Description
Technical field
The present invention relates to a kind of heavy bridge beam slab lifting machine.
Background technology
As large bridge builds increasing, a large amount of to use hundreds of tons of heavy beam slabs, this beam slab raising in the wild
Operational difficulties, are lifted using goliath, and expense is too high, waste substantial amounts of manpower and materials.Make the engineering cost of construction bridge
It is very high, there is no advantage in market competition.
Traditional beam slab lifting method is two goliaths, is sling respectively in one end of beam slab.Such as sling 400 tons
Beam slab, it is necessary at least two 250 tons of cranes hang steel wire rope in one end of beam slab respectively, could normal construction.So require
The place of construction is sufficiently large, gathers two goliaths, and the transition of crane is costly, and lifting is costly.Whole item
Mesh is constructed of high cost.
Therefore, a kind of function admirable and heavy bridge beam slab lifting machine of low cost is urgently studied.
The content of the invention
The present invention devises a kind of heavy bridge beam slab lifting machine in view of the deficiencies of the prior art.
The present invention is in order to achieve the above object, using following scheme：A kind of heavy type bridge beam slab lifting machine, including door frame are total
Into, the translation coaster that is arranged on door frame assembly, the door frame assembly includes crossbeam, and the both ends lower surface of the crossbeam connects respectively
An elevating ram is connected to, the one end of the crossbeam is equipped with translation oil cylinder, and the translation oil cylinder connects with the translation coaster
Connect, the elevating ram and translation oil cylinder are connected with a hydraulic station, and the translation coaster is equipped with boom hoisting.
Further, the translation coaster includes the sliding shoe for being fitted in the beam surface upper, the sliding shoe upper table
The both ends in face are fixed with upper holder block, and the position that the lower section of the crossbeam corresponds to upper holder block is equipped with lower lock block, the upper holder block and
The side of lower lock block is connected by connecting rod, and the lower lock block is equipped with boom hoisting.
Further, the boom hoisting is cable wire.
Compared to the prior art the present invention, has the following advantages that and beneficial effect：Machine operation is lifted using two beam slabs, can
With in narrow and small place, beam slab is hung on a lifting machine per one end with steel wire rope, can safety sling beam slab, haulage vehicle
Pour into below beam slab, beam slab is fallen on transport vehicle.If vehicle is not in beam slab position directly below, lifting machine crossbeam
Coaster transverse moving left and right is translated, to correct position.Work progress is safe and reliable, of low cost.
Brief description of the drawings
Fig. 1 is schematic structural view of the invention；
Fig. 2 is present hydraulic system schematic diagram.
Embodiment
As shown in Figure 1, a kind of heavy type bridge beam slab lifting machine, including door frame assembly, the translation that is arranged on door frame assembly
Coaster, the door frame assembly include crossbeam 1, and the both ends lower surface of the crossbeam 1 is connected to an elevating ram 2, described
The one end of crossbeam 1 is equipped with translation oil cylinder 3, and the translation oil cylinder 3 is connected with the translation coaster, 2 He of elevating ram
Translation oil cylinder 3 is connected with a hydraulic station 4, and the translation coaster is equipped with boom hoisting.The translation coaster includes being fitted in institute
The sliding shoe 5 of beam surface upper is stated, the both ends of 5 upper surface of sliding shoe are fixed with upper holder block 51, the lower section of the crossbeam 1
The position of corresponding upper holder block 51 is equipped with lower lock block 52, and the side of the upper holder block 51 and lower lock block 52 is connected by connecting rod 53, under
Briquetting 52 and the common limit slippage block 5 of upper holder block 51 slide to deviate from crossbeam 1, wherein, lower lock block 52 does not connect with crossbeam 1
Touch, play certain counterweight effect.Furthermore it is possible to set pulley blocks in the lower surface of sliding shoe 5, set in the upper surface of crossbeam 1
Put corresponding slide.The lower lock block 52 is equipped with boom hoisting, and boom hoisting can be steel wire cable 6, for bundled fixed
Need the beam slab 7 lifted by crane.
As shown in Fig. 2, motor drives hydraulic oil pump work, a liter switch is pressed, high pressure oil passes through solenoid directional control valve 1
Into flow divider 83, oil mass is assigned to the rodless cavity of two elevating rams 2 by flow divider 83, and elevating ram 2 lifts 1 He of crossbeam
7 synchronous balance of beam slab rises；Similarly, by down switch, crossbeam 1 and the synchronous decline of beam slab 7 are realized.If beam slab 7 is not in vehicle
Surface, left or right switch can be pressed, high pressure oil gives translation oil cylinder 3 fuel feeding by solenoid directional control valve 2 82, realizes translation
Beam slab 7 moves left and right coaster on crossbeam 1 in tow.
In the use of the present invention, as needed, using coordinating before and after 2 or more than 2 lifting machines, beam slab 7 is fixed respectively
Both ends, synchronous lifting, operation stability higher.
The above is only the preferred embodiment of the present invention, it is noted that for the ordinary skill people of the art
For member, without departing from the technical principles of the invention, some improvement and modification, these improvements and modifications can also be made
Also it should be regarded as protection scope of the present invention.
