Technical Field
The utility model belongs to track structural design field especially relates to an anti-icing box track roof beam suitable for straddle-type monorail car.
Background
Icing on the rail surface of the straddle type monorail car is a worldwide problem and is not solved by a good scheme at present. According to the experience of the actual project, the rail is frozen into two types, the first type is that after one night, a layer of thick ice which is thicker and is stuck with the rail surface is arranged on the rail surface, and the ice is characterized by high hardness, thick ice layer and is stuck with the rail into a whole, and the ice is difficult to knock out by a hammer. The second is that after the ice on the rail surface is removed, the weather is wet and cold, and after a few minutes, a very thin ice layer is formed on the rail surface immediately. For vehicles, as long as there is ice on the rail surface, the consequence is a rapid drop in the adhesion coefficient, resulting in a slippery runaway.
The existing box-shaped track beam only has an anti-icing and temperature control scheme for the track of a turnout part, and a long-distance heating method for the box-shaped track beam is not adopted, so that the icing of the track beam is prevented. The prior art is small in the area for heating the track beam and cannot meet the requirement of preventing the track beam from being frozen when being heated for a long distance.
SUMMERY OF THE UTILITY MODEL
In order to solve among the background art track roof beam heating region little, can't satisfy the anti-icing problem of long distance heating, the utility model provides an anti-icing box track roof beam solves under low temperature environment, and the box track roof beam freezes easily to lead to the condition that the stall can't move of skidding the vehicle.
The technical solution of the utility model is that:
an anti-icing box-shaped track beam comprises a track beam cross beam and a track beam vertical beam which are arranged in a T shape; heating cables are arranged at the joint of the track beam cross beam and the track beam vertical beam, the heating cables are laid along the track and the track beam cross beam, and the heating cables are fixed with the track beam through a fixing support.
The fixed bolster is L shape, and the fixed bolster both ends are respectively in track roof beam crossbeam and track roof beam vertical beam connection.
The outer side of the heating cable is provided with a heat insulation layer which is made of other heat insulation materials such as tinfoil paper or heat insulation cotton.
The track beam is provided with a plurality of temperature sensors at intervals of 300-500 m.
The temperature sensors are all connected with temperature control switches, and the temperature control switches have a remote control function.
The heating cable is arranged in a sleeve, the sleeve is connected with the track beam and the fixed bracket,
the sleeve is a split sleeve formed by combining two semicircular pipes, and the semicircular pipes are buckled through buckles.
Silica gel is uniformly filled on the joint surface of the sleeve and the track beam.
The fixing brackets are arranged one by one at intervals of 200 mm.
The utility model has the advantages that:
the heating cable can automatically generate heat after being electrified, the track is indirectly heated through heat radiation, the temperature of the heating cable can reach 70 ℃ after being electrified, the heat of the heating cable can be rapidly transmitted to the track beam in a heat radiation mode under a low-temperature environment, the temperature of the track steel beam can be kept to be rapidly increased, and therefore rainwater on the track surface is prevented from freezing; the heating condition of the track can be monitored in real time by the arrangement of the temperature sensor. Meanwhile, the corrosion-resistant coating of the rail steel beam and the like can be prevented from being damaged due to overhigh temperature. Heating cable sets up in the sleeve pipe, and the sleeve pipe is connected with track roof beam and fixed bolster, can guarantee heating cable's stability like this to the sleeve pipe adopts the mode of two semicircle locks, convenient dismantlement, and wholeness can be good.
