Problems solved by technology

The traditional elevator counterweight frame consists of two left and right columns and upper and lower beams. The counterweight anti-rope pulley is installed on the upper beam of the counterweight frame. The upper beam needs to have load-bearing and specification requirements, and the cost is relatively high; when installing the counterweight When the counterweight and anti-rope pulleys hinder the installation operation, it is difficult to install the counterweight; when the height of the top layer of the hoistway is small, in order to meet the operation stroke requirements of the counterweight device, the counterweight structure can only reduce the distance between the two columns. length, and reduce the number of counterweights, but this will cause the total weight of the counterweight device to fail to meet the balance requirements of the elevator
In addition, in order to save the space of the hoistway in the traditional elevator, the guide wheel and the counterweight anti-sheave are usually arranged vertically in the hoistway plane design, and the traction wire rope needs to be installed with twists. In order to solve the above situation, it is necessary to improve the structure of the existing counterweight device

Abstract

The invention provides a collet counterweight device of an elevator and a counterweight mounting structure applying the same. The collet counterweight device comprises a counterweight rack, a counterweight group, a counterweight diversion sheave, a counterweight weight, a counterweight guide shoe and an oil cup. A bearing beam is arranged below the counterweight rack, and a plurality of counterweight cavities are formed above the bearing beam; the counterweight group is arranged in each counterweight cavity; the counterweight weight is detachably and slidably arranged on the counterweight rackfor compressing the counterweight group; and the counterweight diversion sheave is arranged below the counterweight rack. The demand on the beam on the counterweight rack is reduced, the cost is lowered, the counterweight mounting space in the counterweight rack can be utilized effectively and fully, and meanwhile, it is convenient to mount and detach the counterweight group. A condition that a traction steel wire rope and a steel wire wheel are separated in the counterweight mounting structure can be prevented effectively.

Description

technical field [0001] The invention relates to the technical field of elevator counterweight devices, in particular to a bottom bracket type counterweight device of an elevator and a counterweight installation structure using the same. Background technique [0002] The counterweight is an integral part of the elevator traction system. Its function is to balance the weight of the car itself and part of the elevator load weight, while reducing the power of the traction motor and the torque on the traction wheel or worm wheel. The counterweight device is located in the hoistway, and the car is connected by the traction wire rope through the guide wheel and the traction wheel. During the operation of the elevator, the counterweight device slides on the counterweight guide rail through the counterweight guide shoe to play a balancing role. The traditional elevator counterweight frame consists of two left and right columns and upper and lower beams. The counterweight anti-rope pu...
