Abstract
The invention discloses the second pontic erection method of a kind of split type level bridges, comprise the following steps: after one, having set up the first pontic, second pontic is pushed on the first pontic set up, after second pontic puts in place, one end of second pontic is connected with the first pontic, second pontic carries folding-unfolding mechanism, is driven by folding-unfolding mechanism and launches, and the other end controlling the second pontic gradually decreases down and the first pontic laminating；Two, release the connection between the first pontic and the second pontic, by the first pontic and the second pontic in side pivot joint, be then lifted out the second pontic so that the second pontic rotates relative to the first pontic, now the second pontic and the first pontic parallel arranged on same plane.In above-mentioned erection method, the second pontic erection method is the most ingenious, and the center of gravity of the second pontic remains at relatively low position during it sets up, and when it set up power consumption can be greatly reduced.
Description
Technical field
The present invention relates to the second pontic erection method of a kind of split type level bridges.
Background technology
Fast construction bridge on river or gully is in emergency circumstances needed, now in order to ensure that bridge is quickly taken at some
Building, general employing sets up split type level bridges and solves this problem, but the erection method of existing split type level bridges exists
Some problems, such as need to be equipped with bigger counterweight, consume energy high, set up efficiency other shortcoming not enough etc., carry for this present invention
The second pontic erection method for a kind of split type level bridges.
Summary of the invention
In order to solve the problems referred to above, the present invention provides the second pontic erection method of a kind 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, this split type level bridges include pedestal, one folding first
Pontic and at least one collapsible second pontic, it is characterised in that comprise the following steps:
One, after having set up the first pontic, the second pontic is pushed on the first pontic set up, after the second pontic puts in place, by
One end of two pontics is connected with the first pontic, and the second pontic carries folding-unfolding mechanism, is driven by folding-unfolding mechanism and launches, controls second
The other end of pontic gradually decreases down and the first pontic laminating；
Two, release the connection between the first pontic and the second pontic, by the first pontic and the second pontic in side pivot joint, then carry
Rise the second pontic so that the second pontic rotates relative to the first pontic, now the second pontic and the first pontic on same plane also
Row arrangement.
Present invention additionally comprises:
Step 3, lifting the first pontic and the second pontic, so that thereunder erection support, complete to set up.
Described pedestal is provided with winding plant, is pushed on the first pontic set up by the second pontic by winding plant,
The other end being controlled the second pontic by winding plant is gradually reduced.
In described step 2 after the second pontic has overturn, release the first pontic and the connection of the second pontic, by the second bridge
Body translation setpoint distance.
The invention has the beneficial effects as follows: in above-mentioned erection method, the second pontic is the lowest to counterweight requirements when setting up, second
Pontic erection method is the most ingenious, and the center of gravity of the second pontic remains at relatively low position during it sets up, can be big
Width reduces power consumption when it sets up, and stability when promoting erection, the advantage with low-energy-consumption high-efficiency.
Accompanying drawing explanation
The present invention is further described with embodiment below in conjunction with the accompanying drawings:
Fig. 1 is the schematic diagram one of step one in the present invention；
Fig. 2 is the schematic diagram two of step one in the present invention；
Fig. 3 is the schematic diagram three of step one in the present invention；
Fig. 4 is the schematic diagram of step 2 in the present invention.
Detailed description of the invention
With reference to Fig. 1～Fig. 4, the present invention is the second pontic 4 erection method of a kind of split type level bridges, this split type steelframe
Bridge includes folding first pontic 3 and at least one collapsible second pontic 4 of pedestal 1, it is characterised in that include following step
Rapid:
One, after having set up the first pontic 3, the second pontic 4 is pushed on the first pontic 3 set up, after the second pontic 4 puts in place,
Being connected with the first pontic 3 one end of second pontic 4, the second pontic 4 carries folding-unfolding mechanism, is driven by folding-unfolding mechanism and launches,
Control the other end of the second pontic 4 to gradually decrease down and fit with the first pontic 3；
Two, 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 joint, so
Rear lifting the second pontic 4 so that the second pontic 4 rotates relative to the first pontic 3, now the second pontic 4 and the first pontic 3 are in same
Parallel arranged in plane；
Step 3, lifting the first pontic 3 and the second pontic 4, so that thereunder erection support, complete to set up.In step 2
After two pontics 4 have overturn, release the first pontic 3 and connection of the second pontic 4, the second pontic 4 is translated setpoint distance.Above-mentioned frame
In equipment, method, the second pontic 4 is the lowest to counterweight requirements when setting up, and the second pontic 4 erection method is the most ingenious, the second pontic 4
Center of gravity remains at relatively low position during it sets up, and when it set up power consumption can be greatly reduced, and when promoting erection
Stability, the advantage with low-energy-consumption high-efficiency.
As Figure 1-Figure 4, pedestal 1 is provided with winding plant 2, is pushed into by the second pontic 4 by winding plant 2 and sets up
The first pontic 3 on, the other end being controlled the second pontic 4 by winding plant 2 is gradually reduced.Winding plant 2 working stability, can
Carry out the control of big stroke.
Above-described embodiment is the preferred version of the present invention, and the present invention also can have other embodiments.The technology of this area
Personnel also can make equivalent variations or replacement on the premise of spirit of the present invention, and modification or the replacement of these equivalents are all wrapped
It is contained in the scope set by the application claim.
