Abstract
The utility model relates to a flexibility precompensating adjustable level beam applied in towers in the technical field of chemical industry and petrochemical industry, which is mainly composed of a steel beam and a compensating beam. Before the utility model is used for loading bearing, each adjusting screw on the compensating beam is adjusted respectively, and compensating beam humps and bends upward to precompensate a flexibility. After the compensating beam is used for loading bearing uniform loads, a flexibility deformation generated by the precompensation of the flexibility and a flexibility deformation generated by bearing the uniform loads counteract each other; the compensating beam becomes a level beam; the levelness and the precision of each liquid distributing hole on the gas and liquid distributor are enhanced. The utility model has the advantages of simple structure, convenient operation, and reliable performance.
Description
The utility model relates to the tower inner member of a kind of chemical industry, petrochemical industry.
The girder steel of making of section bars such as i iron in the existing tower is used to carry tower inner members such as gas-liquid distributor.Because weight, the weight of gas-liquid distributor institute load bearing fluid and the deadweight of girder steel of gas-liquid distributor, make girder steel certainly lead to downward deflection deformation, have a strong impact on the levelness of each liquid distributing hole on the gas-liquid distributor that is carried, and then have influence on the operational effect of tower.
The purpose of this utility model is to provide a kind of adjustable horizontal beam of precompensation amount of deflection of simple in structure, easy to operate, dependable performance.
In order to achieve the above object, the utility model is realized by the following technical solutions: the utility model mainly is made up of girder steel and compensation beam, is made with steel.Plane on girder steel is processed with two or more positioning screw holes.Place the compensation beam on the girder steel.The compensation beam is a horizontal steel plate of bar shaped, which is provided with and is directed upwardly the supporting surface that is used to support gas-liquid distributor.Supporting surface can be horizontal plane, tapered plane, also can be curved surface.Supporting surface on the same compensation beam can be same complete supporting surface, also can be two or more a plurality of supporting surfaces.The two ends of compensation beam are processed with two or more locating holes, pass the positioning screw hole place that locating hole is fixed on the compensation beam on girder steel with dog screw.The compensation beam is provided with 1～30 and regulates screw, and each is regulated the screw place adjustment screw is installed.
According to the size of institute's application tower diameter, the compensation beam quantity that disposes on the same girder steel can be 1～20.
The utlity model has advantage simple in structure, easy to operate, dependable performance.
Below in conjunction with accompanying drawing content of the present utility model is further elaborated.
Fig. 1 is a front view of the present utility model;
Fig. 2 is a vertical view of the present utility model;
Fig. 3 is the stress deformation schematic diagram of the utility model after carrying is used.
In above-mentioned figure, [1] is girder steel; [2] be the compensation beam; [3] be dog screw; [4] be adjustment screw.
The utility model mainly is made up of girder steel [1] and compensation beam [2], is made with steel.Plane on girder steel is processed with two or more positioning screw holes.Place the compensation beam on the girder steel.The compensation beam is a horizontal steel plate of bar shaped, which is provided with and is directed upwardly the supporting surface that is used to support gas-liquid distributor.Supporting surface can be horizontal plane, tapered plane, also can be curved surface.Supporting surface on the same compensation beam can be same complete supporting surface, also can be two or more a plurality of supporting surfaces.The two ends of compensation beam are processed with two or more locating holes, pass the positioning screw hole place that locating hole is fixed on the compensation beam on girder steel with dog screw [3].The compensation beam is provided with 1～30 and regulates screw, and each is regulated the screw place adjustment screw [4] is installed.
According to the size of girder steel total length, the compensation beam quantity that is disposed on the same girder steel can be 1～20.
The utility model can calculate earlier the deflection data of each adjustment screw place girder steel after the distortion of carrying uniformly distributed load respectively according to the mechanics deflection curve equation before carrying is used:
Wherein, l is the girder steel total length; X is the horizontal coordinate data of girder steel adjusted screw place apart from the girder steel end; Q is the uniformly distributed load of girder steel desire carrying; E is the elastic modulus of tensile compression of girder steel material; I is the moment of inertia of girder steel.
Adjust each adjustment screw on the compensation beam respectively, make the bending that raises up of compensation beam, and making the compensation beam conform to the deflection data of the girder steel that is calculated after the distortion of carrying uniformly distributed load in the high deformation data at each adjustment screw place, direction is opposite, plays the effect of precompensation amount of deflection.After the compensation beam was carrying the uniformly distributed load use, its precompensation amount of deflection was cancelled each other with the carrying deflection deformation that uniformly distributed load produced, and the compensation beam becomes horizontal beam, and the levelness precision that compensates each liquid distributing hole on the gas-liquid distributor that beam carried will improve greatly.
Fig. 1 demonstrates the compensation beam was finished the bending that raises up after the precompensation amount of deflection is debugged with adjustment screw before carrying is used schematic diagram;
Fig. 3 demonstrates compensation beam precompensation amount of deflection after carrying is used becomes horizontal beam after cancelling each other with the carrying deflection deformation that uniformly distributed load produced.
The utlity model has advantage simple in structure, easy to operate, dependable performance.
