Problems solved by technology
[0002] During the flaw detection process of railway wheels, it is necessary to lift the flaw detection equipment from the vehicle bottom to the track plane. The environment of the vehicle bottom is small and it is not easy to layout. Especially in terms of lifting height, in order to meet the requirements of lifting height, the existing lifting device has to occupy more layout space, resulting in complex structure of the lifting device, increased cost, and difficult maintenance

The invention discloses a lifting device for train non-pulling wheel flaw detection. The device comprises a screw rod lifting mechanism and a hydraulic lifting mechanism. The screw rod lifting mechanism comprises screw rods, feed screw nuts, guide sliding blocks, sliding rails and a lifting panel. The screw rods are connected with the guide sliding blocks and the feed screw nuts. The hydraulic lifting mechanism is connected to the lifting panel of the screw rod lifting mechanism. The hydraulic lifting mechanism comprises a lifting platform, a lifting base plate, a jacking cylinder, a force-bearing block, guide shafts and guide bearings. The lifting base plate is connected to the upper portion of the lifting platform. The jacking cylinder is located on the lifting base plate. The guide shafts are located on the lifting panel. The guide bearings are located on the guide shafts and connected with the lifting platform. The lifting device is simple in structure, wide in lifting range, capable of achieving second-level lifting and widening the lifting range to be above 0.8m, and suitable for lifting train non-pulling wheel flaw detection equipment.
Description
technical field [0001] The invention relates to the field of elevating devices, in particular to an elevating device used for flaw detection of non-falling wheels of trains. Background technique [0002] During the flaw detection process of railway wheels, the flaw detection equipment needs to be lifted from the bottom of the car to the track plane. The environment of the bottom of the car is small and it is not easy to layout. Especially in terms of lifting height, in order to meet the requirements of the lifting height, the existing lifting device has to occupy more layout space, resulting in a complex structure of the lifting device, increased cost, and difficult maintenance. Contents of the invention [0003] In view of this, the application provides a lifting device for flaw detection of trains without falling wheels. The device has a simple structure and a large lifting range, which can realize two-level lifting and expand the lifting range to more than 0.8m, and is ...
