Embodiment Construction
[0014] see Figure 1 to Figure 3 , an elevator car, including a car frame column 1, a car frame beam 3, a reverse sheave 4, a shaft 5 and a connecting part 6.
[0015] The two upper beams 3 are connected with the car frame column 1 through the connecting piece 6, and the reverse sheave 4 is connected with the upper beam 3 of the car through the shaft 5. Wire rope 2 can be wound down from the hoistway top, winds on two anti-rope pulleys 4 by the space between two upper beams 3, and then winds back to the hoistway top.

A cage of elevator features that two rope pulleys are fixed via axles to the transverse beam on the top of cage. Its advantages are large free space, high vibration damping effect, and shallow depth of bottom pit. The invention can be used for towing radio 2:1 elevator.
Description
technical field [0001] The invention relates to a car of a traction elevator, in particular to an elevator car with a traction ratio of 2:1. Background technique [0002] The car is the part used to take people or carry goods in the elevator. In an elevator with a traction ratio of 2:1. Most of the existing car structures adopt the structure of a single anti-sheave, such as Figure 4 As shown, the anti-sheave is installed in the middle part of the car top. Or place two anti-rope pulleys obliquely on the bottom of the car, such as Figure 5 shown. There are also two anti-rope pulleys installed in parallel at the bottom of the car (see Figure 6 ). [0003] The car structure with a single anti-rope pulley will reduce the maintenance space of the machine room, which is not conducive to maintenance operations; when the elevator running speed exceeds 2m / s, the structure of the anti-rope pulley at the bottom of the car is not good for vibration reduction of the elevator car; ...
