Novel side beam structure of elevator counterweight framework

Abstract

The invention discloses a novel side beam structure of an elevator counterweight framework. The novel side beam structure comprises side beams, a rope wheel assembly and a lower beam; the side beam is an integrally formed channel steel section bar; the two side beams are oppositely arranged; the lower beam is arranged between bottoms of the two side beams; the rope wheel assembly is arranged between tops of the two side beams; the side beams, the lower beam and the rope wheel assembly are connected though a fastener; and an upper counterweight block mounting hole, a middle counterweight block mounting hole and a lower counterweight block mounting hole are separately distributed in each of the two side beams. The novel side beam structure has the advantages and the beneficial effects that: the side beams do not need to bend, processing of side beams of the counterweight framework can be completed through processes such as punching, and the problems that processing difficulty is great and processing precision cannot meet requirements of a drawing in producing and processing for ultra-long side beams of the counterweight framework are solved; and upper, middle and lower counterweight block mounting holes are separately distributed in the side beams, so that the condition that one end of a counterweight block is blocked on the side beams of the counterweight framework and cannot be horizontally mounted on the bottom of the counterweight framework is avoided, and the counterweight blocks are conveniently filled, and therefore, elevator mounting speed is improved.

[0002] In the existing elevator counterweight frame, the structure of the side beam is produced by a flat plate through punching, bending and other processes. For some relatively long counterweight frame side beams, especially the high-speed ladder type counterweight For frame side beams, the required bending machine can meet the processing length is very large, the bending machine used to manufacture general ladder-type counterweight frame side beams cannot meet the processing requirements of relatively long counterweight frame side beams such as high-speed ladder type, and , There are also many difficulties in the processing of such super-long counterweight frame side beams, and the machining accuracy, especially the machining accuracy of the middle part of the side beams, is difficult to meet the requirements of the drawings. The counterweight frame side beam structure can be processed by punching and other processes

[0003] During the installation of the elevator, the counterweights are loaded after the counterweight frame is installed. Because the height of the counterweight frame is relatively high, and the counterweight mounting holes on the side beams of the existing counterweight frame are all Opened on the upper part of the side beam of the overall counterweight frame, there is great difficulty in the initial installation of the counterweight. During the installation process of the counterweight on the site, the installation workers generally put the counterweight on the counterweight In the frame, and then put the counterweight at the bottom, there is a situation that one end of the counterweight is stuck on the side beam of the counterweight frame and cannot be installed horizontally at the bottom of the counterweight frame
