It is connected.
2. working principle
In the specific use process, the voltage that it is 220V that the controller 5, which first has to after accessing decompression from railway contact line,
Then a staff opens the lock case 25 with key, closes lock, adjusts iron according to the fault type that railway bridge is occurred
Road and bridge height.As illustrated in figures 1 and 8, if it is the irregularity between each bridge floor, then the rising button 26, the electricity are pressed
Motivation 12, which is powered, to be rotated forward, and is successively passed through the shaft coupling 2 11, the retarder 10, the shaft coupling 1, the worm screw 7, is driven
It moves the rotary body 13 to rotate forward, another staff observes the graduation mark on the bracket 1, when the lifting body 2
Appropriate location is risen to along the column rail 1 and the column rail 2 15 with the connector of the improvement top cap 1, is unclamped on described
Button 26 is risen, the motor 12 stops rotating forward；If it is the irregularity between railway bridge inlet and bridge floor, then press described
Declines button 27, the motor 12, which is powered, to be inverted, and successively passes through the shaft coupling 2 11, the retarder 10, the shaft coupling
Device 1, the worm screw 7 drive the rotary body 13 to invert, and another staff observes the graduation mark on the bracket 1,
When the connector of the lifting body 2 and the improvement top cap 1 drops to appropriate position along the column rail 1 and the column rail 2 15
It sets, unclamps the declines button 27, the motor 12 stops reversion.If not regulating railway bridge height, Ke Yijin once
Row repeatedly above two operation finally pulls open lock, locks the lock case 25 until adjusting railway bridge height.
As shown in fig. 7, the column rail 1 and the column rail 2 15 are for the lifting body 2 and the improvement top cap 1
Connector plays the guiding role of rise and fall；The pier shaft 16 is whole to play a supportive role；The circular cone cushion cap 17 is more typical
Rectangular cushion cap can increase the earthing volume on cushion cap surface, improve the stability of the improvement pier body 4, and then increase Novel iron
The reliability of road lifting bridge pier；The safety door 18 can prevent non-working person from climbing novel railway lifting bridge pier；The foot
Ladder 19 helps maintenance personal to rise to 16 upper side of pier shaft；The protective fence 20 can prevent maintenance personal from surprisingly falling
It falls.
As Figure 8-9, bracket 1 and bracket 28, which play the worm screw 7, supports and fixes；The retarder
10 can reduce the input speed of the motor 12, can make the motor 12 that the rotary body 13 be driven to carry out indirectly low
The positive and negative rotation movement of fast heavy duty；The structure design that the worm gear part of the rotary body 13 is meshed with the worm screw 7, can make institute
It states rotary body 13 and realizes self-locking, i.e., the described rotary body 13 will not be under the external force of other (other than the motor 12)
It rotates.
In conclusion the utility model the utility model is designed reasonably, good reliability is easy to operate, can effectively solve
Certainly railway bridge is under the influence of various factors, bridge floor occurs between each bridge floor caused by sedimentation or protrusion, railway bridge inlet with
Longitudinal irregularity problem between bridge floor, to guarantee that train is safe, steady, high speed by railway bridge, before there is good application
Scape.
