Detailed description of the invention
Technical scheme in the application is understood better in order to make those skilled in the art person, below in conjunction with the accompanying drawing in the embodiment of the present application, technical scheme in the embodiment of the present application is clearly and completely described, obviously, described embodiment is only some embodiments of the present application, instead of whole embodiments.
Based on the embodiment in the application, those of ordinary skill in the art are not making the every other embodiment obtained under creative work prerequisite, all should belong to the scope of the application's protection.
See accompanying drawing, accompanying drawings provide a kind of specific embodiment of portal frame, as shown in drawings, this portal frame comprises the suspention beam 3 of the pedestal 1 of front end, the tie-beam 2 at middle part and tail end, wherein, pedestal 1 is mainly used in other mechanism be arranged on above it to be fixedly mounted on together on ship deck, and tie-beam 2 has been mainly used in connection function, and suspention beam 3 is for lifting cargo.
Be provided with the first bracing frame 4 between pedestal 1 and tie-beam 2 and described first bracing frame 4 is triangular shape, pedestal 1 and tie-beam 2 are hinged on two base angle places of the first bracing frame 4 respectively, and pedestal 1 and the first bracing frame 4 side loins are provided with the first expansion link 5.
By setting up the first bracing frame 4 of triangular shape, both can keep the stable of the first bracing frame 4 itself, and pedestal 1 and the installation of tie-beam 2 can have been facilitated again, the erection of the control of the first expansion link 5 and following first stay cord 8 and the second stay cord 9 can also be facilitated simultaneously.
In the present embodiment, pedestal 1 and tie-beam 2 are hinged on two base angles of the first bracing frame 4 respectively.First expansion link 5 is arranged between pedestal 1 and the first bracing frame 4 side waist, by the fore and aft motion of the first expansion link 5, first expansion link 5 can pull the first bracing frame 4 cw or rotate counterclockwise, so drive tie-beam 2 together with the hinge-point between pedestal 1 and the first bracing frame 4 for fulcrum.
In the present embodiment, the second bracing frame 6 is provided with and described second bracing frame 6 is triangular shape between tie-beam 2 and suspention beam 3, second bracing frame 6 three drift angle place is provided with through hole 601, wherein, second bracing frame 6 has in two through holes 601 and is provided with articulated mounting and is hinged on tie-beam 2 respectively with on suspention beam 3, is provided with the second expansion link 7 between the through hole 601 that the second bracing frame 6 is remaining and tie-beam 2.
So, by the fore and aft motion of the second expansion link 7, second expansion link 7 can pull the second bracing frame 6 cw or rotate counterclockwise, the second bracing frame 6 and then drive suspention beam 3 with the hinge-point of the second bracing frame 6 and tie-beam 2 for fulcrum, thus realizes rising or the decline of suspention beam 3.
In the present embodiment, triangular shape second bracing frame 6 offering 3 through holes 601 both can meet connection and the strength demand of the second bracing frame 6, can also reduce the weight of the second bracing frame 6 simultaneously.
In the present embodiment, between pedestal 1 and tie-beam 2, be provided with the first stay cord 8, be provided with between pedestal 1 and suspention beam 3 second stay cord 9, first stay cord 8 and the second stay cord 9 all frame at the first bracing frame 4 drift angle place.So, first stay cord 8 and the second stay cord 9 can with the first bracing frame 4 drift angle place for the strong points, coordinate the first expansion link 5 control linkage beam 2 and rising or decline of suspending beam 3 in midair together with the second expansion link 7, thus the folding or stretching, extension of control linkage beam 2 and suspention beam 3.Accompanying drawing 2 is the structural representation of tie-beam 2 when folding, and accompanying drawing 3 is tie-beam 2 and suspention beam 3 structural representation when all folding.
Consider that installing and using of steel rope is all more convenient, and steel rope can bear larger pulling force, in the present embodiment, the first stay cord 8 and the second stay cord 9 are steel rope.
Consider that telescoping hydraulic cylinder axial length is shorter, do not need to take too large space and compact conformation, larger stroke and pressure can be provided simultaneously, greatly can meet the Hydraulic for lifting load demand in the machinery such as hoisting crane, motor-tilter, in the present embodiment, the first expansion link 5 and the second expansion link 7 are telescoping hydraulic cylinder.
In the present embodiment, be intensifier whole machine balancing, the first bracing frame 4 and the second bracing frame 6 are two and are separately positioned on tie-beam 2 and suspention beam 3 both sides.So, balance when can ensure that this device lifts by crane further.
In the present embodiment, for making the rotation of the easier control linkage beam 2 of the first expansion link 5, between the first bracing frame 4 and tie-beam 2, be provided with connecting panel 10.So, when the first expansion link 5 pulls the first bracing frame 4 to rotate, tie-beam 2 there are two the places simultaneously stressed hinge-point of tie-beam 2 (point of connection of connecting panel 10 and tie-beam 2, first bracing frame 4 with), like this, tie-beam 2 rotates more convenient, more laborsaving, the rotation of the easier control linkage beam 2 of the first expansion link 5.
In the present embodiment, more easily controlling the rotation of suspending beam 3 in midair for making the second expansion link 7, between the second bracing frame 6 and suspention beam 3, being also provided with connecting panel 10.
In the present embodiment, more laborsaving when driving tie-beam 2 for making the first expansion link 5, first expansion link 5, pedestal 1, three joinings that tie-beam 2 and the first bracing frame 4 form are triangularly arranged, wherein, the joining of the first expansion link 5 and the first bracing frame 4 is greater than the joining of pedestal 1 and the first bracing frame 4 to the distance between tie-beam 2 and the joining of the first bracing frame 4 to the distance between pedestal 1 and the joining of the first bracing frame 4, joining to the distance between tie-beam 2 and the joining of the first bracing frame 4 of pedestal 1 and the first bracing frame 4 is greater than the distance between joining to the first expansion link 5 of tie-beam 2 and the first bracing frame 4 and the joining of the first bracing frame 4.
So, time first expansion link 5 starts, at three the joining places that are triangularly arranged, the arm of force is driven to have selected the longest form, namely the joining of the first expansion link 5 and the first bracing frame 4 is the longest to the distance between pedestal 1 and the joining of the first bracing frame 4, so, first expansion link 5 can provide maximum drive torque, especially when the straight line that joining to the joining of pedestal 1 and the first bracing frame 4 of the first expansion link 5 and the first bracing frame 4 forms and the first expansion link 5 perpendicular, so can more convenient driving tie-beam 2.
In the present embodiment, for strengthening tie-beam 2 and the intensity of suspention beam 3, tie-beam 2 and suspention beam 3 are provided with reinforced rib 11.So, can ensure the lifting safety of this portal frame further, meanwhile, this portal frame can lift by crane larger weight.
Generally, this portal frame can maintain the normal lifting of goods, and the integral structure with timer is compact, does not need too large installing space, and device overall weight is smaller, and can also bear very large hoisting weight.
Above a kind of portal frame provided by the utility model is described in detail.Apply specific case herein to set forth principle of the present utility model and embodiment, the explanation of above embodiment just understands method of the present utility model and core concept thereof for helping.Should be understood that; for those skilled in the art; under the prerequisite not departing from the utility model principle, can also carry out some improvement and modification to the utility model, these improve and modify and also fall in the protection domain of the utility model claim.
