Elevator car device

Abstract

The invention discloses an elevator car device. The elevator car device comprises an elevator car frame, a car bottom frame, an elevator car and diversion sheave devices. The elevator car frame comprises an upper beam, a vertical beam and a lower beam. The car bottom frame comprises a car bottom rear beam, car bottom edge beams and a car bottom front beam. Each diversion sheave device comprises a clamping plate, a sheave shaft and a diversion sheave. The car bottom frame is fixedly connected to the lower beam. The elevator car is fixedly connected to the car bottom frame. The two car bottom edge beams are correspondingly and fixedly connected with the two diversion sheave devices. The two diversion sheave devices are correspondingly arranged on the two sides of the lower beam. The diversion sheaves of the two diversion sheave devices are located in the same plane in the radial direction. The diversion sheaves are at least partially overlapped with the lower beam in the mounting height direction. By the adoption of the elevator car device, the depth of a pit required by an elevator is lowered greatly, and meanwhile it can be guaranteed that the elevator operates stably.

Description

technical field [0001] The invention relates to the field of elevators, in particular to an elevator car device. Background technique [0002] The reverse rope pulley is a kind of movable pulley applied to the elevator, usually set on the car and the counterweight frame. According to needs, the traction rope can bypass the anti-sheave to form different traction ratios, and its function is to reduce the output power and torque of the traction machine. [0003] The anti-sheave device installed at the bottom of the car in the prior art generally includes two vertical splints on the left and right, the sheave shaft rotatably connected in the left and right splints, and the anti-sheave wheel installed on the sheave shaft. The top of the roof is fixedly connected to the lower surface of the lower beam in a stacked manner. This installation method does not overlap the vertical anti-rope pulley and the lower beam, and requires an additional height to install the anti-rope pulley, r...

[0003] The anti-sheave device installed at the bottom of the car in the prior art generally includes two vertical splints on the left and right, the sheave shaft rotatably connected in the left and right splints, and the anti-sheave wheel installed on the sheave shaft. The top of the roof is fixedly connected to the lower surface of the lower beam in a stacked manner. This installation method does not overlap the vertical anti-rope pulley and the lower beam, and requires an additional height to install the anti-rope pulley, resulting in a high pit depth for the elevator.
