Mass trial water bag for cranes

Abstract

The invention belongs to the technical field of hoisting equipment, and relates to a mass trial water bag for cranes. The mass trial water comprises a water-drop-shaped water bag body provided with a plurality of carrying belts and closing belts. The lower ends of the carrying belts are connected to a ring arranged at the bottom of the water bag body while the upper ends of the same are closed up to be connected at one upper point of the water bag body. The closing belts are arranged along the transverse direction of the surface of the water bag body. A water inlet is arranged on the surface of the upper portion of the water bag body, and a water drain outlet is arranged on the surface of the lower portion of the water bag body. A plurality of drag points are distributed uniformly on the surface of the water bag body circumferentially. The mass trial water bag can contain 70 tons of water, and can effectively avoid shaking during use.

Description

technical field [0001] The invention belongs to the technical field of hoisting equipment and relates to a test weighing water bag for a crane. Background technique [0002] According to the relevant national norms and standards: after the crane is manufactured, transformed and the load-bearing structure or parts of the crane are repaired, the performance of the crane should be verified for the crane that is put into use for the first time. For general small gantry cranes, the counterweight is not difficult to solve, but it is a big problem for some large cranes, especially those used in remote areas, such as cranes for hydropower stations. The emergence of the test weight water bag has effectively solved the above problems. In long-term use, it is found that the existing test weight water bag also has major problems, mainly: 1. The water outlet is set at the bottom of the water bag, which has an adverse effect on the lifting of the water bag ; 2. After the water bag is fil...

Problems solved by technology

The emergence of the test weight water bag has effectively solved the above problems. In long-term use, it is found that the existing test weight water bag also has major problems, mainly: 1. The water outlet is set at the bottom of the water bag, which has an adverse effect on the lifting of the water bag ; 2. After the water bag is filled with water, even if there is only a slight shaking, due to the heavy weight, it will have a large impact on the spreader beam
