The invention discloses a counterweight device for a tower, and belongs to the field of marine machinery. The counterweight device for the tower comprises a tray, a connecting shaft and at least one balancing weight, wherein one end of the connecting shaft is vertically connected to the center of the tray; the other end of the connecting shaft is provided with a connecting structure used for beingconnected with a steel wire rope; at least one mounting groove is formed in the connecting shaft at intervals in the length direction of the connecting shaft; a first through hole and a strip-shapedthrough groove are formed in the balancing weight; the first through hole is formed in the center of the balancing weight; one end of the through groove communicates with the first through hole; the other end of the through groove extends to the edge of the balancing weight; the size of the first through hole is larger than the size of the cross section of the connecting shaft; the size of the through groove is larger than the size of the mounting groove; the size of the through groove is smaller than the size of the cross section of the connecting shaft; and the width of the mounting groove is larger than the thickness of the balancing weight.
Description
technical field [0001] The invention relates to the field of marine machinery, in particular to a counterweight device for a tower. Background technique [0002] Marine deck machinery such as windlasses, winches, high-performance large-scale tractors, high-power hydraulic motors and other equipment need to be subjected to load tests in order to ensure their performance. Taking the winch as an example, the load test is to evaluate the load performance of the winch by passing the cable of the winch around the pulley at the top of the tower and connecting it to the configuration device, and controlling the winch to pull to the configuration device. [0003] The existing counterweight device comprises a chassis and a counterweight, and the counterweight is placed on the chassis, and then hoisted by connecting the chassis with wire ropes. [0004] In the process of realizing the present invention, the inventor finds that there are at least the following problems in the prior art...
