Description
Technical Field
[0001] This utility model belongs to the field of automation equipment technology, specifically relating to an RGV shuttle compensation track mechanism, used to connect the daughter car track on the mother car with the workstation track on the connecting workstation. Background Technology
[0002] During transformer manufacturing, the transformer coils need to be transferred between different workstations during the casting and curing process. This process typically requires the use of an RGV shuttle. The RGV shuttle employs a mother-daughter structure, with the mother car equipped with daughter car tracks and compensating tracks. The daughter car slides along these tracks, and the transformer coils are placed on the daughter car. When transferring coil materials between the mother car and daughter car, the daughter car tracks on the mother car must precisely align with the workstation tracks within the connecting workstation or specialized equipment to ensure the daughter car can move horizontally from the mother car to the workstation along the tracks. When the distance between the daughter car tracks and the connecting workstation or specialized equipment is significant, the compensating tracks on the mother car are used to connect the daughter car tracks to the workstation tracks.
[0003] The existing compensation track on the mother car has a large gap at the connection point with the daughter car track. When the daughter car passes through this connection point, it will get stuck and the daughter car wheels will be subjected to a strong impact. This not only affects the smooth operation of the daughter car, but also accelerates the wear of the daughter car wheels and reduces the service life of the daughter car. The existing compensation track does not have a track gauge adjustment function, and the installation accuracy requirements are extremely high. The installation process of the compensation track is complicated and it is difficult to guarantee the installation quality. Once the compensation track is installed incorrectly, it will affect the normal operation of the daughter car and increase the installation and maintenance costs. Summary of the Invention
[0004] To solve the above-mentioned technical problems, this utility model provides an RGV shuttle compensation track mechanism, including a compensation track, a first compensation track seat, and a second compensation track seat. A pair of first compensation track seats are fixedly installed above one end of the mother car platform, and the second compensation track seat is rotatably installed above the first compensation track seat. The second compensation track seat has an elongated hole 2. The end of the compensation track is fixedly installed on the second compensation track seat by a bolt 2 passing through the elongated hole 2 and a nut 2. The lower part of the child car track has an elongated hole 1. The child car track is fixedly installed on the mother car platform by a bolt 1 passing through the elongated hole 1 and a nut 1.

[0005] Preferably, a sensing mechanism is provided on the outer side of the first compensation track seat at one end. The sensing mechanism includes a detection sensor base, a detection sensor, and a detection reference piece. The lower end of the detection sensor base is fixedly installed on the mother car platform.

The detection reference piece is fixedly installed on the outer side of the first compensation track seat and can rotate synchronously with the second compensation track seat.
[0006] Preferably, the first compensation track seat includes a pair of parallel blocks, the outer sides of the pair of blocks are fixedly mounted on the upper part of the mounting plate of the U-shaped structure, and the lower part of the mounting plate is fixedly mounted on the outer side of the mother car platform.
[0007] Preferably, the two ends of the drive shaft are rotatably connected to a pair of first bearings in the first compensation track seat, and the drive shaft is rotatably connected to the first compensation track seat through the first bearings.
[0008] Preferably, an adjustment motor is fixedly installed on the outer side of the first compensation track seat at the other end, and the output shaft of the adjustment motor is connected to the drive shaft through a chain drive assembly.

[0012] Preferably, compression bolts are respectively provided on the outer side of a pair of second compensation track seats.
[0013] The beneficial effects of this utility model are:
[0014] In this invention, the first and second compensating track seats are arranged in a stepped configuration, which raises the rotation center of the compensating track. This reduces the gap between the compensating track and the trolley track when the track rotates to a horizontal position, allowing the trolley to smoothly transition over track joints, avoiding jamming and impact. This improves the stability and reliability of the trolley's operation and extends the service life of the trolley and related components. The second compensating track seat connects to the compensating track via a second elongated hole, and the mother car platform connects to the trolley track via a first elongated hole. This allows for adjustment of the distance between the compensating track and the trolley track, enabling the compensating track to adapt to different workstation tracks. Attached Figure Description

[0023] The technical solution of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are some embodiments of this utility model, but not all embodiments.
[0024] RGV shuttles consist of forks, daughter cars, and mother cars, such as Figure 1-6 As shown, the mother car includes a mother car platform 11 and a mother car traveling mechanism, which enables the mother car platform 11 to move between connecting workstations or special equipment. A pair of parallel daughter car tracks 12 are bolted to the mother car platform 11. Two rows of daughter car rollers are installed at the bottom of the daughter car, and these rollers are placed within the pair of daughter car tracks 12. The mother car pushes and pulls the daughter car with its forks, causing the daughter car rollers to roll within the daughter car tracks 12, thus enabling the daughter car to move horizontally. An elongated hole is provided at the connection between the daughter car track 12 and the mother car platform 11, allowing for quick adjustment of the spacing between the pair of daughter car tracks 12 according to the requirements of different workstations.
[0025] This utility model embodiment provides an RGV shuttle compensation track mechanism, including a compensation track 1, a mounting plate 7, a first compensation track seat 9, and a second compensation track seat 3. In this embodiment, two first compensation track seats 9 are symmetrically arranged. Each first compensation track seat 9 includes a pair of L-shaped blocks arranged parallel to each other. The outer end faces of the pair of L-shaped blocks are fixed to the upper part of the mounting plate 7 by bolts. The mounting plate 7 is a U-shaped steel plate, and the lower part of the mounting plate 7 is fixed to the outer surface of the mother car platform 11 by bolts. A drive shaft 8 is rotatably arranged between the pair of first compensation track seats 9. The two ends of the drive shaft 8 pass through the first bearings in the two first compensation track seats 9, and the drive shaft 8 is rotatably connected to the first compensation track seats 9 through the first bearings.
[0026] A second compensation track seat 3 is rotatably mounted above the first compensation track seat 9. The second compensation track seat 3 is rotatably connected to the first compensation track seat 9 via a connecting shaft. The second compensation track seat 3 is located between a pair of L-shaped blocks of the first compensation track seat 9. The two ends of the connecting shaft pass through the second bearings in the two L-shaped blocks respectively. The connecting shaft is rotatably connected to the pair of L-shaped blocks via the second bearings. The second compensation track seat 3 is fixedly mounted on the connecting shaft. An adjustment motor 5 is fixedly mounted on the outer side of the first compensation track seat 9 on the left side. The output shaft of the adjustment motor 5 is connected to the drive shaft 8 via a chain drive assembly 6. Starting the adjustment motor 5 can control the rotation of the drive shaft 8. The second compensation track seat 3 includes a left side plate, a right side plate, and a rear side plate that are fixedly connected as one piece by bolts. The rear side plate is located on the outer side. The left side plate and the right side plate are arranged parallel to each other on both sides of the rear side plate. The left side plate and the right side plate are rectangular plates with chamfered corners at the top. The chamfered corners of the left side plate and the right side plate are located on the inner side.
[0027] The connecting shaft between the second compensating track seat 3 and the first compensating track seat 9 is connected to the drive shaft 8 via a gear transmission assembly 4 on the outside of each first compensating track seat 9. When the adjusting motor 5 controls the drive shaft 8 to rotate, the rotating drive shaft 8 can control the rotation of the second compensating track seat 3 via the gear transmission assembly 4. The driven wheel in the gear transmission assembly 4 is an incomplete gear. When the compensating track 1 rotates to the horizontal position, the incomplete gear can avoid obstructing the movement of the trolley along the track.
[0028] The compensation rail 1 is bolted to the second compensation rail seat 3. The structure of the compensation rail 1 is the same as that of the trolley rail 12. The drive shaft 8 passes through the end of the compensation rail 1, and the end of the compensation rail 1 is bolted to the inner surface of the rear side plate of the second compensation rail seat 3. The compensation rail 1 can rotate with the second compensation rail seat 3. A set of elongated holes 2 are provided on the rear side plate of the second compensation rail seat 3 at the connection with the compensation rail 1. The spacing between the pair of compensation rails 1 can be easily adjusted by installing bolts 2 in the elongated holes 2. The outer sides of the pair of second compensation rail seats 3 are respectively provided with clamping bolts 2, which can serve as a reference when adjusting the spacing between the two compensation rails 1. When the compensation rail 1 is in use (horizontal direction), it is adjacent to the trolley rail 12, forming a compensation transition structure for the trolley to move smoothly to the work station rail. When the compensation rail 1 is not in use (vertical direction), there is a certain gap between the compensation rail 1 and the end of the trolley rail 12. This gap is a redundant distance reserved for the rotation of the compensation rail 1.
[0029] A sensing mechanism 10 is provided on the right side of the first compensation track seat 9 at the right end. The sensing mechanism 10 is used to confirm whether the compensation track 1 is in a vertical or horizontal state. The sensing mechanism 10 includes a detection sensor base 13, a detection sensor 14, and a detection reference component 15. The lower end of the detection sensor base 13 is fixedly installed on the mother car platform 11 by bolts. The upper part of the detection sensor base 13 is a fan-shaped plate with two downward-curving arc-shaped grooves. The detection sensors 14 are fixedly installed at both ends of the arc-shaped grooves. A detection reference component 15 is provided on the right side of the first compensation track seat 9 and is fixedly connected to the right end of the connecting shaft. The detection reference component 15 is a thin plate with an L-shaped structure. The detection reference component 15 can rotate with the compensation track 1. When the compensation track 1 is in use (horizontal direction), the position of the detection reference component 15 corresponds to a set of detection sensors 14 that are away from the workstation track. The detection sensor 14 is used to determine the position of the detection reference 15 and to determine the state of the compensation track 1 based on the position of the detection reference 15: when a set of detection sensors 14 close to the workstation track scans the detection reference 15, the compensation track 1 is in a vertical state; when a set of detection sensors 14 far from the workstation track scans the detection reference 15, the compensation track 1 is in a horizontal state.
[0030] The RGV shuttle car compensation track mechanism provided in this embodiment of the invention has the following usage steps and transmission process between its components:
[0031] The initial state of the compensation track 1 is vertical. When in use, the adjustment motor 5 is started. The adjustment motor 5 controls the rotation of the transmission shaft 8 through the chain transmission assembly 6. The rotating transmission shaft 8 drives the compensation track 1 to rotate through the gear transmission assembly 4. During the rotation of the compensation track 1, when a set of detection sensors 14 far away from the workstation track scans the detection reference piece 15, it is determined that the compensation track 1 is in a horizontal state, and the adjustment motor 5 is controlled to stop. Subsequently, the mother car pushes the trolley from the trolley track 12 along the compensation track 1 to the workstation track, and finally smoothly transports the transformer coil and other materials to the connecting workstation.
