[0002] The quality of a construction project refers to the comprehensive requirements for the project's safety, applicability, economy, environmental protection, aesthetics and other characteristics in the country's current laws, regulations, technical standards, design documents and contracts. Before construction, in order to ensure that the building's service life, safety and other parameters are qualified, it is necessary to test parameters such as the structural strength of the building materials to be used in the building.

[0021] A handle 18 is installed on the side wall of the acceptance plate 10 on the side opposite to the lifting slide 11. The handle 18 is convenient for the operator to control the movement of the acceptance plate 10 and the wheel seat 13. A control panel 19 is arranged on the handle 18.

[0023] As a preferred embodiment of the present invention, refer to Figure 5The acceptance knocking assembly 12 includes an acceptance knocking box installed at the end of an electric telescopic rod 23. The acceptance knocking box has two through holes on one side facing the wall. A hammer rod 24 is telescopically arranged inside the through hole. A hammer head 26 with an arc structure is installed at the outer end of the hammer rod 24. The hammer head 26 contacts the wall for knocking. The fullness of the wall and the nature of the material used are detected according to the sound emitted by the knocking. The inner end of the hammer rod 24 extends to the inside of the acceptance knocking box. A spring connecting plate 27 is installed on the hammer rod 24 placed inside the acceptance knocking box. A plurality of springs 28 are connected in an annular manner at equal intervals between the spring connecting plate 27 and the corresponding inner wall of the acceptance knocking box. Under the elastic action of the spring 28, the hammer rod 24 is kept retracted to the inside of the acceptance knocking box. At the same time, a circulating pushing assembly is arranged inside the acceptance knocking box at the inner ends of the two groups of hammer rods 24. The circulating pushing assembly intermittently applies an outward thrust to the hammer rod 24, and then cooperates with the resilience of the spring 28 to realize the cyclic reciprocating movement of the hammer head 26, and perform cyclic knocking detection on the wall.

A protruding rod 30 is installed on the circumferential side wall of the wheel disc 29. When the wheel disc 29 rotates to control the protruding rod 30 to move to the inner end of the hammer rod 24, an outward thrust is applied to the hammer rod 24, thereby pushing the hammer head 26 to move.

[0026] Specifically, the outer surface of the hammer head 26 is wrapped with a layer of buffer pad to reduce the damage to the wall when it comes into contact with the wall.

[0027] The working principle of the utility model is: in the idle part of the device, all the driving parts mentioned above, which refer to power elements, electrical components and adapted power supplies, are connected through wires, and the electrical connections are completed in a sequential working order. The detailed connection means are well-known technologies in the field. The following mainly introduces the working principle and process, and does not explain the electrical control. When in use, according to the shape and position of the wall to be inspected and accepted, the operator holds the handle 18 to push the moving wheel 14 to move, and moves the acceptance plate 10 to one side of the wall. Then, according to the position of the locking nut 16 from the wall, the control panel 19 is controlled to start the electric telescopic rod 23 to adjust the initial position of the hammer head 26 to a suitable distance, and then the servo motor 20 is started to drive the screw 21 to rotate, and the servo motor 33 is started to drive the wheel 29 to rotate, and the spring 28 is used to control the two hammer heads 26 in each acceptance knocking box to move horizontally in a circular manner, and the wall is knocked in all directions. Then, the knocking sound is used to judge the material inside the wall and the internal structural space condition, and then judge whether it meets the acceptance standards.
