A double-head jaw type wheel set unloading machine

Abstract

A double-head jaw type wheel set unloading machine, which includes a base, left and right machine heads, left and right main oil cylinders, a workbench, a detection system, a hydraulic system, and an electrical control system. The two ends of the base are respectively equipped with The machine head is shaped like a U, and tilted at a certain angle. There is a main oil cylinder in the middle of the U-shape, claw mechanisms are provided at both ends of the U-shape, and opening and closing drive devices are respectively installed on both sides of the U-shape. The base is equipped with a workbench. , There are guide rails and forward and backward driving devices under the workbench, two ends of the above workbench are provided with supporting wheel frames, and linear guide rails are arranged below it. The beneficial effect of the present invention is that the edge of the wheel set is unloaded by the claws, which solves the problem that the existing unloading machine cannot be unloaded because the wheel set is close to the chassis; The height of the whole machine is convenient for the workpiece to enter and exit without interference; the machine head is fixed and has good rigidity; the double-head oil cylinder works, and the withdrawal and unloading are completed without turning the head, and the work efficiency is high.

Description

technical field [0001] The invention relates to equipment machinery for railway locomotives, in particular to a double-head jaw type wheel set unloading machine. It is suitable for unloading and pressure inspection of wheels, axles, brake discs, gears, etc. . Background technique [0002] With the speed increase of trains, especially in recent years, in order to adapt to the rapid development of the railway freight transportation market, the speed increase of freight trains and the construction of high-speed railways, and the operation of high-speed electric locomotives with a speed of 200km / h have changed from the previous axle-holding boxes to To meet the needs of stable, safe and reliable high-speed transportation, the emergence of special wheel sets with high-power motors, gearboxes, 2 to 3 brake discs, imported wheelsets, etc., brings various high-precision wheel sets for pressing and unloading. And the amount of maintenance is increasing, and the precision of press-f...

Problems solved by technology

[0002] With the speed increase of trains, especially in recent years, in order to adapt to the rapid development of the railway freight transportation market, the speed increase of freight trains and the construction of high-speed railways, and the operation of high-speed electric locomotives with a speed of 200km / h have changed from the previous axle-holding boxes to To meet the needs of stable, safe and reliable high-speed transportation, the emergence of special wheel sets with high-power motors, gearboxes, 2 to 3 brake discs, imported wheelsets, etc., brings various high-precision wheel sets for pressing and unloading And the amount of maintenance is increasing, and the precision of press-fitting is high, the difficulty of unloading and maintenance is high, and the quality of unloading is improved. The wheels, brake discs, gears, gearboxes and The pressing and dismounting of special wheel sets not only has poor precision, low efficiency, high noise, and high labor intensity, but also has poor quality of pressing and dismounting, and is unsafe, especially for high-speed electric locomotives with gearboxes and high-power motors. , 2 to 3 brake discs, because the gap between the wheel set and the gearbox is too small or even close, the insert plate or disassembly head of the existing wheel set unloading machine cannot enter it, so that the wheel set cannot be unloaded at all

For this reason, the applicant has applied for a patent for a wheel set pressure detection and unloading machine, which solves the above problems, but it is still not ideal. The workpiece needs to be rotated to complete the unloading during the working process, which delays time and affects efficiency, and the rigidity appears. insufficient
