A end carriage walking mechanism is fixedly connected, and the both ends of fixed link and two end carriage walking mechanisms pass through the connecting rod being obliquely installed and consolidate
Fixed connection, is fixedly connected with the vertical web rod being vertically arranged, fixed link and bottom between the both ends of fixed link and corresponding bottom plate both ends
Multiple spaced diagonal web members of inclination are fixedly connected between plate, and two neighboring diagonal web member is symmetrical arranged, connecting rod and bottom
The support rod being obliquely installed is fixedly connected between plate.
The connecting rod and support rod are perpendicular, and minor node stiffening plate is fixedly connected between connecting rod and support rod.
Big joint strengthening plate is fixedly connected between the upper end of the vertical web rod and the upper end of diagonal web member adjacent thereto,
Also big joint strengthening plate is fixedly connected between the upper end of adjacent diagonal web member.
The backplate being vertically arranged is fixedly connected on bottom plate between two end carriage walking mechanisms.
The section approximation of the girder is in " inverted trapezoidal ".
The fixed link, connecting rod, vertical web rod, diagonal web member, support rod are square bar.
Beneficial effects of the present invention:
(1) structure of the invention is made of fashioned iron, and self weight is much lighter than conventional hoist, and operation does not need especially big
Power, operating cost is low, and small to the wheel load of track, the requirement to workshop is less, and use scope is wider；
(2) electric block of the invention is changed under the bottom plate of girder and is run, and the bottom plate of the girder has directly been routed to end,
Compared with former girder, the critical distance of suspension hook to metope can be transferred to minimum, increase the effective working space of existing workshop；
(3) the structure safety and reliable performance of the invention, the low use of failure rate sinking and later maintenance cost.

Specific embodiment
To keep the purpose of the present invention, technical scheme and beneficial effects clearer, the present invention is implemented with reference to the accompanying drawing
Mode is described in further detail.
As shown in FIG. 1 to FIG. 2, the present invention provides a kind of electric single-beam bridge crane main beam structure, which is cut
Face approximation is in " inverted trapezoidal ", can be improved safety and stability of the entire girder in promotion and mobile operational process in this way,
It further include the bottom plate 2 and top plate 3 of horizontal parallel setting, the both ends of top plate 3 are fixed including symmetrically arranged end carriage walking mechanism 1
It is connected with symmetrically arranged fixed link 4, the both ends of bottom plate 2 are fixedly connected with two end carriage walking mechanisms 1 respectively, fixed link 4
Both ends and two end carriage walking mechanisms 1 are fixedly connected by the connecting rod 5 being obliquely installed, the both ends of fixed link 4 with it is corresponding
It is fixedly connected with the vertical web rod 6 being vertically arranged between 2 both ends of bottom plate, multiple inclinations are fixedly connected between fixed link 4 and bottom plate 2
Spaced diagonal web member 7, and two neighboring diagonal web member 7 is symmetrical arranged, the upper end of the vertical web rod 6 and oblique abdomen adjacent thereto
It is fixedly connected with big joint strengthening plate 10 between the upper end of bar 7, is also fixedly connected with big section between the upper end of adjacent diagonal web member 7
Point stiffening plate 10.The support rod 8 being obliquely installed, connecting rod 5 and 8 phase of support rod are fixedly connected between connecting rod 5 and bottom plate 2
Vertically, and between connecting rod 5 and support rod 8 it is fixedly connected with minor node stiffening plate 9, makes its support construction more safety jail
It leans on, the fixed link 4, connecting rod 5, vertical web rod 6, diagonal web member 7, support rod 8 are square bar, are both grasped in this way convenient for the welding of girder
