Gantry type circular stockyard material piling and taking machine

Abstract

The invention provides a gantry type circular stockyard material piling and taking machine which comprises a circular track, a travel trolley, a gantry, a follow-up device, a top frame and a rolling friction pair. The travel trolley runs along the circular track; one end of the gantry is rotatably connected to the center of the circular track, the other end of the gantry is movably connected with the travel trolley, and the gantry can be driven by the travel trolley to rotate around the center of the circular track; the follow-up device is arranged between the travel trolley and the gantry and comprises a support, and the lower end of the follow-up device is connected onto the travel trolley; the top frame is arranged above the support and is connected onto the gantry; the rolling friction pair is arranged between the support and the top frame, and the movement direction of the rolling friction pair is consistent with the radial direction of the circular track. The gantry type circular stockyard material piling and taking machine has the advantages that the rolling friction pair can bear high load, and deformation of the gantry can be sufficiently relieved.

Description

technical field [0001] The invention relates to the field of gantry stackers and reclaimers, in particular to a gantry type circular stockyard stacker and reclaimer. Background technique [0002] The stacker and reclaimer used in the round coal site is covered by the hemispherical coal tank shell. During the stacking and reclaiming operation, it is concentrated within the gyration range of the centering rotation, and is not affected by bad weather such as typhoons, and the dust generated at the same time is small. . Therefore, it solves the large-scale pollution of the surrounding environment caused by a large amount of dust generated by the stacker-reclaimer in the conventional open strip coal yard. The stacking and reclaiming equipment used in the round coal site is generally a round stacker and reclaimer. [0003] The circular stacker-reclaimer is composed of three parts: the stacker, the reclaimer and the central column. The stacker and the reclaimer do not interfere w...

Problems solved by technology

[0006] Therefore, the technical problem to be solved by the present invention is to overcome the insufficient pressure bearing capacity of the follower device between the gantry and the walking trolley in the gantry-type circular stockyard stacker-reclaimer of the prior art and the problem of being easily stuck. , so as to provide a gantry-type circular stockyard stacker-reclaimer with a follow-up device that can withstand a large load and can be applied in an environment with a large dust concentration
