Abstract
The utility model discloses a kind of electric expansion beam for railway breakdown lifting, it relates to railway breakdown field, its bag telescopic shaft, sliding sleeve, feather key, nut, leading screw, limiting block, main cover and transmission device.Its reasonable in design, modern design is unique, simple to operate, easy to use, and the block construction in this device is simple, without the need to loaded down with trivial details processing, saves manufacture tooling cost, and easy to operate, very favourable to railway breakdown.
Description
technical field:
The utility model relates to railway breakdown, is specifically related to a kind of electric expansion beam for railway breakdown lifting.
background technology:
Railroad train rescue is a special rescue industry, occurs overstepping the limit once train is in operation, and the accident such as to tumble just needs breakdown train to be fallen by settlement of accident immediately, recovers the unimpeded of railway.
Railway breakdown train is a kind of breakdown train with hoisting crane, and the impaired grave accident be seriously separated to traction bridge with bogie truck of every train, must set out this train rescuing.During rescue, often adopt wrecking crane sling half accident train method rescue, the suspension centre of broken-down vehicle is that two of bottom hold and revoke, these two are held the both sides of revoking and being positioned at train, and the suspension centre of breakdown train, not generally suspension hook, but a hanging beam, hanging beam has two suspension centres, the width between centers of suspension centre is greater than the width of train, and the length of whole beam is more greater than the width of train.Hanging beam can be sling from both sides accident train.
Breakdown train will leave for broken-down vehicle place from breakdown train section, and in this section of interval, train needs to run, and run duration, the length of hanging beam is less than the overall width of train, and that will stretch out rapidly after place of arrival arrives suitable length.
utility model content:
In order to solve the problem, the utility model provides a kind of technical scheme: a kind of electric expansion beam for railway breakdown lifting, is made up of telescopic shaft, sliding sleeve, feather key, nut, leading screw, limiting block, main cover, transmission device; Described transmission device is fixedly connected on main putting, and the output shaft of described transmission device is positioned at the inside of main cover chamber; Described leading screw is two, and two leading screws arrange in the left and right chamber of main cover respectively, are fixedly connected with respectively with the output shaft of transmission device; Described sliding sleeve is two, and two sliding sleeves are slidably connected in left and right two chambers of main cover respectively; Slidably connect telescopic shaft respectively in described two sliding sleeves, described two telescopic shafts are all linked together by nut and lead screw shaft; One end that described two sliding sleeves are positioned at main cover chamber interior is also fixedly connected with a limiting block respectively; Describedly in the default guide groove of telescopic shaft and sliding sleeve and sliding sleeve and main cover, be equipped with a feather key.
As preferably, in described telescopic girder, be also provided with the buting iron of restraint beam minimax stroke.
As preferably, the mid point of described telescopic girder is provided with a shackle.
The beneficial effects of the utility model: its reasonable in design, modern design is unique, simple to operate, easy to use, and the block construction in this device is simple, without the need to loaded down with trivial details processing, saves manufacture tooling cost, and easy to operate, very favourable to railway breakdown.

detailed description of the invention:
As shown in Figure 1, Figure 2 and Figure 3, this detailed description of the invention by the following technical solutions: be made up of telescopic shaft 1, sliding sleeve 2, feather key 3, nut 4, leading screw 5, limiting block 6, main cover 7, transmission device 8; Described transmission device 8 is fixedly connected on main cover 7, and the output shaft of described transmission device 8 is positioned at the inside of main cover 7 chamber; Described leading screw 5 is two, and two leading screws 5 are arranged in the left and right chamber of main cover 7 respectively, are fixedly connected with respectively with the output shaft of transmission device 8; Described sliding sleeve 2 is two, and two sliding sleeves 2 are slidably connected in left and right two chambers of main cover 7 respectively; Slidably connect telescopic shaft 1 respectively in described two sliding sleeves 2, described two telescopic shafts 1 are all linked together by nut 4 and leading screw 5 axle; One end that described two sliding sleeves 2 are positioned at main cover 7 chamber interior is also fixedly connected with a limiting block 6 respectively; Describedly in telescopic shaft 1 and sliding sleeve 2 and sliding sleeve 2 with the default guide groove of main cover 7, be equipped with a feather key 3.
Wherein, the buting iron of restraint beam minimax stroke is also provided with in described telescopic girder; The mid point of described telescopic girder is provided with a shackle.
The utility model using state is: motor reducer drives leading screw 5 to rotate by Chain conveyer, left-right rotaries owing to being the screw thread at leading screw 5 and nut 4 two ends, suppose to open when rotating forward, leading screw 5 nut 4 promotes telescopic shaft and moves along prolonging direction, after telescopic shaft stretches out certain amount, the step of telescopic shaft 1 cylindrical withstands the step of sliding sleeve 2, and sliding sleeve 2 extends together with telescopic shaft 1, until range touches dead buting iron.Motor reversal, then telescopic shaft 1 and sliding sleeve 2 shorten, until minimum stroke touches dead buting iron.
More than show and describe groundwork of the present utility model and principal character and advantage of the present utility model.The technical personnel of the industry should be understood; the utility model is not restricted to the described embodiments; what describe in above-described embodiment and specification sheets just illustrates principle of the present utility model; under the prerequisite not departing from the utility model spirit and scope; the utility model also has various changes and modifications, and these changes and improvements all fall within the scope of claimed the utility model.The claimed scope of the utility model is defined by appending claims and equivalent thereof
.
