Description

Technical Field

[0001] This utility model relates to the field of glass curtain wall stability testing technology, and more specifically, to a rapid positioning glass curtain wall stability testing instrument. Background Technology

[0002] Glass curtain walls, with their transparent and lightweight texture, imbue buildings with a modern and technological feel. Through optical properties such as reflection and refraction, they interact with the natural environment, forming a unique visual identity. Their customizable designs can meet the needs of different architectural styles and enhance the layering of the urban landscape. The robustness of glass curtain walls is a core indicator for ensuring building safety. During their service life, curtain walls must withstand cyclic loads such as wind vibration and temperature differences. Wind pressure resistance testing can assess their fatigue performance and deformation capacity, preventing problems such as leakage and detachment caused by material aging and sealing failure.

[0003] Currently, the robustness test of glass curtain walls is only convenient to be conducted in the laboratory. However, the test data from the laboratory cannot truly reflect the robustness quality of the curtain wall after actual installation, and needs to be improved. Therefore, we propose a rapid positioning glass curtain wall robustness tester. Utility Model Content

[0004] In view of the above-mentioned technical problems in related technologies, this utility model provides a rapid positioning glass curtain wall stability tester, which can solve the above problems.

[0005] To achieve the above-mentioned technical objectives, the technical solution of this utility model is implemented as follows:

[0006] The rapid positioning glass curtain wall stability tester includes a fixed bracket, a motor mounting bracket, a linear stepper motor, a column-type tension sensor, a flange connector, and a vacuum suction cup. The fixed bracket includes four cross-shaped support rods with adjustment grooves. Pads are slidably installed inside the adjustment grooves, and the four pads support the inner surface of the glass curtain wall frame. The vacuum suction cup is attached to the inner surface of the curtain wall glass and includes a suction cup head, a vacuum pump, and a valve body. The push rod end of the linear stepper motor is securely connected to the flange connector via the column-type tension sensor. The flange connector is securely connected to the suction cup head of the vacuum suction cup. Both the column-type tension sensor and the linear stepper motor are electrically connected to the controller via wires.

[0007] Furthermore, a screw rod is fixedly installed on the back of the pad block, which is in contact with the inside of the adjustment groove, and the screw rod surface is threaded with nuts distributed on the front and rear sides of the support rod.

[0008] Furthermore, the column-type tension sensor has internal threaded holes at both the front and rear ends, and one end of the flange connector and the push rod end of the linear stepper motor are respectively provided with screw sections that mate with the internal threaded holes of the column-type tension sensor.

[0009] Furthermore, the motor mounting bracket is fitted onto the outside of the linear stepper motor and fastened with bolts, and a handle is fixedly installed on the outer surface of the motor mounting bracket.

[0010] Furthermore, both the column-type tension sensor and the linear stepper motor are located on one side of the back of the fixed bracket, and the flange connector runs through the middle of the fixed bracket.

[0011] Furthermore, each of the four pads has a 2mm thick rubber pad fixedly installed on the side facing the glass curtain wall frame.

[0012] The beneficial effects of this utility model are as follows: The vacuum suction cup of this device is adsorbed onto the curtain wall glass, and the position adjustable pad is adjusted to abut against the surface of the glass curtain wall frame. The linear stepper motor applies tension to the vacuum suction cup through the column-type tension sensor and flange connector, which can detect the firmness between the curtain wall glass and the glass curtain wall frame. The column-type tension sensor can monitor the tension value in real time to avoid damage to the curtain wall glass caused by excessive tension. Attached Figure Description

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model are within the protection scope of the present utility model.

[0020] like Figure 1-2 As shown, this utility model discloses a rapid positioning glass curtain wall stability tester, including a fixed bracket 1, a motor mounting bracket 3, a linear stepper motor 4, a column-type tension sensor 9, a flange connector 8, and a vacuum suction cup 5. The motor mounting bracket 3 is fixed to the back of the fixed bracket 1. The fixed bracket 1 includes four cross-shaped support rods 101, each with an adjustment groove 102. Pads 2 are slidably disposed inside the adjustment grooves 102. The four pads 2 support the inner surface of the glass curtain wall frame 7. The vacuum suction cup 5 is adsorbed onto the inner surface of the curtain wall glass 6. The vacuum suction cup 5 includes a suction head, a vacuum pump, and a valve. The linear stepper motor 4 has its push rod end fastened to the flange connector 8 via a column-type tension sensor 9. The flange connector 8 is fastened to the suction head of the vacuum suction cup 5. Both the column-type tension sensor 9 and the linear stepper motor 4 are electrically connected to the controller via wires. A screw 201 is fixedly installed on the back of the pad 2, which is in contact with the inside of the adjustment groove 102. Nuts 202 distributed on the front and back sides of the support rod 101 are threaded onto the surface of the screw 201. Both the column-type tension sensor 9 and the linear stepper motor 4 are located on one side of the back of the fixed bracket 1. The flange connector 8 passes through the middle of the fixed bracket 1.

[0021] Example 1: The suction head shell of the vacuum suction cup 5 is fastened to the flange portion of the flange connector 8 by bolts. Both the column portion of the flange connector 8 and the push rod end of the linear stepper motor are provided with threaded sections that mate with the threaded holes at both ends of the column-type tension sensor 9. The column-type tension sensor 9 is a CPR12 tension sensor from Koprei. Both ends of the column-type tension sensor 9 have internal threaded holes for connecting the column portion of the flange connector 8 and the push rod of the linear stepper motor 4, respectively. The working principle of the column-type tension sensor 9 is based on the resistance strain effect. When the elastic body is subjected to force, it deforms, causing a change in the resistance value of the strain gauge attached to its surface, thereby converting the tension signal into an electrical signal output. Therefore, in the linear stepper motor 4... The push rod retracts to provide tension, which is transmitted to the vacuum suction cup 5 through the column-type tension sensor 9 and the flange connector 8. The fixed bracket 1 will generate a reaction force, causing the pad 2 to press against the surface of the glass curtain wall frame 7. The electrical signal of the column-type tension sensor 9 is transmitted to the controller, which integrates a processor and a display screen for processing and displaying the tension value. The movement of the linear stepper motor 4 is independently controlled by the controller. The suction head of the vacuum suction cup 5 is connected to the vacuum pump through a vacuum pipe. A valve body is installed in the pipe to control the maintenance and release of the vacuum. The screw 201 can slide to adjust its position in the adjustment groove 102. When the position of the pad 2 and the surface of the glass curtain wall frame 7 is determined, tightening the two nuts 202 on the screw 201 can limit the overall position of the screw 201 and the pad 2.

[0022] In the preferred technical solution, the column-type tension sensor 9 has internal threaded holes at both the front and rear ends. One end of the flange connector 8 and the push rod end of the linear stepper motor 4 are respectively provided with screw sections that cooperate with the internal threaded holes of the column-type tension sensor 9. The column-type tension sensor 9 is used to connect the flange connector 8 and the linear stepper motor 4, so as to record the tension value in real time during the test of firmness and avoid damage to the curtain wall glass 6 caused by excessive tension.

[0023] In the preferred technical solution, the motor mounting bracket 3 is sleeved on the outside of the linear stepper motor 4 and fastened with bolts. A handle 301 is fixedly provided on the outer surface of the motor mounting bracket 3, and the handle 301 is provided to facilitate holding the device.

[0024] In the preferred technical solution, each of the four pads 2 is fixedly provided with a 2mm thick rubber pad on the side facing the glass curtain wall frame 7. The rubber pad is used to prevent the glass curtain wall frame 7 from being scratched or damaged.

[0025] In practical use, the handheld handle 301 is used to bring the pad 2 into contact with the four edges of the glass curtain wall frame 7. The vacuum pump is started to make the suction head of the vacuum suction cup 5 firmly adhere to the curtain wall glass 6. The controller controls the push rod of the linear stepper motor 4 to retract, and the column-type tension sensor 9 detects the tension value. During the process, the tension value is displayed on the controller's screen. When the upper limit of the standard value of the curtain wall glass 6's firmness performance is reached, the retraction action of the linear stepper motor 4 stops. Finally, the push rod of the linear stepper motor 4 is slowly pushed back to reset, releasing the tensile stress of the curtain wall glass 6. The adjustable position of the pad 2 of this device facilitates quick positioning of the glass curtain wall frame 7. Combined with the vacuum suction cup 5, the column-type tension sensor 9, and the linear stepper motor 4, the firmness of the glass curtain wall is detected to ensure the safety of the glass curtain wall in subsequent use.

[0026] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
