Description

Technical Field

[0001] The invention relates to the technical field of building construction, and in particular to auxiliary equipment for assembling special-shaped structural parts. Background Art

[0002] With the development and renewal of cities, steel structure buildings have gradually become an important structural form and an indispensable type of modern building structure. As a type of building structure, steel structure is different from reinforced concrete structure. Steel structure buildings are made of steel as the main material. They have the characteristics of overall lightness, saving foundation, less materials, low cost, short construction period, large span, safety and reliability, beautiful appearance, and stable structure.

[0003] As the current demand for building appearance and functions becomes more and more diversified, the requirements for steel structures are also getting higher and higher. The steel structure form of ordinary space can no longer meet the use needs, so more structural forms are needed to meet the needs. The installation of steel structure components in special-shaped spaces has always been a construction difficulty. The installation form is usually factory installation or on-site installation. These two installation methods have their own advantages and disadvantages.

[0004] Although factory assembly is effective, fast and of high quality, it has high requirements for transportation and high component transportation costs. This method is suitable for projects with smaller scale or better transportation conditions, but for large or complex special-shaped structural parts, there may be many challenges during transportation, such as road restrictions, transportation equipment restrictions, etc. These factors will greatly increase the cost and risk of the project.

[0005] On-site assembly has lower requirements for transportation, but the assembly conditions are limited, the construction quality is not high, and the efficiency is low. On the construction site, due to the limitations of space, equipment and human resources, the precise positioning and installation of special-shaped structural parts become very difficult. In addition, the uncertainty of the on-site environment, such as weather changes and terrain conditions, will also have a negative impact on the construction quality and efficiency. Although this method solves the transportation problem to a certain extent, it brings new construction problems.

[0006] These problems are a great constraint on the development of steel structure buildings. The difficulty of assembling special-shaped structural parts directly affects the overall quality and construction period of the building, and also increases the construction cost; this is a great constraint on the development of steel structure buildings.

[0007] Therefore, in order to solve the above problems, there is a need for an auxiliary equipment for assembling special-shaped structural parts, which can assemble steel structural members of special-shaped spaces with higher construction quality and efficiency at construction sites with limited assembly conditions.

[0033] Figure 1It is a structural schematic diagram of the present invention. As shown in the figure, the auxiliary equipment for assembling the special-shaped structural member 002 in this embodiment includes a support body 001 and a structural member 002 assembled on the support body 001; the assembly method of the support body 001 and the structural member 002 includes welding, bolt connection or riveting, etc.; the support body 001 of this scheme is arranged along the height direction, and the structural member 002 includes a plurality of structural members arranged circumferentially on the support body 001. The assembly method of the support body 001 and the structural member 002 is welding. Before welding, the auxiliary equipment is used to position the corresponding structural member 002 to the preset position of the support body 001.

[0034] The auxiliary equipment includes a support assembly, which includes a support seat 1 and a fork arm 3 arranged on the support seat 1 through a rotating pair Ⅰ2. The rotating pair Ⅰ2 can be a hinge, a universal joint or a ball joint, etc. The fork arm 3 has a clamp that supports the structural member 002. The clamp can be a mechanical clamp, an electromagnetic suction cup or a support-type limit groove. The mechanical clamp can be further designed as a V-shaped clamp, a C-shaped clamp or a parallel clamp to adapt to the structural member 002 of different cross-sectional shapes, which will not be repeated here; the support seat 1 is driven to adjust to a preset height so that the preset structural member 002 is supported at a set position by the clamp of the fork arm 3. The height adjustment of the support seat 1 can be achieved by a hydraulic cylinder, a screw nut mechanism or a gear rack mechanism. This solution can adapt to the complex assembly position requirements of the special-shaped structural member 002 in space by combining an adjustable height support assembly with a multi-degree-of-freedom fork arm 3 structure. It can accurately locate and support the special-shaped structural part 002, and its structure is simple and easy to operate, which solves the problems of limited on-site assembly conditions and low construction quality. It has the advantages of improving the assembly efficiency of the special-shaped structural part 002, improving assembly quality, reducing construction costs and improving construction safety. Among them, the height-adjustable support seat 1 solves the assembly requirements of the structural part 002 at different elevations, and the fork arm 3 structure with the rotating pair Ⅰ2 allows the clamp to flexibly adjust its posture in the workspace. When using it, it is only necessary to set the structural part 002 on the clamp. Compared with the traditional fixed support tooling, this equipment significantly improves the positioning accuracy and assembly efficiency of the special-shaped structural part 002 in a restricted construction environment, and effectively solves the quality problems caused by limited on-site assembly conditions. In specific implementation, the drive system of the support seat 1 can adopt closed-loop control to ensure positioning accuracy, and the rotating pair Ⅰ2 of the fork arm 3 can be equipped with a damper to maintain a stable posture; it is set according to actual conditions and will not be repeated here.

[0035] In this embodiment, the clamping jaw of the fork arm 3 is C-shaped, and the middle part of the C-shaped is connected to the rotating pair Ⅰ2 through a support rod. When in use, the structural member 002 is limitedly supported through the C-shaped opening, and the rotating pair Ⅰ2 includes a universal coupling connecting the fork arm 3 and the support seat 1. The universal coupling is selected from any of the existing technologies, one end of the universal coupling is fixed to the fork arm 3, and the other end is fixed to the support rod connecting the clamping jaw. By using the universal coupling as the core component of the rotating pair Ⅰ2, the technical problem of multi-angle adjustment during the assembly process of the special-shaped structural member 002 is effectively solved. Specifically, the universal coupling allows the fork arm 3 to rotate freely in multiple directions, so as to adapt to the assembly requirements of the special-shaped structural member 002 at different angles and positions. Compared with the traditional single rotating pair, the universal coupling provides a greater degree of adjustment freedom, so that the clamping jaw can more accurately support the structural member 002 at the set position. This design significantly improves the adaptability and operational flexibility of the assembly equipment, and is particularly suitable for the assembly of special-shaped structural members 002 with complex spatial angles.

[0036] In this embodiment, the structural member 002 includes several members arranged around the circumference of the support body 001, and the support assembly includes several groups arranged in a one-to-one correspondence with the structural member 002; the auxiliary equipment also includes a connecting member, which connects the corresponding support seats 1 in two adjacent groups of support assemblies. By setting up multiple groups of support assemblies corresponding to the structural member 002 and connecting adjacent support seats 1 with connecting members, it is possible to achieve synchronous positioning and support of multiple structural members 002; compared with the prior art, this solution improves assembly efficiency and ensures the relative position accuracy between multiple structural members 002, and is particularly suitable for occasions where multiple surrounding structural members 002 need to be assembled at the same time. The connecting member can be a rod-shaped structure, a telescopic rod 4 structure, or other structures with a connection function, etc., which will not be repeated here.

[0037] In this embodiment, the connecting member includes a telescopic rod 4 with adjustable length and a fastener 5 arranged on the telescopic rod 4 through a rotating pair II. The adjustable length design of the connecting member can adapt to the arrangement requirements of the support seat 1 with different spacings. The length adjustment of the telescopic rod 4 can be achieved by means of a threaded pair, a hydraulic cylinder or an electric push rod to adapt to the installation positions with different spacings; the telescopic rod 4 is detachably connected to the support seat 1 through a fastener 5, and the fastener 5 can be a structure such as a clamp, a limit sleeve or a clamping claw, which is suitable for satisfying the detachable limit function. It will not be repeated here. The detachable function of the telescopic rod 4 on the support seat 1 makes this solution have the advantage of strong versatility; the fastener 5 includes two respectively arranged at both ends of the telescopic rod 4; as a preferred embodiment, the connection surface of the fastener 5 and the structural member 002 can be provided with anti-slip textures or rubber pads to enhance friction and improve the positioning and support effect of the structural member 002, which will not be repeated here.

[0038] In this embodiment, a pull-out telescopic rod 4 with damping in the prior art is adopted, and the fastener 5 adopts a quick-release clamp structure in the prior art to ensure the connection stability and realize the rapid connection and separation of the connecting rod and the structural member 002; the rotating pair II adopts a hinge structure so that the fastener 5 can rotate around the axis hinged to the telescopic rod 4. More specifically, the rotating pair II includes an intermediate shaft 6 that hinges the telescopic rod 4 and the fastener 5, that is, the telescopic rod 4, the intermediate shaft 6 and the clamp together constitute the rotating pair II, and the axes of the intermediate shaft 6 corresponding to the two fasteners 5 set on the same telescopic rod 4 are parallel to ensure the stability of the connecting member during the adjustment process, and the connecting member can not only play the function of connecting but also the function of limiting the support seat 1, thereby ensuring that the structural member 002 is stably supported at the set position. By combining the telescopic rod 4 with adjustable length and the rotatable fastener 5, the flexible adjustment of the distance between adjacent support components and the angle adaptation are realized. In the specific working process, the length adjustment function of the telescopic rod 4 can adapt to the installation requirements of the structural parts 002 with different spacings. The structure of the rotating pair II allows the fastener 5 to automatically adjust the angle according to the position of the structural part 002. The fasteners 5 set at both ends of the telescopic rod 4 ensure the uniform distribution of the connection force. Compared with the fixed-length connecting rod, this design significantly improves the equipment's adaptability to different specifications of special-shaped structural parts 002, and solves the connection difficulty problem caused by component size deviation during on-site assembly. At the same time, the detachable connection method facilitates quick disassembly and maintenance, reducing the complexity of construction.

[0039] In this embodiment, the auxiliary equipment also includes a lifting assembly, which includes a base set at a preset position and a slide driven to lift on the base, and the support seat 1 is set on the slide; the lifting assembly can be a hydraulic cylinder structure, a cylinder structure, a jack structure or a lifting platform structure, etc., which can meet the preset lifting requirements, and will not be repeated here; the lifting assembly includes several groups arranged in a one-to-one correspondence with the support seat 1. By setting up multiple groups of independently controlled lifting assemblies, the height position of each support seat 1 can be accurately adjusted to adapt to the complex assembly requirements of the special-shaped structural member 002 in space. Compared with the fixed height support method, this design solves the problem of assembly difficulties caused by the difference in spatial position of the special-shaped structural member 002, and realizes rapid positioning through the height adjustable mechanism, thereby improving assembly accuracy and efficiency. The modular design of the lifting assembly facilitates the increase or decrease of the number according to actual needs, and enhances the adaptability of the equipment.

[0040] In this embodiment, the auxiliary equipment also includes a hydraulic pump station 003, and the hydraulic pump station 003 is selected from any of the existing technologies. The lifting assembly includes a hydraulic cylinder 7 connected to the hydraulic pump station 003. More specifically, the hydraulic cylinder 7 is connected to the hydraulic pump station 003 through an oil pipe. The hydraulic pump station 003 serves as a power source to provide hydraulic oil to the hydraulic cylinder 7. The lifting and lowering movement of the piston is achieved by controlling the flow direction and flow rate of the hydraulic oil. The hydraulic drive mode has the characteristics of large bearing capacity and high positioning accuracy. A balance valve is provided on the hydraulic cylinder 7 to ensure that the supported heavy object will not slide down in the event of an accident such as an external oil pipe burst, which is safer and effectively solves the stability problem of the hydraulic cylinder 7 caused by load changes or system pressure fluctuations during the assembly of the special-shaped structural member 002. The balance valve is selected from any of the existing technologies. Compared with the existing technology, this solution significantly improves the safety and reliability of the assembly process, and is particularly suitable for working conditions with complex construction site conditions and frequent load changes; the setting of the balance valve also reduces the operator's need for manual intervention in the hydraulic system and improves assembly efficiency. It should be understood that the hydraulic pump station 003 has a control panel and is electrically connected to each group of hydraulic cylinders 7. Each group of hydraulic cylinders 7 can be independently controlled, and synchronous lifting or individual adjustment can be achieved through the PLC system to meet the assembly requirements of different height positions; the hydraulic pump station 003 can be equipped with a pressure regulating valve and a flow control valve to adapt to different load and speed requirements. The hydraulic system can be equipped with a pressure sensor and a position sensor to achieve closed-loop control. It is selected according to the actual situation and will not be repeated here.

[0041] In this embodiment, the cylinder body of the hydraulic cylinder 7 is set at a preset position as a base, the piston of the hydraulic cylinder 7 is connected to the support seat 1 as a slide seat, and the piston and the support seat 1 are assembled by flange connection, so as to realize the rapid disassembly and maintenance of the piston of the hydraulic cylinder 7 and the support seat 1. Compared with the traditional welding or threaded direct connection method, the flange connection has higher connection rigidity and positioning accuracy, can effectively transmit the push and pull force of the hydraulic cylinder 7 and bear the eccentric load moment during the assembly process. The modular design of the flange connection is convenient for adjusting the angle of the support seat 1 on site, and at the same time reduces the difficulty of disassembly during the maintenance of the hydraulic cylinder 7. In the specific implementation, the flange connection structure can select flanges and bolt groups of different specifications according to the actual load requirements, and has good engineering adaptability, which will not be repeated here. This technical solution realizes the lifting and lowering adjustment of the support assembly through hydraulic drive, and has greater output force and better impact resistance than mechanical or electric drive methods. The hydraulic system can smoothly bear the weight of the special-shaped structural member 002 and maintain a stable supporting force during the assembly process. Since the cylinder body of the hydraulic cylinder 7 is directly used as the base, the structure is simplified, the intermediate transmission link is reduced, and the rigidity and response speed of the system are improved. The centralized oil supply of the hydraulic pump station 003 facilitates the synchronous control of multiple lifting components, ensuring coordinated movement of each support point. This design is particularly suitable for the precise assembly of heavy special-shaped structural parts 002 at construction sites with limited space.

[0042] In this embodiment, the connecting piece is assembled at one end of the cylinder body close to the piston, that is, the connecting piece is located in the upper area of ​​the cylinder body of the hydraulic cylinder 7, which not only ensures the linkage stability between the supporting components, but also avoids motion interference; secondly, this arrangement makes the connecting piece in a relatively fixed position, which is convenient for quick disassembly and assembly on site; finally, by setting the connection point at the upper part of the cylinder body, the lateral load transmitted by the supporting component can be effectively shared, and the stability of the overall structure can be improved. Compared with the solution of setting the connecting piece on the piston rod, this design is more conducive to maintaining the positioning accuracy of the connecting piece, while reducing the vibration effect during the movement of the hydraulic cylinder 7.

[0043] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the present invention rather than to limit it. Although the present invention has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical solution of the present invention can be modified or replaced by equivalents without departing from the purpose and scope of the technical solution of the present invention, which should be included in the scope of the claims of the present invention.
