Background technology
Because the driver's cab side door of diesel locomotive is higher, the people enters driver's cab, generally need be by side-door arm-rest.Side-door arm-rest in locomotive cab of diesel locomotive all is the wallboard that protrudes in driver's cab side door both sides at present, it is fixing respectively two mount pads up and down on the side wall on driver's cab side door both sides, and the sweeping handrail in two ends is fixed on up and down on two mount pads up and down then.Though this structure connects simple, and the forming work of handrail is had relatively high expectations.And corroded by rainwater, service life is not long.For present Harmony diesel rail motor car locomotive, the side-door arm-rest of giving prominence to outside side wall is not too attractive in appearance especially.
Summary of the invention
The objective of the invention is to overcome the problems referred to above, a kind of easy to process, side-door arm-rest in locomotive cab of diesel locomotive device that can increase the service life is provided.
The technical scheme that realizes the object of the invention is: a kind of side-door arm-rest in locomotive cab of diesel locomotive device, comprise the wallboard and two handrails of driver's cab side door both sides, and two handrails respectively have last mount pad, time mount pad and grab rail.Respectively be provided with groove on the wallboard lateral surface of described driver's cab side door both sides, described two handrails are separately positioned in the two described grooves.The last mount pad of described handrail, down mount pad is separately fixed on the end face and bottom surface of groove, and the grab rail of described handrail is a straight-bar, the grab rail two ends respectively by upper connecting rod, lower connecting rod with the last mount pad in the groove, descend mount pad to be connected.
Described upper and lower mount pad is the U type, and described grab rail is the hollow straight-bar, and insert respectively in the chamber of mount pad and grab rail at the two ends of upper connecting rod, and insert respectively in the chamber of grab rail and following mount pad at the two ends of lower connecting rod.
Described going up between mount pad and the upper connecting rod by second screw retention, between following mount pad and the lower connecting rod by the 3rd screw retention; All welding between described upper connecting rod and the grab rail, between grab rail and the lower connecting rod.
Describedly go up between mount pad and the groove end face, down between mount pad and the groove floor respectively by first screw retention.
Each is made up of described wallboard two grooves two parts up and down, and the last mount pad in each groove is in the top of place groove, in the lower part of the bottom of last mount pad by median septum insertion groove.
In the lower part of two grooves of wallboard and be between mount pad and the grab rail and be provided with upper jacket, between grab rail and following mount pad, set sheath, the upper edge of described upper jacket is in the top of second screw, and the lower edge of described lower jacket is in the below of the 3rd screw.
The present invention has positive effect: side-door arm-rest in locomotive cab of diesel locomotive device of the present invention adopts straight-bar shape grab rail, and is easy to process relatively; Owing to be mounted in the both walls of driver's cab side door; reduce the erosion of rainwater to the outside face of handrail; handrail is played a protective role; thereby the service life of energy extension handrail; and, making the connecting portion between mount pad and upper connecting rod, upper connecting rod and the grab rail owing to be provided with upper and lower sheath, the connecting portion of grab rail and lower connecting rod, lower connecting rod and following mount pad is all besieged; so can stop rainwater to enter in the handrail, further guarantee protection to handrail.In addition, help the attractive in appearance of locomotive monnolithic case, meet the requirement of Harmony diesel rail motor car locomotive especially.
