Description

Technical Field

[0001] The present invention relates to the technical field of impact detection, and specifically to an impact detection device for building exterior enclosing walls. Background Art

[0002] The building exterior enclosing wall is an important part of a building. It not only supports the building but also plays a role in isolating the cold and hot air outside and ensuring the stability of the indoor temperature. The material impact strength testing machine is an instrument used in the fields of mechanics, basic disciplines of engineering and technical sciences, materials science, and civil engineering construction. It can effectively conduct impact tests on building materials. However, since the force application directions of most existing impact detection devices are relatively fixed and single, it is easy to occur that the bearing capacity of the building exterior enclosing wall is different under different placements, increasing the risk of use of the building exterior enclosing wall. Moreover, after some impact tests on the building exterior enclosing wall, manual comparison is carried out, increasing the misjudgment rate after the building exterior enclosing wall test, bringing inconvenience to the work of the staff and having a certain adverse impact on actual use.

[0012] Compared with the prior art, the present invention has the following beneficial effects:

[0013] 1. When the second drive motor starts, it can drive the bidirectional threaded rod to rotate.

The striking rod repeatedly strikes the building's exterior wall under the action of the sliding ring.

[0014] 2. When the hydraulic cylinder starts, it can drive the impact rod to move. The movement of the impact rod can drive the elastic sleeve on it to move, and the groove plate can slide smoothly on the inner wall of the chute plate, that is, the smooth sliding of the elastic sleeve is guaranteed. When the impact rod strikes the building's exterior wall and generates a reverse reaction force, the elastic sleeve can absorb part of the reaction force of the impact rod and perform the work of absorbing and removing the external force through the elastic folding frame, thus completing the secondary impact resistance test on the building's exterior wall;

[0015] 3. Through the setting of the plastic soft pad, the range that the fixed sleeve plate can adapt to is increased. When the driver starts, it can drive the first lead screw to rotate. Through the settings of the two linkage wheels and the linkage belt, the rotation of the first lead screw can drive the second lead screw to rotate at the same speed and in the same direction, and then achieve the relative vertical and stable movement of the first nut and the second nut. The first appearance detector and the second appearance detector can scan and record the surface of the building's exterior wall. Finally, the staff can calculate the impact resistance degree of the building's exterior wall. BRIEF DESCRIPTION OF THE DRAWINGS

Through the arrangement of the two linkage wheels 23 and the linkage belt 24, the rotation of the first screw rod 18 can drive the second screw rod 22 to rotate at the same speed and in the same direction. The surface of the second screw rod 22 is connected to a second nut 25, and the surface of the second nut 25 is fixedly installed with a second appearance detector 26. The first appearance detector 20 and the second appearance detector 26 can scan and record the surface of the outer wall of the building.

[0030] Example 3, please refer to Figures 1 to 6 , the difference between this embodiment and embodiment 1 is that: a driving machine 28 is fixedly installed on the rear side of the first detection box 1 through a bracket, and a bidirectional threaded rod 29 is fixedly connected to the output end of the driving machine 28. When the driving machine 28 is started, the bidirectional threaded rod 29 can be driven to rotate. The surfaces of different threads on the bidirectional threaded rod 29 are respectively threadedly connected with threaded sleeves 30, and the bottom of the threaded sleeve 30 is fixedly connected with a clamping plate 31. A through groove for the clamping plate 31 to pass through is provided on the surface of the rear side of the first detection box 1. The movement of the threaded sleeve 30 can drive the clamping plate 31 to move, thereby achieving the clamping and fixing of the outer protective wall of the building, reducing the movement of the outer protective wall of the building when it is hit. The top of the threaded sleeve 30 is fixedly connected with a limiting plate 32, and the surface of the first detection box 1 is provided with a limiting slot plate 33 that is slidably connected and adapted to the limiting plate 32.

[0031] Working principle: When the impact resistance detection device for the building exterior wall is in use, the staff can open the box door 2 to place the building exterior wall on the placing plate 8. Then, the staff can start the second drive 28. When the second drive 28 starts, it can drive the bidirectional threaded rod 29 to rotate. Through the settings of the limiting plate 32 and the limiting groove plate 33, the movement trajectory of the threaded sleeve plate 30 is limited, so that the rotation of the bidirectional threaded rod 29 can drive the threaded sleeve plate 30 thereon to move. The movement of the threaded sleeve plate 30 can drive the clamping plate 31 to move, thereby achieving the clamping and fixing of the building exterior wall, reducing the situation that the building exterior wall will move when being struck. Through the setting of the anti-slip plate 27, the placement stability of the building exterior wall is further guaranteed. When the first drive 3 starts, it can drive the bent rotating rod 4 to rotate. The rotation of the bent rotating rod 4 can drive the sliding ring 5 thereon to rotate and move up and down. Through the settings of the inner ring, outer ring and ball bearings, the smoothness of the sliding ring 5 during rotation is guaranteed, reducing the situation that the sliding ring 5 gets stuck on the bent rotating rod 4, ensuring that the striking rod 6 on the sliding ring 5 can always point downward under the action of gravity. The striking rod 6 strikes the building exterior wall repeatedly under the action of the sliding ring 5. The waste gas treatment box 15 can adsorb and discharge the dust generated by the internal strike through the exhaust pipe 14, reducing the situation of excessive dust in the first detection box 1 after the internal detection, thus completing the first impact resistance detection of the building exterior wall. When the hydraulic cylinder 12 starts, it can drive the impact rod 13 to move. The movement of the impact rod 13 can drive the elastic sleeve 37 thereon to move, and the groove plate 35 can slide smoothly on the inner wall of the chute plate 34, that is, the smooth sliding of the elastic sleeve 37 is guaranteed. When the impact rod 13 impacts the building exterior wall and generates a reverse reaction force, the elastic sleeve 37 can absorb part of the reaction force of the impact rod 13 and perform the absorption and removal of the external force through the elastic folding frame 36, thus completing the second impact resistance detection of the building exterior wall. After the impact resistance test of the building exterior wall is completed, the staff can clamp the building exterior wall into the fixed sleeve plate 16 for fixation. Through the setting of the plastic soft pad 21, the range that the fixed sleeve plate 16 can adapt to is increased. When the driver 17 starts, it can drive the first lead screw 18 to rotate. Through the settings of the two linkage wheels 23 and the linkage belt 24, the rotation of the first lead screw 18 can drive the second lead screw 22 to rotate at the same speed and in the same direction, thereby achieving the relative vertical and stable movement of the first nut 19 and the second nut 25. The first appearance detector 20 and the second appearance detector 26 can scan and record the surface of the building exterior wall. Finally, the staff can calculate the impact resistance degree of the building exterior wall, which brings convenience to the work of the staff.

[0032] Although embodiments of the present invention have been shown and described, it will be understood by those of ordinary skill in the art that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
