Description
Technical field
The utility model relates to a kind of conveyer portal frame.
Background technology
At present, at water transport market, particularly bulk materials carrier market, the conveyer major part adopted or fixed conveyer, such conveyer causes the long hull that makes when running into stormy waves of hull whole station to wave shakiness in transportation, carrier is easily caused to be turned on one's side, and, take up room when crossing ship lock excessive, reduce the efficiency of ship lock, above-mentioned transport is put on also has part to be provided with portal frame, but its portal frame is for being fixedly mounted on hull, portal frame can not folding and unfolding, occupy great space, to this, application number is 201410142062.6, name is called that the application for a patent for invention of self-discharging sand dredger foldable cage posture belt holder proposes the technical scheme of foldable cage posture belt holder, its technical scheme is by drag link mechanism, hull, cage type one-level arm, four-bar mechanism and cage type secondary arm form, cage type one-level arm and hull are by drag link mechanism connection, cage type one-level arm and cage type secondary arm are by four-bar mechanism connection.Although this scheme solves the problem of belt holder folding and unfolding, but it exists drag link mechanism, and load is excessive, during belt holder work, itself deadweight and material load, up to more than 50 tons, are only born by oil cylinder, once there is the problem that oil cylinder is drawn out, the serious accident that can belt holder be caused to topple, meanwhile, it is too concentrated that belt holder installs the stressed load of basic point, amount of deflection problem that is excessive, that easily cause hull to ftracture, therefore, a kind of conveyer portal frame is developed for being badly in need of.
Utility model content
The purpose of this utility model is to provide a kind of conveyer portal frame, there is portal frame and can rotate recovery along hinge-point 4, removal process is little to hull balance performance impact, occupy little space after recovery, working stability, safety factor are high, after adopting portal frame described in this programme, belt holder install the stressed load of basic point too amount of deflection significantly reduce, be not easy the feature that causes hull to ftracture.
Solution of the present utility model is achieved in that conveyer portal frame, and include two side arms and a crossbeam, two side arms connect into entirety by crossbeam, and the lower end of described side arm is the hinge hole for being connected with pedestal.Like this, because the lower end of side arm and pedestal are hinged, portal frame can be passed on along hinge-point, thus portal frame can be fallen recovery out-of-run time, after conveyer adopts this portal frame, when described conveyer conveying arm is opened, first by hydraulic ram, portal frame and conveying arm are holded up, when conveying arm and pedestal angle are greater than 90 °, hydraulic ram quits work, and opens folding and unfolding winch, conveying arm is put down under Gravitative Loads, when reaching design attitude, winch quits work, and steel rope holds conveying arm.Combined with steel rope by portal frame, the safety factor of gantry frame type conveyer can be increased substantially, conveying arm, steel rope and portal frame define stable triangle mechanical structure, make conveying arm mounting base not fragile, and this mechanical structure can extend the length of conveying arm further, and according to the difference of convey materials, different folding and unfolding steel wire rope of windlass models can be selected can to solve the problem of conveying loads change according to different needs.
Another technical scheme of the present utility model is on above-mentioned basis, and described side arm is truss.Like this, when side arm is truss, the deadweight of portal frame obtains and significantly reduces, and makes gantry frame structure lighter.
Another technical scheme of the present utility model is on above-mentioned basis, and described side arm is triangular truss.Like this, the side arm of portal frame adopts the triangular truss structure that mechanical property is the most stable, and make the mechanical property of portal frame more excellent, in use, portal frame is not yielding.
Another technical scheme of the present utility model is on above-mentioned basis, and two minor face intersection areas of described triangular truss are provided with hinge-point.When two minor face intersection areas of described triangular truss are provided with hinge-point, withdrawal of portal frame can being fallen completely.
Another technical scheme of the present utility model is that, on above-mentioned basis, described hinge-point is connected with amplitude oil cylinder.When hinge-point is connected with amplitude oil cylinder, can control erect and fall to portal frame by oil cylinder, and erecting in working process, oil cylinder can provide support pressure to portal frame, and steel rope combines and firmly to be fixed by portal frame.
Another technical scheme of the present utility model is on above-mentioned basis, and two described side arms are protruding has projection to form conveying arm anchor ear device.Like this, when conveying arm is got back, can take in whole or in part in anchor ear device, conveying arm can be prevented to be shifted in rocking process.
Another technical scheme of the present utility model is, on above-mentioned basis, to be provided with latching device in described anchor ear device.Like this, can further conveying arm be locked.
Another technical scheme of the present utility model is, on above-mentioned basis, described crossbeam to be provided with at least one pulley.Like this, portal frame can be strained by pulley by steel rope, and because have employed pulley, what freely can adjust portal frame erects angle, is conducive to conveyer and works under various complex working condition.
