DETAILED DESCRIPTION

[0019] The present invention will be further explained below with reference to the accompanying drawings:

[0020] Reference Figure 1 The experimental object damping coupling body 17 is composed of an outer bushing 1, a damping material 2 and an inner bushing 3.

[0021] See also Figure 2-Figure 5 The upper platen 4 and lower seat 16 are both equipped with six universal wheels 15, each with a brake. The upper platen 4 and lower seat 16 are connected via a fixing assembly comprising multiple screws 18 located on the inner and outer rings of the damping coupling 17, along with corresponding fixing nuts 5. These nuts are tightened with spring washers 6 and flat washers 7 to seal and clamp the damping coupling 17 between the upper platen 4 and lower seat 16.

[0022] Two O-shaped sealing grooves are provided on the bottom surface of the upper pressure plate 4 at positions corresponding to the end faces of the inner and outer bushings 3 and 2 of the damping coupling body 17, and O-shaped sealing rings 11 are installed in the O-shaped sealing grooves. A through interface 19 is provided on the upper pressure plate 4 between the two O-shaped sealing grooves, and the interface is connected to the pressure gauge 10 and the hose 12 via a direct pipe joint 8 and a three-way pipe joint 9, and is equipped with a valve 13 and is connected to a pressure test pump 14.

[0023] The interface 19 has an internal thread, and the straight pipe connector 8 has an external thread that matches the internal thread, and the two are threadedly connected.

[0024] Strength test process:

[0025] like Figure 2 As shown, the upper pressure plate 4 and the lower seat plate 16 are transported to the strength test area via the universal wheels 15 and fixed with brakes. The position of the flange of the damping connector 17 is marked on the lower seat plate 16 with a marker pen, and the damping connector 17 is placed on the lower seat plate 16 using a crane and a lifting rope, with the flange end facing down and the non-flange end facing up.

[0026] Install two O-rings 11 into the O-shaped sealing groove of the upper pressing plate 4, as shown in the figure. Figure 5 shown.

[0027] like Figure 2 As shown, the upper pressure plate 4 equipped with the O-ring 11 is hoisted to the non-flange end of the damping coupling 17 by a crane and a hoisting rope, so that the two O-rings 11 contact the end faces of the inner and outer bushings 3 and 2 respectively.

[0028] like Figure 4 、 Figure 5 As shown, the straight pipe joint 8 is threadedly connected to the interface 19 of the upper pressure plate 4, the other end of the straight pipe joint 8 is connected to the three-way pipe joint 9, and the other two ends of the three-way pipe joint 9 are respectively connected to the pressure gauge 10 and the hose 12.

[0029] like Figure 2 As shown, a valve 13 is installed in the middle of the hose 12, and the end of the hose 12 is connected to the pressure test pump 14. The upper pressure plate 4 and the lower seat plate 16 are fixed by multiple screws 18, nuts 5, spring washers 6, and flat washers 7. After locking, the upper pressure plate 4 and the lower seat plate 16 clamp the damping coupling body 17, and a local sealed space is formed between the upper pressure plate 4 and the end face of the damping material 2 between the two O-rings 11.

[0030] like Figure 2As shown, open the valve 13, use the pressure test pump 14 to pressurize the water, and the water enters the above-mentioned sealed space through the hose 14 through the three-way pipe joint 9 and the straight pipe joint 8 through the interface 19 to achieve a pressure test on the damping material. Observe the value of the pressure gauge 10. When the value of the pressure gauge 10 reaches the required value for the strength test, close the valve 13, maintain the pressure for a certain period of time, and observe whether the value of the pressure gauge 10 changes. If there is no change, the casting damping quality of this damping connector 17 is qualified, otherwise it is unqualified.

[0031] After the strength test is completed, open valve 13 to release the pressure. When the value of pressure gauge 10 returns to zero, the pressure relief is completed. Remove the nut 5, spring washer 6, and flat washer 7 of the upper pressure plate 4, and use the crane and lifting rope to lift the damping coupling 17 away from the strength test device. Then, use the crane and lifting rope to lift the next damping coupling 17 to the lower seat plate 16, and repeat the previous steps.

[0032] The utility model provides a device for performing strength testing on the non-flange end face of a damping connector, which is easy to disassemble and assemble, has reliable performance and is reusable. The utility model improves the working efficiency of verifying whether the casting damping quality of the damping connector is qualified.
