Abstract
Disclosed is a hydraulic locking mechanism for movable supporting legs of a bridge erecting machine. The movable supporting legs comprise a pair of telescopic columns, each telescopic column consistsof a plurality of telescopic column units, each telescopic column unit is in sleeve connection sequentially, and the hydraulic locking mechanism is used for locking each telescopic column unit. The locking mechanism includes plugholes and inserted pin shafts, wherein the plugholes are transversely arranged on the telescopic column units, the inserted pin shafts match with the plugholes, each plughole is placed at the connecting position of two adjacent telescopic column units, each inserted pin shaft is equipped with a hydraulic cylinder, one end portion of each inserted pin shaft is connectedwith a piston rod of the hydraulic cylinder, and each inserted pin shaft driven by the hydraulic cylinder is inserted into each plughole or released from the plughole. The hydraulic locking mechanismhas the following advantages that when the movable supporting legs of the bridge erecting machine support main beams, the inserted pin shafts are inserted into the plugholes to increase the load-carrying capacity of each telescopic column unit so as to enable the movable supporting legs of the bridge erecting machine to support the main beams stably, safety performance of erecting bridges is enhanced, application is convenient, and the convenience of construction is improved because the inserted pin shafts are employed to fasten the telescopic column units.
Description
Technical field
The utility model relates to a kind of bridge formation machine, particularly a kind of hydraulic locking mechanism.
Background technology
1318 kilometers of Beijing-Shanghai High-Speed Railway length overalls, the bridge ratio is nearly 80% in the railway, and construction has that the beam type is many, lift heavy big, set up the precision height, need to adapt to that change is striden and curve such as sets up at characteristics.Movable supporting legs comprises the telescopic mast that is positioned at the crossbeam both ends, telescopic mast is made up of the multi-joint telescoping pole unit, each telescopic mast unit socket successively, each telescopic mast unit disposes its flexible hydraulic mechanism of control respectively, hydraulic mechanism comprises a plurality of oil cylinders, the piston rod of each oil cylinder is connected with the telescopic mast unit respectively, and each cylinder action drives the telescopic mast unit action that is attached thereto, and telescopic mast is stretched out or withdraws.The weight of case beam can reach 900 tons, when the weight lifting mechanism lifting case beam of bridge formation machine is set a roof beam in place, movable supporting legs as bridge formation machine rear fulcrum has born very big power, and only relies on the oil cylinder in the telescopic mast can not bear so big power, so need provide a kind of locking mechanism for telescopic mast.
Summary of the invention
In order to overcome the deficiencies in the prior art, the purpose of this utility model is to provide a kind of locking mechanism that can lock each telescopic mast unit for the movable supporting legs of bridge erecting machine telescopic mast.
In order to reach above purpose, the technical scheme that the utility model is taked is: a kind of hydraulic locking mechanism, this hydraulic locking mechanism is used to the movable supporting legs of the machine of building bridge, the movable supporting legs of bridge formation machine comprises a pair of telescopic mast, described each telescopic mast is made up of the multi-joint telescoping pole unit, described each telescopic mast unit socket successively, described hydraulic locking mechanism is used for each telescopic mast unit is locked, described locking mechanism comprises the jack that laterally is opened on the described telescopic mast unit, the bolt axle that matches with described jack, described jack all is positioned at adjacent two positions that the telescopic mast unit joins mutually, described bolt axle is equipped with hydraulic cylinder, one end of described bolt axle is connected with the piston rod of described hydraulic cylinder, and described bolt axle inserts described jack or withdraws from from jack under the driving of described hydraulic cylinder.
Preferably, all offer four jacks on the described two adjacent telescopic mast unit, these jacks run through the front and rear wall of described telescopic mast unit.
Because the enforcement of above technical scheme, the utility model compared with prior art, has following advantage: when movable supporting legs of bridge erecting machine supports girder, inserting bolt axle has increased the weight capacity of each telescopic mast unit, make movable supporting legs of bridge erecting machine can support girder stably, increased the security performance when building bridge, it is fastening easy to use to adopt bolt axle to carry out, and increases the convenience of construction.
Description of drawings
Accompanying drawing 1 is front view of the present utility model (telescopic mast is in the state of stretching out, and hydraulic cylinder is not shown);
Accompanying drawing 2 is front view of the present utility model (telescopic mast is in retracted mode, and hydraulic cylinder is not shown);
Accompanying drawing 3 is a left view of the present utility model;
Wherein: 1, telescopic mast; 2, jack; 3, bolt axle; 4, hydraulic cylinder.
The specific embodiment
Below in conjunction with the accompanying drawing and the specific embodiment the utility model is described in further detail:
As accompanying drawing 1 to shown in the accompanying drawing 3, a kind of hydraulic locking mechanism, movable supporting legs comprises a pair of telescopic mast 1 that is hinged on the crossbeam both ends, this vertically is provided with when the bridge formation frame bridge telescopic mast 1, each telescopic mast 1 is made up of two joint telescopic mast unit.In each telescopic mast 1, the bottom of the telescopic mast unit above being positioned at socket-connects with the upper end of the telescopic mast unit that is positioned at the below.As shown in Figure 2, when telescopic mast need not load-bearing, the telescopic mast unit of the withdrawal below, telescopic mast unit above being positioned at was to reduce the height of whole telescopic mast.As shown in Figure 1, when telescopic mast needed load-bearing, the telescopic mast unit that is positioned at the top stretched out from the telescopic mast unit that is positioned at the below, thereby makes telescopic mast support girder.Because the telescopic mast unit in the telescopic mast 3 is socket, its weight capacity is poor, and need to fix between the telescopic mast unit, so be telescopic mast 3 configuration locking mechanisms, this locking mechanism comprises four jacks 2 that laterally are opened on the telescopic mast unit, the bolt axle 3 that matches with each jack 2, jack 2 all is positioned at adjacent two positions that the telescopic mast unit joins mutually, and jack 2 passes the front and rear wall of telescopic mast successively.
In order to make bolt axle 3 can insert hydraulic cylinder 4 automatically and from hydraulic cylinder 4, to return, as shown in Figure 3, be bolt axle 3 configuration hydraulic cylinders 4, one end of bolt axle 3 is connected with the piston rod of hydraulic cylinder 4, when telescopic mast 1 needs load-bearing, the telescopic mast unit that is positioned at the top stretches out, when four jacks, 2 alignment on the two telescopic mast unit up and down, bolt axle 3 inserts jack 2 under the driving of hydraulic cylinder 4, set a roof beam in place finish after, bolt axle 3 is return under the effect of hydraulic cylinder 4, is positioned at the telescopic mast unit withdrawal of top then.
As load-supporting part, bolt axle 3 need have enough intensity, so bolt axle 3 is selected suitable model and material that can load-bearing for use, as stainless steel alloy etc.
By present embodiment as can be seen, adopt the utility model can effectively increase the weight capacity of telescopic mast 1, increased the security performance of bridge formation machine and the convenience of constructing.
