fixing plate 4 on the cross arm 1, the tool can reduce the stress of the cross arm 1 during work, and reduce the deformation or damage of the cross arm 1 due to too much stress.

[0048] ​

[0049] As shown in Figure 1 The weld height of the lug 2 and the fixing plate 4 is higher than 8mm.

[0050] Specifically, the weld height of the lug 2 and the fixing plate 4 is higher than 8mm. The connection between the lug 2 and the fixing plate 4 can be reinforced. The lug 2 and the fixing plate 4 are not easy to crack during work, reducing the risk of weld cracking.

[0051] As shown in Figure 1 The lifting assembly 6 lug 2 can be detachably connected.

[0052] Specifically, the lifting assembly 6 is detachably arranged on the lug 2, so that the installation tool can be disassembled and arranged separately, and can also be used separately, so that the lifting assembly 6 can also be used in other cases.

[0053] As shown in Figure 1 The lifting assembly 6 includes a chain hoist 61, a steel wire rope 62, and two lifting rings 63. The two lifting rings 63 are respectively arranged through the through holes of the two lugs 2 and are detachably connected to the two lugs 2. The two ends of the steel wire rope 62 are detachably connected to the two lifting rings 63. The connecting end of the chain hoist 61 is detachably connected to the steel wire rope 62.

[0054] Specifically, the two lifting rings 63 are detachably connected to the two lugs 2, the two ends of the steel wire rope 62 are detachably connected to the two lifting rings 63, and the connecting end of the chain hoist 61 is hooked on the steel wire rope 62. The force is transmitted to the two lifting rings 63 by lifting the chain hoist 61. Since the two lifting rings 63 are connected to the two lugs 2, the lifting force acts on the two lugs 2, thereby lifting the entire installation tool. Since the barrel is placed on the installation tool, the barrel is lifted until it reaches the installation position. Then, two or three people install the barrel until the installation is completed. Then, the lifting assembly 6 is detached from the installation tool. The entire installation process reduces at least three people compared to the original installation process, and the entire installation process saves time and effort.

[0055] As shown in Figure 1 The supporting plate 5 is made of steel structure material, and the supporting plate 5 is a concave semicircular structure. The concave curvature of the supporting plate 5 is adapted to the curvature of the steam soot blower barrel.

[0056] Specifically, the supporting plate 5 is made of steel structure material and is designed at the center point of the cross arm 1. The supporting plate 5 is a semicircular steel plate, which mainly serves to lift the barrel and uniformly bear the force of the barrel, and also serves to fix the barrel.

[0057] As shown in Figure 1 The cross arm 1 is made of steel structure material, and the length direction of the cross arm 1 exceeds the diameter length of the cross section of the soot blower shell.

[0058] Specifically, the cross arm 1 is used as a main force bearing structure and bears the weight of the gun barrel, is made of steel structure material, and the length direction of the cross arm 1 exceeds the cross section diameter length of the soot blower shell, so that the gun barrel can be placed on the cross arm 1, and the gun barrel is convenient to replace.

[0059] As shown in Figure 1 The bottom of the fixed plate 4 is fixedly welded at both ends of the cross arm 1, and the distance between the two fixed plates 4 exceeds the cross section diameter length of the soot blower shell.

[0060] Specifically, the bottom of the fixed plate 4 is fixedly welded at both ends of the cross arm 1. The force of the cross arm 1 is shared, so that the force of the cross arm 1 is reduced, and the damage rate of the cross arm 1 is reduced. The distance between the two fixed plates 4 exceeds the cross section diameter length of the soot blower shell, so that the gun barrel can be placed between the two fixed plates 4, and the gun barrel is convenient to replace.

[0061] The beneficial effects of the embodiment are that the tool is placed below the gun barrel, and the gun barrel is placed on the supporting plate 5, the supporting plate 5 adopts a semicircular structure and is used for lifting the gun barrel, so that the gun barrel is uniformly stressed and the gun barrel is fixed. Then, the installation tool is lifted by the hoisting assembly 6, so that the installation tool lifts the gun barrel. Then, two or three people can complete the entire gun barrel installation, more than three people are reduced than the original, the entire installation process is time-saving and labor-saving, and the installation process is safer.

[0062] The working process of the embodiment is that the tool is placed below the gun barrel, and the gun barrel is placed on the supporting plate 5, the supporting plate 5 adopts a semicircular structure and is used for lifting the gun barrel, so that the gun barrel is uniformly stressed and the gun barrel is fixed.
