Description

Quick leveling counterweight module for car

Technical Field

The utility model relates to a special equipment field specifically is a fast leveling counterweight module group for car.

Background

The counterweight is a component of the elevator traction system and functions to reduce the power of the traction motor and the torque on the traction sheave and the worm gear. The counterweight device is positioned in the hoistway and is connected with the car through a traction sheave by a traction rope. In the running process of the elevator, the counterweight device slides on the counterweight guide rail through the counterweight guide shoe to play a balancing role. The structure of the counterweight has no fixed form, but in any form, the counterweight consists of two main parts, namely a counterweight frame and a counterweight iron block. The counterweight housing is formed by welding a channel steel or a steel plate with the thickness of 3-5 mm after being folded and pressed into a channel steel shape. Due to different use occasions, the structural form of the counterweight housing is slightly different. When the rated load capacity of the ladder is different, the specifications of the section steel and the steel plate used for the counterweight housing are also different. When the straight beam of the bogie is matched with the section steels with different specifications, the counterweight iron blocks corresponding to the sizes of the notches of the section steels are required. In order for the counterweight to perform an optimal balancing function for the car, the total weight of the counterweight must be correctly calculated. The total weight of the counterweight device is related to the net weight of the elevator car and the rated load capacity of the car, so the number of the weight blocks is obtained by calculating the self weight and the rated load capacity of the car, and can be only obtained by an arbitrary number. Therefore, for the existing cars with different specifications and rated loads, the existing common counterweight iron blocks are 50kg, 75kg, 100kg, 125kg and the like, and the mode of carrying out balance adjustment by a single fixed weight has the following 2 problems.

However, for various reasons, the elevator may be additionally provided with internal decorations and facilities for many times during operation, the weight of the additional equipment and the decorations is not small, and the weight of the additional equipment and the decorations is preferably further adjusted according to the decoration adding condition, so that the difficulty and the cost of elevator maintenance are greatly increased.

On the other hand, the self weight of the weight is limited, the leveling precision cannot reach the weight below the self weight for leveling, and the leveling precision is too low. Based on the above, the smaller car cannot be matched with the counterweight blocks with heavy weight models, so that the counterweight blocks are divided into dozens of models due to different weights, and cost control is not facilitated.

Detailed Description

The present invention will be further described with reference to the following specific examples. It should be understood that these examples are for illustrative purposes only and are not intended to limit the scope of the present invention. Furthermore, it should be understood that various changes or modifications of the present invention may be made by those skilled in the art after reading the teachings of the present invention, and these equivalents also fall within the scope defined in the present application.

The counterweight iron block is made of cast iron. The counterweight iron block is specifically balanced according to different rated loads and car weights, and the mass of the counterweight is generally half of the mass of the car and the rated load, namely the mass of the car is 800kg, the rated load is 1050kg, and the mass of the counterweight is 800+525 to 1325 kg.

When the weight of the people in the elevator reaches half of the rated load capacity, the elevator is balanced with the counterweight, the tractor is most labor-saving, and the counterweight naturally descends when the elevator car ascends. Some high-end elevators also have an energy feedback technology, namely the potential energy of the elevator car or the counterweight is converted into electric energy, and the electric energy is generated when the potential energy descends. Therefore, the counterweight can balance the weight of the lift car and part of the load weight of the lift, and the power loss of the motor is reduced.

The car, including the ceiling and the walls, are of a weight that helps to save energy when the weight of the counterweight is substantially equal to the weight of the car. But the weight of the counterweight is generally heavier than the car during design. The safety accident caused by the slipping of the elevator when the brake of the elevator tractor breaks down is considered. Furthermore, the elevator of the prior art is provided with compensating chains between the car and the counterweight, which also contribute to the gravitational equilibrium between the two.

Therefore, the counterweight block plays an important role in balancing the elevator and feeding back part of the elevator, but the conventional counterweight block is limited by the dead weight of the counterweight block when the counterweight is adjusted, so that the elevator is difficult to realize better balance in operation. For example, a 100kg counterweight, further leveling of weights within 100kg is not possible. This is not conducive to balancing the elevator traction and can add wear to the elevator core traction components over long runs. Meanwhile, if the rated load of the elevator is small, the counterweight with a large weight model cannot be used for adjusting balance, so that the models of the counterweight blocks are too many, the configuration cost of the process and the related die is increased, and the modularized production is not facilitated. In addition, after the elevator car is installed in many buildings, due to the requirements of owners or developers, the car is required to be decorated, and some decoration parts such as building multimedia advertisement screens, mirrors, interior decorations and the like are additionally installed, the weight of the components cannot be ignored, but the weight of the components is difficult to realize accurate leveling through the counterweight block with heavy dead weight, and if the weight of the car after the elevator is installed is changed, the operation of construction and maintenance is very troublesome, the counterweight frame needs to be disassembled, and 50-200kg of the counterweight block needs to be carried, so that time and labor are wasted.
