DETAILED DESCRIPTION

[0033] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0034] In one embodiment, referring to Figures 1 to 10A device for testing the impact resistance of concrete components comprises a base 1, a top plate 6 is installed on the top of the base 1 through an installation side plate 3, a lifting shell 7 is arranged on the top of the base 1, an impact component 10 is arranged on the bottom end of the lifting shell 7, and a plurality of placement side plates 9 are arranged on the outer walls of both sides of the lifting shell 7 for placing a counterweight 8; a lifting mechanism 4 is arranged on the top of the base 1 for driving the lifting shell 7 to move up and down; a placement rack 24 is arranged on the side of the installation side plate 3 close to the lifting shell 7 for placing the counterweight 8, and a loading mechanism 5 is arranged on the side of the installation side plate 3 for loading the counterweight 8 on the placement rack 24 onto the placement side plate 9; a plurality of horizontally arranged rotating shafts 20 are arranged through the side of the lifting shell 7, and the rotating shafts 20 extend to both ends of the lifting shell 7. A connecting plate 19, a driving mechanism 21 is arranged inside the lifting shell 7, which is used to drive the rotating shaft 20 to rotate; a connecting groove 16 is provided on the side of the counterweight block 8 close to the lifting shell 7, and positioning grooves 17 are respectively provided on the inner walls on both sides of the connecting groove 16, which are used to accommodate and position the two ends of the connecting plate 19 when the rotating shaft 20 and the connecting plate 19 are horizontally rotated 90°; a movable plate 15 is installed on the inner wall of one end of the connecting groove 16 through a spring, and a flexible airbag 18 is arranged on the side of the movable plate 15 away from the lifting shell 7; the top and bottom of the counterweight block 8 are provided with anti-slip airbags 12 arranged at intervals, and the top and bottom of the counterweight block 8 are provided with transition chambers 14, the interior of the transition chamber 14 is connected with the interior of the flexible airbag 18, and the interior of the transition chamber 14 is connected with the interior of the anti-slip airbag 12 through a connecting hole 13.

[0035] When in use, the concrete component to be tested is placed on the top of the base 1. According to the requirements of the test, the counterweight 8 on the placement frame 24 can be pushed and loaded to the top of the placement side plate 9 through the loading mechanism 5. When the counterweight 8 is horizontally pushed and loaded to the top of the placement side plate 9, the connecting plate 19 is inserted into the inside of the connecting groove 16. As the counterweight 8 moves horizontally, the connecting plate 19 pushes the movable plate 15 and squeezes the flexible airbag 18. At this time, the air in the flexible airbag 18 is compressed and flows into the transition cavity 14 and the anti-skid airbag 12, so that the anti-skid airbag 12 is inflated and expanded. When the connecting plate 19 is located at the opening of the positioning groove 17, the driving mechanism 21 drives the rotating shaft 20 and the connecting plate 19 to rotate 90° until the two ends of the connecting plate 19 are respectively stuck in the inside of the positioning groove 17, so as to achieve effective connection between the counterweight 8 and the lifting shell 7. After the counterweight 8 is loaded, the lifting mechanism 4 drives the lifting shell 7 to move upward to the required height. During the test, the lifting mechanism 4 is separated from the lifting shell 7, so that The lifting shell 7, the counterweight 8 and the impact component 10 are in free fall and perform impact detection on the concrete member, that is, the anti-skid airbag 12 that is automatically inflated and expanded as the counterweight 8 is loaded can increase the friction between the counterweight 8 and the placement side plate 9, and also effectively fill the gap between the counterweight 8 and the placement side plate 9. On the basis that the counterweight 8 is connected to the lifting shell 7 through the connecting plate 19, when the lifting shell 7, the counterweight 8 and the impact component 10 fall and impact the concrete member, the anti-skid airbag 12 effectively prevents the counterweight 8 from shaking relative to the lifting shell 7 under the action of inertia, thereby preventing the rotating shaft 20 from being broken and the placement side plate 9 from being broken by impact, further ensuring that the counterweight 8 falls off during the impact test, and the loading and unloading of the counterweight 8 does not require manual handling operations, thereby improving safety, and the intensity of the detection can be adjusted by changing the number of counterweights 8 loaded on the placement side plate 9 and changing the height of the lifting shell 7 when it falls, which is flexible and convenient to use.

The lifting screw 41 can be driven to rotate by the driving motor 43, thereby driving the lifting sleeve 42 and the lifting shell 7 to move upward. After the lifting of the lifting shell 7 is completed, when detection is required, it can be reset horizontally by the telescopic component 44 until the connecting component 45 is separated from the connecting component 46, and the lifting shell 7 falls freely.
