Problems solved by technology

[0003] However, in the above-mentioned lifting equipment of the prior art, the counterweight on it is connected to the lifting platform through the same chain, and one end of the chain is connected to the lifting platform, bypasses the sprocket, and the other end is connected to the counterweight
In this way, the lifting stroke of the counterweight is the same as that of the lifting platform, and there is a problem that the lifting space of the counterweight is limited when the lifting stroke of the lifting platform is large.

Embodiment Construction

[0018] In order to further illustrate the principle and structure of the present invention, the preferred embodiments of the present invention will now be described in detail with reference to the accompanying drawings.

[0019] The lifting equipment of the present invention can be a stacker or other commonly used lifting equipment in the field, and its basic structure is similar, so the following only takes a stacker as an example to describe its structure in detail. see Figure 1 to Figure 3 As shown, the stacker includes a frame 1 , a lifting device 2 and a counterweight device 3 arranged on the frame 1 .

[0020] The whole frame 1 is a rectangular three-dimensional frame structure, and four lifting guide columns and two counterweight guide columns 15 are vertically arranged thereon. The four lift guide columns are distributed in four corners, and are respectively defined as a first lift guide column 11, a second lift guide column (not shown in the figure), a third lift gu...

Abstract

The invention discloses lifting equipment, which comprises a machine frame and a hoisting device and a balance weight device which are arranged on the machine frame, wherein a hoisting drive mechanism in the hoisting device drives a lifting platform to lift; the hoisting drive mechanism comprises a first chain which is driven by a motor; one end of the first chain is connected to the lifting platform, while the other end rounds a chain wheel and drives the chain wheel to rotate; a balance weight drive mechanism in the balance weight device drives a balance weight to lift; one end of a second chain in the balance weight drive mechanism is connected with the balance weight, while the other end rounds an upper chain wheel arranged at the top and a lower chain wheel arranged at the bottom to be connected with the balance weight, and the upper chain wheel and the chain wheel are coaxially connected but have different tooth numbers, so that the movement journeys of the balance weight and the lifting platform are different. Thus, the problem that the lifting space of the balance weight is limited when the lifting journey of the lifting platform is large is solved.

Description

technical field [0001] The invention relates to a lifting device, in particular to a lifting device with a counterweight device. Background technique [0002] Lifting equipment is often used in hoisting operations, such as common stackers. In order to achieve the lifting function, the lifting equipment is usually provided with a lifting platform. In order to balance the lifting operation of the lifting platform, a counterweight device is also required. For example, the structure of a stacker disclosed in Chinese patent CN12251218 is provided with a lifting platform and a double counterweight mechanism matched with it. The other end of the counterweight pulley block is connected with the counterweight frame by a wire rope joint, and the wire rope joint is also equipped with a buffer spring. Slide up and down along the guide rails to balance the lift table and the weight it carries. [0003] However, in the above-mentioned prior art lifting equipment, the counterweights and ...
