Embodiment Construction

[0014] Embodiments of the present invention will be explained below in conjunction with the accompanying drawings.

[0015] Such as Figure 1 to Figure 3 As shown, the rail vehicle folding coupler fixing device of the present embodiment mainly includes a hook seat 3, a limit block 2, a pull rod 1, an extension spring 5 and a rotating pin 7. The hook seat 3 has a bottom plate 31 and two hooks 32 fixed on the bottom plate. The stopper 2 and the tail of the hook 32 are rotatably connected by the turning pin 7. The limit column 21 is connected, and the head size of the limit column 21 is greater than the neck size. The pull rod 1 has a pull bar oblong hole 11 through which the limit column 21 neck passes, and the hook seat 3 has a hook for accommodating the head of the limit column 21. Seat oblong hole 33. The head of the limiting block 2 has a depression 22. When the head of the limiting block 2 is lifted, the depression 22 and the hooks of the two hooks 32 form accommodating a...

Abstract

The invention relates to a railway vehicle folding coupler fixing device. The device comprises a hook seat, a limiting block, a pull rod and a tension spring, the hook seat is provided with a bottom plate and two hooks fixed on the bottom plate, and the limiting block is rotationally connected with the tails of the hooks. The limiting block is connected with the head of the pull rod through a limiting column fixed at the bottom of the limiting block, the head of the limiting block is provided with a recess, and when the head of the limiting block is lifted, the recess and the hook heads of thetwo hooks form a space for containing and limiting a coupler fixing rod. The two ends of the tension spring are connected with the hook base and the pull rod respectively and are used for pulling thepull rod, so that the pull rod pushes the limiting block through the limiting column to lift the head of the limiting block. When a coupler is folded and fixed, the coupler is directly folded, the automatic fixing and limiting can be achieved, and the coupler can be released by pulling the pull rod without needing a special tool, so that the operation can be achieved with hands, and the coupler folding and fixing operation process and procedure are greatly facilitated.

Description

technical field [0001] The invention relates to a fixing device for a rail vehicle folding coupler, and belongs to the technical field of coupler fixing suitable for rail vehicles. Background technique [0002] At present, the folding couplers configured on light rail vehicles are generally fixed to the car body by bolts and other connection methods, which is inconvenient to operate. The use of bolts requires special tools to realize opening or fixing, which is inconvenient to operate and is not conducive to the coupling of the coupler and vehicle rescue. [0003] After searching, it is found that the Chinese invention patent application CN 109455192 A discloses a folding coupler locking mechanism. A locking turret acted by a locking spring is arranged at the turning point of the coupler. Two-state lock. The mechanism is locked by a spring, and when the coupler is subjected to an external force, it is easy to overcome the elastic force of the spring and unlock, so the stab...
