Problems solved by technology

The disadvantages of using cement or cast iron test weights as static test loading loads are: one, after completing the static test, due to the large total weight of the test weights used for the static test, hundreds of tons, or even thousands of tons cement or cast iron test weights, the hoisting and transshipment workload during hoisting storage and re-testing is large; second, making hundreds of tons, or even thousands of tons of cement test weights or cast iron test weights, consumes a lot Third, the place occupied by the cement or cast iron test weights of hundreds of tons or even thousands of tons is large, which is not convenient for storage, especially when centralized storage, the load on the ground of the storage place is large , it is necessary to set up a special storage place to meet the load, which increases the construction cost of the storage place
The defects of using cement test weights or cast iron test weights as static test loads have always plagued the normal conduct of static tests of bridge cranes, and even made it difficult to carry out static tests, seriously affecting the operation safety of bridge cranes

Embodiment 1

[0035] Example 1, see Figure 1 to Figure 3 . include:

[0036] Water tank 1, the top of the tank 1 or the upper end of the side wall is provided with a water inlet 1a, the bottom wall of the tank or the lower end of the side wall is provided with a drain 1b, and multiple water tanks for static tests can be stacked Collection and storage, the drain outlet 1b shown in the figure is located on the bottom wall of the box; the water tank 1 box can be a downward cone type square structure or a downward cone type circular structure, and the figure is a downward cone type square structure; the box body The square lower cone or circular lower cone structure made of plates, the opening at the upper end is the water inlet 1a, and the plates for making the box can be metal materials or engineering plastics, etc.; the open part of the upper end of the box can also be set Removable case lid.

[0037] Assembled support frame 2, the assembled support frame 2 is a detachable structure,...

Embodiment 2

[0042] Example 2, see Figure 4 , Figure 5 . The main difference with embodiment 1 is that the water tank 1 casing is a vertical wall structure.

[0043] The water tank 1 is provided with a water inlet 1a on the top or the upper end of the side wall, and a water outlet 1b is provided on the bottom wall or the lower end of the side wall. A plurality of the water tanks used for static tests can be collected and stored in a stackable manner. , The illustrated drain port 1b is located on the bottom wall of the box. The tank body of the water tank 1 can be a vertical wall-type square structure or a vertical wall-type circular structure, the tank body is made of a pentahedron or a cylinder and a bottom wall structure, and the opening at the upper end is the entrance. Nozzle 1a, the plate for making the box body can be metal material or engineering plastic, etc., and the upper part of the outer wall surface of the box body wall is provided with lifting lugs 1d for lifting.

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...
