[0019] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0020] Example 1

[0021] A building seismic structure testing device, such as Figure 1 and Figure 2 As shown, it includes a mobile installation frame 1, a driving motor 2 is installed on the right side of the mobile installation frame 1, the output shaft of the driving motor 2 is set to face left, a knocking component 4 is installed on the top of the mobile installation frame 1, the knocking component 4 includes a rotating shaft, a winding wheel, a pulley and a knocking block, a pulley component 3 is connected between the knocking component 4 and the output shaft of the driving motor 2, the pulley component 3 includes a pulley and a transmission belt, a mounting seat 5 is connected to the left side of the mobile installation frame 1, a contact platform 6 that contacts the knocking component 4 is connected to the mounting seat 5, and a side vibration mechanism 7 for auxiliary knocking on the building wall is set between the mobile installation frame 1 and the contact platform 6.

[0022] like Figure 2-Figure 4 As shown, the side vibration mechanism 7 includes a guide rod 71, two guide rods 71 ​​are connected to the left top of the movable mounting frame 1, a toggle frame 72 is slidably arranged between the guide rods 71, the toggle frame 72 is connected to the knocking assembly 4, a mounting plate 73 is connected to the left side of the contact table 6, knocking pieces 74 are slidably arranged on the front and rear parts of the mounting plate 73, the right part of the knocking piece 74 is provided with an inclined surface structure, a first spring 75 is connected between the knocking piece 74 and the mounting plate 73, the right part of the knocking piece 74 can contact with the toggle frame 72, the front and rear sides of the right part of the mounting plate 73 are connected with a wedge-shaped kit 76, the wedge-shaped kit 76 can be squeezed and limited by the toggle frame 72, a second spring 77 is installed on the wedge-shaped kit 76, and the outer end of the wedge-shaped kit 76 can be clamped with the adjacent knocking piece 74.

[0023] It should be noted that the earthquake-resistant structure of a building refers to a structural system and technology designed for use in building design and construction to cope with the vibrations and impacts that may be caused by geological disasters such as earthquakes. Therefore, it is necessary to ensure the earthquake-resistant effect of the earthquake-resistant structure of the building. When conducting an earthquake-resistant effect test, the present device can be used to assist in the test. First, the mobile installation frame 1 is moved to the specified test position, and then the drive motor 2 is started. The rotation of the output shaft of the drive motor 2 will drive the pulley assembly 3 to operate, so that the rotating shaft in the knocking assembly 4 drives the winding wheel to rotate, and then the pull rope is wound up. In the process of the knocking block lifting upward, the toggle frame 72 will be synchronously driven to slide upward along the guide rod 71, so that the toggle block toggle the knocking piece 74, so that the knocking piece 74 slides to the right. At this time, the first spring 75 will be compressed by force. At the same time, in the process of the toggle frame 72 lifting upward, the wedge kit 76 is no longer limited by the toggle frame 72, and the initial The second spring 77 is in a stressed and compressed state. At this time, under the action of the second spring 77, the wedge-shaped kits 76 will be extended and opened, thereby engaging with the knocking piece 74 after sliding to the right, completing the fixation of the knocking piece 74, and then controlling the output shaft of the drive motor 2 to rotate in the opposite direction, so that the pulley assembly 3 rotates in the opposite direction. At this time, the pull rope is released, and the knocking block will directly fall and knock on the contact platform 6, and then transmit the knocking force to the earthquake-resistant structure of the building. At the same time, as the knocking block falls rapidly, the toggle frame 72 will also slide downward and reset synchronously, thereby squeezing the wedge-shaped kit 76 again, so that the wedge-shaped kit 76 is reset, and the second spring 77 returns to the stressed and compressed state. At this time, the knocking piece 74 is no longer locked by the wedge-shaped kit 76, and under the action of the first spring 75, the knocking piece 74 will slide back to the left quickly and reset, and the side wall of the building structure will be synchronously knocked, thereby improving the accuracy and comprehensiveness of the knocking test.

The telescopic ends of the hydraulic cylinders 81 are both set downward, and a support plate 82 for fixed support is connected between the telescopic ends of the hydraulic cylinders 81.

[0026] It should be noted that in order to improve the stability during the test, when the mobile installation frame 1 moves to the specified position, the hydraulic cylinder 81 can be started, and the telescopic end of the hydraulic cylinder 81 extends downward, thereby causing the support plate 82 to move downward, replacing the moving wheels on the mobile installation frame 1 to contact the plane, making the device more stable.
