Description

Technical Field

[0001] This invention relates to the field of bogie frame processing technology, and in particular to an automatic lifting, flipping, loading and unloading device and process for bogie frames. Background Technology

[0002] As a key component of the bogie in the running gear of railway vehicles, the bogie frame directly bears the weight, traction, and braking forces of the vehicle. Before the traction and braking units are assembled onto the bogie frame, all mounting surfaces and holes of the bogie frame need to be machined. Due to the large size and irregular shape of the bogie frame, it has the characteristics of many machining surfaces and holes, long machining time, and high machining accuracy requirements. Generally, it is necessary to machine both sides of the bogie frame to complete the process. The traditional process is to use a manually operated overhead crane to lift the bogie frame onto the bogie frame reverse assembly machining fixture for clamping and machining. After the bogie frame reverse assembly machining is completed, the overhead crane is then manually operated to lift the bogie frame from the bogie frame reverse assembly fixture. The frame is hoisted to the ground from the jig, and then manually operated by an overhead crane to rotate it 180° to the upright position. The frame is then manually hoisted onto the upright processing jig for clamping and processing. After the upright processing is completed, the frame is manually hoisted away from the upright processing jig by an overhead crane. The hoisting and rotating of the frame is entirely dependent on manual operation of the overhead crane, which results in low efficiency and safety issues. In the existing technology, there are also automatic frame rotating devices fixed on the ground, but they have not been put into practical use due to the long frame clamping and rotating operation time and the limited functionality.

[0003] Therefore, based on the above problems, how to solve the problem that traditional frame hoisting and flipping processes affect the processing efficiency of both sides of the frame has become an important technical problem that needs to be solved by those skilled in the art. Summary of the Invention

[0019] Furthermore, the lifting beam mechanism also includes a lifting nut that is screw-driven with the lifting screw, and a lifting slider that is slidably connected with the lifting rail, wherein the lifting nut is fixedly connected to the axle box device.

A transverse motor 4.2 provides rotational driving force to the left and right rotating lead screws 4.1. The lower part of the sliding blocks is slidably connected to the transverse rail 3.3 of the longitudinal beam mechanism 3. The transverse beam mechanism 4 is equipped with a lifting beam mechanism 2 via two sliding blocks. In operation, the two lifting beam mechanisms 2 can be relatively displaced to adapt to the width of the frame under the drive of the sliding blocks, thus facilitating the clamping of the frame. Alternatively, they can be displaced in opposite directions away from the frame under the drive of the sliding blocks. The release frame is provided in which the axle box device 1.8 of the frame clamping and flipping mechanism 1 is sleeved on the bottom end of the lifting beam mechanism 2.

Two longitudinal steel rails 5.3 are arranged parallel to each other at the top of the truss mechanism 5. The longitudinal beam mechanism 3 rolls in contact with the longitudinal steel rails 5.3 through rollers. The longitudinal beam mechanism 3 is also equipped with a longitudinal movement motor 3.1.

The frame loading and unloading station 6 includes a frame forward loading station and a frame reverse loading station. Automatic loading and unloading operations before and after frame processing (for both forward and reverse loading) can be achieved through the frame loading and unloading station 6. When frame reverse loading or forward loading flipping is required, the device can automatically clamp the frame. The frame is automatically hoisted to the frame flipping station 7 for automatic frame flipping operation. The automatic frame loading and unloading station 8 is located on the side of the frame flipping station 7 away from the frame loading and unloading station 6. The automatic frame loading and unloading station 8 can realize the automatic storage of the frame on the frame support device 8.1 before and after processing. This device can realize the automatic clamping of the frame to be processed and hoisting it to the frame loading and unloading station. After the frame is processed, it can realize the automatic clamping of the frame from the frame loading and unloading station and hoisting it to the automatic frame loading and unloading station.
