Abstract
The utility model discloses a kind of Diamond-Shape Form Traveler main couple walking system for road and bridge construction, form primarily of jack (1), hydraulic jack (2), walking rails (3) and limit switch (4), described jack (1), hydraulic jack (2) are horizontally fixed on walking rails (3), jack (1) bottom is bolted on bearing (5), hydraulic jack (2) one end is fixed on jack (1) top, and limit switch (4) is positioned at walking rails (3) afterbody.This system adopts jack as walking system power set, decreases and adopts guide chain to drive generation workload, and be provided with limit switch, can limit, improve the safety of Dynamic System to walking system displacement of walking.
Description
Technical field
The utility model relates to road and bridge construction field, specifically refers to a kind of Diamond-Shape Form Traveler main couple walking system for road and bridge construction.
Background technology
Prestressed concrete continuous beam, the general span of continuous steel frame bridge are large and across rivers, river valley, mainly adopt case-in-place cantilever method.Tradition Hanging Basket utilizes beam body longitudinal prestressing finish rolling deformed bar as anchoring system, when 0# block segment length is shorter, take arranged in dislocation Hanging Basket, 1# block Duan Houzai to be onstructed is transformed into longitudinal prestressing muscle axial location, and suspended basket adopts the anchor type of left-hand thread track, in position conversion and traveling process, often easily cause security incidents such as toppling because of reasons such as misoperation, the defects of Hanging Basket system own.
Utility model content
The purpose of this utility model is to provide a kind of Diamond-Shape Form Traveler main couple walking system for road and bridge construction.This system adopts jack as walking system power set, decreases and adopts the workload brought of guide chain, and be provided with limit switch, can limit, the safety of raising Dynamic System to walking system displacement of walking.
The utility model is achieved through the following technical solutions:
A kind of Diamond-Shape Form Traveler main couple walking system for road and bridge construction, form primarily of jack, hydraulic jack, walking rails and limit switch, described jack, hydraulic jack are horizontally fixed on walking rails, be bolted on bottom jack on bearing, after Hanging Basket is in place, truss posterior nodal point Ф 32 fining twisted steel is anchored on track steel sleeper, the power that Hanging Basket rear end is born is passed to beam body, do not allow bearing inverse buckling wheel stressed, hydraulic jack one end is fixed on jack top, and limit switch is positioned at walking rails afterbody.Described limit switch is provided with switch handle.Described walking rails afterbody is fixed on main couple by anchor device.Described walking rails afterbody is provided with rear anchor wheel, and rear anchor wheel forms slide surface with sliding rail top board lower edge.After 0# section tension of prestressed tendon completes, release the suspended basket centre-line of track, attachment rail bearing beam, with cement mortar screeding under track bearing beam, walking track accurately arranges two track spaces and two groups of track spaces in one group, guarantees the spacing of main couple, and it is real to grasp plain cushion.The interorbital center to center distance of strict control is consistent with drawing.Track installation is straight, and rail top face will keep level, and the discrepancy in elevation of track is not more than 5mm.In work progress, truss is walked on walking rails, track two i iron are welded into II type cross section, under symmetry is laid on the two panels truss of case top surface of the beam, bearing is placed on before and after track, be connected with truss with pin, under front bearing, be lined with polytetrafluoroethylene (PTFE) slide plate, make it to slide along the corrosion resistant plate on track; Rear support left-hand thread edge in orbit, effect is rolled along track lower edge with inverse buckling wheel, walking rails base plate vertical prestress anchoring.
Further, for realizing the utility model better, YC75-100 Long travel jack selected by described jack.
The utility model compared with prior art, the beneficial effect had is: this system adopts jack as walking system power set, decreases the workload adopting guide chain to drive, and is provided with limit switch, can limit walking system displacement of walking, improve the safety of Dynamic System.

Detailed description of the invention
Below in conjunction with embodiment, the utility model is described in further detail, but embodiment of the present utility model is not limited thereto.
Embodiment 1:
As shown in Figure 1, a kind of Diamond-Shape Form Traveler main couple walking system for road and bridge construction, form primarily of jack 1, hydraulic jack 2, walking rails 3 and limit switch 4, jack 1, hydraulic jack 2 are horizontally fixed on walking rails 3, be bolted on bearing 5 bottom jack 1, after Hanging Basket is in place, truss posterior nodal point Ф 32 fining twisted steel is anchored on track steel sleeper, the power that Hanging Basket rear end is born is passed to beam body, do not allow bearing 5 inverse buckling wheel stressed, hydraulic jack 2 one end is fixed on jack 1 top, and limit switch 4 is positioned at walking rails 3 afterbody.Described limit switch 4 is provided with switch handle 5.Walking rails 3 afterbody is fixed on main couple by anchor device 6.Walking rails 3 afterbody is provided with rear anchor wheel, and rear anchor wheel forms slide surface with sliding rail top board lower edge.YC75-100 Long travel jack selected by jack 1.
Before construction, after 0# section tension of prestressed tendon completes, release the suspended basket centre-line of track, attachment rail bearing beam, with cement mortar screeding under track bearing beam, walking track accurately arranges two track spaces and two groups of track spaces in one group, guarantee the spacing of main couple, and it is real to grasp plain cushion.The interorbital center to center distance of strict control is consistent with drawing.Track installation is straight, and rail top face will keep level, and the discrepancy in elevation of track is not more than 5mm.In work progress, truss is walked on walking rails, track two i iron are welded into II type cross section, under symmetry is laid on the two panels truss of case top surface of the beam, bearing is placed on before and after track, be connected with truss with pin, under front bearing, be lined with polytetrafluoroethylene (PTFE) slide plate, make it to slide along the corrosion resistant plate on track; Rear support left-hand thread edge in orbit, effect is rolled along track lower edge with inverse buckling wheel, walking rails base plate vertical prestress anchoring.
The above; it is only preferred embodiment of the present utility model; not do any pro forma restriction to the utility model, every any simple modification, equivalent variations done above embodiment according to technical spirit of the present utility model, all falls within protection domain of the present utility model.
