[ field of technology ]
The utility model relates to an adjustable combined weight for a hoist test, and belongs to the technical field of hoist dynamic load and load limiting tests.
[ background Art ]
In the existing load-limiting hoist simulation test device with the patent number of 201921509051.1, a plurality of main weights 8 are used, before dynamic load performance and load-limiting performance are tested, the main weights 8 are required to be fixed on the lower section of the lifting boom 6 block by block in a manual mode, so that the main weights 8 are stacked together along the height direction, and the lower section of the lifting boom 6 is located in the ground hole R.
Careful analysis of the main weight 8 structure and its stack structure, it was not difficult to find that the following technical deficiencies existed:
1. in order to meet the test requirements of the load-limiting hoist with different rated loads, the number of the main weights 8 of the combined structure stacked together is different, and the excavation depth of the hole R is larger, so that the construction cost is higher;
2. because the main weights 8 are required to be fixed block by block manually, the labor is wasted and the test preparation work efficiency is low.
[ utility model ]
Aiming at the defects of the prior art, the utility model aims to provide an adjustable combined weight for a calabash test.
Therefore, the utility model provides the following technical scheme:
the utility model provides an adjustable combination's weight for hoist test, supplies rated load to be 0.25t, 0.5t, 1t and 2 t's hoist dynamic load, limit for load test use, its improvement point lies in: the weight I is arranged in the middle, the weight II is sleeved with the weight I in an empty mode, the weight III is sleeved with the weight II in an empty mode, the weight VI is sleeved with the weight III in an empty mode, the top of the weight I is provided with a pin hole a for plugging, the tops of the weight II, the weight III, the weight VI and the weight V are symmetrically provided with pin holes b, pin holes c, pin holes d and pin holes e for plugging respectively, and the pin holes a, the pin holes b, the pin holes c, the pin holes d and the pin holes e can be selectively pulled out after all the weights are plugged.
Compared with the prior art, the utility model has the following advantages and positive effects:
the sleeve-type structural weight is beneficial to reducing the pit depth and the building construction cost;
after five weights of the sleeve structure are provided with pin holes, a pluggable matching structure can be formed by weighing rods and weights of corresponding quantity of lifting tool parts, when all weighing rods and all weights are correspondingly and fully plugged, pneumatic clamping elements of the pluggable parts can selectively control less than all the elements to be clamped with the weighing rods of corresponding quantity, and then a servo motor drives a cylinder to return stroke in the pluggable parts, so that the non-taking weights are separated from the plugging state of the corresponding weighing rods, namely, free combination adjustment of the quantity and the weight of the lifting weights is realized, and therefore, the practical lifting load required by the load limiting and dynamic load test of the hoist on the same set of testing device is respectively met.

[ detailed description ] of the utility model
Referring to fig. 1 and 2, an adjustable combined weight for testing a hoist is provided for testing the dynamic load and the load limitation of the hoist with rated loads of 0.25t, 0.5t, 1t and 2t, and the improvement points are as follows: the weight I1 is positioned in the center, the weight II2 is sleeved with the weight I1, the weight III3 is sleeved with the weight II2, the weight VI4 is sleeved with the weight III3, the weight V5 is sleeved with the weight VI4, the top of the weight I1 is provided with a pin hole a10 for plug connection, and the tops of the weight II2, the weight III3, the weight VI4 and the weight V5 are symmetrically provided with pin holes b20, c30, d40 and e50 for plug connection, and the pin holes a10, b20, c30, d40 and e50 are selectively pulled out after all the pin holes are plug connected.
The spreader part is shown in fig. 3 and comprises nine weighing bars, namely one weighing bar a31, two weighing bars b32, two weighing bars c33, two weighing bars d34 and two weighing bars e35, wherein the weighing bar a31 is arranged centrally, and the weighing bars b32, c33, d34 and e35 are arranged symmetrically and in sequence and in an expanding manner on both sides of the weighing bar a 31. Wherein,
the weighing rods a31 and the pin holes a10 are in corresponding positions and can be mutually matched in a pluggable manner;
the weighing rods b32 and the pin holes b20 are in corresponding positions and can be in pluggable fit with each other;
the weighing rods c33 and the pin holes c30 are in corresponding positions and can be in pluggable fit with each other;
