For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal connection of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present utility model can be understood according to specific circumstances. In addition, the technical features involved in the different embodiments of the present utility model described below can be combined with each other as long as they do not conflict with each other.

[0023] like Figures 1 to 4 As shown, the vibration test device 100 of the high-protection test piece of the utility model comprises a protective glove box 1, a test piece table 2 for placing the high-protection test piece and sealing the protective glove box 1, and a vibrator 3 for driving the test piece table 2 to vibrate.

[0024] The protective glove box 1 includes a box body 11 , protective gloves installed on the box body 11 , a material transfer channel 12 connected to the box body 11 , a fixing bracket 13 fixedly connecting the box body 11 and the ground, and a guide assembly 14 .

[0025] The box 11 is columnar. In this embodiment, the box 11 is a rectangular parallelepiped and has four side walls 112 and a top wall 111. A vibration opening is provided at the bottom for the specimen table 2 to enter. The material of the box 11 can be changed according to needs, such as using radiation-proof material or explosion-proof material.

[0026] The box body 11 is provided with a glass observation window 113. The glass observation window is arranged on a side wall 112, and is used to observe the test piece in the protective glove box 1, and is convenient for the installation of the test piece.

[0027] The material transfer channel 12 can be connected to other process operations or transfer materials, and has strong expandability. A seal is provided in the material transfer channel 12 to close the material transfer channel 12 after the test piece enters.

[0028] The number of the protective gloves is two, which are used for the staff to operate the test piece in the box 11 and also play a sealing role. Two glove holes 114 for installing the protective gloves are opened on one of the side walls 112.

[0029] The specimen table 2 is received in the vibration port and sealed with the protective glove box 1 , so that the internal specimen environment of the protective glove box 1 is separated from the external working environment, thereby preventing equipment from being contaminated and personnel from being harmed.

[0030] The vibrator 3 includes a vibrating base 31 fixed on the ground, a hydraulic actuator 32 arranged on the vibrating base 31, an adapter plate 33 arranged on the hydraulic actuator 32, and a servo valve 34 for controlling the operation of the hydraulic actuator 32. The adapter plate 33 is fixed to the specimen table 2. The vibrator 3 is used to drive the specimen table 2 to vibrate up and down. The servo valve 34 controls the hydraulic actuator 32 to move up and down, and connects to the clean surface of the specimen table 2, i.e., the lower end surface, through the adapter plate 33 installed on the piston rod of the hydraulic actuator 32, to achieve the function of driving the specimen table 2 to reciprocate vertically. The whole is in a clean environment, which is convenient for personnel to inspect and repair.

[0031] Although the specimen table 2 vibrates up and down, it can still be sealed with the protective glove box 1 at every position.

[0032] The guide assembly 14 is fixedly arranged in the protective glove box 1, and the test piece table 2 is provided with a guide column 21 passing through the guide assembly 14 in the vertical direction, and the guide assembly 14 limits the horizontal movement of the guide column 21. That is, the guide assembly 14 limits the guide column 21 and the test piece table 2 to vibrate only in the vertical direction, and will not move in the horizontal direction, so as not to affect the sealing effect.

[0033] There are four groups of guide posts 21 and guide components 14. The guide components 14 are respectively arranged on the four side walls 112 of the box body 11. The four groups of guide components 14 can improve the anti-overturning property of the specimen table 2 and fix the specimen table 2 while satisfying the vertical reciprocating motion.

[0034] The guide assembly 14 includes a mounting block 141 fixed on the side wall 112 of the protective glove box 1 and a linear bearing 142 fixed on the mounting block 141 . The guide column 21 passes through the linear bearing 142 in a vertical direction.

[0035] The linear bearing 142 includes a bearing portion 1421 for the guide column 21 to pass through and a fixing portion 1422 for fixing to the mounting block 141. The fixing portion 1422 is located at the upper end of the bearing portion 1421. The fixing portion 1422 is longer than the bearing portion 1421 in the horizontal direction. The fixing portion 1422 protrudes from the bearing portion 1421 and is fixed to the mounting block 141 by bolts.

[0036] The guide column 21 includes a column 211 and a limiting portion 212. The column 211 is cylindrical and has a lower end fixed to the specimen table 2. The limiting portion 212 is fixed to the column 211 and has a horizontal length greater than the diameter of the column 211 so as to be clamped with the guide assembly 14 in the vertical direction.

[0037] When the limiting portion 212 is clamped with the guide assembly 14, the test piece table 2 is sealed against the protective glove box 1. In this embodiment, when the limiting portion 212 is clamped with the guide assembly 14, the upper end surface of the test piece table 2 is higher than the lower end surface of the protective glove box 1.

[0038] The guide column 21 not only guides the test piece table 2 and improves the anti-overturning property of the test, but also sets a lower limit for the test piece table 2 to prevent the test piece table 2 from falling when the vibrator 3 is not connected.

[0039] The vibration test device 100 for high-protection test pieces of the utility model can meet the requirements of vertical vibration excitation tests for highly polluting and dangerous test pieces and is not easily polluted. By providing the guide column 21 and the guide assembly 14, the test is guided and the anti-overturning property of the test is improved.

[0040] The technical features of the above-described embodiments may be arbitrarily combined. To make the description concise, not all possible combinations of the technical features in the above-described embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0041] The above-mentioned embodiments only express several implementation methods of the utility model, and the description is relatively specific and detailed, but it cannot be understood as limiting the scope of the utility model patent. It should be pointed out that for ordinary technicians in this field, several modifications and improvements can be made without departing from the concept of the utility model, which all belong to the protection scope of the utility model. Therefore, the protection scope of the utility model patent shall be based on the attached claims.
