Description

A half-portal truss

technical field

The utility model relates to a half-portal truss gantry used in a circular stockyard, and more specifically relates to a half-portal truss, which belongs to the technical field of stacking equipment for bulk materials in a circular stockyard.

Background technique

With the increasing awareness of environmental protection and environmental protection requirements, reducing the pollution to the surrounding environment has become an urgent problem to be solved in large modern storage yards. At the same time, it is also necessary to avoid the impact of bad weather on the safe operation of the storage yard. Circular stockyard stacker and reclaimer is a kind of stacking and reclaiming equipment for bulk materials, usually arranged in circular stockyards. With economic development and social progress, environmental protection requirements are getting higher and higher. Circular stockyard stackers and reclaimers The application of feeder will be further expanded and has a good market prospect.

At present, domestic and foreign circular stockyard stackers and reclaimers mainly adopt the form of continuous herringbone stacking and full-section reclaiming. During the stacking process, the stacking arm reciprocates around the central column to achieve continuous herringbone. Stockpiling, but the reclaiming of the scraper structure is only suitable for stockyards with small reserves, low pile heights and low material viscosity, and cannot meet the needs of large reserves, high stockpile heights and high material viscosity.

In order to solve the above technical problems, the Chinese patent document CN201420655712.2 discloses a circular material yard mixing stacker and a circular material yard door type mixing stacker and reclaimer, which includes a circular material yard mixing stacker , reclaimer, gantry and pitching operation components, the circular stockyard mixing stacker includes a central column, an incoming trestle, a stacking frame body, and a stacking conveying device and a mobile unloading device are arranged on the stacking frame body Device; the stacking frame body is hinged with a stacking walking device, and the door frame is hinged with a reclaiming walking device, and both the stacker and the reclaimer are erected on the track of the retaining wall of the circular stockyard. However, the gantry used by the above-mentioned stacker-reclaimer is mainly an "A"-shaped structure, which cannot meet the requirements for the use of the movable beam of the bucket wheel machine and the belt conveyor conveyor, and cannot meet the structural requirements of the circular stockyard gantry bucket wheel stacking and reclaiming. The requirement of machine-to-machine movement limits the reclaiming production capacity of stacking and reclaiming materials. On the other hand, due to its structural reasons, the "A"-shaped gantry cannot be adjusted during the rotation process, so that in practical applications, it cannot well solve the high precision requirements for the circular track of the gantry machine's circular stockyard. And the foundation is easy to settle and deform during use.

The circular stockyard stacker-reclaimer is more and more recognized by various industries for its advanced technology, high level of program control, small footprint, large storage capacity, and outstanding environmental protection performance. Especially with the increasing capacity of ports and material transfer stations, it is extremely necessary to develop material stacking and reclaiming equipment with large (ultra-large) production capacity, strong adaptability to materials and reliable technology. . However, the gantry used in the circular stockyard cannot actually meet the needs of the circular stockyard portal bucket wheel stacker and reclaimer, which limits the reclaiming production capacity of the stacker and reclaimer.

This also constitutes the need to further improve the design of the gantry of the stacker-reclaimer to solve the existing technical problems.
