Abstract

The utility model relates to the field of engineering equipment, in particular to a level adjusting device for a hoisted steel box girder. The level adjusting device for the hoisted steel box girder comprises a sand bucket, a piston, a sand discharge pipe, a flange and a lifting lug, wherein the sand bucket is of a barrel-shaped structure with the upper end of being opened and the lower end of being closed, and the sand bucket is filled with sand; the piston consists of a piston pipe and a bearing plate connected with the upper end surface of the piston pipe, and the lower end surface of the piston pipe is connected with a piston bottom plate pressing the top of the sand; and the side wall of the sand bucket is connected with the sand discharge pipe communicated with an inner cavity of the sand bucket, the other end of the sand discharge pipe is connected with the flange, and the lifting lug is welded on the side wall of the sand bucket. In the utility model, the steel box girder is arranged on the bearing plate of the piston, and the level of the top of sand in the sand bucket is a little higher than the designed level of the steel box girder; and after the steel box girder is hoisted in place, if the level is higher than the designed level, the blind flange is opened to discharge a little of sand from the bucket, and then the flange is closed so that the purpose of adjusting the level of the steel box girder can be achieved, thereby being convenient in use, and having simple and practical structure as well as low manufacturing cost.

Description

Steel case beam lifting absolute altitude adjusting device

Technical field

The utility model relates to a kind of engineering equipment field, relates in particular to the lifting absolute altitude adjusting device of steel case beam on the infrastructure such as a kind of viaduct.

Background technology

Along with the increase of automobile quantity, the pressure of urban traffic also increases day by day.Infrastructure such as construction viaduct can be alleviated the urban traffic obstruction significantly.For reduce the influence to the city normal traffic as far as possible, viaduct at the parting of the ways adopts the steel box-beam structure usually in the construction process, because steel case beam span is big, the engineering time short, be convenient to produce in factory, thereby is used widely.Because steel case beam volume and weight is all bigger, generally needs special hoisting machine tool to lift steel case beam, but use existing hoisting machine tool steel case beam absolute altitude to be regulated and inconvenience.

Summary of the invention

At the problems referred to above, the purpose of this utility model is to provide a kind of steel case beam simple in structure, easy to use, that cost is low to lift the absolute altitude adjusting device.

The utility model solves the problems of the technologies described above the technical scheme that is adopted: a kind of steel case beam lifting absolute altitude adjusting device, its difference is: it includes Sand Bucket, piston, puts sand tube, flange and hanger, Sand Bucket is the tubular structure of upper end open, lower end closed, is contained with sand in the Sand Bucket; Piston is made up of base plate, piston tube, piston base plate, and base plate is connected in the piston tube upper surface, and the piston tube lower surface connects the piston base plate, and the piston base plate is pressed in the sand top; The Sand Bucket sidewall is connected with puts sand tube, puts sand tube and is communicated with the Sand Bucket inner chamber, puts the sand tube other end and is connected with flange, and the Sand Bucket sidewall is welded with hanger.

Described put the sand tube axis downward-sloping with horizontal direction be 15 ° of angles.

The number of described hanger is three, is welded on evenly distributedly on the Sand Bucket sidewall.

The utility model places steel case beam on the base plate of piston, the design elevation of a little higher than steel case of the absolute altitude beam at sand top in the Sand Bucket, behind the steel case beam hoisted in position, if absolute altitude is higher than design elevation, open blind flange the sand in the bucket is emitted a little, close flange again, reach the purpose of regulating steel case beam absolute altitude, easy to use, apparatus structure is simple and practical, low cost of manufacture.

Fig. 1 is the sectional view of the utility model embodiment;

Description of symbols among the figure: the 1-base plate, the 2-hanger, 3-is put sand tube, 4-flange, 5-base plate, 6-Sand Bucket, 7-sand, 8-piston base plate, 9-piston tube.

The specific embodiment

In order to understand the utility model better, below in conjunction with embodiment and accompanying drawing the technical solution of the utility model is described further, referring to Fig. 1:

Press a kind of steel case beam lifting absolute altitude adjusting device that the utility model is implemented, it includes Sand Bucket 6, piston, puts sand tube 3, flange 4 and hanger 2, and Sand Bucket 6 is the tubular structure of upper end open, lower end closed, be contained with sand in the Sand Bucket 6, the design elevation of a little higher than steel case of the absolute altitude at sand top beam.Described piston is used to support steel case beam, be made up of piston tube 9, base plate 1, piston base plate 8, base plate 1 is connected in piston tube 9 upper surfaces, and the lower end of piston tube 9 connects 8 sealings of piston base plate, the sand that is stressed when preventing work can enter in the piston tube 9, and piston base plate 8 is pressed in the sand top.Sand Bucket 6 sidewalls are connected with and put sand tube 3 near base plate 5, put sand tube 3 and are communicated with Sand Bucket 6 inner chambers, put sand tube 3 other ends and are connected with and are used to control the flange 4 of putting sand, and flange 4 inner caps offer through hole, and enclosing cover seals.In order to put sand better, it is downward-sloping in a certain angle with horizontal direction to put sand tube 3 axis, so just can utilize the deadweight of sand to flow out Sand Bucket 6.If angle is too little, and it is bad that deadweight component flows out effect less than frictional force, and if angle is too big, and the rate of outflow of sand is too fast, and bad the closing of flange 4 enclosing covers in the present embodiment, puts that sand tube 3 axis are downward-sloping to be 15 ° of angles with horizontal direction.For the ease of handling, Sand Bucket 6 sidewalls are welded with hanger, and the number of hanger is three, are welded on evenly distributedly on Sand Bucket 6 sidewalls, and handling is more stable like this, guarantee construction safety.

Sand Bucket 6 is welded by the steel pipe of φ 325 * 8mm and the base plate 5 of δ=20mm in the present embodiment, put sand tube 3 and be the steel pipe of φ 89 * 4mm, piston is by the steel plate assembly welding of diameter phi 299 * 8mm steel pipe and δ=20mm, and hanger is welded on Sand Bucket 6 sidewalls by the steel plate cutting of δ=10mm.Steel case beam is before lifting operation, earlier with filling sand in the Sand Bucket 6, make the design elevation of a little higher than steel case of the absolute altitude beam at Sand Bucket 6 sand tops, be positioned on the base plate 1 of piston behind the steel case beam hoisted in position, steel case back standard laid down by the ministries or commissions of the Central Government height is carried out repetition measurement, if absolute altitude is higher than design elevation, flange 4 enclosing covers are opened, the sand in the bucket is emitted a little, make piston drop to design elevation, closure fange 4 then, thereby reach the purpose that envelope is regulated steel case beam absolute altitude.The utlity model has simple in structure, make and the low characteristics of cost easily, and low cost of manufacture helps applying.

Above disclosed only is preferred embodiment of the present utility model, can not limit the interest field of the utility model certainly with this, and therefore the equivalence of being done according to the utility model claim changes, and still belongs to protection domain of the present utility model.
