Detailed Implementation

[0022] To enable those skilled in the art to better understand this utility model, the technical solution of this utility model will be further described below in conjunction with the accompanying drawings and embodiments.

[0023] Example 1: As Figures 1-4 As shown, this utility model discloses a stress testing device for building exterior curtain wall glass, comprising a main housing, a sliding slider 15 slidably mounted on the main housing, a pneumatic telescopic rod 16 mounted at the lower end of the sliding slider 15, an air guide pipe 14 connected to the pneumatic telescopic rod 16, a mounting frame 17 mounted at the output end of the pneumatic telescopic rod 16, and an optical stress detector 18 mounted at the lower end of the mounting frame 17.

[0024] The main box body comprises two support columns 20 and a placing table 21, T-shaped plates 22 in sliding connection with the support columns 20 are fixedly connected to the left and right sides of the mounting frame 17, a placing groove is formed in the inside of the placing table 21, a plurality of first springs 23 are installed in the inside of the placing groove, a placing plate 24 in fixed connection with the plurality of first springs 23 is in sliding connection with the inside of the placing groove, one of the T-shaped plates 22 is in sliding connection with a vertical shaft 25, a limiting plate 26 is fixedly connected to the lower end of the vertical shaft 25, a second spring 27 is installed between the limiting plate 26 and the T-shaped plate 22, a through hole in communication with the placing groove is formed in the placing table 21, a plurality of suction cups 28 are installed in the inside of the placing groove, and the plurality of suction cups 25 are in communication with a suction assembly.

[0025] According to the prior art CN202222656024.5, the technical content displayed in the microcrystalline glass finished product stress testing device drives the moving slider 15 to move left and right, at this time the air guide pipe 14 starts to extract gas, and then drives the pneumatic telescopic rod 16 to start moving up and down, at this time reaching the upper side of the curtain wall glass, and then the optical stress detector 18 touches the glass, and then detects the stress of the glass. The above is the technical content of the existing patent, which will not be repeated here. The utility model improves the placing table 21 on the basis of the above technology to improve the stability of the glass detection.

[0026] The rebound force of the second spring 27 is greater than that of the first spring 23, and when the second spring 27 and the first spring 23 interact, the first spring 23 is compressed first. When the telescopic rod 16 is started to move downward, the mounting frame 17 and the T-shaped plate 22 will move downward, so that the limiting plate 26 extends into the through hole and abuts against the placing plate 24. When the telescopic rod 16 is started to continuously move the T-shaped plate 22 downward, the downward force of the limiting plate 26 and the second spring 27 will make the placing plate 24 overcome the rebound force of the first spring 23 and move downward to release the suction cups 28. The stroke of the downward movement of the placing plate 24 matches the state after the suction cups 28 are adsorbed. After the placing plate 24 moves downward, the curtain wall glass will act on the upper ends of the plurality of suction cups 28. At this time, the suction assembly is started to suck, so that the suction cups 28 and the curtain wall glass are adsorbed together to fix and limit the curtain wall glass. In this way, the pneumatic telescopic rod 16 drives the optical stress detector 18 close to the curtain wall glass to detect the glass, and after the curtain wall glass is fixed, the optical stress detector 18 can accurately detect the stress of the glass at different positions. After the detection is completed, the suction assembly is used to exhaust to contact the adsorption of the suction cups 28 and the curtain wall glass, and then the pneumatic telescopic rod 16 is retracted to restore the initial state.

[0027] The utility model discloses a detection process is driven to the placement board to move down and leak the sucking disc by the downward movement of the mounting bracket and the T-shaped plate in the prior art, and the sucking disc is adsorbed to the curtain wall glass and is in abutment with the placement board through the air suction component, so that the curtain wall glass can be positioned and fixed, sliding of the curtain wall glass in the detection is avoided, and meanwhile the accuracy of the detection point of the optical stress monitor is improved.

[0028] In the further improvement based on example 1, the air suction component includes an air suction cylinder 30, the piston 31 is sealingly and slidably connected in the air suction cylinder 30, the elastic member is installed on the upper end of the piston 31, the abutment frame 32 is drivingly connected with the elastic member, the limiting member is slidably connected with the abutment frame 32, and the plurality of sucking discs 28 and the placement table 21 are provided with the air duct 35 which is in communication with the air suction cylinder 30.

[0029] When the T-shaped plate 22 moves downward, the placement board 24 is preferentially driven to move downward, and then the other T-shaped plate 22 is driven to move downward and abut against the abutment frame 32 to drive the abutment frame and the piston 31 to move downward, so that the piston 31 moves upward against the elastic force of the elastic member, and the air in the air duct 35 is sucked into the air suction cylinder 30 by the upward movement of the piston 31, and then the sucking disc 28 is sucked through the air duct 35 to be adsorbed with the curtain wall glass.

[0030] The elastic member includes a third spring 33 which is installed between the air suction cylinder 30 and the piston 31, the pull rope 34 which is fixedly connected with the upper end of the piston 31 and penetrates through the air suction cylinder 30 and is fixedly connected with the upper end of the abutment frame 32, and the T-shaped plate 22 is provided with the groove which is matched with the abutment frame 32.

[0031] In the initial state, the elastic force of the third spring 33 makes the piston 31 abut against the lower side of the air suction cylinder 30, and then the abutment frame 32 is pulled to be located on the upper side of the air suction cylinder 30 through the pull rope 34, so that when the abutment frame 32 moves downward under the force, the piston 31 is pulled to move upward through the pull rope 34, and then the elastic force of the third spring 33 is overcome, the upward movement of the sealingly and slidably connected piston 31 can make the air on the upper side of the air suction cylinder 30 be discharged, and the air sucked from the air duct 35 enters the lower part of the air suction cylinder 30, and then the sucking disc 28 is sucked.

[0032] The limiting member includes the connecting rod 36 which is fixedly connected with the upper end of the piston 31, the U-shaped rod 37 which is slidably connected with the connecting rod 36, and the abutment frame 32 which is fixedly connected with the U-shaped rod 37. The connecting rod 36 plays a limiting role on the U-shaped rod 37, and the U-shaped rod 37 can make the optical stress detector 18 move downward to a height close to the curtain wall glass, so that the distance between the optical stress detector 18 and the curtain wall glass is not too far in the process of driving the air suction component to move.

[0033] A rotating shaft 40 is rotatably installed inside the placing table 21, the rotating shaft 40 is provided with a threaded section 41, the threaded section 41 is threadedly connected with a positioning plate 42, the positioning plate 42 is slidably connected with the placing table 21, and the rotating shaft 40 is fixedly installed with a rotating handle 43. In the initial state, the rotating handle 43 drives the rotating shaft 40 and the threaded section 41 to rotate, and then the positioning plate 42 threadedly connected therewith is slid in the placing table 21 to adjust the position of the positioning plate 42, so that the front side of the curtain wall glass during placement can be limited, and the position of the detection point of the optical stress detector 18 on the curtain wall glass can be more accurately controlled.

[0034] A plurality of anti-skid strips 44 are installed on the upper end of the placing plate 24. The anti-skid strips 44 can play an anti-skid role.
