[0028] The embodiments of the present invention will be described in detail below. The examples of the embodiments are shown in the drawings. The embodiments described below with reference to the drawings are exemplary and are intended to explain the present invention, and should not be construed as a limitation to the present invention.

[0029] Below with reference to Figures 1 to 4 ..., the test ball lifting and releasing assembly 100 and the drop ball test device 1000 of the embodiments of the present invention will be described in detail.

[0030] The drop ball test device 1000 of the embodiments of the present invention includes a bracket 200, a test ball lifting and releasing assembly 100, and a test ball 300.

[0031] The test ball lifting and releasing assembly 100 of the embodiments of the present invention includes a driver 1 and an electromagnetic suction member 2. The driver 1 is provided on the bracket 200. As Figure 4 shown, the driver 1 is provided at the upper end of the bracket 200. The driver 1 has a mobile end 11 that can move in a preset direction (for example Figure 1 and Figure 4 the up and down direction in...). The electromagnetic suction member 2 includes a body 21 and a wire (not shown in the figure). The body 21 is electrically connected to the wire. One end of the body 21 in this preset direction is connected to the mobile end 11 of the driver 1. The test ball 300 is detachably connected to the other end (lower end) of the body 21 in this preset direction. The other end of the body 21 is in contact connection with the test ball 300 when the wire is energized.

[0032] During the process of conducting a drop ball test using the drop ball test device 1000 according to an embodiment of the present utility model, when it is necessary to lift the test ball 300 to a high position, the driving member 1 is activated, causing the moving end 11 of the driving member 1 to move downward to a position adjacent to the test ball 300. Then, the driving member 1 is turned off, the wire of the electromagnetic suction member 2 is connected to a power source and turned on. After the main body 21 is energized, a magnetic suction force is generated, enabling the main body 21 to be attached to and connected to the test ball 300 by the magnetic suction force, so that the main body 21 and the test ball 300 are relatively fixed. During the process of the main body 21 magnetically attracting the test ball 300, personnel assist in adjusting the position of the main body 21 so that the other end of the main body 21 fits against the upper end surface of the test ball 300. Then, the driving member 1 is activated, causing the driving member 1 to drive the moving end 11 to lift, thereby driving the electromagnetic suction member 2 and the test ball 300 to lift. When the test ball 300 reaches the set position, the driving member 1 is turned off. When it is necessary for the test ball 300 to fall for testing, the power source connected to the wire is turned off, causing the main body 21 to lose power and the magnetic suction force to disappear. After the magnetic suction force disappears, the test ball 300 detaches from the main body 21 under the action of its gravity and falls.

[0033] It should be noted that the wire extends out of the main body 21 from one side in the horizontal direction of the main body 21 or from the upper side of the main body 21. The wire does not adhere to the bracket 200 and has a certain length, which can ensure the fixation of the end of the wire connected to the power source when the main body 21 moves up and down.

[0034] The test ball lifting and releasing assembly 100 according to an embodiment of the present utility model is detachably connected to the test ball 300 through the electromagnetic suction member 2. The magnetic suction force generated by the energization of the electromagnetic suction member 2 enables the main body 21 to stably connect to the test ball 300. After the electromagnetic suction member 2 is powered off, the magnetic suction force disappears, enabling the test ball 300 to detach from the main body 21, so that the moving end 11 of the driving member 1 can be detachably connected to the test ball 300 through the electromagnetic suction member 2. When it is necessary to lift the test ball 300, the electromagnetic suction member 2 is energized, and the driving member 1 drives the test ball 300 to lift, thereby reducing the labor intensity of personnel. Moreover, the driving member 1 drives the test ball 300 to rise, and the rising distance is controllable and easy to control, which can ensure the accuracy of the height of the test ball 300. When the test ball 300 needs to fall, the electromagnetic suction member 2 is powered off, and the test ball 300 detaches from the electromagnetic suction member 2 and falls. This makes the falling of the test ball 300 not only highly controllable, but also compared with the test ball connected with a rope in the related art, the falling of the test ball 300 is no longer affected by the rope, and personnel can also keep a certain distance from the bracket 200 to avoid potential risks and reduce safety hazards.

[0035] Therefore, the test ball lifting and releasing assembly 100 according to an embodiment of the present utility model has a simple operation process for lifting and releasing the test ball 300, reduces the degree of personnel participation, also reduces the labor intensity of personnel, improves the safety of the test, and also improves the test accuracy of the drop ball test device 1000.

[0036] In some embodiments, the driving member 1 is an electric hoist, which has a lifting rope 12, and the end of the lifting rope 12 forms a mobile end 11. The electric hoist is small in volume, light in self-weight, and simple to operate.

[0037] In some embodiments, the test ball lifting and releasing assembly 100 further includes a limit plate 3, which is arranged on the lifting rope 12 and is adjacent to the mobile end 11. During the process of the electric hoist driving the test ball 300 to rise, the lifting rope 12 is wound up, and the limit plate 3 moves upward with the end of the lifting rope 12. When the limit plate 3 abuts against the upper end of the bracket 200, the end of the lifting rope 12 can no longer be lifted, which also means that the test ball 300 is lifted to the set position, and then the electric hoist is turned off. Thus, the limit plate 3 has the function of limiting the movement of the lifting rope 12 and also has the function of prompting the lifting position of the test ball 300, so as to ensure that the test ball 300 reaches the set height and ensure the accuracy of the height position of the test ball 300.

[0038] In some embodiments, a hook 13 is provided at the mobile end 11 of the driving member 1. Specifically, the electric hoist has a hook 13, and the end of the lifting rope 12 is connected to the hook 13. The electromagnetic suction member 2 further includes a connecting ring 23, a connecting screw 24 and a nut 25. There are two connecting rings 23, and the two connecting rings 23 are arranged at intervals. The connecting screw 24 passes through the hook 13 and the connecting ring 23. The hook 13 is located between the two connecting rings 23. Nuts 25 are respectively fitted on both sides of the connecting screw 24 corresponding to the connecting ring 23, and the nuts 25 are in contact with the connecting ring 23.

[0039] When installing the hook 13 and the electromagnetic suction member 2, first pass the connecting screw 24 through the hook 13, and then screw on the nuts 25 from both ends of the connecting screw 24 respectively, that is, the two nuts 25 are respectively located on both sides of the hook 13. Then pass one end of the connecting screw 24 through one of the connecting rings 23, adjust the position of the connecting screw 24, pass the other end of the connecting screw 24 through the other connecting ring 23, and then screw on the nuts 25 from both ends of the connecting screw 24 respectively, and adjust the position of the nuts 25 so that both sides of the connecting ring 23 are in contact with the nuts 25, thereby fixing the positions of the connecting screw 24 and the connecting ring 23, blocking both sides of the connecting screw 24 in the hook 13, preventing the hook 13 from separating from the connecting screw 24, and ensuring the reliability of the connection between the mobile end 11 of the driving member 1 and the electromagnetic suction member 2.

[0040] In some embodiments, the body 21 is cylindrical.

[0041] In some embodiments, the two connecting rings 23 are symmetrically arranged with the axis of the body 21 as the center of symmetry. When the body 21 is lifted, it is beneficial to ensure the balance of the body 21 and avoid the situation of the body 21 tilting. Thus, it is also beneficial to ensure the balance of the test ball 300 when it is lifted and avoid the situation of the test ball 300 tilting. Subsequently, the stability of the lifting process of the test ball 300 is improved, and the reliability of the drop ball test device 1000 according to the embodiment of the present invention is improved.

[0042] In some embodiments, the hook 13 is located on the extension line of the axis of the body 21, and nuts 25 are attached to both sides of the hook 13. The hook 13 is fixed to the connecting screw 24 by the two nuts 25 to prevent relative movement between the hook 13 and the connecting screw 24, ensure that the hook 13 is located on the extension line of the axis of the body 21, and further avoid the situation of the body 21 tilting and the situation of the test ball 300 tilting. Subsequently, the stability of the lifting process of the test ball 300 is improved, and the reliability of the drop ball test device 1000 according to the embodiment of the present invention is further improved.

[0043] In some embodiments, the multiple nuts 25 between the hook 13 and the connecting ring 23 are sequentially attached, making it difficult for the nuts 25 between the hook 13 and the connecting ring 23 to move, and capable of preventing the slippage of the nuts 25. Thus, the relative fixation between the hook 13 and the connecting screw 24 is further ensured, and the stability and reliability of the connection between the hook 13 and the body 21 are guaranteed. Subsequently, the stability of the lifting process of the test ball 300 is further improved, and the reliability of the drop ball test device 1000 according to the embodiment of the present invention is further improved.

[0044] In some embodiments, the body 21 has an avoidance hole 211 that extends along a preset direction. As Figure 3 shown, the body 21 is annular. The avoidance hole 211 forms an avoidance space, which can provide space for the hanging ring or nut at the upper end of the test ball in the related art, enable the lower end surface of the body 21 to fit the upper end surface of the test ball 300, ensure the magnetic suction force of the body 21 on the test ball 300, and ensure the connection stability between the body 21 and the test ball 300. Subsequently, the stability of the lifting process of the test ball 300 is further improved, and the reliability of the drop ball test device 1000 according to the embodiment of the present invention is further improved.
