Comprehensive assessment platform device for elevator pit

Abstract

The invention relates to the technical field of elevator teaching equipment, and discloses a comprehensive assessment platform device for an elevator pit, the comprehensive assessment platform device comprises a lift car, a shaft and a pit area, and the bottom of the pit area can be lifted at the bottom of the lift car; a barrier is arranged on one side above the bottom pit area, and a linkage adjusting assembly is arranged between the bottom pit area and the barrier; when the driving assembly drives the pit area to ascend and descend, the linkage adjusting assembly drives the barrier to ascend and descend in the same direction and in different directions. The bottom plate is driven by the lifting mechanism to move, the space in the pit area is changed by adjusting the linkage adjusting assembly in a matched mode, data of the space in the pit area are made to be wrong, the pit data are examined by examiners about GB7588-2003 safety specifications for elevator manufacturing and installation, and then the data of the pit are examined by the examiners when the examiners are examined. The internal space of the pit area of the elevator can be detected personally, whether the internal space meets the specification or not is judged, and trainees are deepened to find and understand the structure of the elevator and the specification data of specific examples in the using process of the elevator.

Description

technical field [0001] The invention relates to the technical field of elevator teaching equipment, in particular to a comprehensive assessment platform device used for elevator bottom pits. Background technique [0002] The pit is located in the hoistway part below the bottom station of the car service, which is equipped with buffers, elevator stop switches, hoistway light switches, power sockets and lighting; pit doors can be provided as required; the pit should have enough space , The existing real elevators are vertical structures, and most of them use closed reinforced concrete structure shafts. This structure does not meet the most basic safety requirements for elevator inspection, testing, and teaching assessment; and the real elevator is a slender, vertical device. Taking a three-story elevator as an example, the highest point of operation is about 10 meters. Teachers and students are in the process of teaching assessment. Frequent climbing up and down and walking i...

Problems solved by technology

This structure does not meet the most basic safety requirements for elevator inspection, testing, and teaching assessment; and the real elevator is a slender vertical vertical device. Taking a three-story elevator as an example, the highest operating point is about 10 meters. Teachers and students are in the process of teaching assessment. It is necessary to climb up and down frequently and walk around, which not only consumes a lot of physical strength, but also wastes a lot of time during the teaching process, which is not conducive to the convenience of teaching; If students misuse, it is easy to cause safety accidents, which is dangerous; in addition, the limited space is not conducive to students' observation and operation

[0003] According to the requirements of GB7588-2003 "Safety Code for Elevator Manufacturing and Installation", there are standard specifications for the space between the protective counterweight barrier relative to the pit floor and the parts in the pit relative to the hoistway. Due to the existing teaching Assessing elevators is highly dangerous. Generally, only the dynamic operation of the elevator is carried out during teaching, and the students watch the elevator from the outside; and during the assessment, the content of the assessment is mostly theoretical assessment, resulting in poor hands-on ability of the students. The structure of the elevator itself, and There is little discovery and understanding of the specification data of specific examples in the use of elevators; further leading to the fact that students who pass the assessment need to continue to learn practical knowledge of elevators in actual work
