Counterweight frame structure of goods elevator

Abstract

The invention relates to a counterweight structure of a goods elevator. The counterweight structure comprises a counterweight frame, wherein a counterweight wheel is mounted at the top of the counterweight frame through a connecting piece. The counterweight frame structurally comprises two vertically-supported counterweight side beams, wherein upper side plates are arranged at the upper parts of the counterweight side beams; a plurality of bolt holes are formed in two sides of the upper side plates; a lower side plate is arranged at the lower part of the counterweight frame; a plurality of bolt holes are formed in two sides of the lower side plate; a counterweight block pressing plate is arranged in the middle of the counterweight frame; and a group of counterweight frames are adjacently connected in parallel, are respectively fastened and connected with the counterweight wheel and the upper side plate through an upper connecting plate at the top of the counterweight frame and are fastened and connected with the lower side plate through a lower connecting plate at the lower part of the counterweight frame. According to the counterweight frame structure disclosed by the invention, due to the adoption of a split structure and a structure mode of adjacently connecting the counterweight frame in parallel and combining to form a whole, the counterweight frame structure is simple in structure and convenient to mount and manufacture; the defect that the mass of the counterweight frame is great because the counterweight guide rail gauge is required to be increased in the prior art is overcome; and the counterweight frame structure is convenient and simple in manufacturing and mounting and low in cost.

Description

technical field [0001] The invention relates to the field of freight elevators, in particular to a freight elevator counterweight frame structure for improving the structure and installation difficulty of the large-tonnage freight elevator counterweight frame. Background technique [0002] The freight elevator counterweight is a device to balance the weight of the freight elevator car. Usually, the freight elevator is equipped with a certain counterweight to balance the weight of the freight elevator and the load, so as to reduce the burden on the driving equipment. The frame carrying this counterweight is the counterweight frame. [0003] Traction counterweight devices are often used in the prior art, and profiles are generally used as the counterweight frame. In a 2-3 ton freight elevator, when the load of the freight elevator increases, if it is applied to a 5 ton freight elevator, if the counterweight frame in the prior art is still used, it will not be able to be used ...

[0003] Traction counterweight devices are often used in the prior art, and profiles are generally used as the counterweight frame. In a 2-3 ton freight elevator, when the load of the freight elevator increases, if it is applied to a 5 ton freight elevator, if the counterweight frame in the prior art is still used, it will not be able to be used normally due to the limitati
