Abstract

The invention relates to the field of test and detection of bridge type cranes and in particular relates to a water tank type weight test block for a bridge type crane static test. A water inlet (1a) is formed in the top or the upper end part of the side wall of a tank body of each water tank (1); a water discharging port (1b) is formed in the lower end part of the bottom wall or the side wall of each tank body; a plurality of water tanks used for the static test can be collected and stored in a stacking manner; an assembling type support frame (2) is in a detachable structure; an inner cavity used for placing the water tanks is arranged in the assembling type support frame; an upper cavity opening from which the water tank can be hung in is formed in the inner cavity; water used as a load in the static test is arranged in the water tank; each side edge of the assembling type support frame is provided with a reinforced plate (6); and the inner side wall surface of each reinforced plate is provided with a rib plate (7) which can be used for preventing the side wall of each water tank from deforming after the water is filled. The material consumption and the test cost can be reduced; the weight of the empty water tank after water is discharged is light; and as the assembling type support frame is in the detachable structure, the weight of members required to be stored after the test is light, and the members can be transported and stored conveniently.

Description

technical field

[0001] The invention relates to a water tank type test weight used as a test load during the static test of a bridge crane, and is especially suitable for the static test of the bridge crane in a hydroelectric power plant (station). Background technique

[0002] The allowable working load of bridge cranes (also known as bridge cranes or bridge cranes) ranges from tens of tons to hundreds of tons. Large bridge cranes used in hydropower plants (stations) are generally more than 400 tons. The permissible working load of bridge cranes in large generating sets and power stations is generally nearly 1,000 tons, and some even exceed 1,000 tons.

[0003] The safety work regulations of relevant industries have made clear inspection and test quality standards for bridge cranes during new installation and service life. It is stipulated that a newly installed or overhauled bridge crane should be subjected to a static test, suspended for 10 minutes at 1.25 times the a...
