Elevator pit with good ventilation performance

Abstract

The invention relates to an elevator pit with good ventilation performance, and belongs to the field of elevators, the elevator pit comprises a pit body, the pit body comprises a pit bottom and a side wall located at the edge of the pit bottom and in an enclosed shape, the side wall is concaved inwards to form a ventilation groove, the lower end of the ventilation groove abuts against the pit bottom, and the lower end of the ventilation groove abuts against the pit bottom. The upper end of the ventilation groove extends out of the side wall, the ventilation groove and the vertical direction are arranged in an inclined mode, an included angle is formed between the ventilation groove and the vertical direction, the depth of the ventilation groove is gradually reduced from top to bottom, and an exhaust fan with the air outlet direction downward along the ventilation groove is arranged at the upper end of the ventilation groove. The ventilation grooves are obliquely formed in the clockwise direction or the anticlockwise direction. The elevator has good ventilation performance, the stuffiness feeling of maintenance personnel can be effectively eliminated, it is guaranteed that the working state of the maintenance personnel is good, and then the quality of elevator maintenance operation of the maintenance personnel is guaranteed.

Description

technical field [0001] The invention relates to the field of elevators, in particular to an elevator pit with good ventilation. Background technique [0002] Elevator refers to a permanent transportation device that serves several specific floors in a building, and its car runs on at least two rows of rigid rails perpendicular to the horizontal plane or with an inclination angle of less than 15° to the plumb line. [0003] In order to ensure the long-term safe and normal operation of the elevator, the elevator needs to be repaired and maintained frequently or regularly. During the repair and maintenance process, the maintenance personnel will inevitably enter the elevator pit for operation, and the operation time is generally long, and the current elevator bottom The ventilation of the pit is poor, and the maintenance personnel need to work for a long time in a hot environment. The uncomfortable working environment will affect the mental and physical state of the maintenance...

Problems solved by technology

[0003] In order to ensure the long-term safe and normal operation of the elevator, the elevator needs to be repaired and maintained frequently or periodically. During the repair and maintenance process, the maintenance personnel will inevitably enter the elevator bottom pit to carry out operations, and the operation time is generally longer. The ventilation of the pit is poor, and the maintenance personnel need to work for a long time in a stuffy environment. An uncomfortable working environment will affect the mental state and physical state of the maintenance personnel, which will affect the working status of the maintenance personnel, and may cause maintenance decline in quality
