Description

The attaching/detaching apparatus of train wheel axle gear box rod nut
Technical field
The utility model belongs to the attaching/detaching apparatus of train wheel axle gear box rod nut, particularly a kind of train wheel The attaching/detaching apparatus of axle gear box rod nut.
Background technology
Because the curve of plant area's rail track, ramp are more, frequent, GKIC type train wheel axletree teeth are used plus locomotive The pull bar cushion pad abrasion that roller box is connected with bogie is very fast, has a number of locomotive to change pull bar cushion pad every year. The clamping nut of cushion pad must be first pulled down before replacing pull bar cushion pad, because nut is larger, position is in semicircular cylinder, under car Working space is narrow and small, and common wrench is not torn open not get off at all.Due to no special wrench for dismounting, every time with car lifting J-Horner by locomotive Erect, release bogie and wheel changes pull bar cushion pad to axle gear box, axle gear box rod nut is torn open in wheel Many times are occupied in terms of dress, nut can be also damaged sometimes, have impact on the repair schedule and safety of locomotive.In order to improve maintenance Progress, workload is reduced, by research, devise GKIC train wheel axle gear box rod nut wrench for dismounting, do not pushing away Go out bogie and wheel changes pull bar cushion pad to axle gear box, so that the maintenance to locomotive running gear is brought convenience.
Utility model content
The purpose of this utility model is to provide a kind of attaching/detaching apparatus of train wheel axle gear box rod nut, and it is tied Structure is reasonable, simple to operate, easy to use, can change pull bar cushion pad to axle gear box not releasing bogie and taking turns, Significant effect in terms of need to changing pull bar cushion pad is repaiied in train wheel replacing, the rotation of wheel tread wheel rim, the labor of worker can be reduced Fatigue resistance, improve operating efficiency.
What the purpose of this utility model was realized in:A kind of dismounting dress of train wheel axle gear box rod nut Put, including pull bar is set on GKIC train wheel axle gear boxs, rod nut is installed on pull bar, rod nut is torn open Assembling device is made up of wrench for dismounting and drawstring, and the structure of wrench for dismounting is set for the front end of tabular brace arm has interior hexagonal hole Disk, the interior hexagonal hole of disk with rod nut is dynamic coordinates, link is set in the rear end of brace arm, and the length of brace arm is 300-400mm, when dismounting rod nut, the interior hexagonal hole of wrench for dismounting disk is engaged with rod nut, in brace arm rear end Link on be connected to drawstring, the other end of drawstring is by external force drawstring.
Principle of the present utility model is by the way that locomotive car body to be erected to certain height, is not releasing bogie and wheel to car In the case of shaft gear case, rod nut wrench for dismounting is enclosed on rod nut, the root long degree of annulus system one of spanner afterbody closes Suitable, the reliable nylon rope of intensity.People stands in the lateral surface of locomotive, and a little is by nut Panasonic as tug-of-war;New cushion pad After loading onto, equally nut is little by little screwed in the another side of locomotive, assembling in place, finally falls locomotive car body, changes The work of pull bar cushion pad is completed.
Major design content is as follows:
In the case where not releasing bogie and wheel to axle gear box, locomotive car body can only erect 400-500 millimeters Highly.Due to rod nut wrench for dismounting torque arm length under by locomotive narrow space limited, rod nut can not be torn open Under.Annulus can be welded in the afterbody of the wrench for dismounting arm of force, be equipped with long 6-8 rice, the manpower drawstring of 3 tons of load-bearing, utilize the original of tug-of-war For reason by the active force of the spanner arm of force by being transferred under car outside car, active force, such pull bar spiral shell can be increased by increasing the quantity of personnel Cap can be pulled down, loaded onto, and everything goes well with your work carries out for the replacing of pull bar cushion pad, substantially increases repair schedule.
Improvement effect
Very easily GKIC types, GKIB type train wheel axle gear box rod nuts can be entered using the utility model Row dismounting, it is simple to operate, it is easy to use, bogie and wheel are not being released to axle gear box or in train wheel replacing, wheel pair The rotation of tread wheel rim, which is repaiied, need to change pull bar cushion pad aspect significant effect, and repair schedule was shorten to 4 hours by former 8 hours, carried High repair schedule 50%.
The utility model is rational in infrastructure, simple to operate, easy to use, realizes and is not releasing bogie and wheel to axletree tooth Roller box changes pull bar cushion pad, train wheel is changed, effect in terms of need to changing pull bar cushion pad is repaiied in the rotation of wheel tread wheel rim Significantly, the labor intensity of worker is reduced, improves operating efficiency.
Brief description of the drawings
The utility model is further described below in conjunction with accompanying drawing, Fig. 1 illustrates for the utility model front view structure Figure, Fig. 2 are the structural representation of Fig. 1 left view, and Fig. 3 is the main structure diagram of wrench for dismounting.
Embodiment
A kind of attaching/detaching apparatus of train wheel axle gear box rod nut, as shown in Figure 1, Figure 2, Figure 3 shows, including GKIC machines Wheel is installed with rod nut 3 to setting pull bar 2 on axle gear box 1 on pull bar 2, the attaching/detaching apparatus of rod nut 3 by Wrench for dismounting 4 and drawstring 5 are formed, and the structure of wrench for dismounting 4 sets the circle with interior hexagonal hole for the front end of tabular brace arm Disk 7, interior hexagonal hole and the dynamic cooperation of rod nut 3 of disk, link 6 is set in the rear end of brace arm, the length of brace arm is 300-400mm, when dismounting rod nut 3, the interior hexagonal hole of wrench for dismounting disk 7 is engaged with rod nut 3, after brace arm Drawstring 5 is connected on the link 6 at end, the other end of drawstring 5 draws drawstring 5 by external force.The length of drawstring 5 is 5-8 rice, drawstring 5 by Nylon rope is formed.
