Description

Technical Field

[0001] The invention relates to the technical field of impact resistance testing of building safety glass, and in particular to a device and method for testing the impact resistance of a glass shot bag. Background Art

[0002] Shotbag impact performance is a mandatory safety performance requirement for tempered glass and laminated glass. The shotbag impact test is a test method to judge the breakage and protective performance of tempered glass and laminated glass when impacted by large soft heavy objects such as human body. This test method is suitable for quality and safety reliability testing of glass samples in parts such as glass windows, glass curtain walls and glass doors. It is currently the only method to distinguish safety laminated glass and the classification of safety glass.

[0003] When testing the impact performance of glass with a shot bag according to the current standard, testers will install the glass in a vertical manner, which can easily lead to unstable installation and cause glass shattering and injuring people, increasing safety hazards; the lowering height of the shot bag is generally adjusted by manually pulling a rope, which increases labor consumption and reduces testing efficiency; the lowering height of the shot bag is usually determined by a manual ruler, which has a large error and reduces testing accuracy. When testing the impact performance of glass with soft and heavy objects, existing products often use manual tightening of fixing bolts to tighten the test piece, which cannot effectively adjust the compression amount of the rubber strip and is difficult to control the compression amount of the rubber strip at each point to remain the same, resulting in uneven force between the glass and the compressed rubber strip, affecting the test results of the glass. In addition, no effective measures have been taken to avoid secondary impact between the shot bag and the glass, which affects the evaluation of the impact performance of the glass shot bag and reduces the testing accuracy. Summary of the invention

[0004] In order to overcome the problems in the prior art that glass is inconvenient to install vertically, is easy to break, and the height of the shot bag needs to be manually adjusted with low precision, the present invention provides a glass shot bag impact performance testing device, including a mounting mechanism, a door driving mechanism and an impact mechanism, wherein;

[0005] The installation mechanism includes a main frame and an installation door body rotatably connected to one side of the main frame, a glass test piece is installed inside the installation door body, the door body driving mechanism is installed on the cross brace of the main frame, the door body driving mechanism is connected to the upper end of the installation door body through a steel wire rope, the door body driving mechanism lowers the steel wire rope to rotate the installation door body to a horizontal position, and the door body driving mechanism retracts the steel wire rope upward to rotate the installation door body to a vertical position;

[0006] The impact mechanism includes a shot bag and a lifting mechanism. When the installation door body is lowered to a horizontal position, the lifting mechanism drives the shot bag to move vertically upward away from the upper end of the installation door body. The lifting mechanism also includes an auxiliary motor and a suspension wire. The auxiliary motor is connected to the main frame. One end of the suspension wire is fixedly connected to the shot bag, and the other end is arranged outside the output end of the auxiliary motor.

[0007] The outer wall of the main frame is provided with a push-out cylinder, and the output end of the push-out cylinder is in contact with the upper end of the door body.

[0008] Preferably, a sliding assembly is also provided at the lower end of the mounting door body, and the sliding assembly includes a slide rail fixed on the horizontal plane and a slider horizontally slidably connected to the slide rail. The lower end of the mounting door body is hinged on the slider, and the slider drives the mounting door body to move closer to or away from the main frame.

[0009] The door body can be installed and rotated between vertical and horizontal positions, so that the glass can be installed in the horizontal position and tested in the vertical position, effectively avoiding the risk of vertically installed glass being easily broken.

[0010] Preferably, it also includes a frame lifting mechanism, which includes a first roller, a second stepping motor driving the first roller to rotate, a first steel wire rope and an automatic clamping assembly;

[0011] One end of the first steel wire rope is wound on the first drum, and the other end is wound on the first fixed pulley and the movable pulley and then connected to the main frame. The movable pulley is connected with a hook, and the hook is hung on the automatic clamping assembly. The automatic clamping assembly includes a finger cylinder, and the mechanical clamp at the end of the finger cylinder can be movably opened and closed to clamp and release the shot bag.

[0012] The shot bag is lifted by the auxiliary frame, which changes the traditional manual rope lifting method. In addition, the clamping and release of the shot bag are controlled by the finger cylinder, which avoids the irregular movements and dangers of manual lifting and release. At the same time, the auxiliary motor and electric push rod are used together to lift the shot bag and place it on the electric push rod when installing the glass, ensuring the safety of the installers.

[0013] Preferably, the frame lifting mechanism includes a roller, and the roller is installed on the inner wall of the main frame. The frame lifting mechanism also includes an encoder for recording the number of rotations of the roller.

[0014] The use of stepper motor and electric traction reduces manpower input and effectively improves detection efficiency. At the same time, the encoder measures the rising height of the first wire rope and outputs pulse digits to the PLC program end. By writing the PLC control program, precise digital control of the shotbag height is achieved, avoiding the non-standard errors of traditional manual measuring scales.

[0020] Preferably, it also includes a PLC control device, which is communicatively connected with the encoder and the second drive member. The PLC control device calculates the falling time of the shot bag through the encoder and starts the second drive member after the shot bag falls.

[0021] The second drive unit is electrically driven to set a specific time interval. After a collision, the motor quickly pulls the second steel wire rope to move the shot bag away from the glass surface, thereby effectively avoiding a secondary collision between the shot bag and the glass. At the same time, it keeps the inspectors away from the test area to ensure safety.

[0022] Preferably, the automatic clamping assembly also includes an auxiliary frame and an electric push rod, one end of the auxiliary frame is hinged to the main frame, and a finger cylinder is fixedly installed on the outer wall of the other end, and a hook is hung on the auxiliary frame, the electric push rod is fixedly installed on the inner wall of the main frame, and the output end of the electric push rod is in contact with a side of the auxiliary frame where the finger cylinder is installed.

[0023] Preferably, a rotary clamping cylinder is installed on the outer wall of the main frame, and the rotary clamping cylinder includes a seat body, a cylinder, a connecting clamp block and a rubber pad;

[0027] S1. Start the third driving member to move the wire rope downward, and start the push-out cylinder to push the upper end surface of the installation door body to make the installation door body fall sideways.

[0028] S2. Place the glass test piece inside the installation door body.

[0029] S3. Push the cylinder back to its original position, and start the third drive member again to move the wire rope upward to lift the door body to a vertical position.

[0030] S4. Start the rotary clamping cylinder to clamp and install the door body and glass specimen.

[0045] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Therefore, the following detailed description of the embodiments of the present invention provided in the drawings is not intended to limit the scope of the claimed invention, but merely represents the selected embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0046] The present invention will be further described below in conjunction with the accompanying drawings and embodiments, and the specific embodiments are as follows:

[0047] like Figures 1 to 4 As shown, the present invention provides a glass shot bag impact performance testing device, comprising a mounting mechanism 1, a door body driving mechanism 2 and an impact mechanism 3. The mounting mechanism 1 comprises a main frame 101 and a mounting door body 102 rotatably connected to one side of the main frame 101. The main frame 101 is in an "L"-shaped structure. The lower end of the mounting door body 102 is hinged to a slider 103, and the other end is in contact with a push-out cylinder 206. A glass test piece 106 (5) is mounted inside the mounting door body 102. The main frame 101 comprises a vertical frame and a horizontal frame. A horizontal brace is arranged on the outer side of the horizontal frame. The horizontal brace is used to The third driving member 201 is installed, the door driving mechanism 2 is installed on the cross brace of the main frame 101, and the door driving mechanism 2 is connected to the upper end of the door body 102 through the steel wire rope 204. The door driving mechanism 2 lowers the steel wire rope 204 to rotate the door body 102 to a horizontal position, and the door driving mechanism 2 retracts the steel wire rope 204 to rotate the door body 102 to a vertical position. The impact mechanism 3 includes a shot bag 304 and a lifting mechanism. When the door body 102 is lowered to a horizontal position, the lifting mechanism drives the shot bag 304 to move vertically upward away from the upper end of the door body 102;

[0048] When testing is required, the installation door body 102 is first adjusted to a horizontal position to install the glass test piece 106 (5), and then the installation door body 102 is adjusted to a vertical position, which effectively avoids the safety risk of the vertically installed glass test piece 106 (5) being prone to cracking and ensures the safety of the test personnel;

[0049] The lower end of the door body 102 is hingedly connected to the sliding assembly, which includes a slide rail 104 fixed on a horizontal plane and a slider 103 slidably connected to the slide rail 104. The lower end of the door body 102 is hingedly connected to the slider 103. The arrangement of the slide rail 104 and the slider 103 can adapt to the installation of glass of different thicknesses to prevent the glass from being squeezed, deformed and cracked. After the installation is completed, the cylinder 106 (2) is started, and the cylinder 106 (2) drives the connecting clamp 106 (3) and the rubber pad 106 (4) to fit the door body 102 to clamp the specimen and the door body 102. At the same time, multiple rubber strips are arranged between the door body 102 and the main frame 101, so that when a collision occurs, the rubber strips at each point are evenly compressed to ensure that the glass specimen 106 (5) is evenly stressed.

[0050] The outer wall of the main frame 101 is installed with a push-out cylinder 206, and the output end of the push-out cylinder 206 is in contact with the upper end of the installation door body 102. The push-out cylinder 206 pushes out and cooperates with the third driving member 201 to electrically drive to realize the outward tilting function of the installation door body 102. The start of the third driving member 201 is controlled by the PLC program, and has the functions of precise positioning and stopping in place, thereby improving the efficiency of glass loading and unloading;

[0051] Specifically, the present application also includes a frame lifting mechanism 4, which includes a first roller 403, a stepper motor 401 for driving the first roller 403 to rotate, a first steel wire rope 407 and an automatic clamping assembly, one end of the first steel wire rope 407 is wound around the first roller 403, and the other end is wound around a first fixed pulley 406 and a movable pulley 408 and then connected to the lower end of the horizontal frame, the movable pulley 408 is connected to a hook 409, and the hook 409 is hung on the automatic clamping assembly, and the automatic clamping assembly includes a finger The finger cylinder 302, the mechanical gripper at the end of the finger cylinder 302 can be opened and closed to clamp and release the shot bag 304, the finger cylinder 302 is fixed to the lower end of the auxiliary frame 301, and the mechanical gripper at the end can be opened and closed to clamp and release the shot bag 304. The shot bag 304 has buckles at the upper and lower ends, the upper end buckle is connected to the suspension line 305, and the lower end buckle is connected to the second wire rope 504. The suspension line 305 is tied to the upper end of the main frame 101. The lifting mechanism also includes an auxiliary motor 306 and the suspension line 305. The auxiliary The motor 306 is connected to the main frame 101. One end of the suspension wire 305 is fixedly connected to the shot bag 304, and the other end is arranged outside the output end of the auxiliary motor 306. Before installing the glass test piece 106 (5), the auxiliary motor 306 is started, and the shot bag 304 is lifted to a certain height. Then, the electric push rod 108 is extended to support the shot bag 304, and then the glass test piece 106 (5) is installed. When the glass test piece 106 (5) is installed, the auxiliary motor 306 is started, and the shot bag 304 is lowered to the test piece. The shot bag 304 is moved to the test position by controlling the finger cylinder 302, and then the auxiliary frame 301 is lifted to drive the shot bag 304 to rise. After reaching the specified height, the finger cylinder 302 is released, so that the shot bag 304 is suspended by the suspension wire 305 and impacts the glass test piece 106 (5). By using the frame to assist in lifting, the manual rope lifting method is eliminated. At the same time, the finger cylinder 302 is used to release the shot bag 304, which reduces the interference of the manual rope release on the free fall of the shot bag 304.

[0052] Specifically, the frame lifting mechanism 4 of the present application includes a roller 405, and the roller 405 is installed on the inner wall of the main frame 101. The frame lifting mechanism 4 also includes an encoder 404 for recording the number of rotations of the roller 405. When the auxiliary frame 301 needs to be lifted, the stepper motor 401 is started, and the auxiliary frame 301 is driven to rise by pulling the first steel wire rope 407, which effectively saves manpower and time. At the same time, the rising height of the first steel wire rope 407 is measured by the encoder 404, and the rising height is calculated by the number of rotations of the roller 405 driven by the first steel wire rope 407. The PLC program end controls the output pulse number of the encoder 404 to achieve digital and precise control of the rising height, eliminating the irregular errors of traditional manual measuring rulers.

[0053] Specifically, the present application further includes an anti-rebound mechanism 5, which includes a second roller 503, a second driving member 501 for driving the second roller 503 to rotate, and a second steel wire rope 504. One end of the second steel wire rope 504 is wound around the second roller 503, and the other end is fixedly connected to the lower end of the shot bag 304. The PLC control device is in communication with the encoder 404 and the second driving member 501. The PLC control device calculates the falling time of the shot bag 304 through the encoder 404, and starts the second driving member 501 after the shot bag falls. Before the shot bag 304 collides with the glass, the falling time is reversely calculated from the falling height, and a time interval is set accordingly. By writing a PLC logic program, the second driving member 501 is quickly started when the time interval is reached, so that the second steel wire rope 504 is quickly contracted, driving the shot bag 304 away from the surface of the glass test piece 106 (5), thereby avoiding a secondary impact.

[0054] In addition, during the test, the third driving member 201 is first started to move the steel wire rope 204 downward, and at the same time, the push-out cylinder 206 is started to push the upper end surface of the installation door body 102 so that the installation door body 102 is tilted to a horizontal position to facilitate the installation of the glass. The glass test piece 106 (5) is placed inside the installation door body 102, and the push-out cylinder 206 is reset. The third driving member 201 is started again to move the steel wire rope 204 upward to lift the installation door body 102 to a vertical position, and the rotary clamping cylinder 6 is started to clamp the installation door body 102 and the glass test piece 106 (5) to fix. At the same time, the contact surface between the main frame 101 and the glass test piece 106 (5) is provided with adhesive tape, and the adhesive surface should be evenly bonded to the glass test piece 106 (5). 06(5) The bonding ensures that the impact force is evenly transmitted. The stepper motor 401 is started to cooperate with the first steel wire rope 407 to drive the finger cylinder 302 and the shotgun bag 304 to rise to the specified height for testing. The corresponding test height is selected according to the type of glass. The test height of tempered glass is directly up to 1200mm. The test heights of laminated glass are 300mm, 750mm and 1200mm respectively. The test height is gradually increased from low to high. The finger cylinder 302 is released to allow the shotgun bag 304 to collide with the glass for testing. Unbroken glass can be tested repeatedly and the test height can be increased. However, it is necessary to ensure that there are no obvious cracks on the glass specimen to ensure accurate test results.

[0055] The present invention also provides a method for testing the impact performance of a glass shot bag, and the specific implementation steps are as follows:

[0056] S1. When it is necessary to test the performance of the glass shot bag, start the auxiliary motor 306, lift the shot bag 304, and then extend the electric push rod 108 to support the shot bag 304 so as to install the glass test piece 106 (5). S2. Then start the third driving member 201 and the push cylinder 206 at the same time, tilt the door body 102 outward until it is in a horizontal position and then stop, and place the glass test piece 106 (5) stably on the installation door body 102; S3. Start the third driving member 201 to lift the mounting door body 102 until it reaches the vertical position and then stop. S4. Then start the rotary clamping cylinder 6 so that the cylinder 106 (2) drives the connecting clamp block 106 (3) and the rubber pad 106 (4) to fit the mounting door body 102, fix and clamp the glass test piece 106 (5); S5. Start the auxiliary motor 306, retract the electric push rod 108, lower the shotgun bag 304 to the test position, and then start the stepping motor 24. 01, through the first roller 403, the first steel wire 407 is retracted, thereby lifting the auxiliary frame 301, driving the shot bag 304 to rise, and the first steel wire 407 drives the roller 405 to rotate. According to the number of rotations of the roller 405, the encoder 404 sends pulses to the PLC program control terminal, and the height algorithm is edited and set to count the number of pulses received. When the specified pulse amount is reached, the stepper motor 401 is turned off, and the height of the shot bag 304 reaches the set height; S6. After reaching the set height, the time interval for dropping and lifting the ball is set, and then the pressure of the finger cylinder 302 is released, so that the shot bag 304 is freely released to collide with the glass specimen 106 (5); from the moment of releasing the shot bag 304, when the specified time interval for dropping and lifting the ball is reached, the second driving member 501 is quickly started, and the second steel wire 504 pulls the shot bag 304 to quickly leave the surface of the glass specimen 106 (5), thereby avoiding secondary collision after the collision test.
