Full-manual maintenance-free simple hoisting system
Technical Field
The invention relates to the technical field of hoisting, in particular to a full-manual maintenance-free simple hoisting system.
Background
When equipment in large-scale factory building, workshop, transformer substation installs and overhauls, because equipment is from great, equipment wastes time and energy when indoor transportation operation, very inconvenient. Some large-scale factory buildings, workshops and substations are provided with travelling cranes. The crane belongs to special equipment, the primary installation cost is high, the later maintenance cost is high, the maintenance period of indoor equipment is generally longer, the use rate of hoisting equipment is low, the crane installation economy is very poor, and meanwhile, potential safety hazards exist in the use of electrical equipment.
The manual monorail crane does not belong to the category of special equipment, and the expensive cost required by the maintenance of hoisting equipment can be saved by using the manual monorail crane. However, the monorail trolley only runs on the fixed rail, and the lifted equipment is required to be right below the rail, so that the lifting range is smaller, and the use limitation is stronger.

The rail car is a manual trolley.
The connecting hoist and the lifting hoist are both manual hoist.
The transverse loading beam is an H-shaped steel beam formed by an upper flange, a lower flange and stiffening ribs arranged between the upper flange and the lower flange, the stiffening ribs are uniformly distributed along the length direction of the transverse loading beam, and two ends of each stiffening rib are fixedly connected with the upper flange and the lower flange respectively.

And the lower lifting lug of the loading beam is positioned at the middle part of the lower side of the transverse loading beam.
The beneficial effects of the invention are as follows:
the invention can realize lifting of the weight right below the track or between the tracks; when a heavy object positioned between the rails is lifted, the heavy object is lifted by means of the transverse loading beam, two ends of the transverse loading beam are hung below the longitudinal rails through connecting hoists and are lifted to a specified height, and then a hoisting hoist is hung on the transverse loading beam, and the hoisting hoist is positioned right above the lifted heavy object and is used for lifting the heavy object, and rail cars connected with two ends of the transverse loading beam simultaneously run when the heavy object is transported.
When the weight right below the track is lifted, the transverse loading beam is disassembled, the weight is directly lifted by the connecting hoist, and the weight is transported by the track car.
The invention can solve the problem of heavy object lifting between monorail lifting tracks, improve the use efficiency of the tracks and reduce the paving amount of the tracks. The hoisting equipment has low installation and maintenance cost, convenient use and higher popularization value.

The stiffening ribs 7 are uniformly distributed along the length direction of the transverse loading beam, two ends of each stiffening rib 7 are fixedly connected with the upper flange and the lower flange respectively, and because the stress state is complex, the spacing of the stiffening ribs is small, and the spacing is about 0.8-1.2 h (h is transverse loading Liang Lianggao), and the structural strength of the transverse loading beam 6 is improved through the structural design.
The invention can realize lifting of the weight right below the track or between the tracks; when a heavy object positioned between the rails is lifted, the heavy object is lifted by means of the transverse loading beam 6, two ends of the transverse loading beam 6 are hung below the longitudinal rails 1 through the connecting hoist 3 and are lifted to a specified height, then the lifting hoist 4 is hung on the transverse loading beam 6, and the lifting hoist 4 is positioned right above the lifted heavy object and is used for lifting the heavy object, and the rail cars 2 connected with the two ends of the transverse loading beam 6 are operated simultaneously when the heavy object is transported.
When the heavy object positioned under the track is lifted, the transverse loading beam 6 is detached (the transverse loading beam 6 and the hoisting hoist 4 hung under the transverse loading beam 6 can be detached and independently stored, the occupied structural space is small), the heavy object is directly lifted by the connecting hoist 3, and the heavy object is transported by the track car 2.
