Description

Technical Field

[0001] The invention relates to the field of equipment installation engineering, and in particular to a construction method for hoisting irregular components with a novel hoisting beam. Background Art

[0002] The construction site often encounters difficulties in installing components and equipment in the factory under space-constrained environments, especially when the components are in place with a certain spatial angle, which brings certain difficulties to the installation and adjustment. The construction space of the air mixing chamber factory in this project is small, involving more cross-operations, and there are many oversized special-shaped pipe fittings. Most of the special-shaped pipe fittings need to be adjusted and installed using hand winches. It is time-consuming and labor-intensive. The S-shaped pipe elbow is particularly difficult to place. The S-shaped pipe elbow weighs 20 tons. Since it is difficult to cast the internal refractory materials after it is in place, the refractory materials must be completed before lifting, and the total weight reaches 41 tons. Due to the small construction space and complex structure of the air mixing chamber, it is impossible to use the double crane lifting method for lifting. The traditional lifting method is to use 4 sets of hand winches in conjunction with the crane for lifting. Moreover, it is inconvenient to use the manual winch after lifting. It is difficult to adjust the construction at high places, which is time-consuming and labor-intensive, and the effect is poor. In addition, high-altitude operations bring great safety risks.

[0022] In order to make the purpose, technical solution and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0023] It is difficult to hoist irregular components in a confined space. Usually, irregular components are hoisted by two cranes. The working space of the air mixing chamber of some projects is small and cannot accommodate the standing space of two cranes. Therefore, the traditional hoisting method is used to hoist large irregular components, using a hand chain hoist to adjust the components and install them in place. This traditional hoisting solution is difficult to operate the hand chain hoist after lifting, has poor installation accuracy and low efficiency. For the above situation, please refer to Figure 1-6 An embodiment of the present invention provides a beam hanging device, including a beam hanging 1 and a winch 2.

[0024] The hanging beam 1 is a frame-type structure. The upper part of the hanging beam 1 is provided with a top hanging lug 11, which is used to connect with the main hook of the crane. There are four top hanging lugs 11, two of which are welded on one side of the hanging beam 1, and the other two are welded on the other side of the hanging beam 1, so as to ensure sufficient force and safety during the lifting process.

[0025] The upper part of the suspension beam 1 has a slide rail 12 extending in the left-right direction, and a slidable support 13 is installed on the upper part of the slide rail 12. The support 13 is used for the installation of the winch 2, so as to adjust the position of the winch 2 on the suspension beam 1. There are two slide rails 12, and the two slide rails 12 are arranged in parallel along the front-to-back direction. Both slide rails 12 include two track monomers, and both track monomers extend in the left-to-right direction, and the two track monomers are arranged in parallel along the front-to-back direction. There are four supports 13, and every two supports 13 are slidably installed on the same slide rail 12. Both ends of each slide rail 12 have a limit stop 14 to prevent the support 13 from detaching from the slide rail 12 when sliding. The limit stop 14 is arranged on the front and rear sides of each slide rail 12. The side of each slide rail 12 has a plurality of first positioning pin holes 121 evenly spaced in the left-right direction, and the side of the support 13 has a second positioning pin hole 131, so that after the position of the winch 2 on the suspension beam 1 is adjusted, a positioning pin is inserted to fix the position of the winch 2. There are two second positioning pin holes 131, which are respectively arranged on the left and right sides of the support 13.

[0026] There are multiple winches 2, such as four winches 2, namely winches 1# 21, winches 2# 22, winches 3# 23, and winches 4# 24. Each winch 2 is installed on the upper part of each support 13. The position of each winch 2 corresponds to the position of each lifting lug on the hoisted component in the vertical direction. Each winch 2 has a hook 25, which is used to connect with the lifting lug. The hoisted component includes a special-shaped component or equipment such as an S-shaped pipe elbow.

[0027] The traditional hoisting method uses a crane in conjunction with a hand winch for hoisting, which is not only time-consuming, but also inconvenient to operate with a manual winch after hoisting, difficult to adjust at high altitudes, time-consuming and labor-intensive, and ineffective, and high-altitude operations bring great safety risks. After the lifting beam 1 of the present invention is lifted, the spatial angle of the hoisted component can be adjusted by the winch 2, which can be applied to the construction of irregular components and solve the problem that irregular components such as S-shaped pipe elbows are difficult to hoist and difficult to weld. Moreover, when the lifting operation surface is met, different lifting beams 1 can be welded according to the weight of the hoisted component, and different winches 2 can be selected. The present invention makes the lifting operation simpler and can be retained after use for continued use in production hoisting.

[0028] The embodiment of the present invention provides a construction method for hoisting an irregular component using a novel hanging beam. The construction method adopts the above-mentioned hanging beam device and comprises the following steps:

[0029] (1) The hoist 2 is installed on the lifting beam 1 so that the position of the hoist 2 corresponds to the position of the lifting lug on the hoisted component in the vertical direction.

[0030] Before starting the above steps, design and manufacture the hanging beam 1 according to the weight and dimensions of the hoisted component; select the winch 2 and the crane; calculate the total weight of the hoisted component, the hanging beam 1 and the components on the hanging beam 1, and require that the total weight is ≤ the lifting capacity of the crane.

[0031] In the above steps, the hoist 2 is slidably mounted on the hanging beam 1, and then the position of the hoist 2 is adjusted by sliding the hoist 2, so that the position of the hoist 2 corresponds to the position of the lifting lug on the hoisted component in the vertical direction. Optionally, four hoists 2 are respectively mounted on four supports 13, and then the positions of the four hoists 2 are adjusted by sliding the four hoists 2 respectively, so that the positions of the four hoists 2 correspond to the positions of the four lifting lugs on the hoisted component in the vertical direction. The above process is to ensure that the hanging beam 1 and the hoist 2 reach a balanced state after lifting. Further, after adjusting the position of the hoist 2, the position of the hoist 2 is fixed. Optionally, the position of the hoist 2 is fixed by inserting the locating pin into the second locating pin hole 131 and the first locating pin hole 121. The above process is to ensure that the hanging beam 1 and the hoist 2 reach a balanced state after lifting.

[0032] (2) Connect the winch 2 to the lifting lugs accordingly, and connect the crane to the lifting beam 1.

[0033] In the above steps, the winch 2 is connected with the lifting hook 25 and the lifting eye.

[0034] (3) Lift the hoisted component and adjust the spatial angle of the hoisted component so that the hoisted component reaches the specified position and is at the set spatial angle.

[0035] In the above steps, the hoisted component is lifted by controlling the crane and the hoisting machine 2. The spatial angle of the hoisted component is adjusted by controlling the hoisting machine 2.

[0036] Lifting the hoisted component includes: using the winch 2 to lift the hoisted component to a preset height, and checking whether there is any abnormality in the connection status between the winch 2 and the hoisted component. If there is an abnormality, stop lifting the hoisted component and make adjustments. If there is no abnormality, continue lifting the hoisted component. Wherein, slowly lift the hoisted component to a preset height. The preset height is 100-200mm. Further, check whether there is any abnormality in the connection status between the winch 2 and the hoisted component, including: check whether the center of gravity of the hoisted component is always kept within the control range of the lifting point of the lifting beam 1.

[0037] Adjusting the spatial angle of the suspended component includes: controlling each winch 2 disposed on the left side of the suspended component to lift or lower the suspended component, and / or controlling each winch 2 disposed on the right side of the suspended component to lower or lift the suspended component, thereby adjusting the rightward roll angle or the leftward roll angle of the suspended component. In other words, the roll angle of the suspended component is adjusted by controlling the winches 2 on the left and right sides. Optionally, by controlling the 1# winch 21 and the 3# winch 23 to lift the suspended component, and the 2# winch 22 and the 4# winch 24 to lower the suspended component, the suspended component rolls to the right, and the rightward roll angle of the suspended component is adjusted. The opposite operation causes the suspended component to roll to the left, and the leftward roll angle of the suspended component is adjusted.

[0038] Adjusting the spatial angle of the hoisted component also includes: controlling each winch 2 disposed on the front side of the hoisted component to lift or lower the hoisted component, and / or controlling each winch 2 disposed on the rear side of the hoisted component to lower or lift the hoisted component, thereby adjusting the front side pitch angle or front side pitch angle of the hoisted component. In other words, the pitch angle of the hoisted component is adjusted by controlling the winches 2 on both sides. Optionally, the hoisted component is lifted by controlling the 1# winch 21 and the 2# winch 22, and the hoisted component is lowered by controlling the 3# winch 23 and the 4# winch 24, so that the front side of the hoisted component pitches downward, and the front side pitch angle of the hoisted component is adjusted. The opposite operation causes the front side of the hoisted component to pitch upward, and the front side pitch angle of the hoisted component is adjusted.

[0039] Adjusting the spatial angle of the hoisted component also includes: fine-tuning the steering of a main hook on the crane connected to the hoisting beam 1 .

[0040] The above adjustment of the spatial angle of the hoisted component can be achieved by observing from the ground and the high-altitude platform, and by remotely controlling the lifting and lowering of the hooks on the four winches 2.

[0041] (4) Fix the components to be hoisted.

[0042] After the above steps are completed, the hook on the hoist 2 is disengaged from the lifting lug on the hoisted component, and then the hanging beam 1 and the components on the hanging beam 1 are hoisted to the lifting position for subsequent construction use.

[0043] In summary, the present invention uses a single crane to lift the hanging beam 1, and uses four winches 2 on the hanging beam 1 to adjust the spatial angle of the hoisted components and hoist them into place, which solves the installation problem of large special-shaped components in a confined space due to the spatial angle, and realizes the rapid installation of large special-shaped components in a confined space. In particular, it solves the installation problem of the S-shaped pipe elbow connecting the drying rotary kiln and the roasting rotary kiln under the conditions of complex structure, compact layout and narrow space in the mixing chamber factory, and realizes the rapid installation and rapid butt welding of the S-shaped pipe elbow. In addition, the present invention not only speeds up the installation speed of the hoisted components, but also saves the crane required for installation, improves the installation accuracy, and the hanging beam device can be reused, with high efficiency, reducing construction costs.
