Description

Technical Field

[0001] This utility model relates to the field of wind power automated testing technology, and more specifically, to a large base long-distance linear movement mechanism. Background Technology

[0002] In test benches for large equipment such as wind turbine transmission chains, there are many types of products being tested, and the installation positions of the test bench's moving device vary depending on the product being tested. However, the moving device includes a base, fuel station, transmission components, drive and loading motors, pipelines, wiring harnesses, etc.; the large base alone weighs hundreds of tons. When changing the product being tested, it is necessary to completely disassemble these components, hoist them to the required test position, reinstall them, adjust and align them, and then install the product being tested to meet the test requirements. However, the manual disassembly, installation, and adjustment of the moving device not only requires high technical skills from the operators, but also results in low overall disassembly, installation, and adjustment efficiency. In addition, the equipment hoisting and other operation methods pose significant safety hazards and frequent accidents. Therefore, we propose a long-distance linear moving mechanism for a large base to solve the above problems. Utility Model Content

[0003] The main purpose of this utility model is to provide a long-distance linear movement mechanism for a large base, which solves the problems that manual disassembly, installation and adjustment of the moving device not only requires high technical skills from the operators, but also results in low overall disassembly, installation and adjustment efficiency, as well as safety hazards and frequent accidents caused by equipment hoisting and other operation methods.

[0004] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0005] A large-scale base long-distance linear movement mechanism includes a base and a track, which are parallel vertically, with the track located on both sides of the lower end of the base. Side extension frames are mounted on both sides of the base, and fixed seats are installed in the middle of the interior of each side extension frame. A lead screw nut is threaded through the upper end of each fixed seat, and a ball screw is threaded through the interior of each lead screw nut. The ball screws are movably mounted inside the side extension frames. A front extension frame is mounted at the front end of the base, with a reducer installed at one end. A servo motor is mounted at the upper end of the front extension frame, and the output end of the servo motor is connected to the reducer. Couplings are movably mounted through both ends of the front extension frame, with the ends of the couplings close to each other connected to the reducer. Angle boxes are mounted at both ends of the front surface of the base, with the ends of the couplings furthest from each other connected to the ends of the angle boxes close to the front extension frame. The front end of each ball screw is connected to the rear end of the angle box.

[0006] Preferably, the front end of the side extension frame is respectively equipped with a bearing seat, the bearing seat is respectively installed with a bearing, the front end of the bearing seat is connected to the corner box, and the ball screw is installed through the inside of the bearing and connected to the corner box.

[0007] Preferably, locking plates are installed at the lower end of the fixing base, the side of the locking plate is in contact with the two side surfaces of the track, and a wedge block is installed through the interior of the fixing base and at the end near the base, and the lower end of the wedge block is engaged with the interior of the locking plate.

[0008] Preferably, a number of hydraulic cylinders are installed on the upper end of the fixed base, and the output ends of the hydraulic cylinders are connected to the upper end of the wedge block, while the lower end of the wedge block and the locking plate are located inside the upper end of the track.

[0009] Preferably, end bearing seats are respectively installed on the rear side of the side extension frame, and end bearings are respectively installed inside the end bearing seats. The rear end of the ball screw is respectively installed inside the end bearings.

[0010] Preferably, the base has several connecting seats installed inside, and each connecting seat has a lifting cylinder installed at its upper end. A roller bracket is movably installed inside the connecting seat. The upper end of the roller bracket is connected to the output end of the lifting cylinder. A roller is sleeved on the lower end of the roller bracket's rod and is movably installed inside the lower end of the base.

[0011] Compared with the prior art, the present invention has the following beneficial effects:

[0012] (1) In this utility model, when the base needs to be moved, the hydraulic cylinder pushes the wedge block downwards, allowing the wedge block to push the locking plate to lock on the track. At this time, the overall weight of the base is on the ball screw and the fixed seat, while the fixed seat is fixed by the locking plate and the track. Then, the servo motor can control the ball screw to rotate through the reducer, coupling, and angle box, so that the ball screw, together with the screw nut, drives the base to move. When the base cannot move a certain distance, the hydraulic cylinder can drive the wedge block to reset, causing the locking plate and the track to separate. Then, the lifting cylinder pushes the roller bracket and roller downwards, from... By lifting and moving the connecting seat and base and the fixed seat upwards, the rollers replace the fixed seat and locking plate to support the base, separating the weight of the fixed seat from the base. Then, the servo motor can control the ball screw to continue rotating through the reducer, coupling and angle box. At this time, the ball screw can control the fixed seat to move through the screw nut to adjust the position of the fixed seat. After the position of the fixed seat is adjusted, the lifting cylinder can slowly drive the roller to reset, allowing the base to move the fixed seat back onto the track. Then, the above steps are repeated to control the base to move to the designated assembly position for test piece installation and testing, which is simpler and faster. Attached Figure Description

[0025] like Figures 1 to 10 As shown in the figure, this utility model embodiment proposes a large base long-distance linear movement mechanism, including a base 1 and a track 18. The base 1 and the track 18 are parallel vertically, and the track 18 is located on both sides of the lower end of the base 1. Side extension frames 3 are respectively installed on both sides of the base 1. Fixed seats 13 are respectively installed in the middle of the interior of the side extension frames 3. Screw nuts 14 are respectively installed through the upper end of the interior of the fixed seats 13. Ball screws 10 are respectively installed through the threaded interior of the screw nuts 14. The ball screws 10 are respectively movably installed inside the interior of the side extension frames 3. A front extension frame 2 is installed at the front end of the base 1. A reducer 5 is installed at one end of the front extension frame 2. A servo motor 4 is installed at the upper end of the front extension frame 2. The output end of the servo motor 4 is connected to the reducer 5. A coupling 6 is movably installed through both ends of the front extension frame 2. The ends of the couplings 6 that are close to each other are connected to the reducer 5. Angle boxes 7 are installed at both ends of the front surface of the base 1. The ends of the couplings 6 that are far from each other are connected to the ends of the angle boxes 7 that are close to the front extension frame 2. The front end of the ball screw 10 is connected to the rear end of the angle box 7.

[0026] like Figure 5 , Figure 9 and Figure 10As shown, in another embodiment of this utility model, bearing seats 8 are respectively installed at the front end of the side extension frame 3, bearings 9 are respectively installed inside the bearing seats 8, the front end of the bearing seats 8 is connected to the corner box 7, the rod of the ball screw 10 is installed through the inside of the bearing 9 and connected to the corner box 7, locking plates 17 are respectively installed at the lower end of the fixed seat 13, the side of the locking plate 17 is in contact with the two side surfaces of the track 18, wedge blocks 15 are respectively installed through the inside of the fixed seat 13 and near the base 1, the lower end of the wedge blocks 15 is respectively engaged in the inside of the locking plate 17, and several hydraulic cylinders 16 are respectively installed at the upper end of the fixed seat 13, the output end of the hydraulic cylinders 16 is respectively connected to the wedge blocks 17. The upper end of 5 is connected, the lower end of the wedge block 15 and the locking piece 17 are located inside the upper end of the track 18, the rear side of the side extension frame 3 is respectively equipped with end bearing seats 12, the interior of the end bearing seats 12 is respectively equipped with end bearings 11, the rear end of the ball screw 10 is respectively installed inside the end bearings 11, the interior of the base 1 is equipped with several connecting seats 20, the upper end of the connecting seats 20 is respectively equipped with lifting cylinders 19, the interior of the connecting seats 20 is movably installed with roller brackets 22, the upper end of the roller brackets 22 is connected to the output end of the lifting cylinders 19, the lower end of the roller brackets 22 is sleeved with rollers 21, and the rollers 21 are movably installed inside the lower end of the base 1.

[0027] When the base 1 needs to be moved, the hydraulic cylinder 16 pushes the wedge block 15 downward, causing the wedge block 15 to push the locking plate 17 to lock on the track 18. At this time, the entire weight of the base 1 is located on the roller bracket 22 and the roller 21. At the same time, the fixed seat 13 is fixed by the locking plate 17 and the track 18. Then, the servo motor 4 can control the ball screw 10 to rotate through the reducer 5, coupling 6 and angle box 7, so that the ball screw 10, together with the screw nut 14, drives the base 1 to move. Then, when the screw nut 14 reaches the limit position and cannot meet the movement distance of the base 1, the hydraulic cylinder 16 can drive the wedge block 15 upward, so that the locking plate 17 and the track 18 are locked together. When track 18 is separated, base 1 is fixed in place by its own weight. Then, servo motor 4 can control ball screw 10 to reverse through reducer 5, coupling 6 and angle box 7. At this time, ball screw 10 can control fixed seat 13 to move in the opposite direction through screw nut 14, so that fixed seat 13 and screw nut 14 return to the end point. After the position of fixed seat 13 is adjusted, lifting cylinder 19 can slowly drive roller 21 to reset, so that base 1 drives fixed seat 13 to be on track 18 again. Then, the above steps are repeated to continue to control base 1 to move, so that base station 1 can be moved to the designated assembly position for test piece installation and testing, which is simpler and faster.

[0028] During the movement of the fixed seat 13, the guide column 19 limits the position of the fixed seat 13 during the movement to prevent the fixed seat 13 from shifting during the movement.

[0029] The end bearing 11 and the end bearing housing 12 are used to assist the ball screw 10 in rotating, and work with the bearing housing 8 and the bearing 9 to improve the stability of the ball screw 10 during rotation.

[0030] The working principle of this large-base long-distance linear movement mechanism:

[0031] In use, when the base 1 needs to be moved, the hydraulic cylinder 16 pushes the wedge block 15 downwards, causing the wedge block 15 to push the locking plate 17 to lock on the track 18. At this time, the entire weight of the base 1 is on the ball screw 10 and the fixed seat 13. Simultaneously, the fixed seat 13 is held in place by the locking plate 17 and the track 18. Then, the servo motor 4 controls the ball screw 10 to rotate via the reducer 5, coupling 6, and angle box 7, allowing the ball screw 10 to move in conjunction with the screw nut 14. When the screw nut 14 reaches its limit position and cannot satisfy the required movement distance of the base 1, the hydraulic cylinder 16 drives the wedge block 15 upwards, causing... The locking plate 17 and the track 18 are separated. At this time, the base 1 is fixed in place by its own weight. Then, the servo motor 4 can control the ball screw 10 to reverse through the reducer 5, coupling 6 and angle box 7. Then, the ball screw 10 can control the fixed seat 13 to move in the opposite direction through the screw nut 14, so that the fixed seat 13 and the screw nut 14 return to the end point. After the position of the fixed seat 13 is adjusted, the lifting cylinder 19 can slowly drive the roller 21 to reset, so that the base 1 drives the fixed seat 13 to be on the track 18 again. Then, the above steps are repeated to continue to control the base 1 to move, so that the base station 1 can be moved to the designated assembly position for test piece installation and testing.

Other variations or modifications can be made based on the above description. It is impossible to exhaustively list all the implementation methods here. Any obvious variations or modifications derived from the technical solutions of this utility model are still within the protection scope of this utility model.
