Counterweight side-falling elevator structure

Abstract

The invention discloses a counterweight side-falling elevator structure. The structure is characterized in that a traction steel wire rope enters a first counterweight rope return wheel arranged at the top end of the rear part of a counterweight through a traction machine wheel and a machine room guide wheel, enters a first counterweight guide wheel after being guided by the first counterweight rope return wheel and is horizontally and forwards transmitted into a second counterweight guide wheel, and the second counterweight guide wheel is used for ensuring that the traction steel wire rope vertically falls into a second counterweight rope return wheel arranged at the top end of the front part of the counterweight and is finally suspended to a counterweight rope head bearing beam. According to the arrangement mode, the traction steel wire rope enters the two counterweight rope return wheels arranged at the upper end of the counterweight from the adjacent side, the counterweight can move backwards by a distance equal to the diameter of the counterweight rope return wheel, so that the counterweight is placed in the middle in the front-back direction as much as possible, the counterweight is far away from a car door plate assembly located on the front side of an elevator car as much as possible, the safety space between the counterweight and a hoistway, the elevator car and the car door plate assembly is guaranteed, and even if the traction machine wheel and the machine room guide wheel are not placed obliquely, the distance between the counterweight and the car door plate assembly can be larger than the safety distance.

Description

technical field [0001] The invention relates to elevator technology, in particular to a counterweight side-drop elevator structure. Background technique [0002] The emergence of elevators greatly facilitates people to ride and transport goods, reduces manpower and improves people's work efficiency. In order to balance the load and the weight of the car, the elevator needs to be equipped with a counterweight system to reduce the load of the elevator traction system. Load, improve safety. At present, the large-load elevators used in the market are generally 2 tons, 3 tons, and 5 tons. Due to the large load, the supporting counterweight device is more than twice that of ordinary passenger elevators, but the left-right width and front-to-back depth of the shaft are Therefore, when the front and rear depths of the hoistway are insufficient, it is difficult to arrange the counterweight, which is also a problem that has plagued large-duty elevators for a long time. [0003] The ...

AI Technical Summary

Problems solved by technology

The placement position of the counterweight 4 should avoid interference with the operation of the car door panel assembly 3, the traction wheel 7 and the guide wheel 8 of the machine room above the placement position of the counterweight 4 should be placed obliquely, and the traction frame 11 should be placed obliquely on the load-bearing beam 10. Such an arrangement not only increases the difficulty of positioning the load-bearing beam 10, the traction machine and other components, but also increases the difficulty of installing the relevant components of the elevator machine room, and when the depth of the hoistway 1 is small, the traction machine is too inclined to Meet the installation conditions
