Cantilevered moving and rotating belt conveying and distributing machine and work assigning method

Abstract

The invention discloses a cantilevered moving and rotating belt conveying and distributing machine and a work assigning method. The cantilevered moving and rotating belt conveying and distributing machine comprises a travelling mechanism, a revolving mechanism, a motor and reducer combination, a revolving platform, a distributing mechanism, a first belt conveyor, a feed mechanism, a second belt conveyor, a guide chute and a cab. The travelling mechanism comprises a movable platform with a wheel and a gear motor arranged thereunder; the revolving mechanism comprises a rotating shaft which is perpendicularly arranged on the movable platform; the motor and reducer combination is arranged under the movable platform, and an output shaft of the reducer is connected with the rotating shaft through a coupler; the revolving platform with the middle portion connected to the upper end of the rotating shaft is driven by the rotating shaft to be revolved; the distributing mechanism comprises a cantilever, and one end of the cantilever is fixed on the revolving platform; the first belt conveyor is arranged along the cantilever; the feed mechanism comprises a steel-structured support frame which is arranged obliquely upwards and fixed on the movable platform; the second belt conveyor is arranged along the longitudinal direction of the steel-structured support frame; the guide chute is located above the revolving platform, and materials on the second belt conveyor are conveyed to a material receiving port of the first belt conveyor via the guide chute; the cab is arranged on the revolving platform. The revolving angle of the cantilever of the distributing machine can reach by 270 degrees, so that distributing on an entire site of a storage yard can be realized.

Description

technical field [0001] The invention relates to a yard machine, in particular to a cantilever-type moving rotary belt-type conveying and distributing machine and an arrangement operation method. Background technique [0002] At present, the traditional machinery and equipment in domestic storage yards mainly include: rake hoppers, belt conveyors, grab cranes, stackers and reclaimers, loading and unloading machines, excavators, etc. The above-mentioned mechanical equipment can be configured into various storage yard production forms according to different process requirements. [0003] The sand and gravel used in the preliminary construction of Baosteel’s Zhanjiang project was originally planned according to the traditional method. The 5,000-ton self-unloading ship at sea unloaded the material to the transition silo at the dock, picked it up through several large-scale mobile belt conveyors, and then sent the material to the designated Location; Finally, several ZL50 loading...

AI Technical Summary

Problems solved by technology

[0005] (1) Unable to achieve continuous production, forcing the operation rate of offshore self-unloading ships to be significantly reduced, thereby significantly increasing production costs;

[0006] (2) During the production process, the materials have been transferred many times, and the number of landing points has increased, and the dust is very serious, and it is difficult to meet the environmental protection standards;

[0007] (3) Adopting multi-stage large-scale mobile belt conveyors and loading and unloading vehicles for transportation, which consumes electricity and fuel, consumes a lot of energy, and the damage rate of its own equipment is also extremely high;

[0008] (4) More than 10 workers per shift, working continuously in the open air, poor working environment and high labor intensity

The weight of the whole machine is 76.4 tons, and the length of the cantilever arm is similar; however, the disadvantage is that it can only rotate along a semicircular arc within the range of ±90° on the fixed point, and cannot realize large-scale and long-distance material transportation;

[0010] If a traditional stocker is used, such as the double-arm stocker designed by Wuhan Iron and Steel Design Institute (see figure 2 ), the stacker can move back and forth along the track; however, the arms cannot be rotated, and the material drop point is on both sides of the track, and the material can only be distributed along two straight lines. Large-scale site stacking requirements
