Detailed description of the invention
For making the purpose of this utility model, technical scheme and advantage clearly, below in conjunction with accompanying drawing, the utility model embodiment is described in further detail.
As shown in Figure 1 and Figure 2, a kind of flat car transportation prestressed concrete beam of the utility model loading reinforcing device, comprising: frame body, upper frame 1, lower frame 2 and center pin, is characterized in that:
The end face that described frame body comprises the two ends of two crossbeams 3 and two side bearings, 4, two crossbeams 3 is respectively equipped with a crossbeam flange 5; The bottom surface at the two ends of two side bearings 4 is respectively equipped with a side bearing flange 6, two crossbeams 3 and is connected with nut 8 by crossbeam flange 5, side bearing flange 6 and bolt 7 with two side bearings 4; The two ends of lower frame 2 respectively with two crossbeam 3 phase clampings; Upper frame 1 is positioned on lower frame 2, and upper frame 1 is connected by center pin with lower frame 2, upper frame 1 is symmetrically welded with beam gear 9.
Described upper frame 1 is hinged with a secondary diagonal ligament, each diagonal ligament comprises two expansion links and is connected to the connection channel-section steel 10 of expansion link outer end described in two, and described connection channel-section steel 10 is connected with rubber pad 14 and chock 15 by screw bolt and nut.
Described expansion link comprises: connect outer tube 11, pipe 13 in pipe 12 and lower support in upper support, the inside, upper end of described connection outer tube 11 is provided with upper end negative thread, the inside, lower end of described connection outer tube 11 is provided with lower end negative thread, and described upper end negative thread and lower end internal thread rotation are on the contrary; In described upper support, pipe 12 is provided with pipe outside thread in the upper support that matches with the upper end negative thread being connected outer tube; In described lower support, pipe is provided with pipe outside thread in the lower support that matches with the lower end negative thread being connected outer tube.
During loading, prestressed concrete beam 16 is contained on upper frame 1 and at the beam of symmetry and keeps off between 9, by the connection outer tube 11 of rotating extensible arm to adjust the length of diagonal ligament, two pairs of diagonal ligaments are supported from the both sides of prestressed concrete beam 16, increase the fastness and safety of loading.When in transportation, flatcar has the inside and outside discrepancy in elevation by curve or railway line, when one end of upper frame 1 contacts with side bearing 4, the application force that side bearing 4 is subject to upper frame end is then delivered on the flatcar floor in span by two crossbeams 3, now flatcar floor loading surface length equals 2 times of crossbeam spans, i.e. the twice of side bearing length.In this case, the permission load carrying ability on flatcar floor is the twice that side bearing allows load carrying ability when directly contacting with flatcar floor, improves the load carrying ability on flatcar floor.
The foregoing is only preferred embodiment of the present utility model, not in order to limit the utility model, all within spirit of the present utility model and principle, any amendment done, equivalent replacement, improvement etc., all should be included within protection domain of the present utility model.
