Abstract
The present invention discloses a moveable track beam of bridge cranes, which is characterized in that a section of moveable beam which can be opened and closed is arranged on a fixed track beam. The opening and the closing of the moveable beam are realized by a moving mechanism arranged on the fixed track beam. The moving mechanism comprises a lever, a rotating shaft, a balancing block, an electric-hydraulic push rod, a coupling head and two supporting seats. The lever is connected with the fixed track beam through the rotating shaft. One end of the lever is fixedly connected with the moveable beam, and the other end is movably connected with the balancing block. One supporting seat is fixed to a strut, and the electric-hydraulic push rod is fixed to the supporting seat. The other supporting seat is fixed to the moveable beam and movably connected with the coupling head. When in work, the electric-hydraulic push rod is started, and the moveable beam is raised through the lever, which realizes the opening of the moveable beam; on the contrary, the moveable beam is closed. The present invention has the advantages of simple structure and convenient use. A position of the track beam of a bridge crane is made into the moveable beam which can be opened and closed. A fracture is formed on the track beam of the bridge crane, which causes a gate of a closed workshop to be closed and causes the closed workshop to maintain the original closing property. The bridge crane is isolated from severe environment which is unsuitable for the bridge crane to stop. The present invention ensures the normal service life of the bridge crane and causes the arrangement of the bridge crane in the closed workshop to become possible.

In many enginerring works, especially the sand blasting operation is arranged at the steel construction piece originating firm.Sand blasting operation meeting produces a large amount of harmful dusts, dust has flown upward gross pollution everywhere air.By the requirement of national environmental protection department, such operation must be carried out in airtight sand blasting workshop, so that the recycling dust, the protection air environment is not contaminated.For dockyard, the workpiece that carries out the sand blasting processing is all quite heavy, the volume that resembles big of this class of body section can reach over one hundred cubic meter, weight can reach tens of tons, even if the small workpiece weight resemble the hatch cover also will reach hundreds of kilograms, they enter and withdraw from station in the sand blasting workshop all need carrying.From job requirements, press in airtight sand blasting workshop, the Special Hoisting Equipment of crane in bridge type as the carrying workpiece is set like that as big part machine manufacture workshop.The dust that the sand blasting operation produces can damage electromechanical appliance, and present crane in bridge type can not be made hermetic again, and crane in bridge type will soon be scrapped in such environment.Therefore so far, almost all do not dispose weight-lifting equipments such as crane in bridge type in the fully enclosed sand blasting workshop.At present still continue to use the transportation by lighter technology that enters and withdraw from station than the time worn workpiece: for size and the bigger workpiece of weight, generally make transportation means with flat truck, but after flat truck is transported into the sand blasting workshop to workpiece with mill floor on the support jack-up workpiece of jacking withdraw from by flat truck, carry out the sand blasting operation after closing the gate in workshop, open the gate, workshop after the sand blasting operation is finished, workpiece is transported with flat truck; To single-piece size and the less workpiece of weight, with small-sized mobile weight-lifting equipment transportation by lighter.Small-sized mobile weight-lifting equipment not only take the workshop payload space and also in the workshop running not nimble, production efficiency is low.
Summary of the invention
The objective of the invention is at the deficiencies in the prior art and a kind of crane in bridge type movable rail of design-calculated beam, it is designed to a part of crane in bridge type track girder can open the portable beam that can close, on the crane in bridge type track girder, form a fracture, the gate in windowfree workshop can be closed, keep its original leakproofness, crane in bridge type obtains isolating with the harsh environment that is not suitable for its delay, ensured the normal service life of crane in bridge type, making becomes possibility at windowfree workshop's configuration crane in bridge type.
The concrete technical scheme that realizes the object of the invention is:
A kind of crane in bridge type movable rail beam, characteristics are: be provided with one section and can open the portable beam that can close on the trapped orbit beam, by being arranged on the folding of the travel mechanism's realization portable beam on the trapped orbit beam.
Described travel mechanism concrete form is: it comprises lever, rotating shaft, balance block, Electrohydraulic push rod, connector, two bearings; Rotating shaft is connected lever on the trapped orbit beam, and lever one end is captiveed joint with portable beam, and an end and balance block flexibly connect, and a bearing is fixed on the pillar, and Electrohydraulic push rod is fixed on the bearing, and another bearing is fixed on portable beam and flexibly connects with connector.
Described travel mechanism concrete form is: it comprises driving lever, follower lever, rotating shaft, Electrohydraulic push rod, connector, bearing; Driving lever is " " shape, by rotating shaft its corner is fixed on the trapped orbit beam, driving lever one end is connected with portable beam, an end is connected with connector, bearing is fixed on the trapped orbit beam, Electrohydraulic push rod is fixed on the bearing and an end is connected with connector, and follower lever one end is fixed on the trapped orbit beam, an end is fixed on the portable beam.
Portable beam is stretched out at track two ends on the described portable beam.
The both sides of described trapped orbit beam are provided with locating plate.
The present invention is simple in structure, easy to use, it is designed to a part of crane in bridge type track girder can open the portable beam that can close, on the crane in bridge type track girder, form a fracture, the gate in windowfree workshop can be closed, keep its original leakproofness, crane in bridge type obtains isolating with the harsh environment that is not suitable for its delay, ensured the normal service life of crane in bridge type, making becomes possibility at windowfree workshop's configuration crane in bridge type.
