Specific embodiment
A kind of Liftable type steel trestle structure as shown in Figure 1, Figure 2 and Figure 3, steel is withstood on including steel trestle bridge floor 1 and branch
The bridge pier 2 of 1 lower section of trestle bridge floor further includes two symmetrical elevating mechanisms laid and be used to lift steel trestle bridge floor 1, two institutes
The front-end and back-end that elevating mechanism is laid in steel trestle bridge floor 1 respectively are stated, the elevating mechanism includes being laid in steel trestle bridge floor 1
The symmetrical volume for being laid in 4 top of hoisting frame of the hoisting frame 4 of end, the hanging beam 3 for being laid in 1 bottom of steel trestle bridge floor and two
Raise machine 5；
As shown in Figure 1, Figure 2 and Figure 3, the hoisting frame 4 includes existing along the width horizontal layout of steel trestle bridge floor 1
Branch withstands on support top mechanism below 6 left and right ends of crossbeam, two branch respectively by the crossbeam 6 of the top of steel trestle bridge floor 1 and two
Top mechanism is laid in the left side and right side of steel trestle bridge floor 1 respectively, and two support top mechanisms are symmetrically laid, each support top
Mechanism includes two and symmetrically props up the column 7 withstood below 6 front and rear sides of crossbeam, is offered on each column 7 vertical
Sliding slot 9；
As shown in Figure 1, Figure 2 and Figure 3, the hanging beam 3 is laid in the underface of crossbeam 6, and the both ends of the hanging beam 3 are fixed
Sliding block 8 is installed, the both ends of the sliding block 8 are fastened on the vertical chute 9 of two columns 7 in the same support top mechanism respectively
It is interior；
As shown in Figure 1, Figure 2 and Figure 3, two hoist engines 5 in the same elevating mechanism are symmetrically laid in described
The left and right ends of crossbeam 6, steel strand wires 10 are wound on two hoist engines 5, and the lower end of two steel strand wires 10 is perpendicular
The left and right ends that direct puncture crosses after crossbeam 6 respectively with hanging beam 3 are connected.
In the present embodiment, the sliding block 8 is horizontal layout, and the both ends of sliding block 8 are fastened on the vertical cunning of two columns 7 respectively
In slot 9, make sliding block 8 that can only move up and down, it is impossible to which left-right and front-back moves, so as to make hanging beam 3 that can only move up and down indirectly, so as to protect
It has demonstrate,proved after left and right or front and rear swing will not occur when steel trestle bridge floor 1 is lifted and ensure that steel trestle bridge floor 1 is laid down
Position will not shift, define the movement locus of steel trestle bridge floor 1, improve slinging and putting down for steel trestle bridge floor 1
Action stability.
As shown in Figure 4 and Figure 5, in the present embodiment, the cross-sectional shape of the vertical chute 9 is trapezoidal, the vertical cunning
The width of 9 notch of slot is more than the width of slot bottom.The general local environment steam of steel trestle is big, along with being raised by the vehicle of steel trestle
The dust gravel risen easily forms knot in the vertical chute 9, and the cross-sectional shape of the vertical chute 9 is trapezoidal, and vertical sliding
The width of 9 notch of slot is more than the width of slot bottom, is conducive to remove into formation knot in the vertical chute 9.
As shown in Figure 4, Figure 5 and Figure 6, the sliding block 8 is rod-shaped bloom, and the both ends of the sliding block 8 are round-like structure,
The top surface diameter of the round-like structure and being of same size for 9 slot bottom of the vertical chute, the basal diameter of the round-like structure with
9 notch of the vertical chute is of same size.
In view of that when vehicle is by steel trestle bridge floor 1, one can be applied to steel trestle bridge floor 1 and grown along steel trestle bridge floor 1
The frictional force in direction is spent, if steel trestle bridge floor 1 has the trend being moved forward or rearward, is laid in 1 bottom of steel trestle bridge floor
Hanging beam 3 consequently also has the trend being moved forward or rearward, and the end of sliding block 8 will generate thrust, institute to the vertical chute 9 at this time

Be of same size, the end face of the sliding block 8 is enable to be connected to 9 slot bottom of the vertical chute.If the end face of the sliding block 8 does not abut
In 9 slot bottom of the vertical chute, then when generating thrust to the vertical chute 9 in the end of sliding block 8, the end meeting wedging of sliding block 8 is vertical
In sliding slot 9.The both ends of the sliding block 8 are both designed as round-like structure, side and 9 side wall of the vertical chute of round-like structure connect
Contacting surface product is small, can reduce frictional force when sliding block 8 slides up and down.
When the utility model is used, when needing to raise 1 elevation of steel trestle bridge floor, while two hoisting frames 4 are opened
On four hoist engines 5, four hoist engines 5 roll steel strand wires 10 simultaneously, and hanging beam 3 is sling to moving up in the lower ends of steel strand wires 10
Dynamic, for the sliding block 8 at 3 both ends of hanging beam along 9 upward sliding of the vertical chute on column 7, hanging beam 3 drives steel trestle bridge floor 1 to move up,
After elevation needed for steel trestle bridge floor 1 is raised to, four hoist engines 5 are simultaneously stopped and roll steel strand wires 10；When needing steel
When trestle bridge floor 1 falls, four hoist engines 5 slowly discharge steel strand wires 10 simultaneously, and the sliding block 8 at 3 both ends of hanging beam is along column 7
9 slide downward of the vertical chute, hanging beam 3 and steel trestle bridge floor 1 move down, until dropped down onto under steel trestle bridge floor 1 on bridge pier 2,
Four hoist engines 5 are simultaneously stopped release steel strand wires 10.
The above is only the preferred embodiment of the utility model, not the utility model imposed any restrictions, every
Any simple modification, change and the equivalent structure made according to the utility model technical spirit to above example change, still
Belong in the protection domain of technical solutions of the utility model.
