Description
Technical field:
The utility model relates to the repair apparatus of rolling stock, particularly is a kind of composite type melt pit car lifting J-Horner that the permutation rolling stock is overhauled.
Technical background:
The ground pit type car lifting J-Horner is that some interior unwheeling device of melt pit and ground rails of placing constitute a continuous track jointly, a unwheeling device comprises that the bogie truck lifting device (or claiming bogie truck lifting rail) in the melt pit constitutes with the car body lifting device (or claiming car body lifting post) that its both sides are provided with, motor train unit to be keeped in repair sail above-mentioned continuous track into, and the lifting device synchronous lifting of car lifting J-Horner will be reorganized motor train unit and be given rise to a certain height.The ground pit type car lifting J-Horner is one of extensive visual plant that adopts in domestic and international EMU maintenance base, its effect is not understand under the situation about compiling at the permutation motor train unit its (comprising bogie truck and car body) erected synchronously, can change arbitrary or whole bogie truck as required, also can as required bogie truck or car body synchronous lifting arbitrary height be carried out upkeep operation to its bottom.Existing domestic EMU serves as basic marshalling with 8 joint compartments all, in real-world operation, also have the motor train unit connection of two basic marshallings is hung, form the motor train unit that 16 joint compartments are organized as row, but will 16 in upkeep operation the motor train unit of joint compartments marshalling separate that to compile be two row, be a unit so unwheeling equipment in overhaul of train-set base is all compiled with 8 joint compartments.China began to introduce French Alstom in 2007, the Kawasaki, Japan heavy industry, the motor train unit of Canada Pang Badi and four companies of Siemens, these four kinds of motor train unit (are CRH1, CRH2, four kinds of models of CRH3 and CRH5) become the main passenger traffic strength of domestic intercity track and high speed railway, but because the length overall of the motor train unit of above-mentioned four kinds of models, vehicle commander's degree, middle vehicle commander's degree, wheelbase, the size of spacing is all inequality, the position of unwheeling device is subjected to the restriction of ground trapped orbit and can not moves, so neither one producer has the unwheeling repair apparatus of compatible above-mentioned vehicle simultaneously on the world market at present, ground pit type car lifting J-Horner both domestic and external is the motor train unit design-calculated at a certain type, do not possess commonality, the type of motor train unit is different with marshalling, the structure and the size of ground pit type car lifting J-Horner are different, can not satisfy the needs of the multiple vehicle of China's motor-car section.
Summary of the invention:
Goal of the invention of the present utility model is to disclose a kind of car lifting J-Horner that can carry out the lifting upkeep operation to the motor train unit that the existing difference that is made of different vehicle oad, length between truck centers, vehicle wheelbase etc. is organized into groups.
Realize that technical solution of the present utility model is as follows: comprise electronic control part and a plurality of unwheeling device that constitutes by the car body lifting device 2 of bogie truck lifting device 1 and the setting of bogie truck lifting device 1 both sides of controlling car lifting J-Horner, key is that unwheeling device file is arranged in the melt pit that is provided with at interval, the unwheeling device that a plurality of files are arranged distributes to bilateral symmetry with the mid point of file length, the arrangement mode of one side is that the first unwheeling device 3 is the basic point setting with the mid point, every first trapped orbit 14 two second～the 3rd adjacent unwheeling devices 4 are set, 5, every second trapped orbit 15 the 4th～the 6th adjacent unwheeling device 6 is set again, 7,8, every the 3rd trapped orbit 16 the 7th～the 9th adjacent unwheeling device 9 is set again, 10,11, every the 4th trapped orbit 17 the tenth～the 11 unwheeling device 12 is set again, 13.
Also can be provided with the first short trapped orbit 18 between the mid point of described first unwheeling device 3 and file length, between second and third unwheeling device 4,5, also be provided with the second short trapped orbit 19.
The length of the described first unwheeling device 3 is 3700mm, the length of the second unwheeling device 4 and the 3rd unwheeling device 5 is 4750mm, the length of the 4th unwheeling device 6 and the 5th unwheeling device 7 is 4600mm, the length of the 6th unwheeling device 8 is 3700mm, the length of the 7th unwheeling device 9, the 8th unwheeling device 10 and the 9th unwheeling device 11 is 4600mm, and the length of the tenth unwheeling device 12 and the 11 unwheeling device 13 is 4000mm; The length of described first trapped orbit 14 is for equaling or being slightly larger than 13815mm, the length of second trapped orbit 15 is for equaling or being slightly larger than 11930mm, the length of the 3rd trapped orbit 16 is for equaling or being slightly larger than 10555mm, the length of the 4th trapped orbit 17 is for equaling or be slightly larger than 8785mm, and the length of the first short trapped orbit 18 and the second short trapped orbit 19 is respectively 3430mm and 2070mm.
Described car body lifting device 2 belows are provided with the road wheel 22 of motor-driven active walking.
The holder of described car body lifting device 2 23 is provided with the cross travel device.
The utility model can compatible various motor train unit maintenance, the first is the benchmark that the ground pit type car lifting J-Horner is arranged with the center line of motor train unit length overall, arrange to the two ends, the left and right sides of motor train unit successively, can make the position difference of the corresponding bogie truck of various motor train unit reduce 1/2 like this, help simplified structure; It two determines the length of each bogie truck lifting device make most of bogie trucks of different motor train unit finish lifting on a bogie truck lifting device, so the bogie truck lifting device has multiple length dimension by the motor train unit geometric parameter of compatibility; Its three lifting that when the bogie truck position difference of compatible motor train unit is big, realizes different motor train unit by the number that increases the bogie truck lifting device.The motor train unit of 8 joint marshallings have 16 bogie trucks theoretically, just can satisfy the unwheeling requirement as long as 16 bogie truck lifting devices are set.But lift work for the different motor train unit bogie trucks of compatibility, need to increase several bogie truck lifting devices, make the bigger bogie truck of position difference finish the unwheeling operation by the bogie truck lifting device that increases, so the utility model is of universal significance to the commonality that solves the ground pit type car lifting J-Horner, can be used for the unwheeling requirement of multiple model motor train unit.
