Problems solved by technology

In this scheme, the belt tensioning device layer is often partially set up separately as an interlayer, which destroys the regularity of the structure and easily forms "short columns" to be avoided in the seismic design, which is often unfavorable to the overall calculation of the main factory building structure
In addition, the falling of the heavy hammer to the floor will not only cause a large impact load and increase the structural volume, but also easily cause more serious injuries

Abstract

The invention relates to a main power house with same-layer arrangement of a coal conveying belt, a counter weight and a trolley-type tensioning device. The main power house comprises a belt layer roof structure, a belt layer floor structure, the coal conveying belt, a roller, the trolley-type tensioning device, a fixed pulley set, the counter weight and a pulling cable, wherein the coal conveyingbelt is wound around a tensioning roller of a trolley of the trolley-type tensioning device, the pulling cable with the counter weight fixed at one end is wound around the fixed pulley set, the otherend of the pulling cable is fixed on the tensioning trolley, the trolley-type belt tensioning device and the counter weight are arranged in the same layer, a belt layer floor does not need to be opened a hole, a single belt tensioning device layer does not need to be arranged, and the structural integrity is better; and a safety rope and an emergency fixing component are additionally arranged, sothat the control is more flexible, and the operation safety is improved on the basis of saving space.

Description

Technical field [0001] The invention relates to the technical field of transmission and tensioning of the main building of a thermal power plant, in particular to a main building with a heavy hammer car-type tensioning device for a coal conveying belt arranged on the same floor. Background technique [0002] In the conventional layout scheme of the main powerhouse of a thermal power plant, the coal conveying belt that feeds coal into the coal scuttle is arranged in the coal conveying belt layer. Since the coal conveying belt of this layer needs to send coal to multiple coal scuttles, the length of the belt is generally longer. long. In order to ensure that the conveyor belt has sufficient tension to prevent the conveyor belt from slipping on the drum, and to ensure that the belt conveyor can work normally, it is usually necessary to install a vertical weight tension device in the middle of the belt, which requires a belt tension device below the belt layer. The layer is used for...
