Description

Technical Field

[0001] This utility model belongs to the field of maintenance equipment technology and relates to a rotor maintenance vehicle. Background Technology

[0002] In modern industrial production, the efficient operation of mechanical equipment is crucial for ensuring production continuity and stability. As a core component of centrifugal equipment, the rotor's performance directly affects the overall efficiency of the equipment. For example, rotors in centrifugal compressors, steam turbines, multistage centrifugal pumps, and centrifugal fans inevitably experience wear, corrosion, or other malfunctions during long-term operation, thus requiring regular routine maintenance.

[0003] In current rotor maintenance, after the rotor is removed from the stator, it is usually transported using a simple support or wooden pallet. Because different rotors have different lengths and diameters, the simple support needs to be welded and reinforced each time. This results in a significant waste of manpower, resources, and effort on fabricating the rotor support frame during each maintenance process. This not only increases labor intensity, but also makes it difficult to guarantee measurement accuracy and safety with the temporarily fabricated support, and its bulky structure further complicates the accuracy guarantee.

[0004] Therefore, in order to ensure the safety and reliability of rotors during maintenance, placement, transportation and measurement, it is necessary to develop and design a rotor-specific maintenance trolley with a wide range of applications. Utility Model Content

[0020] In this document, terms such as "above," "below," "left," "right," "inner," and "outer" are established based on the positional relationships shown in the accompanying drawings. Depending on the drawings, these positional relationships may change; therefore, they should not be construed as absolute limitations on the scope of protection. Furthermore, relational terms such as "first" and "second" are merely used to distinguish one component from another with the same name, and do not necessarily require or imply any actual relationship or order between these components. In addition, in embodiments of this utility model, "above," "below," etc., include the stated number.

[0021] Reference Figure 1 and Figure 2 The rotor maintenance vehicle of this embodiment includes a base 1 and an adjustment seat 2. The bottom of the base 1 is provided with a movable wheel 11, and the two sides of the base 1 are provided with push-pull rods 12. The movable wheel 11 and the push-pull rods 12 can be used to facilitate the operator to move the rotor maintenance vehicle of this embodiment, thereby facilitating the convenient transportation of the rotor.

[0022] Specifically, there are eight casters 11, with four casters 11 located at the four corners of the bottom of the base 1. Placing the four casters 11 at the four corners of the bottom of the base 1 improves ease of movement. The other four casters 11 can be located on the four sides of the bottom of the base 1, or, as... Figure 1 For example, they are placed in pairs at the front and back edges. Here, "front and back" refers to the direction along... Figure 1 The direction shown is perpendicular to the paper.

[0023] More specifically, the base 1 has connecting plates on both sides, the push-pull rod 12 is connected to the connecting plates, and the push-pull rod 12 is inclined outward to facilitate the operator to push the rotor maintenance vehicle of this embodiment.

[0024] There are two adjusting seats 2, which are located on the top surface of the base 1. Each adjusting seat 2 includes a horizontal slide 21 that can move left and right along the top surface of the base 1. The distance between the two adjusting seats 2 can be changed using this horizontal slide 21, thereby accommodating rotors of different lengths and meeting the maintenance and transportation requirements of rotors of different lengths. In this embodiment, the left and right direction refers to... Figure 1 The example is parallel to the plane of the paper. Specifically, a track that mates with the horizontal slide 21 can be designed on the top surface of the base 1.

[0025] A support platform 22 is provided above the horizontal slide 21, and a height adjustment mechanism is provided above the support platform 22. The height adjustment mechanism can be used to adjust to different heights according to the diameter of different rotors to meet the support requirements of rotors with different diameters.

[0026] A rotor support mechanism is provided above the height adjustment mechanism. The rotor support mechanism includes a mounting base 27, and a fixed block 243 and a movable block 241 mounted on the mounting base 27. Both the fixed block 243 and the movable block 241 are equipped with rotor-supporting wheels 244. The rotor can be rotated using the wheels 244 to meet the requirements of runout measurement of rotor curvature. The movable block 241 is connected to a shaft diameter adjustment wheel 242. Driven by the shaft diameter adjustment wheel 242, the movable block 241 moves closer to or further away from the fixed block 243, thereby changing the distance between the fixed block 243 and the movable block 241 to accommodate different rotor shaft diameters.

[0027] Specifically, the moving block 241 and the fixed block 243 are provided with inclined surfaces that are arranged opposite to each other, and the rotating wheel 244 is provided on the inclined surface.

[0028] The rotor maintenance vehicle of this embodiment, through the moving wheels 11, push-pull rods 12, horizontal slides 21, height adjustment mechanism, moving blocks 241, fixed blocks 243 and rotating wheels, can meet the transportation convenience in rotor maintenance, and can simultaneously meet the maintenance and testing of rotors of different lengths, diameters and shaft diameters, realizing multi-purpose use of one vehicle, and improving labor efficiency and maintenance accuracy.

[0029] In this specific implementation, the height adjustment mechanism includes a height adjustment wheel 232, with an adjustment screw 233 connected to the top of the wheel 232. The adjustment screw 233 is connected to the mounting base 27. The rotation of the height adjustment wheel 232 drives the adjustment screw 233 to rise or fall, thereby changing the height of the mounting base 27 connected to it. This allows for changes in the height of the rotor support mechanism, meeting the support requirements of rotors with different diameters. Furthermore, the height adjustment method using the adjustment screw 233 is simple in structure and provides controllable height adjustment.

[0030] Specifically, the height adjustment mechanism also includes support columns 231 disposed around the height adjustment wheel 232, and an adjustment rod 234 connected to the top of the support columns 231. The adjustment rod 234 can rise and fall with the adjustment screw 233. By using the support columns 231 and the adjustment rod 234 disposed around the height adjustment wheel 232, the movement for height adjustment can be assisted, thereby improving the reliability of the entire device.

[0031] Along the front-to-back direction, the top of the adjusting rod 234 on the same side is connected to a supporting channel steel 25. A connecting seat 26 is provided between the two supporting channel steels 25, and a mounting seat 27 is located on the connecting seat 26. Along the left-to-right direction, the connecting seat 26 is located on both sides of the mounting seat 27. Utilizing the structure of the supporting channel steel 25 and the connecting seat 26, a frame structure can be used to support the mounting seat 27, saving materials and reducing costs while meeting support requirements. At the same time, placing the connecting seat 26 on the left and right sides of the mounting seat 27 allows for horizontal restriction of the mounting seat 27, improving the accuracy of this rotor maintenance vehicle.

[0032] Where the embodiments do not contradict each other, at least some of the technical solutions in each embodiment can be recombine to form the essential technical solution of this utility model. Of course, the embodiments can also reference or include each other. Furthermore, it should be noted that adaptive adjustments and modifications made by those skilled in the art when recombinating the technical means described in the embodiments will also fall within the protection scope of this utility model.

[0033] The technical principles of this utility model have been described above in conjunction with specific embodiments. However, it should be noted that these descriptions are merely for explaining the principles of this utility model and should not be construed as limiting the scope of protection of this utility model in any way. Based on this explanation, other specific embodiments or equivalent substitutions of this utility model that can be conceived by those skilled in the art without creative effort will all fall within the scope of protection of this utility model.
