Abstract
The invention discloses a kind of the second pontic erection method of split type level bridges, comprise the following steps：First, after having set up the first pontic, second pontic is pushed on the first pontic for having set up, second pontic in place after, one end of second pontic is connected with the first pontic, second pontic carries folding-unfolding mechanism, driven and deployed by folding-unfolding mechanism, the other end of the second pontic of control gradually decreases down to be bonded with the first pontic；2nd, the connection between the first pontic and the second pontic is released, first pontic and the second pontic are pivotally connected in side, it is then lifted out the second pontic so that the second pontic rotates relative to the first pontic, and the second pontic and the first pontic are in parallel arranged on same plane after having rotated.The second pontic erection method is very ingenious in above-mentioned erection method, and the center of gravity of the second pontic remains at relatively low position during its erection, is consumed energy when its erection can be greatly reduced.
Description
Technical field
The present invention relates to a kind of the second pontic erection method of split type level bridges.
Background technology
The fast construction bridge on river or gully is in emergency circumstances needed some, now in order to ensure that bridge is quickly taken
Build, it is general to solve the problem using split type level bridges are set up, but the erection method of existing split type level bridges is present
Some problems, for example, need to be equipped with larger counterweight, power consumption is high, sets up efficiency deficiency etc. other shortcomings, for this, the present invention carries
For a kind of the second pontic erection method of split type level bridges.
The content of the invention
In order to solve the above problems, the present invention provides a kind of second pontic erection method of split type level bridges.
The technical solution adopted for the present invention to solve the technical problems is：
A kind of second pontic erection method of split type level bridges, the split type level bridges include pedestal, one folding
First pontic and at least one foldable second pontic, it is characterised in that comprise the following steps：
First, after having set up the first pontic, the second pontic is pushed on the first pontic for having set up, the second pontic in place after,
One end of second pontic is connected with the first pontic, the second pontic carries folding-unfolding mechanism, is driven and deployed by folding-unfolding mechanism, control
The other end of second pontic gradually decreases down to be bonded with the first pontic；
2nd, the connection between the first pontic and the second pontic is released, the first pontic and the second pontic are pivotally connected in side, so
After lift the second pontic so that the second pontic rotates relative to the first pontic, and the second pontic and the first pontic are in same after having rotated
Parallel arranged in plane.
Present invention additionally comprises：
Step 3: the pontic of lifting first and the second pontic are so that erection support, completion are set up thereunder.
The pedestal is provided with winding plant, and the second pontic is pushed on the first pontic for having set up by winding plant,
The other end for controlling the second pontic by winding plant is gradually reduced.
In the step 2 after the second pontic has been overturn, the connection of the first pontic and the second pontic is released, by the second bridge
Body translates setpoint distance.
The beneficial effects of the invention are as follows：It is very low to counterweight requirements when the second pontic is set up in above-mentioned erection method, second
Pontic erection method is very ingenious, and the center of gravity of the second pontic remains at relatively low position during its erection, can be big
Width consumes energy when reducing its erection, and stability when lifting erection, has the advantages of low-energy-consumption high-efficiency.
Brief description of the drawings
The present invention is further described with reference to the accompanying drawings and examples：
Fig. 1 is the schematic diagram one of step 1 in the present invention；
Fig. 2 is the schematic diagram two of step 1 in the present invention；
Fig. 3 is the schematic diagram three of step 1 in the present invention；
Fig. 4 is the schematic diagram of step 2 in the present invention.
Embodiment
1~Fig. 4 of reference picture, the present invention are a kind of erection methods of the second pontic 4 of split type level bridges, the split type steelframe
Bridge includes pedestal 1, folding first pontic 3 and at least one foldable second pontic 4, it is characterised in that including following step
Suddenly：
First, after having set up the first pontic 3, the second pontic 4 is pushed on the first pontic 3 for having set up, the second pontic 4 is in place
Afterwards, one end of the second pontic 4 is connected with the first pontic 3, the second pontic 4 carries folding-unfolding mechanism, and exhibition is driven by folding-unfolding mechanism
Open, the other end of the second pontic 4 of control gradually decreases down to be bonded with the first pontic 3；
2nd, the connection between the first pontic 3 and the second pontic 4 is released, by the first pontic 3 and the second pontic 4 in side pivot
Connect, be then lifted out the second pontic 4 so that the second pontic 4 rotates relative to the first pontic 3, the second pontic 4 and the first bridge after having rotated
Body 3 is in parallel arranged on same plane；
Step 3: lifting the first pontic 3 and the second pontic 4 are so that erection support, completion are set up thereunder.In step 2
After the second pontic 4 has been overturn, the connection of the first pontic 3 and the second pontic 4 is released, the second pontic 4 is translated into setpoint distance.On
State in erection method very low to counterweight requirements when the second pontic 4 is set up, the erection method of the second pontic 4 is very ingenious, the second bridge
The center of gravity of body 4 remains at relatively low position during its erection, is consumed energy when its erection can be greatly reduced, and hoisting frame
If when stability, there is the advantages of low-energy-consumption high-efficiency.
As Figure 1-Figure 4, pedestal 1 is provided with winding plant 2, is pushed into set up by the second pontic 4 by winding plant 2
The first pontic 3 on, by winding plant 2 control the second pontic 4 the other end be gradually reduced.The working stability of winding plant 2, can
Carry out the control of big stroke.
Above-described embodiment is the preferred scheme of the present invention, and the present invention can also have other embodiments.The technology of this area
Personnel can also make equivalent variations or replacement on the premise of without prejudice to spirit of the invention, and these equivalent modifications or replacement are wrapped
It is contained in the scope set by the application claim.
