Description

An elevator counterweight frame capable of installing double rows of counterweight blocks

technical field

The utility model relates to the field of elevators, in particular to an elevator counterweight frame capable of installing double rows of counterweight blocks.

Background technique

The existing elevator counterweight device includes a counterweight block and a counterweight frame. The counterweight frame includes an upper beam, a lower beam and two channel steel outer straight beams to form a square shape. Two ends of the counterweight block are snapped into two channel steels. In the groove of the outer straight beam. In order to achieve the balance factor required by the design, a number of counterweights are required, and too many counterweights will make the length of the entire device too high, because the height of the top floor of the elevator shaft is low, and it will appear during installation. Many problems; if the counterweight is too large and heavy, it will be difficult to put the counterweight into the counterweight frame during installation.

Utility model content

The beam is provided with at least one counterweight wheel, and also includes an I-shaped steel inner straight beam, the inner straight beam is arranged between two outer straight beams, and the upper end of the inner straight beam is arranged on the upper beam, so The lower end of the inner straight beam is arranged on the lower beam.

Preferably, the upper end of the inner straight beam is arranged in the middle of the upper beam, and the lower end of the inner straight beam is arranged in the middle of the lower beam; the distance between the inner straight beam and the outer straight beams on both sides is equal, and both sides can be placed with the same size counterweight.

Preferably, there are two counterweight wheels, and the two counterweight wheels are respectively arranged on the upper beams on both sides of the inner straight beam to keep the two sides in balance.

Preferably, the top of the upper beam is provided with a counterweight wheel cover plate; to prevent dust particles in the hoistway from falling between the moving counterwheels and the steel wire rope, and to protect the counterwheels.

Preferably, the bottom of the lower beam is provided with a counterweight buffer plate, which acts as a buffer when the frame body descends to the bottom.

Preferably, both the outer straight beam and the inner straight beam are provided with stoppers, and the stoppers are fixed on the straight beam by bolts; the counterweights arranged between the outer straight beam and the inner straight beam are fixed.

Preferably, the upper end of the inner straight beam is fixed on the upper beam by bolts, and the lower end of the inner straight beam is fixed on the lower beam by bolts; the bolt connection facilitates installation and disassembly.

Preferably, guide shoes are provided on the outer sides of the upper parts of the two outer straight beams, and guide shoes are also provided on the outer sides of the lower parts of the two outer straight beams; the guide shoes guide the frame.

Preferably, a backing plate is provided on the outer sides of the upper parts of the two outer straight beams, and a lubricating device is provided at the top of the backing plate to lubricate the guide shoes.

Compared with the prior art, the utility model has the advantages that the frame is divided into two spaces for placing the counterweight by using the inner straight beam, the frame does not need to be made very long, the frame is convenient to install, and the counterweight is not required It is very heavy, which reduces the labor intensity of workers when installing the counterweight. In addition, the total length of the counterweight frame is shortened, which reduces the requirements for the height of the top floor of the hoistway.
