Problems solved by technology
[0002] HDX1 is a heavy-duty freight electric locomotive, and the drawbar is an important connection between the bogie and the car body. It plays the role of transmitting traction and braking force. The strength and stiffness of the drawbar, installation conditions and daily maintenance status are directly related to The safe operation of the locomotive, so the daily maintenance of the drawbar is particularly important. The HDX1 electric locomotive is a new generation of electric locomotive jointly developed by CRRC Zhuzhou Electric Locomotive Co., Ltd. Rod 1, drawbar 2, drawbar pin, sliding sleeve and slip ring, which involves magnetic particle inspection of the weld seam of drawbar 1 and drawbar 2, flaw detection of drawbar pin, and maintenance of slip ring and sliding sleeve during maintenance , the original maintenance work is to use a hand-held hydraulic cylinder and a fixed disassembly table to remove the drawbar pin, slip ring, and sliding sleeve, and use a double-hook crane to flip over the drawbar 1 and drawbar 2 for flaw detection, which not only occupies A large area of operating stations has been created, and there are great safety hazards in the process of turning over

Embodiment Construction
[0051] The present invention will be described in further detail below in conjunction with the accompanying drawings.
[0052] Such as figure 1 figure 2 Shown: The frame 1 of the maintenance platform is welded by high-quality rectangular steel pipes and steel plates. It has the characteristics of high strength, good rigidity, and reasonable and beautiful structure, which fully matches the strength and rigidity requirements of the platform during the maintenance process.
[0053] The translation unit 2 is one of the functional units of the maintenance platform, and it consists of a dovetail slide 6, a supporting plate 7, a second lug 8, a dovetail base 9, a telescopic oil cylinder 10, a first lug 11, and a cylindrical pin 12. The dovetail base 9 and the first lug 11 are fixed on the frame 1; the dovetail slide 6 is fixedly connected to the supporting plate 7, and the second lug 8 is also fixedly connected to the supporting plate 7, and the three form a fixed whole; the doveta...

A locomotive traction rod inspection and repair platform and inspection and repair method comprise a frame, a translation unit, a lifting unit and a flipping unit are respectively arranged on two sideof that frame, and a dismounting unit is installed at the upper end of the middle part of the frame; The disassembly and assembly unit comprises a longitudinal stopper block and a transverse combinedstopper plate for stopping the traction rod in a longitudinal position and a horizontal position, At that rear end of the transverse combination limit plate, a dismounting cylinder is arrange, At that front end of the transverse combination limit plate is provided with a traction rod pin and a sliding sleeve, and the transverse combination limit plate is two groups, and the gap between the two groups is provide with a traction rod, which integrates the disassembly and assembly of the traction rod pin, the sliding ring and the sliding sleeve, the overturning detection of the traction rod, andthe integral assembly of the traction rod, and has the characteristics of small occupying work position, simple operation, high safety, and high working efficiency.
Description
technical field [0001] The invention relates to the technical field of maintenance platforms, in particular to a maintenance platform and a maintenance method for a drawbar of a locomotive. Background technique [0002] HDX1 is a heavy-duty freight electric locomotive, and the drawbar is an important connection between the bogie and the car body. It plays the role of transmitting traction and braking force. The strength and stiffness of the drawbar, installation conditions and daily maintenance status are directly related to The safe operation of the locomotive, so the daily maintenance of the drawbar is particularly important. The HDX1 electric locomotive is a new generation of electric locomotive jointly developed by CRRC Zhuzhou Electric Locomotive Co., Ltd. Rod 1, drawbar 2, drawbar pin, sliding sleeve and slip ring, which involves magnetic particle inspection of the weld seam of drawbar 1 and drawbar 2, flaw detection of drawbar pin, and maintenance of slip ring and sli...
