[0026] Please refer to Figure 1-Figure 3 , which is a schematic diagram of the structure of the pure iron special weight in the embodiment of the utility model;

[0027] The present embodiment provides a pure iron special weight, including a pure iron weight block 1 in a rectangular shape, a positioning groove 11 is provided at the bottom of the pure iron weight block 1, and a positioning block 12 is provided at the top of the pure iron weight block 1, and the positioning block 12 is adapted to the positioning groove 11; at least one group of hanging grooves 13 are provided on the opposite side walls between the top and the bottom of the pure iron weight block 1, and a hanging ear 14 is provided in the hanging groove 13, and the distance between the end of the hanging ear 14 and the bottom of the hanging groove 13 is less than the depth of the hanging groove 13.

[0028] Next, the pure iron dedicated weight of this exemplary embodiment will be further described.

[0029] In some embodiments of the present application, the above-mentioned pure iron weight block 1 is made of pure iron material and made of a rectangular structure, which is formed by flat welding of the internal pure iron plate and the outer shell iron plate covering and welding. This is not only neat and beautiful, but also the number of iron plates can be set according to the needs to adjust the weight of the pure iron weight block to the required weight, and there is no need to open a mold, which avoids the expensive mold opening cost of the casting weight set, avoids the breakage of the casting counterweight, and improves the service life of the weight. And the pure iron material is used, preferably pure iron Q235B, with a density of 7.85 tons / cubic meter, high density and small volume, which compresses the production volume of the filling weight set. The volume of the same weight weight is 10% smaller than that of the cast iron weight, which optimizes the limitations of using the weight set in a narrow space.

[0030] In some embodiments of the present application, a positioning groove 11 is provided at the bottom of the above-mentioned pure iron weight block 1, and a positioning block 12 is provided at the top of the pure iron weight block 1, and the positioning block 12 is adapted to the positioning groove 11; by providing the positioning groove 11 and the positioning block 12 to be adapted and connected, when multiple pure iron weight blocks 1 are stacked and combined, the pure iron weight blocks 1 are closely matched with each other, and the locking of the positioning groove 11 and the positioning block 12 is safe and reliable, with high stability, and the weight block is prevented from slipping due to the groove. And by adopting the above structure, the pure iron weight block 1 can be set to different specifications, and can be arbitrarily matched and combined to meet the needs of cranes of different tonnages.

[0031] As a preferred implementation, the weight of the above-mentioned pure iron weight block 1 is 1 ton, 5 tons or 10 tons. For example, one 5-ton weight block is set, twelve 10-ton weight blocks are set, 10*12+5=125 tons, multiple groups are matched and interchanged, and the scalability is strong; it can be expanded according to demand in the later stage to meet the weight required for different working conditions, fully verify each lifting link of the equipment, and the load test data can be obtained in a single time, further improving the work efficiency.

[0032] In some embodiments of the present application, at least one set of hanging grooves 13 is provided on the opposite side walls between the top and the bottom of the pure iron weight block 1, and a hanging lug 14 is provided in the hanging groove 13, and the distance between the end of the hanging lug 14 and the bottom of the hanging groove 13 is less than the depth of the hanging groove 13. The design of the hanging groove 13 fully considers that the weight hanging lug 14 does not affect the total width of the weight, which is convenient for lifting and transportation, and avoids the problem that the hanging lug 14 is exposed to increase the overall width of the weight, resulting in inconvenience in transportation.

[0033] Preferably, the above-mentioned hanging grooves 13 and hanging ears 14 are arranged in two groups, and the two groups are arranged at intervals on the side wall of the pure iron weight block 1, so that the stability is higher during the lifting process and falling due to large shaking is avoided.

[0034] As a preferred embodiment, the hanging grooves 13 on opposite sides of the pure iron weight block 1 are symmetrically arranged, and the hanging ears 14 are fixed in the pure iron weight block 1, and the two ends of the hanging ears 14 are respectively located in the corresponding hanging grooves 13. By setting the hanging ears 14 to penetrate the entire pure iron weight block 1, the overall bearing strength during hoisting is guaranteed.

[0035] As a preferred embodiment, the above-mentioned lifting lug 14 is cylindrical, the end of the lifting lug 14 is a stepped cylinder, and the diameter of the end away from the pure iron weight block 1 is larger than the diameter of the end close to the pure iron weight block 1. By setting the end of the lifting lug 14 as a stepped cylinder, the cylinder can fully protect the hoisting rope and will not cause damage to the rope. The problem of rope falling off and rope damage caused by edges and corners in the traditional C-type lifting lug 14 is avoided.

[0036] As a preferred embodiment, the surface of one side of the pure iron weight block 1 provided with the positioning block 12 is provided with an anti-slip layer 15. The anti-slip layer 15 is made of a mixture of quartz sand and a binder.

[0037] It should be noted that the top surface of the traditional weight block is painted blue. When the weight is assembled, the construction workers will walk on the weight surface when hanging the rope, which may cause the risk of slipping. Therefore, the anti-slip layer 15 made of black adhesive and 80 mesh quartz sand is selected to improve the anti-slip effect. The anti-slip layer 15 is durable and ensures the safety of construction workers walking on the weight surface.

[0038] As a preferred embodiment, the width of the above-mentioned pure iron weight block 1 is less than or equal to 2.2m. Specifically, the size of a 5-ton pure iron weight block is: length × width × thickness = 1.8m × 1.8m × 0.21m; the size of a 10-ton pure iron weight block is: length × width × thickness = 2.2m × 3m × 0.2m. The volume of the traditional weight block is greatly compressed, meeting the requirements of various transport vehicles not to exceed the width or height.

[0039] The embodiment of the present application also provides a pure iron special weight set, including multiple pure iron weight blocks 1 as described above, multiple pure iron weight blocks 1 are stacked, and the positioning block 12 of any pure iron weight block 1 is inserted into the positioning groove 11 of the pure iron weight block 1 adjacent to its top.

[0040] The weight group can be combined according to the weight that the lifting equipment needs to measure, so that the total tonnage of the weights matches the test tonnage. The combination follows the orderly stacking method of large supporting small. By adjusting the number of pure iron weight blocks 1, it is used to verify the lifting capacity of the lifting equipment and realize lifting tests of different weights.

[0041] As a preferred embodiment, the weight set includes a plurality of stacked 10-ton pure iron weight blocks 1 and at least one 5-ton pure iron weight block 1 , wherein the 5-ton pure iron weight block 1 is located on top of the 10-ton pure iron weight block 1 .

[0042] There are thirteen pure iron weight blocks 1 (one for 5 tons and twelve for 10 tons). Each pure iron weight block 1 can be hoisted separately and can be hoisted at one time after combination. There is no need to use special hoists or hangers separately. 10*12+5=125 tons of multiple groups are matched with interchangeable combinations (which can be expanded later) to meet the weight required for different working conditions, fully verify each lifting link of the equipment, and load test data can be obtained in a single time, further improving work efficiency.

[0043] Beneficial effects:

[0044] The pure iron weight set is easy to transport and store. It requires a small volume for easy storage and a weight suitable for general vehicle transportation. The weight set is suitable for cranes of different tonnages. The weight blocks are versatile and have different specifications, which are convenient for combination and use, and there is no need to design a counterweight bracket separately. At present, 1 to 50 tons can be combined at will, with strong scalability. It can be upgraded to 100-200 tons in the future. The height after combination is low, which meets the test requirements and improves work efficiency. During the load test, all load data should be measured in a single stroke as much as possible.

[0045] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. For those skilled in the art, the present invention may be subject to various modifications and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
