Description

Technical Field

[0001] This utility model relates to the field of bogie frame technology, specifically a novel bogie frame tilting device. Background Technology

[0002] As is well known, in existing rail transit, the bogie frame is an important component of the vehicle, and its inspection and maintenance are crucial. However, the traditional bogie frame flipping method faces many challenges.

[0003] Specifically, existing tilting devices are often complex in structure and cumbersome in operation, and are prone to safety hazards during the tilting process. In particular, when tilting and overhauling bogie frames, traditional tilting devices often fail to achieve precise control and stable support of the bogie frames, and lack effective locking and fixing mechanisms. Shaking or deviation is likely to occur during the tilting process, making it difficult to carry out maintenance work smoothly. In addition, traditional tilting devices are difficult to adapt to the tilting requirements of different models and specifications of bogie frames. Utility Model Content

[0004] (a) Technical problems to be solved

[0005] To address the shortcomings of existing technologies, this utility model provides a novel bogie frame tilting device.

[0006] (II) Technical Solution

[0007] To achieve the above objectives, this utility model provides the following technical solution: A novel bogie frame tilting device, comprising a fixed plate, a tilting mechanism, and support rods. The support rods are symmetrically arranged. The tilting mechanism is located on the support rods and includes a rotating rod, a turntable, and a locking box. The rotating rod is located on the inner side wall of the support rod, and a rotating motor is installed on the outer side wall of one of the support rods. The rotating rod passes through the support rod and is connected to the output end of the rotating motor. The turntable is located on the rotating rod and fits against the support rod. The locking box is located on the outer side wall of the support rod. The locking box contains a spring, a locking rod, and a sliding block. Multiple sets of springs are arranged within the locking box. The sliding block is located near one end of the locking box close to the support rod and is slidably connected to it. One end of the spring is connected to the inner side wall of the locking box, and the other end is connected to the sliding block. The locking rod passes through the locking box and the sliding block, and the locking box is slidably connected to the locking rod. Multiple sets of evenly spaced locking holes are provided on the side wall of the turntable. The locking rod passes through the locking holes and is slidably connected to them. The fixed plate is located between two of the rotating rods.

[0008] In order to enable flexible clamping according to the size and shape of different bogie frames, the present invention has the following improvements: two sets of symmetrical electric telescopic rods are provided inside the fixed plate. The electric telescopic rods are arranged in a cross shape. One end of the electric telescopic rod is connected to the inner side wall of the fixed plate, and the other end is provided with a clamping plate, which penetrates the upper side wall of the fixed plate.

[0009] In order to provide a stable support surface, the present invention is improved by providing a placement plate on the bottom wall of the support rod, and providing buffer pads at the four corners of the bottom wall of the placement plate.

[0010] In order to increase the friction between the clamping plate and the frame, the present invention is improved by providing an anti-slip pad on the inner side wall of the clamping plate.

[0011] To make it easier to pull the locking lever, the present invention is improved by providing a hand-held pull ring at one end of the locking lever.

[0015] (III) Beneficial Effects

[0016] Compared with the prior art, the present invention provides a novel bogie frame tilting device, which has the following beneficial effects:

[0017] This novel bogie frame tilting device is equipped with a rotating motor and a rotating rod. The output of the rotating motor drives the rotating rod to rotate, which in turn drives the fixed plate to rotate, enabling rapid and stable tilting of the bogie frame. This improves tilting efficiency and reduces the labor intensity and time cost of manual operation. In conjunction with the locking box, the spring inside the locking box extends and retracts, causing the sliding block and locking rod to move. The locking rod passes through or disengages from the locking hole, achieving stable locking of the tilting mechanism. The elasticity of the spring ensures a tight fit between the locking rod and the locking hole, preventing shaking or accidental dislodgement during the tilting process, and ensuring the stability and safety of the tilting process. It is equipped with an electric telescopic rod and a clamping plate, which can be flexibly adjusted according to the size and shape of different bogie frames to ensure that the frame is stably and securely clamped.

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] Please see Figure 1-4A novel bogie frame tilting device includes a fixed plate 1, a tilting mechanism, and support rods 5. The support rods 5 are symmetrically arranged. The tilting mechanism is located on the support rods 5 and includes a rotating rod 12, a turntable 9, and a locking box 3. The rotating rod 12 is located on the inner side wall of the support rod 5, and a rotating motor 8 is located on the outer side wall of one of the support rods 5. The rotating rod 12 passes through the support rod 5 and is connected to the output end of the rotating motor 8. The turntable 9 is located on the rotating rod 12 and fits against the support rod 5. The locking box 3 is located on the outer side wall of the support rod 5 and contains springs 15, locking rods 13, and sliding blocks 14. Multiple sets of springs 15 are arranged in the locking box 3. The sliding blocks 14 are located on the locking box 3 near one end of the support rod 5 and are slidably connected to it. One end is connected to the inner wall of the locking box 3, and the other end is connected to the sliding block 14. The locking rod 13 passes through the locking box 3 and the sliding block 14, and the locking box 3 and the locking rod 13 are slidably connected. The side wall of the turntable 9 is provided with multiple sets of evenly spaced locking holes. The locking rod 13 passes through the locking holes and is slidably connected to them. The fixing plate 1 is between the two rotating rods 12. The fixing plate 1 is provided with two sets of symmetrical electric telescopic rods 11. The electric telescopic rods 11 are arranged in a cross shape. One end of the electric telescopic rod 11 is connected to the inner wall of the fixing plate 1, and the other end is provided with a clamping plate 2. The clamping plate 2 passes through the upper side wall of the fixing plate 1. One end of the locking rod 13 is provided with a hand-held pull ring 4. One of the support rods 5 is provided with an operation screen 7 on the outer wall. The operation screen 7 is signal connected to the rotating motor 8.

[0025] During use, first, place the steering frame to be flipped at an appropriate position on the fixed plate 1, ensuring the frame is aligned with the clamping plate 2. Then, activate the electric telescopic rod 11 via the operation screen 7 to move the clamping plate 2 towards the frame until it is firmly clamped. The cross arrangement of the electric telescopic rod 11 ensures even clamping of the frame, preventing swaying during flipping. After confirming the frame is stably clamped, pull the hand-held pull ring 4. The sliding block 14 and locking rod 13 move with the hand-held pull ring 4, the spring 15 contracts, and the locking rod 13 disengages from the locking hole. Then, input the rotation value via the operation screen 7. The control system in the operation panel 7 starts the rotation motor 8 according to the preset angle when the lever 12 needs to be rotated. The rotation motor 8 drives the rotating lever 12 to rotate, which in turn drives the turntable 9 and the steering frame fixed on the fixed plate 1 to start to flip. When the steering frame flips to the predetermined angle, the rotation motor 8 stops. At this time, the corresponding locking hole is aligned with the locking lever 13. Release the hand pull ring 4, and the spring 15 extends under its own elastic force, which drives the sliding block 14 to move. The sliding block 14 drives the locking lever 13 to move until the locking lever 13 passes through the locking hole and is fixed, which facilitates subsequent operations.

[0026] In practical use, it is necessary to conveniently place and support the device. In order to meet the above requirements, in this embodiment, the bottom wall of the support rod 5 is provided with a placement plate 6, and the four corners of the bottom wall of the placement plate 6 are provided with buffer pads 10.

[0027] In actual use, it is necessary to increase the friction between the clamping plate 2 and the frame to prevent the frame from slipping or being damaged during the flipping process. In order to meet the above requirements, in this embodiment, the inner sidewall of the clamping plate 2 is provided with an anti-slip pad.

[0028] In practical use, it is necessary to ensure that the turntable 9 maintains stable performance and accuracy during long-term use, extend the service life of the flipping mechanism, and reduce maintenance costs. In order to meet the above requirements, in this embodiment, the turntable 9 is made of wear-resistant alloy steel.

[0029] In practical use, precise control of the flipping process is required. To meet the above requirements, in this embodiment, the rotating motor 8 is a variable frequency motor.
