Description
Technical field
The utility model is related to a kind of technical field of tunnel construction, particularly a kind of trestle traverse displacement unit.
Background technology
In constructing tunnel, after inverted arch construction area excavates, it is necessary to by the cross-domain construction area of trestle, in order to
Vehicle smoothly passes through.There is barrier in front of the inverted arch construction area of leap or ground is uneven so that trestle front end can not
It is steady to place, it at this moment needs by trestle move left and right so that avoiding obstacles or rugged ground are held level with both hands before making trestle
It is steady to place.
Prior art discloses a kind of trestle translating device (as shown in Figure 1), including the chassis being connected under the bridge floor of left and right,
The chassis can horizontally slip with host bridge, and support base is connected under the chassis, is connected on the outside of the main bridge in left and right
Lifting cylinder is connected with traversing oil cylinder between the bridge floor and chassis.Step need to be carried out when trestle needs to be moved to the left：
The first step, lifting cylinder shrink the liftoff support base in lifting cylinder bottom at this time and land, right side translation oil cylinder extended, left side is put down
It moves oil cylinder to shorten, the translation oil cylinder on right side promotes right main bridge to move right at this time, and the translation oil cylinder in left side pulls left main bridge to the left
It is mobile；Second, after the completion of the first step, lifting cylinder is extended, with the elongation of lifting cylinder so as to lift bridge floor, passes through bridge
Face drives chassis and support base to move up, leaving ground when support base makes fixed lifting cylinder motionless, at this time right side
The translation oil cylinder that translation oil cylinder shrinks left side extends that chassis and pedestal is driven to move right.Repeating the above steps can realize
To the mobile over long distances to the left of trestle.Similarly, can also realize to the mobile over long distances to the right of trestle.
Although the prior art can be realized and trestle is moved left and right, carry out when trestle moves left and right, it is necessary to use a left side
Right lifting cylinder all lifts the main bridge in left and right and chassis and support base.Chassis and support base are made and again using steel
Measure heavier, in order to which the main bridge in left and right and chassis and support base are lifted simultaneously, left and right lifting cylinder need to use larger rule
The oil cylinder of lattice, so as to add equipment cost.Secondly, main bridge divides into bottom set frame and so that the structure of trestle is more complicated, increases
To the difficulty of trestle regular maintenance.
Utility model content
The goal of the invention of the utility model is：For in existing trestle mobile device, the existing above problem provides one
Kind traverse displacement unit.
To achieve these goals, the technical solution adopted in the utility model is：
A kind of trestle traverse displacement unit is slip between the connecting rod and main bridge including the connecting rod being arranged under main bridge
Connection, is connected with translation mechanism between the connecting rod and main bridge, described translation mechanism one end is connected to main bridge, other end connection
In connecting rod, the connecting rod both ends are connected with elevating mechanism.
It is followed the steps below when trestle needs to move right：The first step, elevating mechanism are shunk, due to before main bridge at this time
Both ends are overlapped on the ground as stationary state afterwards, therefore on main bridge and connecting rod will not occur when elevating mechanism is shunk
Lower movement is left ground after-contraction when elevating mechanism bottom and is stopped；Second step, opening translation mechanism makes connecting rod drive elevator
Structure moves right together, when move right suitable distance after translation mechanism stop motion, at this time extend elevating mechanism make elevator
Structure bottom is contacted with ground；3rd step, elevating mechanism continue elongation until main bridge rear and front end is risen to leave ground after stop
Rise, connecting rod and elevating mechanism remain stationary as at this time, open translation mechanism and main bridge moves right, Dang Zhuqiao moves right suitable
When apart from after translation mechanism stop motion, elevating mechanism contraction at this time makes main bridge drop to rear and front end and ground to be in close contact.
Repeating appeal step can realize that trestle moves right over long distances, similarly, can also realize and trestle is moved to the left over long distances.
