By adopting the two-way extension gliding beam, the time from extending state to retracting state is shortened; the pillar with a contact net can be retracted and evaded from a underbridge hoisting track plate; the operation and the control are simple and reliable.
Description
Technical field
The utility model is a kind of gantry crane that is used for the high speed railway construction, particularly a kind of used for high-speed railway cross-line bed board gantry crane, can run on preferably on the intervallum between double track railway concrete bed both sides and the crashproof wall, by telescopic arm and the traveling dolly on it taken, can be from goods and materials such as the lifting of the both sides under bridge track plate, reinforcing bars.
Background technology
Along with the development of railway cause, the Infrastructure of railway and construction method have all had corresponding raising.At present, the construction of high speed railway, the construction method that adopts two-wire to advance side by side usually.Therefore, on roadbed, build two parallel concrete beds during construction, constitute an intervallum between the base, not the waiting of intervallum apart from 1.8m, 2.0m, 2.2m, 2.4m; On concrete bed, lay the track plate then, will carry out CA mortar jar between track plate and the base and annotate, at last steel rail laying on the track plate.Implement in the above-mentioned steps, laying the track plate on concrete bed is a very important operation.During the laid rail guidance tape, a very important job is how work-site to be arrived in the handling of track plate.The handling of current track plate is to adopt the cross-line gauntry crane, and this gantry crane is across the both sides of two concrete beds, uses the air-inflation tyre traveling, and the crossbeam at gantry crane top is provided with the traveling dolly, is provided with suspender below the traveling dolly.During if on bridge floor, construct, for can be from hoisting heavy under the bridge, the two ends of door frame crossbeam just must extend outward 5～6 meters cantilever, though can finish hoisting heavy under the bridge like this, but because of cantilever can not auto-folder and Telescopic, so on by the bridge floor that installs the electrified contacting nets pillar time, cantilever partly need be pulled down withdrawal, also need said method when entering the tunnel, thereby increased the difficulty of construction period and crossing ability.
Summary of the invention
In view of the above-mentioned state of the art, the purpose of this utility model provides a kind of used for high-speed railway cross-line bed board gantry crane, makes its cantilever partly have Telescopic, can escape the contact system bar easily, and pass through tunnel smoothly.
For realizing above-mentioned technical purpose, the used for high-speed railway cross-line bed board gantry crane that the utility model provides comprises supporting leg bottom installation running mechanism; The cantilever of support beam and installation is equipped with at its top, on this cantilever dolly is set; Wherein cantilever is the slippage beam of two box-beam structures, and this slippage beam upper and lower side and the interior activity of slide block that is arranged between the support beam upper and lower side are installed; The tooth bar engagement of motor reducer by gear of output end and slippage beam side direction is installed on the support beam; Described running mechanism has two and independently takes turns box bracket and be connected with equalizer by symmetrically arranged vertical shaft on it; This equalizer and change are cross-module hinged by bearing pin and wheels supporting leg; Having active tire and driven tire is installed on two wheel box brackets; Then initiatively tire by chain be fixed on the motor reducer of taking turns on the box bracket and be connected; Between the vertical shaft of driven tire and equalizer, Electrohydraulic push rod is set.Like this, the slippage beam can realize the displacement of both direction and hang bridge floor, the weight of can slinging outside door frame of the electric block on the dolly; In addition, running mechanism is two independently tires, connects by connecting rod, can carry out that arbitrarily angled in 10 ° of scopes turns to and set equalizer realizes the equilibrium of tire having better ground state.
According to above-mentioned application characteristic, the guiding roller is installed at slippage beam and the corresponding end face of support beam.
In concrete application, the support beam upper end is provided with a plurality of saddle crossbeams that distribute by spacing.
Two above-mentioned roller box support sides are provided with track adjusting wheel.
In above-mentioned, have equally conventional operator's compartment, helper, generator set and the electric control system that is had is installed on support beam.
In sum, the used for high-speed railway cross-line bed board gantry crane that the utility model provides, designed slippage beam can realize in support beam that the slippage of both direction is flexible, therefore, in construction, can make the slippage beam hang the bridge floor certain distance according to the particular case of construction, lifting track plate under the bridge; Because the slippage beam slides in supporting traverse, very short from the outstanding needed time of retracted mode that does well, and can regain and escape catenary mast soon.Had conveniently the net bar and crossed the tunnel, operation control is simple.
Description of drawings
