Description

TECHNICAL FIELD

[0002] Most of the existing load-bearing walls on the market are made of reinforced concrete, and the outer surface of the load-bearing wall is concrete, so that when the load-bearing wall is accidentally impacted, damage or collapse is prone to occur, thereby endangering the safety of the building. Therefore, after the concrete block is made, a strength detection device needs to be used to detect the strength of the concrete block.

[0003] The existing patent (publication number: CN218382044U) discloses a concrete block strength impact detection device, which relates to the technical field of concrete detection and comprises a support table and a protective side plate. The protective side plate is installed on one side of the upper end of the support table. A concrete wall block is placed on one side of the support table close to the protective side plate. A fixing frame is installed at the rear end of the support table. A forward and reverse motor is installed in the fixing frame. The output end of the forward and reverse motor is connected with a rotating shaft. The end of the rotating shaft away from the forward and reverse motor is connected with a hammer. The lower end of the concrete wall block is inserted into the inner side of the anti-extraction groove for limiting. The anti-extraction plate can be clamped on the upper end of the concrete wall block by the lower end slot, so that the upper end of the concrete wall block of different heights can be fixed and limited without manual support. The forward and reverse motor can drive the rotating shaft to adjust the forward and reverse rotation and swing left and right. When the rotating shaft swings left and right, the fixed plate can swing synchronously with the rotating shaft, so as to drive the hammer to swing left and right and impact the concrete wall block for detection.

[0004] The impact block driven by the motor in the above-mentioned comparative document is used to impact the concrete block for detection. Although the structure is simple and the cost is low, the impact block driven by the motor usually needs a certain time to reach the preset speed and force, which may cause delay of impact and is difficult to simulate the case of instantaneous large impact force. In addition, the precision of adjusting the impact force size by adjusting the motor speed is not high enough. In order to solve the above-mentioned problems, a concrete block strength impact detection device is proposed. Practical new type content
