Description
Technical field
The utility model relates to a kind of lifting gear, specifically a kind of railway sound barrier lifter.
Background technology
In recent years; Along with putting into operation successively of China Express Railway, intercity high ferro and Line for Passenger Transportation; The noise that is produced between the wheel track when moving for reducing EMU brings harm to the resident; So the circuit both sides passing through city, suburb and village along the line all are provided with a large amount of sound barriers, with decay and prevention propagation of noise.The sound barrier single-unit is of a size of 2000 * 500 * 70mm, and quality is about 35kg, and the side, two ends is installed on up and down in the groove of the i iron column that is welded with steel plate after reaching and sealing with rubber strip up and down successively.The basis of i iron column is divided into two kinds: a kind of basis is a concrete foundation, and set bolt is the built-in fitting mode, and each bolt with two M22 of the inside and outside both sides of column bottom is connected with basic fixed; Another kind of basis be an opening standard channel-section steel up, and column is welded on the channel-section steel, whenever welds a cross-arm across a certain distance bottom the channel-section steel, inside and outside the cross-arm two ends with bolton on the basis.The height of the sound barrier of different track sections is also inequality, and general track section height is that 5 single-units are superimposed as 2500mm, and individual line section height is 7 single-unit stack written treaty 3500mm (single-unit on top is the transparent mode single-unit).
The high ferro circuit generally all adopts the overhead mode of bridge, and sound barrier is in the outermost edge of bridge.The high ferro circuit is through the operation of certain hour; Because bridge constantly produces vibration and sound barrier constantly receives wind effect; Just possibly cause the hold-down nut of sound barrier column or cross-arm to take place to become flexible even come off; Perhaps the weld at column and channel-section steel cracks, thereby the potential safety hazard of burying possibly cause serious driving accident and personal injury.Therefore, sound barrier column hold-down nut or weld must be made regular check on.And sound barrier is nontransparent barrier, and height is between 2500-3500mm, and gross mass is between 175-245kg, and this just brings very big difficulty for inspection, two fastening bolts in the maintenance sound barrier outside or weld state.
The utility model content
