Description

TECHNICAL FIELD

[0001] The utility model relates to rail transit technical field, concretely is a kind of eccentric support type guard rail. BACKGROUND

[0002] Guard rail refers to the steel rail that is laid on the inner side of the steel rail on the track and does not bear the vertical load of the wheel. According to the laying location, it has different functions. The guard rail at the turnout frog is laid on the inner side of the steel rail opposite to the harmful space of the frog, guides the wheel to pass through the harmful space, and avoids hitting the tip of the frog. The guard rail on the bridge can prevent the derailed vehicle from hitting the bridge or falling under the bridge. The guard rail laid on the inner side of the inner rail on the small radius curve can reduce the side wear of the outer rail. The anti-derailment guard rail is a auxiliary rail installed on the inner side of the railway line. The anti-derailment guard rail has the functions of ensuring the safety of train operation and preventing train derailment, and is a safety device for preventing train derailment. According to the search, the patent with publication number CN115491934A discloses a shock-absorbing and noise-reducing guard rail device for vehicles passing through a small-radius curve section. The support screw part under the I-beam guard rail is further sleeved with a conical elastic block. The lower end surface of the conical elastic block is in contact with the head of the "J"-shaped guard rail support, and the upper end surface of the conical elastic block is in contact with the lower surface of the middle connecting part of the I-beam guard rail. The taper of the conical elastic block is the same as the slope of the I-beam guard rail, so that the side surface of the conical elastic block is exactly clamped in the groove of the I-beam guard rail. Then, the "J"-shaped guard rail support is pressed tightly by the double locking nuts, so that a kind of elastic fixation is formed under the I-beam guard rail. However, the preparation of the conical elastic block not only requires fine adjustment of the height during installation, but also makes the guard rail prone to height instability during installation. Moreover, multiple conical elastic blocks need to be placed along the length in the reverse direction, which is prone to falling off during installation, and the overall stability is poor. Therefore, an eccentric support type anti-derailment guard rail is designed, which is convenient to install and not easy to fall off, and the installation height is kept constant.
