[0030] The embodiments of the present invention are described in detail below, and examples of the embodiments are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to be used to explain the present invention, but cannot be understood as limiting the present invention.

[0031] like Figures 1 to 7 As shown, the falling ball test device 100 of the embodiment of the utility model comprises a fixing seat 1, a frame 2, a test ball 4 and a connecting rope 5. The fixing seat 1 is used to fix the sample 200. The frame 2 surrounds the fixing seat 1, and the fixing seat 1 is located on the frame 2 in a first direction (for example Figure 1 The frame 2 is spaced apart from the fixing seat 1. The test ball 4 is opposite to the fixing seat 1 in the first direction, and the test ball 4 is connected to one end of the connecting rope 5, and the other end of the connecting rope 5 is passed around the other end of the frame 2 in the first direction.

[0032] When the falling ball test device 100 of the embodiment of the utility model is in use, the first direction is the same as the up-down direction, and the other end of the frame 2 is the upper end of the frame 2, the one end of the frame 2 is the lower end of the frame 2, and the lower end of the frame 2 and the fixing seat 1 are both fixed on the support platform. The connecting rope 5 lifts the test ball 4 so that the test ball 4 is located at the upper end of the frame 2, and the test sample 200 is installed on the fixing seat 1, and then the fixing of the connecting rope 5 is loosened to release the test ball 4, and the test ball 4 falls onto the sample 200 under the action of its gravity.

[0033] It should be noted that the support platform is the platform on which the falling ball test device 100 is located. For example, if the falling ball test device 100 is located on the ground, the support platform is the ground.

[0034] The frame 2 of the drop ball test device 100 of the embodiment of the utility model surrounds the fixed seat 1, and the fixed seat 1 is located on the inner side of the frame 2, and the test ball 4 is opposite to the fixed seat 1 in the up and down direction, so the test ball 4 is located on the inner side of the frame 2, and the frame 2 provides stable support for the test ball 4. The fixed seat 1 and the frame 2 of the installation sample 200 are spaced apart, and the fixed seat 1 and the frame 2 are not connected. The fixed seat 1 and the frame 2 are non-integrated structures, so that after the test ball 4 is released, when the drop ball impact test is performed, when the test ball 4 hits the fixed seat 1, the impact energy will not be directly transferred from the fixed seat 1 to the frame 2, thereby avoiding the shaking of the frame 2 with a certain height, ensuring the stability of the frame 2 during the test process, and thus improving the test safety of the drop ball test device 100.

[0035] Furthermore, the fixing seat 1 and the frame 2 are separately provided, and their respective manufacture and maintenance can be carried out separately, thereby reducing the cost of manufacture and maintenance, and reducing the difficulty and complexity of maintenance.

[0036] In some embodiments, Figure 1 As shown, the frame 2 includes a support frame 21, a hanging frame 22, a connecting rod 23 and a fixing plate 24. The support frame 21 and the hanging frame 22 are respectively located at one end and the other end of the frame 2. The connecting rod 23 extends along the first direction. The two ends of the connecting rod 23 are respectively connected to the support frame 21 and the hanging frame 22. The fixing seat 1 is located in the support frame 21. A plurality of fixing plates 24 are provided on the outer side of the support frame 21. The fixing plates 24 are used to connect with the supporting platform. The support frame 21 and the fixing plates 24 of the frame 2 are both in contact with the supporting platform. The support frame 21 and the fixing plates 24 are the bottom surfaces of the frame 2 in contact with the supporting platform. The support frame 21 and the fixing plates 24 form a larger supporting surface of the frame 2, ensuring the stability of the frame 2. In addition, the structure of the frame 2 is simple, easy to manufacture, and low in cost.

[0037] Specifically, the support frame 21 is a rectangular frame, the hanging frame 22 is a rectangular frame, and the frame 2 is welded with aluminum profiles. The frame 2 is a symmetrical frame, such as Figure 1 and Figure 2 As shown, the frame 2 is symmetrical front to back and left to right.

[0038] In some embodiments, the drop ball test device 100 further includes two guide rods 6, one end (upper end) of the guide rod 6 is disposed on the hanging frame 22, the guide rod 6 extends along the first direction, the other end (lower end) of the guide rod 6 is spaced from the fixing seat 1, and the two guide rods 6 are located on both sides of the test ball 4 and are symmetrically arranged. The symmetry center of the two guide rods 6 is the same as the symmetry center of the frame 2. The two guide rods 6 guide the falling of the test ball 4, ensuring that the test ball 4 falls onto the sample 200 on the mounting seat in the up and down directions, preventing the test ball 4 from deviating from the preset position, ensuring the effectiveness of the test process, and further improving the test safety of the drop ball test device 100.

[0039] In some embodiments, Figure 2 As shown, the outer contour of the cross section of the guide rod 6 is L-shaped and has a folded angle, the folded angles of the two guide rods 6 are arranged back to back, the test ball 4 is located on the acute angle side of the folded angle of the guide rod 6, and the two guide rods 6 surround the test ball 4, so that the two guide rods 6 limit the test ball 4 in the front and rear directions and the left and right directions, thereby further improving the guiding effect of the two guide rods 6 on the test ball 4, further preventing the test ball 4 from hitting other places during the drop ball impact test, further ensuring that the test ball 4 falls onto the sample 200 of the mounting seat, and further improving the test safety of the drop ball test device 100.

[0040] The ball drop test device 100 in this embodiment further includes a first fixed pulley 7 and a second fixed pulley 8, the first fixed pulley 7 is arranged on the hanging frame 22, the first fixed pulley 7 and the test ball 4 are opposite in the first direction, the second fixed pulley 8 is arranged at the edge of the hanging frame 22, and the connecting rope 5 passes around the first fixed pulley 7 and the second fixed pulley 8. The first fixed pulley 7 and the second fixed pulley 8 guide the connecting rope 5 to avoid friction between the connecting rope 5 and the frame 2, thereby ensuring the service life of the connecting rope 5.

[0041] In some embodiments, the test ball 4 includes a hanging ring 41, a fixed plate 42, a ball head 43, a counterweight plate 44 and a locking nut 45. The hanging ring 41 includes a ring portion 411 and a suspension rod portion 412. The ring portion 411 is connected to the one end of the connecting rope 5, and the suspension rod portion 412 is connected to the ring portion 411. The suspension rod portion 412 is provided with an external thread. One end (upper end) of the fixed plate 42 in the first direction is threadedly connected to the suspension rod portion 412. The ball head 43 is detachably provided on the other end (lower end) of the fixed plate 42 in the first direction. The counterweight plate 44 is sleeved on the suspension rod portion 412. The counterweight plate 44 is located between the ring portion 411 and the fixed plate 42. The locking nut 45 is fitted on the suspension rod portion 412. The locking nut 45 is located between the counterweight plate 44 and the ring portion 411, and the locking nut 45 abuts against the fixed plate 42.

[0042] When assembling the test ball 4, the locking nut 45, the weight plate 44 and the fixed plate 42 are successively sleeved on the suspension rod portion 412, and the locking nut 45 is tightened in the direction close to the weight plate 44 to complete the fixation of the locking nut 45, the weight plate 44, the fixed plate 42 and the suspension rod, and the ball head 43 is fixed to the fixed plate 42 to complete the assembly of the test ball 4. Therefore, the weight of the test ball 4 can be adjusted by replacing the number and weight of the weight plates 44, and the ball head 43 of the test ball 4 is also easy to replace, so that the test ball 4 can adapt to different test requirements, improve the application flexibility of the test ball 4, and also improve the adaptability and flexibility of the falling ball test device 100 of the embodiment of the utility model.

[0043] Specifically, a threaded blind hole is provided on the end of the fixing plate 42, and the threaded blind hole is threadedly connected to the suspension rod. When the fixing plate 42 and the suspension rod are assembled, when the fixing plate 42 is tightened until it cannot be twisted, it means that the fixing plate 42 is completely assembled to the suspension rod portion 412. The fixing plate 42 is equivalent to forming a limit on the lower side of the counterweight plate 44, and the locking nut 45 forms a limit on the upper side of the counterweight plate 44, so as to fix the counterweight plate 44 and the suspension rod portion 412, and at the same time, it is convenient to disassemble the counterweight plate 44 and adjust the weight of the test ball 4.

[0044] In some embodiments, the ball head 43 includes a connected head 431 and a fixing portion 432, the fixing portion 432 is provided with a connecting hole, and the other end of the fixing plate 42 is provided with a threaded hole. The test ball 4 further includes a screw 433, the screw 433 passes through the connecting hole and fits in the threaded hole, and the screw 433 connects the fixing plate 42 and the fixing portion 432, thereby connecting the fixing plate 42 and the ball head 43.

[0045] When the test ball 4 falls onto the sample 200, the head 431 of the ball head 43 first contacts the sample 200. Different ball heads 43 have different shapes of head 431, so they can adapt to different testing requirements. The connection between the fixing portion 432 of the ball head 43 and the fixing plate 42 is simple and firm, so that the test ball 4 can be easily replaced with heads 431 of different shapes, thereby improving the application flexibility of the test ball 4 and also improving the adaptability and flexibility of the falling ball test device of the embodiment of the utility model.

[0046] In some embodiments, the falling ball test device 100 further includes a hoisting assembly 3, which includes a fixed frame 31, a reel 32 and a rocker 33.

The rocker 33 is turned to drive the reel 32 to rotate, so that the connecting rope 5 is wound around the reel 32, so that the test ball 4 located at a low place, such as on a support platform or on the sample 200, is gradually raised and hoisted to the upper end of the frame 2. When a test is required, the rocker 33 is released, the connecting rope 5 is loosened, and the test ball 4 falls onto the sample 200.

[0047] In some embodiments, the fixing base 1 includes a base 11, a support frame 12 and a support plate 13. The base 11 has a mounting platform 111 on one side of the first direction. The base 11 is spaced apart from the frame 2. The support frame 12 has two support frames 12.

The third direction is orthogonal to the first direction and the second direction. The support plates 13 and the support frame 12 are used to install the sample 200.

[0048] The fixing seat 1 uses the support plate 13 and the support frame 12 as the fulcrum for installing and fixing the sample 200. The two support plates 13 and the two support frames 12 are arranged to form a quadrilateral to support the four sides of the sample 200. For the installation of samples 200 of different sizes, according to the size of the installed sample 200, the positions of the two support frames 12 on the installation platform 111 are adjusted, the distance between the two support frames 12 in the second direction is adjusted, and the distance between the two support plates 13 in the third direction is adjusted, so as to ensure that the quadrilateral formed by the two support frames 12 and the two support plates 13 corresponds to the size of the sample 200, so as to support and install the sample 200, thereby realizing the fixing of the sample 200 by the fixing seat 1.

[0049] The fixed seat 1 of the embodiment of the utility model supports and fixes the sample 200 through the support frame 12 and the support plate 13.
