[0002] The concrete counterweight lifting device for photovoltaic construction is a device used to install photovoltaic power stations. It is usually composed of hydraulic systems, brackets, counterweights and other components. Its function is to lift the concrete counterweight to the required height through the hydraulic system, and then install the counterweight on the photovoltaic bracket to increase the stability and load-bearing capacity of the bracket. This device can help photovoltaic power stations complete installation quickly and safely, and improve the stability and safety of the photovoltaic system.

[0003] Among them, it was found through search that the utility model patent with patent application number CN202120720160.9 discloses a photovoltaic bracket lifting mechanism, including a bracket lifting machine installed on a bracket base, the top end of the bracket lifting machine forms a detachable connection with the photovoltaic bracket, and the bracket lifting machine includes a transmission mechanism with a self-locking function, and a travel mechanism connected to the transmission mechanism. When the transmission mechanism is started, the bracket lifting machine is used to lift the photovoltaic bracket to a predetermined height.

[0004] When this structure is in use, there is no need to disassemble or assemble the photovoltaic modules and the bracket during the lifting process of the entire bracket, which not only avoids damage to the modules and the bracket during operation, but also greatly reduces the workload and labor costs of the lifting operation.
