Referring to fig. 1-5, a pedal device for a cab of a rail vehicle provided in an embodiment of the present application includes a frame 1, a pedal 2, and a lock; the framework 1 is movably hinged with the pedal 2 on one hand, and is fixedly connected with the pedal 2 through a lock on the other hand.

This application embodiment provides a new connected mode for footboard 2 and skeleton 1, with the combination of articulated connected mode and lock connected mode, replaces bolt fixed connection mode among the prior art, has solved 2 dismantlements of footboard, the inconvenient problem of installation that bolt fixed connection mode brought, realizes footboard 2 and opens and shuts fast on skeleton 1.

As shown in fig. 1, in the present embodiment, the framework 1 includes two side guards 11, which are oppositely disposed, and are a first side guard and a second side guard respectively; the pedal 2 is transversely arranged between the first side baffle and the second side baffle; the framework 1 further comprises a supporting plate 12 arranged below the pedal 2 and used for supporting the pedal 2. The supporting plate 12 comprises a first supporting plate and a second supporting plate which are symmetrically arranged; the first supporting plate is fixedly connected with the first side baffle, and the second supporting plate is fixedly connected with the second side baffle.

In this embodiment, a buffer layer is disposed on the surface of the stay plate 12 contacting the pedal 2, and the buffer layer is made of rubber. When footboard 2 is in the abnormal time down that drops of open mode, the rubber buffer layer can play the cushioning effect, avoids haring footboard 2 and fagging 12.

In this embodiment, the lock is a compression type square lock 3, the compression type square lock 3 includes a lock tongue 31 and a lock catch plate 32, the lock tongue 31 is disposed on the pedal 2, and the lock catch plate 32 is disposed on the supporting plate 12 nearest to the lock tongue 31. In other embodiments, the lock plate 32 may be disposed on the pedal 2, and the latch 31 may be disposed on the support plate 12 closest to the lock plate 32.

The compression type square lock 3 is compact in structure, extremely suitable for occasions with limited space, namely pedals, and is installed only through a single hole, so that the installation is quicker. Of course, in other embodiments, other types of locks may be used. The working principle of the pedal device provided by the embodiment of the application is as follows:

when the pedal 2 is at the lowest position, namely the pedal 2 presses on the buffer layer of the supporting plate 12, the key of the compression type square lock 3 is rotated, the bolt 31 rotates towards the direction of the lock catch plate 32, as shown in a in fig. 5, when the bolt 31 starts to contact and is lapped on the lock catch plate 32, the compression type square lock 3 starts to compress and drives the pedal 2 to compress the buffer layer downwards, so that the pedal 2 is locked, and when the bolt 31 is completely lapped on the lock catch plate 32, the compression type square lock 3 is completely compressed, and the pedal 2 is in a closed state;

when the key of the compression type square lock 3 is rotated in the reverse direction, the locking tongue 31 is rotated away from the locking plate 32, as shown in b of fig. 5, when the locking tongue 31 is completely separated from the locking plate 32, the compression type square lock 3 is returned, the pedal 2 is in an unlocked state, the pedal 2 is operated upward by hand, the pedal 2 can be rotated around the axis of the hinge 5, and thus the pedal 2 is opened.

In this embodiment, the number of the compression type square locks 3 is 2, and the compression type square locks are respectively used for locking the pedal 2 and the first supporting plate, and locking the pedal 2 and the second supporting plate, so that the two sides of the pedal 2 are locked more stably. Of course, the number of the compression type square locks 3 can be increased, but preferably, 2 compression type square locks are arranged, so that the pedal 2 can be stably locked and the operation is convenient.

In the embodiment, a transverse connecting plate 13 is arranged between the first side baffle and the second side baffle, and the transverse connecting plate 13 is hinged with the pedal 2; the number of the hinges 5 is 2, and the rotation centers of the 2 hinges 5 are on a straight line. In other specific embodiments, the hinged articulation may be replaced by a bearing articulation.

The pedal 2 is provided with a pedal switch 4, and in the embodiment, the pedal switch 4 includes: a sanding switch, an unmanned alarm switch and a bass whistle switch.
