[0025] Furthermore, in this embodiment, as Figure 1 As shown, the hook 2 includes a first hook 9 and a second hook 10. The first hook 9 is located at the center of the load platform 1 and is used to perform point impact and to balance the center of gravity of the load platform 1 to a certain extent. The second hook 10 is located on the outer circumferential edge of the load platform 1, and preferably there are 9 second hooks 10.

[0026] In this embodiment, as Figure 1 As shown, a fixing part 4 is also provided on the load platform 1. The fixing part 4 is used to fix the load platform 1 to the lifting device, thereby lifting the load platform 1 and the heavy object suspended on the load platform 1 to a certain height to achieve impact. The lifting device of the test device provided in the specific embodiment of this application is on the inner mast crossbeam of the test device itself. The test device is usually a forklift of various types. Fixing the load platform 1 to the inner mast of the forklift itself can realize the self-lifting of the heavy object by the test device, making the test more convenient to complete the test and inspection, without the need for other external vehicles to cooperate in the operation, thus making the test more time-saving and labor-saving.

[0027] Furthermore, in this embodiment, as Figure 1 As shown, there are two fixing parts 4 arranged in parallel at the edge of the load platform 1. The two fixing parts 4 are symmetrically arranged with respect to the diameter of the load platform 1, so that the forces on the two fixing parts 4 are balanced, thus making the installation more stable.

[0028] Furthermore, in this embodiment, as Figure 1As shown, the fixing part 4 comprises a mounting body 11 and a connecting rod 12 for fixing the load platform 1 to the inner gantry of the device to be tested, the connecting rod 12 extends the function of the load platform 1 to some extent, so that the load platform 1 can be located directly above the area to be tested, one end of the connecting rod 12 is connected with the edge of the load platform 1, and the other end is connected with the mounting body 11, and the connecting rod 12 can be a straight metal rod. Figure 1 As shown, the mounting body 11 can be in the form of a "U" structure, one end of which is connected with the connecting rod 12, and the other end is provided with a tension bolt, the "U" structure is clamped inside the inner gantry of the device to be tested, and the fixing part 4 is fixed to the inner gantry through the tension bolt.

[0029] In this embodiment, as shown in the figure, Figure 2 The hook 2 comprises a hook handle 5 and a hook body 6, the hook handle 5 is provided with a rope hole 7 and a hinge hole 8, when the hook 2 is installed on the load platform 1, the rope hole 7 is located above the load platform 1, and the hook body 6 is located below the load platform 1, the hook 2 is hinged together with the load platform 1 through a pin shaft 16 and the hinge hole 8; the load platform 1 is provided with a first recess 14, and a second recess 15 is provided perpendicularly to the first recess 14, when the load platform 1 is viewed from above, the first recess 14 and the second recess 15 form a "cross", the pin shaft 16 is arranged on the hook 2, and then the pin shaft 16 is arranged in the second recess 15, the hook 2 is arranged in the first recess 14, and the hook 2 can be installed on the load platform 1; the hook 2 is designed to have a certain included angle a between the hook handle 5 and the hook body 6, so as to form a whole curved shape, at this time, the curved part is provided with the hinge hole 8, and when the hook 2 is hinged on the load platform 1, the protruding position is directed to the center direction of the load platform 1, and the included angle a is shown in the figure, Figure 2 When the weight is hung on the hook body 6, the hook body 6 is in a vertical state, the vertical state here is that the center line of the hook body 6 is perpendicular, and the rope hole 7 on the hook handle 5 can extend to the outside of the load platform 1, at this time, when a person standing on the ground uses the unhooking rope 3 arranged on the rope hole 7, the pulling force of the unhooking rope 3 has a larger included angle a with the hook handle 5, so that the hook 2 is more easily stressed.

[0030] In this embodiment, as shown in the figure, Figure 1 The load platform 1 is provided with an opening 13, the opening 13 extends to the center position of the load platform 1, and the first hook 9 is hinged inside the opening 13 and at the center position of the load platform 1. The position of the opening 13 can be opposite to the position of the mounting part as shown in the figure. Figure 1 The test device of the present application is excellent and symmetrically arranged as a whole, so that when the fixing part 4 is installed on the inner gantry of the device to be tested, the load platform 1 is balanced in stress.

[0031] The following will describe the specific use mode of the test device provided in the embodiment, and the main steps are as follows:

[0032] (I) Before the test, the center point of the load platform 1 is placed above the driver (sitting or standing) and is fixed to the inner gantry beam through the other end of the mounting part, and the test height is adjusted through the lifting of the inner gantry;

[0033] (II) During the test, the standard impact block is hung on the hook 2, and the unhooking rope 3 is connected with the corresponding hook 2, and one impact test is completed by pulling the unhooking rope 3, when the hook 2 is rotated around the hinge position, at this time the weight hung on the hook body 6 will be free falling under the action of gravity and impact on the roof rack; the impact test of the remaining points is completed in turn by the above method, and the test results can be observed.

[0034] The above test device is used for detection in this embodiment, which avoids manual calculation of impact points (the position of the hook 2 is directly above the impact point), and does not need the assistance of other hoisting equipment, so that the positioning accuracy of the impact point is improved, the number of detection personnel is reduced, and the test time is greatly shortened.
