Abstract
The utility model relates to a top climbing ladder of a rail engineering vehicle. The top climbing ladder of the rail engineering vehicle comprises two bolts, wherein the two bolts are installed on a vehicle body, and are respectively arranged on two sides of a top climbing ladder body. Fixed lugs are fixedly installed on the two sides of the top climbing ladder body in a corresponding mode, grooves with downward openings are arranged in the fixed lugs, the bolts are respectively installed in the grooves of corresponding fixed lugs in a clamping mode, and the bolts are fastened through nuts. The top climbing ladder of the rail engineering vehicle adopts a fixing mode of butterfly nuts, and can be directly fixed by hand power. In addition, the butterfly nuts are fixed on the top climbing ladder through chains, and are incapable of being lost.
Description
Technical field
The utility model relates to a kind of track engineering vehicle climbing ladder.
Background technology
Existing rail engineering automobile climbing ladder adopts bolt directly to be fixed on the car body, after need the employing instrument when using climbing ladder loosering a bolt, can take off ladder at every turn; After using, need again with the instrument fixed ladder that tights a bolt.Therefore the using and deposit all inconveniently of ladder, and the little fasteners such as bolt, pad easily lose in dismounting and preservation process, for the locomotive operation personnel, use inconvenience.
Summary of the invention
The purpose of this utility model is, for the deficiencies in the prior art, provides a kind of track engineering vehicle climbing ladder, easy installation and removal, and fastener is difficult for losing.
The technical solution of the utility model is, a kind of track engineering vehicle climbing ladder, comprise two bolts that are installed on the car body and place respectively climbing ladder main body both sides, the corresponding fixedly ear of installing in described climbing ladder main body both sides, and fixedly ear is provided with the groove that Open Side Down, described bolt is installed on respectively in the groove of corresponding fixedly ear, and by the fastening nuts bolt.
Nut adopts fly nut.
The climbing ladder main body is passed through fixedly, and then ear-hang uses fly nut to tighten fixing on bolt; Need not pass through instrument when dismounting is used, just can unscrew fly nut with hand, take out climbing ladder and use.
Described nut is connected with climbing ladder by chain, prevents loss.
The utility model has adopted the fixed form of fly nut, can directly with hand-power climbing ladder be fixed, and fly nut is fixed on the ladder by chain, can not lose.
