Abstract
The utility model discloses a telescopic hoisting gantry crane used for paving unballasted tracks. The gantry crane mainly comprises a mother beam, a gantry crane supporting leg, a child beam, a winch, a hanger plate trolley, a wire rope, guide pulleys, an upper PTFE (polytetrafluoroethylene) sheet, and a lower PTFE sheet, wherein, the gantry crane supporting leg is arranged at the lower end of the mother beam; the child beam is arranged in the mother beam; the upper and the lower PTFE sheets are respectively arranged between the upper end and the lower end of the child beam contact with the mother beam; the winch is arranged at the central part of the upper end of the mother beam; the hanger plate trolley is arranged on the child beam; the wire rope bypassing the winch is connected and fixed with the child beam through the two guide pulleys; and when the winch rotates after being started, the child beam can be driven to slide in the mother beam through the wire rope. Therefore, the motion range of the hanger plate trolley can be greatly increased, and the gantry crane can conveniently conduct hoisting construction within restricted construction areas.
Description
Technical field
The utility model relates to a kind of telescoping hoisting door-hanging of the non-fragment orbit that is used to mat formation, and belongs to the railway construction machine apparatus field.
Background technology
At present, at home in the work progress of railway line for passenger traffic and high speed railway, employing be fragment-free track slab.About about 8 tons of this track plate weight need be processed in specific making sheet field.In concrete construction and installation process, if carrying the plate machine with cross-line installs to this track plate on the desired location from carrying to bridge under the bridge, repaving, must guarantee that then the road surface of both sides under the bridge keeps smooth, this engineering is expensive bigger.If directly the track plate is winched on the bridge under bridge with hanging device, hanging device is by construction restricted areass such as tunnel or electric poles the time so, must carry out dismounting to hanging device, after moving to suitable position, carry out lifting construction again, so not only can have a strong impact on the efficient of construction of railways, also increased simultaneously working strength of workers, so existing hanging device uses very inconvenient, brings many worries to unit in charge of construction.
The utility model content
The purpose of this utility model is to design the telescoping hoisting door-hanging that a kind of non-fragment orbit that is used to mat formation is provided at the problems referred to above, this hoisting door-hanging is by the extension function of the inner sub-beam of its female beam, can directly under bridge, lift the track plate, and when by construction restricted areass such as tunnel or electric poles the time, need not dismantle gantry crane equipment, as long as the inner extended sub-beam of female beam is partly regained in female beam, promptly is movable to predetermined appropriate position and carries out lifting construction work.This gantry crane equipment can reduce working strength of workers, reduces the waste of manpower, material and fund, improves construction speed and efficient.
In order to achieve the above object, the utility model is realized by following technological means.
The telescoping hoisting door-hanging of non-fragment orbit is used to mat formation, it mainly is made of female beam, gantry crane supporting leg, Zi Liang, winch, boatswain chair dolly, steel rope, leading sheave, upper strata tetrafluoro plate, lower floor's tetrafluoro board main portion, wherein: be provided with the gantry crane supporting leg in the installation of the lower end of female beam, in female beam, be provided with sub-beam, between sub-beam and the contacted top and bottom of female beam, be respectively arranged with upper strata tetrafluoro plate and lower floor's tetrafluoro plate, mainly play the effect that reduces to rub; Upper center at female beam is provided with winch, and Zi Liang is provided with the boatswain chair dolly; After steel rope is walked around winch, be connected and fixed by two leading sheaves and Zi Liang; When winch starts the back rotation, can in female beam, slide by rope belt mover beam, like this, the action radius of boatswain chair dolly can increase a lot, can carry out lifting construction very easily at the construction area that is restricted.
Described winch is the friction-type winch.
When hoisting door-hanging need carry out whole when mobile at construction restricted areass such as tunnel, electric poles, as long as sub-beam is retracted in female beam by the control winch, like this, can dwindle the length of whole gantry crane equipment, make gantry crane equipment pass through restricted areas smoothly, move to predetermined place easily and carry out construction operation.
The utility model mainly has following beneficial effect:
This hoisting door-hanging is by the extension function of the inner sub-beam of its female beam, can directly under bridge, lift the track plate, and when by construction restricted areass such as tunnel or electric poles the time, need not dismantle gantry crane equipment, as long as the inner extended sub-beam of female beam is partly regained in female beam, promptly is movable to predetermined appropriate position and carries out lifting construction work.This gantry crane equipment can reduce working strength of workers, reduces the waste of manpower, material and fund, improves construction speed and efficient.
Description of drawings
Accompanying drawing 1 is the planar structure scheme drawing of the utility model telescoping hoisting door-hanging equipment;
Accompanying drawing 2 is the vertical section structure scheme drawings after the sub-beam 2 of the utility model telescoping hoisting door-hanging equipment inserts in female beam 3.
As shown in the figure, each structure division of above-mentioned telescoping hoisting door-hanging equipment is represented by following Arabic number:
1. boatswain chair dolly, 2. sub-beam, 3. female beam, 4. winch, 5. gantry crane supporting leg, 6. steel rope, 7. leading sheave, 8. upper strata tetrafluoro plate, 9. lower floor's tetrafluoro plate.

The specific embodiment
Embodiment
As shown in Figure 1, the telescoping hoisting door-hanging of the non-fragment orbit that is used to mat formation, it mainly is made of female beam 3, gantry crane supporting leg 5, sub-beam 2, winch 4, boatswain chair dolly 1, steel rope 6, leading sheave 7, upper strata tetrafluoro plate 8, lower floor's tetrafluoro plate 9 main portions.
As shown in Figure 1, be provided with gantry crane supporting leg 5, in female beam 3, be provided with sub-beam 2 in the installation of the lower end of female beam 3.
As shown in Figure 2, between sub-beam 2 and female beam 3 contacted top and bottom, be respectively arranged with upper strata tetrafluoro plate 8 and lower floor's tetrafluoro plate 9, mainly play the effect that reduces to rub.
As shown in Figure 1 and Figure 2, be provided with winch 4 in the upper center of female beam 3, sub-beam 2 is provided with boatswain chair dolly 1; After steel rope 6 is walked around winch 4, be connected and fixed by two leading sheaves 7 and sub-beam 2; When winch 4 starts the back rotation, can drive sub-beam 2 by steel rope 6 and in female beam 3, slide, like this, the action radius of boatswain chair dolly 1 can increase a lot, can carry out lifting construction very easily at the construction area that is restricted.
