Specific embodiment
A kind of embodiment of the 1-6 descriptions present invention below in conjunction with the accompanying drawings.
For the removable support of urban steel bridges beam installation, there is mobile stent 1 and be installed in the middle part of mobile 1 bottom surface of stent
Thrustor, the thrustor includes jacking oil overhold 3 and horizontal pushing tow oil overhold 4, and mobile 1 bottom surface of stent is equipped with levelling
Support device and Steel Bridge are arranged on the head piece 9 of mobile 1 upper end of stent, the piston rod end of 3 upper end of the jacking oil overhold with
Mobile 1 bottom surface of stent is fixedly connected with and jacks the upper plane that movable plate 5 is fixed in 3 lower end of oil overhold, and the movable plate 5 is with being located at it
The fixed plate 6 of lower section is slidably connected, and the horizontal pushing tow oil overhold 4 is horizontally installed to 6 one end of fixed plate and horizontal push oil overhold 4 is lived
Stopper rod end with jacking oil overhold 3 be fixedly connected, the horizontal pushing tow oil overhold 4, jacking oil overhold 3 and levelling support device with control
By steel after system connects and passes through control system controlled level pushing tow oil overhold 4, jacking oil overhold 3 and levelling support device cooperate
Bridge pushes to the design and installation position of Steel Bridge;Specifically, the levelling support device is multiple levelling oil cylinder 7 and multiple looks for
Flat oil cylinder 7 is distributed in mobile 1 bottom surface of stent and outside thrustor, and the piston rod end of levelling 7 upper end of oil cylinder is consolidated
It is placed on ground, and passes through after control system controls levelling oil cylinder 7 flexible due to mobile 1 bottom surface of stent and 7 lower end of levelling oil cylinder
It realizes horizontal pushing tow oil overhold 4 and jacks the retracted for clearance of 3 piston rod of oil overhold, horizontal pushing tow oil overhold 4 is promoted with jacking oil overhold 3 and moved
To the mobile support of stent 1 and Automatic Levelling function during the translation of stent 1;Specifically, in the middle part of 1 bottom surface of mobile stent at least
Include two jacking oil overholds 3 equipped with two groups of thrustors and every group of thrustor, horizontal push 4 piston rod end of oil overhold with
The jacking oil overhold 3 of corresponding position is fixedly connected;Specifically, 1 bottom surface of mobile stent is fixedly arranged in the middle of connecting plate 8 and jacks
The piston rod end of 3 upper end of oil overhold is fixedly connected with connecting plate 8;Specifically, the mobile stent 1 for groined type steel frame construction and
Mobile stent 1 includes column 2, head piece 9 and lower supporter 10, be equipped between the head piece 9 and lower supporter 10 more root posts 2 and
Removable between adjacent upright posts 2 to be fixed with multiple bracing pieces 11, the column 2 forms for more piece connecting-rods with constant lengh detachable connection.
In walking process is pushed, first, after the piston rod elongation of control system control jacking oil overhold 3, by mobile stent 1
Stop after the height identical with jacking 3 piston rod stroke of oil overhold with being moved on the Steel Bridge on mobile stent 1, at this point, levelling oil
The piston rod of cylinder 7 is in contraction state and levelling oil cylinder 7 exist afterwards between ground as mobile stent 1 moves up it is certain away from
From as shown in Figure 3;Then, control system controlled level pushing tow oil overhold 4 piston rod elongation after promote jacking oil overhold 3 and with top
The mobile stent 1 for rising the connection of 3 piston rod end of oil overhold moves right, and is moved to identical with horizontal 4 piston rod stroke of pushing tow oil overhold
Length after stop, as shown in Figure 4;Subsequently, control system controls levelling oil cylinder 7 to work, the piston rod elongation of levelling oil cylinder 7
Afterwards, after the Steel Bridge support on mobile stent 1 and mobile stent 1, will jack the piston rod of oil overhold 3 and horizontal pushing tow oil overhold 4 according to
Secondary retracted for clearance, at this point, thrustor is away from ground a certain distance, as shown in Figure 5 and Figure 6;Finally, levelling 7 piston rod of oil cylinder
After retracted for clearance, the piston rod of levelling oil cylinder 7, jacking oil overhold 3 and horizontal pushing tow oil overhold 4 is in contraction state, recovers initial
Position, as shown in Fig. 2, afterwards, repeating the above steps until Steel Bridge to be pushed to the design and installation position of Steel Bridge.
In the technical program, mobile 1 superstructure of stent uses " groined type " structure, using standard fixed-length section bar column, respectively
Nodal pattern material column upper and lower side detachable connection can promote height that the height of mobile stent 1 is adjusted according to Steel Bridge, be applicable in
It is used in the Steel Bridge of different push height, facade, the horizontal plane of mobile stent 1 are connected using detachable angle bar, and top is set
Head piece 9,2 lower part of column are connected using heel slab with lower supporter 10, have improved bearing load, and levelling oil cylinder 7 can at least be set
Four, and mobile 1 bottom four corners of stent are connected to, while levelling oil cylinder 7 is connected with control system, control system is according to ground feelings
Condition controls levelling 7 Automatic Levelling of oil cylinder, and the piston rod stroke of the levelling oil cylinder 7 of physical features lowest part stretches out maximum, the mobile branch of guarantee
The horizontal throw of frame 1, using the walking type pushing device at 1 middle part of levelling oil cylinder 7 and mobile stent, i.e., the pushing tow dress in this document
It puts, makes Steel Bridge installation is mobile to stablize, safety coefficient is high.
The technical program sets levelling support device on the basis of incremental launching method, in mobile frame bottom, is by control
Steel Bridge is pushed to the design and installation position of Steel Bridge by the levelling support device of system control and thrustor after cooperating, cancelled
The auxiliary supports such as guide beam, Temporary Piers solve the problems, such as blocked road when urban road installs Steel Bridge, influence traffic,
Construction land tenure and large-scale crane cost are saved, being realized using levelling support device and thrustor will mobile stent 1 and mobile branch
Steel Bridge pushing tow on frame 1 is moved to the design and installation position of Steel Bridge, compared to traditional pushing tow technology, has safe, top
The characteristics of steady, axis trimming facilitates is bulldozed, in entire pushing tow moving process, since movable plate 5 and fixed plate 6 are slidably connected,
So that thrustor, during mobile stent 1 is promoted, sliding surface is between movable plate 5 and fixed plate 6, between category equipment
Internal force to steel bridge girder construction almost without damage, improves the structure stress of traditional bridge and bridge pier, simple in structure, design is new
Grain husk, it is easy to operate, the influence of Steel Bridge road pavement traffic in moving process is effectively prevented, Steel Bridge installation is mobile to stablize,
Safety coefficient is high, and push installation effectiveness is high, has higher application value.
Above-described embodiment, simply presently preferred embodiments of the present invention, is not used for limiting the scope of the present invention, therefore all with this
The equivalence changes that content described in invention claim is done should all be included within scope of the invention as claimed.
