[0021] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0022] Example 1, please refer to Figures 1 to 4 The utility model provides a technical solution: a curtain wall bearing capacity detection device, including a control base 1, a detection protection frame 2 is fixedly connected to the top of the control base 1 near the left side thereof, a top plate 3 is fixedly connected to the top of the detection protection frame 2 through a bracket, an electric cylinder 4 is fixedly installed on the top of the top plate 3, the output end of the electric cylinder 4 is fixedly connected to a lower pressure plate 5 with a pressure sensor, a servo motor 6 is fixedly installed on the right side of the control base 1 near the inner wall thereof, a threaded rod 7 is fixedly connected to the output end of the servo motor 6, a threaded sleeve 8 is threadedly connected to the surface of the threaded rod 7, a curtain wall placement frame 9 with a pressure sensor is fixedly connected to the top of the threaded sleeve 8, a limiting component is connected to the bottom of the curtain wall placement frame 9, a groove is opened on the side of the inner wall of the detection protection frame 2, and an explosion-proof pressure-resistant plate 10 is fixedly installed on the inner wall of the groove.

[0023] Furthermore, the top of the lower pressure plate 5 is fixedly connected with a limiting telescopic rod 13, the top of the limiting telescopic rod 13 is fixedly connected to the bottom of the top plate 3, the number of the limiting telescopic rods 13 is at least four, and the at least four limiting telescopic rods 13 are evenly distributed between the lower pressure plate 5 and the top plate 3. Under the action of the limiting telescopic rod 13, the smooth anti-tilt lifting and lowering movement of the lower pressure plate 5 is guaranteed.

[0024] Furthermore, the limiting assembly includes a limiting plate 14 and a limiting groove 15, wherein the limiting plate 14 is fixedly connected to the bottom of the curtain wall mounting frame 9, and the limiting groove 15 is provided on the top of the control base 1, and the inner wall of the limiting groove 15 is slidably connected to the surface of the limiting plate 14. By setting the limiting plate 14 and the limiting groove 15, the movement trajectory of the threaded sleeve 8 is limited, so that the rotation of the threaded rod 7 can drive the threaded sleeve 8 to move.

[0025] Furthermore, a magnetic fixing groove 16 is opened on the right side of the detection and protection frame 2, and the front and rear sides of the curtain wall placement rack 9 are fixedly connected with a magnetic fixing plate 17. The surface of the magnetic fixing plate 17 and the inner wall of the magnetic fixing groove 16 are magnetically engaged and adapted. The magnetic fixing plate 17 and the magnetic fixing groove 16 are added for clamping and positioning to ensure that the curtain wall placement rack 9 is completely inserted and sealed in the detection and protection frame 2.

[0026] Example 2, please refer to Figures 1 to 4 The difference between this embodiment and embodiment 1 is that an anti-skid groove 11 is provided at the bottom of the lower pressure plate 5, and a single-point pressure contact 12 is clamped inside the anti-skid groove 11. The single-point pressure contact 12 can be clamped in the inner wall of the anti-skid groove 11 to detect the bearing capacity at a single point on the curtain wall. One side of the explosion-proof and pressure-resistant plate 10 is a stabilizing plate 18, and a shock absorber 19 is clamped inside the stabilizing plate 18. One end of the shock absorber 19 is fixedly connected to a wear-resistant protective plate 20. The surface of the stabilizing plate 18 is fixedly connected to a pressure-absorbing pad 21 with a collision sensor. If the curtain wall pops open due to exceeding the critical value during the downward pressure bearing capacity test, when the popped-up curtain wall fragments expand outward in the circumferential direction, the wear-resistant protective plate 20 on the explosion-proof and pressure-resistant plate 10 will be impacted first. Under the action of the shock absorber 19, force unloading and buffering are performed to avoid causing a large degree of impact and vibration. The collision sensor on the pressure-absorbing pad 21 can sense the impact of the wear-resistant protective plate 20, issue an alarm to notify the surrounding staff, and obtain the critical bearing capacity of the curtain wall.

[0027] Working principle: When the curtain wall bearing capacity detection device is in use, the bearing capacity pre-value is set before the pre-detection operation of the curtain wall to be detected, and then the curtain wall is placed on the curtain wall placement frame 9 for stable installation. The subsequent operation of the servo motor 6 can drive the threaded rod 7 to rotate. Through the setting of the limit plate 14 and the limit groove 15, the movement trajectory of the threaded sleeve 8 is limited, so that the rotation of the threaded rod 7 can drive the threaded sleeve 8 to move, and then the entire curtain wall placement frame 9 and the curtain wall are pushed into the interior of the detection protection frame 2. The magnetic suction plug-in plate 17 and the magnetic suction plug-in groove 16 are added for clamping and positioning to ensure that the curtain wall placement frame 9 is completely socketed and sealed in the detection protection frame 2. After the curtain wall is stably placed in the detection protection frame 2, the operation of the electric cylinder 4 can drive the lower pressure plate 5 to move downward to press the curtain wall below. According to the pressure sensor and the curtain wall placement inside the lower pressure plate 5 The pressure sensors in the mounting frame 9 obtain values ​​respectively, and combine the alignment to determine the pressure values ​​that the curtain wall can offset, thereby completing the detection of the overall bearing capacity of the curtain wall. If it is necessary to perform a pressure test bearing capacity of a single point in the area of ​​the curtain wall, the single-point pressure contact 12 can be clamped in the inner wall of the anti-slip groove 11 to detect the bearing capacity of a single point on the curtain wall. If the curtain wall pops open due to exceeding the critical value during the downward pressure bearing capacity test, when the popped-up curtain wall fragments expand outward in the circumferential direction, the wear-resistant protective plate 20 on the explosion-proof pressure-resistant plate 10 will be impacted first. Under the action of the shock absorber 19, force unloading and buffering are performed to avoid causing a large degree of impact and vibration. The collision sensor on the pressure buffer pad 21 can sense the impact of the wear-resistant protective plate 20, issue an alarm to notify the surrounding staff, and obtain the critical bearing capacity of the curtain wall, thereby ensuring accurate measurement and safety during the curtain wall bearing capacity detection process.
