Abstract
The utility model provides a car end dog-ear door connection structure for rail vehicle which characterized in that: the double-ended double-screw bolt type angle cock comprises a welding flange, a transition joint, a fixing flange, a double-ended double-screw bolt, a flat washer, a spring washer and a nut, wherein the welding flange is connected with a main pipeline at the vehicle end by adopting a welding structure, the transition joint is positioned between the welding flange and the fixing flange, the transition joint and the welding flange are connected together by the double-ended double-screw bolt, the flat washer, the spring washer and the nut, and the transition joint is in threaded connection with the angle cock. According to the invention, because the matching surfaces of the transition joint, the welding flange and the fixing flange are a plane and a cylindrical surface, when the angle cock is installed, the angle cock can be adjusted at any angle along with the transition joint, so that the angle cock is at a designed angle, the stud is matched with the flat washer, the spring washer and the nut for use, and can be prevented from loosening through torque pre-tightening, and the installation is convenient.
Description
Technical Field
The invention belongs to the technical field of rail transit, and particularly relates to a vehicle end angle cock connecting structure for a rail vehicle.
Background
The angle cock is arranged at the train end train pipe and the main air pipe of the railway vehicle, and when the supply of compressed air in the train pipe and the main air pipe needs to be cut off for some reasons (such as being at the tail part of a train, splitting and weaving the train or testing), the operation can be realized by operating the angle cock. The connection structure of the angle cock is convenient to install and prevents loosening.
The angle cock, the train pipe and the main air pipe of the railway vehicle end in China all adopt threaded connection structures. The threaded connection structure is adopted, so that the installation angle of the angle cock is difficult to adjust during installation, and the angle cock is inconvenient to install; during use, there is a risk of leakage if the threaded connection is loose.
Disclosure of Invention
The invention aims to solve the technical problem of designing a connecting structure of a folding angle cock, so that the folding angle cock is simple and convenient to mount and is not easy to loosen.
In order to solve the technical problem, the invention provides a vehicle end angle cock connecting structure for a railway vehicle, which is characterized in that: the double-ended double-screw bolt type angle cock comprises a welding flange, a transition joint, a fixing flange, a double-ended double-screw bolt, a flat washer, a spring washer and a nut, wherein the welding flange is connected with a main pipeline at the vehicle end by adopting a welding structure, the transition joint is positioned between the welding flange and the fixing flange, the transition joint and the welding flange are connected together by the double-ended double-screw bolt, the flat washer, the spring washer and the nut, and the transition joint is in threaded connection with the angle cock.
According to the invention, because the matching surfaces of the transition joint, the welding flange and the fixing flange are a plane and a cylindrical surface, when the angle cock is installed, the angle cock can be adjusted at any angle along with the transition joint, so that the angle cock is at a designed angle, the stud is matched with the flat washer, the spring washer and the nut for use, and can be prevented from loosening through torque pre-tightening, and the installation is convenient.
Drawings
FIG. 1 is a schematic structural view of the present invention;
FIG. 2 is a view from the direction B of FIG. 1;
fig. 3 is a sectional view taken along line a-a of fig. 1.
Detailed Description
Referring to fig. 1, 2 and 3, the embodiment of the invention comprises a welding flange 1 of a vehicle end main pipeline, a transition joint 2, a fixing flange 3, a stud 4, a flat washer 5, a spring washer 6, a nut 7, a sealing ring I8 and a sealing ring II 9. The welding flange is connected with the main pipeline 11 of the vehicle end by adopting a welding structure. The transition joint 2 is positioned between the welding flange and the fixed flange, and the fixed flange 3, the transition joint 2 and the welding flange 1 can be connected together through the stud bolt 4, the flat washer 5, the spring washer 6 and the nut 7. The transition joint 2 is connected with the angle cock through screw threads. The sealing rings I and II 9 play a sealing role. Because the matching surfaces of the transition joint 2, the welding flange 1 and the fixing flange 3 are planes and cylindrical surfaces, when the angle cock 10 is installed, the angle cock can be adjusted at any angle along with the transition joint 2 to enable the angle cock to be at a designed angle. The stud 4 is matched with the flat washer 5, the spring washer 6 and the nut 7 for use, and can be prevented from loosening through torque pre-tightening.
Claims (1)
1.
