[0027] Load testing device, such as Figure 1 and Figure 3 As shown in the figure, it includes test platform 1, hanger and lifting lug 2, test platform 1 is horizontally arranged; two pairs of hangers are arranged transversely along test platform 1; two pairs of hangers are symmetrically arranged about the middle region of test platform 1; test platform 1 is divided into middle load area 1A located in the middle of two pairs of hangers and end load area 1B located at both ends of middle load area 1A along the transverse direction of test platform 1.

[0028] The hanger includes hanger rod 3, inclined rod one 4 and inclined rod two 5, inclined rod one 4 and inclined rod two 5 form inverted V shape, the top end is connected together, the bottom end is connected to the front and back sides of test platform 1 along the longitudinal direction of test platform 1, that is, inclined rod one 4 is connected to the back side of test platform 1 along the width direction of test platform 1, and inclined rod two 5 is connected to the front side of test platform 1 along the width direction of test platform 1. Hanger rod 3 is vertically arranged at the top of the inverted V-shaped frame formed by inclined rod one 4 and inclined rod two 5, and lifting hole one 31 is arranged on hanger rod 3.

[0029] The load testing device disclosed by the utility model, test platform 1 is designed with reference to the hoisting capacity of the commonly used hoisting machine tool. Two pairs of hangers are arranged transversely along test platform 1, which means that one pair of hangers is arranged on the left side of test platform 1 along the length direction of test platform 1, and the other pair of hangers is arranged on the right side of test platform 1. The two pairs of hangers are symmetrically arranged about the middle region of test platform 1, which means that the distance from the left hanger to the left end of test platform 1 is equal to the distance from the right hanger to the right end of test platform 1. When the vertical hoisting force acting on the two pairs of hangers is equal, test platform 1 can be hoisted in a horizontal state, ensuring the stable hoisting of test platform 1. Test platform 1 is used for carrying hoisting objects. The load demand of hoisting facility load testing is adjusted by increasing or decreasing hoisting objects on test platform 1. Since the area of test platform 1 is increased, hoisting objects are directly placed on test platform 1. By moving the hoisting objects, the center of gravity of test platform 1 after carrying objects can be adjusted, the stable hoisting state of test platform 1 can be quickly adjusted, and the stable hoisting of test platform 1 can be ensured.

[0030] The arrangement of middle load area 1A and end load area 1B can better adapt to hoisting objects of different lengths. For example, hoisting objects that can be directly placed in middle load area 1A can be directly placed in middle load area 1A for hoisting test. When the hoisting object is too long and the hoisting equipment or other structures beside middle load area 1A interfere with the hoisting object, the hoisting object can be distributed in end load area 1B at both ends for hoisting test, which has higher adaptability.

[0031] In order to facilitate the connection of inclined rod one 4 and inclined rod two 5 with test platform 1, lifting lug 2 is arranged on the front and back sides of each hanger rod 3 along the longitudinal direction of test platform 1, as shown in Figure 2As shown, the hanger 2 is provided with a hanger hole two 24 for connecting with the diagonal rod, and the hanger 2 is fixed to the test platform 1; the bottom end of the diagonal rod one 4 is connected to the rear hanger 2, and the bottom end of the diagonal rod two 5 is connected to the front hanger 2.

The oblique rod two 5 is a single plate, which saves materials and is lighter in weight. Compared with the traditional two-rod top end hinged structure, the oblique rod two 5 is not hinged to the top end of the oblique rod one 4 in the embodiment, the length of the oblique rod two 5 is shortened, and the support strength of the single plate is ensured. The Y-shaped head 41 and the rod part 42 of the oblique rod one 4 form an integral whole, and the connection with the boom 3 is firm and reliable.
