Description

Technical Field

[0001] The invention belongs to the technical field of rail transportation, and in particular relates to an impact vibration test device for side window glass of a rail vehicle. Background Art

[0002] Rail transit refers to a type of transportation vehicle or transportation system in which operating vehicles need to travel on specific tracks. Rail transit is one of the most important transportation vehicles among existing transportation vehicles. Due to the complexity of the track operating environment, in order to ensure the operating quality of the vehicle's upper side window glass, impact and vibration tests should be conducted to simulate its operating environment conditions before installation.

[0003] Since rail transit generates a lot of noise, the side window glass of the vehicle is generally thicker and heavier soundproof glass. When using existing test equipment, the glass is directly lifted to the placement position on the test equipment by a lifting device, and then the connection between the lifting device and the glass is released. The glass is subsequently fixed by other fixing equipment. After the connection between the lifting device and the glass is released and before it is fixed, the glass is in a free state. In order to simulate the actual vehicle operating environment, the test glass is in a vertical state, so its placement stability is poor. Vibrations from external equipment will cause the glass to shake or even fall, increasing the risk during the test. In addition, when placing the glass by the lifting device, the position of the glass needs to be adjusted multiple times to align with the installation position of the glass, which makes it difficult to place it quickly and accurately, reducing the efficiency of the test. Summary of the Invention

The lifting mechanism is a bottom end of the lifting mechanism, and the lifting mechanism is a bottom end of the lifting mechanism.

[0006] Further technical solution: A support plate is slidably installed on the side of the pressure plate close to the mounting plate, and multiple groups of L-shaped limit plates are fixedly installed on the support plate. The limit plates are in sliding contact with the outer side surfaces of the pressure plate. A card slot for use with the limit plates is opened inside the lower side wall of the positioning frame, and an adjusting screw is rotatably installed on the pressure plate to drive the support plate to move.

[0007] Further technical solution: a lifting frame is slidably installed on the base, a fourth telescopic part is fixedly installed on the horizontal section of the lifting frame, a second connecting box is provided at the output end of the fourth telescopic part, and multiple groups of second suction cups are fixedly installed on the surface of the second connecting box close to the base. The second connecting box is connected to the main body of the negative pressure adsorption equipment, and a servo module for driving the lifting frame to move is provided on the base.

[0008] Further technical solution: A U-shaped slide is fixedly installed on the second connecting box, the slide is slidingly connected to the output end of the fourth telescopic member, the output end of the fourth telescopic member is fixedly installed with an electromagnet, the electromagnet is in sliding contact with the slide and the slide is made of magnetic material.

[0009] Further technical solution: A first guide frame is fixedly installed on the base, and a support seat with a U-shaped cross-section is slidably installed on the horizontal section of the first guide frame. Multiple groups of parallel distributed second rollers are rotatably installed in the support seat, and multiple groups of first rollers are rotatably installed at the bottom of the support seat. The first rollers are in rolling contact with the base and are used to support the weight of the support seat.

[0010] Further technical solution: An elastic member is fixedly installed on the side of the support seat, and the elastic member is distributed along the moving direction of the support seat. One end of the elastic member away from the support seat is fixedly connected to a pressure sensor fixedly installed on the first guide frame.

[0011] Further technical solution: a second guide frame is fixedly installed on the base, an L-shaped positioning frame is slidably installed on the second guide frame, one set of side walls of the positioning frame is parallel to the second roller, and multiple sets of spaced positioning rollers are rotatably installed inside the two sets of side walls of the positioning frame, and a third telescopic part that drives the positioning frame to move is fixedly installed on the second guide frame.

[0012] Further technical solution: A connecting rod is fixedly installed on the side wall of the positioning frame, and the connecting rod is used in conjunction with a connecting plate fixedly installed on the second connecting box.

[0013] Compared with the prior art, the present invention has the following beneficial effects: 1. Make the pressing plate horizontal, place the glass on the pressing plate so that the four sides of the glass are aligned with the four sides of the pressing plate, and use the negative pressure adsorption equipment body to make the first suction cup adsorb the glass to prevent the glass from moving at will. After the glass is fixed, the rotating power part drives the rotating frame to rotate in the opposite direction to rotate the rotating frame to a vertical state. Then the first telescopic part drives the pressing plate to move to the side of the vertical plate through the mobile frame, so that the glass enters the positioning frame and contacts the vertical plate. The glass is pressed against the vertical plate by the pressing plate to complete the fixation. The glass is placed, transported and subsequently pressed and fixed by the pressing plate, so that the glass remains stable throughout the process, and avoids secondary fixation after the glass enters the positioning frame, realizes integrated loading and fixing, avoids shaking of the glass, ensures the stability of the glass, reduces the influence of the external environment on the glass installation, and avoids multiple adjustments to the glass position, realizes rapid installation of the glass, and improves the efficiency of the test.

[0014] 2. Place the glass to be tested on the second roller, push the glass to move so that the front side of its moving direction contacts the positioning roller on the positioning frame. At this time, one side of the glass is parallel to one side of the positioning frame. Then the third telescopic member drives the positioning frame to move horizontally until the other side contacts the glass. The positioning of the glass can be completed through the positioning frame. Since the position of the pressure plate is fixed when it is horizontal, the positioning frame has completed the positioning of the glass, and the second connecting box moves synchronously with the positioning frame, so that in the subsequent use of the glass, the position of the second suction cup in contact with the glass is accurately fixed, and then the glass can be accurately transferred to the pressure plate, ensuring the accuracy of the position of the glass and the pressure plate, and ensuring that the subsequent glass can accurately enter the positioning frame.

[0015] 3. When the third telescopic member pushes the positioning frame to move so that the other side wall of the positioning frame contacts the side wall of the glass, the positioning frame will generate a thrust on the glass. Since the glass is heavy and the static friction between it and the second roller is large, the friction between the first roller and the base is small. Therefore, when the positioning frame generates a thrust on the glass, the support seat will move. When the support seat moves, it will compress the elastic member and cause the pressure sensor to generate a reading. After the pressure sensor generates a reading, it feeds back to the control center, and then stops extending the third telescopic member, realizing the detection of the contact between the side of the limit frame and the side of the glass, ensuring that the limit frame can accurately position the glass, and further improving the accuracy of subsequent glass placement.

DETAILED DESCRIPTION

[0023] In order to make the purpose, technical solutions and advantages of the present invention more clearly understood, the present invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0024] The specific implementation of the present invention is described in detail below with reference to specific embodiments.

[0025] like Figures 1-6 As shown, a rail vehicle side window glass impact vibration test device provided by the present invention includes a base 1, a vertical plate 2 is fixedly mounted on the base 1, a positioning frame 4 is fixedly mounted on one side surface of the vertical plate 2, a through slot 3 is formed on the vertical plate 2 and is located within the positioning frame 4, and vibrators 6 are fixedly mounted on two adjacent side edges of the base 1, the vertical plate 2, and the positioning frame 4; A mounting plate 7 is fixedly mounted on the vertical plate 2, a rotating frame 8 is rotatably mounted on the mounting plate 7, and a rotating power member 9 for driving the rotating frame 8 to rotate is fixedly mounted on the mounting plate 7, a mobile frame 10 is slidably mounted on the rotating frame 8, the mobile frame 10 passes through the rotating frame 8, and a pressure plate 11 of a frame-type structure that matches the positioning frame 4 is fixedly mounted on the end of the mobile frame 10, a first telescopic member 12 that drives the pressure plate 11 to move is fixedly mounted on the rotating frame 8, when the rotating frame 8 is parallel to the vertical plate 2, the pressure plate 11 is aligned with the positioning frame 4, a second telescopic member 13 is fixedly mounted on the mobile frame 10, and the second telescopic member 13 is fixedly mounted on the mobile frame 10. A first connecting box 14 is fixedly installed on the output end of the component 13, and multiple groups of first suction cups 15 are fixedly installed on the first connecting box 14. The first connecting box 14 is connected to the negative pressure adsorption device body 16 fixedly installed on the base 1. A support plate 17 is slidably installed on the side of the pressure plate 11 close to the mounting plate 7. Multiple groups of L-shaped limit plates 18 are fixedly installed on the support plate 17. The limit plates 18 are in sliding contact with the outer side surfaces of the pressure plate 11. A card slot 5 for cooperating with the limit plates 18 is opened inside the lower side wall of the positioning frame 4, and an adjusting screw 19 for driving the support plate 17 to move is rotatably installed on the pressure plate 11.

[0026] In actual application of this embodiment, the adjusting screw 19 is rotated according to the thickness of the glass to be tested to drive the support plate 17 to move, so that the set length of the limit plate 18 extends out of the pressure plate 11, and the rotating frame 8 is rotated by the rotating power member 9 to make the pressure plate 11 in a horizontal state, and the glass is placed on the pressure plate 11 so that the four sides of the glass are aligned with the four sides of the pressure plate 11. At this time, one side of the glass is in contact with the limit plate 18, and the height of the end of the limit plate 18 is lower than the height of the upper surface of the glass. After the glass is placed, the second telescopic member 13 drives the first suction cup 15 to move upward so that the first suction cup 15 is in contact with the lower surface of the glass, and then the first suction cup 15 is sucked by the negative pressure adsorption device body 16. Attach the glass to prevent it from moving at will. After the glass is fixed, the rotating power member 9 drives the rotating frame 8 to rotate in the opposite direction so that the rotating frame 8 rotates to a vertical state. At this time, the glass is in a vertical state and aligned with the positioning frame 4. Then, the first telescopic member 12 drives the pressing plate 11 to move toward the side of the vertical plate 2 through the moving frame 10, so that the glass enters the positioning frame 4 and contacts the vertical plate 2. The glass is pressed against the vertical plate 2 by the pressing plate 11 to complete the fixation. After that, the first suction cup 15 no longer absorbs the glass and the second telescopic member 13 contracts to make the first suction cup 15 away from the glass to avoid affecting the subsequent test of the glass. After that, the glass can be subjected to impact vibration test through the vibrator 6 at different positions. During the rotation of the glass, its lower part is supported by the limit plate 18, which ensures the stability of the glass during the loading and installation process, prevents the glass from falling during the rotation of the rotating frame 8, and improves the stability of the equipment. The glass is placed, transported and subsequently pressed and fixed by the pressure plate 11, so that the glass remains stable during the whole process, and avoids secondary fixation after the glass enters the positioning frame 4, realizes the integration of loading and fixing, avoids the shaking of the glass, ensures the stability of the glass, reduces the influence of the external environment on the installation of the glass, avoids multiple adjustments to the glass position, realizes the rapid installation of the glass, and improves the efficiency of the test. After the test is completed, the first suction cup 15 adsorbs the glass again, and then the first telescopic member 12 contracts to make the glass withdraw from the positioning frame 4, and then the rotating frame 8 rotates to a horizontal state and releases the fixation of the glass to remove the glass.

[0027] In an example of this embodiment, the rotating power part 9 is a motor, and of course it can also be other parts that can output rotational power, such as a hydraulic motor. The motor drives the rotating frame 8 to rotate to realize the movement of the glass. The first telescopic part 12 and the second telescopic part 13 are the first and second electric telescopic rods respectively. Of course, they can also be other parts that can actively change the length, such as a hydraulic cylinder. The first electric telescopic rod drives the pressure plate 11 to move, and the second electric telescopic rod drives the first suction cup 15 to move.

[0028] like Figures 1-6 As shown, a rail vehicle side window glass impact vibration test device provided by the present invention, a lifting frame 31 is slidably installed on the base 1, a fourth telescopic member 33 is fixedly installed on the horizontal section of the lifting frame 31, a second connecting box 35 is provided at the output end of the fourth telescopic member 33, a plurality of groups of second suction cups 36 are fixedly installed on the surface of the second connecting box 35 close to the base 1, the second connecting box 35 is connected to the negative pressure adsorption device body 16, and a servo module 32 for driving the lifting frame 31 to move is provided on the base 1.

[0029] Specifically, a U-shaped slide 34 is fixedly installed on the second connecting box 35, and the slide 34 is slidingly connected to the output end of the fourth telescopic member 33. An electromagnet 37 is fixedly installed on the output end of the fourth telescopic member 33, and the electromagnet 37 is in sliding contact with the slide 34, and the slide 34 is made of magnetic material.

[0030] Specifically, a first guide frame 22 is fixedly installed on the base 1, and a support base 20 with a U-shaped cross-section is slidably installed on the horizontal section of the first guide frame 22. Multiple groups of parallel distributed second rollers 23 are rotatably installed in the support base 20, and multiple groups of first rollers 21 are rotatably installed at the bottom of the support base 20. The first rollers 21 are in rolling contact with the base 1 and are used to support the weight of the support base 20.

[0031] Specifically, an elastic member 25 is fixedly installed on the side of the support base 20 , and the elastic member 25 is distributed along the moving direction of the support base 20 . One end of the elastic member 25 away from the support base 20 is fixedly connected to a pressure sensor 24 fixedly installed on the first guide frame 22 .

[0032] Specifically, a second guide frame 26 is fixedly installed on the base 1, and an L-shaped positioning frame 27 is slidably installed on the second guide frame 26. One set of side walls of the positioning frame 27 is parallel to the second roller 23. Multiple sets of spaced positioning rollers 28 are rotatably installed inside the two sets of side walls of the positioning frame 27. A third telescopic member 29 that drives the positioning frame 27 to move is fixedly installed on the second guide frame 26.

[0033] Specifically, a connecting rod 30 is fixedly mounted on the side wall of the positioning frame 27 , and the connecting rod 30 is used in conjunction with a connecting plate 38 fixedly mounted on the second connecting box 35 .

[0034] When the second connecting box 35 is moved to the set position, the fourth telescopic member 33 moves downward, so that the second suction cup 36 contacts the glass, and the second suction cup 36 adsorbs and fixes the glass through the negative pressure adsorption device body 16. Then the fourth telescopic member 33 retracts and moves upward to make the glass separate from the second roller 23 and the connecting rod 30 is still connected to the connecting plate 38. The third telescopic member 29 retracts to make the positioning The frame 27 and the second connecting box 35 are reset. After the reset, the electromagnet 37 is energized to attract the sliding plate 34 to complete the fixation of the second connecting box 35. Then the fourth telescopic member 33 contracts again to drive the glass to rise to the set height. At this time, the connecting rod 30 is disengaged from the connecting plate 38, and the servo module 32 drives the lifting frame 31 to move toward the side of the vertical plate 2 until the glass moves to the top of the pressing plate 11. Then the fourth telescopic member 33 is extended to move the glass downward and place it on the pressing plate 11. Then the second suction cup 36 is released to fix the glass and the lifting frame 31 and the second connecting box 35 return to the initial state. At the same time, the electromagnet 37 is de-energized. Since the pressing plate 11 is in a horizontal state and its position is fixed, the positioning frame 27 has completed the positioning of the glass, and the second connecting box 35 moves synchronously with the positioning frame 27. Therefore, in the subsequent use of the glass, the position of the second suction cup 36 in contact with the glass is accurately fixed, and then the glass can be accurately transferred to the pressing plate 11, ensuring the accuracy of the position of the glass and the pressing plate 11, and ensuring that the subsequent glass can accurately enter the positioning frame 4. When the third telescopic member 29 pushes the positioning frame 27 to move so that the other side wall of the positioning frame 27 contacts the side wall of the glass, the positioning frame 27 will generate a thrust on the glass. Since the glass is heavier and the static friction between it and the second roller 23 is larger, the friction between the first roller 21 and the base 1 is smaller. Therefore, when the positioning frame 27 generates a thrust on the glass, the support seat 20 will move. When the support seat 20 moves, it will compress the elastic member 25 and cause the pressure sensor 24 to generate a reading. After the pressure sensor 24 generates a reading, it feeds back to the control center. At this time, the extension of the third telescopic member 29 is stopped, and the detection of the contact between the side of the positioning frame 27 and the side of the glass is realized, ensuring that the positioning frame 27 can accurately position the glass, further improving the accuracy of subsequent glass placement.

[0035] In one embodiment of the present invention, the third telescopic member 29 and the fourth telescopic member 33 are respectively the third electric telescopic rod and the fourth electric telescopic rod, and of course they can also be other components that can actively change the length, such as a hydraulic cylinder. The positioning frame 27 is driven to move by the third electric telescopic rod, and the second connecting box 35 is driven to move by the fourth electric telescopic rod. The elastic member 25 is a spring, and of course it can also be other elastic components such as an elastic ball, and pressure is applied to the pressure sensor 24 through spring compression.

[0036] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.

[0037] In addition, it should be understood that although this specification is described in terms of implementation methods, not every implementation method contains only one independent technical solution. This narrative method of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment can also be appropriately combined to form other implementation methods that can be understood by those skilled in the art.
