[0029] To address the numerous problems associated with flow tube installation in confined spaces, this application presents a flow tube installation platform. This platform achieves a certain degree of automation, is easy to operate, facilitates flow tube installation, offers high installation accuracy, requires minimal personnel, and can meet the needs for flow tube installation in confined spaces.

[0030] The following is a detailed description of an intake flow pipe multi-degree-of-freedom installation and adjustment device provided in an embodiment of this application, referring to... Figures 1 to 6 .

[0031] In one embodiment, refer to Figure 1 The multi-degree-of-freedom installation and adjustment device for the air intake flow pipe includes a base 5, a lifting support assembly 4 mounted on the base 5, and a lifting platform 2 mounted on the lifting support assembly 4. The air intake flow pipe is fixedly placed on the lifting platform 2. There are four lifting support assemblies 4, which are respectively located at the four corners of the base 5. An intermediate connecting assembly 7 is located in the middle of the base 5. The top of the intermediate connecting assembly 7 is fixed to the lifting platform 2. The lifting support assembly 4 and the intermediate connecting assembly 7 are controlled by an operating panel 8. By independently controlling the four lifting support assemblies 4, the vertical lifting, forward and backward tilting, left and right tilting, and diagonal tilting of the lifting platform 2 can be achieved.

[0032] In this embodiment, to facilitate the installation of flow tubes in confined spaces and under conditions where vehicles cannot use them, a flow tube installation platform for narrow spaces is proposed. The platform has four servo electric cylinders (lifting support components 4) evenly distributed around the circumference of φ2222mm at the center of the platform. By controlling the four servo electric cylinders to lift individually, in dual-axis and quad-axis modes, the platform can achieve vertical lifting (four-axis linkage), forward and backward pitching (two-axis linkage), left and right tilting (two-axis linkage), and diagonal tilting (single-axis movement), thus meeting the installation requirements of flow tubes of different models and under different installation environments.

[0033] In one embodiment, refer to Figure 2 The multi-degree-of-freedom installation and adjustment device for the intake flow pipe also includes two anti-rotation components 3. These two anti-rotation components 3 are respectively located on opposite sides of the base 5. The top of each anti-rotation component 3 is fixed to the lifting platform 2. Each anti-rotation component 3 includes a first support floating joint 3-1, a first piston rod 3-2, and a first cylinder assembly 3-3 connected in sequence. The first support floating joint 3-1 is connected to the lifting platform 2, and the first cylinder assembly 3-3 is connected to the base 5. The first cylinder assembly 3-3 includes a cylinder and a ball screw. During installation, two sets of anti-rotation components 3 are symmetrically installed with the center of the lifting platform 2 as the center of symmetry. This structure ensures that the lifting platform 2 retains its original motion capabilities (lifting, pitching, tilting) while limiting its rotational capability, making it more suitable for flow pipe installation environments in confined spaces.

[0034] In one embodiment, to ensure the intake flow pipe is securely fixed, the lifting platform 2 is equipped with triangular clamping seats 1 for fixing the intake flow pipe, which are located at the four corners of the lifting platform 2. The lifting platform 2 of the multi-degree-of-freedom installation and adjustment device for the intake flow pipe consists of a flat plate and four triangular clamping seats 1. This design ensures that flow pipes of different sizes can be fixed during installation. The operating panel 8 of the flow pipe installation platform is located in front of a servo electric cylinder on one side. This platform can be controlled by buttons and a remote control handle, further reducing the difficulty of use.

[0035] Preferably, the triangular clamping seats 1 are detachably installed on the lifting platform 2. The triangular clamping seats 1 are designed as right triangles, with the hypotenuses of the four triangular clamping seats 1 contacting the circumferential surface of the air intake flow pipe. That is, the triangular clamping seats 1 are installed in pairs at different positions to accommodate flow pipes of different sizes. Furthermore, due to gravity, the flow pipe is clamped, preventing slippage during lifting. Therefore, the movable design of the triangular clamping seats 1 can accommodate the installation of flow pipes of different sizes while ensuring the stability of the flow pipe during lifting.

[0036] In one embodiment, refer to Figure 3The lifting support assembly 4 includes a second support floating joint 4-1, a second piston rod 4-2, a second cylinder assembly 4-3, and a worm gear reducer assembly 4-6 connected sequentially from top to bottom. The second support floating joint 4-1 is connected to the lifting platform 2. The side of the second cylinder assembly 4-3 is also connected to a grating ruler assembly 4-4 for positioning. The worm gear reducer assembly 4-6 is also connected to a stepper motor 4-5. The second cylinder assembly 4-3 includes a cylinder and a ball screw. The worm gear reducer assembly 4-6 includes a worm gear reducer and a protective cover located on the outside.

[0037] Preferably, the design of the lifting support component 4 ensures the lifting capacity and accuracy of the lifting platform 2 while also having a self-locking capability.

[0038] In one embodiment, refer to Figure 4 The intermediate connecting assembly 7 includes, from top to bottom, an intermediate connecting floating joint 7-1, an intermediate connecting linear bearing 7-3, and a mounting mechanism 7-4. The intermediate connecting floating joint 7-1 and the intermediate connecting linear bearing 7-3 are connected by an intermediate connecting ball joint bearing 7-2, which is located inside the intermediate connecting floating joint 7-1. The top of the intermediate connecting floating joint 7-1 is connected to the lifting platform 2, and the bottom of the mounting mechanism 7-4 is connected to the base 5. The design of the intermediate connecting assembly 7 ensures that the center of the lifting platform 2 does not experience horizontal displacement, thus increasing the stability of the lifting platform 2.

[0039] In one embodiment, the base 5 has liftable support wheels 6 on its lower side. (See reference...) Figure 5 and Figure 6 The liftable support wheel 6 includes a rod and a wheel. The wheel is fitted onto the rod and can move up and down on the rod. When the wheel is raised, the rod provides support. Therefore, the liftable support wheel 6 can raise the wheel when the flow pipe installation platform does not need to be moved, so that each point of the flow pipe installation platform is effectively supported, thus preventing the platform from shifting during operation and causing safety accidents.

[0040] In one embodiment, the control panel 8 is equipped with a touch screen and a button area, and the use of the lifting platform 2 is controlled by the touch screen and the button area.

[0041] Furthermore, the device is also equipped with a remote control handle, which is communicatively connected to the lifting support assembly 4. The remote control handle allows for easy remote control of the flow pipe lifting platform. Its functions include single-cylinder operation, dual-cylinder linkage, four-cylinder linkage lifting control, and stopping; different functions are achieved through different buttons. Both the control panel 8 and the remote control handle allow for operation of the multi-degree-of-freedom installation and adjustment device for the intake flow pipe, reducing the difficulty of use.

[0042] In practical implementation, the base 5 is constructed with a square steel frame to ensure structural strength. Six sets of liftable support wheels 6 are installed below it, an operating platform 8 is mounted in front, and four lifting support components 4, one intermediate connecting component 7, and two anti-rotation components 3 are mounted above it. These seven devices support the lifting platform 2. Four triangular clamping seats 1 are installed above the lifting platform 2 to clamp the flow tubes. By controlling the lifting support components 4, the platform can be vertically raised, lowered forward and backward, tilted left and right, and tilted diagonally, thus meeting the installation requirements of flow tubes of different models and in different installation environments.

[0043] The multi-degree-of-freedom installation and adjustment device for the intake flow pipe provided by this invention has the following advantages:

[0044] a) The movable design of the triangular clamping seat 1 can adapt to the installation of flow tubes of different sizes, while ensuring the stability of the flow tube when it is raised or lowered.

[0045] b) The design of the anti-rotation component 3 limits the rotation capability of the lifting platform 2, making it more suitable for the installation environment of the flow pipe in narrow spaces;

[0046] c) The design of the lifting support assembly 4 ensures the lifting capacity and accuracy of the lifting platform 2 while also having a self-locking capability;

[0047] d) The design of the liftable support wheel 6 can effectively support the flow tube installation platform when it does not need to be moved, avoiding unnecessary displacement and safety hazards;

[0048] e) The design of the intermediate connecting component 7 ensures that the center of the lifting platform 2 does not undergo horizontal displacement, thus increasing the stability of the lifting platform 2.

[0049] f) Both the control panel 8 and the remote control handle can operate the flow tube installation platform, reducing the difficulty of use.

[0050] g) The flow tube installation platform is simple to operate and highly reliable, which can greatly reduce the difficulty of installing flow tubes in narrow spaces and reduce the number of personnel required for flow tube installation.

[0051] The above description is merely a specific embodiment of this application, but the scope of protection of this application is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this application should be included within the scope of protection of this application. Therefore, the scope of protection of this application should be determined by the scope of the claims.
