Description

Technical Field

[0001] This invention belongs to the field of building exterior wall inspection technology, and specifically relates to a device for testing the stability of exterior walls of prefabricated steel structure buildings. Background Technology

[0002] The stability testing device is used to test the exterior walls of prefabricated steel structure buildings. If the installation is not standardized or not carried out in accordance with regulations, the stability of the exterior walls of the prefabricated steel structure building will be poor, thus failing to meet safety standards, and there will be a greater risk of continuing to install or live in the building.

[0003] Patent CN202210816459.3 mentions a device for detecting the stability of the exterior wall of a prefabricated steel structure building. It uses a motor to drive multiple suction cups to rotate in order to detect whether the prefabricated exterior wall has deflected or moved. However, it is rare for the prefabricated exterior wall to be not completely fixed. In more cases, the suction cups remain stationary, which blocks the motor and prevents it from working. This can easily lead to excessive load on the motor and cause it to burn out.

[0004] Therefore, it is necessary to invent a device for testing the stability of the exterior walls of prefabricated steel structure buildings to solve the above problems. Summary of the Invention

[0005] To address the aforementioned problems, this invention provides a device for testing the stability of the exterior walls of prefabricated steel structure buildings, thereby resolving the issues raised in the background section.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a stability testing device for the exterior wall of a prefabricated steel structure building, comprising a movable platform and a counterweight base. The bottom of the counterweight base is provided with multiple movable wheels, and the top of the counterweight base is provided with a mounting shell. A display screen is provided on the front side of the mounting shell, and a first hydraulic telescopic rod is provided inside the mounting shell. The output end of the first hydraulic telescopic rod is fixedly connected to the bottom of the movable platform. A second hydraulic telescopic rod is provided at one end of the movable platform, and a rotating platform is provided at the other end of the movable platform. A working motor is provided on one side of the movable platform, and a transmission mechanism is provided between the movable platform and the rotating platform.

[0007] Two connecting rods are provided on each side of the rotating platform. Folding rods are provided at the ends of the four connecting rods. Movable rods are movably inserted into the ends of the four folding rods. An electromagnetic block is provided at one end of the movable rod. The electromagnetic block is connected to the energy storage battery inside the mounting shell through a circuit. A return spring is provided at the other end of the movable rod.

[0008] Furthermore, the transmission mechanism includes a rotating shaft, one end of which is fixedly connected to a rotating table, and the other end of which is provided with a worm gear. A worm is meshed with the bottom of the worm gear, and one end of the worm is fixedly connected to a first bevel gear. A second bevel gear is provided on one side of the first bevel gear, and one end of the second bevel gear is fixedly connected to the output end of the working motor.

[0009] Furthermore, a push plate is provided at one end of the rotating platform, a soft pad is provided at one end of the push plate, and a push rod is provided at the other end of the push plate. One end of the push rod passes through the rotating platform and the rotating shaft and extends into the interior of the moving platform, and the end of the push rod is fixedly connected to the second hydraulic telescopic rod.

[0010] Furthermore, one end of the connecting rod and one end of the folding rod are hinged together. The end of the folding rod is provided with a insertion groove, and an arc-shaped rod is movably inserted into the insertion groove. One end of the arc-shaped rod is fixedly connected to the end of the connecting rod. Both sides of one end of the arc-shaped rod are provided with first friction plates, and both sides of the other end of the arc-shaped rod are provided with second friction plates.

[0011] Furthermore, the center line of the rotating shaft and the center line of the worm gear are the same straight line, and the transmission ratio between the worm gear and the worm is 1:8.

[0012] Furthermore, the first bevel gear meshes with the second bevel gear, and the diameter of the second bevel gear is 0.5 times the diameter of the first bevel gear.

[0013] Furthermore, the folding rod and the connecting rod are arranged in parallel, and the included angle between the connecting rod and the folding rod is in the range of 30-180 degrees.

[0014] Furthermore, the cushion is made of rubber, and the surface of the cushion is decorated with an uneven, wavy pattern.

[0015] Furthermore, both the first friction plate and the second friction plate are made of rubber, and both the surfaces of the first friction plate and the second friction plate are roughened.

[0016] The technical effects and advantages of this invention are as follows:

[0017] 1. This invention uses an electromagnetic block to adhere to and fix the wall surface. The worm gear and worm wheel reduce the speed of the motor while preventing the motor from directly acting on the rotating platform and thus being unable to move a heavy wall. Once the wall is completely fixed or has reached its maximum range of motion, the electromagnetic block's adsorption properties allow it to slide on the wall surface, effectively preventing the working motor from being blocked and unable to rotate. This ensures that the working motor will not be overloaded and burn out.

[0018] 2. The present invention uses a folding rod and a connecting rod to hinge together, which makes it convenient to fold and store the electromagnetic block and the folding rod. The first friction plate and the second friction plate are used to rub and fix them in two positions, which avoids the device being too large and inconvenient to transport. When not in use, the electromagnetic block is in contact with the surface of the soft pad, which prevents accidental activation of the electromagnetic block and adsorption of other iron-containing metal objects.

[0019] Other features and advantages of the invention will be set forth in the description which follows, and will be apparent in part from the description, or may be learned by practicing the invention. The objects and other advantages of the invention may be realized and obtained by means of the structures pointed out in the description and the drawings. Attached Figure Description

[0026] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0027] This invention provides a device for detecting the stability of the exterior walls of prefabricated steel structure buildings, such as... Figure 1-3As shown, it includes a mobile platform 1 and a counterweight base 2. The bottom of the counterweight base 2 is provided with multiple moving wheels 3. The top of the counterweight base 2 is provided with a mounting shell 4. The front side of the mounting shell 4 is provided with a display screen 5. The inside of the mounting shell 4 is provided with a first hydraulic telescopic rod 6. The output end of the first hydraulic telescopic rod 6 is fixedly connected to the bottom of the mobile platform 1. One end of the mobile platform 1 is provided with a second hydraulic telescopic rod 7. The other end of the mobile platform 1 is provided with a rotating platform 8. A working motor 9 is provided on one side of the mobile platform 1. A transmission mechanism is provided between the mobile platform 1 and the rotating platform 8.

[0028] Two connecting rods 10 are provided on both sides of the rotating platform 8. Folding rods 11 are provided at the ends of the four connecting rods 10. Movable rods 12 are movably inserted at the ends of the four folding rods 11. An electromagnetic block 13 is provided at one end of the movable rod 12. The electromagnetic block 13 is connected to the energy storage battery inside the mounting shell 4 through a circuit. A return spring 14 is provided at the other end of the movable rod 12.

[0029] The transmission mechanism includes a rotating shaft 15, one end of which is fixedly connected to a rotating platform 8. A worm gear 16 is provided at the other end of the rotating shaft 15, and a worm 17 is meshed with the bottom of the worm gear 16. The center line of the rotating shaft 15 and the center line of the worm gear 16 are the same straight line. The transmission ratio between the worm gear 16 and the worm 17 is 1:8. A first bevel gear 18 is fixedly connected to one end of the worm 17. A second bevel gear 19 is provided on one side of the first bevel gear 18. The first bevel gear 18 and the second bevel gear 19 mesh with each other. The diameter of the second bevel gear 19 is 0.5 times the diameter of the first bevel gear 18. One end of the second bevel gear 19 is fixedly connected to the output end of the working motor 9.

[0030] When a stability test of the wall is required, the entire device is moved to the front of the wall. The first hydraulic telescopic rod 6 is activated, causing the rotating platform 8 to move multiple electromagnetic blocks 13 to the working position. The device is moved further until the electromagnetic blocks 13 are in contact with the wall surface. The electromagnetic blocks 13 are then activated to adhere to the wall surface. If the electromagnetic blocks 13 move excessively, the movable rod 12 retracts backward, causing a small portion of the return spring 14 to be compressed and deformed. The counterweight base 2 effectively ensures the overall stability of the device, preventing the device from tipping over due to a change in the upper center of gravity. Subsequently, the working motor 9 is activated, causing the second bevel gear 19 to rotate. The first bevel gear 18 then drives the worm gear 17 to rotate, which in turn drives the worm wheel 16 to rotate. The rotating shaft 15 then... The rotating table 8 is driven to rotate. The transmission ratio between the worm gear 16 and the worm 17 is 1:8, and the diameter of the second bevel gear 19 is 0.5 times the diameter of the first bevel gear 18, which greatly reduces the rotation speed of the rotating table 8. At the same time, under the action of the worm 17 and the worm gear 16, the motor does not directly act on the rotating table 8. With the assistance of multiple connecting rods 10 and folding rods 11, multiple electromagnetic blocks 13 apply a certain pushing force to the wall. If the wall has poor stability, the wall will move slightly. If the wall has been completely fixed or has reached its maximum range of movement, the electromagnetic blocks 13 are pushed to slide slowly on the wall surface by utilizing the adsorption characteristics of the electromagnetic blocks 13, thus avoiding the situation where the working motor 9 is blocked from rotating.

[0031] This invention uses an electromagnetic block 13 to adhere to and fix the wall surface. The worm gear 17 and worm wheel 16 reduce the speed of the motor while preventing the motor from directly acting on the rotating platform 8 and thus being unable to move the heavy wall. Once the wall is completely fixed or has reached its maximum range of motion, the electromagnetic block 13 slides on the wall surface due to its adsorption properties. This effectively prevents the working motor 9 from being blocked and unable to rotate, thus ensuring that the working motor 9 will not be overloaded and burn out.

[0032] like Figure 1-3 As shown, a push plate 20 is provided at one end of the rotating table 8, and a soft pad 22 is provided at one end of the push plate 20. The soft pad 22 is made of rubber and has a corrugated surface. A push rod 21 is provided at the other end of the push plate 20. One end of the push rod 21 passes through the rotating table 8 and the rotating shaft 15 and extends into the interior of the moving table 1. The end of the push rod 21 is fixedly connected to the second hydraulic telescopic rod 7.

[0033] When testing the welded joint of the wall, the second hydraulic telescopic rod 7 operates, causing the push rod 21 to drive the push plate 20 to gradually approach the wall surface. After the soft pad 22 first adheres to the wall surface, the push plate 20 acts on the wall surface. If the wall weld is unstable, the welded joint will be pushed and deformed significantly. If the wall weld is stable, the soft pad 22 will be pushed and deformed slightly, preventing the device from being pushed in the opposite direction and tipping over. At the same time, the second hydraulic telescopic rod 7 has a limited feed length, so that the push plate 20 will not be pushed excessively and the soft pad 22 will be damaged excessively.

[0034] like Figure 4 As shown, one end of the connecting rod 10 is hinged to one end of the folding rod 11. The folding rod 11 and the connecting rod 10 are parallel. The included angle between the connecting rod 10 and the folding rod 11 is 30-180 degrees. The end of the folding rod 11 is provided with an insertion groove 23. An arc-shaped rod 24 is movably inserted into the insertion groove 23. One end of the arc-shaped rod 24 is fixedly connected to the end of the connecting rod 10. Both sides of one end of the arc-shaped rod 24 are provided with first friction plates 25. Both sides of the other end of the arc-shaped rod 24 are provided with second friction plates 26. Both the first friction plates 25 and the second friction plates 26 are made of rubber. The surfaces of the first friction plates 25 and the second friction plates 26 are roughened.

[0035] Before using the device, the retracted folding rod 11 is deflected so that it is parallel to the connecting rod 10. The insertion groove 23 is moved away from the surface of the two first friction plates 25 and moved to the surface of the two second friction plates 26. The two first friction plates 25 that have been squeezed and deformed are elastically restored to their original state, while the two second friction plates 26 are squeezed and deformed. At the same time, their rough surfaces rub and fix the folding rod 11.

[0036] The present invention uses a folding rod 11 to hinge with a connecting rod 10, which makes it convenient to fold and store the electromagnetic block 13 and the folding rod 11. The first friction plate 25 and the second friction plate 26 are used to rub and fix them in two positions, so as to avoid the device being too large and inconvenient to transport. When not in use, the electromagnetic block 13 is in contact with the surface of the soft pad 22, which prevents accidental activation of the electromagnetic block 13 and adsorption of other iron-containing metal objects.

[0037] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features; and these modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of the present invention.
