Description

Technical Field

[0001] This invention relates to the field of large-scale precision equipment erection technology, specifically to a three-dimensional distributed load reduction erection structure, erection system, and erection method. Background Technology

[0002] For large and precision electronic equipment such as ultra-large radars, ultra-large cranes are often used for high-difficulty hoisting operations during the installation process. To ensure high precision after installation, the following methods are usually adopted:

[0003] 1. A large amount of manual adjustment work is carried out during the hoisting process. Adjustment devices are added to the parts that need adjustment, and adjustments are made while measuring. There are usually tens of thousands of adjustment points for ultra-large equipment. This method is not only time-consuming and labor-intensive, but the adjustment process usually takes place at a height of tens of meters, which is labor-intensive and dangerous.

[0004] 2. To reduce adjustment workload, some key radar components are currently machined using high-precision machine tools, allocating assembly precision down to the component level to facilitate final installation. This method ensures consistency in component machining precision, achieving good assembly results after machining. However, due to differences between the machine tool processing environment and the installation environment (e.g., expansion or contraction of components caused by humid heat effects due to varying temperature and humidity), stress release from welding caused by vibration during transportation, and natural aging due to prolonged placement of workpieces during installation, the high precision achieved during machining cannot be maintained during installation. Consequently, inconsistencies in deformation between components may still occur during installation.

[0005] 3. Based on the aforementioned high-precision machine tool processing, increasing the length of components within the allowable transportation range and reducing the number of mounting joints can alleviate the deformation inconsistency caused by welding stress release to some extent. This method is currently widely used. However, due to factors such as transportation conditions, the maximum length of key components is usually limited to a few dozen meters. Moreover, the longer the component, the larger the tonnage of the hoisting equipment required, and the time and hoisting costs increase exponentially.

[0006] Based on the above technical solutions, the current problems in the installation of large electronic equipment are as follows:

[0007] 1. Large electronic equipment requires the use of ultra-large cranes for hoisting, which is difficult, risky, costly and time-consuming.

[0008] 2. The erection process requires a large amount of manual adjustment and the participation of large cranes, which places extremely high demands on the engineering and technical experience of crane operators, on-site supervisors, and construction workers;

[0009] 3. Extensive manual adjustments increase construction time and costs, further increasing construction risks. Personal safety during construction must be carefully considered.

[0010] 4. Although the high-precision machining of key components involved in the erection reduces the difficulty of erection and installation, the large components use a lot of welding processes, and the release of welding stress still brings many difficulties to the erection and installation, and still requires a certain amount of manual adjustment.

[0011] 5. Increasing the length of key components can reduce the number of erection steps and shorten the erection time. However, due to limitations in processing conditions (machine tool size, processing plant size) and transportation conditions (transport vehicles, transportation roads, etc.), the length of components cannot be increased arbitrarily. In addition, it increases the requirements for hoisting equipment and increases time and hoisting costs. Summary of the Invention

[0012] In order to solve the technical problems existing in the background art, the present invention proposes a three-dimensional distributed load reduction erection structure, erection system and erection method.

[0013] The three-dimensional distributed load reduction support structure proposed in this invention includes: a support unit, an adjustable base A on the side of the support unit, and an adjustable base B on the bottom surface of the support unit;

[0014] The adjustable base A includes a left base A and a right base A. Both the left base A and the right base A are right dihedral structures. The left base A and the right base A are arranged back to back so that the included angles of the two bases face towards the two sides of the supporting unit. On the side of the two right angles of the left base A that are close to each other, and on the side of the two right angles of the right base A that are close to each other, there are ball bearings A that are higher than their surfaces and can rotate freely. Each ball bearing A is supported by an elastic element A encapsulated inside the adjustable base A.

[0015] The lower surface of the adjustable base B has balls B that are raised above its surface and can rotate freely, and each ball B is supported by an elastic element B encapsulated in the adjustable base B.

[0016] Preferably, both the adjustable base A and the adjustable base B are provided with mounting holes.

[0017] Preferably, both the left base A and the right base A include a base plate A and a cover plate A. The base plate A has a right-angled diagonal structure, and multiple channels are arranged in an array on the sides of the two right-angled faces that are close to each other. Elastic elements A are correspondingly arranged in each channel. There are two cover plates A, which are located inside the included angle of the base plate A. The two cover plates A are respectively opposite to and fixed to the two right-angled faces of the base plate A. Each cover plate A has a hole corresponding to each channel. Ball bearings A are correspondingly arranged in each hole and supported by the corresponding elastic elements A so that they are partially exposed in the hole and higher than the surface of the cover plate A.

[0018] Preferably, the elastic element A includes a spring and a ball bearing fixed to the end of the spring to abut against the ball A.

[0019] Preferably, the cover plate A is fixed to the base plate A by screws.

[0020] Preferably, the adjustable base B includes a base plate B and a cover plate B. The cover plate B is opposite to and fixed to the base plate B. The base plate B has a plurality of channels arranged on the side of the plate closest to the cover plate B. The cover plate B has holes that correspond one-to-one with each channel. Elastic elements B are arranged one-to-one in each channel, and ball bearings B are arranged one-to-one in each hole and supported by the corresponding elastic elements B so that they are partially exposed in the holes and higher than the surface of the cover plate B.

[0021] Preferably, the elastic element B includes a spring and a ball bearing fixed to the end of the spring to abut against the ball B.

[0022] Preferably, the cover plate B is fixed to the base plate B by screws.

[0023] Preferably, the side portion of the mounting unit located between the left base A and the right base A is also provided with an adjustable base B.

[0024] Preferably, both adjustable base A and adjustable base B are assembled onto the erection unit using fasteners.

[0025] The three-dimensional distributed load reduction erection system proposed in this invention includes: an installation rail and a three-dimensional distributed load reduction erection structure as described above;

[0026] Multiple mounting rails are installed and fixed vertically side by side;

[0027] Multiple mounting units are provided and are arranged on one side of the mounting rail arrangement direction. The adjustable base B at the bottom of each mounting unit abuts against the component located below it. The two right-angled surfaces of the left base A on the side of each mounting unit abut against the front and side of one of the mounting rails, respectively. The two right-angled surfaces of the right base A on each mounting unit abut against the front and side of another mounting rail, respectively. All left bases A and right bases A are fixed to the corresponding mounting rails by fasteners.

[0028] Preferably, the fastener includes a bolt and a nut that mates with the bolt.

[0029] Preferably, the mounting rail includes multiple guide rail segments, which are detachably fixed together by connecting plates.

[0030] Preferably, the mounting rail is an I-beam type rail.

[0031] The three-dimensional distributed load reduction method proposed in this invention includes the following steps:

[0032] S1. Construct the basic platform;

[0033] S2. Install the mounting rails on the base platform, ensuring that all mounting rails are vertical and parallel to each other;

[0034] S3. Install the erection unit: During installation, first hoist the erection unit to the top of the mounting rail and adjust its position so that the two right-angled surfaces of the left base A on the side of the erection unit are respectively against the front and side of one of the mounting rails, and the two right-angled surfaces of the right base A on the side of the erection unit are respectively against the front and side of the other mounting rail; after adjusting the position of the erection unit, let the erection unit slide down along the mounting rail to the installation position, and pre-tighten it to the corresponding mounting rail with fasteners;

[0035] S4. Following the method in S3, hoist all the erection units into the corresponding installation positions in sequence, and pre-tighten them on the corresponding installation rails with fasteners.

[0036] S5. Adjust the position of each erection unit in sequence to ensure that its positional accuracy meets the requirements; and tighten the corresponding fasteners after the position of the erection unit meets the requirements.

[0037] Preferably, the base platform has pre-drilled studs for mounting rail assembly, and the mounting rail has assembly holes. After the assembly holes on the mounting rail pass through the studs, they are locked with nuts to complete the installation.

[0038] In this invention, by setting an adjustable base A on the side of the erection unit and an adjustable base B on its bottom surface, the gravitational load on the erection unit is reduced. Furthermore, by designing the structures of adjustable bases A and B, the erection unit has adjustment space in three dimensions. Through the load-reducing sliding of adjustable bases A and B in three dimensions, the erection unit can be easily and flexibly adjusted manually after being placed at the installation position without the need for a crane. This reduces hoisting work and significantly lessens the reliance on the professional expertise of on-site construction personnel. By placing multiple three-dimensional distributed load-reducing erection units one by one at their respective installation positions and then fastening them after adjustment, the rapid assembly of ultra-large, high-precision erection units can be achieved. Compared with existing technologies, it has the following advantages:

[0039] 1. The adoption of a three-dimensional distributed load reduction erection structure can shorten the length of the erection unit. Although the shortened length of the erection unit will lead to more assembly layers and thus larger assembly errors, these errors can be adjusted by the adjustable base A and adjustable base B on the erection unit. Therefore, during the erection process, a small-tonnage crane can be used to lift lighter erection units, making the erection process more flexible and improving erection efficiency. This solves the problems of large electronic equipment requiring the use of ultra-large cranes for hoisting, which result in high construction difficulty, high risk, high cost, and long time consumption.

[0040] 2. A three-dimensional distributed load reduction erection structure is adopted to provide a certain support load for the erection unit, reducing the adjustment force of the erection unit. By adjusting the number and type of elastic elements in adjustable base A and adjustable base B, the dependence on cranes is reduced during manual adjustment, and the difficulty and number of manual adjustments are reduced, making the adjustment process more flexible and controllable. This solves the problems of needing a lot of manual adjustment and large cranes during the erection process.

[0041] 3. By reducing the difficulty and frequency of manual adjustments, construction time and costs are reduced, construction risks are further lowered, and personal safety during construction is further guaranteed.

[0042] 4. The erection unit has adjustment functions in three directions: horizontal, vertical and normal, which can adapt to the problem of changes in the size of welded parts caused by the release of welding stress.

[0043] 5. The adoption of a three-dimensional distributed load reduction structure allows for the appropriate shortening of the length of key components, thus enabling better adaptation to both processing and transportation conditions. Attached Figure Description

[0061] Reference Figure 1-2 The three-dimensional distributed load reduction support structure proposed in this invention includes: support unit 1, an adjustable base A2 on the side of support unit 1, and an adjustable base B3 on the bottom surface of support unit 1. Both the adjustable base A2 and the adjustable base B3 are provided with mounting holes. The adjustable base A2 includes a left base A (21) and a right base A22.

[0062] Reference Figure 3-4 Both the left base A(21) and the right base A22 are right dihedral structures. The left base A(21) and the right base A22 are arranged back to back so that the included angles of the two are facing the two sides of the mounting unit 1 respectively. On the side of the two right angles of the left base A(21) that are close to each other, and on the side of the two right angles of the right base A22 that are close to each other, there are ball bearings A4 that are higher than their surfaces and can rotate freely. Each ball bearing A4 is supported by an elastic element A5 encapsulated inside the adjustable base A2 so that each ball bearing A4 has compression space in the direction perpendicular to its surface. The compression distance in this direction is the adjustment range in this direction during the subsequent installation of the mounting unit 1.

[0063] Reference Figure 5-6 Specifically: both the left base A(21) and the right base A22 include a base plate A20 and a cover plate A200. The base plate A20 is a right-angled diagonal structure, and multiple channels are arranged on the sides of the two right-angled surfaces that are close to each other. There are two cover plates A200, which are located inside the included angle of the base plate A20. The two cover plates A200 are respectively opposite to and fixed to the two right-angled surfaces of the base plate A20. Each cover plate A200 has a hole that corresponds to each channel. The elastic element A5 is arranged between the base plate A20 and the cover plate A200 and is arranged in each channel. The ball A4 is arranged in each hole and is supported by the corresponding elastic element A5 so that it is partially exposed in the hole and higher than the surface of the cover plate A200.

[0064] Reference Figure 7The lower surface of the adjustable base B3 has ball bearings B6 that are raised above its surface and can rotate freely. Each ball bearing B6 is separated by elastic elements B7 so that it has compression space in a direction perpendicular to its surface. The compression distance in this direction is the adjustment range in this direction during the subsequent installation of the mounting unit 1.

[0065] Reference Figure 8 Specifically: the adjustable base B3 includes a base plate B31 and a cover plate B32. The cover plate B32 is opposite to and fixed to the base plate B31. The base plate B31 has several channels arranged on the side of the plate closest to the cover plate B32. The cover plate B32 has holes that correspond one-to-one with each channel. The elastic element B7 is disposed between the base plate B31 and the cover plate B32 and is disposed one-to-one in each channel. The ball bearings B6 are disposed one-to-one in each hole and are supported by the corresponding elastic element B7 so that they are partially exposed in the hole and higher than the surface of the cover plate B32.

[0066] Reference Figure 9-10 The working principle of this invention is as follows: After each erection unit 1 is placed in the installation position, the adjustable bases A2 and B3 on each erection unit 1 allow it to slide in three dimensions with reduced load without the need for hoisting equipment, and the adjustment range in three dimensions can be controlled by the height of the ball bearings. Therefore, in actual production, by designing the arrangement and stiffness of the ball bearings A4, B6, and corresponding elastic elements A5 and B7, the support reaction force provided by the adjustable bases A2 and B3 to the erection unit 1 can be adjusted, thereby achieving the purpose of load reduction during the erection process. After the erection unit 1 is placed in the installation position, it has two gaps (widths t1 and t2) in both the horizontal and vertical directions. By designing the dimensions of the two gaps (i.e., the height of the ball bearings A4 and B6 above their respective surfaces), erection unit 1 with different adjustment ranges can be obtained.

[0067] By determining the support stiffness of the elastic elements within the adjustable base A2 and adjustable base B3, the load reduction after hoisting a single support element 1 can be determined. This allows for rapid manual adjustment based on actual construction conditions, enabling quick assembly between support frame units.

[0068] Reference Figure 11 In addition, to ensure the smooth rolling of the ball A4, the elastic element A5 in this embodiment includes a spring and a ball bearing fixed to the end of the spring to abut against the ball A4.

[0069] Reference Figure 12 Similarly, in order to ensure the smooth rolling of ball B6, the elastic element B7 in this embodiment includes a spring and a ball bearing fixed to the end of the spring to abut against ball B6.

[0070] In order to allow the elastic element A5 and the ball A4 to be disassembled and replaced separately, the cover plate A200 in this embodiment is fixed to the base plate A20 with screws. Similarly, in order to allow the elastic element B7 and the ball B6 to be disassembled and replaced separately, the cover plate B32 is fixed to the base plate B31 with screws.

[0071] In addition, when the lateral dimension of the mounting unit 1 is very large, in order to increase the stability of the mounting unit 1, this embodiment also provides an adjustable base B3 on the side of the mounting unit 1 located between the left base A (21) and the right base A22 to increase the number of mounting points.

[0072] In this embodiment, both the adjustable base A2 and the adjustable base B3 are assembled onto the mounting unit 1 by fasteners so that they can be freely assembled and disassembled.

[0073] Reference Figure 13-14 The three-dimensional distributed load reduction erection system proposed in this invention includes: an installation rail 8 and a three-dimensional distributed load reduction erection structure as described above;

[0074] Multiple mounting rails 8 are installed and fixed vertically side by side;

[0075] Multiple mounting units 1 are provided and are set on one side of the mounting rail 8. The adjustable base B3 at the bottom of each mounting unit 1 abuts against the component below it. The two right-angled surfaces of the left base A (21) on the side of each mounting unit 1 abut against the front and side of one of the mounting rails 8 respectively. The two right-angled surfaces of the right base A22 on the mounting unit 1 abut against the front and side of another mounting rail 8 respectively. All left bases A (21) and right bases A22 are installed on the corresponding mounting rails 8 by fasteners.

[0076] In this embodiment, the fastener includes a bolt and a nut that mates with the bolt. The specific installation method is as follows: one end of the bolt passes through the adjustable base A2 and the mounting rail 8 and is fastened to the nut.

[0077] In this embodiment, the mounting rail 8 includes multiple guide rail segments, which are detachably fixed together by connecting plates. The rail segments are processed in sections and then spliced ​​together after being transported to the site. This facilitates transportation and installation, and the length can be increased or decreased as needed.

[0078] In this embodiment, the mounting rail 8 is an I-beam type rail. One side of the mounting rail 8 is used to install the support unit 1, and the other side is used to fix it to the foundation platform.

[0079] Reference Figure 15 The three-dimensional distributed load reduction method proposed in this invention includes the following steps:

[0080] S1. Construct a foundation platform 9, which can be constructed from concrete or assembled from steel structures.

[0081] S2. Install the mounting rails 8 onto the base platform 9, ensuring that all mounting rails 8 are vertical and parallel to each other. The specific installation steps are as follows:

[0082] Pre-tighten all the mounting rails 8 onto the base platform 9, adjust the parallelism between the mounting rails 8, and finally tighten the fastening nuts completely.

[0083] S3. Hoist all the erection unit 1 to the top of the mounting rail 8 in sequence, and adjust the position of the erection unit 1 so that the two right-angled surfaces of the left base A (21) on the side of the erection unit 1 are respectively attached to the front and side of one of the mounting rails 8, and the two right-angled surfaces of the right base A22 on the side of the erection unit 1 are respectively attached to the front and side of the other mounting rail 8; after adjusting the position of the erection unit 1, let the erection unit 1 slide down along the mounting rail 8 to the installation position, and pre-tighten it to the corresponding mounting rail 8 with fasteners; the pre-tightening force should not affect the subsequent adjustment.

[0084] S4. Following the method in S3, hoist all the erection unit 1 into the corresponding installation position in sequence, and pre-fasten them to the corresponding installation rail 8 with fasteners.

[0085] S5. Adjust the position of each erection unit 1 in sequence to ensure that its positional accuracy meets the requirements; and tighten its corresponding fasteners after the erection unit position meets the requirements.

[0086] Because the adjustable bases A2 and B3 on each erection unit 1 reduce the gravitational load on the unit 1, each unit 1 can be easily and flexibly adjusted manually without the need for a crane. Once the positional accuracy of all erection unit 1 meets the requirements, the fasteners can be tightened to complete the assembly. Furthermore, during the tightening process, if there are gaps between adjacent erection unit 1s after adjustment, shims of appropriate thickness can be inserted into the gaps before tightening the corresponding fasteners.

[0087] In this embodiment, the base platform 9 is pre-studded for the installation of the mounting rail 8 during the construction process. The mounting rail 8 is provided with assembly holes. After the assembly holes on the mounting rail 8 pass through the studs, they are locked with nuts to complete the installation.

[0088] As can be seen from the above, this invention reduces the gravitational load on the erected unit 1 by setting an adjustable base A2 on its side and an adjustable base B3 on its bottom surface. Furthermore, by designing the structures of the adjustable bases A2 and B3, the erected unit 1 has adjustable space in three dimensions. The unit 1 slides in three dimensions using the adjustable bases A2 and B3 for load reduction, allowing for convenient and flexible adjustment manually after placement at the installation position without the need for a crane. This reduces hoisting work and significantly lessens the reliance on the expertise of on-site construction personnel. By placing multiple three-dimensional distributed load-reducing erected unit 1s one by one at their respective installation positions and then fastening them after adjustment, rapid assembly of ultra-large, high-precision erected unit 1s can be achieved. Compared with existing technologies, this invention has the following advantages:

[0089] 1. The adoption of a three-dimensional distributed load reduction erection structure can shorten the length of erection unit 1. Although the shortening of the length of erection unit 1 will lead to more assembly layers and thus larger assembly errors, these errors can be adjusted by the adjustable bases A2 and B3 on erection unit 1. Therefore, during the erection process, a small-tonnage crane can be used to lift the lighter erection unit 1, making the erection process more flexible and improving the erection efficiency. This solves the problems of large electronic equipment requiring the use of ultra-large cranes for hoisting, which result in high construction difficulty, high risk, high cost, and long time consumption.

[0090] 2. A three-dimensional distributed load reduction erection structure is adopted to provide a certain support load for the erection unit 1, reducing the adjustment force of the erection unit 1. By adjusting the number and type of springs in the adjustable base A2 and adjustable base B3, the dependence on the crane is reduced during manual adjustment, and the difficulty and number of manual adjustments are reduced, making the adjustment process more flexible and controllable. This solves the problems of needing a lot of manual adjustment and large cranes during the erection process.

[0091] 3. By reducing the difficulty and frequency of manual adjustments, construction time and costs are reduced, construction risks are further lowered, and personal safety during construction is further guaranteed.

[0092] 4. The erection unit 1 has adjustment functions in three directions: horizontal, vertical and normal, which can adapt to the problem of changes in the size of welded parts caused by the release of welding stress.

[0093] 5. The adoption of a three-dimensional distributed load reduction structure allows for the appropriate shortening of the length of key components, thus enabling better adaptation to both processing and transportation conditions.

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.
