Abstract
The utility model relates to the fixing torsion-proof field of the railway locomotive, in particular to an end-of-car angle cock torsion-proof mechanism, which comprises an angle cock, a connection plate and a connector which is arranged on one end of the angle cock and is connected with a car body wind pipe. One end of the connection plate is fixedly connected with a mounting seat which is fixed on the end of the car, and the other end thereof is fixedly connected with the angle cock through an angle cock bolt. By restricting the rotation freedom of angle cock in the longitudinal direction and along the car body wind pipe, the fixture restriction of the angle cock is realized; and moreover, the end-of-car angle cock torsion-proof mechanism has simple structure, good torsion-proof performance, convenient operation, low cost and high popularization value.
Description
Technical field
The utility model relates to the fixing anti-of railway locomotive and turns round the field, is specially the anti-mechanism of turning round of a kind of car end angle cock.
Background technology
With reference to shown in Figure 1, the anti-mechanism of turning round of a kind of HXD1 locomotive car end angle cock of prior art, angle cock 1 one ends are fixed in by joint 5 on the car body airduct 7 of car end 4, and the other end and hose coupling assembly or total wind hose coupling assembly or average hose coupling assembly are connected.If HXD1 locomotive car end angle cock is not carried out fixed constraint, angle cock just has vertically and around the degree of freedom of car body airduct rotation so, in the operational process of locomotive,, factors such as external force influence the connection reliability that connects airduct because can causing angle cock to vertically move with car body, the rotation of angle cock can cause the loosening of angle cock and blast connection in addition, thereby cause leakage or other the more serious fault and the accident of each piping, there is hidden danger in traffic safety, however the also not relevant at present fixing anti-mechanism of turning round.
The utility model content
Utility model purpose of the present utility model is: at locomotive in the prior art in operational process since factor such as external force cause angle cock to vertically move easily and rotate the leakage of each piping that causes or the defective of other more serious faults and accident with car body, and provide a kind of car end angle cock the anti-mechanism of turning round, ensure the traffic safety of locomotive.
The technical scheme that the utility model adopted is: a kind of car end angle cock is anti-turns round mechanism, comprises angle cock, connecting panel and is contained in the joint that angle cock one end links to each other with the car body airduct.Described connecting panel one end and the mount pad Joint that is fixed on the car end, the other end is fixed together from strap bolt and angle cock by angle cock.
This car end angle cock is anti-turn round mechanism by the restriction angle cock at car body vertically and around the degree of freedom of car body airduct rotation, guarantee the position of angle cock apart from the car end, realization is stopped leakage or other more serious fault and accident that locomotive causes angle cock to vertically move with car body easily and rotates each piping that causes owing to factors such as external force to the angle cock fixed constraint in operational process.
The beneficial effects of the utility model are: the utility model by the restriction angle cock at car body vertically and around the degree of freedom of car body airduct rotation, realized that to the angle cock fixed constraint simple in structure, anti-to turn round performance good, easy to operate, cost is low.

The specific embodiment
The anti-mechanism of turning round of a kind of car end angle cock, as shown in Figure 4, angle cock 1 one ends are fixed on the car body airduct 7 of HXD1 locomotive car end 4 by joint 5, a mount pad 3 in addition is welded in the appropriate location of car end 4, according to angle cock 1 desired position and connecting panel 2 of angle design as Fig. 2～3, then connecting panel 2 one ends are fixed by bolts on the mount pad 3 of car end 4, fixing on the other end and the angle cock 1 from strap bolt 6, the other end of angle cock 1 and hose coupling assembly or total wind hose coupling assembly or on average the hose coupling assembly be connected.Pass through the fastening of connecting panel 2 and bolt like this, make angle cock 1 and mount pad 3, also be the equal of to form with car end 4 to be rigidly connected, so both limited angle cock 1 at car body vertically and around the degree of freedom of car body airduct rotation, also guaranteed simultaneously the position of angle cock 1 apart from car end 4, further improve the standardization that angle cock 1 is installed, stop leakage or other more serious fault and accident that locomotive causes angle cock to vertically move with car body easily and rotates each piping that causes owing to factors such as external force in operational process.
