Abstract
Description
Technical Field
[0001] This utility model relates to the field of turbine blade manufacturing technology, and in particular to a support device for turbine blade manufacturing. Background Technology
[0002] The turbine blades are key components of a steam turbine, and among the most delicate and important. They withstand extremely harsh conditions, including high temperature, high pressure, immense centrifugal force, steam force, steam excitation force, corrosion and vibration, and the erosion from water droplets in the wet steam zone. Their aerodynamic performance, machining geometry, surface roughness, installation clearance, operating conditions, and scaling all affect the turbine's efficiency and output; their structural design, vibration intensity, and operating mode have a decisive impact on the unit's safety and reliability.
[0003] During the placement and transportation of steam turbine blades, workers usually stack multiple blades together. However, due to the shaking of the vehicle body during transportation, the blades are prone to collisions, which can damage them. Therefore, there is an urgent need for a support device for the production of steam turbine blades. Utility Model Content
[0004] The purpose of this invention is to address the shortcomings of existing technologies by providing a support device for the production of steam turbine blades, thereby solving the problems mentioned in the background art.
[0005] A bearing device for producing steam turbine blades includes a movable frame and a limiting mechanism installed on the movable frame. The limiting mechanism includes an upper limiting component and a lower limiting component. The upper limiting component includes a cylinder, a limiting plate, a baffle, a stop block, and a slider. The cylinders are installed in two sets at an angle on both sides of the upper end face of the movable frame. The slider is fixed at the output end of the cylinder. The limiting plate and the slider are slidably connected. The baffle is installed on the bearing plate in the middle of the movable frame. The stop blocks are distributed in pairs on both sides of the placement opening of the bearing plate.
[0006] The lower limit assembly includes a support plate, a rubber pad, a nut, a stud, and rubber blocks. The four corners of the support plate are supported by the nut and the stud. The rubber pad is fixed to the support plate. There are multiple rubber blocks, which are evenly arranged on the rubber pad.
[0007] By adopting the above technical solution, it is convenient to place the blades, avoid collisions between blades that could cause damage, and facilitate the transfer of blades.
[0008] The placement openings are multiple and evenly arranged on the support plate, and the protrusions between the placement openings are adapted to the connection ports.
[0009] The above technical solution facilitates the placement of the blades.
[0010] One side of the limiting plate has a downward-facing sliding groove, and the slider slides in the sliding groove.
[0011] By adopting the above technical solution, space is left for placing the blades.
[0012] The rubber block is also set at an angle, and its angle of inclination is the same as the angle of inclination of the placement opening and the angle of inclination of the cylinder.
[0013] By adopting the above technical solution, the lower end of the blade is restricted.
[0014] The blocks are arranged in a right-angled trapezoidal structure, and the blocks in the same group are arranged with their inclined surfaces facing each other.
[0015] By adopting the above technical solution, the upper part of the blade is restricted.
[0016] The beneficial effects of this utility model of a bearing device for turbine blade production are:
[0017] When placing the blades, detach the limiting plate from the slider and place the blades one by one at the placement port position. Then, place the limiting plate back on the slider at the cylinder output end and drive the cylinder to pull the limiting plate to move so that the connecting port fits onto the protrusion of the support plate until the limiting plate is attached to the other end of the upper part of the blade. Adjust the height of the nut on the stud to adjust the height of the support plate until the bottom of the blade abuts against the rubber pad. Because there is also a rubber block on the rubber pad, it further restricts the shaking of the lower end of the blade and prevents collisions. The blades are also moved to the designated position by the rollers at the bottom of the moving frame. This device facilitates the placement of blades, avoids collisions between blades that may cause damage, and facilitates the transfer of blades. Attached Figure Description

[0021] The preferred embodiments of the present invention will now be described in detail with reference to the accompanying drawings, so that the advantages and features of the present invention can be more easily understood by those skilled in the art, thereby providing a clearer and more definite definition of the scope of protection of the present invention.
[0022] Reference Figure 1-2 A bearing device for producing steam turbine blades includes a movable frame 1 and a limiting mechanism installed on the movable frame 1. The limiting mechanism includes an upper limiting component and a lower limiting component. The upper limiting component includes a cylinder 2, a limiting plate 3, a baffle 4, a stop block 5, and a slider 6. The cylinder 2 is installed in two sets at an angle on both sides of the upper end face of the movable frame 1. The slider 6 is fixed at the output end of the cylinder 2. The limiting plate 3 and the slider 6 are slidably connected. The baffle 4 is installed on the bearing plate 101 in the middle of the movable frame 1. The stop blocks 5 are distributed in pairs on both sides of the placement opening 1011 of the bearing plate 101.
[0023] The lower limit assembly includes a support plate 7, a rubber pad 8, a nut 9, a stud 10, and rubber blocks 11. The four corners of the support plate 7 are supported by the nut 9 and the stud 10. The rubber pad 8 is fixed on the support plate 7. There are multiple rubber blocks 11, which are evenly arranged on the rubber pad 8.
[0024] When placing the blade 12, the limiting plate 3 can be lifted upwards and removed from the slider 6 at the output end of the cylinder 2. Then, the blades 12 can be placed one by one at the placement port 1011, and one end of the upper part of the blade 12 can be placed against the side of the baffle 4. The left and right sides are limited by the stop block 5. After placement, the limiting plate 3 can be placed back on the slider 6 at the output end of the cylinder 2, and the cylinder 2 can be driven to pull the limiting plate 3 to move, so that the connecting port 301 is fitted onto the protrusion of the bearing plate 101 until the limiting plate 3 is attached to the other end of the upper part of the blade 12, thus limiting the upper part of the blade 12.
[0025] At this time, the height of the nut 9 on the stud 10 can be adjusted to adjust the height of the support plate 7 until the bottom of the blade 12 is in contact with the rubber pad 8. Since the rubber pad 8 is also provided with a rubber block 11, it further restricts the lower end of the blade 12 from shaking and causing a collision.
[0026] After the blade 12 is positioned, it can be moved to the designated position by the rollers at the bottom of the movable frame 1.
[0027] Multiple placement openings 1011 are evenly arranged on the support plate 101. The protrusions between the placement openings 1011 are adapted to the connection openings 301. The placement openings 1011 are set in an inclined state to facilitate the placement of the blade 12 by the staff. The length of the placement opening 1011 is greater than the width of the blade 12 to ensure that the other end of the blade 12 is subsequently limited by the limiting plate 3.
[0028] One side of the limiting plate 3 has a downward-facing sliding groove, and the slider 6 slides in the sliding groove. According to the above configuration, when placing and removing the blade 12, the limiting plate 3 can be lifted upward from the slider 6 and removed, so as to avoid the limiting plate 3 affecting the placement and removal of the blade 12.
[0029] The rubber block 11 is also set in an inclined state, and its inclination angle is the same as the inclination angle of the placement port 1011 and the inclination angle of the cylinder 2. After the blade 12 is placed on the support plate 101, the height of the rubber pad 8 can be adjusted. The rubber pad 8 can prevent the bottom of the blade 12 from making hard contact with the support plate 7, and the rubber pad 8 can contact the bottom of the blade 12, which can help reduce the shaking of the lower end of the blade 12. The rubber block 11 can effectively prevent the lower end of the blade 12 from colliding due to shaking.
[0030] The stop block 5 is set in a right-angled trapezoidal structure, and the same set of stop blocks 5 are set with inclined surfaces facing each other; after the blade 12 is placed on the bearing plate 101, one end is restricted by the stop plate 4 and the stop block 5. After the limiting plate 3 restricts the other end of the blade 12, the blade 12 can have a stable state and be stably restricted.
[0031] The embodiments described above are merely examples of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these modifications and improvements all fall within the protection scope of this utility model.
